Stall speed protection device for wind energy power generation in new energy

Abstract

The invention relates to the solar energy or other clean energy relevance technical field, and discloses a stall speed protection device for wind energy power generation in new energy. The stall speedprotection device comprises a first shell, wherein a fixed ring is fixedly connected to the interior of the first shell; and a coil is fixedly connected to the outer part of the fixed ring. Through interaction among all structures of the device, when stall of a power generation rotary shaft occurs, the device can automatically stop rotation of the rotary shaft, and thus, overload of the power ofa power generator unit can be avoided, internal parts of a power generator can be reduced, and over-high temperature in the power generator unit also can be avoided, and therefore, the probability offire disasters can be effectively reduced; and when the stall of the rotary shaft occurs, a second rotating vane also can be automatically put down through the device, and thus, loss of the rotating vane under heavier external wind power also can be avoided, the life and property safety of people can be protected more effectively, and meanwhile, the safety of a wind-power power generation structure in the new energy is higher.

Description

technical field [0001] The invention relates to the technical field related to solar energy or other clean energy sources, in particular to a stall protection device for wind power generation in new energy sources. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Because wind energy is a clean and pollution-free renewable energy source, wind power generation is widely used by people. However, there are still many problems in current wind power generation, because the current The power of the generator assembly machine in the wind power generation device is limited, so today's wind power generation equipment has certain restrictions on the rotation speed of the drive shaft and fan blades, but the existing wind power generation equipment does not have the function of stall protection. When the external wind force When it is larger, it will make the fan blades rotate too fast, which may cause the power o...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stall protection device for wind power generation in new energy sources, which has the advantages of automatically performing stall protection when the generator shaft stalls, and has the advantages of better safety, and solves the problems that still exist in the current wind power generation More problems, because the power of the generator assembly machine in the current wind power generation device is limited, so the current wind power generation equipment has certain restrictions on the rotation speed of the drive shaft and the fan blade, but the existing wind power generation equipment does not have a stall The protection function, when the external wind is strong, the fan blades will rotate too fast, which may cause the power overload of the generator set, which will cause serious wear and tear on the internal parts of the wind power generation equipment, and this will also A fire may occur due to the excessive heat inside the generator set, which will threaten people's lives and property safety, and at the same time, it will also make the wind power generation equipment have a greater safety hazard
