Description

Technical Field

[0001] The invention relates to the technical field of sedimentation simulation, and in particular to a deep-water sedimentation system formation simulation system. Background Art

[0002] Deepwater sedimentation simulation is a complex geological process that involves multiple factors such as water flow, sediment transport, and sedimentary layer formation. In experimental simulation technology, deepwater sedimentation simulation is usually used to study the deposition laws of sediments, sedimentary layer structure, and related geological processes.

[0003] For example, the Chinese patent publication number is CN108037249A, the publication date is 2018-05-15, and the invention name is: Deep-water sedimentation system formation simulation device. The invention consists of two parts (A) and (B); the (A) is located on one side of the (B); a bottom tie bar (2) is arranged at the bottom of the experimental body (1), a top tie bar (3) is arranged at the top of the experimental body (1), and a movable adjustable triangle iron (7) is arranged on the experimental body (1), and the movable adjustable triangle iron (7) is composed of a plurality of bottom angle steels (7.1) and vertical angle steels (7.2); a water flow velocity meter (6) is installed on the vertical angle steel (7.2).

[0004] In the above technical scheme, a flume experiment is set up to simulate the deep-water sedimentation system. However, in the specific flume experiment, when simulating the turbidity current deposition in deep water, the technical scheme only involves the composition and structural construction of the sedimentation body. However, when the turbidity current is actually deposited in deep water, it will also be affected by peripheral factors of the environmental characteristics associated with it. Therefore, in order to obtain the actual deposition phenomenon of the turbidity current in deep water to obtain the landform before and after deposition and the deposition state parameters, the present invention proposes a deep-water sedimentation system formation simulation system. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a deep-water sedimentation system formation simulation system, which can effectively solve the problem that turbidity currents are affected by various external environmental factors during the deposition process in deep water in the prior art, but currently do not involve the combination of external environmental characteristics with flume experiments, which affects the accuracy and practicality of turbidity current deposition simulation.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

The turbidity flow tube is "Y" shaped, and the "Y" shaped turbidity flow tube has two independent tube bodies, and the first valve is arranged on the independent tube bodies.

[0020] Furthermore, during the rotation adjustment of the first substrate:

[0021] If the first substrate does not completely seal one of the independent tubes during rotation and only opens the independent tube that is not completely sealed, the first substrate forms a partial closure of the turbid flow tube, simulating the turbid flow deposition state of the turbid flow at different flow rates in the deposition chamber.

[0032] When the simulation plate is guided to move counterclockwise, the conductive arc rod controls the sealing block to reset and the sealing block does not pass through the air inlet, and the liquid in the deposition chamber is sucked into the gas gathering arc tube, simulating the turbidity flow deposition state in which the turbidity flow is sucked by the external environment.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0053] The present invention will be further described below in conjunction with the embodiments.

[0054] Example 1 (see Figure 1-4 ): A simulation system for deep-water sedimentary system formation, including at least:

[0055] The main body 100 includes a main body box 110, inside which a side panel 120 in a "U"-shaped structure is installed, and the inside of the side panel 120 is symmetrically slidably connected with a side panel 130, and a rubber sealing strip is integrally formed on the side where the side panel 130 contacts the side panel 120. Thus, a sealed deposition chamber can be formed by the side panel 120 and the two side panels 130, and the spatial size of the deposition chamber can be synchronously adjusted according to the sliding displacement of the side panel 130 in the side panel 120, so as to facilitate the subsequent simulation of deep-water deposition.

[0056] Specifically, a first substrate 140 is rotatably installed inside the side plate 120 and between the symmetrical side plates 130. By stacking and building landform features in the water area on the first substrate 140, such as by stacking semi-solidified coarse sand on the first substrate 140, the landform features of the water area can be formed, and when stacking and building the landform features, the landform features can be stacked into different slope angles, thereby allowing the subsequent simulation of deep-water turbidity current deposition according to the slope surfaces at different angles to analyze the state of turbidity current deposition.

