[0002] Wave energy is rich and has great potential for development and utilization. At present, there are many types of wave energy utilization technologies, but floating wave energy utilization technology has become the mainstream of world research due to its wide adaptability. Floating oscillating buoy technology uses wave energy to push one floating body to translate or rotate relative to another floating body to convert energy. The device developed based on this technology must be a double floating body and must be submerged or semi-submerged in the seawater. This feature means that the material utilization rate is low, the problem of collision between floating bodies is inevitable, the impact of marine organisms attachment is large, and the deployment time is long. Its cost-effectiveness is limited by the technical route. Floating overtaking technology uses the climbing effect of waves to convert wave energy into the potential energy of seawater. The device developed based on this technology is characterized by a single floating body, and the device must bear the weight of the conversion carrier. Therefore, its structure is strong and large, and the energy conversion efficiency is low. Summary of the invention

[0018] 4. By arranging a forward and reverse scraper device on the filter and linking it with the rotating part, the wave water flow is used to drive the rotating part to rotate and drive the forward and reverse scraper device to rotate, so that the forward and reverse scrapers can cut and remove seaweed and other marine plants or marine garbage floating on the filter, so as to reduce the growth or adsorption of seaweed and other marine plants on the filter, thereby causing the filter to be blocked, which can easily cause the horizontal pipe resistance to increase, the water flow in the horizontal pipe to decrease, and the rotating part to be unable to rotate; through the movement of the forward and reverse scraper device, the working efficiency of the rotating part is effectively improved and the problem of filter blockage is reduced.

[0019] 5. By setting a reverse scraper, the transmission shaft drives the reverse scraper to rotate on the surface of the filter under the drive of the rotating component, so as to remove the shellfish adsorbed on the filter and reduce the problem of its growth and spread to block the filter.

[0035] Specifically, an air chamber 8 is formed between the liquid surface in the vertical cavity 5 and the air turbine 6. When the waves rise, the water flows into the horizontal pipe 4, and at the same time, the air in the air chamber 8 is pushed up. The compressed air drives the air turbine 6 on the shaft extension end of the generator 7 to make the generator 7 generate electricity. The electric energy generated by the generator 7 is transmitted to the energy storage device 3 for storage, and is powered by the energy storage device 3 when in use.

[0041] Specifically, the forward scraper 21 and the reverse scraper 22 are arranged in an alternating and overlapping manner on one side of the filter screen 12, so that the forward scraper 21 and the reverse scraper 22 are tangent to each other during the forward and reverse rotation process, so that the forward scraper 21 and the reverse scraper 22 can cut and remove marine plants such as seaweed or marine garbage when they rotate to be tangent, thereby improving the removal efficiency of marine plants such as seaweed or marine garbage.

[0042] By arranging a forward and reverse scraper device on the filter 12 and linking it with the rotating component 10, the rotating component 10 is driven to rotate by wave water flow to drive the forward and reverse scraper device to rotate, so that the forward and reverse scrapers can cut and remove seaweed or other marine plants or marine garbage floating on the filter 12, so as to reduce the growth or adsorption of seaweed or other marine plants on the filter 12, thereby causing the filter 12 to be blocked, which can easily cause the resistance of the horizontal pipe 4 to increase, the water flow in the horizontal pipe 4 to decrease, and the rotating component 10 to be unable to rotate; through the movement of the forward and reverse scraper device, the working efficiency of the rotating component 10 is effectively improved and the problem of filter 12 blockage is reduced.
