The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0025] See also Figures 1 to 9In one embodiment, a power distribution cabinet with a dustproof and heat dissipation structure includes an inner cabinet 13, a cabinet door 3, a motor 11, and a fan 12. The inner cabinet 13 is provided with a ventilation slot 17 and a plurality of air inlets 14, and the ventilation slot 17 and the plurality of air inlets 14 are located in the lower half of the inner cabinet 13. The top of the cabinet door 3 is flush with the top of the inner cabinet 13. The motor 11 is fixedly installed at a position corresponding to the plurality of air inlets 14 on the inner cabinet 13, and the output end of the motor 11 is connected to the fan 12. The power distribution cabinet also includes a cooling pipe 4, an outer cabinet 2, and a heat exchange box 1. The cabinet door 3 is rotatably installed on the outer cabinet 2. The cooling pipe 4 is S-shaped from bottom to top and is attached to the outer side surface and the top of the inner cabinet 13. The cooling pipe 4 is first S-shaped and annularly attached to the outer side surface of the inner cabinet 13 from bottom to top, and then S-shaped and straightly attached to the top of the inner cabinet 13 at the top of the inner cabinet 13. The top of the inner cabinet 13 is opened. A groove for accommodating a cooling pipe 4 is provided, the cooling pipe 4 is filled with a coolant, both ends of the cooling pipe 4 are connected to the heat exchange box 1, the outer cabinet 2 is sleeved on the outside of the inner cabinet 13, there is a certain gap between the outer cabinet 2 and the inner cabinet 13, the top of the outer cabinet 2 is open, a plurality of ring baffles 16 are vertically fixedly installed on the inner side of the outer cabinet 2, the plurality of air inlets 14 are located at the position of the last ring baffle 16 below the inner side of the outer cabinet 2, the ring baffle 16 is tilted and points to the axis of the cooling pipe 4, a plurality of air outlets 15 are penetrated and opened at the position corresponding to the ventilation groove 17 on the outer cabinet 2, a drainage plate 20 is fixedly installed on the top of the outer cabinet 2, and baffle blocks 19 are fixedly installed on the top of the two side surfaces adjacent to the cabinet door 3 on the inner cabinet 13, and a drainage groove 18 is opened at the position above the air inlet 14 on the inner cabinet 13 corresponding to the nearest cooling pipe 4.

[0026] In this embodiment, the heat exchange box 1 is actually buried deep underground. The underground is warm in winter and cool in summer to cool the coolant inside the heat exchange box 1. The cooling pipe 4 is S-shaped and attached to the outer side and top of the inner cabinet 13, so as to achieve cooling of the inner cabinet 13. The inner cabinet 13 is tightly fitted and fixed to the internal components. Secondly, a certain gap is provided between the outer cabinet 2 and the inner cabinet 13 to achieve a heat insulation effect. There is also a certain gap between the outer cabinet 2 and the cooling pipe 4, so that the cooling pipe 4 can directly act on the inner cabinet 13 without generating a heat exchange effect with the outer cabinet 2. Therefore, the cooling efficiency of the cooling pipe 4 can be improved while insulating. In this embodiment, a fan 12 is provided to generate an air convection effect. To achieve a heat dissipation effect, air enters through the gap below the guide plate 20, collides with the inclined ring baffle 16 after entering, and then flows downward from the gap between the ring baffle 16 and the cooling pipe 4, and reciprocates through the ring baffle 16. In the process of passing through the ring baffle 16, dust in the air collides with the ring baffle 16 and falls between the cooling pipe 4 and the inner cabinet 13. The cooling pipe 4 is tightly fitted with the outer wall of the inner cabinet 13. Since the ring baffle 16 is inclined and points to the axis of the cooling pipe 4, when the dust falls along the ring baffle 16 to the axis of the cooling pipe 4, the dust will fall along the arc-shaped outer wall of the cooling pipe 4 into the narrow gap between the cooling pipe 4 and the inner cabinet 13. Therefore, through the fan 12 While creating negative pressure, a number of annular baffles 16 are provided to change the direction of airflow, thereby blocking dust from flowing in the gap of the cooling pipe 4, thereby achieving the effect of dust removal. Because the power distribution cabinet itself is mostly arranged outdoors, there will be rainfall. Therefore, when it rains, baffle blocks 19 are provided on both sides of the inner cabinet 13, so that rainwater is drained from the rear of the inner cabinet 13 to the gap between the inner cabinet 13 and the outer cabinet 2. The flow direction of rainwater is the same as that of air. By providing a drainage plate 20, rainwater can be drained and collected, flowing down from the rear of the inner cabinet 13, passing through the annular baffle 16, and then flowing to the gap between the cooling pipe 4 and the inner cabinet 13, and flowing down from the gap between the annular baffle 16 and the cooling pipe 4 and passing through the cooling pipe 4 of the next layer. When the rainwater flows through the cooling When the rainwater flows through the gap between the cooling pipe 4 and the inner cabinet 13, the dust in the gap between the cooling pipe 4 and the inner cabinet 13 can be washed away. The cooling pipe 4 is arranged horizontally, and the sewage with dust flows along the horizontal direction of the cooling pipe 4 to the bending part of the cooling pipe 4 and tilts downward. The bottom of the outer cabinet 2 is provided with an opening at the bending part to facilitate the sewage to flow to the ground. When the rainwater passes through the multi-layer ring baffles 16, it first needs to fill the gap between the cooling pipe 4 and the inner cabinet 13, and then it will flow through the gap between the cooling pipe 4 and the ring baffle 16 to the next layer of ring baffles 16. Therefore, the dust in the gap between the cooling pipe 4 and the ring baffle 16 can be cleaned. When the rainwater flows through the cooling pipe 4, since the cooling pipe 4 is arranged from bottom to top, when the cooling pipe 4 cools the inner cabinet 13,The temperature of the upper cooling pipe 4 is higher than that of the lower cooling pipe 4. Based on this, the rainwater in the present invention flows down from top to bottom, so it can clean the dust and cool the upper cooling pipe 4 at the same time. Secondly, when the rainwater flows through the cooling pipe 4 above the air inlet 14, a drainage groove 18 is provided. Here, the cooling pipe 4 is not tightly connected to the outer wall of the inner cabinet 13, so it does not have the function of storing water. Therefore, the sewage will flow down directly and pass through the air inlet 14 while flowing down, so that the dust at the air inlet 14 can be cleaned to prevent the dust from blocking the air inlet 14.

