Abstract

The invention discloses a wave power generation device and a control method of the wave power generation device. The wave power generation device comprises a supporting frame, a power generation device, a controller and an overwater device. The overwater device comprises a roller, a rotary shaft, fixing rings, two cables, pressure sensors, gasbags, igniters, main rivets and a plurality of side rivets; the rotary shaft is arranged in the roller; the fixing rings are connected with the two ends of the rotary shaft in a sliding manner; the two cables are connected with the two fixing rings separately; the pressure sensors are arranged at the lower portions of the cables; the gasbags, which are capable of extending vertically and located in metal pipes, are arranged at the lower ends of the cables; the igniters are connected with the gasbags; the main rivets are, located in the metal pipes, are arranged below the gasbags; a hollow cavity is arranged in the roller and the hollow cavity is filled with hydrogen. The device has the characteristics of being wide in application range, high in energy transformation efficiency and good in stability.

Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to a wave power generation device with wide application range, high energy conversion efficiency and good stability and a control method. Background technique [0002] The development and utilization of marine energy is the direction of energy research. Under the situation that the earth's mineral energy is gradually depleted and the environmental situation is deteriorating, how to effectively use the abundant and renewable marine resources is very important; [0003] Wave energy is the cleanest renewable resource. The power of wave energy dissipated continuously along the coastline in the world reaches 27×105MW, and the technically available wave energy potential is 10×105MW. [0004] The existing wave power generation devices have the disadvantages of high price, low energy conversion efficiency and limited installation area. Contents of the invention [0005] The...
