Description

Technical Field

[0001] The utility model relates to the technical field of fireproof trough boxes, in particular to a fireproof trough box with an active fire extinguishing function. Background Art

[0002] The fireproof trough box is a product used for fire prevention, which has the characteristics of good heat insulation, fire prevention, non-flammability, non-explosion, water resistance, oil resistance, chemical corrosion resistance, good weather resistance, non-toxicity, good mechanical strength, light weight, large bearing capacity, safety and reliability. The fireproof trough box is safe and reliable, easy to install, and can be processed by sawing, drilling, planing and other mechanical processing. It is suitable for fire-resistant separation during cable laying and is an ideal material for effectively preventing the flame from spreading when the cable catches fire. In the prior art, after the fireproof trough box is used, if the cable in the box catches fire, it can self-extinguish due to lack of oxygen due to the closed nature of its own structure, and the external fire will not affect the cable in the box due to the non-flammable nature of the trough box material. However, the fire inside the fireproof trough box needs to wait until the oxygen is burned out before it can be extinguished. The fire extinguishing method is relatively passive, and the fire extinguishing efficiency of the fireproof trough box is low. Even if some fireproof trough boxes adopt active fire extinguishing, which can speed up the fire extinguishing efficiency, the fire extinguishing components can work for a short time, leaving a short time for staff to deal with it.

[0022] The box cover 3 is placed on the upper surface of the box body 1. The left and right ends of the box cover 3 are provided with limit slide plates 4. The limit slide plates 4 are longitudinally slidably connected with the limit slide grooves 2. The position of the box cover 3 and the box body 1 is limited by the longitudinal sliding of the limit slide plates 4 and the limit slide grooves 2, so that the box cover 3 closes the upper end of the box body 1. The lower surface of the box cover 3 is provided with a hollow fireproof plate 6. The hollow fireproof plate 6 and the fireproof plate 5 made of titanium-steel composite material are used to provide fire protection for the cables. The lower surface of the hollow fireproof plate 6 is provided with fire extinguishing holes 7. Dry powder bags 8 are placed at the left and right ends of the hollow fireproof plate 6. 8 is a polyester non-woven fabric wrapped with sodium bicarbonate. The sodium bicarbonate inside the dry powder bag 8 is decomposed into carbon dioxide at high temperature, which increases the air pressure inside the hollow fireproof board 6. Under the action of the air pressure, the carbon dioxide flows into the box body 1 from the fire extinguishing hole 7, reduces the oxygen concentration inside the box body 1, and actively extinguishes the fire. The mounting holes on the lower surface of the hollow fireproof board 6 are all provided with heat conducting plates 9. The heat conducting plates 9 are L-shaped plates. The vertical plate surfaces of the heat conducting plates 9 are respectively provided with air holes 10. The dry powder bags 8 are respectively fitted with the vertical plates of the heat conducting plates 9. The heat conducting plates 9 are metal plates. The heat conducting plates 9 are used to quickly conduct heat to the dry powder bags 8. The hole 10 provides space for the circulation of carbon dioxide. The left and right ends of the hollow fireproof plate 6 are horizontally slidably connected with push plates 11. Tension springs 12 are provided between the push plates 11 and the vertical plates of the heat conducting plate 9. The dry powder bag 8 is located between the push plates 11 and the vertical plates of the heat conducting plate 9. During the fire extinguishing process, under the elastic force of the tension spring 12, the push plates 11 are used to apply force to the dry powder bag 8, so that the dry powder bag 8 is always in contact with the vertical plates of the heat conducting plate 9, so that the fire extinguishing components can work for a long time. The upper end of the inner part of the fire extinguishing hole 7 is provided with a rubber pad 13, and the middle part of the rubber pad 13 is provided with a slot to the upper end of the fire extinguishing hole 7. The upper end of the fire extinguishing hole 7 is opened by utilizing the deformation of the rubber pad 13; the inner lower end of the fire extinguishing hole 7 is provided with a wax sealing layer 14 to seal the lower end of the fire extinguishing hole 7; the high temperature generated by the combustion will melt the wax sealing layer 14 to open the lower end of the fire extinguishing hole 7; the bottom wall of the limiting slide groove 2 is provided with a rubber protrusion 15; the rubber protrusion 15 is deformed to increase the friction between the limiting slide plate 4 and the limiting slide groove 2; the left and right sides of the box body 1 are provided with heat dissipation holes 16; the surface of the fireproof board 5 is provided with a yield hole which is installed in cooperation with the heat dissipation hole 16 to dissipate the heat inside the box body 1 to the outside.

[0023] The working principle of a fireproof slot box with active fire extinguishing function provided by the utility model is as follows: when in use, the cable is located inside the box body 1, and the position of the box cover 3 and the box body 1 is limited by the longitudinal sliding of the limiting slide plate 4 and the limiting slide groove 2, so that the box cover 3 closes the upper end of the box body 1, and the hollow fireproof plate 6 and the fireproof plate 5 made of titanium steel composite material are used to provide fire protection for the cable. When the cable catches fire, the high temperature generated by the combustion will melt the wax sealing layer 14, so that the lower end of the fire extinguishing hole 7 is opened, and at the same time, the high temperature is quickly conducted to the heat conducting plate 9 made of metal material. Inside the dry powder bag 8, the sodium bicarbonate inside the dry powder bag 8 decomposes into carbon dioxide at high temperature, which increases the air pressure inside the hollow fireproof plate 6. Under the action of the air pressure, the rubber pad 13 is deformed, and the upper end of the fire extinguishing hole 7 is opened. Carbon dioxide flows out through the fire extinguishing hole 7 into the box body 1, reducing the oxygen concentration inside the box body 1, and actively extinguishing the fire. During the fire extinguishing process, under the elastic force of the tension spring 12, the push plate 11 is used to apply a force to the dry powder bag 8, so that the dry powder bag 8 is always in contact with the vertical plate of the heat conducting plate 9, so that the fire extinguishing component can work for a long time.
