Description

Water supply butt joint system for expressway tunnel fire-fighting robot

Technical Field

The utility model belongs to the technical field of the tunnel fire control technique and specifically relates to a water supply butt joint system for highway tunnel fire-fighting robot is related to.

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 providing a convenient and sufficient water source for the robot is urgently solved.

Disclosure of Invention

In order to solve the problem, the utility model provides a water supply butt joint system for highway tunnel fire-fighting robot specifically can take following technical scheme:

the utility model discloses a water supply butt joint system for highway tunnel fire-fighting robot, including the fire-fighting robot who sets up on the guide rail of tunnel top and set up the fire hydrant case on the tunnel lateral wall along longitudinal separation, be provided with the water pump in the casing of fire-fighting robot, water pump one end is connected with the squirt head, and the other end is connected with the fire hose of fixing on folding arm; the fire hydrant cabinet is characterized in that a self-locking cabinet door controlled by a remote control unlocking device is arranged on the fire hydrant cabinet, the remote control unlocking device is arranged at the tail end of the folding arm, a fire hydrant head in the fire hydrant cabinet is matched with a joint of the fire hose, and a one-way valve is arranged at the opening end of the fire hydrant head.

The folding arm comprises a plurality of sections of supporting arms, the supporting arms are connected through a steering joint, and elastic expansion joints are arranged on the supporting arms positioned at the middle sections.

When the folding arm is completely opened, the supporting arm at the tail end is coaxially arranged with the fire hydrant head in the fire hydrant box.

The utility model provides a water supply butt joint system for highway tunnel fire-fighting robot, simple structure, convenient to use, usable current fire hydrant supplies water, and safe and reliable has not only reduced earlier stage construction and later maintenance cost, can form good matching with fire-fighting robot in addition, is favorable to the robot to put out the fire source in the condition of a fire initial stage, effectively reduces the harm that tunnel conflagration caused.

Detailed Description

As shown in figures 1 and 2, a water supply butt joint system for highway tunnel fire-fighting robot, including setting up fire-fighting robot M on tunnel top guide rail and along vertical interval setting up the fire hydrant case N on the tunnel lateral wall, install water pump 1.1 in fire-fighting robot M's the casing, water pump 1.1 one end is connected with universal squirt head 1.2, and the other end is connected with fixes fire hose 1.4 on folding arm 1.3. As shown in fig. 3, the folding arm 1.3 includes a plurality of sections of supporting arms a made of refractory hard metal material, each section of supporting arm a is connected with each other through a steering joint b, except the head section and the tail section of supporting arms a, the other supporting arms a located at the middle section are provided with elastic expansion joints c, and the elastic expansion joints c can be made of hard elastic material such as spring and the like and are welded at two ends of the hard metal section. The steering joint b between the adjacent supporting arms a can control the extension of the folding arm 1.3, and stop when the folding arm is extended to a specific angle, and keep the folding arm 1.3 in a certain direction. Since the fire hose 1.4 is opened together with the folding arm 1.3, the length of the fire hose 1.4 should be designed with a certain margin.

The fire hydrant box N comprises a self-locking box door 2.1 and a fire hydrant head 2.2 located in the box body, wherein the self-locking box door 2.1 is an automatic side hung door driven by a motor, and the self-locking box door can be unlocked in a manual mode or an infrared remote control mode. The folding arm 1.3 end is installed and is had the remote control unlocking means with fire hydrant case N automatic vertical hinged door assorted, and this unlocking means contains infrared signal transmitter and distance detector. The joint of the fire hose 1.4 is matched with the fire hydrant head 2.2.

Normally, a self-locking box door 2.1 of the fire hydrant box N is in a closed locking state (see figure 4), when a fire disaster occurs in the tunnel, the fire-fighting robot M moves to the fire hydrant box N closest to a fire source along a guide rail at the top of the tunnel, and the folding arms 1.3 are unfolded section by section until the tail section supporting arms a are equal to and coaxial with a fire hydrant head 2.2 in the fire hydrant box N; then, a remote control unlocking device on the tail section supporting arm a sends a signal to the self-locking box door 2.1, so that the self-locking box door 2.1 is unlocked and automatically opened under the action of a motor; after the self-locking box door 2.1 is opened, the joint of the fire hose 1.4 continues to move forwards until the joint is clamped with the fire hydrant head 2.2; and then, the water pump 1.1 is started, so that the universal water gun head 1.2 sprays water to an ignition point to extinguish fire. In addition, the fire hydrant box door can also be unlocked and opened manually.
