Description

Technical Field

[0001] This invention relates to the field of trailing suction hopper dredger technology, and more particularly to a large-capacity trailing suction hopper dredger for increasing silt loading capacity and its usage method. Background Technology

[0002] The loading process of existing dredgers is divided into a loading stage and an overflow stage. In the loading stage, the dredged mud is pumped into the mud tank via a mud discharge pipe until the mud level reaches the overflow pipe. Then, the overflow stage begins. As the dredged mud continues to be pumped into the mud tank, coarse particles of mud and sand gradually settle inside, while water and low-concentration mud that cannot settle overflow through the overflow pipe, increasing the mud loading capacity. This overflow process increases the concentration of the material in the mud tank to a certain extent; therefore, the overflow method is a commonly used method for increasing the mud concentration in dredging operations.

[0003] However, the overflow method is no longer economically feasible for dredging fine-grained silt. During dredging, the turbulence of the slurry within the silt chamber makes it difficult for the fine particles to settle. As the overflow process continues, the concentration of silt overflowing from the silt chamber through the overflow pipe is almost equal to the concentration of silt pumped into the silt chamber, resulting in a low silt concentration inside the silt chamber. This reduces the amount of silt loaded into the silt chamber, causing a significant waste of manpower, material resources, and financial resources. Simultaneously, the continuous discharge of slurry into the silt chamber impacts the slurry already poured into the chamber, making it difficult for the slurry to effectively settle and stratify, reducing the separation rate of silt from the water, affecting the silt loading efficiency of the silt chamber, and resulting in a large amount of silt in the overflow water, causing secondary pollution to the water body. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a large-capacity trailing suction hopper dredger for increasing the silt loading capacity and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A large-capacity trailing suction hopper dredger for increasing sediment loading capacity includes a hull and further includes: A mud tank, which is fixed to the hull, and a partition plate is fixed inside the mud tank, which divides the mud tank into several sub-compartments. A track frame is installed on the upper side of the mud chamber, and a first support rod is provided between the track frame and the partition plate; A sludge discharge mechanism, mounted on the upper side of the sludge chamber and movable along a track frame, is used to discharge sludge into each compartment. The sludge discharge mechanism includes a sludge discharge pipe and a sludge discharge assembly for driving the displacement of the sludge discharge pipe; and A pumping assembly, which is mounted on the sludge discharge mechanism, is used to extract the supernatant from each compartment.

[0006] Preferably, the partition includes a transverse partition arranged along the length of the mud chamber and a plurality of longitudinal partitions arranged intersecting the transverse partitions, and each of the compartments is formed by the transverse partitions, the longitudinal partitions and the inner wall of the mud chamber.

[0007] Preferably, the track frame includes two annular frames and two connecting frames for connecting the two annular frames, and toothed plates are provided on both the annular frames and the connecting frames.

[0008] Preferably, the sludge discharge assembly includes a movable seat slidably connected to the track frame, a drive motor fixedly mounted on the movable seat, the output shaft of the drive motor passing through the movable seat and connected to a drive gear meshing with a toothed plate, and a connecting plate connected to the sludge discharge pipe fixedly mounted on the outside of the movable seat.

[0009] Preferably, the sludge discharge pipe includes a sludge discharge pipe fixedly connected to a connecting plate, a first telescopic pipe connected to the sludge discharge pipe, a bent pipe connected to the end of the first telescopic pipe away from the sludge discharge pipe, and a sludge extraction pipe rotatably connected to the bent pipe. The sludge extraction pipe is connected to the hull via a bracket.

[0010] Preferably, a rotating rod is rotatably connected inside the mud discharge pipe, and a plurality of paddles are evenly arranged circumferentially on the rotating rod. A storage shell is provided on the outside of the mud discharge pipe, and a baffle is slidably connected to the bottom of the storage shell. An elastic telescopic rod is fixed between the inner wall of the storage shell and the baffle. A discharge hole is provided on both the bottom of the storage shell and the baffle. A movable gear is rotatably connected inside the storage shell. The end of the rotating rod away from the mud discharge pipe passes through the storage shell and is connected to an incomplete gear that intermittently meshes with the movable gear. A drum is provided on the movable gear, and a pull rope connected to the baffle is wound around the drum.

