Description

Technical Field

[0001] This invention relates to the field of debris flow simulation technology, and in particular to a device for simulating debris flow lateral slip in canyons. Background Technology

[0002] Debris flows are mountain disasters caused by natural factors such as rainfall and earthquakes. Their suddenness and destructiveness pose a significant threat to life and property. To study and prevent debris flow disasters, simulation experiments are necessary. These experiments use mathematical descriptions of debris flow movement to model its process and destructive forces. These experiments are typically based on fluid mechanics formulas and utilize computer simulations to study changes in factors such as the scale, velocity, and pressure of debris flows. Through simulation experiments, we can better understand and predict debris flow disasters, improve prevention and mitigation efforts, and reduce the harm and losses caused by debris flows.

[0003] Currently, many devices for simulating debris flows are widely used. For example, common simulated debris flow lateral slip experimental devices include: water tank simulation experimental devices, wind tunnel simulation experimental devices, and single lateral slip experimental devices. During the use of these experimental devices, in order to better understand the experimental data, it is necessary to adjust the tilting slope. The operation is relatively inconvenient during the adjustment process, and the driving equipment needs to apply a large force to complete the tilting operation of the slope frame, which to some extent shortens the service life of the device.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0044] Example 1

[0045] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a device for simulating the lateral slippage of a canyon debris flow, which includes a support unit 100, including a base 101; the base 101 includes a slide rail 101a disposed inside it; a connecting column 400; the connecting column 400 includes a second circular hole 400a disposed inside it; and a limiting unit 500, including a slider 501, a rotating member 502 disposed inside the slider 501, and a limiting member 503 disposed on one side of the rotating member 502.

[0046] Preferably, the slider 501 is welded and fixed to the connecting column 400, and the slider 501 and the connecting column 400 are internally connected, forming a hollow structure. The rotating member 502 is located inside the slider 501 and rotates. The rotation of the rotating member 502 can drive the limiting member 503 to move in the vertical direction. This allows the limiting member 503 to press against the fixed seat 801, causing the ball 802 to move to the outside of the slider 501. The end of the ball 802 contacts the side wall of the first slide rail 101a-2, thereby using rolling instead of sliding to reduce friction. This makes it easier to adjust the angle of the display rack 102 by extending the telescopic rod 300, and to a certain extent, extends the service life of the telescopic rod 300.

[0047] The pushing unit 600 includes a connecting rod 601, a rack 603 disposed at the bottom of the connecting rod 601, a first spring 602 disposed on the outside of the connecting rod 601, and a knob 604 disposed on the outside of the end of the connecting rod 601; the rolling unit 800 includes a fixed seat 801 and a ball bearing 802 disposed on the inside of the fixed seat 801; the slider 501 is disposed inside the slide rail 101a; the connecting post 400 is welded and fixed to the slider 501; the rolling unit 800 is disposed inside the side wall of the slider 501.

[0048] Preferably, the end of the connecting rod 601 is located outside the connecting column 400, and the knob 604 is located outside the connecting rod 601. Pushing the knob 604 can drive the connecting rod 601 to move, causing the rack 603 connected to the bottom of the connecting rod 601 to move, so that the rack 603 can drive the rotating member 502 to rotate. The rotation of the rotating member 502 can drive the limiting member 503 to move, thereby causing the limiting member 503 to drive the fixed seat 801 to move. The limiting member 503 moves upward, so that its end can move to the inside of the slide rail 101a, thereby making it easier for the staff to move the telescopic rod 300 to drive the display rack 102 to rotate.

[0049] During use, in the experiment simulating debris flow lateral slippage, the angle of the flipping display frame 102 needs to be adjusted. At this time, the limiting position on the telescopic rod 300 needs to be released first. Then, the knob 604 is pushed, causing the knob 604 to move the connecting rod 601. The movement of the connecting rod 601 moves the rack 603, which in turn moves the rotating component 502. The movement of the rack 603 causes the rotating component 502 to flip, causing the limiting component 503 to move vertically. The limiting component 503 gradually moves to the inside of the slider 501. The limiting member 503 no longer limits the slider 501; as the limiting member 503 moves, it squeezes the fixed seat 801, causing the ball bearing 802 inside the fixed seat 801 to pass through to the outside of the slider 501. The ball bearing 802 slides inside the first slide rail 101a-2. At this time, the telescopic rod 300 is pushed to move, which drives the slider 501 to move and pushes the display rack 102 to flip. Rolling friction replaces sliding friction, making the telescopic rod 300 move more effortlessly and easier for the operator to operate.

