Description

Technical Field

[0001] This utility model relates to the field of nautical chart exploration technology, and in particular to a positioning mechanism for lowering marine exploration nodes. Background Technology

[0002] The development of offshore oil and gas resources places higher demands on marine exploration technology. Conventional marine seismic exploration methods, such as towed cables and submarine cables, have certain limitations. Towed cables are greatly affected by wind, waves, and ocean currents, leading to inaccurate exploration results; during the laying of submarine cables, ocean currents, tides, ship speed, and the settling speed of the detectors can affect the accuracy of detector placement, easily causing deviations in exploration data. Therefore, more precise and efficient marine exploration node placement technology is needed, which requires mechanical placement. In marine exploration node placement technology, mechanical placement is the core method of accurately transporting exploration nodes from the sea surface (or ship deck) to the target location on the seabed through the coordinated action of mechanical components such as gears, chains, winches, robotic arms, and guide rails. Its core functions revolve around three dimensions: "safe carrying capacity, precise control, and environmental adaptability," directly determining the efficiency of the placement operation. Therefore, a positioning mechanism for marine exploration node placement is needed.

[0003] In existing technologies, most positioning mechanisms used for lowering marine exploration nodes locate the ropes by direct pressure. This causes significant friction on the outer surface of the ropes, directly damaging them. Furthermore, the installation and securing of the ropes require manual intervention, resulting in a significant waste of manpower. Additionally, during retrieval, the presence of silt and dirt on the ropes after positioning in the sea can hinder the recovery of the locator. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for lowering marine exploration nodes, addressing the issues raised in the background section. Currently, most existing positioning mechanisms for lowering marine exploration nodes rely on direct pressure to position the rope, causing significant friction on the rope's outer surface and resulting in direct damage. Furthermore, the installation and securing of the rope requires manual intervention, leading to substantial waste of manpower. Additionally, during retrieval, the presence of silt and dirt on the rope after positioning in the sea hinders the recovery of the locator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for lowering marine exploration nodes, comprising a connecting chain, a chain frame body disposed on the lower surface of the connecting chain, rotating wheels disposed on both sides of the chain frame body, and further comprising:

[0006] A connecting shaft is provided; a side fixing plate is fixedly connected to the outer surface of the chain frame; a set of speed-regulating and decelerating motors are provided on the outer surface of the side fixing plate; and a connecting shaft is inserted into the interior of the rotating wheel.

[0007] A push plate is provided, with a chain connecting plate fixedly connected to one end of the connecting chain, an inner plate fixedly connected to the inner surface of the chain connecting plate, a linear guide rail fixedly connected to the upper surface of the inner plate, a fixed shaft connected inside the inner plate, and a push plate fixedly connected to the outer surface of the fixed shaft.

[0008] Preferably, the outer surface of the push plate is provided with a first electric sliding groove, the inner surface of the first electric sliding groove is provided with a sliding block, and the inner sides of the upper and lower sides of the sliding block are provided with a first magnetic block.

[0009] Preferably, the sliding block has multiple sets of rotating shafts inside, and two sets of second electric sliding grooves are formed on the outer surface of the sliding block.

[0010] Preferably, a first tool ring is provided on the left side of the sliding block, and a second tool ring is provided on the right side of the sliding block. The first tool ring and the second tool ring are rotatably connected to the second electric sliding grooves on the left and right sides, respectively.

[0011] Preferably, the first tool ring is provided with a first telescopic rod inside, one end of the first telescopic rod is fixedly connected to a clamping member, and the two ends of the first tool ring are fixedly provided with second magnetic blocks.

[0012] Preferably, a second telescopic rod is provided on the inner surface of the second tool ring, a brush head is fixedly connected to one end of the second telescopic rod, and a second magnetic block is fixedly provided at both ends of the second tool ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses a sliding block, a rotating shaft, a first magnetic block, a second magnetic block, a first tool ring, a second tool ring, and a first telescopic rod. When the rotating shaft in the sliding block contacts the rope, the first magnetic block attracts the sliding block. At the same time, the first and second tool rings are also attracted by the second magnetic block. When the rope slides to the appropriate position, the first telescopic rod is activated to move the clamping device downwards when positioning is required. After the rope is clamped, the second electric slide rail rotates, causing the first tool ring to rotate as a whole, making the clamping more stable. This eliminates the need for manual intervention, allowing the rope to be clamped and positioned directly.

