Problems solved by technology

In order to cut off the air in the roadway from entering the goaf, a roadway sealing device is needed to avoid a large amount of mining coal combustion and gas gas entering the combustion area and causing an explosion, causing safety accidents and causing coal loss
However, due to the instability of the spontaneous combustion area of ​​residual coal, the sealing device needs to be not fixedly installed in the roadway, but moved freely according to the actual situation, and for the arched roadway, there is currently no sealing device designed for the arched roadway

Embodiment Construction

[0026] In order to better explain the present invention and facilitate understanding, the technical solutions and effects of the present invention will be described in detail below through specific implementation manners in conjunction with the accompanying drawings.

[0027] Such as Figure 1-2 As shown, a combined quick-blocking device for an arched roadway includes a temperature-sensitive airbag 1, a combined support 2 and an automatic inflation system. The combined support 2 is arranged inside the temperature-sensitive airbag 1 to support and fix the temperature-sensitive airbag 1. Air bag 1 is connected with automatic inflation system.

[0028] The temperature-sensitive airbag 1 is an airbag with an arched top, which can be closely combined with the inner wall of the arched roadway when it is inflated. Its material can sense the surrounding temperature, and it presents different colors according to the surrounding ambient temperature, realizing multi-stage discoloration, ...

Abstract

The invention relates to a combined rapid plugging device based on an arched roadway. The combined rapid plugging device comprises a temperature sensing air bag, a combined support and an automatic inflation system, the combined support is arranged in the temperature sensing air bag to support and fix the temperature sensing air bag, and the temperature sensing air bag is connected with the automatic inflation system; the temperature sensing air bag is an air bag with the arch-shaped top and can sense the surrounding temperature, different colors are shown according to different surrounding environment temperatures, and multi-section color changing is achieved; the automatic inflation system comprises a temperature sensor, a pressure sensor, a computer, an inflation device, an inflation solenoid valve and an exhaust solenoid valve. The device is simple in structure, rapid assembly and disassembly can be achieved, and automatic inflation and deflation can be achieved according to the set temperature and pressure.

Description

technical field [0001] The invention belongs to the technical field of coal mine production safety, in particular to a combined fast sealing device for an arched roadway. Background technique [0002] With the continuous development of the coal mining industry, safety issues cannot be ignored, especially the explosion caused by underground gas, which endangers the safety of workers; coal adopts retreat mining, and after mining, a goaf will be formed. Oxygen will enter due to external cracks, which will cause Spontaneous combustion of remaining coal in the goaf occurred. In order to cut off the air in the roadway from entering the goaf, a roadway sealing device is needed to avoid a large amount of mining coal combustion and gas gas entering the combustion area and causing an explosion, causing safety accidents and causing coal loss. However, due to the instability of the spontaneous combustion area of ​​residual coal, the plugging device is not fixedly installed in the roadw...
