Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, in particular to an anti-electricity theft meter box. Background Art

[0002] Electricity theft has long been a major problem for power supply companies, hindering the development of the power industry and posing a serious threat to safe electricity use. Current meter boxes have exposed components and exposed wiring. This allows access to the meter by opening the door. Residents can then tamper with the wiring and steal electricity. At the end of the month, they remove the wiring and restore the meter reading, making this difficult to detect. Currently, to prevent electricity theft, the market typically incorporates an alarm device within the meter box. Upon opening the door, the alarm automatically transmits an alarm signal to a remote monitoring center, alerting the meter box of any theft and allowing for inspection and repair. For example, patents No. 201710507450.3, titled "A Meter Box with Anti-Theft Alarm Function," and No. 201910967267.0, titled "A Low-Voltage Anti-Theft Smart Meter Box," disclose meter boxes with remote alarm capabilities. However, this type of meter box with remote alarms has many problems: 1. There is a serious lag, making it ineffective in preventing theft. In remote areas, for example, by the time staff arrive at the scene, the thief has already stolen electricity from the meter. Even if the thief is caught, it still takes a lot of time to repair the wiring. 2. There is a problem of not being able to detect the alarm signal in time. When there is no one in the monitoring room or no one is on duty in the middle of the night, the alarm signal cannot be detected in time and the theft cannot be prevented in time. 3. Staff must rush to the scene to prevent or rectify the situation as soon as possible, which increases time and cost. If alarms occur in multiple locations at the same time, additional staff will need to be dispatched, which undoubtedly increases labor costs. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems and provide an anti-electricity theft meter box, which divides the box into two chambers by a partition vertical plate. When electricity theft occurs, the maintenance port can be automatically closed, and then the electricity meter is hidden in the installation chamber, preventing electricity theft from the source to reduce the subsequent rectification and maintenance costs. At the same time, there is no need to require staff to rush to the alarm scene as soon as possible. Maintenance personnel can reply to the closed maintenance port when reading the electricity meter later, without the need to dispatch additional manpower, saving labor costs and time costs.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] This embodiment provides an anti-theft electricity meter box, such as Figures 1 to 8 As shown, it includes a box body 1 and an anti-electricity theft system.

[0032] The box body 1 is provided with a vertical partition board 3, which divides the box body 1 into a maintenance chamber at the front end and an installation chamber at the rear end. The installation chamber needs to be placed against the wall on this side, and can be hung on the wall or placed on the ground. An electric meter 4 is hung on the inner wall of the installation chamber on the side against the wall. The electric meter 4 is set according to the number of residents on the floor. When the number of electric meters 4 is large, they can be arranged in a matrix. Ventilation holes 6 are also provided on the inner wall of the installation chamber. A maintenance port 5 is provided on the partition board. The number of the maintenance ports 5 is consistent with the number of electric meters 4, and the positions of the maintenance ports 5 and the electric meters 4 correspond one to one, so that the electric meters 4 can be exposed. The size of the maintenance port 5 needs to ensure that the maintenance personnel can put their hands into the installation chamber to repair the electric meters 4. An inspection door 2 is hinged on the maintenance chamber by a hinge 25, and a door lock 8 is provided on the inspection door 2. An observation window 7 corresponding to the maintenance port 5 is provided on the inspection door 2. After the door lock 8 is locked, the display screen of the electricity meter 4 can be read from the outside of the inspection door 2 through the observation window 7 to obtain the meter reading without opening the inspection door 2.

