[0037] Fire hydrant pump, set up on the water collecting pipe, when the water flow of the water collecting pipe exceeds the preset value, the pump starts to work.

[0038] In one embodiment, the fire water tank includes a water tank body and a leg (not shown in the figure), the leg is fixedly installed at the bottom end of the four corners of the water tank body, the upper end of one side of the water tank body is provided with a water inlet, the water inlet is connected with an external water source system through a water inlet pipeline, the external water source system can be an external water pipe, a one-way valve and a first electric valve are arranged on the water inlet pipeline, an automatic exhaust valve is also arranged on the water inlet pipeline, a drain pipe is installed at the bottom of the fire water tank, and a valve is installed on the drain pipe.

[0039] The water tank body is provided with a liquid level meter, the liquid level meter is fixedly installed on a mounting seat in the water tank body, and the liquid level meter is electrically connected with the first electric valve through the controller. The liquid level in the water tank body is monitored through the liquid level meter. When the water in the water tank body is lower than the first liquid level (low level) set by the liquid level meter, the liquid level meter outputs a signal. After the controller receives the signal, the first electric valve is controlled to start. The water pipe delivers water into the water tank body. When the liquid level reaches the second liquid level (high level), the liquid level meter stops outputting the signal, and the controller controls the first electric valve to stop working, so that automatic water supply treatment of the fire-fighting water in the fire-fighting water tank is realized, and the phenomenon of water shortage in the fire-fighting water tank is avoided.

[0040] In one embodiment, the diameter of the collecting pipe is greater than the diameter of the water outlet pipe. For example, the diameter of the water outlet pipe is DN50, and the diameter of the collecting pipe is DN100. For another example, the diameter of the water outlet pipe is DN80, and the diameter of the collecting pipe is DN100. The collecting pipe reduces the arrangement of the pipeline, and multiple pressure gauges do not need to be arranged on the pipeline. Whether the hydrant pump needs to be started to maintain the water pressure of the hydrant pipe network can be determined according to the water flow of the collecting pipe.

The external water source system delivers the external water source into the fire-fighting water tank. However, because the water source of the fire-fighting water tank cannot be rapidly replenished, the second electric valve is turned on so that the water in the water storage tank can be used as a compensation point to ensure that the water source is sufficient and can be used in time. When it is detected that the water level in the fire-fighting water tank is located at the second liquid level, the controller controls the first electric valve and the second electric valve to be closed according to the signal of the liquid level meter.
