A fixing clamp structure for a submarine cable

Abstract

The application relates to the technical field of cable clamp and discloses a fixing clamp structure of a submarine cable, which comprises two groups of symmetrically-distributed mounting supports, and horizontal displacement driving mechanisms are symmetrically arranged on the sides, away from each other, of the two groups of mounting supports. The fixing clamp structure of the submarine cable is subjected to the disturbance effect of sea waves through the horizontal displacement driving mechanisms, thereby generating driving force to drive the whole cleaning mechanism to displace on the outside of the cable body. Through the flowing effect of water flow during the displacement of the cleaning mechanism, the whole cleaning ring is driven to rotate, thereby driving the cleaning scraper to rotate to rotateally clean marine organisms attached to the outside of the cable body. Meanwhile, the magnetic field of the cutting conversion unit is cut and converted into electric current through the following rotation of the magnetic induction coil. The electric current is conducted to the position of the cleaning scraper through the conversion unit, thereby electrically stimulating the stubbornly-attached marine organisms to make them free from the attachment state with the cable body, so that the cleaning function of the surface of the cable body is realized.

[0042] Example 1

[0043] like Figures 1 to 16As shown, a fixing clamp structure for a submarine cable includes two symmetrically distributed mounting brackets 100. Each mounting bracket 100 has a long through hole 102 in its middle. Displacement through holes 104 are symmetrically arranged at both ends of each mounting bracket 100. Positioning protrusions 103 are provided at the bottom of the inner side of each displacement through hole 104. Lateral displacement driving mechanisms 400 are symmetrically arranged on the side of each mounting bracket 100 that is far apart from each other. The lateral displacement driving mechanism 400 includes a driving impeller 401 disposed on the outer side of each mounting bracket 100. Each set of mounting brackets 100 has symmetrically arranged driving impellers 401 at both ends. The central shaft of each driving impeller 401 passes through the displacement through hole 104 and extends to the inner side of the mounting bracket 100. A first gear 402 is provided at the other end of the central shaft of each driving impeller 401. A connecting rod 404 is provided between the two sets of central shafts located inside each set of mounting brackets 100. A positioning protrusion 103 is symmetrically arranged at the bottom of the connecting rod 404. The lever 403 and the positioning protrusion 103 limit the central axis of the drive impeller 401. The drive shaft 409 is symmetrically arranged on the outer side of the mounting bracket 100 at both ends of the long through hole 102. The drive shaft 409 is provided with a rope wheel 405 at one end of the drive shaft 409 on the outer side of the mounting bracket 100. The traction rope 406 is wound between the two sets of rope wheels 405. The middle of the traction rope 406 is provided with a slider 407. The slider 407 slides horizontally against the outer side of the mounting bracket 100. The end of the drive shaft 409 near the inner side of the mounting bracket 100 is provided with a second gear 408. When a set of second gears 408 meshes with the corresponding first gear 402, the first gear 402 at the other end of the connecting rod 404 separates from the corresponding second gear 408. When the drive impellers 401 at both ends of the set of mounting brackets 100 are impacted by seawater in the same direction, the rotation directions of the two are opposite.

[0044] Two sets of lateral displacement drive mechanisms 400 are provided with a cleaning mechanism 300 on their respective sides, and two sets of mounting brackets 100 are provided with a common clamp on their respective sides to hold the cable body 200. The cable body 200 passes through both ends of the cleaning mechanism 300. The bottom of the mounting bracket 100 is fixedly connected to the seabed. The lateral displacement drive mechanism 400 is powered by the impact force of seawater to drive the cleaning mechanism 300 to move back to its original position on the outside of the cable body 200. The cleaning mechanism 300 is used to clean the outside of the cable body 200.

[0045] The cleaning mechanism 300 includes connecting shafts 304 disposed inside two sets of mounting brackets 100. One end of each connecting shaft 304 passes through a long through hole 102 and is fixedly connected to a slider 407. The ends of the two connecting shafts 304 that are close to each other are provided with mounting sleeves 301, which are fitted onto the outside of the cable body 200. Squeezing blocks 303 are symmetrically arranged at both ends of the outer side of the mounting sleeve 301, corresponding to the actuating lever 403. A roller cavity 314 is provided in the middle of the inner side of the mounting sleeve 301. A supporting roller 320 is installed inside the roller cavity 314, and a corresponding support roller 320 is provided on the inner side of the supporting roller 320. The cable body 200 has rolling balls on its outer side. The mounting sleeve 301 has symmetrically arranged cleaning rotating cavities 321 at both ends. Cleaning rings 309 are rolled inside the cleaning rotating cavities 321. Several sets of worm gear blades 322 are evenly distributed on the outer side of the cleaning rings 309. Several sets of cleaning scrapers 308 are evenly distributed at the end of the cleaning rings 309 away from the mounting sleeve 301. The cleaning scrapers 308 have an arc-shaped structure, and their bottoms are attached to the outer side of the cable body 200. Electromagnetic cavities 313, communicating with the cleaning rotating cavities 321, are symmetrically arranged in the middle of the mounting sleeve 301. The top of the inner wall of the electromagnetic cavity 313 is provided with… The permanent magnet 306 has a transition ring 307 located on the inner side of the cleaning rotating cavity 321 near the electromagnetic cavity 313. A coil support ring 310 extending into the electromagnetic cavity 313 is located on the outer side of the transition ring 307 near the electromagnetic cavity 313. Magnetic coils 315 are evenly distributed on the outer side of the coil support ring 310, located inside the permanent magnet 306. When the magnetic coils 315 rotate with the coil support ring 310, they cut the magnetic field of the permanent magnet 306 and generate current. Several sets of limiting wedges 316 are evenly distributed on the transition ring 307 and the end near the cleaning ring 309. The cleaning ring 309 is evenly distributed on the end near the transition ring 307. There are the same number of mounting slots 318 as the limiting wedge 316. The inside of the mounting slot 318 is hinged to a movable wedge 317. The inner side of the movable wedge 317 is provided with a spring 319 that is fixedly connected to the mounting slot 318. The outer side of the movable wedge 317 is engaged with the limiting wedge 316 in one direction. Two sets of conversion units 305 are symmetrically arranged on the top of the mounting sleeve 301. The input end of the conversion unit 305 is electrically connected to the output end of the magnetic induction coil 315. The output end of the conversion unit 305 is provided with a wire 311. The output end of the wire 311 is provided with an electrode brush 312. The output end of the electrode brush 312 is in contact with the outer side of the cleaning ring 309.

