Problems solved by technology

The pendulum device is suitable for the characteristics of low frequency and large thrust of sea waves, has high conversion efficiency, and can be easily combined with phase control technology, but the maintenance of its mechanical and hydraulic mechanisms is relatively difficult
The advantage of the Jubo reservoir device is that there are no moving parts in the primary conversion, good reliability, low maintenance costs, and relatively stable system output; the disadvantage is that this type of power generation has special requirements for terrain during construction, and it is not easy to popularize

Abstract

The invention belongs to the fields of ocean utilization and renewable energy source generation, relates to a float type seawave power generation device, and is characterized by comprising a floating body, a balance floating body, a pulley, a rope, an input shaft, a clutch, an output shaft, a flywheel, a permanent magnet synchronous generator and an AC-DC-AC power converter, wherein, the floating body and the balance floating body are connected at two sides of the pulley through the rope; the pulley is coaxial with the input shaft; the input shaft is connected with the output shaft through the clutch; the clutch is used for leading the output shaft to rotate in one direction; the flywheel coaxial with the output shaft is fixed on the output shaft; the other end of the output shaft is connected with the permanent magnet synchronous generator; and the output of the generator is connected with the AC-DC-AC power converter. The float type seawave power generation device of the invention utilizes the energy when the floating body descends in a vertical direction, which can reduce design difficulty of small machinery and hydraulic mechanisms, is also beneficial for the realization of the largest wave energy capturing control strategy.

Description

technical field [0001] The invention belongs to the field of ocean utilization and renewable energy power generation, and in particular relates to an ocean wave power generation device. Background technique [0002] Environmental pollution and energy crisis are two common themes in the development of the world today. Vigorously developing wind power generation, wave power generation, tidal power generation, geothermal power generation and other new energy power generation methods, and realizing the change of energy conversion mode and the improvement of utilization rate are an important means to solve these two problems. Sustainable development plays an important role and has significant economic and social benefits. Vigorously developing marine renewable energy technologies, including wave power generation, has been included in the outline of the national marine development plan. So far, according to the different modes of action between wave power generation devices and ...
