Description

Technical Field

[0001] This utility model relates to a binary erosion and loss device for karst slope soil with adjustable porosity, belonging to the field of soil erosion experiments. Background Technology

[0002] A soil trough is an important experimental device used to simulate soil environments for agricultural machinery, geotechnical testing, and ecological research. In agricultural machinery research, soil troughs can simulate the operating performance of agricultural machinery under different soil conditions, providing experimental data for the design and optimization of agricultural machinery. In geotechnical testing, soil troughs can be used to study soil mechanical properties, water transport, and other related aspects. In ecological research, soil troughs can simulate natural soil ecosystems to study plant growth, soil microbial activity, and other related activities.

[0003] Existing soil troughs typically consist of a trough body, a drive system, and a testing system. The trough body is generally made of steel or concrete and has a certain length and width to meet the needs of different experiments. Soil is laid inside the trough to simulate the actual soil environment. The drive system is usually driven by an electric motor, which moves the experimental object within the trough via a transmission device. The drive system can achieve different speed and acceleration controls to simulate different operating conditions. The testing system includes various sensors and data acquisition devices used to measure various parameters during the experiment, such as force, displacement, velocity, and soil moisture. The testing system can collect and record experimental data in real time, providing a basis for subsequent analysis and research.

[0004] However, existing earth trench implementation schemes have some shortcomings, mainly in the following aspects:

[0005] 1. The simulated soil environment is inaccurate.

[0006] Limited soil texture: Existing soil troughs can only simulate a limited number of soil textures, making it difficult to comprehensively cover various actual soil conditions, resulting in insufficient universality of experimental results; Inaccurate humidity control: Limited ability to regulate soil humidity, unable to accurately simulate soil conditions under different humidity conditions, affecting experiments sensitive to moisture; Difficulty in adjusting compaction: Difficulty in flexibly adjusting soil compaction, unable to meet the needs of experiments on soils with different compaction degrees.

[0007] 2. The reliability and accuracy of the experiment are not good.

[0008] Significant boundary effects: The boundaries of the soil trough significantly interfere with the experiment, causing deviations between the behavior of the experimental subjects and the actual situation, thus reducing the reliability of the experimental data; Unstable experimental conditions: The experiment is greatly affected by external environmental factors, such as temperature changes and light intensity, making it difficult to maintain stable experimental conditions and resulting in large fluctuations in experimental results; Limited measurement accuracy: The sensors and data acquisition equipment are not accurate enough, making it impossible to accurately measure some key parameters, thus affecting the accuracy of the experimental results.

[0009] 3. Low experimental efficiency

[0010] Soil replacement is cumbersome: The process of replacing soil is complicated and time-consuming, which reduces the efficiency of experiments and limits the continuity and diversity of experiments; Single function: Most soil troughs can only be used for specific types of experiments, lacking multi-functional integration and failing to meet diverse experimental needs.

[0011] 4. Insufficient consideration of energy conservation

[0012] Water waste: Due to the lack of an effective water recycling system, water was wasted seriously during the experiment.

[0013] With continuous technological advancements, the design requirements for soil troughs are becoming increasingly stringent. More precise adjustment of soil porosity is needed to improve the reliability and accuracy of experiments; simultaneously, higher levels of automation are required to enhance experimental efficiency and reduce costs. Furthermore, environmental protection and sustainable development demands are driving soil trough design to place greater emphasis on energy conservation, environmental friendliness, and resource recycling. Summary of the Invention

[0014] This invention provides a binary soil erosion and loss device for karst slopes that can precisely adjust porosity, in order to solve the problems of traditional soil troughs having difficulty in accurately adjusting soil porosity and low automation.

[0015] To address the aforementioned issues, a dual-evolution soil erosion and loss device for karst slopes with precisely adjustable porosity is proposed. The device includes a soil trough support, a soil trough body, and a pulley lifting system. The soil trough body is placed on the soil trough support, and the bottom of the downstream end of the soil trough body is hinged to the soil trough support. The pulley lifting system lifts the upstream end of the soil trough body by pulling the upstream end of the soil trough body with a traction rope equipped with pulleys.

[0016] In the aforementioned device, the pulley lifting system includes a bracket fixed to the indoor roof, a pulley installed under the bracket, one end of the traction rope passing over the pulley and fixed to the hook, the hook being hooked on the upstream end of the soil trough body, and the other end of the traction rope being the control end. The upstream end of the soil trough body is lifted by pulling the other end of the traction rope, the soil trough body is adjusted to the required angle, and then the other end of the traction rope is fixed.

[0017] In the aforementioned device, the upstream end of the trough body is a water trough, and the remaining troughs are soil troughs. There is an inclined partition between the water trough and the soil trough, and the middle of the partition has a slot in the horizontal direction.

