Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to an intelligent anchoring and positioning device for marine engineering vessels. Background Technology

[0002] Intelligent anchoring and positioning devices for offshore vessels are key equipment serving the marine engineering and shipbuilding fields. They can be defined as systems that achieve precise anchoring and positioning control of vessels during offshore operations through intelligent control and coordinated mechanical structure. Specifically, these devices typically consist of an anchor winch, anchor chain, anchorage, and an intelligent control system. The anchor chain is used to lower the anchorage into the seabed, utilizing the friction between the anchorage and the seabed to fix the vessel's position. Intelligent algorithms adjust the anchor chain tension and anchoring position in real time to adapt to changes in the marine environment.

[0003] Existing ship anchoring devices have significant shortcomings in practical applications. These devices are typically installed in fixed positions on the hull, the layout of the anchor winch and anchor chain lacks flexibility, and the anchor chain guiding mechanism lacks an adjustable design. This makes it impossible to flexibly adjust the anchor chain casting angle and the expected anchoring point position based on factors such as seabed topography and current direction before anchoring. Therefore, an intelligent anchoring and positioning device for offshore vessels is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an intelligent anchoring and positioning device for marine engineering vessels to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an intelligent anchoring and positioning device for offshore vessels, comprising a support frame and a platform fixedly installed on the hull. A rotating platform is rotatably connected to the top surface of the support frame via bearings. A gear sleeve is fixedly connected to the bottom end of the rotating platform. A motor is fixedly installed at the bottom of the support frame via a bracket. A gear is fixedly connected to the output end of the motor, and the gear meshes with the gear sleeve. An anchor winch body is fixedly installed on the top surface of the rotating platform. A steel cable is fixedly connected inside the winding section of the anchor winch body, and the end of the steel cable away from the anchor winch body is fixedly connected to… An anchor is attached. A support plate is fixedly connected to the top surface of the rotating platform. A connecting frame is fixedly connected to the top surface of the support plate. The steel cable is located on the inner wall of the connecting frame. An arc-shaped limiting plate is fixedly connected to the top surface of the pad. The bottom surface of the connecting frame is in contact with the top surface of the arc-shaped limiting plate. An arc-shaped locking plate is fixedly connected to the top surface of the arc-shaped limiting plate. The top surface of the connecting frame is in contact with the bottom surface of the arc-shaped locking plate. An L-shaped locking frame is fixedly connected to the top surface of the arc-shaped locking plate. A first locking bolt is rotatably connected to the top of the L-shaped locking frame. The threaded part of the first locking bolt is threadedly connected to the arc-shaped locking plate.

[0007] Preferably, in any of the above solutions, the end of the connecting frame away from the support plate is fixedly connected to two symmetrically arranged fixed pulleys, and the steel cable is located between the two fixed pulleys.

[0008] Preferably, one side of the support plate has a through hole, and the steel cable is located inside the through hole.

[0009] Preferably, the top surface of the arc-shaped locking plate is provided with a plurality of first threaded holes arranged in a circular array, and the screw portion of the first locking bolt is threadedly connected to the arc-shaped locking plate through the first threaded holes.

[0010] Preferably, in any of the above solutions, a pin is fixedly connected to the bottom surface of the connecting frame, and an arc-shaped groove is provided on the top surface of the arc-shaped limiting plate. The pin is slidably connected to the arc-shaped limiting plate through the arc-shaped groove.

[0011] Preferably, in any of the above solutions, the support plate has two symmetrically arranged reinforcing ribs fixedly connected to the side away from the connecting frame, the through hole is located between the two reinforcing ribs, and the bottom of both reinforcing ribs is fixedly connected to the rotating table.

[0012] Preferably, one side of the rotating platform is rotatably connected to two symmetrically arranged second locking bolts, and the top surface of the support frame is provided with a plurality of circumferentially arrayed second threaded holes, and the screw portion of the second locking bolt is threadedly connected to the support frame through the second threaded holes.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the issues of fixed installation positions and difficulty in adjusting anchoring angles in traditional anchoring devices, this device utilizes a rotating platform on the support frame to achieve horizontal rotation of the anchor winch body. A motor drives gears and gear sleeves to rotate the platform, allowing for flexible adjustment of the cable's casting direction based on seabed topography, current direction, and other factors. The connecting frame slides within an arc-shaped groove via a pin, and with the guidance and locking of arc-shaped limiting and locking plates, precise adjustment of the cable casting angle is further achieved. Before anchoring, operators can first adjust the anchor winch body's orientation using the rotating platform, and then adjust the angle of the connecting frame to accurately cast the anchor to the appropriate position, avoiding anchoring position deviations caused by fixed installations and improving anchoring efficiency and stability.

