Description

Technical Field

[0001] This utility model relates to the field of wave energy power generation technology, specifically to a wave energy conversion device. Background Technology

[0002] With the continuous growth of global energy demand and the increasing severity of environmental problems, the development and utilization of renewable energy has become a global focus. Ocean wave energy, as a clean and sustainable energy form, has enormous development potential. Currently, there are various technological approaches to wave energy power generation, among which buoy-based wave energy power generation technology is one of the key areas of research and application. Float-based power generation devices typically use the rising and falling motion of a buoy on the water surface to drive the power generation mechanism, thereby achieving energy conversion. These devices utilize the buoyancy changes generated by the up-and-down movement of waves, converting the buoy's motion into electrical energy through a mechanical structure.

[0003] The prior art disclosed in CN118705106A is a dual-buoy wave energy conversion device, which includes a float link holder with two end faces that are connected through each other. A float link is arranged inside the float link holder. A float one and a float two are arranged on the float link and extend downwards. The float one and the float two are respectively located on both sides of the float link holder. A connecting seat is installed on one side of the upper end of the float link. A transmission rack is rotatably connected to the connecting seat. The transmission rack is meshed with a gear set. The gear set is arranged on a mounting seat. The mounting seat is fixedly installed on the float link holder. The float one and the float two alternately rise and fall under the action of waves, which drives the transmission rack to make linear reciprocating motion relative to the gear set. The gear set converts the linear reciprocating motion of the transmission rack into unidirectional periodic rotational motion.

[0004] However, the existing wave energy conversion device still has shortcomings. For example, it can only convert the mechanical energy of the float moving in the vertical plane into electrical energy. The movement of the float in the horizontal plane is limited, and the movement in the horizontal plane can not be converted into electrical energy, thus limiting the power generation efficiency. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a wave energy conversion device to solve the technical problem that existing wave energy conversion devices can only convert the mechanical energy of the float moving in the vertical plane into electrical energy, while the movement of the float in the horizontal plane is limited and cannot be converted into electrical energy, thus limiting the power generation efficiency.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a wave energy conversion device, comprising:

[0008] The conversion assembly includes a fixed housing, a first receiving member, and a second receiving member. The first receiving member is used to connect to a generator and is slidably connected to the fixed housing along a first direction. The second receiving member is used to connect to the generator and is slidably connected to the fixed housing along a second direction. The first direction and the second direction are arranged at an angle.

[0009] A motion component includes a connected motion element and a float. The motion element is capable of abutting against the first receiver and the second receiver. When in motion, the float is capable of driving the motion element to move, so that the motion element pushes the first receiver to slide in a first direction or pushes the second receiver to slide in a second direction.

[0010] In some embodiments, the first direction and the second direction are perpendicular to each other.

[0011] In some embodiments, the number of the first receivers is two, and the two first receivers are respectively movably connected to opposite sides of the moving member along the first direction.

[0012] In some embodiments, the number of the second receivers is two, and the two second receivers are respectively movably connected to opposite sides of the moving member along the second direction.

[0013] In some embodiments, the moving component has a main slide groove, the first receiving component has a first slide groove, and the moving component further includes a connecting component, the two ends of which are slidably engaged with the main slide groove and the first slide groove, respectively.

[0014] In some embodiments, the connector includes a first ball, a connecting rod, and a second ball connected in sequence, wherein the first ball is engaged in the main slide groove, and the second ball is engaged in the first slide groove.

[0015] In some embodiments, the conversion assembly further includes a first reset spring and a second reset spring, wherein the first reset spring is connected to the fixed housing and the first receiving member, and the second reset spring is connected to the fixed housing and the second receiving member.

[0016] In some embodiments, the conversion component further includes a third receiver connected to the end of the moving member away from the float, the moving member being capable of driving the third receiver to reciprocate along a third direction, the third direction being perpendicular to the first direction and the second direction.

[0017] In some embodiments, the motion component further includes a guide shell, the guide shell having a plurality of positioning grooves around the third-direction periphery, the motion component having a plurality of positioning posts around the third-direction periphery, the motion component being slidably inserted into the guide shell, and the plurality of positioning posts correspondingly slidingly engaging with the plurality of positioning grooves.

