Description

Technical Field

[0001] This utility model relates to the field of marine surveying technology, specifically to a cable safety fixing device for marine surveying vessels. Background Technology

[0002] As a crucial platform for marine resource exploration, hydrographic mapping, and seabed topography monitoring, the operational accuracy of oceanographic survey vessels directly depends on the stable deployment of various underwater equipment. The cable, serving as the core carrier connecting the vessel to the survey equipment (such as multibeam sonar and CTD salinity / temperature analyzers), bears multiple functions, including equipment suspension and positioning, power / data transmission, and emergency retrieval. In severe sea conditions (such as waves exceeding 3 meters in height) or fast-flowing areas, the cable must withstand dynamic loads ranging from hundreds of kilograms to several tons. If the winding roller accidentally detaches, causing the cable to slip, it can not only damage survey equipment worth millions of dollars but also potentially lead to major accidents such as vessel capsizing and casualties.

[0003] Traditional pawl locks rely on manual operation of the handle. When the ship is pitching, the operator has to work close to the high-speed rotating take-up roller, which can easily cause limb entanglement accidents. It is highly dangerous and has low reliability. Utility Model Content

[0004] This invention provides a safety fixing device for cables on marine survey vessels, which has the advantages of low risk and high reliability, thus solving the problems of high risk and low reliability of traditional manual fixing methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety fixing device for cables on marine survey vessels, comprising a base plate, a frame, a cable winding roller, a reducer, and a first motor. The base plate is mounted on a frame, and the cable winding roller is rotatably mounted on the frame.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figures 1-3 This utility model discloses a safety fixing device for a cable on a marine survey vessel, comprising a base plate 1, a frame 2, a cable winding roller 3, a reducer 4, and a first motor 5. The frame 2 is mounted on the base plate 1, and the cable winding roller 3 is rotatably mounted on the frame 2. One end of the cable winding roller 3 is connected to the reducer 4 mounted on one side of the frame 2. The first motor 5 is mounted on the reducer 4, and the output shaft of the first motor 5 is connected to the cable winding roller 3 via the reducer 4. A [unclear - possibly a device or mechanism] is mounted on the roller shaft of the cable winding roller 3 on the other side of the frame 2. A ratchet 6 is provided, and an anti-detachment bar 8 is provided above the ratchet 6. The middle part of the anti-detachment bar 8 is connected to the frame 2 through a hinge pin 9. One end of the anti-detachment bar 8 is equipped with a pawl 10 that works with the ratchet 6. An electric telescopic bar 11 is inclinedly provided between the anti-detachment bar 8 and the frame 2. The two ends of the electric telescopic bar 11 are respectively hinged to the frame 2 and the anti-detachment bar 8. An extension plate 12 is installed at the front of the frame 2. A cable cleaning assembly is installed on the extension plate 12. A crossbar 19 is installed above the frame 2. A cable dehydration structure 20 is installed in the middle of the crossbar 19.

[0020] Specifically, the cable cleaning assembly includes an upper roller shaft 13, a lower roller shaft 14, a variable diameter brush roller 15, an upper transmission gear 16, a lower transmission gear 17, and a second motor 18. The upper roller shaft 13 and the lower roller shaft 14 are rotatably mounted on the two side extension plates 12. A variable diameter brush roller 15 is mounted on both the upper roller shaft 13 and the lower roller shaft 14. An upper transmission gear 16 and a lower transmission gear 17 are respectively mounted on one end of the upper roller shaft 13 and one end of the lower roller shaft 14. The upper transmission gear 16 and the lower transmission gear 17 mesh. The upper transmission gear 16 is directly connected to the output shaft of the second motor 18 mounted on the extension plate 12.

