Folding vertical shaft tidal power generation device

Abstract

The invention discloses a folding vertical shaft tidal power generation device, and belongs to the technical field of tidal power generation. In the folding vertical shaft tidal power generation device, blades are connected to a main shaft by connecting rods; a tidal current which acts on the blades can rotate the main shaft; and the main shaft drives a generator for generating power through a speed-increasing gearbox and a universal joint. The connecting rods, the blades and the main shaft of the power generation device respectively adopt a folding structure locked by a locking mechanism, two connecting rods and one blade form an impeller assembly, circumferentially and uniformly distributed impeller assemblies are fixedly connected with the main shaft through the larger ends of the connecting rods, and sliders at the smaller ends of the connecting rods are embedded in chutes of the blades; the speed-increasing gearbox is fixed on a top plate of a protective cover through a support, and the generator is fixed on the inner side of the top plate of the protective cover; and the protective cover also adopts a folding structure, and is fixed on a cement foundation through a base. The power generation device can reduce the volume of the whole device, facilitate the transport, avoid disassembly and assembly of various components, and reduce the seabed installation cost by over 50 percent than the original cost through effective folding.

Description

technical field [0001] The invention relates to a foldable vertical 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, compared with the use of tidal energy, tid...
