Description

Technical Field

[0001] This invention relates to the field of underwater dredging technology, specifically to a flexible hose deployment and retraction system. Background Technology

[0002] During large-scale aquaculture, a large amount of fish excrement and other impurities accumulate under the aquaculture cages, forming a silt layer mixed with various impurities. This pollutes the aquaculture water environment and damages the quality of the farmed aquatic products, making it urgent to clean up the silt layer under the aquaculture cages.

[0003] Currently, the removal of silt layers in aquaculture is generally carried out using underwater dredging robots. One end of a flexible hose is connected to the robot, and a winch is used to deploy and retrieve the hose. This method has the following disadvantages: 1. The hose tension is provided by the winch drum. When the hose is in a wound state, the tension and lateral pressure applied by the drum exert significant pressure on the hose, especially when the hose is wound, which can easily cause damage. 2. In large-scale and deep-water aquaculture, the dredging robot needs to be equipped with a large-diameter, long-distance flexible hose. If a traditional winch is used for deploying and retrieving the hose, the tension exerted by the winch on the hose is greater than in shallow water or short-distance situations, resulting in greater pressure on the hose wound on the winch drum and making it more prone to damage. 3. In long-distance dredging, due to the length of the hose, the traditional method of deploying and retrieving the hose concentrates the force on the hose at the winch drum. This results in high lateral pressure on the hose at bends in the hose's working path, which is not conducive to the layout of the hose's working path and occupies a lot of deck space.

[0004] In summary, the traditional method of using winches for hose deployment and retrieval is prone to damaging the hoses and is not suitable for the layout of long-distance, large-diameter hoses, resulting in insufficient utilization of the workboat's deck space. Therefore, a hose deployment and retrieval system needs to be designed to solve these problems. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a hose retraction system that is applicable to the retraction and deployment of long-distance, large-diameter hoses, and effectively avoids damage to the hoses.

[0006] To achieve the above objectives, the present invention provides a hose reeling and deployment system, including a hose coiling device and a hose conduit device. The hose coiling device includes a coiling device base, a basket, a rotary drive mechanism, a rotary joint, a rotatable connecting pipe, and a discharge pipe. The basket includes a basket bottom, an inner ring baffle, and an outer ring baffle, which are coaxially arranged and respectively located on the inner and outer sides of the basket bottom. The basket is mounted on the coiling device base and is capable of rotating around its own central axis. The rotary joint is disposed on the coiling device base and located on the central axis of the coiling device base. The rotatable connecting pipe is fixedly connected to the basket, with one end extending into the basket and the other end connected to the rotary joint. The rotatable connecting pipe is capable of rotating around the central axis of the basket through the rotary joint. One end of the discharge pipe is connected to the rotary joint. The rotating drive mechanism is connected to the basket and can drive the basket to rotate. The hose conduit device includes an S-shaped guide mechanism, which includes an S-shaped guide channel and multiple first guide roller groups. The multiple first guide roller groups are spaced apart along the extension direction of the S-shaped guide channel. Each first guide roller group includes multiple first guide rollers, and a limiting space is formed between the multiple first guide rollers for the hose to pass through. The S-shaped guide channel is used for the hose to pass through, and when the hose is in the S-shaped guide channel, it passes through the first guide roller group and is supported by the first guide rollers. The S-shaped guide mechanism is located on the outside of the basket, and the upper port of the S-shaped guide channel is located above the basket and faces the inside of the basket. When the hose is retracted or extended by the retraction system, one end of the hose is connected to the end of the rotating connecting pipe located inside the basket, and the other end passes through the S-shaped guide channel of the hose conduit device.

[0007] Furthermore, the hose coiling device also includes a slewing mechanism and a slewing guide mechanism. The basket is connected to the coiling device base via the slewing mechanism located at its axis. The slewing guide mechanism includes a circular guide rail fixed on the coiling device base and a roller installed at the bottom of the basket. The circular guide rail is coaxially arranged with the basket, and the roller is installed on the circular guide rail and can roll along the circular guide rail.

[0008] Furthermore, the rotary drive mechanism of the hose coiling device includes a ring chain, a gear, and a motor. The ring chain is fixed to the periphery of the basket and is coaxially arranged with the basket. The gear meshes with the ring chain, and the motor drives the gear to rotate.

