DETAILED DESCRIPTION OF THE INVENTION

(12) For the sake of simplicity, elements having substantially the same function and/or the same structure in the different modes of implementation that will be presented bear the same reference signs.

(13) The building of a protective structure according to a first mode of implementation of the invention will now be presented in relation to FIGS. 1A-1E, 2, 3 and 4.

(14) The protective structure is assembled by transferring panels 20 gradually from a container 30 all the way to a carrying structure 10. The transfer is done by moving the panels along a horizontal axis of assembly X, starting from the moment when the panels are placed bearing on the carrying structure.

(15) Although this will not be further detailed below, all the components implemented are symmetrical with respect to the vertical plane containing the axis of assembly X.

(16) The main constituents of the protective structure are a carrying structure 10 and panels 20. The panels are collectively referred to as panels 20; they are also individually referenced as panel 201, panel 202, etc.

(17) The carrying structure 10 can be made in many ways: it can be a metal, wooden, inflatable, composite structure etc.

(18) In the example presented the structure is metal, and is mainly formed by a set of rails assembled together, in a manner known per se.

(19) These rails mainly divide into two carrying rails 12, supported by a certain number of vertical posts 14 attached to the ground.

(20) The carrying rails 12 are mutually parallel metal profiles, disposed horizontally. In other embodiments, there can be three parallel carrying rails, or even more. The carrying rails 12 in particular have the function, when the panels are in the final position on the structure, of holding the panels in place and supporting the weight of the panels, and preventing them from flying off.

(21) In addition, as will be explained, the carrying rails 12 serve to guide and support the panels 20 during their transfer to the final position.

(22) In the present case, provision is made for the rails 12 at the lateral ends of the panels; they could also be found at intermediate positions along the width of the panels (the width is measured along the direction perpendicular to the direction of assembly X shown in FIG. 1A).

(23) In other embodiments, provision can be made for an additional carrying rail at mid-distance between the lateral ends of the panels, to reduce the cantilever.

(24) The panels 20 are rectangular photovoltaic panels.

(25) Initially, at the beginning of the building of the protective structure, all the panels 20 are disposed mutually parallel in a container 30, in the storage position. The container 30 is a container having standard dimensions and external features for road, sea or rail transportation.

(26) In the container 30, the panels are disposed vertically (the direction perpendicular to the panels is horizontal; more precisely, it is oriented along the direction of assembly X). The sides of the panels which are intended to be disposed on the front side (along the direction of assembly X) are disposed at the top (on the upper side of the panels).

(27) The container 30 includes four storage rails, namely two upper storage rails 34sup, and two lower storage rails 34inf.

(28) In this example, all the panels 20 are identical.

(29) Each panel 20 is equipped with four supports 22, namely two front supports 22A and two rear supports 22B (FIG. 2, 3). Each support 22 mainly comprises a wheel (front wheels 24A, rear wheels 24B) and a hub attached to the panel 20. The two wheels 24A of the supports 22A are linked by a shaft 26A attached to the front of the panel 20 which forms the hub shared by the two front wheels 24A. The two wheels 24B of the supports 22B are linked by a shaft 26B attached to the rear of the panel 20 which forms the hub shared by the two rear wheels 24B.

(30) Naturally, other types of support can be chosen as supports for the panels 20: carriages each including several wheels, skids configured to slide in or on the carrying rails, etc.

(31) In the container 30, the front side of each of the panels is linked to the front side of the panel which follows it by two cables (one cable on the left side, one cable on the right side). These cables are collectively referred to as cables 21; they are also referenced by pairs: cables 211 for the panel 201, cables 212 for the panel 202, etc.

(32) Each of the carrying rails 12 is a metal profile of constant section, having the general shape of the letter ‘C’ to allow the wheel shafts to pass over a lateral face. The section of these rails has two wheel passages 14, 15. The lower part of these wheel passages 14 and 15 respectively includes a first rolling surface 141 and a second rolling surface 151.

