Description

Technical Field

[0001] This disclosure relates to a cable protection device for a ship's cabin and a vessel, belonging to the field of water operation equipment. Background Technology

[0002] In polar scientific expeditions, marine resource exploration, and deep-sea environmental monitoring, it is often necessary to collect deep-sea water samples in areas covered by thick ice. The traditional method involves creating a dedicated sampling port on the bottom of the vessel and lowering a water sampler equipped with a sampling container to the target depth via a cable. However, this technical solution has significant drawbacks in practical applications:

[0003] The water sampler's bottom opening is typically a rectangular structure with sharp corners or welded seams at its edges. During the raising and lowering of the water sampler, the cable will continuously rub against the four walls of the bottom opening, which can easily damage the cable.

[0004] Currently, to address the issue of cable scratching, existing work vessels typically install guide sheave assemblies inside the hull opening to guide and protect the cables. However, these guide sheave assemblies consist of several interconnected guide sheaves, requiring the cable to be threaded through them before installation. In actual operations, the cable is often pre-connected to the sampling container, preventing the guide sheave assemblies from being directly fitted around the cable without disassembling or manipulating it. This lack of effective cable protection fails to meet practical operational needs. Furthermore, the fixed guide sheaves at the hull opening can interfere with the deployment and retrieval of the water sampler. Summary of the Invention

[0005] This disclosure provides a cable protection device for ship cabins and a vessel.

[0006] According to one aspect of this disclosure, a ship's cabin cable guard device is provided, comprising:

[0007] A rotating bracket, which is rotatably mounted in the cabin;

[0008] At least two fixed protective components are fixedly installed on the rotating bracket, forming a cable protection channel with a notch; and

[0009] The movable protective component is rotatably mounted on the rotating bracket and can rotate between an open position and a closed position;

[0010] When the movable protective component is rotated to the closed position, it closes the gap in the cable protection channel. When the rotating bracket is rotated above the bottom opening, from a top-down angle, the fixed protective component and the movable protective component cover the edge of the bottom opening. When the movable protective component is rotated to the open position, it opens the gap in the cable protection channel.

[0011] According to one aspect of the technical solution disclosed herein, a rotating bracket is rotatably mounted on the ship's hold, serving as the mounting base and rotating component of the entire device. At least two fixed protective members are fixed to the rotating bracket, collectively forming a cable protection channel with a notch. This cable protection channel is used to accommodate the cable, providing a certain protective space for it. A movable protective member is also rotatably mounted on the rotating bracket and can rotate between an open position and a closed position. When the movable protective member rotates to the open position, the notch of the cable protection channel is opened, allowing the cable to be easily placed into or removed from the channel. When the rotating bracket rotates to above the bottom opening of the ship's hold and the movable protective member rotates to the closed position, it closes the notch of the cable protection channel, thereby completely enclosing the cable within the channel. The fixed and movable protective members can shield the edge of the bottom opening, preventing the cable from being scratched by sharp corners or welded joints, thus providing comprehensive protection for the cable. During installation, simply rotate the movable protective component to the open position to open the gap in the cable protection channel. The cable, already connected to the sampling container, can then be directly inserted into the channel. Then, rotate the movable protective component to the closed position to close the gap. No cable disassembly or complex operations are required, thus solving the problem of inconvenient cable installation in existing technologies and meeting practical operational needs. When the cable protection device is not needed or when deploying and retrieving the water sampler, the rotating bracket can be rotated to a suitable position to keep the cable protection device away from the water sampler's movement path, preventing obstruction during deployment and retrieval. This solves the problem of the guide wheel affecting water sampler operation in existing technologies.

[0012] According to at least one embodiment of the present disclosure, the ship cabin cable protection device further includes a first drive mechanism disposed in the ship cabin and pulsatorically connected to the rotating bracket, for driving the rotating bracket to rotate to above or to one side of the bottom opening.

[0013] In the technical solution of this embodiment, when it is necessary to rotate the rotating bracket, the first drive mechanism is activated and drives the rotating bracket to rotate through its own power transmission. This realizes the automatic rotation of the rotating bracket without the need for manual operation, which improves the convenience and efficiency of operation, reduces labor costs, and enables more precise control of the position of the rotating bracket, so as to better meet the needs of different working scenarios.