[0009] Furthermore, the first guide roller group of the S-shaped guide mechanism includes four first guide rollers respectively arranged around the S-shaped guide channel, and the four first guide rollers together form a square limiting space.

[0010] Furthermore, the S-shaped guide mechanism includes an S-shaped boom, the S-shaped guide channel is disposed in the S-shaped boom, and the first guide roller group is mounted on the S-shaped boom.

[0011] Furthermore, it also includes a hose traction device and a hose extension guide device. The hose traction device is used for the hose to pass through and can drive the hose to move along its own axial extension direction. The hose extension guide device is provided with an extension guide channel and multiple second guide roller groups. The multiple second guide roller groups are spaced apart along the extension direction of the extension guide channel. The second guide roller group includes multiple second guide rollers, and the multiple second guide rollers form a limiting space for the hose to pass through. The extension guide channel is used for the hose to pass through, and when the hose is in the extension guide channel, it passes through the second guide roller group and is supported by the second guide rollers. When the retracting system retracts or extends the hose, the hose comes out of the S-shaped guide channel and passes through the extension guide channel of the hose traction device and the hose extension guide device.

[0012] Furthermore, the hose traction device includes two ballast mechanisms arranged opposite each other, each ballast mechanism including ballast tracks and track drive components for driving the ballast tracks. There is a traction space between the ballast tracks of the two ballast mechanisms for the hose to pass through. When the hose is in the traction space, its upper and lower sides are in close contact with the two ballast tracks respectively.

[0013] Furthermore, the hose traction device also includes a traction support frame and an adjustment mechanism. Both ballast mechanisms are mounted on the traction support frame, and at least one ballast mechanism is capable of moving up and down. The adjustment mechanism is connected to the movable ballast mechanism and can drive the two ballast mechanisms to move closer or further apart.

[0014] Furthermore, the hose extension guiding device includes an extension guiding bracket, the extension guiding channel is disposed in the extension guiding bracket, and the second guide roller group is mounted on the extension guiding bracket; the second guide roller group includes four second guide rollers respectively disposed around the S-shaped guide channel, and the four second guide rollers together form a square limiting space.

[0015] Furthermore, it also includes a hose water inlet guiding device, which has an arc-shaped water inlet channel and multiple third guide roller groups. The multiple third guide roller groups are spaced apart along the extension direction of the arc-shaped water inlet channel. Each third guide roller group includes multiple third guide rollers, and the multiple third guide rollers form a limiting space for the hose to pass through. The arc-shaped water inlet channel is used for the hose to pass through, and when the hose is in the arc-shaped water inlet channel, it passes through the third guide roller group and is supported by the third guide rollers. The outlet end of the arc-shaped water inlet channel faces downward. When the hose is retracted or extended by the retraction system, the hose passes through the arc-shaped water inlet channel and enters the water.

[0016] As described above, the hose retraction system of the present invention has the following beneficial effects:

[0017] 1. By setting up a hose coiling device to retract or lower the hose, the hose is only compressed by its own weight when coiled in the basket, reducing the stress on the hose during coiling. In addition, a hose guide device is set up to guide the hose in and out of the basket, avoiding excessive bending of the hose when entering and exiting the basket. This effectively protects the hose from compression damage caused by weight and bending, thus extending the service life of the dredging hose. Furthermore, the retraction and extension process should not affect the normal discharge operation of the hose.

[0018] 2. By setting up a hose traction device and a hose extension guide device, the hose traction device provides traction force for the movement of the hose, and the hose extension guide device constrains and guides the layout path of the hose. The layout method is flexible and can effectively save layout space on the deck of the workboat. The hose traction device can be deployed at multiple points according to the actual situation, reducing the lateral pressure of the hose at the bend, thereby reducing the risk of hose damage and extending the service life of the hose.

[0019] 3. By setting up a hose water inlet guide device, the bending and stress conditions of the dredging hose when it enters the water downwards are improved, reducing the risk of hose damage and extending the service life of the hose.

