Description

Technical Field

[0001] This invention belongs to the field of wire and cable repair technology, and specifically relates to a submarine cable recycling and monitoring device. Background Technology

[0002] Chinese patent document CN112152137B discloses a device for detecting and automatically repairing damage to the outer sheath of electrical wires and cables. The device includes a main body with a fixed disc inside, and an electrolytic plate inside the fixed disc. The electrolytic plate inside the fixed disc ionizes air into positive and negative charges. Positive charges are then adsorbed onto the electrical wire and cable through ion exchange holes in the inlet pipe. If the outer sheath of the electrical wire and cable is intact, the positive charges cannot adhere due to its insulation effect. If the outer sheath is damaged, the positive charges will adhere to the copper wires inside the cable. Then, a motor in a lower rubber sleeve drives a brush to contact a friction plate, causing the outer wall of the rubber sleeve to become negatively charged. This attracts the positive charges, thereby drawing the damaged outer sheath of the electrical wire and cable closer, thus determining the location of the damage.

[0003] During the use of the aforementioned patent, the attachments on the surface of the wires and cables were not cleaned, and these attachments could affect the test results.

[0004] Chinese patent document CN211292613U discloses a wire damage detection device, including a mounting plate. A photoelectric detection device is fixedly connected to the top left side of the mounting plate, and a pad is fixedly connected to the top right side of the mounting plate. A fixing sleeve is provided on the top of the mounting plate, located on the left side of the pad. Sleeves are fixedly connected to the right side of the photoelectric detection device and the left side of the pad, and the sleeves fit onto the surface of the fixing sleeve. This solution uses a transmission mechanism to drive the fixing sleeve to rotate, and then the fixing sleeve and sleeves, through a cleaning mechanism, brush and clean the surface of the wire. This provides the advantage of cleaning the wire, solving the problem that existing photoelectric sensing devices lack a certain cleaning structure on their surface, leading to false alarms due to dust and lint on the wire surface during detection. This improves the practicality of the photoelectric sensing device to a certain extent, making it easier for users to operate.

[0005] During use, as the cleaning time increases, more dirt accumulates on the cleaned areas, reducing the cleaning effect and requiring manual cleaning. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a submarine cable recycling and monitoring device that can clean the surface of submarine cables without stopping the machine and self-clean after cleaning is completed, in order to address the shortcomings of the existing technology.

[0007] To achieve the objective of this invention, the following technical solution is adopted: a submarine cable recovery and monitoring device, comprising a base, a recovery component disposed above the base, a cleaning component disposed above the base, and a detection component disposed between the recovery component and the cleaning component for inspecting the damage to the submarine cable sheath.

[0008] The cleaning assembly includes two brush plates rotatably connected to the upper part of the base and located on both sides of the submarine cable, and a cleaning roller rotatably connected between the two brush plates to clean the brush plates; when one end of the brush plate covers the submarine cable, the other end covers the cleaning roller.

[0009] Above the base, between the cleaning component and the recycling component, are two clamping blocks located on both sides of the submarine cable, respectively; above the base, in the vertical direction, is a push rod that is slidably connected to the two clamping blocks, respectively; the downward movement of the push rod causes the two brush plates to rotate.

[0010] The recycling assembly includes a recycling disc rotatably connected to the upper part of the base for moving the submarine cable, and a motor fixedly connected to the base for driving the recycling disc to rotate; the recycling disc is drivenly connected to the cleaning roller, and the rotation of the recycling disc causes the push rod to slide up and down reciprocally.

[0011] As the push rod moves upward, one end of the brush plate covering the submarine cable brushes the moving submarine cable, while the other end covering the cleaning roller is cleaned by the rotation of the cleaning roller. The upward-moving push rod causes the submarine cable, which has finished brushing, to bend upward.

[0012] As the push rod moves downward, the two clamping blocks move closer to each other to prevent the submarine cable from moving. The brush plate rotates, and the end that has finished brushing moves to cover the cleaning roller. The end that has finished cleaning moves to cover the submarine cable. The rotation of the recovery disc recovers the submarine cable that is bent upward.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is a submarine cable recycling device with detection function, which can check the degree of damage to the insulation sheath of the submarine cable during the recycling process. It can also clean the surface of the submarine cable before detection to remove the attached substances. At the same time, the cleaning is driven by a mechanical structure during the recycling process, without the need to set up additional electrical components for the cleaning process. The motor runs continuously throughout the entire use process without stopping the cleaning, thus improving efficiency.