(33) Each of the wheel passages 14, 15 is closed toward the top by a horizontal wall (142, 152 respectively). The walls 142 and 152 jointly form a fly-off prevention part of the carrying rails 12, insofar as they prevent the wheels 24A, 24B from moving upward (except for a certain amount of play naturally), and thus prevent the panels from moving upward, and thus flying off if a gust of wind lifts them.

(34) The storage rails 34sup, 34inf have the same section as the carrying rails 12.

(35) When the protective structure is built, as soon as the panels are placed in the insertion position, their wheels 24A, 24B are bearing on the rolling surfaces 151 and 141 respectively. Thus, the four angles of each panel are bearing (via the wheels 24A, 24B) on the carrying rails 12, whether in the insertion position, in the final position, and at each instant during the movement of the panels from the moment that they are in the insertion position. Owing to these bearings at the four angles, in these different positions the front side and the rear side of the panels rests on the carrying rails 12 via bearing points which are the bearing points of the wheels 24A, 24B on the rolling surfaces 151 and 141.

(36) The transfer of the panels 20 from the container 30 to the carrying structure 10 is done using a transfer device 40.

(37) The transfer device 40 mainly includes transfer rails 42sup and 42inf, two ramps 44 and a hoist 50.

(38) The transfer rails 42sup and 42inf are rails having the same section as the carrying rails 12.

(39) The transfer rails 42sup are disposed at the same height as the carrying rails 12 and the storage rails 34sup. They continuously link the storage rails 34sup to the carrying rails 12.

(40) The transfer rails 42inf are disposed at the height of the lower sides of the panels; thus in the storage position, the rear wheels 24B of the panels are found in the wheel passages of the transfer rails 42inf.

(41) The transfer device 40 further includes a hoist 50, attached at the top part of the container 30 and equipped with a cable 52 exerting a pull.

(42) The different steps of the method for building the protective structure will now be presented in relation to FIGS. 1A-1E, 2 and 3 and the diagram of FIG. 4.

(43) In step a), the carrying structure 10 is built from its different components.

(44) In step b), the container 30 is supplied, containing the panels 20 shelved vertically side by side in the container 30. Each of the panels 20 is bearing both on its rear supports 22B (the rear wheels 24B are disposed in the first wheel passages 14, bearing on the rolling surfaces 141 of the lower storage rails 34inf) and the front supports 22A (the front wheels 24A are disposed in the second wheel passages 15, bearing on the rolling surfaces 151 of the upper storage rails 34sup).

(45) In step c), the transfer device 40 is put in place.

(46) In step d), the panels 20 are transferred from their storage position in the container 30 to a final position wherein all the panels are supported by the carrying rails 12.

(47) This transfer is done by performing (optionally iteratively) the following operations in such a way as to transfer all the panels 20:

(48) d1) one of the panels 20 is transferred from the storage position to an insertion position wherein the panel under consideration is bearing on the carrying rails 12;

(49) d2) simultaneously, the panels already bearing on the carrying rails are moved along them, along the direction of assembly X.

(50) The transferred panels are placed one after the other bearing on the carrying rails 12 and little by little form a panel train 60 bearing on the carrying rails 12.

(51) At the start of step c), the cable 52 of the hoist 50 is deployed such that the cable 52 passes through a return pulley 54 attached to the front of the structure 10, and comes back to a fastening point P located in the middle of the front side of the first panel 201. Using the hoist 50, the front panel 201 is pulled using the cable 52. Under the effect of the pull that is applied to it, the front panel 201 puts itself in place on the carrying rails 12 in the engaged position. It then forms the first element of a “panel train” 60 which will gradually be formed to make the protective structure.

(52) Once the front panel 201 has been put in the insertion position, the following panels are all assembled in the same way.

(53) The transfer of a panel 202 (by way of example) from its assembly position to its insertion position at the rear of the panel train (step c1) will now be explained in relation to FIGS. 1B-1E. These figures show four successive times t1, t2, t3 and t4 of the transfer of the panel 202 from its storage position to its insertion position on the carrying structure 10.

(54) Time t1 (FIG. 1B)

(55) At the time t1, the transfer of the panel 201 from its storage position to its insertion position is almost finished; conversely, the transfer of the panel 202 is beginning.

