[0061] Reference Figure 1 to Figure 7, is an embodiment of the present invention, an adaptive multi-diameter locking salvage device is proposed, including: a mounting member 1; a clamping assembly 2, the clamping assembly 2 is movably arranged on the mounting member 1, the clamping assembly 2 includes: a clamping plate 3, the clamping plate 3 has two, the two clamping plates 3 are slidably arranged on the mounting member 1, the two clamping plates 3 form a clamping gap 4, after the two clamping plates 3 slide on the mounting member 1, they are used to adjust the size of the clamping gap 4, the clamping plate 3 has a plurality of sliding gaps 5; a clamping block 6, the clamping block 6 has a plurality of, the plurality of clamping blocks 6 are respectively slidably arranged in the plurality of sliding gaps 5, and the plurality of clamping blocks 6 are symmetrically distributed, after the clamping blocks 6 slide in the sliding gap 5, they are used to adjust the size of the clamping gap 4; a synchronous drive assembly 7, the synchronous drive assembly 7 is arranged on the clamping plate 3, and the synchronous drive assembly 7 is used to drive the plurality of clamping blocks 6 to move synchronously.

[0062] In this embodiment, the adaptive multi-diameter locking salvage device is first installed on the work platform on the corresponding ship. An underwater camera or other sensor equipment is used to identify the target object to be salvaged and determine its diameter. According to the diameter of the target object, the synchronous drive component 7 is operated to move the clamping plate 3 and the clamping block 6 to the appropriate position to form a suitable clamping gap 4. The device is moved above the target object, and the clamping block 6 is controlled to move synchronously inward by the synchronous drive component 7, and the clamping gap 4 is gradually reduced until the clamping block 6 firmly locks the target object. Before salvaging, check whether the clamping blocks 6 are evenly distributed and the clamping force is moderate to ensure that the target object is safely locked. After confirming that everything is ready, start the salvage device and lift the target object from underwater to the surface. After the salvage is completed, the device is recovered and necessary inspections and maintenance are performed to ensure its performance when it is used again. The device can adapt to drill pipes or pipes of different diameters, and stable clamping of targets of different diameters can be achieved by adjusting the size of the clamping gap 4. The sliding arrangement of the clamping plate 3 and the clamping block 6 provides flexibility, allowing the device to adapt to the salvage requirements of different diameters without changing its own structure. By moving the clamping block 6 in the sliding gap 5, the clamping gap 4 can be accurately adjusted to ensure that the tightening force on the target object is moderate and avoid damage. The symmetrical distribution design of the clamping block 6 helps to maintain balance during the salvage process and reduce equipment damage or salvage failure caused by uneven force. The synchronous drive assembly 7 ensures that all clamping blocks 6 can move at the same time, which improves the adjustment speed and efficiency, and ensures the consistency of the clamping action. Since the drill rod has a step, the clamping block 6 located on the clamping assembly 2 can play a certain supporting role on the step of the drill rod when the drill rod is clamped, so that the effect of clamping and lifting the drill rod of this scheme is improved, and the drill rod is further prevented from slipping during the clamping process. When the clamping assembly 2 is not clamping a thicker part, if the drill rod slips, the clamping block 6 located at the top of the clamping assembly 2 will also generate a supporting force on the step of the drill rod to prevent the drill rod from falling off the clamping assembly 2.

[0063] Optionally, the clamping plate 3 has a plurality of guide grooves 8, and the synchronous drive assembly 7 includes: a guide rod 9, which has a plurality of guide rods 9, which are arranged on the clamping block 6 in a one-to-one correspondence, and the plurality of guide rods 9 are slidably arranged in the guide groove 8 in a one-to-one correspondence; a first rack 10, which has a plurality of first racks 10, which are all arranged on the guide rod 9 and slidably arranged on the mounting member 1, and after the guide rod 9 slides in the guide groove 8, it is used to drive the first rack 10 in Slide on the mounting member 1; arc-shaped teeth 11, there are a plurality of arc-shaped teeth 11, the arc-shaped teeth 11 have a hinged end 12, the plurality of arc-shaped teeth 11 are hingedly arranged on the mounting member 1 through the hinged end 12, and the plurality of arc-shaped teeth 11 are meshed with a plurality of first racks 10 one by one, and after the arc-shaped teeth 11 rotate on the mounting member 1, they are used to drive the first rack 10 to slide on the mounting member 1; a driving member 13, arranged on the mounting member 1, the driving member 13 is used to drive the plurality of arc-shaped teeth 11 to rotate synchronously.

