On the other hand, the vibration generated at the resonance point when the large blade moves is enough to destroy the fan
Large blades that are too long are difficult and expensive to manufacture, install and transport

Embodiment Construction

[0012] specific implementation plan

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described

[0014] from figure 1 It can be seen from the figure that the wind wheel of a wind energy power plant according to the present invention is composed of a unit wind wheel 5a, a unit wind wheel 5b and a vertical shaft 1, and the shaft sleeve 2 is sleeved on the shaft sleeve 2. A cantilever 3 is connected, and a blade 4 is connected to the cantilever 3. The bushing 2, the cantilever 3 and the blade 4 form a unit wind wheel 5, and the unit wind wheel 5a and the unit wind wheel 5b are mounted on the vertical shaft 1 in series . There can be 2 to 50 unit wind wheels 5; the unit wind wheels 5 of each layer can be the same or different. A unit wind wheel 5 can have 2 to 16 cantilevers 3 . The included angle between the cantilevers 3 of different units of the wind wheel 5 constituting the wind wheel can be in the range of 0 to 1...

Abstract

The invention discloses a windwheel of large-scale wind power propulsion plant, which consists of windwheel and upright shaft, wherein the axle sleeve is covered on the upright shaft; the axle sleeve connects to cantilever; the cantilever links up to blade; a unit windwheel is composed of axle sleeve, cantilever and blade; the unit windwheel is installed on the upright shaft in short transverse of the upright shaft; at least two units windwheel are installed on the upright shaft. The invention reduces the stress of the windwheel blade, which reduces the cost.

Description

technical field [0001] The invention relates to a wind rotor of a large-scale wind power device, in particular to a wind rotor of a large vertical shaft wind power device. technical background [0002] Since the enlargement of wind turbines is the main way for grid-connected wind turbines to reduce power generation costs, megawatt-scale wind turbines are currently the mainstream models. However, due to the limitation of the blade structure and the weight of the manufacturing materials, the limit capacity of the horizontal axis wind turbine is 5 megawatts. To develop larger wind turbines, people turn their attention to vertical shaft wind turbines. Although the structural capacity of the vertical axis wind turbine can reach 100 megawatts, its blades need to be cantilevered to form a wind rotor. Therefore, as the blades of the vertical axis fan increase, the cantilever will also increase and the weight will also increase. This is the main factor affecting the efficiency and ...
