Flow guide reaction type double-rotor tidal current energy water turbine

Abstract

The invention aims to provide a flow guide reaction type double-rotor tidal current energy water turbine. The water turbine comprises a flow guide cover, a shell, an impeller, a speed increasing gearbox, and a generator; the flow guide cover is connected with the shell through a flow guide cover support; the impeller, the speed increasing gearbox, and the generator are arranged in the shell; the impeller comprises an upstream impeller and a downstream impeller; the upstream impeller and the downstream impeller are provided with blades; the speed increasing gearbox comprises an upstream speed increasing gearbox and a downstream speed increasing gearbox; the upstream impeller is connected with an input shaft of the upstream speed increasing gearbox; the downstream impeller is connected with an input shaft of the downstream speed increasing gearbox; an output shaft of the upstream speed increasing gearbox is connected with an outer rotor of the generator; an output shaft of the downstream speed increasing gearbox is connected with an inner rotator of the generator; and the inner rotator of the generator is arranged in the outer rotor of the generator. The water turbine is high in energy utilization rate, and can fully utilize the energy of incoming flow and effectively increase the relative rotation speed of the rotors of the generator so as to improve generated energy.

Description

technical field [0001] The invention relates to a hydraulic turbine in the mechanical technical field of hydraulic power generation equipment. Background technique [0002] Ocean tidal current energy is a kind of renewable energy, and the development of ocean tidal current energy is of great significance to alleviate energy and environmental problems. Tidal current energy power generation technology is a part of hydroelectric power generation technology. It uses the periodic fluctuations of seawater to generate fluid potential energy to drive the power generation equipment to operate, thereby generating electric energy. The hydraulic turbine is used as a device for obtaining tidal current energy. , the history of its formation and development is relatively short. It was mainly developed at the end of the last century and was developed by some European and American countries. Its basic structure mainly evolved from the fan structure, which is called "underwater windmill". ...
