Description

technical field [0001] The invention relates to a teaching auxiliary device, in particular to a geological learning tank experiment teaching auxiliary device. Background technique [0002] Turbidity currents mostly occur in continental margins and are often triggered by factors such as earthquakes, landslides, and storm waves. They are an important mechanism for transporting terrigenous materials from shallow seas to deep seas, and can form turbidity current deposits on continental margins or ocean basins. Strong turbidity currents can break submarine cables and cause harm. Paleoturbidity current deposits formed during geological periods often become oil reservoirs. Therefore, turbidity current deposition, as a unique type of deposition, has been widely valued. [0003] The main manifestation of the discipline of geological sedimentology is expressed through models and literature. In 1950, Kuenen conducted the flume experiment for the first time, proving the possibility a...

AI Technical Summary

Problems solved by technology

[0006] 2. When carrying out flume experiments, the slope length in the process of turbidity flow formation cannot be changed, and it is not convenient to carry out comparative observation experiments on the movement patterns of sedimentary turbidity flow under the same slope and different slope lengths, and it is impossible to realize the turbidity flow under various conditions. In the turbidity flow deposition experiment, the characteristics of the turbidity flow deposition are not comprehensive enough;

[0007] 3. In the traditional geological sedimentology tank experiment, the change of the sedimentary slope is not large, and the movement form of the sedimentary turbidity flow under different slope conditions cannot be carried out. It is not convenient to simulate the sedimentary characteristics under various slopes, and it is not convenient to study the collapse turbidity In order to make the sediment have different slopes, it is necessary to manually change the slope of the water tank, which is very inconvenient to operate, and there are also problems in fixing the water tank after changing the slope;

[0008] 4. At present, when conducting geological sedimentation tank experiments, experiments are carried out in separate tanks, and comparison experiments cannot be performed, and sedimentary characteristics at different flow rates cannot be observed intuitively, which is not convenient for geology teaching and cannot achieve good learning Effect;

[0009] 5. In the traditional geological sedimentation tank experiment, the tank is placed on the left side or on the ground. The tank is made of transparent glass. The ground and the table itself have stripes or colors, which is easy to cause visual confusion and is not conducive to observing the characteristics of the sediment. It is not convenient Research;

[0010] 6. At present, when conducting water tank experiments, it is necessary to slowly pour materials such as sediment into the water tank. If people keep one movement for a long time, it is easy to cause fatigue;

[0011] 7. When the current tank experiment is carried out, the mixing and stirring device for raw materials such as sediment cannot be integrated with the tank, and it is not convenient for materials such as sediment to enter the tank, which increases the preparation process for the tank experiment, wastes time, and is not convenient for the tank experiment. ;

[0012] 8. Most of the stirring process in the existing water tank experiment is manual stirring, with a low degree of automation. Most of the stirring devices are drums, etc., which are easy to cause splashes of materials such as sediment, which need to be cleaned up, which is a waste of time ;

[0013] 9. After the tank test is over, it is very inconvenient to clean the mud-sand mixture, which will waste a lot of time. If it is not cleaned up, it will affect the next tank test;

[0014] 10. The existing stirring device used for sedimentation experiments in geological water tanks pours mud, water and sand together, which is not convenient for mixing materials, and it is easy to cause uneven mixing, slow stirring speed and long stirring time , affecting the conduct of the tank experiment;

[0015] 11. The existing stirring device cannot be fixed during stirring. When the stirring device is tilted, it will cause the splashing of the stirring liquid, which is not conducive to the stirring, and will also increase the cleaning process. It is very inconvenient to clean mud and other substances;

[0016] 12. The existing stirring device can only achieve bottom stirring, which will lead to uneven mixing of mud, water and sand, and increase the stirring time, delaying the tank experiment;

[0017] At present, there is no device that can solve the above problems. In order to better carry out the teaching of geological learning tank experiments, a device that solves the above problems is introduced, which has certain significance for improving the learning effect of geological tank experiment teaching. The research also has great significance and has certain social value
