Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to a marine buoy placing device. Background Art

[0002] As human beings continue to explore and develop the ocean, ocean buoys can collect and transmit various precious data such as water temperature, salinity, ocean currents, and weather in real time, providing solid data support for many activities such as marine scientific research, marine environmental monitoring, fishery production, maritime shipping, and marine resource development. The operating conditions at sea are often poor, and buoys are very dangerous when deployed. It is easy for equipment to collide with the stern, operators, etc., affecting its connection effect.

[0003] The existing sea sample buoy deployment device lifts it through the mobile arm on the ship and then drops it onto the sea surface. The staff moves the buoy to the supporting plate, and then the supporting plate is fixedly connected to the mobile arm through cables and hooks, so that the mobile arm lifts the supporting plate and turns it to drop it onto the sea surface. The existing ocean buoy deployment device has obvious defects, poor stability, and the wind and waves at sea cause the supporting plate lifted by the mobile arm to shake violently, causing the buoy to be easily damaged by collision and unstable entering the water, affecting data collection, and weak anti-collision ability. There is no effective active anti-collision mechanism when the supporting plate is dropped close to the ship's side, and it is easy to collide with the ship's side hard, damaging the hull, the supporting plate and the buoy, bringing safety hazards, and inconvenient buffering. There is a lack of buffering structure to deal with wave impact or collision. The impact force acts directly, which is easy to damage the internal parts of the buoy. Maintenance is cumbersome, time-consuming and labor-intensive, reducing the deployment efficiency, and it is difficult to meet the needs of ocean monitoring.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention proposes an ocean buoy deploying device. The existing ocean buoy deploying devices have poor anti-collision protection effect. The present invention comprises a movable arm, the base of which is fixed on the ship, a hook is provided on one side of the movable arm, a cable is provided on one side of the hook, and one end of the cable is fixedly connected to a bearing plate. A bidirectional motor drives gears, racks and related components to achieve rapid and accurate placement of the buoy on the bearing plate and firm position limitation by the fixed plate, which not only reduces the manpower burden and improves work efficiency, but also lays a solid foundation for subsequent deployment accuracy, and effectively avoids the risk of damage and accuracy deviation caused by shaking and displacement of the buoy during transportation.

[0018] Secondly, in terms of protection close to the ship's side, it also relies on a bidirectional motor to drive a transmission system constructed of bevel gears, screws, sleeves, etc. to ensure that the buffer structure is in place in time. The elliptical rubber hemisphere works together with the buffer spring, and with the help of the ingenious magnetic structure of the magnet block, it is easy to store under normal conditions and flexibly unfold during operation to absorb the impact force of the load-bearing plate close to the ship's side and maintain a safe distance between the load-bearing plate and the ship, which greatly ensures that the buoy is accurately deployed as planned, protects the load-bearing plate and buoy in all directions, and extends the life of the equipment.

[0019] Furthermore, facing the challenge of strong winds and waves at sea, the guide structure and force-dividing structure on the four sides of the load-bearing plate provide buffering. The elastomeric composite shell and rollers of the guide structure reduce collision impact and guide the direction of movement through rolling friction. The force-dividing structure relies on the linkage mechanism after the arc plate is compressed to promote the interaction between the spring, polyurethane elastomer strip and air bag, and use elastic deformation and gas compression characteristics to build a powerful buffering system. The repeatedly used air bags further enhance the continuity of protection, protect the load-bearing plate and buoy from wave impact and hull shaking and collision, and ensure the safe, stable and efficient advancement of the buoy deployment operation.

[0020] Finally, during the buoy deployment phase, the reverse-driven bidirectional motor unlocks the fixed plate, and the servo motor in the inner cavity and the multi-stage hydraulic cylinder are combined to finely control the rotating plate, so that the buoy can be smoothly launched into the sea along the predetermined trajectory with gentle and precise movements, avoiding buoy rolling and instrument damage caused by rough deployment, ensuring that the buoy can immediately and stably start data collection, and providing solid support for tasks such as ocean monitoring.

