Through the setting of the protective enclosure, it is convenient to be placed inside the fixed limit plate and fixed and installed by bolts, preventing the problem of inconvenient fixing and maintenance when directly installed on the wall, and facilitating the insertion and locking of the closing door to be flush after closing, preventing the possibility of stealing electricity personnel from prying. However, this electric energy metering box still has the following defects.

[0042] The usage method of the intelligent safety protection electric energy metering box of the present invention is as follows:

[0043] First, when the present invention is installed and used, the metering box shell 1 is fixed on the installed wall by using expansion bolts. An electricity meter is installed inside the metering box shell 1, and then the wire harness enters the metering box shell 1 through the inlet hole 17 and is connected to the electricity meter. Then, the wire harness exits through the outlet hole 18 to the electrical equipment. Push the top case 4, the top case 4 is hinged and closed with the metering box shell 1. Push the bottom case 3, the bottom case 3 is hinged and closed with the metering box shell 1. Push the protective case 2, the protective case 2 is hinged and closed with the metering box shell 1. Then, the wireless controller 31 is powered by the lithium battery 32. After the wireless controller 31 turns on the electromagnetic lock 41 and the electromagnetic lock 41 generates magnetic force when electrified, the electromagnetic lock 41 magnetically fixes the top case 4, the bottom case 3, and the protective case 2 to realize the closing and locking operation of the metering box shell 1.

[0044] Secondly, when the present invention performs distribution detection, when a power thief uses a crowbar or other tool to strike the vibration protection shell 2, the vibration of the protection shell 2 is transmitted to the connecting strip 37 through the sensing column 38, the connecting strip 37 is transmitted to the linkage strip 34, the linkage strip 34 is transmitted to the vibration sensor 35, and the metering box shell 1 supports the support block 36, and the support block 36 supports the vibration sensor 35, and the vibration sensor 35 performs sensing. When the top shell 4 is struck, the top shell 4 can drive the contact pillar 40 to vibrate, the contact pillar 40 drives the connecting strip 39 to vibrate, the connecting strip 39 drives the connecting strip 37 to vibrate, and the connecting strip 37 drives the linkage strip 34 to vibrate on the vibration sensor 35. When the bottom shell 3 is struck, the bottom shell 3 drives the contact shaft 33 to vibrate, the contact shaft 33 drives the linkage strip 34 to vibrate, and the linkage strip 34 vibrates on the vibration sensor 35. At the same time, the vibration sensor 35 can perform vibration sensing on the protection shell 2, the bottom shell 3 and the top shell 4, so as to timely know that the protection shell 2, the bottom shell 3 and the top shell 4 are violently disassembled by external personnel for power theft operations.

[0045] Then, when the present invention performs tilt safety protection, the reduction motor 16 is started through the wireless controller 31, the reduction motor 16 drives the screw rod 10 to rotate inside the sliding frame 5, the screw rod 10 drives the articulated sleeve block 11 to move downward along the inner wall of the sliding frame 5 under the action of the thread driving force, the articulated sleeve block 11 drives the connecting shaft 12 to move downward, the connecting shaft 12 drives the top end of the sleeve rod 13 to move downward, and the sleeve rod 13 drives the push shaft 14 to rotate clockwise, and the push shaft 14 drives the articulated block 15 to rotate clockwise. At the same time, the articulated block 15 drives the protective strip 8 to rotate clockwise, the protective strip 8 rotates clockwise along the outer wall of the support shaft 7, and the sliding frame 5 supports the concave block 6, and the concave block 6 provides a supporting force for the support shaft 7, so that the protective strip 8 rotates and moves clockwise, and the protective strip 8 is inserted into the groove inside the inclined groove strip 9, so as to realize plug-in reinforcement of the inclined groove strip 9.

[0046] In this way, when a power thief pries the protection shell 2, the connecting shaft 12 is supported by the articulated sleeve block 11, the sleeve rod 13 is supported by the connecting shaft 12, the push shaft 14 is supported by the sleeve rod 13, the articulated block 15 is supported by the push shaft 14, and the articulated block 15 provides a force for the protective strip 8. At the same time, the sliding frame 5 supports the concave block 6, the concave block 6 supports the support shaft 7, and the support shaft 7 provides a stable supporting force for the protective strip 8. In this way, the protective strip 8 provides a supporting force for the inclined groove strip 9, and the inclined groove strip 9 provides an inclined stable protection operation for the protection shell 2, and it is difficult to pry open the protection shell 2.

[0047] Meanwhile, when the present invention performs linkage safety protection, the electric cylinder 20 is started through the wireless controller 31. The electric cylinder 20 pushes the pressure sensor 21, and the pressure sensor 21 pushes the linkage rack 22 to move upward. The linkage rack 22 drives the linkage gear 23 to rotate clockwise by forty degrees. In this way, the linkage gear 23 rotates clockwise by forty degrees along the outer wall of the positioning shaft 24. At the same time, the linkage gear 23 drives the limit sleeve strip 25 to rotate clockwise by forty degrees, and the limit sleeve strip 25 rotates clockwise by forty degrees along the outer wall of the positioning shaft 24. The limit sleeve strip 25 rotates clockwise by forty degrees and is inserted into the inner wall of the inclined groove strip 19. Thus, the metering box shell 1 supports the positioning shaft 24, the positioning shaft 24 limits the linkage gear 23, the limit sleeve strip 25 supports the inclined groove strip 19, and the inclined groove strip 19 realizes inclined reinforcement of the bottom shell 3. In this way, the bottom shell 3 realizes stable inclined reinforcement, avoiding the bottom shell 3 from being pried open.

[0048] Meanwhile, the linkage rack 22 drives the driven gear 26 to rotate clockwise by forty degrees. The driven gear 26 rotates clockwise by forty degrees on the outer wall of the support shaft 27, and the driven gear 26 drives the flipping sleeve strip 28 to rotate clockwise by forty degrees. The flipping sleeve strip 28 drives the locking strip 29 to rotate clockwise by forty degrees. The locking strip 29 rotates clockwise by forty degrees and is inserted into the inside of the concave groove strip 30. When the pressure value sensed by the pressure sensor 21 is the same as the pressure value set by the wireless controller 31, the electric cylinder 20 is closed through the wireless controller 31. In this way, the locking strip 29 supports the concave groove strip 30, and the concave groove strip 30 realizes the inclined reinforcement operation of the top shell 4. In this way, when the top shell 4 is pried by external electricity theft personnel, inclined reinforcement and anti-theft are realized inside the top shell 4, avoiding the top shell 4 from being pried open, and thus the safety protection performance is better.
