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 fast blocking device based on an arched roadway, which includes a temperature-sensitive airbag, a combined bracket and an automatic inflation system, the combined bracket is arranged inside the temperature-sensitive airbag to support and fix the temperature-sensitive airbag, the temperature-sensitive airbag and the automatic inflation system connection. The temperature-sensing airbag is an airbag with an arched top, and its material can sense the surrounding temperature, and present different colors according to different surrounding ambient temperatures to achieve multi-stage color change. The automatic inflation system includes a temperature sensor, a pressure sensor, a computer, an inflation device, an inflation solenoid valve, and an exhaust solenoid valve. The invention has a simple structure, can realize fast assembly and disassembly, and can realize automatic inflation and deflation 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...
