[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides an integrated system for rapid deployment and recovery of a small boat, comprising a hull 6 and a first deployment device 1, a second deployment device 2, and a third deployment device 3 disposed within the hull 6 for placing a small boat 19. The second deployment device 2 and the third deployment device 3 are fixedly connected, while the first deployment device 1 and the second deployment device 2 are detachably connected. The first deployment device 1 is disposed at the bow of the hull 6.

[0022] A track 11 is installed inside the hull 6 along its central axis, on which the second and third deployment devices 2 and 3 slide. A base assembly is installed at the bottom of the hull 6. This base assembly includes several base columns 4, one end of which is fixed to the top of the hull 6, and the other end of which is fixed to the track 11. This base assembly ensures that the track 11 is securely installed inside the hull 6, ensuring that the second and third deployment devices 2 and 3 slide smoothly on the track 11.

[0023] The first laying device 1 includes a support 16, the upper part of which is mounted a main slide 14, and the lower part of which is rotatably mounted a mobile tire frame 22, which abuts against the passage track 11. The lower part of the mobile tire frame 22 is mounted a roller device 24, which is slidably mounted in cooperation with the passage track 11. The right part of the support 16 is rotatably mounted a secondary slide 18, and one side of the support 16 is mounted a rear cylinder 13, one end of which is fixed to the mobile tire frame 22, and the other end of which is fixed to the support 16. The other side of the support 16 is also mounted a front cylinder 21, one end of which is fixed to the support 16, and the other end of which is fixed to the secondary slide 18. The main slide 14 and the secondary slide 18 are rotatably connected to the support 16 via a rotating shaft 17.

[0024] A bow hatch 12 is rotatably mounted on the bow of the hull 6. A workspace reinforcement assembly 9 is mounted on this hatch 12. A fixed track 10 is mounted on this workspace reinforcement assembly 9. This track 10 is aligned and parallel to a transit track 11. A movable track 8 is mounted between the fixed track 10 and the transit track 11, and is movable on the transit track 11. The arrangement of the bow hatch 12 allows it to be opened when a small boat 19 is needed, facilitating its entry and exit. The workspace reinforcement assembly 9 enhances the structural strength of the bow hatch 12, ensuring its stability in harsh maritime environments.

[0025] The first deployment device 1 is detachably connected to the second deployment device 2 via a fastening rigging assembly 7, and the second deployment device 2 is secured to the third deployment device 3 via the fastening rigging assembly 7. The fastening rigging assembly 7 includes multiple steel cables and fastening devices. The tightness of the steel cables can be adjusted by adjusting the fastening devices, thereby achieving a detachable connection between the first deployment device 1 and the second deployment device 2, and a fixed connection between the second deployment device 2 and the third deployment device 3.

[0026] The second deployment device 2 includes a support 16, with the main slide 14 mounted on its upper portion. A mobile tire frame 22 is rotatably mounted on its lower portion, abutting against the passage track 11. A roller assembly 24 is mounted below the mobile tire frame 22, slidingly engaging with the passage track 11. A secondary slide 18 is rotatably mounted on the right side of the support 16. The structural design of the second deployment device 2 enables it to slide smoothly on the passage track 11, and provides stable support for the boat 19 through the main slide 14 and secondary slide 18.

[0027] The third deployment device 3 includes a support 16, with a main slide 14 mounted on the upper portion of the support 16. A mobile tire frame 22 is rotatably mounted on the lower portion of the support 16, and the mobile tire frame 22 abuts the passage track 11. A roller device 24 is mounted on the lower portion of the mobile tire frame 22, and the roller device 24 is slidably mounted on the passage track 11. A secondary slide 18 is rotatably mounted on the right portion of the support 16. The third deployment device 3 also includes a hydraulic pump station 5, a corner pulley 15, and a hydraulic winch 23. The hydraulic pump station 5 is mounted inside the third deployment device 3, and the hydraulic winch 23 is mounted on one side of the hydraulic pump station 5. The hydraulic pump station 5 is used to provide power to the hydraulic winch 23. The corner pulley 15 is mounted on the upper portion of the third deployment device 3. The hydraulic winch 23 is connected to a steel wire cable, which is wrapped around the corner pulley 15 and fixed to the hull 6. Through the cooperation of the hydraulic winch 23 and the steel wire rope, the recovery function of the boat 19 can be realized, thereby improving the recovery efficiency and safety.

