Description

Technical Field

[0001] The invention belongs to the technical field of rock dissolution simulation, and in particular is a rock dissolution simulation experimental device based on multiple dimensions. Background Art

[0002] The rock dissolution simulation experiment uses the phenomenon of water erosion on the rock surface to create gullies, analogous to the long-term erosion of the earth's surface by rivers and rain in nature, thus revealing that water erosion is an important external force in the formation of landforms such as canyons and river channels, and intuitively showing the law of how water changes rock morphology through mechanical effects such as collision and friction. This experiment aims to illustrate that water, as a carrier of external forces, can gradually change the surface structure through a cycle of erosion, transportation, and deposition. By simulating long-term erosion and observing the change pattern of rock edges becoming less angular and the surface becoming more rounded, we can deduce the typical morphology that may be formed by rocks in natural environments after years of water flow, and further explain the mechanism by which water erosion transforms rocks and the earth's surface.

[0003] For example, the patent application document with application number CN206540809U provides a rock dissolution simulation experimental device of a flow system, which includes a control chamber, a simulation chamber, an air supply unit, a heating unit, a feeding unit and a detection unit. The air supply unit is respectively connected to the control chamber and the simulation chamber and is used to adjust the pressure in the control chamber and the simulation chamber; the heating unit is used to adjust the temperature in the control chamber and the simulation chamber; the feeding unit is respectively connected to the control chamber and the simulation chamber and is used to adjust the pH in the control chamber and the simulation chamber; the detection unit is used to detect at least one of the pressure, temperature and pH in the control chamber and the simulation chamber; the utility model has a simple structure and is easy to install. By setting up a control chamber and a simulation chamber, the control chamber and the simulation chamber are operated under different test conditions, which not only realizes the real-time comparison of the influence of test parameters on test results, but also improves the test efficiency;

[0004] However, when conducting water flow experiments on rocks, specific and effective filtering structures are generally not set in the pipe body. This means that when the water that flushes the rocks flushes the suspended particles such as mud, sand, and rock debris attached to the rock surface, as the water body passively flows through the one-way pipe body, the impurities will be driven and accumulated at the sewer pipe mouth, which will greatly cause the water discharge speed of the pipe body to be forced to slow down or even be blocked, and the water body in the box will gradually rise, affecting the experimental process.

[0016] Preferably, a semi-circular plate is fixedly connected to the outer wall of one end of the two inclined plates, and a plurality of through-hole rod brushes are fixedly connected to the outer wall of the other end of the two semi-circular plates. The plurality of through-hole rod brushes can be intermittently slidably connected to the filter plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention starts the water pump in the main water tank to transmit the water in the main water tank to the secondary water tank through the transmission pipe. The water will then flow down to each rock box through the diversion pipe, pass through multiple water valves on the diversion pipe and control the flow rate of the water flowing into the rock box. By using water with different flow rates, long-term scouring is simulated to observe the changing pattern of rock edges decreasing and the surface becoming rounded, providing some scientific basis for the formation of natural landforms. The transported water can also be replaced with different solutions to study the effects of different solutions on rock dissolution. The water that enters the rock box and accumulates a certain amount of water will also pass through the water valve on the extraction pipe synchronously to be discharged at a specific water flow rate. The water in the extraction pipe will be pumped by the water pump and return to the main water tank again for circular water utilization.

[0019] The present invention drives the water wheel to rotate through the water flowing into the suction pipe, thereby driving the fixed rotating rod and the cam rocker to rotate together, and the rotating cam rocker will rotate flexibly in the sleeve, thereby driving the sleeve to slide on the rod body of the rectangular rod plate. At the same time, the rectangular rod plate and the vertical rod will also be affected by the rotation of the cam rocker, and move vertically up and down under the limitation of the sleeve on the vertical rod. In this way, impurities in the water body can be continuously processed during the experiment. The upward movement of the vertical rod will synchronously drive the two scrapers on the top of the conical block, so that the two scrapers move horizontally in opposite directions at the same time, and will scrape the rock impurities accumulated on the surface of the filter screen plate that is connected at the bottom, thereby repeatedly performing anti-blocking operations.

