Description

Technical Field

[0001] The utility model relates to the technical field of reservoir bank slope deformation test, in particular to a test simulation device for reservoir bank slope deformation image monitoring. Background Art

[0002] The high slopes of the reservoir bank are often characterized by high and steep slopes, complex slope shapes, high slope stress levels, and complex deformation evolution history. Monitoring the deformation of high slopes is an important means of checking the stability of the reservoir bank and a major means of disaster warning. The existing methods of monitoring the high slopes of the reservoir bank are mainly to use professional instruments or traditional tools for manual close-contact direct observation. Such traditional methods have disadvantages such as low efficiency, limited data, and no guarantee of instrument survival rate. Many deformations cannot be discovered in time. In recent years, measurement methods such as distributed fiber optic sensing technology have emerged, but they have not been widely used due to problems such as high cost and high professional difficulty. In contrast, the use of drone images to monitor the deformation of high slopes on the reservoir bank has various advantages.

[0003] The use of drone images as a non-contact method to monitor high slope deformation can effectively reduce the risks in the monitoring process and efficiently obtain a large amount of image data. Combined with the subsequent analysis and processing of data using computer algorithms, the accuracy of the results is also greatly improved. Observing early deformation through drone images can reserve a lot of time for disaster handling and effectively protect people's lives and property. To achieve these purposes, firstly, a test device for realizing the deformation of high slopes of reservoir banks and a complete set of simulation methods for realizing the deformation of high slopes of reservoir banks are constructed indoors according to the common deformation modes of high slopes of reservoir banks. Therefore, the utility model disclosed by patent number: CN202310887836.7 provides a reservoir bank slope simulation test device and a test method, which belong to the field of reservoir bank model technology, wherein the reservoir bank slope simulation test device includes a vibration simulation base, including two bearing platforms arranged at intervals, each bearing platform is connected to at least one driving part; each bearing platform is respectively provided with a sub-box, and the two sub-boxes are connected by a deformable part to enclose a test box with an upward opening, and the test box is used to load the reservoir bank slope model, and the positive projection of the deformable part on the vibration simulation base does not exceed the interval area between the two bearing platforms. The reservoir bank slope simulation test device provided by the present application can simulate the multi-point earthquake excitation effect of reservoir-induced earthquake on the reservoir bank slope by setting a bearing platform to vibrate different sub-boxes, so as to facilitate the model analysis of the reservoir bank slope; this technical solution is mainly used to explore the changes of the reservoir bank slope under earthquake conditions, and it is difficult to apply to experiments that need to be carried out in different environments (temperature changes, precipitation changes) and different slopes. At the same time, in this model, the actual effect of the vibration simulation matrix needs to be verified, and it may not easily cause obvious changes in the slope; conventional reservoir bank slope deformation does not occur immediately, but only breaks out after many disturbances accumulate, but this device cannot simulate a long disturbance process, and the research on the weak deformation period is insufficient; secondly, the patent number: CN202310733498.1 provides a dangerous rock destruction instability movement characteristic simulation test device, which involves the field of geological deformation monitoring technology. The dangerous rock destruction instability movement characteristic simulation test device includes: a dangerous rock destruction mode simulation test component and an instability movement characteristic simulation test component. According to the simulation test device of the embodiment of the present application, the dangerous rock failure mode simulation test component is used to study the dangerous rock failure mode, and by monitoring the seismic dynamic response and slope deformation at different parts and elevations of the slope, the deformation failure mode and collapse mechanism of the rock slope containing fractures are revealed; the unstable motion characteristic simulation test component can obtain the motion trajectory of the entire process of falling rocks through calculation, and simultaneously record the speed, total energy, bounce height and falling rock accumulation area at each time point of the fall.This technical solution simulates the impact of rockfall characteristics and changes in slope materials on the trajectory of rockfall. It is mainly used to record and analyze deformation conditions after slope deformation occurs. However, it cannot simulate the formation and change of deformation, and cannot effectively monitor and warn of deformation formation under different conditions. The entire equipment is too large and complex to operate. The material cost and technical difficulty are very high, and it is not easy to manufacture. Utility Model Content

