Description

Technical Field

[0001] The utility model belongs to the technical field of avalanche measurement simulation, in particular to an avalanche measurement simulation test device. Background Art

[0002] Avalanche, as a natural disaster driven by gravity, is characterized by potential, suddenness, unpredictability and great destructive power. As the country pays more and more attention to avalanche disasters in the western plateau, it is particularly important to study the dynamic behavior and mechanism of avalanches. Due to the harsh environment of high-altitude and cold areas, field investigations face many challenges. In addition, the causes and mechanisms of these gravity geological disasters often involve multi-scale research such as micro- and macro-scale. The use of geological surveys, field observations, and large-scale outdoor experiments has obvious limitations. At present, small-scale avalanche measurement and simulation test devices play an important role in the field of avalanche dynamics research.

[0003] The operating procedures of some small-scale avalanche measurement simulation test devices are as follows: first, the simulated snow material (such as crushed ice particles or sintered snow) is placed in the storage bin, and then the inclination angle of the avalanche slide is adjusted to the target slope. After the experiment is started, the simulated snow material in the storage bin is released to flow along the slide. During this process, the high-speed camera system records the motion trajectory, velocity distribution and accumulation morphology of the snow flow in full to obtain the dynamic parameters.

[0004] However, in actual avalanche processes, the flow behavior of snow will change significantly with the dynamic changes of terrain slope. The inclination angle of real mountain terrain often presents a nonlinear distribution, and the existing avalanche simulation device only conducts experiments through a single fixed-angle slide, which cannot reproduce the impact of continuous slope changes on the acceleration, deceleration and accumulation of snow flow. This simplification leads to systematic deviations between the dynamic parameters of simulated avalanches and real scenarios, greatly reducing the reliability of experimental data and engineering applicability. Therefore, an avalanche measurement simulation test device is proposed to address the above problems. Utility Model Content

When adjusting the angle, the connecting ends between the telescopic plates 1 9, 2 91, and 3 92 will rotate, and at the same time, they will expand and contract according to their own characteristics. At the same time, the connecting ends of the telescopic plates 1 9, 2 91, and 3 92 and the other end of the telescopic plate 1 9 are provided with a group of slide grooves 94, sliders 95, and rotating rods 97. When adjusting the angle, the slider 95 will slide on the inner wall of the slide groove 94, and the rotating rod 97 will rotate on the side wall of the slider 95. After the adjustment is completed, the gate 10 can be opened to release the material simulating snow inside the storage bin 7. The material simulating snow will flow on the telescopic plates 3 92, 2 91, and 1 9. During the flow process, it can be recorded by the high-speed camera 3. Finally, the material will fall into the middle of the support shell 1. At this time, the scanning modeling mechanism 2 can be used to realize the contactless capture of the erosion and deposition morphology of the material, build a three-dimensional model, and capture physical information in a refined manner.

[0027] Further, such as Figure 1 and Figure 4 As shown, a deposition shell 8 is slidably arranged on the inner wall of the support shell 1; a universal wheel is arranged at the bottom of the deposition shell 8; a limit plate 83 is fixedly connected to the side wall of the support shell 1; a rotating rod 84 is rotatably connected to the side wall of the deposition shell 8; a clamping plate 81 is contacted with the side wall of the limit plate 83; the end of the rotating rod 84 is fixedly connected to the inner wall of the end of the clamping plate 81; a handle 82 is fixedly connected to the side wall of the clamping plate 81. When working, when the simulated material enters the middle part of the support shell 1, it will fall into the interior of the deposition shell 8. After the simulation is completed, when the material inside needs to be processed, it only needs to hold the handle 82 and push the clamping plate 81. Plate 81, at this time, the card plate 81 will drive the rotating rod 84 to rotate on the side wall of the deposition shell 8 until the card plate 81 is separated from the inner wall of the limiting plate 83, and then the deposition shell 8 can be pulled, and the deposition shell 8 will be moved out from the inside of the supporting shell 1 through the universal wheel arranged at the bottom thereof. After the processing is completed, the deposition shell 8 can be pushed into the inner wall of the supporting shell 1. After it is fully pushed in, the card plate 81 is pushed to rotate until the card plate 81 is stuck on the side wall of the limiting plate 83, so that the deposition shell 8 can be stably limited in the middle of the supporting shell 1, so that the material can be transferred quickly, thereby improving the practicality.

[0028] Further, such as Figure 1 and Figure 3 As shown, the side wall of the support plate 4 is slidably connected with a sliding plate 51; the side wall of the sliding plate 51 is fixedly connected with a round rod 52; the outer wall of the round rod 52 is rotatably connected with a gantry lifting frame 5. When working, the overall angle of the support plate 4 can also be adjusted by adjusting the height of the gantry lifting frame 5. The gantry lifting frame 5 is a prior art, and the staff in this field are familiar with its use and operation, so it is not introduced in detail here. When the gantry lifting frame 5 adjusts the height, one end of the support plate 4 will rotate with the support shell 1, and the angle of the support plate 4 will tilt. In this process, the top end of the gantry lifting frame 5 will rotate on the outer wall of the round rod 52, and the connection distance between the sliding plate 51 and the support plate 4 will change, thereby ensuring the smoothness of movement between the structures. This can improve the diversity of the actual angles of the device mode and improve practicality.

