Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, and more specifically, to a net-type boat-towed scraper for removing floating mud layers. Background Technology

[0002] With the development of the economy and society, human demand for the exploration and utilization of the ocean and its resources is increasing. These demands have spurred the rapid development of various fields of dredging engineering and marine engineering. In dredging engineering, the trailing suction hopper (LTH) method is one of the typical methods for excavating materials on the seabed. The typical equipment is the LHT dredger, and the dredger head is the working component of the LHT dredger that excavates soil layers. It is connected to the suction pipe through a flange installed at the end. The function of the dredger head can be summarized as using the rake teeth to break down the soil structure to excavate underwater silt and other materials. The excavated silt is then mixed with the water entering the dredger head to form slurry, which is then transported to the predetermined location by fluid transport. During the dredging process of the LHT dredger, some silt will be suspended on the water surface due to the dredging and agitation, forming a floating silt layer. Therefore, to prevent a large amount of floating silt from affecting the operation of the LHT dredger and the dredging work, a net-type tug scraper is generally used in conjunction with the LHT dredger to remove the floating silt layer on the water surface.

[0003] Current net-type boat tow scrapers still have the following drawbacks in use: 1. The canvas and steel wire rope in the net-type boat tow scraper are fixedly connected, making it difficult to quickly install or remove when the canvas is damaged or needs to be replaced, which is very inconvenient; 2. The canvas usually needs to be tied between two trailing suction hopper dredgers with steel wire ropes for towing. When only one trailing suction hopper dredger is working, it is not convenient to install the scraper for removing floating mud; 3. When the floating mud removal is finished, the steel wire rope needs to be manually rolled up to collect the canvas, which is not only time-consuming and labor-intensive, but also prone to tangling and knotting when the steel wire rope is rolled up haphazardly, affecting subsequent use. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing net-type boat towing scrapers, such as the inability to quickly install and disassemble the canvas and wire rope, the inability to be used with a single trailing suction hopper vessel, and the tendency for the wire rope to become tangled and knotted when winding it up.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A net-type boat tug scraper for removing silt layer includes a fixed frame and a canvas disposed on the inner wall of the fixed frame, and further includes:

[0007] The take-up and release mechanism includes two storage frames, a winding assembly disposed inside the storage frames, and a steel wire rope disposed between the winding assembly and the fixed frame.

[0008] A connecting component is disposed between the fixed frame and the wire rope, and is used for quick installation and disassembly of the wire rope and the fixed frame;

[0009] The compression mechanism is provided inside the box on the side wall of the storage frame. The compression mechanism can compress the wire rope when the winding mechanism is winding the wire rope to keep the wire rope in a taut state.

[0010] As a preferred technical solution of this application, the connecting component includes a fixed cylinder symmetrically arranged on both sides of the fixed frame, an insertion post arranged at the end of the wire rope away from the winding component, a limiting post arranged on the side wall of the insertion post, a slot opened on the side wall of the fixed cylinder, a sliding groove arranged on the side wall of the fixed cylinder and connected to the slot, and a card slot arranged on the side wall of the fixed cylinder and connected to the sliding groove.

[0011] As a preferred technical solution of this application, the slot, sliding groove and card slot cooperate with the limiting post, and the inner walls of the slot, sliding groove and card slot are all provided with rubber pads.

[0012] As a preferred technical solution of this application, a spring block is slidably connected to the inner wall of the fixed cylinder, and a first spring is provided between the spring block and the bottom wall of the fixed cylinder.

[0013] As a preferred technical solution of this application, the winding assembly includes a motor disposed at the top of the storage frame, a rotating shaft disposed at the output shaft of the motor, and drums symmetrically sleeved on both sides of the rotating shaft rod wall. The side wall of the storage frame is provided with a sliding groove, and the end of the wire rope away from the insertion post passes through the sliding groove and connects to the drum.

