[0003] 1. Chinese invention patent application publication CN 101900073 A discloses a wave power generation device.

AI Technical Summary

Problems solved by technology

[0004] The floating body of the above-mentioned wave power generation equipment and the rack and tooth column fixed on the floating body move up and down with the wave. When the wave pushes the float upward, the rack and the tooth column of the rectangular frame will extend upward to the gear (that is, the one-way gear) , when the float reaches the highest point, its protruding height is not less than a wave height; generally, the wave height is about 2 to 3 meters, and this wave height is ideal for power generation, sometimes higher; because at this time, the rack, tooth column, etc. Parts protrude too much from the gear, so the whole device is unstable and the ability to resist wind and waves is weakened

[0005] The guide device for the up and down movement of the oscillating buoy of the above-mentioned wave power generation equipment is realized by the two guide wheels on the buoy and the cooperating column and the tooth column limit wheel. The lateral force, side bending force and torsional force from the wave, There is also the beating force of waves on the sea surface, which acts on the float, gear, rack and tooth column. Due to the weak bearing capacity of this structure, it is easy to be damaged, resulting in the instability of the entire equipment and insufficient wind and wave resistance.

[0006] 2. Chinese invention patent application publication CN 103114958 A discloses a mechanical combined oscillating buoy wave energy generating device, which includes a power generation system and a fixing system; the fixing system includes a buoyancy tank and a fixing frame, and the fixing frame is a cube structure. It is fixedly connected to the top of the floating tank, and the four corners of the side of the fixed frame are respectively equipped with columns; the power generation system is composed of four sets of the same power generation mechanism, and each set of power generation mechanism includes a float, an energy conversion device and an energy output device; The holes are set on the column; the energy conversion device includes a rack fixed on the column and a one-way gear (load gear) fixed on the float; the rack and pinion mechanism converts the linear motion of the float into rotary motion and outputs it to Rotate the generator to complete the conversion from wave energy to electric energy; the device places generators, conversion gears and other mechanism equipment on the oscillating float platform that keeps moving up and down. When the oscillating float is at the lowest point, the column together with the The rack will protrude a very high distance from the gear, causing the entire equipment to be unstable. At the same time, there is also an unstable operating platform and it is very difficult to work on the platform. It is difficult for this device to realize multiple independent buoy power systems through mechanical The shafts are connected in series, thereby reducing the fluctuation of the speed and achieving the purpose of stable power generation

[0007] 3. China Utility Model Patent Authorization Announcement No. CN 201687642 U discloses a marine wave energy power generation device. The device adopts a double-sided rack and pinion mechanism. The rack is fixed on the oscillating float and moves up and down with the oscillating float. Disadvantages brought by the lateral force, the rack chute is designed for the double-sided rack. This measure still cannot solve the problem of the weak ability of the oscillating buoy power generation device to resist wind and waves due to the excessively long upward extension of the rack.

[0008] 4. In the first issue of "Coastal Engineering" magazine published in 2016, the article "Research and Design of Wave Energy Oscillating Float Conversion Experimental Device" disclosed a vertical vibration type oscillating float wave energy power generation system, which is a rack and pinion The typical device of the wave energy conversion method of the transmission oscillating float; the power generation system composed of a single typical device, or the power generation system composed of multiple typical devices, there is a problem that the rack protrudes upwards with the upward movement of the oscillating float, causing instability.

[0009] For the problems of the rack-and-pinion mechanism and the guiding device in the above-mentioned prior art, the resulting oscillation float is unstable in up and down movement, which leads to weakening of the anti-wind and wave ability of the entire power generation device

Although a variety of improvement measures have been adopted, none of them can fundamentally solve the problem
