By constructing flumes of different sizes and specifications, combined with sediment to simulate different geomorphic models, the sediment-laden flow is controlled to flow in the flume to observe the impact of flowing water on sediment. This process is of great significance for studying a series of natural phenomena such as sediment movement, riverbed evolution, estuary and coastal changes, soil and water conservation, river ecology, river regulation, and water and sediment disasters.

[0003] The core of this experiment lies in the proportional scaling of the corresponding objects in nature.

[0057] It should be noted that in this application, "when...", can refer to the instant when a certain situation occurs, or can refer to a period of time after a certain situation occurs. This application does not make specific limitations on this. In addition, a two-dimensional automated flume device and control system provided in this application are only examples, and the two-dimensional automated flume device and control system may also include more or less content. The user information (including but not limited to user device information and user personal information, etc.) and data (including but not limited to data for analysis, stored data, and displayed data, etc.) involved in one or more embodiments of this application are all information and data that have been authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data need to comply with relevant laws, regulations, and standards, and corresponding operation entrances are provided for users to choose to authorize or refuse.

[0058] For the convenience of clearly describing the technical solutions of this application, the following briefly introduces some terms and technologies involved in this application:

[0059] Sediment: In the natural environment, sediment refers to the substances that gradually accumulate at the bottom of a water body due to physical, chemical, or biological actions. Sediments can include rock debris, soil particles, biological remains or wreckage, etc. In a flume physical simulation experiment, sediment is used to simulate the material composition of riverbeds, lake bottoms, or sea bottoms in nature to study their erosion, transportation, and deposition processes under the action of water flow.

[0060] Geomorphic model: It refers to a simplified or reduced three-dimensional model made by artificial construction or computer simulation according to the topographic and geomorphic features in nature. In a flume physical simulation experiment, a geomorphic model refers to one constructed by arranging sediments of different shapes, sizes, and materials at the bottom of the flume to simulate complex terrains such as rivers, lakes, and coasts in nature. Geomorphic models are used to study the interaction between water flow and terrain, and the influence of terrain changes on water flow characteristics.

[0061] Sediment-laden flow: In the natural environment, sediment-laden flow refers to the water flow containing particles (mainly sediment). When the water flow passes through the riverbed or lake bottom, it will carry and transport these particles. In a flume physical simulation experiment, sediment-laden flow is simulated by injecting water containing a certain concentration of sediment into the flume.

[0062] The following uses specific embodiments to detail the technical solutions of this application. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe this application in conjunction with the accompanying drawings.

[0063] To clearly understand the technical solutions of this application, the solutions of the prior art will be introduced in detail first.

[0064] Physical simulation experiments of flumes play a crucial role in the field of hydraulic engineering. By constructing flumes of different sizes and specifications, combined with sediment to simulate different geomorphic models, the sediment-laden flow is controlled to flow in the flume to observe the impact of flowing water on sediment. This process is of great significance for studying a series of natural phenomena such as sediment movement, riverbed evolution, estuary and coastal changes, soil and water conservation, river ecology, river regulation, and water and sediment disasters.

[0065] The core of this experiment lies in the proportional scaling of the corresponding objects in nature. Experimental designs and observations are carried out around the interactions among flowing water, sediment, and geomorphology, so as to simulate the dynamic process of flowing water in nature and study the erosion, transportation, and deposition processes of sediment in a short period.

[0066] When the research turns to sedimentary geological processes with a much longer equivalent time, the complexity of the experiment increases significantly, and more control variables must be incorporated, such as the rise and fall of sea level, the periodic changes of sediment-laden flow, and the tilting or lifting of the entire flume.

[0067] Figure 1 The structural schematic diagram of the existing flume equipment provided for the embodiments of this application. As Figure 1 shown, it shows a fixed flume with a length of 600 cm, a width of 300 cm, and a height of 100 cm. A slope 610 is built in the fixed flume. By means of a water filling pool 620, a drainage pool 630, a water pipe 640, and a self-priming pump 650, the water level of the fixed flume is artificially controlled, and sediment is supplied from the upstream of the slope 610, realizing the physical simulation experiment of the flume. However, the existing flume equipment has insufficient automation and informatization levels, resulting in insufficient control accuracy and observation accuracy of sedimentary geological processes.