[0015] 2. This application is equipped with a second telescopic rod, a clamping component, a brush head, a second tool ring, and a second electric slide rail. When the second telescopic rod is retracted, the clamping component is retracted and engages in clamping. Then, the second telescopic rod extends so that the brush head contacts the rope. At this time, the second tool ring rotates in the second electric slide rail, causing the brush head to brush off the dirt on the surface of the rope, thereby reducing the difficulty of rope retrieval.

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] The outer surface of the push plate 11 is provided with a first electric slide groove 12, and the inner surface of the first electric slide groove 12 is provided with a sliding block 13. The inner sides of the upper and lower sides of the sliding block 13 are provided with a first magnetic block 14. The sliding block 13 is divided into left and right sides. The function of the first magnetic block 14 is to attract the sliding blocks 13 on both sides. The sliding blocks 13 will move in the first electric slide groove 12 to realize opening, closing and shutting.

[0025] The sliding block 13 has multiple sets of rotating shafts 15 inside, and two sets of second electric sliding grooves 16 are opened on the outer surface of the sliding block 13. The rotating shafts 15 will reduce the friction of the rope. A first tool ring 17 is provided on the left side of the sliding block 13, and a second tool ring 20 is provided on the right side of the sliding block 13. The first tool ring 17 and the second tool ring 20 are rotatably connected to the second electric sliding grooves 16 on the left and right sides respectively. The first tool ring 17 will rotate in the second electric sliding groove 16 on the left side, and similarly, the second tool ring 20 will rotate in the second electric sliding groove 16 on the right side.

[0026] The first tool ring 17 has a first telescopic rod 18 inside. One end of the first telescopic rod 18 is fixedly connected to a clamping member 19. The two ends of the first tool ring 17 are fixedly provided with second magnetic blocks 23. The first telescopic rod 18 will drive the clamping member 19 to clamp, thereby clamping the rope. The first tool ring 17 is divided into two groups, which are attracted by the second magnetic blocks 23.

[0027] The inner surface of the second tool ring 20 is provided with a second telescopic rod 21. One end of the second telescopic rod 21 is fixedly connected to a brush head 22. The two ends of the second tool ring 20 are fixedly provided with second magnetic blocks 23. The second telescopic rod 21 is extended and retracted, so that the brush head 22 can brush away dirt from the outer surface of the rope. The second tool ring 20 is divided into two groups, which are attracted by the second magnetic blocks 23.

[0028] Working principle: In existing technologies, most positioning mechanisms for lowering marine exploration nodes locate the rope by direct pressure. This causes significant friction on the outer surface of the rope, directly damaging it. Furthermore, the installation and securing of the rope requires manual intervention, resulting in substantial waste of manpower. Additionally, during retrieval, silt and dirt on the rope after positioning in the sea can hinder the recovery of the locator. This device addresses these issues.

[0029] First, a side fixing plate 4 is fixedly connected to the outer side of the chain frame 2. A speed-regulating reduction motor 5 is set on the outer surface of the side fixing plate 4. Then, the speed-regulating reduction motor 5 will rotate, driving the connecting shaft 6 to rotate. The connecting shaft 6 will drive the rotating wheel 3 to rotate. When the rotating wheel 3 rotates, it will drive the connecting chain 1 to move. Chain connecting plates 7 are fixedly connected to both ends of the connecting chain 1. The chain connecting plates 7 will drive the inner side plate 8 to move. When the inner side plate 8 moves, it will move left and right on the linear guide rail 9. When the inner side plate 8 moves, it will drive the fixed shaft 10 and the push plate 11 to move. When it moves to the appropriate position.

[0030] The sliding block 13 in the first electric slide rail 12 will be driven to move, causing the sliding blocks 13 on both sides to move towards the center, so that the rotating shaft 15 in the sliding block 13 contacts the rope. The function of the rotating shaft 15 is to reduce the friction of the rope and to position the rope to prevent the rope and the positioner from tilting. Then, it is attracted by the first magnetic block 14. At this time, the first tool ring 17 and the second tool ring 20 will also be attracted by the second magnetic block 23. When the rope slides to the appropriate position, when positioning is required, the first telescopic rod 18 is activated to drive the clamping member 19 to move downward. After the rope is clamped, the second electric slide rail 16 will rotate, causing the first tool ring 17 to rotate as a whole, making the clamping more stable. In this way, no manual intervention is required to directly clamp the rope and position it to the required position.

[0031] When the rope is retrieved, the second telescopic rod 21 is retrieved to retrieve the clamping part 19 and make contact with the clamp. Then the second telescopic rod 21 is extended so that the brush head 22 contacts the rope. At this time, the second tool ring 20 will rotate in the second electric slide 16, so that the brush head 22 brushes off the dirt on the surface of the rope, thereby reducing the difficulty of rope retrieval.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