[0011] Preferably, the pumping assembly includes a support plate mounted on a movable seat, a water pump fixed on the support plate, a pumping end connected to a pumping pipe, a pumping hose connected to the end of the pumping pipe away from the water pump, a pumping hose placed in the compartment body at the end of the pumping hose away from the pumping pipe, a drain pipe connected to the outlet end of the water pump, and a drainage channel cooperating with the drain pipe provided between the hull and the mud tank.

[0012] Preferably, a hydraulic cylinder is fixedly mounted on the support plate, the piston rod of the hydraulic cylinder is connected to a lifting plate, and a second telescopic pipe for connecting the water pumping pipe and the water pumping hose is fixedly mounted on the lifting plate.

[0013] Preferably, a second support rod is fixedly provided on the partition plate, and an auxiliary frame with the same shape as the track frame is fixedly provided at the end of the second support rod away from the partition plate. The auxiliary frame has a movable groove, and a slider that is slidably connected to the support plate is movably connected in the movable groove. The end of the support plate away from the slider is rotatably connected to the movable seat.

[0014] This invention also discloses a method for using a large-capacity trailing suction hopper dredger to increase sediment loading capacity, comprising the following steps: S1: When the trailing suction hopper is working, the lower mud pipe of the mud discharge pipe is located on the upper side of the compartment in the initial position. The mud is extracted by the mud suction pipe of the mud discharge pipe, and then the mud discharge pipe discharges the extracted mud into the mud compartment. S2: Control the operation of the drive motor. The output shaft of the drive motor drives the drive gear to mesh with the toothed plate on the track frame, so that the moving seat moves along the track frame. As the moving seat moves, the mud discharge pipe continuously discharges the mud into each compartment in sequence. S3: The mud discharged into the compartment is not impacted by the mud in other compartments, allowing the mud entering the compartment sufficient time to settle and separate into layers, effectively separating the mud and water until the mud discharge pipe moves back to the upper side of the compartment. S4: After the sludge discharge pipe moves one revolution with the track frame, each compartment in the sludge chamber is filled with sludge. When the sludge discharge pipe is about to discharge sludge to the compartment at the initial position again, the water pump connected to the pump on the outer support plate of the moving seat enters the compartment at the initial position first to extract the supernatant in the compartment at the initial position. The extracted supernatant is discharged to the drain tank through the drain pipe. S5: As the drive motor continues to run, the mud pipe moves back to the upper side of the compartment at the initial position, and discharges mud again into the compartment after the supernatant has been extracted, allowing the mud and sand to settle and separate. Meanwhile, the water pumping hose enters the next compartment to extract and discharge the supernatant that has been settled and separated, leaving enough loading space for the subsequent mud discharge pipe to continue discharging mud, until all compartments in the mud chamber are filled with mud and sand.

[0015] Compared with the prior art, the present invention provides a large-capacity trailing suction hopper dredger for increasing sediment loading capacity and its method of use, which has the following beneficial effects: 1. The large-capacity trailing suction hopper dredger and its usage method for increasing silt loading capacity divide the silt hopper into several compartments through partition plates. The silt discharged into the compartments is not impacted by the silt in other compartments, allowing sufficient time for the silt to settle and separate into layers, effectively separating the silt and water. Before the silt discharge pipe discharges silt into the compartments again, the pumping unit extracts the supernatant that has completed the separation, leaving sufficient loading space for the subsequent silt discharge pipe to continue discharging silt, thereby increasing the silt loading capacity and loading efficiency of the silt hopper.

