Velcro combination sealing device for all-round sealing of cabinet panel cable holes

Abstract

The invention discloses a nylon fastener tape combined sealing device for comprehensively plugging a cabinet screen cable hole, and belongs to the technical field of substation equipment plugging. Thenylon fastener tape combined sealing device comprises a first fixing mechanism, a second fixing mechanism, and a sealing mechanism connected with the first fixing mechanism and the second fixing mechanism. The first fixing mechanism comprises a nylon fastener tape A wrapping the wall of a hole and a positioning module used for fixing the nylon fastener tape A. The second fixing mechanism comprises a nylon fastener tape B wrapping the outer surface of a cable and a safety buckle ring arranged on the nylon fastener tape B. The sealing mechanism comprises a nylon fastener tape C adhered to the nylon fastener tape A and the nylon fastener tape B. The nylon fastener tape combined sealing device has the advantages of simple and convenient installation, firm and tight plugging, low cost, convenience of use, convenience of construction, overhaul and maintenance, and repeated use for many times, can directly and effectively meet the requirements of water resistance, fire resistance, smoke resistance and small animal resistance, and improves the safety and reliability of the cable operation environment.

AI Technical Summary

Problems solved by technology

[0002] At present, the plugging of cables and wire holes in boxes, cabinets, screens, etc., mostly adopts technical measures such as fireproof mud, cement, WQBZ inflatable pipe sealing bags, etc., which has many construction procedures, high input costs, and general plugging effect. , complex disassembly and maintenance, poor functions of fire prevention, smoke prevention, dust prevention, and small animal prevention, especially when encountering maintenance and new installation, it needs to be sealed again, which is time-consuming and laborious, wastes resources, and the sealing quality is difficult ensure

[0003] Among them: 1. Disadvantages of using fire-proof mud technology for plugging: (1) Fire-proof mud is most susceptible to environmental temperature changes to affect the quality and effect of plugging: when the ambient temperature is too high, the fire-proof mud will soften and overflow , causing the holes to be not tightly sealed; when the ambient temperature is too low, the fireproof mud will harden and fall off to form holes; resulting in poor effects of smoke prevention, fire prevention, dust prevention, and small animal prevention; (2), fireproof mud seals the holes The size requirements have great limitations: it is effective to seal holes in small cabinet screens, but it cannot effectively seal larger holes in cabinet screens. Refractory linings and other effective safety measures must be used. After fixing, the holes of cables and wires will be narrowed before they can be blocked with fireproof mud

[0004] 2. The disadvantages of using WQBZ inflatable pipe sealing bag technology for sealing: (1), it cannot effectively solve the problem of tight sealing between multiple cables or wire gaps; (2), the construction is complicated, when encountering cables , wire repair, maintenance and replacement, it needs to be re-made and blocked, time-consuming and laborious, the construction process is cumbersome, and the disassembly, maintenance and maintenance are complicated

(3) The use of WQBZ inflatable pipe sealing bag technology is not effective for boxes, cabinets, screens and other holes, because the walls of boxes, cabinets, screens and other holes are made of stainless steel or PVC materials with a thickness of 2mm-5mm

[0005] 3. The disadvantages of using the technology of cement inorganic mixed fireproof materials for sealing: it is only suitable for effective sealing of firewalls with large holes, between floors, and holes through walls, etc., but for boxes, cabinets, screens, etc. The plugging effect of cable and wire holes is very poor. Reasons: (1) Most of the holes for cables and wires in boxes, cabinets, screens, etc. are made of stainless steel and insulating and environmentally friendly materials. The walls of the holes are relatively thin, generally 2mm- 5mm, the use of cement inorganic mixed fireproof materials can not effectively fix and seal the holes; (2), prone to problems such as moisture return and water vapor; (3), the construction is complicated, when encountering cables and wires for emergency repair, maintenance and replacement, it is necessary to It is time-consuming and labor-intensive to re-make and seal, waste resources, the construction process is cumbersome, and the disassembly, maintenance and maintenance are complicated

[0008] Both of the above two sealing devices have disadvantages such as weak sealing, complex construction, cable replacement, inconvenient maintenance, time-consuming and laborious, etc., and are suitable for firewalls with large holes, holes through walls, etc., but not suitable for cables in boxes, cabinets, etc. hole