[0057] Further, a second substrate 150 is disposed at one end of the first substrate 140, and the second substrate 150 is fixedly mounted on the side plate 120, and a sealing plate is slidably connected to the inner side of one end of the second substrate 150 close to the side plate 130, and the sealing plate is connected to the inside of the second substrate 150 through a fixed spring, thereby, even when the size of the deposition chamber is adjusted by the side plate 130 in the above, the sealing plate of the second substrate 150 can be stably contacted with the side of the side plate 130, ensuring that the entire deposition chamber will not leak;

[0058] A turbidity flow member 200 is installed above the main body box 110. The turbidity flow member 200 includes a liquid box 210, and the liquid box 210 is provided with two volume chambers B and a volume chamber A. In the present invention, the interior of the volume chamber A is used to store turbidity liquid, and the interior of the volume chamber B is used to store water. The volume chamber A is connected to a turbidity flow pipe 230, and the bottom of the turbidity flow pipe 230 is connected to the side plate 120 and leads to the deposition chamber. A first valve is arranged on the turbidity flow pipe 230, so that the turbidity flow pipe 230 is opened by the first valve to discharge the turbidity liquid into the deposition chamber, and the turbidity liquid is discharged on the first substrate 140. The topographic features are set up to form a deposition simulation of turbidity liquid in deep water. It should be noted that when the turbidity liquid is not introduced, it is necessary to fill the deposition chamber with water in advance (including but not limited to sea water, river water, etc., and it should be noted that the filled water body needs to be combined with the actual water temperature data and salinity data to ensure that the subsequent turbidity deposition simulation can fit the actual water environment) so as to carry out turbidity deposition simulation, thereby testing the flow deposition state of the turbidity liquid in the water body, and recording the deposition state of the turbidity liquid at different times to clarify the deposition performance of the turbidity liquid.

[0059] When constructing the geomorphic features, the upstream slope gradient of the entire geomorphic feature can be set to 6-7°, and the downstream basin bottom gradient can be set to 0-2°, so as to accurately simulate the sedimentation state of the deep-water turbidity current. The upstream slope gradient and the downstream basin bottom gradient can be adjusted according to the actual experimental needs, and are not limited here.

[0060] Furthermore, in this solution, the first substrate 140 is driven by a first motor installed on the side (outer side) of the side plate 120. Thus, when the preset landform feature cannot change the angle of its slope, the first motor can be used to control the first substrate 140 to rotate, so that one end of the first substrate 140 is tilted, thereby achieving the change of the slope angle of the landform feature and solving the problem of the invariance of the frequently constructed landform feature.

[0061] Among them, because the second substrate 150 is not fixedly connected to the first substrate 140 , the second substrate 150 is horizontal, and the first substrate 140 and the second substrate 150 are connected and sealed to prevent water from leaking through the gap between the first substrate 140 and the second substrate 150 .

[0062] It is worth noting that by placing the first substrate 140 at different angles, the landform features can be placed at different slope angles, so as to realize a simulation test of deep-water sedimentation in combination with turbidity currents.

[0063] Furthermore, a slideway 111 is provided on the inner wall of the main box 110, and a slider 131 slidably connected to the slideway 111 is provided at the bottom of the side plate 130. The slideway 111 and the main box 110 are connected by a limiting spring 162, and a limiting rod 161 is sleeved inside the limiting spring 162. The two ends of the limiting rod 161 are respectively installed on the slider 131 and the main box 110, so that the elastic pressure of the limiting spring 162 forces the side plate 130 to contact the first substrate 140, and a deposition chamber is formed at this time. When the first substrate 140 is tilted and rotated in the above-mentioned manner, the side plate 130 is subjected to the elastic pressure of the limiting spring 162 to make the side plate 130 move in the same direction as the first substrate 140, that is, the first substrate 140 moves clockwise, and the side plate 130 in contact with the first substrate 140 moves inward, otherwise, it moves outward, thereby ensuring that a deposition chamber is formed for deposition simulation.

[0064] Among them, the turbidity flow tube 230 is in a "Y" shape. Because the "Y"-shaped turbidity flow tube 230 has two independent tube bodies, and the two independent tube bodies are at different connection positions on the side plate 120, and the outlets of the tube bodies are both connected to the deposition chamber, and the independent tube bodies are each equipped with a first valve. When the first substrate 140 is rotated and adjusted to make the deposition chamber leave one of the turbidity flow tubes 230, the first valve of the other turbidity flow tube 230 can be opened to allow turbidity to be passed in for experiments.

