Description

Technical Field

[0001] The invention relates to the technical field of dredging simulation, and in particular to a device and method for simulating dredging area leveling. Background Art

[0002] Most of the current large dredgers are suction dredgers, which use the high-pressure water gun and suction device of the dredger head to transport seabed mud to the mud tank of the dredger through the mud pipe. After the dredger dredges the terrain, the underwater terrain is not flat, and there are often raised ridges or over-dug waters. For raised ridges, secondary excavation or raking with a rake is often required to meet the designed bottom elevation of the waterway. Whether the dredger uses secondary excavation or rakes needs to be judged by some technical indicators. These technical indicators are calculated based on the terrain distribution law of the dredged dredger. It is difficult to obtain these technical indicator data in actual operations, and there is a lack of experimental theoretical research on the state distribution of the terrain after dredging by the dredger.

[0003] In the prior art, the invention patent with patent application number CN202410750822.5 discloses a device, system and method for simulating dredging of silt by a dredger, which utilizes a dredging mechanism to dredge the silt, drives the movement of the dredging mechanism through a moving mechanism, simulates the dredging process of a suction dredger, and collects terrain data after simulated dredging by a measuring mechanism to provide data support for experimental theoretical research, and calculates indicators such as the mean square error and deviation of the dredged terrain according to the terrain distribution law; however, it cannot accurately and intuitively observe the state distribution of the terrain after dredging, for raised ridges, secondary excavations or raking by a rake, by only using the calculation method; and in the specific operation process, after each dredging of the silt, it is necessary to wait for the silt in the water body to sink before observing it or measuring the terrain elevation, which results in a long waiting time and reduces work efficiency.

[0018] The present invention also discloses a method for simulating dredging area leveling, which is performed by applying the aforementioned device for simulating dredging area leveling, and includes the following steps:

[0019] S1: According to the experimental requirements, a certain volume of sediment is added into the transparent box;

[0020] S2: Control the lifting and transverse movement and scraping mechanism to work, so that the motor in one of the first sleeves drives the reciprocating screw to rotate, the second sleeve moves along the axial direction of the reciprocating screw, and the second sleeve drives the push seat to move transversely, so that the push seat moves from one end of the transparent box to the other end;

[0021] At the beginning of the movement of the push seat, the push seat abuts against the first scraper, and the first scraper moves under force, and the first scraper pushes the mud and sand piled in the transparent box to the other side. When the first scraper moves to the second scraper at the other end, the horizontal plate on the top of the first scraper abuts against the horizontal plate on the top of the second scraper, and the first scraper cannot continue to move horizontally, and the excess mud and sand is piled between the two vertical plates;

[0022] As the second sleeve drives the push seat to continue to move, the extrusion inclined surface of the push seat is stressed, and the push seat moves up relative to the first scraper until the push seat passes over the auxiliary inclined surface and moves to the upper side of the second scraper. At this time, the first scraper is reset and moved back under the pull of the first elastic telescopic rod connected to it. As the second sleeve drives the push seat to continue to move, the push seat finally passes over the second scraper. At this time, the extrusion inclined surface of the push seat is no longer stressed, and the push seat is reset and moved downward under the elastic pull of the second elastic telescopic rod.

[0023] When the second sleeve drives the push seat to move toward the end of the reciprocating screw rod, the rack plate on the second sleeve meshes with the driven gear on the first screw rod, the driven gear drives the first screw rod to rotate, and the first sleeve drives the lateral movement assembly to move upward, thereby raising the height of the first scraper and the second scraper;

[0024] S3: Continue to control the reciprocating screw to rotate continuously, and the second sleeve automatically moves back after moving to the end of the reciprocating screw. At this time, the push seat on the second sleeve starts to push the second scraper to move. When the second sleeve drives the rack plate to move back, it meshes with the driven gear and cannot drive the first screw that has been rotating to rotate again, repeating the previous scraping work of the first scraper on the mud and sand, so that the excess mud and sand between the two vertical plates are scraped, and the cycle is repeated, so that the first scraper and the second scraper cooperate, and the horizontal movement action and the lifting action work alternately until all the mud and sand in the transparent box are finally scraped flat;

