[0002] A power distribution cabinet is a device used in power systems, primarily for the conversion, distribution, and control of electrical power. It typically consists of multiple electrical components, such as circuit breakers, contactors, relays, and transformers. Power distribution cabinets are widely used in industry, buildings, and other locations requiring power supply and management. In some cases, power distribution cabinets need to be installed outdoors or in damp environments. Therefore, rainproof design is particularly important for power distribution cabinets.

[0003] Existing power distribution cabinets, such as the Chinese application with application number 201320721955.7, entitled "Powerless Forced Exhaust Box Type Distribution Cabinet," include a cabinet body with ventilation vents on the top. A powerless fan is installed on the ventilation vents, and the fan is sealed to the vents. By increasing the ventilation vents, airflow between the inside and outside of the cabinet is promoted, thereby reducing the temperature inside the cabinet and improving the working environment of the internal components.

[0004] The existing technology has the following drawbacks: In the above-mentioned power distribution cabinet, the heat dissipation vent is set on the cabinet body, and the heat dissipation vent is directly connected to the inside of the cabinet and the external environment. When it rains, rainwater can easily enter the inside of the cabinet through the heat dissipation vent. The inside of the power distribution cabinet may be damaged by moisture, which may even cause short circuits, component corrosion and other problems. Therefore, there is room for improvement. Utility Model Content

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Figure 1 A schematic diagram of the overall structure of the rainproof and splashproof high-ventilation power cabinet provided in this embodiment of the utility model; Figure 2 A cross-sectional view of the dynamic rainproof and splashproof high-ventilation power cabinet provided in this embodiment of the utility model; Figure 3 for Figure 2 Enlarged view of point A in the middle; Figure 4 for Figure 2 Enlarged view of point B in the middle.

[0028] The rainproof and splashproof high-ventilation power cabinet provided in this embodiment is applied to outdoor scenarios that require power distribution, control and management. In this embodiment, the structure of the power cabinet is improved so that the power cabinet maintains good air circulation inside the cabinet, while preventing rainwater from entering the cabinet from the air inlet and air outlet, thus maintaining a dry environment inside the cabinet.

[0029] Please see Figures 1-4 The rainproof and splashproof high-efficiency exhaust cabinet provided in this embodiment includes a housing 1 and an exhaust fan 2. The exhaust fan 2 is installed inside the housing 1. The housing 1 is provided with an air inlet 3 and an air outlet 4. The air inlet 3 is located at the lower end of the housing 1, and the air outlet 4 is located at the upper end of the housing 1. The air inlet 3 is provided with a rainproof component 5, which is used to prevent external water from splashing into the housing 1. The air outlet 4 is provided with a splashproof component 6, which is used to prevent external water from splashing into the housing 1.

[0030] Specifically, the exhaust fan 2 is used to promote airflow inside the housing 1, so that hot air can be discharged in time, thereby reducing the temperature inside the housing 1; the rainproof component 5 and the splashproof component 6 are set to effectively prevent rainwater from entering the housing 1 from the air inlet 3 and the air outlet 4, maintain a dry environment inside the housing 1, avoid electrical components from being soaked by rainwater and short-circuiting or even malfunctioning, reduce maintenance and repair costs caused by electrical faults, and make the equipment operate more stably.

[0031] Please see Figure 2 and Figure 3 Furthermore, the rainproof component 5 includes a first splash guard 51, which is disposed on the side wall of the housing 1 to prevent rainwater from entering the housing 1 through the air inlet 3. A first channel 52 is formed between the first splash guard 51 and the side wall of the housing 1. Specifically, after the exhaust fan 2 is started, outside air enters the housing 1 through the air inlet 3. The first splash guard 51 blocks the rainwater entering the air inlet 3, reducing the amount of moisture in the air mixed into the housing 1, which helps to keep the inside of the housing 1 dry.

[0032] Please see Figure 2 and Figure 3 Furthermore, the rainproof component 5 also includes a waterproof plate 53, which is disposed at the bottom of the housing 1. The waterproof plate 53 is used to prevent rainwater from entering the interior of the housing 1. A second channel 54 is formed between the waterproof plate 53 and the housing 1, and the first channel 52 is connected to the second channel 54. Specifically, outside air enters the interior of the housing 1 through the first channel 52 and the second channel 54. Water droplets condensed on the first splash plate 51 fall into the second channel 54. The waterproof plate 53 prevents water droplets in the second channel 54 from entering the housing 1. When the water droplets in the second channel 54 accumulate to a certain height, the rainwater is discharged from the air inlet 3 to the outside of the housing 1, keeping the interior of the housing 1 dry and preventing water droplets condensed on the first splash plate 51 from accumulating at the bottom of the housing 1, thus maintaining a dry environment inside the housing 1.

