Problems solved by technology

[0002] There is an electrical control cabinet inside the wind turbine dome, and the pitch angle and yaw of the blades are adjusted by a special motor to adapt to changes in wind direction and wind force. Maintenance is difficult and even increasingly mysterious.
In particular, the vertical tower is subject to enormous bending force and high cost, which seriously restricts the development of wind power

Embodiment Construction

[0012] The wind power generation device of the present invention is composed of a fan blade 1, a central shaft of a fan, a hub 2, a gearbox, a generator, a fairing 3 and a novel tower 10, and the like.

[0013] The tower frame 10 of the present invention is composed of two parts, a rotating part and a limiting part. The limit portion of the giant wind power plant tower 10 is mainly a reinforced concrete member, which can be a straight cylinder with equal inner diameter, and anchors such as umbilical cables 9 are added in the circumferential direction.

[0014] The main body of the limiting part of the tower 10 of the household small-scale wind power generation device of the present invention is a hollow column made of such materials as steel pipe and channel steel. The lower end of the column is clamped on the reinforced concrete foundation, and several casing cables are arranged downward from the top. Such as limit accessories. During maintenance, the hollow column can be ti...

Abstract

The invention relates to a novel wind power generation device. The novel wind power generation device is composed of fan blades, a fan central shaft, a hub, a transmission, a power generator, a fairing, a novel tower and the like. A bent pipe rod and a bending head which can pitch backwards along with intensity changes of strong winds are arranged on a rotating part of the tower. The novel wind power generation device is simple in structure, naturally adaptive to changes of the heading direction and the wind intensity, extremely beneficial to utilization of natural wind power, extremely beneficial to great reduction of the manufacturing cost, and extremely beneficial to wind power development to bright benefits to the public.

Description

technical field [0001] The invention belongs to the technical field of wind power generation. Background technique [0002] Currently, there is an electrical control cabinet inside the dome of the wind turbine. The pitch angle of the blades and the yaw degree are adjusted by a special motor to adapt to changes in wind direction and wind force. Maintenance is difficult and even increasingly mysterious. In particular, the vertical tower suffers from enormous bending force and high cost, which seriously restricts the development of wind power. Contents of the invention [0003] The wind power generation device of the present invention is composed of fan blades, fan central shaft, wheel hub, gearbox, generator, fairing and new tower frame. [0004] The tower frame of the present invention is composed of two parts, a rotating part and a limiting part. The limit part of the giant wind power plant tower is mainly made of reinforced concrete members, which can be a straight cyli...
