[0058] In order to clearly describe the technical solutions of the present application, the following will briefly introduce some terms and technologies involved in the present application:

[0059] Sediment: In natural environment, sediment refers to the material accumulated at the bottom of water body due to physical, chemical or biological action. Sediment can include rock debris, soil particles, biological remains or wreckage, etc. In physical simulation experiment of sink, sediment is used to simulate the material composition of riverbed, lake bottom or seabed in nature, to study the erosion, transportation and deposition process under the action of water flow.

[0060] Landform model: refers to a simplified or reduced three-dimensional model made by artificial construction or computer simulation according to the topography and geomorphic features in nature. In physical simulation experiment of sink, landform model refers to the construction of different shapes, sizes and materials of sediment on the bottom of sink, to simulate the complex terrain of river, lake, coast, etc. in nature. Landform model is used to study the interaction between water flow and terrain, and the influence of terrain change on water flow characteristics.

[0061] Sediment-laden flow: In 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 physical simulation experiment of sink, sediment-laden flow is simulated by injecting water containing a certain concentration of sediment into the sink.

[0062] The technical solutions of the present application will be described in detail in the following specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The present application will be described in conjunction with the drawings.

[0063] In order to clearly understand the technical solutions of the present application, the solutions of the prior art will be described in detail.

[0064] Flume physics simulation experiments play a crucial role in the field of hydraulic engineering. By constructing flumes of different sizes and specifications, and combining them with sediment simulations to model different landforms, the flow of sediment-laden water within the flumes is controlled to observe the impact of water flow on sediments. This process is of great significance for studying a range of natural phenomena, including sediment transport, riverbed evolution, estuary and coastal changes, soil and water conservation, river ecology, river management, and water and sediment disasters.

[0065] The core of this experiment lies in scaling up the corresponding objects in nature to a proportional scale, designing and observing the interaction between water flow, sediment, and landform, thereby simulating the dynamic process of water flow in nature and studying the erosion, transportation, and deposition of sediments in a short period of time.

[0066] When research shifts to sedimentary geological processes with equivalent timeframes, the complexity of experiments increases significantly, requiring the inclusion of more control variables, such as sea-level rise and fall, periodic variations in sediment-laden currents, and the overall tilting or rising and falling of the flume.

[0067] Figure 1 This is a structural schematic diagram of an existing water tank device provided in an embodiment of this application. (See attached diagram.) Figure 1 As shown, a fixed water tank measuring 600cm long, 300cm wide, and 100cm high is displayed, with a slope 610 constructed within it. The water level in the fixed water tank is artificially controlled via a water inlet 620, a drainage 630, water pipes 640, and a self-priming pump 650, and sediment is supplied from upstream of the slope 610, thus realizing a physical simulation experiment of the water tank. However, the existing water tank equipment suffers from insufficient automation and information technology, resulting in inadequate control and observation accuracy of sedimentary geological processes.

[0068] Specifically, the main control variables in the flume physics simulation experiment include tectonic movement, upstream sediment supply, and water level fluctuations. Existing solutions primarily rely on manual or mechanical control, failing to achieve automated and precise control, resulting in insufficient control accuracy during the experiment.

[0069] Secondly, the existing water tank equipment is a three-dimensional device, which makes it difficult to observe the dynamic changes in the internal structure of the sediment during the experiment.

[0070] Finally, the existing water tank equipment lacks supporting data observation equipment, making it difficult to record and display the variables that need to be observed during the experiment.

[0071] Therefore, in view of the low automation and informatization level of the water tank equipment in the prior art, the control precision and observation precision of the sedimentary geological process are insufficient. In order to solve the problem, it is found in the research that firstly, the water flow and sediment in the water tank equipment can be quantitatively controlled by using automatic water level control and automatic sand-carrying water flow supply; secondly, the water tank automatic lifting control can be used to simulate the water body lifting process, thereby completing the simulation of the sedimentary basin filling process and the stratum superposition process; finally, advanced measurement technology can be used to track the water level change in the experiment. At the same time, the water tank equipment can be automatically and accurately controlled by a computer to complete the control of the water flow, the sediment supply amount, the water level height and the water tank inclination.

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

[0073] Figure 2 The structure of the two-dimensional automatic water tank equipment provided for the embodiments of the present application Figure 1 . As shown in Figure 2 , the two-dimensional automatic water tank equipment comprises:

[0074] a water tank system 100, a water level measurement system 200, a water supply and return control system 300, a sand-carrying water flow supply system 400 and an automatic slope changing system 500.

