Description

Technical Field

[0001] This invention relates to the field of low-voltage power distribution equipment technology, specifically to an anti-theft multi-functional power metering box. Background Technology

[0002] With the continuous advancement of the smart grid industry and the ongoing upgrading of power electronic component manufacturing technology, electricity metering boxes, as core enclosure equipment carrying metering elements in low-voltage power distribution systems, have become an important component at the end of the power distribution network. Existing electricity metering boxes mainly consist of a enclosure, door, internal mounting frame, and wiring components. The enclosure houses electricity metering instruments and matching terminals, and the orderly connection between external cables and internal metering circuits is achieved through inlet and outlet conduits. Some advanced products add remote control modules and status monitoring components inside the box to meet the intelligent needs of power distribution operation and maintenance. These metering boxes rely on a closed shell to provide basic protection for internal components, meeting the needs of electricity metering and power distribution management under normal operating conditions, and are widely used in residential transformer substations and industrial and commercial power distribution scenarios.

[0003] Existing power metering boxes primarily focus on the door locks and overall casing strength, lacking active protection and interlocking anti-theft mechanisms for the incoming line wiring. Electricity thieves can easily steal electricity by illegally disconnecting incoming cables or altering internal wiring circuits, making such theft difficult to detect promptly. Current alarm detection mechanisms are mostly independent electrical monitoring modules, not linked to the incoming line mechanical structure. This leads to false alarms and difficulty in simultaneously creating a physical barrier against illegal disconnection. The overall anti-theft protection lacks sufficient integrity and reliability, failing to meet the refined electricity inspection needs of the smart grid industry and hindering the optimization and upgrading of power electronic component manufacturing towards integrated interlocking protection. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-theft multifunctional power metering box to solve the problems mentioned in the background art, such as the lack of active protection and interlocking anti-theft mechanisms on the incoming line side of existing power metering boxes. Electricity thieves can illegally disconnect the incoming line and modify the internal wiring circuit to steal electricity, and the theft is difficult to detect in time. Existing alarm detection is mostly an independent electrical module, which is not linked with the incoming line mechanical structure, is prone to false alarms, and cannot simultaneously form physical locking. It is difficult to adapt to the problems of refined inspection and integrated upgrading of power electronic component manufacturing in the smart grid industry.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a theft-proof multi-functional electricity metering box, comprising a box body, a door rotatably mounted on one side of the box body, and a fixing frame fixed to the bottom of the box body. A meter mounting frame is fixed inside the box body, and several meters are mounted on one side of the meter mounting frame. A mounting box is fixed to the outside of the meter mounting frame near the bottom of each meter. An inlet junction box is fixed to the outside of the mounting box near each wiring hole at the bottom of the meter. An anti-theft locking component is installed inside the inlet junction box, and an opening / closing triggering component is installed inside the mounting box. One end of the inlet junction box is connected to and fixed with a conduit, and the other end is connected to and fixed with a connecting pipe. One end of the connecting pipe is inserted into the corresponding wiring hole at the bottom of the meter, and an alarm triggering component is installed outside the connecting pipe.

[0006] Furthermore, the opening and closing triggering component includes a limiting slide, a limiting slider, and an electric telescopic rod. The limiting slide is fixedly installed inside the mounting box, the limiting slider is slidably sleeved on the outside of the limiting slide, the electric telescopic rod is disposed outside one end of the limiting slider, a positioning frame is fixed inside one end of the mounting box, the electric telescopic rod is fixedly installed outside the positioning frame, and the output end of the electric telescopic rod is fixedly connected to one end of the limiting slider.

[0007] Furthermore, an intelligent remote control module is fixed on one side of the positioning frame. The intelligent remote control module is electrically connected to the electric telescopic rod and is used to control the telescopic movement of the electric telescopic rod. A through hole is provided between the mounting box and the inlet junction box. An arched abutment block is fixedly installed on one end of the limiting slider near the through hole. An abutment roller is abutted against the side of the arched abutment block away from the positioning frame.

[0008] Furthermore, the anti-theft locking assembly includes a semi-circular abutment block and an abutment frame. The semi-circular abutment block is disposed in the middle of the inlet junction box, the abutment frame is fixedly installed in the middle of the bottom end of the semi-circular abutment block, and the abutment roller is inserted and engaged through the bottom end of the abutment frame.

