Its development and utilization are very important to alleviate the energy crisis and reduce environmental pollution. The movement of turbulent waves produces huge, eternal and environmentally friendly energy. If the kinetic energy of waves and the wave energy of other water surfaces can be fully utilized, the future of world energy will be quite broad and bright.
目前的波浪能采集功率小、造价高、转化率低，集中化和商业价值低。The current wave energy collection power is small, the cost is high, the conversion rate is low, and the centralization and commercial value are low.

The present invention provides a new wave energy buoyancy power generation scheme and its working method, which is different from previous wave power generation devices that use buoyancy to change the displacement of the floating body and utilize the potential energy generated by the periodic wave motion of the floating body in the water for energy conversion and utilization. It consists of a floating body, a connecting rod group, a holder, and a fixed power generation device. The idea of the invention is to change the previous idea of using the center point water surface space for wave energy, change the displacement, have greater potential energy in the waves, enhance the power, have a simple structure and easy implementation, convenient daily maintenance of the facilities, and green and sustainable development.

取用排水2000KG船型浮体在水面中上下浮动（水上面积预定为4平方米），受波浪影响上下浮动。（浮动区间暂定30公分，那么浮体在上下浮动中可以得到1000KG以上的浮力势能或重力势能，也就是超过9800N，驱动电机运转进行发电）。A 2000KG boat-shaped floating body is used to float up and down in the water (the water area is scheduled to be 4 square meters), and it floats up and down under the influence of waves. (The floating interval is tentatively set at 30 centimeters, so the floating body can obtain more than 1000KG of buoyancy potential energy or gravity potential energy when floating up and down, that is, more than 9800N, and drive the motor to operate to generate electricity).
优选的取用密度500KG/每立方米的材料，体积为长2m*宽2m*高1m的立方体，吃水线在高0.5m处。海浪中取值为2022年5月13天气预报，中国启东市离岸20公里处，坐标122°00′11″E 31°50′42″N，浪高0.4-0.8m。在波浪运动中，浮体会被抬高并下落，得到一个周期运动，带动以偏心轮转子、或连杆组连接转子运动，浮体受波浪上下运动得到的抬升浮力及下落重力，转子都将获得一个超过9800N（保守的取值1000KG）的扭矩力，来带动能量收集装置。It is preferred to use materials with a density of 500KG/per cubic meter, a volume of 2m long*2m wide*1m high, and a waterline at a height of 0.5m. The value in the wave is based on the weather forecast on May 13, 2022, 20 kilometers offshore from Qidong City, China, with coordinates 122°00′11″E 31°50′42″N, and wave height 0.4-0.8m. In the wave motion, the floating body will be lifted up and down, resulting in a periodic motion, which drives the eccentric rotor or connecting rod group to connect the rotor. The floating body will receive the lifting buoyancy and falling gravity obtained by the up and down movement of the waves, and the rotor will obtain a A torque force exceeding 9800N (conservative value 1000KG) is used to drive the energy collection device.
