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 shaft brake, 2 high-speed shaft brake, 3 yaw brake, hydraulic brake speed regulation, etc.
The friction and wear of brakes are large, but the error of speed regulation is also large. It depends on electrical appliances such as grid connection and voltage stabilization and transformation to adjust voltage and computer control management. The structure is complex and there are many wearing parts.
So far, wind farms and ocean current power generation have not been profitable, and they cannot generate electricity off-grid independently. Existing small wind turbines rely on diesel vehicles or batteries to generate electricity off-grid, but they are also unprofitable. receipt and other defects

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...