[0009] Furthermore, two auxiliary frames are symmetrically arranged on both sides of the bottom end of the semicircular contact block. The bottom end of each auxiliary frame is fixedly installed on the bottom wall of the mounting box. A limit rod is vertically and slidably installed inside each auxiliary frame. The top end of the limit rod is fixedly connected to the bottom end of the semicircular contact block.

[0010] Furthermore, a limit stop is fixedly connected to the bottom end of the limit rod, and a tension spring is sleeved on the outside of the limit rod. The two ends of the tension spring are respectively fixedly installed on the top wall of the auxiliary frame and the bottom wall of the semi-circular contact block.

[0011] Furthermore, a stop rod is fixedly installed at the end of the limiting slider away from the electric telescopic rod, a trigger micro switch module is fixedly installed on the inner wall of the mounting box near the stop rod, and a power failure alarm is fixedly installed on the outside of one side of the mounting box by a bracket, and a control conductive connection line is electrically connected between the power failure alarm and the trigger micro switch module.

[0012] Furthermore, several support frames are fixed to the outside of the mounting box, and a coated conductive copper rod is fixedly installed between the tops of the several support frames. One end of the coated conductive copper rod is electrically connected to the trigger micro switch module by a first conductive connection line, and the other end of the coated conductive copper rod is electrically connected to the power failure alarm by a second conductive connection line.

[0013] Furthermore, the alarm triggering component includes an auxiliary hole, a contact port, and a conductive copper block. The auxiliary hole is opened through the top of the connector tube, the contact port is opened through the side of the coated conductive copper rod near the auxiliary hole, and the conductive copper block is fitted and conductively disposed between the contact ports of the coated conductive copper rod. An arc-shaped extrusion insulating block is vertically slidably disposed inside the auxiliary hole.

[0014] Furthermore, a positioning block is fixed to the outside of the incoming line junction box near the side of the arc-shaped extruded insulating block. The top end of the arc-shaped extruded insulating block is slidably installed outside the top end of the positioning block. The bottom end of the conductive copper block is fixedly installed outside the top end of the arc-shaped extruded insulating block. Guide rods are vertically slidably installed inside both sides of the positioning block. The top end of the guide rod is fixedly connected to the top side of the arc-shaped extruded insulating block. A return spring is sleeved on the outside of the guide rod. The two ends of the return spring are respectively fixedly installed on the top side of the arc-shaped extruded insulating block and the top wall of the positioning block.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention relies on mature technology in the manufacture of power electronic components. An intelligent remote control module drives an electric telescopic rod to smoothly move a limit slider along a limit carriage. Through the inclined transmission action of the arched contact block and the contact roller, the semi-circular contact block is pushed vertically upward along the limit rod guide. This compresses and bends the cables passing through conduits, inlet junction boxes, and connectors, enhancing the anti-loosening effect of the wiring, increasing the resistance to cable extraction, and simultaneously compressing the available space for cable threading within the conduit, thus improving the anti-theft capability on the inlet side. The entire mechanism shares the same drive source, eliminating the need for an independent protection module. This improves the integration and reliability of the distribution box's protective structure, making it well-suited to the refined power management needs of the smart grid industry.

[0016] This invention relies on the stable manufacturing process of power electronic components. The alarm triggering component and the on / off triggering component form an electromechanical linkage system. The arc-shaped extruded insulating block drives the contact port of the conductive copper block and the rubber-coated conductive copper rod to form the incoming line in-situ detection circuit. With the help of the triggering micro switch module, the alarm circuit is shielded under legal operation and maintenance conditions. When electricity is stolen by force, the detection circuit is broken, which triggers the power failure alarm on site and simultaneously uploads it to the remote end. The structure of independent configuration of each meter position makes it easy for operation and maintenance personnel to quickly locate abnormal meters, improve the efficiency of handling electricity inspections, and further improve the interlocking protection system on the incoming line side of the distribution box. It can effectively adapt to the electricity safety management and control needs under the smart grid industry. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 10 An anti-theft multi-functional electricity metering box includes a box body 1, a door 2 rotatably mounted on one side of the box body 1, and a fixing frame 3 fixed to the bottom of the box body 1. A meter mounting frame 4 is fixed inside the box body 1, and several meters 5 are mounted on one side of the meter mounting frame 4. A mounting box 6 is fixed to the outside of the meter mounting frame 4 near the bottom of each meter 5. An inlet junction box 7 is fixed to the outside of the mounting box 6 near each wiring hole at the bottom of the meter 5. An anti-theft locking component is provided inside the inlet junction box 7, and an opening and closing triggering component is provided inside the mounting box 6. One end of the inlet junction box 7 is connected to and fixed with a conduit 8, and the other end of the inlet junction box 7 is connected to and fixed with a connecting pipe 9. One end of the connecting pipe 9 is inserted into the corresponding wiring hole at the bottom of the meter 5.

