[0055] The wireless transmitting module is connected to the piezoelectric sheet.

[0056] The specific working process of the present invention is:

[0057] The principle of anti-theft water in this scheme is to use the arc column 1 to limit the position of the switch valve 2, that is, a notch 21 is set on the outside of the switch valve 2, and the arc opening of the arc column 1 is set downward, so that the inner side of the arc column 1 can be stuck on the notch 21, and the switch valve 2 will no longer rotate;

[0058] The arc column 1 exerts pressure on the lifting plate 10 under the action of the fastening structure, and the lifting plate 10 drives the arc column 1 to descend, and the arc column 1 is clamped on the notch 21 on the switch valve 2. Only when the lifting plate 10 can rise, the arc column 1 can be separated from the switch valve 2.

[0059] A fixed cover 4 and a rotating cover 3 are provided to adjust the engagement position of the arc column 1 and the notch 21, so as to prevent the arc column 1 from being unable to engage with the notch 21 due to misalignment;

[0060] The arc column 1 in this solution also has the effect of a handle or a lifting handle, that is, when people transport the fire hydrant, they can hold the arc column 1 and lift or drag the entire fire hydrant, which is convenient and quick;

[0061] See also Fig.10 , a fastening structure is provided. Under the action of the motor 86, the driving gear 83 drives the driven gear 82, and the driven gear 82 drives the stud 8 to rotate, and the stud 8 can be lifted and lowered, thereby adjusting the height of the lifting plate 10. The motor 86 is connected to the wireless receiving module. People hold the wireless transmitting module. Only through the signal of the wireless transmitting module can the motor 86 be started, so that the water theft phenomenon of the fire hydrant is avoided to the greatest extent;

[0062] The motor 86 in this solution is a forward and reverse motor 86, which can rotate forward and reverse, so as to facilitate the adjustment of the lifting height of the stud 8. The wireless transmitting module does not directly control the forward and reverse rotation of the motor 86. In fact, it is a communication tool. As a signal transmission tool, the wireless transmitting module sends a signal, which is transmitted to the motor controller through the wireless receiving module. The motor controller controls the forward and reverse rotation of the motor 86. Specifically, the wireless transmitting module encodes the control information in a certain way and modulates the infrared or ultrasonic or wireless signal, and transmits it. The wireless receiving module receives the signal and decodes the corresponding control information through amplification, demodulation and decoding, and then sends it to the control circuit to perform relevant control. The control process and the specific wiring method are all existing technologies and will not be described in detail here.

[0063] Finally, a universal wheel is provided, and the universal wheel is connected to the pressure plate 81 through a connecting rod mechanism. When the fire hydrant needs to be transferred, the stud 8 rises, and the rotating rod 9 is driven to rotate through the sliding column 111. The rotating rod 9 drives the rotating shaft to rotate, and the rotating shaft drives the universal wheel to rotate toward the ground until it reaches a suitable angle. At this time, the universal wheel contacts the ground. When the arc column 1 is pulled, the universal wheel is supported on the ground, which greatly facilitates the transfer of the fire hydrant.

[0064] When the transfer is completed, under the action of the motor 86, the stud 8 descends, and the arc column 1 is stuck in the notch 21 of the switch valve 2. At the same time, under the action of the pressure plate 81 and the bending rod 11, the rotating rod 9 and the universal wheel rotate, and the universal wheel is retracted from the ground, which facilitates the installation of the fire hydrant and greatly increases the multifunctional technical effect of the fire hydrant.

[0065] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
