Abstract

The invention discloses a double-vertical-shaft and double-rotor tidal current energy water turbine power generation system, and belongs to the technical field of renewable energy sources. The systemcomprises a vertical shaft water turbine rotor power generation device, gear transmission devices and a seabed pedestal. Two rotors are vertically installed in parallel and conduct relative rotation.Blades are arranged along the rotating faces in an equal interval angle mode and connected to rotating shafts through connecting rods. Each rotating shaft is connected with a supporting framework through an upper bearing and a lower bearing. A bottom supporting plate is fixedly connected with pile leg connecting components. The tidal current energy conversion system can be connected with two generators or one generator through the gear devices. When the double generators work, the rotor rotating shafts are connected with different generators through the gear devices and independently work; andwhen the single generator works, the rotor rotating shafts are connected to a double-rotating-shaft generator through the gear devices. The two rotors conduct relative rotation under the action of the incoming flow and have the beneficial influence on each other, the pulsation characteristic of the system is reduced, the rotating speed of each rotor is increased, and the energy conversion efficiency of the power generation device is greatly improved.

Description

technical field [0001] The invention relates to a tidal current energy water turbine power generation system with double vertical shaft rotors, which belongs to the technical field of renewable energy. Background technique [0002] As a clean and renewable energy, ocean energy has the characteristics of large reserves and wide distribution. At present, the development and utilization of ocean energy by human beings is concentrated in two forms: ocean wind power generation and tidal current power generation. Among them, tidal current power generation technology is relatively mature and widely used. Tidal current energy is the fluid kinetic energy carried by seawater in the process of ebb and flow, and has the characteristics of energy concentration, stable load, small fluctuation and strong predictability. my country has a long coastline and huge tidal energy reserves in coastal waters, so it has received widespread attention. [0003] The development and utilization of ti...
