Description

Technical Field

[0001] This invention relates to the field of buoy retrieval, and more particularly to an auxiliary device suitable for buoy retrieval. Background Technology

[0002] A buoy is a navigational aid that floats on the water's surface. Anchored in a designated location, it marks the extent of a navigational channel, indicates shoals, obstructions, or serves a specific purpose. Buoys are the most numerous and widely used type of navigational aid. They are placed in areas where it is difficult or unsuitable to establish fixed navigational aids. Their function is to mark shoals or obstacles that endanger navigational safety. Buoys equipped with lights are called light buoys, used for navigation in waters navigable day and night. Some buoys are also equipped with radar transponders, radio beacons, fog warning signals, and marine survey instruments. Buoys come in different types and specifications, depending on the area where they are deployed. Buoys can be divided into marine buoys and inland waterway buoys. The basic shapes of marine buoys include can-shaped, cone-shaped, spherical, cylindrical, and pole-shaped buoys. Due to the influence of wind, waves, and tides, the buoy body has a certain range of floating and cannot be used as a marker for determining the position of a ship. If a swivel-knot pole-shaped buoy is used, the position is accurate and it can be reset after being hit. Inland waterway buoys include drum-shaped buoys, triangular buoys, rod-shaped buoys, cross-current buoys, and left and right navigation buoys. The shape, color, top mark, and light quality (light rhythm, light color, flashing period) of the buoys are all made according to the prescribed standards and all have specific meanings.

[0003] When buoys are placed in the water, they are bound to get damaged. In order to ensure the safe navigation of ships, it is necessary for staff to retrieve damaged buoys in a timely manner for repair. Some severely damaged buoys need to be replaced directly. However, when retrieving buoys, staff usually drive a work boat to the vicinity of the buoy and then use a crane and ropes to retrieve the buoy from the water to the boat. However, the hooks on the telescopic buoys are not easy to hook onto the buoys. Staff need to go into the water to manually hook the hooks onto the buoys. It is not possible to quickly hook the buoys completely by mechanical means, which reduces work efficiency, increases the workload of staff, and does not guarantee their personal safety.

[0004] Therefore, it is necessary to provide an auxiliary device for buoy recovery to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides an auxiliary device for buoy retrieval, which solves the problem of not being able to quickly hook the buoy during buoy retrieval.

[0006] To solve the above-mentioned technical problems, the present invention provides an auxiliary device for buoy recovery, comprising:

[0007] hull;

[0008] A crane is mounted on the hull of the ship. The crane is equipped with a first lifting frame, and a second lifting frame is rotatably connected to one end of the first lifting frame. A lifting rope is provided at one end of the second lifting frame.

[0009] By adopting the above technical solution, the crane model is matched and set according to the weight of the buoy, and has sufficient traction to lift the buoy. The crane is connected to the control console, and the crane is controlled by operating the control console. The device can be extended forward through the first and second lifting frames, increasing the working range of the device. One end of the lifting rope is connected to the take-up drum on the crane. The upper part of the rope is a thicker steel wire rope, and the lower part is two slightly thinner steel wire ropes. The lifting rope has strong tensile strength and is sufficient to withstand the weight of the buoy.

[0010] A collection auxiliary device is provided on the lifting rope. The collection auxiliary device includes a collection sleeve. Grooves are provided on both sides of the bottom of the inner wall of the collection sleeve. A partition is fixedly connected between the top and bottom of the inner surface of the groove. An electromagnetic fixing structure is provided inside the groove. The electromagnetic fixing structure includes a micro drive motor and two threaded rods. One end of the output shaft of the micro drive motor is fixedly connected to a first transmission wheel. A second transmission wheel is sleeved on the surface of the threaded rod and located on one side of the partition. A moving block is threadedly connected to the surface of the threaded rod and located on one side of the partition. An electromagnetic moving plate is fixedly connected to one side of the moving block. One side of the electromagnetic moving plate penetrates the interior of the collection sleeve and extends to one side of the inner wall of the collection sleeve.

[0011] By adopting the above technical solution, the two steel wire ropes at the bottom of the lifting rope are connected to the collection sleeve by a buckle. The collection sleeve is made of lightweight alloy material and its overall volume is slightly larger than that of the buoy. It has openings at both the top and bottom, with the bottom opening having a larger diameter. Two grooves are located on the left and right sides of the bottom of the inner wall of the collection sleeve, respectively. The partition is equipped with a power supply device to provide power to the electromagnetic moving plate, so that the electromagnetic moving plate generates sufficient magnetic force to adhere to the surface of the buoy and increase the fixation of the buoy. After the electromagnetic moving plate contacts the buoy, the power supply device inside the partition is controlled to supply power to the electromagnetic moving plate, so that it generates sufficient electromagnetic force to fix the buoy. The moving block is equipped with a thread that matches the surface of the threaded rod. The movement of the moving plate drives the electromagnetic moving plate to move. The micro drive motor is a servo motor. By changing the rotation direction of its output shaft, the electromagnetic moving plate can be extended and retracted.

