Description

Technical Field

[0001] The invention relates to the technical field of simulation test equipment, and in particular to a simulation device for mountain torrents and mud-rock flows. Background Art

[0002] In the summer monsoon period, when high-altitude mountainous areas encounter continuous rainfall or rainstorms, continuous heavy rainfall will cause flash floods and mud-rock flows. Flash floods and mud-rock flows are sudden, destructive, and fast-moving, and can cause serious damage to nearby activity sites, transportation routes, engineering equipment, mountains, etc. in a very short period of time. Therefore, in order to reduce the losses caused by flash floods and mud-rock flows, timely monitoring and forecasting are of utmost importance.

[0003] Due to the suddenness and rapid movement of mountain torrents and debris flows, it is difficult to collect on-site data during the disaster. Therefore, most of the research on debris flow monitoring technology is based on simulation tests conducted after the disaster occurs, based on the background of the disaster, in order to collect data for studying its physical characteristics of movement.

[0004] A typical mountain torrent debris flow simulation test is conducted in a slideway that is 10m long, 0.6m high, and 0.8m wide. The slideway is hoisted into the air at both ends by a hoisting device. During the simulation, the height of the two ends is adjusted by the hoisting device to change the slope of the slideway. During the test, clay (usually kaolin), sand, and water are mixed in a certain proportion to form mud. The mixed mud is injected from the top of the slideway, and the mud flows downward along the inner wall of the slideway. The mud is captured and photographed by a high-speed camera during its flow, and the movement physical characteristics of the debris flow are studied based on the collected data.

[0005] In the prior art, the slide used in the flash flood mudslide simulation test is usually composed of an external support and an internal lining. The internal lining is usually composed of multiple plates of the same specifications. The plates are laid inside the external support to form a complete slide. In order to simulate the roughness of the natural environment, anti-skid patterns are also provided on the surface of the plates. However, when actually conducting simulation tests, in order to reduce the errors in the test data, it is necessary to conduct multiple tests repeatedly to ensure the accuracy of the obtained data. After each test, in order to prevent the residual mud in the slide from affecting the test process, the slide needs to be cleaned before the next test can be carried out. However, the anti-skid patterns on the surface of the plates will cause a large amount of mud to remain in the patterns. The staff needs to use cleaning tools to repeatedly scrub the patterns of the plates to ensure that there is no residue on the surface of the plates. Therefore, the cleaning process will take a lot of time, affecting the efficiency of the test. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figure 1-Figure 8 A simulation device for mountain torrents and mud-rock flows comprises a support beam 4, on which a plurality of U-shaped support plates 5 are fixedly connected at equal intervals, a plurality of slideway structures 6 are placed inside the support plates 5, two beams 1 are suspended in parallel above the support plates 5, a first electric hoist 101 and a second electric hoist 102 are fixedly connected to the beam 1 at intervals, one end of the support beam 4 is connected to the output end of the first electric hoist 101, and the other end of the support beam 4 is connected to the output end of the second electric hoist 102.

[0037] After being energized, the first electric hoist 101 and the second electric hoist 102 can drive the two ends of the support beam 4 to move vertically, thereby adjusting the height of the two ends of the support beam 4. When conducting a simulation test, the slope of the mud sliding can be adjusted by changing the height of the two ends of the support beam 4 to simulate a natural environment with different slopes.

[0038] The support beam 4 and the pallet 5 together constitute an external bracket for supporting the slide structure 6, and each slide structure 6 exists independently. When conducting actual simulation tests, the test personnel lay the slide structure 6 in the external bracket formed by the support beam 4 and the pallet 5 as needed, and the length of the external bracket is much larger than the laying length of the slide structure 6.

[0039] For example: in actual use, the length of the external support formed by the support beam 4 and the support plate 5 is generally more than 15m, and the length of the slide structure 6 required for laying in general tests is about 10m. After the slide structure 6 is laid on the external support, there will be a vacant part at both ends of the external support, and the connection points of the first electric hoist 101 and the second electric hoist 102 with the external support are located on the ends of the support beam 4. There is a sufficient distance between the laid slide structure 6 and the two electric hoists. Therefore, the two electric hoists will not interfere with the slide structure 6 when it is flipped.

[0040] The state shown in the drawings of the specification is in the preparation stage before the test is carried out. When the test is actually carried out, the slide structure 6 will be subtracted, and the slide structure 6 at both ends of the external bracket will be removed. After each test is completed, the logistics personnel will reinstall the removed slide structure 6 into both ends of the external bracket to prevent the slide structure 6 from being lost. In this way, in each test, the test personnel only need to subtract the slide structure 6 and can use it directly.

