Description

Technical Field

[0001] This utility model relates to the field of coal mine fire prevention and escape technology, and in particular to a coal mine underground fire prevention and escape device. Background Technology

[0002] Coal mines present a complex working environment prone to fires. The accumulation of flammable materials such as coal dust and gas, coupled with factors like aging equipment and short circuits, can all lead to fires. Therefore, appropriate fire prevention measures must be taken to reduce the risk of fires and ensure the timely and safe evacuation of miners in the event of a fire.

[0003] Currently, miners in coal mining operations generally lack necessary protective measures, which directly increases the risks they face during operations. In the event of a sudden fire during coal mining, miners often lack sufficient time and opportunity to react and escape, potentially leading to significant casualties and property damage.

[0004] Therefore, it is necessary to provide a fire prevention and escape device for underground coal mines that facilitates fire extinguishing, protection, and escape to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of a fire escape device for underground coal mines provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic. Figure 3 for Figure 2The diagram shows the structure of the fire extinguishing assembly. A coal mine underground fire escape device includes a base plate 1, a protective chamber 2 bolted to the top of the base plate 1, a spray pipe 3 flanged to one side of the top of the protective chamber 2, a fire door 4 hinged to the front end of the protective chamber 2, a storage box 5 bolted to one side of the top of the base plate 1, a feed inlet 6 flanged to the top of the storage box 5, a fire extinguishing assembly 7 installed on one side of the top of the base plate 1, the fire extinguishing assembly 7 being used for fire extinguishing, protection, and escape inside the mine, and a heat insulation layer 8 bolted to the top of the inner cavity of the protective chamber 2.

[0019] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the fire extinguishing assembly 7 includes a high-pressure pump 71. The bottom of the high-pressure pump 71 is bolted to the base plate 1. A feed pipe 72 is connected to a flange on one side of the high-pressure pump 71. One side of the feed pipe 72 is connected to a flange on the storage tank 5. A solenoid valve 73 is connected to a flange on one side of the high-pressure pump 71. A discharge pipe 74 is connected to a flange on one side of the solenoid valve 73. The top of the discharge pipe 74 is connected to a flange on the spray pipe 3.

[0020] When a fire occurs during mining and needs to be extinguished, the extinguishing powder is poured into the inner cavity of the storage tank 5 through the feed inlet 6 in advance. Then, the high-pressure pump 71 and the solenoid valve 73 are started. The suction force of the high-pressure pump 71 draws the powder from the storage tank 5 into the inner cavity of the feed pipe 72. Then, the powder is transported through the feed pipe 72 to the inner cavity of the discharge pipe 74. Then, the powder is transported through the discharge pipe 74 to the inner cavity of the spray pipe 3. Finally, the powder is sprayed out through the spray pipe 3 into the inner cavity of the protective chamber 2 to extinguish the fire inside. This can effectively extinguish fires, protect the mine, and facilitate escape.

[0021] refer to Figure 3 As shown, a positioning sleeve 9 is slidably fitted on the surface of the discharge pipe 74, and the rear end face of the positioning sleeve 9 is bolted to the protective chamber 2.

[0022] The connection between the positioning sleeve 9 and the protective chamber 2 effectively fixes the discharge pipe 74 in place.

[0023] refer to Figure 3 As shown, reinforcing blocks 10 are welded and fixed on both sides of the high-pressure pump 71, and the bottom of the reinforcing blocks 10 is bolted to the base plate 1.

[0024] The connection between the reinforcing block 10 and the base plate 1 effectively reinforces the high-pressure pump 71.

[0025] refer to Figure 2 and Figure 3 As shown, pulleys 11 are bolted to the four corners of the bottom of the base plate 1, and the bottom of the pulleys 11 slides in contact with the track inside the coal mine.

[0026] The sliding contact between pulley 11 and the track inside the coal mine facilitates the movement of the base plate 1.

[0027] The working principle of the underground fire escape device in a coal mine provided by this utility model is as follows:

[0028] When in use, if a fire occurs during mining and needs to be extinguished, the extinguishing powder is poured into the inner cavity of the storage tank 5 through the feed inlet 6 in advance. Then, the high-pressure pump 71 and the solenoid valve 73 are started. The suction force of the high-pressure pump 71 draws the powder from the storage tank 5 into the inner cavity of the feed pipe 72. Then, the powder is transported through the feed pipe 72 to the inner cavity of the discharge pipe 74. Then, the powder is transported through the discharge pipe 74 to the inner cavity of the spray pipe 3. Finally, the powder is sprayed out through the spray pipe 3 into the inner cavity of the protective chamber 2 to extinguish the fire inside. Then, the personnel inside the protective chamber 2 can escape through the fire door 4 in sequence.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