[0014] Furthermore: First, the present invention can automatically replace the bristles and automatically clean the bristles, achieving a cycle without the need for manual cleaning of the cleaned bristles; specifically, the present invention uses a brush plate with bristles at both ends. When the bristles at one end brush the surface of the submarine cable, the bristles at the other end are rubbed and cleaned by the cleaning roller to remove dirt. After cleaning a certain length of the submarine cable, the brush plate rotates to switch, so that the bristles that have finished cleaning the submarine cable can clean the submarine cable, and the bristles that have finished brushing the submarine cable are rubbed and cleaned by the cleaning roller.

[0015] Secondly, this invention enables the brush plate to rotate without stopping the machine. When the brush plate rotates, the feeding of the submarine cable is stopped, allowing the remaining section of the submarine cable to be recovered. During the next cleaning cycle, the remaining submarine cable is replenished. Specifically, this invention uses a push rod. When the push rod moves upward, the brush plate cleans the submarine cable, causing it to bend upward and be retained. When the push rod moves downward, a clamping block prevents the transport of unwashed submarine cable. The brush plate rotates to replace the bristles, and the remaining submarine cable is recovered, preventing the recovery component from jamming.

[0016] Third, this invention incorporates a synchronization frame that adjusts the frequency of brush rotation based on the amount of submarine cable on the recovery tray, ensuring that the length of submarine cable cleaned is equal each time the brush is replaced. A friction wheel is positioned between the synchronization frame and the brush. As the synchronization frame is moved by the thickened cable, the friction wheel moves away from the center of the recovery tray. Compared to one rotation of the recovery tray without submarine cable, the recovered cable is longer, and the friction wheel sweeps a longer circumference, resulting in more rotations and more frequent brush switching. This ensures that the length of submarine cable cleaned is equal each time the brush is replaced. Attached Figure Description

[0025] according to Figures 1 to 9 As shown, the submarine cable recycling and monitoring device described in this embodiment includes a base 1, a recycling component 2 disposed above the base 1, a cleaning component 5 disposed above the base 1, and a detection component 3 disposed between the recycling component 2 and the cleaning component 5 for checking the damage to the submarine cable sheath.

[0026] The cleaning assembly 5 includes two brush plates 52 rotatably connected to the upper part of the base 1 and located on both sides of the submarine cable, and a cleaning roller 54 rotatably connected between the two brush plates 52 to clean the brush plates 52; when one end of the brush plate 52 covers the submarine cable, the other end covers the cleaning roller 54; both ends of the brush plate 52 are fixedly connected to bristles 521 capable of scrubbing the surface of the submarine cable.

[0027] Above the base 1, between the cleaning component 5 and the recycling component 2, are two clamping blocks 48 respectively located on both sides of the submarine cable; above the base 1, a push rod 41 is slidably connected in the vertical direction and is drivenly connected to the two clamping blocks 48 respectively; the downward movement of the push rod 41 drives the two brush plates 52 to rotate; a push wheel 411 for placing the submarine cable is rotatably connected to the push rod 41.

[0028] The recycling assembly 2 includes a recycling disc 21 rotatably connected to the upper part of the base 1 for moving the submarine cable, and a motor 26 fixedly connected to the base 1 for driving the recycling disc 21 to rotate; the recycling disc 21 is connected to the cleaning roller 54 in a transmission connection, and the rotation of the recycling disc 21 drives the push rod 41 to slide up and down reciprocally.

[0029] As the push rod 41 moves upward, one end of the brush plate 52 covering the submarine cable brushes the moving submarine cable, while the other end covering the cleaning roller 54 is cleaned by the rotation of the cleaning roller 54. The upward-moving push rod 41 causes the submarine cable that has finished brushing to bend upward, and the bent submarine cable is located between the clamping block 48 and the recycling component 2.

[0030] As the push rod 41 moves downward, the two clamping blocks 48 move closer to each other to prevent the submarine cable from moving. The brush plate 52 rotates, and the end that has finished brushing moves to cover the cleaning roller 54. The end that has finished cleaning moves to cover the submarine cable. The rotation of the recovery disc 21 recovers the submarine cable that is bent upward.

[0031] The detection component 3 is equipped with a camera, which can inspect the submarine cables passing through the detection component 3, thereby determining where the cable sheath is damaged.