[0033] The anti-electricity theft system includes an opening and closing device, a control device, and an employee card recognition device disposed within the installation chamber. The opening and closing device includes a first blocking portion, a second blocking portion, and a driving portion. The first blocking portion is used to block the maintenance opening 5, and the second blocking portion is used to block the ventilation opening 6. The driving portion is used to drive the first and second blocking portions. The driving portion is used to drive the first and second blocking portions, and the driving portion will only drive the first and second blocking portions after receiving a command. In the initial state, the maintenance port 5 is not blocked by the first blocking portion, and the ventilation port 6 is blocked by the second blocking portion. The heat brought by the electricity meter 4 in the installation chamber will be transferred into the maintenance chamber through the maintenance port 5 and then dissipated through the observation window 7. Then, when the driving unit receives the closing command, it will drive the first blocking portion to move to the maintenance port 5 to block it. After the maintenance port 5 is sealed, the electricity thief cannot steal the electricity from the electricity meter 4, which truly plays an anti-theft role. At the same time, the driving unit will push the second blocking portion away from the ventilation port 6. At this time, the ventilation port 6 is opened, and the ventilation port 6 replaces the observation window 7 to dissipate the heat in the installation chamber. When the driving unit receives the reset command, it will push the first blocking portion away from the maintenance port 5 to reopen it, and push the second blocking portion to the ventilation port 6 to re-block it. The control device includes a monitoring unit and an instruction sending unit 13. The monitoring unit can detect whether the maintenance door 2 is in the open state or the closed state, and transmit the monitoring information to the instruction sending unit 13. When the instruction sending unit 13 is closed, it can issue a closing command. The employee card recognition device includes an employee card reader area 9 and a control button area. The control button area includes a pause button 10 for pausing the instruction sending unit 13 and a reset button 11 that can send a reset instruction. When an employee places their employee card on the employee card reader area 9, their information is automatically recognized. If the employee is an employee of the power supply company, the control button area automatically activates. The activated pause button 10 and reset button 11 in the control button area function when pressed; otherwise, they have no effect. Pressing the pause button 10 pauses the instruction sending unit 13, preventing it from issuing a shutdown instruction. Pressing the reset button 11 issues a reset instruction. When the inspection door 2 turns from a closed state to an open state, the instruction sending unit 13 starts counting down, and sends a closing instruction after a few seconds, and no longer sends the closing instruction until the inspection door 2 turns from a closed state to an open state again and the instruction sending unit starts counting down again; when the pause button 10 is pressed before the instruction sending unit 13 sends the closing instruction, the instruction sending unit 13 no longer sends the closing instruction until the inspection door 2 turns from a closed state to an open state again and the instruction sending unit 13 starts counting down again.

[0034] The time period can be set to 5 to 10 seconds. This time period is based on the time it takes for an employee to place their employee card on the employee card recognition device. Of course, it is not limited to this time period and can be adjusted later based on long-term observation of employee operating habits. It is necessary to ensure that employees have sufficient time to identify their employee cards and that the electricity thief issues a shutdown command before putting his hands into the maintenance port 5.

[0035] Working principle:

[0036] (1) Reading the electricity: There is no need to open the inspection door 2. The electricity reading on the display screen of the electricity meter 4 behind the maintenance opening 5 can be observed through the observation window 7.

[0037] (2) When electricity theft occurs: At this time, whether the inspection door 2 is opened normally or the inspection door 2 is opened after the door lock 8 is manually damaged, the monitoring unit in the control device will detect that the inspection door 2 is in the open state and transmit this information to the instruction sending unit 13. A few seconds after receiving this information, the instruction sending unit 13 will issue a closing instruction. Then the driving part in the opening and closing device will push the first blocking part to the maintenance opening 5 to block it, hiding the electricity meter 4 in the installation chamber, and at the same time push the second blocking part away from the ventilation opening 6 to open the ventilation opening 6. Because the maintenance opening 5 is closed and the electricity meter 4 is hidden, the electricity thief cannot change the line of the electricity meter 4, which plays an anti-theft role.

[0038] (3) When performing maintenance:

[0039] ① During normal maintenance, after the staff opens the inspection door 2 normally with the key, the monitoring unit detects that the inspection door 2 is in the open state and transmits this information to the instruction sending unit 13. Before the instruction sending unit 13 issues a closing instruction, the staff needs to stick the employee card to the employee card reading area 9 of the employee card recognition device. After the reading is successful, the control button area will be automatically activated. At this time, just press the pause button 10, the instruction sending unit 13 will suspend work, and the maintenance port 5 will remain open. At this time, the staff can repair the electricity meter 4. When the inspection door 2 is closed and opened again, the instruction sending unit 13 will re-enter the working state.

