Description
Technical Field
The invention belongs to the technical field of emergency plugging equipment, and particularly relates to an emergency plugging door.
Background
The safety protection of the coal mine is very important. The mine needs to be treated in an emergency in the shortest time after danger occurs, so that the life safety of miners is ensured, and two methods are generally adopted: firstly, hiding the escape capsule; and secondly, immediately plugging the dangerous area and rapidly withdrawing. At present, the rescue capsule and the refuge room are also developed and popularized in China, but the construction cost of the rescue capsule and the refuge room is relatively high and the refuge room is not easy to popularize, and at present, the rescue capsule and the refuge room are still rapidly evacuated by organization miners after danger occurs in most mines. The space in the mine tunnel is narrow, the track is arranged in most mine tunnels, the road is narrow and uneven, and great inconvenience is brought to the evacuation of miners, so that an automatic device capable of rapidly sealing a dangerous area after the dangerous situation occurs is urgently needed. The coal mine safety product needs to be simple to operate, can rapidly seal a roadway, has good sealing performance and strong compression resistance, creates a favorable environment for treating a dangerous area, and also wins precious time for miners to escape from the dangerous area.
At present, there are approximately 3 plugging methods for mine roadways at home and abroad, and the plugging methods are organic foaming material plugging, traditional material plugging and external air source air bag plugging. At present, the rapid temporary sealing at home and abroad still adopts multi-purpose wood board sealing, wood pile sealing, concrete sealing wall, brick mixing sealing wall or stone wall and the like, which belong to the traditional material sealing. The method is only adopted when the wall closing construction is required to be permanently closed, and the transportation in the roadway is difficult and the construction speed is low, so that the method is obviously not preferable for temporary closing in emergency rescue. For the blocking of an external air source air bag, the external air source air bag type airtight is developed in countries such as German, russian, wave and law, and the material of the air bag type airtight is made of cloth-based fireproof paint, asbestos cloth and other temperature-resistant materials, and the air bag type airtight is inflated by compressed air; parachute type sealing is developed in japan, and wind is blown up by tunnel wind current. The method is time-consuming and labor-consuming, and can not simply, quickly and effectively automatically plug the roadway. At present Wang Rui, liu Xin and Li Huisheng propose a mine roadway plugging method without an external air source, which is based on the principle that in a closed air bag, when sodium bicarbonate solution and aluminum sulfate solution are mixed together, CO 2 gas is generated by reaction, the air bag is rapidly inflated to be used for plugging a channel, however, the method has the major defect that the air bag is easily damaged by impact of dangerous sources such as flying stones, gas explosion flame and the like, and the safety and reliability are low.
The traditional mechanical gate is blocked, a channel cannot be rapidly and safely blocked under the emergency condition, the reliability and the safety are low, particularly for a mine channel, the working condition of the traditional mechanical gate is bad when sudden disasters (water burst, gas burst and the like) occur, the reliability and the safety are reduced, so that the influence on emergency refuge is extremely large, the inventor synthesizes various factors, comprehensively considers, creatively provides an emergency blocking door, and seals the sudden disasters on one side of the channel when the emergency refuge occurs, ensures that the other side is not affected by the disasters, and provides enough time and space for emergency refuge escape.
