Description

Technical Field

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

[0002] The electric meter box, a protective device specifically designed to house electrical energy meters, plays a crucial role in household electrical systems. As a crucial component of the power system, it not only houses the meter but also distributes current and protects circuits. With the continuous advancement of electronic technology, electric meter boxes have become increasingly intelligent, enabling more precise monitoring and measurement of electrical energy, as well as effective control of its flow, thereby preventing potential safety hazards such as overloads.

[0003] In related technologies, the structure of an electricity meter box is primarily composed of two parts: the meter box and the cover. The meter box is typically made of aluminum alloy, which is not only durable but also easy to read and maintain. The cover ensures the internal seal of the meter box, preventing external factors from interfering with the meter. Furthermore, modern meter boxes may also be equipped with intelligent monitoring devices for real-time monitoring of energy usage, improving the efficiency and accuracy of electricity management.

[0004] During operation, devices within the meter box, such as circuit breakers, fuses, and electrical transformers, continuously generate heat, causing the internal temperature of the meter box to rise. Although heat dissipation is considered in the design and manufacturing of meter boxes, such as by providing heat dissipation vents on the side walls, in practice, the heat dissipation performance of some meter boxes is still poor and cannot meet the requirements. Poor heat dissipation can occur, and if this occurs, the temperature of the meter box will continue to rise, potentially causing overload and failure of circuit equipment, affecting the normal operation of the power system, and even damaging household appliances, posing a fire hazard. This leaves room for improvement. Summary of the Invention

When the temperature inside the box 1 rises, the heat-conducting fan 14 activates, allowing cool air from outside to enter the box 1 through the air inlets 11 and air deflectors 12, dissipating heat from the electrical modules. Hot air, on the other hand, enters the connection cavity 21 through the mounting opening 13 at the top of the box 1 and is ultimately discharged through the exhaust port 22 on the top cover 2, achieving a cooling effect.

[0034] Example 2: Reference Figure 5 and Figure 6 A protective assembly 5 is provided on the outside of the box body 1, wherein the protective assembly 5 includes a protective cover 51 provided on the outside of the box body 1 and opening downward, wherein the protective cover 51 is provided above all the air deflectors 12 on the same side of the box body 1; the lower side of the protective cover 51 is hinged to the outside of the box body 1 near the edge of the box body 1, and the outside of the box body 1 is provided with a fastener 52 for fixing the box body 1 to a vertical state and a locking member 53 for fixing the protective cover 51 when it is in a horizontal state; The protective cover 51 reduces the possibility of external rainwater or other impurities entering the interior of the box 1 through the air inlet 11. When the interior of the meter box needs to be inspected later, the fasteners 52 that fix the protective cover 51 can be released, and the protective cover 51 can be rotated downward to a horizontal state. At this time, the tools required for inspection can be placed on the upper side of the horizontal protective cover 51.

[0035] Reference Figure 7 and Figure 8The fastener 52 includes a fastening bolt 521 located outside the box body 1 and a fastening plate 522 fixed to the upper part of the protective cover 51.

The ends of the cross bar 41 are provided with locking grooves 411 for the locking blocks 61 to be inserted. An adjustment through hole 16 is provided on the box body 1, and an elastic extrusion member 62 is provided on the locking rods 6 and is located in the adjustment through hole 16. The elastic extrusion member 62 includes a first spring 623 in a compressed state and an extension rod 621 fixed to the locking rod 6. A first baffle 622 is fixed to the outer periphery of the extension rod 621. An adjustment groove 161 for the first baffle 622 to be placed is defined on the outer opening edge of the adjustment through hole 16. The two ends of the first spring 623 are fixedly connected to the inner side of the first baffle 622 and the bottom side of the adjustment groove 161 respectively. When the protective cover 51 is in the vertical state, the protective cover 51 squeezes the outer end of the extension rod 621. At this time, the first spring 623 is compressed and the locking block 61 is inserted into the locking groove 411; after the protective cover 51 rotates downward, the protective cover 51 releases the squeezing of the elastic extrusion member 62. At this time, under the action of the first spring 623, the locking block 61 falls out of the locking groove 411.

[0037] Reference Figure 11 and Figure 12 , support plates 17 located below the protective cover 51 are fixedly provided on the two opposite sides of the lower part of the box body 1, and the support plates 17 are flush with the bottom side of the box body 1; two support through holes 171 are provided on the support plate 17, and a support rod 7 is slidably arranged in the support through holes 171.

When the protective cover 51 rotates downward to a horizontal state, the protective cover 51 squeezes the upper end of the support rod 7 to make the moving wheel 71 disengage from the support groove 172, thereby facilitating the short-distance movement of the meter box; when the protective cover 51 is in a vertical state, the support rod 7 elastically abuts against the lower side of the protective cover 51 under the action of the elastic reset member 73.

[0038] The implementation principle of the embodiment of this application is: When it is necessary to inspect the inside of the electric meter box, the fasteners 52 that fix the protective cover 51 can be released, and the protective cover 51 can be rotated downward to a horizontal state. At this time, the protective cover 51 can be used as a temporary placement platform for maintenance tools, thereby improving maintenance efficiency. At the same time, by providing a locking rod 6 and an elastic extrusion member 62, the protective cover 51 can be automatically locked when the protective cover 51 is in a vertical state to ensure its stability; and when the protective cover 51 is rotated, the locking rod 6 is automatically unlocked for easy operation. In addition, the support rod 7 and the elastic reset member 73 provided at the lower part of the box body 1 can not only provide support when the protective cover 51 is horizontal, facilitating the short-distance movement of the electric meter box, but can also automatically reset when the protective cover 51 is vertical, elastically abutting the protective cover 51, thereby enhancing the stability and practicality of the structure.
