The invention discloses a sea wave energy bidirectional efficient absorption power-generation device. The sea wave energy bidirectional efficient absorption power-generation device comprises a rectifying device, a float, a first power generator and a base; a rotating shaft of the first power generator downwards vertically penetrates through the float in a rotary sealing mode and then is fixedly connected with a unidirectional impeller; four circular rings are arranged at the edge of the float, the base is provided with a plurality of fixed pulleys and a second power generator, the space between the float and the second power generator is in transmission connection with two elastic flexible ropes, the two ends of one of the elastic flexible ropes are fixed to the two circular rings arrangedoppositely, the middle of one of the elastic flexible ropes passes through the fixed pulleys, turns and then is wound with a stator shaft of the second power generator, the two ends of the other elastic flexible rope are fixed to the other two corresponding circular rings arranged oppositely, the middle of the other elastic flexible rope passes through the fixed pulleys, turns and then is wound with a rotor shaft of the second power generator. The sea wave energy bidirectional efficient absorption power-generation device is simple in structure and convenient to mount, up-down floating energyin sea can be utilized, energy of undercurrent surging in the horizontal direction can further be utilized, and the sea wave energy bidirectional efficient absorption power-generation device has quitehigh applicability in the deep sea, shallow sea and seaside construction area.
Description
technical field [0001] The invention relates to the fields of electrical engineering and its automation motors and electrical appliances, in particular to a two-way high-efficiency absorption power generation device for ocean wave energy. Background technique [0002] In 1799, France applied for the world's first patent on wave energy. In the 1960s, Japan first developed a commercialized wave energy power generation device for navigation lights. The oil crisis in 1973 promoted the development of renewable energy and stimulated people's interest in obtaining energy from the ocean. Japan, South Korea, Britain, France, the United States, Italy and many other western countries conducted in-depth research on wave energy utilization technology. Due to environmental factors such as the high energy density of European waves, researchers from various countries have designed and tested various types of wave energy generation devices; Large-scale megawatt-level, realize grid-connecte...