[0075] The water tank system 100 comprises a water tank frame 110, a water tank body 120 and a sliding rail 130 arranged on the water tank frame 110, and a water inlet and a drain arranged on the water tank body 120.

[0076] Specifically, the water tank frame 110 can be obtained by welding profiles, and is used to bear the overall structural weight of the water tank system 100. The water tank frame 110 comprises a main beam (not shown in the figure), a U-shaped structural frame and an edge frame, etc. Figure 2

[0077] The main beam is a structure connecting the U-shaped structural frame, and is selected by force calculation to meet the bearing capacity of the U-shaped structural frame and the lower fulcrum subcomponent, so that the overall deformation of the water tank system 100 is within an acceptable range. Further, in order to ensure the integrity and stiffness of the water tank system 100, a single fixed-length main beam is used, and the profiles used for the main beam are welded to form an integral beam.

[0078] The U-shaped structural frame and the edge frame jointly support the water tank body 120. The water tank body 120 is the part actually containing water, and is usually made of a material that is strong and wear-resistant. The shape of the water tank body 120 can be a cuboid, for example, with a size of 900 cm in length, 110 cm in width and 80 cm in height.

[0079] ​The edge frame of the top is provided with slide rails 130 to meet the erection requirement of the sand-entraining water flow supply system 400. Figure 3 The structural diagram of the slide rails provided by the embodiment of the present application is shown in FIG. 3. Figure 3 As shown in FIG. 3, the partial structure of the edge frame of the top and the slide rails mounted thereon is shown. The slide rails 130 can adopt a structure of stainless steel rack plus slide rails, and the bottom thereof is provided with an adjusting structure to improve the levelness of the slide rails 130, thereby improving the accuracy of the slide rails 130.

[0080] The water level measurement system 200 comprises at least one ultrasonic water level meter 210 mounted inside the sink main body 120.

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

[0082] The ultrasonic water level meter 210 is a device for measuring water level using ultrasonic technology, which can emit ultrasonic pulses and then receive signals reflected from the water surface, and determine the water level by calculating the time difference between the emission and reception signals.

[0083] The water supply and return control system 300 comprises a comprehensive control box, a water supply device, a water supply pipe 310 in communication with the water inlet, and a return pipe 320 in communication with the water outlet; the comprehensive control box is used to obtain the actual measurement information of the water level of the sink main body 120 from the at least one ultrasonic water level meter 210, and control the water level of the sink main body 120 through the water supply device according to the actual measurement information of the water level.

[0084] Specifically, the comprehensive control box is the control center of the two-dimensional automatic sink device, which is responsible for receiving the actual measurement information of the water level from the water level measurement system 200, and controlling the water supply device to supply water to the sink main body 120 according to the preset algorithm, so as to realize the automatic control of the water level of the sink main body 120.

[0085] Further, a water storage tank and a sand settling tank are arranged near the two-dimensional automatic sink device to realize the recycling of water flow and the sedimentation treatment of mud. The water supply pipe 310 is in communication with the water storage tank through the water supply device, and the water supply device is specifically used to provide clean water in the water storage tank to the sink main body 120; the return pipe 320 is in communication with the sand settling tank, and when the water and sand mixed liquid in the sink main body 120 needs to be discharged, they will flow into the sand settling tank through the return pipe 320, and natural sedimentation or artificial accelerated sedimentation is carried out in the sand settling tank, so that the mud is deposited at the bottom of the tank, and the clean water is gradually separated out.

[0086] Further, the sand trap and the water storage tank form a two-stage sedimentation system. After the water and sand are separated in the sand trap, the separated clean water is re-injected into the water storage tank for subsequent use.

[0087] The sand-laden water flow supply system 400 is slidingly connected to the slide rail 130, and is used to supply sand-laden water flow to the water tank body 120.

[0088] Specifically, the sand-laden water flow supply system 400 can slide along the edge frame on the slide rail 130, and is used to inject sand-laden water flow into the water tank body 120 at different positions to simulate the sand-laden flow in a river or a canal. As for the source of the sand-laden water flow, it can be prepared separately and injected into the sand-laden water flow supply system 400, or extracted from the sand trap, or extracted from the water storage tank and mixed with dry sand according to the demand.

[0089] The water tank 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 water tank body 120.

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

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

[0092] The structure of the automatic slope changing system 500 can also be an electric adjustment structure, and the automatic slope changing system 500 includes a motor, a speed reducer, a transmission device and other components. By rotating the motor to drive the lifting or tilting of the water tank system 100, the slope of the water tank body 120 can be changed.

