Description

Technical Field

[0001] The present invention relates to a dual-purpose soil trough technology for wind-water combined erosion, and particularly to an experimental device for a dual-purpose soil trough for wind-water combined erosion. Background Art

[0002] Wind-water combined erosion refers to the interaction between wind erosion and water erosion, which usually occurs in arid and semi-arid regions, such as the Loess Plateau, desertification areas, etc., causing soil degradation in local areas. Traditional research mostly uses single erosion to simulate the water erosion or wind erosion process, such as water tanks or wind tunnels, but the single erosion process cannot truly reflect the process of the interaction between wind and water in the natural environment. In recent years, with the improvement of the requirements for ecological restoration and soil erosion prevention and control, the combined erosion simulation technology has gradually become a research hotspot, and the technology development shows the integration of equipment, developing from single function to multi-physical field coupling, such as a dual-purpose soil trough with a switchable wind tunnel-water tank mode; data multi-dimensionalization: combining technologies such as 3D scanning and particle image velocimetry (PIV) to monitor the erosion process and soil particle movement in real time.

[0003] In the prior art:

[0004] One is to use experimental equipment such as a wind tunnel experimental system, an artificial rainfall simulation system, and a single erosion soil trough to simulate natural erosion conditions and quantify the processes of soil erosion, transportation, and deposition by wind and water dynamics.

[0005] The other is a multi-physical field coupling experimental device: integrating the wind field, water flow field, and terrain parameters through a mechanical structure and a control system to realize the dynamic reproduction of combined erosion.

[0006] Disadvantages of the prior art:

[0007] At present, in the wind-water erosion experiment, the rainfall and the wind tunnel are often single experimental scenarios, which can only meet the use under a single erosion scenario, cannot meet the combined use of the wind tunnel and rainfall at the same time, and cannot conduct wind-water combined erosion experiments in the same experimental device.

[0008] Currently, no patents related to a dual-purpose soil trough for wind-water combined erosion have been searched.

[0009] In view of this, the present invention is specifically proposed. Summary of the Invention

[0010] The object of the present invention is to provide an experimental device for a dual-purpose soil trough for wind-water combined erosion to solve the above technical problems existing in the prior art.

[0011] The object of the present invention is achieved by the following technical solutions:

[0012] The experimental device for a dual-purpose soil trough for wind-water combined erosion of the present invention includes a soil filling soil trough box 1, a stable soil trough bottom plate 4, and a soil trough support 6;

[0013] The upper edge of the filled soil trough box 1 is provided with a foldable soil trough baffle 2;

[0014] One end of the filled soil trough box 1 is provided with a card slot device 11 for a movable runoff collection baffle. A soil trough side baffle 13 is inserted into the card slot device 11. After the soil trough side baffle 13 is pulled out, different runoff collection devices 3 can be replaced and inserted.

[0029] The soil trough experimental device for combined wind and water erosion of the present invention includes a soil filling trough box 1, a stabilized soil trough bottom plate 4, and a soil trough support 6;

[0032] The whole filled soil trough box 1 is placed on a stable soil trough bottom plate 4.

[0036] In summary, the wind-water combined erosion dual-purpose soil trough experimental device of the embodiment of the present invention comprehensively and deeply explores the mechanism and process of wind-water combined erosion, and develops a dual-purpose soil trough that can simultaneously simulate wind erosion and water erosion and is convenient for operation and handling. This dual-purpose soil trough can not only simulate wind erosion conditions with different wind speeds in a wind tunnel environment, but also, in cooperation with a rainfall simulation device, achieve water erosion simulation with different rainfall intensities, providing key technical support for accurately revealing the law of wind-water combined erosion and formulating effective soil erosion prevention and control measures, and filling the technical gap in the field of wind-water combined erosion in existing research.

[0037] In traditional soil erosion research, wind erosion and water erosion are often studied separately using independent test devices. For example, the common runoff scouring test soil trough is mainly used for water erosion research, and its structural design focuses on receiving surface runoff generated by rainfall and collecting sediment. This kind of soil trough usually has fixed water retaining plates and water collection ports. Although it can better meet the needs of water erosion tests, due to its fixed structure, it is difficult to be transported to equipment such as wind tunnels for wind erosion simulation. At the same time, existing wind erosion test devices are also difficult to be directly used for water erosion tests. Therefore, the present invention proposes a wind-water combined erosion dual-purpose soil trough experimental device.

