Background

The multi-float wave power generation apparatus has problems in practical applications such as (patent number 201320274905.9, a working platform for energy conversion power generation for gathering ocean wave energy): 1, the design of the platform is unreasonable, and the floating body of the platform bracket is blocked at two sides of the acting floater, so that the wave conduction to the floater is blocked, and the acting floater has no wave action; 2, the platform bracket adopts a strip-shaped structure, is extremely unstable, and is difficult to resist the transverse attack of the billows when typhoons come; 3, the diameters of the acting floats on the water surface are the same as those of the acting floats under the water surface, and the energy absorption efficiency is poor; 4 the float diameter and the local average wavelength are not optimally chosen, resulting in either too small a float diameter, requiring many floats, increasing costs, or too large a float diameter, affecting the up and down travel, resulting in reduced efficiency.

The yaw plate (duck type) wave power generation device has the following problems in practical application, such as a wave collecting plate of israel: 1, a fixed platform is adopted, and piling is needed at sea, so that the cost of the platform is high; 2. if attached to other buildings, such as dikes, wharfs, which are not expected to be result-wise due to the increased stress of the original design without reserved power generation equipment, the building owners will typically reject the extraneous attachment; the arm of force is too short, the swing amplitude of the swing plate is too small, and ravages of high waves of 10 meters cannot be resisted; the vertical projection area of the 4-pendulum plate (duck body) on the water surface is the same as that of the vertical projection area of the 4-pendulum plate (duck body) under the water surface, the response is not observed in practice when the wave height is 0.8 meter, namely, the floating body has no stroke, and the energy absorption efficiency is extremely poor; 5, the wave-facing width of the swinging plate is too small, so that the single swinging plate has low power and high cost; 6. other yaw (duck, hawk) type board wave power generation equipment, because its floating platform resembles a ship, submarine, the platform cost accounts for more than 80% of the total cost, resulting in the total cost being too high to be commercially valuable.

The development trend of the future multi-float and yaw plate wave power generation equipment is as follows: the power generation device with strong capability of resisting the platform wind and low construction, throwing, fixing and power transmission cost is developed. Only has strong typhoon resistance capability, and can survive; high efficiency, simple design, low cost and commercial value.

The utility model builds a floating platform which does not stop waves coming transversely, and a plurality of floats and a plurality of yaw plates can be arranged on the floating platform. The floating platform is actually a steel structure and can float on the sea; because the floating body with the rigid structure has smaller residual buoyancy, most of waves can pass through the platform, the acting force of the waves borne by the platform is very small, and the ravages of typhoons with more than 12 stages are easily resisted due to firm welding. The oscillating floater is arranged on the platform and fluctuates along with waves, the platform is larger and does not fluctuate along with the waves, the floater and the platform form relative motion, moment is generated, and the electric power can be converted; and a yaw plate is arranged beside the platform, a floating body of the yaw plate moves up and down along with waves, a variable included angle is formed between the power arm and the platform, and a conversion device is arranged between the power arm and the platform, so that electric power can be generated.

according to archimedes' law: the buoyancy of the floating body is greater than the gravity, and the floating body can float on the water surface; i.e. the floating body can float on the water surface when the displacement is larger than the gravity. The overall displacement of the platform bracket is larger than gravity, so that the platform bracket can float on the sea surface.

Experiments prove that the floating body with more than one wavelength can reduce the fluctuation amplitude along with the waves, and the more the floating body with more than one wavelength is, the smaller the swing amplitude is, for example, the floating body can not basically fluctuate along with the waves in the sea on an aircraft carrier sailing in the sea. The platform can be made into a length larger than one wavelength according to the wavelength of the local sea area, and the platform can not fluctuate up and down along with waves basically due to the fact that the damping plate is arranged at the bottom.

The oscillating floater and the yaw plate which are arranged on the platform are easy to move up and down along with waves because the diameters of the oscillating floater and the yaw plate are much smaller than the wavelength; thus, relative motion is formed with the platform, moment is generated, and the moment is converted into electric power.

The utility model has the beneficial effects that:

1. designed into a frame structure, and can be made into a larger platform by using less steel.

2. Due to the frame structure, the wave penetration capacity is strong, namely the acting force of the wave on the platform is small, and the wind energy resistance capacity is strong.

3. And the damping plate is arranged below the platform, so that the stability of the platform is greatly improved.

5. The platform frame is reasonable in design, and a plurality of oscillating floats and yaw plates can be installed side by side to form a so-called array device.

6. Because reasonable in design, the platform body structure is mostly under the surface of water, just so can not stop the effort of wave to vibration float, lets vibrate float and yaw board and obtain sufficient wave energy easily.

7. The vibrating floats and the yaw plates doing work can resist typhoon and billows due to reasonable design, respond timely, and capture wave energy efficiency is high.
