Detailed Description

The following further description of the technology, in conjunction with the accompanying figures 1-6 and the specific embodiments, is provided to assist in understanding the present invention.

A ventilation rainproof door plate with a high protection level for a prefabricated substation comprises an inner door plate 2 and an outer door plate 1 fixedly connected with the inner door plate 2, wherein a shutter 3 and a handle 9 are arranged on the outer door plate 1, and a water outlet hole 31 is formed in the bottom of the shutter 3; the inner door panel 2 is provided with a vent corresponding to the position of the shutter 3, and the left side and the right side of the vent are provided with filter screen pressing plates 7. G4 cotton 4 and a non-woven fabric filter screen 5 are sequentially arranged between the shutter 3 and the vent; a step-shaped enclosing plate 6 is arranged between the outer door panel 1 and the inner door panel 2, the enclosing plate 6 comprises a first step 61 and a second step 62, one end of the first step 61 is provided with a vertical extending part 611, the other end of the first step is connected with the second step 62 through a vertical connecting piece 63, the vertical extending part 611 is fixedly connected with the outer wall of the outer door panel 1, and the end part of the second step 62 is welded on the inner door panel 2. The G4 cotton 4 and the non-woven fabric filter screen 5 are arranged on the first step 61, an interval exists between the non-woven fabric filter screen 5 and the vertical connecting piece 63, a water filtering groove 8 is formed, the height of the water outlet hole 31 on the louver 3 is lower than that of the first step 61, and rainwater is ensured to flow out of the water outlet hole 31 without damaging the inner door panel 2.
