Description

Technical Field

[0001] The utility model relates to the technical field of fire doors, in particular to a tunnel fire door for coal mines. Background Art

[0002] A coal mine is a reasonable space excavated by humans when digging geological layers rich in coal. It usually includes tunnels, shafts, and mining faces, etc. Coal is formed by lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or in mud. It is formed by natural coalification over a long geological period. When an emergency such as a fire occurs in a coal mine, people pass through the safe area behind the fire door to reduce casualties.

[0003] Although existing fire doors can play a role in fire prevention, as the fire spreads and the temperature increases, the fire resistance time of fire doors is limited;

[0004] The existing patent (publication number: CN214247414U) is a coal mine underground partition fire door. By setting a booster pump, when the booster pump is working, the booster pump can draw water inside the fixed frame into the inside of the booster pump through the inner tube, and then send the water to the inside of the water inlet block through the hose. By setting a nozzle, when the water pressure inside the water inlet block is too high, the water inside the water inlet block is sprayed out through the nozzle. When the water flow is sprayed out of the nozzle, the fire inside the mine can be isolated. At the same time, the water sprayed by the nozzle can also cool the door frame of the fire door, thereby improving the fire resistance of the device and facilitating the isolation of the spread of fire.

[0005] In response to the above problems, the existing patent provides a solution, but when a fire occurs, the user still needs to manually start the booster pump to reduce the fire. When a fire occurs, the staff needs to evacuate the tunnel as soon as possible. If they stay in the tunnel and start the booster pump, the staff's escape time will be delayed, which is less safe.

[0006] For this reason, a coal mine tunnel fire door is proposed. Summary of the Invention

[0037] Specifically, such as Figure 1 As shown, a warning light 5 is bolted to the outer wall of the door frame 1 . The warning light 5 is electrically connected to the temperature sensor 309 . There are four warning lights 5 and they are evenly distributed.

[0038] Specifically, such as Figure 7As shown, the internal thread of the flow guide tube 308 is connected to the round tube 6, and the filter screen 7 is arranged inside the round tube 6.

When a fire occurs, the temperature sensor 309 will sense the temperature of the flame. When the temperature reaches a predetermined value, the booster pump 305 will start, and then the external water will pass through the guide pipe 308 and then be filtered by the filter 7, and then enter the interior of the cavity 301, thereby preventing the nozzle 3 from being burned. 04 is blocked, and then the booster pump 305 draws water into the drain pipe 307 and the water collecting frame 302 through the water inlet pipe 306, and then the water is discharged through the drain trough 303 and the nozzle 304, thereby playing the role of extinguishing the fire and slowing down the fire, and then the water sprayed from the nozzle 304 may fall on the door frame 1, and the door frame 1 can also be cooled at this time. When a fire occurs, the temperature sensor 309 can also start the warning light 5, and the warning light 5 sounds an alarm, thereby informing the workers and allowing the workers to escape in advance. When the filter 7 needs to be replaced, the round tube 6 can be rotated out through the raised plate 9 and then replaced.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
