S2: and (3) antifreezing of the fire hydrant:

under normal conditions, the depth of a water source in the bolt body can rise to the upper edge part of the bolt body, namely the liquid level in the bolt body can be positioned near the self-adaptive interface, when cold weather is met, if the part of the water source between the ground and the liquid level is not discharged, the part of the water source is easier to freeze compared with the water below the ground, and after freezing, certain pressure can be caused on the inner wall of the bolt body to freeze and crack the part of the water source, therefore, the temperature sensor is designed to detect the weather temperature in real time, when the temperature of the day is detected to be lower, a signal is sent to the controller, so that the waterproof motor is started through the controller, the first connecting rod is driven to rotate through the output end of the waterproof motor, the fan-shaped baffle plate is rotatably connected with the baffle plate through the rotating shaft, the second connecting rod is fixedly connected with one end, close to the rotating shaft, the reciprocating groove is designed on the second connecting rod, and the inserting rod is inserted in the reciprocating groove, the inserted bar is fixedly connected with one end of the top of the first connecting rod away from the waterproof motor, so that the fan-shaped baffle is driven to rotate, the fan-shaped notch of the fan-shaped baffle is blocked, and water above the ground is completely separated from the water below the ground.

The electromagnetic valve is started through the controller, so that the drain pipe is opened, water above the ground in the bolt body is discharged from the bolt body, one end, far away from the bolt body, of the drain pipe is connected with a city drainage system, and the water above the ground can be directly collected into the drainage system after being discharged.

S3: anti-theft of the fire hydrant:

the standard distance value between the inner part of the controller and the outer wall of the bolt body when the blank cap is screwed down is preset, when a person opens the blank cap by private use or the blank cap is impacted and equal to the displacement on the self-adaptive interface, the position sensor detects that the distance between the position sensor and the metal induction column is changed, so that the signal is sent to the controller, the controller starts the audible and visual alarm to emit light and sound, and the warning effect is achieved.

The invention has the beneficial effects that:

1. by designing an adjusting mechanism, namely two elastic clamping assemblies and two limiting assemblies, when fire-fighting water pipes with different pipe diameters are butted with a self-adaptive interface, firstly, two inner buckles are buckled into the interior of the fire-fighting water pipe, then a pressing disc is manually adjusted to drive a sliding rod and the interior of a fixed block to slide up and down, the arc-shaped clamping plate is fixedly connected with the sliding rod so as to drive the arc-shaped clamping plate to slide in a slot, when the arc-shaped clamping plate slides to meet the current requirement of butting of the fire-fighting water pipe, two conical buckles are clamped with two conical notches on the sliding rod so as to lock the sliding rod, the sliding of the arc-shaped clamping plate is stopped, the outer edge of the fire-fighting water pipe is limited, the inner buckle and the outer buckle are matched to completely lock the inside and the outside of the fire-fighting water pipe, the fixed connection of the fire-fighting water pipe and the self-adaptive interface is ensured, and two reset springs drive the two conical buckles to stretch by utilizing self elasticity, the realization is to the locking and the unblock of slide bar to satisfy the sliding adjustment of slide bar, make fire hose and self-adaptation interface peg graft conveniently, labour saving and time saving simultaneously not only can make the fire hose that is derived from adaptation interface and different pipe diameters successfully dock, simultaneously through two elastic design's arc cardboard, has accelerateed the butt joint process, and then is favorable to promoting fire fighting efficiency.

2. According to the invention, through designing the warning component, namely the metal sensing column, the position sensor and the audible and visual alarm, a standard distance value between the controller and the outer wall of the bolt body when the blank cap is screwed down is preset in the controller, when a person opens the blank cap by himself or the blank cap is impacted and is equal to the displacement on the self-adaptive interface, the position sensor detects that the distance between the position sensor and the metal sensing column is changed, so that the signal is sent to the controller, the audible and visual alarm is started by the controller to emit light and sound, and the warning effect is achieved.

3. The invention designs the temperature sensor, the drain pipe and the electromagnetic valve, and designs the rotating component, namely the waterproof motor, the first connecting rod, the second connecting rod and the fan-shaped baffle plate, under normal conditions, the depth of a water source in the bolt body can rise to the upper edge part of the bolt body, namely the liquid level in the bolt body can be positioned near the self-adaptive interface, when the temperature sensor is in cold weather, if the part of the water source between the ground and the liquid level is not discharged, the water below the ground is easier to freeze, and after the water is frozen, certain pressure can be caused on the inner wall of the bolt body to frost crack the inner wall of the bolt body, so the temperature sensor is designed to detect the weather temperature in real time, when the temperature in the day is detected to be lower, the signal is sent to the controller, so the waterproof motor is started through the controller, the first connecting rod is driven to rotate through the output end of the controller, and the fan-shaped baffle plate is rotatably connected with the clapboard through the rotating shaft, the one end fixed connection that second connecting rod and fan-shaped baffle are close to the rotation axis, the design has reciprocal groove on the second connecting rod, the inserted bar is pegged graft with reciprocal groove, the inserted bar is kept away from the top one end fixed connection of waterproof motor with first connecting rod again, thereby it is rotatory to drive fan-shaped baffle, and then make fan-shaped baffle advance fan-shaped breach and plug up, guarantee that the water above ground is separated completely with subaerial, then, start the solenoid valve through the controller, thereby make the drain pipe open, the water that will tie the internal portion of body to be located above ground is discharged from the bolt internal, the one end that the bolt was kept away from to the drain pipe links to each other with urban drainage system, can directly converge drainage system after the water discharge that is located above ground, avoid directly arranging the ponding that subaerial caused with water, can not influence traffic and pedestrian.

4.