[0020] The present invention drives the abutment plate to gradually contact one end plate of the inclined plate as the two scrapers translate in opposite directions, and in the continuous pushing process, drives the inclined plate to tilt at an angle on the inner wall of the rock box with the rotating shaft as the axis point, thereby driving the second elastic member to rotate. At the same time, the flipping of the inclined plate drives the semi-circular arc plate and a plurality of through-hole rod brushes to tilt and rotate synchronously. The diameter of each through-hole rod brush is smaller than the diameter of the filter mesh plate. When the through-hole rod brush is passively flipped 90 degrees, it can pass through the filter mesh plate and perform through-hole treatment on the filter holes in the filter mesh plate, thereby avoiding the deposition of particulate matter and the gradual formation of a siltation layer, which leads to a reduction in the pipe diameter or even complete blockage.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides a multi-dimensional rock dissolution simulation experimental device, comprising a main water tank 1, a water pump 11 is fixedly connected to the inner wall of the bottom end of the main water tank 1, a delivery pipe 12 is fixedly connected to the outer wall of one end of the main water tank 1, a secondary water tank 13 is fixedly connected to the pipe body of the other end of the delivery pipe 12, a diversion pipe 14 is fixedly connected to the bottom end of the secondary water tank 13, a rock box 15 is provided on the bottom end pipe body of multiple sections of the diversion pipe 14, the main water tank 1, the secondary water tank 13 and the multiple rock boxes 15 are all fitted with a box cover on the top, the box cover of each rock box 15 is respectively and slidably connected to each section of the diversion pipe 14, and a suction pipe 16 is fixedly connected to the outer wall of the bottom end of each rock box 15, each section of the diversion pipe 14 and each section of the suction pipe 16 are fixedly connected to a water valve 17, and a filter screen 18 is fixedly connected to the top pipe mouth of each section of the suction pipe 16;

[0034] An anti-blocking portion 2 is provided on one side plate of each rock box 15. Each anti-blocking portion 2 includes a water wheel 21 that is rotatably connected to a section of the suction pipe 16. A rotating rod 22 is fixedly connected to one side rod of the water wheel 21, and the rotating rod 22 is provided with a rotating and translational structure.

[0035] The above scheme is adopted: by starting the water pump 11 in the main water tank 1, the water in the main water tank 1 is transmitted to the secondary water tank 13 through the transmission pipe 12, and the water will then flow down through the diversion pipe 14 to each rock box 15, and pass through multiple water valves 17 on the diversion pipe 14 to control the flow rate of the water flowing into the rock box 15. By using water with different flow rates, long-term scouring is simulated, and the changing law of the rock angularity decreasing and the surface becoming rounded is observed, providing some scientific basis for the formation of natural landforms. The transported water can also be replaced with different solutions to study the effects of different solutions on rock dissolution. The water that enters the rock box 15 and accumulates a certain amount of water will also pass through the water valve 17 on the extraction pipe 16 synchronously to be discharged at a specific water flow rate. The water in the extraction pipe 16 will be pumped by the water pump 11 and return to the main water tank 1 again for circular water utilization, and the water flowing down into the extraction pipe 16 will drive the water wheel 21 to rotate.

[0036] The rotation and translation structure includes a cam rocker 23 fixedly connected to one end of the rotating rod 22, a sleeve 24 movably sleeved on the rod body of the cam rocker 23, a sleeve 25 fixedly connected to the top outer wall of the sleeve 24, a rectangular rod plate 26 slidingly connected through the sleeve 25, a vertical rod 27 fixedly connected to the top of the rectangular rod plate 26, a conical block 28 fixedly connected to the top of the vertical rod 27, a sleeve rod 29 slidingly connected to the rod body of the vertical rod 27, a support plate 230 fixedly connected to the top of the rod body of the sleeve rod 29, one end plate of the support plate 230 is fixedly connected to the outer wall of one end of the rock box 15, the outer wall of the conical block 28 can be intermittently fitted and slidably connected to two scrapers 231, and a long rectangular groove is provided on the plate body of one end of the rock box 15 near the bottom.

