Abstract
Description
Technical Field
[0001] This invention relates to the field of loading technology, and in particular to a loading device for a trailing suction hopper dredger. Background Technology
[0002] The loading process of existing trailing suction hopper dredgers is divided into a loading stage and an overflow stage. In the loading stage, the mud pump transports the dredged mud from the dredging equipment into the mud tank through the mud discharge pipe until the mud level in the tank reaches the height of the overflow pipe. Then, the overflow stage begins. As the mud pump continues to transport the dredged mud into the mud tank, the coarse particles of mud and sand in the mud gradually settle in the mud tank, while the water and low-concentration mud that cannot settle overflow out of the tank through the overflow pipe.
[0003] However, during the dredging of fine-grained silt, the continuous discharge of slurry impacts the slurry already discharged into the slurry chamber, causing turbulence and making it difficult for fine-grained silt to settle. As the overflow process continues, the concentration of slurry overflowing from the chamber through the overflow pipe is almost equal to the concentration of slurry pumped into the chamber. The overflowing slurry greatly increases the turbidity of the water area under construction, adversely affecting the ecosystem. Especially when dredging contaminated silt, the high concentration of pollutants entering the water body through the overflow can spread under the action of water flow or tides, causing secondary pollution in a wider area of water.

[0007] Preferably, both the first telescopic pipe and the second telescopic pipe are composed of multiple slidingly connected pipe fittings, and the pipe fitting diameter at the water outlet end of the first telescopic pipe and the second telescopic pipe is larger than the pipe fitting diameter at the water inlet end.

[0009] Preferably, the mounting plate assembly includes a support plate fixed to the bottom of the sleeve, and a horizontal plate is connected to each of the two support plates at the bottom of the sleeve. A connecting rod is slidably connected between the two horizontal plates. A connecting seat that is fixed to the bending tube is fixed on the connecting rod. A first elastic element sleeved on the outside of the connecting rod is connected between the connecting seat and the horizontal plate.
[0010] Preferably, a pull rope is fixedly connected to the support plate, and the end of the pull rope away from the support plate passes through the connecting seat and is fixedly connected to the lower end of the second telescopic tube. A guide part that is slidably connected to the pull rope is fixed on the connecting seat.
[0011] Preferably, the movable tube is slidably connected to the bottom of the second telescopic tube, and a second elastic element is provided between the end of the movable tube and the outer wall of the second telescopic tube. The movable tube is composed of two non-connected tube sections, and each tube section has an inlet at its top that is connected to the bottom opening of the second telescopic tube.
[0012] Preferably, the bottom of the second telescopic tube is configured as an outwardly flared arc shape to accommodate excess mud when the movable tube seals the bottom opening of the second telescopic tube.
[0013] Preferably, a connecting rod is fixed at the end of the movable tube away from the second telescopic tube, and a force-bearing plate is provided at the end of the connecting rod away from the movable tube to move against the inner wall or partition of the mud chamber, and a plurality of ball bearings are provided on the force-bearing plate.
[0014] Preferably, each of the several individual compartments divided by the mud chamber is equipped with an overflow valve, and an energy dissipation box is provided between the mud conveying pipe and the mud discharge pipe to reduce the kinetic energy of the mud when it is pumped out.
[0015] Compared with the prior art, the present invention provides a loading device for a trailing suction hopper dredger, which has the following beneficial effects: 1. The loading equipment of this trailing suction hopper dredger divides the mud hopper into several independent compartments, so that loading each compartment will not affect the sedimentation of other already loaded mud and sand. It also ensures that the mud discharge pipe always discharges the mud to the side close to the inner wall or partition of the compartment, further reducing the disturbance of the mud to the water in other parts of the same compartment, facilitating mud and sand deposition, and reducing the turbidity of the mud at the overflow point.
