In the normal use of the device, if there is rainfall weather, the rainwater can fall in water catch bowl 3 through the guide of apron 2, after the rainwater gets into water catch bowl 3, can enter into water inlet 33 through the aperture at box 1 top, and then enter into water tank 26 through water inlet 33, the rainwater is in the water tank 26 after, on the one hand can increase the weight of box 1 bottom, and then make the focus of box 1 reduce, and then make the stability of box 1 increase, on the other hand, the rainwater in the water tank 26 can also be used for the cleanness to transparent resin plate 9, prevent that the condition of the unable internal structure of box 1 that leads to because of the dirt is more from taking place on the transparent resin plate 9.
When the internal structure cannot be observed due to more dirt on the transparent resin plate 9, the electric slide rod 8 is enabled to be in contact with the switch of the water pump through the ascending of the electric slide rod 8, the water pump in the water outlet hole 34 pumps water from the water tank 26, water in the water tank 26 can enter the L-shaped pipe through the water outlet hole 34 under the pumping of the water pump and then enter the transverse pipe 29, after entering the transverse pipe 29, the water can be sprayed on the transparent resin plate 9 through the through hole of the guide transparent resin plate 9, and then the electric slide rod 8 drives the curtain cloth 11 to reciprocate up and down to effectively wipe the transparent resin plate 9 through the ascending and descending of the electric slide rod 8, so that the transparency of the transparent resin plate 9 is improved, and a technician can effectively observe the internal structure of the box 1. After the transparent resin plate 9 is cleaned, the electric slide bar 8 is abutted against the switch again by the rising of the electric slide bar 8, so that the water pump is turned off, and after the water pump is turned off, the electric slide bar 8 is stopped below the switch and at a position which is not abutted against the switch. Can effectually prevent that the water pump from drawing water too much, and lead to the water to flow too big, on the other hand also can avoid the water in the water tank 26 to use too fast.
After the transparent resin plate 9 is washed, water flows downwards along the transparent resin plate 9, the water flows into the water tank at the bottom of the fixed frame 7, then enters into the water receiving tank 5 through the through hole at the bottom of the water tank, and then flows into the evaporation tank 4 below the two ventilation windows 6 under the connection of the water receiving tank 5, after the evaporation tank 4 receives water, the water can effectively evaporate in the evaporation tank 4, and the evaporation of the water absorbs heat, so that on one hand, the heat on the box body 1 can be taken away through the evaporation tank 4, on the other hand, the temperature outside the ventilation windows 6 can be reduced, and when the wind blows, the inside of the box body 1 can be effectively radiated, the radiating effect of the ventilation windows 6 is improved, and meanwhile, the water in the water tank 26 can be fully utilized.
When the fuse 21 blows or fails, the lifting base 27 descends, the first contact 13 is separated from the first wire head 19, the second contact 23 is separated from the second wire head 24, the fuse 21 is not electrified any more, after the fuse 21 is not electrified, the sliding plate 16 descends along with the descending of the lifting base 27 under the action of the elastic force exerted by the spring on the inner plate 32, the sliding plate 25 descends along with the descending, and when the sliding plate 16 is abutted against the wall plate at the bottom of the guide groove on the insulating plate 15, the air holes formed in the inner plate 32 are retracted into the wall plate at the side edge of the air guide hole on the insulating plate 15, so that the air guide hole on the insulating plate 15 is effectively plugged. Along with the decline of lifting base 27, when lifting base 27 descends to the bottom separation of extension board 25 and insulation board 15, insulation board 15 can rotate to the direction of install bin 22 under the action of the gravity of slide 16, and then make the insulation board 15 that two air guides were plugged rotate to the top of install bin 22, on the one hand can carry out effectual wall to first line 19, make the technician can obtain effectual safety guarantee when changing fuse 21, on the other hand insulation board 15 is when rotating to the top of install bin 22, slide 16 can with guide plate 30 butt, and then make slide 16 establish with earth connection 17 under the butt of guide plate 30 and be connected, and then the effectual condition that prevents first line 19 to break through insulation board 15 takes place, further improved insulation board 15 and to the partition protection of install bin 22.
When the lifting base 27 is lowered to the bottommost state, the door panel 10 is opened, and after the new fuse 21 is replaced in the installation box 22, the door panel 10 is closed, by lifting the lifting base 27, after the extension plate 25 is abutted against the insulating plate 15, the extension plate 25 can push the insulating plate 15 to be vertical in a short time along with the lifting base 27, so that the insulating plate 15 is abutted against the sealing sleeve 31, when the lifting base 27 is lifted, and the extension plate 25 is lifted to be in contact with the sliding plate 16, at the moment, the first contact 13 and the second contact 23 are close to the first wire end 19 and the second wire end 24, after the sliding plate 16 is contacted with the extension plate 25, the sliding plate 16 is lifted by the continuous lifting of the lifting base 27, so that the ventilation holes on the inner plate 32 are communicated with the air guide holes, and the ventilation window 6 can effectively ventilate the interior of the box 1, on the other hand, the first contact 13 and the second contact 23 can be respectively abutted against the first wire head 19 and the second wire head 24, at this time, the first contact 13 and the second contact 23 are respectively disconnected and abutted against the first wire head 19 and the second wire head 24 through the continuous three-time short-distance lowering and lifting of the lifting base 27, on the one hand, in order to prevent the risk of personnel being electrified when the transformer is powered off, on the other hand, the sliding plate 16 can be driven to lift and descend through the continuous three-time short-distance lowering and lifting of the lifting base 27, and then the insulating plate 15 scrapes dust attached to the inner plate 32 and discharges the dust through the ventilation window 6, so that the ventilation efficiency of the ventilation window 6 is ensured, and meanwhile, the device also has a certain dustproof effect through the blocking of the insulating plate 15.
