[0004] During use, the power generation device is supported on the ground near the shore by supporting legs, which still has the following disadvantages: the power generation device is fixed in one place, and when the tide recedes, the power generation device cannot generate electricity, and the working time of the power generation follows the time of the tide, which may lead to limited power generation efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a wave power generation device to solve the problem that when the tide is low, the power generation device cannot work and generate electricity, and the working time of the power generation follows the time of the tide, which may lead to limited power generation efficiency.

[0006] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: a wave power generation device, comprising a floating board, a fixing frame is detachably provided on the top surface of the floating board, two support frames are fixed on the top surface of the fixing frame, a mounting plate is fixed on the top surface of the support frame, a connecting rod is fixed between the two support frames, a rotating tube is rotatably inserted on the connecting rod, an arc frame is fixed on the rotating tube, a rocker is fixed on the surface of the rotating tube, a pendulum is fixed on the bottom end of the rocker, a positioning plate is fixed on the top surface of the mounting plate, a fixing hole is opened on one side of the positioning plate, a bearing is fixed inside the fixing hole, a rotating shaft is fixed on the inner wall surface of the inner ring of the bearing, a sprocket is fixedly sleeved on the rotating shaft, a chain is fixed on the arc frame, the chain and the sprocket are meshed with each other, driving gears are fixedly sleeved on the surfaces of both ends of the rotating shaft, two generators are fixed on the top surface of the mounting plate, a driven gear is fixed on one end of the output shaft of the generator, and the driving gear and the driven gear are meshed with each other.

[0007] Preferably, a hemispherical plate is fixed to the bottom surface of the floating board, a battery is arranged inside the hemispherical plate, a PLC controller is arranged on the top surface of the floating board, the battery is electrically connected to the PLC controller, and the generator is electrically connected to the PLC controller.

[0008] Preferably, a wire is fixedly sleeved on the hemispherical plate, one end of the wire is fixed to the battery, and a counterweight is slidably inserted on the wire.

[0009] Preferably, a threaded tube is fixedly mounted on the conductor, and a blocking ring is threadedly connected to the threaded tube.

[0010] Preferably, a protective cover is fixed to the top surface of the floating board, an indicator light is fixed to the top of the protective cover, and the indicator light is electrically connected to the PLC controller.

[0011] Preferably, two traction ropes are fixed on the protective cover, a fixing ring is fixed to the other end of the traction rope, a limiting column is slidably inserted inside the fixing ring, and a blocking plate is fixed to the top of the limiting column.

[0012] Preferably, the top surface of the fixing frame is provided with a plurality of positioning holes, the top surface of the floating board is provided with a plurality of threaded grooves, fixing bolts are rotatably inserted inside the positioning holes, and the bottom ends of the fixing bolts pass through the positioning holes and are threadably connected to the threaded grooves.

[0013] Preferably, the connecting rod is fixedly sleeved with two limiting rings, and the two limiting rings are respectively located at two ends of the rotating tube.

[0014] Compared with the prior art, a wave power generation device using the above technical solution has the following beneficial effects:

[0015] 1. When the floating board floats on the sea, it will sway and rise on the sea surface with the surge of the waves. During the swaying and rising of the floating board, the pendulum will swing on the connecting rod with the rotating tube as the center under the action of gravity and inertia, and drive the arc frame to sway synchronously. The arc frame will drive the chain to move during the shaking process, and drive the sprocket to rotate during the movement. The sprocket will drive the rotating shaft and the driving gear to rotate synchronously during the rotation process. The driving gear will drive the driven gear and the rotating shaft of the generator to rotate synchronously during the rotation process by meshing with the driven gear. The rotating column of the generator can realize the use of sea wave power generation during the rotation process. The floating board floats on the sea surface, which can reduce the influence of tides during power generation and increase the efficiency of sea wave power generation.