[0025] S4: Then the first electric push rod is controlled to drive the rake head to move downward, so that the rake head penetrates into the flattened mud and sand, and the moving mechanism drives the rake head to move, simulating the dredging process. After the rake head moves, raised ridges appear in the mud and sand in the transparent box, and the rangefinder measures the dredged terrain in real time;

[0026] S5: Then the rake head is driven upward by the first electric push rod, so that the moving mechanism drives the mounting seat to move to the initial position, and the staff controls the rake head and the rake leveler to move downward respectively, so that the rake head and the rake leveler respectively perform secondary excavation and rake leveling operations on the dredged mud and sand terrain, and the distance meter measures the distance of the mud and sand terrain after rake leveling and the mud and sand terrain after the secondary excavation by the rake head, and the staff members visually observe the difference between the two dredging methods;

[0027] S6: After the first sleeve is moved downward along the first screw axis through the driving unit, the first scraper and the second scraper go deep into the mud again. The staff repeats S2-S5 to control the lifting and transverse scraping mechanism to scrape the dredged mud in the transparent box again, so that the scraper head goes deep into the scraped mud to perform dredging work at different depths each time. The difference in terrain distribution between the secondary excavation of the scraper head and the terrain after the scraper is leveled is visually observed at different dredging depths.

[0028] Compared with the prior art, the present invention provides a device and method for simulating dredging area leveling, which has the following beneficial effects:

[0029] 1. The device and method for simulating the leveling of the dredged area. After dredging the sediment, the rake head uses the rake leveler to rake and level the dredged terrain, and the rake head performs secondary excavation on the dredged terrain, which is convenient for the staff to visually observe the distribution of the terrain status after dredging, and provide data support for experimental theoretical research. Through laboratory simulation, the terrain distribution rate after dredging by the dredging ship is studied, the terrain distribution after dredging is verified, and then the operation mode of the dredging ship on-site construction is proposed to improve the dredging operation efficiency of the dredger.

[0030] 2. The device and method for simulating the leveling of the dredged area, because the silt caused by the secondary excavation of the rake head and the rake leveler will cause turbidity in the water body, only silt is placed in a transparent box to simulate the underwater topography of the dredged river, and the interference conditions of silt turbidity in the water body are removed, avoiding the situation that the turbidity of the water body caused by the rake head dredging requires a long time to stand still for observation and distance measurement, thereby ensuring the efficiency and simulation effect of silt dredging simulation.

[0031] 3. The device and method for simulating the leveling of the dredged area can re-level the dredged sediment terrain after each test by setting a lifting and transversely moving scraping mechanism. The leveling of the sediment in the transparent box can be achieved through only one driving device. The operation is simple, and the sediment leveling errors and time-consuming problems caused by manual operation are reduced, which is convenient for improving the efficiency and effect of sediment dredging simulation.

DETAILED DESCRIPTION

[0044] 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.

[0045] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] Example 1: Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , a device for simulating the leveling of a dredging area, comprising a transparent box 1 with mud and sand laid on the bottom, and also comprising:

[0047] A moving mechanism, the moving mechanism is connected to a mounting seat 2, the mounting seat 2 is provided with two first electric push rods 201, and the ends of the two first electric push rods 201 are respectively provided with a rake 202 and a rake head 203; and

[0048] The lifting and transversely moving scraping mechanism includes a first scraper 3 and a second scraper 301 arranged on both sides of the transparent box 1, a transverse moving component for driving the first scraper 3 and the second scraper 301 to move transversely, and a lifting component for driving the first scraper 3 and the second scraper 301 to lift and lower;

[0049] The transverse moving assembly is arranged on the lifting assembly, and the first scraper 3 and the second scraper 301 are connected to the lifting assembly.

