Description

Technical Field

[0001] This invention relates to the field of geotechnical and geological engineering technology, specifically to an artificial rainfall and seepage device for simulating the dynamics of large-scale mountain disasters. Background Technology

[0002] Landslides and debris flows are widespread, frequent, and highly dangerous geological hazards, often caused by short-duration heavy rainfall or long-duration low-to-medium intensity rainfall. They tend to occur in clusters in areas with similar geological and topographical conditions, causing significant damage to residents' lives, property, and infrastructure. Due to the wide distribution of mountain hazards such as landslides and debris flows, detailed monitoring is difficult. This has led most researchers to rely on physical model experiments. However, current physical model experimental devices are typically small-scale and have limited functionalities, making it difficult to reflect real-world mountain hazard conditions. They also cannot meet the needs of simulating and studying prevention and control measures for large-scale, multi-scale mountain hazards under the combined effects of multiple factors, thus hindering the development of research and prevention of mountain hazards such as landslides and debris flows. Summary of the Invention

[0003] The embodiments of the present invention provide an artificial rainfall and seepage device for simulating the dynamics of large-scale mountain disasters, which can solve the problem that the current research on simulation and prevention measures for large-scale and multi-scale mountain disasters under the combined action of multiple factors is not possible.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0030] Please see Figure 1 , Figure 3 and Figure 4 In a first aspect, embodiments of this application provide an artificial rainfall and seepage device for simulating the dynamics of large-scale mountain disasters, including a material box with its bottom inclined and an openable gate on one side of the material box;

[0031] A water tank is located on the side of the material box away from the gate, and multiple rows of through holes are provided in the part of the water tank adjacent to the material box;

[0032] An artificial rainmaking mechanism is located above the material bin.

[0033] Understandably, the material bins are used to load materials and water. For large-scale mountain disaster dynamics experiments, the maximum material volume can reach 500 cubic meters at a time. Large transport vehicles transport materials along the winding mountain access road to the top platform and pile them in the material bins on the top platform. In addition, the impact of slope vegetation, retaining measures, slope reinforcement, etc. on soil stability can be assessed inside the material bins. Soil was stockpiled within a hopper environment, and different methods were used to reinforce and protect slopes. The impact of these methods on slope stability was thoroughly understood and analyzed. The role of slope vegetation was assessed: how vegetation on slopes affects soil stability. Plants play a positive role in slope stability by fixing soil with their roots, reducing soil erosion, and regulating surface water runoff. The effectiveness of retaining structures was examined and analyzed: the actual effects of various retaining structures in preventing soil slippage and maintaining slope stability were investigated. These structures enhance the overall stability of the soil by providing additional support or resistance. Slope reinforcement methods were evaluated: the degree to which different slope reinforcement techniques improve soil stability was assessed. These techniques achieve the purpose of slope reinforcement by improving the mechanical properties of the soil, increasing its shear strength, and enhancing its overall stability. In conclusion, through simulation experiments within the hopper, the effects of these methods and their specific impacts on soil stability can be more accurately understood. This is of great significance for the design, construction, and maintenance of slope engineering, and helps ensure the safety and stability of slope projects.

[0034] It is understandable that the water tank is a seepage device used to simulate large-scale mountain disaster dynamics experiments. The amount of seepage flow and the level of seepage water are controlled by controlling the water level in the water tank. The water in the water tank flows through the drainage holes and seeps continuously into the soil in the material box to simulate seepage under natural conditions.

[0035] It is understandable that artificial rainmaking machines are used to simulate natural rainfall with different intensities, amounts, and durations.

[0036] In some embodiments, guardrails are provided on both sides of the upper part of the hopper.

[0037] Understandably, guardrails form a physical barrier to prevent people from accidentally falling when they are near the edge.