[0033] Specifically, when in use, the operator will use a forklift or other lifting equipment to move the buoy to the supporting plate 4, and then start the bidirectional motor 10 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 in the opposite direction in the slide groove opened on the surface of the long plate 65 through the slider 63 on one side. The slider 63 drives the tension spring 64 to stretch and store force. The long plate 65 is fixedly connected to the inner cavity 11 of the supporting plate 4. The two groups of racks 62 drive the moving blocks 66 at each end to move in the groove 68 toward the middle of the supporting plate 4, and the two groups of moving blocks 66 drive the fixed plates 67 at each end to move closer to the buoy, so that the buoy is limited and fixed by the two groups of fixed plates 67, which can ensure the stability of the position of the buoy on the supporting plate 4, lay the foundation for the accuracy of subsequent deployment operations, and avoid the buoy from being damaged or affecting the deployment accuracy due to shaking or displacement during transportation to the deployment position; At the same time, the bidirectional motor 10 drives the bevel gear 1 91 at the other end to mesh and rotate with the four sets of bevel gears 2 92 on the outside, and the other end of the bidirectional motor 10 is rotatably connected with the connecting sleeve 93. The four sets of bevel gears 2 92 drive the screws 95 set on each side to be threadedly connected and moved with the sleeve 96. The sleeve 96 is slidably connected with the rod body 97 fixed on one side of the connecting sleeve 93 through the ring 98 at one end. The connecting sleeve 93 is also rotatably connected with the screw 95, and a cross shell 99 is provided at the bottom end of the bearing plate 4. A bottom block 94 is provided inside the cross shell 99. The bottom block 94 is rotatably connected with the other end of the bidirectional motor 10, and the screw 95 and the sleeve 96 move in the cross shell 99 to ensure that when the bearing plate 4 is close to the side of the ship, the buffer structure 12 can be in place in time to play a protective role, provide stable support for the subsequent buoy deployment, and avoid the collision of the bearing plate 4 with the side of the ship causing buoy deployment errors; As the four groups of sleeves 96 move toward the outer end at the same time, the sleeves 96 drive the elliptical rubber hemisphere 123 at each end to move toward the outer end. Since the elliptical rubber hemisphere 123 is fixedly connected to the elliptical rubber hemisphere 2 125, and buffer springs 124 are arranged inside the elliptical rubber hemisphere 123 and the elliptical rubber hemisphere 2 125, there are multiple groups of buffer springs 124 distributed at equal intervals. At the same time, a magnet block 121 connected to a rubber stick 122 is arranged on the side of the elliptical rubber hemisphere 123 away from the elliptical rubber hemisphere 2 125. The two adjacent groups of magnet blocks 121 are fixed by magnetic attraction of different poles, and are fixed when the elliptical rubber hemisphere 123 is not pushed outward. As the bidirectional motor 10 drives the elliptical rubber hemisphere 123 to move outward, the two adjacent groups of magnet blocks 121 are magnetically attracted and separated as they move, and the adjacent magnet blocks 121 are fixed by magnetic attraction of different poles to maintain the contraction of the buffer structure 12 under normal conditions. state, which is convenient for storage and maintenance, and can be flexibly separated when the bidirectional motor 10 is driven, ensuring that the buffer structure 12 is smoothly deployed. The elliptical rubber hemisphere 123 and the elliptical rubber hemisphere 2 125 are driven by the bidirectional motor 10 to exceed the length and width of the bearing plate 4, and the push structure 9 is deployed to push the buffer structure 12 outward to the side of the ship, so that when the bearing plate 4 is close to the side of the ship, the buffer structure 12 first contacts the ship, so that the bearing plate 4 keeps a certain distance from the side of the ship, avoiding the problem of inaccurate buoy deployment and damage. The elasticity of the elliptical rubber hemisphere and the buffering performance of the buffer spring 124 are used to effectively absorb the impact force when the bearing plate 4 is close to the side of the ship, avoiding hard collisions, ensuring that the bearing plate 4 keeps a safe distance from the ship, greatly improving the accuracy of buoy deployment, ensuring that the buoy can be deployed to the target sea area according