(56) At this stage, the panel 202 has just separated from the panel 203 (which is still in the storage position). The front side of the panel 202 is drawn by the cables 211, which are fastened on the front side of the panel 201. Under the effect of this pull, the front side of the panel 202 moves forward (in the direction of assembly X).

(57) The front wheels 24A of the panel 202 after having briefly rolled on the upper storage rail 34sup are now bearing on the transfer rail 42sup; and the rear wheels 24B of the panel 202 after having briefly rolled on the lower storage rail 34inf and having passed onto the transfer rail 42inf, have just become engaged on the ramps 44. The cables 212 linking the front side of the panel 202 to the front side of the panel 203 are not yet taut.

(58) Time t2 (FIG. 1C)

(59) The rear wheels 24B of the panel 201 have just passed through the insertion openings 16 (FIG. 2) for which provision has been made on the lower face of each of the transfer rails 42sup and are now bearing on the rolling surfaces 141 of the first wheel passages 14. The panel 201 has therefore reached its insertion position, bearing on the carrying rails 12.

(60) The transfer of the panel 202 toward its insertion position is in progress. In the course of this motion, the panel 202 is lifted by the transfer device 40, due to the fact that its rear wheels 24B are elevated by rolling on the ramps 44 which rise toward the rails 12, whereas its front wheels 24A roll forward (along the direction of assembly X) in the second wheel passage 15 of the rails 42sup.

(61) During the transfer of the panel 202, the cables 212 linking the front of the panel 202 to the front of the panel 203 gradually tauten. As soon as they are taut, the panel 203 begins to move forward (in the direction of assembly X, FIG. 1A); its front/rear wheels first roll along the storage rails 34sup/34inf, then along the transfer rails 42sup/42inf.

(62) Time t3 (FIG. 1D)

(63) The front panel 201 (which at this stage forms the panel train 60) continues to be drawn forward using the hoist 50, via the cable 52.

(64) The panel 202 is on the point of reaching its insertion position, its rear wheels 24B rise again on the ramps 44 but have not yet passed through the openings 16 and are not yet in the first wheel passage 14 of the carrying rails 12.

(65) The panel 203 is in the process of being transferred, under the effect of the pull that is applied to it by the cables 212; its rear wheels have just become engaged on the ramps 44.

(66) The panel 202, then behind it the panel 203, pivot little by little in the course of their respective transfers, while elevating, and gradually and successively put themselves in the horizontal position at the level of the carrying rails 12.

(67) Time t4 (FIG. 1E)

(68) The panel 202 has just gone past its insertion position and is now incorporated into the panel train 60. The latter is therefore at this stage formed by the panels 201 and 202, and moves along the direction of assembly X. Just behind the panel 202, the panel 203 has performed most of its transfer, and the panel 204 has itself begun to move under the effect of the pull that is applied to it by the cables 213.

(69) In the course of its transfer, the panel 202 moves only under the effect of the pull that is applied to it by the cables 211 (it being noted that its wheels 24A and 24B remain bearing at all times on the storage rails, the transfer rails, the carrying rails and/or the ramps, according to the case).

(70) The length of the cables 21 is computed such that in the insertion position, the front side of a panel 20 is just behind the rear side of the preceding panel 20. The cables 21 form connectors within the meaning of the invention and are formed from a non-extensible material (metal for example).

(71) In this mode of implementation, the operations d2) of movement of the panel train 60 and the operations d1) of transfer of the panels 20 occur at the same time. During the transfer of a panel 20 from its initial position to its insertion position, the panel train 60 moves by substantially the length of one panel (along the direction of assembly X).

(72) All of the panels 20 are thus successively drawn out of the container 30 and placed in the insertion position. Each panel 20, as soon as it reaches its insertion position, may be considered as being incorporated into the ‘panel train’ 60. It is then gradually moved forward as the hoist 50 pulls the cable 52.

(73) As the wheels 24A, 24B of each of these panels 20 roll on the rails 12, the panels of the train 60 can move easily along the rails 12 along the direction of assembly X.

