The push switch 8 is located on the movement path of the tool when the fire hydrant valve 11 is opened, such as the top of the fire hydrant valve 11, in order to prevent the fire hydrant valve 11 from opening normally. The wireless transmission module is used to transmit the on-off state of the push switch 8 to the monitoring terminal. The push switch 8 includes a fixed end and a pressing end that is kept in an energized state by applying pressure and has a self-recovery ability. The pressing end of the push switch 8 abuts against the fire hydrant valve 11 in an energized state. The fixed end of the push switch 8 is detachably connected to the fire hydrant through a connecting piece. The connecting piece can be a lead seal 13, a cable tie, a rope, etc. A plurality of connecting holes can be opened at the fixed end of the push switch 8. The position of the connecting hole is higher than the hole of the annular protective member 12 around the valve 11. The lead seal 13, the cable tie, the rope, etc. are used to pass through the valve in sequence. The holes and connecting holes of the annular protective member 12 around the door 11 are fixed. When disassembling, the lead seal 13, cable tie and rope can be directly cut. The wireless transmission module is electrically connected to the push switch 8, and the connecting member is used to keep the pressing end of the push switch 8 against the valve 11 of the fire hydrant. The push switch 8 is in the on state. When water is taken illegally, the connecting member needs to be removed and the push switch 8 is removed. At this time, the push switch 8 loses its holding force and bounces open in the disconnected state. The wireless transmission module transmits the information that the push switch 8 is disconnected to the monitoring terminal. The staff can know that the fire hydrant has been illegally operated. By calling the monitoring of the relevant position, the illegal operator can be checked to realize the monitoring of the fire hydrant. By abutting the push switch 8 against a stable valve body, compared with measuring the water pressure, the false alarm can be effectively reduced, and the monitoring effect is improved. At the same time, the push switch 8 is low in cost, which reduces the investment cost.

[0032] The wireless transmission module includes a main board 6, a flow card 5 and a transmission antenna 4. The push switch 8, the flow card 5 and the transmission antenna 4 are all electrically connected to the main board 6.