[0027] See also Figure 8 , Fig. 9 In one embodiment, it also includes a telescopic plate 21 and a water receiving frame 5. The telescopic plate 21 is slidably installed on the inner cabinet 13 through a third spring 29. A support 27 is fixedly installed on the top of the inner cabinet 13.

The rotating shaft 28 is rotatably connected to the support 27. Support blocks 24 are slidably installed at positions on both sides of the water receiving frame 5 on the top of the inner cabinet 13. A driving member is installed on the top of the inner cabinet 13, and the driving member is connected to the support block 24.

[0028] In this embodiment, considering the limited area of ​​the distribution cabinet, the amount of rainwater above is limited and may not be enough to reach the annular baffle 16 above the air inlet 14. Therefore, a water receiving frame 5 is provided to accumulate rainwater. When there is no need for combined cooling by rainwater, the water receiving frame 5 is supported by the support block 24. When combined cooling by rainwater is required or the air inlet 14 is required to be cleaned by rainwater, the support block 24 is driven by the driving member to move, so that the water receiving frame 5 rotates, so that one side of the water receiving frame 5 is pressed against the telescopic plate 21, and squeezes the telescopic plate 21 to lower it, so that the water in the water receiving frame 5 flows down along the side of the water receiving frame 5 from the gap between the telescopic plate 21 and the drainage plate 20. The driving member can be a hydraulic telescopic rod.

[0029] See also Figure 6 In one embodiment, the telescopic plate 21 and the top of the blocking block 19 are inclined.

[0030] In this embodiment, the telescopic plate 21 and the top of the blocking block 19 are inclined, so that the rainwater above the drainage plate 20 can be drained to the top of the inner cabinet 13 in combination with the drainage plate 20, and the cooling pipe 4 on the top of the inner cabinet 13 is cooled, and then flows down from the side of the cabinet door 3.

[0031] See also Figure 8 , Fig. 9In one embodiment, the driving member includes a fixed block 22, an airbag 23, a second spring 25, and a positioning block 26. The fixed block 22 and the positioning block 26 are fixedly installed on the top of the inner cabinet 13. The second spring 25 is connected between the positioning block 26 and the support block 24. The airbag 23 is fixedly installed on one side of the fixed block 22 close to the support block 24.

[0032] In this embodiment, while water is stored by the water receiving frame 5, the deformation of the air bag 23 causes the position of the support block 24 to change in the hot summer, so that the water receiving frame 5 is tilted, and rainwater flows down from the gap between the telescopic plate 21 and the drainage plate 20, so that the water receiving frame 5 can be triggered to rotate according to the external temperature.

[0033] See also Figure 8 , Fig. 9 In one embodiment, the positioning block 26 is an electromagnet, and the support block 24 is made of a magnetically-friendly metal.

[0034] In this embodiment, considering that in the non-hot summer, it is still necessary to clean the dust in the gaps of the cooling pipe 4 and the dust at the air inlet 14, an electromagnet is provided at this time, and the electromagnet is energized to attract the support block 24, causing the water receiving frame 5 to tilt toward the telescopic plate 21.

[0035] See also Figure 1 , Figure 2 , Figure 4 In one embodiment, it also includes a push rod 7, a first mounting plate 6 is fixedly installed on one side of the cabinet door 3, the push rod 7 is fixedly installed on the first mounting plate 6, a sealing frame 8 is slidably installed on the outer cabinet 2, a second mounting plate 10 is fixedly installed on the outer cabinet 2, a first spring 9 is connected between the sealing frame 8 and the second mounting plate 10, the sealing frame 8 corresponds to a plurality of air outlets 15, the sealing frame 8 seals the plurality of air outlets 15 by sliding, and the push rod 7 cooperates with the sealing frame 8.

[0036] In this embodiment, when the cabinet door 3 is closed, the first spring 9 is in a compressed state. At this time, the top rod 7 is against one end of the sealing frame 8, and the air outlet 15 is connected to the outside, thereby realizing the discharge of airflow. When the cabinet door 3 is opened, the first spring 9 is in its original length state. At this time, the top rod 7 is separated from the sealing frame 8, and the sealing frame 8 covers the outer surface of the outlet and is sealed with the surface of the outer cabinet 2, that is, several air outlets 15 are completely sealed. At this time, when the fan 12 is in the working state, the exhaust port of the airflow is the cabinet door 3 area. Therefore, when the staff opens the cabinet door 3 for maintenance, the airflow can be guided to the cabinet door 3, thereby forming a negative pressure, avoiding dust from directly entering the interior of the inner cabinet 13 due to opening the door, thereby causing damage to the internal components.

[0037] See also Figure 3 In one embodiment, a brush 81 is fixedly installed inside the sealing frame 8 .

[0038] In this embodiment, by providing the brush 81 , the dust deposited on the outside of the air outlet 15 can be cleaned during the sliding process of the sealing frame 8 .
