Rectangular Ring Tube Oscillating Water Column Symmetrical Wing Turbine Power Generation Device

Abstract

The invention discloses a rectangular annular pipe type oscillating water column symmetrical wing turbine generation device, comprising a rectangular buoyancy tank, a deck, rectangular annular pipes,a generator, symmetrical wing turbines and a flow guide body, wherein the deck is arranged on the upper part of the rectangular buoyancy tank and is a horizontal plate, the rectangular annular pipes surround the four sides of the rectangular buoyancy tank in the upper and lower directions; the rectangular annular pipes are divided into left pipes, right pipes, upper pipes and lower pipes by takingthe rectangular buoyancy tank as a reference; the left pipes are symmetrical with the right pipes; the generator, the symmetrical wing turbine and the flow guide body are installed in the upper pipes; the symmetrical wing turbines are located at the centers of the upper pipes, the generator and the flow guide body are respectively located at two sides of the symmetrical wing turbines; the whole pipeline of the rectangular annular pipes is in a sealing state, and the rectangular annular pipes are filled with liquid medium and air. The device has the advantages of simple structure, safety and reliability, high conversion efficiency, convenient maintenance, ability of adjusting natural frequency of the device and reducing towage resistance.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a rectangular ring tube type oscillating water column symmetrical wing turbine 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 shown. Floating a...

AI Technical Summary

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
