Description

Technical Field

[0001] The invention relates to the technical field of syn-sedimentary structure experiments, and in particular to a syn-sedimentary structure physical simulation experiment device and method. Background Art

[0002] Synsedimentary structures, also known as syngenetic structures or growth structures, refer to structures developed during the sedimentation process. The structural morphology of synsedimentary structures is generally manifested as intra-basin faults, basin margin faults and fold deformations. Synsedimentary structures are mainly developed in the upper plate of synsedimentary faults in discrete plate boundaries and fault basins with slight intra-plate deformation. Sedimentary simulation is an important experimental means and technical method in sedimentary theoretical research. It can be divided into numerical simulation and physical simulation. Physical simulation is an indoor simulation of the physical process of sediments. By simulating the sedimentary conditions at that time, the deposition process of natural sediments is restored in the laboratory. Synsedimentary structural physical simulation is the simulation of physical processes indoors. The key is the similarity between the prototype and the model. Nowadays, when conducting synsedimentary structural physical simulation experiments in the laboratory, synsedimentary structural physical simulation experimental equipment is needed.

[0003] However, in the prior art, when conducting physical simulation of syn-sedimentary structures, the existing syn-sedimentary structure physical simulation experimental equipment has a simple structure and is usually only capable of conducting one of physical deposition simulation experiments and tectonic movement simulation experiments. The function is relatively single, resulting in inaccurate experimental results. In addition, since physical deposition simulation experiments and tectonic movement simulation experiments cannot be conducted simultaneously, the experimental process cannot meet the actual environmental requirements, the experimental effect is not ideal, and the accuracy of the experimental results is reduced, thereby failing to meet the use requirements. To this end, we propose a syn-sedimentary structure physical simulation experimental equipment and method for solving the above problems. Summary of the invention

By turning on the fluorescent lamp, the light emitted by the fluorescent lamp is irradiated on the surface of the sediment debris particles to simulate the condition of the sediment debris particles being exposed to sunlight, and by turning on different fluorescent lamps, the condition of the sediment debris particles being exposed to sunlight of different intensities can be simulated, and by turning on any fan, the condition of the sediment debris particles being blown by the wind can be simulated, and And by turning on different fans, the wind direction of the silt and debris particles can be changed. By starting the water pump, the clean water in the water tank passes through the water delivery bellows, the water pump, the water outlet pipe, the drainage pipe and finally is discharged from multiple nozzles. The clean water discharged from the multiple nozzles flows on the surface of the silt and debris particles, which can simulate the situation of the river scouring the surface of the silt and debris particles. The clean water in the experimental box flows back to the water tank through the return water bellows after being filtered by the filter, so that the clean water in the water tank can be recycled, which has the effect of saving water resources.

[0018] S2: When conducting a tectonic movement simulation experiment on sediment debris particles, by turning on two pressure sensors and then turning on two electric push rods, the two electric push rods push the corresponding extrusion plates to slide out of the corresponding storage slots, and then use the extrusion force exerted by the two extrusion plates on the sediment debris particles to simulate the horizontal tectonic movement experiment. The two pressure sensors can be used to detect the extrusion force on the sediment debris particles, so that the pressure value is displayed on the display screen of the controller for researchers to watch. By turning on the vibration motor, the vibration force generated by the vibration motor is used to pass The load-bearing plate is used to transfer the force to the sediment debris particles, so as to simulate the vertical tectonic movement experiment. When one vibration motor, two vibration motors or three vibration motors are turned on according to the experimental situation, the vertical vibration force on the sediment debris particles is different, so that the vertical tectonic movement simulation experiment with different strengths can be carried out on the sediment debris particles. Then, by carrying out the horizontal and vertical tectonic movement simulation experiment on the sediment debris particles, the basin faults, basin margin faults and fold deformations occurring in the sediment debris particles can be effectively observed, so as to further improve the experimental effect.

[0019] S3: During the experiment, by performing the operation steps of S1 and S2 at the same time, the physical sedimentation simulation experiment and the tectonic movement simulation experiment can be carried out simultaneously, which can meet the actual environmental requirements as much as possible and improve the accuracy of the experimental results;

[0020] S4: During the experiment, by starting the motor to rotate forward, the motor drives the screw to rotate forward, so that the rectangular slide drives the support inclined plate to move horizontally to the right, the support inclined plate gradually tilts upward, and the support inclined plate pushes the experimental box to gradually tilt upward, the experimental box can be adjusted to different inclination angles to carry out the same sedimentary structure physical simulation experiment on the sediment debris particles, further improving the experimental effect, by starting the motor to rotate reversely, the motor drives the screw to rotate in the opposite direction, so that the rectangular slide drives the support inclined plate to move horizontally to the left, the support inclined plate gradually tilts downward, the support inclined plate pushes the experimental box to gradually tilt downward, and the experimental box can be adjusted back to the horizontal position.

By starting the motor 13 to reverse, the screw rod 11 can be controlled to rotate in the opposite direction, so that the rectangular slide 12 drives the supporting inclined plate 8 to move horizontally to the left, and the supporting inclined plate 8 gradually tilts downward and pushes the experimental box 4 to gradually tilt downward, so that the experimental box 4 can be adjusted back to a horizontal position.