[0033] Please see Figure 2 and Figure 4 Furthermore, the splash guard 6 includes a second splash guard 61, which is disposed on the top of the housing 1 to prevent rainwater from entering the housing 1 from the air outlet 4. A third channel 62 is formed between the second splash guard 61 and the housing 1, and the second channel 54 communicates with the third channel 62. Specifically, under the action of the exhaust fan 2, the air inside the housing 1 is discharged to the third channel 62 and discharged from the third channel 62 to the air outlet 4. The second splash guard 61 blocks rainwater entering the housing 1 from the air outlet 4, preventing rainwater from entering the housing 1 from the air outlet 4. More specifically, the air outlet 4 is arranged vertically, and the horizontal part of the second splash guard 61 blocks the air outlet 4, preventing rainwater from entering the housing 1 from the bottom up, thus ensuring the air permeability and waterproofness of the air outlet 4.

[0034] Please see Figures 1-4 Furthermore, the enclosure 1 is provided with a door 7, which includes a flow guide layer 71 and a sealing layer 72. The flow guide layer 71 covers the outside of the sealing layer 72 and is used to prevent rainwater on the door 7 from entering the sealing layer 72. Specifically, the sealing layer 72 provides a tight sealed environment to ensure that the interior of the enclosure 1 is not affected by external moisture, dust, and impurities; the flow guide layer 71 effectively prevents moisture from entering the interior of the enclosure 1 through the door 7 by reducing direct contact between rainwater and the sealing layer 72, thereby protecting the electrical components and circuits inside the enclosure.

[0035] Please see Figure 2 , Figure 3 and Figure 4 Furthermore, the flow guiding layer 71 includes a first flow guiding channel 711, a first flow guiding plate 712, a second flow guiding plate 713, and a third flow guiding plate 714. The top of the first flow guiding plate 712 is used to guide rainwater into the first flow guiding channel 711. The bottom of the first flow guiding plate 712 is provided with a second flow guiding channel 715. A fourth channel 716 is formed between the first flow guiding plate 712 and the second flow guiding plate 713. The fourth channel 716 is used to guide rainwater in the first flow guiding channel 711 into the second flow guiding channel 715. The third flow guiding plate 714 is provided at the bottom of the second flow guiding plate 713 and is used to guide rainwater in the second flow guiding channel 715 to the outside of the housing 1.

[0036] Specifically, rainwater dripping onto the top of the first guide plate 712 flows into the first guide channel 711. Since a fourth channel 716 is formed between the first guide plate 712 and the second guide plate 713, when the rainwater in the first guide channel 711 accumulates to a certain height, the rainwater in the first guide channel 711 flows into the second guide channel 715 along the fourth channel 716. When the rainwater in the second guide channel 715 accumulates to a certain height, the accumulated water in the second guide channel 715 flows to the ground along the outside of the third guide plate 714. Through the above arrangement, the rainwater on the box door 7 is effectively diverted to the ground, avoiding rainwater from entering the box 1 and the splashing of rainwater, which helps to keep the inside of the box 1 dry.

[0037] Please see Figure 2 , Figure 3 and Figure 4 Furthermore, the top of the sealing layer 72 is fixed to the first guide channel 711, and the base of the sealing layer 72 is fixed to the third guide plate 714. Specifically, since the top of the sealing layer 72 is fixed to the first guide channel 711 and the base of the sealing layer 72 is fixed to the third guide plate 714, rainwater on the guide layer 71 flows from the first guide channel 711 through the fourth channel 716 into the second guide channel 715, and cannot directly enter the sealing layer 72, further ensuring the waterproof performance of the housing 1.

[0038] Furthermore, the second guide plate 713 is extended along the axial direction of the first guide groove 711 and the second guide groove 715. Specifically, the extended second guide plate 713 can effectively cover the length of the first guide groove 711 and the second guide groove 715, ensuring that rainwater dripping in the first guide groove 711 can be quickly guided into the fourth channel 716 and the second guide groove 715, thus ensuring the guiding effect of the second guide plate 713.

[0039] In summary, the rainproof and splashproof high-ventilation power cabinet provided in this embodiment has advantages such as high air permeability and good waterproof performance.

[0040] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