[0046] Two sets of mounting brackets 100 are symmetrically provided with fixing plates 101 at both ends of one side of each other. The fixing plates 101 are clamped on the outside of the cable body 200, and the cleaning mechanism 300 is located between the two sets of fixing plates 101.

[0047] The process of using the fixing clamp structure for the submarine cable proposed in this embodiment is as follows: the outer side of the cable body 200 is fastened by the fixing clamp 101, and the mounting bracket 100 is fastened to the seabed, thereby completing the clamping, positioning and installation of the cable body 200.

[0048] When one side of a set of mounting brackets 100 is impacted by waves, a set of lateral displacement drive mechanisms 400 rotates, causing its central shaft to rotate, which in turn causes the first gear 402 to rotate. The rotation of the first gear 402 drives the second gear 408, which meshes with it, to rotate, thereby driving the rope wheel 405 at one end of the transmission shaft 409 to rotate. The rotation of the rope wheel 405 winds up the traction rope 406, causing the slider 407 to slide and displace on the outside of the mounting bracket 100, which in turn causes the mounting sleeve 301 connected to the connecting shaft 304 to move as a whole.

[0049] As the mounting sleeve 301 moves horizontally along the outer side of the cable body 200, the water flow during the movement of the mounting sleeve 301 creates a reverse impact force with the mounting sleeve 301. The water flow enters the interior of the cleaning rotating cavity 321, thereby generating an impact force on the worm gear blade 322. This causes the worm gear blade 322 to drive the cleaning ring 309 to rotate inside the cleaning rotating cavity 321. Furthermore, the cleaning ring 309 drives the cleaning scraper 308 to rotate on the outer side of the cable body 200. The rotation of the cleaning scraper 308 scrapes and cleans the marine organisms attached to the outer side of the cable body 200. At the same time, the arc-shaped structure design of the cleaning scraper 308 improves the cleaning effect on the surface of the cable body 200.

[0050] Furthermore, as the cleaning ring 309 rotates, it causes the movable wedge 317 to engage with the limiting wedge 316. At this time, the transition ring 307 connected to the limiting wedge 316 causes the coil support ring 310 to rotate. The rotation of the coil support ring 310 causes the magnetic coil 315 to rotate, so that the magnetic coil 315 rotates inside the electromagnetic cavity 313. As the magnetic coil 315 rotates, it cuts the magnetic field generated by the permanent magnet 306, thereby generating current inside the magnetic coil 315.

[0051] The current is introduced into the position of the electrode brush 312 through the conversion unit 305. The electrode brush 312 is in contact with the cleaning ring 309, thereby introducing the current into the position of the cleaning scraper 308, making the cleaning scraper 308 charged. During the cleaning process of the cleaning scraper 308 cleaning the marine organisms on the surface of the cable body 200, the stimulation of the current causes some marine organisms that are firmly attached to the surface of the cable body 200 to retract, thereby releasing their attachment to the cable body 200 and improving the cleaning effect on the marine organisms on the surface of the cable body 200.

[0052] As the mounting sleeve 301 moves as a whole, the pressing block 303 moves accordingly. When the mounting sleeve 301 moves to one end of the mounting bracket 100, the pressing block 303 presses the 403, which in turn drives the first gear 402 and the drive impeller 401 at both ends of the connecting rod 404 to move accordingly. This further causes the first gear 402 near one end of the mounting sleeve 301 to disengage from its corresponding second gear 408, while the first gear 402 at the other end engages with the second gear 408. This achieves the reverse switching function of the horizontal displacement power of the mounting sleeve 301, thereby causing the mounting sleeve 301 to reciprocate horizontally on the outside of the cable body 200.

[0053] The symmetrical structural design of the mounting sleeve 301 allows both ends of the mounting sleeve 301 to clean the surface of the cable body 200 during the retraction process, further improving the cleaning effect on the surface of the cable body 200.

[0054] When seawater impacts another set of mounting brackets 100 in the opposite direction, the lateral displacement drive mechanism 400 on one side of the mounting bracket 100 works on the same principle as above, thereby driving the cleaning mechanism 300 to move outside the cable body 200 to achieve the cleaning function.

[0055] The specific implementation of this embodiment has been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