[0014] According to at least one embodiment of the hull-mounted cable guard device of the present disclosure, the first drive mechanism is a hydraulic cylinder, one end of which is hinged to the hull and the other end is hinged to the rotating bracket.

[0015] According to at least one embodiment of the present disclosure, the ship cabin cable guard device further includes a second drive mechanism disposed on the rotating bracket and pulsatorically connected to the movable protective member, for driving the movable protective member to rotate between an open position and a closed position.

[0016] In the technical solution of this embodiment, when it is necessary to operate the movable protective component, the second drive mechanism is activated, which transmits power to the movable protective component and drives it to rotate around its rotation axis between the open and closed positions, thereby realizing the automatic opening and closing of the movable protective component without the need for manual operation, which improves the convenience and safety of operation.

[0017] According to at least one embodiment of the hull-mounted cable guard device of the present disclosure, the second drive mechanism includes: a rotating shaft rotatably disposed on the rotating bracket and connected to the movable protective member; a gear fixedly connected to the rotating shaft and coaxially disposed; a rack movably disposed on one side of the gear and connected to the gear; and a linear drive mechanism disposed on the rotating bracket and connected to the rack for driving the rack to move along the extension direction of the rack.

[0018] In this embodiment, when the linear drive mechanism is activated, the drive rack moves along its extension direction. Since the rack meshes with the gear, the rack's movement drives the gear to rotate. The gear's rotation is then transmitted to the movable protective component via a rotating shaft, causing the movable protective component to rotate between the open and closed positions. Through the combination of the linear drive mechanism, rack, and gear, linear motion can be accurately converted into rotational motion, achieving precise control over the rotation of the movable protective component.

[0019] According to at least one embodiment of the hull cable guard device of the present disclosure, the rotating bracket is provided with a guide member, the guide member is provided with a groove adapted to the rack, the extension direction of the groove is the same as the extension direction of the rack, and the rack is slidably disposed in the groove.

[0020] In the technical solution of this embodiment, when the linear drive mechanism drives the rack to move, the rack can only move in a straight line along the extension direction of the slide groove under the constraint of the slide groove, and will not deviate or wobble.

[0021] According to at least one embodiment of the hull cable guard device of the present disclosure, the rotating bracket is provided with a support plate, and the support plate is provided with a groove; when the movable protective member is rotated to the closed position, the end of the movable protective member is supported and confined to the inside of the groove.

[0022] In the technical solution of this embodiment, the groove supports and limits the end of the movable protective component, preventing the movable protective component from shaking or shifting when subjected to external force.

[0023] According to at least one embodiment of the present disclosure, the ship cabin cable protection device further includes a limiting plate, which is fixedly disposed in the ship cabin and provided with a limiting groove; the rotating bracket is provided with a snap-fit ​​part, and when the rotating bracket rotates to above the bottom opening, the snap-fit ​​part snaps into the inner side of the limiting groove.

[0024] In the technical solution of this embodiment, when the rotating bracket rotates to the top of the hull bottom, the locking part will lock into the inner side of the limiting groove. The limiting groove plays a limiting role for the locking part, preventing the rotating bracket from rotating or shifting when subjected to external forces (such as hull swaying, cable tension, etc.).

[0025] According to at least one embodiment of the cable guard device for a ship's cabin, the fixed protective member and the movable protective member are rollers, the rollers include an axle and a wheel body disposed outside the axle, and the wheel body has an arc surface recessed in the axial direction in the middle.

[0026] In the technical solution of this embodiment, when the cable is placed in the cable protection channel, the cable will contact the arc surface of the roller. During the raising and lowering of the water sampler, relative rolling friction will occur between the cable and the roller, rather than sliding friction. This greatly reduces the friction between the cable and the protective component, reduces the wear of the cable, and extends the service life of the cable.

[0027] According to another aspect of this disclosure, a vessel is provided, including the cabin cable protection device and cabin as described in any of the foregoing.

[0028] According to another aspect of the technical solution disclosed herein, a cable protection device for the ship's hold is installed on the ship's hold. Through the coordinated work of its various components, it achieves the function of protecting the cables inside the bottom opening of the ship's hold, ensuring the smooth progress of operations involving cables, such as water intake operations.

[0043] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0044] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0046] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0047] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0048] The cable protection device for this ship compartment is mainly used in various types of vessels to protect the cables 8 inside the bottom opening 70 of the compartment 7, preventing the cables 8 from being scratched by the edge of the bottom opening 70 during operations such as the deployment and retrieval of the water sampler.