[0038] This application utilizes multiple rows of through-holes to ensure thorough mixing of water and materials layer by layer, forming a debris flow within the material tank. This effectively reduces the workload of manual or mechanical material preparation and improves work efficiency. The multiple rows of through-holes on the water tank connected to the material tank enable seepage in large-scale mountain disaster dynamics experiments. Rainfall is achieved through an artificial rainfall mechanism located above the material tank. Under conditions of rainfall, seepage, and the coupling of rainfall and seepage, the entire process of a large-scale landslide transforming into a debris flow in large-scale mountain disaster dynamics experiments is realized. This allows for the simulation and research of prevention and control measures under the combined effects of multiple factors (rainfall, seepage, and the coupling of rainfall and seepage). Furthermore, this device provides important guidance for analyzing the initiation mechanism of large-scale landslides and determining the critical conditions for debris flow initiation, thus aiding in disaster forecasting and early warning. This application can simulate natural rainfall and seepage processes, including rainfall intensity, rainfall amount, and seepage flow, providing experimental conditions for research on the disaster formation mechanism and prevention and control measures of landslides and debris flows.

[0039] This application can record the slope changes under different rainfall conditions (light rain (10mm / 24h), moderate rain (25mm / 24h), heavy rain (50mm / 24h), torrential rain (70mm / 24h), extremely heavy rain (150mm / 24h), and exceptionally heavy rain (300mm / 24h)) and different seepage rates (water level in the pool reaching the first, second, third, and fourth rows of through holes). The recording continues until significant slope displacement occurs, and the occurrence of a landslide is confirmed through a detection system.

[0040] This application uses an artificial rainfall control system to adjust the rainfall and seepage flow through the rain nozzles and multiple rows of holes to change the rainfall and seepage conditions. Then, the rainfall and seepage continue until the slope is completely saturated and the gate is opened to form a debris flow phenomenon, thus transforming the landslide into a debris flow. The transformation time, rainfall, rainfall intensity, and rainfall duration are recorded by the artificial rainfall mechanism.

[0041] Please see Figure 1 and Figure 3 In some embodiments, the artificial rainmaking mechanism includes a water supply tank located on one side of the pool, multiple rainmaking supports located above the material tank, each rainmaking support being provided with multiple rainmaking nozzles, the water supply tank being connected to the nozzles via a first water supply pipe, a first booster pump being provided between the water supply tank and the first water supply pipe, and a first valve being provided on the first water supply pipe.

[0042] It is understandable that the water supply tank is connected to the sprinkler head via the first booster pump, the first valve, and the first water delivery pipe, in order to simulate natural rainfall under different rainfall intensities, amounts, and durations.

[0043] Please see Figure 2For example, there are 7 rain support brackets, and 3 rain nozzles are evenly spaced on each rain support bracket, for a total of 21 rain nozzles.

[0044] For example, water is pumped from a natural pool built at the bottom to a water tank located at the top of the platform via a high-pressure water pump and a DN100 water supply pipe. It takes 1.5 hours to quickly fill the water tank using the high-pressure water pump. The water tank is constructed of reinforced concrete, measuring 8 meters long, 3.5 meters wide, and 3 meters high, with a full water capacity of 70 cubic meters. This water tank can meet the water supply needs during large-scale experiments, ensuring that the normal operation of the experiments is not affected.

[0045] In some embodiments, the water tank is connected to the water supply tank via a second water supply pipe, a second booster pump is provided between the water supply tank and the second water supply pipe, and a second valve is provided on the second water supply pipe.

[0046] It is understandable that by controlling the opening of the second valve, the water level in the pool is controlled, and the water level in the pool is then used to control the amount of seepage and the level of seepage.

[0047] In some embodiments, the artificial rain and seepage device further includes a monitoring system and a control system. The monitoring system includes a sensor module located at the bottom of the material box and cameras located at the four corners of the upper part of the material box. The control system includes a controller, which is connected to the nozzle, the first pressurizing pump, the first valve, the second pressurizing pump, and the second valve, respectively.

[0048] Furthermore, the sensor module includes a pore water pressure sensor, model: JUL-PW28; a normal stress sensor, model: MK-003; and a ground vibration sensor, model: CCUBE.

[0049] A pore water pressure sensor is used to measure the pore water pressure in the soil inside the material box. Rainfall and / or seepage will increase the pore water pressure in the soil of the material box, thereby reducing the shear strength of the soil. Installing a pore water pressure sensor inside the material box can monitor the changes in pore water pressure under the influence of factors such as rainfall and seepage.

[0050] Normal stress sensors are an effective tool for monitoring the stability of soil and rock masses, enabling the monitoring of stress changes under the influence of factors such as self-weight, rainfall, and seepage. For example, during rainfall and / or seepage, rainwater seeps into the soil and rock mass of the material box, increasing pore water pressure and reducing effective normal stress. This change can be captured in real time by normal stress sensors and pore water pressure sensors. When the effective normal stress decreases to a certain extent, it may lead to slope instability.

