It includes a support ring with a wind power cable limiting assembly. The wind power cable limiting assembly includes several arc-shaped vertical plates fixedly installed at the top and bottom of the support ring. Several heat dissipation fins are equidistantly arranged on the outer wall of each arc-shaped vertical plate. A C-shaped plate is located at the end of the inner wall of each arc-shaped vertical plate away from the support ring.

Description

Technical Field

[0001] This utility model provides a layered storage and protection structure for wind power cables, belonging to the field of wind power generation technology. Background Technology

[0002] As the installed capacity of wind turbine generators increases, the demand for cables used in wind turbine generators is also growing. Specialized cables for wind turbine generators typically include power cables, control cables, and communication cables (data cables). During use, depending on design requirements, wind turbine generator cables may have tens of meters of suspended sections (the vertically laid portion within the wind turbine generator tower), thus requiring cable entry point securing and clamping.

[0003] The wind power cable fixing, storage, and protection structure inside the tower can basically meet normal usage needs, but there are still corresponding defects:

[0004] When current flows through a cable, its own resistance generates heat. As the capacity of the unit increases and the number of cables increases, the cables tend to become bundled, which prevents the cables from dissipating heat in time. This can lead to overheating, causing the cable sheath to crack and turn white, accelerating cable aging, and affecting the safe operation of the fan.

[0005] Furthermore, since fixed storage and protection structures are typically limited in height and generally only fix a single point on the wind power cable, this results in a single fixing point and inadequate storage and protection when fixing the wind power cable. Therefore, this invention provides a layered storage and protection structure for wind power cables. Utility Model Content

[0006] The technical problems solved by this utility model are: the failure of cable bundles to dissipate heat in time leads to overheating, causing the cable sheath to crack and turn white, accelerating cable aging, and affecting the safe operation of wind turbines; and the single fixing point of wind power cables results in poor storage and protection when fixing wind power cables.

[0007] To solve the technical problem, the technical solution provided by this utility model is as follows: a layered storage and protection structure for wind power cables, including a support ring, on which a wind power cable limiting component is provided. The wind power cable limiting component includes several arc-shaped vertical plates fixedly installed at the top and bottom of the support ring. Several heat dissipation fins are equidistantly arranged on the outer wall of the arc-shaped vertical plates. A C-shaped plate is provided at the end of the inner wall of the arc-shaped vertical plates away from the support ring. A V-shaped clamping block is slidably connected between the inner walls of the C-shaped plates. A screw threadedly connected to the outer wall of the V-shaped clamping block is rotatably connected to the side wall of the C-shaped plate.

[0008] Furthermore, the outer wall of the support ring is symmetrically provided with support arms on both sides, and the end of the support arm is provided with a mounting seat.

[0009] Furthermore, several of the arc-shaped vertical plates at the same height are distributed equidistantly around the circumference, with the upper and lower arc-shaped vertical plates symmetrically arranged on both sides of the support ring.

[0010] Furthermore, the other end of the screw is provided with a handwheel located on the outside of the C-shaped plate, and the two inner sidewalls of the C-shaped plate are symmetrically provided with limiting grooves that match the sidewalls of the V-shaped clamping block.

[0011] Furthermore, the inner wall of the V-shaped clamping block is provided with a V-shaped anti-slip pad.

[0012] Furthermore, a reinforcing connecting plate is provided between the side walls of adjacent C-shaped plates at the same height that are close to each other.

[0013] The beneficial effects of this utility model are:

[0014] Symmetrical arc-shaped vertical plates at the top and bottom create layered storage spaces. Wind power cables are attached to the inner wall of the arc-shaped vertical plates, with the upper and lower ends of the cables clamped between V-shaped clamps and the inner wall of the arc-shaped vertical plates. This design achieves layered storage and protection of the wind power cables, ensuring good storage and protection when the cables are fixed. Combined with heat dissipation fins, this accelerates heat dissipation, meeting the heat dissipation requirements of high-power cables. This prevents overheating that could cause the cable sheath to crack and turn white, avoiding accelerated cable aging and ensuring the safe operation of the wind turbine. Attached Figure Description

[0024] As per the instruction manual Figure 1 , 3 As shown: The support ring 1 is equipped with a wind power cable limiting component 2. The wind power cable limiting component 2 includes several arc-shaped vertical plates 3 fixedly installed at the top and bottom of the support ring 1. The several arc-shaped vertical plates 3 at the same height are distributed equidistantly in a circle. The upper arc-shaped vertical plates 3 and the lower arc-shaped vertical plates 3 are symmetrically arranged on both sides of the support ring 1. Several heat dissipation fins 7 are equidistantly arranged on the outer wall of the arc-shaped vertical plates 3. Specifically, the arc-shaped vertical plates 3 are made of metal materials with fast heat dissipation, such as aluminum alloy. The arc-shaped vertical plates 3 symmetrically arranged at the top and bottom and distributed in a circle form an upper and lower layered storage space. The wind power cable is attached to the inner wall of the arc-shaped vertical plates 3 for layered storage and protection.

[0025] As per the instruction manual Figure 2 , 3As shown: A C-shaped plate 4 is provided at the end of the inner wall of the arc-shaped vertical plate 3 away from the support ring 1. A reinforcing connecting plate 12 is provided between the side walls of adjacent C-shaped plates 4 at the same height to strengthen the support. A V-shaped clamping block 5 is slidably connected between the inner walls of the C-shaped plates 4. A V-shaped anti-slip pad 11 is provided on the inner wall of the V-shaped clamping block 5 to prevent slipping, increase friction and prevent the cable from being pinched. The two inner walls of the C-shaped plate 4 are symmetrically provided with limiting grooves 10 that match the side walls of the V-shaped clamping block 5 to limit the V-shaped clamping block 5. A screw 6 is rotatably connected to the outer wall of the V-shaped clamping block 5 and threadedly connected to the side wall of the C-shaped plate 4. A handwheel is provided at the other end of the screw 6 and placed on the outside of the C-shaped plate 4. In use, by holding the handwheel, the screw 6 is rotated and moved, which in turn drives the V-shaped clamping block 5 to move.

[0026] As an optional embodiment, those skilled in the art can obtain the following based on their own knowledge and common sense: for the problem of dust and rust on the exposed screw, the dust can be cleaned regularly; for the screw, galvanizing or coating can be used to prevent rust and increase service life; when it is rusted to the point of being unusable, it can be replaced.

[0027] The principle of this utility model

[0028] In use, the support arm 8 and the mounting base 9 are symmetrically arranged on both sides of the support ring, which facilitates fixation inside the tower and adapts to the spatial layout of wind power equipment. The support ring 1 serves as the core carrier, and the top and bottom are symmetrically arranged with arc-shaped vertical plates 3 distributed in a circular pattern to form upper and lower layered storage space. The wind power cable is attached to the inner wall of the arc-shaped vertical plate 3. By holding the handwheel and rotating the pulley screw 6, it can be rotated and moved, which in turn can drive the V-shaped clamp 5 to move. The cable is clamped between the V-shaped clamp 5 and the inner wall of the arc-shaped vertical plate 3, which is used to achieve layered storage and protection of the wind power cable. When the wind power cable is fixed, the storage and protection are good. With the heat dissipation fins 7, the heat dissipation is accelerated to meet the heat dissipation requirements of high-power cables, so as to prevent overheating from causing the cable sheath to crack and turn white, and avoid accelerating cable aging, so as not to affect the safe operation of the wind turbine.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
