Description

Technical Field

[0001] This invention relates to the field of electricity metering technology, specifically to an assembled electricity metering box. Background Technology

[0002] With the continuous advancement of power grid technology, the cost and expense of power supply, distribution, and consumption equipment and facilities are also constantly increasing. As a key component of the power system, modular energy metering boxes play an irreplaceable role in the field of power metering and management. They not only accurately measure various parameters of electricity to provide accurate data for power trading, but also provide data support for power system operation analysis, load forecasting, and power grid planning. Modular energy metering boxes are specialized devices used to measure energy consumption. They consist of a box body, metering components, wiring devices, and protective structures. The box body is mostly made of metal or flame-retardant plastic, possessing corrosion resistance and anti-aging properties. Some outdoor boxes also feature sun and rain protection designs. However, existing modular energy metering boxes have fixed dimensions, making it inconvenient to adjust the size according to needs. Furthermore, when modular energy metering boxes are installed at high locations, it is inconvenient for staff to monitor the situation from a lower position. For example, viewing the data on the meter requires climbing a ladder, which is inconvenient. Therefore, we have proposed a modular energy metering box. Summary of the Invention

The lifting seat and push-pull rod together can then tilt the mounting base and the modular metering box forward and downward, allowing power personnel to view the meter data from the ground without needing to climb to a height, thus offering excellent convenience.

[0016] 4. This modular energy metering box utilizes a combination of worm gear, drive shaft, spur gear, support plate, and worm wheel. When the lifting seat moves downward, it synchronously drives the support plate to flip outward, releasing the support for the lifting seat. When the lifting seat moves upward, it drives the support plate to flip upward, using the support plate to support the lifting seat. This ensures the stability of the lifting seat and push-pull rod in pulling the mounting base and modular metering box, and guarantees the stability of the installation of the modular energy metering box.

Then, the mounting screw holes 54 are inserted into the mounting knock-out holes 20 aligned with the mounting screw holes 54 on the front of the mounting base 49, so that the end thread of the mounting screw hole 54 is threaded into the inner cavity of the mounting screw hole 54. The assembled metering box 1, composed of the left box 6, the right box 7, and the multiple assembled boxes 8, is installed on the mounting base 49 for assembly metering. Install box 1. Additionally, install the electricity meter, circuit breaker, and other equipment on the mounting plate 9 inside the assembled metering box 1. Simultaneously, thread the wires through the wire-knockout holes 48 at the bottom of the left box 6, right box 7, or assembled box 8. Finally, when power personnel need to view the electricity meter data in the assembled metering box 1 from below, fit the hexagonal tube 58 onto the outside of the hexagonal post 57. Rotate the knob 59 to drive the hexagonal post 57, drive rod 56, transmission rod 50, external thread rod 51, and worm gear 62 to rotate synchronously. The meshing transmission between the worm gear 62 and worm wheel 66 drives a transmission shaft 63, spur gear 64, and support plate 65 to rotate. The meshing transmission between the two spur gears 64 drives another transmission shaft 63 and support plate 65 to rotate in the opposite direction.This causes the two support plates 65 to move away from under the lifting seat 52, releasing the support for the lifting seat 52. Simultaneously, the threaded engagement between the external threaded rod 51 and the lifting seat 52 causes the lifting seat 52 to move downwards. The movement of the lifting seat 52 causes the push-pull rod 53 to push the mounting base 49 and the assembled metering box 1 to tilt forward and downwards, allowing power personnel to view the assembled metering box 1 through the metering box cover 10. When it is necessary to return the assembled metering box 1 to its upright position, the reverse rotation of the knob 59 causes the hexagonal column 57, drive rod 56, transmission rod 50, external threaded rod 51, and worm gear 62 to rotate synchronously in reverse. The threaded engagement between the threaded rod 51 and the lifting seat 52 causes the lifting seat 52 to move upwards. The push-pull rod 53 pulls the mounting seat 49 upwards to reset, making the assembled metering box 1 upright. Simultaneously, the worm gear 62, drive shaft 63, spur gear 64, and worm wheel 66 work together to reverse and reset the support plate 65, ensuring its upright position and support for the lifting seat 52. This ensures the stability of the lifting seat 52 and the push-pull rod 53 in pulling the mounting seat 49 and the assembled metering box 1. Furthermore, the worm gear 62 and worm wheel 66 have a reverse self-locking mechanism to prevent the drive rod 50, worm gear 62, and external threaded rod 51 from reversing on their own.