[0016] 2. The loading equipment of this trailing suction hopper dredger, through the conveying component and the plate-mounting component, drives the sludge discharge pipe to come into contact with the inner wall or partition of the sludge tank. The lower discharge port of the sludge discharge pipe is located on the lower side of the tank. As the sludge is discharged into the tank, the sludge discharge pipe continuously contracts and rises, thereby ensuring that the discharge port of the sludge discharge pipe and the liquid level in the tank always maintain the same distance. This avoids the discharge port of the sludge discharge pipe being too high above the liquid level in the tank, which would cause the falling sludge to have an excessive impact force on the liquid surface. This effectively reduces the disturbance of the discharged sludge to the water in the tank and ensures rapid sedimentation of sludge and sand. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] Example: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A trailing suction hopper dredger loading device includes a mud hopper 1. Several partitions 2 are fixed inside the mud hopper 1, dividing the mud hopper 1 into several independent compartments. A mud conveying pipe 3 is fixed to the top of the mud hopper 1 via a bracket. A mud discharge pipe 4 is fixed to the end of the mud conveying pipe 3. A conveying assembly for conveying the displacement of the mud discharge pipe 4 is fixed to the top of the mud hopper 1. The conveying assembly is equipped with a plate assembly for driving the end of the mud discharge pipe 4 to move against the partitions 2 or the inner wall of the mud hopper 1.
[0023] Furthermore, the mud discharge pipe 4 includes a first telescopic pipe 401 fixedly connected to the mud conveying pipe 3, a bent pipe 402 fixedly connected to the end of the first telescopic pipe 401 away from the mud discharge pipe 4, a second telescopic pipe 403 provided at the lower end of the bent pipe 402, and a movable pipe 404 connected to the bottom of the second telescopic pipe 403. The end of the movable pipe 404 away from the second telescopic pipe 403 is movable and abuts against the inner wall of the mud chamber 1 or the partition 2.
[0024] Specifically, the baffle 2 divides the mud chamber 1 into several individual chambers along its length. The conveying component drives the mud discharge pipe 4 to move along the length of the mud chamber 1, so that the mud discharge pipe 4 loads mud into each chamber one by one. By dividing the mud chamber 1 into several independent chambers, the loading of each chamber will not affect the sedimentation of other chambers that have already been loaded. In addition, the plate component ensures that the mud discharge pipe 4 always discharges mud to the side close to the inner wall of the chamber or the baffle 2, further reducing the disturbance of the mud to the water in other locations in the same chamber, facilitating the sedimentation of mud and reducing the turbidity of the mud discharged from the overflow point.
[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As a preferred technical solution of the present invention, the first telescopic pipe 401 and the second telescopic pipe 403 are both composed of multiple slidingly connected pipe fittings. The pipe fitting diameter at the water outlet end of the first telescopic pipe 401 and the second telescopic pipe 403 is larger than the pipe fitting diameter at the water inlet end. Specifically, by making the pipe fitting diameter at the water outlet end larger than the pipe fitting diameter at the water inlet end, it is easier to make the water flow velocity at the water outlet end lower than the water flow velocity at the water inlet end, thereby reducing the impact kinetic energy of the mud discharged into the chamber.
[0026] Reference Figure 1 , Figure 2 and Figure 3 As a preferred technical solution of the present invention, the conveying assembly includes a support plate 5 fixedly mounted on the top of the mud chamber 1. A conveying motor 501 is fixedly mounted on the support plate 5. A screw 502 connected to the output shaft of the conveying motor 501 is rotatably connected to the support plate 5. Two sleeves 503 are threadedly connected to the screw 502. Both sleeves 503 are connected to the plate-mounting assembly. Specifically, when the conveying assembly is working, the conveying motor 501 is controlled to run. The output shaft of the conveying motor 501 drives the screw 502 to rotate on the support plate 5. When the screw 502 rotates, the sleeves 503 connected to the outer thread move along the axial direction of the screw 502, thereby causing the sleeves 503 to drive the plate-mounting assembly to move, so that the plate-mounting assembly discharges the mud discharged from the mud-draining pipe 4 into each chamber one by one.