[0051] Ground vibration sensors can monitor stress changes within a landslide body under external forces in real time. When the landslide body within the hopper is in a stable state, stress changes are relatively small and follow a certain pattern. However, when triggering factors cause the landslide body to become unstable, abnormal stress fluctuations occur, such as stress concentration and changes in stress direction. By analyzing these stress change data, the evolution of the mechanical state inside the hopper can be understood, providing important evidence for studying the landslide's gestation and development process and revealing its mechanism. Furthermore, by analyzing the monitored ground vibration sensor data, the vibration characteristics of the landslide body under different conditions can be analyzed. When the vibration characteristics of the landslide body show significant changes, such as a sudden increase in vibration frequency and amplitude, combined with changes in other monitoring indicators (pore water pressure, normal stress, etc.), the critical conditions for the landslide to transform into a debris flow can be determined.

[0052] The camera, model DS-2CD3T86FWDV3-I3S, is used to record the experimental process and monitor the changes in the slope inside the material box and the entire process of the landslide transforming into a debris flow, including slope deformation, the generation and development of cracks, how the landslide transforms into a debris flow, and velocity changes.

[0053] It is understandable that the monitoring and control system integrates various aspects and levels of the simulated rainfall experiment, such as experimental monitoring, rainfall control, data measurement and acquisition, into the control room of the top platform in order to achieve the goal of automation and intelligence in artificial rainfall.

[0054] Please see Figure 1 In some embodiments, a water collection tank is provided at the bottom of the hopper. It is understood that the sensor module is located within the water collection tank.

[0055] Please see Figure 5 and Figure 6 In some embodiments, the top of the gate is hinged to the hopper, and the bottom of the gate is provided with an automatic locking mechanism; the gate also includes a power device, which is connected to the gate via a steel wire rope.

[0056] It is understandable that the gate is subjected to a large lateral pressure from the clear water or water-soil mixture behind it, so it is necessary to ensure the water tightness before the gate is opened.

[0057] For example, the power equipment is used for opening and closing the gate. The power equipment is a high-power, high-speed winch-type gate opener with a main motor power of 250KW, a rated gate opening force of 2×125KN, and a rated rope speed of 63 meters / minute.

[0058] For example, the volume of the water-soil mixture contained in the bin is 500 cubic meters.

[0059] In this application, the material bin is filled with soil and water. The gate and automatic locking mechanism can meet the "water tightness" requirement under "high stress" environment. The automatic locking mechanism can automatically control rapid opening, meeting the "instantaneous opening" requirement of the gate turning angle exceeding 45° within 5 seconds. The heavy-duty gate of this application can withstand the lateral pressure caused by clear water or water-soil mixture. At the same time, the horizontal squeezing force generated when the automatic locking mechanism locks makes the gate water seal reach the designed compression amount, thereby meeting the sealing function under the lateral pressure generated by water or water-soil mixture. In addition, by shortening the time difference between the opening of the automatic locking mechanism and the starting of the power equipment, the motor of the power equipment can quickly intervene, thereby reducing the time that the gate's automatic locking mechanism is subjected to hydrostatic pressure or soil pressure after retraction, thereby achieving the purpose of instantaneous material release. It can completely realize the instantaneous release of materials.

[0060] Please see Figure 5 and Figure 6 In some embodiments, hinge seats are provided on both sides of the top of the gate, and steel wire ropes are provided on both sides of the bottom of the gate, with each steel wire rope connected to the power equipment.

[0061] It is understandable that the hinge support is embedded in both sides of the large concrete water tank through pre-embedded parts.

[0062] Alternatively, it can be understood that the power is provided by the wire rope pulled by the winch-type gate opener, allowing the gate to rotate and open around the top hinge seat.

[0063] In some embodiments, a support is provided above the gate, and two fixed pulleys are fixed on the support. Each wire rope passes around the corresponding fixed pulley and is connected to the power equipment.

[0064] Furthermore, a pressure sensor is provided at the fulcrum of each of the fixed pulleys.