[0029] Further, such as Figure 2 and Figure 5As shown, a threaded rod 93 is rotatably connected to the bottom of the baffle 6; the threaded rod 93 is rotatably connected to the bottom of the support plate 4; the threaded rod 93 is threadedly connected to the slider 95. During operation, when adjusting the angle between the telescopic plate 1 9, the telescopic plate 2 91, and the telescopic plate 3 92, the threaded rod 93 can be rotated. At this time, the slider 95 threadedly connected to the outer wall of the threaded rod 93 will move linearly and move on the inner wall of the slide groove 94. The threaded rod 93 and the slider 95 have a self-locking feature, ensuring that the slider 95 will not be displaced when the threaded rod 93 is rotated without using external force, thereby ensuring the stability of each connecting end of the telescopic plate 1 9, the telescopic plate 2 91, and the telescopic plate 3 92.

[0030] Further, such as Figure 6 As shown, a torsion spring 85 is sleeved on the outer wall of the rotating rod 84; one end of the torsion spring 85 is fixedly connected to the inner wall of the end of the clamping plate 81; the other end of the torsion spring 85 is fixedly connected to the side wall of the deposition shell 8. When working, the torsion spring 85 has a certain elasticity. When the clamping plate 81 is rotated, it will drive the torsion spring 85 to twist and deform. When the force on the clamping plate 81 stops, the rotating rod 84 will drive the clamping plate 81 to rotate in the opposite direction for reset through its own elasticity, thereby ensuring the stability of the clamping plate 81 limit and improving the stability of the deposition shell 8 inside the supporting shell 1.

[0031] Further, such as Figure 1 and Figure 4 As shown, the clamping plate 81, the handle 82, the limit plate 83, the rotating rod 84 and the torsion spring 85 are provided in multiple groups; and the multiple groups of clamping plates 81, the handle 82, the limit plate 83, the rotating rod 84 and the torsion spring 85 are symmetrically arranged with the center line of the deposition shell 8 as the axis of symmetry. When working, the stability of the deposition shell 8 installed inside the supporting shell 1 can be improved by setting the multiple groups of clamping plates 81, the handle 82, the limit plate 83, the rotating rod 84 and the torsion spring 85.

[0032] Working principle: the simulated snow material can be placed inside the storage bin 7, and then the inclination angles of the telescopic plate 1 9, the telescopic plate 2 91, and the telescopic plate 3 92 can be adjusted respectively to simulate the various stages of the slope in reality, and the telescopic plate 1 9, the telescopic plate 2 91, and the telescopic plate 3 92 respectively simulate the erosion section, the acceleration section, and the release section, so that the data of the device simulation test is more in line with reality. When adjusting the angle, the connecting ends of the telescopic plate 1 9, the telescopic plate 2 91, and the telescopic plate 3 92 will rotate, and at the same time, they will expand and contract according to their own characteristics. At the same time, the connecting ends of the telescopic plates 1 9, the telescopic plates 2 91, and the telescopic plates 3 92 and the other end of the telescopic plate 1 9 are provided with a set of sliding Groove 94, slider 95, rotating rod 97, and when adjusting the angle, slider 95 will slide on the inner wall of slide groove 94, and rotating rod 97 will rotate on the side wall of slider 95. After the adjustment is completed, gate 10 can be opened to release the simulated snow material inside storage bin 7. The simulated snow material will flow on telescopic plate three 92, telescopic plate two 91 and telescopic plate one 9. During the flow, it can be recorded by the set high-speed camera 3. Finally, the material will fall into the middle part of support shell 1. At this time, the scanning modeling mechanism 2 can be used to realize contactless capture of erosion and deposition morphology of the material, build a three-dimensional model, and capture physical information in a refined manner.

[0033] When adjusting the angles among the telescopic plates 1 9, 2 91 and 3 92, the threaded rod 93 can be rotated. At this time, the slider 95 threadedly connected to the outer wall of the threaded rod 93 will move linearly and move on the inner wall of the slide groove 94. The threaded rod 93 and the slider 95 have a self-locking feature, ensuring that the slider 95 will not be displaced when the threaded rod 93 is rotated without external force, thereby ensuring the stability of the connecting ends of the telescopic plates 1 9, 2 91 and 3 92.

[0034] When the material used in the simulation enters the middle of the support shell 1, it will fall into the interior of the deposition shell 8. After the simulation is completed, when it is necessary to process the material inside, you only need to hold the handle 82 and push the card plate 81. At this time, the card plate 81 will drive the rotating rod 84 to rotate on the side wall of the deposition shell 8 until the card plate 81 is separated from the inner wall of the limiting plate 83. Then you can pull the deposition shell 8, and the deposition shell 8 will move out from the interior of the support shell 1 through the universal wheels set at the bottom of the deposition shell 1. After the processing is completed, the deposition shell 8 can be pushed into the inner wall of the support shell 1. After it is fully pushed in, push the card plate 81 to rotate it until the card plate 81 is stuck on the side wall of the limiting plate 83. In this way, the deposition shell 8 can be stably limited in the middle of the support shell 1, so that the material can be transferred quickly, thereby improving practicality.

[0035] In addition, the overall angle of the support plate 4 can also be adjusted by adjusting the height of the gantry lifting frame 5. The gantry lifting frame 5 is a prior art, and the staff in this field are familiar with its use and operation, so it will not be introduced in detail here. When the gantry lifting frame 5 is adjusted in height, one end of the support plate 4 will rotate between the support shell 1, and the angle of the support plate 4 will tilt. In this process, the top end of the gantry lifting frame 5 will rotate on the outer wall of the round rod 52, and the connection distance between the sliding plate 51 and the support plate 4 will change, ensuring the smoothness of the movement between the structures, which can improve the diversity of the actual angles of the device mode and improve practicality.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