to the predetermined plan, while protecting the bearing plate 4 and the buoy from damage, and extending the service life of the equipment; When the buoy is deployed and dropped by the mobile arm 1, since the mobile arm 1 is connected to the carrying plate 4 by the hook 2 and the cable 3, when the wind force at sea is strong, the carrying plate 4 will be separated from the ship and contact with the sea surface. The waves on the sea surface are uneven, which can easily cause the carrying plate 4 to collide with the side of the ship. Therefore, a slow-guide structure 7 and a force distribution structure 8 are arranged on the four sides of the carrying plate 4 to achieve the effect of protection and buffering the dispersed force. The fixed shell 71 arranged on the outer side of the four sides of the carrying plate 4 is made of an elastomer composite material. Receiving grooves 72 are arranged at equal intervals on the outer side of the fixed shell 71. A connecting plate 73 is arranged inside the storing groove 72. A roller 74 is rotatably connected to one side of the connecting plate 73 to reduce the impact force of the collision through rolling friction. The moving direction of the carrier plate 4 is guided to avoid direct collision, and an arc plate 87 is arranged inside the fixed shell 71. When the arc plate 87 is subjected to the extrusion force, the arc plate 87 presses the sleeve 96 and the connecting seat 1 86 and the connecting seat 2 812 which are rotatably connected on one side of the moving rod 1 85 and the moving rod 2 810, so that the connecting seat 1 86 and the connecting seat 2 812 rotate through the rotating shaft 811, and the connecting seat 1 86 and the connecting seat 2 812 squeeze the movable seat 1 84 and the movable seat 2 89 on the other end to move to both sides, so that the movable seat 1 84 and the movable seat 2 89 each drive the sliding block 1 82 and the sliding block 2 88 on one side to slide on the surface of the long rod 81 toward both ends, and at the same time, the sliding block 1 82 and the sliding block 2 88 on each side The connected spring 1 83 and spring 2 816 squeeze and store force, and the sliding block 1 82 and sliding block 2 88 squeeze and distribute force on the polyurethane elastomer strip 815 connected on each side, and the sliding block 1 82 and sliding block 2 88 drive the air bags 814 connected on both sides through the extension plate 813 to squeeze. There is two-thirds of gas inside the air bag 814, so as to buffer the impact force. One side of the air bag 814 is connected to the air pipe, and the air bag 814 is provided with a spring piece inside, so that the air bag 814 automatically returns to its original position through the spring piece when it is not squeezed, and air is taken in through the air pipe. The four sides of the bearing plate 4 are provided with a slow-guiding structure 7 and a force distribution structure 8, which provide all-round protection for the bearing plate 4 in a strong wind and wave environment at sea. When the wind causes the bearing plate 4 to shake and there is a contact with the side of the ship, the bearing plate 4 can be protected from the impact. When the sides tend to collide, the roller 74 of the buffer structure 7 can first contact the side of the ship, reduce the impact force of the collision through rolling friction, and guide the movement direction of the load-bearing plate 4 to avoid direct collision, ensuring the stable movement of the load-bearing plate 4 relative to the side of the ship. The 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 with the help of the compressibility of the internal gas. The multi-components cooperate to form an efficient buffer system, which protects the load-bearing plate 4 and the buoy in all directions, reduces the risk of damage caused by collision caused by wave impact and hull shaking, and ensures the safety and smoothness of the buoy deployment operation. The automatic return and air intake of the air bag 814 enable it to be used repeatedly to maintain stable buffering performance. When the supporting plate 4 is dropped to the fixed point, the bidirectional motor 10 is driven in reverse so that the two groups of fixed plates 67 are not fixed to the buoy, and then the servo motor 51 fixed inside the inner cavity 11 is started, 51 drives the rotating plate 52 at the output end to rotate, and at the same time drives the multi-stage hydraulic cylinder 53 inside the inner cavity 11 to drive the rotating plate 52 at the output end to be lifted up 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 supporting plate 4 falls onto the sea surface according to a predetermined trajectory for deployment.
