Full-sealed water, fire and explosion prevention cable joint safety box

Abstract

The invention discloses a full-sealed water, fire and explosion prevention cable joint safety box, comprising a shell made of a weak magnetic iron plate synthesis material. The shell is a cylinder molded from two semi cylindrical shells integrally once without welding, the two semi cylindrical shells of the shell are connected through a stock set screw at the explosion-proof inner hexagonal concave end, the diameters of both ends of the shell are reduced to form contraction openings, a section of cylinder with a small size is formed at each contraction opening, a waterproof sealing accessory made of a high-quality silicone rubber material is installed in each contraction opening, a fireproof flame-retardant insulating layer is adhered to the inner wall of the shell, and an anticorrosion and anti-ultraviolet powder is sprayed on the outer surface of the shell. The invention has the advantages that the shell is molded integrally without welding, is integrally treated by hot galvanizing and degaussing, is integrally sprayed with the anticorrosion and anti-ultraviolet material, and has the advantages of strong explosion-proof force, strong corrosion resistance and long aging resistance time. The traditional shell has common tensility and poorer explosion-proof force and is smelted to be in a carbonization state or seriously deforms for burning for a long time, and the fireproof flame-retardant insulating layer can fulfill the functions of fire prevention, flame retardancy and heat insulation.

Description

technical field [0001] The invention relates to a fully sealed waterproof, fireproof and explosion-proof safety box for cable joints. Background technique [0002] It is well known that the main material of the explosion-proof product shell is iron plate or steel plate, and the product body must be sealed; the so-called explosion-proof means that the explosion-proof effect can only be achieved when it is fully sealed. Because if the cable is not fully sealed when sparks are generated, there will be oxygen and air, so a fire will occur, and then an explosion will occur. Therefore, if the explosion-proof product is not completely sealed, it is absolutely impossible to achieve the explosion-proof effect. [0003] And we choose the cable explosion-proof box to achieve the expected effect. The reasons can be summarized into five situations: ①The quality of the cable accessories; The sealing cap seals it, and the cable has been damp); ③The installation process of cable accessori...

AI Technical Summary

Problems solved by technology

[0004] Most of our cables run in cable trenches or cable wells, so many accidents are affected by the operating environment, at least accounting for more than half of the factors, because they are often soaked in water, damp, air, etc., and then the cable head occurs Breakdown, spontaneous combustion, and more seriously, other cables will be damaged or even burned after the explosion