[0021] In this embodiment, the cleaning assembly is mounted on the extension plate 12 and consists of an upper roller shaft 13, a lower roller shaft 14, and a variable diameter brush roller 15. The diameter of the brush roller decreases in a stepped manner from one side to the other. With the meshing transmission of the upper transmission gear 16 and the lower transmission gear 17 (driven by the second motor 18), it can adapt to various cable thicknesses. When the cable passes through, the bristles of the variable diameter brush roller 15 sweep away the mud, salt, or microorganisms attached to the surface in a rotating manner.

[0022] Specifically, the ratchet 6 is provided with an outer cover 7 that is fixedly connected to the frame 2.

[0023] In this embodiment, the outer cover 7 can protect the ratchet 6, prevent foreign objects from entering the ratchet 6 and causing it to get stuck and damaged, and also protect personnel from being injured by the ratchet 6.

[0024] Specifically, the diameter of the variable diameter brush roller 15 decreases in a stepped manner from one side to the other.

[0025] In this implementation plan, the stepped design ensures uniform contact pressure and avoids cleaning dead spots. This innovation solves the problem of uneven cleaning effect of traditional fixed brush rollers on cables of different diameters, reduces the risk of cable breakage due to corrosion or wear, and reduces maintenance frequency (such as eliminating the need for frequent brush replacement). In long-term marine operations, it can save more than 20% of operating costs and meet environmental protection requirements.

[0026] Specifically, the cable dewatering structure 20 includes a frame 21, a lower dewatering roller 22, an upper dewatering roller 23, a threaded rod 24, a handle 25, and a guide groove 26. The upper dewatering roller 23 and the lower dewatering roller 22 are respectively arranged inside the frame 21. The lower dewatering roller 22 is rotatably installed inside the frame 21. The roller frame of the upper dewatering roller 23 is rotatably connected to the bottom end of the threaded rod 24 threaded on the frame 21. The top end of the threaded rod 24 is equipped with a handle 25. The roller shafts at both ends of the upper dewatering roller 23 are slidably connected to the guide grooves 26 opened on the inner walls of both sides of the frame 21.

[0027] In this embodiment, the cable dewatering structure 20 is installed on the crossbar 19 above the frame 2 and consists of a frame 21, a lower dewatering roller 22, and an upper dewatering roller 23. The roller frame of the upper dewatering roller 23 is rotatably connected to the bottom end of the threaded rod 24. The user can rotate the handle 25 to control the threaded rod 24 to rise and fall, so that the upper dewatering roller 23 slides along the guide groove 26, thereby adjusting the gap with the lower dewatering roller 22 to match the cable thickness. When the wet cable passes through, the two rollers apply uniform pressure to squeeze out the water. This design avoids rust and mildew caused by seawater retention, extends the service life of the cable, reduces the weight of the cable (facilitating winding and transportation), improves the efficiency of the survey vessel operation, and reduces subsequent drying energy consumption, which is especially critical in humid marine environments.

[0028] The working principle and usage process of this utility model are as follows: When in use, the operator starts the first motor 5, which drives the cable winding roller 3 to rotate through the reducer 4, so that the cable after the operation of the marine survey vessel is wound onto the roller at a uniform speed.

[0029] When the winding is completed or when a sudden storm requires emergency locking, the electric telescopic rod 11 is retracted, and the anti-derailment rod 8 is pulled to rotate counterclockwise around the hinge pin 9, which causes the pawl 10 to engage with the tooth groove of the ratchet 6.

[0030] During the cable winding process, the second motor 18 drives the upper transmission gear 16 to drive the lower transmission gear 17, causing the upper and lower variable diameter brush rollers 15 to rotate in opposite directions. When the cable passes through the gap between the two, the stepped bristles adaptively wrap around the surface of the cable, scraping away mud, sand and marine organisms.

[0031] Finally, the wound-up wet cable is guided by the crossbar 19 into the cable dewatering structure 20. The operator rotates the handle 25 to adjust the threaded rod 24, causing the upper dewatering roller 23 to press down along the guide groove 26, forming a suitable gap with the fixed lower dewatering roller 22. As the cable passes through, the double rollers squeeze out the water.
