Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distribution cabinets, in particular to an outdoor rainproof distribution cabinet. Background Art
[0002] In an outdoor environment, distribution cabinets often face the problems of rainwater invasion and difficult heat dissipation. Traditional distribution cabinet designs often struggle to meet the requirements of both rain protection and heat dissipation simultaneously.
[0003] Especially in rainy days, moisture is likely to accumulate inside the distribution cabinet, causing the equipment to be affected by moisture, short-circuited, or even damaged. At the same time, a large amount of heat is generated when the distribution cabinet is operating. If the heat dissipation is not smooth, it will also affect the normal operation and lifespan of the equipment.
[0004] Therefore, there is a need for an outdoor distribution cabinet design that can effectively prevent rain and ensure good heat dissipation. Content of the Utility Model
[0005] The purpose of the utility model is to provide an outdoor rainproof distribution cabinet to solve the problems raised in the above background art.

[0007] Preferably, the through hole is directly above the installation opening. After the exhaust fan is started, the gas inside the distribution cabinet body is pumped into the reserved cavity and then discharged through the exhaust port, and the air inlet supplies air to the inside of the distribution cabinet body.
[0008] Preferably, there are two exhaust ports, and the two exhaust ports are symmetrically distributed with respect to the distribution cabinet body. The top end and the bottom end of the exhaust port are both trapezoidal notches.
[0009] Preferably, the top surface of the air inlet is coplanar with the bottom surface of the top plate of the distribution cabinet body.

The length of the long side of the first baffle is equal to the length of the long side of the air inlet. There are two first baffles, and the two first baffles are respectively fixed on the bottom surfaces of the two side notches of the air inlet. The height of the first baffle is less than the height of the air inlet.
[0010] Preferably, a second baffle is fixed on the top surface of the air inlet. The second baffle is located between the two first baffles, and the height of the second baffle is less than the height of the air inlet.
[0011] Preferably, a plurality of drainage holes are formed in the bottom surface of the air inlet. The drainage holes are in an "L" shape and are located between two first baffles.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] The outdoor rainproof power distribution cabinet proposed by the present utility model forms a heat dissipation channel covering the power distribution cabinet body through the design of the awning and the reserved cavity, effectively preventing rainwater from directly wetting the power distribution cabinet. At the same time, the air outlet adopts a special hourglass structure to further block the obliquely blowing rainwater, ensuring that rainwater does not enter the reserved cavity and the interior of the power distribution cabinet; the arrangement of the exhaust fan promotes the air flow inside the power distribution cabinet, extracts the hot air and discharges it through the air outlet, effectively reducing the temperature inside the power distribution cabinet. The design of the air inlet ensures that fresh external air can smoothly enter the power distribution cabinet to supplement the exhausted hot air, thus maintaining a good heat dissipation environment inside the power distribution cabinet.

[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an outdoor rainproof power distribution cabinet, including a power distribution cabinet body 1, a rain awning 2 is fixed on the top surface of the power distribution cabinet body 1, a reserved cavity 3 is arranged inside the rain awning 2, a through opening 6 is opened on the bottom surface of the reserved cavity 3, an installation opening 4 is opened on the top surface of the power distribution cabinet body 1, an exhaust fan 5 is fixed inside the installation opening 4, and an exhaust port 7 is opened on the bottom surface of the reserved cavity 3, and an air inlet 8 is opened on the side plate of the power distribution cabinet body 1; the through opening 6 is directly above the installation opening 4. After the exhaust fan 5 is started, the gas inside the power distribution cabinet body 1 is pumped into the reserved cavity 3 and then discharged through the exhaust port 7, and the air inlet 8 supplements air into the power distribution cabinet body 1.
[0022] There are two exhaust ports 7, and the two exhaust ports 7 are symmetrically distributed with respect to the power distribution cabinet body 1. The top end and the bottom end of the exhaust port 7 are both trapezoidal notches. The reason for setting the exhaust port 7 on the rain awning 2 is to cooperate with the through opening 6 and the reserved cavity 3 to form a heat dissipation channel for the power distribution cabinet body 1 on the rain awning 2, and the heat dissipation channel is covered by the rain awning 2 to prevent rainwater from entering; and the exhaust port 7 is set in an hourglass shape with larger notch widths at both ends and a smaller width in the middle, effectively blocking the rainwater blowing obliquely along with the wind from entering the reserved cavity 3.
[0023] The top surface of the air inlet 8 is coplanar with the bottom surface of the top plate of the power distribution cabinet body 1. There are two air inlets 8, and the two air inlets 8 are symmetrically distributed with respect to the power distribution cabinet body 1. A first baffle 9 is fixed on the bottom surface of the air inlet 8. The length of the long side of the first baffle 9 is equal to the length of the long side of the air inlet 8. There are two first baffles 9, and the two first baffles 9 are respectively fixed on the bottom surfaces of the two side notches of the air inlet 8. The height of the first baffle 9 is less than the height of the air inlet 8. A second baffle 10 is fixed on the top surface of the air inlet 8. The second baffle 10 is located between the two first baffles 9, and the height of the second baffle 10 is less than the height of the air inlet 8; through the staggered distribution of the first baffle 9 and the second baffle 10, when the air inlet 8 introduces air into the power distribution cabinet body 1, in rainy weather, the first baffle 9 and the second baffle 10 block rainwater from entering the power distribution cabinet body 1. A plurality of drainage holes 11 are opened on the bottom surface of the air inlet 8. The drainage holes 11 are in an "L" shape. The drainage holes 11 are located between the two first baffles 9. The rainwater blocked by the first baffle 9 and the second baffle 10 gathers between the two first baffles 9 and flows out through the drainage holes 11.
[0024] A metal mesh sheet 12 is fixed to the bottom surface of the canopy 2. The metal mesh sheet 12 is in an "L"-shaped plate structure. One plate body of the metal mesh sheet 12 covers the exhaust port 7, and the other plate body of the metal mesh sheet 12 is fixed to the side plate of the power distribution cabinet body 1, and the other plate body of the metal mesh sheet 12 covers the air inlet 8. The reason for installing the metal mesh sheet 12 is to block the notches of the exhaust port 7 and the air inlet 8 through the metal mesh sheet 12, so as to avoid external insects from entering while satisfying air circulation.
[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
