[0002] Electric meter boxes are a common equipment in modern times, usually used for the installation and protection of electric meters. Electric meter boxes are usually made of metal materials, which have the characteristics of chemical corrosion resistance, light weight, high strength and good fatigue resistance. Electric meter boxes are generally installed in modern buildings; 1. Most of the existing meter boxes are designed with relatively compact internal structures to reduce their overall volume during installation and use, which results in a relatively narrow internal space of the meter box. When the meter inside the meter box fails, it is inconvenient for the staff to maintain it; 2. Most of the existing meter boxes are fixed on the building wall by expansion screws. When the meter box needs to be removed from the wall for maintenance, the screw holes on the wall will be damaged.

Two groups of transmission screws 501 are arranged inside the control box 5, and the two groups of transmission screws 501 rotate in the same direction. A second rectangular hole matching the size of the connecting frame 504 is opened at the top of the control box 5; Through the above technical solution, the two sets of transmission screws 501 can be rotated simultaneously by rotating the No. 1 servo motor 401, and the two sets of transmission screws 501 rotate in the same direction. At this time, the rotation of the transmission screws 501 can be used to make the push slider 502 move horizontally. In this way, the meter mounting plate 505 can be moved toward the outside of the meter box body 1, so that the meter installed on the surface of the meter mounting plate 505 can be moved toward the outside of the meter box body 1, which is convenient for maintenance of the meter. A solar panel 601 is fixedly mounted on the top of the supporting inclined plate 6, a second servo motor 602 is mounted on the top of the supporting inclined plate 6, and a power gear 603 is fixedly mounted on the output shaft of the second servo motor 602, a transmission rod 604 is mounted on the top of the supporting inclined plate 6, and a first driving gear 605 is fixedly mounted on the surface of the transmission rod 604, and a second driving gear 606 is fixedly mounted on one end of the transmission rod 604; A sliding screw 701 is installed inside the limit frame 7, a third driving gear 702 is fixedly installed on the surface of the sliding screw 701, a reciprocating slider 703 is installed on the surface of the sliding screw 701, a connecting slider 704 is fixedly installed on the surface of the reciprocating slider 703, and a cleaning scraper 705 is fixedly installed on the side of the connecting slider 704; A set of protection frames are arranged on the surface of the second servo motor 602, the transmission rod 604 is inserted through the protection frame, the surface of the power gear 603 is meshed with the surface of the first drive gear 605, the surface of the second drive gear 606 is meshed with the surface of the third drive gear 702, both ends of the sliding screw 701 are installed on the inner wall of the limit frame 7 through the bearing seat, the interior of the reciprocating slider 703 is provided with a second circular screw hole matching the size of the sliding screw 701, and the side of the limit frame 7 is provided with a third rectangular hole matching the size of the connecting slider 704; Through the above technical solution, the second servo motor 602 is used as the output power to drive the sliding screw 701 to rotate. When the sliding screw 701 rotates, the reciprocating slider 703 will move on its surface. As the reciprocating slider 703 moves, the cleaning scraper 705 can move back and forth. Since the bottom end of the cleaning scraper 705 is attached to the surface of the solar panel 601, the dust on the surface of the solar panel 601 can be cleaned when the cleaning scraper 705 moves.

[0021] Working principle: According to Figure 1-7 As shown, when the electric meter installed in the electric meter box body 1 needs to be maintained, the handle 102 is pulled to open the box door 101, and then the output gear 402 is driven to rotate by the rotation of the No. 1 servo motor 401. When the output gear 402 rotates, the transmission belt 403 can be rotated, and the rotation of the transmission belt 403 drives the two sets of transmission gears 503 to rotate at the same time. When the two sets of transmission gears 503 rotate, the two sets of transmission screws 501 can be rotated together. At this time, when the transmission screw 501 rotates, the push slider 502 can be moved, and the movement of the push slider 502 can be used to move the electric meter mounting plate 505 together, and the electric meter mounting plate 505 is moved toward the outside of the electric meter box body 1, so that the electric meter installed on the surface of the electric meter mounting plate 505 can be moved toward the outside of the electric meter box body 1, so that it is convenient to maintain the electric meter installed on the surface of the electric meter mounting plate 505. according to Figure 1-7As shown, when the meter box body 1 needs to be safely disassembled, the installation back plate 3 is fixedly installed on the wall by using expansion screws, and the meter box body 1 is fixed by using the installation slot 302. The disassembly button 303 can be pressed to make the disassembly button 303 slide horizontally, and the disassembly button 303 can be used to push the fixed card block 201 against it, so that the fixed card block 201 can be retracted and slid into the inside of the installation card block 2. At this time, the fixed card block 201 will no longer be engaged with the inner wall of the installation slot 302. At this time, the meter box body 1 is pulled upward, and the installation card block 2 can be slid out from the inside of the installation slot 302. In this way, the meter box body 1 can be disassembled more conveniently and quickly, and the installation back plate 3 is still firmly fixed on the wall. When the meter box body 1 needs to be reinstalled, the meter box body 1 can be installed and fixed by using the installation back plate 3. The meter box body 1 can be installed in this way without drilling additional holes on the wall to ensure the safety of the wall. according to Figure 1-7 As shown, when the dust attached to the surface of the solar panel 601 needs to be cleaned automatically and timely, the power gear 603 is driven to rotate by the rotation of the No. 2 servo motor 602. When the power gear 603 rotates, the No. 1 driving gear 605 can be driven to rotate, and the transmission rod 604 can be rotated at the same time. The No. 2 driving gear 606 can be rotated by the rotation of the transmission rod 604, and the No. 3 driving gear 702 can be driven to rotate by the No. 2 driving gear 606. When the No. 3 driving gear 702 rotates, the sliding screw 701 can be rotated. As the sliding screw 701 rotates, the reciprocating slider 703 can slide on its surface, and the connecting slider 704 can also slide. The sliding of the connecting slider 704 can make the cleaning scraper 705 slide. Since the bottom end of the cleaning scraper 705 is attached to the top of the solar panel 601, when the cleaning scraper 705 is attached to the top of the solar panel 601 and slides, the dust on the top of the solar panel 601 can be scraped and cleaned to ensure that the efficiency of the solar panel 601 in absorbing solar energy is not affected.
