Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and more specifically to a rapid deployment device and method for a rotary articulated arm marine equipment. Background Technology

[0002] Currently, various small and medium-sized marine equipment, such as underwater vehicles and buoys, are developing rapidly and are increasingly widely used in marine geological exploration, environmental monitoring, target detection, and marine search and rescue. However, the rapid and safe deployment of these devices remains a major challenge for their application at sea.

[0003] Currently, the dominant deployment method is using a shipborne crane. This method requires vessels equipped with lifting equipment such as gantry cranes, straight-arm cranes, or folding-arm cranes, and demands experienced crane operators. It imposes significant limitations on the vessel itself; vessels without cranes cannot perform deployment operations. More importantly, in rough seas, marine equipment is highly susceptible to swaying and shaking on the slings, leading to collisions or detachment. Multiple personnel are needed to stabilize the equipment using ropes and forks, requiring a large number of experienced personnel and posing significant safety risks to both personnel and equipment. Crane deployment is typically only feasible in sea states of level three and below, exhibiting poor environmental adaptability.

[0004] Besides cranes, there are also deployment methods using dedicated slipways or rails. These devices are usually customized for specific marine equipment, have poor versatility, and are generally only suitable for small vessels with very low freeboard. Furthermore, slipways and rails are installed outside the ship's side, making them difficult to secure to the hull and prone to detachment; their large size also requires a low shipboard height, further limiting the types of vessels they can be used on. Therefore, this type of method can mostly only be used in freshwater or good near-shore sea conditions, exhibiting extremely poor environmental adaptability.

[0005] In summary, existing methods for deploying small and medium-sized marine equipment generally suffer from problems such as high requirements for vessels, complex operation, high safety risks, poor environmental adaptability, and low universality. There is an urgent need for a deployment device that is more adaptable, easier to operate, and safer. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary articulated arm type rapid deployment device and method for marine equipment, in order to solve the problems of poor adaptability of existing marine equipment deployment methods to ships and equipment, high requirements for operators and sea conditions, and high safety risks caused by equipment shaking during deployment.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rotary articulated boom type rapid deployment device for marine equipment includes: A base, located on the deck along the hull's side; A rotating arm is rotatably connected to the base via a rotating component, and the rotating arm can rotate horizontally relative to the base. The swing seat has a V-shaped structure, with the front end of the rotating arm hinged at its middle position; The first telescopic cylinder has a rotating arm hinged at one end and a swing seat hinged at the other end. The folding arm, whose rear end is connected to the front end of the swing seat, is used to place marine equipment. In this configuration, one end of the first telescopic cylinder extends and retracts relative to the other end, thereby causing the folding arm to swing vertically relative to the rotating arm. A locking release device, located on the folding arm, is used to lock marine equipment onto the folding arm or to release marine equipment from the folding arm.

[0008] Furthermore, it also includes a counterweight frame, which is disposed at the rear end of the rotating arm, and the bottom of the counterweight frame is provided with load-bearing rollers, which are in rolling contact with the deck; The counterweight frame is equipped with a counterweight, which is used to balance the weight of the front end of the rotating arm and one side of the folding arm.

[0009] Furthermore, the rear end of the rotating arm is provided with a handle for the operator to manually push and pull to make the rotating arm rotate horizontally relative to the base.

[0010] Furthermore, the rotating component is configured as a slewing bearing, with the fixed end of the slewing bearing connected to the base and the rotating end of the slewing bearing connected to the rotating arm; It is also equipped with a power mechanism that drives the rotating end of the slewing bearing to rotate relative to the fixed end.

[0011] Furthermore, the folding arm is provided with several anti-slip strips, which are arranged along the extension direction of the folding arm, and at least one row of support rollers is provided on one side of the anti-slip strips on the folding arm. When the pressure applied to the marine equipment by the locking release device does not reach the set threshold, the support roller protrudes from above the anti-slip strip to roll and contact the marine equipment.