[0050] In summary, the device is simpler and more convenient to use, making it easier for staff to limit the position of the telescopic rod 300. At the same time, when adjusting the angle of the display rack 102, the force required to move the telescopic rod 300 is smaller, which can reduce the burden on operators to a certain extent and make it easier for operators to use during experiments.

[0051] Example 2

[0052] Reference Figures 1 to 7 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes: In the previous embodiment, the device for simulating canyon debris flow lateral slippage includes: a slide rail 101a including a groove 101a-1 disposed at its bottom and a first slide rail 101a-2 disposed on the side wall of the slide rail 101a; a slider 501 including a first circular hole 501a opened on its end face, a bushing 501b disposed inside the slider 501, and a first through hole 501c disposed on the side wall of the slider 501; the slider 501 slides inside the slide rail 101a.

[0053] Preferably, the number of slots 101a-1 is multiple sets, and the multiple sets of slots 101a-1 are equidistantly distributed along the bottom of the slide rail 101a; the multiple sets of slots 101a-1 can facilitate the fixing of the display rack 102 at multiple tilt angles, making it easier for staff to operate; the slide rail 101a-2 cooperates with the ball bearing 802, so that the ball bearing 802 moves along the trajectory direction of the slide rail 101a-2.

[0054] Furthermore, the rotating component 502 includes a connecting shaft 502a, a gear 502b disposed on the top of the connecting shaft 502a, and a fixing sleeve 502c disposed on the outer wall of the connecting shaft 502a; the fixing sleeve 502c includes an arcuate groove 502c-1 formed in its side wall; the end of the connecting shaft 502a is inside the bushing 501b; the connecting shaft 502a rotates along the axial direction of the bushing 501b.

[0055] Preferably, there are two sets of rotating parts 502, which are symmetrically arranged on both sides inside the slider 501. The end of the connecting shaft 502a rotates along the axis of the bushing 501b. The gear 502b and the fixed sleeve 502c are connected by the connecting shaft 502a. The arc-shaped groove 502c-1 is opened on the outer wall of the fixed sleeve 502c, and the interior of the fixed sleeve 502c is a hollow structure.

[0056] Furthermore, the limiting member 503 includes a fixed rod 503a, a push block 503b disposed on the bottom side wall of the fixed rod 503a, a limiting block 503c disposed on the end of the fixed rod 503a, and a guide rod 503d disposed on the side wall of the fixed rod 503a; the fixed rod 503a cooperates with the first circular hole 501a; the guide rod 503d passes through the arc-shaped groove 502c-1 and extends into it; the limiting block 503c passes through the slider 501 and extends into the slot 101a-1; the fixed sleeve 502c rotates to drive the guide rod 503d to move along the trajectory of the arc-shaped groove 502c-1.

[0057] Preferably, the fixing rod 503a is located inside the first circular hole 501a, and the end of the fixing rod 503a passes through the first circular hole 501a and extends to its outer side; the push block 503b has a trapezoidal structure, and as the fixing rod 503a moves, the push block 503b moves, so that the inclined surface of the push block 503b presses against the end of the fixed seat 801, thereby allowing the push block 503b to push the fixed seat 801 to the outside of the slider 501; the guide rod 503d passes through the inner side of the arc groove 502c-1, and the rotation of the fixed sleeve 502c causes the guide rod 503d to move along the trajectory of the arc groove 502c-1, thereby ensuring that the rotating part 502 can move in the vertical direction; so that the limiting block 503c can move into the inside of the slider 501, and the limiting block 503c disengages from the slot 101a-1, thereby releasing the limitation between the slider 501 and the base 101, allowing the operator to move the telescopic rod 300.

