[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0042] Example 1, please refer to Figure 1 As shown, the present invention is a monitoring device for soil landslides, including a landslide detection mechanism installed on a slope or other location prone to landslides, that is, the landslide detection mechanism provided by the present invention is installed at the detection location; at the same time, the landslide detection mechanism is communicatively connected with a monitoring center.

[0043] In order to facilitate the detection of landslide conditions at a detection location, the present invention provides a landslide detection mechanism comprising several detection modules A and a detection module B connected to the detection module A; the detection module A comprises a first structure 1a installed at the location where the landslide occurs at the detection location, and a second structure 1b installed below the location where the landslide occurs at the detection location, that is, the second structure 1b is actually installed at a location where landslides are not likely to occur.

[0044] Specifically, the first structure 1a provided by the present invention includes a mounting frame A and a cylinder A1 mounted on the mounting frame A, and the second structure 1b includes a mounting frame B and a cylinder B2 mounted on the mounting frame B, and the cylinder B2 and the cylinder A1 are connected through a hose A100a. Figure 11-14The bottom side surface of the cylinder B2 is connected to a movable plate A231 which slides sealingly along the inner wall of the cylinder B2 through a spring A23, and a ceramic column 232 is connected to the upper surface of the movable plate A231; a circular plate 27 which seals with the inner wall of the cylinder B2 is arranged in the cylinder B2 above the movable plate A231, and an opening A270 for the ceramic column 232 to pass through is arranged at the center of the circular plate 27, and a sealing sleeve 271 which cooperates with the ceramic column 232 is arranged in the opening A270; a groove 233 which is opened along the axial direction of the ceramic column 232 is arranged on the top peripheral side wall of the ceramic column 232; a drainage port 28 is opened on the side wall of the cylinder B2 above the circular plate 27.

[0045] Specifically, the detection module B includes a detection box 1c with a liquid level sensor disposed therein, and a plurality of hoses B100b are disposed on the top of the detection box 1c, and the ends of the hoses B100b are connected to the drain port 28 of the cylinder B2.

[0046] In combination with the above-mentioned first structure 1a, second structure 1b and detection box 1c, when in use, water is injected into body B2 and cylinder A1. At this time, under the cooperation of water pressure and spring A23, ceramic column 232 and sealing sleeve 271 are sealed and matched; when cylinder A1 drops in height, under the cooperation of water pressure and spring A23, movable plate A231 moves upward to groove 233 and seal sleeve 271; thus, when landslide occurs, the first structure 1a slides down from the installation position. That is, at this time, the installation height difference between the first structure 1a and the second structure 1b is reduced, and the water pressure on the movable plate A231 is reduced. At this time, the movable plate A231 moves upward under the action of the spring A23, and the groove 233 is inserted into the sealing sleeve 271. At this time, the water in the cylinder B2 will be discharged from the groove 233 into the drain port 28, and discharged into the detection box 1c through the hose B100b. That is, when the liquid level sensor detects the liquid level signal, the landslide information is sent to the monitoring center through the controller connected thereto.

[0047] Example 2. On the basis of Example 1, it is also necessary to know that when assembling the first structure 1a and the second structure 1b, water is injected into the cylinder A1 until the cylinder B2 is filled with water. At this time, due to the different height differences between the first structure 1a and the second structure 1b, the different water pressures cause the positions of the grooves 233 at the ends of the ceramic columns 232 to be different. Therefore, when in use, it is necessary to control the circular plate 27 to move up and down to meet actual usage requirements.

[0048] Specifically, Figure 13-14A support plate 25 is installed on the inner wall of the cylinder B2 above the movable plate A231, and a circular plate 27 sliding along the inner wall of the cylinder B2 is connected to the upper surface of the support plate 25 through a spring B26; a porous cover plate 24 is arranged on the top of the cylinder B2, and an adjusting bolt A241 is threadedly connected to the porous cover plate 24; a connecting frame 272 is connected to the upper surface of the circular plate 27, and the end of the adjusting bolt A241 abuts on the connecting frame 272, and a limiting block 234 that can abut against the upper surface of the circular plate 27 is arranged on the top of the ceramic column 232; after the first structure 1a and the second structure 1b are assembled and water is injected into the cylinder A1 at the same time until the cylinder B2 is filled with water, the adjusting bolt A241 is rotated until the circular plate 27 moves upward along the inner wall of the cylinder A1 under the action of the spring B26 until the limiting block 234 abuts against the upper surface of the circular plate 27, that is, no water is discharged from the drain port 28 at this time, indicating that the adjusting bolt A241 is rotated and adjusted to the desired position.

[0049] At the same time, in order to facilitate the overall installation, an opening B251 for the ceramic column 232 to pass through is provided at the center of the support plate 25; a limiting ring A241 is provided on the inner wall of the cylinder B2 between the movable plate A231 and the support plate 25; a first connector 22 connected to the hose A100a is provided on the inner wall of the cylinder B2 above the limiting ring A241; and a second connector 12 connected to the hose A100a is provided on the bottom inner wall of the cylinder A1.

When in use, after the first structure 1a, the second structure 1b and the detection box 1c are assembled, the L-shaped overflow pipe 13 is used to achieve that after the cylinder A1 and the cylinder B2 are filled with water, the water pressure on the movable plate A231 is kept stable.

[0052] Specifically, a bottom plate 31 is provided at the bottom of the water tank 3 , and a supporting leg 32 is connected to the bottom plate 31 .