[0020] like Figures 1 to 4As shown, a test simulation device for image monitoring of reservoir bank slope deformation includes a base plate 1, a first acrylic box 2, a second acrylic box 3, a drone 4 and a fluorescent lamp. The first acrylic box 2 and the second acrylic box 3 are both slidably arranged on the base plate 1, and the distance between the first acrylic box 2 and the second acrylic box 3 can be adjusted. The top of the first acrylic box 2 and the top of the second acrylic box 3 are both formed with a slope. The side walls of the first acrylic box 2 and the second acrylic box 3 are penetrated with a plurality of small holes 5. A water bag 6 is arranged in the first acrylic box 2 and / or the second acrylic box 3. The water outlet of the water bag 6 is connected to a water pipe 7, which is led to the outside. A valve is arranged on the water pipe 7 to control the conduction of the water pipe 7. On and off, the fluorescent lamp adjusts the temperature of the soil by irradiation, and the drone 4 is used to capture the surface deformation of the reservoir bank slope model during the test. A plurality of acrylic boxes are set on the bottom plate 1 for comparative experiments, changing the influencing parameters, and recording the deformation of the reservoir bank slope under different parameters. Preferably, two acrylic boxes are set, namely the first acrylic box 2 and the second acrylic box 3. Soils of different quantities, densities, and slopes are filled therein, and concrete is sprayed after the soil is filled to simulate the reservoir bank slope in different situations. The temperature of the soil is adjusted by the fluorescent lamp to create the effect of different temperature environments. Water is injected into the interior through the small hole 5 to change the humidity of the soil and study the influence of different humidity environments on the deformation of the reservoir bank slope. The collapsed volume of the soil is accurately controlled by the drainage of the water bag 6 to achieve the purpose of recording the slope deformation step by step. The drone 4 is equipped with a high-precision airborne camera to take pictures and capture the surface deformation of the reservoir bank slope model during the test. Before the start of the test, concrete is sprayed evenly on the surface of the reservoir bank slope model to cover the surface of the reservoir bank slope model and shoot the initial state of the model surface from multiple angles. Then, by changing factors such as ambient temperature, soil moisture, soil density, and the distance between the two acrylic boxes, or using the water bag 6 drainage method to make the slope deform, set the drone to take a picture every 2 seconds to ensure that enough test photos are obtained during the entire test process to ensure the precision and accuracy of the test. When the surface of the slope model shows visible deformation, the test ends; in summary, it can more accurately simulate the deformation of the reservoir bank slope under different slopes, different temperatures, different soil conditions, etc., thereby reflecting the micro-changes on the surface of the reservoir bank slope model and predicting whether a disaster will occur. The device materials are simple and easy to obtain, low cost, and convenient for repeated experiments; and it is easy to disassemble and assemble, and easy to carry and lay out; preferably, the diameter of the small hole 5 is 0.5-1.0cm.

[0021] Furthermore, if Figure 2 and Figure 3As shown, the first acrylic box 2 includes a rectangular box body 8 and a slope box body 9. The slope box body 9 is detachably installed on the top of the rectangular box body 8. The slope of the first acrylic box 2 is formed on the top of the slope box body 9. There are multiple slope box bodies 9. The top surface slopes of the multiple slope box bodies 9 are different, which are used to study the influence of soils with different slopes on the surface deformation of the reservoir bank slope model. By installing slope box bodies 9 with different slopes on the rectangular box body 8 to adjust the top surface slope of the first acrylic box 2, it is convenient to fill the soil in the first acrylic box 2 to manufacture reservoir bank slopes with different slopes. Similarly, the second acrylic box 3 adopts the same combination to adjust the slope of the top surface.

[0022] Furthermore, if Figure 3 As shown, a socket 10 is provided on the top of the rectangular box body 8, and an insert block 11 is fixed on the bottom of the slope box body 9. The insert block 11 is inserted into the socket 10. The connection between the slope box body 9 and the rectangular box body 8 is completed by the cooperation of the insert block 11 and the socket 10. The connection is simple and fast.

[0023] Furthermore, if Figure 2 and Figure 3 As shown, a rubber sheet 12 is fixed to the side wall of the plug block 11. The rubber sheet 12 is interference fit in the socket 10 through compression deformation. The thickness of the rubber sheet 12 gradually decreases from top to bottom. The structure of the second acrylic box 3 is the same as that of the first acrylic box 2. Since the soil will vibrate during collapse or deformation, in order to ensure the connection stability between the slope box body 9 and the rectangular box body 8 so as not to affect the accuracy of the test, it is necessary to improve the connection strength between the slope box body 9 and the rectangular box body 8. The connection strength between the slope box body 9 and the rectangular box body 8 is improved by providing the rubber sheet 12. During the insertion of the rubber sheet 12 into the socket 10, it will be gradually squeezed and deformed, so that the rubber sheet 12 is interference fit in the socket 10, thereby increasing the friction between the slope box body 9 and the rectangular box body 8, thereby increasing the connection strength, and maintaining the stability of the slope box body 9 during the test so as not to affect the test results.

[0024] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, a T-shaped slide rail 13 is fixed on the bottom plate 1, and a T-shaped slide groove 14 is provided at the bottom of the first acrylic box 2 and the bottom of the second acrylic box 3. The T-shaped slide rail 13 is adapted to the T-shaped slide groove 14, so that the first acrylic box 2 and the second acrylic box 3 can move in the horizontal direction to adjust the distance therebetween, while limiting the freedom of the first acrylic box 2 and the second acrylic box 3 in the height direction to ensure stability.

[0025] Furthermore, if Figure 1As shown, the side walls of the first acrylic box 2 and the side walls of the second acrylic box 3 are both threadedly connected with bolts 15, and the bolts 15 pass through the T-shaped slide groove 14 and abut against the side walls of the T-shaped slide rail 13. When the adjustment is completed, the bolts 15 are tightened, and the tail of the bolts 15 abuts against the T-shaped slide rail 13 to lock the positions of the first acrylic box 2 and the second acrylic box 3 without affecting the test results.
