[0029] In this embodiment, the inverter body 112 is fixedly mounted on the rectangular plate 109 inside the protective box 1. The rectangular plate 109 is at a certain distance from the bottom of the protective box 1 to prevent the inverter body 112 from getting damp. A plurality of through holes 110 are provided on the outer surface of the rectangular plate 109. A rectangular groove 108 is provided at the lower end of the protective box 1. A placement box 107 is movably embedded inside the rectangular groove 108.
