Description

Technical Field

[0001] This utility model relates to the field of deep-sea equipment, and in particular to a deep-sea cylindrical object salvage clamp. Background Technology

[0002] The current salvage method mainly involves lowering a hooked cable from a mother ship to the seabed, then using a submersible to approach and hook the target to be salvaged. The mother ship then retrieves the cable carrying the target and finally retrieves the target onto the mother ship's deck.

[0003] Because this method involves fixed salvage using a hook, it cannot directly hook onto objects without a fixed hook point, such as underwater aircraft or submarine wreckage or other deep-sea equipment, thus making it impossible to salvage the object.

[0004] Existing methods use grippers to pick up target objects, but it is still difficult to retrieve cylindrical objects of different weights and sizes. Utility Model Content

[0005] To address the problem of being unable to salvage cylindrical objects of varying sizes and weights, this invention proposes a deep-sea cylindrical object salvage clamp.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a deep-sea cylindrical object salvage clamp comprising at least one clamp structure. The clamp structure includes a first clamp, a second clamp, and an adjustment component. The first clamp and the second clamp are rotatably connected. An adjustment mechanism connecting the first clamp and the second clamp is provided at the top of the clamp structure. The adjustment mechanism includes a connecting component, a first nut, and a threaded rod. The connecting component is fixed to the first clamp and the second clamp. The first nut is disposed on the connecting component of the first clamp and the second clamp. The threaded rod rotates to change the distance between the connecting component on the first clamp and the connecting component on the second clamp, thereby adjusting the clamping and loosening of the first clamp and the second clamp.

[0008] Furthermore, it also includes a connecting plate, which is connected to the clamp structure.

[0009] Furthermore, it also includes a first screw and a second nut, the first screw passing through the first clamp, the second clamp and the connecting plate, and connected to the second nut.

[0010] Furthermore, a first hook point is provided on the top of the connecting plate.

[0011] Furthermore, it also includes a main beam, the bottom of which is provided with at least one adjustable suspension chain, one end of which is connected to the first hook point and the other end of which is connected to the main beam.

[0012] Furthermore, a second hook point is provided at the top of the main beam.

[0013] Furthermore, the connecting assembly includes a baffle and a rotating block, the first clamp and the second clamp are connected to the baffle, and the rotating block is restricted between the baffle and the first clamp and the second clamp, and the first nut is connected to the rotating block.

[0014] Furthermore, the connecting assembly also includes a third nut, which secures the baffle to the first clamp and the second clamp respectively.

[0015] The beneficial effects of this utility model are:

[0016] (1) The deep-sea cylindrical object salvage clamp proposed in this utility model uses a threaded rod to rotate. With the cooperation of the first nut, the distance between the two connecting components changes, and the distance between the top of the first clamp and the second clamp is further changed, so that the clamp structure can complete clamping and releasing, and can realize the salvage of cylindrical objects of different sizes.

[0017] (2) The deep-sea cylindrical object salvage clamp proposed in this utility model uses a main beam to connect multiple clamp structures, which can clamp cylinders of different lengths. At the same time, it can ensure that the object is subjected to uniform force during the clamping and lifting process, and prevent deformation or slippage caused by local stress concentration.

[0018] (3) Compared with the traditional manual binding or temporary welding fixing method, the deep-sea cylindrical object salvage clamp proposed in this utility model can achieve rapid deployment and automatic locking, greatly shorten the underwater operation time, and reduce the difficulty of operation for divers or submersibles.

[0022] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Please refer to Figures 1-2 This utility model proposes a deep-sea cylindrical object salvage clamp, including at least one clamp structure. The clamp structure includes a first clamp 1, a second clamp 2, and an adjustment component. The first clamp 1 and the second clamp 2 are rotatably connected. An adjustment mechanism connecting the first clamp 1 and the second clamp 2 is provided at the top of the clamp structure. The adjustment mechanism includes a connecting component, a first nut 11, and a threaded rod 6. The connecting component is fixed on the first clamp 1 and the second clamp 2. The first nut 11 is provided on the connecting component of the first clamp 1 and the second clamp 2. The threaded rod 6 rotates to change the distance between the connecting component on the first clamp 1 and the connecting component on the second clamp 2, thereby adjusting the opening and closing of the first clamp 1 and the second clamp 2.