[0050] Specifically, according to the experimental requirements, a certain volume of sediment is put into the transparent box 1, and the lifting and transverse movement scraping mechanism is controlled to work, so that the first scraper 3 and the second scraper 301 cooperate to evenly flatten all the sediment in the transparent box 1, and then the first electric push rod 201 is controlled to operate, so that the first electric push rod 201 drives the rake head 203 to penetrate into the sediment, and the moving mechanism drives the rake head 203 to move, so as to realize the simulation of dredging the sediment, and then the rake head 203 is moved out of the sediment, and the moving mechanism drives the mounting seat 2 to reset, and the staff respectively operate on the dredged sediment terrain through the rake leveler 202 and the rake head 203, so that the staff can analyze the distribution of the terrain state after dredging. Conduct intuitive observation to provide data support for experimental theoretical research. Through laboratory simulation, study the terrain distribution rate after dredging by the dredging ship, verify the terrain distribution after dredging, and then propose the operation mode of on-site construction of the dredging ship to improve the dredging operation efficiency of the dredger. Moreover, due to the secondary excavation of the rake head 203 and the silt caused by the rake leveler 202, turbidity will appear in the water body. By placing only silt in the transparent box 1 to simulate the underwater terrain of the dredged river, the interference conditions of silt turbidity in the water body are removed, and the turbidity of the water body caused by the dredging of the rake head 203 needs to be left still for a long time before observation and ranging is avoided, thereby ensuring the simulation efficiency and simulation effect of silt dredging.

[0051] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 , a device for simulating leveling of a dredging area, based on Example 1, further, two groups of lifting components are provided and are symmetrically arranged along the width direction of the transparent box 1, each group of lifting components includes support plates 4 fixedly arranged at both ends of the transparent box 1, each support plate 4 is rotatably connected to a first screw 401, and the first screws 401 at both ends of each group of lifting components are provided with synchronous wheels 402, and a synchronous belt is provided between the two synchronous wheels 402, and the first screws 401 at both ends of each group of lifting components are threadedly connected to first sleeves 403, each first sleeve 403 is connected to a connecting rod 404, and the connecting rods 404 at both ends of each group of lifting components are connected to the first scraper 3 or the second scraper 301 on the same side. It should be noted that the connecting rods 404 at both ends of each group of lifting components are connected to the scraper on the same side, that is, the connecting rod 404 at one end is connected to the first scraper 3, and the connecting rod 404 at the other end is connected to the second scraper 301.

[0052] Furthermore, a driving part 405 for driving the first screw rod 401 to rotate is fixedly provided on one of the support plates 4, and the driving part 405 is driven by a motor or a hand crank.

[0053] Specifically, the staff can control the action of the driving part 405. The driving part 405 can use a motor or a hand crank to drive the first screw 401 to rotate. When one first screw 401 rotates, it drives the other first screw 401 to rotate through the synchronous wheel 402 and the synchronous belt. When the first screw 401 rotates, the first sleeve 403 moves axially along the first screw 401, so that the two first sleeves 403 respectively drive the first scraper 3 and the second scraper 301 to rise or fall through the connecting rod 404.

[0054] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 , a device for simulating leveling of a dredging area. On the basis of Example 2, further, an L-shaped plate 5 is fixedly provided on the outer side of the transparent box 1, a first elastic telescopic rod 501 is fixedly provided on the L-shaped plate 5, a slider 502 is fixedly provided on the end of the first elastic telescopic rod 501 away from the L-shaped plate 5, and a sliding groove 503 for sliding of the slider 502 is opened on the first scraper 3 and the second scraper 301.

[0055] Furthermore, the transverse movement assembly includes a reciprocating screw 6 rotatably connected between two first sleeves 403 of each group of lifting assemblies, wherein a motor for driving the reciprocating screw 6 to rotate is arranged in one of the first sleeves 403, a second sleeve 601 is threadedly connected to the reciprocating screw 6, a side plate 602 is fixedly provided on the second sleeve 601, a second elastic telescopic rod 603 is fixedly provided on the side plate 602, the second elastic telescopic rod 603 is connected to a push seat 604, and the push seat 604 is movably opposed to the first scraper 3 and the second scraper 301.

[0056] Furthermore, the first scraper 3 and the second scraper 301 have the same structure, both including a vertical plate 3011 and a horizontal plate 3012 perpendicularly arranged to the vertical plate 3011 , the push seat 604 is provided with an extrusion slope that is movably opposed to the first scraper 3 and the second scraper 301 , and the horizontal plate 3012 is provided with an auxiliary slope.

