[0020] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0021] 1. A dynamic identification mechanism is provided. Through the coordination of the electromagnetic shielding room, sliding plate, winding drum, mounting seat, source coil, branch coil, support frame, iron core and permanent magnet, a comparative identification structure can be constructed to transform and utilize the electromagnetic force in the process of electric energy transmission, and synchronously transform the electromagnetic disturbance force. With the detection function of the sliding rod, pressure isolation groove and signal switch, the power transmission amount on the supply side and the user side can be monitored in real time and dynamically. It not only effectively improves the timeliness, effectiveness and identification accuracy of the detection work, but also makes the detection work more stable, efficient and continuous. Through the real-time comparison between the supply side and the user side, multi-point comprehensive joint control monitoring is also indirectly realized. While improving the detection accuracy, the power consumption of each user is transformed into a disturbance factor, which realizes mutual supervision among users in disguise, makes each user mutually restrained, greatly enhances the difficulty of cracking the device, and increases the difficulty of users stealing electricity;

[0022] By installing the ring seat, the inner support tube, the mutual inductance coil and the conductor in coordination, the electromagnetic disturbance in the process of electric energy transmission can be transformed and utilized, and the invalid electromagnetic disturbance can be turned into the driving force of the device, which not only effectively reduces the energy consumption of the device, makes the device more energy-saving and emission-reducing, and greatly improves the convenience of use of the device, but also makes the working process of the device more compatible with the power supply work, and at the same time improves the endurance effect of the device. By adjusting the chamber, the piston plate, the threaded rod and the slot in coordination, the electromagnetic repulsion in the working process of the device can be compensated, and the equivalent compensation of the line loss can be achieved, which greatly improves the working accuracy of the device, improves the compatibility and adaptability of the device with the working environment, and makes the device more efficient and stable. At the same time, it can limit the action sensitivity of the device to avoid misjudgment of the device and further improve the reliability of the device. By cooperating with the protective tube and the sealing sleeve, the sealing of the device can be greatly improved, making the working process of the device more stable.

[0023] 2. An explosion-proof monitoring mechanism is provided.

At the same time, it can shorten the repair time of the staff and ensure the safety of power supply work;

[0024] Through the coordination of the guide box, side grooves, movable grooves, side holes, strips, push rods and screw rods, a dual monitoring structure can be constructed, which can detect the status of the external meter box to prevent the box door from being violently opened, and is equipped with an anti-violent demolition structure to form internal and external dual protection detection. While improving the stability of the detection work, it effectively avoids misjudgment of the device and makes the detection result more reliable. Through the coordination of the connecting port, telescopic tube and connecting tube, the stability of the pressure transmission medium is effectively improved, and the response of the device is more stable. Through the coordination of the threaded ring and the threaded seat, the convenience of the correction and adjustment work of the device is greatly improved. Through the coordination of the air pipe, solenoid valve and valve, the adjustable range of the device can be effectively improved, and the adaptability of the device to the external environment can be improved, so that the device can be applied to meter boxes of different specifications, and the effective adaptability of the device is improved.

[0062] Working principle and use process of the present invention: When the present AR and knowledge graph-based electricity safety and anti-electricity theft identification device is actually used, first push the push rod 319 to make the threaded ring 321 abut against the threaded seat 322, and rotate the threaded ring 321 to screw it into the threaded seat 322, limit the push rod 319, so that the strip 318 cannot slide inside the movable groove 316, and perform preliminary position correction on the device so as to make subsequent adaptive adjustments to it;

[0063] Then, according to the actual situation, the detection box 100 is placed at an appropriate position in the meter box, so that the cable on the power supply side passes through the inner side of the airbag ring 305 on the inner support tube 212 on one side of the winding drum 203, and the cables corresponding to each user on the user side pass through the inner side of the airbag ring 305 on the inner support tube 212 on one side of the mounting seat 204 in turn, and then the solenoid valve 324 is opened, and the external inflation device is used to inject clean air into the movable groove 316 through the valve 325 on one side of the air pipe 323. Under the guidance of the air pipe 323, the clean air will enter the flow groove 301 through the solenoid valve 324, and simultaneously enter the sliding groove 302, and then the clean air will enter the sealing shell 101 through the side hole 303, and enter the annular groove 306 under the guidance of the protective tube 210, and finally enter the airbag ring 305 through the guide port 307;

