Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for cable laying, in particular to a cable water stop ring. Background Art

[0002] When carrying out cable laying construction, it is often adopted to pass the cable through the reserved cable perforation or the pre-buried cable protection sleeve to protect the cable, ensuring that the cable will not be damaged in the later stage.

[0003] However, at present, especially in the basement of buildings, a large number of rigid waterproof sleeves need to be pre-buried for the later entry of power cables. After the cable laying is completed, using the current common sealing measures, once the sealing is not in place, leakage often occurs at the sleeve. Moreover, the cable is a flexible material and is easily affected by temperature, causing thermal expansion and contraction, thus forming a small gap between the sealing material and the cable, resulting in repeated leakage, which poses a great potential safety hazard to the safe operation of the power distribution room power facilities and equipment. Therefore, a cable water stop ring is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model proposes a cable water stop ring. By tightly connecting the outer sleeve water stop belt with the sleeve and the inner cable water stop belt with the cable, a strict waterproof system is formed to reduce the risk of sleeve leakage.

[0005] The technical solution for realizing the purpose of the utility model is: a cable water stop ring, including a water stop sleeve sleeved on the pipe orifice of the pre-buried sleeve. The inner wall of the water stop sleeve is provided with an inner cable water stop belt, and the outer surface of the water stop sleeve is provided with an outer sleeve water stop belt. The cross-sections of the inner cable water stop belt and the outer sleeve water stop belt are both wavy, and a through hole for passing the cable is reserved in the center of the inner cable water stop belt.

[0006] In some embodiments, the inner cable water stop belt winds around the inner side of the water stop sleeve for one week and is seamlessly connected end to end, and the outer sleeve water stop belt winds around the outer surface of the water stop sleeve for one week and is seamlessly connected end to end.

[0007] In some embodiments, the inner diameter of the through hole is slightly smaller than the diameter of the cable.

[0008] Compared with the prior art, the utility model has the following remarkable advantages:

[0009] In the utility model, through the water stop sleeve sleeved on the pre-buried sleeve, the outer sleeve water stop belt is tightly connected with the sleeve, and the inner cable water stop belt is tightly connected with the cable, forming a strict waterproof system to reduce the risk of sleeve leakage. At the same time, the water stop sleeve made of rubber material has a certain error tolerance, and the sealing performance is not affected by temperature during use, and the sealing performance is more durable and stable. Moreover, the rubber material can be processed by die casting in production, which is conducive to standard batch production.

[0010] It solves the problem that when sealing a cable at present, due to the flexible material property of the cable, it is easily affected by temperature and causes thermal expansion and contraction, thus forming tiny gaps between the sealing material and the cable, resulting in repeated leakage.

[0016] 1. Water stop sleeve; 2. Inner cable water stop belt; 3. Outer sleeve water stop belt; 4. Through hole. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following details the present utility model. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] The present utility model provides a cable water stop ring through improvement. The technical solution of the present utility model is as follows:

[0019] As Figure 1 shown, a cable water stop ring includes a water stop sleeve 1 sleeved on the pipe orifice of a pre-embedded sleeve. The size of the entire water stop sleeve 1 can be customized according to the size of the pre-embedded sleeve, and the two can be better closely attached to ensure the sealing performance. An inner cable water stop belt 2 is arranged on the inner wall of the water stop sleeve 1, and an outer sleeve water stop belt 3 is arranged on the outer surface of the water stop sleeve 1. Both the inner cable water stop belt 2 and the outer sleeve water stop belt 3 are made of rubber and can be integrally formed with the water stop sleeve 1 by a mold. The cross-sections of both the inner cable water stop belt 2 and the outer sleeve water stop belt 3 are wavy. A through hole 4 for passing the cable is reserved in the center of the inner cable water stop belt 2. The inner diameter of the through hole 4 is determined by the size of the inner cable water stop belt 2 and can still be customized according to the cable diameter.

[0020] As Figure 2As shown, in one embodiment, the inner cable waterstop 2 winds around the inner side of the waterstop sleeve 1 for one week and is seamlessly connected end to end. The outer sleeve waterstop 3 winds around the outer surface of the waterstop sleeve 1 for one week and is seamlessly connected end to end. The outer sleeve waterstop 3 is tightly connected to the sleeve, and the inner cable waterstop 2 is tightly connected to the cable, forming a tight waterproof system to reduce the risk of sleeve leakage.

[0021] As Figure 3 shown, in one embodiment, the inner diameter of the through hole 4 is slightly smaller than the diameter of the cable. When the inner diameter of the through hole 4 is smaller than the diameter of the cable, the inner cable waterstop ring made of rubber will be deformed and extruded, further strengthening the connection tightness between the two and achieving a better sealing effect.

[0022] The specific working method is as follows: When the cable waterstop ring is used, first polish and remove rust from the inner wall and the outer side of the embedded sleeve, then apply anti-rust paint, then put the whole waterstop sleeve 1 on the pipe orifice of the embedded sleeve, and fix the waterstop sleeve 1 to the embedded sleeve with waterproof glue, etc. Then lay the cable and pass the cable through the through hole 4, and keep the inner cable waterstop 2 in close contact with the surface of the cable. Then seal the remaining parts by conventional means.

[0023] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed by the above technical means, but also include the technical solutions composed of equivalent replacements of the above technical features. The matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