[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As a preferred technical solution of the present invention, the mounting plate assembly includes a support plate 6 fixedly disposed at the bottom of the sleeve 503, a horizontal plate 601 connected to the support plate 6 at the bottom of the two sleeves 503, a connecting rod 602 slidably connected between the two horizontal plates 601, a connecting seat 603 fixedly disposed on the connecting rod 602 and fixedly connected to the bent tube 402, and a first elastic element 604 sleeved on the outside of the connecting rod 602 connected between the connecting seat 603 and the horizontal plate 601.
[0028] Furthermore, a pull rope 7 is fixedly connected to the support plate 6. The end of the pull rope 7 away from the support plate 6 passes through the connecting seat 603 and is fixedly connected to the lower end of the second telescopic tube 403. A guide part 6031 that is slidably connected to the pull rope 7 is fixedly provided on the connecting seat 603.
[0029] Specifically, when the conveying assembly moves the plate assembly via the two sleeves 503, the two sleeves 503, through the connecting rod 602 and the first elastic element 604, drive the bent tube 402 connected to the connecting seat 603 to move laterally, causing the first telescopic tube 401 to be stretched. When the movable tube 404 at the end of the second telescopic tube 403 abuts against the partition 2 or the inner wall of the mud chamber 1, the mud conveying pipe 3 is controlled to discharge the extracted mud into the mud chamber 1. It should be noted that the second telescopic tube 403 is initially in an extended state, that is, the second telescopic tube 403 drives the movable tube 404 to be placed on the lower side of the chamber, to avoid the discharge port of the mud lowering pipe 4 being too high from the bottom liquid level of the chamber, which would cause... The falling mud has an excessive impact on the liquid surface. As the conveying assembly continues to operate, the two sleeves 503 continue to move laterally along the screw 502. However, because the movable pipe 404 is in contact with the partition plate 2, the mud-draining pipe 4 cannot move laterally with the sleeves 503. As the sleeves 503 move, the sleeve 503 at the front of the movement direction pulls the pull rope 7 through the support plate 6. The pull rope 7, guided by the connecting seat 603 and the guide part 6031, applies a pulling force to the lower side of the second telescopic pipe 403 (it should be noted that the pull rope 7 connected to the other sleeve 503 does not apply a pulling force to the second telescopic pipe 403), causing the second telescopic pipe 403 to contract and rise, and the mud-draining pipe 4 moves laterally with the screw 503. The mud discharge chamber continuously contracts and rises, ensuring that the discharge port of the mud discharge pipe 4 remains at the same distance from the liquid level in the chamber. This prevents the discharge port of the mud discharge pipe 4 from being too high above the liquid level, which would cause excessive impact force of the falling mud on the liquid surface. This effectively reduces the disturbance of the discharged mud to the water in the chamber, ensuring rapid sedimentation of mud and sand. After the sleeve 503, located at the front of the moving direction, passes the partition 2 of the next unloaded chamber, the retracted second telescopic pipe 403 drives the movable pipe 404 to move to the upper side of the partition 2. The movable pipe 404 is no longer limited by the partition 2, allowing the connecting seat 603 to reset and move under the elastic force of the first elastic element 604. The connecting seat 603 moves closer to the sleeve 503 located on the front side of the moving direction. As the connecting seat 603 approaches the sleeve 503 on the front side of the moving direction, the pull rope 7 is released. The second telescopic tube 403 and the movable tube 404 move down under their own gravity. The movable tube 404 enters the compartment to be loaded from the compartment that has been loaded. The movable tube 404 abuts against the inner wall of the compartment to be loaded, i.e., the partition 2, so that the movable tube 404 and the partition 2 are close together. The mud discharge pipe 4 always discharges mud to the side close to the inner wall of the compartment or the partition 2, further reducing the disturbance of the mud to the water in other locations of the same compartment, facilitating the sedimentation of mud and sand, and reducing the turbidity of the mud discharged from the overflow point.
