Outdoor fire hydrants are water supply facilities installed on the fire-fighting water supply network outside the building. They are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire-fighting water supply network to implement fire extinguishing. They can also be directly connected to water hoses and water guns to discharge water for fire extinguishing. Outdoor fire hydrants are also one of the important fire-fighting facilities for fighting fires.

[0022] like Figures 1 to 4As shown, the fire hydrant leakage detection device of this embodiment includes a fire hydrant body 1, and a plurality of fire outlets 2 are arranged on the surface of the fire hydrant body 1. The number of the fire outlets 2 is multiple, and the fire outlets 2 are used to discharge fire water. An L-shaped plate 3 is detachably installed on the surface of the fire hydrant body 1 below the fire outlet 2, and a water collecting ring 1 4 is installed on the upper end of the L-shaped plate 3. A water collecting ring 2 5 is detachably installed on one end of the water collecting ring 1 4. A water collecting ring 2 5 is detachably installed on the upper end of the water collecting ring 1 4 and the water collecting ring 2 5. A water collecting trough 6 is arranged together at the upper ends of the water collecting ring 1 4 and the water collecting ring 2 5. The water collecting trough 6 formed by the combination of the water collecting ring 1 4 and the water collecting ring 2 5 can collect water leaking from the fire hydrant body 1, and a water outlet is installed at the lower end of the water collecting ring 1 4. Pipe 7, a water box 8 is movably installed between the lower part of the water outlet pipe 7 and the L-shaped plate 3, a push switch 9 is installed at the upper end of the L-shaped plate 3 below the water box 8, and an alarm 10 is installed below the L-shaped plate 3. The water inside the water collecting tank 6 composed of the water collecting ring 1 4 and the water collecting ring 2 5 flows from the water outlet pipe 7 to the inside of the water box 8. As the water inside the water box 8 increases, the water box 8 descends to press the push switch 9. The push switch 9 controls the alarm 10 to sound an alarm, which is convenient for issuing a reminder when a leak occurs in the fire hydrant body 1. A false trigger component is installed on one side of the push switch 9. The false trigger component is used to prevent the alarm 10 from being triggered by mistake on rainy days.
[0023] Specifically, connecting rings 12 are installed at both ends of the L-shaped plate 3 . The two connecting rings 12 are installed on the surface of the fire hydrant body 1 by bolts, and the L-shaped plate 3 is installed through the connecting rings 12 .
[0024] Furthermore, the water collecting ring 1 4 and the water collecting ring 2 5 are both semicircular, and the front and rear parts of the lower end of the water collecting ring 1 4 are symmetrically installed with a clamping block 13, and the front and rear parts of the lower end of the water collecting ring 2 5 are symmetrically installed with a fixing plate 14. One end of the fixing plate 14 is provided with a slot, and the clamping block 13 is respectively located inside the slot. The clamping block 13 on the water collecting ring 1 4 is inserted into the inside of the slot on the water collecting ring 2 5, so as to realize the combined installation of the water collecting ring 1 4 and the water collecting ring 2 5.
[0025] Furthermore, guide rods 15 are installed on both sides of the lower end of the water box 8. The lower ends of the guide rods 15 pass through the L-shaped plate 3 through the through holes. Elastic springs 16 are installed on the surfaces of the guide rods 15 between the bottom end of the water box 8 and the L-shaped plate 3. The water box 8 can move up and down. The guide rods 15 guide the movement of the water box 8. The elastic springs 16 are used to support the water box 8. When the water inside the water box 8 reaches a certain capacity, the water box 8 can compress the elastic springs 16 to realize the pressing of the press switch 9 by the water box 8.
[0026] Furthermore, the false trigger component includes a raindrop sensor 1101 and an electric push rod 1102. The raindrop sensor 1101 is installed on one side of the surface of the water collecting ring 4 through a mounting plate, and the electric push rod 1102 is installed on the upper end of the L-shaped plate 3 on one side of the push switch 9. The raindrop sensor 1101 is used to sense whether it is raining. The model of the raindrop sensor 1101 is TEJIATE. The working principle of the raindrop sensor 1101 is a known prior art means, so no further description is made. When raindrops are detected on the raindrop sensor 1101, the controller controls the electric push rod 1102 to extend to support the water box 8 to prevent the water box 8 from descending and causing false triggering of the push switch 9. The device is only used to detect slight water leakage in the fire hydrant body 1 and is not suitable for large-scale spraying of fire water from the fire hydrant body 1.
[0027] Furthermore, a control box 17 is installed at the lower end of the L-shaped plate 3, and a power supply and a controller are installed inside the control box 17. The power supply is used to power various electrical components. The alarm 10 is installed on the surface of the control box 17. A drain pipe 18 is installed at one end of the water box 8. An electric valve 19 is installed on the drain pipe 18. The drain pipe 18 is used to drain the water inside the water box 8, and the electric valve 19 is used to control the on-off of the drain pipe 18.
[0028] The method of using this embodiment is as follows: when in use, the L-shaped plate 3 is installed on the surface of the fire hydrant body 1 through the connecting ring 12, and the water collecting ring 1 4 and the water collecting ring 2 5 are installed on the surface of the fire hydrant body 1. When the fire hydrant body 1 leaks, the water leaking from the fire hydrant body 1 flows into the water collecting trough 6 formed by the water collecting ring 1 4 and the water collecting ring 2 5. The water collected in the water collecting trough 6 is discharged into the water box 8 through the outlet pipe 7. As the water in the water box 8 increases, the gravity of the water box 8 increases, and the water box 8 drives the guide rod 15 to move downward. At the same time, the water in the water box 8 is discharged into the water box 8. The water box 8 compresses the elastic spring 16, and the water box 8 descends to press the push switch 9. The push switch 9 controls the alarm 10 to sound an alarm, which serves as a prompt for the leakage of the fire hydrant body 1. When it rains, when raindrops are detected on the raindrop sensor 1101, the controller controls the electric push rod 1102 to extend to support the water box 8, so as to prevent the water box 8 from accidentally triggering the push switch 9. After the rain stops, the electric valve 19 controls the drain pipe 18 to open, so as to realize the automatic discharge of water inside the water box 8.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