[0057] Furthermore, a rack plate 7 is fixedly provided on the second sleeve 601 , and a driven gear 8 meshing with the rack plate 7 is rotatably connected to the first sleeve 403 . The driven gear 8 is slidably arranged with the first screw rod 401 , and the driven gear 8 is arranged as a one-way gear.

[0058] Furthermore, a guide bar 801 is fixedly disposed on the inner side wall of the driven gear 8 , and a guide groove 4011 for the guide bar 801 to slide is formed along the axial direction of the first screw rod 401 .

[0059] Specifically, when the lifting and lateral movement and scraping mechanism is controlled to work, the motor in one of the first sleeves 403 drives the reciprocating screw 6 to rotate, the second sleeve 601 moves along the axial direction of the reciprocating screw 6, and the second sleeve 601 drives the push seat 604 to move horizontally, so that the push seat 604 moves from one end of the transparent box 1 to the other end;

[0060] At the beginning of the movement of the push seat 604, the push seat 604 abuts against the first scraper 3, and the first scraper 3 moves under the force, and the first scraper 3 pushes the mud and sand piled in the transparent box 1 to the other side. When the first scraper 3 moves to the second scraper 301 at the other end, the horizontal plate 3012 on the top of the first scraper 3 abuts against the horizontal plate 3012 on the top of the second scraper 301, and the first scraper 3 cannot continue to move horizontally, and the excess mud and sand is piled between the two vertical plates 3011;

[0061] As the second sleeve 601 drives the push seat 604 to continue to move, the extrusion slope of the push seat 604 is stressed, and the push seat 604 moves upward relative to the first scraper 3 until the push seat 604 passes over the auxiliary slope and moves to the upper side of the second scraper 301. At this time, the first scraper 3 is pulled back by the first elastic telescopic rod 501 connected thereto. As the second sleeve 601 drives the push seat 604 to continue to move, the push seat 604 finally passes over the second scraper 301. At this time, the extrusion slope of the push seat 604 is no longer stressed, and the push seat 604 is pulled back by the elastic force of the second elastic telescopic rod 603.

[0062] When the second sleeve 601 drives the push seat 604 to move toward the end of the reciprocating screw rod 6, the rack plate 7 on the second sleeve 601 meshes with the driven gear 8 on the first screw rod 401, and the driven gear 8 drives the first screw rod 401 to rotate, and the first sleeve 403 drives the lateral movement assembly to move upward, thereby raising the height of the first scraper 3 and the second scraper 301;

[0063] Continue to control the reciprocating screw 6 to rotate continuously, and the second sleeve 601 automatically moves back after moving to the end of the reciprocating screw 6. At this time, the push seat 604 on the second sleeve 601 starts to push the second scraper 301 to move. When the second sleeve 601 drives the rack plate 7 to move back, it meshes with the driven gear 8 and cannot drive the first screw 401 that has been rotating before to rotate again (it should be noted that when the driving part 405 drives the first screw 401 to rotate, the first screw 401 drives the driven gear 8 to rotate through the guide bar 801, and the rotation of the driven gear 8 and the rack plate 7 does not drive the rack plate 7 to move). Repeat the previous scraping work of the first scraper 3 on the mud and sand, so that the excess mud and sand between the two vertical plates 3011 is scraped, and the cycle is repeated, so that the first scraper 3 and the second scraper 301 cooperate, and the horizontal movement action and the lifting action work alternately until all the mud and sand in the transparent box 1 are finally scraped flat;

[0064] The present application integrates the lateral scraping action of the first scraper 3 and the second scraper 301 with the lifting action of the first scraper 3 and the second scraper 301, so that the above components act as a linkage mechanism for continuous action and cooperate with each other. Only one driving device is needed to quickly level the mud and sand in the transparent box 1. The operation is simple, and the problems of mud and sand leveling errors and long time consumption caused by manual operation are reduced, so as to improve the efficiency and effect of mud dredging simulation.

