Technical Field

[0001] This utility model relates to the field of landslide prevention and control, specifically to a landslide data acquisition device. Background Technology

[0002] Currently, landslide data collection devices are typically fixed in place, often resulting in a small collection area and limited data due to height or angle limitations. This makes the subsequent design of drainage ditches heavily reliant on the experience of designers, requiring extensive manual operation. Optimization design necessitates starting from the very first step, making the optimization process extremely difficult, time-consuming, and labor-intensive. Changing the collection location also necessitates reinstalling the collection device, which is similarly time-consuming and labor-intensive. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Furthermore, the connector has a hinge hole and a connecting hole. The hinge hole is located on the left and right sides of the connector.

[0008] Furthermore, the left telescopic support rod and the right telescopic support rod are each provided with a handle.

[0021] like Figure 1 and Figure 3As shown, a landslide data acquisition device includes a base 1, a front lifting hinge 2, a rear lifting hinge 3, a left telescopic support rod 4, a right telescopic support rod 5, a moving platform 6, and a data collection box 7 equipped with a data collector. The base 1 has two fixing blocks 8 at its bottom, which are buried underground. The burial of the fixing blocks 8 makes the base 1 more stable and improves the accuracy of the data. The fixing blocks 8 are located at the front and rear ends of the base 1. The tops of the front lifting hinge 2 and the rear lifting hinge 3 are respectively hinged to the moving platform 6, and the bottoms of the front lifting hinge 2 and the rear lifting hinge 3 are respectively hinged to the moving platform 6. On the base 1, the front lifting hinge 2 and the rear lifting hinge 3 are connected by a long bolt 9. When the technician controls the long bolt 9 to rotate clockwise, the hinge angle increases, and the moving platform 6 moves upward; when the long bolt 9 is controlled to rotate counterclockwise, the hinge angle decreases, and the moving platform 6 moves downward. The tops of the left telescopic support rod 4 and the right telescopic support rod 5 are respectively hinged to the moving platform 6, and the bottoms of the left telescopic support rod 4 and the right telescopic support rod 5 are respectively hinged to the base 1. Each of the left telescopic support rod 4 and the right telescopic support rod 5 has a handle and serves as a shock absorber. The data collection box 7 is connected to the moving platform 6 via a rotating component. The shock absorber makes the moving platform 6 more stable during lifting, improves the accuracy of the collected data, reduces the shear force of the long bolt 9, and extends the service life of the long bolt 9.

[0022] like Figure 2 As shown, the front lifting hinge 2 and the rear lifting hinge 3 have the same structure, both including a first body 21, a second body 22, and a connecting member 23; the first body 21 and the second body 22 are hinged together by the connecting member 23; the top end of the first body 21 is hinged to the moving platform 6, and the bottom end of the second body 22 is hinged to the base 1. As the technician controls the rotation of the long bolt 9, the first body 21 and the second body 22 will rotate relative to each other, thereby changing the distance between the upper end of the first body 21 and the lower end of the second body 22, achieving the purpose of raising or lowering the moving platform 6.

[0023] like Figure 4 As shown, the connector 23 has a hinge hole 231 and a connecting hole 232. The hinge holes 231 are located on the left and right sides of the connector 23, and the two hinge holes 231 are not connected to the connecting hole 232. Connectors 23 are respectively installed in the hinge holes 231 to facilitate relative rotation between the first body 21 and the second body 22. The hinge shaft passes through the first body 21 and the second body 22 in sequence and connects to the hinge holes 231, allowing the first body 21 and the second body 22 to rotate relative to each other. The connecting hole 232 has a thread, and a long bolt 9 is connected in the connecting hole 232. The connecting hole 232 passes through the connector 23 from front to back, and the long bolt 9 passes through the connecting hole 232. When the long thread rotates, the connector 23, under the action of the thread, causes the front lifting hinge 2 and the rear lifting hinge 3 to rotate relative to each other, ultimately realizing the raising or lowering of the moving platform 6.

[0024] like Figure 6 As shown, the base 1 includes a first support 11 and two auxiliary support 12, which are symmetrically hinged to the left and right sides of the first support 11. The bottoms of the front lifting hinge 2 and the rear lifting hinge 3 are hinged to the first support 11, the bottom of the left telescopic support rod 4 is hinged to the left auxiliary support 12, and the bottom of the right telescopic support rod 5 is hinged to the right auxiliary support 12. Hinge seats 13 are provided on both the left and right sides of the first support 11, and the auxiliary support 12 are respectively hinged to the hinge seats 13.

[0025] like Figure 5 As shown, the rotating component includes a rotating rod 10, a data collection box 7 connected to the rotating rod 10, and a worm gear reducer 14 connected to the bottom of the rotating rod 10. The worm gear reducer 14 is connected to the moving platform 6. The rotating rod 10 rotates under the action of the worm gear reducer 14, enabling the data collector to collect data in 360°, making the data more comprehensive.

[0026] After data is collected by the data processor in the data collection box, it is converted into data that is easy for technicians to observe and use. The data collector sends the collected data to point cloud data processing software, which is connected to the GIS processor. The data collector is equipped with a LiDAR system and can acquire landslide tilt images and point cloud data. The point cloud data processing software processes the image data collected by the data collector to obtain a digital orthophoto (DOM). The point cloud data processing software uses Contextcapture software. Then, TerraSolid is used for point cloud filtering and classification to remove surface vegetation and generate a high-precision digital elevation model (DEM). Based on the generated high-precision digital elevation model (DEM), the GIS processor uses the hydrological analysis functions of GIS, such as depression filling, flow direction, flow rate, and watershed, combined with raster extraction function, to obtain the rainwater flow path and catchment area. After conducting an on-site investigation of the landslide, technicians determined the landslide's extent and deformation characteristics. Water-repellent zones (areas where rainwater is prevented from converging and infiltrating) were established to address seepage channels such as cracks and cavities. Subsequently, using digital orthophotos, the rainwater flow path and catchment area were optimized within the GIS system. The key to optimization was avoiding flow paths passing through these water-repellent zones. The rainwater flow path, along with drainage ditches and catchment areas, was imported into the stormwater simulation software SWMM to establish a surface drainage model. The rainfall simulation process was determined based on the local storm intensity formula. Finally, in SWMM, based on the established surface drainage model, rainfall simulation was conducted using a design storm time series as the simulation condition. During the simulation, the layout and cross-sectional dimensions of the drainage ditches were adjusted according to the amount of infiltration within the landslide area. The simulation was repeated until the minimum infiltration within the landslide area was achieved, resulting in the most reasonable drainage system design.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
