[0002] A distribution cabinet (also known as a distribution box) is the final stage equipment in a power distribution system, mainly used for the distribution, control, and protection of electrical energy. It is suitable for situations where the load is dispersed and there are few circuits, distributing the electrical energy from the previous stage of power distribution equipment to the nearest load. Distribution cabinets are an indispensable and important component of the power system. Their proper selection and correct use are crucial to ensuring the stable operation of the entire system. Due to the influence of the usage environment, some distribution cabinets need to be installed outdoors. However, due to changes in outdoor weather, rainwater can easily enter the cabinet from the heat dissipation vents on both sides during rainy days. Once the rainwater comes into contact with the electrical components installed inside the cabinet, it can easily cause dangerous problems such as short circuits, thus posing a significant safety hazard. Therefore, this application proposes an outdoor distribution cabinet. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figure 1-7 The present invention includes a cabinet 1, with heat dissipation vents 2 on both sides of the cabinet 1. Protective covers 3 are fixedly installed on both sides of the inner wall of the cabinet 1 at the heat dissipation vents 2. The top of the protective covers 3 is not closed. Three cooling fans 4 are fixedly installed between the top of the two protective covers 3 and the inner wall of the cabinet 1. Positioning components 6 are fixedly installed at the center of the bottom of the two heat dissipation vents 2. A detachable dustproof plate 7 that can be rotated around the positioning component 6 is provided in the two heat dissipation vents 2. A dustproof net is provided between the two dustproof plates 7. The protective covers 3 at the heat dissipation vents 2 on both sides of the inner wall of the cabinet 1 can prevent outdoor rainwater from entering the cabinet 1 through the heat dissipation vents 2. The multiple cooling fans 4 at the top of the protective covers 3 can quickly dissipate the heat inside the cabinet 1 from the heat dissipation vents 2.

[0023] like Figure 2 and Figure 5 As shown, the positioning component 6 includes two fixing parts 61 and a rotating part 62. The tops of the two fixing parts 61 are both arc-shaped, and the bottom ends of the two fixing parts 61 are both fixedly installed at the bottom of the heat dissipation vent 2. The rotating part 62 is located between the two fixing parts 61. The rotating shafts at both ends of the rotating part 62 are respectively rotatably inserted into the sides of the two fixing parts 61. The bottom of the rotating part 62 is arc-shaped. The center of the bottom of the two dustproof plates 7 is provided with a notch 14, and the notch 14 at the bottom of the two dustproof plates 7 are respectively fitted into the corresponding positioning component 6. The positioning component 6 can play the role of positioning the bottom of the dustproof plate 7, and can allow the bottom of the dustproof plate 7 to be rotated around the positioning component 6. After being rotated, the dustproof plate 7 can be directly removed for cleaning of surface dust.

[0024] like Figure 5 and Figure 6 As shown, both ends of the top of the rotating part 62 are provided with connecting grooves 13, and both ends of the top of the notch 14 are fixedly installed with connecting rods 15. The two connecting rods 15 on the notch 14 are respectively inserted into the two connecting grooves 13 on the top of the corresponding rotating part 62. Through the mutual engagement of the connecting grooves 13 and the connecting rods 15, the position of the bottom end of the dustproof plate 7 can be constrained, thereby preventing the dustproof plate 7 from shaking randomly.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, a limiting groove 8 is provided on the outer side of the two corners at the top of the heat dissipation vent 2. A screw groove 9 is provided at the center of the two limiting grooves 8. A connecting plate 10 is fixedly installed at both ends of the top of the dustproof plate 7. A bolt 11 is inserted through the two connecting plates 10 and threadedly connected to the corresponding screw groove 9. The bolt 11 can fix the position of the connecting plate 10 in the limiting groove 8, thereby fixing the position of the dustproof plate 7 between the heat dissipation vents 2 on the side of the cabinet 1.

[0026] like Figure 4 and Figure 5 As shown, each limiting groove 8 has an annular groove, and a spring 12 is fixedly connected to each annular groove. The diameter of the screw groove 9 is smaller than the diameter of the annular groove, and the center of the screw groove 9 and the center of the annular groove are located at the same point. When the bolt 11 is unscrewed to remove the dust cover 7, the connecting plate 10 no longer squeezes the spring 12 in the annular groove. At this time, the spring 12 will release its elastic force to push the connecting plate 10 out of the limiting groove 8, so that the dust cover 7 can be easily removed from the heat dissipation port 2.

[0027] like Figure 2 and Figure 6 As shown, the bottom of both protective covers 3 is set to be arc-shaped, and an outwardly inclined guide plate 5 is fixedly installed between the inner walls on both sides of the two protective covers 3. The air blown out by the cooling fan 4 can be discharged from the heat dissipation port 2 along its inclined surface through the guide plate 5.