[0041] like Figure 7-Figure 13As shown, the slideway structure 6 includes a first hinged rod 10, a second hinged rod 19 and a return spring 20. One end of the first hinged rod 10 is fixedly connected to a fixed shaft 11, and a counterweight 7 is fixedly connected to the end of the fixed shaft 11. Two bottom plates 8 are fixedly connected in parallel on both sides of the counterweight 7. A pulley 16 is rotatably installed on the outer wall of the fixed shaft 11. A winch 2 is fixedly connected to one end of the beam 1, and the winch 2 is connected to the end of the lifting rope 3 to retract and release the lifting rope 3. The tail end of the lifting rope 3 passes through the bottom of the pulley 16 and is fixed to the other end of the beam 1; one end of the second hinged rod 19 is hinged to the end of the first hinged rod 10, and the other end of the second hinged rod 19 is connected to two parallel bottom plates 8 through a connecting structure. The side plates 9 are arranged therebetween, and a support member 33 is fixedly connected between the two side plates 9 to ensure that the spacing between the two side plates 9 does not change. The connection structure includes a sliding seat 21 with a T-shaped groove inside, and the sliding seat 21 is fixedly connected to the side plate 9. The end of the second hinged rod 19 is fixedly connected to a mounting groove 23, and an internal threaded tube 25 is rotatably installed in the mounting groove 23. Both ends of the internal threaded tube 25 are threadedly fitted with a screw rod 22, and the end of the screw rod 22 is fixedly connected to a clamping block 24, and the clamping block 24 is slidably fitted in the T-shaped groove of the sliding seat 21; one end of the return spring 20 is rotatably connected to the outer wall of the first hinged rod 10, and the other end of the return spring 20 is rotatably connected to the outer wall of the second hinged rod 19.

[0042] like Fig.14 As shown, in a normal state, the first hinge rod 10 and the second hinge rod 19 are in the same straight line under the elastic force of the return spring 20, and the bottom plate 8 and the side plate 9 are also in a horizontal state parallel to each other.

[0043] When the bottom plate 8 and the side plate 9 are installed inside the support plate 5, the second hinged rod 19 rotates 90 degrees on the first hinged rod 10 to make the side plate 9 and the bottom plate 8 perpendicular to each other. At this time, the perpendicular side plates 9 and bottom plate 8 are slid into the inside of the support plate 5, and multiple slide structures 6 are connected end to end to form a slide for mud flow.

[0044] When the winch 2 is working, it will reel in or unwind the suspension rope 3, wherein:

[0045] When the winch 2 reels in the hoisting rope 3, the hoisting rope 3 will rise. During the rising process, the hoisting rope 3 will use the pulley 16 as a force point to pull the slide structure 6 upward from the support plate 5. When the slide structure 6 is higher than the support plate 5, under the elastic force of the return spring 20, the mutually perpendicular side plates 9 and the bottom plate 8 will return to a horizontal state parallel to each other under normal conditions.

[0046] like Fig.14 As shown, when the winch 2 releases the suspension rope 3, the suspension rope 3 no longer applies an upward force to the slideway structure 6 through the pulley 16. Under the action of the gravity of the counterweight block 7 and the slideway structure 6 itself, the side plate 9 and the bottom plate 8 will sink back into the interior of the support plate 5 in a mutually perpendicular state.

[0047] like Figure 7-Figure 12 As shown, a ratchet 13 is sleeved on the outside of the fixed shaft 11, a spring 12 is provided between the inner wall of the ratchet 13 and the fixed shaft 11, a ring gear 14 is rotatably installed on the outside of the ratchet 13, a pawl 15 is rotatably installed inside the ring gear 14, the pawl 15 matches the ratchet 13, a driving structure is provided at the bottom of the support plate 5 to rotate the ring gear 14, the driving structure includes a plurality of connecting rods 31, a connecting rod 31 is fixedly connected between two adjacent support plates 5, a notch 32 is provided on one side of the connecting rod 31, a guide rod 28 is slidably fitted in the notch 32, a limiting block 30 is fixedly connected to the bottom end of the guide rod 28, a rack 26 is fixedly connected to the top end of the guide rod 28, the rack 26 matches the ring gear 14, a positioning pin 29 is fixedly connected to the outer wall of the guide rod 28, and the positioning pin 29 is located above the notch 32.

[0048] like Fig.10 As shown in the figure, during the process of the slide structure 6 being pulled upward from the support plate 5, the ring gear 14 will also move upward. Due to the cooperation between the pawl 15 and the ratchet 13, the ring gear 14 and the ratchet 13 are equivalent to a fixed connection during the rising process of the ring gear 14, and the elastic force required for the deformation of the mainspring 12 is much greater than the gravity of the rack 26 and the guide rod 28. Therefore, during the rising process of the ring gear 14, the rack 26 will be driven to move upward together, and the upward movement of the rack 26 will drive the guide rod 28 to move upward in the slot 32 until the limit block 30 at the bottom end of the guide rod 28 abuts against the bottom surface of the slot 32.

[0049] After the limit block 30 abuts against the bottom surface of the notch 32, the ring gear 14 continues to move upward while the rack 26 stops moving upward. At this time, the ring gear 14 moves upward relative to the rack 26. The relative movement between the ring gear 14 and the rack 26 causes the ring gear 14 to rotate. The rotation of the ring gear 14 charges the mainspring 12 through the ratchet 13.

