Description

Technical Field

[0001] The utility model relates to the technical field of sand dune movement detection, in particular to a sand dune movement detection device. Background Art

[0002] Dune movement detection devices are mainly used to monitor the position changes of sand dunes in deserts or sandy surfaces, which is crucial for understanding the impact of factors such as wind erosion, desertification, land degradation and climate change on surface morphology. Such devices can help scientists, environmental managers and related researchers obtain accurate data on dune dynamics, thereby providing a scientific basis for preventing and controlling desertification, formulating ecological protection strategies and predicting natural disasters such as sandstorms.

[0003] Dune movement detection is usually carried out using remote sensing technology, ground laser scanning and global positioning system tracking. Ground laser scanning requires creating a high-precision three-dimensional ground model by emitting laser pulses and measuring the time it takes for the reflections to return. Repeated scanning can reveal tiny deformations and position shifts on the dune surface. At this time, a three-dimensional laser scanner and a tripod are needed to support it.

[0004] Since the geology of the sand dunes is relatively loose, simply using a tripod inserted into the sand dunes will result in a small contact area between the tripod and the sand dunes, which is not enough to improve the stability of the entire device and is prone to displacement during detection, thus affecting the accuracy of the detection. Utility Model Content

[0006] The utility model provides a sand dune migration detection device, comprising a support seat, a detection component is installed on the upper end of the support seat, a positioning rod with a hollow structure inside is arranged on the lower side of the support seat, a positioning piece is slidably connected inside the positioning rod, an auxiliary piece is slidably connected outside the positioning rod, the auxiliary piece comprises an annular sleeve, a symmetrical sliding block is arranged inside the annular sleeve, the sliding block is slidably connected to a first sliding groove opened on the outside of the positioning rod, two auxiliary rods are symmetrically arranged on the lower side of the annular sleeve, and when the positioning piece slides out of the positioning rod, the positioning piece fixes the auxiliary piece.

[0007] Preferably, the positioning member comprises a bidirectional screw rod rotatably disposed in the positioning rod, two ends of the bidirectional screw rod are respectively threadedly connected to two vertical plates, and a transverse insertion rod is disposed on the lower side of the vertical plate.

[0008] Preferably, the transverse insertion rod passes through the wall surface of the positioning rod and is slidably connected to the positioning rod.

[0009] Preferably, one end of the bidirectional screw is connected to a gear, and a second sliding groove is opened on one side of the positioning rod. A rack is slidably arranged in the second sliding groove, and the rack is meshed with the gear.

[0010] Preferably, the auxiliary rod is provided with an insertion hole, and when the annular sleeve drives the auxiliary rod to slide downward, the transverse insertion rod is inserted into the insertion hole.

[0011] Preferably, a plurality of hollow rods are hinged on the sides of the support seat, inner rods are slidably arranged inside the hollow rods, and the inner rods are fixed inside the hollow rods by bolts.

[0012] Preferably, the detection assembly includes a support rod slidably arranged inside the upper end of the positioning rod, a top plate is arranged at the upper end of the support rod, a ratchet is rotatably arranged on the top plate, a base is connected to the ratchet, and a laser instrument is installed on the base.

[0015] Compared with the prior art, the sand dune migration detection device provided in the embodiment of the utility model has the following advantages:

[0016] 1. The utility model fixes the entire measuring and detecting device by inserting the positioning rod into the sand dune, and uses the annular sleeve to slide the auxiliary rod downward. When the auxiliary rod is inserted into the sand dune, the auxiliary rod can increase the stability of the positioning rod and push the rack downward to mesh with the gear. The gear drives the bidirectional screw rod to rotate, so that the two vertical plates slide out of the positioning rod with the horizontal insertion rod. The horizontal insertion rod passes through the auxiliary rod and is laterally inserted into the sand dune, thereby not only further improving the stability of the entire device, but also preventing the auxiliary rod from slipping accidentally.

[0017] 2. The utility model enables the support rod to slide inside the positioning rod, so that the support rod moves upward with the top plate.
