Description

Technical Field

[0001] The present invention belongs to the technical field of electric energy meter connection boxes, and particularly relates to an anti-stealing electric energy meter connection box with remote control function. Background Art

[0002] The transparent cover of the currently used combined connection box for electric energy meters is fixed with two sealable screws, and anti-stealing electricity is carried out by adding seals. When replacing or inspecting the electric energy meter, the seals need to be removed, and new seals need to be added after the work. This not only has a cumbersome process and causes waste of seals, but also current electricity thieves buy fake seals from dealers to steal electricity, which cannot be effectively prevented and brings huge economic losses. Therefore, electric energy meter boxes with electronic intelligent locks have gradually attracted attention. For example, a safe anti-stealing electricity electric energy meter box disclosed in the patent document with publication number CN 105301309A and an anti-stealing electricity power metering box disclosed in the patent document with publication number CN 109142824A both use intelligent locks for safe anti-stealing electricity. However, the mechanical lock heads of traditional intelligent locks can only meet the locking on one side of the electric meter box, with poor protection effect and still having a high risk of electricity theft. Summary of the Invention

[0006] Further, the box cover includes a second bottom plate, a second frame plate and a second limiting plate. The second frame plate is fixedly arranged on the second bottom plate, and the second limiting plate is arranged inside the top surface of the second frame plate. The box cover is connected to the top edge of the connection box through two hinges.

[0007] Further, a plurality of through holes are correspondingly arranged on the first limiting plate and the second limiting plate.

[0008] Further, the mechanical lock head unit includes a convex rod mechanism arranged inside the first frame plate, a lock rod mechanism arranged inside the second frame plate, and a control mechanism for controlling the convex rod mechanism to pass through the through hole and controlling the lock rod mechanism to lock the passed convex rod mechanism.

One side of each first through hole is rotatably connected with a first gear, and a first screw hole is arranged at the center of each first gear. The first screw hole is the same size as and corresponds to the first through hole, and also corresponds to the position of the through hole. The first gears are all driven by the first motor; One end of the convex rod is provided with a thread, and the convex rod is threadedly connected with the first screw hole. One end of the convex rod is provided with a first limiting groove, and a first limiting strip is arranged in the first through hole, and the first limiting strip is located in the first limiting groove.

[0010] Further, the lock rod mechanism includes a second motor, a second cross bar, two second vertical bars, a plurality of second gears and a plurality of pressing rods. The second cross bar is arranged on the bottom plate of the second frame plate, and the two second vertical bars are respectively arranged on the two side plates of the second frame plate. A plurality of second through holes are arranged on the second cross bar and the two second vertical bars. One side of each second through hole is rotatably connected with a second gear, and a second screw hole is arranged at the center of each second gear. The second screw hole is the same size as and corresponds to the second through hole, and is located above the through hole. The second gears are all driven by the second motor; One end of the pressing rod is provided with a thread, and the pressing rod is threadedly connected with the second screw hole. One end of the pressing rod is provided with a second limiting groove, and a second limiting strip is arranged in the second through hole, and the second limiting strip is located in the first limiting groove.

[0011] Further, the control mechanism includes a microcontroller and a relay. The first motor and the second motor are both signal-connected to the microcontroller through the relay.

[0012] The meter box is a commonly used auxiliary device in the power system. Among them, in addition to having a protective function, the electricity meter box is more importantly used for wiring and power metering. Therefore, the electricity meter box is also a source of electricity theft. To improve the anti-theft electricity ability of the electricity meter box, what those skilled in the art easily think of is to set an electronic lock, an alarm device and a monitoring device on the electricity meter box. For example, a safe anti-theft electricity meter box disclosed in the patent document with publication number CN 105301309 A and an anti-theft electricity metering box disclosed in the patent document with publication number CN 109142824 A. The anti-theft electricity meter boxes disclosed in these two patent documents both use an electronic lock and an alarm for safety protection. The electronic lock is a common single mechanical lock head intelligent lock on the market. Cooperating with the monitoring and alarm system, it can meet a certain level of safety protection.

