[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0036] The present application aims to provide a water supply control system, a fire truck and a water supply control method to solve the problems of the prior art, to stabilize water supply and improve work efficiency.

[0037] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0038] At present, during the fire fighting operation, sometimes natural water sources such as rivers and lakes need to be used. When natural water sources are used, because of the complex environment and terrain of the water source, it is inconvenient for the fire truck to take water. In order to facilitate water taking, a special fire truck is generally needed as a water taking truck, which is fixed near the water source to continuously take water from the water source and supply the taken water to other fire trucks, so that other fire trucks no longer need to temporarily lay water taking belts, thereby improving the work efficiency of other fire trucks. However, the existing fire truck water supply system often needs to be manually operated and adjusted, which is difficult to adapt to complex fire fighting scenes, and is prone to problems such as unstable water supply, water and energy waste, etc. In order to solve this problem, the first object of the present application is to provide a water supply control system, as shown in the figure, which comprises a water tank 1; a water taking pump 2 is connected to a water source at one end and is connected to a water inlet of the water tank 1 through a pipeline at the other end; a fire pump is connected to a water outlet of the water tank 1, for injecting water in the water tank 1 into other fire trucks or for supplying water to other devices; a data acquisition device is arranged on the water tank 1, the fire pump and the pipeline, and can acquire water level information of the water tank 1, water flow and water pressure information of the fire pump; a controller 3 is connected with the data acquisition device and a plurality of water taking pumps 2, and can control the water flow of the water taking pump 2 and the fire pump according to the acquisition information of the data acquisition device. Figure 1 The present application realizes automatic adjustment of water supply and taking flow through intelligent control, ensures the stability of the water level of the water tank 1, avoids waste of water and energy, and adapts to complex fire fighting scenes. The operation of the operator is simplified, the work intensity is reduced, and the efficiency and reliability of the fire fighting operation are improved. The water supply control system is used as a transfer between the water source and the water receiving fire truck, and the water supply control system quickly supplies water to the water receiving fire truck, without the need for temporary laying of water belts on site, which is simple and fast, and greatly improves the water supply efficiency. The water supply control system can supply water to multiple water receiving fire trucks at the same time, meets the water supply demand of large-scale fire fighting operation, and enhances the ability of fire rescue.

[0039] In an embodiment, in order to reduce weight and simplify structure, the fire pump can be arranged on the water receiving fire truck.

[0040] In an embodiment, the water pump 2 is arranged in the water source, and the water outlet of the water pump 2 is communicated with the water inlet of the water tank 1 through a pipeline. The controller 3 can control the number of water pumps 2 to be started according to the information collected by the data acquisition device, and control the water supply flow of the fire pump and the water pump 2 in the started state. Through the control of the number of water pumps 2 to be started and the water supply flow, the water level of the water tank 1 can be stabilized, and the waste of water and energy is avoided, and the complex fire fighting scene is adapted. The control of water quantity can be realized by adjusting the working power of the water pump 2 or the fire pump. In other embodiments, an electromagnetic valve can be arranged on the pipeline connected with the water pump 2 and the fire pump, and the water supply flow can also be adjusted by controlling the opening of the electromagnetic valve.

[0041] The data acquisition device of the embodiment includes a liquid level sensor 4, a flow sensor and a pressure sensor. The liquid level sensor 4 is arranged in the water tank 1 and can monitor the liquid level in the water tank 1 in real time. The water inlet of the water tank 1 is provided with a flow sensor, and the water outlet of the fire pump is provided with a flow sensor and a pressure sensor. In the fire fighting operation, multiple fire trucks take water from the water tank 1 at the same time, which causes the water level of the water tank 1 to drop rapidly. When the liquid level drops to a set position, the liquid level sensor 4 feeds back a signal to the controller 3, and the controller 3 immediately issues an instruction to start the third water pump 2 (two water pumps have been started before), thereby increasing the water injection amount. With the change of water intake, the water level of the water tank 1 gradually stabilizes. During this period, the flow sensor detects that the water supply flow fluctuates, and the controller 3 adjusts the output of the fire pump in time to keep the water supply pressure within a stable range, thereby ensuring the smooth progress of the fire fighting operation.

