[0046] The preferred embodiments of the utility model are described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model, and are not intended to limit the protection scope of the utility model. For example, although the following embodiments are introduced in combination with the wave power generation device, the wave power generation device provided by the utility model is also applicable to other products which need to solve the problem of complex structure of the device for generating power by using waves.

[0047] It should be noted that in the description of the utility model, unless otherwise explicitly specified and limited, the terms "arrangement", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0048] Based on the problems of the existing wave power generation device structure being complex and maintenance cost being high indicated by the background art, the utility model provides a wave power generation device, which aims to simplify the structure of the wave power generation device, so as to effectively solve the problems of the existing wave power generation device structure being complex and maintenance cost being high.

[0049] As shown in Figures 1 to 7 The utility model provides a wave power generation device, which comprises a support 1, a floating body 2 and a transmission assembly 3 and a power generation assembly 4 installed on the support 1.

[0050] As shown in Figure 3 The transmission assembly 3 comprises a driving mechanism 31, a lever mechanism 32 and a gear set 33, the driving mechanism 31 is connected with the floating body 2 and the lever mechanism 32 respectively, the floating body 2 can drive the driving mechanism 31 to move up and down, and the lever mechanism 32 can drive the gear set 33 to rotate under the driving of the driving mechanism 31.

[0051] As shown in Figure 7 And Figure 8 The power generation assembly 4 comprises a shell 41, a coil 42 arranged in the shell 41 and a magnet 43 corresponding to the coil 42, the magnet 43 is connected with the gear set 33, and the gear set 33 can drive the magnet 43 to rotate.

[0052] The support 1 is fixed at a proper position under the water surface and serves to support the floating body 2, the transmission assembly 3 and the power generation assembly 4, so as to ensure the stability and position fixation of them in the water. Exemplarily, the support 1 of the utility model is made of a corrosion-resistant material, such as stainless steel, high-strength alloy steel, titanium alloy and the like, so that the corrosion resistance and service life of the support 1 can be significantly improved.

[0053] The floating body 2 is a component capable of floating up and down with waves, so as to effectively capture the energy of waves and transmit the energy to the driving mechanism 31.

[0054] Preferably, the shape of the floating body 2 of the utility model is spherical, and the floating body 2 is hollow inside.

[0055] The spherical shape has the best hydrodynamic performance, can float more smoothly in waves, reduces frictional resistance with water, and thus improves energy conversion efficiency. Secondly, the spherical structure has the same strength and stability in all directions, can withstand wave impact from all directions, and ensures long-term durability of the float 2.

[0056] The interior of the float 2 is designed as a hollow structure, which greatly reduces the weight of the float 2, making it easier to be pushed by waves, thus improving the response speed and energy conversion efficiency of the entire wave power generation device. Secondly, the hollow structure provides additional buoyancy for the float 2, allowing it to float stably in deeper water without sinking due to water pressure. Finally, the hollow structure can also serve as a space for storing air or other lightweight gases, further increasing the stability and buoyancy of the float 2.

[0057] Further, as shown in Figure 1 and Figure 2 , the float 2 of the utility model can also be in the shape of a shell, and the interior of the float 2 is hollow. The shell-shaped float 2 has a streamlined shape, which can more effectively reduce the impact force and resistance of waves, making the movement of the float 2 in the waves more stable and efficient. This design helps to maximize the capture of wave energy and convert it into electrical energy. In addition, the shell-shaped float 2 not only has practical functions, but also has certain aesthetic appearance. Its unique shape and streamlined design make the entire wave power generation device more visually appealing, helping to improve the overall beauty and environmental friendliness of the marine environment.

[0058] The transmission assembly 3 is responsible for converting the up-and-down movement of the float 2 into rotational motion, and then driving the power generation assembly 4 to generate electricity. The transmission assembly 3 includes a drive mechanism 31, a lever mechanism 32, and a gear set 33. Among them, the drive mechanism 31 is connected with the float 2 and the lever mechanism 32, and can convert the up-and-down movement of the float 2 into the movement of the lever mechanism 32. The lever mechanism 32 uses the principle of leverage to convert the linear motion of the drive mechanism 31 into rotational motion, and then drives the gear set 33. The gear set 33 amplifies or decelerates the rotational motion of the lever mechanism 32 through the meshing of gears, to match the speed requirement of the power generation assembly 4.

