Description

Technical Field

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

[0002] An electric energy metering device is a metering instrument used to measure and record power generation, power supply (mutual supply), plant power consumption, line loss and user power consumption. An electric energy metering device refers to a system consisting of an electric energy meter (active energy meter, reactive energy meter, maximum demand meter, multi-rate energy meter, etc.), a metering transformer (including voltage transformer and current transformer) and secondary connecting wires. The electric energy meter is the core component of the electric energy metering device and is an instrument that measures the cumulative value of electric energy over a certain period of time. The electric energy meter is a special metering instrument for recording electric energy. It was born with the emergence of power supply companies and has continued to improve with the development of power supply companies. It is one of the largest measuring instruments owned by society and is mainly used for electricity trade settlement and assessment of technical and economic indicators of power production.

[0003] Currently, existing electricity meters present numerous practical challenges. For one thing, traditional meters are installed at a fixed height, making it difficult to flexibly adjust to suit different usage scenarios and the operator's needs. When meters are installed too high, operators require the use of ladders and other tools for data reading, inspection, and maintenance, which is not only inconvenient but also poses a safety hazard. Meters installed too low are susceptible to collisions and damage, impacting the meter's normal operation and lifespan.

[0004] On the other hand, when inspecting and maintaining electricity meters, workers often need to carry a large number of inspection tools. During operation, the placement and access of tools is inconvenient, and tools can easily be lost or left inside the electricity meter, hindering the smooth progress of the inspection. Furthermore, existing electricity meters have certain limitations in their anti-theft functions, making it difficult to effectively prevent various thefts, resulting in economic losses for power companies. Summary of the Invention

[0005] Purpose of the invention: The present invention aims to provide an anti-theft electricity meter that effectively prevents the occurrence of electricity theft by adopting a variety of anti-theft technical means, thereby ensuring the accuracy and reliability of electricity metering.

[0006] Technical solution: An anti-electricity theft electricity meter, comprising a guide rail, an inner side of which is integrally formed with a T-shaped slide, a top of the guide rail being fixedly connected to a drive motor, a reciprocating screw being fixedly connected to the bottom end of the drive motor output shaft and located inside the guide rail; a screw sleeve being threadedly connected to the outer side wall of the reciprocating screw, the screw sleeve being slidably connected to the T-shaped slide, a power box being fixed to the front surface of the screw sleeve, a power metering device being installed inside the power box, a tool box being arranged below the power metering device, and a box cover being rotatably connected to the left side of the front surface of the power box via a hinge.

[0007] Furthermore, a fixing plate is fixedly installed above the rear surface of the guide rail, and screws are provided at the four corners of the fixing plate.

[0008] Furthermore, a box lock is installed on the right side of the box cover, and a lock buckle is fixedly installed on the right side of the front surface of the power box.

[0009] Furthermore, a fixed block is installed at the bottom of the toolbox, the inner side of the fixed block is slidably connected to a sliding rod, the front end of the sliding rod is fixedly connected to the mounting block, the bottom of the mounting block is fixedly connected to the inner lower surface of the power box, the rear end of the sliding rod is fixedly connected to the inner rear surface of the power box, and a spring is fixedly connected between the fixed block and the mounting block and located on the outer side of the sliding rod.

[0010] Furthermore, movable sliders are fixedly connected to both sides of the screw sleeve, and the movable sliders are slidably connected to the T-shaped slideway.

[0011] Furthermore, ventilation holes are provided on both sides of the power box.

[0012] Furthermore, anti-slip blocks are fixedly connected to the upper and lower parts of the T-shaped slideway.

