Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher for extinguishing a fire in a tunnel.

[0002]

2. Description of the Related Art Generally, a tunnel is provided with a large number of fire detecting devices for detecting a fire and a plurality of sprinklers which operate in response to fire information from the fire detecting devices at predetermined intervals.

When a fire occurs in a tunnel, the fire is detected by a fire detector installed near the fire site, and a fire extinguishing liquid such as water or a fire extinguisher is ejected from a sprinkler near the fire site. In addition to automatically extinguishing fires, alerts are sent outside the tunnel.

However, if fire extinguishing activities are performed by sprinklers, a large number of sprinklers must be installed near the ceiling in the tunnel, which requires large-scale piping, which makes installation and maintenance difficult. There is a problem that costs are high. In addition, since water is sprayed near the fire spot by a sprinkler fixed in advance, there is a problem that water cannot be concentratedly discharged at the fire spot and a vehicle fire cannot be completely extinguished.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a tunnel fire extinguisher having a higher fire extinguishing ability, which is easy to lay and maintain.

[0006]

In order to achieve the above object, the present invention relates to a tunnel fire extinguishing system, comprising: a pair of water feeding means provided along a tunnel for flowing a fire extinguishing liquid such as water or a fire extinguishing agent; Water intakes provided at predetermined intervals in the means,
The fire extinguishing robot includes a fire extinguishing robot having a water discharging device that travels along a water feeding means as a track, and a water intake device provided in the fire extinguishing robot and connected to the water intake port to flow the fire extinguishing liquid in the water feeding means to the water discharging device.