[0021] The opening and closing triggering assembly includes a limiting slide 10, a limiting slider 11, and an electric telescopic rod 13. The limiting slide 10 is fixedly installed inside the mounting box 6. The limiting slider 11 is slidably sleeved on the outside of the limiting slide 10. The electric telescopic rod 13 is located outside one end of the limiting slider 11. A positioning frame 12 is fixed inside one end of the mounting box 6. The electric telescopic rod 13 is fixedly installed outside the positioning frame 12. The output end of the electric telescopic rod 13 is fixedly connected to one end of the limiting slider 11.

[0022] A smart remote control module 14 is fixed on one side of the positioning frame 12. The smart remote control module 14 is electrically connected to the electric telescopic rod 13 and is used to control the telescopic movement of the electric telescopic rod 13. A through hole 16 is provided between the mounting box 6 and the inlet junction box 7. An arched abutment block 15 is fixedly installed on one end of the limiting slider 11 near the through hole 16. An abutment roller 17 is abutted and attached to the side of the arched abutment block 15 away from the positioning frame 12.

[0023] The anti-theft locking assembly includes a semi-circular abutment block 18 and an abutment frame 19. The semi-circular abutment block 18 is located in the middle of the inlet junction box 7, and the abutment frame 19 is fixedly installed in the middle of the bottom end of the semi-circular abutment block 18. The abutment roller 17 is inserted through and rotated to engage with the outside of the bottom end of the abutment frame 19.

[0024] Two auxiliary frames 20 are symmetrically arranged on both sides of the bottom end of the semicircular contact block 18. The bottom end of each auxiliary frame 20 is fixedly installed on the bottom wall of the mounting box 6. A limit rod 21 is vertically slidably installed inside each auxiliary frame 20. The top end of the limit rod 21 is fixedly connected to the bottom end of the semicircular contact block 18.

[0025] The bottom end of the limiting rod 21 is fixedly connected to the limiting block 23, and the outside of the limiting rod 21 is fitted with a tension spring 22. The two ends of the tension spring 22 are respectively fixedly installed on the top wall of the auxiliary frame 20 and the bottom wall of the semi-circular contact block 18.

[0026] In this embodiment, when the device is installed as a whole, the box 1 is installed by the bottom fixing frame 3. After the box door 2 is rotated and closed, it can form a basic closed protection for the internal components of the box 1. The meter mounting frame 4 provides a stable installation reference for the internal measuring elements and supporting protective components. During the wiring process of meter 5, the external cable passes through conduit 8, inlet junction box 7 and connector 9 in sequence and is connected to the corresponding wiring hole at the bottom of meter 5. The mounting box 6 and inlet junction box 7 provide a sealed installation space for the entire interlocking protection components.

[0027] After the wiring work is completed, the operator can send control commands to the intelligent remote control module 14 through a mobile terminal or remote control device. Relying on the mature technology of power electronic component manufacturing, the intelligent remote control module 14 outputs a stable control signal to drive the electric telescopic rod 13 to perform the extension action. Under the fixed support of the positioning frame 12, the electric telescopic rod 13 pushes the limit slider 11 to slide smoothly along the axis of the limit slide 10, and simultaneously drives the arched contact block 15 to move towards the side of the inlet junction box 7. The arched contact block 15 passes through the through hole 16 opened between the mounting box 6 and the inlet junction box 7, and its outer arc surface gradually contacts and fits against the contact roller 17. Under the inclined transmission action of the arched contact block 15, the contact roller 17 drives the contact frame 19 and the semi-circular contact block 18 to rise synchronously. During the lifting process, the limiting rod 21 slides vertically along the guide hole of the auxiliary frame 20, forming a stable guide for the movement direction of the semi-circular contact block 18 and avoiding lateral deviation. The tension spring 22 is stretched and stored accordingly. The limiting stop 23 at the bottom of the limiting rod 21 can limit the maximum stroke of the lifting and prevent the component from exceeding the range of motion and causing jamming or disengagement.

