Adaptive traction-type tidal current energy power generation device

Abstract

The invention provides an adaptive traction-type tidal current energy power generation device, which comprises a main buoy, two side buoys, two connection arms, a universal coupling, a connecting rod, a base and two water turbines, wherein the side buoys are respectively symmetrically arranged on two sides of the main buoy; the water turbines are installed on the corresponding side buoys by the connection arms; one end of the connecting rod is hinged to the main buoy, the other end of the connecting rod is connected to the universal coupling, and the universal coupling is installed on the base; one end hole of the main buoy is provided with a water inlet and outlet; the other end part of the main buoy is provided with an air valve. According to the adaptive traction-type tidal current energy power generation device, the universal coupling is used for guaranteeing that the rotary planes of the water turbines still face to the coming direction of tidal current so as to improve energy acquisition efficiency. Meanwhile, the invention provides a cruciform floating body structure of which the main buoy and the side buoys are combined, and the main buoy is subjected to air inflation water discharge and air deflation water feeding to cause the water turbines to lift so as to bring convenience for installing and maintaining the water turbines.

Description

technical field [0001] The invention belongs to the technical field of ocean energy development, and relates to a tidal current energy generating device, in particular to an adaptive traction type tidal current energy generating device. Background technique [0002] The development of the economy is accompanied by the consumption of energy. In recent years, the problem of energy shortage in the world has become more and more serious. As a supplementary energy source, the development of ocean energy has attracted more and more attention from all over the world, and the development technology of ocean energy has developed rapidly. The lift-type ocean energy power generation device mainly uses the lift effect generated when the fluid flows through the blades to generate the torque that drives the turbine to achieve energy conversion. If the energy harvesting efficiency of the lift turbine is to be improved, the rotational axis of the blades of the turbine should be able to aut...
