[0023] Reference Figure 1-4 The utility model embodiment is a waterproof heat dissipation device for a box-type substation, which includes: a bottom plate 6, which serves as the basis of the entire box body, supports the weight of the entire substation and ensures its stability; the lower surface of the bottom plate 6 is fixedly connected with an outer shell 1 to protect the equipment inside the substation from the influence of the external environment; the upper surface of the outer shell 1 is fixedly connected with an outer top cover 2 to prevent external substances from entering the substation; the side surface of the outer shell 1 is provided with an external vent 8 to allow air circulation and help the internal heat dissipation of the substation; the upper surface of the bottom plate 6 is fixedly connected with a base 11 to support an inner shell 10 and internal equipment; the base 11 is located inside the outer shell 1; the side of the base 11 is inclined to guide rainwater or other liquids to the guide port 7; the upper surface of the base 11 is fixedly connected with an inner shell 10 to accommodate and protect the electrical equipment inside the substation; the inner shell 10 is located inside the outer shell 1; the side surface of the inner shell 10 is provided with an inner vent 13 for air circulation to help the internal equipment dissipate heat; the inner vent 13 is staggered with the outer vent 8 to prevent rainwater from directly entering.

[0024] The lower bottom wall of the inner shell 10 is fixedly connected with a limit plate 12 to limit the position of the internal electrical equipment and prevent it from moving or tilting. The upper surface of the inner shell 10 is fixedly connected with an inner top cover 9, which together with the inner shell 10 constitutes a closed space to protect the internal equipment. The upper surface of the inner top cover 9 is inclined to guide rainwater to the diversion port 7. The inner top cover 9 covers the inner shell 10. The side surface of the outer shell 1 is provided with a diversion port 7 to prevent water accumulation inside. The diversion port 7 is located at the lower end of the outer shell 1 and on the outside of the base 11. The upper surface of the base 11 and the inner bottom wall of the outer shell 1 are fixedly connected with a filter plate 14 to prevent debris from entering the substation. The filter plate 14 is located directly above the diversion port 7. The front surface of the outer shell 1 is rotatably connected with a shell door 4 through a hinge 3 to protect the shell. The shell door 4 covers the inner shell 10.

[0025] Working principle: The outer shell 1 and the inner shell 10 form a double-layer structure. The staggered arrangement of the inner vents 13 and the outer vents 8 can prevent rainwater from directly entering the inner shell 10 through the vents. The side tilt design of the base 11 and the upper surface tilt of the inner top cover 9 ensure that even if rainwater enters the space between the inner shell 10 and the outer shell 1, it can quickly flow along the slope to the guide port 7. The guide port 7 is located at the lower end of the outer shell 1 and on the outside of the base 11 to ensure that rainwater can be discharged smoothly and avoid water accumulation. The shell door 4 is connected to the outer shell 1 through the hinge 3 and can be closed when necessary to protect the internal equipment from the external environment. The inner vents 13 and the outer vents 8 allow air to circulate between the inner shell 10 and the outer shell 1 to remove the heat from the internal equipment and achieve a heat dissipation effect. The inner shell 10 fixes the internal equipment through the limit plate 12 to prevent the equipment from moving during use. The steps 5 provide a convenient up and down passage for operators and maintenance personnel. The handle on the shell door 4 is convenient for operators to open and close the shell door 4 to inspect, repair and replace the internal equipment. Through a simple structure, multiple functions such as waterproofing, heat dissipation, and equipment protection are achieved, which not only reduces the manufacturing cost, but also improves the use efficiency and reliability.
