For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0058] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0059] This embodiment provides an underwater decoupling device, such as Figure 1-Figure 4 As shown, it includes: a hook body 1, a hook-shaped portion 11, a connecting rod assembly and a traction rope 5.

[0060] One side of the hook body 1 has a slot 12 .

[0061] The hook portion 11 is hinged to the hook body 1 and can be moved toward or away from the hook body 1 by rotation; when the hook portion 11 is against the hook body 1, an internal space 111 capable of accommodating the sling 9 is formed between the hook portion 11 and the hook body 1.

[0062] The connecting rod assembly includes a connecting rod 2, a hook 3 and a buckle 4; the connecting rod 2 is hinged to the hook body 1, one end of which is fixedly connected to the hook 3, and the other end is hinged to the buckle 4; the connecting rod 2 can at least reach a first position and a second position by rotating, such as Figure 1 As shown, when the connecting rod 2 is in the first position, the hook 3 can abut against the hook-shaped portion 11 and restrict its rotation; Figure 4 As shown, when the connecting rod 2 is located at the second position, the hook 3 is separated from the hook-shaped portion 11 .

[0063] The traction rope 5 is connected to the buckle 4 and is used to drive the buckle 4 to rotate relative to the connecting rod 2; Figure 1 As shown, when the connecting rod 2 is in the first position, the buckle 4 can be inserted into the slot 12. When the buckle 4 is inserted into the slot 12, the rotation of the connecting rod 2 is restricted, and the traction rope 5 can drive the buckle 4 to rotate relative to the connecting rod 2 to make the buckle 4 disengage from the slot 12. After the buckle 4 disengages from the slot 12, the connecting rod 2 can rotate, and as the traction rope 5 continues to be pulled, the connecting rod 2 rotates to the second position, the hook 3 is separated from the hook-shaped portion 11, and the hook-shaped portion 11 rotates freely.

[0064] The hook-shaped part 11 of the underwater dehooker is limited by the hook 3, and the hook 3 unlocks the hook-shaped part 11 by the rotation of the connecting rod 2, while the buckle 4 can limit the rotation of the connecting rod 2 and can remove the restriction through the connected traction rope 5. Therefore, when the crane lowers large concrete components such as fish reefs to the seabed through the tool of the utility model, the underwater dehooker will not automatically unhook. If the position of the concrete component needs to be adjusted, the crane can be started again for adjustment. After the adjustment is completed, the operator can pull the buckle 4 through the traction rope 5 to open the hook-shaped part 11, so that the lifting rope 9 can be removed from the internal space 111, and then the tool can be recovered, which improves the efficiency, safety and convenience of construction.

[0065] In an optional embodiment, if Figure 1 , Figure 2 As shown, the hook-shaped portion 11 is hinged to the lower end of the hook body 1, the upper end of the hook body 1 has a hanging hole 15 for connecting the crane, and the connecting rod 2 is hinged between the upper and lower ends of the hook body 1. In this embodiment, the connecting rod 2 is arranged between the upper and lower ends of the hook body 1, which can provide a relatively moderate range of motion for the connecting rod 2, so that the hook 3 abuts against the hook-shaped portion 11 and the buckle 4 is snapped into the slot 12.

[0066] In an optional embodiment, if Figure 1 , Figure 2 As shown, the hook-shaped portion 11 is located on the first side of the hook body 1, and the slot 12 is located on the second side of the hook body 1, and the second side is the opposite side of the first side. In this embodiment, the space on both sides of the hook body 1 is used to set components, which effectively reduces the length of the device. And the lever structure of the connecting rod 2 is used, and one end is lowered while the other end is raised, so that when the traction rope 5 pulls the buckle 4, the hook 3 at the other end of the connecting rod 2 can move.

[0067] In an optional embodiment, if Figure 2As shown, the underwater unhooking device 100 further includes a pulley 8. The pulley 8 is fixed to the second side of the hook body 1, and the towing rope 5 changes the towing direction through the pulley 8. In this embodiment, since the latch 4 needs to move downward in order for the hook 3 to move upward, and the operator generally needs to operate above the water surface, it is necessary to change the towing direction through the pulley to facilitate the operation of the operator. Preferably, the pulley 8 is fixed to the lower end of the hook body 1 through a fixing plate 7, making full use of the space at the lower end of the hook body 1 and also providing sufficient clearance for the connecting rod 2 located in the middle of the hook body 1.