[0093] The embodiment of the application provides a two-dimensional automatic flume device, which comprises a flume system, a water level measuring system, a water supply and return control system, a sand entraining flow supply system and an automatic slope changing system; the flume system comprises a flume frame, a flume main body and a sliding rail, and a water inlet and a drainage outlet formed in the flume main body; the water level measuring system comprises at least one ultrasonic water level meter; the water supply and return control system comprises a comprehensive control box, a water supply device, a water supply pipe and a water return pipe; the comprehensive control box is used for obtaining water level measured information from the at least one ultrasonic water level meter, and controlling the water level of the flume main body according to the water level measured information; the sand entraining flow supply system is used for supplying sand entraining flow to the flume main body; and the automatic slope changing system is used for controlling the slope of the flume main body. The following technical effects are achieved: the water level of the flume main body is automatically controlled by the water supply and return control system, and the lifting of the water level is simulated; the sand entraining flow is automatically supplied by the sand entraining flow supply system, and the supply of the upstream sediment is simulated; the slope of the flume main body is adjusted by the automatic slope changing system, and the simulation of the tectonic movement is realized; and the automation and informatization of the two-dimensional automatic flume device are improved by the water supply and return control system, the sand entraining flow supply system and the automatic slope changing system, and the problems of low control precision and observation precision of the sedimentary geological process are solved.

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

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

[0096] The water supply device comprises at least one first water supply pump and a corresponding frequency converter of each first water supply pump.

[0097] The comprehensive control box is specifically used for obtaining flow demand information according to the water level measured information, and controlling the rotating speed of the first water supply pump through the frequency converter according to the flow demand information.

[0098] Specifically, the water level height change of the flume main body 120 is controlled by the water supply and return flow. According to the water level height difference indicated by the water level measured information and the water level demand information, the flow demand information of the water level height change of the flume main body 120 can be calculated according to the specifications of the flume main body 120 and the bottom area of the flume main body 120. Then, the rotating speed of the first water supply pump is controlled through the frequency converter according to the flow demand information, so as to adjust the output flow. In order to adapt to the first water supply pumps with different flow specifications, the large flow and the small flow allowed in the experiment process should be able to maintain high control precision; meanwhile, the flow control blind area is controlled within a reasonable range, so as to meet the requirements of water and electricity saving in the experiment process. Optionally, the number of the first water supply pumps is two.

[0099] In the flow control process, the software program of the host computer in communication connection with the integrated control box sends a control instruction of an initial water level to the integrated control box. The integrated control box calculates water level demand information according to the initial water level and water level measurement information, and then obtains flow demand information. Subsequently, the integrated control box converts the flow demand information into a control signal and sends it to the frequency converter, so as to generate a certain flow in the water supply pipe 310. It should be noted that the host computer can be deployed locally, and the host computer and the integrated control box together form a local control system; or the host computer can be deployed in the cloud, and 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, which is used to adjust the flow of the water supply pipe 310 in cooperation with the first water supply pump; at the same time, the butterfly valve is also used to quickly cut off the water supply in an emergency to ensure the safety of the use of the sink body 120. In addition, the on-off valve is used to realize the full closure of the sink body 120 and the natural backflow of the water flow.

[0101] The technical effect of the embodiment of the present application is that the integrated control box outputs a control signal to control the speed of the first water supply pump through the frequency converter to generate a certain flow in the water supply pipe, thereby realizing the adjustment of the water level height of the sink body.

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

[0103] The electromagnetic flowmeter is installed upstream of the butterfly valve.

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

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

[0106] Figure 4 The principle diagram of the flow closed-loop control provided by the embodiment of the present application is shown in FIG. 6. Figure 4As shown, each hardware of the water supply and return control system 300 is synchronously controlled by the software on the integrated control box to achieve the purpose of accurately controlling the flow. The flow of the flow closed-loop control includes: the host computer sends a control instruction to the integrated control box, the integrated control box sends a control signal to the frequency converter according to the control instruction of the host computer and the water level measurement information of the electromagnetic flowmeter, and then the frequency converter controls the rotating speed of the first water supply pump to adjust the flow of the water supply pipe 310, and further adjust the water level height of the water tank body 120. During the water level height adjustment process, the electromagnetic flowmeter measures the flow in real time and sends the flow measurement information to the integrated control box in real time, and then the integrated control box sends the next control instruction to the frequency converter according to the flow difference value indicated by the flow measurement information and the flow demand information. In this way, through multiple closed-loop feedback adjustments, the flow in the water supply pipe 310 reaches the demand. During the above closed-loop feedback adjustment process, the circulating direction of the water flow is: water storage pool-first water supply pump-electromagnetic flowmeter-butterfly valve-water tank body 120-water storage pool.

