Description

Technical Field

[0001] The present invention relates to the technical field of ocean engineering, and particularly to an ocean buoy deployment device. Background Art

[0002] With the continuous deepening of human exploration and development of the ocean, ocean buoys can collect and transmit various precious data such as water temperature, salinity, ocean current, and meteorology in real time, providing solid data support for many activities such as ocean scientific research, ocean environmental monitoring, fishery production, maritime shipping, and ocean resource development. However, the offshore operation conditions are often poor, and the deployment of buoys is extremely dangerous, prone to collisions with the stern of the ship, operators, etc., affecting their connection effect.

[0003] The existing ocean buoy deployment device hoists the buoy by a moving arm on the ship and then drops it onto the sea surface. The staff moves the buoy onto the carrier plate, and then the carrier plate is fixedly connected to the moving arm through a cable and a hook, so that the moving arm hoists the carrier plate and turns it to be dropped onto the sea surface. The existing ocean buoy deployment device has obvious defects, such as poor stability. The carrier plate hoisted by the moving arm shakes violently due to the sea waves, resulting in the buoy being easily damaged by collision and having an unstable entry attitude into the water, affecting data collection. Its anti-collision ability is weak. When the carrier plate is dropped near the ship's side, there is no effective active anti-collision mechanism, and it is easy to have a hard collision with the ship's side, damaging the ship's body, the carrier plate, and the buoy, bringing potential safety hazards. The buffering is inconvenient. There is a lack of a buffering structure to cope with the impact of sea waves or collisions, and the impact force acts directly, easily damaging the internal parts of the buoy. The maintenance is cumbersome, time-consuming, and laborious, reducing the deployment efficiency and making it difficult to meet the requirements of ocean monitoring.

[0004] In view of the above problems, an innovative design is made on the basis of the original ocean buoy deployment device. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] A marine buoy deployment device proposed by the present invention has a poor anti-collision protection effect compared to existing marine buoy deployment devices. The present invention includes a moving arm, the base of the moving arm is fixed on a ship, a hook is provided on one side of the moving arm, a cable is provided on one side of the hook, and one end of the cable is fixedly connected to a bearing plate. By driving gears, racks and related components through a bidirectional motor, the buoy can be quickly and accurately placed on the bearing plate and firmly limited by a fixing plate, which not only reduces the labor burden and improves the operation efficiency, but also lays a solid foundation for the subsequent deployment accuracy, and effectively avoids the risks of damage and accuracy deviation caused by shaking and displacement during the buoy transportation.

[0023] Secondly, in terms of the protection near the ship side, relying on the transmission system composed of a bidirectional motor driving bevel gears, screws, sleeves, etc., it ensures that the buffer structure is in place in time. The elliptical rubber hemisphere and the buffer spring cooperate, and with the help of the ingenious magnetic attraction structure of the magnet block, it is convenient for storage under normal conditions and can be flexibly deployed during operation, absorbing the impact force when the bearing plate approaches the ship side, maintaining a safe distance between the bearing plate and the ship, greatly ensuring the accurate delivery of the buoy as planned, protecting the bearing plate and the buoy in all directions, and extending the service life of the equipment.

[0024] Furthermore, in the face of the challenges of strong winds and waves at sea, the buffer and guiding structures and force-sharing structures on the four sides of the bearing plate buffer. The elastic composite material shell and rollers of the buffer and guiding structure reduce the collision impact and guide the movement direction through rolling friction. The force-sharing structure, relying on the linkage mechanism after the arc plate is pressed, promotes the interaction of springs, polyurethane elastomer strips and air bags, using the characteristics of elastic deformation and gas compression together to build a powerful buffer system. The reusable air bags further strengthen the protection sustainability, resist the impact of sea waves and the collision of the hull shaking for the bearing plate and the buoy, and escort the safe, stable and efficient progress of the buoy deployment operation.

[0025] Finally, at the stage of buoy delivery, reverse drive the bidirectional motor to unlock the fixing plate, and combine the servo motor and the multi-stage hydraulic cylinder in the inner cavity to finely control the rotating plate, so as to gently and accurately assist the buoy to smoothly enter the sea along the predetermined trajectory, avoiding problems such as buoy rolling and instrument damage caused by rough delivery, ensuring that the buoy immediately and stably starts data collection work, and providing a solid guarantee for tasks such as ocean monitoring.

