Abstract

The invention belongs to development technical field of ocean energy in renewable energy sources, and relates to an ultra-low rotating speed weak tidal current energy efficient power generation apparatus. A generator rotor is equipped with a weight-balancing part and a one-way transmission mechanism; the mechanical energy output by a main shaft is converted into gravitational potential energy for the weigh-balancing part of the generator rotor; the generator rotor and the weigh-balancing part rapidly fall off rotatably in a manner similar to free falling body; and when the speed achieves the highest level, pulse type power generation is realized through coils. The ultra-low rotating speed tidal current energy pulse generator is applicable to ultra-low rotating speed weak tidal current at the speed of 0.3m / s or below, which is high in power generation efficiency, long in power generation time, wide in applicable range, and suitable for 85% of sea areas of China; and meanwhile, the ultra-low rotating speed tidal current energy pulse generator is simple in structure, high in mechanical strength, reliable in performance, light in weight, easy to install, wide in applicable area, capable of manufacturing different specifications according to different power requirements, low in cost, long in service life, small in size, and resistant to sea water corrosion.

Description

technical field [0001] The invention belongs to the technical field of ocean energy development in renewable energy, and relates to a device for efficiently generating electricity by using ultra-low-speed weak tidal current energy in the ocean. Background technique [0002] The so-called ocean current mainly refers to the relatively stable flow in submarine channels and straits. The so-called tidal current mainly refers to the regular seawater flow caused by tides. The ocean current and tidal current are mixed together, and tidal current energy accounts for the main part. , Tidal current power generation is a technology that uses the kinetic energy of ocean currents to generate electricity. Generally, there is no need to build a dam, and the water turbine unit generates electricity. The energy of the tidal current is proportional to the square of the flow velocity and the flow rate. [0003] The main way to use tidal current energy is to generate electricity. Its princip...