[0014] As a preferred technical solution of this application, the extrusion mechanism includes a screw rotatably disposed at the top and bottom of the housing, a screw cylinder threaded on the screw rod wall and slidably connected to the housing, a pressure block disposed at the bottom of the screw cylinder, a support plate disposed at the edges on both sides of the storage frame, a stop block disposed on the support plate and cooperating with the pressure block, a rubber block disposed on the opposite side of the pressure block and the stop block, a first rotating rod rotatably disposed on the side wall of the housing, a first driving bevel gear disposed at one end of the first rotating rod located inside the housing, and a first driven bevel gear disposed at one end of the screw located inside the housing and meshing with the first driving bevel gear. The storage frame is also provided with a transmission assembly for driving the first rotating rod to rotate.

[0015] As a preferred technical solution of this application, the transmission assembly includes a second rotating rod and a third rotating rod rotatably disposed on the side wall of the storage frame, a second driving bevel gear disposed on the rotating shaft rod wall, a second driven bevel gear disposed on the inner rod wall of the second rotating rod located in the storage frame and meshing with the second driving bevel gear, a complete gear disposed on the outer rod wall of the second rotating rod located in the storage frame, an incomplete gear disposed on the rod wall of the third rotating rod, and a belt disposed between the third rotating rod and the first rotating rod.

[0016] As a preferred technical solution of this application, the bottom of the storage frame is provided with a protective shell, and a pulling mechanism is provided inside the protective shell. The pulling mechanism includes a curved rod that is slidably disposed between the protective shell and the storage frame, a limiting sleeve sleeved outside the steel wire rope, and a reciprocating component disposed inside the protective shell for pushing the curved rod back and forth. One end of the curved rod located inside the storage frame is connected to the limiting sleeve.

[0017] As a preferred technical solution of this application, the reciprocating assembly includes a third driving bevel gear disposed at one end of the rotating shaft extending into the inner end of the protective shell, a fourth rotating rod rotatably disposed on the inner wall of the protective shell, a third driven bevel gear and a cam disposed on the wall of the fourth rotating rod, a pulley disposed at one end of the crank rod located inside the protective shell, and a second spring disposed on the wall of the crank rod.

[0018] As a preferred technical solution of this application, the storage frame is provided with stiffening plates on the side wall, the stiffening plates are provided with positioning plates on the side wall, the top of the fixing frame is provided with several floats, and the bottom of the fixing frame is provided with several anchor balls.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. When a scraper is needed to treat the floating mud layer on the water surface, the connecting components are used to first insert the plug on the wire rope into the fixed cylinder. Then, the plug is rotated so that the limiting post on the side wall of the plug slides into the sliding groove through the slot. At this time, the set spring block and the first spring can push the plug so that the limiting post on the plug springs into the slot, quickly fixing the plug and the fixed cylinder. This allows for the rapid installation of the wire rope and the fixed frame. By squeezing the plug and then reversing the plug, the limiting post slides back into the slot, allowing the plug and the fixed cylinder to be disassembled and separated. This solves the problem in the existing technology that the wire rope and the fixed frame cannot be installed and disassembled, making it inconvenient to maintain and replace the canvas inside the fixed frame.

[0021] 2. By fixing two storage frames to both sides of the suction hopper, the canvas can be installed on one suction hopper for operation. Through the set up winding and unwinding mechanism, the motor can be started to work, and the rotating shaft drives the drum to rotate forward and backward, thereby winding and unwinding the steel wire rope. This allows for the automatic retrieval of the fixed frames and the canvas, solving the problems of the existing technology where the canvas needs to be installed on two suction hoppers and where it is time-consuming and labor-intensive to manually pull the steel wire rope to retrieve the canvas.