[0068] Specifically, first, the main control variables of the physical simulation experiment of the flume include: tectonic movement, the supply of upstream sediment, and the rise and fall of the water level. The existing solutions mainly rely on manual or mechanical control and have not achieved automated precise control, resulting in insufficient control accuracy during the experiment.

[0069] Secondly, the existing flume equipment is a three-dimensional equipment, making it difficult to observe the dynamic change process of the internal structure of sediment during the experiment.

[0070] Finally, the existing flume equipment lacks supporting data observation equipment, resulting in difficulty in recording and displaying the variables to be observed during the experiment.

[0071] Therefore, aiming at the problem that the automation and informatization levels of the flume equipment in the prior art are insufficient, resulting in insufficient control accuracy and observation accuracy in the sedimentary geological process. In order to solve this problem, it is found in the research that, firstly, the water flow and sediment in the flume equipment can be quantitatively controlled by using automatic water level control and automatic supply of sediment-laden water flow; secondly, the automatic lifting control of the flume can be used to simulate the process of water body rising and falling, and then the simulation of the sedimentary basin filling process and the stratigraphic stacking process can be completed; finally, advanced measurement techniques can be used to track the water level changes during the experiment. At the same time, the flume equipment can be automatically and precisely controlled by a computer to complete the control of water flow rate, sediment supply amount, water level height and flume inclination.

[0072] Based on the above creative findings, the technical solution of this application is proposed.

[0073] Figure 2 Structural schematic of the two-dimensional automatic flume equipment provided in the embodiment of this application Figure 1 . As Figure 2 shown, the two-dimensional automatic flume equipment includes:

[0074] A flume system 100, a water level measurement system 200, a water supply and return control system 300, a sediment-laden water flow supply system 400, and an automatic slope-changing system 500;

[0075] The flume system 100 includes: a flume frame 110, a flume main body 120 and a slide rail 130 provided on the flume frame 110, and a water inlet and a drain outlet opened on the flume main body 120.

[0076] Specifically, the flume frame 110 can be obtained by welding profiles and is used to bear the overall structural weight of the flume system 100. The flume frame 110 includes main beams ( Figure 2 the main beams are not shown in the figure), U-shaped structural frames and edge frames, etc.

[0077] The main beam is a structure connecting the U-shaped structural frames, and the material selection is subject to force calculation to meet the bearing capacity of the U-shaped structural frames and the lower support sub-components, so that the overall deformation of the flume system 100 is within an acceptable range; further, in order to ensure the integrity and stiffness of the flume system 100, a single fixed-length main beam is used, and the profiles used for the main beam are welded together into an integral beam.

[0078] The U-shaped structural frame and the edge frame jointly support the flume main body 120. The flume main body 120 is the actual part for holding water and is usually made of strong and wear-resistant materials. The shape of the flume main body 120 can be a cuboid. For example, its dimensions are 900 cm in length, 110 cm in width and 80 cm in height.

[0079] A slide rail 130 is installed on the edge frame at the top to meet the erection requirements of the sediment-laden water supply system 400. Figure 3 This is a schematic structural diagram of the slide rail provided by the embodiment of the present application. As Figure 3 shown, a partial structure of the edge frame at the top and the slide rail installed thereon is shown. The slide rail 130 can adopt a structure of a stainless steel rack plus a slide rail, and an adjustment structure is provided at its bottom to improve the levelness of the slide rail 130, thereby improving the accuracy of the slide rail 130.

[0080] The water level measurement system 200 includes at least one ultrasonic water level gauge 210 installed inside the water tank main body 120.

[0081] Specifically, the water level measurement system 200 is composed of a hardware part and a software part. The hardware part includes at least one ultrasonic water level gauge 210 for collecting and transmitting water level information; the software part realizes the acquisition control of water level information by sending acquisition control instructions to the hardware part, and at the same time, the software part can provide functions such as viewing, storing, outputting water level information, and displaying the change of water level along the way.

[0082] Among them, the ultrasonic water level gauge 210 is a device that uses ultrasonic technology to measure the water level. It can emit ultrasonic pulses, then receive the signal reflected from the water surface, and determine the water level by calculating the time difference between the transmitted and received signals.