[0012] The clamping structure comprises two clamping structures located on both sides of the outer surface of the collecting sleeve. Each clamping structure includes two electric telescopic rods. A clamping plate is fixedly connected to one end of each electric telescopic rod and to one side of the inner wall of the collecting sleeve. A plurality of contraction grooves are provided on one side of the clamping plate, and limit grooves are connected to both sides of the inner surface of each contraction groove.

[0013] By adopting the above technical solution, the electric telescopic rod extends and retracts, driving the clamping plate to move and ultimately clamp the buoy. The extension length of the electric telescopic rod is automatically adjusted according to the size of the buoy. Through big data analysis in the control console, the extension length of the electric telescopic rod is controlled at an appropriate length, preventing excessive extension that would cause excessive force on the buoy and damage to the buoy surface. The clamping plate is an arc-shaped plate that fits the buoy body, ensuring that the two clamping plates can maintain a tight fit with the buoy.

[0014] Preferably, the shrinkage groove is provided with a contact structure, which includes two slide rods, with limit blocks sleeved on the surface of the slide rods, and a clamping block is fixedly connected between the opposite sides of the two limit blocks.

[0015] By adopting the above technical solution, the limiting block is slidably connected to the surface of the slide rod, and the buoy is made to be temporarily fixed by the force applied by the clamping block and maintain a stable state.

[0016] Preferably, a movable groove is provided on one side of the clamping block, and a positioning rod is slidably connected between the two sides of the inner surface of the movable groove.

[0017] By adopting the above technical solution, the stability of the clamping block during movement can be increased through the sliding connection between the positioning rod and the movable groove.

[0018] Preferably, a spring is fitted onto the surface of the positioning rod and onto the side of the clamping block opposite to the inner surface of the movable groove, and an anti-slip pad is provided on one side of the clamping block.

[0019] By adopting the above technical solution, the anti-slip mat is made of rubber synthetic material, and its surface is provided with multiple anti-slip teeth to increase the friction between it and the surface of the buoy, ensuring that the clamping block can always be squeezed and clamped to the buoy, and there will be no displacement or misalignment during the movement.

[0020] Preferably, adjustment blocks are fixedly connected to the top of both sides of the inner wall of the collecting sleeve, placement grooves are provided on both sides of the inner wall of the collecting sleeve and below the adjustment blocks, and fixing members are fixedly connected to both sides of the outer surface of the collecting sleeve.

[0021] By adopting the above technical solution, the adjusting blocks are located on the left and right sides of the inner wall of the collecting sleeve. One side of the adjusting block is set as a smooth inclined surface. When the collecting sleeve gradually descends, the side of the inclined surface facing the buoy begins to squeeze, causing the buoy to move slightly towards the middle of the collecting sleeve. This ensures that after the collecting sleeve completely covers the buoy, the buoy is exactly in the middle of the collecting sleeve. Two fixing parts are located on the left and right sides of the top of the outer surface of the collecting sleeve. The top of the fixing parts is equipped with a buckle, which is connected to the rope inside. The state of the buckle can be adjusted to separate the collecting sleeve from the lifting rope.

[0022] Preferably, the two ends of the threaded rod are respectively connected to the two sides of the inner surface of the groove, and one end of the threaded rod passes through one side of the partition and extends to the other side of the partition.

[0023] Preferably, the outer surface of the first drive wheel is connected to the outer surfaces of the two second drive wheels via belt drive, and one end of the electric telescopic rod passes through one side of the outer surface of the collecting sleeve and extends to one side of the inner wall of the collecting sleeve.

[0024] By adopting the above technical solution, the first drive wheel and the two second drive wheels are connected by a belt and can rotate at the same speed.

[0025] Preferably, one side of the first lifting frame is rotatably connected to the left side of the outer surface of the crane via a first hydraulic rod, and one side of the first lifting frame is rotatably connected to one side of the second lifting frame via one side of a second hydraulic rod.

[0026] By adopting the above technical solution, the first and second hydraulic rods can be extended through telescoping to reach a suitable working area, ensuring the normal progress of the recovery operation.

[0027] Preferably, the top of the fixing member is provided with a buckle, and one side of the surface of the adjusting block is provided with a positioning groove.

[0028] By adopting the above technical solution, the positioning groove is a relatively thin arc groove. Since the distance between the two positioning grooves is adapted to the size of the buoy, it can limit the buoy to a certain extent.

