Description

Technical Field

[0001] The invention relates to the technical field of landslide geological disaster monitoring, in particular to a landslide geological disaster monitoring device. Background Art

[0002] Landslide refers to the phenomenon that the soil or rock on the slope slides downward as a whole or partially along a certain weak surface or weak zone under the action of gravity, affected by factors such as river scouring, groundwater activity, rainwater soaking, earthquakes and artificial slope cutting. More than 80% of landslides are caused by heavy rainfall, especially during heavy rain or some time after rain, when the soil is softened and soaked. In order to reduce the losses caused by landslides, a landslide geological disaster monitoring device will be used to monitor landslide disasters.

[0003] When using displacement sensors to monitor landslides, they are usually distributed in a point-like manner, which reduces the monitoring range of soil displacement and makes the monitoring less comprehensive. In addition, when monitoring landslides, only monitoring is carried out and corresponding delay measures cannot be taken to slow down the flow rate of soil, which makes it difficult to buy more time for rescue workers.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing landslide monitoring devices on the market, and even if they can be solved, they need to be solved through external tools, which cannot achieve the desired effect.

[0034] 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.

[0035] Example 1: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a landslide geological disaster monitoring device, comprising a main body mechanism 1, the main body mechanism 1 comprises two positioning boxes 11, the positioning boxes 11 are positioned at a non-soil position by bolts to ensure the stability of the positioning boxes 11 when a landslide occurs, the two positioning boxes 11 are arranged opposite to each other, and a sensing mechanism 2 is arranged between the two positioning boxes 11;

[0036] The sensing mechanism 2 includes a sensing unit 21 , which is disposed between the two positioning boxes 11 . The sensing unit 21 is used to directly transmit the thrust of the soil during landslide.

[0037] As a further limitation of the sensing mechanism 2 of the present invention, the sensing unit 21 includes a steel wire rope 2101, both ends of the steel wire rope 2101 are fixedly connected with sliding plates 2102, one side of the sliding plate 2102 is fixedly connected with a moving rod 2103, the inner cavity of the positioning box 11 is fixedly connected with a displacement sensor 2104, the output end of the displacement sensor 2104 is electrically connected to an external alarm device through an electric wire, one end of the moving rod 2103 penetrates into the inner cavity of the positioning box 11 and is fixedly connected to the displacement end of the displacement sensor 2104, the surface of the moving rod 2103 is slidably connected to the inner wall of the positioning box 11, a plurality of positioning sleeves 2105 are fixedly connected to the surface of the steel wire rope 2101, and the plurality of positioning sleeves 2105 are equidistantly distributed on the surface of the steel wire rope 2101, and an L-shaped panel 2106 is provided on one side of the positioning sleeve 2105, and the L-shaped panel 21 An embedding groove 2107 is provided on the top of 06, and a clamping plate 2108 is provided in the inner cavity of the embedding groove 2107. The surface of the clamping plate 2108 is in contact with the inner cavity of the embedding groove 2107. The clamping plate 2108 is fixed to the L-shaped panel 2106 by bolts. Two positioning blocks 2109 are fixedly connected to the top of the clamping plate 2108. The inner cavities of the two positioning blocks 2109 are rotatably connected with a rotating column 2110. The surface of the rotating column 2110 is fixedly connected with a fitting plate 2111. One side of the two positioning blocks 2109 is fixedly connected with a cross bar 2112. One side of the cross bar 2112 is fixedly connected to the positioning sleeve 2105 by bolts. By setting the sensing unit 21, the sensing range of the displacement sensor 2104 can be increased, and the point distribution is converted into a strip distribution, thereby increasing the monitoring range of the landslide and increasing the accuracy and comprehensiveness of the landslide hazard monitoring.

[0038] A sliding hole 2113 is provided on one side of the positioning box 11, and the surface of the moving rod 2103 contacts the inner cavity of the sliding hole 2113. A limiting groove 2114 is provided on the inner top of the sliding hole 2113. The top of the moving rod 2103 is fixedly connected to a limiting block 2115, and the surface of the limiting block 2115 contacts the inner cavity of the limiting groove 2114. By setting the sliding hole 2113, the limiting groove 2114 and the limiting block 2115, sufficient space is provided for the movement of the moving rod 2103 on the inner wall of the positioning box 11, and the guidance of the moving trajectory of the moving rod 2103 is realized, thereby increasing the stability of the moving rod 2103 when moving.

