[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 In an embodiment of the utility model, a fire hydrant leakage detection device includes a sealing cylinder and further includes:

[0025] A detection mechanism, the detection mechanism comprising a round box, a fixing plate, a transmission rod, a force-bearing rod, a connecting rod, an extrusion plate, a guide rod, a force-bearing spring and a pressure sensor;

[0026] Among them, a support rod is arranged between the round box and the outer side of the sealing cylinder to fix the two together, a transmission rod coaxially arranged therewith is opened on the top of the round box, the fixed plate is fixed at the inner edge of the round box, the pressure sensor is fixed at the inner edge of the round box, one end of the guide rod is fixed on the fixed plate, one end of the extrusion plate is fixed on the transmission rod, and the other end of the extrusion plate is slidably sleeved on the guide rod, the force spring is sleeved on the guide rod and the two ends of the force spring are respectively in contact with the extrusion plate and the pressure sensor, one end of the connecting rod forms a rotational fit with the force rod, and the other end of the force rod is fixed to the transmission rod;

[0027] In the utility model, one end of the connecting rod is fixed on the valve stem of the fire hydrant water valve. If the valve stem rotates, the valve stem pulls the force rod through the connecting rod, the force rod drives the transmission rod to rotate, the extrusion plate on the transmission rod squeezes the force spring, and the pressure signal of the pressure sensor increases, thereby determining that the fire hydrant is not closed normally.

[0028] Specifically, one end of the sealing cylinder is provided with an annular groove coaxially arranged therewith, and the outer side of the annular groove is provided with a plurality of threaded holes equidistantly distributed in an annular pattern around its central axis, and locking bolts are threadedly installed in the threaded holes. The sealing cylinder is sleeved on the drainage end of the fire hydrant water valve, and the locking bolts are tightened to complete the fixation.

[0029] Specifically, a sealing ring for improving sealing performance is sleeved and fixed on the inner side wall of the annular groove.

[0030] Specifically, a water level sensor is installed on the outside of the sealing cylinder, and the detection end of the water level sensor is arranged inside the sealing cylinder. The water level sensor is a prior art, and its specific structure and working principle are not described in detail here.

[0031] Specifically, a control box is installed on the outside of the sealing cylinder, a controller is installed inside the control box, and the pressure sensor is electrically connected to the controller. The controller is a prior art, and its specific structure and working principle are not described in detail here.

[0032] Specifically, a battery is installed inside the control box, the battery is electrically connected to the controller, and the battery is used to provide power.

[0033] Specifically, a signal transmitter is installed inside the control box, and the signal transmitter is electrically connected to the controller. The signal transmitter is used to transmit signals. The signal transmitter is a prior art, and its specific structure and working principle are not described in detail here.

[0034] Working principle: The sealing cylinder is set on the drainage end of the fire hydrant water valve. When leakage occurs, water accumulates in the sealing cylinder. The water level sensor detects and determines the leakage. If the detection mechanism works, its specific work is: one end of the connecting rod is fixed on the valve stem of the fire hydrant water valve. If the valve stem rotates, the valve stem pulls the force rod through the connecting rod, and the force rod drives the transmission rod to rotate. The extrusion plate on the transmission rod squeezes the force spring, and the pressure signal of the pressure sensor increases, thereby determining that the fire hydrant is not closed normally. If the detection mechanism does not work, it is determined that the seal of the fire hydrant water valve has failed.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