[0064] In this embodiment, before operation, check whether the guide groove 8, the guide rod 9, the first rack 10 and the arc-shaped teeth 11 are intact to ensure that there is no damage or wear. Use underwater detection equipment to identify the target object and measure its diameter to provide data support for adjusting the clamping gap 4. Operate the driving member 13 to drive the arc-shaped teeth 11 to rotate synchronously. The rotation of the arc-shaped teeth 11 drives the first rack 10 to slide on the mounting member 1, thereby pushing the guide rod 9 to move. The movement of the guide rod 9 drives the clamping block 6 to slide on the clamping plate 3 to adjust the clamping gap 4. When the clamping gap 4 is adjusted to a diameter suitable for the target object, stop the operation of the driving member 13 to ensure that the clamping block 6 firmly locks the target object. Before salvaging, check again whether the clamping blocks 6 are evenly distributed and firmly lock the target to ensure the safety of the salvage process. After confirming that everything is ready, start the salvage device and lift the target object from underwater to the surface according to the predetermined operating procedure. The coordinated use of the guide groove 8 and the guide rod 9 ensures the precise guidance of the clamping block 6 during movement, prevents deviation or jamming, and improves the accuracy and reliability of clamping. Through the meshing of the first rack 10 and the arc-shaped teeth 11, the synchronous movement of the clamping block 6 is achieved, the uniform adjustment of the clamping gap 4 is ensured, and damage or salvage failure caused by uneven clamping is avoided. The design of the arc-shaped teeth 11 allows the rack to slide by rotation, providing a flexible adjustment method to adapt to salvage objects of different diameters. The combined design of the guide rod 9, the first rack 10 and the arc-shaped teeth 11 makes the entire synchronous drive assembly 7 compact, reduces space occupancy, and is convenient for operation in a limited space. The setting of the drive member 13 allows the arc-shaped teeth 11 to rotate synchronously, thereby quickly driving the first rack 10 to slide, improving the response speed and operating efficiency of the salvage device. The design of the hinged end 12 provides a stable support point for the arc-shaped teeth 11, enhancing the reliability and durability of the entire synchronous drive assembly 7. Due to the clear component design and simple structure, it is easy to inspect and maintain, reducing maintenance costs in long-term operation.

[0065] Optionally, it also includes: a cover plate 14, which is arranged on the mounting member 1, and the cover plate 14 is used to cover the synchronous drive assembly 7; the arc-shaped tooth 11 has a swinging end 15, and the driving member 13 includes: a lifting plate 16, the lifting plate 16 is movably arranged on the mounting member 1, and the moving direction of the lifting plate 16 on the mounting member 1 is perpendicular to the sliding direction of the first rack 10, and the swinging ends 15 of several arc-shaped teeth 11 are hingedly arranged on the lifting plate 16, and after the lifting plate 16 moves on the mounting member 1, it is used to drive the several arc-shaped teeth 11 to rotate around the hinged end 12; a telescopic member 17, the telescopic member 17 is arranged on the inner wall of the cover plate 14, and the telescopic end of the telescopic member 17 is arranged on the lifting plate 16, and after the telescopic member 17 is extended and retracted, it is used to drive the lifting plate 16 to move.

