Description

[0022] The invention will be explained in more detail in the following text with reference to an exemplary embodiment shown purely schematically in the drawings. In the drawings:

[0023] FIG. 1 shows a front view of a device for shore power supply along the sectional plane I-I of FIG. 2;

[0024] FIG. 2 shows the device for the shore power supply of FIG. 1 in a first position on a quay wall and

[0025] FIG. 3 shows the device for the shore power supply of FIG. 1 in a second position on the quay wall of FIG. 2.

[0026] FIG. 1 shows a device 1 for connecting a ship, not illustrated in any more detail, to a shore-based power supply network. An essential component of the device 1 is a shore-based coupling unit 2, which is movable along a quay wall 3 in a rail-guided manner. For this purpose, the coupling unit 2 has a travelling mechanism 4 with wheels 5, 6 which run parallel to one another and which are arranged in two tracks 7, 8 at a horizontal distance from one another. In this case, there are 2 wheels 5, 6 per track 7, 8. One track 8 is located above the quay wall 3 or on the quay. This track 8 is non-rail-guided. The second track 7 is located on the waterway side of quay wall 3. Specifically, the second track 7 is located above the waterway, that is to say on the side of the quay wall remote from the shore. The second track 7 is not located on, but spatially in front of the quay wall 3 as viewed in the horizontal direction from the waterway. For this purpose, a rail 9 is arranged on the waterway side of the quay wall. In particular, the rail 9 does not protrude or protrudes only slightly above the top side 10 of the quay wall 3. The tracks 7, 8 are preferably at the same height. The rail 9 is arranged at the upper end of the waterway side of the quay wall 3.

[0027] The travelling mechanism 4, which carries the wheels 5, 6, is configured so that mooring apparatuses 11 in the form of bollards projecting from the top side 10 of the quay wall 3 can overlap the top side and thus also be driven over. To this end, the wheels 5, 6 are arranged at a greater distance from a platform 12, underneath which the travelling mechanism 4 is located. The travelling mechanism 4 comprises stilt-like struts so that the platform 12 can be guided with sufficient ground clearance between the tracks 7, 8 and at a sufficient vertical distance over the mooring apparatuses 11.

[0028] The platform 12 has at least one drive. A drive is provided for moving the coupling unit 2 in the longitudinal direction of the rail 9. A further drive is used to drive a line drum 15 with double spiral winding. Two electrical power supply lines 16, 17 are arranged parallel to one another on the line drum 15.

[0029] The power supply lines 16, 17 are used to supply shore power to the ship, which is not illustrated in any more detail. The line drum 15 is not located physically perpendicular above the quay wall 3, but next to the quay wall 3 just like the rail 9 on the waterway side. The drive for the line drum 15 and the travelling mechanism serve as a counterweight. The line drum 15 protrudes downwards between the wheels 5 of the rail-side track 7.

[0030] The power supply lines 16, 17 are placed by unwinding from the line drum 15 in annular channels 18, 19 which are open at the top. One of the channels 18 is located below the rail 9. This channel 18 and the rail 9 form one component. The wheel 5 is wider than the channel 18 which is open at the top. The wheel 5 rolls, on the mouth side of the channel 18 which is open at the top, over laterally outwardly oriented and horizontally oriented flanges 20, 21, which form the contact surface for the wheel 5. Inner and outer guide bars 22, 23 which project upwards in the plane of the image are arranged on the flanges 20, 21 for the lateral guidance of the wheel 5. The shore-based coupling unit 2 has multiple consecutive wheels per track in the track direction, such that the coupling unit 2 is movable only in the longitudinal direction of the track 7.

[0031] FIG. 2 shows the position of a sectional plane I-I, which illustrates the direction of view of FIG. 1. The power supply line 16 is connected at a connection point 25 to a shore-based end 24. A second connection point 26 is provided for the second power supply line 17 (FIG. 1). The connection points 25, 26 are located below the channels 18, 19, as can be seen in FIG. 1. The two power supply lines 16, 17 are routed, starting from their connection point-side ends 24, 25 coming from below through a line diverter 27. The line diverter 27 has rounded cheeks on the top side, such that the power supply lines 16, 17 can be moved to the left and right in the image plane of FIG. 2 with a large bending radius without kinking.

[0032] According to the illustration of FIG. 2, the shore-based coupling unit 2 can be moved in the direction of the arrow 28 along the quay wall 3 until an end position is reached. The power supply lines 16, 17 are placed in channels 18, 19 so as to be protected. If another ship which has moored in the image plane of FIG. 2, to the right of the connection point 25, 26, is to be supplied with power, the shore-based coupling unit 2 can be moved in the opposite direction, that is to say in the direction of the arrow 29 of FIG. 3. The shore-based connection point is then located on the left in the image plane of FIG. 3. In this case, too, the power supply lines 16, 17 can be routed so as to be protected in the channels 18, 19 which are open at the top. The mooring apparatuses 11 can be traversed by the travelling mechanism 4 and the platform 12 of the shore-based coupling unit 2 due to the adapted large ground clearance, as can be seen in FIG. 1.

[0033] FIGS. 1 to 3 show additional protective apparatuses for protecting the rail 9 and channels 18, 19 arranged on the waterway side and for protecting the connection points 25, 26. The protective apparatuses include an impact protection system 30. Several of the impact protection systems 30 are arranged at a distance from one another along the quay wall 3. They are essentially configured in an L-shaped manner, as can be seen from the sectional illustration of FIG. 1. They engage under the rails 9 and the connection points 25, 26 towards the water level of the waterway and have a vertically upwardly projecting limb 31, which overhangs the rails 9 and connection points in the upward direction. The vertical limb 31 may be offset at its upper end towards the shore in order to improve the protective effect. The vertical limb 31 extends at a horizontal distance A1 from the centre rail 9 or the connection points 25, 26 in order to create a sufficient crumple zone of at least 250 mm, even in the event of an accident.
