The sequence of mechanical actions of the entire device:

(1) When the external wind is strong, and the wind direction is left or right facing or facing away from the satellite pot 28, the wind blows the windshield 23 to the pressure sensor 35, the moving spring 21 is stretched, and the pressing block 18 As the windshield 23 moves, the pressure sensor 35 is squeezed.

(2) The pressure sensor 35 receives pressure and sends a signal to the power motor 40. The power motor 40 is started. The power motor 40 drives the driving shaft 41 to rotate. The bottom rod 39 and the locking arc 37 rotate with the driving shaft 41. The cylindrical pin 38 follows the bottom rod. 39 rotation, 180 rotation of the cylindrical pin 38 can cause the hexagonal groove wheel 13 to rotate 60 degrees, and the windshield plate 23 and the satellite pot 28 rotate 60 degrees with the hexagonal groove wheel 13, and the satellite pot 28 and the windshield plate 23 are intermittent. Rotate until the satellite pot 28 turns to the side to the wind direction. The moving spring 21 is reset, driving the pressure block 18 and the windshield 23 away from the pressure sensor 35.