[0013] Beneficial effects: This power box device innovatively integrates intelligent remote control height adjustment and automatic pop-up tool box design to achieve functional coordination and safety upgrades: the reciprocating screw linkage structure driven by remote control can accurately adjust the height of the power box to avoid the risks of manual climbing operations; the screw sleeve and the T-shaped slide cooperate with the moving slider to ensure that the lifting process is stable and anti-derailment, ensuring personnel safety and equipment life. At the same time, when inspecting, opening the box cover can trigger the linkage between the bottom slide and the installation block, so that the built-in tool box automatically pops out and special tools for the power metering device are quickly accessed; when closing, press the fixing block to achieve a secure lock to prevent the loss of tools. This integrated design not only solves the problems of inconvenient installation and operation of traditional devices and chaotic tool management, but also optimizes space utilization through functional integration, significantly improves maintenance efficiency and safety, and provides an efficient and convenient comprehensive solution for power operation and maintenance.

[0014] The height adjustment of the power box requires the use of a remote control device, which moves up and down through the screw sleeve fixed on the rear surface of the power box and the reciprocating screw in the guide rail. The left and right surfaces of the screw sleeve are connected to movable sliders to further enhance its stability during the operation of the T-type slide. In the working state, it prevents the power box from derailing due to frequent operation of the staff, ensures the personal safety of the staff, and extends the life of the device.

[0015] When the tool box lid is open, it can be automatically popped out through the sliding rod and mounting block at the bottom of the tool box. When the tool box is closed, it needs to be pressed inward so that the fixing block at the bottom of the tool box is attached to the sliding rod. Maintenance tools for the power metering device are placed in the tool box to prevent maintenance personnel from forgetting or taking them by mistake, thereby increasing practicality.

[0024] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figure 1-Figure 7As shown, an anti-electricity theft power meter is provided, which includes a guide rail 1, a T-shaped slide 2 integrally formed on the inner side of the guide rail 1, a drive motor 3 fixedly connected to the top of the guide rail 1, a reciprocating screw 4 fixedly connected to the bottom end of the output shaft of the drive motor 3 and located inside the guide rail 1; a screw sleeve 5 is threadedly connected to the outer wall of the reciprocating screw 4, and the screw sleeve 5 is slidably connected to the T-shaped slide 2, a power box 6 is fixed to the front surface of the screw sleeve 5, an electricity metering device 7 is installed inside the power box 6, a tool box 8 is provided below the electricity metering device 7, and a box cover 10 is rotatably connected to the left side of the front surface of the power box 6 via a hinge;

[0027] like Figure 7 As shown, a fixed block 9 is installed at the bottom of the tool box 8, a slide rod 15 is slidably connected to the inner side of the fixed block 9, a mounting block 16 is fixedly connected to the front end of the slide rod 15, the bottom of the mounting block 16 is fixedly connected to the inner lower surface of the power box 6, and the rear end of the slide rod 15 is fixedly connected to the inner rear surface of the power box 6. A spring 20 is fixedly connected between the fixed block 9 and the mounting block 16 and located on the outer side of the slide rod 15.

[0028] The height adjustment of the power box 6 requires the help of a remote control device, which moves up and down through the screw sleeve 5 fixed on the rear surface of the power box 6 and the reciprocating screw 4 in the guide rail 1. The movable sliders 17 are connected to the left and right surfaces of the screw sleeve 5 to further enhance the stability during the operation of the T-shaped slide 2. In the working state, it prevents the power box 6 from derailing due to frequent operation of the staff, thereby ensuring the personal safety of the staff and extending the life of the device.

[0029] like Figure 6 and Figure 7 As shown, when the tool box lid 10 is in the open state, the tool box 8 can be automatically popped out through the slide bar 15 and the mounting block 16 at the bottom of the tool box 8. When the tool box 8 is in the closed state, it needs to be pressed inward so that the fixing block 9 at the bottom of the tool box 8 is in contact with the slide bar 15. The maintenance tools of the power metering device 7 are placed in the tool box 8 to prevent maintenance personnel from forgetting or taking them by mistake, thereby increasing practicality.

