A vertical axis wind power generator

Abstract

A vertical-shaft wind power generation device comprises a first blade group composed of blades, a rotation part for the blades to rotate, connecting bodies for installing the blades on the rotation part movably and a power generator. Under the wind action, the blades rotate around the rotation part to drive the power generator to generate electricity, and the rotation part is an annular track. The blades of the vertical-shaft wind power generation device are supported on the annular track and rotate around the annular track, and a mode that the blades are supported on a vertical shaft to rotate in the prior art is not adopted, so that the vertical-shaft wind power generation device can be manufactured to be large. On the one hand, improvement of generating efficiency of the wind power generation device is facilitated; on the other hand, an actual blade operation space is an annular region ranging from the blades to the annular track, and any obstacle is not arranged on the inner side of the annular track, so that the wind power generation device can be conveniently installed on the periphery of several buildings in a sleeved mode and can be integrated with the buildings well, and an installing and using range of the wind power generation device is effectively widened.

Description

technical field [0001] The invention relates to the technical field of wind power generation devices, in particular to a vertical axis wind power generation device with a new structure. Background technique [0002] Most of the vertical axis wind power generation devices in the prior art are as figure 1 As shown, it includes a blade 1, a connector, a vertical support shaft 3, and a generator 4. The blade 1 is movably installed on the vertical support shaft 3 through the connector, and can rotate around the vertical support shaft 3. The vertical support shaft 3 here is the rotating member for the blade 1 to rotate along it. The connecting body is composed of hubs 5, 6 and connectors 2. The hubs 5, 6 are set on the vertical support shaft 3, and the blade 1 is fixed on the hubs 5, 6 through the transverse or inclined connectors 2. The generator 4 is connected with the hub 6, and the blade 1 rotates under the wind force, and the generator 4 is driven by the hub 6 to generate e...

Problems solved by technology

[0003] The vertical axis wind power generation device with the above-mentioned structure has the disadvantage that the operating space is too large. The distance from the blade 1 to the vertical support shaft 3 is usually several meters. In this space, due to the installation of the connecting piece 2, it cannot be used at all, and it is difficult to communicate with it. Building integration, such as the open area that can only be installed on the top floor of the building, limits the installation range of wind power plants

In addition, since the blades of the wind power generation device in the prior art are all supported on the vertical support shaft at the center, this structure limits the scale of the existing wind power generation device, making it impossible to make the existing wind power generation device very big

This is because, if the structure of the wind power generation device in the prior art is made too large, the problem of eccentricity will be more serious, which will easily lead to safety problems

In addition, the vertical axis wind power generation device with the existing structure has relatively high requirements for wind speed, and it is difficult to capture energy at low wind speeds.