[0107] Further, when the integrated control box communicates with the host 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 host computer, and convert the IT data of the host computer into OT data that can be recognized by each hardware.

[0108] In other embodiments, the integrated control box sends the water level measurement information to the host computer, and the host computer calculates the water level demand information according to the initial water level and the water level measurement information, and feeds back to the integrated control box. Further, the flow difference value can also be calculated by the host computer.

[0109] The technical effect of the embodiments of the 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 in communication connection with at least one ultrasonic water level meter 210, electromagnetic flowmeter, butterfly valve and on-off valve;

[0111] The integrated control box is also used to store and display the water level measurement information and the flow measurement 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 on-off valve.

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

[0114] As Figure 4As shown, the integrated 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 feed back the control results to the integrated control box, so as to feed back to the upper computer. Further, the integrated control box is also in communication connection with at least one frequency converter, so that the integrated control box obtains its own operation parameters from the frequency converter, so as to store and display the operation parameters and feed back to the upper computer.

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

[0116] The communication function is used to be responsible for the communication between the upper computer and each hardware of the water supply and return control system 300.

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

[0118] The device management function is used to integrate the management of the attributes of each hardware, such as device number, model and communication mode, etc.

[0119] The data management function is used to realize the storage, display, export and drawing of data, etc. For example, the data can be exported in pure text format or table format, etc.; for another example, the real-time change curve of water level and flow, the water level change curve along the way and the water level change process curve, etc. are displayed; wherein, the water level change process curve is drawn according to the historical water level of a single ultrasonic water level meter 210.

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

[0121] The technical effect of the embodiment of the present application is that through the integrated control box, the recording and display of the variables required to be observed in the experimental process are realized.

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

[0124] Specifically, the automatic slope changing system 500 comprises a center hinge 510 and two sets of elevators 520, the elevators 520 comprising lifting rods, driving motors and transmission devices, the driving motors being servo motors to realize high-precision control of the slope.

[0125] In a possible design, the comprehensive control box is simultaneously connected in communication with the two sets of elevators 520.

[0126] The comprehensive control box is further configured to store and display the slope of the sink body 120, wherein the slope of the sink body 120 is obtained by the comprehensive control box according to the lifting heights of the two sets of elevators 520 respectively.

[0127] Specifically, the slope changing control of the sink body 120 can be local control or remote control, both of which are realized by automatic control devices, and the real-time display of the slope changing process can be realized through digital setting operation. In addition, the elevators 520 further comprise limiting devices, which can ensure the accuracy and convenience of the lifting adjustment, and also ensure the overall safety of the sink body 120.

[0128] The host computer and / or the comprehensive control box can customize the slope as needed, but the maximum slope cannot exceed the limit value; in addition, the speed and time of slope changing and other parameters can be set, the speed of the sink body 120 in the vertical movement can be customized, and continuous slope changing and dynamic slope changing and the like are supported. During this period, the experimental process data, including the items of slope changing, the slope, the speed and the time, are automatically saved, and the work log is automatically generated and stored.

[0129] Further, the data of the elevators 520 and the hardware of the water supply and return control system 300 can be saved in any designated folder, and the folder is established in units of specified time, for example, the data of each day is saved under the folder, and the file is established according to the time when the system starts to run each time, and the data of each running is saved; if the continuous running time of the system exceeds 1 day, the file is saved in the folder where the system starts to run first.

[0130] Figure 6 A structure schematic diagram of the sand-carrying water flow supply system provided by the embodiment of the present application is shown in FIG. 1. Figure 6 As shown in FIG. 1, the structure of the sand-carrying water flow supply system is shown. In a possible design, the sand-carrying water flow supply system 400 comprises:

[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] The at least one peristaltic pump 420 is collectively configured to supply water to the water-sand mixing device 440, and the single-screw loss-in-weight feeder 430 is configured to supply sand to the water-sand mixing device 440.

[0133] Specifically, the supply support 410 is provided with a sliding block engaged with the rack of the sliding rail 130, which can be moved laterally along the sink body 120 by manual adjustment or automatic adjustment, and can be adjusted according to the experimental requirements to realize the adjustment of the sand-entraining water flow filling position.

[0134] The number of peristaltic pumps 420 can be two, which can meet the demand of large flow water supply by supplying water at the same time, or can meet the demand of standby water supply by supplying water alternatively.