[0028] Transition pads 20 are installed on one side of the first, second, and third deployment devices 1, 2, and 3, and are fixed to each other with bolts. Made of rubber, these pads offer excellent cushioning and shock absorption properties, reducing the impact of the boat 19 during deployment and recovery, protecting the boat 19 and the deployment devices.

[0029] In this embodiment, the main slides 14 and auxiliary slides 18 of the first, second, and third deployment devices 1, 2, and 3 are made of high-strength alloy steel, with a surface anti-corrosion treatment to withstand the corrosion of the marine environment. The roller assembly 24 is made of a wear-resistant material to ensure good sliding performance during long-term use.

[0030] The passage track 11 utilizes an H-shaped steel structure, offering high load-bearing capacity and stability. The movable track 8 is foldable and can be stowed when not in use, minimizing the internal space occupied by the hull 6. A precise docking mechanism connects the fixed track 10 and the passage track 11, ensuring a smooth transition between the two.

[0031] Both rear cylinder 13 and front cylinder 21 are double-acting hydraulic cylinders with an operating pressure of 20 MPa, providing sufficient thrust and pull to ensure smooth rotation of the main slide 14 and auxiliary slide 18 of the first deployment device 1. The hydraulic pump station 5 has a rated power of 15 kW, providing stable power output for the hydraulic winch 23.

[0032] During the deployment of the boat 19, the bow hatch 12 is first opened, and the movable track 8 is deployed, forming a continuous track system with the fixed track 10 and the pass track 11. Next, the angles of the main slide 14 and auxiliary slide 18 of the first deployment apparatus 1 are adjusted by controlling the rear cylinder 13 and the front cylinder 21, allowing the boat 19 to slide smoothly into the water along the slides. During the recovery of the boat 19, the hydraulic winch 23 tightens the steel cable, pulling the boat 19 back onto the third deployment apparatus 3. The second deployment apparatus 2 and the first deployment apparatus 1 then completely recover the boat 19 into the hull 6.

[0033] The integrated system of this embodiment is compact and easy to operate, enabling rapid deployment and recovery of the boat 19, thereby improving the efficiency and safety of offshore operations. Furthermore, the detachable connection design facilitates system maintenance and replacement, extending its service life.

[0036] The first deployment device 1 is detachably connected to the second deployment device 2 via an improved fastening rigging assembly 7, which in turn is secured to the third deployment device 3 via the improved fastening rigging assembly 7. The improved fastening rigging assembly 7 includes multiple high-strength steel cables and a quick-tightening device. The quick-tightening device utilizes a hydraulic drive mechanism, enabling fastening and loosening operations in a short time, improving the system's operational efficiency.

[0037] Composite transition pads 20 are installed on one side of the first, second, and third deployment devices 1, 2, and 3, and are fixed to each other with high-strength bolts. Made of a rubber and carbon fiber composite, these pads offer enhanced cushioning and durability, effectively reducing impact forces during the deployment and recovery of the boat 19.

[0038] The third laying device 3 includes a high-efficiency hydraulic pump station 5, a multi-angle corner pulley 15 and a variable-speed hydraulic winch 23. The high-efficiency hydraulic pump station 5 is installed inside the third laying device 3, and the variable-speed hydraulic winch 23 is installed on one side of the high-efficiency hydraulic pump station 5. The high-efficiency hydraulic pump station 5 is used to provide power to the variable-speed hydraulic winch 23. The multi-angle corner pulley 15 is installed on the upper part of the third laying device 3. The variable-speed hydraulic winch 23 is connected to a high-strength steel wire cable, which is fixed to the hull 6 after being wrapped around the multi-angle corner pulley 15. The rated power of the high-efficiency hydraulic pump station 5 is 20kW, which is more powerful than the hydraulic pump station 5 in Example 1 and can provide stronger power output. The variable-speed hydraulic winch 23 has a multi-speed adjustment function, which can adjust the recovery speed according to different recovery requirements, thereby improving the flexibility and safety of recovery.

[0039] The integrated system of this embodiment is improved on the basis of the first embodiment.
