Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0022] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0023] Such as figure 1 , 2 As shown, the present invention provides a wind power generating set, which can reduce the weight of the blades, avoid resonance during rotation, and avoid vibration of the generator when resonance occurs.

[0024] In order to achieve these objects and other advantages according to the present invention, a wind power generating set is provided, which has a blade 1 rotated by the wind, a generator 2 driven by the rotation of the blade 1 and generating electricity, the blade 1 comprising a blade body 100 comprising:

[0025] Blade leading edge 101; it...

Abstract

The invention discloses a wind generating set which comprises blades driven to rotate by wind and a power generator driven by rotation of the blades to generate power. Each blade comprises a blade body. Each blade body comprises a blade body front edge, a blade body main beam and a blade body wing type region. Each blade body front edge is of a hollow structure limited by an inner shell and an outer shell, sealed silica gel bag bodies extend from the outer surface of each inner shell to the inner surface of the corresponding outer shell, and each silica gel bag body contains liquid with the volume not larger than one half of the size of the bag body. Each blade body wing type region comprises an upper elastic skin located on a pressure surface and a lower elastic skin located on a suction surface. Each upper elastic skin and each lower elastic skin both comprise a sheet located at the inner layer, a base body located at the middle layer and ultrahigh-strength polyethylene fiber fabric located at the outer layer, and the hollow structure of each blade body wing type region is limited by the corresponding sheets. According to the wind generating set, the weight of the blades can be lowered, resonance generated in the rotating process is avoided, and meanwhile the condition that the power generator vibrates under the resonance condition is avoided.

Description

technical field [0001] The present invention relates to equipment for generating and storing wind power, and more particularly, to an improved configuration of blades of a wind power generating set. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, and is mainly composed of blades, generators, mechanical components and electrical components. However, at present, the FRP blades of small and medium-sized kilowatt-class wind turbines still have some deficiencies such as heavy weight, low strength, and poor impact resistance. Especially when the wind turbine is running, the blades of the wind turbine will vibrate due to the effect of wind load and the elastic structure of the blade itself. Vibration is the main cause of material fatigue, and when the vibration amplitude is too large, it will affect the safety of wind turbines. Contents of the invention [0003] It is an object of the present invention to solve at least...
