【考案の詳細な説明】
一般に消防ポンプ車による送水操作は、ホース
の延長本数や揚程等を考慮して、放水口コツクを
手動で開いた後に延長ホース先端に結合した放水
ノズル部の圧力が所定の圧力になるようにポンプ
車の圧力計を見ながらエンジンスロツトルを手動
操作してポンプ回転数の調整を行い送水基準盤等
で求めた適正なポンプ圧力に設定している。[Detailed explanation of the invention] In general, when water is supplied by a fire pump vehicle, the pressure of the water nozzle connected to the end of the extension hose is set to a predetermined level after the water outlet is opened manually, taking into consideration the number of extended hoses and the pumping height. The pump rotation speed is adjusted by manually operating the engine throttle while watching the pressure gauge on the pump truck so that the pump pressure is set to the appropriate pump pressure determined from the water supply reference board.

つた場合に消防ポンプ車のポンプ圧力と放水ノズ
ル部の圧力との間に様々な圧力差を生じるため、

を計算しなければならない。 In firefighting activities, the friction loss of running water varies depending on the number of extended hoses, and when conditions such as lift height change, various pressure differences occur between the pump pressure of the fire pump truck and the pressure of the water discharge nozzle.
The set pump pressure must be calculated according to the length of the hose line.

のが現状である。 In addition, when nozzles with different diameters are connected to each water outlet, in order to discharge different flow rates from multiple water outlets, it is necessary to adjust the opening degree of the manual water outlet in addition to adjusting the pressure. However, since this operation is extremely difficult, it is currently prohibited to use nozzles with extremely different flow rates because it is dangerous.

能にしているにすぎない。 Since pressure control during water supply operations using pumps has good responsiveness, various automatic pump pressure control devices using electronic governors, solenoid valves, etc. have been devised as automatic control devices for fire pumps. In either case, the control means is only based on pressure, so they are not sufficient for automatic control of fire pumps, and only allow automation of a small part of the water supply operation.

御できるようにした。 The nozzle currently used by the fire brigade has a nozzle pressure of 3.
Kg/cm 2 and 500/min type and nozzle pressure 15
Since two types of Kg/cm 2 and 200/min types are often used, the flow rate setting devices 5 1 and 5 2 are used in the example.
It consists of five buttons: 500/min, 200/min, increase, decrease, and stop, and can be controlled from the position of the water spray nozzle at the end of the extension hose using a captire cable.

る。 When there is no flow rate setting from the flow rate setting device 5 1 , 5 2 of each water outlet, the engine 8 is in an idling state, and each water outlet pot 4 1 , 4 2 is in a closed state. Flow rate setting signal from flow rate setter 5 1 is sent to calculator 7
Based on the output value of the calculation result, the water outlet cock 41 opens to the planned opening degree via the control mechanism of the converter 11 and the piston 101 , and water begins to flow into the water outlet piping. Based on the output value of the calculation result, the throttle for controlling the rotation speed of the engine 8 is driven via the converter 11 and the controller 9 so that the flow rate value of the flow rate detector 31 becomes the set flow rate, and the pump rotation is controlled. This makes it possible to automatically control the water flow rate.

できる。 The effect of the device according to the present invention is that the pump makes the water supply operation very easy and quick, and allows for proper water discharge. Additionally, water discharge equipment with different flow rates can be used safely at the same time. Furthermore, since the flow rate can be set using an electrical signal, the pump can be operated from a flow rate setting device that is integrated with a water discharging device located far from the pump vehicle using communication means, allowing quick pump operation. It is possible to achieve greater efficiency and labor savings.

For example, if the hose line is crushed due to some kind of obstruction, the flow rate will not increase even though the flow rate has been set, so this condition can be confirmed by a computer, and the control signal will be used to automatically close the water outlet. can be closed. Alternatively, control such as lowering the engine speed can be performed. The method is to use pressure detector 1
Abnormal pressure can be controlled by inputting the signal No. 3 to the computing unit.