[0039] The inner side of the positioning box 11 is fixedly connected with a first baffle 2116 and a second baffle 2117, the first baffle 2116 and the second baffle 2117 are staggered, the first baffle 2116 and the second baffle 2117 are used to block the sliding hole 2113, the surface of the moving rod 2103 is in contact with the surface of the first baffle 2116 and the second baffle 2117, the first baffle 2116 and the second baffle 2117 are both made of silicone material, and the inside of the first baffle 2116 and the second baffle 2117 are fixedly connected with soft magnetic strips; By setting the first baffle plate 2116 and the second baffle plate 2117 in an offset manner, the sliding hole 2113 can be shielded. With the help of the flexibility of the silicone, the position of the moving rod 2103 between the first baffle plate 2116 and the second baffle plate 2117 is in an open state, and the remaining position is in a fitted state. The magnetic adsorption at the connection between the first baffle plate 2116 and the second baffle plate 2117 is strengthened by the soft magnetic strip, which prevents rainwater from outside from entering the positioning box 11 through the sliding hole 2113, thereby protecting the inner cavity of the positioning box 11.

[0040] The specific implementation of this embodiment is as follows: when installing the device, the two positioning boxes 11 are symmetrically installed at the same height of the slope by fasteners such as bolts, and are installed in a non-soil position. An installation platform parallel to the slope can be poured with concrete to install the positioning boxes 11. This is a prior art and will not be elaborated on in detail. It is ensured that when a landslide occurs, the displacement sensor 2104 in the positioning box 11 can monitor the landslide normally. Subsequently, a pit of appropriate depth is dug on the slope between the two positioning boxes 11, and the L-shaped panel 2106 is horizontally embedded in the soil layer. Subsequently, the card plate 2108 is inserted into the embedding groove 2107, and the card plate 2108 is positioned in the inner cavity of the embedding groove 2107 by bolts. Subsequently, the bonding plate 2111 is rotated, and the bonding plate 2111 is rotated on the inner wall of the positioning block 2109 by the rotating column 2110 to adjust the angle so that one side of the bonding plate 2111 is aligned with the slope surface. The laminating plates 2111 are tightly fitted, and the limiting units 22 are used to limit the fitting plates 2111. Then, the same number of positioning sleeves 2105 are installed on the surface of the steel wire rope 2101 as the number of L-shaped panels 2106. The positioning sleeves 2105 are fixed to the corresponding cross bars 2112 by bolts. When a landslide occurs, the flow of soil pushes the L-shaped panels 2106 and the laminating plates 2111, thereby pushing the positioning blocks 2109, the cross bars 2112, the positioning sleeves 2105 and the steel wire rope 2101 to be displaced. The displacement of the steel wire rope 2101 drives the sliding plate 2102 and the moving rod 2103 to move. The movement of the moving rod 2103 causes the sliding end of the displacement sensor 2104 to move, thereby causing the displacement sensor 2104 to generate a value. The displacement sensor 2104 transmits the value to an external alarm device, and transmits the landslide danger to relevant personnel, thereby realizing the monitoring of the landslide condition.

[0041] Example 2: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a landslide geological disaster monitoring device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The sensing mechanism 2 also includes a limit unit 22, which is arranged inside the sensing unit 21. The limit unit 22 is used in conjunction with the sensing unit 21. The limit unit 22 is used to limit the rotation angle of the sensing unit 21.

[0042] As a further limitation of the sensing mechanism 2 of the present invention, the limiting unit 22 includes a receiving groove 2201, the receiving groove 2201 is opened at one end of the rotating column 2110, and the inner cavity of one of the positioning blocks 2109 is provided with three moving grooves 2202, and the inner cavity of the moving groove 2202 is slidably connected with a moving block 2203, and one side of the moving block 2203 is fixedly connected with a clamping block 2204, and the three clamping blocks 2204 are all located in the inner cavity of the receiving groove 2201, and the inner wall of one of the positioning blocks 2109 is threadedly connected with a screw 22 05. One end of the screw rod 2205 is fixedly connected with an extrusion column 2206, which is conical in shape. The surface of the extrusion column 2206 contacts the inner sides of the three clamping blocks 2204. One end of the screw rod 2205 is fixedly connected with a turning handle 2207. By setting a limit unit 22, the rotation angle of the bonding plate 2111 can be positioned, so that the bonding plate 2111 can be tightly attached to the surface of the slope, thereby increasing the stability of the bonding between the bonding plate 2111 and the slope surface, thereby increasing the accuracy of the landslide displacement monitoring results.