[0058] Furthermore, the fixed seat 801 is located inside the first through hole 501c; the fixed seat 801 slides along the inner wall of the first through hole 501c; the ball 802 rolls inside the fixed seat 801; the ball 802 passes through the limiting block 503c and extends to the inner side of the first slide rail 101a-2; the ball 802 cooperates with the first slide rail 101a-2; the end of the fixed seat 801 contacts the push block 503b.

[0059] Preferably, the fixed seat 801 passes through the first through hole 501c and extends to its outer side; during the upward movement of the fixed rod 503a, the push block 503b presses the end of the fixed seat 801 as the fixed rod 503a moves, so that the ball bearing 802 inside the fixed seat 801 passes through to the outer side of the slider 501, so that the ball bearing 802 fits against the inside of the first slide rail 101a-2; at this time, as the slider 501 moves, the ball bearing 802 rolls inside the fixed seat 801, which is more convenient for the staff to move; the number of rolling units 800 is two sets, and the two sets of rolling units 800 are symmetrically arranged on both sides of the slider 501.

[0060] Furthermore, the connecting rod 601 includes a support rod 601a, a connecting block 601b disposed on the side wall of the support rod 601a, and a pressing end 601c disposed at the end of the support rod 601a; the knob 604 includes a second spring 604a disposed therein; the knob 604 is disposed outside the pressing end 601c; the knob 604 rotates along the axial direction of the pressing end 601c; the support rod 601a passes through the second circular hole 400a and extends into it; the connecting post 400 is connected to the slider 501; the rack 603 is located inside the slider 501; the rack 603 meshes with the gear 502b.

[0061] Preferably, the knob 604 is located at the end of the connecting rod 601. Pushing the knob 604 can move the connecting rod 601, which in turn moves the rack 603 connected to its side wall. The rack 603 can rotate the gear 502b. During the movement of the knob 604 under pressure, the end of the knob 604 compresses the second spring 602. The rebound force of the second spring 602 can reset the knob 604, thereby driving the rotating part 502 to reset the limiting part 503. The support rod 601a moves along the trajectory of the second circular hole 400a, so that the connecting rod 601 moves in the horizontal direction.

[0062] Furthermore, a blocking unit 700 is installed at the end of the slider 501. The blocking unit 700 includes a hinge seat 701, a limiting plate 703 disposed inside the hinge seat 701, a protruding plate 702 disposed on one side of the end of the limiting plate 703, and a torsion spring 704 disposed at the end of the limiting plate 703. The limiting plate 703 rotates along the axial direction inside the hinge seat 701. The limiting plate 703 has a "V" shaped structure. The protruding plate 702 contacts the top of the fixing rod 503a. The limiting plate 703 is located on one side of the knob 604.

[0063] Preferably, there are two sets of hinge seats 701, symmetrically arranged on the end face of the slider 501; the limiting plate 703 rotates along the axis of the shaft hole inside the hinge seat 701; the torsion spring 704 facilitates the reset of the limiting plate 703, ensuring that the end of the limiting plate 703 does not affect the movement of the knob 604; the end of the fixing rod 503a contacts the side wall of the protrusion plate 702 during its upward movement, and as the first circular hole 501a moves continuously, it pushes up the protrusion plate 702, causing the other end of the limiting plate 703 to flip and gradually approach the end of the knob 604, at which point the torsion spring 704 is in a compressed state; as 501a extends to its longest length; the limiting plate 703... The end is located at the movement of the knob 604, which can block the knob 604, thereby fixing the position of the limiting member 503 and the ball 802. By rotating the knob 604, the knob 604 rotates along the axis of the pressing end 601c. As the knob 604 rotates, the second spring 604a is gradually compressed. When the longest side of the knob 604 rotates to the vertical position, the two sets of limiting plates 703 are no longer in contact with the end of the knob 604. At this time, the knob 604 can move to one side of the limiting plate 703. At the same time, as the knob 604 moves, the two sets of limiting plates 703 are no longer in contact with the end of the fixing rod 503a. Under the rebound force of the torsion spring 704, the limiting plate 703 gradually moves away from the end of the knob 604.