[0028] After the semi-circular contact block 18 is raised to the set position, its top arc surface abuts against the middle of the cable passing through the conduit 8, the inlet junction box 7, and the connector 9, forming a certain degree of compression and bending on the cable, increasing the frictional resistance between the cable and the inner wall of the conduit, which can reduce the probability of the cable loosening due to external pulling force or environmental vibration, and play the role of preventing loosening of the connection. At the same time, it also increases the difficulty for electricity thieves to directly pull out the cable to carry out rewiring operations.

[0029] Meanwhile, the raised semi-circular contact block 18 forms a staggered shield with the conduit ports of conduit 8 and connecting pipe 9, blocking the lateral wiring space between the two conduit sections. This can, to a certain extent, curb electricity theft by inserting additional wires from the conduit 8 side and bypassing the meter 5 to form a parallel circuit, thus strengthening the physical anti-theft barrier on the incoming line side. This mechanical interlocking protection structure based on the incoming line side can be adapted to the refined electricity management needs of the smart grid industry. Through the coordinated cooperation of electric control drive and mechanical transmission, it achieves multiple functions such as wiring loosening prevention and incoming line theft prevention under the same set of actuators, without the need for additional independent protection modules. This improves the overall integrity and reliability of the meter box protection structure and provides a feasible structural approach for the protection upgrade of distribution box equipment.

[0030] Example 2: Please refer to Figure 4 - Figure 12 This embodiment further illustrates Example 1, and an alarm triggering component is provided on the outside of the control pipe 9.

[0031] A stop rod 25 is fixedly installed at the end of the limit slider 11 away from the electric telescopic rod 13. A trigger micro switch module 24 is fixedly installed on the inner wall of the mounting box 6 near the stop rod 25. A power failure alarm 31 is fixedly installed on the outside of one side of the mounting box 6 by a bracket. A control conductive connection line 26 is electrically connected between the power failure alarm 31 and the trigger micro switch module 24.

[0032] The mounting box 6 is externally fixed with several support frames 28. A rubber-coated conductive copper rod 29 is fixedly installed between the tops of the support frames 28. One end of the rubber-coated conductive copper rod 29 is electrically connected to the trigger micro switch module 24 by a first conductive connection line 27, and the other end of the rubber-coated conductive copper rod 29 is electrically connected to the power failure alarm 31 by a second conductive connection line 30.

[0033] The alarm triggering component includes an auxiliary hole 32, a contact port 33, and a conductive copper block 34. The auxiliary hole 32 is opened through the top of the connector 9. The contact port 33 is opened through the side of the coated conductive copper rod 29 near the auxiliary hole 32. The conductive copper block 34 is fitted and conductively disposed between the contact ports 33 opened on the coated conductive copper rod 29. An arc-shaped extrusion insulating block 36 is vertically slidably disposed inside the auxiliary hole 32.

[0034] A positioning block 35 is fixed to the outside of the incoming line junction box 7 near the side of the arc-shaped extruded insulating block 36. The top of the arc-shaped extruded insulating block 36 is slidably installed on the outside of the top of the positioning block 35. The bottom of the conductive copper block 34 is fixedly installed on the outside of the top of the arc-shaped extruded insulating block 36. Guide rods 37 are vertically slidably installed inside both sides of the positioning block 35. The top of the guide rod 37 is fixedly connected to the top side of the arc-shaped extruded insulating block 36. A return spring 38 is sleeved on the outside of the guide rod 37. The two ends of the return spring 38 are fixedly installed on the top side of the arc-shaped extruded insulating block 36 and the top wall of the positioning block 35, respectively.

[0035] In this embodiment, based on the mechanical locking protection on the incoming line side in Embodiment 1, the metering box is equipped with a trigger alarm component that is linked to the opening and closing trigger component. Relying on the mature manufacturing process of power electronic components, the stability of conductive contact is ensured, and an integrated electromechanical protection system for the incoming line is constructed, which is further adapted to the power safety management and control requirements under the smart grid industry.

