A wind turbine cable anti-tangle fixing device

Abstract

This utility model discloses a wind turbine cable anti-tangle fixing device, relating to the technical field of wind turbine cable fixing devices. The device includes: a housing with cable routing holes at both its upper and lower ends; a retaining seat fixedly connected to the rear side of the housing; a matching retaining plate on the front side of the retaining seat; and a clamping assembly located on the front side of the housing's interior. The clamping assembly drives the movement of the retaining plate and includes a threaded sleeve with a lead screw threadedly connected internally. This invention solves the technical problems of existing fixing devices where the clamping force is uncontrollable. When using these devices, it is impossible to clamp and fix cables of different sizes flexibly, and the clamping force cannot be adjusted flexibly. Too loose a clamping force leads to cable displacement and entanglement, while too tight a clamping force compresses the cable insulation layer, accelerating cable aging and cracking, thus affecting the cable's service life.

Description

Technical Field

[0001] This utility model relates to the field of wind turbine cable fixing devices, and in particular to a wind turbine cable anti-tangle fixing device. Background Technology

[0002] The cable system of a wind turbine is the core carrier for energy transmission and signal control. Fixing devices are required when fixing the cables.

[0003] However, existing technologies have some problems: the clamping force of existing fixing devices cannot be controlled. When using the fixing devices, it is not possible to clamp and fix cables of different sizes, and the clamping force cannot be adjusted flexibly. If it is too loose, the cable will shift and become entangled; if it is too tight, the cable insulation layer will be squeezed, accelerating the aging and cracking of the cable and affecting its service life. Therefore, it is necessary to provide a wind turbine cable anti-entanglement fixing device to solve the above technical problems. Utility Model Content

[0004] This utility model provides a wind turbine cable anti-tangle fixing device, which solves the technical problems of existing fixing devices, such as the inability to control the clamping force, the inability to clamp and fix cables of different sizes, the inability to flexibly adjust the clamping force, the inability to loosen the clamping force causing cable displacement and entanglement, and the inability to squeeze the cable insulation layer due to excessive tightness, which accelerates cable aging and cracking and affects the service life of the cable.

[0005] To solve the above-mentioned technical problems, this utility model provides a wind turbine cable anti-tangle fixing device, comprising:

[0006] The outer casing has wiring holes at both its upper and lower ends. A card holder is fixedly connected to the rear side inside the outer casing, and a matching card plate is provided on the front side of the card holder.

[0007] A clamping assembly, located on the front side inside the housing, is used to drive the movement of the pallet.

[0008] Preferably, the clamping assembly includes a threaded sleeve, the inside of which is threadedly connected to a lead screw, the front end of which extends through the outer casing and is fixedly connected to a rotating wheel.

[0009] Preferably, a bearing seat is sleeved at the rear end of the lead screw, and the rear side of the bearing seat is fixedly connected to the front side of the clamping plate.

[0010] Preferably, guide blocks are fixedly connected to the upper and lower ends of both sides of the card plate, and guide rods are slidably connected inside the guide blocks, with the guide rods being longitudinally fixed inside the outer shell.

[0011] Preferably, a tension spring is sleeved on the rear side of the guide rod surface, the rear end of the tension spring is fixedly connected to the rear side inside the housing, and the front end of the tension spring is fixedly connected to the rear side of the guide block.

[0012] Preferably, the upper and lower ends of the rear sides of the outer casing are fixedly connected to assembly blocks, and the front side of the assembly blocks is provided with assembly holes.

[0013] Compared with related technologies, the wind turbine cable anti-tangle fixing device provided by this utility model has the following beneficial effects:

[0014] This utility model provides a wind turbine cable anti-winding fixing device. By setting the clamping component, rotating the wheel can drive the screw to move axially within the threaded sleeve, and then push the clamping plate to move smoothly close to the clamping seat through the bearing seat. The distance between the clamping plate and the clamping seat can be flexibly adjusted according to the cable diameter to achieve stepless adjustment of the clamping force. This avoids cable displacement and winding caused by excessive looseness, and also prevents damage to the insulation layer caused by excessive tightness.

[0015] This utility model provides a wind turbine cable anti-tangle fixing device. Through the cooperation of the guide block and the guide rod, the clamping plate moves smoothly during use, preventing the clamping plate from shaking.

[0016] This utility model provides a wind turbine cable anti-winding fixing device. By setting a tension spring, the guide block plays a role in preventing displacement during use. The guide block can be tightened, thereby increasing the clamping force between the clamping plate and the clamping seat, and preventing the cable from loosening and slipping.
