Cable hole blocking apparatus and blocking process

Abstract

The invention provides a cable hole blocking apparatus. The cable hole blocking apparatus comprises fireproof partition plates and a fireproof supporting plate; the section of the fireproof supportingplate is semicircular annular; the fireproof supporting plate is used for supporting a cable, so that the cable does not apply force on the subsequently filled fireproof blocking material, falling off of the fireproof blocking material caused by stress can be avoided, and high sealing performance of the subsequently filled fireproof blocking material is ensured; the number of the fireproof partition plates is two, and the section of each fireproof partition plate is sector-ring-shaped; the central angle of the fireproof partition plates is greater than 90 degrees; the two fireproof partitionplates are rotationally connected with the two ends of the fireproof supporting plate, so that superposition between the center of circle of the section of the fireproof supporting plate and the center of circle of the section of the two fireproof partition plates can be prevented; the fireproof supporting plate and the two fireproof partition plates are matched to form a cavity for allowing the cable to pass through; the fireproof partition plates are rotated to form an opening between the two fireproof partition plates, so that the cable can be put in and taken out conveniently; the cable can be fixed by closing the two fireproof partition plates; and therefore, the blocking apparatus can be detached and assembled very conveniently, without damaging the cable.

Description

technical field [0001] The invention relates to the technical field of cable hole plugging, in particular to a cable hole plugging device and a plugging process. Background technique [0002] The sealing of the traditional cable hole is usually to add a baffle to the opening of the cable hole first, and then seal it with a fireproof blockage. The function of the baffle prevents the fireproof blockage from falling into the hole. After a period of time, the baffle may break Displacement will cause the fireproof blockage to sink and collapse, which will reduce the sealability and fireproofness of the blockage, and the effect of fireproofing, waterproofing and sundry prevention is not good, and cannot meet the requirements of cable operation. In order to solve this problem, various sealing devices have appeared on the market, such as inflatable cable duct sealing devices, which can have good sealing performance, but cannot meet the fire protection requirements; such as cork seal...

[0002] The sealing of the traditional cable hole is usually to add a baffle to the opening of the cable hole first, and then seal it with a fireproof blockage. The function of the baffle prevents the fireproof blockage from falling into the hole. After a period of time, the baffle may break The displacement will cause the fireproof blockage to sink and collapse, which will reduce the sealability and fireproofness of the blockage, and the effect of fireproofing, waterproofing, and debris prevention is not good, and cannot meet the requirements of cable operation.

In order to solve this problem, various sealing devices have appeared on the market, such as inflatable cable duct sealing devices, which can have good sealing performance, but cannot meet the fire protection requirements; such as cork sealing devices, which can have good fire protection, Waterproof performance, but the operation of disassembly and assembly is complicated, and it will cause damage to the cable