[0022] 3. When the wire rope is automatically wound up by the winding mechanism, the transmission component can drive the first rotating rod to rotate. At this time, the first driving bevel gear, the second driven bevel gear, the screw and the screw drum can drive the pressure block to move closer to the stop block, thereby squeezing the wire rope and keeping it in a taut state when it is wound up. This ensures that the wire rope is tightly wound on the drum and prevents it from becoming loose. In addition, the reciprocating component and the pulling mechanism can pull the wound wire rope up and down, making it easier to evenly wind the wire rope onto the drum. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0038] like Figures 1 to 4 As shown, this embodiment proposes a net-type boat tow scraper for removing floating mud layers, including a fixed frame 1 and a canvas 2 disposed on the inner wall of the fixed frame 1. It also includes a winding and unwinding mechanism, a connecting component, and a squeezing mechanism. The winding and unwinding mechanism includes two storage frames 3, a winding component disposed inside the storage frames 3, and a steel wire rope 6 disposed between the winding component and the fixed frame 1. The connecting component is disposed between the fixed frame 1 and the steel wire rope 6 for quick installation and disassembly of the steel wire rope 6 and the fixed frame 1. The side wall of the storage frame 3 is provided with a box 10. The squeezing mechanism is disposed inside the box 10. The squeezing mechanism can squeeze the steel wire rope 6 when the winding and unwinding mechanism is winding it to keep the steel wire rope 6 in a taut state.

[0039] When it is necessary to remove the floating mud layer generated by the trailing suction hopper dredging vessel, the wire rope 6 and the fixed frame 1 are quickly installed through the set connecting mechanism, saving time and making it easy to disassemble the fixed frame 1 to clean and replace the canvas 2 on the inside. Then, the two storage frames 3 are installed on a trailing suction hopper vessel. The fixed frame 1 and the canvas 2 can be moved in the water by the operation of one trailing suction hopper vessel to absorb and remove the floating mud layer, improving the adaptability of the equipment. The set winding and unwinding mechanism can automatically wind and unwind the wire rope 6, eliminating the need for manual pulling of the wire rope 6 to wind and unwind the canvas 2, saving time and manpower. When winding the wire rope 6, the set compression mechanism can also compress the wire rope 6, so that the wire rope 6 is in a taut state when it is wound, thus tightly winding the wire rope 6 onto the drum 5 and preventing the wire rope 6 from loosening after winding.

[0040] The storage frame 3 has a stiffening plate 22 on its side wall, and a positioning plate 2201 on the side wall of the stiffening plate 22. The top of the fixed frame 1 has several buoys 23, and the bottom of the fixed frame 1 has several anchor balls 24. The storage frame 3 can be installed on the suction dredger by the positioning plate 2201 and bolts. The anchor balls 24 can make the fixed frame 1 and the canvas 2 sink into the water. The buoys 23 can prevent the fixed frame 1 from sinking completely into the water, so that the top of the fixed frame 1 is flush with the water surface. The canvas 2, which is submerged in the water, can absorb and collect the floating mud layer.

[0041] like Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the connecting assembly further includes a fixed cylinder 7 symmetrically arranged on both sides of the fixed frame 1, an insertion post 8 arranged at the end of the wire rope 6 away from the winding assembly, a limiting post 801 arranged on the side wall of the insertion post 8, a slot 701 opened on the side wall of the fixed cylinder 7, a sliding groove 702 arranged on the side wall of the fixed cylinder 7 and connected to the slot 701, and a locking groove 703 arranged on the side wall of the fixed cylinder 7 and connected to the sliding groove 702.

[0042] The slot 701, sliding groove 702 and card slot 703 cooperate with the limiting post 801, and the inner walls of the slot 701, sliding groove 702 and card slot 703 are all provided with rubber pads.

[0043] A spring block 9 is slidably connected to the inner wall of the fixed cylinder 7, and a first spring 901 is provided between the spring block 9 and the inner bottom wall of the fixed cylinder 7.