[0037] The above scheme is adopted: the water wheel 21 rotates, thereby driving the fixed rotating rod 22 and the cam rocker 23 to rotate together, and the rotating cam rocker 23 will rotate movably in the sleeve 24, thereby driving the sleeve 25 to slide on the rod body of the rectangular rod plate 26. At the same time, the rectangular rod plate 26 and the vertical rod 27 will also be affected by the rotation of the cam rocker 23, and move vertically up and down under the limitation of the sleeve rod 29 on the vertical rod 27. The upward movement of the vertical rod 27 will synchronously drive the conical block 28 to push up the two scrapers 231, so that the two scrapers 231 move horizontally in opposite directions at the same time.

[0038] A folding curtain 1 is fixedly connected to the inner walls at both ends of the long rectangular groove, and a folding curtain 2 is also fixedly connected between the two scrapers 231. The upper and lower ends of the folding curtain 1 and the folding curtain 2 are respectively slidably connected to the upper and lower inner walls of the long rectangular groove. The bottom end plates of the two scrapers 231 are half triangle and half arc angle respectively. An elastic member 232 is fixedly connected to the outer wall of the other end of the two scrapers 231, and a connecting plate 233 is fixedly connected to the other end of the two elastic members 232, and one end plate of the two connecting plates 233 is fixedly connected to the outer wall of one end of the rock box 15.

[0039] The above scheme is adopted: the two scrapers 231 move in opposite directions at the same time, which will unfold the folding curtain 2 between the two, and synchronously squeeze the two folding curtains 1 fixed to the inner wall of the long rectangular groove at both ends, and also squeeze the elastic member 232 installed accordingly on the connecting plate 233. The elastic member 232 is specifically a spring, which causes it to deform. The setting of the elastic member 232 is convenient for the subsequent scraper 231 to automatically drive the scraper 231 to reset when there is no force. In the above, when the two scrapers 231 move in opposite directions, they will scrape the rock impurities attached to the surface of the filter screen 18 that is connected at the bottom, so as to avoid affecting the normal downstream of the water body of the filter screen 18, and long-term accumulation, resulting in events that are difficult to clean. Therefore, when the maximum diameter of the conical block 28 contacts the two scrapers 231, it means that the two scrapers 231 have passively pushed the impurities to the edges of both ends of the filter screen 18.

[0040] The two scrapers 231 are fixedly connected to the side walls at the other ends thereof with abutment plates 234, and the plate bodies of the two abutment plates 234 are intermittently fitted and slidably connected with inclined plates 235, and the plate bodies of the two inclined plates 235 are fixedly connected with rotating shafts 236, and the rod bodies of the two rotating shafts 236 are movably sleeved with the inner wall of the other end plate body of the rock box 15, and the outer walls of the rod bodies of the two rotating shafts 236 are jointly and fixedly connected with the inner wall of the other end plate body of the rock box 15 with elastic members 237, and the outer walls of the rod bodies of the two rotating shafts 236 are fixedly connected with the inner wall of the other end plate body of the rock box 15, and the two inclined plates 235 are also fixedly connected to the outer walls at one end thereof with semi-circular plates 238, and the outer walls at the other ends of the two semi-circular plates 238 are fixedly connected with a number of through-hole rod brushes 239, and the several through-hole rod brushes 239 can intermittently slide through the filter screen plate 18.

[0041] The above scheme is adopted: as the two scrapers 231 move in opposite directions, the abutment plate 234 will be driven to gradually contact one end plate of the inclined plate 235, and in the continuous pushing process, the inclined plate 235 will be driven to tilt at an angle on the inner wall of the rock box 15 with the rotating shaft 236 as the axis point, thereby driving the elastic member 237 to rotate. The elastic member 237 is specifically a torsion spring, which causes it to deform. The setting of the elastic member 237 can drive the inclined plate 235 to automatically reset after the inclined plate 235 is no longer under force. At the same time, the flipping of the inclined plate 235 will drive the semi-circular plate 238 and several through-hole rod brushes 239 to rotate simultaneously. The step is tilted and rotated. Each through-hole rod brush 239 is made of natural rubber, which has high elasticity and high wear resistance. It also has a certain hardness. The diameter of each through-hole rod brush 239 is smaller than the diameter of the filter screen plate 18. The existence of the filter screen plate 18 can filter a large amount of mud and sand, as well as the rock debris washed down. The debris itself has a certain volume, so it can be screened 100%. When the through-hole rod brush 239 is passively flipped 90 degrees, it can pass through the filter screen plate 18 and perform through-hole treatment on the filter holes in the filter screen plate 18 to avoid the deposition of particulate matter and the gradual formation of a silt layer, which causes the pipe diameter to shrink or even completely block.