[0065] Example 4: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a device for simulating leveling of a dredging area, based on Example 3, further, a moving mechanism includes a fixed plate 9 fixedly mounted on the side of a transparent box 1, a moving motor 901 is fixedly mounted on the fixed plate 9, a second screw 902 connected to the output shaft of the moving motor 901 is rotatably connected to the fixed plate 9, a third sleeve 903 is threadedly connected to the second screw 902, a moving frame 904 is fixedly mounted on the third sleeve 903, a mounting seat 2 is slidably connected to the moving frame 904, a second electric push rod 905 is arranged between the mounting seat 2 and the moving frame 904, a mud pump 10 is arranged on the moving frame 904, the mud pump 10 is connected to the rake head 203 through a mud pumping pipe, and a rangefinder 11 is also arranged at the bottom of the moving frame 904.

[0066] Specifically, when the moving mechanism is working, it controls the moving motor 901 to run, and the output shaft of the moving motor 901 drives the second screw 902 to rotate. When the second screw 902 rotates, the third sleeve 903 moves along its axial direction, so that the third sleeve 903 drives the mounting seat 2 to move through the moving frame 904, and then the mounting seat 2 drives the rake head 203 and the rake leveler 202 to move, thereby realizing the rake leveling and dredging operations of the mud and sand in the transparent box 1.

[0067] The present invention also discloses a method for simulating dredging area leveling, which is performed by applying the aforementioned device for simulating dredging area leveling, and includes the following steps:

[0068] S1: according to the experimental requirements, a certain volume of sediment is put into the transparent box 1;

[0069] S2: Control the lifting and transverse movement and scraping mechanism to work, so that the motor in one of the first sleeves 403 drives the reciprocating screw 6 to rotate, and the second sleeve 601 moves along the axial direction of the reciprocating screw 6, and the second sleeve 601 drives the push seat 604 to move transversely, so that the push seat 604 moves from one end of the transparent box 1 to the other end;

[0070] At the beginning of the movement of the push seat 604, the push seat 604 abuts against the first scraper 3, and the first scraper 3 moves under the force, and the first scraper 3 pushes the mud and sand piled in the transparent box 1 to the other side. When the first scraper 3 moves to the second scraper 301 at the other end, the horizontal plate 3012 on the top of the first scraper 3 abuts against the horizontal plate 3012 on the top of the second scraper 301, and the first scraper 3 cannot continue to move horizontally, and the excess mud and sand is piled between the two vertical plates 3011;

[0071] As the second sleeve 601 drives the push seat 604 to continue to move, the extrusion slope of the push seat 604 is stressed, and the push seat 604 moves upward relative to the first scraper 3 until the push seat 604 passes over the auxiliary slope and moves to the upper side of the second scraper 301. At this time, the first scraper 3 is pulled back by the first elastic telescopic rod 501 connected thereto. As the second sleeve 601 drives the push seat 604 to continue to move, the push seat 604 finally passes over the second scraper 301. At this time, the extrusion slope of the push seat 604 is no longer stressed, and the push seat 604 is pulled back by the elastic force of the second elastic telescopic rod 603.

[0072] When the second sleeve 601 drives the push seat 604 to move toward the end of the reciprocating screw rod 6, the rack plate 7 on the second sleeve 601 meshes with the driven gear 8 on the first screw rod 401, and the driven gear 8 drives the first screw rod 401 to rotate, and the first sleeve 403 drives the lateral movement assembly to move upward, thereby raising the height of the first scraper 3 and the second scraper 301;

[0073] S3: Continue to control the reciprocating screw 6 to rotate continuously, and the second sleeve 601 automatically moves back after moving to the end of the reciprocating screw 6. At this time, the push seat 604 on the second sleeve 601 starts to push the second scraper 301 to move. When the second sleeve 601 drives the rack plate 7 to move back, it meshes with the driven gear 8 and cannot drive the first screw 401 that has been rotating to rotate again, repeating the previous scraping work of the first scraper 3 on the mud and sand, so that the excess mud and sand between the two vertical plates 3011 is scraped, and the cycle is repeated, so that the first scraper 3 and the second scraper 301 cooperate, and the horizontal movement action and the lifting action work alternately until all the mud and sand in the transparent box 1 are finally scraped flat;
