[0001] This utility model relates to the field of salvage equipment, and in particular to a salvage mechanism based on hydrogel. Background Technology

[0002] In marine debris cleanup and underwater object retrieval operations, the rapid and efficient grabbing and retrieval of objects in the water is crucial. Traditional retrieval equipment typically relies on pneumatically driven grippers for grasping, requiring an air hose to connect the gas power source to the gripper for control. However, pneumatic retrieval mechanisms require time for connecting and securing the air hose and checking for leaks to prevent hasty installation that could affect the gripper's retrieval operation. For situations requiring rapid retrieval, the air hose connection and sealing checks are time-consuming. To enable retrieval operations quickly without the need for air hose connections, this invention proposes a hydrogel-based retrieval mechanism. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-6 The hydrogel-based retrieval mechanism shown includes a movable cylinder 1, and further includes a movable component and a water discharge component;

[0025] Specifically, the movable component is used for retrieving and gripping objects.

[0027] Specifically, the positioning slot 2 is welded and fixed to the movable cylinder 1, and the weld is treated with anti-corrosion. The slot of the positioning slot 2 is rectangular. The clamping part 3 includes a first transmission bar 302 and a second transmission bar 303 hinged to the end of the pull rod 101. The first transmission bar 302 is located on the side of the second transmission bar 303 away from the movable cylinder 1. The ends of the first transmission bar 302 and the second transmission bar 303 are hinged with clamping arms 301.

[0028] It should be noted that the side of the positioning slot block 2 is symmetrically hinged with a limiting strip 304. The end of the limiting strip 304 away from the positioning slot block 2 is hinged to the outside of the first transmission strip 302. During the movement of the pushing part, the pull rod 101 moves away from the positioning slot block 2, thereby driving the first transmission strip 302 and the second transmission strip 303 to rotate, so that the two clamping arms 301 move closer to each other to clamp the object.

[0029] Specifically, the pushing part includes a pressure block 103 disposed at the end of the pull rod 101. Drain holes 1031 are symmetrically disposed on the outer side of the pressure block 103. A hydrogel block 102 is sleeved on the outer side of the pull rod 101 and in the inner cavity of the movable cylinder 1. The hydrogel block 102 is disposed on the side of the pressure block 103 near the positioning groove block 2.

[0030] It should be noted that the pressure block 103 and the pull rod 101 are fixed together by bolts. The hydrogel block 102 is a hemicellulose / carbon nanotube composite hydrogel prepared by free radical polymerization. It has a porous structure, which expands when it absorbs water and shrinks when it loses water. The hydrogel block 102 can expand 4-8 times when it absorbs water. It belongs to a type of shape memory polymer and does not easily lose water due to compression.

[0031] Specifically, the inner wall of the movable cylinder 1 is provided with a water inlet groove 104, which is used for water to flow and contact the hydrogel block 102.

[0032] It should be noted that the water discharge assembly includes a water inlet sleeve 4 located at the other end of the movable cylinder 1. Multiple sets of water inlet holes 401 are arranged around the outer side of the water inlet sleeve 4. A block 402 for blocking the water inlet holes 401 is provided in the inner cavity of the water inlet sleeve 4. A traction part for pulling the block 402 away from the water inlet holes 401 is provided at the other end of the water inlet sleeve 4.

[0033] Specifically, the water discharge assembly is used to provide a push for water discharge. The water inlet sleeve 4 and the movable cylinder 1 are fixed by bolts through and tightened. The diameter of the water inlet hole 401 is 0.2 cm, and the plug 402 is made of rubber.

[0034] It should be noted that the traction unit includes a pull rope 5 located at the end of the block 402, a connecting sleeve 501 located at the end of the water inlet sleeve 4 and outside the pull rope 5, and a fixing sleeve 6 inserted and connected to the end of the pull rope 5 away from the water inlet sleeve 4.

[0035] Specifically, the cable 5 is made of steel cable and is glued to the block 402. The connecting sleeve 501 is made of plastic. The cable 5 can move in the inner cavity of the connecting sleeve 501. The end of the cable 5 is provided with a grip for connecting to the fixing sleeve 6. After the retrieval is completed, the water inlet sleeve 4 and the pressure block 103 can be directly disassembled to replace the hydrogel block 102.

[0036] It should be noted that the gripping component includes a rotating sleeve 601 that is inserted and connected to the outside of the draw rope 5. A limit block 502 is provided at the insertion point of the draw rope 5 and the rotating sleeve 601. The inner wall of one end of the rotating sleeve 601 is threadedly connected to the outer side of the fixed sleeve 6.

[0037] Specifically, the two ends of the connecting sleeve 501 are glued to the fixed sleeve 6 and the water inlet sleeve 4 respectively, the limiting block 502 is glued to the pull rope 5, the outer side of the fixed sleeve 6 is threaded, and the inner wall of the rotating sleeve 601 is threaded accordingly.

[0038] It should be noted that the operator needs to unscrew the rotating sleeve 601 first, and then pull the pull rope 5. The pull rope 5 moves in the inner cavity of the connecting sleeve 501, the fixed sleeve 6 and the water inlet sleeve 4.

[0039] In actual use, by configuring a water-swellable hydrogel block 102 in the inner cavity of the movable cylinder 1, the user only needs to pull the block 402 away from the water inlet 401 through the traction part, so that water can flow through the water inlet 401 into the interior of the movable cylinder 1. The hydrogel block 102 absorbs water and gradually expands, pushing the pull rod 101 to move, thereby driving the clamping part 3 to grab and retrieve objects in the water. Compared with the traditional pneumatic retrieval mechanism, this design does not require time to connect the air pipe and does not require carrying an air source, which facilitates quick retrieval operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