[0016] Second, the wire will be connected to the battery, and the wire will be used to transfer the electric energy in the battery to the shore. At this time, the counterweight block falls under the floating board and contacts the seabed. Therefore, the floating board will be limited to float in a specific range on the sea surface by the counterweight block and the wire to prevent the floating board from being slowly pushed away from the position close to the coast by the waves. The staff can fix the threaded tube at different positions on the wire, and control the distance between the blocking ring and the floating board when fixing the blocking ring with the threaded tube, and then control the depth to which the counterweight block can fall in the sea, so that the floating board can be set on the sea surface at a corresponding depth according to the depth to which the counterweight block can fall, and the range of movement of the floating board on the sea surface can be controlled;

[0017] 3. The indicator light will flash continuously using the power in the battery. The flashing indicator light will remind passing ships at night that there are obstacles here and they should avoid them. This will ensure the safety of sailing ships and prevent the wave power generation device from being damaged by ships. The protective cover will protect the equipment installed on the floating board inside, which can prevent the splashed seawater from contacting with the equipment installed on the top of the floating board and causing corrosion, thereby increasing the safety of the equipment during use and extending the service life of the equipment.

[0018] 4. Before placing the floating board on the sea surface, the staff will first pass the two limit posts through the fixing rings on both sides of the protective cover, and then insert the limit posts into the seabed. At this time, the traction rope between the limit posts and the protective cover is in a state close to being tightened but not completely tightened, which can reserve space for the floating board to move with the ups and downs of the waves. By limiting the limit posts and the traction ropes on the protective cover, the swing direction of the floating board, the surge direction of the waves and the swing direction of the pendulum can be controlled to be basically in a straight line, thereby increasing the swing amplitude of the pendulum, thereby further enhancing the power generation effect of using sea waves to generate electricity;

[0019] 5. The staff can separate the damaged fixed frame or damaged floating plate from the intact part by unscrewing the fixing bolts from the threaded groove, so that the intact part can be retained for continued use, thereby reducing the cost of maintenance and increasing the speed of disassembling and assembling the fixed frame. When the rotating tube rotates on the connecting rod, since the rotating tube is between the two limit rings, the rotating position of the rotating tube on the connecting rod can be limited, thereby limiting the swing trajectory of the pendulum and preventing the pendulum from hitting the support frames on both sides, thereby increasing the stability of the pendulum when swinging.

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 3 and Figure 6-Figure 8 As shown, a wave power generation device includes a floating board 1, a fixing frame 2 is detachably provided on the top surface of the floating board 1, two support frames 3 are fixed on the top surface of the fixing frame 2, a mounting plate 4 is fixed on the top surface of the support frame 3, a connecting rod 9 is fixed between the two support frames 3, a rotating tube 10 is rotatably inserted on the connecting rod 9, an arc frame 11 is fixed on the rotating tube 10, a rocker 12 is fixed on the surface of the rotating tube 10, a pendulum 13 is fixed at the bottom end of the rocker 12, a positioning plate 5 is fixed on the top surface of the mounting plate 4, and a fixing hole 11 is opened on one side of the positioning plate 5 5. A bearing 7 is fixed inside the fixing hole 15. A rotating shaft 6 is fixed to the inner wall surface of the inner ring of the bearing 7. A sprocket 8 is fixedly sleeved on the rotating shaft 6. A chain 14 is fixed on the arc frame 11. The chain 14 and the sprocket 8 are meshed with each other. A driving gear 16 is fixedly sleeved on the surfaces of both ends of the rotating shaft 6. Two generators 17 are fixed on the top surface of the mounting plate 4. A driven gear 18 is fixed to one end of the output shaft of the generator 17. The driving gear 16 and the driven gear 18 are meshed with each other. A hemispherical plate 19 is fixed to the bottom surface of the floating board 1. A battery 20 is arranged inside the hemispherical plate 19. A PLC controller is arranged on the top surface of the floating board 1. The battery 20 is electrically connected to the PLC controller, and the generator 17 is electrically connected to the PLC controller.

[0031] During use, when the floating board 1 floats on the sea, the floating board 1 will sway and rise on the sea surface with the surge of waves. During the swaying and rising of the floating board 1, the pendulum 13 will swing on the connecting rod 9 with the rotating tube 10 as the center under the action of gravity and inertia, and drive the arc frame 11 to swing synchronously. The arc frame 11 will drive the chain 14 to move during the shaking process, and drive the sprocket 8 to rotate during the movement. The sprocket 8 will drive the rotating shaft 6 and the driving gear 16 to rotate synchronously during the rotation process. The driving gear 16 will drive the driven gear 18 and the rotating shaft of the generator 17 to rotate synchronously during the rotation process by meshing with the driven gear 18. The rotating column of the generator 17 can realize the use of wave power generation during the rotation process. The floating board 1 floats on the sea surface, which can reduce the influence of tides when generating electricity, thereby increasing the efficiency of wave power generation.