[0083] The water supply and return control system 300 includes: an integrated control box, a water supply device, a water supply pipe 310 communicating with the water inlet, and a return water pipe 320 communicating with the drain outlet; the integrated control box is used to obtain the actual measured water level information of the water tank main body 120 from at least one ultrasonic water level gauge 210, and control the water level of the water tank main body 120 through the water supply device according to the actual measured water level information.

[0084] Specifically, the integrated control box is the control center of the two-dimensional automatic water tank device, responsible for receiving the actual measured water level information from the water level measurement system 200, and combining a preset algorithm to control the water supply device to supply water to the water tank main body 120 to realize the automatic control of the water level of the water tank main body 120.

[0085] Furthermore, a reservoir and a sedimentation tank are arranged near the two-dimensional automatic water tank device to realize the recycling of water flow and the sedimentation treatment of sediment. Among them, the water supply pipe 310 is connected to the reservoir through the water supply device, and the water supply device is specifically used to supply the clear water in the reservoir to the water tank main body 120; the return water pipe 320 is connected to the sedimentation tank. When the water-sand mixture in the water tank main body 120 needs to be discharged, they will flow into the sedimentation tank through the return water pipe 320, and natural sedimentation or artificial accelerated sedimentation will be carried out in the sedimentation tank, so that the sediment is deposited at the bottom of the tank, and the clear water is gradually separated.

[0086] Furthermore, the sand sedimentation tank and the reservoir form a two-stage sedimentation system. After the separation of water and sand is completed in the sand sedimentation tank, the separated clear water will flow back into the reservoir for subsequent use.

[0087] The sediment-laden water supply system 400 is slidably connected to the slide rail 130, and the sediment-laden water supply system 400 is used to supply sediment-laden water to the flume main body 120.

[0088] Specifically, the sediment-laden water supply system 400 can slide on the slide rail 130 along the edge frame, and is used to inject sediment-laden water into the flume main body 120 at different positions to simulate the sediment-laden flow in a river or a canal. Regarding the source of the sediment-laden water, it can be prepared separately and injected into the sediment-laden water supply system 400, or extracted from the above-mentioned sand sedimentation tank, or the clear water can be first extracted from the above-mentioned reservoir and then dry sediment is separately added according to requirements for mixing.

[0089] The flume frame 110 is arranged on the automatic slope-changing system 500, and the automatic slope-changing system 500 is used to control the slope of the flume main body 120.

[0090] Specifically, by adjusting the slope of the flume main body 120 through the automatic slope-changing system 500, the flow of water and sediment under different terrain conditions can be simulated, such as the steep slope of a mountain river and the gentle slope of a plain river.

[0091] The structure of the automatic slope-changing system 500 can be a mechanical adjustment structure. Then the automatic slope-changing system 500 includes a plurality of liftable supports, or a liftable platform, and the flume frame 110 is fixed on the support or the platform. By adjusting the height of the support or the platform, the slope of the flume main body 120 can be changed.

[0092] The structure of the automatic slope-changing system 500 can also be an electric adjustment structure. Then the automatic slope-changing system 500 includes components such as a motor, a reducer and a transmission device. By rotating the motor to drive the lifting or tilting of the flume system 100, the slope of the flume main body 120 can be changed.

[0093] A two-dimensional automated flume device provided by an embodiment of the present application, the device includes: a flume system, a water level measurement system, a water supply and return control system, a sediment-laden flow supply system, and an automatic slope-changing system; the flume system includes a flume frame, a flume body, and slide rails, as well as a water inlet and a drain outlet opened on the flume body; the water level measurement system includes at least one ultrasonic water level gauge; the water supply and return control system includes an integrated control box, a water supply device, a water supply pipe, and a return water pipe; the integrated control box is used to obtain the measured water level information from at least one ultrasonic water level gauge and control the water level of the flume body based on this; the sediment-laden flow supply system is used to supply sediment-laden flow to the flume body; the automatic slope-changing system is used to control the slope of the flume body. The following technical effects are achieved: the automatic control of the water level of the flume body is realized through the water supply and return control system, and the simulation of the rise and fall of the water level is realized; the automatic supply of sediment-laden flow is realized through the sediment-laden flow supply system, and the simulation of the supply of upstream sediments is realized; the slope of the flume body is adjusted through the automatic slope-changing system, and the simulation of tectonic movement is realized; through the water supply and return control system, the sediment-laden flow supply system, and the automatic slope-changing system, the automation and informatization of the two-dimensional automated flume device are improved, and the problems of insufficient control accuracy and observation accuracy in the sedimentary geological process are solved.

