Description

Technical Field

[0001] The utility model relates to the field of fireproof and explosion-proof protection boxes, in particular to a fireproof and explosion-proof box made of corrosion-resistant high-performance materials. Background Art

[0002] When a cable joint breaks down or explodes, a large amount of energy will be released, which will cause damage to other surrounding cable lines, facilities or personnel, and may even cause secondary accidents. Therefore, a fireproof and explosion-proof box is generally installed at the cable joint;

[0003] Chinese patent publication number CN202363862U discloses a protective box for high-voltage and ultra-high-voltage cross-linked cable intermediate joints. The protective device comprises a housing and a filler. The housing is cylindrical and divided into three sections: a left section, a middle section, and a right section. The cable intermediate joint is inserted into the housing, and the filler is located between the housing and the cable intermediate joint. Compared with existing technologies, this utility model has the advantages of a compact structure, light weight, and environmental friendliness.

[0004] The protective box of the above patent is provided with a filler between the shell and the cable connector, but the traditional filler will lose its elasticity after being squeezed and deformed by the cable for a long time, and will be unable to adapt to cables of different sizes, resulting in poor filling effect. Gaps will be generated between the cable and the shell, and rainwater will enter the protective box, causing the cable to short-circuit and cause the cable to be scrapped or burned. The increase in the cable scrap rate will undoubtedly increase the degree of environmental pollution. Utility Model Content

[0005] The purpose of the present utility model is to provide a fireproof and explosion-proof box made of corrosion-resistant high-performance materials, wherein air bags are provided on the inner walls of the first fixed tube and the second fixed tube provided at both ends of the protection box, and the first fixed tube and the second fixed tube are provided with gas pipes, and the upper ends of the gas pipes are provided with airtight valves. When the cable passes through the first fixed tube and the second fixed tube and is inserted into the protection box, the staff connects the hose with one end connected to the air pump to the gas pipe, opens the airtight valve, and the air enters the air bag along the gas pipe. The air bag starts to expand and abuts against the cable to fill the gap between the cable and the protection box, and due to the ductility of the air bag, it can adapt to cables of different sizes, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a fireproof and explosion-proof box made of corrosion-resistant, high-performance materials, comprising an upper box body, a hinge being provided at the rear end of the upper box body, a lower box body being provided on the end of the hinge away from the upper box body, and a first fixed tube being provided, the first fixed tube being provided at both ends of the upper box body, a first airbag being provided on the inner wall of the first fixed tube, a first gas pipe being provided at the upper end of the first fixed tube, a first airtight valve being provided in the middle section of the first gas pipe, second fixed tubes being provided at both ends of the lower box body, a second airbag being provided on the inner wall of the second fixed tube, and a second gas pipe being provided at the upper end of the second fixed tube.

[0007] Preferably, a second airtight valve is provided in the middle section of the second gas pipeline, and the second airtight valve is bolted to the second gas pipeline.

[0008] Preferably, the upper box body is provided with a first clamping plate on one end away from the hinge, and the first clamping plate is integrally provided with the upper box body.

[0009] Preferably, the first clamping plate is provided with a first clamping tooth, and the first clamping tooth and the first clamping plate are integrally provided.

[0010] Preferably, the lower box body is provided with a second clamping plate on one end away from the hinge, and the second clamping plate is integrally provided with the lower box body.

[0011] Preferably, the second clamping plate is provided with a second clamping tooth, and the second clamping tooth is engaged with the first clamping tooth.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the cable is passed through the first and second fixed tubes and inserted into the protective box, the staff connects the hose connected to the air pump at one end to the air supply pipe, opens the airtight valve, and air enters the air bag along the air supply pipe. The air bag starts to expand and abuts against the cable to fill the gap between the cable and the protective box. The air bag can adapt to cables of different sizes due to its ductility, effectively avoiding the problem that the existing protective box is provided with a filler between the shell and the cable connector. However, the traditional filler will lose its elasticity after being squeezed and deformed by the cable for a long time, and cannot adapt to cables of different sizes, resulting in poor filling effect. A gap is generated between the cable and the shell, and rainwater will enter the protective box, which will cause the cable to short-circuit and cause the cable to be scrapped and burned. The increase in the cable scrap rate will undoubtedly increase the degree of environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS
