[0020] The electric control box 3 includes a front side plate 4 and a box body 5, and the front side plate 4 is fixed at the opening of the box body 5 through box body bolts (not shown in the figure). An operation space 13 is arranged between the support frames 1, and the operation space 13 is located directly below the main cabinet 2. The front side plate 4 faces the operation space 13 and is opened or closed within the operation space 13.

[0021] Flanging bent towards the opening of the box body 5 is arranged on the four peripheries of the front side plate 4, and an inclined edge 42 inclined upward is arranged at the end of the top flanging 41 located at the top. The box body 5 includes a rear side plate 51, an upper side plate 52, a lower side plate 53, a left side plate 54 and a right side plate 55, and an upper flanging 56 bent towards the opening is arranged at the front end of the upper side edge 52, and the inclined edge 42 abuts against the upper flanging 56 to prevent rainwater from entering the electric control box 3 from the top of the electric control box 3.

[0022] A left flanging 57 bent towards the opening is arranged at the front end of the left side plate 54, a left limiting edge 58 extending forward is arranged at the top of the left flanging 57, a right flanging (not shown in the figure) bent towards the opening is arranged at the front end of the right side plate 55, and a right limiting edge 510 extending forward is arranged at the top of the right flanging. The left limiting edge 58 and the right limiting edge 510 respectively abut against the inner surface of the front side plate 4, the left flanging 57 abuts against the left flanging 43 located on the left side of the front side plate 4, and the right flanging abuts against the right flanging 44 located on the right side of the front side plate 4. The left limiting edge 58 and the right limiting edge 510 are provided to prevent rainwater from entering the electric control box 3 from the left and right sides of the electric control box 3.

[0023] A lower hem 511 that bends towards the opening is provided at the front end of the lower side plate 53. A plurality of cabinet threaded holes 512 are provided on the lower hem 511. A plurality of threaded through holes 45 corresponding to the cabinet threaded holes 512 are provided on the front side plate 4. Cabinet bolts are arranged in each threaded through hole 45. Arranging the cabinet bolts not only fixes the front side plate 4 and the cabinet 5 together, but also prevents rainwater from entering the electric control cabinet 3 from the bottom of the electric control cabinet 3.