[0042] It should be added that when the through-hole rod brush 239 is passively turned over, there is a certain distance between the through-hole rod brush 239 and the rock box 15 and the scraper 231. Figure 8 As shown, the scraper 231 needs to move a certain distance to contact the inclined plate 235. When the inclined plate 235 is driven to tilt so that the through-hole rod brush 239 can contact the filter screen plate 18, the scraper 231 is almost at the edge of the filter screen plate 18, and the through-hole rod brush 239 is in a state of being in contact with the filter screen plate 18. Figure 8 When the angle is 90 degrees, the scraper 231 will be located directly below the semicircular plate 238;

[0043] During implementation, all of the above-mentioned boxes and tubes are limited on the wall or plate, are firmly fixed, and the rocks are placed on one side of the inner wall of the rock box 15.

[0044] The working principle and use process of the present invention are as follows: by starting the water pump 11 in the main water tank 1, the water in the main water tank 1 is transmitted to the secondary water tank 13 through the transmission pipe 12, and the water will then flow down through the diversion pipe 14 to each rock box 15, and pass through multiple water valves 17 on the diversion pipe 14 to control the flow rate of the water flowing into the rock box 15. By using water with different flow rates, long-term scouring is simulated to observe the change law of the rock angularity decreasing and the surface tending to be rounded, providing some scientific basis for the formation of natural landforms. The transported water can also be replaced with different solutions to study the effects of different solutions on rock dissolution. The water that enters the rock box 15 and accumulates a certain amount of water will also pass through the water valve 17 on the extraction pipe 16 synchronously to discharge at a specific water flow rate. The water in the extraction pipe 16 will be pumped by the water pump 11 and return to the main water tank 1 again for circular water utilization.

[0045] The water flowing into the suction pipe 16 drives the water wheel 21 to rotate, thereby driving the fixed rotating rod 22 and the cam rocker 23 to rotate together, and the rotating cam rocker 23 will rotate flexibly in the sleeve 24, thereby driving the sleeve 25 to slide on the rod body of the rectangular rod plate 26. At the same time, the rectangular rod plate 26 and the vertical rod 27 will also be affected by the rotation of the cam rocker 23, and move vertically up and down under the limit of the sleeve rod 29 on the vertical rod 27. The upward movement of the vertical rod 27 will synchronously drive the conical block 28 to push up the two scrapers 231, so that the two scrapers 231 At the same time, they move horizontally in opposite directions, thereby unfolding the folding curtain 2 fixedly mounted between the two, and synchronously squeezing the two folding curtains 1 fixedly mounted at both ends and the inner wall of the long rectangular groove, as well as squeezing the elastic member 1 232 correspondingly mounted on the connecting plate 233. In the above, when the two scrapers 231 move horizontally in opposite directions, they scrape the rock impurities accumulated on the surface of the filter screen plate 18 connected to the bottom end. When the maximum diameter of the conical block 28 contacts the two scrapers 231, it means that the two scrapers 231 have passively pushed the impurities to the edges of both ends of the filter screen plate 18.

[0046] At the same time, as the two scrapers 231 translate in opposite directions, the abutment plate 234 will gradually contact one end plate of the inclined plate 235, and in the continuous pushing process, the inclined plate 235 will be driven to tilt at an angle on the inner wall of the rock box 15 with the rotating shaft 236 as the axis point, thereby driving the elastic member 237 to rotate. At the same time, the flipping of the inclined plate 235 will drive the semi-circular plate 238 and several through-hole rod brushes 239 to tilt and rotate synchronously. The diameter of each through-hole rod brush 239 is smaller than the diameter of the filter screen plate 18. When the through-hole rod brush 239 is passively flipped 90 degrees, it can pass through the filter screen plate 18 and perform through-hole treatment on the filter holes in the filter screen plate 18 to prevent particulate matter from depositing and gradually forming a silt layer, which leads to a reduction in the pipe diameter or even complete blockage.
