Problems solved by technology

But so far, the utilization efficiency of wind energy is still very low, because coal-fired fuel energy is currently used, and there is no idea that coal-fired fuel energy will bring serious pollution, resulting in global air pollution and global warming
At present, the known wind power generation or ocean current power generation has high power generation cost, low blade utilization efficiency, and difficult speed regulation function. At present, the speed regulation function and system structure used in wind power generation basically have: pumping station, oil cylinder, filter, servo oil cylinder , proportional valve, yaw gear, yaw motor, hydraulic brake has three parts: 1 low-speed

Abstract

The wind electric and sea current power generation vane speed regulator has tower seat, fixed cross beam, machine room, bearing, rotation shaft, movable shaft fixer, fixed shaft seat, frame cross beam, speed regulating box, moving body, vane shaft, vanes, etc. connected successively. There are automatic speed regulating structure on the frame cross beam, conveying part on the speed regulating structure and executing part on the vane shaft. The present invention has the vanes rotating in designed direction to drive the power generator to generate electric power and has the moving body and vanes to complete automatic speed regulation. The present invention has wide stepless speed regulating range and high speed regulating precision as well as high power and efficiency.

Description

Technical field: [0001] The invention relates to a kind of safety device application which can obtain wind power generation and sea current (belonging to water flow or seawater flow of tidal fluctuation) power generation, and an automatic centrifugal speed regulating mechanism to keep the rotation speed stable, especially relates to air flow and organic Wherever water flows, power generation can be installed, especially to solve the current energy pollution and energy shortage. Background technique: [0002] In the centuries BC, the people of our country used wind power to lift water, irrigate, grind flour, pound rice, and use sails to propel ships forward. At that time, vertical axis wind turbines were also popular, and they are still in use today. But so far, the efficiency of wind energy utilization is still very low, because coal and fuel oil are currently used for energy, and there is no idea that coal and fuel energy will bring serious pollution, resulting in global a...
