Abstract

The invention relates to a tidal current generator, in particular to a double-rotor tidal current generator. According to the scheme, two energy collecting devices are arranged up and down and can greatly improve the energy collecting efficiency, and the utilization rate of tidal current energy is greatly increased. The double-rotor tidal current generator has the advantages that the structure design is simple, a yaw mechanism is not needed, and the generator is not affected by water flow directions; vertical blades are adopted, and compared with a horizontal shaft type water turbine, the machining difficulty of blades is lowered, and the development cost can be lowered; the energy obtaining coefficient and the tidal current energy utilization rate can be effectively increased.

Description

technical field [0001] The invention belongs to the field of marine renewable energy development, and relates to a tidal current generator, in particular to a double-rotor tidal current generator. Background technique [0002] The trend has the characteristics of high energy flow density, reciprocation, no pollution, and renewable. The core of tidal current power generation is the water turbine that absorbs the tidal current. The horizontal axis turbine has a large single unit power and is known as an "underwater windmill", but its comprehensive energy capture efficiency for reciprocating tidal currents is low. Compared with the horizontal axis, the vertical axis tidal current turbine has the following advantages: firstly, since the flow direction of the water flow has basically no influence on the vertical axis tidal current turbine, not only can the design of the yaw mechanical system be abandoned, but also the torque can be directly transferred through the rotating shaft...
