Background

In recent years, with the development of tunnel excavation technology, tunnels with the length of three to four kilometers are common, and ultra-long tunnels with longer length, even more than ten kilometers, are gradually built, so that the traffic trip of people is greatly facilitated. However, the highway tunnel is usually far away from the city where people live, once a fire occurs, it is difficult for the fire rescue personnel to quickly arrive at the scene, and most of the ordinary drivers and conductors near the fire point waste the gold time for fighting the fire at the initial stage because the fire protection facilities in the tunnel are not used. In addition, because the tunnel is long and narrow and is relatively closed, the trapped vehicles are easy to cause traffic jam and paralysis, so that fire fighters and rescue personnel are prevented from entering the scene, and the disaster situation is further expanded. Therefore, the fire-fighting robot which eliminates traffic obstacles and runs along the guide rail arranged at the top of the tunnel becomes a current research hotspot, and accordingly, the problem of urgent need to be solved by arranging a water supply network and providing a convenient and sufficient water source for the robot.

Detailed Description

As shown in figures 1 and 2, a water supply system for highway tunnel fire-fighting robot, including cyclic annular fire control water supply person in charge 1, cyclic annular fire control water supply person in charge 1's straight tube section sets up respectively in the weak current cable pit in the outside of two-way tunnel (about the line tunnel), and communicate the cyclization beyond the tunnel exit. The annular fire-fighting water supply main pipe 1 is arranged in the cable trench, so that the civil engineering investment is saved, and the common fire hydrant and the water supply branch pipe 2 matched with the fire-fighting robot can be simultaneously connected, so that the system utilization rate is improved, and the equipment investment is saved. The water supply branch pipes 2 are arranged on the straight pipe section of the annular fire-fighting water supply main pipe 1 at intervals. Each water supply branch pipe 2 consists of a hard connecting pipe 2.1, a flexible pipe 2.2 and a hard joint pipe 2.3, wherein the hard connecting pipe 2.1, the flexible pipe 2.2 and the hard joint pipe are sequentially connected from bottom to top, the flexible pipe is embedded in the side wall of the bidirectional tunnel, and the hard joint pipe corresponds to the height of a water supply port of the fire-fighting robot.

An electric control valve 2.4 positioned in the valve well is arranged on the hard connecting pipe 2.1, and the electric control valve 2.4 can be automatically opened to supply fire water after receiving a signal that the fire-fighting robot and the hard joint pipe 2.3 are installed; in order to facilitate installation and maintenance, an access door is also arranged on the valve well of the electric control valve 2.4. The flexible pipe 2.2 positioned in the side wall pipe ditch can better fit the radian of the side wall of the tunnel, so that the problem that more joints are needed when rigid pipes are used is avoided, and the construction and installation process is simplified; in addition, the outside of the flexible pipe 2.2 is also coated with a refractory material layer, so that the safety of the water supply branch pipe in fire is ensured. The open end of hard joint pipe 2.3 is installed with check valve 2.5, and under normal conditions, check valve 2.5 is closed (see fig. 3), and when the conflagration appeared, fire-fighting robot M people moves to the hard joint pipe 2.3 department near the ignition along the top rail, and its water supply mouth Q pushes up to check valve 2.5, and hard joint pipe 2.3 links to each other with robot water supply mouth Q after check valve 2.5 pressurized is opened (see fig. 4), waits to supply water after electric control valve 2.4 opens and puts out a fire.

The annular fire-fighting water supply main pipe 1 is connected with an ordinary-high pressure fire-fighting water supply system, the ordinary-high pressure fire-fighting water supply system comprises a low-level water tank 3.2 supplied with water by a deep-well pump 3.1, the low-level water tank 3.2 is connected with a high-level water tank 3.4 through a fire pump 3.3, and the high-level water tank 3.4 is connected with the annular fire-fighting water supply main pipe 1 through a sewer pipe 3.5. When high-order pond 3.4 keeps when setting for the water level above, because gravitational potential energy, can keep sufficient water pressure in the cyclic annular fire control water supply main pipe 1 in order to supply the fire control water, at any time, only need hard adapter tube 2.3 to be connected with robot feed water mouth Q and target in place, automatically controlled valve 2.4 opens the back and can supply water and put out a fire, need not to start deep-well pump 3.1 and/or fire pump 3.3 temporarily, has saved pump start-up time, safe and reliable more. Correspond respectively in above-mentioned low level pond 3.2 and the high-order pond and install first level sensor 3.6 and second level sensor 3.7, the signal output part of first level sensor 3.6 and second level sensor 3.7 links to each other with the signal input part of singlechip respectively, the control output part of singlechip links to each other with deep-well pump 3.1 and fire pump 3.3's control input part respectively. When the water levels in the low-level water tank 3.2 and the high-level water tank 3.4 are lower than the preset values, the first liquid level sensor 3.6 and/or the second liquid level sensor 3.7 can send signals to control the deep-well pump 3.1 and/or the fire pump 3.3 to be started, and sufficient water quantity in the normal-high pressure fire-fighting water supply system is guaranteed to correspond to tunnel fire.