[0068] In an alternative embodiment, as Figure 2 , Figure 4 shown, clamping plates 13 are fixed to both sides of the hook-shaped part 11. The clamping plates 13 are connected to the hook body 1 through a rotating shaft 14, enabling the hook-shaped part 11 to rotate relative to the hook body 1. Preferably, the center of gravity of the hook-shaped part 11 deviates from the rotating shaft 14 along the direction of gravity. Therefore, when the hook 3 disengages from the hook-shaped part 11, the hook-shaped part 11 will rotate around the rotating shaft 14 under its own gravity and move away from the hook body 1. Through this design, when the hook 3 is unlocked, the hook-shaped part 11 will rotate due to its own gravity to achieve unhooking.

[0069] In an alternative embodiment, as Figure 1 , Figure 3 shown, the side of the hook-shaped part 11 facing away from the internal space 111 has a first inclined surface 113, and the inner side of the hook 3 has a second inclined surface 31 that can fit with the first inclined surface 113. Both the first inclined surface 113 and the second inclined surface 31 form an acute angle with the extending direction of the connecting rod 2. The inclined surface design of this embodiment can provide an interlocking force between the hook 3 and the hook-shaped part 11 when they are in contact, ensuring that they will not loosen under slight shaking.

[0070] In an alternative embodiment, as Figure 1 , Figure 3 shown, the distance between the hinge point of the connecting rod 2 and the hook body 1 and the hook 3 is a, and the distance between the hinge point of the connecting rod 2 and the hook body 1 and the latch 4 is b, where a < b. In this embodiment, when the towing rope 5 pulls the latch 4, the connecting rod 2 acts as a force-saving lever, which can facilitate the operator to pull the hook 3 with a smaller pulling force.

[0071] In an alternative embodiment, as Figure 4 shown, the hook 3 has a protruding part 32; as Figure 1As shown, when the hook-shaped portion 11 abuts against the hook body 1, an opening 112 is formed between the hook-shaped portion 11 and the hook body 1 for the protrusion 32 to extend into the internal space 111; when the connecting rod 2 rotates, the protrusion 32 can push the hook-shaped portion 11 to rotate away from the hook body 1. In this embodiment, the design of the protrusion 32 can not only release the hook-shaped portion 11 when the hook 3 moves, but also provide assistance when the hook-shaped portion 11 rotates, so that it is quickly separated from the hook body 1, so that the rope 9 in the internal space 111 can be quickly removed.

[0072] In an optional embodiment, if Figure 3 As shown, the buckle 4 includes: a through hole 41 and a buckle head 42. The through hole 41 is for the traction rope 5 to pass through to connect the buckle 4; the buckle head 42 can be inserted into the slot 12; the buckle 4 includes an L-shaped rod body, and the through hole 41 and the buckle head 42 are respectively located at both ends of the L-shaped rod body. Figure 1 , Figure 4 As shown, through the L-shaped rod body design, the buckle 4 has a larger rotation range when being pulled, making the movable joint more flexible and free to drive the connecting rod 2.

[0073] This embodiment also provides a tool for hoisting artificial reefs, such as Figure 5 As shown, the underwater dehooking device 100 also includes a suspension rope 9, a connecting rope 10 and a crane connecting hook 200. The crane connecting hook 200 is configured to be suspended by a crane, one end of the connecting rope 10 is connected to the crane connecting hook 200, and the other end is connected to the underwater dehooking device 100; one end of the suspension rope 9 is connected to the crane connecting hook 200, and the other end is tied to the artificial reef 300 and inserted into the internal space 111 of the underwater dehooking device 100.

[0074] The tool for lifting artificial fish reefs provided in this embodiment can effectively improve the construction efficiency, safety and construction accuracy of the installation of components such as artificial fish reefs. On the one hand, it can avoid underwater operations of divers. On the other hand, the underwater unhooking device can avoid the sudden falling off of components caused by unhooking during lifting, thereby improving construction safety; furthermore, the unhooking of the underwater unhooking device is controllable, which can ensure that after the fish reef falls to the bottom, the fish reef can continue to be lifted for fine-tuning of the position to ensure the accuracy of the fish reef installation.

[0075] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
