DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) The preferred embodiments and technical contents regarding the present invention will be described along with drawings as follows. Firstly, referring to FIG. 1 and FIG. 2 together, there are shown partial side cross-sectional view and top plan view according to a first preferred embodiment of the present invention. As clearly seen from the figures, the present invention proposes a driving structure for a power generator along a coastal land using kinetic energy of wave. The driving structure using kinetic energy of wave 10 is used for driving the power generator 50 provided along the coastal land 80. The power generator 50 is then operated via the upward and downward swing of a toggle lever 60 to generate electricity. In this case, the driving structure using kinetic energy of wave 10 is provided with a wave-guiding channel 20 for constraining the flow direction of waves 90. The wave-guiding channel 20 is provided with two side walls 22, an end portion 23 connecting the two side walls 22, and an intake 25 facing and opening toward the ocean, so as to form a gully 24 eventually closed by the end portion 23. At the top of each of the two side walls 22, an extending portion 221 extending upward is provided, respectively, near the end portion 23. The extending portion 221 is pivotally provided with a pivot 40. Further, the driving structure using kinetic energy of wave 10 is further provided with a floating body 30 located in the gully 24 and close to the end portion 23. The floating body 30 is extendingly provided at one end thereof with a coupling portion 31 pivotally connected to the pivot 40, and provided at the other end thereof with an abutting portion 32 abutted against the toggle lever 60 normally. In this case, the floating body 30 is provided inside thereof with a hollow portion 33, so as to facilitate the enhancement of buoyance of the floating body 30. Among others, the gully 24 is provided at the bottom thereof with a bottom portion 21 with drainage gradient ranging from 1/100 to 3/100, so as to facilitate smooth discharge of waves 90 in the undertow from the gully 24. Among others, however, the intake 25 is formed by tapering the spacing, between the two side walls 22, from the outside of the intake 25 toward the interior of the intake 25, so as to facilitate the gully 24 to receive a larger number of waves 90 initially, in such a way that more kinetic energy is generated and greater difference in water levels is achieved. In addition, in regard to the power generator 50, it is generally to provide a cover body 51 outside of the power generator 50, and install a stand 52 under the cover body 51. Thus, it is possible to ensure that the power generator 50 is not soaked in or corroded by seawater. Certainly, it is also possible to provide a chassis 53, fixedly provided on the coastal land 80, under the stand 52, such that the power generator 50 may be provided more stably. Finally, the driving structure using kinetic energy of wave 10 of the present invention is used for driving the power generator 50, such that a ratchet wheel 70 or one-way bearing may be provided between the toggle lever 60 and the power generator 50 for driving the power generator 50 unidirectionally. Namely, damage to the mechanism due to reversely driven the power generator 50, when the toggle lever 60 is turned downward under the self-gravity to operate reversely, may be avoided.

(7) Again, referring to FIG. 1, FIG. 3 and FIG. 4 together, there are shown a partial side cross-sectional view and a schematic diagram for continuous operations according to the first preferred embodiment of the present invention. Firstly, as clearly seen from FIG. 1, the floating body 30 is located at the downmost location under the self-gravity, because the water level resulted from the waves 90 is not presented beneath the floating body 30 yet when the waves 90 are started to enter into the wave-guiding channel 20. Moreover, the toggle lever 60 is then turned downward under the self-gravity, and the toggle lever 60 is abutted against and supported by the abutting portion 32. When a large number of waves 90 are started to enter into the gully 24 of the wave-guiding channel 20, the waves 90 may be transmitted to the floating body 30 in a direction parallel to the gully 24 linearly, and converted into kinetic energy of upward motion of the floating body 30 effectively by the gully 24, as illustrated in FIG. 3. When the waves 90 reach the end portion 23, the advancing power of the waves 90 is limited by the end portion 23. Hence, there is nowhere for the collapse of the waves 90, which results in swiftly tiered and then risen level of water. At this time, kinetic energy of faster upward motion of the floating body 30 may be then generated, such that the toggle lever 60 may be pushed upward by the abutting portion 32 rapidly. Finally, when kinetic energy of forward motion of the waves 90 is exhausted completely, the waves 90 are retreated out of the gully 24 very fast, while the water level beneath the floating body 30 is also dropped very fast. In the meantime, the floating body 30 together with the toggle lever 60 are both dropped under the self-gravity back to the state illustrated in FIG. 1. Therefore, the object of electricity generation may be achieved, due to the fact that the toggle lever 60 may be pushed by the abutting portion 32 for driving the power generator 50, on the basis of difference in undulating level of water, converted from kinetic energy of the waves 90, by the use of the driving structure using kinetic energy of wave 10 of the present invention. Similarly, in the case that the ratchet wheel 70 or one-way bearing between the toggle lever 60 and the power generator 50 is inversely provided, the object of electricity generation by virtue of driving the power generator 50 to operate may be also achieved by means of hooking and pulling the toggle lever 60 by the abutting portion 32.

