The initial state of the transmission case 2 is the closed state of the bottom opening;

When it is necessary to move the air-insulated environment-friendly switchgear, the staff first starts the motor 31, the power output shaft of the motor 31 rotates, and then drives the first transmission shaft 3 axially connected with it to rotate, and the rotation of the first transmission shaft 3 drives it The gear column 32 installed concentrically rotates, and the rotation of the gear column 32 drives the first rack plate 33 and the second rack plate 331 which are mirror-imaged on its upper and lower sides to move inwardly and oppositely at the same time, and then pass through the first connecting plate 34 and the second rack plate respectively. The connecting plate 341 respectively drives the first shutter 35 and the second shutter 351 to move inwardly, thereby achieving the effect of opening the bottom opening of the transmission box 2;

Simultaneously when the first transmission shaft 3 rotates, the first sprocket 36 and the second sprocket 37 that are concentric with it are driven to rotate synchronously, and the first sprocket 36 and the second sprocket 37 rotate through the first transmission chain 5 and The second drive chain 51 drives the third sprocket 41 and the fourth sprocket 42 to rotate synchronously; The third sprocket 41 and the second transmission shaft 4 concentric with the fourth sprocket 42 rotate at the same speed, so as to ensure the subsequent motion synchronization;

The rotation of the second transmission shaft 4 drives the driving bevel gear 43 installed concentrically with it to rotate, the rotation of the driving bevel gear 43 drives the driven bevel gear 44 meshed with it to rotate, and the rotation of the driven bevel gear 44 drives the third transmission shaft 45 installed concentrically with it to rotate , the rotation of the third drive shaft 45 drives the threaded screw 47 matched with it to move down, and then the fixed plate 48 installed at the bottom of the screw 47 moves down, so that the universal wheel 49 at the bottom of the fixed plate 48 lifts up the entire switch cabinet Body 1 until the universal wheel 49 is completely moved out of the transmission box 2, and the motor 31 is turned off. At this time, the staff can easily move the air-insulated and environmentally friendly switchgear, avoiding the situation of manual handling of the switchgear, reducing labor intensity and improving labor efficiency. efficiency;

When the air-insulated environment-friendly switchgear moves to the designated position, the staff starts the motor 31 to reverse the motor 31. The operation steps are as above, and then the universal wheel 49 can be retracted to the transmission box 2 at the same time, so that the first shroud 35 and the second shroud 351 are in a tendency to expand and move outward until completely closing the opening at the bottom of the transmission case 2, which can prevent debris from entering the transmission case and ensure the safety of the entire transmission structure.