[0135] The single-screw loss-in-weight feeder 430 includes a hopper, a feeder, a weighing system, and an adjuster. During sand feeding, the hopper, dry sand, and the feeder continuously weigh together. After the dry sand is sent out, the weighing system measures the real loss-in-weight rate and compares it with the set loss-in-weight rate to obtain the sand feeding quality of the dry sand. The single-screw loss-in-weight feeder 430 automatically corrects the deviation from the set point by adjusting the feeder rate, so as to uniformly and accurately continuously feed. It should be noted that the sand deposited in the sand settling tank is wet sand, and the sand supplied by the single-screw loss-in-weight feeder 430 is dry sand, so the sand in the sand settling tank cannot be directly used for the single-screw loss-in-weight feeder 430 and needs to be dried and periodically supplemented into the hopper of the single-screw loss-in-weight feeder 430. The drying of the wet sand can be realized by a drying box 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 sand-entraining water flow, which is filled into the sink body 120 together.

[0137] The technical effect of the present application is that the peristaltic pump supplies water at a constant flow rate, and the single-screw loss-in-weight feeder uniformly and accurately continuously feeds sand, so as to realize the accurate filling of the sand-entraining water flow.

[0138] In a possible design, the water-sand mixing device further includes a multi-stage sedimentation tank;

[0139] The backwater pipe 320 communicates with the first-stage sedimentation tank of the multi-stage sedimentation tank;

[0140] The at least one first water supply pump is collectively used for pumping the water stored in the last-stage sedimentation tank of the multi-stage sedimentation tank to the water supply pipe 310;

[0141] The sand-entraining water flow supply system 400 further includes at least one second water supply pump and a flat water tank 450;

[0142] The at least one second water supply pump is collectively used for pumping the water stored in the last-stage sedimentation tank of the multi-stage sedimentation tank to the flat water tank 450;

[0143] The at least one peristaltic pump 420 is 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 corresponds to the sand separation tank, and the last stage sedimentation tank corresponds to the water storage tank. In addition to the first stage sedimentation tank and the last stage sedimentation tank, the multi-stage sedimentation tank can also include several other stage sedimentation tanks to effectively remove the sediment in the water body.

[0145] The flat water tank 450 corresponds 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, so as to improve the stability of the peristaltic pump 420 in water supply. Further, the upper end of the flat water tank 450 is open and has a water level sensor. When the flat water tank 450 is full of water and is about to overflow, the second water supply pump stops water supply, and the water level in the flat water tank 450 no longer changes.

[0146] The technical effect of the present application is that the degree of water-sand separation is improved by the multi-stage sedimentation tank, and the stability of the peristaltic pump in constant flow water supply is further improved by the flat water tank.

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

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

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

[0150] At the same time, the water supply pipe 310 is filled with blind ditch material for energy dissipation, further reducing the water flow impact at the water inlet. The blind ditch, also known as a blind ditch, is mainly composed of coarse-grained materials such as gravel and gravel, and is paved with a filter layer, which has good water permeability.

[0151] The technical effect of the embodiment of the present application is that the water flow impact is reduced by the water supply pipe to ensure the stability of the water flow.

[0152] In a possible design, the water tank body 120 is made of transparent material without any obstruction.

[0153] Specifically, the transparent material can be super white toughened glass, transparent plastic or acrylic resin, etc., and the two long side walls of the water tank body 120 are made of such transparent material. As shown in the figure, each side is spliced by three pieces of glass, and in order 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 long and 110 cm wide, serving as an unobstructed experimental observation window; the size of the two side glasses is 250 cm long and 110 cm wide, used for observing the working conditions of the supporting equipment. Figure 2

[0154] Further, the bottom of the water tank body 120 is also made of glass. The glass is spliced on the inside of the main beam, the U-shaped structure frame and the edge frame, and a small gap is reserved at the splicing position. The gap is bonded by adhesive to realize the sealing of the water tank body 120, so as to reduce the influence of the glass joint on the experiment.

[0155] The technical effect of the embodiment is that the observation needs of the water tank body are realized through the transparent material without any obstruction.

[0156] The embodiment of the application also provides a control system, which comprises a host computer and a two-dimensional automatic water tank device as described above.

[0157] The two-dimensional automatic water tank device comprises a comprehensive control box, and the host computer is in communication connection with the comprehensive control box.

[0158] The control system provided by the embodiment of the application has similar implementation principles and technical effects to the two-dimensional automatic water tank device in the above embodiment, and details are not repeated here.