[0013] Based on the above situation, it is easy for those skilled in the art to think of respectively arranging a multi-lock structure inside the box body and the box cover of the electricity meter box. The reasons are as follows: First, as described above, the single-lock electronic lock supplemented with a monitoring and alarm system can achieve the function of safely preventing electricity theft of the electricity meter. Moreover, monitoring and alarm are commonly used devices in the power system and daily life, and their costs are relatively low. However, respectively arranging a multi-lock structure inside the box body and the box cover of the electricity meter box, specifically arranging a convex rod mechanism inside the box body and a lock rod mechanism inside the box cover, not only requires designing the mechanical structures of the convex rod mechanism and the lock rod mechanism, but also requires resetting the electricity meter junction box to meet the requirements of cooperating with the convex rod mechanism and the lock rod mechanism for unlocking and locking. Therefore, the cost will increase significantly. Moreover, the usage quantity of electricity meter boxes is huge, and the high cost is unacceptable to those skilled in this industry. Second, as the outer shell of the metering device, the function of the electricity meter box is essentially to provide protection and accommodate the electricity meter. If too many structures are designed in it, it will inevitably occupy the original wiring space of the electricity meter. If the volume of the electricity meter box is blindly increased, it will not only occupy a large amount of space, but also be inconvenient to install, and there will also be problems of resource waste. Therefore, those skilled in the art will not think of arranging a multi-lock fixing mechanism with a large volume inside the electricity meter box. Third, even if those skilled in the art think of arranging a multi-lock mechanism inside the electricity meter box, however, the multi-lock mechanism needs to meet many requirements such as small volume, not occupying the central area of the electricity meter box, multi-lock drive and mutual linkage. How to design the convex rod mechanism and the lock rod mechanism is a difficult problem to overcome for those skilled in the art. Fourth, the mechanical lock head of the traditional electronic lock is similar to an ordinary lock head. The only difference is that the key is replaced by a motor drive, and its mechanical lock head is still a telescopic structure. Therefore, when those skilled in the art think of a multi-lock structure, they will still adopt multiple telescopic lock heads, that is, the lock heads are arranged on the inner side of the box cover. When unlocking is required, the motor controls the lock heads to contract, and the box cover can be opened. When locking, first open and close the box cover, and then the motor controls the lock heads to extend, so that the lock heads enter the inner side of the box body to achieve fixation. This locking method is easy to implement and has a low technical threshold, and is more acceptable to those skilled in the art. Therefore, through the re-design of the electricity meter box body and the box cover, this application arranges a plurality of through holes at the docking place for a plurality of convex rods of the convex rod mechanism to enter the box cover from the box body, and then the lock rod mechanism on the inner side of the box cover fixes the plurality of convex rods one by one, thereby realizing the structural separation of the multi-lock, so that the two parts located inside the box body and the box cover are small in volume and do not occupy the main space. This technical solution is not easy for those skilled in the art to think of and implement.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The anti - electricity - theft wiring box for electric energy meters with remote control function provided by the present invention realizes functions such as remote authorization, unlocking / locking record, and technical encryption through an intelligent Internet - of - Things lock, optimizes the work process, improves work efficiency, and at the same time supports the anti - electricity - theft work, having the advantages of safety, convenience, simple operation, and improved anti - electricity - theft level;

[0016] 2. For the mechanical lock head unit of the wiring box, the box cover, and the intelligent Internet - of - Things lock of the present invention, the designed structures cooperate with each other, making the connection between the wiring box and the box cover more comprehensive and firm. After being locked, it cannot be easily pried open, with strong safety protection ability, ensuring the safe, stable, and economic operation of the power system;

[0017] 3. Both the wiring box and the box cover adopt the structure of a bottom plate, a frame plate, and a limiting plate. After they are docked, they have strong integrity, with a neat and beautiful appearance. Moreover, the mechanical lock head unit of the intelligent Internet - of - Things lock can be hidden in the groove formed by the frame plate and the limiting plate, without affecting the installation, disassembly, and observation of the electric energy meter;

[0018] 4. For the convex rod mechanism of the mechanical lock head unit, after receiving the instruction to lock the wiring box, the box cover is closed. The first motor drives a plurality of first gears to rotate, so that the convex rods among them pass through the through - holes on the first limiting plate and the second limiting plate and enter the cavity formed by the second limiting plate and the second frame plate. For the lock rod mechanism of the mechanical lock head unit, the second motor drives a plurality of second gears to rotate, so that the pressing rod moves horizontally from one side of the through - hole to the upper side of the convex rod and contacts the surface of the convex rod. Through the friction between the plurality of convex rods and the pressing rods, and the mutual cooperation between the convex rods and the pressing rods in the vertical direction on both sides and the horizontal direction at the bottom edge, the lock rod mechanism and the convex rod mechanism are kept locked, realizing the all - around connection and fixation of the wiring box and the box cover, greatly improving the safety protection ability of the electric energy meter wiring box.

[0019] 5. By redesigning the wiring box and the box cover, the present invention sets a multi - through - hole structure at the docking part of the wiring box and the box cover, sets a convex rod mechanism in the wiring box, and sets a lock rod mechanism in the box cover. The plurality of convex rods of the convex rod mechanism enter the box cover from the wiring box through the through - holes and are locked one by one by the lock rod mechanism, thus dividing the relatively large multi - lock - head structure into two parts, reducing the volume of the mechanism, not occupying the main space of the electric energy meter wiring box, and not increasing the volume of the wiring box, nor increasing the installation and wiring difficulty, improving the market acceptability of the wiring box of the present invention, and having good application and promotion prospects.

[0032] Operation steps of the electricity meter anti-stealing wiring box with remote control function in the embodiment of the present invention:

[0034] (2) After the backstage staff receive the information and approve it, they authorize unlocking;

[0035] (3) The mobile phone transmits the unlocking information to the electronic key, and the electronic key is used to open the Internet of Things lock;

[0036] (4) Remove the transparent cover of the combined junction box for operation, and cover the transparent cover of the combined junction box after the work is completed;

[0038] Specific unlocking steps:

[0039] 1. When the microcontroller of the control mechanism receives the unlocking command, first start the second motor through the relay to drive a plurality of second gears to rotate.

[0042] The locking steps are opposite to the unlocking steps, specifically as follows:

[0043] 1. When the microcontroller of the control mechanism receives the locking command, start the first motor to rotate in the reverse direction through the relay. Driven by the first gears and under the limiting action of the first limiting groove and the first limiting strip, the convex rod moves relative to the first gears, passing through the through holes of the first limiting plate and the second limiting plate and entering the inside of the box cover;

[0044] 2. Then the control mechanism starts the second motor to rotate in the reverse direction through the relay. Driven by the second gears and under the action of the second limiting groove and the second limiting strip, the pressing rod moves relative to the second gears, translating from the inner side of the box cover to the upper side of the convex rod to realize the pressing on the convex rod;

[0045] 3. Locking is completed.