[0020] 4. It has a compact structure and can be used for the deployment and retrieval of long-distance, large-diameter underwater dredging hoses, especially for dredging work on ships. Attached Figure Description

[0082] See Figures 1 to 11 This invention provides a hose coiling system, including a hose coiling device 2 and a hose conduit device 3. The hose coiling device 2 includes a coiling device base 22, a basket 23, a rotary drive mechanism 21, a rotary joint 25, a rotary connecting pipe 24, and a discharge pipe 26. The basket 23 is annular in shape, including a basket bottom 231, an inner ring baffle 232, and an outer ring baffle 233. The inner ring baffle 232 and the outer ring baffle 233 are coaxially arranged and respectively located on the inner and outer sides of the basket bottom 231. The basket 23 is used for coiling and storing hoses. Hose 1; Basket 23 is mounted on coiling device base 22 and can rotate around its own central axis. Rotary joint 25 is set on coiling device base 22 and located on the central axis of coiling device base 22. Rotary connecting pipe 24 is fixedly connected to basket 23. One end of rotating connecting pipe 24 extends into basket 23, and the other end is connected to rotary joint 25. Rotary connecting pipe 24 can rotate around the central axis of basket 23 through rotary joint 25. Discharge pipe 26 is connected to rotary joint 25 at one end and communicates with rotating connecting pipe 24 through rotary joint 25. Rotary drive mechanism 21 is connected to basket 23 and can drive basket 23 to rotate. Hose conduit device 3 includes S-shaped guide mechanism 31. S-shaped guide mechanism 31 includes S-shaped guide channel 312 and multiple first guide roller groups 313. Multiple first guide roller groups 313 are spaced apart along the extension direction of S-shaped guide channel 312. The first guide roller group 313 includes multiple first guide rollers, and the multiple first guide rollers form a limiting space for hose 1 to pass through. The S-shaped guide channel 312 is used for the passage of the hose 1. When the hose 1 is in the S-shaped guide channel 312, it passes through the first guide roller group 313 and is supported by the first guide roller. The S-shaped guide mechanism 31 is preferably vertically arranged on the outside of the basket 23. The upper port of the S-shaped guide channel 312 is located above the basket 23 and faces the inside of the basket 23. When the hose retraction system retracts or extends the hose 1, one end of the hose 1 is connected to the end of the rotating connecting pipe 24 located inside the basket 23, and the other end passes through the S-shaped guide channel 312 of the hose conduit device 3.

[0083] The hose deployment and retrieval system of the present invention can be used for deploying and retrieval of various types of hoses 1, especially for deploying and retrieval of underwater dredging or drainage hoses 1. The hose coiling device 2 is used to store or lower the hose 1, and the hose conduit device 3 is used to guide the hose 1 in and out of the basket 23, protecting the hose 1 from bending damage. In use, one end of the hose 1 is connected to the end of the rotating connecting pipe 24 located inside the basket 23, and the other end passes through the S-shaped guide channel 312 of the hose conduit device 3, and finally extends into the hand and connects to the dredging robot. The sludge water is transported to the surface through the hose 1, and discharged to a designated location on the shore or on a ship through the rotating connecting pipe 24, the rotary joint 25 and the discharge pipe 26 in the hose coiling device 2.

[0084] The working principle of the hose reel device 2 includes: (a) when the hose 1 is retracted, see Figure 5 and Figure 6 The rotary drive mechanism 21 is activated, driving the basket 23 to rotate clockwise (from a top-down perspective) around its central axis. Simultaneously, the rotating connecting pipe 24 fixed to it rotates synchronously around the rotary joint 25. Under this rotation, the hose 1 coils up inside the basket 23, filling the bottom 231 of the basket, forming the bottom layer of the coiled structure. This coiling process continues on top of the bottom layer. Each layer of the coiled structure can be coiled from the inside to the outside of the basket 23, or from the outside to the inside. During coiling, workers use pry bars or ring jigs to assist in controlling the position of the hose 1, ensuring that it coils up sequentially. The coiling order of the hose 1 in adjacent layers is reversed; the bottom layer generally coils from the inside to the outside. (See [reference needed]). Figure 6 As shown, the next layer is coiled from the outside in, and the next layer is coiled from the inside out. This process is repeated until the hose 1 of a predetermined length is retracted into the basket 23 through the rotation of the basket 23. During the retraction of the hose 1, sewage or water can be discharged normally through the hose 1, the rotating connecting pipe 24 and the discharge pipe 26 without affecting normal operation. (b) When the hose 1 is lowered, it is pulled underwater, and the hose 1 in the basket 23 needs to be released. The basket 23 is driven to rotate counterclockwise (from a top view) around its own axis by the rotary drive mechanism 21. The rotation speed of the basket 23 can be adjusted according to the actual situation. The hose 1 is released inward from the predetermined position of the basket 23 one turn at a time. After the uppermost coiled hose 1 is released, the lower coiled hose 1 is released. This process is repeated until the hose 1 is released to the required length for construction through the continuous rotation of the basket 23. During the lowering of the hose 1, sewage or water can be discharged normally through the hose 1, the rotating connecting pipe 24 and the discharge pipe 26 without affecting normal operation.

