Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a communication device using a hose with a built-in line.

b. Conventional technology The distance between the fire scene and the pump truck used to extinguish the fire varies depending on the situation at the scene. For example, in Tokyo, the distance between
0-150m, 120-250m is common in the Tama area.

On the other hand, according to regulations, the fire brigade must consist of seven people per pump truck, including a commander and one engineer.

Consists of water discharge and search volume.

However, in the event of an actual fire, it would be difficult to secure seven people to extinguish the fire, and it is more common for one person to do the same, even for water spraying.

Since the situation at the fire scene cannot be grasped by the engineers of the pump cars that supply water, the water supply according to the situation of the fire depends on ■messengers. ■By portable radio device. ■Using flowmeters, etc. are being taken, but ■There is no longer enough leeway for messengers,■
Portable radios are complicated due to their limited frequencies, and flowmeters only determine the amount of water being conveyed. There were drawbacks such as.

Therefore, a prior art technology (Japanese Patent Application No. 60-243641) in which a communication cable is built into a fire hose, and water sprayers and engine personnel communicate with each other through this communication cable to carry out appropriate fire extinguishing activities. It has been known.

C1 Problems to be Solved by the Invention However, in this prior art, water sprayers do not directly open and close valves or control engines, so it is not possible to carry out fire extinguishing activities in accordance with the site situation.

An object of the present invention is to solve the above-mentioned problems and provide a communication device using a hose with a built-in line that allows a single water sprayer to control the amount of water supplied, the water supply pressure, and notify the pump truck of the site situation.

d. Means for Solving the Problems In order to solve the above problems, the present invention connects a water spray nozzle and a pump truck via a hose with a built-in line in which a cable is arranged inside the hose, and connects the water spray nozzle to the line. A cable inside the line built-in type hose is drawn out through a tip adapter between the built-in type hose, and a communication device for communicating with the pump vehicle side and/or controlling the water supply control unit is connected to the cable.

e. Connect the water discharge nozzle and the pump truck via a hose with a built-in working circuit. A communication device is connected to the base end of the water nozzle via a tip adapter. Then, communication is performed with the pump truck side via the communication device.

On the other hand, a control fB section provided in the communication device opens and closes the valve on the pump car side and increases and decreases the engine output. In this way, water can be sprayed from the water spray nozzle at an amount and pressure depending on the fire situation.
