Efficient three-wheeled telescopic folding horizontal-shaft tidal current energy generating equipment

Abstract

The invention discloses efficient three-wheeled telescopic folding horizontal-shaft tidal current energy generating equipment, belonging to the technical field of tidal current energy generation. The generating equipment is respectively connected with steering knuckles at two sides of a connection body through a telescopic folding cross arm; a generator and a speed-increasing gearbox are respectively fixed at one side of one steering knuckle; a small impeller is connected with the speed-increasing gearbox through a telescopic folding connection rod; the lower side of the steering knuckle is equipped with a rudder which can ensure the tidal current direction is directly opposite to the impeller; the top of the connection body is equipped with the other steering knuckle, and the generator and the speed-increasing gearbox are fixed at one side of the steering knuckle; and a large impeller is connected with the speed-increasing gearbox through the telescopic folding connection rod. The generating equipment is simultaneously provided with three hydro-turbine units for power generation, thus improving generating efficiency of single generating equipment; and main components adopt telescopic folding structures to achieve effective telescoping and folding, thus reducing volume of the whole equipment, facilitating transportation, avoiding disassembly and assembly among the components, reducing submarine installation cost by over 50%, and prolonging service life of a hydro-turbine by over 5 years.

Description

technical field [0001] The invention relates to a three-wheel high-efficiency telescopic and folding horizontal-axis tidal current energy generating device, which belongs to the technical field of utilizing tidal current energy to generate electricity. Background technique [0002] As a clean and renewable energy source, ocean energy is not only rich in resources, but also has little impact on the environment. At present, the theoretical total amount of renewable ocean energy resources in the world is 766,000GW, and the development prospects are very promising. my country has a long coastline and a vast sea area, and has abundant ocean energy reserves. The exploitable ocean energy resources include: tidal current energy, tidal energy and wave energy, etc. Among them, the theoretical average power of tidal current energy is 13940MW. Due to its strong predictability, tidal current energy has greater advantages than wave energy in stably providing electricity. At the same time...