[0085] The working principle of the hose conduit device 3 is as follows: the hose 1 in the basket 23 enters from the upper port of the S-shaped guide channel 312 and passes through the S-shaped guide channel 312, while passing through the first guide roller group 313 and being supported by the first guide roller. The hose 1 exits from the lower port of the S-shaped guide channel 312, which is close to the ground. The specific height position can be set as needed. The bending radius of the S-shaped guide channel 312 is designed to be greater than or equal to the minimum bending radius requirement of the hose 1, which can effectively improve the stress condition of the dredging hose 1 during operation and avoid excessive bending and damage to the hose 1. At the same time, during the extension and retraction process, the hose 1 is supported and guided by the first guide roller group 313 as it moves in the S-shaped guide channel 312. Through the rolling of the first guide roller, the friction of the hose 1 during the movement is reduced, thus reducing wear problems.

[0086] In the hose retraction and deployment system of the present invention, the hose 1 is retracted or lowered by setting the hose coiling device 2. When the hose 1 is wound in the basket 23, it is only squeezed by its own weight, which reduces the force on the hose 1 when wound. In addition, the hose guide device 3 is set to guide the hose 1 in and out of the basket 23, so as to avoid excessive bending of the hose 1 when entering and exiting the basket 23. This effectively protects the hose 1 from squeezing damage caused by weight and bending, and makes the service life of the dredging hose 1 longer.

[0087] See Figures 1 to 11 The present invention will be further described below with reference to a preferred embodiment:

[0088] In this embodiment, see Figure 1 , Figure 5 and Figure 6 As a preferred design, the basket 23 of the hose reeling device 2 is connected to the reeling device base 22 via a rotating mechanism 27 located at its axis. The rotating mechanism 27 includes an inner ring and an outer ring coaxially arranged and rotatable relative to each other. The basket 23 is fixedly connected to the outer ring of the rotating mechanism 27 by a pin, and the inner ring of the rotating mechanism 27 is fixedly connected to the reeling device base 22 by bolts or other means. In other embodiments, the basket 23 can also be mounted on the reeling device base 22 in other suitable ways.

[0089] In this embodiment, the rotary joint 25 also includes an inner ring and an outer ring that are coaxially arranged and rotatable relative to each other. The inner ring of the rotary joint 25 is fixedly connected to one end of the rotary connecting pipe 24, and the rotary connecting pipe 24 is fixedly connected to the bottom of the basket 23. The outer ring of the rotary joint 25 is fixed to the inner ring of the rotary mechanism 27 by bolts, and remains coaxial. The port of the discharge pipe 26 can be fixedly connected to the lower end of the inner ring of the rotary mechanism 27, thereby indirectly connecting to the outer ring of the rotary joint 25. The sludge in the rotary connecting pipe 24 can enter the discharge pipe 26 through the rotary joint 25 and finally be discharged onto the mud barge.

[0090] In this embodiment, see Figure 1 , Figure 5 and Figure 6 As a preferred design, the hose reel device 2 also includes a circular guide rail 28 fixed on the reel device base 22 and rollers 29 mounted on the bottom of the basket 23. The circular guide rail 28 is coaxially arranged with the basket 23, and the rollers 29 are mounted on the circular guide rail 28 and can roll along the circular guide rail 28. When the basket 23 rotates, the rollers 29 roll along the circular guide rail 28, serving to guide and ensure the smooth rotation of the basket 23.