[0018] In some embodiments, a third return spring is provided inside the guide housing, and the third return spring is connected to the moving part.

[0019] Compared with existing technologies, the wave energy conversion device provided by this utility model has a float that can be placed on the water surface. The undulating waves propel the float, which in turn drives a moving component in multiple directions. This moving component then drives a first and a second receiving component. Both the first and second receiving components can be connected to a generator, enabling the conversion of mechanical energy into electrical energy to power the generator during their movement. Because the sliding direction of the first and second receiving components is at an angle to each other, the moving component can drive both the first and second receiving components to slide in both the horizontal and vertical directions, thus enabling the generator to generate electricity. This results in high power generation efficiency and high energy utilization. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] To address the technical problem that existing wave energy conversion devices can only convert the mechanical energy of a float moving in a vertical plane into electrical energy, while the float's movement in the horizontal plane is restricted and essentially cannot be converted into electrical energy, thus limiting power generation efficiency, this invention provides a wave energy conversion device that can convert mechanical energy into electrical energy when the float moves in any direction, with unrestricted movement, high power generation efficiency, and high energy utilization rate.

[0026] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the wave energy conversion device in one embodiment of the present invention. The wave energy conversion device includes a conversion component 1 and a motion component 2. The conversion component 1 includes a fixed shell 11, a first receiving member 12 and a second receiving member 13. The first receiving member 12 is slidably connected to the fixed shell 11 along a first direction, and the second receiving member 13 is slidably connected to the fixed shell 11 along a second direction. The first direction and the second direction are set at an angle. The angle is not limited and can be greater than 0° and less than 180°. In a preferred embodiment, the first direction and the second direction are perpendicular to each other so that the motion component 2 can fully convert mechanical energy into electrical energy when it moves.

[0027] The motion assembly 2 includes a moving component 21, a float 22, and a crank 23 connected together. The two ends of the crank 23 are connected to the moving component 21 and the float 22, respectively. The moving component 21 is located between the first receiver 12 and the second receiver 13, and is capable of driving the first receiver 12 and the second receiver 13 to slide during motion. The moving component 21 can be... Figure 2 In the illustrated embodiment, the prism component has two faces of the moving member 21 facing the first receiver 12 and the second receiver 13, respectively. When the moving member 21 moves under the traction of the float 22, one face of the moving member 21 can press against the first receiver 12 and drive the first receiver 12 to slide, while the other face of the moving member 21 can press against the second receiver 13 and drive the second receiver 13 to slide. In other embodiments, the moving member 21 can also be cylindrical to make its movement between the first receiver 12 and the second receiver 13 smoother.

[0028] The fixed shell 11 includes a shell 111, a first frame 112, and a second frame 113 connected in sequence. The connection method is not limited and can be achieved by screws or welding. The first frame 112 and the second frame 113 are perpendicular to each other, meaning that the first frame 112 can be aligned with the second frame 113 by rotating 90°. The first frame 112 is slidably connected to the first receiving member 12, and the second frame 113 is slidably connected to the second receiving member 13. Since the first frame 112 and the second frame 113 are perpendicularly arranged, the first receiving member 12 and the second receiving member 13 are also perpendicularly arranged to receive the forces exerted by the moving member 21 in the horizontal and vertical directions.

[0029] The housing 111 can be fixedly installed on the shore 3. The float 22 is placed on the water surface. When waves generated on the water surface act on the float 22, they will push the float 22 to move. The float 22 drives the moving component 21 to move, so that the moving component 21 pushes the first receiver 12 to slide along a first direction, or pushes the second receiver 13 to slide along a second direction. Both the first receiver 12 and the second receiver 13 can be connected to a generator, so that the first receiver 12 and the second receiver 13 can convert mechanical energy into electrical energy for the generator to generate electricity. Since the sliding direction of the first receiver 12 and the sliding direction of the second receiver 13 are set at an angle, when the float 22 drives the moving component 21 to move in the horizontal or vertical direction, the moving component 21 can drive the first receiver 12 and the second receiver 13 to slide, so as to convert mechanical energy into electrical energy, which helps to improve the power generation efficiency of the generator and fully utilize wave energy.