[0043] A first spring 2208 is fixedly connected to the inner wall of the movable groove 2202, one end of the first spring 2208 is fixedly connected to one side of the movable block 2203, and guide blocks 2209 are fixedly connected to both sides of the movable block 2203. Two guide grooves 2210 are relatively opened on the inner side of the movable groove 2202, and the surface of the guide block 2209 is in contact with the inner cavity of the guide groove 2210; by setting the first spring 2208, the guide block 2209 and the guide groove 2210, the elastic adjustment of the moving distance of the movable block 2203 in the inner cavity of the movable groove 2202 is realized, and the limiting and guiding of the moving distance of the movable block 2203 are realized, thereby increasing the stability of the movable block 2203 during movement, and the movable block 2203 can be reset after displacement through the reaction force of the first spring 2208.

[0044] The specific implementation method of this embodiment is as follows: after the rotation angle of the bonding plate 2111 is adjusted, that is, after the bonding plate 2111 is in close contact with the slope surface, the user rotates the handle 2207 to rotate the screw 2205 and drive the extrusion column 2206 to move toward the inner cavity formed by the three clamping blocks 2204. In the initial state, the first spring 2208 is in a non-compressed state. At this time, the three clamping blocks 2204 are in a non-contact state with the inner wall of the receiving groove 2201, thereby realizing the free rotation of the rotating column 2110. As the extrusion column 2206 is embedded, the three clamping blocks 2204 are squeezed and diffused. At this time, the clamping block 2204 is guided by the moving block 2203, the moving groove 2202, the guide block 2209 and the guide groove 2210, and the first spring 2208 is compressed at this time until the surfaces of the three clamping blocks 2204 are in close contact with the inner cavity of the receiving groove 2201, thereby realizing the limitation of the rotation angle of the rotating column 2110.

Here, the elastic coefficient of the second torsion spring 316 is greater than the elastic coefficient of the first torsion spring 312, thereby ensuring that the first sleeve 304 and the second sleeve 305 can be stably at the set rotation angle, and the limiting circular plate 317 is driven to rotate on the inner wall of the fixed cylinder 315 while the rotating shaft 314 rotates, thereby increasing the stability of the rotating shaft 314 when rotating.

[0049] A second spring 321 is fixedly connected to the inner wall of the first sleeve 304, one end of the second spring 321 is fixedly connected to one end of the second sleeve 305, and two shift blocks 322 are fixedly connected to the surface of the second sleeve 305, and the two shift blocks 322 are both slidably connected to the inner wall of the first sleeve 304; by setting the second spring 321 and the shift blocks 322 for use in coordination, the elastic adjustment of the moving distance of the second sleeve 305 in the inner cavity of the first sleeve 304 is achieved, and the guidance of the moving trajectory of the second sleeve 305 and the limitation of the moving distance are achieved through the shift blocks 322, thereby ensuring the stability of the displacement of the second sleeve 305 in the inner cavity of the first sleeve 304.

[0050] The specific implementation of this embodiment is as follows: when a landslide occurs, the sliding plate 2102 is pulled by the wire rope 2101 to produce displacement, driving the trigger rod 313 to push the special-shaped bar 318, causing the special-shaped bar 318 to rotate, so that the part of the special-shaped bar 318 that contacts the slot 320 is flipped upward, and the extrusion of the extension bar 319 is cancelled. The rotation of the special-shaped bar 318 is coordinated by the rotating shaft 314, the fixed cylinder 315, and the second torsion spring 316 to cause the special-shaped bar 318 to rotate. After the extension bar 319 loses the extrusion force, the reaction force of the first torsion spring 312 drives the sleeve 303, the first sleeve 304 and the second sleeve 305 to reset and rotate. At this time, the first sleeve 304 and the second sleeve 305 are in a contracted state, and the second spring 321 is in a compressed state. In the process of resetting and rotating, the guide rod 306 and the special-shaped slot 301 are connected. The arc segment contacts, when the guide rod 306 moves to the oblique line segment in the inner cavity of the special-shaped groove 301, the second spring 321 loses its compression force, and the reaction force of the second spring 321 drives the second sleeve 305 to extend outward in the inner cavity of the first sleeve 304. At this time, the second sleeve 305 is displaced and guided in the inner cavity of the first sleeve 304 by the shifting block 322. The movement of the second sleeve 305 drives the second positioning bar 308 and the filter screen 309 to move. The second positioning bar 308 drives the clamping rod 310 to move in the inner cavity of the clamping rail 311 while moving, thereby increasing the stability of the second positioning bar 308 during movement, until the guide rod 306 moves to the terminal of the special-shaped groove 301. At this time, the filter screen 309 is already in a fully expanded state and is at a certain tilt angle, which can intercept and delay the moving soil, thereby buying more time for rescue personnel.