[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As a preferred technical solution of the present invention, the movable tube 404 is slidably connected to the bottom of the second telescopic tube 403. A second elastic element 8 is provided between the end of the movable tube 404 and the outer wall of the second telescopic tube 403. The movable tube 404 is composed of two non-connected tubes. Each tube has an inlet 4041 at the top that is connected to the bottom opening of the second telescopic tube 403.
[0031] Furthermore, the bottom of the second telescopic pipe 403 is configured as an outwardly flared arc shape to accommodate excess mud when the movable pipe 404 seals the bottom opening of the second telescopic pipe 403.
[0032] Specifically, the conveying assembly can reciprocate along the axial direction of the screw 502. When moving in one direction, the sleeve 503 at the front of the moving direction passes the partition 2 of the next unloaded compartment. The retracted second telescopic tube 403 drives the movable tube 404 to move to the upper side of the partition 2. The movable tube 404 is no longer limited by the partition 2, so the connecting seat 603 resets and moves under the elastic force of the first elastic element 604 and approaches the sleeve 503 at the front of the moving direction. As the connecting seat 603 approaches the sleeve 503 at the front of the moving direction, the pull rope 7 is released. The second telescopic tube 403 and the movable tube 404 move down under their own gravity. The movable tube 404 enters the compartment to be loaded from the already loaded compartment. The movable tube 404 abuts against the inner wall of the compartment to be loaded, i.e., the partition 2. When the movable tube 404 abuts against the partition 2, the second elastic element 8 can... The collision force between the movable pipe 404 and the partition 2 is weakened to avoid damage to the movable pipe 404 or the partition 2. When the movable pipe 404 is not in contact with the partition 2, the second elastic element 8 drives the movable pipe 404 to reset at the lower part of the second telescopic pipe 403. The movable pipe 404 blocks the bottom opening of the second telescopic pipe 403. At this time, the mud that continues to be discharged is stored in the arc-shaped pipe at the bottom of the second telescopic pipe 403. After the movable pipe 404 comes into contact with the next partition 2, the movable pipe 404 slides in the second telescopic pipe 403, so that the second telescopic pipe 403 is connected to the movable pipe 404 through the feed port 4041, realizing the mud-attached discharge work near the partition 2. It should be noted that the movable pipe 404 is composed of two unconnected pipe sections, which makes it convenient for the mud-lowering pipe 4 to abut against the partition 2 on the other side of the cabin and discharge mud when the subsequent conveying component drives the attachment component back.
[0033] Reference Figure 6As a preferred technical solution of the present invention, a connecting rod 9 is fixedly provided at one end of the movable tube 404 away from the second telescopic tube 403. A force-bearing plate 901 is provided at one end of the connecting rod 9 away from the movable tube 404, which moves against the inner wall of the mud chamber 1 or the partition 2. A plurality of balls 902 are provided on the force-bearing plate 901. Specifically, the force-bearing plate 901 abuts against the partition 2 through the balls 902, which facilitates the reduction of wear on the force-bearing plate 901 and the partition 2 when the second telescopic tube 403 drives the movable tube 404 to move upward, thus ensuring the service life of the force-bearing plate 901 and the partition 2.
[0034] Reference Figure 1 and Figure 7 As a preferred technical solution of the present invention, the mud chamber 1 is divided into several individual chambers by the partition 2, each of which is equipped with an overflow valve 10. An energy dissipation box 11 is provided between the mud conveying pipe 3 and the mud discharge pipe 4 to reduce the kinetic energy when the mud is pumped out. Specifically, by setting the overflow valve 10, it is convenient to discharge the water in the chamber and ensure the mud and sand concentration in the chamber. The energy dissipation box 11 provided between the mud conveying pipe 3 and the mud discharge pipe 4 effectively reduces the kinetic energy when the mud is discharged and reduces the disturbance intensity of the mud in the chamber.