[0050] like Fig.14 As shown, when the ring gear 14 moves to the highest point of the rack 26, it stops moving. At this time, under the elastic force of the reset spring 20, the bottom plate 8 and the side plate 9 are reset to normal. During this process, the elastic potential energy stored in the mainspring 12 will be released. The energy released by the mainspring 12 will drive the fixed shaft 11 to rotate 180 degrees. The rotation of the fixed shaft 11 by 180 degrees will drive the first hinge rod 10 and the second hinge rod 19 to rotate synchronously, so that the bottom plate 8 and the side plate 9 located at the top move to the bottom, and the bottom plate 8 and the side plate 9 originally located at the bottom move to the top.

[0051] After the upper and lower bottom plates 8 and side plates 9 are swapped, the winch 2 releases the suspension rope 3 to allow the slideway structure 6 to sink into the support plate 5 under the action of gravity. At this time, the inner and outer walls of the slideway structure 6 will be swapped. The original outer wall is now located inside the slideway structure 6 for mud to flow, and the original inner wall is now located outside the slideway structure 6. At this time, it is only necessary to use a high-pressure water gun to flush the outer wall of the slideway structure 6. Under the action of gravity, the mud attached to the anti-slip stripes will be easily flushed out to complete the cleaning work.

[0052] like Fig.13 As shown, a connecting member 17 is rotatably mounted on the outside of the fixed shaft 11 , a slider 18 is fixedly connected to one side of the connecting member 17 , a sliding groove 34 is provided on the outer wall of the rack 26 , and the slider 18 is slidably fitted in the sliding groove 34 .

[0053] The slider 18 cooperates with the slide groove 34 to guide the slide structure 6 to prevent the slide structure 6 from being misplaced during movement.

[0054] like Figure 7 and Figure 8 As shown, an anti-skid pad 27 is provided on the surface of the rack 26, and the anti-skid pad 27 rests on the outer wall of the side plate 9. The anti-skid pad 27 limits the side plate 9 by means of friction force to prevent the elastic potential energy of the mainspring 12 from being released during the contact between the anti-skid pad 27 and the side plate 9; when the ring gear 14 is located at the highest point of the rack 26, the anti-skid pad 27 will also separate from the side plate 9 to allow the mainspring 12 to release energy.

[0055] Working principle and workflow: Figure 3 For example, after a simulation test is completed:

[0056] Start the winch 2, the winch 2 reels the lifting rope 3, the lifting rope 3 will rise, and the lifting rope 3 will use the pulley 16 as a force point during the rising process, so that the slideway structure 6 is pulled upward from the support plate 5;

[0057] When the slideway structure 6 is pulled upward from the support plate 5, the ring gear 14 will also move upward. Due to the cooperation between the pawl 15 and the ratchet 13, the ring gear 14 and the ratchet 13 are equivalent to being fixedly connected during the upward process of the ring gear 14. The elastic force required for the deformation of the mainspring 12 is much greater than the gravity of the rack 26 and the guide rod 28. Therefore, during the upward process of the ring gear 14, the rack 26 will be driven to move upward together. The upward movement of the rack 26 will drive the guide rod 28 to move upward in the notch 32 until the limit block 30 at the bottom end of the guide rod 28 abuts against the bottom surface of the notch 32.

[0058] After the limit block 30 abuts against the bottom surface of the notch 32, the ring gear 14 continues to move upward while the rack 26 stops moving upward. At this time, the ring gear 14 moves upward relative to the rack 26. The relative movement between the ring gear 14 and the rack 26 causes the ring gear 14 to rotate. The rotation of the ring gear 14 charges the mainspring 12 through the ratchet 13.

[0059] like Fig.14 As shown, when the ring gear 14 moves to the highest point of the rack 26, the winch 2 is turned off. At this time, the bottom plate 8 at the bottom of the slide structure 6 is higher than the support plate 5. Under the elastic force of the reset spring 20, the bottom plate 8 and the side plate 9 are reset to normal. During this process, the elastic potential energy accumulated in the spring 12 will be released. The energy released by the spring 12 will drive the fixed shaft 11 to rotate 180 degrees. The rotation of the fixed shaft 11 by 180 degrees will drive the first hinge rod 10 and the second hinge rod 19 to rotate synchronously, so that the bottom plate 8 and the side plate 9 located at the top move to the bottom, and the bottom plate 8 and the side plate 9 originally located at the bottom move to the top, so that the bottom plate 8 and the side plate 9 constituting the inner wall and the outer wall of the slide structure 6 are swapped.

[0060] After the positions of the bottom plate 8 and the side plate 9 are swapped, the winch 2 is started again, and the winch 2 pays out the lifting rope 3. Under the action of the gravity of the counterweight block 7 and the slide structure 6 itself, the slide structure 6 sinks back into the support plate 5. At this time, the inner and outer walls of the slide structure 6 will be swapped. The original outer wall is now located inside the slide structure 6 for mud to flow, and the original inner wall is now located outside the slide structure 6. At this time, it is only necessary to use a high-pressure water gun to flush the outer wall of the slide structure 6. Under the action of gravity, the mud attached to the anti-slip stripes will be easily flushed out to complete the cleaning work, and the cleaning process will not affect the mud flow. Simulation tests can be carried out while cleaning to improve the test efficiency.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
