Description

Technical Field

[0001] The utility model relates to the technical field of cable scratch prevention, in particular to a cable scratch prevention device for entering a cabinet and a DC switch cabinet. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] At present, rubber rings are generally used for primary cables entering DC switch cabinets to prevent the cables from being scratched. This method first requires opening a hole in the cabinet bottom plate according to the outer diameter of the cable, and the diameter of the hole is slightly larger than the outer diameter of the cable; then select a suitable rubber ring, and the diameter of the rubber ring also needs to be slightly larger than the outer diameter of the cable.

[0004] The bottom plate opening and the rubber ring can only be slightly larger than the outer diameter of the cable, not too much, otherwise the fireproof mud cannot be covered on site, which will cause difficulties when threading the cable on site. There is a risk of the rubber ring falling off when the cable enters the cabinet, and the cable will swing due to the electric force at the moment of power-on, causing scratches on the cable. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the embodiments of the utility model is to provide an anti-scratch device for incoming cables and a DC switch cabinet, which can improve the convenience of primary cable installation while meeting the anti-scratch effect for incoming cables.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] A device for preventing cables from being scratched when entering a cabinet, comprising a DC switch cabinet bottom plate, a first anti-scratch plate and a second anti-scratch plate;

[0008] The DC switch cabinet bottom plate is provided with a total cable through hole, the length of the total cable through hole is greater than the total length of all incoming cables, and the width of the total cable through hole is greater than the outer diameter of the incoming cables;

[0009] A plurality of upper cable clamping holes are provided on one side of the first anti-scratch plate along the length direction, and a plurality of lower cable clamping holes are provided on the other side of the second anti-scratch plate along the length direction, and the number of the upper cable clamping holes and the lower cable clamping holes is equal to the number of cables entering the cabinet;

[0010] The first anti-scratch plate and the second anti-scratch plate are arranged on the bottom plate of the DC switch cabinet, and the first anti-scratch plate and the second anti-scratch plate cover the main cable through hole; the upper cable clamp hole is located in front of the incoming cable, and the lower cable clamp hole is located behind the incoming cable, and the upper cable clamp hole and the lower cable clamp hole constitute a storage space for the incoming cable.

[0011] By adopting the above technical solution, a large-sized cable hole is opened on the bottom plate of the DC switch cabinet to facilitate the entry and installation of the cable into the cabinet. After the cable is fixed, the first anti-scratch plate and the second anti-scratch plate are buckled from the front and back of the cable, and the first anti-scratch plate and the second anti-scratch plate are fixed on the bottom plate. The gap between the first anti-scratch plate and the second anti-scratch plate is very small, which is convenient for covering the position of the cable with fireproof mud after the cabinet is installed. Since the gap between the first anti-scratch plate and the second anti-scratch plate is very small, the swing caused by the instantaneous power-on of the cable can be restrained.

[0012] Furthermore, it also includes a first anti-scratch strip and a second anti-scratch strip;

[0014] By adopting the above technical solution, the gap between the first anti-scratch plate, the second anti-scratch plate and the cable is made smaller, thereby preventing the fireproof mud from falling off; and preventing the first anti-scratch plate and the second anti-scratch plate from scratching the cable when the cable swings.

[0015] Preferably, the first anti-scratch strip and the second anti-scratch strip are made of sponge, the shape and size of the first anti-scratch strip match the shape and size of the upper cable clamp hole, and the shape and size of the second anti-scratch strip match the shape and size of the lower cable clamp hole.

[0016] By adopting the above technical solution, the sponge is made of flexible material and can provide better protection for the cables entering the cabinet.

[0017] Furthermore, it also includes a fireproof layer;

[0018] The fireproof layer is arranged on the first anti-scratch plate and the second anti-scratch plate, and the fireproof layer covers the upper cable clamping hole and the lower cable clamping hole.

[0019] By adopting the above technical solution, it is possible to prevent a fire in the cable from spreading from the hole to the adjacent room, reduce fire losses, and prevent external moisture from entering the switch cabinet.

[0020] Preferably, the fireproof layer is made of fireproof mud.

[0021] Furthermore, the upper cable clamp hole and the lower cable clamp hole are both U-shaped clamp holes, and the opening end of the upper cable clamp hole is connected to the opening end of the lower cable clamp hole to form an accommodating space for the incoming cables;

[0022] The distribution positions of the upper cable clamping holes and the lower cable clamping holes are consistent with the distribution positions of the cables entering the cabinet.

[0023] By adopting the above technical solution, after the cable is fixed, the anti-scratch plate can be buckled into the cable from the front and back, thereby achieving convenient cable installation.

[0024] Furthermore, it also includes an anti-scratch rubber strip, which is arranged on the inner side of the circumference of the main cable through hole.

[0025] By adopting the above technical solution, the cable can be prevented from being scratched by the bottom plate during the cable threading process.

[0026] Furthermore, the first anti-scratch plate and the second anti-scratch plate are both provided with mounting through holes, and the first anti-scratch plate and the second anti-scratch plate are fixed to the bottom plate of the DC switch cabinet by means of rivet screws and the mounting through holes.

[0027] By adopting the above technical solution, the anti-scratch plate can be fixed to the base plate by using self-clinching screws, which is easy to operate.

[0028] Furthermore, the first anti-scratch plate and the second anti-scratch plate are made of SMC material.

[0029] By adopting the above technical solution, the first anti-scratch plate and the second anti-scratch plate are made of SMC material, which will not cause scratches on the cable.

[0030] The embodiment of the utility model further provides a DC switch cabinet, comprising the above-mentioned cabinet-entry cable anti-scratch device.

[0031] The technical solution provided by the utility model has at least the following technical effects or advantages:

[0032] 1. The technical solution provided by the utility model designs a device for preventing cables from being scratched when entering the cabinet, which is convenient for cables to enter the cabinet and be installed. After the cables are fixed, the first anti-scratch plate and the second anti-scratch plate are fixed to the bottom plate of the DC switch cabinet. The gap between the anti-scratch plate and the cable is very small, which is convenient for covering the cable position with fireproof mud (fireproof layer) after the cabinet is installed. The swing caused by the instantaneous power-on of the cable can be restrained to prevent the cable from being scratched.
