[0002] Fire hydrants are a type of fixed firefighting tool. Their main functions are to control combustibles, isolate combustion-supporting materials, and eliminate fire sources. Fire hydrants are mainly used by fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses or water guns to discharge water for firefighting. Therefore, the outdoor fire hydrant system is also one of the important firefighting facilities for fighting fires.

[0025] Working principle:

[0026] The utility model is buried underground, the upper surface of the box body 1 is flush with the ground, the water inlet pipe 4 arranged on one side of the box body 1 is connected to the fire-fighting pipeline; the drainage pipe 5 arranged on one side of the box body 1 is connected to the drainage pipe 5; the water flows into the valve body 81 of the regulating valve 8 from the water inlet hole 82 connected with the valve body 81 of the regulating valve 8 through the water inlet pipe 4, and is transported to the connecting hose 9 from the first water outlet hole 83 arranged on the valve body 81, and the water is transported to the fire hydrant 7 through the connecting hose 9.

[0027] In case of fire, the first door 2 and the second door 3 provided on the box door are opened, and the second hand wheel 87 of the regulating valve 8 under the second door 3 is turned. The second hand wheel 87 drives the valve stem 85 to rotate, so that the valve plate 86 in the regulating valve 8 rises under the drive of the valve stem 85, and the second water outlet 84 provided on the valve body 81 of the regulating valve 8 is opened. Water flows from the second water outlet 84 provided on the valve body 81 to the first water delivery pipe 10, and then is transported from the first delivery pipe to the second water delivery pipe 11. The water flows into the cavity provided in the outer shell 61 of the lifting device 6 through the water through hole 65 connected with the second water delivery pipe 11, and the high pressure After the water flows into the cavity provided in the outer shell 61, it squeezes the piston 62 provided in the cavity, so that the piston 62 drives the telescopic rod 63 to rise, and the telescopic rod 63 drives the fixed plate 64 and the fire hydrant 7 fixedly connected to the fixed plate 64 to rise, so that the fire hydrant 7 extends from the opening of the first box door 2 to the ground. After the fire hydrant 7 is fully extended, the first hand wheel 14 on the regulating valve 8 is turned to make the valve plate 86 block the second water outlet, and the second water outlet is closed. The water flow in the cavity provided in the outer shell 61 of the lifting device 6 cannot be discharged and is in a pressure-maintaining state, thereby fixing the extended fire hydrant 7 to prevent the fire hydrant 7 from retracting.

[0028] After use, the first hand wheel 14 under the second box door 3 is turned to make the first hand wheel 14 drive the connecting rod 13 to rotate, and the drain valve 12 is driven by the connecting rod 13 to open the drain valve 12, and the water stored in the first water pipe 10 and the second water pipe 11 is discharged through the drain pipe 5. At the same time, the fire hydrant 7 squeezes the telescopic rod 63 under the action of its own gravity, so that the telescopic rod 63 squeezes the piston 62, and the water in the cavity provided in the outer shell 61 of the lifting device 6 is squeezed by the piston 62 and discharged from the water hole 65 to the second water pipe 11, and then discharged from the box 1 from the drain pipe 5 connected to the second water pipe, so that the fire hydrant 7 can be retracted downward into the box 1 under the action of its own gravity, so as to achieve the effect of being easy to hide underground, reducing the occupation of the ground and the impact on traffic. At the same time, the box 1 protects the internal components to prevent rust caused by long-term exposure to the outside, thereby causing poor stability of the fire hydrant 7.
