[0002] my country is a mountainous country. The mountainous area accounts for 69.4% of the country's total land area, and the mountainous population accounts for more than 50% of the country's total population.

[0003] With the acceleration of construction in mountainous areas, the ecological environment has been damaged, and landslides in mountainous areas have become increasingly serious. Landslides are the phenomenon that rock or soil on a slope slides downward along a certain weak surface (or weak zone) under the action of gravity. Landslides often cause huge losses to industrial and agricultural production as well as people's lives and property, and some even bring devastating disasters.

[0038] Preferably, the warning part also includes a telescopic rod 18 and a mounting plate 5; one end of the telescopic rod 18 is arranged on the box body 3, and the other end thereof is connected to the mounting plate 5; the elastic member 4 is sleeved on the telescopic rod 18 and its two ends are respectively connected to the mounting plate 5 and the inner wall of the box body 3, and the central axes of the elastic member 4 and the telescopic rod 18 are kept in the same straight line during installation; the sliding member B is arranged on the mounting plate 5, and the movement direction of the elastic member 4 is always in the same straight line with the starting block 7, the alarm button 8, the mounting plate 5 and the sliding member B during movement.

[0039] Further preferably, the telescopic rod 18 includes a tube body and a rod body; the first end of the tube body is fixedly connected to the inner wall of the box body 3; the second end of the tube body is sleeved on the first end of the rod body so that the tube body and the rod body can slide relative to each other to adjust the length of the telescopic rod 18; the second end of the rod body is connected to the mounting plate 5, and the cooperation between the tube body and the rod body enables the telescopic rod 18 to be adjusted in length in the same direction as the extension and contraction direction of the elastic member 4, thereby ensuring that the telescopic rod 18 connected to the mounting plate 5 and the elastic member 4 sleeved on the telescopic rod 18 maintain consistent movement directions.

[0040] In this embodiment, preferably, the sliding member A and the sliding member B are both provided with grooves in contact with the monitoring rope 2. The sliding member A and the sliding member B are in sliding contact with the monitoring rope 2 through the grooves, and the monitoring rope will not separate from the sliding member A and the sliding member B.

[0043] Preferably, the response mechanism in this embodiment includes a power source 9 and a responder 10. The power source 9 is connected to the alarm button 8 by wireless or wired connection and is arranged on the housing 3. When a landslide is detected, the alarm button 8 is subjected to pressure from the start block 7 so that the alarm button (8) is connected to the power source 9 by wire, thereby controlling the power source 9 to supply power to the responder 10 to realize an alarm response. The responder 10 is connected to the power source 9 and is arranged on the housing 3 and / or the monitoring rope 2. When a landslide occurs, the power source 9 supplies power to the responder 10. When no landslide occurs, the power source 9 disconnects the power supply to the responder 10, thereby realizing all-weather monitoring of the landslide phenomenon by the monitoring device.

[0044] The specific implementation is as follows:

[0045] Installation work:

[0046] 1. Select the slope distance to be monitored, fix two sets of fixing parts 1 on the selected slope (i.e. the installation ground 20) (the two sets of fixing parts 1 are arranged in the vertical direction), and select the placement position of the box 3 (generally, the middle position of the two sets of fixing parts 1 is selected);

[0047] 2. One end of the monitoring rope is fixed on a set of fixing parts 1, and the other end is wrapped around the column and then passes through the through hole 11 on one side of the box 3 to enter the box, bypass the sliding parts A, sliding parts B, and sliding parts A, and then exit the box through the through hole 11 on the other side of the box 3, wrap around the column, and then fix it on another set of fixing parts 1. (The column can be inserted into the through hole without affecting the movement of the monitoring rope)

[0048] When the monitoring device detects a landslide:

[0049] A group of fixing parts 1 arranged on the slope move with the rock and soil on the slope, and the monitoring rope 2 connected to the fixing parts 1 is immediately tightened (the tension increases). The sliding part B in contact with the monitoring rope 2 drives the starting block 7 to move in the direction of the alarm button 8 under the action of the tension of the monitoring rope 2 until the starting block 7 contacts the alarm button 8. The power source 9 connected to the alarm button 8 supplies power to the responder 10 (alarm) to realize the alarm.

[0050] When no landslide occurs, the tension of the monitoring rope does not increase, the start block 7 does not contact the alarm button 8, and no alarm is sounded.

[0051] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