[0065] In this embodiment, as the first substrate 140 tilts and rotates, if the first substrate 140 does not completely seal one of the turbidity flow tubes 230 (independent tube bodies) during the rotation process, and only the turbidity flow tube 230 that is currently not completely sealed is opened, the first substrate 140 forms a partial closure of the turbidity flow tube 230, and instantly simulates the turbidity flow deposition state of the turbidity flow liquid in the deposition chamber at different flow rates, and records the deposition data of the turbidity flow deposition state, so as to clarify the specific state of the turbidity flow deposition in this case, so as to judge the deposition state of the turbidity flow liquid in the water area when the flow rate of the turbidity flow liquid is affected in the current water area.

[0066] A possible implementation method different from the above is as follows: when the first substrate 140 is tilted and rotated, it affects the size of the deposition chamber, and thus the liquid level of the water initially filled in the deposition chamber, i.e., the water level line, will change accordingly to form a turbidity current deposition simulation in accordance with the topographic features of different slope angles and the water level lines of different heights.

[0067] In order to effectively simulate deep-water deposition, the present invention introduces environmental characteristics to simulate deposition, specifically:

[0068] A plurality of nozzles 240 are installed on the upper side of the inner wall of the main box 110, and a cavity is arranged inside the upper side of the inner wall of the main box 110 for storing liquid, the nozzle 240 is connected with the cavity, and the volume chamber B and the cavity are connected through a drain pipe 220, and a second valve is arranged on the drain pipe 220 (in the present invention, the valves on different components are independent, and a valve capable of blocking the fluid can be used). Since the nozzle 240 is located directly above the sedimentation chamber, when the turbidity flow pipe 230 is passed into the turbidity flow, the second valve is opened, so that water can drip on the surface of the water body in the sedimentation chamber in the form of droplets through the nozzle 240, thereby simulating the turbidity flow being deposited in the water area on rainy days, and the surface of the water area fluctuates due to the influence of raindrops, so as to affect the flow of the turbidity flow liquid, which is convenient for analyzing the deposition performance of the turbidity flow liquid in this case.

[0069] The second motors are symmetrically fixedly installed on the side of the main box 110, and the output shaft of each second motor is fixedly connected with a guide simulation plate 300, and one end of the guide simulation plate 300 is rotatably installed on the main box 110. Initially, the guide simulation plate 300 is blocked at the bottom of the nozzle 240 in a horizontal state to seal the nozzle 240, wherein:

[0070] The second motor controls the guide simulation plate 300 to tilt downward and rotate, so that the guide simulation plate 300 does not block the nozzle 240. If the guide simulation plate 300 is tilted, the droplets discharged from some nozzles 240 will drip on the inclined surface of the guide simulation plate 300, and some nozzles 240 close to the middle of the sedimentation chamber will drip onto the surface of the water in the sedimentation chamber as droplets. At this time, through the guidance of the inclined surface of the guide simulation plate 300, the water surface near the two sides of the sedimentation chamber will be simulated to have a greater collision with the water flow guided by the guide simulation plate 300, and the water surface in the middle of the sedimentation chamber will not be affected or will be less affected, thereby simulating the deposition state of turbidity liquid when the deep water surface is affected by different degrees of water vibration and collision.

[0071] A possible implementation method different from the above: during the process of guiding the simulation plate 300 to be tilted and adjusted, if the first substrate 140 is synchronously tilted and adjusted, and the topographic features on the first substrate 140 are squeezed by the guiding simulation plate 300, it is possible to simulate the topographic features being affected by the collision of objects such as hard rocks, and at the same time simulate the turbidity current deposition state of the topographic features in the process of collapse (such as the geology being affected by harsh environment and causing vibrations, collapse, etc., or the vibrations caused by blasting operations in the water area leading to collapse), thereby realizing the analysis of the turbidity current deposition being affected by various influences.

[0072] It should be noted that in this scheme, the turbidity fluid used has different sediment concentrations, such as:

[0073] Low-density turbidity currents, whose sediment concentration is 5%;

[0074] Medium-density turbidity currents, whose sediment concentration is 5-10%;

[0075] High-density turbidity currents, whose sediment concentration is 10%;

[0076] The components of the sediments in the turbidity fluid include kaolin, quartz sand, quartz sand, and quartz sand, etc. At the same time, colored sand can be mixed into the turbidity fluid or dyed with dyes, so that the stratification in the sediments can be better observed and the sedimentation state of the turbidity fluid can be clarified.