[0035] Working principle: When the conveying component is working, it controls the operation of the conveying motor 501. The output shaft of the conveying motor 501 drives the screw 502 to rotate on the support plate 5. When the screw 502 rotates, the sleeve 503 connected by the outer thread moves along the axial direction of the screw 502, thereby causing the sleeve 503 to drive the plate assembly to move. When the conveying assembly moves the plate assembly through the two sleeves 503, the two sleeves 503 drive the bent tube 402 connected to the connecting seat 603 to move laterally through the connecting rod 602 and the first elastic element 604, so that the first telescopic tube 401 is stretched. When the movable tube 404 at the end of the second telescopic tube 403 abuts against the partition 2 or the inner wall of the mud chamber 1, the mud conveying pipe 3 is controlled to discharge the extracted mud into the mud chamber 1. As the conveying assembly continues to work, the two sleeves 503 continue to move laterally along the screw 502. However, because the movable pipe 404 is in contact with the partition 2, the mud discharge pipe 4 cannot move laterally with the sleeves 503. As the sleeves 503 move, the sleeve 503 at the front of the moving direction pulls the pull rope 7 through the support plate 6. The pull rope 7 applies a pulling force to the lower side of the second telescopic pipe 403 through the guide of the connecting seat 603 and the guide part 6031, causing the second telescopic pipe 403 to contract and rise. The mud discharge pipe 4 continuously contracts and rises as the mud is discharged into the tank, thereby ensuring that the discharge port of the mud discharge pipe 4 is always at the same distance from the liquid level in the tank, avoiding the discharge port of the mud discharge pipe 4 being too high from the liquid level in the tank, which would cause the falling mud to have an excessive impact force on the liquid surface. After the sleeve 503, located at the front of the moving direction, passes the bulkhead 2 of the next unloaded compartment, the retracted second telescopic tube 403 drives the movable tube 404 to move to the upper side of the bulkhead 2. The movable tube 404 is no longer limited by the bulkhead 2, causing the connecting seat 603 to reset and move closer to the sleeve 503 located at the front of the moving direction under the elastic force of the first elastic element 604. As the connecting seat 603 approaches the sleeve 503 at the front of the moving direction, the pull rope 7 is released, and the second telescopic tube... 403 and movable pipe 404 move downwards under their own gravity. Movable pipe 404 enters the compartment to be loaded from the already loaded compartment. Movable pipe 404 again comes into contact with the inner wall of the compartment to be loaded, i.e., the bulkhead 2, so that movable pipe 404 and bulkhead 2 are in close contact. The sludge discharge pipe 4 always discharges sludge to the side close to the inner wall of the compartment or the bulkhead 2, further reducing the disturbance of the sludge to the water in other parts of the same compartment, facilitating the deposition of sludge and sand, and reducing the turbidity of the sludge discharged from the overflow point. After the sleeve 503, located at the front of the moving direction, passes the bulkhead 2 of the next unloaded compartment, the retracted second telescopic tube 403 drives the movable tube 404 to move to the upper side of the bulkhead 2. The movable tube 404 is no longer limited by the bulkhead 2, causing the connecting seat 603 to reset and move closer to the sleeve 503 located at the front of the moving direction under the elastic force of the first elastic element 604. As the connecting seat 603 approaches the sleeve 503 at the front of the moving direction, the pull rope 7 is released, and the second telescopic tube... 403 and movable pipe 404 move downward under their own gravity. Movable pipe 404 enters the compartment to be loaded from the compartment that has been loaded. Movable pipe 404 comes into contact with the inner wall of the compartment to be loaded, i.e., the bulkhead 2, so that movable pipe 404 and bulkhead 2 are close together. The mud discharge pipe 4 always discharges mud to the side close to the inner wall of the compartment or the bulkhead 2, further reducing the disturbance of the mud to the water in other parts of the same compartment, facilitating the sedimentation of mud and sand, and reducing the turbidity of the mud discharged from the overflow point.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
