Description

Technical Field

[0001] This utility model relates to the field of underwater salvage technology, specifically to an underwater salvage device. Background Technology

[0002] There are many underwater devices used in the wastewater treatment industry, such as wastewater pumps, agitators, and mixers. Typically, underwater equipment is fixed to a support frame and secured with a chain.

[0003] A salvage device for underwater equipment, disclosed in CN220281636U, includes a salvage hook, an underwater camera with a strong light source, and a hoist chain. The salvage hook includes a salvage hook and a salvage rod. The salvage hook is used to hook the lifting ring of the underwater equipment, while the salvage rod is designed to facilitate the operator to move the salvage hook to the vicinity of the underwater equipment.

[0004] The above-mentioned device requires the retrieval hook to be attached to the lifting ring of the underwater equipment during use. However, when the lifting ring is directly above the underwater equipment, the retrieval hook cannot be properly inserted into the lifting ring. At this time, the operator needs to constantly move the position to tilt the retrieval rod to tilt the retrieval hook, align the hook with the lifting ring, and then move the retrieval hook horizontally to hook it into the lifting ring. This is inconvenient to operate. Therefore, we propose an underwater retrieval device. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an underwater salvage device that uses a fixed rope to drive the salvage hook to rotate on the outside of the salvage rod, thereby adjusting the hook to a position where it can be inserted into the lifting ring of the underwater equipment.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problem that the retrieval hook is not easy to insert into the hoisting ring located directly above the underwater equipment through the following technical solution.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An underwater salvage device includes a salvage rod and a salvage hook, a mounting base and auxiliary components. A hoist chain is fixedly mounted on the outside of the salvage hook, and a fixing rod is fixedly mounted on the top of the salvage hook. The mounting base is fixedly mounted on the bottom of the salvage rod, and a rotating cylinder is rotatably mounted inside the mounting base. The fixing rod is fixedly mounted on the outside of the rotating cylinder, and a fixing shaft is fixedly mounted on the outside of the rotating cylinder. A fixing rope is fixedly mounted on the fixing shaft. The auxiliary components are located on the outside of the salvage rod and are used to observe information at the salvage hook.

[0009] Preferably, a fixing ring is fixed on the outside of the retrieval rod, and a fixing rope passes through the inside of the fixing ring.

[0010] Preferably, the mounting base is located on the outer bottom of the retrieval rod and is perpendicular to the retrieval rod.

[0011] Preferably, the fixing rod is arranged perpendicularly to the fixing shaft on the outside of the rotating drum.

[0012] Preferably, the auxiliary components include an underwater camera, with a searchlight fixedly mounted on the bottom of the underwater camera, and a mounting platform fixedly mounted on the bottom of the salvage pole. The mounting platform and the mounting base are symmetrically arranged, and the underwater camera is fixedly mounted on the outside of the mounting platform.

[0013] Preferably, the outer side of the mounting platform is provided with an inclined surface, the mounting platform is located on the inclined surface, and the inclined surface points towards the retrieval hook.

[0014] Preferably, the fixing rope is a steel wire rope.

[0015] Preferably, the inside of the retrieval hook is provided with a baffle, and a fixed frame is fixedly provided at the top of the inside of the retrieval hook. A fixed cylinder is rotatably provided inside the fixed frame, and the top of the baffle is fixedly connected to the fixed cylinder.

[0016] Preferably, symmetrically distributed torsion springs are fixed inside the fixing frame. The torsion springs are located inside the fixing cylinder, and the end of the torsion spring away from the fixing frame is fixed to the fixing cylinder.

[0017] Preferably, the openings of the fixed shaft and the retrieval hook are located on both sides of the fixed rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model rotatably mounts the retrieval hook on the outside of the retrieval rod. When it is necessary to tilt the retrieval hook, simply pull the fixed rope, which drives the retrieval hook to rotate within the mounting base via the fixed shaft. This allows the hook to be rotated to a position where it can pass through the lifting ring of the underwater equipment. There is no need to tilt the retrieval rod to tilt the retrieval hook, making the operation convenient.

[0020] By setting a fixing ring on the outside of the bottom of the retrieval rod to secure the rope, the direction of the fixing rope can be adjusted using the fixing ring, thereby allowing the retrieval hook to rotate at a greater angle through the fixing rope. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0030] Please see Figure 1 - Figure 6 An underwater salvage device includes a salvage rod 1 and a salvage hook 2, a mounting base 4 and auxiliary components 9. A hoist chain 3 is fixedly installed on the outside of the salvage hook 2, and a fixing rod 5 is fixedly installed on the top of the salvage hook 2. The mounting base 4 is fixedly installed at the bottom of the salvage rod 1. A rotating cylinder 6 is rotatably installed inside the mounting base 4. The fixing rod 5 is fixedly installed on the outside of the rotating cylinder 6. A fixing shaft 7 is fixedly installed on the outside of the rotating cylinder 6. A fixing rope 8 is fixedly installed on the fixing shaft 7. By pulling the fixing rope 8, the operator on shore can rotate the salvage hook 2 inside the mounting base 4, thereby adjusting the orientation of the salvage hook 2 and rotating the hook of the salvage hook 2 to a position that is convenient for passing through the lifting ring of the underwater equipment.

