Wind-driven generator based on spring characteristic to adjust wind mouth, wind quantity and wind speed

Abstract

The invention discloses a wind-driven generator based on the spring characteristic to adjust a wind mouth, the wind quantity and the wind speed. The wind-driven generator structurally comprises a windspeed adjusting device, a wind-driven generator body and a high-strength supporting rack, wherein the bottom face of the wind-driven generator body is vertically connected with the high-strength supporting rack, and the wind-driven generator body is provided with the wind speed adjusting device. Compared with the prior art, the wind-driven generator based on the spring characteristic to adjust the wind mouth, the wind quantity and the wind speed has the beneficial effects that the size of a wind inlet mouth is adjusted utilizing the characteristic of being capable of equidistantly shrinks from one ring to another of springs, so that the wind inlet quantity is adjusted, and then control of the wind speed is realized, the wind speed is made to be not much more than the rated wind speed to avoid emergency brake failure of the wind-driven generator, so that appearance of the wind-driven generator coasters phenomenon is prevented, wind-driven generator damage can be avoided to a large extent, and minitype wind-driven generators on the coast are made to be also capable of running to generate electricity utilizing the wind energy during the summer typhoon high-incidence season.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a wind power generator for adjusting the air volume and wind speed of a tuyere based on spring characteristics. Background technique [0002] New energy includes solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy, etc. Wind generators are electrical equipment that convert wind energy into mechanical energy, and mechanical energy into electrical energy. The speed of rotation is increased through the speed reducer to promote the generator to generate electricity. When the wind speed is very low, the wind turbine rotor will remain still. When the cut-in wind speed is reached, the rotor will start to rotate and the traction generator will Power generation, at this time the output power is proportional to the wind; when the wind speed reaches the rated wind speed, the wind turbine will output its rated power; when t...

Problems solved by technology

[0003] Summer is the season with a high frequency of typhoons. For small wind turbines on the seashore, the wind is relatively easy to blow and the wind is strong, and the typhoon will make the wind speed far exceed the rated wind speed, causing the emergency brake of the wind turbine to fail. As a result, the phenomenon of speeding of wind turbines occurs extremely, and wind turbines are easily damaged.