[0042] The second object of the present application is to provide a fire truck, as shown in Figure 2 、 Figure 3 、 Figure 4 The second object of the present application is to provide a fire truck, as shown in

[0043] In an embodiment, the outer water injection pipeline 6 is provided with an upper water supply opening 8, which is located on the side of the switching valve away from the second outer water injection opening, and the upper water supply opening 8 is arranged close to the switching valve on the outer water injection pipeline 6. A cover plate is fixedly sealed at the upper water supply opening 8, and the upper water supply opening 8 can be connected with an upper water supply pipe 9 after the cover plate is opened. The end of the upper water supply pipe 9 away from the outer water injection pipeline 6 is used to externally connect other fire trucks. In this embodiment, when the roof switching valve 7 is in the open state and the upper water supply opening 8 is in the closed state, water can be injected into the water tank 1 through the outer water injection pipeline 6. The water outlet at the bottom of the water tank 1 is connected with a tank lower water supply pipeline, and the tank lower water supply pipeline is connected with a lower water supply opening 10. The lower water supply opening 10 is used to externally connect other fire trucks. The water receiving fire truck uses a water suction pipe to connect the water outlet at the bottom of the water tank 1, and starts the fire pump on the vehicle to directly take water from the water tank 1. When the roof switching valve 7 is in the closed state and the upper water supply opening 8 is in the open state, the water receiving fire truck parked nearby can directly receive water from the system after opening the tank body manhole cover on the roof. This scheme does not need to temporarily lay water hoses on site, and the water receiving operation is faster. In an embodiment, the fire pump is connected to the tank water outlet pipeline of the water tank 1, and is used to inject water in the water tank 1 into other fire trucks or to supply water to other devices.

[0044] In addition, in an embodiment, the present application can also realize the function of simultaneously supplying water to multiple water receiving fire trucks. The water taking pump 2 is started, water is taken through the water injection opening and connected water hose, the switching valve 7 is adjusted to the appropriate position to ensure that the outer water injection pipeline 6 is in communication with the water tank 1, the water tank 1 is filled with water, and then the switching valve 7 is adjusted to close the outer water injection pipeline 6 and the water tank 1, or to reduce the communication channel between the outer water injection pipeline 6 and the water tank 1. At this time, the upper water supply opening 8 is opened to communicate with the upper external water supply device. Since four water supply openings (two upper and two lower) are symmetrically arranged on the left and right sides of the vehicle, water can be simultaneously supplied to four water receiving fire trucks. Two of the water receiving fire trucks take water through the lower water supply opening 10 of the water tank 1, and the other two take water through the upper water supply opening 8 on the roof and the upper external water supply device. The entire water supply process does not need to lay temporary water hoses, and only a few minutes are needed to complete the connection and water supply, which greatly improves the rescue efficiency.

[0045] The present application also provides a water taking and supplying control method, which comprises the following steps:

[0046] The water taking and supplying control system is arranged near a water source;

[0047] The water taking pump 2 is started to inject water into the water tank 1, and the fire pump is started to sequentially supply water to other fire trucks;

[0048] Or the water taking pump 2 is started to inject water into the water tank 1, and the tank lower water supply pipeline and the lower water supply opening are used to supply water to other fire trucks;

[0049] Or start the water pump 2, do not inject water into the water tank 1, directly through the outer water injection line, the upper water supply pipe for other fire vehicles to supply water;

[0050] According to the liquid level information of the collecting water tank 1, the water flow and pressure information of the fire pump, the opening number of the water pump 2, the water flow of the fire pump and the water flow of the water pump 2 in the opening state are controlled; in the process of fire fighting, the flow sensor and the pressure sensor detect the water supply flow and pressure of the fire pump outlet in real time, and transmit the data to the controller 3 through the CAN bus, and the CAN bus and the controller 3 are prior art. The liquid level sensor 4 detects the liquid level height of the water tank 1 in real time, and also transmits the data to the controller 3. The controller 3 analyzes and processes these data, and when the water supply flow, pressure or water tank 1 liquid level fluctuates, the controller 3 automatically calculates the flow of the water pump 2 and the fire pump that need to be adjusted. When the liquid level of the water tank 1 drops rapidly, the controller 3 automatically sends instructions to gradually increase the starting number of the water pump 2 and increase the water injection amount to the water tank 1; when the liquid level of the water tank 1 rises rapidly, the controller 3 automatically reduces the starting number of the water pump 2 and reduces the water injection amount. At the same time, the controller 3 will also adjust the output flow of the fire pump according to the change of the water supply flow and pressure to ensure the stability of the water supply.

The above examples are only used to help understand the method of the present application and its core idea; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed. In conclusion, the content of the present application should not be understood as a limitation of the present application.