[0066] In this embodiment, the setting of the cover plate 14 provides physical protection for the synchronous drive assembly 7 to prevent collision, corrosion or other potential damage during underwater operations. The design of the lifting plate 16 and the telescopic member 17 increases the structural stability of the entire synchronous drive assembly 7, making the rotation of the arc-shaped teeth 11 more stable and reliable. The setting of the cover plate 14 helps to optimize the spatial layout of the equipment, making the synchronous drive assembly 7 more compact and convenient for operation in a limited space. The lifting plate 16 is driven to move by the telescopic member 17, thereby realizing the rotation of the arc-shaped teeth 11, simplifying the operation process and improving the simplicity of operation. The rapid telescopic ability of the telescopic member 17 can quickly adjust the position of the lifting plate 16, thereby quickly changing the angle of the arc-shaped teeth 11 and improving the speed of adjusting the clamping gap 4. The combination of the lifting plate 16 and the telescopic member 17 provides a way to accurately control the rotation angle of the arc-shaped teeth 11, ensuring the precise adjustment of the clamping gap 4. The design of the cover plate 14 facilitates regular inspection and maintenance of the synchronous drive assembly 7, improving the maintenance efficiency of the equipment. Before operation, check whether the cover plate 14, lifting plate 16, telescopic member 17 and arc-shaped teeth 11 are intact to ensure that there is no damage or wear. Use underwater detection equipment to identify the target object and measure its diameter to provide data support for adjusting the clamping gap 4. Operate the telescopic member 17 so that its telescopic end drives the lifting plate 16 to move on the mounting member 1. The movement of the lifting plate 16 causes the arc-shaped teeth 11 to rotate around the hinged end 12, thereby driving the first rack 10 to slide, thereby adjusting the clamping gap 4. When the clamping gap 4 is adjusted to a diameter suitable for the target object, stop the operation of the telescopic member 17 to ensure that the clamping block 6 firmly locks the target object. Before salvaging, check the working status of the synchronous drive assembly 7 in the cover plate 14 again to ensure that the clamping blocks 6 are evenly distributed and firmly lock the target. After confirming that everything is ready, start the salvage device and lift the target object from underwater to the surface according to the predetermined operating procedure.

[0067] Optionally, it further includes: a lifting device 18, which is arranged on the mounting member 1 and is used to drive the mounting member 1 to rise and fall.

[0068] In this embodiment, the addition of the lifting device 18 provides vertical movement capability in addition to the horizontal direction, so that the mounting member 1 can be adjusted in the vertical direction according to the needs of the salvage task. Through the lifting device 18, the salvage device can more flexibly adapt to different operating depths and environmental conditions, improving the adaptability and flexibility of the operation. The lifting device 18 enables the salvage device to approach the target or evacuate from the target faster, reducing the time for finding and locating the target.

[0069] Optionally, the lifting device 18 includes: a frame 19, which is used to be set on the platform; a first mounting plate 20, which is set on the frame 19; a first gear 21, which is rotatably set on the first mounting plate 20; a second gear 22, which has a plurality of second gears 22, and the plurality of second gears 22 are rotatably set on the first mounting plate 20, and the plurality of second gears 22 are circumferentially distributed on the outside of the first gear 21, and the plurality of second gears 22 are meshed with the first gear 21; a threaded rod 23, which has a plurality of threaded rods 23, and the plurality of threaded rods 23 are all set at one end on the cover plate 14, and the other end is threadedly set on the plurality of second gears 22, and after the plurality of second gears 22 rotate, they are used to drive the plurality of threaded rods 23 to be lifted and lowered.

[0070] In this embodiment, the setting of the frame 19 provides a stable base for the entire lifting device 18, ensuring stability and safety during the lifting process. Through the cooperation of the threaded rod 23 and the second gear 22, the height of the cover plate 14 can be accurately adjusted, so that the salvage device can adapt to the operation requirements of different heights. The meshing design of multiple second gears 22 and the first gear 21 ensures the synchronous lifting and lowering of the threaded rod 23, avoiding the tilting or damage of the equipment caused by asynchronous lifting. The rotation design of the first gear 21 and the second gear 22 simplifies the operation process. The lifting and lowering of the cover plate 14 can be achieved by rotating the gears, which improves the convenience of operation. The design of the lifting device 18 enables the salvage device to be quickly adjusted to a suitable working height, reducing the operation preparation time and improving the operation efficiency.

