[0047] Embodiment 1

[0048] As Figures 1 - 10 shown, an electric energy metering box with an anti - electricity - theft device installed includes a box body 1. One side of the box body 1 is ingeniously divided into a first installation space 2 and a second installation space 3. These two spaces are respectively used for installing the main switch 6, the sub - switch 8, the household - entry switch 9 and the electric meter, ensuring the normal progress of power supply and metering. To protect these key components, a second protection door 5 and a first protection door 4 are respectively hinged in the first installation space 2 and the second installation space 3. These protection doors not only play a protective role, but also are convenient to open and close, facilitating daily inspection and maintenance by staff.

[0049] To facilitate the locking and unlocking of the protection doors, a rotating shaft 32 is rotatably arranged on one side of the box body 1, and a stop lever 7 is rotatably arranged on the outer wall of the rotating shaft 32. When it is necessary to close the protection door, just rotate the stop lever 7 to a position corresponding to the rectangular opening 11 on the first fixed block 10, and then push the protection door to close. The stop lever 7 can pass through the rectangular opening 11 to play a locking role. To rotate the stop lever 7 more easily, a plug - in column 33 for assistance is inserted at the outer end of the rotating shaft 32. The user can conveniently rotate the stop lever 7 through the plug - in column 33 to achieve the quick locking and unlocking of the protection door. At the same time, arc - shaped grooves 36 are respectively opened on the mutually approaching sides of the second protection door 5 and the first protection door 4, which helps to cooperate more smoothly when closing, reducing friction and resistance.

[0050] To further improve the anti - electricity - theft ability, a first protection frame 12 and two second protection frames 13 are hinged on the inner wall of one side of the first installation space 2. These protection frames correspond to the main switch 6, the sub - switch 8 and the household - entry switch 9 respectively, and are used to provide all - round protection for the wiring terminals on the switches. Especially for the second protection frame 13 in the middle, baffles 14 for protecting the connecting wires are fixedly arranged at both the top and the bottom. These baffles 14 effectively prevent electricity thieves from stealing electricity by damaging the connecting wires.

[0051] To achieve the automatic locking and unlocking functions of the protective frame, a locking mechanism is provided. The locking mechanism includes a sliding frame 18 slidably arranged on the inner wall of one side of the first installation space 2. A first rectangular hole 23 corresponding to the first protective frame 12 and two second protective frames 13 is formed on one side of the sliding frame 18. A plug rod 24 is fixedly arranged on the top wall of the first rectangular hole 23, and a clamping block 44 corresponding to the first rectangular hole 23 is fixedly arranged on one side of the first protective frame 12 and the two second protective frames 13. When the sliding frame 18 descends, the plug rod 24 will insert into the clamping block 44 to fix the protective frame. When the sliding frame 18 ascends, the plug rod 24 will be pulled out from the clamping block 44 to unlock the protective frame. To achieve the lifting movement of the sliding frame 18, an electric push rod 19 is arranged on the inner wall of one side of the first installation space 2 as a driving component. The output end of the electric push rod 19 is fixedly connected to the upper second fixing block 20, and the second fixing block 20 is slidably connected to the first installation space 2 through a guide rod 21 and a third fixing block 22. In this way, the telescopic movement of the electric push rod 19 can stably drive the sliding frame 18 to lift and lower, realizing the locking and unlocking functions of the protective frame.

[0052] To monitor the breakage of the protective frame, a monitoring component is also arranged in the first protective frame 12 and the second protective frame 13 in this embodiment. Specifically, the first protective frame 12, the second protective frame 13 and the baffle 14 are all made of a hollow rubber plate 26. A glass plate 27 is fixedly arranged on the inner wall of the rubber plate 26, dividing the inside of the rubber plate 26 into a second cavity 29 and a first cavity 28. Ammonia gas is arranged in the second cavity 29, and a gas sensor 31 for monitoring ammonia gas is fixedly arranged on the inner wall of one side of the first cavity 28. When the protective frame is damaged by an external force, the ammonia gas will leak into the first cavity 28 and be detected by the gas sensor 31. In this way, the staff can timely discover and handle the breakage of the protective frame, preventing the occurrence of electricity theft behavior.

[0053] To further improve the reliability of the monitoring, an airbag 30 for pressurizing the gas is fixedly arranged in the second cavity 29. In the initial state, the airbag 30 is compressed by high-pressure ammonia gas. When the glass plate 27 is broken, the airbag 30 can ensure that when the protective frame is damaged, the ammonia gas can quickly leak into the first cavity 28, thereby improving the detection sensitivity of the gas sensor 31.

[0054] To facilitate the processing and response to the signals emitted by the gas sensor 31, a controller 17 is fixedly arranged on one side of one of the baffles 14. A buzzer 15 and an alarm lamp 16 corresponding to the gas sensor 31 are fixedly arranged on the inner wall of one side of the second protective door 5. The buzzer 15, the alarm lamp 16, and the gas sensor 31 are all connected to the controller 17 through wires. When the gas sensor 31 detects ammonia, the controller 17 will control the buzzer 15 to emit an alarm sound and light up the alarm lamp 16 to alert the staff, and at the same time, a signal can be sent to the power supply bureau through the controller 17.

[0055] Embodiment 2

[0056] Referring to Figures 1 - 10 , the present invention provides a new technical solution, an electric energy metering box equipped with an anti-stealing electricity device. In order to ensure the lifting and moving of the sliding frame 18 at the correct timing, a rotating groove 34 is also opened on one side of the box body 1 in this embodiment, and a rotating disk 35 located in the rotating groove 34 is fixedly sleeved on the outer wall of the rotating shaft 32. A notch 37 is opened on one side of the rotating disk 35, and a limiting block 25 that cooperates with the notch 37 is fixedly arranged on one side of the sliding frame 18. When the rotating disk 35 rotates with the rotating shaft 32, the notch 37 will cooperate with the limiting block 25, making the rotating shaft 32 unable to rotate, so as to lock the rotating shaft 32.