[0036] When the wiring is completed and the electric telescopic rod 13 is in the extended warning state, the limit slider 11 moves horizontally along the limit slide 10 to the front end position. The abutment rod 25 fixed to the end of the limit slider 11 moves forward synchronously, pressing the trigger micro switch module 24 on the inner wall of the mounting box 6, so that the alarm control circuit is in the conducting and enabled state. The control conductive connection line 26 realizes the control signal transmission between the trigger micro switch module 24 and the power failure alarm 31. The first conductive connection line 27 and the second conductive connection line 30 respectively connect the two ends of the rubber-coated conductive copper rod 29 to the detection circuit. The support frame 28 provides stable installation support for the rubber-coated conductive copper rod 29, ensuring the relative position accuracy of the conductive components.

[0037] At this time, the cable passing through the inside of the connector 9 abuts against the bottom arc surface of the arc-shaped extrusion insulating block 36 from the auxiliary hole 32, pushing the arc-shaped extrusion insulating block 36 to slide upward along the guide of the positioning block 35. The guide rod 37 moves vertically upward along the corresponding hole of the positioning block 35, and the reset spring 38 is stretched and stored. The conductive copper block 34 fixed at the top of the arc-shaped extrusion insulating block 36 is raised simultaneously and embedded in the contact port 33 opened on the side wall of the rubber-coated conductive copper rod 29, forming a stable contact and conduction with the rubber-coated conductive copper rods 29 on both sides, so that the detection circuit of the power failure alarm 31 remains in a closed state, and the power failure alarm 31 is in a normal monitoring standby state and does not trigger an alarm.

[0038] When electricity thieves forcibly pull the cable to steal electricity, the incoming cable in the connector 9 is pulled outward by external force. The upward force of the cable against the arc-shaped extrusion insulation block 36 gradually disappears. Under the elastic reset force of the reset spring 38, the arc-shaped extrusion insulation block 36 slides vertically downward along the auxiliary hole 32 to reset, causing the conductive copper block 34 to move down and separate from the contact port 33. This causes the detection circuit formed by the rubber-coated conductive copper rod 29 to change from a conductive state to a disconnected state. At this time, the micro switch module 24 is still in the pressed-on enabled state. After the power failure alarm 31 detects the power failure of the circuit, it immediately triggers the on-site audible and visual alarm to alert the surrounding personnel that there is an abnormal wiring operation. At the same time, the intelligent remote control module 14 is linked to upload the alarm event to the existing remote monitoring platform in a timely manner to remind the maintenance personnel to rush to the site for verification and handling.

[0039] Since each meter 5 is equipped with an independent mounting box 6 and a matching alarm triggering component at the bottom, the alarm signal can be accurately matched to a specific meter 5, which makes it easy for maintenance personnel to quickly locate meters with electricity theft risks, reduce on-site investigation time, and improve the efficiency of electricity inspection.

[0040] When maintenance personnel carry out legitimate maintenance work, they can send an unlocking command to the intelligent remote control module 14 through the remote control device to drive the electric telescopic rod 13 to retract. The electric telescopic rod 13 drives the limit slider 11 to move backward along the limit slide 10. On the one hand, it drives the arched abutment block 15 to move backward synchronously, so that the semi-circular abutment block 18 descends under the reset action of the tension spring 22, releasing the compression lock on the cable, making it easy for maintenance personnel to smoothly pull out the cable for maintenance. On the other hand, the abutment rod 25 fixed to the end of the limit slider 11 moves backward synchronously, disengaging from the pressing contact with the trigger micro switch module 24, so that the alarm control circuit turns to the disconnected state. At this time, when the maintenance personnel pull out the incoming cable and the detection circuit is disconnected, the power failure alarm 31 will not trigger an alarm, realizing the alarm function shielding in the maintenance state, avoiding false alarms caused by normal maintenance operations, and improving the convenience of on-site operations.

[0041] This set of trigger alarm components and mechanical locking components share the same electronic control drive source. Through a single actuator, it synchronously achieves the dual actions of physical locking of the incoming line and enabling of the alarm circuit. There is no need to configure additional independent drive and control modules, which improves the integration and integrity of the internal protection structure of the enclosure 1. It not only conforms to the technical direction of power electronic component manufacturing towards integrated interlocking protection, but also better adapts to the refined and differentiated power safety management needs under the smart grid industry. It provides a compact and reliable solution for the anti-theft protection upgrade of low-voltage distribution metering boxes.
