However, in such a conventional fire extinguisher equipped with a self-propelled water sprinkler, the self-propelled water sprinkler is designed to move while extending a hose connected to a fire hydrant or the like. Therefore, there was a problem that the movement distance was determined by the length of the hose mounted on the self-propelled water discharge device, and the activity range was restricted.

Therefore, it is conceivable to lengthen the hose to be mounted in order to widen the range of activity, but there is a problem that the weight and size of the device are increased, and the hose becomes difficult to move in a narrow place.
In addition, if water is supplied from a hose, the hose becomes so stiff that it cannot be moved unless it is removed.
Further, when a plurality of self-propelled water discharge devices are used, there is a possibility that the hose used in another self-propelled water supply device may be hindered and unable to move.

The present invention has been made in view of the above-mentioned conventional problems, and there is provided a self-propelled fire extinguisher which has no restriction on the range of activity in the fire extinguishing area and which is small and lightweight. The purpose is to provide fire extinguishing equipment provided.

A self-propelled water discharge device is provided.

Here, each of the plurality of water supply devices installed in the guard area is provided with an electric valve, and the water discharge device controls the opening of the electric valve provided in the water supply device to which the water supply port is connected. In addition, the travel pattern from the reference position where the water discharge device is resident to the installation position of the plurality of water supply devices is registered in advance, and by specifying the installation position of the target water supply device, the corresponding travel pattern is selected and automatic travel is performed. Then, when the user reaches the target position, his / her water supply port can be connected to the water supply device.

[0009]

According to the fire extinguishing system equipped with the self-propelled water discharger of the present invention having such a structure, the self-propelled water supply device can be installed near the origin of the fire by the remote control such as radio. By moving and connecting its own water supply port to a water supply device that is fixedly installed on the lower part of the wall surface, etc., it receives pressurized supply of fire extinguishing water from the pump equipment, and a water gun towards the fire source caught by a TV camera etc. Can be discharged from.

Therefore, it is not necessary to mount the hose on the self-propelled water discharger and move it while extending the hose, and it is possible to reduce the size and weight of the water discharger. In addition, the range of activity of the self-propelled water sprinkler becomes possible throughout the fire extinguishing area of the building where the water supply system is installed. Furthermore, since the installation location of the water supply system in the building is determined in advance, it is possible to register the travel pattern from the reference position such as the garage where the self-propelled water supply system is resident to each water supply system, and to prevent fires. Select the corresponding driving pattern by specifying the water supply device that is closest to the location of occurrence,
It is possible to automatically move to and connect to the water supply device.

For this reason, the operator does not need to manually operate the self-propelled water sprinkler to connect to the location of the water supply device, and the operator does not have to take time to prepare for extinguishing the fire. Firefighting can be started by discharging water.