[0018] In the aforementioned device, the bottom plate of the soil trough is a slit plate with distributed openings and a porosity of 5%. Below the bottom plate, there is also a collection trough with a planar dimension larger than the bottom plate for collecting lost soil.

[0019] In the aforementioned device, the lower surface of the base plate is also tightly fitted with an adjustment plate that has the same hole distribution and hole size as the base plate. The bottom of the base plate is provided with a slot, and the adjustment plate moves along the slot to adjust the overlap of the holes on the base plate and the adjustment plate, thereby adjusting the overall porosity of the base plate.

[0020] Compared with existing technologies, this invention employs a double-layer fractured plate structure and controls the amount of overlap to achieve precise control over the overall base plate fracture degree. The water trough design uses a gentle slope to effectively reduce the scouring force of water flow, thus protecting the structure from erosion. It abandons the traditional method of adjusting the water trough angle by screwing or increasing the height, instead using a pulley system suspended from the roof for precise adjustment. Through the pulley device, the soil trough and water trough can be easily adjusted to any suitable angle, and accurate measurements can be made by placing a protractor at the bottom to ensure angle accuracy. During adjustment, the bottom of the pulley can be equipped with hook locks for quick fixation after adjustment to the ideal angle, ensuring structural stability. Furthermore, a dedicated track is installed on the roof for the pulleys, allowing them to move smoothly along the track, greatly facilitating the adjustment process. To enhance system safety, two additional auxiliary pulleys are added to the roof to provide extra support and protection. This improvement not only enhances the flexibility and accuracy of adjustment but also strengthens the overall structural safety and durability. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Example

[0027] See attached document Figures 1 to 4 This embodiment improves the dual erosion and loss device for karst slope soil, specifically including a soil trough support 1, a soil trough body 2, and a pulley lifting system 3. The soil trough body 2 is placed on the soil trough support 1, and the bottom of the downstream end of the soil trough body 2 is hinged to the soil trough support 1. The pulley lifting system 3 pulls the upstream end of the soil trough body 2 by a traction rope 33 equipped with pulleys 32 to lift the upstream end of the soil trough body 2.

[0028] Specifically, the pulley lifting system 3 includes a bracket 31 fixed to the indoor roof, a pulley 32 installed under the bracket 31, one end of a traction rope 33 passing around the pulley 32 and fixed to a hook 34, the hook 34 being hooked onto the upstream end of the earth trough body 2, and the other end of the traction rope 33 being the control end. By pulling the other end of the traction rope 33, the upstream end of the earth trough body 2 is lifted, the earth trough body 2 is adjusted to the required angle, and then the other end of the traction rope 33 is fixed. The trough body 2 has a water trough 21 at the upstream end, and the remaining troughs are earth troughs 22. There is an inclined partition 23 between the water trough 21 and the earth trough 22, and the middle of the partition 23 has a slot 24 opened in the horizontal direction.

[0029] The bottom plate 25 of the soil trough 22 is a perforated fissure plate with a porosity of 5%. Below the bottom plate 25, a collection trough 26 with a larger planar dimension than the bottom plate 25 is fixed for collecting lost soil. An adjusting plate 27 with the same perforation distribution and size as the bottom plate 25 is tightly fitted to the lower surface of the bottom plate 25. A slot 28 is provided at the bottom of the bottom plate 25. The adjusting plate 27 moves along the slot 28 to adjust the overlap between the bottom plate 25 and the perforations on the adjusting plate 27, thereby adjusting the overall porosity of the bottom plate 25. The porosity can be adjusted from 0% to 5%. Figure 4 As shown, a roller is mounted on the slot 28, and the adjusting plate 27 is horizontally mounted on the roller and rolls and moves horizontally. One end of the adjusting plate 27 is fixedly connected to the rack in the gear and rack drive mechanism 29. By turning the gear with a crank handle, the rack moves horizontally, thereby causing the adjusting plate 27 to move horizontally relative to the base plate 25. As shown in the figure, the gear and rocker combination and the transmission device can work together to allow the adjusting plate 27 (the second layer of the split plate) to make fine adjustments and slide horizontally, thereby achieving precise control over the overlap of the two layers of split plates. This ingenious sliding mechanism gives users the ability to flexibly adjust the size of the split according to actual engineering needs, so as to achieve fine control over the degree of splitting.

[0030] To further enhance the accuracy and convenience of the adjustment process, clear scale markings can be added to the outer side of the track of the gear rocker assembly. These markings not only provide users with an intuitive reference but also make the adjustment of the fracture density more precise and controllable. Users can easily set the fracture density based on these markings, whether to cope with varying geological conditions or to meet specific engineering standards. This design concept provides an efficient, precise, and user-friendly solution to adapt to the complex and ever-changing challenges of underground engineering, ensuring the stability and functionality of the fractured plate system and meeting high-standard engineering requirements.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
