s1: when the device is used, the rotating shaft (3) and the inserting rod (6) are respectively arranged in the first supporting plate (201) and the second supporting plate (202), then the positioning rods (203) on the two sides of the supporting plates are embedded into the positioning holes (204) of the supporting rods (2), the end parts of the supporting rods (2) and the small gears (301) are arranged in the cavity (5) formed by the first mounting seat (101) and the second mounting seat (102) in a surrounding mode, the bolts (104) are used for connecting the lug plates (103) on the outer sides of the first mounting seat (101) and the second mounting seat (102), the mounting of the protective fence is completed, the inserting rod (6) is inserted into the ground, and the device is fixed on the ground;
s2: when the weather is strong wind, the action force of strong wind on the protection plate (4) is applied, the protection plate (4) is stressed to drive the rotating shaft (3) to rotate, the protection plate (4) is parallel to the wind invasion direction after rotating, the impact force of the wind on the protection plate (4) is reduced, the action force applied to the device is reduced, the device is prevented from toppling, the pinion (301) and the rack plate (502) can be driven to be meshed in the rotating process of the rotating shaft (3) along with the protection plate (4), the rack plate (502) slides in the cavity (5), the first elastic element (501) is stretched, after the strong wind is over, the first elastic element (501) recovers and pulls the rack plate (502) to move back, the pinion (301) rotates, the rotating shaft (3) drives the protection plate (4) to recover the original position, the worker can conveniently watch the warning words on the protection plate (4), and the warning effect of the device is improved;
s3: in the process that the rotating shaft (3) rotates along with the protection plate (4), the moving pipe (7) sleeved at the bottom of the rotating shaft (3) can rotate along with the rotating shaft (3), so that the moving pipe (7) drives the threaded rod (8) to rotate, the threaded rod (8) is in threaded connection with the inner part of the inserted rod (6), the threaded rod (8) moves downwards, the first piston (6021) moves downwards in the second groove (602) and extrudes air flow in the second groove (602), the second groove (602) is communicated with the third groove (603), the air flow extrudes the second piston (6031) in the third groove (603), the second piston (6031) drives the sliding rod (6032) to move in the third groove (603) and the fourth groove (604), the second elastic element (6033) is compressed, the sliding rod (6032) drives the stop rod (6041) to move out of the inserted rod (6), the effect of limiting the inserted rod (6) is achieved, and the situation that the inserted rod (6) moves out of the ground due to the influence of wind power on the device is avoided, the ground gripping effect of the device is improved.
