Sliding type wind energy density increasing device

Abstract

The invention discloses a sliding type wind energy density increasing device, which is characterized by comprising a central tube, an air collecting tube and a sliding mechanism, wherein the central tube is arranged outside a wind driven generator in a sleeving manner, the small port end of the wind collecting tube is fixedly connected with the front end of the central tube, and the wind collecting tube is fixedly connected with the sliding mechanism. The invention has the advantages that the sliding type wind energy density increasing device is mounted on the wind driven generator; the intensity of the wind energy blown to the wind driven generator is increased; the wind speed is improved; the wind driven generator can also operate under the condition of lower natural wind speed; when the natural wind speed is higher, the wind collecting tube and the central tube move backwards along a guide rail since the wind driven generator is fixed; the large port end of the wind collecting tube is close to the wind driven generator, as a result, the effect of the wind collecting tube is weakened under the condition of higher natural wind speed; the wind driven generator can also operate normally under the condition of higher natural wind speed; and the application wind speed range of the wind driven generator is enlarged.

Description

technical field [0001] The invention relates to a wind collecting device in the field of wind power generation, in particular to a sliding type wind energy density increasing device. Background technique [0002] Wind generator is one of the power generation devices, and its application is relatively wide. However, the current wind generator is greatly affected by the wind speed. When the natural wind speed is relatively small, the wind generator cannot start normally, and when the natural wind speed is relatively high, in order to protect the wind generator, the wind generator will be in a protection state and stop working. , therefore, the applicable wind speed range of the wind turbine is relatively narrow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sliding wind energy density increasing device that can expand the applicable wind speed range of the wind power generator. [0004] The technical solutio...