[0059] The power generation assembly 4 can convert the mechanical energy transmitted by the transmission assembly 3 into electrical energy. The power generation assembly 4 includes a housing 41, a coil 42, and a magnet 43. Among them, the housing 41 is used to protect the internal elements from external environmental interference. The coil 42 is arranged in the housing 41, and when the magnet 43 rotates in the coil 42, according to Faraday's law of electromagnetic induction, an induced current will be generated in the coil 42. The magnet 43 is connected with the gear set 33, and the rotational motion of the gear set 33 drives the magnet 43 to rotate, thereby generating electrical energy in the coil 42.

[0060] When the wave acts on the floating body 2, the floating body 2 will float up and down with the wave. The up and down movement of the floating body 2 is transmitted to the lever mechanism 32 through the driving mechanism 31, and the lever mechanism 32 converts the linear motion into rotary motion by the principle of lever. Then, the rotary motion is further amplified through the gear set 33, and finally drives the magnet 43 connected with the gear set 33 to rotate. When the magnet 43 rotates in the coil 42, according to the principle of electromagnetic induction, an induced current will be generated in the coil 42, thereby realizing the conversion of wave energy into electric energy. Therefore, the wave energy can be efficiently captured and utilized through the cooperation of the floating body 2, the driving mechanism 31, the lever mechanism 32 and the gear set 33. The whole device has compact structure, small floor area, is convenient to install and maintain, can be applied to various sea areas and wave conditions, has strong environmental adaptability and stability.

[0061] Preferably, as shown in Figure 2 、 Figure 3 and Figure 5 , the bracket 1 is provided with a first perforation 11, the driving mechanism 31 comprises a driving rod 311, a first connecting piece 312 and a rotating shaft 313 rotatably arranged in the first connecting piece 312, the driving rod 311 is vertically arranged in the first perforation 11, the floating body 2 is arranged at the bottom end of the driving rod 311, the first connecting piece 312 is arranged at the top end of the driving rod 311, and the lever mechanism 32 is connected with the rotating shaft 313.

[0062] The bracket 1 of the utility model serves as the basis of the whole device, and in addition to providing stable support, is also designed with the first perforation 11, and the position and size of the first perforation 11 are carefully calculated and matched with the driving rod 311, thereby ensuring that the driving rod 311 can smoothly penetrate and freely move in the vertical direction.

[0063] The driving mechanism 31 mainly consists of a driving rod 311, a first connecting piece 312 and a rotating shaft 313. The driving rod 311 is vertically arranged in the first through hole 11, and the bottom end is connected with the floating body 2, and the top end is connected with the first connecting piece 312. In this way, when the floating body 2 moves up and down with the wave, the driving rod 311 also moves up and down, thereby driving the whole driving mechanism 31 to work. The first connecting piece 312 is arranged at the top end of the driving rod 311, and plays a connecting and supporting role. The design of the first connecting piece 312 enables the driving rod 311 to be stably connected therewith, and enables the up and down movement of the driving rod 311 to be converted into the rotating movement of the rotating shaft 313. The rotating shaft 313 is rotatably arranged in the first connecting piece 312, and is the connecting point between the driving mechanism 31 and the lever mechanism 32. When the driving rod 311 moves up and down, the rotating shaft 313 starts to rotate through the conversion of the first connecting piece 312, thereby driving the lever mechanism 32 to work. The lever mechanism 32 is connected with the rotating shaft 313, and when the rotating shaft 313 rotates, the lever mechanism 32 moves and generates a certain lever effect. The lever effect can further amplify the mechanical energy generated by the driving mechanism 31, and transmit it to the subsequent gear set 33.

[0064] By arranging the driving mechanism 31 in the above structure, not only the transmission efficiency of the wave power generation device is improved, but also the structure of the whole device is more compact and stable, and the whole device can still work stably and efficiently in the complex marine environment.