[0078] S3, fine-tuning the clamping assembly 2: driving the first gear 21 to rotate, thereby driving the second gear 22 to rotate synchronously, and the second gear 22 is engaged with the thread of the threaded rod 23 to achieve the linear downward movement of the threaded rod 23, so that the clamping assembly 2 is completely aligned with the target drill rod;

[0079] S4, second salvage action: operate the third gear 30 to rotate, prompting the two clamping plates 3 to perform a closing action and perform a preliminary clamping on the drill rod. If the drill rod is successfully clamped, start the first gear 21 to rotate in the opposite direction to lift the salvage device.

[0081] In this embodiment, the adaptive multi-diameter locking salvage device is an innovative engineering device, which achieves stable clamping and salvaging of targets with different diameters through a series of precisely designed components and synchronous drive mechanisms. The clamping assembly 2 of the device consists of two clamping plates 3 and multiple clamping blocks 6, which can slide on the mounting member 1 to adjust the size of the clamping gap 4 to adapt to salvage objects with different diameters. The sliding gap 5 design of the clamping plate 3 allows the clamping blocks 6 to move synchronously therein, ensuring uniform distribution of the clamping force and precise locking of the target.

[0082] The introduction of the synchronous drive assembly 7 realizes the synchronous movement of the clamping block 6 through the cooperation of the guide rod 9, the first rack 10 and the arc-shaped teeth 11, thereby improving the clamping efficiency and stability.

[0083] The addition of the lifting device 18 enables the entire salvage device to be raised and lowered as needed, thereby expanding the salvage range and improving the flexibility of the operation. The design of the frame 19 allows the mounting frame 24 to be closely integrated with the platform, ensuring the stability of the entire device. The coordinated use of the pulling rope 26 and the winch 27 further improves the control accuracy and convenience of the salvage process.

[0084] The design of the winding wheel 28 and the second rack 29 provides guidance for the pulling rope 26, ensuring the neat arrangement of the rope and reducing confusion during operation. The cooperation between the third gear 30 and the second rack 29 enables the clamping plate 3 to be opened and closed as needed, adapting to salvage objects of different diameters. Overall, the adaptive multi-diameter locking salvage device has demonstrated significant technical advantages in the fields of marine engineering, rescue and salvage with its high adaptability, stability and ease of operation.

[0085] The method of using the adaptive multi-diameter locking salvage device is carried out in steps to ensure the accuracy and safety of the operation. First, in the S1 stage, the mounting frame 24 of the frame 19 needs to be leveled and installed to ensure its horizontality, which is to ensure the stability of the entire device during operation. Then, in the S2 stage, the pulling rope 26 and the clamping assembly 2 are lowered by the winch 27 to position the target drill pipe. This step is to ensure the accuracy of the subsequent clamping action.

[0086] In the S3 stage, the first gear 21 is driven to rotate, which drives the second gear 22 to rotate synchronously, so as to realize the linear downward movement of the threaded rod 23, so that the clamping assembly 2 is aligned with the target drill rod. This step is the key to the clamping process and requires precise control to ensure that the clamping assembly 2 can be fully aligned with the target.

[0087] The S4 stage is the core of the salvage operation. The third gear 30 is operated to rotate, prompting the two clamping plates 3 to perform a closing action and initially clamp the drill pipe. If the clamping is successful, the first gear 21 is started to rotate in the opposite direction to lift the salvage device. If the clamping fails, the telescopic member 17 is started to drive the lifting plate 16 to move and achieve accurate clamping of the drill pipe. This step reflects the adaptive characteristics of the device, which can be adjusted according to drill pipes of different diameters.

[0088] Finally, in stage S5, after confirming that the drill pipe is firmly clamped by the clamping assembly 2, the third gear 30 is operated again to drive the drill pipe to move upward along the threaded rod 23. When the drill pipe is lifted to the specified height, the pull rope 26 is wound up by the winch 27 to lift the drill pipe to the platform, completing a single salvage cycle. This step is the end of the entire salvage process, ensuring the safe recovery of the salvaged object.

[0089] The design of the entire method of use fully considers the simplicity and safety of operation, so that even in complex environments, the salvage task can be completed efficiently and accurately. Through this step-by-step operation process, the adaptive multi-diameter locking salvage device can be widely used in various salvage scenarios, demonstrating its strong practicality and reliability.
