[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] As Figures 1-3 shown,Figure 1 A schematic diagram of the structure of the wave energy power generation device provided by the present invention; Figure 2 for Figure 1 Schematic diagram of the top structure of the medium wave energy power generation device; Figure 3 for Figure 1 An enlarged view of the partial structure of the floating power generation assembly in a medium wave energy power generation device.

[0036] This embodiment provides a wave energy power generation device, including a floating power generation assembly 1, and a slide rail guide device 2 for guiding the sinking and floating of the floating power generation assembly 1. The floating power generation assembly 1 floats in a wave environment such as the sea surface or the water surface, and the slide rail guide device 2 guides and supports the floating sinking and floating of the floating power generation assembly. The slide rail guide device 2 is usually fixed on a base 3, and the base 3 can be a building such as a levee, a buoy, a tower, etc. fixed on the seabed, the bottom of the water, or the shore.

[0037] The slide rail guiding device 2 comprises a first guide rail assembly 21, a second guide rail assembly 22, and a slide frame 23 connecting the first guide rail assembly 21 and the second guide rail assembly 22.

[0038] The first guide rail assembly 21 and the second guide rail assembly 22 are arranged alternately in the guide rail pressing direction, the floating power generation assembly 1 is fixed on the first guide rail assembly 21, and a power generation drive device cooperating with the floating power generation assembly is arranged on the first guide rail assembly 21.

[0039] When the wave energy power generation device is in a wave environment, the floating power generation assembly 1 sinks along the guide direction of the slide rail guide device 2, the slide rail guide device 2 is connected to the floating power generation assembly 1 by a slide 23, the slide 23 is connected to the first guide rail assembly 21 and the second guide rail assembly 22, the first guide rail assembly 21 and the second guide rail assembly 22 are staggered in the guide rail clamping direction, the floating power generation assembly 1 is fixed on the first guide rail assembly 21 and cooperates with it to generate electricity, the first guide rail assembly 21 and the second guide rail assembly 22 are staggered in the guide rail clamping direction, and the guide rail and the running wheel can be limited in the clamping direction to avoid the guide rail and the running wheel from falling out, thereby ensuring the walking stability of the running wheel and the guide rail.

[0040] In a specific embodiment of the present case, the first guide rail assembly 21 includes a first guide rail 212 and a first running wheel 211 that cooperates with the first guide rail 212, and the first guide rail 212 includes a running side 2121 and a rack side 2122. A driving wheel 11 that cooperates with the rack side in transmission extends from the floating power generation assembly 1. The first guide rail 212 is also a cylindrical guide rail, which is composed of a running side 2121 and a rack side 2122 to form a cylindrical rack structure to ensure the transmission cooperation structure with the driving wheel.

[0041] Furthermore, the second guide rail assembly 22 includes two symmetrically arranged on both sides of the first guide rail assembly 21. The second guide rail assembly 22 includes a second guide rail 222 and a second traveling wheel 221 that travels in cooperation with it; the traveling support directions of the first traveling wheel 221 and the second traveling wheel 222 are arranged in opposite directions.

[0042] The floating body power generation assembly 1 sinks and rises under the drive of waves. It is guided and restricted by the slide rail guiding device 2 and can only float up and down along the length direction of the guide rail. At the same time, the first guide rail assembly 21 and the second guide rail assembly 22 jointly bear the swinging force transmitted during the sinking and rising process of the floating body power generation assembly 1. To avoid the separation between the guide rail and the traveling wheel, the guide rail includes a first guide rail 212 and two second guide rails 222, and the three are arranged in parallel. The first traveling wheel 211 and the second traveling wheel 221 are arranged in a staggered structure.

[0043] As Figure 2 In the position layout diagram shown, the first traveling wheel 211 is located below the first guide rail 212, and the second traveling wheel 221 is located above the second guide rail 222. When the three traveling wheels swing, along the direction in which the traveling wheels press against the guide rail, it can always be ensured that at least one set of traveling wheels and the guide rail are pressed together to avoid separation.

[0044] Furthermore, the first traveling wheel 211 is located in the middle, and the two second traveling wheels 221 are located on both sides of the first traveling wheel 211. Then, when the floating body power generation assembly 1 swings towards the base, it is supported by the first traveling wheel 211 and the first guide rail 212 during traveling, and at the same time, the base provides support and limitation to ensure the support stability.

[0045] When the floating body power generation assembly 1 swings away from the base, the two second traveling wheels 221 and the second guide rail 222 ensure the traction balance of the floating body power generation assembly 1.

