[0021] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] like Figure 1-Figure 4 As shown, an intelligent ground fire hydrant comprises a fire hydrant body 1, wherein the fire hydrant body 1 is provided with a water inlet and a plurality of water outlets, wherein a valve stem 5 is provided in the fire hydrant body 1 and the valve stem 5 passes through the fire hydrant body 1, wherein a valve flap 6 is provided on the valve stem 5, wherein a valve seat 4 is provided in the fire hydrant body 1, wherein the valve flap 6 is sealed on the valve seat 4, wherein the valve stem 5 comprises a first valve stem 51 and a second valve stem 52, wherein the first valve stem 51 is provided on the fire hydrant body 1, wherein the second valve stem 52 is fixedly connected with the valve flap 6, wherein the first valve stem 51 and the second valve stem 52 are linked, wherein the first valve stem 51 and the second valve stem 52 have an anti-leakage separation device for separating the first valve stem 51 and the second valve stem 52 and making the valve flap 6 still sealed on the valve seat 4 to prevent leakage of fire water after the fire hydrant body 1 is damaged by a predetermined external force impact.

[0023] Specifically, the anti-leakage separation device includes a first tooth row 7 and a second tooth row 8, a first channel is opened on the second valve stem 52, a first sliding channel connected to the outside is opened horizontally on the inner wall of the first channel, and a second sliding channel connected to the first valve stem 51 is opened longitudinally on the inner wall of the first channel, the first tooth row 7 is slidably arranged in the first sliding channel, the fire hydrant body 1 is located at the first sliding channel and is matched with a limiting channel 10 for the first tooth row 7 to be inserted, the second tooth row 8 is slidably arranged in the second sliding channel, and the second valve stem 52 is located in the first channel and is provided with a limit channel 10 for hitting the fire hydrant Then, the gear 9 drives the first tooth row 7 to slide horizontally and the second tooth row 8 to slide longitudinally. The gear 9 is rotatably arranged in the first channel. The gear 9 is respectively meshed with the first tooth row 7 and the second tooth row 8 for transmission. A driving motor (not shown in the figure) for driving the gear 9 to rotate is arranged in the first channel. A pressure sensor (not shown in the figure) for sensing external impact pressure and driving the driving motor to work is arranged on the fire hydrant body 1. A controller (not shown in the figure) is arranged on the fire hydrant body 1. The controller is electrically connected to the pressure sensor and the driving motor.

[0024] Specifically, a first magnetic block is provided in the second tooth row 8 and the first magnetic block is located at the upper end of the second tooth row, and the first valve stem 51 is located at the second sliding channel and is provided with a second magnetic block magnetically attracted to the first magnetic block. When the second tooth row 8 penetrates into the second sliding channel to realize the linkage with the first valve stem 51 and the second valve stem 52, the first magnetic block and the second magnetic block are magnetically attracted to each other, so that the first valve stem 51 drives the second valve stem 52 to rise, and then drives the valve flap 6 to rise, thereby opening the fire hydrant.

[0025] In order to further prevent water leakage and avoid waste of water resources, a sealing ring block 12 is provided between the valve seat 4 and the valve disc 6, which further seals the valve disc 6 on the valve seat 4 after the first valve stem 51 and the second valve stem 52 are disengaged. A second channel is opened around the valve seat 4, and the sealing ring block 12 is slidably arranged in the second channel. The sealing ring block 12 resists the sealing disc, and a spring 13 is provided between the sealing ring block 12 and the second channel. A plurality of solenoid coils 14 capable of generating a magnetic field are provided between the sealing ring block 12 and the valve seat 4, which are used to actively push the sealing ring block 12 to tightly resist the valve disc 6 after the fire hydrant is hit. The sealing ring block 12 has the same magnetic property as the solenoid coil 14, and a control button 11 for turning on the power to the solenoid coil 14 is provided in the limiting channel 10. The first tooth row 7 slides into the first sliding channel to resist the control button 11.

[0026] In order to further protect the fire hydrant and improve the service life and impact resistance of the fire hydrant, it also includes a plurality of anti-collision plates 2 that can surround the fire hydrant body 1, and the anti-collision plate 2 is fixedly connected with a sliding rod 3, and the fire hydrant body 1 is threaded with a sleeve rod 31. The sliding rod 3 is slidably inserted into the sleeve rod 31, and a shock-absorbing spring 32 is provided between the sliding rod 3 and the sleeve rod 31.

[0028] Working principle:

[0029] When the fire hydrant is hit, the predetermined external force hits the anti-collision plate 2 and reaches the point where it can destroy the fire hydrant, the pressure sensor transmits a signal to the controller, the controller controls the driving motor to rotate, the driving motor drives the gear 9 to rotate, at this time the gear 9 drives the first tooth row 7 and the second tooth row 8 to slide, the first tooth row 7 slides out of the first sliding channel and penetrates the limiting channel 10, at the same time the second tooth row 8 slides downward in the second channel, so that the second tooth row 8 is separated from the first valve stem 51, the external force hits the upper part of the fire hydrant and damages the valve stem 5, because the second valve stem 52 is limited by the limiting channel 10, the valve disc 6 always seals the valve seat 4. When the first tooth row 7 slides into the limiting channel 10, it resists the control button 11, at this time the solenoid 14 is energized to generate magnetism, and the magnetic repulsion with the sealing ring block 12 pushes the sealing ring block 12 to resist tightly on the valve disc 6. When the controller controls the driving motor, it also transmits the signal to the wireless transmission module, and the wireless transmission module transmits the signal to the external central control terminal, so that the staff can handle the fire hydrant in time.
