Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.
As shown in fig. 1-3, a power supply box for supplying power, comprising a box body 1 and an electric element 2 fixedly installed inside the box body, a first ventilation grid 3 and a second ventilation grid 4 are respectively arranged on two sides of the box body 1, a first fixing frame 5 is fixedly connected on two sides of an inner cavity of the box body 1, a first dust screen 6 is slidably connected in the first fixing frame 5, a second fixing frame 7 is fixedly connected in the inner cavity of the box body 1 and positioned above the first fixing frame 5, a plurality of second dust screens 8 are slidably connected in the second fixing frame 7, the first dust screen 6 and the second dust screen 8 can be drawn out for convenient cleaning, the first dust screen 6 filters larger impurities and partial dust outside the box body 1, the second dust screen 8 filters air entering the inner cavity of the box body 1, the dust is attached to the second dust screen 8, a fixing plate 9 is fixedly connected in the inner cavity of the box body 1 and positioned above the electric element 2, a servo motor 10 is fixedly installed on the top of the fixing plate 9, an output gear 11 is connected on two sides of the output gear 11, an input gear 12 is fixedly connected in the box body, a fixed support frame 14 is connected on a fan 13, a fan support frame 14 which is fixedly connected on the bottom of the box body and a fan support frame 13 which is connected with a fan 13, a fan support frame 14 which is positioned on the input gear 13 and a fan support frame 13 which is vertically connected with a fan, when the fan, the fan 13, the fan support frame 13 is positioned on the same plane, the support frame 13, a fan 13 is positioned on the input gear 13, the support frame 13 is positioned on the input gear 13, 1 opening one side of box is equipped with the chamber door, and fixed plate 9 and chamber door laminating all are equipped with the passageway between 1 both sides tank wall of box and the fixed plate 9, and 7 tops of second mount and the connection of fixed plate 9 bottom, the width of second mount 7 is the same with the width of passageway, and fixed plate 9 separates 1 inner chamber of box into two spaces, and just two spaces communicate through second mount 7.
