Problems solved by technology

Floating static oscillating water column technology The floating body basically does not move, and the movement of the water column in the cavity is mainly generated by the direct action of waves, such as the "Giant Whale" device in Japan. The energy conversion efficiency of this type of technology is not high
The existing wave energy utilization technology has the disadvantages of high construction cost, high cost of marine engineering, and low safety

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a single-valve U-shaped tube oscillating water column pair-equipped double-impulse turbine wave power generation device. Background technique [0002] Wave energy resources are abundant and have great potential for development and utilization. However, due to factors such as unstable wave energy, harsh marine environment, seawater corrosion, and marine organisms, the cost of developing and utilizing ocean wave energy is high. These costs are mainly reflected in the material cost of the device, construction cost, conversion mechanism cost, launch, transportation and recovery cost, anchoring cost, maintenance cost, etc. [0003] At present, there are many types of wave energy utilization technologies, and the floating wave energy utilization technology has become the mainstream of research because of its wide adaptability. Float technology such as figure 1 s...