[0040] ② When electricity theft occurs or the staff fails to affix the employee card in time, resulting in the maintenance port 5 being closed, the staff needs to affix the employee card to the employee card reading area 9 and then press the reset button 11. The reset button 11 will issue a reset command. After receiving the reset command, the driving unit will push the first blocking part away from the maintenance port 5 and push the second blocking part to the ventilation port 6 to prevent illegal personnel from damaging the electricity meter 4 and the like through the ventilation port 6.

[0041] Furthermore, in this embodiment, if Figures 1 to 8As shown, the monitoring unit includes a distance measuring sensor 12, which can monitor the distance between the inspection door 2 and the partition vertical plate 3, and determine whether the inspection door 2 is in a closed state or an open state.

[0042] In this embodiment, Figures 1 to 8 As shown, the distance measuring sensor 12 can be a laser distance measuring device or an ultrasonic distance measuring device, and the laser distance measuring device or the ultrasonic distance measuring device is fixed on the dividing vertical plate 3 .

[0043] In this embodiment, Figures 1 to 8 As shown, the driving part includes a ball screw and a driving motor 15. The ball screw includes a screw 16, an opening and closing nut pair 17, and a ventilation nut pair 18. The screw 16 is rotatably connected in the installation chamber. The axis of the screw 16 is arranged horizontally and parallel to the partition vertical plate 3. Preferably, one end of the screw 16 is rotatably connected to the side wall of the installation chamber through a bearing, and the other end of the screw 16 is rotatably connected to the hanger fixed on the top wall of the installation chamber through a bearing. The vent 6 and the screw 16 are on the same horizontal plane. The first blocking part includes a blocking baffle 19 fixed on the opening and closing nut pair 17. When the electric meter 4 has multiple rows, the blocking baffles 19 are also arranged in multiple rows accordingly. The blocking baffles 19 in the next row are connected to the blocking baffles 19 in the previous row through a connecting rod 21, and the blocking baffles 19 in the top row are connected to the opening and closing nut pair 17 through a connecting rod 21. The second blocking portion includes a blocking plug 20 that can be inserted into the vent 6 . The blocking plug 20 is fixed on the vent nut pair 18 and can be fixedly connected to the vent nut pair 18 via an L-shaped connector 22 .

[0044] In this embodiment, Figures 1 to 8 As shown, the anti-electricity theft system further includes an alarm 14 , which can remotely transmit an alarm signal to a monitoring room after receiving a shutdown signal, so as to notify staff that an electricity theft problem has occurred.

[0045] Furthermore, in this embodiment, if Figures 1 to 8 As shown, the alarm 14 is provided with an alarm horn that can send a warning sound, for deterring electricity thieves. The alarm horn can stop automatically after the access door 2 is closed, and can also stop automatically after pressing the pause button 10.

[0046] Furthermore, in this embodiment, if Figures 1 to 8 As shown, the monitoring room is equipped with an operating button that can remotely control the drive unit. Through the operating button, a shutdown command or reset command can be directly issued to the drive unit, eliminating the need to run to the scene to restore power after theft occurs. The operating button can also remotely control the alarm 14 to stop the alarm and the alarm horn to stop emitting warning sounds.

[0047] In this embodiment, Figures 1 to 8As shown, the height of the observation window 7 is consistent with the width of the reading display screen of the electricity meter 4. While ensuring the reading, it can also prevent electricity thieves from tampering with the electricity meter 4 through the observation window 7.

[0048] In order to further improve the protection of the observation window 7, in this embodiment, as Figures 1 to 8 As shown, transparent glass is provided on the observation window 7, and then, in order to ensure that the heat in the installation chamber can be effectively dissipated, a heat dissipation port communicating with the outside is provided on the inner wall of the maintenance chamber to replace the original observation window 7 without transparent glass to perform heat dissipation.

[0049] Furthermore, in this embodiment, the transparent glass is tempered glass, which can prevent criminals from smashing the tempered glass.

[0050] In this embodiment, Figures 1 to 8 As shown, the door lock 8 can optionally use a tongue lock. The lock tongue 23 of the tongue lock can be rotated 90 degrees from vertical to horizontal, and can be locked on the locking plate 24 of the maintenance chamber. By turning the lock tongue 23 from horizontal to vertical, the lock tongue 23 can be separated from the locking plate 24, completing the unlocking.

[0051] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