[0015] 2. The fixed pulleys in the device are symmetrically arranged at the end of the connecting frame to guide and tension the steel cable, reducing friction and swaying during cable deployment and retraction. The through holes on the support plate, in conjunction with the reinforcing ribs, enhance the stability of the cable guiding structure and prevent cable deviation under stress. The arc-shaped limiting plate and arc-shaped locking plate are fixed by the L-shaped locking bracket and the first locking bolt, forming a limiting structure for the connecting frame, ensuring a stable guiding path for the steel cable during anchoring and retraction. When the cable launching angle needs adjustment, the first locking bolt is loosened, the connecting frame is rotated to the appropriate position, and then locked again. This adjustable guiding structure can adapt to different anchoring requirements and maintain cable stability during anchoring, improving the reliability and safety of the device.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 5 As shown, an intelligent anchoring and positioning device for offshore vessels includes a support frame 1 and a platform 2 fixedly installed on the hull. A rotating platform 3 is rotatably connected to the top surface of the support frame 1 via bearings. A gear sleeve 4 is fixedly connected to the bottom end of the rotating platform 3. A motor 5 is fixedly installed at the bottom of the support frame 1 via a bracket. A gear 6 is fixedly connected to the output end of the motor 5, and the gear 6 meshes with the gear sleeve 4. Anchor winch body 7 is fixedly installed on the top surface of the rotating platform 3. A steel cable 8 is fixedly connected inside the winding section of the anchor winch body 7. An anchor 9 is fixedly connected to the end of the steel cable 8 away from the anchor winch body 7. The top surface of the rotating platform 3 is fixedly connected to... A support plate 10 is provided, and a connecting frame 11 is fixedly connected to the top surface of the support plate 10. A steel cable 8 is located on the inner wall of the connecting frame 11. An arc-shaped limiting plate 12 is fixedly connected to the top surface of the pad 2. The bottom surface of the connecting frame 11 is in contact with the top surface of the arc-shaped limiting plate 12. An arc-shaped locking plate 13 is fixedly connected to the top surface of the arc-shaped limiting plate 12. The top surface of the connecting frame 11 is in contact with the bottom surface of the arc-shaped locking plate 13. An L-shaped locking frame 14 is fixedly connected to the top surface of the arc-shaped locking plate 13. A first locking bolt 15 is rotatably connected to the top of the L-shaped locking frame 14. The screw part of the first locking bolt 15 is threadedly connected to the arc-shaped locking plate 13.

[0024] As an optional technical solution of this utility model, two symmetrically arranged fixed pulleys 16 are fixedly connected to the end of the connecting frame 11 away from the support plate 10. The steel cable 8 is located between the two fixed pulleys 16. By setting two symmetrical fixed pulleys 16 at the end of the connecting frame 11 away from the support plate 10, the fixed pulleys 16 can effectively guide the direction of the steel cable 8 when it passes between them, so that it maintains a stable path during the release and retrieval process, reduces frictional wear with other components, and avoids the steel cable 8 from deviating due to uneven force, thus ensuring a smoother process for the deployment and retrieval of the anchor 9.

[0025] As an optional technical solution of this utility model, a through hole 17 is provided on one side of the support plate 10, and the steel cable 8 is located inside the through hole 17. The through hole 17 on the support plate 10 provides a through channel for the steel cable 8, further constraining the position of the steel cable 8 and making it more stable during movement. This helps to prevent the steel cable 8 from swaying or twisting when anchoring or retrieving, improving the reliability and operational safety of the entire anchoring positioning device.

[0026] As an optional technical solution of this utility model, the top surface of the arc-shaped locking plate 13 is provided with a plurality of circumferentially arranged first threaded holes 18. The screw portion of the first locking bolt 15 is threadedly connected to the arc-shaped locking plate 13 through the first threaded holes 18. The circumferentially arranged first threaded holes 18 on the top surface of the arc-shaped locking plate 13 cooperate with the first locking bolt 15, so that the connecting frame 11 can be locked at different angle positions. After adjusting the angle of the connecting frame 11 according to actual needs, the operator can firmly fix the connecting frame 11 by threading the first locking bolt 15 with the corresponding first threaded holes 18, thereby achieving precise adjustment and reliable locking of the steel cable 8 launching angle.

[0027] As an optional technical solution of this utility model, a pin 19 is fixedly connected to the bottom surface of the connecting frame 11, and an arc-shaped groove 20 is opened on the top surface of the arc-shaped limiting plate 12. The pin 19 is slidably connected to the arc-shaped limiting plate 12 through the arc-shaped groove 20. The pin 19 on the bottom surface of the connecting frame 11 and the arc-shaped groove 20 on the top surface of the arc-shaped limiting plate 12 are slidably connected, which not only provides guidance for the rotation of the connecting frame 11, but also restricts its movement trajectory, ensuring that the connecting frame 11 can only rotate along the path of the arc-shaped groove 20. This structural design makes the angle adjustment of the connecting frame 11 more stable and precise, and at the same time enhances the stability of the entire guiding mechanism.