[0064] With the continuous input of airflow, the air pressure inside the airbag ring 305 continues to rise. The airbag ring 305 will expand and deform under the action of the air pressure to squeeze the cable inside it, closely fit with it, limit the inner support tube 212, and ensure the working stability of the mutual inductance coil 213. At the same time, the air pressure on the top of the circular plug 308 will also rise synchronously. When the air pressure is sufficient to overcome the elastic force of the compression spring 310, the circular plug 308 will drop under the action of the top air pressure and press the compression spring 310 at the bottom. At this time, the compression spring 310 will deform and shrink under the pressure.

[0065] At this time, according to the indication of the signal light 102, as the circular plug 308 descends, when the guide rod 309 touches the induction switch 311, the middle signal light 102 will go out, and the solenoid valve 324 will be closed. At this time, the position of the guide rod 309 is the initial position under normal working conditions, and the induction switch 311 is in a state of being pressed by the guide rod 309. After closing the solenoid valve 324, clean air is continuously injected into the movable groove 316 through the valve 325, so that the air pressure on the strip plate 318 is greater than the air pressure on the top of the circular plug 308. The greater the air pressure difference, the more sensitive the reaction of the device during the monitoring process. The pressure difference can be appropriately increased within a safe range according to actual needs;

[0066] Then adjust the position of the detection box 100 again, fix the detection box 100 to the external meter box, rotate the screw rod 320 to make it move relative to the push rod 319, and limit the position of the screw rod 320 so that when the external meter box door is closed, the end of the screw rod 320 can just abut against the external meter box door, and then inject hydraulic liquid into the movable groove 316 through the valve 325 on one side of the threaded seat 322. The hydraulic liquid will enter the side groove 315 synchronously through the side hole 317, and then enter the telescopic tube 312 under the guidance of the connecting pipe 313 and flow out from the connecting port 326 to fill the bottom space of the circular plug 308. The hydraulic liquid here can also be replaced with clean gas, but it should be ensured that the air pressure of the clean gas is equal to the air pressure on the top of the circular plug 308;

[0067] Then, helium is injected into the valve 325 through the valve 325 on the regulating chamber 218, and the helium will enter the electromagnetic shielding chamber 201 synchronously through the slot 221, and the air pressure on the end face of the sliding plate 202 is preliminarily adjusted. The air pressure is a buffer air pressure, that is, during the operation of the device, the sliding plate 202 will only move under the action of the magnetic repulsive force difference when the repulsive force difference on the two end faces of the permanent magnet 209 is greater than the air flow pressure, and the threaded rod 220 is rotated to drive the piston plate 219 to move toward the side of the mounting seat 204, and the helium in the regulating chamber 218 is pressed into the electromagnetic shielding chamber 201 through the slot 221 on one side of the mounting seat 204, and the helium in the electromagnetic shielding chamber 201 is correspondingly drawn into the regulating chamber 218 through the slot 221 on one side of the winding drum 203, and the air pressure on both sides of the sliding plate 202 is finely adjusted, and the line loss in the current transmission process can be compensated to ensure the working accuracy of the device;

[0068] In the aforementioned process, the step of injecting helium into the valve 325 through the valve 325 on the regulating chamber 218 can be uniformly performed when the device leaves the factory. During the on-site installation process, it is only necessary to fine-tune the air pressure on both sides of the sliding plate 202 through the threaded rod 220 according to the actual situation. During this process, the user-side circuit can be connected, and the air pressure on both sides of the piston plate 219 and the sliding plate 202 can be fine-tuned according to the actual current transmission situation, or it can be fine-tuned according to the existing data. According to the indication of the signal light 102, when the signal lights 102 on both sides are off, the adjustment demand is met. At this time, the two ends of the sliding rod 215 are just in contact with the signal switch 217, but the signal switches 217 on both sides are not pressed;