One side of the moving block 66 is connected to the fixing plate 67, and the other side of the moving block 66 is connected to the rack 62. A long plate 65 is arranged inside the inner cavity 11. A sliding groove is formed on the surface of the long plate 65. A slider 63 is slidably connected inside the sliding groove. The slider 63 is connected to the rack 62. One side of the slider 63 is provided with a tension spring 64. The end of the tension spring 64 away from the slider 63 is connected to the sliding groove, which can ensure the stable position of the buoy on the bearing plate 4 and lay a foundation for the accuracy of subsequent placement operations.

[0042] The pushing structure 9 includes a bevel gear set arranged at one end of the bidirectional motor 10. A screw rod 95 is arranged outside the bevel gear set.

A connecting sleeve frame 93 is rotatably connected to the outside of the other end of the bidirectional motor 10. A bevel gear two 92 is arranged on one side of the connecting sleeve frame 93 close to the bevel gear one 91. There are four groups of bevel gear two 92, and all four groups of bevel gear two 92 are meshed with the bevel gear one 91. The screw rod 95 and the sleeve 96 are also respectively distributed in one-to-one correspondence with the four groups of bevel gear two 92. All four groups of screw rods 95 are rotatably connected to the connecting sleeve frame 93. A rod body 97 is arranged on one side of the connecting sleeve frame 93.

The buffer structure 12 can play a protective role in a timely manner and provide stable support for subsequent buoy placement.

[0043] The buffer structure 12 includes an elliptical rubber hemisphere one 123 disposed at one end of the sleeve 96. A buffer spring 124 is provided on one side of the elliptical rubber hemisphere one 123. One side of the buffer spring 124 is fixedly connected to an elliptical rubber hemisphere two 125. The buffer spring 124 is disposed inside the elliptical rubber hemisphere one 123 and the elliptical rubber hemisphere two 125. There are multiple groups of buffer springs 124 evenly distributed at equal intervals. The buffer springs 124 in the middle of the elliptical rubber hemisphere one 123 and the elliptical rubber hemisphere two 125 gradually decrease from the middle to both sides. A rubber rod 122 is provided on the side of the elliptical rubber hemisphere one 123 away from the elliptical rubber hemisphere two 125. A magnet block 121 is provided at one end of the rubber rod 122. There are four groups of the elliptical rubber hemisphere one 123 and the elliptical rubber hemisphere two 125 evenly distributed at equal intervals. The adjacent two magnet blocks 121 are fixed by attracting each other with opposite poles. The buffer structure 12 first contacts the ship, keeping the carrier plate 4 at a certain distance from the ship side, avoiding problems such as inaccurate buoy placement and damage. Utilizing the elasticity of the elliptical rubber hemisphere and the buffering performance of the buffer spring 124, the impact force when the carrier plate 4 approaches the ship side can be effectively absorbed.

[0044] The component force structure 8 includes a long rod 81 disposed inside the fixed shell 71. A slider one 82 and a slider two 88 are slidably connected to the surface of the long rod 81. The slider one 82 and the slider two 88 move in opposite directions. A spring one 83 and a spring two 816 are respectively provided on one side of the slider one 82 and the slider two 88. The spring one 83 and the spring two 816 are connected and fixed to the inner wall of the fixed shell 71 away from the slider one 82 and the slider two 88. An extension plate 813 is provided at the top of the slider one 82 and the slider two 88. An airbag 814 is provided on one side of the extension plate 813. One end of the airbag 814 is connected to the inner wall of the fixed shell 71. A polyurethane elastomer strip 815 is provided on one side of the slider one 82 and the slider two 88. One end of the polyurethane elastomer strip 815 is connected to the inner wall of the fixed shell 71. An activity seat one 84 and an activity seat two 89 are provided on the other side of the slider one 82 and the slider two 88. A moving rod one 85 and a moving rod two 810 are respectively rotatably connected to one side of the activity seat one 84 and the activity seat two 89. The moving rod one 85 and the moving rod two 810 are in a cross shape. A rotating shaft 811 is provided at the intersection of the moving rod one 85 and the moving rod two 810. The ends of the moving rod one 85 and the moving rod two 810 away from the slider one 82 and the slider two 88 are rotatably connected to a connection seat one 86 and a connection seat two 812. An arc-shaped plate 87 is provided on one side of the connection seat one 86 and the connection seat two 812. The arc-shaped plate 87 is connected to the inner wall of the fixed shell 71. It protects the carrier plate 4 and the buoy in all directions, reducing the risk of damage caused by collisions due to sea wave impacts and ship hull vibrations, and ensuring the safe and smooth progress of the buoy placement operation.

