Embodiment 1

[0012] The hub of the wind power generator of the present invention connects the wires of the blades to the bracket, and the vertical column 2 is fixed vertically on the manhole cover plate 1 in the blade. The wire 4 of the hub wiring board 3 is wound on the column 2 and then connected to the fan blade wiring board.

Embodiment 2

[0014] The hub of the wind power generator of the present invention is connected with the blade lead wire, and the center of the manhole cover plate 1 in the blade is vertically fixed with a column 2, and the length of the column 2 is less than the distance from the manhole cover plate 1 to the hub terminal plate 3, The wire 4 connected to the hub wiring board 3 is wound on the column 2 and then connected to the fan blade wiring board. Wherein, the wire 4 wound on the column 2 is fixed by the binding band 6;

Embodiment 3

[0016] The hub of the wind power generator of the present invention connects bracket with the blade wire, is to be fixed with crossbeam 5 on the center of the manhole cover plate 1 in the blade, and crossbeam 5 also can be replaced with circular sheet. Column 2 and beam 5 are vertically connected into one body, the length of column 2 is less than the distance from the manhole cover to the hub terminal board 3, the wire 4 connected to the hub terminal board 3 is wound on the column 2, and then connected to the fan blade terminal board superior. Wherein, the wire 4 wound on the column 2 is fixed by the binding band 6;

Abstract

The invention relates to a hub / blade wire connecting bracket of an aerogenerator. An upright post is perpendicularly fixed in the center of a manhole cover plate in a blade, and a wire connected to a hub wiring board is wound around the upright post and then is connected to a fan blade wiring board. The wire wound on the upright post is fixed by a strapping tape; and the end of the upright post and the wire are fixed together through a heat shrinkable sleeve, and the hub wiring board and the wire are fixed together through another heat shrinkable sleeve. The invention has the advantages of reasonable design and simple structure. Since the lightning protection wire is relatively fixed by the bracket, the invention effectively solves the problem of wire deformation when the wire rotates along with the blades, overcomes the defects of lightning protection wire rupture and frequent maintenance, prolongs the repair cycle and enhances the production efficiency.

Description

technical field [0001] The invention relates to a bracket for connecting a hub of a wind power generator and a lead wire of a blade. Background technique [0002] In the existing wind power generator, the lightning protection terminal board on the blade is connected with the lightning protection terminal board on the hub by wires, so as to solve the lightning protection problem between the blade and the hub. However, the existing lightning protection wires rotate together with the blades, which will deform the wires over time, resulting in poor fatigue resistance and breakage of the wires, making the lightning protection wires useless and requiring frequent maintenance. If the broken wires are not repaired in time, It is very easy to damage other parts in the hub. Contents of the invention [0003] The invention aims at overcoming the disadvantages of the prior art, and provides a support for connecting the hub of the wind power generator and the wires of the blades.