[0065] Preferably, as shown in Figure 2 、 Figure 3 and Figure 6 , the bracket 1 is further provided with a second through hole 12, the lever mechanism 32 comprises a mounting seat 321, a first lever 322 and a second lever 323, the rotating block 324 is rotatably arranged on the mounting seat 321, the first lever 322 is arranged in the rotating block 324, the second lever 323 is vertically arranged in the second through hole 12, the second connecting piece 325 is arranged at the bottom end of the second lever 323, the bearing block 326 is rotatably arranged in the second connecting piece 325, one end of the first lever 322 is slidably connected with the rotating shaft 313, the other end is slidably connected with the bearing block 326, and the top end of the second lever 323 is connected with the gear set 33.

[0066] The bracket 1 of the utility model is further provided with a first through hole 11, and the position and size of the second through hole 12 are configured to be matched with the second lever 323, so that the second lever 323 can be smoothly arranged and vertically moved freely.

[0067] The lever mechanism 32 mainly consists of three parts, a mounting seat 321, a first lever 322 and a second lever 323. Among them, the mounting seat 321 is fixed on the support 1, used for installing a rotating block 324. The rotating block 324 can freely rotate on the mounting seat 321, providing a flexible connection point for the first lever 322. The first lever 322 is provided in the rotating block 324, one end of which is in sliding connection with the rotating shaft 313, and the other end is in sliding connection with the bearing block 326. This sliding connection allows the first lever 322 to rotate and translate along a certain trajectory at the same time, thereby achieving a more complex transmission effect. The second lever 323 is provided in the second through hole 12 of the support 1 along the vertical direction, and the bottom end is provided with a second connecting piece 325. The second connecting piece 325 is rotatably provided with a bearing block 326, which is in sliding connection with the other end of the first lever 322. When the first lever 322 rotates and translates, it drives the second lever 323 to move up and down through the bearing block 326.

[0068] When the floating body 2 moves up and down with the waves, the driving rod 311 drives the rotating shaft 313 to rotate. When the rotating shaft 313 rotates, one end of the first lever 322 will rotate, and through the sliding connection with the rotating shaft 313 and the sliding connection with the bearing block 326, it will drive the first lever 322 to translate. This combination of rotation and translation will be transmitted to the second lever 323 through the bearing block 326, causing the second lever 323 to move up and down along the vertical direction. Finally, the top end of the second lever 323 will be connected with the gear set 33 to transmit mechanical energy to the power generation assembly 4. Thus, not only the transmission efficiency of the wave power generation device is improved, but also the stability and reliability of the entire system are enhanced, so that the entire device can better adapt to complex marine environments and maintain high efficiency and stable power generation performance under various wave conditions.

[0069] Preferably, as shown in Figure 2 、 Figure 3 and Figure 7 , the gear set 33 includes a rack 331 and a first gear 332 engaged with the rack 331, the rack 331 is fixedly arranged at the top end of the second lever 323, the first gear 332 is connected with the magnet 43, and the second lever 323 can drive the rack 331 to move up and down to drive the first gear 332 to rotate.

[0070] The rack 331 is fixedly arranged at the top end of the second lever 323, so that when the second lever 323 moves up and down, the rack 331 also moves up and down. Exemplarily, the rack 331 is covered with evenly distributed teeth for engaging with the first gear 332.

[0071] The first gear 332 is fixedly connected with the magnet 43. Thus, when the first gear 332 rotates, the magnet 43 also rotates. Exemplarily, the number of teeth of the first gear 332 matches the pitch of the rack 331, so as to ensure that the first gear 332 and the rack 331 can smoothly mesh and transmit power.

[0072] When the floating body 2 rises and falls with the waves, it drives the second lever 323 to move up and down through the driving mechanism 31 and the lever mechanism 32. Since the rack 331 is fixedly arranged at the top end of the second lever 323, when the second lever 323 moves up and down, the rack 331 also moves up and down. When the rack 331 moves up and down, it meshes with the first gear 332. Since the number of teeth and the pitch of the rack 331 and the first gear 332 match, the movement of the rack 331 drives the first gear 332 to rotate. Since the first gear 332 is connected with the magnet 43, more specifically, the first gear 332 is fixedly connected with the second fixed plate 412, when the first gear 332 rotates, the magnet 43 also rotates. The rotation of the magnet 43 generates electromagnetic induction in the coil 42 of the power generation assembly 4, thereby generating electric energy.

