Problems solved by technology

This causes the fixed cables on the tower to follow the twisting of the nacelle, and in severe cases, it will cause the twisted cables of high-power fans to fail, or even break the cables
[0003] In order to prevent the twisted cable failure of high-power fans, two solutions are usually adopted. First, the cable uses anti-twisted cables, but the requirements for cable quality are relatively high, and the cost is too high
Second, design an automatic twisting mechanical device, but there are higher requirements for the cost and complexity of the device

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Please refer to figure 1 , the figure shows a high-power fan automatic uncable device, including: tower fixed ring 1, uncable spring 2, movable cable hoop 3 and tower cable 4; where:

[0015] The tower fixed ring 1 and the movable cable ferrule 3 are installed concentrically, and there are 4 uncable springs 2, which are arranged radially and concentrically and evenly distributed between the tower fixed ring 1 and the movable cable ferrule 3, and the movable cable ferrule 3. Tower cables 4 are sheathed inside.

[0016] The displacement of each uncable spring 2 is S 1 , S 2 , S 3 and S 4 , where S 1 , S 3 In the same straight line direction, S ,2 , S 4 In the same straight line direction, two straight lines are perpendicular to each other.

[0017] The elastic deformation coefficient of each uncable spring 2 is K, and the resultant force of the reaction force...

Abstract

The invention discloses an automatic cable untwisting device for a high-power fan. The automatic cable untwisting device comprises a tower fixing ring, a cable untwisting spring, a movable cable hoop and a tower cable. The automatic cable untwisting device for the high-power fan has the advantages of automatic and flexible cable untwisting, convenience in use, low cost and the like.

Description

technical field [0001] The invention belongs to the field of high-power fan manufacturing, and in particular relates to an automatic uncable device for a high-power fan in the transmission of the high-power fan. Background technique [0002] The electrical energy of high-power wind turbines is output to the power grid by cables fixedly laid on the tower. Due to the need for high-power wind turbines to capture wind energy, the nacelle must perform yaw movements according to the wind direction to ensure maximum capture of wind energy. This has caused the fixed cables on the tower to twist along with the nacelle, and in severe cases, it will cause the twisted cables of high-power fans to fail, or even break the cables. [0003] In order to prevent the twisted cable failure of high-power fans, two solutions are usually adopted. First, the cable uses anti-twisted cables, but the requirements for cable quality are relatively high, and the cost is relatively high. Second, design a...
