[0031] Working principle: When in use, first, when a small amount of soil landslide occurs in the main body 2 of the slope, the soil on the surface of the main body 2 of the slope rolls toward one end of the rotating plate 401 due to gravity. Since the rotating plate 401 is initially vertical, a small amount of soil is blocked at one end by the rotating plate 401.

[0032] Secondly, when a landslide occurs at one end of the slope body 2, and a large amount of soil rolls down, the kinetic energy generated by the rolling of the large amount of soil hits one end of the rotating plate 401, and the impact force causes the rotating plate 401 to rotate, and the rotating plate 401 rotates to drive the rotating column 402 to rotate, and the rotating column 402 rotates the extrusion block 403 to rotate, and the extrusion block 403 rotates and squeezes the top end of one end of the sliding block 404, thereby driving the sliding block 404 to move downward, and the sliding block 404 moves downward and drives the first sliding plate 4041 to move, and the first elastic The spring 4043 is squeezed by force, the first sliding plate 4041 moves and drives the first rack 405 to move downward, the first rack 405 moves and drives the spur gear 406 to rotate, the spur gear 406 rotates and drives the second rack 407 to move upward, the second rack 407 moves and drives the second sliding plate 4071 to move, the second spring 4073 is squeezed by force, the second sliding plate 4071 moves and drives the moving rod 408 to move upward, the moving rod 408 moves and drives the protective plate 409 to move, and at this time the height of one end of the fixed seat 3 increases;

[0033] Finally, the initial state of the rotating plate 401 is vertical, which can block the small volume of soil sliding down the surface of the slope body 2, and preliminarily avoid the situation where the soil rolls down on the inclined surface of the slope body 2. At the same time, when a large volume of soil rolls down, the large volume of soil collides with one end of the rotating plate 401 to drive the rotating plate 401 to rotate.