[0029] Preferably, a buoy is provided inside the collecting sleeve, and one side of each of the two electromagnetic moving plates is movably connected to both sides of the bottom surface of the buoy.

[0030] Compared with related technologies, the buoy recovery auxiliary device provided by the present invention has the following advantages:

[0031] This invention provides an auxiliary device for buoy retrieval. By replacing the traditional hook with a collection sleeve, the contact range between the collection sleeve and the buoy is increased. When locking the buoy, the collection sleeve is easier to attach to the buoy because its volume is larger than that of the buoy, thus solving the problem that traditional hooks are difficult to hook onto the buoy.

[0032] By directly fitting the collection sleeve onto the top of the buoy, the entire buoy is enclosed by the collection sleeve. Activating the electric telescopic rod causes it to extend towards the buoy, moving the clamping plate so that its contact structure clamps the buoy. Activating the micro-drive motor causes it to rotate, simultaneously rotating the first transmission wheel. The rotation of the first transmission wheel drives the second transmission wheel, which in turn rotates the threaded rod. The rotation of the threaded rod then drives... The moving block moves, simultaneously driving the electromagnetic moving plates to move. After the buoy is fitted onto the collection sleeve, the two electromagnetic moving plates first contact the buoy, and then the electromagnetic moving plates are energized, causing them to generate magnetic force and attract the outer surface of the buoy's metal, thus fixing the buoy. At the same time, the two clamping plates press and fix the outer surface of the buoy. By fixing the buoy with both structures simultaneously, the collection sleeve can firmly fix the buoy, ensuring the stability between the two when the buoy is lifted and retrieved.

[0033] By setting an adjustment block, when the collecting sleeve gradually descends and fits onto the buoy, one side of the adjustment block begins to squeeze the buoy, causing the buoy to begin to move slightly to one side, ensuring that the buoy can be in the middle position inside the collecting sleeve. This allows the electromagnetic fixing structure and the clamping structure to effectively fix the buoy and play a fine-tuning role for the buoy. Attached Figure Description

One side of the electromagnetic moving plate 646 penetrates the interior of the collection sleeve 61 and extends to one side of the inner wall of the collection sleeve 61.

[0046] The clamping structure 65 has two clamping structures 65 located on both sides of the outer surface of the collecting sleeve 61. The clamping structure 65 includes two electric telescopic rods 651. One end of the electric telescopic rod 651 and one side of the inner wall of the collecting sleeve 61 is fixedly connected to a clamping plate 652. A plurality of shrinkage grooves 653 are opened on one side of the clamping plate 652. Both sides of the inner surface of the shrinkage groove 653 are connected to the limit groove 654.

[0047] The shrinkage groove 653 has a contact structure 655 inside. The contact structure 655 includes two slide rods 6551. Limiting blocks 6552 are sleeved on the surface of the slide rods 6551. A clamping block 6553 is fixedly connected between the opposite sides of the two limiting blocks 6552.

[0048] A movable groove 6554 is provided on one side of the clamping block 6553, and a positioning rod 6555 is slidably connected between the two sides of the inner surface of the movable groove 6554.

[0049] A spring 6556 is fitted onto the surface of the positioning rod 6555, on one side of the clamping block 6553, opposite to the inner surface of the movable groove 6554. An anti-slip pad 6557 is provided on one side of the clamping block 6553.

[0050] Adjustment blocks 66 are fixedly connected to the top of both sides of the inner wall of the collecting sleeve 61. Placement slots 67 are provided on both sides of the inner wall of the collecting sleeve 61 and below the adjustment blocks 66. Fixing members 68 are fixedly connected to both sides of the outer surface of the collecting sleeve 61.

[0051] The two ends of the threaded rod 642 are respectively connected to the two sides of the inner surface of the groove 62, and one end of the threaded rod 642 passes through one side of the partition 63 and extends to the other side of the partition 63.

[0052] The outer surface of the first drive wheel 643 is connected to the outer surfaces of the two second drive wheels 644 via belt drive. One end of the electric telescopic rod 651 passes through one side of the outer surface of the collecting sleeve 61 and extends to one side of the inner wall of the collecting sleeve 61.

[0053] One side of the first lifting frame 3 is rotatably connected to the left side of the outer surface of the crane 2 via the first hydraulic rod 7, and one side of the first lifting frame 3 is rotatably connected to one side of the second lifting frame 4 via the second hydraulic rod 8.

[0054] The top of the fastener 68 is provided with a buckle, and one side of the surface of the adjusting block 66 is provided with a locking groove.

