Abstract

The invention discloses a U-shaped flow channel impulse turbine suitable for oscillating water column type wave power generation. The air turbine comprises a hub, moving blades, moving impellers, arc-shaped guide sections and guide blade sections; the two ends of the hub are provided with the corresponding moving impellers; the moving impellers rotate about the hub; the moving impellers are correspondingly provided with the moving blades; moreover, the two arc-shaped guide sections connected with each other are arranged at the two sides of the moving impellers; the guide blade sections are arranged circumferentially at the end parts, away from the moving impellers, of the arc-shaped guide sections correspondingly; and each guide blade section is provided with a circle of guide blades evenly arranged in the circumferential direction. The air turbine has high energy conversion efficiency, a good self-starting property, relatively low working speed, a relatively wide flow coefficient range and relatively small working noise.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a U-shaped channel impact turbine suitable for oscillating water column wave energy power generation. Background technique [0002] Ocean wave energy, like the current rapidly developing solar energy and wind energy, is a renewable clean energy with abundant reserves of up to 2 billion kilowatts. After more than 20 years of research and development, scientists from many countries and regions in the world have proposed more than 300 wave power generation devices and more than 1,500 wave energy conversion technology patents. However, problems such as how to efficiently utilize ocean wave energy have not yet been well resolved, and these problems have seriously hindered the industrialized development of wave energy utilization. [0003] According to the different working principles of the devices absorbing wave energy, wave energy power generation devices can be ...
