Description

Technical Field

[0001] This application relates to the field of electricity metering box technology, and in particular to an electricity metering box that is easy to clean. Background Technology

[0002] An electricity metering box is a special box used to centrally install electricity metering devices and supporting electrical components. It is the core equipment for realizing electricity metering and management in the power distribution link of the power system. It is widely used in the power distribution systems of residential buildings and industrial and commercial sites. The electricity metering box usually contains electricity meters, current transformers, voltage transformers, terminal blocks, protective switches, anti-theft components, etc. Some intelligent metering boxes also integrate data acquisition modules and communication modules.

[0003] Currently, a Chinese utility model patent application with a publication date of March 19, 2024, and publication number CN220628532U, discloses a standardized electricity metering box, including an electricity metering main box and a cleaning component. The main box has an adjustment component at its front top, which includes a slide rail and a connecting plate. The connecting plate is slidably connected to one end of the slide rail. The cleaning component is installed on the lower rear side of the connecting plate and includes a cleaning brush and quick-release screws. The cleaning brush is located at one end of the front of the main box, and quick-release screws are threaded onto both the upper and lower front sides of the connecting plate. This standardized electricity metering box allows operators to easily clean dust from the transparent protective plate at the front of the main box, facilitating the viewing of internal components. This convenient operation reduces operation time, improves operator efficiency, and allows for the categorized storage of different types of items, broadening the device's application range.

[0004] The design of easy-to-clean electricity metering boxes in related technologies focuses on the exterior of the box and the observation window of the door. Although it can effectively solve the problem of dust and dirt accumulation on the surface of the box and make it convenient for maintenance personnel to quickly wipe the observation window to check the internal situation, there are still significant cleaning blind spots. That is, the display components inside the box cannot be effectively cleaned, resulting in the data still being unclear after cleaning.

[0005] From a structural perspective, to ensure electricity safety and prevent electricity theft, electricity metering boxes generally adopt a closed box design. The box door is fixed to the box body with a special lock and sealing structure, which cannot be opened by non-maintenance personnel. The cleaning function can only cover the accessible areas on the outside of the box and the inside of the observation window. The internal display components are located inside the closed box and are completely isolated from the external cleaning channel. During long-term use, dust, moisture condensation, and residual water stains are easily attached to the surface of the display components inside the box. Even slight mold and oil stains may occur in humid or oily environments. These stains cannot be removed by external cleaning operations.

[0006] This shortcoming in cleaning directly impacts actual usability: even if maintenance personnel wipe the observation window clean, dirt on the surface of the internal display components will still obscure the numerical display, making it impossible to clearly read key data such as electricity consumption, voltage, and current. This, in turn, affects the accuracy of meter readings and the efficiency of troubleshooting abnormal electricity usage. Forcibly opening the box for cleaning to solve this problem not only violates the original intention of anti-theft design and damages the box's sealing performance, but may also cause electric shock risks due to improper operation, while increasing maintenance workload and time costs. Therefore, it is clear that the existing easy-to-clean electricity metering box design does not take into account the cleaning needs of the internal display components, resulting in significant limitations in cleaning functions and failing to fundamentally solve the core problem of unclear numerical readings.

[0007] Therefore, it is necessary to propose an easy-to-clean electricity metering box to solve the above problems. Utility Model Content

[0033] The design of easy-to-clean electricity metering boxes in related technologies focuses on the exterior of the box and the observation window of the door. Although it can effectively solve the problem of dust and dirt accumulation on the surface of the box and make it convenient for maintenance personnel to quickly wipe the observation window to check the internal situation, there are still significant cleaning blind spots. That is, the display components inside the box cannot be effectively cleaned, resulting in the data still being unclear after cleaning.

[0034] From a structural perspective, to ensure electricity safety and prevent electricity theft, electricity metering boxes generally adopt a closed box design. The box door is fixed to the box body with a special lock and sealing structure, which cannot be opened by non-maintenance personnel. The cleaning function can only cover the accessible areas on the outside of the box and the inside of the observation window. The internal display components are located inside the closed box and are completely isolated from the external cleaning channel. During long-term use, dust, moisture condensation, and residual water stains are easily attached to the surface of the display components inside the box. Even slight mold and oil stains may occur in humid or oily environments. These stains cannot be removed by external cleaning operations.

[0035] This shortcoming in cleaning directly impacts actual usability: even if maintenance personnel wipe the observation window clean, dirt on the surface of the internal display components will still obscure the numerical display, making it impossible to clearly read key data such as electricity consumption, voltage, and current. This, in turn, affects the accuracy of meter readings and the efficiency of troubleshooting abnormal electricity usage. Forcibly opening the box for cleaning to solve this problem not only violates the original intention of anti-theft design and damages the box's sealing performance, but may also cause electric shock risks due to improper operation, while increasing maintenance workload and time costs. Therefore, it is clear that the existing easy-to-clean electricity metering box design does not take into account the cleaning needs of the internal display components, resulting in significant limitations in cleaning functions and failing to fundamentally solve the core problem of unclear numerical readings.

[0036] Based on this, in order to improve the technical problems existing in the related technology that the electricity metering box can only be cleaned on the outside of the box and the observation window, and the internal display components cannot be cleaned because the box is closed, resulting in the value still not being clear after cleaning, and that forcibly opening the box for cleaning may violate the anti-theft design and cause safety risks, the embodiments of this application provide the following solution.