[0012] Furthermore, the folding arm is provided with a first slide rail arranged radially thereon, and a first slide block is slidably fitted on the first slide rail. The inner end of the first slide block is connected to the folding arm via an elastic element, and the outer end of the first slide block is rotatably connected to the support roller.

[0013] Furthermore, the locking release device includes a support base, a second slide rail, a second slide block, a third slide rail, a third slide block, a clamping rod, a connecting rod, a second telescopic cylinder, a gripper, and a transition rod; The support base is mounted on the folding arm. A second slide rail is provided at both the front and rear ends of the support base. The second slide rails extend along the left and right directions of the folding arm. The left and right sides of each second slide rail are slidably engaged with a second slide block. A third slide rail is provided at both the front and rear ends of the support base. The third slide rail extends along the front and rear directions of the folding arm, and a third slide block slides on each third slide rail. The two ends of the left clamping rod are connected to the second slide on the left, and the two ends of the right clamping rod are connected to the second slide on the right. One end of the connecting rod is hinged to the end of the clamping rod, and the other end of the connecting rod is hinged to the third slide on the same side; The two ends of the second telescopic cylinder are each connected to a third slide block; The lower ends of the grippers are hinged to both the left and right sides of the support base; Both the left and right clamping rods are equipped with transition rods, the ends of which are movably connected to the middle position of the gripper on the same side; The two ends of the second telescopic cylinder extend relative to each other to drive the gripper to press against the marine equipment, thereby locking the marine equipment onto the folding arm; The two ends of the second telescopic cylinder retract relative to each other to drive the gripper to detach from the marine equipment, thereby releasing the marine equipment from the folding arm.

[0014] Furthermore, the locking release device includes a support base, a geared motor assembly, and a gripper; The support base is mounted on the folding arm, the reduction motor assembly is mounted on the support base, and the output end of the reduction motor assembly is connected to the gripper. The output end of the geared motor unit rotates in the forward direction to drive the gripper to press against the marine equipment, thereby locking the marine equipment onto the folding arm. The output end of the geared motor unit rotates in the opposite direction to drive the gripper to detach from the marine equipment, thereby releasing the marine equipment from the folding arm.

[0015] Furthermore, a fourth slide rail is provided on the folding arm, which is arranged along the extension direction of the folding arm, and the support seat is slidably engaged with the fourth slide rail.

[0016] A method for rapid deployment of marine equipment, using the aforementioned rotary articulated boom type rapid deployment device for marine equipment, the method comprising the following steps: S1. Place the marine equipment to be deployed on the folding arm and lock and fix the marine equipment on the folding arm using the locking release device; S2. Drive the rotating arm to rotate relative to the base along the horizontal plane, so that the rotating arm drives the folding arm to rotate from the inside of the ship's side to the outside of the ship's side; S3. Drive the folding arm to swing vertically downward relative to the rotating arm, so that the marine equipment on the folding arm is close to the water surface or enters the water; S4. Control the locking release device to release the marine equipment from the folding arm, completing the deployment.

[0017] Compared with the prior art, the rotary folding arm marine equipment rapid deployment device and method of the present invention have achieved the following significant technical effects: 1. This invention utilizes a combined motion of horizontal rotation of the rotating arm and vertical swing of the folding arm to smoothly transfer marine equipment from the inside of the ship's hull to the outer water surface, avoiding the drawbacks of traditional crane deployment where equipment sways and shakes on the hoisting ropes. Combined with the rigid locking mechanism and the support rollers and anti-slip strips on the folding arm, the equipment remains stable and does not slip even in medium to high sea states, enabling safe operation in sea states of level four and above, significantly improving environmental adaptability.