[0073] Through the meshing of the rack 331 and the first gear 332, the up-and-down movement of the second lever 323 is effectively converted into the rotational movement of the magnet 43, thereby improving the transmission efficiency of the entire wave power generation device. The design of the rack 331 and the first gear 332 makes the structure of the gear set 33 more compact, reduces the floor area and weight, and is beneficial to the installation and maintenance of the device.

[0074] Preferably, as shown in Figure 3 and Figure 7 The gear set 33 further includes a transmission gear, the bracket 1 is provided with a fixed seat 13, both ends of the transmission gear are rotatably connected with the fixed seat 13 and the housing 41, the transmission gear includes a second gear 333 and a third gear 334, the second gear 333 is coaxially and fixedly connected with the third gear 334, the second gear 333 meshes with the rack 331, the third gear 334 meshes with the first gear 332, and the diameter of the third gear 334 is greater than that of the first gear 332.

[0075] The bracket 1 is provided with a fixing seat 13 for supporting and fixing one end of the transmission gear. Thus, the transmission gear can rotate freely between the fixing seat 13 and the shell 41. The transmission gear comprises a second gear 333 and a third gear 334 which are coaxially fixedly connected together. Thus, when the second gear 333 rotates, the third gear 334 will also rotate synchronously. The second gear 333 is engaged with the rack 331. When the rack 331 moves up and down, it will drive the second gear 333 to rotate. The third gear 334 is engaged with the first gear 332, and when the third gear 334 rotates, it will drive the first gear 332 engaged therewith to rotate. Since the first gear 332 is fixedly connected with the magnet 43, when the first gear 332 rotates, the magnet 43 will also rotate. The rotation of the magnet 43 will generate electromagnetic induction in the coil 42 of the power generation assembly 4, thereby generating electric energy.

[0076] Further, since the diameter of the third gear 334 is greater than that of the first gear 332, according to the principle of gear transmission, the rotation speed of the first gear 332 will be increased, and the increase in the rotation speed of the first gear 332 means that the magnet 43 connected therewith will also rotate at a faster speed. In the power generation assembly 4, the rotation of the magnet 43 will generate electromagnetic induction in the coil 42, thereby generating electric energy, and the change of magnetic flux is the key to electromagnetic induction. When the magnet 43 rotates at a faster speed, it will cut the magnetic induction lines in the coil 42 faster, thereby causing the magnetic flux in the coil 42 to change more frequently. This more frequent change will generate a greater induced electromotive force in the coil 42, thereby generating more electric energy, further improving the power generation efficiency of the entire wave power generation device.

[0077] Preferably, as shown in Figure 8 and Figure 9 , the shell 41 is provided with a first fixed plate 411 and a second fixed plate 412, the first fixed plate 411 and the second fixed plate 412 are oppositely arranged, the coil 42 is provided with a plurality of coils 42, the plurality of coils 42 are circumferentially arranged on the first fixed plate 411, the magnet 43 is provided with a plurality of magnets 43, the plurality of magnets 43 are oppositely arranged with the plurality of coils 42 on the second fixed plate 412, and the first gear 332 is fixedly connected with the second fixed plate 412.

[0078] The first fixed plate 411 and the second fixed plate 412 are oppositely arranged to form a stable support structure for fixing the coil 42 and the magnet 43.

[0079] The coil 42 is provided with a plurality of coils 42, which are uniformly arranged circumferentially on the first fixed plate 411. This arrangement can ensure that the magnet 43 can uniformly cut the magnetic induction lines of the coil 42 when rotating, thereby generating a stable induced current.

[0080] Corresponding to the coils 42, multiple magnets 43 are also provided, and these magnets 43 are disposed on the second fixed plate 412 opposite to the multiple coils 42. The number and arrangement of the magnets 43 are matched with the coils 42 to ensure that their interaction achieves optimal effect, thereby improving energy conversion efficiency. Exemplarily, the magnets 43 can be fixed to the second fixed plate 412 by gluing, bolting, or other means to ensure their stability and positional fixation during rotation.

[0081] The first gear 332 is fixedly connected to the second fixed plate 412. This connection method ensures that when the first gear 332 rotates, it can drive the second fixed plate 412 and the magnet 43 on it to rotate together, thereby realizing the relative movement between the magnet 43 and the coil 42.

[0082] Preferably, such as Figure 9 As shown, magnet 43 is a magnet, and multiple magnets are configured such that the magnetic poles on the side facing coil 42 are arranged alternately with the south and north poles.