(74) Thus, under the effect of the pull, all of the panels 20 are successively taken out of the container 30 and placed in the final position on the carrying structure 10.

(75) Advantageously, the operations of assembly of the panels are reversible. It is thus possible to dismantle the protective structure easily and quickly by performing the reverse operations of the operations d1) and d2).

(76) The supports 22 of the panels serve both as means for supporting the panels in the storage position in the container 30 and means for supporting and guiding, during the transfer of the panels 20 from their storage position to their insertion position and all the way to their final position on the structure 10.

(77) In addition, the supports 22 also serve as supports for holding the panels. Specifically, when a panel 20 is engaged on the carrying rails 12, as the wheels 24A and 24B respectively are compelled to move only along the direction X through the wheel passages 14 and 15 of the carrying rails 12, this prevents (except for the play) any forward or rearward motion of the panels downward and upward with respect to the carrying rails 12.

(78) In this position, owing to the supports 22 resting directly on the rails 12, the front side and the rear side of the panels are bearing on the carrying rails 12, but without the panel 20 bearing, even partly, either on the front side or the rear side, on an adjacent panel.

(79) The building of a protective structure according to a second mode of implementation of the invention will now be presented in relation to FIGS. 5A to 5D.

(80) This mode of building is quite similar to the mode of building presented previously. Hence, unless otherwise specified, it should be considered that the second mode of implementation is identical to the first mode of implementation.

(81) In this mode of implementation, the panels 20 are stored horizontally in the container 30 and form a stack of panels 200.

(82) The panels 20 in this mode of implementation are slightly different from the panels 20 of the first mode of implementation.

(83) In the present case, each of the panels 20 includes front supports 22A which are identical to the front supports 22A of the first mode of implementation.

(84) On the other hand, the rear side of each of the panels 20 includes specific supports 22B, which are formed by hooks, collectively referred to as hooks 22. Each panel 20 thus includes two hooks attached at the two ends of its rear side. (The panel 201 includes two hooks 221, the panel 202 two hooks 222, etc.)

(85) The hooking of a panel 20 to the preceding panel is therefore not done using the cables 21 as previously, but using the hooks 22.

(86) FIGS. 5B, 5C and 5D show three steps of the hooking of the panel 204 to the panel 203. The panel 204 is linked or hooked to the panel 203 at the start of its transfer to the insertion position, using two hooks 223 attached to the panel 203.

(87) On the rear side, each hook 223 has a part in the shape of a hook curved downward; each hook 223 is thus shaped in such a way as to be able to hook onto the shaft 26A of the front wheels 24A of the following panel 204, the shaft 26A passing with this aim through a ‘shaft passage’ 28 fashioned in the hook 223.

(88) The transfer device 140 used to transfer the panels 20 from the container 30 all the way to their insertion position on the carrying structure 10 is naturally configured to allow this mode of hooking of the panels.

(89) This transfer device 140 includes a hoist 150 as the sole actuator: this hoist first of all serves, as previously, to pull the panels of the panel train 60 along the direction of assembly X using the cable 52, along the direction F; but in addition, the hoist 150, in combination with a set of cables 152 and a tray 154, forms an elevator which makes it possible to lift or hoist the stack of panels 200 upward.

(90) Another special characteristic of this mode of implementation is that the carrying rails 12 extend all the way to the container 30; there are no transfer rails.

(91) The building of the protective structure is done in the following manner.

(92) In a first step a), the carrying structure 10 is built.

(93) Moreover (step b), the stack of panels 200, stored in the container 30, is supplied.

(94) The transfer device is then put in place (step c).

(95) Then in a step d), the panels 20 are transferred from their storage position in the container 30 to a final position on the carrying structure 10.

(96) At the very start of step d), the cable 52 is fastened to the hoist 50 on the front side of the panel 201, passing through the pulley 54.