[0045] Specifically, during use, the operation will move the buoy to the bearing plate 4 with the help of a forklift or other lifting equipment. Then, the bidirectional motor 10 is started to drive. The gear 61 at one end of the bidirectional motor 10 rotates and meshes with the racks 62 on both sides. The racks 62 slide reversely through the sliders 63 on one side in the chutes opened on the surface of the long plate 65. The sliders 63 drive the tension springs 64 to stretch and store energy. The long plate 65 is fixedly connected to the inner cavity 11 of the bearing plate 4. The two racks 62 drive the moving blocks 66 at each end to move towards the middle of the bearing plate 4 in the notch 68, and the two moving blocks 66 drive the fixing plates 67 at each end to move closer to the buoy. Thus, the buoy is limited and fixed by the two fixing plates 67, which can ensure the stable position of the buoy on the bearing plate 4, lay a foundation for the accuracy of the subsequent laying operation, and avoid damage to the buoy or affect the laying accuracy due to shaking and displacement during the transportation to the throwing position;

[0046] At the same time, the bidirectional motor 10 drives the bevel gear one 91 at the other end to mesh and rotate with the four bevel gears two 92 on the outside. The other end of the bidirectional motor 10 is rotatably connected to the connecting sleeve frame 93. The four bevel gears two 92 drive the screws 95 arranged on each side to be threadedly connected and move with the sleeves 96. The sleeves 96 are slidably connected to the rod body 97 fixed on one side of the connecting sleeve frame 93 through the collar 98 at one end. The connecting sleeve frame 93 is also rotatably connected to the screws 95. And a cross shell 99 is arranged at the bottom end of the bearing plate 4. A bottom block 94 is arranged inside the cross shell 99. The bottom block 94 is rotatably connected to the other end of the bidirectional motor 10. The screws 95 and the sleeves 96 move in the cross shell 99 to ensure that when the bearing plate 4 approaches the ship side, the buffer structure 12 can be in place in time to play a protective role, provide a stable support for the subsequent buoy laying, and avoid mistakes in buoy laying caused by the collision between the bearing plate 4 and the ship side;

[0047] As the four sets of sleeves 96 move simultaneously towards the outer end, the elliptical rubber hemispheres I 123 at one end of each sleeve 96 are driven to move towards the outer end. Since the elliptical rubber hemispheres I 123 are fixedly connected to the elliptical rubber hemispheres II 125, and buffer springs 124 are arranged inside the elliptical rubber hemispheres I 123 and the elliptical rubber hemispheres II 125, with multiple groups of buffer springs 124 evenly distributed. At the same time, a magnet block 121 connected to a rubber rod 122 is arranged on the side of the elliptical rubber hemisphere I 123 away from the elliptical rubber hemisphere II 125. Adjacent two groups of magnet blocks 121 are fixed by opposite-pole magnetic attraction, and are fixed when the elliptical rubber hemisphere I 123 is not pushed outwards. As the elliptical rubber hemisphere I 123 moves outwards driven by the bidirectional motor 10, the magnetic attraction of adjacent two groups of magnet blocks 121 separates as they move, and adjacent magnet blocks 121 are fixed by opposite-pole magnetic attraction. In the normal state, the contraction state of the buffer structure 12 is maintained, which is convenient for storage and maintenance. When the bidirectional motor 10 is driven, it can be flexibly separated to ensure the smooth deployment of the buffer structure 12. The elliptical rubber hemisphere I 123 and the elliptical rubber hemisphere II 125 exceed the length and width of the bearing plate 4 driven by the bidirectional motor 10, and the pushing structure 9 is unfolded to push the buffer structure 12 towards the outer side against the ship's side. When the bearing plate 4 approaches the ship's side, the buffer structure 12 contacts the ship first, keeping a certain distance between the bearing plate 4 and the ship's side, avoiding problems such as inaccurate buoy placement and damage. Utilizing the elasticity of the elliptical rubber hemisphere and the buffering performance of the buffer spring 124, the impact force when the bearing plate 4 approaches the ship's side is effectively absorbed, avoiding hard collisions, ensuring a safe distance between the bearing plate 4 and the ship, greatly improving the accuracy of buoy placement, ensuring that the buoy can be placed in the target sea area according to the predetermined plan, and at the same time protecting the bearing plate 4 and the buoy from damage, and extending the service life of the equipment;