[0049] The cable protection device includes a rotating bracket 1, a fixed protective component 2, and a movable protective component 3.

[0050] The rotating bracket 1 is installed in a suitable position in the cabin 7, such as on the support structure at the bottom of the cabin 7, via rotatable connectors such as bearings, to ensure that the rotating bracket 1 can rotate freely around its rotation axis.

[0051] The fixed protective component 2 and the movable protective component 3 can be rollers, wear-resistant pads, or guide rings. In this embodiment, they are designed as rollers, each consisting of an axle and a wheel body. The axle is made of high-strength metal, and the axle of the fixed protective component 2 is rotatably mounted on the rotating bracket 1 via bearings.

[0052] At least two fixed protective components 2 are provided; this embodiment uses three as an example. The three fixed protective components 2 intersect perpendicularly in sequence, forming a U-shaped structure. A cable protection channel with a notch is formed between the fixed protective components 2. The size of the cable protection channel is designed according to the actual diameter of the cable 8 used, ensuring that the cable 8 can pass through smoothly and has a certain amount of room to move within the channel.

[0053] The axle of the movable protective component 3 is rotatably mounted on the rotating bracket 1 via a rotating shaft 51. The movable protective component 3 has an open position and a closed position. When the movable protective component 3 is in the closed position, it can just close the gap in the cable protection channel, forming a complete protective structure together with the fixed protective component 2. When the movable protective component 3 is rotated to the open position, the gap in the cable protection channel is opened, which facilitates the insertion or removal of the cable 8.

[0054] When the movable protective component 3 is in the closed position and the rotating bracket 1 is rotated above the bottom opening 70, from a top-down view, the fixed protective component 2 and the movable protective component 3 can completely cover the edge of the bottom opening 70 of the hull 7, providing comprehensive protection for the cable 8. When it is necessary to avoid the path of the water sampler during water sampler deployment or retrieval operations, the rotating bracket 1 can be rotated to one side of the bottom opening 70 of the hull 7.

[0055] Furthermore, to facilitate the automatic rotation of the rotating support 1, a first drive mechanism 4 is added to the aforementioned cable guard device for the ship's cabin. The first drive mechanism 4 is installed on a fixed structure of the ship's cabin 7, such as the bottom platform or the reinforcing beam of the side wall of the ship's cabin 7. The first drive mechanism 4 is connected to the rotating support 1 through a transmission device and is used to drive the rotating support 1 to rotate to the top or side of the bottom opening 70.

[0056] The first drive mechanism 4 can be a hydraulic cylinder. The hydraulic cylinder uses standard hydraulic components. One end of the cylinder body is hinged to the fixed structure of the cabin through a hinge seat, and one end of the piston rod is hinged to a specific position of the rotating bracket 1 through a hinge seat, such as a suitable position in the middle of the rotating bracket 1.

[0057] Understandably, the ship's hold can be equipped with a hydraulic system, such as a hydraulic pump, oil tank, control valve, and other components. The hydraulic pump draws hydraulic oil from the oil tank, and after being regulated by the control valve, delivers the high-pressure hydraulic oil to the hydraulic cylinder, pushing the piston rod to extend or retract. When the piston rod extends, it drives the rotating support 1 to rotate in one direction around its rotation axis; when the piston rod retracts, it drives the rotating support 1 to rotate in the opposite direction, thereby achieving the switching of the position of the rotating support 1 between above and to one side of the bottom opening 70.

[0058] To facilitate the automatic closing of the gap by the movable protective component 3, a second drive mechanism 5 is added to the cable protection device for the ship's cabin. The second drive mechanism 5 is mounted on the rotating bracket 1 and connected to the movable protective component 3 through a transmission component, and is used to drive the movable protective component 3 to rotate between the open position and the closed position.

