Problems solved by technology

However, the air supply device of the existing rescue cabin lacks necessary protection measures. When the tunnel collapses, it is easily damaged by falling gravel or closed by broken stone slabs, so that the air supply device cannot provide air for the rescue cabin. Supplementary air, resulting in a significant drop in the use of the rescue chamber

Abstract

The invention discloses a high-safety air supply device of a tunnel construction rescue capsule. The high-safety air supply device comprises an air supply box and a rescue capsule side wall; the rescue capsule side wall is connected with the air supply box in a penetrating mode; the upper portion of the rescue capsule side wall is fixedly connected with an outer protective cover matched with the air supply box; a plurality of fixing rods are evenly arranged at the top end of the outer protective cover; the ends, far from the outer protective cover, of the fixing rods are fixedly connected with the rescue capsule side wall; an air suction pump is fixedly installed on the top wall of an inner cavity of the air supply box; the air inlet end of the air suction pump is in through connection with the top wall of the air supply box through an air suction pipe; the air outlet end of the air suction pump is in through connection with a filter cartridge through a connecting air pipe; and the air outlet end of the filter cartridge is in through connection with an air outlet pipe. Through the arrangement of the fixing rods and third reinforcing rib plates, the firmness of the outer protective cover fixed to the rescue capsule side wall can be greatly improved, the outer protective cover can be effectively used for shielding broken stones falling from collapse of a tunnel for the air supply box, and the safety of the air supply box can be protected to the maximum extent; and by virtue of the gap between the outer protective cover and the air supply box, sufficient air can be provided for the operation of the air suction pump.

Description

technical field [0001] The invention relates to the technical field of rescue chamber air supply equipment, in particular to an air supply device for a tunnel construction rescue chamber with high safety. Background technique [0002] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills; in order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea; in order to meet the needs of railways passing through large cities, it is called a tunnel. Those that pass underground are called urban tunnels. [0003] In order to provide temporary refuge space and living materials for those trapped in the ...