[0091] In this embodiment, see Figure 1 , Figure 5 and Figure 6 As a preferred design, the rotary drive mechanism 21 of the hose reel device 2 includes an annular chain 213, a gear 211, and a motor 212. The annular chain 213 is fixed to the periphery of the basket 23 and coaxially arranged with the basket 23. The gear 211 is meshed with the annular chain 213, and the motor 212 drives the gear 211 to rotate. Preferably, multiple gears 211 are arranged next to the basket 23, and the multiple gears 211 are evenly distributed along the circumference of the basket 23. Each gear 211 is driven by a motor 212, and all motors 212 rotate synchronously. Through the rotation of the motor 212 and the gear 211, the gear 211 drives the annular chain 213 to rotate, thereby driving the basket 23 to rotate. In other embodiments, the rotary drive mechanism 21 can also adopt other suitable mechanisms.

[0092] In this embodiment, see Figure 1 and Figure 7 As a preferred design, in the S-shaped guide mechanism 31 of the hose conduit device 3, the first guide roller group 313 includes four first guide rollers respectively arranged around the S-shaped guide channel 312, and the four first guide rollers together form a square limiting space. When the hose 1 passes through the first guide roller group 313, it contacts all four first guide rollers, restricting the position of the hose 1 in four directions. Furthermore, the axes of the first guide rollers at the contact points with the hose 1 are perpendicular, thereby effectively stabilizing the position of the hose 1. When multiple first guide roller groups 313 are spaced apart along the extension direction of the S-shaped guide channel 312, the spacing between two adjacent first guide roller groups 313 can be set as needed. The number of first guide rollers in the first guide roller group 313 can also be two or three. When there are two first guide rollers, they form a V-shape, in which case both first guide rollers support the hose 1 and restrict its lateral position. When there are three first guide rollers, they form a U-shape, in which case the bottom first guide roller supports the hose 1 and restricts the lateral position of the hose 1 through the first guide rollers on both sides.

[0093] In this embodiment, see Figure 1 and Figure 7 As a preferred design, the S-shaped guide mechanism 31 includes an S-shaped boom 311, which is a truss structure with good structural strength. An S-shaped guide channel 312 is disposed within the S-shaped boom 311, and a first guide roller assembly 313 is mounted on the S-shaped boom 311. The S-shaped boom 311 supports the flexible hose 1. Further, the S-shaped guide mechanism 31 also includes a flared structure 314 disposed at the upper end of the S-shaped guide channel 312. The flared structure is a welded steel structure welded to the S-shaped boom 311. The flared structure 314 guides the flexible hose 1 into the S-shaped guide channel 312, and a first guide roller assembly 313 is also disposed at the entrance of the flared structure. The limiting space in the middle of the first guide roller assembly 313 here is larger than the limiting space of the first guide roller assembly 313 in the S-shaped guide channel 312. Preferably, the upper opening of the S-shaped guide channel 312 is located inside the outer ring baffle 233 of the basket 23 and faces downwards, so that the hose 1 can enter the S-shaped guide channel 312 from the basket 23 upwards.

[0094] In this embodiment, see Figure 1 and Figure 7 As a preferred design, the S-shaped guide mechanism 31 is fixedly mounted on a frame 32 via an S-shaped boom 311. The frame 32 is fixedly placed on the ground. A first flange 33 is welded to the upper end of the frame 32, and a second flange 34 is welded to the periphery of the S-shaped boom 311. The second flange 34 has an opening in the middle to provide a passage for the dredging hose 1. The second flange 34 is fixedly connected to the first flange 33 with bolts, thereby realizing the installation of the S-shaped guide mechanism 31.