[0048] When the buoy is deployed by the moving arm 1, since the moving arm 1 is connected to the bearing plate 4 through the hook 2 and the cable 3, when the wind force at sea is relatively large, the bearing plate 4 will be separated from the ship and contact the sea level. The waves on the sea level are uneven, which easily causes the bearing plate 4 to collide with the side of the ship. Therefore, buffer and guiding structures 7 and force dividing structures 8 are provided on the four sides of the bearing plate 4 to achieve the effects of protection and buffer force dispersion. The fixed shell 71 provided on the outer sides of the four sides of the bearing plate 4 is made of an elastomeric composite material. Receiving grooves 72 are equidistantly opened on the outer side of the fixed shell 71. A connecting plate 73 is provided inside the receiving groove 72. One side of the connecting plate 73 is rotatably connected to a roller 74, which reduces the impact force of the collision through rolling friction and guides the moving direction of the bearing plate 4 at the same time to avoid direct impact. And an arc-shaped plate 87 is provided inside the fixed shell 71. When the arc-shaped plate 87 is subjected to an extrusion force, the arc-shaped plate 87 presses the sleeve 96, the first moving rod 85, and the connecting seats 86 and 812 rotatably connected to one side of the second moving rod 810. As a result, the connecting seats 86 and 812 rotate through the rotating shaft 811, and the connecting seats 86 and 812 squeeze the movable seats 84 and 89 at the other ends to move to both sides, so that the movable seats 84 and 89 drive the sliding blocks 82 and 88 on one side to slide towards both ends on the surface of the long rod 81. At the same time, the sliding blocks 82 and 88 squeeze and store energy in the first spring 83 and the second spring 816 connected to one side of each of them, and the sliding blocks 82 and 88 also squeeze and divide the force of the polyurethane elastomer strips 815 connected to one side of each of them. The sliding blocks 82 and 88 drive the air bags 814 connected by the extension plates 813 on both sides to be squeezed. Two-thirds of the air is inside the air bag 814, so as to buffer the impact force. One side of the air bag 814 is connected to a trachea, and elastic sheets are provided inside the air bag 814. Therefore, when the air bag 814 is not squeezed, it automatically returns to its original position through the elastic sheets and intakes air through the trachea. Buffer and guiding structures 7 and force dividing structures 8 are provided on the four sides of the bearing plate 4 to provide all-round protection for the bearing plate 4 in a rough sea environment. When the wind force causes the bearing plate 4 to shake and there is a tendency to collide with the side of the ship, the rollers 74 of the buffer and guiding structure 7 can first contact the side of the ship, reduce the impact force of the collision through rolling friction, and guide the moving direction of the bearing plate 4 at the same time to avoid direct impact, ensuring the smooth movement of the bearing plate 4 relative to the side of the ship. The second spring 816 and the polyurethane elastomer strip 815 use elastic deformation to buffer and disperse the impact force, and the air bag 814 further absorbs the impact energy by virtue of the compressibility of the internal gas. The cooperation of multiple components forms an efficient buffer system to protect the bearing plate 4 and the buoy in all directions, reduce the risk of damage caused by collisions due to wave impact and hull shaking, and ensure the safe and smooth progress of the buoy deployment operation. The automatic return and air intake of the air bag 814 enable it to be reused and maintain stable buffer performance;

[0049] After the carrier plate 4 is placed at a fixed point, reverse drive the bidirectional motor 10 so that the two sets of fixed plates 67 do not fix the buoy. Then, start the servo motor 51 fixed inside the drive cavity 11. The servo motor 51 drives the rotating plate 52 at the output end to rotate. At the same time, the multi-stage hydraulic cylinder 53 inside the drive cavity 11 drives the rotating plate 52 at the output end to lift upward at the end away from the servo motor 51. With the rotation of the rotating plate 52 and the pushing of the multi-stage hydraulic cylinder 53, the buoy on the carrier plate 4 falls onto the sea surface along a predetermined trajectory for deployment.
