Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0024] Embodiment 1 like Figure 1-Figure 10 As shown, an electric energy metering box equipped with an anti-electricity theft device includes a box body 1, and one side of the box body 1 is cleverly divided into a first installation space 2 and a second installation space 3. The two spaces are used to install a main switch 6, a secondary switch 8, a household switch 9 and an electric meter, respectively, to ensure the normal power supply and metering. In order to protect these key components, a second protective door 5 and a first protective door 4 are hinged in the first installation space 2 and the second installation space 3, respectively. These protective doors not only play a protective role, but are also easy to open and close, making it convenient for staff to carry out daily inspections and maintenance.

[0025] In order to facilitate the locking and unlocking of the protective door, a rotating shaft 32 is rotatably provided on one side of the box body 1, and a baffle 7 is rotatably provided on the outer wall of the rotating shaft 32. When the protective door needs to be closed, the baffle 7 only needs to be rotated to a position corresponding to the rectangular opening 11 on the first fixed block 10, and then the protective door is pushed to close, and the baffle 7 can pass through the rectangular opening 11 to play a locking role. In order to more easily rotate the baffle 7, a plug-in column 33 for assisting is plugged into the outer end of the rotating shaft 32. The user can conveniently rotate the baffle 7 through the plug-in column 33 to achieve quick locking and unlocking of the protective door. At the same time, arc grooves 36 are provided on the sides of the second protective door 5 and the first protective door 4 that are close to each other, which helps to cooperate more smoothly when closing and reduce friction and resistance.

[0026] In order to further improve the anti-electricity theft capability, 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 auxiliary switch 8 and the home switch 9 respectively, and are used to provide all-round protection for the terminals on the switches. In particular, the second protection frame 13 located in the middle has baffles 14 fixed on the top and bottom for protecting the connecting wires. These baffles 14 effectively prevent electricity thieves from stealing electricity by damaging the connecting wires.

[0027] In order to realize the automatic locking and unlocking function of the protection 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 protection frame 12 and the two second protection frames 13 is opened 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 protection frame 12 and the two second protection frames 13. When the sliding frame 18 descends, the plug rod 24 will be inserted into the clamping block 44 to fix the protection frame. When the sliding frame 18 rises, the plug rod 24 will be pulled out of the clamping block 44 to unlock the protection frame. In order to realize the lifting and lowering 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 second fixed block 20 above, and the second fixed block 20 is slidably connected to the first installation space 2 through the guide rod 21 and the third fixed block 22. In this way, the telescopic movement of the electric push rod 19 can stably drive the sliding frame 18 to rise and fall, thereby realizing the locking and unlocking functions of the protection frame.

[0028] In order to monitor the breakage of the protective frame, the present embodiment further provides a monitoring component in the first protective frame 12 and the second protective frame 13. 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 provided on the inner wall of the rubber plate 26, dividing the rubber plate 26 into a second cavity 29 and a first cavity 28. Ammonia is provided in the second cavity 29, and a gas sensor 31 for monitoring ammonia is fixedly provided on one side inner wall of the first cavity 28. When the protective frame is damaged by external force, ammonia will leak into the first cavity 28 and be detected by the gas sensor 31. In this way, the staff can promptly discover and deal with the breakage of the protective frame to prevent the occurrence of electricity theft.

[0029] In order to further improve the reliability of monitoring, a gas bag 30 for pressurizing the gas is fixedly arranged in the second cavity 29. In the initial state, the gas bag 30 is compressed by the high-pressure ammonia gas. When the glass plate 27 is broken, the gas bag 30 can ensure that the ammonia gas can quickly leak into the first cavity 28 when the protective frame is damaged, thereby improving the detection sensitivity of the gas sensor 31.

[0030] In order to facilitate the processing and response of the signal from the gas sensor 31, a controller 17 is fixedly installed on one side of one baffle 14. A buzzer 15 and an alarm light 16 corresponding to the gas sensor 31 are fixedly installed on the inner wall of one side of the second protective door 5. The buzzer 15, the alarm light 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 sound an alarm and light up the alarm light 16 to alert the staff, and at the same time, the controller 17 can send a signal to the power supply bureau.

[0031] Embodiment 2 Reference Figure 1-Figure 10 The present invention provides a new technical solution, an electric energy metering box with an anti-electricity theft device. In order to ensure that the sliding frame 18 moves up and down at the right time, the embodiment also opens a rotation groove 34 on one side of the box body 1, and a rotating disk 35 located in the rotation groove 34 is fixedly sleeved on the outer wall of the rotating shaft 32. A cutout 37 is opened on one side of the rotating disk 35, and a limit block 25 used in conjunction with the cutout 37 is fixedly set on one side of the sliding frame 18. When the rotating disk 35 rotates with the rotating shaft 32, the cutout 37 will cooperate with the limit block 25, so that the rotating shaft 32 cannot rotate, thereby locking the rotating shaft 32.