[0094] In a possible design, the water supply and return control system 300 further includes:

[0095] A butterfly valve installed on the water supply pipe 310 and a switch valve installed on the return water pipe 320;

[0096] The water supply device includes: at least one first water supply pump and a frequency converter corresponding to each first water supply pump;

[0097] The integrated control box is specifically configured to obtain the flow demand information according to the measured water level information, and control the rotation speed of the first water supply pump through the frequency converter according to the flow demand information.

[0098] Specifically, the change in the water level height of the flume body 120 is controlled by the water supply and return flow. The integrated control box can calculate the flow demand information for the change in the water level height of the flume body 120 based on the specifications of the flume body 120, the bottom area of the flume body 120, and the difference in the water level height indicated by the measured water level information and the water level demand information. Then, according to the flow demand information, the rotation speed of the first water supply pump is controlled through the frequency converter to adjust the output flow. To adapt to first water supply pumps with different flow specifications, both the maximum flow and the minimum flow allowed during the experiment should be able to maintain high control accuracy; at the same time, the flow control blind area is controlled within a reasonable range to meet the requirements of water and electricity conservation during the experiment. Optionally, the number of first water supply pumps is two.

[0099] During the flow control process, the software program of the host computer communicatively connected to the integrated control box sends a control instruction for the initial water level to the integrated control box. The integrated control box calculates the water level demand information based on the initial water level and the measured water level information, and then obtains the flow demand information. Subsequently, the integrated control box converts it into a control signal and sends it to the frequency converter, so as to generate a certain flow rate in the water supply pipe 310. It should be noted that the host computer can be deployed locally, in which case the host computer and the integrated control box together form a local control system; the host computer can also be deployed in the cloud, in which case the host computer and the integrated control box together form a cloud control system.

[0100] Further, the butterfly valve changes the flow area of the water supply pipe 310 by rotating the butterfly plate inside it, and is used to cooperate with the first water supply pump to adjust the flow rate of the water supply pipe 310; at the same time, the butterfly valve is also used to quickly cut off the water supply in case of emergency to ensure the safe use of the water tank main body 120. In addition, the on-off valve is used to achieve the full closure of the water tank main body 120 and the natural backflow of water.

[0101] The technical effect of the embodiment of the present application is that the integrated control box outputs a control signal, controls the rotation speed of the first water supply pump through the frequency converter, generates a certain flow rate in the water supply pipe, and realizes the adjustment of the water level height of the water tank main body.

[0102] In a possible design, the water supply and return control system 300 further includes:

[0103] An electromagnetic flowmeter installed on the water supply pipe 310; wherein, the electromagnetic flowmeter is installed upstream of the butterfly valve;

[0104] The integrated control box is further configured to obtain the measured flow information of the water supply pipe 310 from the electromagnetic flowmeter, and feedback and control the flow demand information according to the measured flow information.

[0105] Specifically, the electromagnetic flowmeter is used to measure the flow rate of the water supply pipe 310 in real time. Then, the integrated control box feedback-controls the flow demand information through the measured flow information of the water supply pipe 310, that is, closed-loop control. Among them, the electromagnetic flowmeter is installed upstream of the butterfly valve. The effect of this setting is to reduce the influence of the water flow of the butterfly valve to improve the measurement accuracy of the electromagnetic flowmeter.

[0106] Figure 4 It is a schematic diagram of the principle of the flow closed-loop control provided by the embodiment of the present application. As Figure 4As shown in the figure, each hardware of the supply and return water control system 300 is synchronously controlled by the software installed on the integrated control box to achieve the purpose of accurately controlling the flow rate. The process of flow closed-loop control includes: the upper computer sends a control instruction to the integrated control box, and the integrated control box sends a control signal to the frequency converter according to the control instruction of the upper computer and the measured water level information of the electromagnetic flowmeter. Then the frequency converter controls the rotation speed of the first water supply pump to adjust the flow rate of the water supply pipe 310, and further adjusts the water level height of the water tank body 120. During the adjustment of the water level height, the electromagnetic flowmeter measures the flow rate in real time and sends the measured flow rate information to the integrated control box in real time. Then the integrated control box sends the next control instruction to the frequency converter according to the flow difference jointly indicated by the measured flow rate information and the flow rate demand information. This process is repeated, and the flow rate in the water supply pipe 310 reaches the demand through multiple closed-loop feedback regulations. In the above closed-loop feedback regulation process, the circulation direction of the water flow is in turn: water storage tank - first water supply pump - electromagnetic flowmeter - butterfly valve - water tank body 120 - water storage tank.