[0083] Multiple magnets are arranged on the side facing the coil 42, with their magnetic poles alternating between south (S) and north (N) poles. This configuration ensures that the magnets periodically change the direction of the magnetic field during rotation, thereby generating an alternating induced current in the coil 42. Furthermore, the alternating arrangement of the magnetic poles ensures that the magnets can more effectively cut the magnetic field lines of the coil 42 during rotation, resulting in a stronger induced current and contributing to improved energy conversion efficiency of the wave power generation device.

[0084] Preferably, such as Figure 3 As shown, a first limiting member 111 adapted to the drive rod 311 is provided in the first through hole 11. The drive rod 311 passes through the first limiting member 111 and slides in contact with the first limiting member 111.

[0085] The first limiting member 111 is adapted to the drive rod 311 to ensure that the drive rod 311 can smoothly enter and slide within it. This design not only restricts the movement trajectory of the drive rod 311, but also prevents the drive rod 311 from wobbling or deviating during movement, thereby ensuring the stability and reliability of the entire transmission system. Furthermore, a sliding contact is formed between the first limiting member 111 and the drive rod 311, thereby reducing the frictional resistance between them. This design helps to reduce energy loss during transmission and improve the power generation efficiency of the entire wave power generation device.

[0086] Preferably, such as Figure 3 As shown, a second limiting member 121 adapted to the second lever 323 is provided in the second through hole 12. The second lever 323 passes through the second limiting member 121 and slides in contact with the second limiting member 121.

[0087] Similarly, the second limiting member 121 is adapted to the second lever 323 to ensure that the second lever 323 can smoothly pass into and slide therein. This design not only limits the movement trajectory of the second lever 323, but also prevents the second lever 323 from shaking or deviating during movement, thereby further ensuring the stability and reliability of the entire transmission system. In addition, the second limiting member 121 and the second lever 323 form a sliding contact, thereby reducing the frictional resistance between the second limiting member 121 and the second lever 323. This design further reduces the loss of energy during transmission, further improving the power generation efficiency of the entire wave power generation device.

[0088] Preferably, the wave power generation device further comprises an electric energy conversion module (not shown in the figure) and an energy storage module (not shown in the figure), the electric energy conversion module is connected with the coil 42, and the energy storage module is connected with the electric energy conversion module.

[0089] The main function of the electric energy conversion module is to convert the induced electromotive force generated in the coil 42 into usable electric energy. In the wave power generation device, when the magnet 43 rotates with the fluctuation of the wave, it generates a changing magnetic flux in the coil 42, which in turn generates an induced electromotive force. The electric energy generated in this process is initially alternating current (AC) because the rotation of the magnet 43 causes the periodic change of the magnetic flux in the coil 42, thereby generating a sinusoidal waveform of alternating current. However, for many applications, direct current (DC) is more practical and convenient. Therefore, the electric energy conversion module is responsible for capturing these induced electromotive forces and converting them into stable direct current (DC) for subsequent use. The main function of the energy storage module is to store the electric energy generated by the electric energy conversion module and release it when needed.

[0090] By setting the electric energy conversion module and the energy storage module, the wave power generation device provided by the utility model can efficiently convert the induced electromotive force generated into usable electric energy and store it for later use. This greatly improves the utilization efficiency of energy, reduces energy waste, enhances the practicality and reliability of the wave power generation device, and makes it more suitable for various complex marine environments.

[0091] Preferably, the electric energy conversion module is a rectifier. The working principle of the rectifier is to use the unidirectional conductivity of semiconductor devices (such as diodes or transistors) to only allow one direction of alternating current to pass through, thereby preventing the flow of current in the other direction. In this way, the negative half cycle of alternating current is blocked, and the positive half cycle (or the negative half cycle after appropriate processing) is converted into direct current. Further, the rectifier of the utility model will also be equipped with a filter to smooth the pulsation in the direct current, thereby obtaining a more stable direct current output.

[0092] Preferably, the energy storage module is a supercapacitor.