[0044] When it is necessary to install the wire rope 6 and the fixing frame 1 together, first insert the pin 8 on the wire rope 6 into the fixing cylinder 7, and let the limiting pin 801 on the side wall of the pin 8 slide into the sliding groove 702 along the slot 701. The pin 8 will also squeeze the spring block 9 to compress the first spring 901. Then, rotate the pin 8 to drive the limiting pin 801 to rotate into the sliding groove 702 and be flush with the slot 703. At this time, release the pin 8. The first spring 901 will be released from its force, which will drive the spring block 9 and the pin 8 to rebound and reset, so that the limiting pin 801 slides into the slot 703, which facilitates the installation of the pin 8 and the fixing cylinder 7. The system allows for quick locking, enabling rapid installation of the wire rope 6 and the fixing frame 1. When it is necessary to disassemble the fixing frame 1 and the wire rope 6, the insert post 8 can be pressed into the fixing cylinder 7 again, causing the limiting post 801 to slide into the sliding groove 702. Then, the insert post 8 can be rotated to slide the limiting post 801 to a position flush with the slot 701 and the insert post 8 can be released. At this time, the first spring 901 will be released again, causing the spring block 9 to rebound and eject the insert post 8 from the fixing cylinder 7, thereby enabling the fixing frame 1 to be quickly disassembled, facilitating the cleaning or replacement of the canvas 2 inside the fixing frame 1.

[0045] like Figure 5 As shown, in a preferred embodiment, based on the above method, the winding assembly further includes a motor 4 disposed on the top of the storage frame 3, a rotating shaft 401 disposed on the output shaft of the motor 4, and a drum 5 symmetrically sleeved on both sides of the shaft wall of the rotating shaft 401. The side wall of the storage frame 3 is provided with a groove 301, and the end of the wire rope 6 away from the insertion post 8 passes through the groove 301 and is connected to the drum 5.

[0046] The start motor 4 drives the drum 5 on the rotating shaft 401 to rotate in both directions, which can wind up and unwind the wire rope 6, thereby automatically wind up and unwind the fixed frame 1 and the canvas 2. It eliminates the need for manual pulling of the wire rope 6 to wind up and unwind the canvas 2, thus saving time and effort.

[0047] like Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 12As shown, in a preferred embodiment, based on the above method, the extrusion mechanism further includes a screw 12 rotatably disposed at the top and bottom of the housing 10, a screw cylinder 1201 threaded on the wall of the screw 12 and slidably connected to the housing 10, a pressure block 13 disposed at the bottom of the screw cylinder 1201, a support plate 16 disposed at the edges on both sides of the storage frame 3, a stop block 1601 disposed on the support plate 16 and cooperating with the pressure block 13, a rubber block 1301 disposed on the opposite side of the pressure block 13 and the stop block 1601, a first rotating rod 11 rotatably disposed on the side wall of the housing 10, a first driving bevel gear 1101 disposed at one end of the first rotating rod 11 located inside the housing 10, and a first driven bevel gear 1202 disposed at one end of the screw 12 located inside the housing 10 and meshing with the first driving bevel gear 1101. The storage frame 3 is also provided with a transmission assembly for driving the first rotating rod 11 to rotate.

[0048] The transmission assembly includes a second rotating rod 14 and a third rotating rod 15 rotatably disposed on the side wall of the storage frame 3, a second driving bevel gear 402 disposed on the rod wall of the rotating shaft 401, a second driven bevel gear 1401 disposed on the inner rod wall of the second rotating rod 14 and meshing with the second driving bevel gear 402, a complete gear 1402 disposed on the outer rod wall of the second rotating rod 14, an incomplete gear 1501 disposed on the rod wall of the third rotating rod 15, and a belt 1502 disposed between the third rotating rod 15 and the first rotating rod 11.

