Description

Technical Field

[0001] This utility model relates to the field of cable sealing technology, and in particular to a cable sealing structure for power cabinets. Background Technology

[0002] Power distribution cabinets are an important component of power systems, primarily responsible for the distribution, control, protection, and monitoring of electrical energy. Power distribution cabinets can be categorized into various types, including incoming line cabinets, outgoing line cabinets, metering cabinets, PT cabinets, tie cabinets, and isolation cabinets. Power distribution cabinets need to connect to external cables. Through internal devices, these external cables are transformed or their power is tested before being connected to other equipment. However, the openings at power distribution cabinet interfaces are often larger than the cable diameter, necessitating sealing of these openings.

[0003] In existing technologies, fireproof putty or foam material is usually used to seal the openings of power cabinets for cable blocking. When using these materials for sealing, a frame needs to be set up to hold the cables inside the frame. The inside of the frame is then filled with fireproof putty or foam material. This process is cumbersome, and the fireproof putty is prone to cracking, requiring timely replacement and inspection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable sealing structure for power cabinets, which has the advantages of strong sealing performance and high adaptability, thus solving the problems mentioned in the background art.

[0006] With the above-described structure, this device can be used to seal cables. Since there are multiple cables entering the power cabinet, this device can seal multiple cables at the same time without gaps between them, achieving the effect of multiple sealing without gaps.

[0007] Preferably, the block is a cuboid in shape, with large slots symmetrically opened between the middle blocks, a small slot opened between the middle block and the left block on one side, and a small slot opened between the middle block and the right block on the other side.

[0008] With the above structural design, different sizes of slots can be used to accommodate silicone rings of different sizes. The size of the slot determines the upper limit of the cable diameter.

[0009] Preferably, the silicone ring includes a silicone ring A and a silicone ring B, wherein silicone ring A is fixedly installed between the small grooves and silicone ring B is fixedly installed between the large grooves.

[0010] With the above structural setup, the difference between rubber ring A and rubber ring B is the number of rubber pad layers, which represents the upper limit of the maximum diameter that can be adapted.

[0011] Preferably, the rubber ring A and rubber ring B are composed of rubber pads, and the rubber ring A and rubber ring B are composed of a coaxial array of rubber pads with gradually increasing diameters. The connection between the rubber pads can be disengaged. The rubber ring A is divided into two parts along the central axis, one part is located inside the middle block, and the other part is located inside the left or right block. The rubber ring B is divided into two parts along the central axis, and each part is located inside one of the two middle blocks.

[0012] Preferably, the block is cylindrical, the groove is arc-shaped, and the retaining strip is deformable.

[0013] Through the above structural design, this device can be adapted to power cabinets of different specifications. In actual use, the overall thickness of the block and the number of array layers of the silicone ring can be changed according to the user's choice, achieving a perfect fit.

[0014] This utility model has the following advantages:

[0015] 1. This cable sealing structure for power cabinets achieves cable sealing by setting up blocking blocks, silicone rings, and other structures. The blocking blocks are separated, and the cables that need to pass through the side wall of the power cabinet are taken out and clamped between the left and middle blocks, or between the middle blocks, or between the right and middle blocks. Since there are many cables with different diameters inside the power cabinet, this device is equipped with multiple slots to seal between cables and between cables and the power cabinet. By tearing the rubber gasket, the diameter of the inner ring of the silicone ring is changed, so that the inner ring of the silicone ring can be adapted to cables of different diameters. Using this device to seal cables, multiple cables can be sealed at the same time without gaps between them, achieving the effect of multiple sealing without gaps.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-2 A cable sealing structure for an electrical cabinet includes a blocking block 1, which is a cuboid in shape. The blocking block 1 includes two middle blocks, a left block, and a right block. Slide grooves 2 are provided on the upper and lower sides of the blocking block 1. The cross-section of the slide grooves 2 is trapezoidal. A retaining strip 3 is slidably installed inside the slide grooves 2. The retaining strip 3 is made of silicone and has high friction. The shape of the retaining strip 3 is adapted to the slide groove 2. Ear blocks 4 are symmetrically fixed on the left and right sides of the blocking block 1. The surface of the ear blocks 4 has slots for fixing the device to one side or the bottom of the electrical cabinet with bolts. Silicone rings 5 ​​are evenly distributed inside the blocking block 1.

[0024] By using this device to seal cables, since there are more than one cable entering the power cabinet, when the cables are clustered together, there are still gaps between the cables when using conventional fireproof putty for sealing. Using this device to seal the cables can seal multiple cables at the same time, and there are no gaps between the cables, achieving the effect of multiple sealing and no gaps.

[0025] Please see Figures 1-2 Large slots are symmetrically opened between the middle blocks, small slots are opened between the middle block on one side and the left block on the other side, and small slots are opened between the middle block on the other side and the right block on the other side.

[0026] By setting different slot sizes, it is easy to adapt to silicone rings 5 ​​of different sizes. Different diameters of silicone rings 5 ​​represent cables of different diameters that can be adapted to. The size of the slot determines the upper limit of the cable diameter.

[0027] Please see Figures 1-2 The silicone ring 5 includes ring A and ring B. Ring A is fixedly installed between the small grooves, and ring B is fixedly installed between the large grooves.

[0028] The difference between rubber ring A and rubber ring B is the number of rubber pads, but the initial diameter of the adapter cable is the same, which means that the upper limit of the maximum diameter of the adapter is different.

[0029] Please see Figures 1-2 Rubber rings A and B are composed of rubber pads. Rubber rings A and B are coaxial arrays of rubber pads with gradually increasing diameters. The connection between the rubber pads can be disconnected. Rubber ring A is divided into two parts along the central axis. One part is located inside the middle block, and the other part is located inside the left or right block. Rubber ring B is divided into two parts along the central axis, located inside the two middle blocks respectively. Users can change the diameter between the rubber pads by tearing apart the connection between the rubber pads to adapt to cables of different diameters.

[0030] Please see Figures 1-2 The outer ring of the cable is circular, and the inner wall of the rubber pad is also circular. By adjusting the diameter of the inner wall between the rubber pads to match the outer ring of the cable, the rubber pads have high friction. Through the merging inside the plug 1, the cable is squeezed inside the plug 1, so that the position of the cable is fixed inside the plug 1.

[0031] Working principle: Separate the blocking blocks 1, take out the cables that need to pass through the side wall of the power cabinet, and clamp them between the left block and the middle block, or between the middle blocks, or between the right block and the middle block. Since there are many cables with different diameters inside the power cabinet, this device is equipped with multiple slots to seal between the cables and between the cables and the power cabinet. By tearing the rubber gasket, the diameter of the inner ring of the silicone ring 5 is changed so that the silicone ring 5 can be adapted to cables of different diameters and can seal multiple cables at once. After the blocking blocks 1 are clamped together, insert the clip 3 into the slide groove 2 and place the blocking block 1 at the cable opening position of the power cabinet. Use bolts to fix the blocking block 1 at the cable opening position through the lug 4 to achieve a complete seal. Example 2

[0032] Please see Figures 3-4 The block 1 is cylindrical in shape. The upper and lower sides of the block 1 are provided with grooves 2. The grooves 2 are arc-shaped and have a trapezoidal cross-section. A retaining strip 3 is slidably installed inside the grooves 2. The retaining strip 3 is made of rubber and can be deformed.

[0033] By setting up this device, it can be adapted to power cabinets of different specifications. In actual use, the overall thickness of the plug 1 and the number of array layers of the silicone ring 5 can be changed according to the user's choice. The ultimate goal is to make it easy for users to achieve a perfect fit in the cable sealing effect of the power cabinet.
