Insert the two sets of connecting support blocks 4 into the connecting grooves 7 so that the electric telescopic rod 5 can be restored to its original shape to clamp the aerial work frame 2 and the lower connecting rotating seat 6. The lower connecting rotating seat 6 is rotatably connected to a rotating arm 8. The lower part of the rotating arm 8 is fixedly connected to multiple sets of wind direction fins 9. Side slide grooves 10 are symmetrically provided on both sides of the rotating arm 8. One set of side slide grooves 10 is rotatably connected to a long screw 11 inside, and the other set of side slide grooves 10 is fixedly connected to a guide rod 12 inside. A drive motor 13 is fixedly connected to the top of the rotating arm 8. The rotating shaft of the drive motor 13 passes through the rotating arm 8 to the side slide groove 10 and is connected to the long screw One end of the screw 11 is fixedly connected, one end of the long screw 11 is fixedly connected to the rotating shaft of the drive motor 13, and the other end of the long screw 11 is rotatably connected to the inner wall of the side slide 10. A movable slider 14 is provided below the rotating arm 8. The movable slider 14 is adapted to the two sets of side slides 10. A threaded through hole 15 and a guide through hole 16 are provided on the side of the movable slider 14. The threaded through hole 15 is adapted to the long screw 11, and the guide through hole 16 is adapted to the guide rod 12. A counterweight box 17 is fixedly connected to the bottom of the movable slider 14. A plurality of fixed slots 18 are provided on the side of the counterweight box 17. There are multiple groups of fixing screw holes 19 corresponding to the position below the fixing slot 18 on the side. A counterweight block 20 is provided on the inner side of the counterweight box 17. A fixing through hole 21 is provided on the side of the counterweight block 20. A fixing screw 22 is provided on the side of the fixing through hole 21. The counterweight block 20 is adapted to the fixing slot 18. In the initial state, the counterweight box 17 is located directly below the lower connecting rotating seat 6. When the counterweight block 20 needs to be fixed to the counterweight box 17, only a selected number of counterweight blocks 20 need to be inserted into the fixing slot 18, and the fixing screw 22 is used to pass through the fixing through hole 21 and threadedly connect it to the fixing screw hole 19.

[0026] The working principle of the utility model is as follows: first, according to the working environment and wind conditions, the appropriate number of counterweight blocks 20 is selected, the selected number of counterweight blocks 20 are inserted into the fixing slots 18 of the counterweight box 17, and the counterweight blocks 20 are ensured to be firmly inserted, and the fixing screws 22 are used to penetrate the fixing through holes 21 of the counterweight blocks 20 and are screwed together with the fixing screw holes 19 of the counterweight box 17 to complete the fixing of the counterweight;

[0027] Start the electric telescopic rod 5 to retract it, driving the two sets of connecting support blocks 4 closer to each other, align the retracted connecting support blocks 4 with the connecting grooves 7 on the lower connecting rotating seat 6, and insert them into them. Release the electric telescopic rod 5 to restore it to its original state. The connecting support blocks 4 are firmly clamped in the connecting grooves 7 by the extension force of the electric telescopic rod 5, thus achieving a stable connection between the aerial work frame 2 and the lower connecting rotating seat 6.

[0028] The wind direction fins 9 under the rotating arm 8 will rotate naturally with the change of wind direction, and at the same time drive the rotating arm 8 to rotate to a suitable angle. At this time, the counterweight box 17 in the initial state is located directly below the lower connecting rotating seat 6. According to the size of the wind, the driving motor 13 is started to drive its rotating shaft to start rotating, thereby driving the long screw 11 to rotate synchronously in the side slide groove 10. Since the threaded through hole 15 of the moving slider 14 is adapted to the long screw 11, and the guide through hole 16 is adapted to the guide rod 12, the moving slider 14 will move along the axial direction of the long screw 11. According to the wind direction and the stability requirements of the work platform, by controlling the rotation direction and speed of the driving motor 13, the position of the moving slider 14 in the side slide groove 10 is accurately adjusted, which will drive the counterweight box 17 and the counterweight block 20 therein to move, thereby changing the center of gravity position of the entire device to adapt to different wind directions and work requirements, and achieve the adaptive stability of the aerial work platform facing different wind directions in the air.
