Description

Technical Field

[0001] This utility model relates to the field of rail-mounted energy meters, and in particular to a mobile energy meter with a rail structure. Background Technology

[0002] With rapid economic development, the demand for electricity from all sectors is increasing, and the shortage of electricity resources and the uneven distribution of electricity consumption at different times remain serious problems. To alleviate the increasingly acute contradiction between electricity supply and demand in my country, improve the imbalance in electricity consumption, promote energy conservation, and enhance national electricity efficiency, the rational utilization of electricity resources has become one of the basic national policies. A large amount of electricity consumption is concentrated in low-voltage distribution terminals. To strengthen the metering, assessment, and management of terminal electricity consumption and facilitate on-site use, renovation, and upgrading for users, a miniaturized DIN rail-mounted electricity meter has been designed to address the inconvenience of installing traditional DDSD and DTSD series wall-mounted electricity meters in the field. This meter features high measurement accuracy, strong overload capacity, stable and reliable performance, a wide operating voltage range, and low power consumption. Furthermore, its small size, light weight, and modular structure allow it to be used in conjunction with miniature circuit breakers and installed in distribution boxes to achieve terminal distribution electricity metering.

[0003] Most existing DIN rail-mounted energy meters have fixed, non-adjustable bottom rails. This can lead to situations where the rails are too large or too small when installing on different user sites, making installation cumbersome and time-consuming for workers. Furthermore, since traditional DIN rail-mounted energy meters are directly mounted on the rail, when multiple meters are mounted on the same rail, the meter in the middle is inconvenient to remove for maintenance or replacement. It requires removing the other meters on one side one by one before the meter in question can be removed. To address these technical problems, this application proposes a track-mounted mobile energy meter. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology by proposing a track-structured mobile energy meter. This mobile energy meter can be installed on rails of various specifications, and it can be removed for maintenance without disassembling other energy meters, making it convenient to use and install.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mobile energy meter with a track structure includes an energy meter, a base plate fixedly connected to the bottom side of the energy meter, mounting rails connected to both sides of the bottom of the base plate via clamping mechanisms, multiple mounting holes on the outer wall of the mounting rails, a display screen mounted on the top of the energy meter, a reset button provided on the front side of the display screen, wiring holes on both the front and rear sides of the energy meter, fixing holes on both sides of the top of the energy meter, limit plates fixedly connected to all four sides of the bottom of the base plate, a sliding groove on both sides of the bottom of the base plate, a fixing rod slidably connected to the inner wall of the bottom of the base plate, and a second fixing rod slidably connected to both sides of the bottom of the base plate.

The outer wall of the locking blocks 11 is connected to the base plate 2 through a reset component. By moving the unlocking block 8, the unlocking block 8 will slide on the base plate 2 and drive the locking blocks 11 to unfold. After the locking blocks 11 are adjusted to a suitable position, the base plate 2 is locked into the mounting rail 3. When the unlocking block 8 is released, the locking blocks 11 will clamp the mounting rail 3. The buckle 12 will be fixed to the protruding edge of the mounting rail 3 to prevent the meter 1 from falling out.

[0027] The reset assembly includes a top plate 17 fixedly connected to the top of the locking block 11. A second sliding groove 18 is opened at the bottom of the top plate 17. A movable cover 22 is slidably connected to the bottom of the second sliding groove 18. A spring 15 is provided on the inner wall of the bottom side of the movable cover 22.

[0029] Working principle: Fix the mounting rail 3 into the electrical box through the mounting hole 9. Pull the unlocking blocks 8 on both sides of the base plate 2. When the unlocking blocks 8 are pulled outward, the fixing rod 20 and the movable cover 22 will drive the spring 15 to slide in the top plate 17 and the base plate 2. At the same time, the top plate 17 will slide in the slide groove 13. Then, by pressing down the unlocking block 8, the fixing rod 21 and the movable cover 23 will drive the spring 16 to move in the slide groove 19, thereby adjusting the position of the locking block 11 and the buckle 12. Then, the base plate 2 is snapped into the mounting rail 3, and the unlocking blocks are released. Block 8, spring 15 will drive the movable cover 22 to reset, the reset of the movable cover 22 will lift the top plate 17, drive the buckle 12 to fix the mounting rail 3, spring 26 will push the movable cover 23 to reset, then the movable cover 23 will push the buckle 11 to clamp the mounting rail 3, thereby preventing the meter 1 from falling. After that, after connecting the wire to the wiring hole 6, use a bolt cutter to insert into the fixing hole 7 and tighten the bolt in the fixing hole 7 to fix the wire. Press the reset button 5 to turn on the current, and the current will be displayed on the display screen 4.