[0032] The cleaning assembly 5 also includes a cleaning frame 51 fixedly connected to the upper end of the base 1; the upper end of the cleaning frame 51 has fixed shafts 511 formed on both sides of the submarine cable, which are rotatably connected to the corresponding brush plates 52; the middle of the brush plate 52 has a rotating sleeve 525 formed, which is rotatably connected to the fixed shaft 511; the outer wall of the fixed shaft 511 has two centrally symmetrically arranged and interconnected combined sliding grooves; the combined sliding groove includes a straight sliding groove 514 arranged along the axial direction of the fixed shaft 511, a smooth groove 513 arranged along the circumference of the fixed shaft 511, and an inclined sliding groove 515 arranged at an angle; one end of the smooth groove 513 is connected to the middle of the straight sliding groove 514, the other end of the smooth groove 513 is connected to the end of the inclined sliding groove 515 near the other brush plate 52, and the end of the inclined sliding groove 515 away from the other brush plate 52 is connected to the end of the straight sliding groove 514 away from the other brush plate 52.

[0033] The inner wall of the rotating sleeve 525 is formed with a brush plate slide column 522 that is slidably connected to the combined slide groove; the cleaning assembly 5 also includes a drive shaft 53 that is rotatably connected to the cleaning frame 51 and is unidirectionally connected to the push rod 41.

[0034] When the brush plate slide column 522 is located in the straight slide groove 514, the two brush plates 52 can move away from each other; when the brush plate slide column 522 is located in the smooth slide groove 513, the brush plate 52 and the submarine cable are not directly opposite each other in the vertical direction, and the brush plate 52 can rotate and switch.

[0035] The rotating sleeve 525 has a driven abutment 526 formed at one end near the other brush plate 52, and the driven abutment 526 has an inclined driven slope 524 formed at one end near the submarine cable; the outer wall of the drive shaft 53 has a drive push rod 531 formed, which can push the driven slope 524 away from the other brush plate 52; a compression spring 56 is provided between the brush plate 52 and the fixed shaft 511 for pushing the brush plate 52 towards the other brush plate 52.

[0036] The rotating sleeve 525 has a movable ratchet 523 formed at the end away from the submarine cable, and a fixed ratchet 512 is fixedly connected to the outer periphery of the fixed shaft 511, which allows the rotating sleeve 525 to rotate only in one direction; the movable ratchet 523 is made of an elastic material, such as rubber.

[0037] When the brush plate slide column 522 is not aligned with the smooth groove 513, the drive shaft 53 rotates, causing the brush plate slide column 522 to move within the straight groove 514.

[0038] When the brush plate slide column 522 is aligned with the smooth groove 513, the drive shaft 53 rotates, causing the brush plate slide column 522 to slide into the smooth groove 513. The brush plates 52 rotate synchronously. After the brush plate slide column 522 moves into the inclined slide groove 515, the drive push rod 531 separates from the driven abutment plate 526, and the brush plates 52 can move closer to each other.

[0039] The base 1 is rotatably connected to a synchronous rotating shaft 43 for driving the push rod 41 to slide; the push rod 41 is fixedly connected to a driven sleeve 415 that slides relative to the synchronous rotating shaft 43 in the axial direction and rotates synchronously in the circumferential direction; the outer wall of the driven sleeve 415 is formed with a spirally arranged spiral groove 416; the base 1 is slidably connected to a pin 4101 along the radial direction of the driven sleeve 415 that can slide with the spiral groove 416.

[0040] The end of the pin 4101 away from the driven sleeve 415 is fixedly connected to a circulating slide column 4102 arranged perpendicular to the sliding direction. The side wall of the push rod 41 is formed with a reciprocating slide groove that is slidably connected to the circulating slide column 4102. The reciprocating slide groove includes an upward slide groove 414 arranged in the vertical direction, a downward slide groove 417 arranged parallel to the upward slide groove 414 and located on the side of the upward slide groove 414 away from the driven sleeve 415, and two horizontally arranged transition slide grooves 418 located at both ends of the push rod 41 and connecting the upward slide groove 414 and the downward slide groove 417. The two ends of the transition slide groove 418 are respectively connected to one end of the upward slide groove 414 and one end of the downward slide groove 417.

[0041] A pin spring 4103 is provided between the pin 4101 and the seat 1 for pushing the pin 4101 away from the driven sleeve 415.