[0107] Further, when the integrated control box communicates with the upper computer, it is also used to convert the Operational Technology (OT) data of each hardware into Information Technology (IT) data that can be recognized by the upper computer, and convert the IT data of the upper computer into OT data that can be recognized by each hardware.

[0108] In other embodiments, the integrated control box sends the measured water level information to the upper computer, and the upper computer calculates the water level demand information based on the initial water level and the measured water level information and feeds it back to the integrated control box. Further, the flow difference can also be calculated by the upper computer.

[0109] The technical effect of the embodiment of the present application is that the control accuracy of the water level height of the water tank body is improved through feedback control.

[0110] In a possible design, the integrated control box is communicatively connected to at least one ultrasonic water level gauge 210, an electromagnetic flowmeter, a butterfly valve, and a switching valve at the same time;

[0111] The integrated control box is also used to store and display the measured water level information and the measured flow rate information;

[0112] The integrated control box is also used to control the opening degree of the butterfly valve and the opening and closing of the switching valve.

[0113] Specifically, the measured water level information and the measured flow rate information can be stored on the memory of the integrated control box and displayed locally; further, both can also be stored on the memory of the upper computer and displayed remotely.

[0114] As Figure 4As shown, the comprehensive control box is also used to control the opening degree of the butterfly valve and the opening and closing of the on-off valve. After the control is completed, the butterfly valve and the on-off valve feedback the control results to the comprehensive control box, so that the comprehensive control box can feedback to the upper computer. Further, the comprehensive control box is also communicatively connected to at least one frequency converter, and the comprehensive control box obtains its own operating parameters from the frequency converter, so as to store and display the operating parameters and feedback them to the upper computer.

[0115] Further, according to the experimental requirements, the software installed on the comprehensive control box supports the following functions:

[0116] Communication function, which is responsible for the communication between the upper computer and each hardware of the water supply and return control system 300.

[0117] Control function, which is used to realize the intelligent control of each hardware. For example, the fine adjustment of the flow rate is realized through manual control, the constant flow control of the flow rate is realized through feedback control, and the non-constant flow control of the flow rate is realized through file control, etc.

[0118] Device management function, which is used to integrate and manage the attributes of each hardware such as device number, model, and communication method.

[0119] Data management function, which is used to realize the storage, display, export, and charting of data, etc. For example, the data can be exported in plain text format or table format, etc.; for another example, the real-time change curves of water level and flow rate, the along-channel change curve of water level, and the change process curve of water level are displayed, etc.; among them, the change process curve of water level is drawn based on the historical water level of a single ultrasonic water level gauge 210.

[0120] Further, the software installed on the upper computer, in addition to the above data management function, also supports the data acquisition function, that is, according to the experimental requirements, the acquisition frequency of the measured water level information is customized. It should be noted that the acquisition frequency cannot exceed the maximum frequency of the ultrasonic water level gauge 210.

[0121] The technical effect of the embodiment of the present application is that through the comprehensive control box, the recording and display of the variables to be observed during the experiment are realized.

[0122] Figure 5 This is the structural schematic of the two-dimensional automated flume device provided by the embodiment of the present application Figure 2 . As Figure 5 shown, in a possible design, the automatic slope-changing system 500 includes: a central hinge 510 and two sets of elevators 520;

[0123] The central hinge 510 is hinged at the central position of the flume frame 110, and the two sets of elevators 520 are respectively supported at both ends of the flume frame 110.

[0124] Specifically, the automatic slope-changing system 500 includes: a central hinge 510 and two sets of elevators 520. The elevator 520 includes a lifting rod, a driving motor, and a transmission device. The driving motor adopts a servo motor to achieve high-precision control of the slope.