[0093] Super capacitors can absorb and release a large amount of electrical energy in a short time, with very high power density. This makes them excellent in dealing with the rapid fluctuations of electrical energy in wave power generation devices. In addition, the charge and discharge cycle life of super capacitors is usually more than hundreds of thousands of times, much higher than that of batteries. This means that in the long-term operation of wave power generation devices, super capacitors can maintain stable performance and reduce maintenance costs. Further, the working temperature range of super capacitors is wide, and they can work normally in extreme environments. This is particularly important for wave power generation devices operating in harsh marine environments.

[0094] Exemplarily, as shown in Figure 8 The rectifier of the utility model is connected with the coil 42 by using a three-phase power system, and the coil 42 is connected with a phase difference of 120°, so that the currents of the three phases are staggered in time. Specifically, among the plurality of coils 42, every three adjacent coils 42 form a group, and among the coils 42 in the group, the first coil 42 is connected to the U phase (the first phase of the three-phase power supply) of the three-phase power supply, the second coil 42 is connected to the V phase (the second phase of the three-phase power supply) of the three-phase power supply, and the third coil 42 is connected to the W phase (the third phase of the three-phase power supply) of the three-phase power supply. In this way, alternating current can be efficiently and stably converted into direct current, and the transmission efficiency is higher.

[0095] Preferably, as shown in Figure 2 The support 1 comprises a bottom plate 14 and a top plate 15 which are arranged in a vertical direction, the bottom plate 14 is provided with a plurality of first legs 16 at the bottom, the top plate 15 is arranged at the top of the second legs 17.

[0096] The bottom plate 14 is provided with a plurality of first legs 16 at the bottom, which are used to increase the stability and supporting force of the bottom plate 14, so as to prevent the bottom plate 14 from shaking or moving under the action of waves. It should be noted that the number and arrangement of the first legs 16 can be customized according to actual needs to ensure the stability and supporting force of the bottom plate 14, and the utility model does not make specific limitations on the number and arrangement of the first legs 16.

[0097] The top plate 15 is provided with a plurality of second legs 17 at the top, which are also used to increase the stability and supporting force of the top plate 15. Unlike the first legs 16, the second legs 17 have a higher height to meet the installation requirements of the transmission assembly 3 and the power generation assembly 4 and other components. It should be noted that the number and arrangement of the second legs 17 also need to be customized according to actual needs, and the utility model does not make specific limitations.

[0098] The top plate 15 is located on top of the second support leg 17. With the support of the second support leg 17, the top plate 15 can maintain a stable horizontal position, providing a stable mounting platform for components such as the transmission assembly 3 and the power generation assembly 4.

[0099] Preferably, such as Figures 1 to 7 As shown, the transmission assembly 3 and the power generation assembly 4 are configured in two sets. The lever mechanism 32 of the first set of transmission assembly 3 is arranged on one side of the base plate 14 along the first direction, and the gear set 33 and the power generation assembly 4 are arranged on one side of the top plate 15 along the first direction. The second through hole 12 of the first set is opened on one side of the top plate 15. The lever mechanism 32 of the second set of transmission assembly 3 is arranged on the other side of the top plate 15 along the first direction, and the gear set 33 and the power generation assembly 4 are arranged on the other side of the base plate 14 along the first direction. The second through hole 12 of the second set is opened on the other side of the top plate 15.

[0100] By configuring two sets of transmission components 3 and power generation components 4, the wave power generation device can capture the energy of waves more comprehensively, thereby improving the overall power generation efficiency. Furthermore, by setting the first set of lever mechanisms 32 along the first direction on one side of the base plate 14, and the second set of gear sets 33 and power generation components 4 along the first direction on the other side of the base plate 14; and by setting the first set of gear sets 33 and power generation components 4 along the first direction on one side of the top plate 15, and the second set of lever mechanisms 32 along the first direction on the other side of the top plate 15, the force on the entire device under wave action is more uniform, which helps to enhance the stability and reliability of the device and maximize the use of space on the base plate 14 and top plate 15, reducing space occupation and mechanical interference between components, making the entire device more compact and efficient.

[0101] It should be noted that by setting two sets of transmission components 3 and power generation components 4, this utility model can ensure the power generation stability of the wave power generation device. Of course, in other embodiments, the transmission components 3 and power generation components 4 can also be three or four sets, etc. The specific number of transmission components 3 and power generation components 4 can be determined according to power generation needs, wave conditions, structural stability, etc. This utility model does not limit the specific number of transmission components 3 and power generation components 4.