[0032] like Figure 4 As shown, a wire 21 is fixedly sleeved on the hemispherical plate 19, one end of the wire 21 is fixed to the battery 20, a counterweight 22 is slidably inserted on the wire 21, a threaded tube 23 is fixedly sleeved on the wire 21, and a blocking ring 24 is threadedly connected to the threaded tube 23.

[0033] During use, the wire 21 will be connected to the battery 20, and the wire 21 will be used to transfer the electrical energy in the battery 20 to the shore. At this time, the counterweight 22 falls under the floating board 1 and contacts the seabed. Therefore, the floating board 1 will be limited to float in a specific range on the sea surface by the counterweight 22 and the wire 21 to prevent the floating board 1 from being slowly pushed away from the position close to the coast by the waves. The staff can fix the threaded tube 23 at different positions on the wire 21, and control the distance between the blocking ring 24 and the floating board 1 when fixing the blocking ring 24 with the threaded tube 23, and then control the depth to which the counterweight 22 can fall in the sea, so that the floating board 1 can be set on the sea surface of the corresponding depth according to the depth to which the counterweight 22 can fall, and the range of movement of the floating board 1 on the sea surface can be controlled.

[0034] like Figure 2 As shown, a protective cover 25 is fixed on the top surface of the floating board 1, and an indicator light 26 is fixed on the top of the protective cover 25. The indicator light 26 is electrically connected to the PLC controller.

[0035] During use, the indicator light 25 will flash continuously using the power in the battery 20. The flashing indicator light 25 will remind passing ships at night that there are obstacles here and they should avoid them. This will ensure the safety of sailing ships while preventing the wave power generation device from being damaged by ships. The protective cover 25 will protect the equipment installed on the floating board 1 inside, thereby preventing the splashed seawater from contacting the equipment installed on the top surface of the floating board 1 and causing corrosion, thereby increasing the safety of the equipment during use and extending the service life of the equipment.

[0036] like Figure 2 As shown, two traction ropes 27 are fixed to the protective cover 25 , and a fixing ring 28 is fixed to the other end of the traction rope 27 . A limiting column 29 is slidably inserted inside the fixing ring 28 , and a blocking plate 30 is fixed to the top of the limiting column 29 .

[0037] During use, before placing the floating board 1 on the sea surface, the staff will first pass the two limit columns 29 through the fixing rings 28 on both sides of the protective cover 25, and then insert the limit columns 29 into the seabed. At this time, the traction rope 27 between the limit columns 29 and the protective cover 25 is in a state close to being taut but not yet completely taut, thereby reserving space for the floating board 1 to move with the ups and downs of the waves. By limiting the protective cover 25 through the limit columns 29 and the traction rope 27, the swing direction of the floating board 1, the surge direction of the waves and the swing direction of the pendulum 13 can be controlled to be basically in a straight line, thereby increasing the swing amplitude of the pendulum 13, thereby further enhancing the power generation effect of utilizing sea waves to generate electricity.

[0038] like Figure 5 and Figure 6As shown, a plurality of positioning holes 31 are provided on the top surface of the fixing frame 2, a plurality of threaded grooves 32 are provided on the top surface of the floating plate 1, a fixing bolt 33 is rotatably inserted inside the positioning hole 31, the bottom end of the fixing bolt 33 passes through the positioning hole 31 and is threadedly connected with the threaded groove 32, and two limiting rings 34 are fixedly sleeved on the connecting rod 9, and the two limiting rings 34 are respectively located at the two ends of the rotating tube 10.

[0039] During use, the staff can unscrew the fixing bolts 33 from the threaded grooves 32 to separate the damaged fixing frame 2 or the damaged floating board 1 from the intact parts, so that the intact parts can be retained for continued use, thereby reducing the cost of maintenance and increasing the speed of disassembling and assembling the fixing frame 2. When the rotating tube 10 rotates on the connecting rod 9, since the rotating tube 10 is located between the two limit rings 34, the rotating position of the rotating tube 10 on the connecting rod 9 can be limited, thereby limiting the swing trajectory of the pendulum 13 and preventing the pendulum 13 from hitting the support frames 3 on both sides, thereby increasing the stability of the pendulum 13 when swinging.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