[0059] For example, the second drive mechanism 5 includes a rotating shaft 51, a gear 52, a rack 53, and a linear drive mechanism 54. The rotating shaft 51 is a high-strength metal shaft, rotatably mounted on the rotating bracket 1 via bearings. The movable protective member 3 is connected to the rotating shaft 51 via a key connection or other fixing method, ensuring that the movable protective member 3 can rotate with the rotating shaft 51. The gear 52 is a steel gear, fixed to the rotating shaft 51 via a key connection, and coaxially arranged with the rotating shaft 51. The rack 53 is made of metal, its tooth profile matching that of the gear 52, movably disposed on one side of the gear 52, and meshing with the gear 52. The linear drive mechanism 54 can be an electric actuator or a hydraulic cylinder. Taking an electric actuator as an example, the base of the electric actuator is mounted on the rotating bracket 1 via a pin, and its actuator end is connected to the rack 53 via a connector. When the push rod of the electric push rod extends, it pushes the rack 53 to move along its extension direction. The movement of the rack 53 drives the gear 52 to rotate, which in turn drives the movable protective part 3 to rotate to the closed position through the rotating shaft 51. When the push rod of the electric push rod retracts, the rack 53 moves in the opposite direction, driving the movable protective part 3 to rotate to the open position.

[0060] Furthermore, a guide member 11 can be installed on the rotating bracket 1. The guide member 11 is made of metal and is fixed to the rotating bracket 1 with bolts. The guide member 11 is provided with a groove 111 that is adapted to the rack 53 and extends in the same direction. The size and shape of the groove 111 are designed according to the shape of the rack 53 to ensure that the rack 53 can slide smoothly in the groove 111. Through the guiding action of the groove 111, the rack 53 can move accurately along a straight line, ensuring the meshing accuracy between the rack 53 and the gear 52, and improving the transmission efficiency and stability.

[0061] To limit the maximum rotation angle of the movable protective component 3 and to support it in the closed position, a support plate 12 is provided on the rotating bracket 1. The support plate 12 is made of metal and is fixed to a suitable position on the rotating bracket 1 by welding or bolting. The support plate 12 is provided with a groove 121. The size and shape of the groove 121 are designed according to the shape of the end of the movable protective component 3 to ensure that when the movable protective component 3 is rotated to the closed position, its end can be just supported and confined to the inside of the groove 121, preventing the movable protective component 3 from shaking or shifting when subjected to external forces, thus enhancing the stability of the movable protective component 3 in the closed position.

[0062] Optionally, a limiting plate 6 is fixedly installed on the cabin. The limiting plate 6 is made of metal and is fixed to the side wall or bottom platform of the cabin with bolts. The limiting plate 6 is provided with a limiting groove 61. The size and shape of the limiting groove 61 are designed according to the snap-fit ​​part 13 on the rotating bracket 1. The snap-fit ​​part 13 is provided on the rotating bracket 1. The snap-fit ​​part 13 can be the end of the rod constituting the rotating bracket 1. When the rotating bracket 1 rotates to above the bottom opening 70, the snap-fit ​​part 13 is just snapped into the inner side of the limiting groove 61. The limiting groove 61 limits the snap-fit ​​part 13, preventing the rotating bracket 1 from rotating or shifting when subjected to external forces (such as hull swaying, cable 8 tension, etc.), and ensuring that the fixed protective part 2 and the movable protective part 3 can accurately cover the edge of the bottom opening 70.

[0063] For example, the wheel body of the aforementioned roller is made of wear-resistant rubber or high-strength plastic and is installed on the outer side of the axle through injection molding or vulcanization. A concave arc surface is provided in the middle of the wheel body, and the curvature of the arc surface is designed according to the shape of the cable 8 to ensure that the cable 8 fits well with the arc surface. When the cable 8 is placed in the cable protection channel, the cable 8 contacts the arc surface of the roller. During the raising and lowering of the water sampler, relative rolling friction occurs between the cable 8 and the roller, reducing friction and minimizing wear on the cable 8.

[0064] This embodiment provides a vessel that includes the aforementioned cable-stayed device for the hull and hull 7. Hull 7 adopts a common vessel hull structure and is designed according to the type and purpose of the vessel, such as the scientific equipment compartment of a research vessel.

[0065] The cable protection device for the ship's cabin is installed in a suitable location within cabin 7. The specific installation location is determined based on the layout of cabin 7 and the operational requirements of equipment such as the water sampler. For example, for a research vessel, the cable protection device can be installed at the bottom of the research equipment cabin, near the bottom opening 70 of the water sampler for deployment and retrieval, to ensure effective protection of the cable 8 during water sampling operations. During navigation and operations, the cable protection device operates in accordance with the working methods described in the preceding claims, providing reliable protection for the cable 8.
