Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to an ocean wave power generation device. Background technique [0002] my country has abundant wave energy resources, and the wave energy reserves in most sea areas are more than 2Kw / m. In the South China Sea, the energy flow density can reach more than 2Kw / m, the wave height is about 1.5m, and the wave period is 6s. It can be developed and utilized. When the wave energy is greater than 1.3m, it can be developed for power generation. [0003] However, the total marine energy reserves in China are huge, which is several times that of my country's installed power capacity. However, in regions with such rich wave energy, remote places such as islands have many problems in terms of power supply compared with the mainland. For medium and large islands, in order to meet the needs of life and production on the island, it is often necessary to build an expensive submarine power...

Problems solved by technology

However, small islands are usually not connected to the mainland power grid, and local residents usually cannot get a stable power supply for daily electricity consumption, which causes inconvenience to the development and utilization of these islands

[0004] However, the existing wave power generation device absorbs seawater and converts the potential energy of seawater into electric energy, but the conversion rate of this mode is not high, and a lot of energy will be lost in the middle; for example, Chinese patent application CN201810112448.0 discloses a wave power generation The device requires a large number of floating bodies to maintain normal power generation, and there will be a large amount of wave energy loss between the floating bodies, which is not fully utilized, and the wave energy is seriously wasted; at the same time, the power generation equipment needs to be in contact with seawater for a long time, and seawater has A certain degree of corrosiveness, so long-term, it is easy to damage the power generation equipment, and the maintenance cost is high. In addition, in the face of extreme offshore weather, the power generation device will face huge safety risks