[0016] 2. The large-capacity trailing suction hopper vessel for increasing silt loading capacity and its usage method, by setting the silt discharge pipe as a connected silt discharge pipe, a first telescopic pipe, a bending pipe and a silt extraction pipe, and making the silt extraction pipe and the bending pipe rotatably connected, so that when the silt discharge pipe moves along the track frame with the moving seat, the first telescopic pipe automatically extends and retracts, and the bending pipe rotates relative to the silt extraction pipe, thus avoiding the need for the silt discharge pipe to wind a long distance when it moves with the moving seat, resulting in an excessively long slurry transportation distance and affecting the slurry discharge speed, thereby ensuring the silt loading efficiency of the silt tank.

[0017] 3. The large-capacity trailing suction hopper dredger and its operating method for improving silt loading capacity apply thrust to the deflector when slurry is discharged through the silt discharge pipe. This causes the deflector to drive the rotating rod to rotate. When the rotating rod rotates, it causes the incomplete gear and the movable gear to mesh intermittently. This causes the movable gear to intermittently wind the pull rope through the drum, causing the baffle to move back and forth in conjunction with the elastic telescopic rod. When the baffle moves back and forth, the discharge hole on it coincides with the discharge hole at the bottom of the storage tank, so that the flocculant in the storage tank can fall automatically. This allows the flocculant to mix with the slurry discharged into the compartment, accelerating the rapid settling of silt in the compartment, thereby improving the silt loading efficiency and loading effect of the silt tank.

[0018] 4. The large-capacity trailing suction hopper dredger used to increase silt loading capacity and its operating method: As silt is discharged into each compartment through the silt discharge pipe, the silt accumulation in the compartment increases, and the liquid level of the supernatant rises. By setting up a hydraulic cylinder to push the lifting plate upward, the lifting plate drives the pumping hose upward through the second telescopic pipe, so that the height of the pumping hose for each extraction of supernatant from the compartment is raised, avoiding the pumping hose from extracting the deposited silt and ensuring the effective discharge of excess water in the silt compartment.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 This embodiment proposes a large-capacity trailing suction hopper dredger for increasing sediment loading capacity, including a hull 1, and further comprising: Mud compartment 2 is fixedly installed on the hull 1. A partition plate 3 is fixedly installed inside the mud compartment 2, which divides the mud compartment 2 into several sub-compartments. Track frame 4 is installed on the upper side of mud chamber 2, and a first support rod 5 is installed between track frame 4 and partition plate 3; A sludge discharge mechanism, located on the upper side of the sludge chamber 2 and movable along the track frame 4, is used to discharge sludge into each compartment. The sludge discharge mechanism includes a sludge discharge pipe 6 and sludge discharge components for driving the displacement of the sludge discharge pipe 6; and The pumping assembly is installed on the sludge discharge mechanism and is used to extract the supernatant from each compartment.

[0025] Furthermore, the partition 3 includes a transverse partition 301 arranged along the length of the mud chamber 2 and a number of longitudinal partitions 302 arranged intersecting with the transverse partition 301. Each compartment is formed by the transverse partition 301, the longitudinal partitions 302 and the inner wall of the mud chamber 2.

[0026] Specifically, when the trailing suction hopper is working, the end of the sludge discharge pipe 6 is located on the upper side of the compartment in the initial position. The front end of the sludge discharge pipe 6, in conjunction with the rake head, extracts sludge. Then, the sludge discharge pipe 6 discharges the extracted sludge into the mud chamber 2. The mud chamber 2 is divided into several compartments by the partition plate 3. The sludge discharged into the compartments is not impacted by the sludge in other compartments, allowing the sludge entering the compartments sufficient time to settle and separate into layers, effectively separating the sludge and water. After the sludge discharge pipe 6 moves one revolution with the track frame 4, each compartment in the mud chamber 2 is filled with sludge. Before the sludge discharge pipe 6 discharges sludge into the compartments again, the pumping unit extracts the supernatant that has completed the separation work, leaving sufficient loading space for the sludge discharge pipe 6 to continue discharging sludge, thereby improving the sludge loading capacity and loading efficiency of the mud chamber 2.