[0095] In this embodiment, see Figure 1 , Figure 8 and Figure 10As a preferred design, the hose reeling system also includes a hose traction device 4 and a hose extension guide device 5. The hose traction device 4 is used for the hose 1 to pass through and can drive the hose 1 to move along its own axial extension direction. The hose extension guide device 5 is provided with an extension guide channel 52 and multiple second guide roller groups 53. The multiple second guide roller groups 53 are spaced apart along the extension direction of the extension guide channel 52. The second guide roller groups 53 include multiple second guide rollers, and the multiple second guide rollers form a limiting space for the hose 1 to pass through. The extension guide channel 52 is used for the hose 1 to pass through, and when the hose 1 is in the extension guide channel 52, it passes through the second guide roller groups 53 and is supported by the second guide rollers. When the hose reeling system reels in and releases the hose 1, the hose 1, after exiting the S-shaped guide channel 312, passes through the extension guide channel 52 of the hose traction device 4 and the hose extension guide device 5. The hose traction device 4 provides a certain driving force for the reeling in and releasing of the hose 1, while the hose extension guide device 5 constrains the path of the hose 1 and supports the hose 1 through the second guide rollers, reducing the friction during its movement. Depending on the arrangement of the hose 1, the extension guide channel 52 can be extended in a straight line or a curve. The hose conduit device 3 is preferably set at multiple points, with hose traction devices 4 provided on both sides of the hose extension guide device 5. After the hose 1 comes out of the hose conduit device 3, it passes through a hose traction device 4 and enters the hose extension guide device 5, and then passes through another hose traction device 4 after coming out.

[0096] In this embodiment, see Figure 1 , Figure 8 and Figure 9 As a preferred design, the hose traction device 4 includes two ballast mechanisms 41 arranged opposite each other. Each ballast mechanism 41 includes ballast tracks 411 and a track drive assembly 412 for driving the ballast tracks 411. A traction space 42 for the hose 1 to pass through is provided between the ballast tracks 411 of the two ballast mechanisms 41. The opposite sides of the two ballast tracks 411 are parallel to each other. When the hose 1 is located in the traction space 42, its upper and lower sides are in close contact with the two ballast tracks 411 respectively, and there is appropriate pressure between the hose 1 and the ballast tracks 411. The section of the hose 1 located in the traction space 42 extends in a straight line. The ballast mechanism 41 drives the hose 1 to move through the ballast tracks 411, thus achieving a traction effect. Preferably, the surface of the ballast track 411 that contacts the hose 1 is V-shaped for better contact with the hose 1.

[0097] In this embodiment, see Figure 1 , Figure 8 and Figure 9Furthermore, the hose traction device 4 also includes a traction support frame 44 and an adjustment mechanism. The traction support frame 44 is vertically fixed on a traction base 43. Two ballast mechanisms 41 are mounted on the traction support frame 44, and at least one ballast mechanism 41 can move vertically. Specifically, the upper ballast mechanism 41 is mounted on a sliding sleeve 45, which is fitted onto the traction support frame 44 and can move vertically. The adjustment mechanism includes a telescopic power cylinder 46, which can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The piston rod of the telescopic power cylinder 46 is connected to the upper ballast mechanism 41. When the piston rod moves telescopically, it can drive the upper ballast mechanism 41 to move, approaching or separating from the lower ballast mechanism 41. The lower ballast mechanism 41 can also be configured to move vertically.

[0098] In this embodiment, see Figure 1 , Figure 8 and Figure 9 Furthermore, the hose traction device 4 is provided with bottom rollers 47 on both sides of the inlet and outlet of the traction space 42 to support the hose 1. At the same time, side limiting rollers 48 are provided on both ends of the bottom rollers 47 to limit the position of the hose 1 in the direction of the two ends.

[0099] In this embodiment, see Figure 1 and Figure 10 As a preferred design, the hose extension guide device 5 includes an extension guide bracket 51, an extension guide channel 52 disposed in the extension guide bracket 51, and a third guide roller group 63 mounted on the extension guide bracket 51. The extension guide bracket 51 is a truss structure with good structural strength and is used to support the hose 1. A guide device base 54 is fixedly connected to the bottom of the extension guide bracket 51, and the hose is fixedly placed on the ground by the guide device base 54.

[0100] In this embodiment, see Figure 1 and Figure 10 The second guide roller group 53 includes four second guide rollers respectively disposed around the extended guide channel 52, and the four second guide rollers together form a square limiting space. When the hose 1 passes through the second guide roller group 53, it contacts all four second guide rollers, restricting the position of the hose 1 in four directions. Furthermore, the central axis of the contact point between the second guide roller and the hose 1 is perpendicular, thereby effectively stabilizing the position of the hose 1. When multiple second guide roller groups 53 are spaced apart along the extension direction of the extended guide channel 52, the spacing between two adjacent second guide roller groups 53 can be set as needed. The number of second guide rollers in the second guide roller group 53 can also be two or three. When there are two second guide rollers, they form a V-shape, and both second guide rollers serve to support the hose 1 and restrict the position of its two sides. When there are three second guide rollers, they form a U-shape, with the bottom second guide roller supporting the hose 1 and restricting the position of the second guide rollers on both sides.