[0030] Please see Figure 2 and Figure 3 Both the first receiving member 12 and the second receiving member 13 are T-shaped. The first receiving member 12 includes a slide rod 121 and a push plate 122, with the slide rod 121 and the push plate 122 connected perpendicularly. The first frame 112 has a through-hole 113 and a sliding groove 114. The slide rod 121 slides through the through-hole 113, and the push plate 122 slides in the sliding groove 114, so that the first receiving member 12 can reciprocate stably along the first direction. The structure of the second receiving member 13 is the same as that of the first receiving member 12, and its connection with the fixed shell 11 is not described in detail here.

[0031] The connection method between the first receiver 12, the second receiver 13, and the generator is not limited. In one embodiment, they can be connected by meshing. Specifically, the slide rod 121 of the first receiver 12 has teeth, and the generator gear 3 is connected to the generator gear 3 through the teeth. During the reciprocating sliding process, the first receiver 12 and the second receiver 13 can drive the generator gear 3 to rotate through meshing. When the generator gear 3 rotates, it can generate electricity for the generator. The second receiver 13 has the same structure as the first receiver 12 and the same connection method with the generator, which will not be described in detail here.

[0032] In one embodiment, please refer to Figure 3 There are two first receiving elements 12, which are movably connected to opposite sides of the moving element 21 along the first direction. In this embodiment, when the moving element 21 reciprocates along the first direction under the drive of the float 22, the moving element 21 can simultaneously drive the two first receiving elements 12 to slide back and forth, so that the two first receiving elements 12 generate electricity for the generators connected to them respectively, generating electricity for two generators at once, which is beneficial to improving power generation efficiency.

[0033] In one embodiment, please refer to Figure 2 There are two second receivers 13, which are movably connected to opposite sides of the moving member 21 along the second direction. In this embodiment, when the moving member 21 reciprocates along the second direction under the drive of the float 22, the moving member 21 can simultaneously drive the two second receivers 13 to slide back and forth, so that the two second receivers 13 generate electricity for the generators connected to them respectively, generating electricity for two generators at once, which is beneficial to improving power generation efficiency.

[0034] In one embodiment, please refer to Figure 3 The moving component 21 has a main slide groove 211, and the first receiving component 12 has a first slide groove 123. The moving component 2 also includes a connecting component 23, whose two ends are slidably engaged with the main slide groove 211 and the first slide groove 123, respectively. In this embodiment, by slidably engaging the main slide groove 211 and the first slide groove 123 with the two ends of the connecting component 23, the moving component 21 and the first receiving component 12 are connected through the connecting component 23. During the reciprocating motion, the moving component 21 can drive the first receiving component 12 to slide back and forth, so that the first receiving component 12 can drive the generator to generate electricity during the reciprocating motion, which is beneficial to improving the generator's power generation efficiency. In this embodiment, the moving component 21 has a main slide groove 211 on all four sides of its periphery, and the connecting component 23 can be connected to any one of the main slide grooves 211, making it easy to assemble and disassemble.

[0035] In one embodiment, please refer to Figure 3 The connector 23 includes a first ball bearing 231, a connecting rod 233, and a second ball bearing 232 connected in sequence. The first ball bearing 231 is engaged in the main slide groove 211, and the second ball bearing 232 is engaged in the first slide groove 123. In this embodiment, the connector 23 engages the moving part 21 with the ball bearings, allowing the moving part 21 to move freely along its length, and making it quick and easy to assemble and disassemble the connector 23. In other embodiments, the connecting rod 233 can be replaced with a chain to allow for a certain space between the moving part 21 and the first receiving part 12, making it even easier to assemble and disassemble the connector 23.

[0036] In one embodiment, the conversion assembly 1 further includes a first return spring and a second return spring (not shown in the figure). The first return spring connects the first frame 112 and the first receiver 12, and the second return spring connects the second frame 113 and the second receiver 13. In this embodiment, when the moving member 21 pushes the first receiver 12 to slide, the first receiver 12 compresses the first return spring, causing the first return spring to accumulate elastic force. When the moving member 21 releases its force on the first receiver 12, the first return spring releases its elastic force, causing the first receiver 12 to slide back to its original position. During the reset process, the first receiver 12 can accumulate sliding force to drive the generator to generate electricity. In addition, the first receiver 12 can also slide back to its initial position so that the moving member 21 can contact the first receiver 12 earlier and push the first receiver 12 to slide in the next operation, which is beneficial to further improve the generator's power generation efficiency. Similarly, the second return spring has the same effect on the second receiver 13, which will not be described in detail here.