[0030] like Figure 3 As shown, a fixing plate 12 is fixedly installed above the rear surface of the guide rail 1, and screws 13 are provided at the four corners of the fixing plate 12;

[0031] The fixing plate 12 is installed above the rear surface of the guide rail 1 and is connected to the wall, bracket and other installation carriers through screws 13 at the four corners. It can not only evenly disperse the forces generated by operations such as lifting and lowering the power box 6 and taking tools in a multi-point fixing manner to ensure the stable installation of the guide rail 1, but also facilitate calibration and adjustment during installation and subsequent disassembly and maintenance; at the same time, it cooperates with the screws 13 to enhance the rigidity of the guide rail 1, suppress the deformation and shaking of the power box 6 during operation, and reduce component wear. In addition, according to the characteristics of different installation carriers such as concrete, metal, and wood, screws 13 of appropriate specifications can be selected to achieve a firm connection, which significantly improves the installation convenience, structural stability and scene adaptability of the device.

[0032] like Figure 2 As shown, a box lock 11 is installed on the right side of the box cover 10, and a lock buckle 14 is fixedly installed on the right side of the front surface of the power box 6;

[0033] The lock 11 mounted on the right side of the cover 10 and the latch 14 fixed to the right front surface of the power box 6 cooperate to form a reliable locking system. This design, through mechanical locking, tightly secures the cover 10 to the power box 6, effectively preventing accidental opening of the cover 10 by external force, thus exposing the internal power metering device 7 and tool box 8, and reducing the risk of dust and moisture intrusion, component theft, and vandalism. Furthermore, it standardizes equipment operation procedures, ensuring that only authorized personnel can open the lock 11 with a key, ensuring the safety and standardization of power equipment operation and maintenance, and guaranteeing the accuracy of power metering data and the orderly access to maintenance tools.

[0034] like Figure 4 and Figure 5 As shown, both sides of the screw sleeve 5 are fixedly connected with movable sliders 17, and the movable sliders 17 are slidably connected to the T-shaped slideway 2;

[0035] The movable sliders 17 fixedly connected on both sides of the screw sleeve 5 slide in conjunction with the T-shaped slide 2 to form a precise guide and stable support structure. During the lifting process of the power box 6, the movable slider 17 slides smoothly along the T-shaped slide 2, which can effectively limit the deviation and shaking of the screw sleeve 5, and disperse the lateral force and vibration generated by the operation of the power box 6 to the guide rail 1, ensuring that the screw sleeve 5 drives the power box 6 to move accurately in the vertical direction. This design not only significantly improves the stability of the power box 6 during lifting and lowering, prevents the risk of derailment, and ensures the safety of personnel operation, but also extends the service life of core components such as the screw sleeve 5 and the guide rail 1 by reducing abnormal friction between components, thereby enhancing the reliability and durability of the entire device.

[0036] like Figure 3 As shown, ventilation holes 18 are provided on both sides of the power box 6;

[0037] By creating an air convection channel, the heat dissipation problem during equipment operation is effectively solved. When internal components such as the power metering device 7 continue to operate and generate heat, the vents 18 accelerate air exchange between the inside and outside of the box, preventing heat accumulation from overheating the components. This reduces the probability of equipment failure caused by high temperatures and ensures the accuracy and stability of power metering data.

[0038] like Figure 5 As shown, anti-slip blocks 19 are fixedly connected to the upper and lower parts of the T-shaped slideway 2;

[0039] It constitutes a double protection mechanism, building a solid safety line for the operation of the power box 6. When the screw sleeve 5 drives the power box 6 to rise and fall along the T-shaped slide 2, the anti-slip block 19 can effectively prevent the moving slider 17 from accidentally leaving the slide. Even in extreme cases (such as component wear, external force impact), it can prevent the power box 6 from derailing and falling, greatly reducing the probability of safety accidents. At the same time, this design further enhances the structural stability of the entire lifting system, limits the abnormal displacement of the slider in the slide, ensures the smooth operation of the power box, reduces component loss caused by shaking, and significantly improves the safety and service life of the equipment.

[0040] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