[0125] In a possible design, the integrated control box is communicatively connected to the two sets of elevators 520 at the same time;

[0126] The integrated control box is also used to store and display the slope of the water tank main body 120; wherein, the slope of the water tank main body 120 is obtained by the integrated control box according to the respective lifting heights of the two sets of elevators 520.

[0127] Specifically, the slope-changing control of the water tank main body 120 can be local control or remote control. Both use automatic control equipment, and through digital setting operations, the real-time display of the slope-changing process can be realized. In addition, the elevator 520 also includes a limit device, which can not only ensure the accuracy and convenience of lifting adjustment, but also ensure the overall safety of the water tank main body 120.

[0128] The host computer and / or the integrated control box can customize the slope as needed, but the maximum slope cannot exceed the limit value; in addition, parameters such as the slope-changing speed and time can also be set to customize the vertical movement speed of the water tank main body 120, and continuous slope-changing and dynamic slope-changing are supported. During this period, the experimental process data will be automatically saved, including slope-changing entries, slope, speed, and time, etc., and a work log will be automatically generated and stored.

[0129] Furthermore, the data of each hardware of the elevator 520 and the water supply and return control system 300 can be saved in any specified folder. Folders are established in units of specified time. For example, the data of each day is saved in this folder, and files are established according to the time when the system starts running each time to save the data of each run; if the system runs continuously for more than 1 day, the files are saved in the folder where it was originally located.

[0130] Figure 6 It is a schematic structural diagram of the sediment-laden water supply system provided by the embodiment of the present application. As Figure 6 shown, the structure of the sediment-laden water supply system is shown. In a possible design, the sediment-laden water supply system 400 includes:

[0131] a supply bracket 410 slidably connected to the slide rail 130, and at least one peristaltic pump 420, a single-screw loss-in-weight feeder 430, and a water-sand mixing device 440 installed on the supply bracket 410;

[0132] At least one peristaltic pump 420 is jointly used to supply water to the water-sand mixing device 440, and the single-screw loss-in-weight feeder 430 is used to supply sand to the water-sand mixing device 440.

[0133] Specifically, a slider meshing with the rack of the slide rail 130 is provided on the supply bracket 410, which can move horizontally along the water tank main body 120 in a manually adjustable or automatically adjustable manner, and the injection position of the sediment-laden water flow can be adjusted according to experimental requirements.

[0134] The number of peristaltic pumps 420 can be two. If they supply water simultaneously, the demand for large-flow water supply can be met; if they supply water alternatively, the demand for standby water supply can be met.

[0135] The single-screw loss-in-weight feeder 430 includes a hopper, a feeder, a weighing system, and a regulator. During the sand addition process, the hopper, the dry sediment, and the feeder are continuously weighed together. After the dry sediment is sent out, the weighing system measures the actual weight loss rate and compares it with the set weight loss rate in the experiment to obtain the sand addition quality of the dry sediment. The single-screw loss-in-weight feeder 430 automatically corrects the deviation value from the set point by adjusting the feeder speed, so as to continuously feed materials evenly and accurately. It should be noted that the sediment deposited in the sedimentation tank is wet sand, while the sand supplied by the single-screw loss-in-weight feeder 430 is dry sand. Therefore, the sediment in the sedimentation tank cannot be directly used for the single-screw loss-in-weight feeder 430, and dry sand needs to be regularly replenished into the hopper of the single-screw loss-in-weight feeder 430 after drying; the drying of wet sand can be achieved through a drying oven or by natural air drying.

[0136] The water-sand mixing device 440 includes a mixing funnel. The water supplied by the peristaltic pump 420 and the sand supplied by the single-screw loss-in-weight feeder 430 are mixed in the mixing funnel to form a sediment-laden water flow, which is then injected into the water tank main body 120 together.

[0137] The technical effect of this application is that precise injection of the sediment-laden water flow is achieved by supplying water at a constant flow rate by the peristaltic pump and continuously supplying sand evenly and accurately by the single-screw loss-in-weight feeder.

[0138] In a possible design, it further includes: a multi-stage sedimentation tank;

[0139] The return water pipe 320 is connected to the first-stage sedimentation tank of the multi-stage sedimentation tank;

[0140] At least one first water supply pump is jointly used to pump the water stored in the last-stage sedimentation tank of the multi-stage sedimentation tank to the water supply pipe 310;

[0141] The sediment-laden water flow supply system 400 further includes: at least one second water supply pump and a water level tank 450;

[0142] At least one second water supply pump is jointly used to pump the water stored in the last-stage sedimentation tank of the multi-stage sedimentation tank to the water level tank 450;

[0143] At least one peristaltic pump 420 is commonly used to pump the water stored in the flat water tank 450 to the water-sand mixing device 440.

