Problems solved by technology

However, most of the small wind turbines currently on the market have the disadvantage of poor performance when starting at low speeds, so they are not suitable for installation in places with relatively low wind speeds, such as urban or residential areas

Embodiment Construction

[0063] figure 1 A perspective view illustrating a wind drive device according to an embodiment of the present invention, and figure 2 for figure 1Front view of the medium wind drive unit. The wind driving device 10 includes a base frame 11 , a rotating shaft 14 , multiple sets of blade brackets 12 and multiple blades 13 . The rotating shaft 14 is fixed on a bearing 15 or a roller (not shown) of the base frame 11 , and can freely rotate around its own shaft centerline. Each set of blade brackets 12 includes a plurality of support columns 121 extending radially along the rotating shaft 14, that is, a plurality of support columns 121 are radially arranged similar to spokes, and one end of the plurality of support columns 121 is connected to the The rotating shaft 14 and the other end are connected to the blades 13 .

[0064] Each of the blades 13 includes two symmetrically arranged wing portions 131 , and it is obvious that the two wing portions 131 are connected to a centra...

Abstract

The invention discloses a wind-driven device which comprises a base frame, a rotary shaft, a plurality of blade brackets and a plurality of blades. The rotary shaft is fixed on the base frame and can rotate around the axial central line of the rotary shaft; each blade bracket is connected with the rotary shaft and the plurality of blades; and each blade comprises two wing parts which are configurated symmetrically, and the wing shafts of the two wing parts are respectively provided with an acute included angle relative to the axial central line of the rotary shaft respectively.

Description

technical field [0001] The present invention relates to a wind turbine, in particular to a wind driving device and its module. Background technique [0002] In recent years, under the global trend of increasing awareness of environmental protection and rising oil prices, the market for renewable energy such as wind power has begun to grow rapidly. A wind turbine uses a wind turbine to convert wind energy into mechanical energy, which is then converted into electrical energy using a generator. According to the current technology, power generation can be started at a breeze speed of about 3 meters per second, and the output power can be adjusted for commercial AC power or converted into DC power for storage in batteries. [0003] U.S. Patent No. US7,132,760 "Wind Turbine Device" proposes a wind power generation system in which the vertical axis wind turbine is placed and operated in a horizontal manner. The advantages of low cost and high safety are suitable for direct insta...