(8) Additionally, referring to FIG. 5, there is shown a top plane view according to a second preferred embodiment of the present invention. As clearly seen from the figures, the difference in the features of the second preferred embodiment in comparison with those of the first preferred embodiment is that the intake 25 of the second preferred embodiment is tapered, with reference to the spacing between the two side walls 22, in the shape of arc from the outside of the intake 25 toward the interior of the intake 25, so as to facilitate the reception of a larger number of waves 90 into the gully 24 initially. Then, much smoothness and more kinetic energy are produced. Moreover, greater difference in water level is achieved.

(9) As known from the above, it is clear from the technical solution of the present invention that the wave-guiding channel 20 is provided along the coastal land 80 and recessed into land in the present invention. Thus, the irregular waves 90 may be converted into usable kinetic energy effectively when the waves 90 are guided into the gully 24 by the wave-guiding channel 20 facing toward the ocean. Moreover, only forward and backward waves 90 are allowed, because the waves 90 are constrained by the gully 24. Thus, the floating body 30 is not pressed by side turbulent flow without the problem of consumption of kinetic energy due to lateral sway. Moreover, the object of swiftly floating the floating body 30 is also achieved, due to the fact that there is nowhere for the collapse of the waves eventually as well as the water level is tiered and then risen swiftly because of the constraint resulted from the end portion 23 of the gully 24. In addition, the problem of contacting with seawater does not occur on the pivot 40, because the floating body 30 is extended to pivotally connect with the pivot 40, which is provided on the top of the two side walls 22 of the gully 24 to be rigid and far away from the highest water level of the waves. Moreover, the floating body 30 and pivot 40 are neither liable to be corroded by seawater, nor liable to be damaged by severe upward and downward movement of water level of the waves 90, with both easier construction and maintenance, because connections of gears or bolts are neither presented in the floating body 30 nor in the pivot 40. Furthermore, the floating body 30 is extendingly provided at the other end thereof with the abutting portion 32, which is rigid as well as capable of pushing and then driving the power generator 50 to generate electricity. The abutting portion 32 is also not liable to drag and the resulting damage caused by severe upward and downward movement of water level of the waves 90 or slight deviation of the floating body 30, with easier construction and maintenance, because connections of gears or bolts are similarly not presented in the abutting portion 32. A fixed direction of the waves, with which the floating body 30 is contacted, may be assured, because the floating body is provided, in the wave-guiding channel 20, near the end portion 23. Moreover, the structure of the power generator 50 is also not connected with the floating body 30 by means of gears or bolts. Thus, it is truly possible to increase the volume of the floating body 30 (or the occupied surface area of land in the region of the floating body 30) in the present invention, in such a way that greater buoyant force is exerted on the floating body 30 for obtaining greater efficiency of kinetic energy conversion, and then achieving greater economic effectiveness of the power generator 50.