[0049] When the motor 4 drives the rotating shaft 401 to rotate and wind the wire rope 6, the rotating shaft 401 drives the second rotating rod 14, which has a second driven bevel gear 1401, to rotate via the second driving bevel gear 402. The second rotating rod 14 drives the complete gear 1402 on its rod wall to rotate. The complete gear 1402 first contacts the toothed side of the incomplete gear 1501 and drives the incomplete gear 1501 to rotate a certain distance. When the complete gear 1402 contacts the toothless side of the incomplete gear 1501, the complete gear 1402 will no longer drive the incomplete gear 1501 to rotate. Therefore, the incomplete gear 1501 drives the first rotating rod 11 to rotate a certain distance via the third rotating rod 15 and the belt 1502. So the first rotating rod 11 then drives the screw 12 to rotate a certain distance via the first driving bevel gear 1101 and the first driven bevel gear 1202. Then, the screw barrel 1201 will move downwards a certain distance and stop. The downward-moving pressure block 13 will then approach the stop block 1601 to squeeze the wire rope 6. The rubber block 1301 will undergo buffer deformation to prevent the wire rope 6 from being completely clamped. Therefore, the clamped wire rope 6 can be kept taut when it is pulled and wound up, so that the wire rope 6 can be tightly wound and wound on the drum 5 to prevent the wire rope 6 from becoming loose. It should be noted that the screw barrel 1201 is slidably connected to the slide groove 301 on the side wall of the storage frame 3 through the slide rod 1203 and the slider 1204. Therefore, when the screw 12 rotates a certain distance, it can drive the screw barrel 1201 to move downwards a certain distance. In addition, a protective cover 21 can be set on the side wall of the storage frame 3 to shield and protect the components of the transmission component, preventing foreign objects from touching the transmission component and affecting the operation of the extrusion mechanism.

[0050] like Figure 5 and Figure 11 As shown, in a preferred embodiment, based on the above method, the bottom of the storage frame 3 is provided with a protective shell 20, and a pulling mechanism is provided inside the protective shell 20. The pulling mechanism includes a curved rod 17 slidably disposed between the protective shell 20 and the storage frame 3, a limiting sleeve 1701 sleeved on the outside of the wire rope 6, and a reciprocating assembly disposed inside the protective shell 20 for pushing the curved rod 17 back and forth. One end of the curved rod 17 located inside the storage frame 3 is connected to the limiting sleeve 1701.

[0051] The reciprocating assembly includes a third driving bevel gear 403 disposed at one end of the rotating shaft 401 extending into the interior of the protective housing 20, a fourth rotating rod 19 rotatably disposed on the inner wall of the protective housing 20, a third driven bevel gear 1901 and a cam 18 disposed on the rod wall of the fourth rotating rod 19, a pulley 1801 disposed at one end of the crank rod 17 located inside the protective housing 20, and a second spring 1702 disposed on the rod wall of the crank rod 17.

[0052] When the motor 4 drives the rotating shaft 401 to rotate and wind the wire rope 6, the rotating shaft 401 will also drive the fourth rotating rod 19, which is equipped with a third driven bevel gear 1901, to rotate through the third driving bevel gear 403 at its bottom. The fourth rotating rod 19 will then drive the cam 18 to rotate. When the cam 18 rotates to the point where its small end contacts the pulley 1801, it will squeeze the pulley 1801 and the crank rod 17 to slide downward and compress the second spring 1702. When the cam 18 rotates to the point where its large end contacts the pulley 1801, the second spring 1702 will be released from its force and drive the crank rod 17 to move upward and reset. Therefore, the crank rod 17 can be driven to move up and down back and forth, and when the wire rope 6 is wound, it can pull the wire rope 6 back and forth, so that the wire rope 6 can be evenly wound on the drum 5. This not only prevents the wire rope 6 from collapsing at one position on the drum 5, but also increases the winding amount of the drum 5.

