A second water delivery pipe 10 is fixedly connected between the water storage tank 4 and the water supply pump group 6. A second water delivery pipe 11 is fixedly connected between the water supply pump group 6 and the fire reserve water tank 3. The fire reserve water tank 3 is connected to the fire pipe network. A third water supply pipe 12 is fixedly connected between the water tank 4 and the fire-fighting pipe network, a return pipe 13 is fixedly connected between the water tank 4 and the fire-fighting pipe network, a water supply pipe 14 and a drainage pipe 16 are fixedly connected to the water tank 4, a second electrically-controlled butterfly valve 15 is arranged on the water supply pipe 14, a manual butterfly valve 17 is arranged on the first water supply pipe 8, the first water supply pipe 9, the second water supply pipe 10, the return pipe 13 and the drainage pipe 16, and a liquid level sensor is arranged inside the fire-fighting reserve water tank 3 and the water tank 4, the liquid level sensor is electrically connected to the control cabinet 7, and the liquid level sensor cooperates with the control cabinet 7 to control the operation of the first electrically-controlled butterfly valve 1, the water supply pump group 6 and the second electrically-controlled butterfly valve 15; The fire protection pipe network includes an upper transverse pipe 18 and a lower transverse pipe 19. The upper transverse pipe 18 is connected to the third water supply pipe 12. The first water supply pipe 9 and the return pipe 13 are both connected to the lower transverse pipe 19. A plurality of longitudinal pipes 20 are fixedly connected between the upper transverse pipe 18 and the lower transverse pipe 19. A plurality of floor fire hydrants 21 are arranged on the longitudinal pipes 20. The plurality of floor fire hydrants 21 correspond to each floor of the building respectively. A test fire hydrant 22 is arranged on the upper transverse pipe 18. The fire reserve water tank 3 and the test fire hydrant 22 are both located on the roof. Firefighters can connect the fire truck water supply pipeline with the full-pass valve 2, and operate the control cabinet 7 to remotely close the first electric-controlled butterfly valve 1, and use the longitudinal pipe 20 where the first electric-controlled butterfly valve 1 and the full-pass valve 2 are located to replace the firefighters in laying water hoses in a winding manner in the stairwell or laying water hoses vertically to supply fire-fighting water to the floors, thereby reducing the laying time and avoiding greater losses caused by fire.

[0019] Working principle of the present invention: When the wet fire hydrant system is in normal use, the city water supply pipeline is connected to the water supply pipe 14. The liquid level sensor provided in the water storage tank 4 cooperates with the control cabinet 7 to ensure that the water level in the water storage tank 4 is within a certain range by regulating the opening of the second electrically controlled butterfly valve 15, thereby ensuring fire water supply. The fire booster and pressure stabilizing device 5 can supply water to the fire pipe network and ensure a certain water pressure. When the floor is high, the fire reserve water tank 3 can assist the fire booster and pressure stabilizing device 5 to supply water to the fire pipe network, thereby ensuring that the water pressure in the fire pipe network can also meet the high-rise fire fighting needs. The liquid level sensor provided in the fire reserve water tank 3 cooperates with the control cabinet 7 to ensure that the water level in the fire reserve water tank 3 is within a certain range by regulating the opening of the water supply pump group 6, thereby ensuring the effective water supply from the fire reserve water tank 3 to the fire pipe network. When the wet fire hydrant system is deactivated and water is cut off, if a fire occurs on a floor, the control cabinet 7 can be used to remotely close the first electrically controlled butterfly valve 1, and the firefighters connect the fire truck water supply pipe with the full-pass valve 2, and turn the valve stem 203 through the knob 204, so that the valve stem 203 drives the opening and closing member 205 to rotate inside the valve body 201, thereby changing the water flow direction of the full-pass valve 2, so that the fire truck can supply water to the longitudinal pipe 20 where the first electrically controlled butterfly valve 1 and the full-pass valve 2 are located. The firefighters at the fire point can use the floor fire hydrant 21 on the longitudinal pipe 20 to extinguish the fire on the corresponding floor, reducing the time for laying water pipes and thus avoiding greater losses caused by the fire, thereby buying precious time for fire fighting and rescue work.