[0018] 2. This invention adopts a base-fixed design on the deck, eliminating the need for heavy lifting equipment such as shipboard cranes, and can be installed and used on ordinary ships without cranes. Meanwhile, the adjustable boom length and adjustable locking release position along the fourth rail allow it to be adapted to various small and medium-sized marine equipment such as underwater vehicles and buoys, solving the problem that traditional slipways or rails require customization for specific equipment and are only suitable for ships with low freeboard.

[0019] 3. This invention achieves rapid transfer of equipment from the deck to the water surface through the horizontal rotation of the rotating arm and the vertical swing of the folding arm; the locking and releasing device is driven by a telescopic cylinder or motor, and the locking and releasing of marine equipment can be completed with one button. The entire deployment process does not require experienced crane operators, nor does it require multiple people to assist in stabilization with stabilizing ropes and forks. A single person can easily complete the operation, greatly reducing the requirements for the number and experience of operators.

[0020] 4. During the deployment of marine equipment, when the locking release device applies a set threshold pressure to the equipment, the support rollers retract, and the equipment directly abuts against the anti-slip strip. Combined with the clamping and locking mechanism, this forms a multi-point stable fixation, effectively preventing the equipment from falling off or colliding during transport. The counterweight frame and counterweight body balance the weight on the folding arm side, and with the support of the load-bearing rollers, ensure smooth rotation of the rotating arm, avoiding the risk of tipping over. When the equipment is about to enter the water, the locking release device releases the marine equipment from the folding arm. The locking release device does not apply pressure to the marine equipment, and the support rollers protrude from above the anti-slip strip, allowing the equipment to roll and slide down the folding arm, avoiding damage from impacts.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Example 1: In this embodiment of the invention, a rapid deployment device and method for a rotary articulated boom marine equipment are provided. Please refer to [reference needed]. Figures 1 to 9 As shown.

[0025] A rotary articulated boom marine equipment rapid deployment device includes a base 1, a rotary arm 2, a swing seat 3, a first telescopic cylinder 4, an articulated boom 5, and a locking release device 6.

[0026] The base 1 is mounted on the deck 72 along the edge of the ship's side 71. The rotating arm 2 is rotatably connected to the base 1 at its midpoint via a rotating component, allowing it to rotate horizontally relative to the base 1. The swing seat 3 has a V-shaped structure, with its midpoint hinged to the front end of the rotating arm 2. One end of the first telescopic cylinder 4 is hinged to the rotating arm 2, and the other end is hinged to the rear end of the swing seat 3. The rear end of the folding arm 5 is fixedly connected to the front end of the swing seat 3, and the folding arm 5 is used to hold marine equipment 7. One end of the first telescopic cylinder 4 extends and retracts relative to the other end, causing the folding arm 5 to swing vertically relative to the rotating arm 2. A locking release device 6 is mounted on the folding arm 5 to lock the marine equipment 7 onto the folding arm 5, or to release the marine equipment 7 from the folding arm 5.

[0027] The counterweight frame 8 is located at the rear end of the rotating arm 2. The bottom of the counterweight frame 8 is equipped with load-bearing rollers 81, which roll in contact with the deck 72. The counterweight frame 8 contains a counterweight body, which is used to balance the weight of the front end of the rotating arm 2 and one side of the folding arm 5.

[0028] A handle 82 is provided at the rear end of the rotating arm 2, specifically at the rear end of the counterweight frame 8. When there is no power mechanism, the handle 82 is used by the operator to manually push and pull to make the rotating arm 2 rotate horizontally relative to the base 1.

[0029] The rotating component is configured as a slewing bearing. The fixed end of the slewing bearing is connected to the base 1, and the rotating end of the slewing bearing is connected to the middle position of the rotating arm 2. A power mechanism drives the rotating end of the slewing bearing to rotate relative to the fixed end, so that the rotating arm 2 rotates horizontally relative to the base 1. A gear ring is provided around the circumference of the rotating end of the slewing bearing. The power mechanism includes a motor, and the output shaft of the motor is connected to a drive gear, which meshes with the gear ring. The output shaft of the motor drives the drive gear to rotate, which in turn drives the gear ring to rotate, causing the rotating end of the slewing bearing to rotate relative to the fixed end.