[0028] As an optional technical solution of this utility model, two symmetrically arranged reinforcing ribs 21 are fixedly connected to the side of the support plate 10 away from the connecting frame 11. A through hole 17 is located between the two reinforcing ribs 21, and the bottom of each reinforcing rib 21 is fixedly connected to the rotating platform 3. The two symmetrical reinforcing ribs 21 on one side of the support plate 10 are both fixedly connected to the rotating platform 3 at their bottoms, with the through hole 17 located between them. The reinforcing ribs 21 effectively enhance the connection strength between the support plate 10 and the rotating platform 3, improve the deformation resistance of the entire cable guide structure, and ensure that the support plate 10 remains stable even when the cable 8 is under significant stress, thereby guaranteeing the reliability and service life of the anchoring positioning device.

[0029] As an optional technical solution of this utility model, two symmetrically arranged second locking bolts 22 are rotatably connected to one side of the rotating platform 3. The top surface of the support frame 1 has a plurality of circumferentially arrayed second threaded holes 23. The threaded portion of the second locking bolts 22 is threadedly connected to the support frame 1 through the second threaded holes 23. The second locking bolts 22 on one side of the rotating platform 3 cooperate with the circumferentially arrayed second threaded holes 23 on the top surface of the support frame 1. When the rotating platform 3 is adjusted to a suitable angle, it can be firmly locked onto the support frame 1 by the second locking bolts 22. This structural design effectively prevents the rotating platform 3 from rotating unexpectedly due to external forces during anchoring, ensuring the stability of the anchor winch body 7 and improving the safety and reliability of the entire anchoring positioning device.

[0030] A smart anchoring and positioning device for offshore vessels operates on the following principle:

[0031] 1): The motor 5 drives the gear 6 to mesh with the gear sleeve 4, which in turn drives the rotating table 3 to rotate, so that the launching direction of the steel cable 8 can be flexibly adjusted according to factors such as seabed topography and water flow direction.

[0032] 2): The connecting frame 11 slides in the arc-shaped groove 20 through the pin 19, and with the guidance and locking of the arc-shaped limiting plate 12 and the arc-shaped locking plate 13, the precise adjustment of the launching angle of the steel cable 8 can be further realized.

[0033] 3) Before anchoring, the operator can first adjust the position of the anchor winch body 7 by rotating the table 3, and then use the angle adjustment of the connecting frame 11 to make the anchor 9 accurately throw to a suitable position, avoiding anchoring position deviation caused by fixed installation.

[0034] In summary, this intelligent anchoring and positioning device for offshore vessels achieves horizontal rotation of the anchor winch body 7 via a rotating platform 3 on the support frame 1. The motor 5 drives the gear 6 to mesh with the gear sleeve 4, rotating the rotating platform 3 and allowing the casting direction of the steel cable 8 to be flexibly adjusted according to factors such as seabed topography and current direction. The connecting frame 11 slides within the arc-shaped slot 20 via a pin 19, and with the guidance and locking of the arc-shaped limiting plate 12 and the arc-shaped locking plate 13, further precise adjustment of the casting angle of the steel cable 8 is achieved. Before anchoring, the operator can first adjust the orientation of the anchor winch body 7 using the rotating platform 3, and then adjust the angle of the connecting frame 11 to accurately cast the anchor 9 to a suitable position, avoiding anchoring position deviations caused by fixed installation, and improving anchoring efficiency and stability. The fixed pulleys 16 in the device are symmetrically arranged at the end of the connecting frame 11, guiding and tensioning the steel cable 8, reducing friction and swaying during the cable's deployment and retraction. The through-hole 17 on the support plate 10 cooperates with the reinforcing rib 21 to enhance the stability of the cable guide structure and prevent the cable from deviating under stress. The arc-shaped limiting plate 12 and the arc-shaped locking plate 13 are fixed by the L-shaped locking frame 14 and the first locking bolt 15 to form a limiting structure for the connecting frame 11, ensuring that the cable 8 maintains a stable guide path during anchoring and retraction. When it is necessary to adjust the cable launching angle, the first locking bolt 15 is loosened, the connecting frame 11 is rotated to the appropriate position, and then locked. This adjustable guide structure can adapt to different anchoring requirements and maintain the stability of the cable during anchoring, improving the reliability and safety of the device.