[0102] It should be further noted that when three or four sets of transmission components 3 and power generation components 4 are set, the number of base plates 14 and top plates 15 can be increased according to the different number of sets, and adjacent transmission components 3 and power generation components 4 can be arranged in the above-mentioned installation method. This further maximizes the use of space on base plates 14 and top plates 15, reduces space occupation and mechanical interference between components, and makes the whole device more compact and efficient.

[0103] Preferably, such as Figure 2 and Figure 3As shown, the first perforation 11 of the first group is set on the bottom plate 14, the first perforation 11 of the second group is set on the top plate 15, and the first perforation 11 of the second group is located directly above the first perforation 11 of the first group. The float 2 is set below the bottom plate 14. The first connector 312 of the first group is set between the bottom plate 14 and the top plate 15. The bottom end of the drive rod 311 of the first group is connected to the float 2, and the top end is connected to the bottom of the first connector 312. The first connector 312 of the second group is set above the top plate 15. The bottom end of the drive rod 311 of the second group is connected to the top of the first connector 312 of the first group, and the other end is connected to the bottom of the first connector 312 of the second group.

[0104] When the waves push the float 2 up and down, the float 2 will drive the first set of drive rods 311 to move together. The first set of drive rods 311 transmits motion to the first set of lever mechanisms 32 through the first set of first connecting members 312, converting the linear motion of the first set of drive rods 311 into the rotational motion of the first set of lever mechanisms 32. At the same time, since the second set of drive rods 311 is connected to the first set of first connecting members 312, the second set of drive rods 311 will also move with the up and down movement of the first set of drive rods 311. Then, the second set of drive rods 311 transmits motion to the second set of lever mechanisms 32 through the second set of first connecting members 312, similarly converting the linear motion of the second set of first connecting members 312 into the rotational motion of the second set of lever mechanisms 32. In this way, the two sets of transmission components 3 can work simultaneously, converting more wave energy into electrical energy, improving power generation efficiency and stability.

[0105] Furthermore, the structure of the drive mechanism 31 has been further simplified, reducing the number and complexity of parts. This not only reduces manufacturing costs but also improves the reliability and stability of the drive mechanism 31. The first perforation 11 of the second group is located directly above the first perforation 11 of the first group, which allows the drive rods 311 of the first group and the drive rods 311 of the second group to be on the same vertical line. Thus, when the drive rods 311 of the first group rise with the rise of the float 2, the force is transmitted to the drive rods 311 of the second group through the first connector 312 of the first group more directly and efficiently, reducing additional friction and resistance, and effectively reducing energy loss during transmission. In addition, it makes the structure of the entire device more compact, thereby making more effective use of the space on the bottom plate 14 and the top plate 15, and reducing space occupation and mechanical interference between components.

[0107] A reinforcing rod 18 is arranged between two adjacent first legs 16. The reinforcing rod 18 serves to improve the overall rigidity and stability of the support 1, preventing the support 1 from deforming or being damaged when subjected to wave impact or other external forces. By firmly connecting the reinforcing rod 18 to the first leg 16 through the first reinforcing member 161, it can be ensured that the reinforcing rod 18 can effectively transmit and disperse the force received by the support 1, thereby improving the overall stability of the support 1. Thus, even if the support 1 is subjected to a larger external force, it can maintain the stability of its shape and position, thereby ensuring the normal operation and safety of the wave power generation device.

[0111] Exemplarily, the second reinforcing member 172 can be a bolt, a welded joint, a rivet or other types of connecting members, and the material and form of the second reinforcing member 172 are not specifically limited in the present application.

[0113] The bottom end of the second leg 17 is connected to the bottom plate 14 through the third reinforcing member 171. This design ensures the firm connection between the second leg 17 and the bottom plate 14, further improving the overall stability and load-carrying capacity of the support 1.

[0116] ​​​The top end of the second leg 17 is connected with the top plate 15 through a fourth reinforcing piece 172. This design not only ensures the firm connection between the second leg 17 and the top plate 15, but also further enhances the overall rigidity and stability of the bracket 1.

[0117] Exemplarily, the fourth reinforcing piece 172 can be a bolt, a welded joint, a rivet or other types of connecting pieces, and the material and form of the fourth reinforcing piece 172 are not specifically limited in the present application.
