[0024] Embodiment 1, combined with Figure 1 and Figure 2 To explain:

[0025] A limit structure for a marine rescue and transfer device includes: a rotation limit block 1 and a vertical motion limit assembly 2. By setting the rotation limit block 1 and the vertical motion limit assembly 2, the limit operation is simple and easy, which is convenient for rescue personnel to quickly and accurately locate and fix the transfer cabin. In the rescue operation, fast and accurate limit can significantly improve the rescue efficiency and shorten the rescue time.

[0026] The rotation limit block 1 comprises: a limit portion 11 and a rotation portion 12. The limit portion 11 and the rotation portion 12 are an integrated structure. Through the integrated design, the stable mechanical performance can be improved and the device can withstand a large external force without being easily damaged.

[0027] The rotating part 12 is rotatably connected to a guardrail 3 of a marine rescue and transfer device. A first limiting surface 111 is arranged on the lower side of the limiting part 11, and a second limiting surface 121 is arranged on one side of the rotating part 12. The first limiting surface 111 and the second limiting surface 121 are used together to limit the chassis guardrail 4 of a transfer cabin of a marine rescue and transfer device. Through the limiting structure, the transfer cabin can be effectively fixed and stabilized to prevent the transfer cabin from shifting due to wave impact and other reasons during operations at sea, thereby ensuring the safety of rescuers and rescued persons.

[0028] The vertical motion limiting assembly 2 is fixedly connected to the guardrail 3, and the vertical motion limiting assembly 2 is used to limit the vertical motion of the rotation limiting block 1. Thus, the limit can be effectively reduced to reduce the risk of damage to the transfer cabin and its guardrail during the transfer process.

[0029] Embodiment 2, based on embodiment 1, combined with Figure 3 To explain:

[0030] A first limiting block 112 is disposed at the lower side of the first limiting surface 111 . The first limiting block 112 is cylindrical and is used to limit a chassis guardrail 4 of a transfer cabin of a marine rescue transfer device.

[0031] A second limiting block 122 is disposed on the front side of the second limiting surface 121 . The second limiting block 122 is cylindrical and is used to limit a chassis guardrail 4 of a transfer cabin of a marine rescue transfer device.

[0032] In this way, the cylindrical stopper can evenly distribute the pressure on the contact surface, reduce local pressure concentration, and thus reduce damage to the transfer tank chassis guardrail 4. The cylindrical structure produces less friction when rotating than other shapes such as angles or planes, which makes it easier to adjust and move the stopper during the limiting process. The cylindrical stopper can provide a stable support point, which helps to maintain the stability of the transfer tank, especially in rough sea environments. The cylindrical structure is simple and is not easy to accumulate dirt or seawater corrosion, so it is easier to clean and maintain.

[0033] Embodiment 3, based on embodiment 2, combined with Figure 4 To explain:

[0034] The vertical motion limiting assembly 2 includes: a first limiting plate 21 and a second limiting plate 22 , which are fixedly connected to the guardrail 3 , wherein the first limiting plate 21 is arranged on the upper side of the rotating part 12 , and the second limiting plate 22 is arranged on the lower side of the rotating part 12 .

[0035] With such arrangement, the first limit plate 21 and the second limit plate 22 can effectively limit the vertical movement of the rotation limit block 1, preventing it from moving up and down due to vibration or impact during offshore operation, thereby ensuring the stability of the transfer device.

[0036] Embodiment 4, based on embodiment 3, combined with Figure 5 To explain:

[0037] A first anti-rotation portion 123 is disposed at the lower portion of the rotating portion 12 , and a second anti-rotation portion 221 is disposed on the second limiting plate 22 . The first anti-rotation portion 123 and the second anti-rotation portion 221 are connected via a latch 5 .

[0038] In this way, the first anti-rotation part 123 and the second anti-rotation part 221 are connected by a latch, which can effectively prevent the rotation limit block 1 from rotating in unexpected circumstances, ensuring that the transfer device remains in a fixed position during the rescue process. By limiting rotation, this structure increases the stability of the entire transfer device, especially in a sea environment with strong winds and waves, which helps to keep the transfer cabin stable. The latch connection method is simple and fast, and rescuers can quickly lock or unlock the anti-rotation structure for easy operation.

[0039] Working principle of the utility model: when the utility model is in use, the transfer cabin is put in, and then the rotating part 12 is rotated so that the first limit block 112 and the second limit block 122 limit the chassis guardrail 4, and then the first anti-rotation part 123 and the second anti-rotation part 221 are fixed together using the pin 5, so as to prevent the rotating part 12 from rotating. When the transfer cabin needs to be taken out, the pin 5 is unplugged, and the rotating part 12 is rotated so that the first limit block 112 and the second limit block 122 are rotated to the other side, and then the transfer cabin is taken out. The utility model has a simple structure and can well limit the transfer cabin installed on the chassis. When the transfer cabin needs to be removed, the rotating limit block 1 can be directly rotated to avoid bumps in the transfer cabin during transportation.