[0144] Specifically, the first-stage sedimentation tank is equivalent to the above-mentioned sand sedimentation tank, and the last-stage sedimentation tank is equivalent to the above-mentioned reservoir. In addition to the first-stage sedimentation tank and the last-stage sedimentation tank, the multi-stage sedimentation tank may further include several other stages of sedimentation tanks to effectively remove sediment in the water body.

[0145] The flat water tank 450 is equivalent to a relay station. The second water supply pump first pumps the water in the last-stage sedimentation tank to the flat water tank 450, and then the peristaltic pump 420 pumps the water in the flat water tank 450 to the water-sand mixing device 440 to improve the stability of the water supply of the peristaltic pump 420. Further, the upper end of the flat water tank 450 is open and is internally provided with a water level sensor. When the flat water tank 450 is full of water and about to overflow, the second water supply pump stops supplying water, and then the water level of the flat water tank 450 no longer changes.

[0146] The technical effect of this application is that the degree of water-sand separation is improved through the multi-stage sedimentation tank; the stability of the constant-flow water supply of the peristaltic pump is further improved through the flat water tank.

[0147] Figure 7 It is a schematic structural diagram of the water supply pipe provided by the embodiment of this application. Figure 8 It is a schematic structural diagram of the water return pipe provided by the embodiment of this application. As Figure 7 and Figure 8 shown, in a possible design, both the water supply pipe 310 and the water return pipe 320 are arranged below the water tank main body 120.

[0148] The shape of the water supply pipe 310 is in a diffused shape, and a blind ditch is arranged in the water supply pipe 310.

[0149] Specifically, the shape of the water supply pipe 310 being in a diffused shape means that the cross-sectional area of one end of the water supply pipe 310 close to the water inlet is larger than the cross-sectional area of the end far from the water inlet, forming a shape similar to a funnel. This design helps the water flow to be more evenly distributed in the water supply pipe 310, reduces the water flow impact at the water inlet, achieves the effect of energy dissipation and turbulence, and ensures the stability of the water flow.

[0150] At the same time, the water supply pipe 310 is filled with blind ditch materials for energy dissipation to further reduce the water flow impact at the water inlet. Among them, the blind ditch, also known as the subsurface drain, is mainly composed of coarse-grained materials such as filled broken stones and gravels, and is paved with an inverted filter layer, having good water permeability.

[0151] The technical effect of the embodiment of this application is that the water flow impact is reduced through the water supply pipe, and the stability of the water flow is ensured.

[0152] In a possible design, the structural material of the water tank body 120 is an unobstructed transparent material.

[0153] Specifically, the transparent material can be ultra-white tempered glass, transparent plastic, acrylic resin, etc. Both long side walls of the water tank body 120 are made of this transparent material. As Figure 2 shown, each side is composed of three pieces of glass spliced together. To meet the observation needs, the size of the middle glass should be as large as possible. For example, the size of the middle glass is 400 cm in length and 110 cm in width, serving as an unobstructed experimental observation window; the size of the two side glasses is 250 cm in length and 110 cm in width, used to observe the working conditions of the supporting equipment.

[0154] Furthermore, the bottom of the water tank body 120 is also made of glass. The glass is spliced inside the main beam, U-shaped structural frame, and edge frame, and a small indirect seam is reserved at the splicing point. The seam is bonded through an adhesive to achieve the sealing of the water tank body 120, so as to reduce the influence of the glass joints on the experiment.

[0155] The technical effect of this embodiment is that the observation needs of the water tank body are realized through the unobstructed transparent material.

[0156] This application embodiment also provides a control system, including: a host computer, and a two-dimensional automated water tank device as described in the above embodiment;

[0157] The two-dimensional automated water tank device includes an integrated control box, and the host computer is communicatively connected to the integrated control box.

[0158] The control system provided by this application embodiment has the same implementation principle and technical effect as the two-dimensional automated water tank device in the above embodiment, and will not be elaborated here in this embodiment.
