Two sleeves 38 are sleeved outside the barrel 394, coil springs 395 are arranged in the two sleeves 38, one end of each coil spring 395 is fixedly connected to the inner side wall of the corresponding sleeve 38, and the other end of each coil spring 395 is connected to the outer wall of the barrel 394. Two first electric push rods 396 are installed on the top of the barrel 394, and the first electric push rods 396 are used for connecting and separating the barrel 394 and the output end of the motor 32. An induction switch is installed on the outer side wall of the barrel 394. By twisting the coil spring 395 to contract its inner ring, the induction switch can be triggered, and the induction switch is used to control the start of the first electric push rod 396 and the second electric push rod 397. Two slide rails 33 are formed in the top of the electric meter housing 1, strong magnets are installed in the two slide rails 33, the strong magnets are located at the ends of the two slide rails 33 away from each other, vertical rods 35 are inserted into the two slide rails 33 respectively, a telescopic rod 34 is connected between the outer part of the vertical rod 35 and the outer part of the sleeve 38. Columns 391 are fixedly connected to the bottoms of the two vertical rods 35 respectively. Induction sheets 393 are installed on the opposite sides of the two columns 391. A rubber plate 39 is connected to the repulsive sides of the two columns 391. The rubber plate 39 is located outside the detection part 2. There is a gap between the rear surface of the detection part 2 and the electric meter housing 1. The rubber plate 39 penetrates through the gap and fills the gap between the detection part 2 and the electric meter housing 1. A heat shrinkable sheet 301 is arranged on the inner wall of the rubber plate 39;
[0026] A protection switch 302 is installed between the rubber plate 39 and the heat shrinkable sheet 301. Two chutes 392 are formed in the bottom of the electric meter housing 1, and the bottoms of the two columns 391 are respectively inserted into the two chutes 392.

[0027] The sensing component 4 includes a fixed rod 43. One end of the fixed rod 43 away from the support frame 31 is fixedly connected with a guide rail 44.

[0029] Embodiment 1
[0030] Specifically, the staff connects the detection portion 2 and the meter housing 1 and installs them in the meter cabinet for use. When a fault occurs in the meter, the detection portion 2 will detect the fault condition of the meter and transmit the fault condition to the monitoring room through the controller. If the staff cannot handle the fault condition of the meter in time, the photovoltaic cell 41 senses the environment around the meter. When the ambient brightness is high, the photovoltaic cell 41 is irradiated by light and transmits the data to the controller. The controller controls the buzzer 36 to be energized, and the buzzer 36 emits a warning sound to attract the attention of the staff. If the position where the meter is installed has a low brightness and the photovoltaic cell 41 is weakly irradiated by light, the controller controls the warning light 37 to turn on while controlling the buzzer 36, so that the staff can find the faulty meter in time in the dim environment and perform repairs.
[0031] Embodiment 2
[0032] Specifically, the protection component 3 has two states: open and protection;
[0033] When in the open state, both columns 35 are located at the separated ends of the two slide rails 33, and the strong magnets installed inside the slide rails 33 attract the two columns 35. At the same time, one end of the telescopic rod 34 is pulled by the column 35, and the other end of the telescopic rod 34 drives the sleeve 38 to rotate on the outer side wall of the barrel 394. Since the second electric push rod 397 inside the groove 399 is fully extended, its piston rod limits the fixed frame 398 and the barrel 394, so that the fixed frame 398 and the barrel 394 cannot rotate under the influence of the torsion of the disc spring 395. When the sleeve 38 drives one end of the disc spring 395 to rotate, the other end of the disc spring 395 remains stationary following the barrel 394, and the disc spring 395 is in a tensile torsion state. At this time, the first electric push rod 396 is in a fully contracted state, and the output end of the motor 32 continues to rotate;
[0034] When the buzzer 36 is powered on, the first electric push rod 396 and the second electric push rod 397 are powered on simultaneously. The piston rod of the second electric push rod 397 fully contracts, and the limit on the fixed frame 398 is cancelled. The piston rod of the first electric push rod 396 extends and fits on the output end of the motor 32. The output end of the motor 32 rotates slowly. When the piston rod of the first electric push rod 396 extends, it squeezes the output end of the motor 32, so that the piston rod of the first electric push rod 396 and the output end of the motor 32 are squeezed and connected. The output end of the motor 32 drives the first electric push rod 36, the barrel 394 and the fixed frame 398 to rotate synchronously. Since the other end of the disc spring 395 is fixedly connected to the inner side wall of the sleeve 38, when the barrel 394 drives one end of the disc spring 395 to rotate, the disc spring 395 rotates and contracts. The inner ring of the disc spring 395 contracts and squeezes and triggers the induction switch installed on the outer side wall of the barrel 394. The induction switch controls the contraction of the limit block. At this time, the limits on both columns 35 are cancelled. At this time, the torsion of the disc spring 395 drives the sleeve 38 to rotate on the outer side wall of the barrel 394, and the sleeve 38 drives the telescopic rod 34 and the vertical rod 35 to move in the opposite direction. The two vertical rods 35 drive the two columns 391 to approach each other, and the two columns 391 drive the two induction sheets 393 to fit, thereby controlling the contraction of the first electric push rod 396, so that the output end of the motor 32 is separated from the barrel 394, and the second electric push rod 397 extends to limit the fixed frame 398 and the barrel 394;
[0035] At this time, the protection component 3 is switched from the open state to the protection state, and the detection part 2 is wrapped by the rubber plate 39 and the heat shrinkable sheet 301, so as to isolate the detection part 2 and avoid the situation that the faulty electric meter affects the adjacent electric meters;
[0036] The protection status of the electricity meter will be switched through the above - mentioned situations. At the same time, the staff can manually set it to the protection status. The reason for automatic switching is that the electricity meter fails, and the reason for manual setting is that the electricity meter is used in a harsh environment. When the protection component 3 is in the protection status, if the temperature of the electricity meter rises during the waiting for fault repair or the electricity meter generates excessive heat during normal use due to large power consumption, the heat - shrinkable sheet 301 will shrink when heated, thus attaching and wrapping the electricity meter. Since the heat - shrinkable sheet 301 and the rubber plate 39 are supported by the arc - shaped plate 5 and the water pipe 6, a certain gap is generated between the rubber plate 39 and the detection part 2. When the heat - shrinkable sheet 301 wraps the electricity meter, the position of the rubber plate 39 remains unchanged, and the heat - shrinkable sheet 301 gradually shrinks, thus triggering the protection switch 302 between the rubber plate 39 and the heat - shrinkable sheet 301. The protection switch 302 controls the solenoid valve to open, and the external water supply mechanism circulates cooling water through the water pipe 6, thus controlling the temperature of the detection part 2;
[0037] If the electricity meter explodes due to excessive temperature, the heat - shrinkable sheet 301 will tightly wrap it, preventing the fragments of the electricity meter from splashing and damaging adjacent electricity meters. At the same time, the rubber plate 39 plays the role of fire - resistance and heat - insulation.
[0038] Embodiment Three
[0039] Specifically, since the output end of the motor 32 rotates continuously, the output end of the motor 32 drives the connecting rod 42 to rotate continuously. When the connecting rod 42 rotates to one side of the scraper 45, the connecting rod 42 drives the scraper 45 to slide on the guide rail 44. While sliding, the scraper 45 scrapes the dust on the surface of the photovoltaic cell 41, avoiding the influence of dust adsorption on the detection effect of the photovoltaic cell 41 when the electricity meter is installed in a harsh environment.
