[0020] Specifically, a flow meter 18 is provided on the pump liquid outlet pipeline 29 at the outlet end of the fire pump 19 ; wherein the flow meter 18 can monitor the liquid output volume supplied by the fire pump 19 in real time.
[0021] Specifically, the pump liquid outlet pipeline 29 is also connected to a water tank water filling pipeline 23 , the water tank water filling pipeline 23 is connected to the inlet of the water tank 21 , and a water tank water filling valve 17 is provided on the water tank water filling pipeline 23 .

[0025] In combination with the above technical scheme and the accompanying drawings, the method of use and the working principle of the utility model are explained as follows: (1) When encountering an ordinary fire in a high-rise residential building, first control the arm of the fire truck to lift, aim the fire cannon 1 at the top of the arm at the fire extinguishing point, and then use the fire pump 19 to pump water. Since the water stock in the water tank 21 and the foam stock in the foam tank 22 are limited, the water tank foam truck is connected to the water tank external water supply valve 6 and the external foam liquid supply valve 10 respectively, so that water and foam liquid can be continuously injected into the water tank 21 and the foam tank 22, which can ensure that the fire truck has a continuous fire extinguishing source; this type of fire extinguishing method is called automatic water fire extinguishing, and its water pumping pressure depends on the pressure of the fire pump 19 of the fire truck. If a fire occurs in a low-rise civilian building, one end of the water hose can be directly connected to the external gun liquid outlet valve 3, and a manual simple water cannon can be installed on the other end of the water hose. The fire pump 19 and the external gun liquid outlet valve 3 can be turned on, and then the manual simple water cannon can be turned on to directly extinguish the fire. Therefore, the external gun liquid outlet valve 3 and its liquid outlet pipeline are generally installed in the pump room and arranged in the same space as the fire pump 19.
[0026] (2) When encountering a large fire, first control the arm of the fire truck to lift, aim the fire monitor 1 at the top of the arm at the fire extinguishing point, and then connect the external water suction valve 20 and the external foam liquid valve 11 on the pump water inlet pipe 25 to the water tank foam truck. The fire extinguishing source in the water tank foam truck can be directly sucked in and provided to the fire pump 19, and then the fire extinguishing source provided by the water tank foam truck is ejected by the fire monitor 1 through the fire pump 19. In this way, the input water pressure of the water tank foam truck and the operation of the fire pump 19 of the fire truck can be used to increase the pressure, and secondary pressurization can be performed, which can enable the fire truck to extinguish the fire continuously and effectively. This fire extinguishing method is called coupled water supply fire extinguishing.
[0027] (3) In addition, when a fire occurs in a scene where many fire hydrants are arranged (for example, a fire in a petroleum and petrochemical enterprise), the fire hydrant at the fire extinguishing scene can be directly connected to the fire cannon direct external water supply valve 2 on the fire cannon direct external water supply pipeline 28. After the fire hydrant is opened, it has a certain water pressure, which can directly drive the fire cannon 1 at the top of the boom to perform fire extinguishing operations. In this way, the water pressure does not need to be pressurized twice. When the fire extinguishing point at the fire extinguishing scene is relatively fixed, the water source can be connected in a relatively simple way to quickly extinguish the fire.
[0028] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the embodiments of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