[0064] During use, the operator needs to adjust the tilt angle between the display rack 102 and the base 101. This adjustment requires moving the telescopic rod 300 to adjust the tilt angle of the display rack 102. Before moving the telescopic rod 300, the slider 501 needs to be released from its fixed position. Pressing the knob 604 causes the connecting rod 601 to move, continuously compressing the first spring 602. The movement of the knob 604 moves the rack 603, which in turn rotates the gear 502b meshing with it, causing the connecting shaft 502a to rotate along the bushing 5. The axis of 01b rotates; the rotation of the connecting shaft 502a drives the fixed sleeve 502c to rotate, and the rotation of the fixed sleeve 502c drives the guide rod 503d to move along the trajectory of the arc groove 502c-1. The guide rod 503d drives the fixed rod 503a to move vertically; the fixed rod 503a moves along the inner wall of the first circular hole 501a; the movement of the fixed rod 503a drives the push block 503b and the limiting block 503c to move; the limiting block 503c moves away from the inside of the slot 101a-1; thereby releasing the fixation between the slider 501 and the base 101; at the same time, the movement of the push block 503b... The end of the fixed seat 801 is pressed, and as the push block 503b rises continuously, the fixed seat 801 is pressed along the inner wall of the first through hole 501c to the outside of the slider 501; this causes the outer wall of the ball 802 to be tightly attached to the first slide rail 101a-2; thus, when the slider 501 is moved, the rolling of the ball 802 inside the fixed seat 801 reduces friction, making it easier for the operator to move the slider 501 with less effort; as the fixed rod 503a moves upward continuously, the end of the fixed rod 503a pushes up the protrusion plate 702, causing the limiting plate 703 to move along the hinge seat 701. The internal shaft hole moves in the direction of movement; when the limiting plate 703 flips to one side of the end of the knob 604, the fixing rod 503a extends to the top; at this time, the hand pressing the knob 604 is released, and under the rebound force of the first spring 602, the end of the knob 604 can be pressed against the end of the limiting plate 703; at this time, the limiting plate 703 can limit the knob 604, thereby ensuring that the bottom of the limiting block 503c is located inside the slider 501; the ball 802 is pressed against the inner wall of the first slide rail 101a-2; this makes it convenient for the staff to push the telescopic rod 300 to move and adjust the flip angle of the display rack 102;

[0065] After the display rack 102 is rotated to the appropriate angle, the position of the telescopic rod 300 and the base 101 need to be fixed. Rotate the knob 604 so that it rotates along the axis of the pressing end 601c. As the knob 604 rotates, the second spring 604a is gradually compressed. When the knob 604 rotates to the notch between the two sets of limiting plates 703, the limiting plates 703 no longer limit the knob 604. Under the rebound force of the first spring 602, the knob 604 is pushed out. As the knob 604 moves, it drives the rack 603 to move, thereby causing the fixing rod 503a to reset. At this time, the fixing rod 503a drives the limiting block 503c to move downward. The limiting block 503c passes through the slider 501 and extends to its outer side to cooperate with the slot 101a-1. This can fix the base 101 and the slider 501. At the same time, the ball 802 is no longer squeezed by the inner wall of the first slide 101a-2. As the end of the fixing rod 503a moves downward, the protrusion 702 is no longer squeezed by the fixing rod 503a. Under the rebound force of the torsion spring 704, it drives the limiting plate 703 to reset. This makes the limiting plate 703 gradually move away from the knob 604 and no longer obstruct the movement trajectory of the knob 604.

[0066] In summary, by cooperating with the limiting unit 500 and the rolling unit 800, the present invention allows the ball bearing 802 to be tightly pressed against the inner side of the first slide rail 101a-2. The rolling friction between the ball bearing 802 and the fixed seat 801 replaces the sliding friction between the slider 501 and the slide rail 101a, reducing friction and thus reducing the force required to move the telescopic rod 300, thereby alleviating the workload of the operator to some extent. At the same time, the limiting member 503 can fix the position of the telescopic rod 300, thereby fixing the angle at which the display rack 102 is flipped, making it easier for staff to conduct experiments.