[0053] The working principle of this invention is as follows: When it is necessary to remove the floating mud layer generated by the dredging vessel, the insert 8 on the wire rope 6 is first inserted into the fixed cylinder 7, and the limiting post 801 on the side wall of the insert 8 slides into the sliding groove 702 along the slot 701. The insert 8 also compresses the spring block 9, causing the first spring 901 to compress. Then, the insert 8 is rotated, causing the limiting post 801 to rotate into the sliding groove 702 and become flush with the slot 703. At this point, the insert 8 is released, and the first spring 901 is released from its force, causing the spring block 9 and the insert 8 to rebound and reset, allowing the limiting post 801 to slide into the slot 703, facilitating the removal of the insert 8. The fixing cylinder 7 is quickly locked in place, allowing for the rapid installation of the wire rope 6 and the fixing frame 1. When it is necessary to disassemble the fixing frame 1 and the wire rope 6, the insert post 8 can be pressed into the fixing cylinder 7 again, causing the limiting post 801 to slide into the sliding groove 702. Then, the insert post 8 is rotated so that the limiting post 801 slides to a position flush with the slot 701 and the insert post 8 is released. At this time, the first spring 901 will be released again, causing the spring block 9 to rebound and eject the insert post 8 from the fixing cylinder 7, thus enabling the fixing frame 1 to be quickly disassembled, facilitating the cleaning or replacement of the canvas 2 inside the fixing frame 1. Then, the storage frame 3 can be installed on the suction dredger using the positioning plate 2201 and bolts. The anchor ball 24 can make the fixing frame 1 and the canvas 2 sink into the water. The float 23 can prevent the fixing frame 1 from completely sinking into the water, keeping the top of the fixing frame 1 flush with the water surface. The submerged canvas 2 can then absorb and collect the floating mud layer. Furthermore, starting the motor 4 drives the drum 5 on the rotating shaft 401 to rotate in both directions, which can reel in and unreel the wire rope 6, thereby automatically reeling in and unreeling the fixed frame 1 and the canvas 2. This eliminates the need for manual pulling of the wire rope 6 to reel in and unreel the canvas 2, thus saving time and effort.When the motor 4 drives the rotating shaft 401 to rotate and wind the wire rope 6, the rotating shaft 401 drives the second rotating rod 14, which has a second driven bevel gear 1401, to rotate via the second driving bevel gear 402. The second rotating rod 14 drives the complete gear 1402 on its rod wall to rotate. The complete gear 1402 first contacts the toothed side of the incomplete gear 1501 and drives the incomplete gear 1501 to rotate a certain distance. When the complete gear 1402 contacts the toothless side of the incomplete gear 1501, the complete gear 1402 will no longer drive the incomplete gear 1501 to rotate. Therefore, the incomplete gear 1501 will drive the first rotating rod 11 to rotate a certain distance via the third rotating rod 15 and the belt 1502. So the first rotating rod 11 then drives the first driving bevel gear 15 to rotate via the first driving bevel gear 1401. The bevel gear 1101 and the first driven bevel gear 1202 drive the screw 12 to rotate a certain distance and then stop, which in turn drives the screw barrel 1201 to move downward a certain distance and then stop. Then, the downward-moving pressure block 13 approaches the stop block 1601 to squeeze the wire rope 6. The rubber block 1301 will undergo buffer deformation to prevent the wire rope 6 from being completely clamped. Therefore, when the clamped wire rope 6 is pulled and wound up, it can be kept in a taut state, so that the wire rope 6 can be tightly wound and wound on the drum 5, preventing the wire rope 6 from becoming loose. It should be noted that the screw barrel 1201 is slidably connected to the slide groove 301 on the side wall of the storage frame 3 through the slide rod 1203 and the slider 1204. Therefore, when the screw 12 rotates a certain distance, it can drive the screw barrel 1201 to move downward a certain distance. Furthermore, the rotating shaft 401 will also drive the fourth rotating rod 19, which is equipped with a third driven bevel gear 1901, to rotate through the third driving bevel gear 403 at its bottom. The fourth rotating rod 19 will then drive the cam 18 to rotate. When the cam 18 rotates to the point where its small end contacts the pulley 1801, it will squeeze the pulley 1801 and the crank rod 17 to slide downwards and compress the second spring 1702. When the cam 18 rotates to the point where its large end contacts the pulley 1801, the second spring 1702 will be released from its force and drive the crank rod 17 to move upwards and reset. Therefore, the crank rod 17 can be driven to move up and down reciprocally, and when the wire rope 6 is wound up, it can pull the wire rope 6 back and forth, so that the wire rope 6 can be evenly wound on the drum 5. This not only prevents the wire rope 6 from collapsing at one position on the drum 5, but also increases the winding amount of the drum 5.