[0031] The auxiliary component 9 is located on the outside of the salvage rod 1 and is used to observe the information at the salvage hook 2. The information at the salvage hook 2 is observed in real time by the underwater camera 11, which facilitates the movement of the salvage hook 2 to the underwater equipment.

[0032] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0033] Please see Figure 1 - Figure 6By rotating the salvage hook 2 to the outside of the salvage rod 1, when it is necessary to tilt the salvage hook 2, simply pull the fixing rope 8, and the fixing shaft 7 will drive the salvage hook 2 to rotate within the mounting base 4, so that the hook of the salvage hook 2 can be rotated to a position where it can pass through the lifting ring of the underwater equipment. There is no need to tilt the salvage rod 1 to tilt the salvage hook 2, which is convenient to operate.

[0034] The retrieval rod 1 is fixedly provided with a fixing ring 10 on the outside, and the fixing rope 8 passes through the inside of the fixing ring 10. The fixing ring 10 is located near the mounting base 4. By using the fixing ring 10 to change the trajectory of the fixing rope 8, the end of the fixing rope 8 connected to the fixing shaft 7 is brought closer to the mounting base 4. Thus, when the fixing shaft 7 and the rotating drum 6 are rotated by the fixing rope 8, the rotation range of the rotating drum 6 can be increased, thereby increasing the rotation range of the retrieval hook 2 on the outside of the rotating drum 6.

[0035] In addition, the mounting base 4 is located on the bottom outer side of the retrieval rod 1 and is perpendicular to the retrieval rod 1. The fixing rod 5 and the fixing shaft 7 are perpendicularly arranged on the outer side of the rotating drum 6. The openings of the fixing shaft 7 and the retrieval hook 2 are located on both sides of the fixing rod 5, which makes it convenient to rotate the retrieval hook 2, which is in a vertical state, to a horizontal state.

[0036] It is worth noting that the auxiliary component 9 includes an underwater camera 11, with a searchlight fixedly mounted on the bottom of the underwater camera 11, and a mounting platform 12 fixedly mounted on the bottom of the salvage rod 1. The mounting platform 12 and the mounting base 4 are symmetrically arranged. The underwater camera 11 is fixedly mounted on the outside of the mounting platform 12, and an inclined surface 13 is provided on the outside of the mounting platform 12. The mounting platform 12 is located on the inclined surface 13, which points towards the salvage hook 2. When the salvage rod 1 is submerged underwater, the searchlight illuminates the area in front of the underwater camera 11. The inclined surface 13 allows the underwater camera 11 to transmit information from the salvage hook 2 to the shore in real time, making it convenient for operators to move the salvage hook 2 to the underwater equipment.

[0037] The principle behind adjusting the position of the retrieval hook 2 is explained below:

[0038] First, the salvage hook 2 is lowered into the water using the salvage rod 1. The searchlight is turned on to explore the underwater environment and transmit the underwater information to the operators on the shore in real time through the underwater camera 11. The operators then move the salvage hook 2 to the underwater equipment.

[0039] The operator observes the position of the lifting ring of the underwater equipment through the underwater camera 11, and then pulls the fixing rope 8. The fixing rope 8 pulls the fixing shaft 7 through the fixing ring 10. The fixing shaft 7 drives the rotating drum 6 to rotate in the mounting base 4, thereby driving the salvage hook 2 to rotate with the rotating drum 6 through the fixing rod 5, and rotating the hook of the salvage hook 2 to a position where it can be inserted into the lifting ring.

[0040] The operator uses the salvage rod 1 to guide the salvage hook 2 into the hoisting ring, and then uses the hoist chain 3 to salvage the underwater equipment onto the shore via the salvage hook 2.

[0041] In this technical solution, the fixing rope 8 is a steel wire rope, which can improve the strength and wear resistance of the fixing rope 8.

[0042] In this technical solution, such as Figure 5 and Figure 6 As shown, a baffle 14 is provided on the inner side of the fishing hook 2, and a fixed frame 15 is fixedly provided on the top of the inner side of the fishing hook 2. A fixed cylinder 16 is rotatably provided inside the fixed frame 15. The top of the baffle 14 is fixedly connected to the fixed cylinder 16. Symmetrically distributed torsion springs 17 are fixedly provided inside the fixed frame 15. The torsion springs 17 are located inside the fixed cylinder 16, and the end of the torsion spring 17 away from the fixed frame 15 is fixed to the fixed cylinder 16.

[0043] After the hook of the salvage hook 2 is inserted into the lifting ring of the underwater equipment, the baffle 14 rotates with the fixed cylinder 16 under the action of the torsion spring 17 until the baffle 14 abuts against the inside of the salvage hook 2. The baffle 14 seals the opening of the salvage hook 2, which can prevent it from coming off the hook.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