[0101] In this embodiment, see Figure 1 and Figure 11 The hose deployment and retraction system also includes a hose water entry guide device 6. The hose water entry guide device 6 includes an arc-shaped support 61 with an arc-shaped water entry channel 62 and multiple third guide roller groups 63. These third guide roller groups 63 are spaced apart along the extension direction of the arc-shaped water entry channel 62. Each third guide roller group 63 includes multiple third guide rollers, and a limiting space is formed between them for the hose 1 to pass through. The arc-shaped water entry channel 62 allows the hose 1 to pass through. When the hose 1 is in the arc-shaped water entry channel 62, it passes through the third guide roller groups 63 and is supported by the third guide rollers. The outlet end of the arc-shaped water entry channel 62 faces downwards. After passing through the arc-shaped water entry channel 62, the hose 1 enters the water. The hose water entry guide device 6 is used to change the direction of the hose 1, guiding it to bend downwards and enter the water. The bending radius of the arc-shaped water entry channel 62 is preferably greater than the minimum bending radius of the hose 1. The arc-shaped support 61 is a truss structure with good structural strength, used to support the hose 1. The lower side of the arc-shaped bracket 61 is fixedly connected to the water inlet guide base 64, and the bracket is fixedly placed on the ground by the water inlet guide base 64.

[0102] In this embodiment, see Figure 1 and Figure 11 The third guide roller group 63 includes four third guide rollers respectively arranged around the arc-shaped water inlet channel 62, and the four third guide rollers together form a square limiting space. When the hose 1 passes through the third guide roller group 63, it contacts all four third guide rollers, restricting the position of the hose 1. The central axis of the contact point between the third guide roller and the hose 1 is perpendicular, thus effectively stabilizing the position of the hose 1. When multiple third guide roller groups 63 are spaced apart along the extension direction of the arc-shaped water inlet channel 62, the spacing between two adjacent third guide roller groups 63 can be set as needed. The number of third guide rollers in the third guide roller group 63 can also be two or three. When there are two third guide rollers, they form a V-shape, and both third guide rollers support the hose 1 and restrict the position of its two sides. When there are three third guide rollers, they form a U-shape, with the bottom third guide roller supporting the hose 1 and restricting the position of its two sides through the third guide rollers on both sides.

[0103] As can be seen from the above, the hose retraction system of the present invention has the following beneficial effects:

[0104] 1. The hose 1 is retracted or lowered by setting up a hose coiling device 2. When the hose 1 is coiled in the basket 23, it is only squeezed by its own weight, which reduces the force on the hose 1 when coiled. In addition, the hose guide device 3 is set up to guide the hose 1 in and out of the basket 23, so as to avoid excessive bending of the hose 1 when entering and exiting the basket 23. This effectively protects the hose 1 from squeezing damage caused by weight and bending, and makes the service life of the dredging hose 1 longer. Furthermore, the normal discharge operation of the hose should not be affected during the retraction and extension process.

[0105] 2. By setting up a hose traction device 4 and a hose extension guide device 5, the hose traction device 4 provides traction force for the movement of the hose 1, and the hose extension guide device 5 constrains and guides the layout path of the hose 1. The layout method is flexible and can effectively save layout space on the deck of the work boat. The hose traction device 4 can be arranged at multiple points according to the actual situation, reducing the lateral pressure of the hose at the bend, thereby reducing the risk of damage to the hose 1 and extending the service life of the hose 1.

[0106] 3. By setting up a hose water inlet guide device 6, the bending and stress conditions of the dredging hose 1 when it enters the water downwards are improved, reducing the risk of damage to the hose 1 and extending the service life of the hose 1.

[0107] 4. The structure is compact and can be used for the deployment and retrieval of long-distance, large-diameter underwater dredging hoses 1, which are especially suitable for dredging work on ships.

[0108] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0109] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