[0055] The inside of the collecting sleeve 61 is equipped with a buoy 9, and one side of each of the two electromagnetic moving plates 646 is movably connected to the two sides of the bottom surface of the buoy 9.

[0056] The working principle of the buoy recovery auxiliary device provided by this invention is as follows:

[0057] During the recovery operation, the first hydraulic rod 7 and the second hydraulic rod 8 are controlled to extend the first lifting frame 3 and the second lifting frame 4 to the location of the buoy. Then, the crane 2 is controlled to extend the rope, which moves the collection auxiliary device 6 above the buoy 9. The rope is then gradually lowered so that the collection sleeve 61 is gradually fitted onto the buoy 9. The collection sleeve 61 gradually descends and covers the buoy 9. When the adjusting block 66 contacts one side of the buoy 9, as the collection sleeve 61 gradually moves down, the inclined surface on one side of the adjusting block 66 begins to squeeze one side of the buoy 9, causing the buoy 9 to slowly move towards the middle of the collection sleeve 61. When the collection sleeve 61 completely covers the part of the buoy 9 exposed on the water surface, both sides of the buoy 9 are also locked into the locking groove on one side of the adjusting block 66.

[0058] Then, the buoy is fixed by simultaneously activating the micro drive motor 641 and the electric telescopic rod 651. The telescopic end of the electric telescopic rod 651 begins to extend and retract towards one side of the inner wall of the collecting sleeve 61, while simultaneously moving the clamping plate 652, which eventually contacts the surface of the buoy 9. At this time, several clamping blocks 6553 on one side of the clamping plate 652 simultaneously contact the surface of the buoy 9 and remain tightly fitted. The squeezing force generated by the electric telescopic rod 651 enables the clamping blocks 6553 to squeeze the buoy 9, thereby fixing the surface of the buoy 9.

[0059] Simultaneously, the micro drive motor 641 rotates, causing the first transmission wheel 643 to rotate, which in turn drives the two second transmission wheels 644 to rotate, causing the two threaded rods 642 to rotate, which in turn drives the two moving blocks 645 to move, ultimately causing the electromagnetic moving plate 646 to move until the electromagnetic moving plate 646 is tightly attached to the surface of the buoy 9. Then, by controlling the switch, the electromagnetic moving plate 646 is energized, so that the two electromagnetic moving plates 646 generate sufficient magnetic force to firmly adhere to the surface of the buoy 9, further fixing the buoy 9. Then, the crane 2 and the lifting frame are controlled to pull the buoy 9 onto the ship.

[0060] Compared with related technologies, the buoy recovery auxiliary device provided by the present invention has the following advantages:

[0061] This invention provides an auxiliary device for buoy retrieval. By using a collection sleeve 61 instead of a traditional hook, the contact range between the collection sleeve 61 and the buoy 9 is increased. When locking the buoy 9, the collection sleeve 61 is larger than the buoy 9, making it easier for the collection sleeve 61 to fit onto the buoy 9, thus solving the problem that traditional hooks are difficult to hook onto the buoy 9.

[0062] By directly attaching the collection sleeve 61 to the top of the buoy 9, the entire buoy is fitted by the collection sleeve 61. Activating the electric telescopic rod 651 causes it to extend closer to the buoy 9, moving the clamping plate 652. This causes the contact structure 655 on the clamping plate 652 to contact and clamp the buoy 9. Activating the micro-drive motor 641 causes it to rotate, simultaneously rotating the first transmission wheel 643. The rotation of the first transmission wheel 643 drives the second transmission wheel 644, causing the threaded rod 642 to rotate simultaneously. The rotation of the threaded rod 642 moves the moving block 645 and the electromagnetic moving plate 646. After the buoy 9 is fitted onto the collection sleeve 61, the two electromagnetic moving plates 646 first contact the buoy. Then, energizing the electromagnetic moving plates 646 causes them to generate magnetic force, which then interacts with the buoy 9. The outer surface of the metal is adsorbed to fix the buoy 9, and at the same time, the two clamping plates 652 squeeze and fix the outer surface of the buoy 9. By fixing the buoy 9 with two structures at the same time, the collecting sleeve 61 can firmly fix the buoy 9, and ensure the stability between the two when the buoy 9 is lifted and retrieved.

[0063] By setting the adjustment block 66, when the collecting sleeve 61 gradually descends and fits onto the buoy 9, one side of the adjustment block 66 begins to squeeze the buoy 9, causing the buoy 9 to begin to move slightly to one side, ensuring that the buoy 9 can be in the middle position inside the collecting sleeve 61, so that the electromagnetic fixing structure 64 and the clamping structure 65 can effectively fix the buoy 9 and play a fine-tuning role for the buoy 9.

[0064] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