[0030] Two anti-slip strips 51 are provided on the articulated arm 5. The anti-slip strips 51 are arranged along the extension direction of the articulated arm 5. A row of support rollers 52 is provided on each side of the anti-slip strips 51 on the articulated arm 5.

[0031] When the pressure applied by the locking release 6 to the marine equipment 7 does not reach a set threshold, the support roller 52 protrudes from above the anti-slip strip 51 to roll into contact with the marine equipment 7. This "pressure applied by the locking release 6 not reaching the set threshold" includes the locking release 6 not applying any pressure to the marine equipment 7. Thus, the folding arm 5 only rolls into contact with the marine equipment 7 via the support roller 52, and the marine equipment 7 disengages from the anti-slip strip 51. After the folding arm 5 swings vertically downwards at a set angle relative to the rotating arm 2, the marine equipment 7 only rolls into contact with the support roller 52 and slides off the folding arm 5 into the water.

[0032] When the locking release device 6 applies pressure to the marine equipment 7 to a set threshold, the support roller 52 does not protrude from above the anti-slip strip 51, causing the marine equipment 7 to abut against the anti-slip strip 51. Under the pressure of the locking release device 6 and with the anti-slip strip 51 abutting against the marine equipment 7, the marine equipment 7 can be stably fixed to the folding arm 5, preventing the marine equipment 7 from falling off the folding arm 5 during transportation.

[0033] The anti-slip strip 51 has a rubber surface on the end face that contacts the marine equipment 7, or the entire anti-slip strip 51, to prevent the anti-slip strip 51 from scratching the marine equipment 7. The outer surface of the support roller 52 that contacts the marine equipment 7 is also made of rubber to prevent the support roller 52 from scratching the marine equipment 7.

[0034] A first slide rail 53 is provided on the articulated arm 5, and the first slide rail 53 is arranged radially along the articulated arm 5. A groove 50 is formed on the articulated arm 5, and the first slide rail 53 is arranged on the opposite side of the groove 50. The first slide rail 53 has a slotted structure, and a first slide block 54 is slidably fitted onto the first slide rail 53. The first slide block 54 is located within the groove 50, and its edge is embedded in the slotted structure. The inner end of the first slide block 54 is connected to the bottom of the groove 50 of the articulated arm 5 via an elastic element 55 (spring), and the outer end of the first slide block 54 is rotatably connected to a support roller 52 via a rotating shaft.

[0035] When the pressure applied by the locking release device 6 to the marine equipment 7 does not reach the set threshold, under the elastic force of the elastic element 55, the elastic element 55 returns to its original position and extends, the first slide block 54 slides upward relative to the first slide rail 53, and the support roller 52 moves upward and protrudes from above the anti-slip strip 51 to roll and contact the marine equipment 7.

[0036] When the locking release device 6 applies pressure to the marine equipment 7 to reach the set threshold, it overcomes the elastic force of the elastic element 55, the elastic element 55 is compressed, the first slide block 54 slides downward relative to the first slide rail 53, the support roller 52 moves downward and the support roller 52 is not exposed above the anti-slip strip 51, so that the marine equipment 7 abuts against the anti-slip strip 51.

[0037] The bottom of the articulated arm 5 has a through slot 56 along its extension direction to accommodate protruding structures on the marine equipment 7 (such as antennas, sensors, rudders, etc.).

[0038] The locking release device 6 includes a support base 61, a second slide rail 621, a second slide block 622, a third slide rail 631, a third slide block 632, a clamping rod 641, a connecting rod 642, a second telescopic cylinder 65, a gripper 66, and a transition rod 67.