(97) The following operations are then performed: the stack of panels 200 is hoisted in such a way as to carry the panel located at the top of the stack, the so-called ‘upper panel’, at the level of the carrying rails 12. in the case of the first panel 201, the front wheels 24A thereof are engaged in the carrying rails 12; for each of the following panels, the rear side of the last panel engaged on the rails is hooked to the front side of the following panel.

(98) This hooking operation is illustrated by FIGS. 5B, 5C and 5D, which show the hooking of a ‘second panel’, the panel 204, to a ‘first panel’, the panel 203: the first panel 203 is slowly drawn forward (along the direction of assembly X) using the hoist 150 until the hooks 223 begin to pass over the front side of the remaining panels in the container.

(99) This location corresponds to the time t1 shown in FIG. 5B. Simultaneously, the stack of panels 200 is made to rise (rising vertical direction indicated by the arrow U).

(100) These two motions are coordinated such that on each side of the panels 203 and 204, the shaft 26A can engage in the shaft passage 28.

(101) At the time t1 (FIG. 5B), the shaft 26A of the front wheels 22A of the panel 204 arrives just below the opening of the shaft passage 28 fashioned in the hook 223. The horizontal movement of the panel 203 and the vertical motion of the stack of panels 200 continue such that the shaft 26A becomes engaged in the shaft passage 28. At the time t2 shown in FIG. 5C, the shaft 26A is engaged in the passage 28.

(102) Immediately afterwards, the hoist 150 is disengaged from the cables 152, such that the stack of panels 200 stops rising at the moment the shaft 28 reaches the top of the passage 28.

(103) Conversely, the panel 203 continues to be drawn forward by the cable 52. The shaft 26A therefore is therefore locked behind the passage 28 (FIG. 5D). In this position, the panel 204 is hooked to the panel 203: as the panel train continues to be pulled forward, the panel 204 also moves forward, in such a way as to come to the insertion position on the carrying rails 12, to be incorporated into the panel train. It is then moved on the carrying rails 12 until it reaches its final position.

(104) This procedure is repeated identically for the different panels. The operations of hooking of the different panels (steps c1) are therefore performed successively while the panel train 60 is moved (step c2) in such a way as to transfer all the panels 20 all the way to their final position on the carrying structure 10.

(105) Advantageously in this mode of implementation, the hoist 150 serves to both draw the panel train 60 along the direction of assembly (horizontal movement of the panels) and to lift the stack of panels 200 upward (vertical movement or lifting of the stack of panels).

(106) A special characteristic of this mode of implementation is that the rear side of the panels 20 does not include any supports 22B (of wheels 24B). In the container 30, the panels 20 are only supported by their front supports 22A (with the exception of the last panel naturally).

(107) Thus each panel, with the exception of the last panel, includes only front supports 22A, and no rear supports. The rear side of each panel is therefore configured in such a way as to rest, by way of the hooks 22, on the following panel (which is adjacent). Thus it is the following panel, and more precisely the front supports 22A of the following panel, that provide the holding of the rear side of the panel under consideration along the vertical direction (both upward and downward).

(108) The building of a protective structure according to a third mode of implementation will now be presented in relation to FIG. 6. This third mode of implementation is quite similar to the first building mode presented previously. Also, unless otherwise specified, it should be considered that the third mode of implementation is identical to the first mode of implementation.

(109) In this mode of implementation, the panels 20 are stored vertically side by side in the container 30. They are also linked to one another by cables 21 identical to the cables 21 used in the first mode of implementation.

(110) The steps a), b), c) and d) of building the protective structure are substantially identical to the corresponding steps of the first mode of implementation.

(111) The main special characteristic of the third mode of implementation pertains to the transfer device 240 used to move the panels 20 from the container 30 to the carrying structure 10.

(112) Specifically in the first mode of implementation, the transfer device 40 includes ramps 44 which lift the rear wheels 24B of the panels 20. These ramps form a part of the transfer rails which is in the inclined position.

(113) By contrast in the third mode of implementation, the transfer device 240 includes lifting bars 23 which have the purpose of lifting the panels 20 upon their transfer to the insertion position.

