Description

Technical Field

[0001] This utility model relates to the field of electricity metering box technology, and in particular to an electricity metering box with a rainproof structure. Background Technology

[0002] An electricity metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, boxes, etc.

[0003] Currently, although the electricity metering boxes are equipped with upper heat dissipation holes and lower air inlets on both sides to ensure heat dissipation and ventilation, the electricity metering boxes installed outdoors only have a rain shield on the top. When encountering rainy weather, rainwater is not only affected by the wind and splashes everywhere, but may also drip directly onto the ground and bounce into the lower air inlet.

[0004] This design flaw allows rainwater to easily seep into the enclosure, causing water accumulation. This accumulated water evaporates when heated inside the enclosure, increasing the humidity. This damp environment threatens the normal operation and lifespan of electrical equipment, increasing maintenance costs and the risk of failure. Therefore, the applicant has developed a beneficial design and found a solution to the above problems. The technical solution described below arose from this context. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of traditional outdoor power metering box designs and to provide a product with good rain protection and extended service life.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A rainproof power metering box includes a box body. The box body has a heat dissipation area and an air inlet area on its upper and lower sides, respectively. A first through-hole is located below the air inlet area, and a first inclined surface is located below the outlet of the first through-hole. Second rainproof plates are located on the lower sides of both sides of the inner wall of the box body, maintaining a distance from the air inlet area for the entry of gaseous media. An inclined first drainage portion extends from the top of the second rainproof plate, away from the air inlet area. An inclined second drainage portion extends from the bottom of the second rainproof plate and is located within the first through-hole. Blocking portions are located on both sides of the second drainage portion.

[0008] Preferably, the top of the box is provided with a first rain shield, the bottom of the first rain shield is provided with a raised rain shield, and the inner side of the rain shield is provided with a second inclined part.

[0009] Preferably, the heat dissipation area is provided with a plurality of equally spaced heat dissipation holes.

[0010] Preferably, the air inlet area is provided with a plurality of equally spaced air inlet holes, and the two sides of the air inlet area are provided with fixing grooves, and the bottom of the fixing grooves is provided with limiting parts.

[0011] Preferably, the second rain shield has fixing blocks on both sides and is embedded in fixing grooves. The fixing blocks have at least one inclined protrusion and are tightly fitted to the side wall of the fixing groove. The second rain shield has a limiting groove and abuts against the limiting part.

[0012] Preferably, the second drainage portion is provided with a third inclined surface that matches the first inclined surface.

[0013] Beneficial effects:

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features a second rain deflector that effectively intercepts rainwater when it is affected by wind or bounces off the ground, preventing rainwater from entering the enclosure. Simultaneously, a second drainage section guides splashed rainwater away from the enclosure through the first through-hole, preventing internal water accumulation and effectively reducing humidity inside the enclosure. Furthermore, the blocking section ensures that rainwater does not deviate from the drainage path, while the first drainage section guides the incoming cold air in an orderly manner, accelerating air convection and improving heat dissipation efficiency. Moreover, the second rain deflector is located inside the enclosure, significantly improving rainproof performance and extending the service life of the electrical equipment inside the enclosure without altering the overall volume.

An inclined second drainage portion 42 extends from the bottom of the second rainproof plate 4 and is located within the first through hole 31. Blocking portions 421 are located on both sides of the second drainage portion 42. When rainwater is affected by wind or rebounds from the ground, the second rainproof plate 4 will... The system effectively intercepts and prevents rainwater from entering the enclosure 1. At the same time, the second drainage section 42 guides the splashed rainwater out of the enclosure 1 through the first through hole 31, avoiding water accumulation inside and effectively reducing the humidity inside the enclosure 1. In addition, the blocking section 421 ensures that the rainwater does not deviate from the drainage path, while the first drainage section 41 guides the cold air entering the enclosure 1 in an orderly manner, accelerates the air convection speed, and extends the cold air drainage to other areas, increasing the contact area between the cold air and the electrical equipment, thereby improving the heat dissipation efficiency. Furthermore, the second rain shield 4 is set inside the enclosure 1, which not only significantly improves the rainproof performance without changing the overall volume, but also extends the service life of the electrical equipment inside the enclosure 1.

[0030] It is worth mentioning that the air inlet area 3 is provided with several equally spaced air inlet holes 33, and the air inlet area 3 is provided with fixing grooves 34 on both sides. The bottom of the fixing grooves 34 is provided with limiting parts 35. The fixing grooves 34 are used in conjunction with the fixing blocks 43, and the limiting parts 35 play a limiting role in the installation of the second rain shield 4.

[0031] It is worth mentioning that the second rain shield 4 has fixing blocks 43 on both sides and is embedded in the fixing groove 34. The fixing block 43 has at least one inclined protrusion 431 and fits tightly against the side wall of the fixing groove 34. The second rain shield 4 has a limiting groove 44 and abuts against the limiting part 35. The fixing block 43 is connected and fixed to the fixing groove 34 in an interference fit through the protrusion 431, so that the installation can be completed without the need for other tools.