[0046] As Figure 4 And Figure 5 Shown, Figure 4 Is Figure 1 The schematic diagram of the installation structure of the guide rail support in the wave energy power generation device in Figure 5 Is Figure 2 The schematic diagram of the structure of the carriage in

[0047] Furthermore, it also includes a guide rail support 24. The guide rail support 24 includes a mounting plate connecting to the base,

[0048] Extending from both sides of the width direction of the mounting plate and respectively fixedly connecting the side mounting plates of the two second guide rails 222; a central support frame for supporting the first guide rail extends from the middle of the mounting plate.

[0049] A guide rail fixing support member 223 connecting to the second guide rail 222 is fixedly installed on the side mounting plate;

[0050] A rack fixed support 213 connected to the first guide rail 212 is fixedly installed on the middle support frame.

[0051] The first guide rail 212 and the two second guide rails 222 are both cylindrical guide rails. One side in the radial direction of the cylindrical guide rail is in walking cooperation with the walking wheels, and the other side is fixedly connected to the guide rail bracket, realizing the fixed connection between the guide rail and the guide rail bracket. By providing the guide rail fixed support 223 and the rack fixed support 213, the connecting end faces of the two with the guide rail are arc connecting faces, and the arc connecting face is a minor arc structure to avoid interference with the walking of the walking wheels.

[0052] In a specific embodiment of this case, the carriage 23 is a walking wheel mounting carriage prepared by bending a plate. The walking wheel mounting carriage includes a first mounting area 231 for mounting the first walking wheel 211 and a second mounting area 232 for mounting the second walking wheel 221.

[0053] Both the first walking wheel 211 and the second walking wheel 221 have multiple walking wheels walking in parallel.

[0054] The carriage 23 adopts a plate structure and is prepared into a bent structure by bending. In the guiding direction of the slide rail guiding device 2, which is the width direction of the plate structure of the carriage 23, the contact resistance between the carriage and the waves is minimized, improving the power generation capacity of the floating body power generation assembly 1.

[0055] The first mounting area 231 and the second mounting area 232 are formed by bending the carriage 23. The bent structure of the carriage 23 can be directly used to prepare the mounting bracket for the walking wheels, reducing the preparation difficulty of the carriage 23.

[0056] In a specific embodiment of this case, the floating body power generation assembly 1 includes a floating body shell 12 and a gearbox 13. The floating body shell 12 is fixedly installed in the first mounting area 231; a driving shaft 14 connected to the prime mover wheel 11 extends from the gearbox 13. Specifically, the floating body shell 12 is mostly a cylindrical structure. A floating body shell connecting plate 214 is fixedly installed on the plate surface of the first mounting area 231. The floating body shell connecting plate 214 is fixedly connected to the floating body shell 12 by an arc surface structure to ensure the connection structure stability of the floating body shell 12.

[0057] Furthermore, a limiting rod 25 for limiting the sliding end point of the carriage 23 is also connected between the two side mounting plates. The carriage 23 and the guide rail are guided by the rolling of the walking wheels. To prevent the carriage 23 from disengaging from the guide rail bracket 24, a limiting rod 25 passing through the two side connecting plates is provided on the guide rail bracket 24. At the same time, the limiting rod 25 passes through the middle support frame in the middle of the guide rail bracket 24. For example, Figure 2 in the figure, the limiting rod 25 is supported in the thickness direction by both ends and the middle of the guide rail bracket 24 to prevent the carriage 23 from disengaging due to the impact on the limiting rod 25 by the carriage 23.

[0058] In a specific embodiment of this case, the guide rail bracket includes two respectively arranged at both ends of the traveling direction of the slide rail guiding device.

[0059] The slide rail guiding device 2 includes a plurality of members that guide the settlement and floating of the floating body power generation assembly 1. The plurality of slide rail guiding devices 2 are spliced and matched. The limiting rod 25 includes two respectively arranged at both ends of the plurality of slide rail guiding devices 2.

[0060] The slide rail guiding device 2 adopts a splicable structure. For different wave intensities, a plurality of slide rail guiding devices 2 can be connected in series to extend the traveling distance of the floating body power generation assembly 1, so as to make full use of wave energy and improve its power generation capacity. For a plurality of slide rail guiding devices 2 with a series structure, the adjacent slide rail guiding devices 2 are still fixedly connected to the base body 3 through the guiding bracket 24. The limiting rod 25 is arranged at both ends in the length direction of the plurality of series-structured slide rail guiding devices 2 to ensure safe traveling.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