[0027] Reference Figure 1 , Figure 2, Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 10 As a preferred embodiment, based on the above method, the track frame 4 further includes two ring frames 401 and two connecting frames 402 for connecting the two ring frames 401. Both the ring frames 401 and the connecting frames 402 are provided with toothed plates 403.

[0028] Furthermore, the sludge discharge assembly includes a movable seat 7 slidably connected to the track frame 4, a drive motor 701 fixedly mounted on the movable seat 7, the output shaft of the drive motor 701 passing through the movable seat 7 and connected to a drive gear 702 meshing with the toothed plate 403, and a connecting plate 703 connected to the sludge discharge pipe 6 fixedly mounted on the outside of the movable seat 7.

[0029] Furthermore, the sludge discharge pipe 6 includes a sludge discharge pipe 601 fixedly connected to the connecting plate 703, a first telescopic pipe 602 connected to the sludge discharge pipe 601, a bent pipe 603 connected to the end of the first telescopic pipe 602 away from the sludge discharge pipe 601, and a sludge extraction pipe 604 rotatably connected to the bent pipe 603. The sludge extraction pipe 604 is connected to the hull 1 through a bracket.

[0030] Specifically, when the trailing suction hopper is working, the lower mud pipe 601 of the mud discharge pipe 6 is located on the upper side of the compartment in the initial position. The mud is extracted by the mud suction pipe 604 of the mud discharge pipe 6. Then, the mud discharge pipe 6 discharges the extracted mud into the mud compartment 2. The drive motor 701 is controlled to run. The output shaft of the drive motor 701 drives the drive gear 702 to mesh with the toothed plate 403 on the track frame 4, so that the moving seat 7 moves along the track frame 4. As the moving seat 7 moves, the mud discharge pipe 6 continuously discharges the mud into each compartment in sequence. The mud discharged into the compartment is not impacted by the mud in other compartments, so that the mud entering the compartment has enough time to settle and separate into layers, so that the mud and water are effectively separated. By configuring the sludge discharge pipe 6 as a connected sludge lowering pipe 601, a first telescopic pipe 602, a bending pipe 603, and a sludge extraction pipe 604, and by rotatably connecting the sludge extraction pipe 604 and the bending pipe 603, the first telescopic pipe 602 automatically extends and retracts when the sludge lowering pipe 601 moves along the track frame 4 with the moving seat 7, and the bending pipe 603 rotates relative to the sludge extraction pipe 604. This avoids the sludge discharge pipe 6 having to wind around a long distance when it moves with the moving seat 7, which would result in an excessively long sludge transport distance and affect the sludge discharge speed, thereby ensuring the loading efficiency of the mud chamber 2.

[0031] Reference Figure 1 , Figure 3 and Figure 11As a preferred embodiment, based on the above method, a rotating rod 13 is rotatably connected inside the mud-drain pipe 601. Several paddles 131 are evenly arranged in a circle on the rotating rod 13. A storage shell 14 is provided on the outside of the mud-drain pipe 601. A baffle 141 is slidably connected to the bottom of the storage shell 14. An elastic telescopic rod 144 is fixed between the inner wall of the storage shell 14 and the baffle 141. A discharge hole 142 is opened on the bottom of the storage shell 14 and the baffle 141. A movable gear 143 is rotatably connected inside the storage shell 14. The end of the rotating rod 13 away from the mud-drain pipe 601 passes through the storage shell 14 and is connected to an incomplete gear 145 that intermittently meshes with the movable gear 143. A drum 146 is provided on the movable gear 143. A pull rope 147 connected to the baffle 141 is wound around the drum 146.