[0077] A possible implementation method different from the above is as follows: when the first substrate 140 rotates clockwise to adjust the slope angle of the geomorphic feature, the side plate 130 slides inward (toward the inside of the deposition chamber). If the guide simulation plate 300 is synchronously tilted and rotated downward for adjustment, the guide simulation plate 300 will increase the pressure on the geomorphic feature on the first substrate 140 to simulate the geomorphic feature being subjected to different pressures, such as the influence of hard rock on turbidity current deposition.

[0078] Taking into account the stability of the movement of the guiding simulation board 300 and the comprehensiveness of the deep-water sedimentation simulation, the present invention also includes:

[0079] A compensation simulation member 400 is arranged inside the main box 110, and the compensation simulation member 400 includes a conductive arc rod 410 installed at the bottom of the guide simulation plate 300, and the conductive arc rod 410 is centered on the movable connection point between the guide simulation plate 300 and the main box 110, one end of the conductive arc rod 410 is slidably connected to a gas gathering arc tube 420, the gas gathering arc tube 420 is fixed on the main box 110, and a sealing block is arranged at one end of the conductive arc rod 410 that slides in the gas gathering arc tube 420, and one end of the gas gathering arc tube 420 is connected to a guide simulation tube 430, and the guide simulation tube 430 is installed on the side plate 130 and communicates with the deposition chamber , and the guide simulation tube 430 is a bellows, so that the conductive arc rod 410 follows the movement of the guide simulation plate 300 and slides in the gas gathering arc tube 420, and an air inlet 421 is opened on one end surface of the gas gathering arc tube 420 for air intake (initially, the sealing block is close to the port position of the gas gathering arc tube 420, and the gas enters the gas gathering arc tube 420 through the air inlet 421), that is, the sealing block of the conductive arc rod 410 will squeeze the gas into the water body in the deposition chamber, thereby simulating the deposition state of the turbidity current in the deep water under the influence of the gas in the water body (in this process, the guide simulation plate 300 moves clockwise, that is, the conductive arc rod 410 moves clockwise);

[0080] Here, the conductive arc rod 410 is slidably connected to the gas gathering arc tube 420 to reduce the vibration of the guide simulation plate 300 when it is hit by liquid, that is, the guide simulation plate 300 is more stable to facilitate turbidity flow deposition simulation.

[0081] A possible implementation method different from the above is as follows: after the sealing pressure block of the conductive arc rod 410 compresses the gas into the deposition chamber, the sealing pressure block is close to the inner end of the gas gathering arc tube 420, that is, when the guiding simulation plate 300 is reset, the conductive arc rod 410 controls the sealing pressure block to reset and when the sealing pressure block has not passed through the air inlet 421, the inside of the gas gathering arc tube 420 and the guide simulation tube 430 are in a negative pressure state, and the liquid in the deposition chamber is sucked into the gas gathering arc tube 420. At this time, the turbidity current is simulated when it is sucked by the external environment, and its turbidity current deposition state is simulated. This situation is usually caused by water workers sucking liquid in the water area through equipment, so as to conduct a practical turbidity current deposition analysis (in this process, the guiding simulation plate 300 moves counterclockwise, that is, the conductive arc rod 410 moves counterclockwise).

[0082] It is worth mentioning that the end of the guide simulation tube 430 is installed on the side plate 130 and is connected to the deposition chamber. Therefore, the installation position of the guide simulation tube 430 on the side plate 130 can be set according to the slope angle reached by the rotation of the first substrate 140 following the terrain characteristics to avoid the guide simulation tube 430 being sealed by the tilted rotation of the first substrate 140.

[0083] Finally, the gas gathering arc tube 420 is fixedly installed on the main box 110, and the air inlet 421 is exposed, so a receiving ring 440 is sleeved on the side of the main box 110 and located on the outer side of the air inlet 421 to receive the liquid when it flows out through the air inlet 421.

[0084] In the above, after the turbidity current deposition simulation is completed, water is pumped out with a water pump, and it is ensured that the sediment will not collapse due to the pumping. After it is completely drained, the sediment morphology is observed, and the landform feature data is scanned with a laser scanner to obtain the landform feature morphology before and after deposition, the sediment deposition rate, sediment layer thickness and sediment structure digital parameters of the sediment, so as to form an analysis and monitoring of turbidity current deposition.

[0085] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
