Description

Technical Field

[0001] The present application relates to the technical field of meter boxes, and in particular to an electric energy meter box. Background Art

[0002] As an integral part of modern power systems, electricity meters play a crucial role in both industrial production and household electricity management. Their core function is to accurately measure energy consumption and monitor real-time power parameters such as power, current, and voltage. This data has a profound impact on efficient energy management, environmental protection, electricity bill settlement, and cost control.

[0003] From a technical perspective, the energy meter box is a highly integrated system. Its sturdy housing and transparent lid form the primary protective barrier, effectively isolating the delicate components within from environmental interference. Within the box, core components such as the power module, current transformer, voltage transformer, metering module, and communication module work together to ensure a stable power supply, precise conversion of current and voltage signals, intelligent calculation of power parameters, and remote data transmission. Furthermore, depending on the application scenario, the energy meter box may also integrate advanced features such as an incoming power distribution unit, electrical protection and control unit, and anti-theft functionality to meet diverse power management needs.

[0004] However, when electricity meter boxes are deployed outdoors, especially in areas prone to sandstorms, a mixture of dust and water vapor easily accumulates on the outer surface of the transparent cover. This not only affects the appearance but, more importantly, interferes with the efficiency of readings. Dust accumulation often requires workers to spend extra time and effort finding the right cleaning tools, which not only reduces work efficiency but can also lead to data errors due to untimely cleaning, affecting the accuracy and timeliness of electricity management. This leaves room for improvement. Summary of the Invention

In this process, the elastic force of the elastic clip 34 is overcome, so that the elastic clip 34 is disengaged from the positioning groove 111; then the cleaning cotton 32 on the cleaning rod 31 can be used to clean the outer surface of the box cover 2; when cleaning is not required under normal circumstances, the cleaning rod 31 is inserted into the accommodating notch 12, and the positioning rod 33 is inserted into the positioning notch 11. At this time, the elastic clip 34 is inserted into the corresponding positioning groove 111.

[0049] Example 2:

[0050] Reference Figure 5 and Figure 6 The embodiment of the present application differs from the embodiment 1 in that an extension plate 13 is integrally formed on two opposite vertical edges of the box body 1, one side of the extension plate 13 is flush with the side of the box body 1 away from the box cover 2, and a protective assembly 4 is provided on the outside of the box body 1, wherein the protective assembly 4 includes a protective cover 41 hinged to the edges of the two extension plates 13, and the two protective covers 41 are integrally formed on the side edges close to each other with a flange 42 bent away from the box cover 2, and a fixing through-hole is opened on the flange 42, and a locking bolt is provided on the outer side of the box body 1 that passes through the fixing through-holes on the two flanges 42;

[0051] When the two protective covers 41 need to be locked, the user rotates the two protective covers 41 toward each other and rotates the two flanges 42 to a state of mutual fit. At this time, the two flanges 42 can be fixed using locking bolts, thereby achieving detachable fixation of the two protective covers 41 in this state; when the two flanges 42 are in a mutually locked state, the protective cover 41 is used to protect the outer side of the box cover 2.

[0052] Reference Figure 6 , an elastic sealing strip 411 made of rubber is fixed to the opening edge of the protective cover 41 by glue. When the two protective covers 41 are locked with each other, the inner side of the elastic sealing strip 411 can be pressed against the outer side of the box cover 2, thereby enhancing the protective performance of the protective cover 41 on the box cover 2;

[0053] An abutment plate 412 is fixedly provided on the side edge of the protective cover 41 close to the box body 1, wherein the abutment plate 412 can rotate synchronously with the protective cover 41. When the two protective covers 41 are in a mutually locked state, one side of the abutment plate 412 can abut against the outer side surface of the positioning rod 33, further abutting and locking the positioning rod 33 in the positioning notch 11.

[0054] Reference Figure 7 and Figure 8 A base plate 5 is provided on the side of the box body 1 away from the box cover 2, and four waist-shaped mounting holes 51 are opened on the base plate 5; four locking plates 14 are fixedly provided on the side edge of the extension plate 13 facing the base plate 5, and a locking groove 52 for inserting the locking plate 14 is opened on the base plate 5; a locking protrusion 141 is fixedly provided on one side of the locking plate 14, and the outer side surface of the locking protrusion 141 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. A locking groove 521 for the locking protrusion 141 to be engaged is opened on the inner wall of the locking groove 52;

[0055] When the energy meter box is installed on a vertical surface, the user pre-inserts the locking plate 14 on the extension plate 13 into the locking groove 52 so that the locking protrusion 141 is inserted into the locking groove 521 to complete the assembly of the box body 1 and the base plate 5, and then fixes the base plate 5 on the designated vertical surface.

[0056] Reference Figure 8 and Figure 9 , locking rods 6 are slidably provided on the upper and lower sides of the two extension plates 13 in the horizontal direction, and a locking gap 522 for the locking rod 6 to be inserted is preset between the side of the locking plate 14 away from the locking protrusion 141 and the inner wall of the locking groove 52, and an elastic return member 7 is provided on the extension plate 13 to drive the locking rod 6 out of the extension plate 13; a guiding inclined surface 61 is provided on the edge of the side of the locking rod 6 away from the base plate 5, wherein the abutment plate 412 can insert the end of the locking rod 6 into the locking gap 522 along the guiding inclined surface 61, thereby providing assembly stability of the box body 1 and the base plate 5;

[0057] When the two protective covers 41 are locked to each other, the abutment plate 412 rotates with the protective cover 41 to squeeze the locking rod 6. At this time, the end of the locking rod 6 away from the abutment plate 412 is inserted into the corresponding locking gap 522 under the squeezing of the abutment plate 412; when the two protective covers 41 are unlocked, the elastic return member 7 drives the end of the locking rod 6 to disengage from the locking gap 522. This state facilitates the disassembly of the box body 1.

[0058] Reference Figure 8 and Figure 9The elastic return member 7 includes a spring 71 in a compressed state, a guide block 72 fixed on the extension plate 13, and a baffle 73 fixed on the outer periphery of the locking rod 6, wherein the guide block 72 is provided with a guide through hole 721 for the locking rod 6 to pass through, and the baffle 73 is located on the side of the guide block 72 away from the base plate 5, and the two ends of the spring 71 are respectively fixed to the side surfaces of the guide block 72 and the baffle 73 close to each other.

[0059] The implementation principle of the embodiment of this application is:

[0060] When the two protective covers 41 need to be locked, the user rotates the two protective covers 41 toward each other and rotates the two flanges 42 until they are in contact with each other. The two flanges 42 can then be fixed with the locking bolts. In this state, one side of the abutment plate 412 can abut against the outer side of the positioning rod 33, and the abutment plate 412 simultaneously inserts the end of the locking rod 6 into the locking gap 522 along the guiding inclined surface 61.

[0061] When the two protective covers 41 are unlocked and unfolded, the abutment plate 412 stops pressing the outer side of the positioning rod 33 and the locking rod 6, which makes it easy to take out the cleaning member 3 and unlock the box body 1 and the base plate 5.