[0032] Specifically, when the mud in the mud discharge pipe 601 is discharged, a pushing force is applied to the lever 131, causing the lever 131 to drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it drives the incomplete gear 145 to intermittently mesh with the movable gear 143, which in turn causes the movable gear 143 to intermittently wind the pull rope 147 through the drum 146, causing the baffle 141 to move back and forth in conjunction with the elastic telescopic rod 144. When the baffle 141 moves back and forth, the discharge hole 142 on it and the bottom of the storage shell 14 are engaged with each other. The discharge holes 142 overlap, enabling the flocculant in the storage shell 14 to fall automatically, allowing the flocculant to mix with the mud discharged into the compartment, accelerating the rapid settling and separation of mud and sand in the compartment, thereby improving the mud loading efficiency and loading effect of the mud compartment 2; it should be noted that the mud discharge pipe 601 should be equipped with a guide block or guide plate to guide the mud, so that the mud drives the paddle 131 at the same position to rotate, so that the rotating rod 13 rotates continuously in one direction, which is common knowledge to those skilled in the art.

[0033] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As a preferred embodiment, based on the above method, the pumping assembly further includes a support plate 8 mounted on the movable seat 7, a water pump 801 fixed on the support plate 8, a pumping end of the water pump 801 connected to a pumping pipe 802, a pumping hose 803 connected to the end of the pumping pipe 802 away from the water pump 801, the end of the pumping hose 803 away from the pumping pipe 802 placed in the compartment, a drain pipe 804 connected to the outlet end of the water pump 801, and a drainage trough 9 that cooperates with the drain pipe 804 is provided between the hull 1 and the mud compartment 2.

[0034] Furthermore, a second support rod 11 is fixed on the partition plate 3. An auxiliary frame 12 with the same shape as the track frame 4 is fixed at the end of the second support rod 11 away from the partition plate 3. An movable groove 121 is opened on the auxiliary frame 12. A slider 122 that is movably connected to the support plate 8 is slidably connected in the movable groove 121. The end of the support plate 8 away from the slider 122 is rotatably connected to the movable seat 7.

[0035] Specifically, when the movable seat 7 moves, it drives the support plate 8 to move. When the support plate 8 moves, it slides in the movable groove 121 through the slider 122. The slider 122 is located on the front side of the movable seat 7 along the forward direction of the track frame 4. When the sludge discharge pipe 6 is about to discharge sludge to the compartment at the initial position again, the water pump 801 connected to the water pump 803 on the outer support plate 8 of the movable seat 7 enters the compartment at the initial position first to extract the supernatant in the compartment at the initial position. The extracted supernatant is discharged to the drain trough 9 through the drain pipe 804. As the drive motor 701 continues to run, the sludge lower pipe 601 moves back to the upper side of the compartment at the initial position to discharge sludge to the compartment after the supernatant has been extracted for sediment settling and stratification. The water pump 803 then enters the next compartment to extract and discharge the supernatant that has completed the settling and separation, leaving sufficient loading space for the subsequent sludge discharge pipe 6 to continue discharging sludge.

[0036] Reference Figure 2 and Figure 4 As a preferred embodiment, based on the above method, a hydraulic cylinder 10 is further fixed on the support plate 8, the piston rod of the hydraulic cylinder 10 is connected to the lifting plate 1001, and a second telescopic pipe 1002 for connecting the water pumping pipe 802 and the water pumping hose 803 is fixed on the lifting plate 1001.

[0037] Specifically, as the sludge discharge pipe 6 circulates and discharges sludge into each compartment, the sludge and sand accumulation in the compartment increases, and the liquid level of the supernatant rises. By setting up a hydraulic cylinder 10 to push the lifting plate 1001 upward, the lifting plate 1001 drives the pumping hose 803 upward through the second telescopic pipe 1002, so that the height of the pumping hose 803 in pumping the supernatant in the compartment is raised each time, avoiding the pumping hose 803 from pumping the deposited sludge and sand, and ensuring the discharge effect of excess water in the sludge compartment 2.

