Embodiment 1

[0021] Such as figure 1 , figure 2 As shown, the fire prevention plugging depth control device includes a supporting piece 1, the middle part of the supporting piece 1 is provided with a through hole 11 for the cable to pass through, and the supporting piece 1 is provided with an opening 12 communicating with the through hole 11, supporting The sheet 1 is provided with a holding hoop 2 for holding the cable tightly, and the holding hoop 2 is provided with a space 20 filled with fireproof blocking material, and the supporting sheet 1 is provided with a fixing device for clamping the supporting sheet 1 on the protective tube. Sheet 3; supporting sheet 1, holding hoop 2 and fixing sheet 3 are all made of the following components: polycarbonate 85.2%, glass fiber 12.3%, toughening agent 0.55%, titanium dioxide 0.46%, high-temperature color powder 0.32%, anti-ultraviolet additive 0.37%, anti-sunlight agent 0.3%, flame retardant 0.5%.

[0022] The hoop 2 includes multiple hoop pi...

Embodiment 2

[0024] As in the first embodiment of the fire prevention blockage depth control device, this embodiment has the following differences: the supporting sheet 1, the holding hoop 2 and the fixing sheet 3 are all prepared from the following components: polycarbonate 87.6% , glass fiber 11.05%, toughening agent 0.34%, titanium dioxide 0.23%, high temperature color powder 0.15%, anti-ultraviolet additive 0.22%, anti-sunshine agent 0.17%, flame retardant 0.24%.

Embodiment 3

[0026] As described in Embodiment 1, the fire prevention blockage depth control device has the following differences: the supporting piece 1, the holding hoop 2 and the fixing piece 3 are all prepared from the following components: polycarbonate 90.3% , Glass fiber 9.7%.

[0027] When in use, the main material is formed by mixing polycarbonate and glass fiber, and then according to different installation environments and use environments, tougheners, titanium dioxide, high-temperature color powder, anti-ultraviolet additives, anti-sunshine agents, Flame retardant, according to the different types of cables, adjust the opening 12 so that the cables are installed and fixed in the through holes 11, and the cables are tightly held on the supporting piece 1 through the clamping hoop 2, and then the supporting piece 1 is clamped through the fixing piece 3 Connect it to the protective pipe, and finally fill the space 20 provided in the holding hoop 2 with the fireproof blocking mater...

Abstract

The invention relates to a fireproof sealing depth control device, which comprises a bearing plate, wherein a through hole for a cable to penetrate through is formed in the middle of the bearing plate; an opening communicating with the through hole is formed in the bearing plate; a hoop for tightly holding a cable is arranged on the bearing plate; a space for being filled with a fireproof blocking material is arranged in the hoop; a fixing plate for clamping the bearing plate on a protective pipe is arranged on the bearing plate. The fireproof sealing depth control device provided by the invention has the advantages that the cable is arranged in the through hole of the bearing plate, and is tightly held by the hoop, and the space of the hoop is filled with the fireproof blocking material, so that the friction forces between the fireproof blocking material and the cable as well as the fireproof blocking material and a pipe wall can be effectively increased, the control device is enabled to have the weight for bearing the fireproof blocking material, the repaired fireproof blocking material can be effectively prevented from sliding downwards along an inner wall of the protective pipe, a use effect of the fireproof blocking material of the cable is fully played, the safety operation of the cable is effectively protected, the installation time and the maintenance time are saved, and the cost is saved.

Description

technical field [0001] The invention relates to a fire prevention plugging depth control device. Background technique [0002] At present, with the planning requirements of urban landscape, greening, building layout, etc., the number of reconstruction projects for overhead lines in distribution network projects has increased, and the engineering tasks of civil engineering are arduous. The amount of cable laying in cable wells has increased sharply. The main task is to improve the internal quality and external appearance of the fireproof blockage. The fireproof sealing of the cable protection nozzle of the cable well is unqualified. Not only can it not prevent the cable fire from spreading, but it will also become a place for small animals to damage the cable. Generally, the fireproof sealing of the cable protection nozzle of the cable well is a pull-through type cable that runs through as a small solid cylinder. In the large hollow cylinder, that is, the cable protection tu...