[0039] A support base 61 is mounted on the folding arm 5. A second slide rail 621 is provided at both the front and rear ends of the support base 61, extending along the left and right directions of the folding arm 5. Each second slide rail 621 has a second sliding block 622 slidably engaged on its left and right sides. A third slide rail 631 is provided at both the front and rear ends of the support base 61, extending along the front and rear directions of the folding arm 5. Each third slide rail 631 has a third sliding block 632 slidably engaged on its left side. The two ends of the left-side clamping rod 641 are connected to the left-side second sliding block 622, and the two ends of the right-side clamping rod 641 are connected to the right-side second sliding block 622. One end of the connecting rod 642 is hinged to the end of the clamping rod 641 or the second sliding block 622, and the other end of the connecting rod 642 is hinged to the third sliding block 632 on the same side. Both ends of the second telescopic cylinder 65 are hinged to a third sliding block 632. The lower ends of the grippers 66 are hinged to the left and right sides of the support base 61. Each of the left and right gripping rods 641 has a transition rod 67, the end of which is movably connected to the middle position of the gripper 66 on the same side. An elongated hole 661 is formed in the middle position of the gripper 66, and a hinge shaft 671 is provided at the end of the transition rod 67. The hinge shaft 671 can rotate relative to the elongated hole 661 and can also slide relative to the elongated hole 661.

[0040] The two ends of the second telescopic cylinder 65 extend relative to each other, the two third slides 632 move away from each other, the two clamping rods 641 move closer to each other, and the transition rod 67 drives the claw 66 to press against the marine equipment 7, thereby locking the marine equipment 7 onto the folding arm 5.

[0041] The two ends of the second telescopic cylinder 65 retract relative to each other, the two third slides 632 move closer to each other, the two clamping rods 641 move further apart, and the transition rod 67 drives the gripper 66 to detach from the marine equipment 7, thereby releasing the marine equipment 7 from the folding arm 5.

[0042] A fourth slide rail 57 is provided on the articulated arm 5, which is arranged along the extension direction of the articulated arm 5. The support base 61 is slidably engaged with the fourth slide rail 57. In this way, the position of the support base 61 in the extension direction of the articulated arm 5 can be adjusted so that the gripper 66 can be clamped at different positions on the marine equipment 7.

[0043] A method for rapid deployment of marine equipment, using the rotary articulated boom type rapid deployment device for marine equipment described in this embodiment, includes the following steps: S1. Place the marine equipment 7 to be deployed on the folding arm 5, and lock and fix the marine equipment 7 on the folding arm 5 using the locking release device 6.

[0044] First, based on the size and center of gravity of the marine equipment 7, adjust the support seat 61 of the locking release device 6 to a suitable position along the fourth slide rail 57 on the folding arm 5. Place the marine equipment 7 to be deployed above the folding arm 5, so that the bottom of the marine equipment 7 contacts the support roller 52 on the folding arm 5, and roll the marine equipment 7 along the support roller 52 to position it in the set position on the folding arm 5. At the same time, ensure that the protruding structures at the bottom of the marine equipment 7 (such as antennas, sensors, rudders, etc.) pass through the through slot 56 opened at the bottom of the folding arm 5. Next, control the two ends of the second telescopic cylinder 65 to extend relative to each other, drive the two third slide seats 632 to move away from each other along the third slide rail 631, and drive the two clamping rods 641 to move closer to each other through the connecting rod 642; when the clamping rods 641 move, the transition rod 67 drives the gripper 66 to rotate around its lower hinge axis and press against the top or side of the marine equipment 7. As the second telescopic cylinder 65 continues to extend, the pressure applied by the locking release device 6 to the marine equipment 7 reaches the set threshold. At this time, the elastic force of the elastic element 55 is overcome, causing the first slide block 54 to slide downward along the first slide rail 53. The support roller 52 moves downward until it is no longer exposed above the anti-slip strip 51. The bottom surface of the marine equipment 7 directly abuts against the anti-slip strip 51, thereby stably locking and fixing the marine equipment 7 to the folding arm 5 and preventing it from falling off during transportation.

