Embodiment 1

[0025] Such as figure 1 and figure 2 Commonly shown, an automatic opening type protective cover includes a machine cover 4 . The machine cover 4 is a hemispherical shell-like structure, and the machine cover 4 includes a section steel 9 and a bent steel plate 10 fixed on the outside of the section steel 9 . The hood 4 is provided with two openings 6 and a hood door 3 blocking the openings 6 . The two openings 6 are respectively arranged on opposite sides of the hood 4 , and the position of each opening 6 is correspondingly provided with a hood door 3 . The hood door 3 can move; the hood door 3 can move to open or close the opening 6 . Because the hood is provided with an opening and a hood door blocking the opening, the hood door moves to open or close the opening; therefore the opening can be designed much larger than the opening in the prior art, and is more convenient for maintenance and inspection.

[0026] The automatic opening type protective cover also includes the...