[0069] After completing the above adjustment work, rotate the thread ring 321 to disengage the thread seat 322, release the limit of the strip 318, and then close the external meter box door. Under the limit of the external meter box door, the strip 318 will still remain in the standard position during the adjustment process. Finally, the signal switch 217 and the induction switch 311 are started by the external control terminal to perform the anti-electricity theft identification and detection work;

[0070] During the normal operation of the device, as the user uses electric energy, the current will flow through the cables on the power supply side and the cables on the user side, and the mutual inductance coil 213 on the outside thereof will generate a corresponding induced electromotive force, and under the connection of each conductor 214, the induced current will flow through each corresponding source current coil 205 and branch coil 206, respectively, generating a magnetic field at the iron core 208, causing the iron core 208 to be magnetized. Without considering the line loss, since the current flowing through the power supply side cable is the sum of the current flowing through the user side cable, the magnitude of the induced current flowing through the source current coil 205 should be the sum of the magnitudes of the induced currents flowing through each branch coil 206, that is, the strength of the superimposed magnetic field generated by each branch coil 206 at the iron core 208 in the mounting seat 204 is the same as the strength of the magnetic field generated by the source current coil 205 at the iron core 208 in the winding drum 203;

[0071] By adjusting the air pressure on both sides of the sliding plate 202 as mentioned above, the deviation of the magnetic repulsion force on both sides of the permanent magnet 209 caused by line loss can be compensated, and the deviation of the magnetic field strength generated at the iron core 208 can be equivalently compensated. When no electricity theft occurs, the line loss is discarded, and the current on the power supply side is the same as the current on the user side. At this time, the difference in repulsion force on both sides of the sliding plate 202 is not enough to overcome the air pressure on both sides, and it will maintain a relatively stable state. When electricity theft occurs, since the current on the user side is less than the current on the power supply side, the magnetic repulsion force given to the permanent magnet 209 by the iron core 208 on one side of the mounting seat 204 is reduced. At this time, the difference in repulsion force becomes larger and is sufficient to overcome the air pressure on the end face of the sliding plate 202. The permanent magnet 209 will drag the sliding plate 202 to move toward the side of the mounting seat 204 under the action of the repulsive force, causing the sliding rod 215 to press against the signal switch 217 on one side of the mounting seat 204, and the signal switch 217 will send an electricity theft warning signal to the external control terminal;

[0072] If the connection between the source coil 205, the branch coil 206 and the mutual inductance coil 213 is violently cut off during operation, the magnetic field at the iron core 208 disappears, and the magnetic field force on the permanent magnet 209 disappears. In the aforementioned adjustment process, in order to compensate for the line loss, the air pressure on both ends of the sliding plate 202 is not used. At this time, under the action of the pressure difference, the sliding plate 202 will drive the sliding rod 215 to move to the side of the winding drum 203, causing the signal switch 217 on the side of the winding drum 203 to be triggered, and the signal switch 217 will send a power theft warning signal to the external control terminal;

[0073] The first thing to do in order to destroy the device by force is to open the door of the external meter box. After the door of the external meter box is opened, the screw rod 320 loses the restriction of the door, and the strip plate 318 slides under the action of air pressure, and the hydraulic pressure inside the movable groove 316 is pressed into the sliding groove 302, forcing the circular plug 308 to overcome the top air pressure and rise under the action of hydraulic pressure, so that the guide rod 309 no longer presses the induction switch 311;

[0074] Even if the electricity thief bypasses the step of opening the box door, when he cuts off the connection between the source coil 205, the branch coil 206 and the mutual inductance coil 213, the telescopic tube 312 cannot be displaced due to the limiting effect of the airbag ring 305. No matter he destroys the telescopic tube 312, punctures the airbag ring 305 or cuts off the protective tube 210, it will cause the air flow inside the sliding groove 302 to leak, causing the air pressure on the top of the circular plug 308 to decrease. At this time, under the compression of the compression spring 310, the circular plug 308 of the compression spring 310 will rise, so that the guide rod 309 no longer presses the induction switch 311. At this time, the induction switch 311 will send an electricity theft signal to the external control terminal to achieve dual monitoring and identification.