[0045] S2. Drive the rotating arm 2 to rotate relative to the base 1 along the horizontal plane, so that the rotating arm 2 drives the folding arm 5 to rotate from the inside of the ship's side 71 to the outside of the ship's side 71.

[0046] The power mechanism (motor) is activated, and the motor's output shaft drives the drive gear to rotate. The drive gear meshes with the gear ring of the slewing bearing, driving the rotating end of the slewing bearing to rotate relative to the fixed end, thereby causing the rotating arm 2 to rotate horizontally relative to the base 1. As the rotating arm 2 rotates, the load-bearing roller 81 at the bottom of the counterweight frame 8 at its rear end rolls along the deck 72. The counterweight within the counterweight frame 8 balances the weight of the front end of the rotating arm 2 and one side of the folding arm 5, ensuring smooth rotation. The rotating arm 2, along with the folding arm 5 and the marine equipment 7 locked to it, rotates horizontally from the initial position inside the ship's side 71 to above the waterline outside the ship's side 71. In the absence of power or a power outage, the operator can manually complete the rotation by pushing or pulling the handle 82 at the rear end of the counterweight frame 8.

[0047] S3. Drive the articulated arm 5 to swing vertically downward relative to the rotating arm 2, so that the marine equipment 7 on the articulated arm 5 approaches the water surface or enters the water.

[0048] One end of the first telescopic cylinder 4 extends relative to the other end. Since the two ends of the first telescopic cylinder 4 are hinged to the rear ends of the rotating arm 2 and the swing seat 3 respectively, and the swing seat 3 has a V-shaped structure with the front end of the rotating arm 2 hinged in its middle, when the first telescopic cylinder 4 extends, it pushes the swing seat 3 to swing downwards around its hinge point with the rotating arm 2. The swing seat 3 drives the folding arm 5 connected to its front end to swing vertically downwards relative to the rotating arm 2, causing the marine equipment 7 at the front end of the folding arm 5 to gradually descend and approach the water surface or partially enter the water. During this process, since the locking release device 6 maintains the set threshold pressure applied to the marine equipment 7, the support roller 52 remains concealed, and the marine equipment 7 remains stably abutted against the anti-slip strip 51, preventing premature slippage due to gravity.

[0049] S4. Control the locking release device 6 to release the marine equipment 7 from the folding arm 5, completing the deployment.

[0050] Once the marine equipment 7 has descended to the target water area and its main body is submerged and buoyancy or attitude is stable, the two ends of the second telescopic cylinder 65 controlling the locking release device 6 retract relative to each other, driving the two third slide blocks 632 to move closer together along the third slide rail 631. This, in turn, causes the two clamping rods 641 to move away from each other via the connecting rod 642. As the clamping rods 641 move, the transition rod 67 drives the gripper 66 to rotate in the opposite direction around its lower hinge axis, causing the gripper 66 to disengage from the marine equipment 7. At this time, the pressure applied to the marine equipment 7 by the locking release device 6 drops below a set threshold (i.e., no more pressure is applied), the elastic element 55 (spring) returns to its original position and extends, pushing the first slide block 54 to slide upwards along the first slide rail 53, causing the support roller 52 to move upwards and protrude above the anti-slip strip 51. Under the influence of gravity, the marine equipment 7 forms rolling contact with the exposed support roller 52 and automatically slides down along the extension direction of the folding arm 5, smoothly entering the water, completing the rapid deployment of the marine equipment 7.

[0051] Example 2: like Figures 10 to 17 As shown, the difference between this embodiment and Embodiment 1 is that the locking release device 6 in this embodiment includes a support base 61, a reduction motor assembly 68, and a gripper 66. The support base 61 is slidably engaged with the fourth slide rail 57 on the folding arm 5. The reduction motor assembly 68 is disposed on the support base 61, and the output end of the reduction motor assembly 68 is connected to the gripper 66.
