Principle of operation

When the tunnel entrance flood control emergency equipment is started from a static state, when the water level in a tunnel rises rapidly, water flows into the tunnel from a through hole at the bottom of the cylinder 203, the buoy 205 begins to rise rapidly, the inertia block 209 has inertia and rises slowly, the relative distance between the buoy 205 and the inertia block 209 is reduced, the upper magnet 208 and the lower magnet 206 are attracted, the inertia block 209 is in contact with the detection lower contact 207, the buoy 205 rises to the top of the cylinder 203 along with the continuous rise of the water level, the buoy contact 204 and the cylinder contact 212 are in contact and then the circuit is conducted, the ignition coil in the inflation chamber 102 ignites the gas generating agent in the inflation chamber 102, the air bag 101 begins to inflate, the valve head 110 is pushed to the direction away from the ground, the switch valve body 105 is conducted, and the clamping pin 113 in the push rod 111 is popped up.

Meanwhile, high-pressure gas in the plenum chamber 102 flows through the gas inlet 306 into the gas box 301 through the support gas pipe 315, the rotating arm 302 rotates, when the positioning pin valve 303 inside the rotating arm 302 moves to the pin groove 316, the positioning spring 312 pushes the positioning pin valve 303 into the pin groove 316, and the rotating arm 302 completes positioning. Meanwhile, the positioning pin valve 303 connects the cavity inside the gas box 301 with the gas tank 304, and the gas enters the supporting arm 308 and pushes out the secondary supporting arm 310 and the tertiary supporting arm 311 in sequence.

When the air bag 101 is filled with gas and the secondary supporting arm 310 and the tertiary supporting arm 311 are completely pushed out, the air bags 101 on two sides of the tunnel are in pressing contact, the internal air pressure of the inflation chamber 102 is equal to the internal air pressure of the air bags 101, the valve head 110 moves towards the ground direction under the action of the air valve spring 112, the bayonet pin 113 drives the contact seat 107 to move towards the ground direction, the upper contact 108 is in contact with the lower contact 109, the water pump 116 starts to start and pumps water entering the tunnel into the air bags 101, the gas in the air bags 101 flows out of the one-way valve body 117, when the internal water level of the air bags 101 is higher than the external water level, the water flow entering the tunnel is gradually cut off, and the air bags 101 on two sides are pressed more tightly, so that the waterproof effect is achieved.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
