Shaft-hanged type windmill

Abstract

The present invention discloses one kind of vertical shaft type wind mill, and aims at providing one kind of vertical shaft type wind mill capable of utilizing wind energy in different directions, and with great momentum, simple structure, high durability, high safety, easy maintenance and low cost. The vertical shaft type wind mill consists of mainly vertical shaft, wind blades and wind guiding frame, and may be used widely in wind electric power generation and other wind energy utilizing fields.

Description

technical field [0001] The invention relates to a windmill, in particular to a vertical axis windmill for wind power generators. Background technique [0002] At present, the main shaft of most windmills is suspended in parallel and can only use wind energy in one direction. Therefore, wind energy cannot be used in multiple directions, and the momentum obtained is not large enough. As the wind direction changes, the orientation of the windmill must be changed with the help of wind direction sensing devices and steering devices. , so the structure is complex, not durable, unsafe, difficult to maintain, and high in cost. Chinese Patent Publication No. CN2088607U, the date of disclosure is November 13, 1991, and the title is "wind-collecting vertical-axis windmill", which discloses a kind of wind-collecting vertical-axis windmill. The device consists of three main fan blades, three auxiliary fan blades, an upper circular cover plate, a lower bottom circula...

Chinese Patent Publication No. CN2088607U, the date of disclosure is November 13, 1991, and the title is "wind-collecting vertical-axis windmill", which discloses a kind of wind-collecting vertical-axis windmill. The device consists of three main fan blades, three auxiliary fan blades, an upper circular cover plate, a lower bottom circular plate, three speed regulating rods, and six speed regulating springs. The air collecting device is fixed on the vertical shaft, and the vertical shaft is fixed on the On the bracket, that is, the entire air collecting device is suspended on the bracket through the vertical shaft, and the three auxiliary fan blades are respectively controlled by the activities of the upper and lower three speed regulating levers and three speed regulating springs. The entire air collecting device drives the vertical shaft to rotate together, and the windmill Although wind energy can be utilized in multiple directions and momentum has been improved, it is still not perfect, the structure is more complicated, not durable, unsafe, difficult to maintain, and high in cost. Therefore, the prior art has the following deficiencies: it cannot fully utilize wind energy in multiple directions ; Momentum is not large enough; the structure is complex, not durable, unsafe, difficult to maintain, high cost