(114) These bars (collectively, the bars 23) are individually referenced as bar 231, bar 232, bar 233 and bar 234, following the order wherein they interact with a panel to lift it gradually, when the protective structure is assembled.

(115) These bars 23 form bearings secured to the carrying structure 10 and are in practice attached to the carrying structure 10.

(116) These are horizontal bars, perpendicular to the direction of assembly, and which are disposed at increasing heights on the front side of the container 30.

(117) The heights of the bars 23 are set such that during step c1), the panels come successively into contact with the bars 231, 232, 233 and 234, which obliges the panel or panels 20 in the process of being transferred to lift.

(118) FIG. 6 shows an intermediate position reached by the panel 204 during its transfer onto the carrying structure.

(119) This transfer happens as follows.

(120) The transfer of the panel 205 (by way of example of a panel) begins when the cables 214 of the panel 204 are tautened. The panel 205 is then drawn by the panel 204, itself incorporated into the panel train 60 and drawn by the hoist 50. The front side of the panel 205 is drawn forward; its front wheels 24A roll on the storage rails 34sup then on the transfer rails 42sup then on the carrying rails 12.

(121) At a certain time, the panel 205 comes into contact with the first lifting bar 231, which is the lowest. As the front side of the panel 204 continues to progress forward (direction of assembly X) the panel 205 is therefore obliged to lift.

(122) When the movement of the front side 204 continues, the panel 205 then comes successively into contact with the lifting bars 232, 233 and 234, which obliges it to lift more and more, until it finally reaches the horizontal position; the front and rear wheels of the panel 205 are then bearing in the wheel passages 14 and 15, and the panel 205 is in the insertion position.

(123) In the course of this movement, the panel 205 pivots. The position of the insertion openings 16 on the transfer rails 42sup is disposed such that the rear wheels 24B of the panel 205 (or of the other panels) during the transfer can enter into the wheel passages 14, as in the first mode of implementation.

(124) In the first as in the third mode of implementation, it is the reaction force applied to the panels by bearings secured to the structure (ramps 44 and lifting bars 23 respectively) which causes the panels 20 to lift and reach the insertion position. Naturally, these bearings can take many forms as shown by the examples of the first and the third modes of implementation.

(125) The building of a protective structure according to a fourth mode of implementation will now be presented in relation to FIG. 7. This fourth mode of implementation is for the most part similar to the first building mode presented previously. Hence, unless otherwise specified, it should be considered that the fourth mode of implementation is identical to the first mode of implementation.

(126) In this mode of implementation, the panels 20 are stored vertically side by side in the container 30.

(127) Moreover, unlike the preceding embodiments, they are linked to one another, even in the storage position. More specifically, for each panel, the rear side of the panel is linked to the front side of the following panel. The panels are thus linked in a ‘zig-zag’ formation in the container 30.

(128) Consequently during the building of the protective structure, when a panel is placed bearing on the carrying rails 12 and incorporated into the panel train, and when it is drawn forward, it drags after it the following panel, which itself drags the following panel, and so on (See FIG. 7).

(129) The link can be made by any means. In the proposed example, each panel 20 is identical to the panels 20 of the first embodiment; it therefore includes supports 22A and 22B identical to the supports 22A and 22B of the panels used in the first mode of implementation, and shown in FIGS. 2 and 3.

(130) When they are transferred, the panels 20 are held and lifted by their front 24A and rear 24B wheels in substantially the same way as in the first mode of implementation:

(131) On the upper side, the front wheels 24A roll successively bearing on the storage rails 34sup, then the transfer rails 42sup, then the carrying rails 12; on the lower side, the rear wheels 24B roll bearing on the lower storage rails 34inf, the lower transfer rails 42inf, the ramps 44, and then the carrying rails 12.

(132) In the course of this motion it can occur that the wheels of certain panels are temporarily lifted above the transfer rails 42inf, the panels of which these wheels are a part then being supported only by their wheels bearing on the upper transfer rails 42sup; but be that as it may, the presence of the ramps 44 guarantees that the panels reach the insertion position, with engagement of their rear wheels on the transfer rails 42sup.

