Wave power generation device and wave power generation method for underwater balanced type dual floating bodies

Abstract

The invention discloses a wave power generation device and a wave power generation method for underwater balanced type dual floating bodies. The device comprises a submarine bench, a transmission case and a pair of balanced type dual floating bodies, wherein the submarine bench is anchored on the seabed by virtue of a group of anchor chains or mooring ropes; the transmission case is arranged on the submarine bench, a first rope pulley and a second rope pulley are sleeved on one side end of a main shaft of the transmission case, and the output end of the transmission case is connected to a power generator; the pair of balanced type floating bodies comprises a group of surface floating bodies positioned on the water surface so as to collect wave energy and a group of underwater floating bodies soaked in the sea and positioned at a static water layer; the surface floating bodies and the underwater floating bodies are respectively pulled by one mooring rope; the lower ends of the mooring rope used for pulling the surface floating bodies and the mooring rope used for pulling the underwater floating bodies are respectively wound on the first rope pulley and the second rope pulley. According to the device and the method, a mode that the balanced type dual floating bodies work alternately and perform circulating continuous full-wave acting is adopted, so that the wave power generation efficiency is improved, and technical support is provided for realizing the commercialization of wave power generation.

Description

technical field [0001] The invention relates to the technical field of obtaining renewable energy through the development of ocean energy, in particular to a wave power generation device in deep sea areas. Background technique [0002] In the prior art, there are generally two forms of wave power generation devices in the deep sea: one is to fix the wave power generation device in the form of pile foundations by driving piles on the seabed, which is difficult to construct and expensive, and in the case of a small unit capacity It is even more uneconomical, and it cannot adapt to changes in ocean tides, so it has not been widely used so far. The other is the floating wave power generation device, which is fixed by anchor chains. Its shortcoming is that it cannot control the movement of the wave power generation device in the up and down direction. It just fixes the wave power generation device in a certain sea area. Among them, like flying a kite, its flexible containment is...

[0002] In the prior art, there are generally two forms of wave power generation devices in the deep sea: one is to fix the wave power generation device in the form of pile foundations by driving piles on the seabed, which is difficult to construct and expensive, and in the case of a small unit capacity It is even more uneconomical, and it cannot adapt to changes in ocean tides, so it has not been widely used so far

The other is the floating wave power generation device, which is fixed by anchor chains. Its shortcoming is that it cannot control the movement of the wave power generation device in the up and down direction. It just fixes the wave power generation device in a certain sea area. Among them, like flying a kite, it is flexible and does not hang vertically on the seabed. Therefore, it is inefficient to use anchor chains to fix the working parts of the wave power generation device. This is also the main reason why wave power generation has not been commercialized so far.
