Wind power generation equipment with speed limiting mechanism

Abstract

The invention relates to the field of wind power generation equipment, in particular to wind power generation equipment with a speed limiting mechanism. The wind power generation equipment comprises a tower, a rotating cabin is mounted at the top of the tower, a transmission shaft is horizontally mounted in the middle of the rotating cabin, second blades is mounted at one end, outside the rotating cabin, of the transmission shaft, and first blades are arranged between the second blades and the rotating cabin. The first blades are connected with the transmission shaft. A supporting mechanism is arranged on the outer wall of the side, close to the first blades, of the rotating cabin. A spring triggering mechanism is further arranged on the outer wall of the side, close to the first blades, of the rotating cabin. According to the wind power generation equipment with the speed limiting mechanism, the problems that common wind power generation equipment generally has only one set of blades, the angles of the blades are fixed, when the wind speed is suddenly increased within a short time, the rotating speed of the blades is likely to be increased suddenly, consequently the temperature in a rotating cabin is too high, electromagnetic braking or mechanical braking is generally adopted when the blades decelerate, and when the wind speed is kept high for a long time, the temperature in the cabin is more likely to be too high due to mechanical braking are solved.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a wind power generation device with a speed limiting mechanism. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. The use of wind power to generate electricity is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries all over the world. . [0003] Ordinary wind power equipment generally only has one set of blades, and the angle of the blades is fixed and cannot be adjusted. When the wind speed suddenly increases in a short period of time, the speed of the blades is likely to increase suddenly, which will cause the temperature in the rotating cabin to be too high. Electromagnetic is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a wind power generation device with a speed limiting mechanism to solve the problem that ordinary wind power generation devices generally have only one set of blades, and the angle of the blades is fixed and cannot be adjusted. When the wind speed suddenly increases in a short period of time, the speed of the blades is likely to increase suddenly. , resulting in too high temperature in the cabin, and electromagnetic brakes or mechanical brakes are generally used to decelerate the blades; when the wind speed maintains a high wind speed for a long time, electromagnetic brakes or mechanical brakes are more likely to cause excessive temperature in the cabin