[0032] In order to realize the automatic control function of the electric push rod 19, the present embodiment also fixes a fixing seat 38 in the box body 1, and embeds a control switch 39 on one side of the fixing seat 38. The control switch 39 is connected to the controller 17 and the electric push rod 19 through a wire. The plug-in column 33 is used in conjunction with the control switch 39 through a connecting piece, and the electric push rod 19 is controlled to telescopically move by the control switch 39 during the rotation process. Specifically, the connecting piece includes a wedge block 42 and a positioning block 43 fixed at one end of the plug-in 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 plug-in column 33 is inserted into the rotating shaft 32, the wedge block 42 will be stuck in the second rectangular hole 40, and the positioning block 43 will be stuck in the third rectangular hole 41. As the plug-in column 33 rotates, the wedge block 42 will push the contact of the control switch 39 to close or open, thereby controlling the telescopic movement of the electric push rod 19. In this way, the automatic locking and unlocking function of the protective frame during the closing and opening process can be realized, which greatly improves the safety and anti-electricity theft capability of the electric energy metering box.

[0033] A method for using an electric energy meter box equipped with an anti-electricity theft device comprises the following steps: S1. When opening, first, insert the wedge block 42 and the positioning block 43 at one end of the plug-in column 33 into the corresponding second rectangular hole 40 and the third rectangular hole 41 and rotate them. During the rotation, the electric push rod 19 is activated by the control switch 39 to drive the sliding frame 18 to move downward, fix the first protection frame 12 and the second protection frame 13, and at the same time drive the blocking rod 7 to rotate, and release the fixation of the first protection door 4 and the second protection door 5; S2, then open the first protection door 4 and the second protection door 5, at this time the paddles on the main switch 6, the auxiliary switch 8 and the entrance switch 9 are exposed; S3, when someone forcibly connects the power, the first protection frame 12 and the second protection frame 13 will be pulled to break the glass plate 27 inside. 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, and an alarm will be sounded through the buzzer 15 and the alarm light 16; S4. When closing is required, the first protective door 4 and the second protective door 5 are closed, and the plug-in column 33 is rotated in the opposite direction, which can drive the blocking rod 7 to rotate in the opposite direction to fix the first protective door 4 and the second protective door 5, and start the electric push rod 19 to drive the sliding frame 18 to move upward, thereby releasing the fixation of the first protective frame 12 and the second protective frame 13.

[0034] Working principle: when opening, first, insert the wedge block 42 and the positioning block 43 at one end of the plug-in column 33 into the corresponding second rectangular hole 40 and the third rectangular hole 41 and rotate them. During the rotation, the control switch 39 is pressed by the wedge block 42, which can start the electric push rod 19 to extend and drive the second fixed block 20 to move downward. The downward movement of the second fixed block 20 can drive the sliding frame 18 to move downward, and drive the plug rod 24 to insert into the corresponding clamping block 44, which can fix the first protective frame 12 and the second protective frame 13, and at the same time can drive the limit block 25 to move downward, so that the limit block 25 is away from the incision 37. Continuing to rotate can drive the stop rod 7 to rotate. During the rotation of the stop rod 7, it can be separated from the rectangular opening 11 on the first fixed block 10, and the fixation of the first protective door 4 and the second protective door 5 is released; Then open the first protection door 4 and the second protection door 5, at this time the paddles on the main switch 6, the auxiliary switch 8 and the entrance switch 9 are exposed, and the power can be disconnected; When someone forcibly connects the power, the first protection frame 12 and the second protection frame 13 will be pulled. When the first protection frame 12 and the second protection frame 13 are stressed, the glass plate 27 inside will be broken. 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 alarm light 16 to sound an alarm, and it can also be monitored online. When it is necessary to close, the first protective door 4 and the second protective door 5 are closed, and the plug-in column 33 is rotated in the opposite direction, which can drive the blocking rod 7 to rotate in the opposite direction to fix the first protective door 4 and the second protective door 5. During the process of the plug-in column 33 driving the rotating shaft 32 to rotate in the opposite direction, the control switch 39 can be pressed again, and the electric push rod 19 is started to retract and drive the sliding frame 18 to move upward, thereby 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 cutout 37. At this time, when only the rotating shaft 32 is rotated, the limit block 25 can cooperate with the cutout 37 to limit the rotating shaft 32, so that the rotating shaft 32 cannot be rotated; 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-in column 33 can be directly rotated to drive the blocking rod 7 to rotate, and during the rotation, the electric push rod 19 can be controlled to retract, driving the sliding frame 18 to move upward, thereby 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 be rotated, and then power can be connected and maintenance can be carried out.

[0035] 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 commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