[0067] Example 3

[0068] Reference Figures 1-4 This is the third embodiment of the present invention, which differs from the previous two embodiments in that it includes: a slope unit 200, including a slope frame 201 and a support wheel 202 disposed at the end of the slope frame 201; a telescopic rod 300; the support unit 100 also includes a display rack 102; the display rack 102 includes a second ball bearing 102a disposed therein; the display rack 102 is adapted to the slope frame 201; and the telescopic rod 300 is fixedly connected to the connecting column 400.

[0069] Furthermore, the support wheels 202 are symmetrically arranged at both ends of the slope frame 201, providing support for the slope frame 201. When the slope frame 201 moves along the interior of the display rack 102, the support wheels 202 ensure that the slope frame 201 does not become unbalanced due to gravity. During the experiment, a shower head is installed above the display rack 102 to simulate natural rainfall, allowing for better data collection. The telescopic rod 300 supports the display rack 102, ensuring that the slope frame 201 remains within the display rack 102. Simultaneously, by adjusting the angle of the display rack 102, different slope inclinations can be simulated, facilitating comparative experiments.

[0070] Preferably, the slope frame 201 includes a storage tank 201a disposed inside it, and a second slide rail 201b disposed on the side wall of the slope frame 201; the second slide rail 201b cooperates with the second ball bearing 102a; the number of storage tanks 201a is multiple sets; the multiple sets of storage tanks 201a are distributed in a rectangular array; the storage tanks 201a are filled with soil of different textures; the end of the telescopic rod 300 is hinged and rotated with one end of the display rack 102; the base 101 is hinged and rotated with the other end of the display rack 102; the change in the length of the telescopic rod 300 causes the angle of inclination of the display rack 102 to change.

[0071] Preferably, the slope frame 201 has multiple storage slots 201a inside; the storage slots 201a contain soils with different characteristics that are separated from each other; by pulling the slope frame 201 to slide inside the display rack 102, the type of soil inside the slope frame 201 on the display rack 102 can be changed; the surface of the display rack 102 has display spaces to facilitate the staff to distinguish the boundaries; the display rack 102 is hinged to the base 101, and the end of the telescopic rod 300 is also hinged to the display rack 102, which allows the display rack 102 to be flipped, thereby achieving the purpose of adjusting the flip angle of the display rack 102; this makes it easier for the staff to conduct experiments.

[0072] Debris flow refers to a geological phenomenon in which water carries a large amount of particulate matter and moves rapidly over a long distance in a short period of time; it is a short-lived, rapid water flow that occurs in mountainous areas and carries a large amount of mud, sand and rocks. The properties and characteristics of the canyon soil have a significant impact on the formation and development of debris flows in canyons.

[0073] For example, alkaline soil areas have a pH > 7.0 and abundant rock weathering colluvium, while acidic soil areas have a pH < 7.0 and looser solid matter. The presence of vegetation in the soil makes the soil more cohesive, while the absence of vegetation in the soil creates voids. Therefore, when simulating debris flow lateral slips in canyons, it is necessary to conduct simulation experiments on slopes with different soil properties.

[0074] In use, the operator fills the storage tank 201a with soil of different properties. Then, during the experiment, the slope frame 201 can be moved by pulling it, thereby moving the soil of different properties inside the slope frame 201 into the display rack 102. This makes it more flexible and convenient for the operator to operate. During the movement of the slope frame 201, the second slide rail 201b and the second ball bearing 102a cooperate to make the slope frame 201 move more effortlessly inside the display rack 102. When adjusting the tilt angle of the display rack 102, the movement of the telescopic rod 300 can cause the display rack 102 to flip along the hinge, thereby achieving the purpose of flipping the tilt angle. When it is necessary to fix the telescopic rod 300, the limiting member 503 should be inserted into the slot 101a-1 as described above to fix the slider 501 and the base 101.

[0075] In summary, the device features a slope frame, a display stand, and rain sprinklers. The slope frame, loaded with different types of soil, is slidably mounted on the display stand. By moving the slope frame along the display stand, the type of soil below the rain sprinklers can be changed, thus quickly simulating the conditions of slopes with different soil properties during debris flows. The device is simple to operate and produces significant results.
