It should be noted that the outer edge of the top cap 6 is larger than the cross-sectional area of the control cabinet, so as to extend a part of the outer edge outwards to shade the upper part of the control cabinet from rain.

Meanwhile, a gap is provided between the lower edge of the top cap 6 and the front, rear, left and right outer surfaces of the control cabinet to form an air inlet passage. As shown in fig. 5, the inlet passage is opened toward the lower side; can keep effective air intake even in rainy days, and can not enter water.

In addition, the gap between the lower edge of the top cap 6 and the outer surfaces of the front, rear, left and right sides of the control cabinet should be controlled to avoid invasion of sundries in daily use.

Further, the lower edge of the top cap 6 is provided with an inward horizontal folded edge, so that the rainproof effect and the sundry intrusion preventing effect can be further enhanced.

It will be appreciated that the lower edge of the top cap 6 is lower than the top of the control cabinet to form an effective barrier; the specific pressing depth of the top cap 6 can be regulated and controlled according to the actual environment.

In some embodiments, a fan 2 is arranged in the ventilation equipment bin 1, and the fan 2 is communicated with a main air pipe 3 vertically arranged in the control cabinet.
