TECHNICAL FIELD

[0001] The utility model relates to wave energy power generation technical field especially relates to a wave energy power generation device's energy conversion mechanism. BACKGROUND

[0002] With the increasing global energy demand and the growing environmental protection consciousness, the development and utilization of renewable energy become particularly important. As a widely distributed and abundant renewable energy, the development and utilization of wave energy have great potential. However, the existing wave energy power generation device often has low energy conversion efficiency, complex structure, poor adaptability and other problems, which limits the wide application of wave energy power generation technology.

[0003] Most of the traditional wave energy power generation devices use floating bodies or swing structures to capture wave energy and convert it into mechanical energy or electrical energy. However, these devices often have difficulty in self-adaptive adjustment according to the amplitude of the wave, resulting in reduced energy conversion efficiency when the wave is small or large. In addition, the structure of some devices is complex, the maintenance cost is high, and it is difficult to adapt to the wave conditions of different sea areas. SUMMARY

[0004] The utility model aims at solving the shortcomings that the device in the prior art often has difficulty in self-adaptive adjustment according to the amplitude of the wave, resulting in reduced energy conversion efficiency when the wave is small or large. In addition, the structure of some devices is complex, the maintenance cost is high, and it is difficult to adapt to the wave conditions of different sea areas, and proposes a wave energy power generation device energy conversion mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A wave energy power generation device energy conversion mechanism, comprising a mounting box, one side of the mounting box is fixedly connected with a second connecting rod, one end of the second connecting rod is rotatably connected with a fixed shaft, the outer wall of the fixed shaft is fixedly connected with a plurality of first connecting rods, the outer wall of a plurality of first connecting rods is fixedly provided with a same arc block, one end of the arc block is embedded with a counterweight, the counterweight is eccentrically arranged, one side of the arc block is provided with an arc hole, the inside of the arc hole is provided with an adjusting assembly for adjusting the swing amplitude of the arc block.

[0007] The inside of the mounting box is provided with a power generation assembly for power generation.

[0008] In a possible design, the adjusting assembly comprises two arc-shaped sliding grooves respectively formed in the inner walls of the two sides of the arc-shaped hole, a plurality of limiting grooves are formed in the inner wall of one side of the arc-shaped sliding groove, two arc-shaped sliding blocks are slidably connected in the inside of the arc-shaped sliding groove, and the four arc-shaped sliding blocks are symmetrically arranged in pairs.

[0009] In a possible design, the arc-shaped slider is internally slid through a limiting rod, one end of the limiting rod is clamped with a limiting groove, and one end of the limiting rod is fixedly connected with a pull plate.

[0010] In a possible design, the pull plate and the limiting rod are internally provided with a same circular groove, the same circular rod is slid through the two circular grooves, and the two ends of the circular rod are fixedly connected with the same first spring between the inner walls of the two circular grooves.

[0011] In a possible design, the power generation assembly comprises a first rotating shaft rotatably connected to the inner wall of one side of the mounting box, the inner wall of one side of the mounting box is provided with a generator, one end of the first rotating shaft is fixedly connected with an input shaft of the generator, the outer wall of the first rotating shaft is provided with two symmetrical one-way bearings, and the outer wall of the one-way bearing is fixedly sleeved with a second gear.

[0012] In a possible design, a second rotating shaft is rotatably connected between the inner walls of the two sides of the mounting box, the outer wall of the second rotating shaft is fixedly sleeved with two symmetrical first gears, the two first gears are respectively engaged with the two second gears, the mounting box is slid through two symmetrical push rods on one side, one end of the push rod is fixedly connected with a rack, the rack is engaged with the first gear, and one end of the rack is fixedly connected with the same second spring between the inner wall of one side of the mounting box.

[0013] In a possible design, the outer wall of the arc-shaped block is fixedly connected with two symmetrical protrusions, and the protrusions abut against the push rods.

[0014] In a possible design, the circular rod is in interference fit with the circular groove.

[0015] In the present application, when in use, the device is fixed beside the bank, the protruding part of the arc-shaped block slightly exceeds the surface, when waves appear on the water surface, the waves will push the arc-shaped block to rotate, at this time, the arc-shaped block is gradually rotated to an inclined state, one side of the arc-shaped block drives the protrusions to move horizontally;

[0016] At this time, the protrusions push the push rods to move horizontally, the push rods drive the rack to move horizontally, the rack extrudes the second spring, at this time, the rack drives the first gear to rotate, the first gear drives the second rotating shaft to rotate, the first gear simultaneously drives the second gear to rotate, the second gear drives the first rotating shaft to rotate, and thus the power generation process can be completed through the generator;

[0017] When there are no waves on the water surface, at this time, the arc-shaped block is reset under the weight of the counterweight, and the push rod is also reset under the elastic force of the second spring, due to the arrangement of the one-way bearing, the first rotating shaft cannot be reversed at this time, and when waves appear again, power generation will be performed again, and the process is repeated.

[0018] And the device can adjust the rotation amplitude of the arc-shaped block according to the amplitude of the waves. By pressing the two pull plates, the two pull plates are brought close to each other, the pull plates drive the two limiting rods to move close to each other, the limiting rods press the first springs, and the pull plates slide on the outer wall of the round rod. When the limiting rods move out of the limiting grooves, the arc-shaped slider is released from the braking state. After adjusting the positions of the two arc-shaped sliders, the two pull plates are released, and the positions of the pull plates can be adjusted. The pull plates abut against the second connecting rod, and the angle of the arc-shaped block during rotation can be adjusted.

[0019] Beneficial effects: By adjusting the setting of the assembly, the application can adjust the rotation amplitude of the arc-shaped block according to the amplitude of the waves, thereby optimizing the energy conversion process. When the waves are large, the arc-shaped block can rotate a larger amplitude to capture more wave energy; when the waves are small, the arc-shaped block rotates a smaller amplitude to avoid excessive wear and energy loss. This adaptive adjustment mechanism improves the flexibility and efficiency of energy conversion.

[0020] The structure of the application is relatively simple, mainly composed of a mounting box, an arc-shaped block, an adjusting assembly, and a power generation assembly. The connection and transmission mode between these components are clear and easy to maintain and maintain. At the same time, the use of one-way bearings and other mechanical elements ensures the stable operation of the device and the continuity of energy conversion.

[0021] Through the setting of the power generation assembly, the application can efficiently convert wave energy into electrical energy. When the arc-shaped block is driven to rotate by the waves, it will move the protrusion and the push rod, thereby driving the rack and pinion transmission system to work, and finally driving the generator to generate electricity. This transmission mode has high energy transmission efficiency and stability.

[0022] The wave energy power generation device energy conversion mechanism of the application has strong adaptability and can be applied to different wave conditions in different sea areas. By adjusting the position and angle of the arc-shaped slider, the rotation amplitude of the arc-shaped block can be accurately controlled, thereby meeting the wave energy power generation needs in different regions and sea areas.
