Description

Technical Field

[0001] The present application belongs to the technical field of clay soil anti-scouring, and in particular to an intelligent clay soil anti-scouring testing device. Background Art

[0002] Clay has strong anti-scour ability, and its anti-scour ability determines the erosion rate of the river bank. In order to estimate the erosion rate of the river bank, it is very important to determine the starting conditions, erosion coefficient and the quantitative relationship between the clay soil. For this purpose, it is necessary to conduct clay soil starting conditions and scour tests. In traditional clay soil anti-scour test devices, soil samples are generally pushed manually to move, and the water flow scours the top of the soil sample to measure relevant data. However, the manual push of soil sample movement increases the difficulty and convenience of operation. At the same time, the speed of manual push of soil samples is sometimes fast and sometimes slow, which also affects the accuracy of the test data. Based on this, an intelligent clay soil anti-scour test device is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1-8 The present application provides a technical solution: an intelligent clay soil anti-scour testing device, comprising two support assemblies, namely a first support assembly 1 and a second support assembly 2, and the two are placed in parallel, the former is higher than the latter, an actuator 4 is installed in the middle of the first support assembly 1, which is used to push the soil sample into the interior of the experimental tube 9, and a symmetrically distributed third support frame 3 is installed on the top surface of the first support assembly 1, and a fastening assembly is arranged on the top of both of them, and an experimental tube 9 is horizontally placed above the first support assembly 1, and conversion tubes 10 connected to the experimental tube 9 are installed at both ends of the outside of the experimental tube 9, and the conversion tube 10 is fixedly connected to the fastening assembly, and a baffle 17 is installed in the middle of the inner wall of the left conversion tube 10, which is used to adjust the water flow so that the water flow enters the experimental tube at a uniform speed. 9, a sample tube 5 and a rangefinder 6 are respectively installed above and below one end of the experimental tube 9 near the outside of the baffle 17, the two are in line and arranged vertically, a piston 18 is installed inside the sample tube 5, and its surface is in contact with the output end of the actuator 4, a first water tank 13 and a second water tank 12 are placed above the second support frame 2, both are placed horizontally, the first water tank 13 stores water, and the second water tank 12 is used to receive the return water of the impact clay soil, a liquid pump 14 for pumping water is installed on the side of the first water tank 13, which is connected to the conversion tube 10 installed with the baffle 17 through a pipeline, the second water tank 12 is opened at the top, and a water inlet pipe 15 is installed on one side, and the water inlet end of the water inlet pipe 15 is connected to another conversion tube 10 through a pipeline.

[0033] By adopting this solution, two conversion tubes 10 are installed at both ends of the experimental tube 9. The two conversion tubes 10 are respectively connected to the water pump 14 and the water inlet pipe 15 through pipelines to form a water flow impact channel. The experimental tube 9 can be made of transparent material, which is convenient for users to visually observe the entire flushing process of clay soil. At the same time, the rangefinder 6 continuously measures the size of its bottom and the top of the clay soil sample. When the clay soil sample entering the experimental tube 9 is flushed, the rangefinder 6 measures that the size of the top of the clay soil sample increases, and then controls the actuator 4 to extend, pushing the piston 18 and the clay soil sample to move upward, thereby ensuring the accuracy of the subsequent detection results.

[0034] In the present application embodiment:

[0035] Reference Figure 1 and Figure 7 The four corners of the bottom surface of the second support component 2 are provided with adjustable support legs. The second support component 2 is in the shape of a rectangular box with an opening on the top, and the bottom wall is provided with a plurality of through holes in a uniform array, which provide a placement position for the first water tank 13 and the second water tank 12 and limit the two. At the same time, the hollow structure of the second support component 2 can reduce its relative weight, making it easy for users to disassemble, carry and transport.

[0036] In the present application embodiment:

[0037] Reference Figure 1 and Figure 3 The fastening components are composed of two half rings 16 and two fasteners. The two half rings 16 are opposite to each other and connected by fasteners. The semi-ring structure of this structure makes it easy to connect the two half rings 16 to each other and put them in the middle position of the conversion tube 10, so as to facilitate the stable support of the two conversion tubes 10. The two conversion tubes 10 are flange-connected to the two ends of the experimental tube 9, which is convenient for processing the two conversion tubes 10 and the experimental tube 9 respectively. The two conversion tubes 10 adopt a gradual structure, which is convenient for docking with the two ends of the experimental tube 9 on the one hand, and can reduce the obstruction to the water flow on the other hand.

