[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] This embodiment is a waterproof outer shell structure for a low-voltage cabinet.
[0026] like Figures 1-5 As shown, the device includes a low-voltage cabinet housing 1. The upper outer surface of the low-voltage cabinet housing 1 has first air outlets 5 on the left and right sides. The upper part of the first air outlets 5 is provided with a top exhaust waterproof structure 4, which includes a protective cover 8, a second air outlet 9, a second protective net 10, a base plate 11, a side air outlet protective net 12, a drain outlet 13, a third protective net 14, a water receiving tray 15, a horizontal support rod 16, a vertical support rod 17, a surrounding plate 18, and a third air outlet 19. A cooling fan 7 is fixedly installed at the bottom of the back of the low-voltage cabinet housing 1. One side of the cooling fan 7 is covered with an air inlet protective cover 2, which is fixedly installed at the bottom of the back of the low-voltage cabinet housing 1.
[0027] A first protective net 6 is fixedly installed at the bottom of the inner cavity of the air inlet protective cover 2, and a rounded chamfer 3 is formed on the upper part of one side of the outer surface of the air inlet protective cover 2; the base plate 11 is fixedly installed on the upper outer surface of the low-voltage cabinet housing 1, and the third air outlet 19 is opened in the middle of the upper outer surface of the base plate 11, and the third air outlet 19 is located directly above the first air outlet 5; the surrounding plate 18 is fixedly installed on the upper outer surface of the base plate 11, the third air outlet 19 is located inside the surrounding plate 18, the second air outlet 9 is opened in the middle of the upper outer surface of the protective cover body 8, and the second protective net 10 is fixedly installed. In the second air outlet 9; the water receiving plate 15 is fixedly installed in the upper part of the inner cavity of the protective cover 8, the drain outlet 13 is opened in the middle of the rear end of the protective cover 8, and the drain outlet 13 is connected to the bottom of the inner cavity of the water receiving plate 15; the horizontal support rods 16 are installed at equal intervals between the outer wall of the water receiving plate 15 and the inner wall of the protective cover 8, the vertical support rods 17 are fixedly installed between the lower outer surface of the horizontal support rods 16 and the upper outer surface of the substrate 11, and the side air outlet protective net 12 is fixedly installed between the lower outer surface of the protective cover 8 and the upper outer surface of the substrate 11.
[0028] It should be noted that this utility model is a waterproof outer shell structure for a low-voltage switchgear. The top exhaust waterproof structure 4 is located above the first air outlet 5 at the top of the low-voltage switchgear shell 1. Through the operation of the cooling fan 7, fresh air from the outside enters the bottom of the inner cavity of the low-voltage switchgear shell 1 and is then discharged through the first air outlet 5 at the top of the low-voltage switchgear shell 1. The heat dissipation air duct runs from low to high, improving heat dissipation. After the air enters the interior of the top exhaust waterproof structure 4, as shown in the attached instruction manual... Figure 4 As shown, air is discharged between the protective cover 8 and the base plate 11 at the position of the side air outlet protective net 12 and the position of the second air outlet 9. When it rains, rainwater enters the interior of the protective cover 8 through the second air outlet 9, and is guided by the water receiving plate 15. The rainwater is discharged through the drain outlet 13, which plays a waterproof role. The enclosure 18 plays a waterproof role and prevents rainwater from entering the third air outlet 19 through the position of the side air outlet protective net 12, thereby improving the protection. The air inlet protective cover 2 is set to protect the position of the top exhaust waterproof structure 4. The position of the air inlet is downward, which plays a certain role in rain protection.