[0042] When the push rod 41 moves to the lower limit position, the circulating slide column 4102 is located in the upper sliding groove 414, the pin 4101 is slidably connected to the spiral groove 416, the rotation of the synchronous rotating shaft 43 causes the driven sleeve 415 to drive the push rod 41 to move upward, and the pin spring 4103 contracts to store force.

[0043] When the push rod 41 moves to the upper limit position, the pin spring 4103 pushes the circulating slide column 4102 to move through the lower transition slide 418 into the falling slide 417, the pin 4101 separates from the spiral slide 416, and the driven sleeve 415 can move downward under its own gravity.

[0044] A one-way push block 4104 is slidably connected to the push rod 41 above the falling slide groove 417 in the vertical direction. The lower end of the one-way push block 4104 is formed with an inclined push surface 4105 that can push the pin 4101 towards the driven sleeve 415. The end face of the one-way push block 4104 near the driven sleeve 415 is located in the upward slide groove 414. A push block spring 4106 is provided between the one-way push block 4104 and the push rod 41 for pushing the one-way push block 4104 downward.

[0045] During the downward movement of the push rod 41, the circulating slide 4102 abuts against the one-way push block 4104, causing the one-way push block 4104 to move upward relative to the push rod 41, and the push block spring 4106 contracts to store force.

[0046] When the push rod 41 moves to the lower limit position, the circulating slide column 4102 is directly opposite the upper transition slide groove 418. The pushing inclined surface 4105 moves downward under the elastic force of the push block spring 4106. The circulating slide column 4102 moves through the upper transition slide groove 418 into the upper moving slide groove 414. The pin 4101 is slidably connected to the spiral slide groove 416, and the pin spring 4103 contracts to store force.

[0047] A connecting rod 46 is rotatably connected to the base 1, which can drive the two clamping blocks 48 to move closer to each other. A switching block 49 is rotatably connected to the base 1, which can drive the connecting rod 46 to rotate. A lever 492 that can abut against the outer wall of the push rod 41 is fixedly connected to the outer wall of the switching block 49. The outer wall of the push rod 41 is formed with two vertically arranged reset grooves 413. A connecting rod torsion spring 461 is provided between the connecting rod 46 and the base 1 for driving the connecting rod 46 to rotate to the middle position. The inner wall of the reset groove 413 is formed with a guide surface 419 that can squeeze and push the lever 492.

[0048] A sliding plate 47 capable of moving the clamping block 48 is slidably connected to the base 1 in the horizontal direction; a clamping slide post 481 is formed on one end of the clamping block 48 near the opening and closing plate 47, and an opening and closing slide groove 471 inclinedly connected to the clamping slide post 481 is formed on one end of the opening and closing plate 47 near the clamping block 48; a connecting rod slide post 472 slidably connected to one end of the connecting rod 46 is formed on one end of the opening and closing plate 47 near the connecting rod 46; a switching rod 45 is slidably connected to the base 1 in the horizontal direction, and a synchronous slide rod 452 slidably connected to the other end of the connecting rod 46 is formed on one end of the switching rod 45 near the pushing rod 41; a switching slide groove 451 arranged in the vertical direction is formed on the outer wall of the switching rod 45 near the pushing rod 41, and a switching slide post 491 eccentrically connected to the switching slide groove 451 is fixedly connected to the outer wall of the switching block 49.

[0049] When the push rod 41 is at its lower limit position, the lever 492 is located in the upper reset groove 413. The upward movement of the push rod 41 causes the upper guide surface 419 to push the lever 492 to rotate in the positive direction. The connecting rod 46 rotates to the positive limit position so that the two clamping blocks 48 move away from each other and do not contact the submarine cable.

[0050] When the push rod 41 is at the upper limit position, the lever 492 is located in the lower reset groove 413. The downward movement of the push rod 41 causes the lower guide surface 419 to push the lever 492 to rotate in the opposite direction. The connecting rod 46 rotates to the reverse limit position, causing the two clamping blocks 48 to move closer to each other and clamp the submarine cable.

[0051] The recovery assembly 2 also includes a circulation rod 23 rotatably connected to the base 1, and a sliding sleeve 24 slidably connected to the circulation rod 23 for driving the submarine cable to move back and forth. The inner wall of the sliding sleeve 24 is rotatably connected to a slider 25 whose rotating shaft is perpendicular to the rotating shaft of the circulation rod 23.