[0038] In the present application embodiment:

[0039] Reference Figure 1 and Figure 7 A control host 11 for controlling the actuator 4 is installed on one side of the outer top surface of the second support frame 2. The two are electrically connected to the rangefinder 6 through a wire cable. The rangefinder 6 is convenient for measuring the distance between it and the top surface of the clay soil. Its distance parameter can be set to a constant. When the distance parameter becomes larger, it indicates that the clay soil entering the experimental tube 9 has been washed away, and then the control host 11 is affected by the data change and sends a control signal to the actuator 4 to control the actuator 4 to extend a certain size, so that the clay soil inside the sample tube 5 continues to stably enter the interior of the experimental tube 9, which is used to explore the anti-scouring effect of clay soil.

[0040] In the present application embodiment:

[0041] Reference Figure 1 , 4 and Figure 5 A flow meter 8 is installed below the side of the experimental tube 9 away from the outside of the sample tube 5. The flow meter 8 is symmetrical with the sample tube 5 about the center line of the experimental tube 9. The flow meter 8 is convenient for continuously detecting the water flow changes inside the experimental tube 9 and measuring the changes in water flow velocity during the experiment, so as to explore the scouring test of water flow velocity on different types of clay soils and improve the application scope of the device.

[0042] In the present application embodiment:

[0043] Reference Figure 1 , 5 and Figure 8 A limiting ring 20 for limiting position is installed on one side of the outside of the sample tube 5, and handles 19 are installed on both sides of the outside of the sample tube 5, which are located below the limiting ring 20. The limiting ring 20 is convenient for limiting the installation position of the sample tube 5 to prevent the top of the sample tube 5 from entering the interior of the experimental tube 9 and affecting the test results. At the same time, the two handles 19 are convenient for providing a holding position for rotating the sample tube 5, which is convenient for the user to perform early installation and later disassembly of the sample tube 5. After the disassembly is completed, it is convenient to refill the clay soil sample into the interior of the sample tube 5, which is convenient for repeated experiments to obtain multiple sets of measurement data, ensuring that the measurement structure is more accurate.

[0044] In the present application embodiment:

[0045] Reference Figure 1 , 4 and Figure 5 An internally threaded tube 7 is installed on one side of the experimental tube 9 close to the outside of the sample tube 5. The bottom end of the internally threaded tube 7 fits with the top surface of the limit ring 20, which is convenient for providing an installation position for the sample tube 5, while keeping the sample tube 5 and the rangefinder 6 in a vertical position. The rangefinder 6 can be an ultrasonic rangefinder 6, which is convenient for accurately measuring the distance by continuously generating and receiving ultrasonic waves at the top of the clay soil, and using this as a reference, sending a control signal to the actuator 4, so that the actuator 4 extends, and pushes the clay soil sample to stably and continuously enter the interior of the experimental tube 9.

[0046] Working principle:

[0047] When in use, the clay soil sample is filled into the sample tube 5, and then the sample tube 5 is installed inside the internal threaded tube 7. Then the distance meter 6 measures the distance between it and the top surface of the clay soil sample. When the distance is greater than the set parameter, the control host 11 controls the actuator 4 to move, pushes the piston 18 and the clay soil sample to rise, and allows the clay soil to enter the inside of the experimental tube 9. The water pump 14 is powered on to pump the water inside the first water tank 13 to the inside of the conversion tube 10 on the left. Through the obstruction of the baffle 17, the water flows through the experimental tube 9 at a uniform speed to perform an anti-scouring test on the clay soil sample. At the same time, the return water flows back to the inside of the second water tank 12 along the pipeline and the water inlet pipe 15. After sedimentation, it is re-injected into the inside of the first water tank 13 to continue to participate in the anti-scouring test of the clay soil.

[0048] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
