Wind energy density increasing device

Abstract

The invention discloses a wind energy density increasing device. The wind energy density increasing device is characterized by comprising a center pipe and a wind collecting pipe, wherein the center pipe and the wind collecting pipe are fixedly arranged, the wind collecting pipe is in a round table shape, the center pipe is sheathed on the outside of a wind generator, the small end of the wind collecting pipe is fixedly connected with the front end of the center pipe, and the circumferential surface of the wind collecting pipe is hinged with at least two opening baffle plates. The wind energy density increasing device has the advantages that the wind energy density increasing device is arranged on the wind generator, so the density of the wind energy of the wind blowing towards the wind generator can be increased, the wind speed is improved, and the wind generator can also normally work when the natural wind speed is lower; when the natural wind speed is higher, the opening baffle plates hinged on the wind collecting pipe are blown up to form an opening, then the wind is blown out through the opening, and the speed of the wind blowing towards the wind generator is reduced, so the wind generator can also normally work when the natural wind speed is higher; and the change of the wind speed is uniform, and meanwhile, the wind speed application range of the wind generator is expanded.

Description

technical field [0001] The invention relates to a wind collecting device in the field of wind power generation, in particular to a 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 wind energy density increasing device that can expand the applicable wind speed range of the wind power generator. [0004] The technical solution adopted by the pres...
