Embodiment 1

[0050] Such as Figure 1-Figure 8 As shown, a blocking device for coal mine fire prevention includes a blocking mechanism 1 for flame retardant and smoke prevention, an energy supply mechanism 3 for providing gas source to the blocking mechanism 1, and an external connection for assembling multiple groups of blocking mechanisms 1 Mechanism 2, an external connection mechanism 2 is installed on the outside of the blocking mechanism 1, an energy supply mechanism 3 is connected to the gas supply end of the blocking mechanism 1, and a connecting mechanism 4 is arranged between the blocking mechanism 1 and the energy supply mechanism 3;

[0051] The blocking mechanism 1 includes a fireproof layer 11, a top inflatable bag 12, a side airbag 13, and a central airbag 14. A flame-retardant blanket 16 is arranged inside the fireproof layer 11, and a top inflatable bag 12 is arranged on the top inside of the fire-retardant blanket 16. The top inflatable bag 12 The two ends are connected wi...

Embodiment 2

[0056] Such as Figure 9 , the difference between this embodiment and embodiment 1 is:

[0057] The connection mechanism 4 includes a first magnet 411 and a second magnet 412. The first magnet 411 is fixed on the inner surface of the fixed box 31, and the second magnet 412 is fixed on the outer surface of the connection box 32. When the fixed box 31 and the connection box 32 need to be connected, Align the first magnet 411 with the second magnet 412 to quickly install.

[0058] A method for using a plugging device for coal mine fire prevention, comprising the following steps:

[0059] a. According to the actual situation in the tunnel, select the appropriate interval to fix the device on both sides of the tunnel with straps 21. When a fire breaks out in the tunnel, the biggest source of danger comes from dense smoke. When a fire breaks out in the tunnel, use the fireproof layer 11 The external reflective paint can quickly find the device body;

[0060] b. Spread out the fir...

Abstract

The invention discloses a plugging device for coal mine fire prevention and a using method thereof. The plugging device comprises blocking mechanisms used for flame retardance and smoke prevention, an energy supply mechanism used for providing an air source for the blocking mechanisms and an outer connecting mechanism used for assembling the multiple sets of blocking mechanisms, wherein the outer connecting mechanism is installed outside the blocking mechanisms; and an air supply end of each blocking mechanism is connected with the energy supply mechanism, and a connecting mechanism is arranged between the blocking mechanisms and the energy supply mechanism. The plugging device is advantaged in that a top inflation bag and side air bags are inflated through a quick inflation structure, so a smoke barrier can be quickly formed, the plugging effect is improved, the matching effect of the device and a tunnel is improved and safety is improved in cooperation with inflation of the internal center air bag, and the device is stored and fixed in a rolling mode; and the device can be arranged in the tunnel in a multi-range mode, operation in the tunnel cannot be affected, portability and operability are improved, inflation is conducted in a manual and electric mode, external influences are avoided, multiple assemblies can be matched, and environmental adaptability is improved.

Description

technical field [0001] The invention relates to the field of fire prevention in coal mines, in particular to a plugging device for fire prevention in coal mines and an application method thereof. Background technique [0002] At present, the method of sealing the gas in the goaf is mainly adopted to seal the gas in the goaf. However, there are defects such as slow construction of closed walls, too many closed walls increase the consumption of manpower and material resources, the construction cost is high, the applicability is poor, or the way of fire doors is adopted, and this arrangement is time-consuming and laborious, and often will affect the work. Contents of the invention [0003] The object of the present invention is to provide a coal mine fire prevention plugging device and its application method in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] A blocking device ...
