First aid equipment for flood control at tunnel entrance

Abstract

The invention belongs to the field of first-aid equipment for flood control at tunnel entrances, and in particular relates to first-aid equipment for flood control at tunnel entrances. There are multiple inflatable holes, the connection surface between the inflatable chamber and the airbag is fixed with a switch valve body, and a water pump is fixed on both sides of the inflatable chamber perpendicular to the direction facing the airbag. The upper part of the side is fixed with a one-way valve body, and the sliding sleeve inside the one-way valve body is provided with balls, and the ball and the one-way valve body are connected by a one-way spring, and a gas ignition coil is installed inside the inflatable chamber; The component is set inside the inflatable chamber, which is responsible for detecting the rising speed and height of the water level, and triggers the ignition coil to make the inflatable chamber work; the airbag support component, which is set inside the inflatable chamber, is responsible for supporting and guiding the inflated airbag.

Description

technical field [0001] The invention belongs to the field of flood control emergency equipment at the tunnel entrance, in particular to a flood control emergency equipment at the tunnel entrance. Background technique [0002] Although the tunnel entrance is generally equipped with waterproof facilities, in the event of heavy rain, a large amount of rainwater still flows down from the top of the mountain and pours into the tunnel entrance, or the tunnel cave is in a relatively low-lying area, causing water to accumulate in the tunnel, the vehicle is turned off, and people are killed. Trapped in the tunnel, it will bring inconvenience to people's travel, and sometimes the speed of the accumulation of water will cause the people in the tunnel to be unable to evacuate in time, posing a greater threat to the safety of people's lives.

AI Technical Summary

Problems solved by technology

[0002] Although the tunnel entrance is generally equipped with waterproof facilities, when there is heavy rain, there is still a large amount of rainwater flowing down from the top of the mountain and pouring into the tunnel entrance, or the tunnel cave is located in a relatively low-lying area, resulting in water accumulation in the tunnel, vehicles stalling, and people being trapped. Trapped in the tunnel, it brings inconvenience to people's travel, and sometimes the speed of accumulated water will cause the people in the tunnel to be unable to evacuate in time, which poses a greater threat to the safety of people's lives

[0003] The existing waterproof methods generally use sandbags to block or block through baffles at zero time, which is inconvenient to use, or the rescuers use water pumps to pump water into the tunnel, but it takes time for the rescuers to rush to the tunnel, so there is an urgent need for an automatic detection method. Tunnel water level and rapid and efficient waterproofing of tunnel entrance flood control first aid equipment
