Embodiment Construction

[0026] Refer to attached picture Figures 1 to 3 As shown, the adjustable wind turbine cable protection device of the present invention includes a cable fastening clip 7 and an adjustment mechanism that drives the cable fastening clip 7 to move up and down. The adjustment mechanism includes at least three vertical adjustment ropes arranged in parallel and respectively connected to them The beam 2, the vertical adjustment rope can be adjusted up and down inside the wind turbine tower, one end of the beam 2 is fixedly connected to the vertical adjustment rope, and the other end is connected to the outside of the cable clamp 7.

[0027] In the present embodiment, the vertical adjustment rope adopts the steel wire rope 1. The wire rope 1 can be adjusted up and down inside the wind turbine tower, and specifically set above the twisted cable platform inside the wind turbine tower, then the wire rope 1 hangs the cable protection device above the twisted cable platform. 1, the cable ...

Abstract

The invention discloses an adjustable wind turbine generator cable protection device. The adjustable wind turbine generator cable protection device comprises a cable fastening clamp and an adjusting mechanism for driving the cable fastening clamp to move up and down; and the adjusting mechanism comprises at least three parallel vertical adjusting ropes and transverse beams correspondingly connected with the vertical adjusting ropes, the vertical adjusting ropes are arranged inside a wind turbine generator tower barrel in a vertically-adjusted manner, one end of each transverse beam is fixedly connected with the corresponding vertical adjusting rope, and the other end of each transverse beam is fixedly connected with the outer side of the cable fastening clamp. The cable fastening clamp comprises two detachably-connected fastening plates, and a closed zone used for fastening cables can be defined through the two fastening plates. According to the adjustable wind turbine generator cable protection device, through the vertical adjusting ropes capable of being adjusted vertically, the cable protection device can descend to a cable twisting platform when needed, high-air operation risks in the device maintaining process are avoided, and operation safety of operation and maintenance persons is improved. The cable fastening clamp is designed to be of a split type structure, and therefore the cable protection device is flexible and convenient to install.

Description

technical field [0001] The invention relates to a cable protection device, in particular to an adjustable wind turbine cable protection device. Background technique [0002] During the yaw process of the wind turbine, the cables hanging from the nacelle are twisted inside the tower, and the cables wear and collide with each other. When the wind speed is high, the cables may even hit the tower and internal accessories. The fatigue life of the tower and internal accessories will be affected. Therefore, in order to protect the cables, a cable protection device is generally installed between the yaw platform and the twisted cable platform. However, since the existing cable protection device is located several meters above the twisted cable platform, on-site maintenance needs to be carried out at high altitudes, which is poor in safety and needs to be carried out in The installation is completed before the tower is hoisted, and the operation flexibility is not good.