[0057] In order to realize the automatic control function of the electric push rod 19, a fixed seat 38 is also fixedly arranged in the box body 1 in this embodiment, and a control switch 39 is embedded on one side of the fixed seat 38. The control switch 39 is connected to the controller 17 and the electric push rod 19 through wires. The insertion column 33 cooperates with the control switch 39 through a connecting member, and the electric push rod 19 is controlled to expand and contract during the rotation process. Specifically, the connecting member includes a wedge block 42 and a positioning block 43 fixedly arranged at one end of the insertion column 33, and a second rectangular hole 40 and a third rectangular hole 41 opened at the outer end of the rotating shaft 32. When the insertion column 33 is inserted into the rotating shaft 32, the wedge block 42 will be stuck into the second rectangular hole 40, and the positioning block 43 will be stuck into the third rectangular hole 41. As the insertion column 33 rotates, the wedge block 42 will push the contact of the control switch 39 to close or open, thereby controlling the expansion and contraction of the electric push rod 19. In this way, the automatic locking and unlocking functions during the closing and opening processes of the protective frame can be realized, greatly improving the safety and anti-stealing electricity ability of the electric energy metering box.

[0058] A usage method of an electric energy metering box equipped with an anti-stealing electricity device includes the following steps:

[0059] S1. When opening, first, insert the wedge block 42 and the positioning block 43 at one end of the insertion column 33 into the corresponding second rectangular hole 40 and third rectangular hole 41 and rotate. During the rotation process, start the electric push rod 19 to drive the sliding frame 18 to move downward by controlling the switch 39, fix the first protection frame 12 and the second protection frame 13, and at the same time drive the blocking rod 7 to rotate to release the fixation of the first protection door 4 and the second protection door 5;

[0060] S2. Then open the first protection door 4 and the second protection door 5. At this time, the sliders on the main switch 6, the sub-switch 8 and the household switch 9 are exposed;

[0061] S3. When someone forcibly connects electricity, the first protection frame 12 and the second protection frame 13 will be pulled, causing the glass plate 27 inside to break. At this time, the gas in the second cavity 29 will enter the first cavity 28 under the pressure of the airbag 30 and be detected by the gas sensor 31. At the same time, an alarm will be issued through the buzzer 15 and the alarm lamp 16;

[0062] S4. When it needs to be closed, close the first protection door 4 and the second protection door 5, and rotate the insertion column 33 in the reverse direction, which can drive the blocking rod 7 to rotate in the reverse direction to fix the first protection door 4 and the second protection door 5, and start the electric push rod 19 to drive the sliding frame 18 to move upward to release the fixation of the first protection frame 12 and the second protection frame 13.

[0063] Working principle: When opening, first, insert the wedge block 42 and the positioning block 43 at one end of the insertion column 33 into the corresponding second rectangular hole 40 and third rectangular hole 41 and rotate. During the rotation process, press the control switch 39 through the wedge block 42 to start the electric push rod 19 to extend and drive the second fixing block 20 to move downward. The downward movement of the second fixing block 20 can drive the sliding frame 18 to move downward and drive the insertion rod 24 to insert into the corresponding clamping block 44 to fix the first protection frame 12 and the second protection frame 13. At the same time, it can drive the limiting block 25 to move downward, making the limiting block 25 away from the notch 37. Continuing to rotate can drive the blocking rod 7 to rotate. During the rotation of the blocking rod 7, it can break away from the rectangular opening 11 on the first fixing block 10 to release the fixation of the first protection door 4 and the second protection door 5;

[0064] Then open the first protection door 4 and the second protection door 5. At this time, the sliders on the main switch 6, the sub-switch 8 and the household switch 9 are exposed, and the power can be disconnected;

[0065] When someone forcibly connects the power supply, the first protective frame 12 and the second protective frame 13 will be toggled. When the first protective frame 12 and the second protective frame 13 are stressed, the glass plate 27 inside will break. At this time, the gas in the second cavity 29 will enter the first cavity 28 under the pressure of the airbag 30 and be detected by the gas sensor 31. At the same time, the controller 17 controls the buzzer 15 and the warning light 16 to give an alarm, and it can also be monitored by networking;

[0066] When it needs to be closed, close the first protective door 4 and the second protective door 5, and rotate the plug post 33 in the reverse direction, which can drive the stop lever 7 to rotate in the reverse direction to fix the first protective door 4 and the second protective door 5. During the process that the plug post 33 drives the rotating shaft 32 to rotate in the reverse direction, the control switch 39 can be pressed again, and the electric push rod 19 is started to retract to drive the sliding frame 18 to move upward, releasing the fixation of the first protective frame 12 and the second protective frame 13, and at the same time driving the limit block 25 to move upward and get stuck on one side of the notch 37. At this time, when only the rotating shaft 32 is rotated, the limit block 25 can cooperate with the notch 37 to limit the rotating shaft 32, making it impossible to rotate the rotating shaft 32;

[0067] When it is necessary to open the first protective frame 12 and the second protective frame 13, after the first protective door 4 and the second protective door 5 are opened, the plug post 33 can be directly rotated to drive the stop lever 7 to rotate, and during the rotation process, the electric push rod 19 is controlled to retract, driving the sliding frame 18 to move upward, releasing the fixation of the first protective frame 12 and the second protective frame 13. At this time, the first protective frame 12 and the second protective frame 13 can rotate, and then the power connection and maintenance can be carried out.

[0068] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller 17 and the electric push rod 19 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here.
