[0029] When the soil is unstable and a small-scale soil landslide occurs, a plurality of elastic ropes 11 are arranged to form a barrier net, which can intercept and slow down the small-scale soil landslide.

[0030] Example 2

[0031] like Figure 1-4 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that the fixing mechanism includes a fixing tube 6, the fixing tube 6 is vertically arranged, a driving motor 7 is arranged on the side of the fixing tube 6 close to the driving rod 10, the driving motor 7 is fixedly connected to the fixing tube 6, and the power output end 8 of the driving motor 7 is fixedly connected to the end of the driving rod 10.

[0032] The fixing mechanism also includes a fixing seat 12, which is arranged on the top of the fixing tube 6, and the fixing seat 12 is fixedly connected to the top of the fixing tube 6; a guide seat 14 is arranged on the upper part of the fixing tube 6, and the guide seat 14 is located below the fixing seat 12, and the edge of the guide seat 14 is fixedly connected to the inner wall of the fixing tube 6; a plurality of buffer pressure rods 15 are arranged through the guide seat 14, and the buffer pressure rods 15 are slidably connected to the guide seat 14, and a buffer spring 13 is arranged above the buffer pressure rod 15, and the lower end of the buffer spring 13 is fixedly connected to the upper end of the buffer pressure rod 15, and the upper end of the buffer spring 13 is fixedly connected to the fixing seat 12; a guide rod 5 is arranged through the center of the guide seat 14, and the guide rod 5 is slidably connected to the guide seat 14, and the upper end of the guide rod 5 passes through the fixing seat 12, and the upper end of the guide rod 5 slides with the fixing seat 12, and the upper end of the guide rod 5 is fixed to the end of the wire rope 1, and a sliding seat 4 is arranged below the guide seat 14, and the sliding seat 4 is slidably connected to the inner wall of the fixing tube 6, and the lower end of the guide rod 5 passes through the sliding seat 4, and the guide rod 5 is fixed to the sliding seat 4. The fixing mechanism also includes a driving ball 3, which is located between the guide seat 14 and the sliding seat 4. A plurality of grooves 16 are provided at the bottom of the guide seat 14, and the lower end of the buffer pressure rod 15 is located in the groove 16. The fixing mechanism also includes a controller 18, which is located above the buffer pressure rod 15, passes through the fixing seat 12, is fixedly connected to the fixing seat 12, and a self-reset control button 21 is provided at the bottom of the controller 18. An arc tube 2 is provided above the fixing tube 6, and the steel wire rope 1 is located in the arc tube 2, and the lower end of the arc tube 2 is fixedly connected to the top of the fixing tube 6. The arc tube 2 is made of stainless steel.

[0033] The fixed pipe 6 is fixed in the soil, so that the steel wire rope 1, the elastic rope 11, and the driving rod 10 form a blocking net in the middle or bottom of the soil slope. When a small-scale soil landslide impacts the elastic rope 11, the elastic rope 11 pulls the guide rod 5 upward through the steel wire rope 1, and the guide rod 5 pulls the sliding seat 4 upward, and the sliding seat 4 drives the driving ball 3 to move upward synchronously, so that the driving ball 3 randomly enters a groove 16 to press the lower end of the buffer pressure rod 15, so that the buffer pressure rod 15 moves upward to press the buffer spring 13, thereby achieving a buffering effect.

[0034] Since the driving ball 3 can move freely in the fixing tube 6, each time the soil impacts the elastic rope 11, the driving ball 3 can randomly enter different grooves 16, so that different buffer springs 13 are pressed each time, thereby increasing the service life of each buffer spring 13 and maintaining the buffering effect.

[0035] Example 3

[0036] like Figure 1-4As shown, when other parts are the same as those in Example 2, the difference between this embodiment and Example 2 is that the controller 18 is wirelessly connected to the drive motor 7, and the drive motor 7 is started when the self-reset control button 21 is pressed, and the drive motor 7 is turned off when the self-reset control button 21 is not pressed. The controller 18 is also wirelessly connected to an alarm, and the alarm sounds when the self-reset control button 21 is pressed.

[0037] When the buffer pressure rod 15 moves upward, the self-reset control button 21 is pressed, so that the controller 18 controls the drive motor 7 to start, so that the drive motor 7 drives the drive rod 10 to rotate, so that the drive rod 10 winds the elastic rope 11, and the elastic rope 11 gradually becomes thinner, so that the gap between the two adjacent elastic ropes 11 becomes larger, so that the soil blocked by the elastic rope 11 slowly slides through the gap between the two adjacent elastic ropes 11, that is, the effect of blocking small-scale soil landslides is achieved, and too much soil is avoided in front of the device.

[0038] At the same time, the controller 18 controls the alarm to sound an alarm, reminding the staff that the soil is unstable and a small-scale landslide may occur.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