[0038] For multi-dimensional data measurement, the side wall of the soil trough box of the present invention changes the commonly used stainless steel baffle in the past and adopts transparent high-strength resin glass, which is paired with a high-speed camera and a laser scanner to capture the deformation of the soil surface, the expansion of cracks and the movement trajectory of particles in real time, construct a three-dimensional dynamic model of the erosion process, and monitor the erosion process and the movement of soil particles in real time.

[0039] In order to more clearly demonstrate the technical solutions provided by the present invention and the resulting technical effects, the following will describe in detail the embodiments provided by the present invention with specific examples.

[0040] As Figures 1 to 4 shown:

[0041] The present invention includes:

[0042] 1. An experimental soil tank device for both wind and water erosion, including a runoff collection device 3, a soil filling tank box 1, a stable soil tank bottom plate 4, and a soil tank support 6. One end baffle 13 of the soil filling tank box body 1 is detachable, and the runoff collection device can be replaced by itself according to the needs of wind erosion and water erosion. A turnable stainless steel baffle 2 is arranged around the upper end of the soil filling tank box body 1. The stable soil tank bottom plate 4 is provided with a slope regulator 8 and a slope gauge 7, and the slope can be adjusted.

[0043] 2. The experimental soil tank device for both wind and water erosion adopts a multi-physical field coupling simulation technology and a modular function expansion design, breaking through the limitation of single-environment simulation of traditional equipment and realizing full-condition coverage of the interaction between wind erosion and water erosion.

[0044] 3. The soil tank experimental device adopts a low-cost modular design and a combination of high-performance materials, which significantly improves the experimental monitoring accuracy and the service life of the equipment while ensuring the reliability of the basic functions.

[0045] The experimental soil tank device for both wind and water erosion of the present invention includes a detachable runoff port, a soil filling tank box, and a stable soil tank bottom plate. One end baffle of the soil filling tank box body is detachable, and the runoff collection device can be replaced by itself according to the needs of wind erosion and water erosion. A turnable stainless steel baffle is arranged around the upper end of the soil filling tank box body, which can be erected during rainfall to reduce water droplet splashing. The stable soil tank bottom plate is provided with a jack and a slope gauge, and the slope can be adjusted. The soil tank experimental device adopts a low-cost modular design and a combination of high-performance materials, which significantly improves the experimental monitoring accuracy and the service life of the equipment while ensuring the reliability of the basic functions. The support adopts a stainless steel material support frame, and the antioxidant ability is enhanced through surface passivation treatment. Combined with the truss mechanical configuration, it realizes high-load support while reducing its own weight, has excellent corrosion resistance and structural durability, and can adapt to long-term complex environment operations. The side wall of the soil tank box body is made of high-transparency and high-strength resin glass, which not only meets the visualization requirements during the experiment but also can withstand the lateral pressure of the soil and mechanical impact. The joint adopts a double waterproof design of silicone sealant and embedded card slot to ensure that there is no leakage during the long-term use of the box body.

[0046] Example 1

[0047] As Figure 1As shown in the figure, the dual-purpose soil tank for wind and water erosion includes a runoff collection device 3, a soil filling tank box 1, a stable soil tank bottom plate 4, and a soil tank support 6. A foldable soil tank baffle 2 is provided at the upper end of the soil filling tank box 1. A card slot device 11 for a movable runoff collection baffle is provided at one end of the soil filling tank box 1. The runoff collection device 3 can be replaced by pulling out the side baffle 13 of the soil tank. The soil filling tank box 1 is placed on the stable soil tank bottom plate 4 as a whole. The stable soil tank bottom plate 4 is connected to the soil tank support 6 through a slope adjustment shaft 5. A slope adjuster 8, a slope gauge 7, and wheels 9 are provided on the soil tank support 6. The control rotation ring 10 is located on one side of the slope adjuster 8 to achieve slope adjustment.

[0048] Working principle:

[0049] When the operator needs to adjust the slope height of the soil filling tank box 1, the operator can rotate the control rotation ring 10 to control the slope adjuster 8 to jack up the lower end of the soil filling tank box 1, making the soil filling tank box 1 present a certain inclination angle, which can be adjusted as needed within a certain range, expanding the applicability. During the wind erosion process, the soil filling tank box 1 can be used as a single whole in the wind tunnel. During the water erosion process, the foldable soil tank baffle 2 can be erected to reduce water droplet splashing. According to needs, the side baffle 13 of the soil tank can be pulled out to replace the runoff collection device 3 to achieve the runoff collection process. During the whole experimental process, the wheels 9 at the lower part of the support can make the device move more conveniently.
