Embodiment 1
[0028] Such as figure 1 As shown, a waterproof and dustproof protective case for electromechanical equipment includes an outer box body 1 and an inner box body 2. The outer box body 1 includes a top cover 11, a side plate 12 and a bottom plate 13, and the side plate 12 includes a front side plate 121, Left side plate, right side plate, rear side plate 122, top cover 11 is slope roof shape, and front side plate 121 is provided with outer box door 1211, and outer box door 1211 is provided with handle; figure 2 As shown, the left side plate, the right side plate or the rear side plate 122 are provided with a through hole 1222. In this embodiment, the through hole 1222 is arranged on the rear side plate 122, and the through hole 1222 is provided with an air intake mechanism 3, and The wind mechanism 3 includes a ventilation plate 31, a dustproof plate 32 and an intake fan 33 arranged horizontally from the outside to the inside. The ventilation plate 31 is inserted in the through ...
Embodiment 2
[0035] Such as Figure 5 As shown, the difference between the present embodiment and the first embodiment is that a rain shield 7 is provided below the air inlet 311, and the rain shield 7 includes a rain holding part 71, an inclined part 72 and a sealing Live in the barrier part 73 of the air inlet 311, the middle part of the inclined part 72 is rotatably connected to the ventilation plate 31 through the pin shaft 76, the inclined part 72 rotates around the pin shaft 76 to drive the rain containing part 71 and the barrier part 73 to swing up and down, The barrier part 73 can seal the air inlet 311 when it swings upwards. In order to facilitate the barrier part 73 to swing and enter the air inlet 311 , a gap is provided at the lower part of the air inlet 311 .
[0036] When it rains, rainwater accumulates in the rain-holding part 71. Under the action of gravity of the accumulated water, the rain-holding part 71 swings downwards, and the inclined part 72 drives the barrier part...