[0037] In one embodiment, please refer to Figure 4 The conversion component 1 also includes a third receiver 14, which is connected to the end of the moving member 21 away from the float 22. The moving member 21 can drive the third receiver 14 to reciprocate along a third direction when it reciprocates in that direction, which is perpendicular to the first and second directions. In this embodiment, the float 22 moves in multiple directions. When the float 22 drives the moving member 21 to move along a third direction, the moving member 21 can drive the third receiver 14 to reciprocate in that direction, so as to convert the mechanical energy of the third receiver 14 into electrical energy of the generator connected to the third receiver 14, thus fully converting the mechanical energy generated by the float 22 when subjected to waves. The third direction can be understood as the length extension direction of the moving member 21. A movement space is left between the first receiver 12 and the second receiver 13, through which the moving member 21 passes and connects to the third receiver 14.

[0038] In one embodiment, please refer to Figure 4The motion component 2 also includes a guide shell 24, which has multiple positioning grooves 241 around its axial direction, or multiple positioning grooves 241 around a third direction. The third receiving component 14 has multiple positioning posts 141 around the third direction. The motion component 21 is slidably inserted into the guide shell 24, and the multiple positioning posts 141 are correspondingly slidably engaged with the multiple positioning grooves 241. In this embodiment, the third receiving component 14 is slidably engaged with the multiple positioning grooves 241 of the guide shell 24 through the multiple positioning posts 141, so that the third receiving component 14 can maintain a stable sliding directional connection with the guide shell 24. The guide shell 24 remains fixed. When the motion component 21 moves along the third direction under the action of the float 22, the motion component 21 drives the third receiving component 14 to slide along the third direction. The third receiving component 14 has a rack 142, which meshes with the generator gear of the generator, so that when the third receiving component 14 drives the rack 142 to move, the rack 142 drives the generator gear to rotate through meshing, and the generator gear supplies power to the generator.

[0039] In one embodiment, please refer to Figure 4 A third return spring 242 is provided inside the guide housing 24, and the third return spring 242 is connected to the rack 142 of the third receiving member 14. In this embodiment, when the rack 142 of the third receiving member 14 moves toward the third return spring 242, the rack 142 can drive the third return spring 242 to accumulate elastic force. At the same time, the rack 142 can drive the generator gear to rotate through meshing, generating electricity for the generator. When the third receiving member 14 loses the force applied by the float 22 in a third direction, the third return spring 242 releases elastic force to drive the third receiving member 14 away from the third return spring 242 to slide and reset. During this process, the rack 142 will again drive the generator gear to rotate through meshing, generating electricity for the generator. Therefore, by providing the third return spring 242, this embodiment can further improve the power generation efficiency of the generator.

[0040] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0041] The wave energy conversion device provided by this utility model has a float 22 that can be placed on the water surface. The undulating waves propel the float 22, which in turn drives a moving component 21 to move in multiple directions. The moving component 21 then drives a first receiving component 12 and a second receiving component 13. Both the first and second receiving components 12 and 13 can be connected to a generator, allowing them to convert mechanical energy into electrical energy to power the generator during their movement. Because the sliding direction of the first receiving component 12 is angled to the sliding direction of the second receiving component 13, the moving component 21 can drive the first and second receiving components 12 and 13 to slide both horizontally and vertically, thus enabling the generator to generate electricity. This results in high power generation efficiency and high energy utilization. Furthermore, the float 22 can also drive the moving component 21 to reciprocate in a third direction, which in turn drives a third receiving component 14 to reciprocate in that direction, further improving power generation efficiency. Therefore, the float 22 of this invention can drive the moving part 21 to move in any direction under the action of waves, and convert the mechanical energy of the moving part 21 into the electrical energy of the generator, so that the energy conversion is sufficient.

[0042] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