[0025] In a specific embodiment, the first clamp 1 and the second clamp 2 are movably connected to form a rotatable X-structure. The upper ends of the first clamp 1 and the second clamp 2 are connected to two different first nuts 11 through a connecting component. One of the two first nuts 11 can only rotate around the threaded rod 6, while the other is engaged with the thread on the threaded rod 6. When the threaded rod 6 rotates counterclockwise or clockwise, the distance between the two first nuts 11 will change, thereby changing the distance between the top ends of the first clamp 1 and the second clamp 2, so as to realize the clamping and loosening of the clamp structure.

[0026] Furthermore, it also includes a connecting plate 7, which is connected to the fixture structure.

[0027] In a specific embodiment, one end of the connecting plate 7 is fixed to the adjustable hanging chain 12 with a clamp structure so that the adjustment mechanism can adjust the clamp structure.

[0028] Furthermore, it also includes a first screw 9 and a second nut 10, the first screw 9 passing through the first clamp 1, the second clamp 2 and the connecting plate 7, and connected to the second nut 10.

[0029] In a specific embodiment, the connecting plate 7 is connected to the first screw 9, and the first clamp 1 and the second clamp 2 can rotate around the first screw 9 under the constraint of the first screw 9.

[0030] Furthermore, a first hook point 8 is provided on the top of the connecting plate 7.

[0031] In a specific implementation, the first hook point 8 is used to connect the adjustable lifting chain 12. Each clamp structure is connected to the main beam 13 through the connecting plate 7 and the first hook point 8 on the connecting plate 7, so as to facilitate the retrieval of cylindrical objects of different lengths.

[0032] Furthermore, it also includes a main beam 13, at least one adjustable suspension chain 12 is provided at the bottom of the main beam 13, one end of the adjustable suspension chain 12 is connected to the first hook point 8, and the other end is connected to the main beam 13.

[0033] In a specific implementation: the adjustable chain 12 can be adjusted in length, and the main beam 13 is connected to each clamping structure through multiple adjustable chains 12, so that different numbers of clamping structures can be selected according to actual needs to clamp cylinders of different lengths. At the same time, it can ensure that the object is subjected to uniform force during the clamping and lifting process, and prevent deformation or slippage caused by local stress concentration.

[0034] Furthermore, a second hook point 14 is provided at the top of the main beam 13.

[0035] In a specific implementation, the second hook point 14 is used to connect a diving operation tool. The diving operation tool is connected to the second hook point 14 to realize seabed operation.

[0036] Furthermore, the connecting assembly includes a baffle 4 and a rotating block 3. The first clamp 1 and the second clamp 2 are connected to the baffle 4, thereby restricting the rotating block 3 between the baffle 4 and the first clamp 1 and the second clamp 2. The first nut 11 is connected to the rotating block 3.

[0037] In a specific embodiment, the baffle 4 is fixed on the fixture and the rotating block 3 is restricted between the baffle 4 and the fixture structure. The rotating block 3 can rotate around the fixture structure. Since the rotating block 3 is connected to the fixture, the threaded rod 6 can rotate and change the distance between the two first nuts 11, thereby changing the clamping and loosening of the fixture.

[0038] Furthermore, the connecting assembly also includes a third nut 5, which fixes the baffle 4 to the first clamp 1 and the second clamp 2 respectively.

[0039] In a specific embodiment, the third nut 5 fixes the baffle 4 onto the clamp to restrict the rotating block 3.

[0040] In summary, the specific usage includes the following steps: After inspecting the clamp, a submersible carries the clamp down to the surface. The submersible uses a robotic arm to fix the clamp onto the cylindrical target, and then another robotic arm tightens the threaded rod 6 to clamp the target object. Finally, the submersible works with the mother ship to lift the object. The mother ship releases a hoisting cable to the vicinity of the target, and the hoisting cable carried by the submersible is fixed to the clamp. Finally, the mother ship lifts the object and completes the entire salvage operation of the cylindrical object.

[0041] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
