[Conventional technology]

2. Description of the Related Art Conventionally, a self-propelled fire extinguishing vehicle controlled wirelessly controls its steering wirelessly.

[Problems to be solved by the invention]

The wirelessly controlled self-propelled fire extinguishing vehicle has a feature that a self-propelled fire extinguishing vehicle can be extinguished by approaching a place where no one can approach. However, in fire scenes, etc., several fire trucks gather to perform radio communication and cause interference, and in radio communication with limited frequency, radio waves are diffused by buildings, trees, mountains and other obstacles, and accurate Accurate remote control was difficult due to difficulty in reaching. For this reason, other than the operation of the vehicle body, it is difficult to remotely control the direction of the water discharge gun, remotely control the valve by mounting a plurality of water discharge guns, and the like.

On the other hand, when a conductor is connected to a self-propelled vehicle and an electric signal is sent from the rear through the conductor to remotely control the vehicle, tangling of the conductor,
There is a problem of disconnection, especially at a fire site, where other fire trucks and firefighters are confused, so thin cables are easily disconnected, and hooked up and the connection parts are pulled out or destroyed. There is a possibility that a secondary disaster (gas explosion due to short circuit, oil fire, etc.) may occur due to electric leakage, which is a major drawback.

In view of these circumstances, the present invention has been developed for the purpose of providing a remotely controlled self-propelled fire extinguishing vehicle that does not have a disconnection or a danger while using a wired power supply without using a radio.

[Means for solving the problem]

This idea is to solve the above problems and achieve the purpose,
On the base provided with a traveling mechanism such as a radio rail at the bottom, a hose joint, an automatic controller, a water discharge mechanism and a drive mechanism are mounted, and a conductive hose is connected to the hose coupler, and the conductive hose is installed inside the hose. The conductive wire is installed in a floating state, and the tip of the conductive wire is fixed in a waterproof manner to the fittings fixed to both ends of the hose main body, and the conductive wire terminal tip is exposed to the tip of the connecting fitting to be connected. The hose coupler is configured to be connectable to the conductive terminal of the target connection fitting, the hose coupler communicates with the water discharge mechanism, the conduction repeater electrically connects the drive and the automatic controller, and the conduit communicates with the water conduit. The water discharging mechanism includes a connecting portion for connecting a conductive terminal of the repeater to a conductive hose, and the water discharging mechanism supports the water discharging gun on the rotating lifting column so that the water discharging gun can be freely raised and lowered by a driving device, and connects the water discharging gun and the water pipe with water. And the automatic controller and each driving machine Technical means of remotely controlling a fire extinguishing vehicle that performs pneumatic connection, sends water from the outside to the water spray gun via the conductive hose, and transmits power and signals to the conductive repeater by wire to control vehicle body driving and water discharging operation. Was taken.

[Action]

This invention configured as described above has the following operation.

Although the conductive hose is a hose for water supply, it has a built-in conductive wire for transmitting control signals to the power supply and the controller inside, and the end of the conductive wire is connected to the connection fitting in a waterproof manner, There will be no leakage unless the wire breaks. Since the conductive wire is floating inside the hose except that both sides are fixed to the connecting fittings, when the hose is folded, the internal conductive wire becomes the full width of the hose along the folded surface of the hose. The conductors do not bend like a hairpin curve because they are separated from each other in a vertical direction.

By connecting several conductive hoses to, for example, a water outlet of a fire engine and connecting a terminal of a conductive wire to a power source and a control signal launcher, the hose is connected to a hose coupler of a remote control fire extinguishing vehicle via the conductive hose. Water can be delivered as well as power and signals.

Therefore, the control signal is started from the fire engine side through the conductive wire in the conductive hose to activate the automatic controller of the remote control fire extinguishing vehicle, for example, controlling the driving and steering of the driving machine to the site where the fire should be extinguished To progress. Next, it is possible to control each drive unit of the water discharge mechanism, for example, the raising / lowering of the turning elevating column, the turning drive, and the switching valve opening / closing operation. As a result, it is possible to surely remotely control the driving sources such as the running, the steering, the water discharge direction, and the angle of the vehicle body.