(133) A detail view in FIG. 7 shows a part of the lower end of the panels 205 and 206.

(134) As long as the panels 205 and 206 are not disposed substantially in the same plane, each of the rear wheels 24B of the panel 205 is in contact with a corresponding front wheel 24A of the panel 206. The shafts 26B and 26B respectively of these two wheels are linked to one another by a link 225. (Any other linking device, preferably non-extensible, could be suitable, for example a hook linking the shaft 26A of the panel 206 to the shaft 26B of the panel 205, etc.).

(135) Owing to the links 225, when the panel 205 is transferred toward its insertion position, then toward its final position, it drags the panel 206 after it.

(136) The building of a protective structure according to a fifth mode of implementation of the invention will now be presented in relation to FIGS. 8A to 8C.

(137) This embodiment is identical to the first embodiment (FIGS. 1A to 1E), with the exception of the differences explained below.

(138) In the first embodiment, the transfer device comprises inclined ramps 44. During the transfer of the different panels, the rear wheels 24B of the panels take bearing on these ramps 44, which obliges the panels to lift.

(139) In the fifth mode of implementation, the transfer device 440 differs from the transfer device 40 in that it does not include any inclined ramps 44. Instead, on each upper transfer rail (42sup) is assembled a mast 46. On this mast is assembled a double-groove pulley 47. Two identical slings 48A and 48B are used in association with the pulley 47, in the manner indicated by FIGS. 8A-8C:

(140) During the transfer, for example, of a first panel 201 (FIG. 8A), the ends of one of these slings (the cable 48A) have been previously attached to the front and rear sides of this first panel; for example, to the shafts 26A,26B of the wheels 24A,24B. (The same operations are performed on the left and the right side of the panels). The sling 48A therefore has a first strand 48A1 located between the pulley 47 and the front side of the panel 201, and a rear strand 48A2 conversely located between the pulley 47 and the rear side of the panel 201.

(141) In parallel, the ends of the other sling (sling 48B) have been previously attached to the front and rear sides of the second panel 202, in the same way as the first sling 48A.

(142) As in the first embodiment, the panel 201 is drawn forward, i.e. along the direction of assembly, by the cable 52. Under the effect of this pull, its front wheels engaged on the carrying rails 12 move forward by rolling horizontally on these rails. Thus, the front end of the sling 48A linked to the front of the panel 201 moves forward, which increases the length of the front strand 48A1 and conversely reduces the length of the rear strand 48A2. This change obliges the rear of the panel 201 to rise, while moving forward. After this motion (FIG. 8B), the panel 201 has reached a horizontal position, which is the insertion position, wherein the rear wheels 24B engage on the carrying rails 12. The sling 48A is then detached from the panel 201 and attached to the third panel 203.

(143) At the same time, the second panel 202 is drawn forward by the cable 211. Like the first panel, while the front wheels 24A of the second panel 202 roll forward on the rails 12, the rear of the second panel gradually lifts under the effect of the pull that is applied to it by the rear strand 4862 of the sling 48B (FIG. 8C). In the subsequent step (not shown), after this lifting motion the panel 202 reaches the insertion position; the sling 48B is detached.

(144) These operations are executed successively until all the panels have been placed in the final position on the rails 12.

(145) In the different modes of implementation presented, the panels 20 are photovoltaic panels. To implement photovoltaic panels, these must naturally then be electrically connected to an electricity conditioning and/or storage facility.

(146) Moreover, the invention can naturally be implemented with all types of panels, in particular panels without photovoltaic modules.

(147) The putting in place of the panels according to the invention generally forms only the first phase of the building of the protective structure. The building of the protective structure generally includes other subsequent fit-out steps, for example: Installing seals or other means between the panels, or putting a tarpaulin in place under the panels, to seal the roof formed by the panels; Installing or producing vertical walls on the sides of the carrying structure, in order to close the internal space fashioned under the panels.

(148) Although in the modes of implementation presented, the pulling force applied to the panel train is applied by a hoist, other means can be used. For example, the panel train can be moved, and in particular pulled, by a truck or an agricultural tractor.