[0065] Please refer to 5. Figure 6 , Figure 9 and Figure 10 In some embodiments, the automatic locking mechanism includes a locking groove located at the bottom of the gate, a pin that cooperates with the locking groove, a hydraulic pump connected to the upper part of the pin, and an oil pump also provided on one side of the upper part of the hopper, the hydraulic pump being connected to the oil pump.

[0066] Furthermore, the gate also includes an electrical control unit, which is electrically connected to the power equipment, pressure sensor, hydraulic pump, and oil pump.

[0067] Furthermore, the pin is wedge-shaped, and the locking groove matches the pin.

[0068] It is understood that electronic control units are conventional control devices in this field, and will not be elaborated upon here.

[0069] It is understandable that when the gate opens or closes, the pressure sensor monitors the pressure value at the fulcrum to determine the opening angle of the gate. During the gate opening process, the latch first retracts into place, the gate unlocks, and then the power equipment (winch-type gate hoist) quickly intervenes, winding the wire rope to pull up the gate. When the pressure sensor value exceeds the set maximum value, the motor of the winch-type gate hoist stops working, thus protecting the equipment. A high-precision photoelectric encoder is installed at the end of the drum of the winch-type gate hoist, which can dynamically control the gate opening angle. When the gate is opened to the maximum opening angle, the machine automatically stops. To further ensure the safety of the gate's rapid opening, a limit switch is installed at the hinge position. If the encoder fails, the limit switch will act as a limit stop protection.

[0070] It is understandable that during the loading process, the gate is tightly closed, and the two internal hydraulic cylinders drive the wedge-shaped pins to insert into the bottom locking groove. The wedge locking generates horizontal extrusion force so that the gate water seal reaches the designed compression amount, thereby satisfying the sealing function when water or water-soil mixture generates lateral pressure.

[0071] Please see Figure 7 and Figure 8 In some embodiments, the gate includes a main frame and a panel welded to the main frame; the main frame includes I-beams on both sides and a plurality of [unclear - possibly referring to components or elements] located between the I-beams. Π The main beam and the bottom beam located at the bottom of the I-beam side beam are provided with bottom beams. Π I-beam short beams are laid between the main beams.

[0072] For example, the height of the I-beam side beam is 1500mm, the panel is made of 14mm thick steel plate, and the bottom beam adopts a reinforced box structure to facilitate the installation of an automatic locking mechanism.

[0073] Understandably, the specially designed gate meets the strength and rigidity requirements, and its overall weight is controlled at around 40 tons. The weight is reduced as much as possible while meeting the stress requirements, making it a heavy-duty tilting gate.

[0074] In some embodiments, a water tank is provided on one side of the material box, and multiple rows of through holes are provided in the part of the material box adjacent to the water tank.

[0075] In some embodiments, the bottom of the hopper is inclined, and the gate is located on the lower side of the bottom of the hopper.

[0076] Working Process: When the gate is closed, it is difficult to close tightly due to lateral pressure. Therefore, two rectangular holes (0.3×0.3×0.5m) are pre-drilled at the bottom of the gate, serving as locking slots. A hydraulic pump support rod is installed above each hole, with a pin connected to the bottom of the rod. When the gate is closed (rotation angle 0), the rotation angle can be detected by reading the pressure sensor at the top to determine the gate's opening / closing angle. The higher the hydraulic pump pressure, the deeper the pin is inserted into the locking slot. The pressure value can be controlled by the electronic control unit to control the pin depth. The pin, in conjunction with the pre-fabricated locking slots, effectively solves the leakage problem under high stress. When the gate needs to be opened, the electrical control unit first reduces the pressure of the hydraulic pump, causing the pin to retract. When the pin retracts to the level of the bottom step of the gate (i.e., just after being pulled out of the pre-made square hole), the electrical control unit immediately starts the motor of the winch-type gate hoist. The steel cable connected to the motor is tightened, and the force direction is changed through the fixed pulley device, thereby lifting the gate. When the gate's opening angle reaches 45 degrees, the motor stops working and maintains the current torque value, stabilizing the gate at a 45-degree opening angle. When the gate needs to be closed, the motor restarts, slowly releasing the gate. When the gate's opening angle returns to 0 degrees, the motor repressurizes the hydraulic pump, causing the pin to re-insert into the pre-made square hole, completing the pressure fixation and preventing water leakage after the water tank is filled.

[0077] The embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