[0038] This invention also discloses a method for using a large-capacity trailing suction hopper dredger to increase sediment loading capacity, comprising the following steps: S1: When the trailing suction hopper is working, the lower mud pipe 601 of the mud discharge pipe 6 is located on the upper side of the compartment in the initial position. The mud is extracted by the mud suction pipe 604 of the mud discharge pipe 6, and then the mud discharge pipe 6 discharges the extracted mud into the mud compartment 2. S2: Control the operation of drive motor 701. The output shaft of drive motor 701 drives drive gear 702 to mesh with toothed plate 403 on track frame 4, so that moving seat 7 moves along track frame 4. When mud discharge pipe 6 moves with moving seat 7, mud discharge pipe 6 continuously discharges mud into each compartment in sequence. S3: The mud discharged into the compartment is not impacted by the mud in other compartments, allowing the mud entering the compartment sufficient time to settle and separate into layers, effectively separating the mud and water, until the mud discharge pipe 601 of the mud discharge pipe 6 moves back to the upper side of the compartment. S4: After the mud discharge pipe 6 moves one revolution with the track frame 4, each compartment in the mud chamber 2 is filled with mud. When the mud discharge pipe 6 is about to discharge mud to the compartment at the initial position again, the water pump 801 connected to the pump hose 803 on the outer support plate 8 of the moving seat 7 enters the compartment at the initial position first to extract the supernatant in the compartment at the initial position. The extracted supernatant is discharged to the drain tank 9 through the drain pipe 804. S5: As the drive motor 701 continues to run, the mud pipe 601 moves back to the upper side of the compartment at the initial position, and discharges mud again from the compartment after the supernatant has been extracted to allow the mud and sand to settle and separate. Meanwhile, the water pumping hose 803 enters the next compartment to extract and discharge the supernatant that has been settled and separated, leaving enough loading space for the subsequent mud discharge pipe 6 to continue discharging mud until all compartments in mud chamber 2 are filled with mud and sand.

10. A method of using a large-capacity trailing suction hopper dredger for increasing sediment loading capacity according to claim 9, characterized in that, Includes the following steps: S1: When the trailing suction hopper is working, the lower mud pipe (601) of the mud discharge pipe (6) is located on the upper side of the compartment in the initial position. The mud is extracted by the mud suction pipe (604) of the mud discharge pipe (6), and then the mud discharge pipe (6) discharges the extracted mud into the mud tank (2). S2: Control the operation of the drive motor (701). The output shaft of the drive motor (701) drives the drive gear (702) to mesh with the toothed plate (403) on the track frame (4) to make the moving seat (7) move along the track frame (4). When the mud discharge pipe (6) moves with the moving seat (7), it continuously discharges the mud from the mud discharge pipe (6) into each compartment in sequence. S3: The mud discharged into the compartment is not impacted by the mud in other compartments, allowing the mud entering the compartment to have sufficient time to settle and separate into layers, effectively separating the mud and water until the mud discharge pipe (601) moves back to the upper side of the compartment. S4: After the mud discharge pipe (6) moves one round with the track frame (4), each compartment in the mud chamber (2) is filled with mud. When the mud discharge pipe (6) is about to discharge mud to the compartment at the initial position again, the water pump (801) connected to the pump hose (803) on the outer support plate (8) of the moving seat (7) enters the compartment at the initial position first to extract the supernatant in the compartment at the initial position. The extracted supernatant is discharged to the drain tank (9) through the drain pipe (804). S5: As the drive motor (701) continues to run, the mud pipe (601) moves back to the upper side of the compartment at the initial position, and discharges mud again to allow the mud and sand to settle and separate after the supernatant has been extracted. Meanwhile, the water pumping hose (803) enters the next compartment to extract and discharge the supernatant that has been settled and separated, leaving enough loading space for the subsequent mud discharge pipe (6) to continue discharging mud until all compartments in the mud tank (2) are filled with mud and sand.