[0052] The outer wall of the circulating rod 23 is formed with a circulating groove that is slidably connected to the slider 25. The circulating groove includes a first spiral groove 231 with a spiral arrangement, a second spiral groove 232 with a spiral arrangement, and two connecting grooves 233 located at the two ends of the circulating rod 23, connecting the first spiral groove 231 and the second spiral groove 232. The spiral direction of the first spiral groove 231 is opposite to the spiral direction of the second spiral groove 232. The two ends of the connecting groove 233 are respectively connected to the end of the first spiral groove 231 and the end of the second spiral groove 232.

[0053] During the rotation of the circulation rod 23, the slider 25 moves within the first spiral groove 231, causing the sliding sleeve 24 to drive the submarine cable to move in the forward direction. The slider 25 moves within the second spiral groove 232, causing the sliding sleeve 24 to drive the submarine cable to move in the reverse direction. The sliding sleeve 24 reciprocates, causing the submarine cable to be evenly wound around the recovery disc 21.

[0054] The base 1 is rotatably connected to a rotating shaft that is driven by the push rod 41 and is arranged in the vertical direction as a synchronous shaft 651. The synchronous shaft 651 is driven by the cleaning roller 54. A friction wheel 66 is slidably connected to the synchronous shaft 651 in the vertical direction and is fixed relative to the synchronous shaft 651 in the circumferential direction. The friction wheel 66 is in close contact with the recycling disc 21.

[0055] A synchronization frame 61 is slidably connected to the base 1 along the radial direction of the recovery tray 21. A clamping roller 611 is rotatably connected to the synchronization frame 61 to abut against the submarine cable wound on the recovery tray 21. A synchronization spring 612 is provided between the synchronization frame 61 and the base 1 to push the synchronization frame 61 toward the axis of rotation of the recovery tray 21. An adjustment frame 64 is slidably connected to the base 1 to drive the friction wheel 66 to move. The adjustment frame 64 is kinetically connected to the synchronization frame 61.

[0056] A lifting gear 431 is fixedly connected to the lower end of the synchronous rotating shaft 43, and a transmission gear 44, which is rotatably connected to the lifting gear 431, is rotatably connected to the base 1; a fixed gear 652 is fixedly connected to the lower end of the synchronous shaft 651, and an output gear 653, which is rotatably connected to the fixed gear 652, is rotatably connected to the base 1; a driving synchronous belt is provided between the synchronous bevel gear 55, the transmission gear 44, and the output gear 653.

[0057] A synchronous bevel gear 55, which is driven by the synchronous shaft 651, is rotatably connected to the base 1; a driven bevel gear 541, which is driven by the synchronous bevel gear 55, is fixedly connected to one end of the cleaning roller 54; an adjusting rack 641, which is arranged in the vertical direction, is formed on the adjusting frame 64; an adjusting gear 63, which is driven by the adjusting rack 641, is rotatably connected to the base 1; a synchronous gear 62 is rotatably connected to the base 1; a synchronous rack 613, which is driven by the synchronous gear 62, is formed on the synchronous frame 61; and an adjusting synchronous belt is provided between the adjusting gear 63 and the synchronous gear 62.

[0058] As the recovery tray 21 rotates, the thickness of the submarine cable on the recovery tray 21 increases. The synchronization frame 61 drives the friction wheel 66 to move away from the axis of rotation of the recovery tray 21. The length of the submarine cable recovered after one rotation of the recovery tray 21 increases, the number of rotations of the friction wheel 66 increases, and the switching frequency of the brush plate 52 increases to ensure that the brush plate 52 is cleaned after cleaning submarine cables of the same length.

[0059] A one-way drive wheel 421, which is driven by the drive shaft 53, is rotatably connected to the base 1. A one-way transmission gear 422, which is driven by the push rod 41, is rotatably connected to the base 1. The one-way transmission gear 422 is unidirectionally connected to the one-way drive wheel 421.

[0060] A driving end face ratchet 423 is fixedly connected to one end of the one-way drive wheel 421 near the one-way transmission gear 422; a driven end face ratchet 424 is fixedly connected to one end of the one-way transmission gear 422 near the one-way drive wheel 421; the driving end face ratchet 423 and the driven end face ratchet 424 are connected in a one-way transmission; both the driving end face ratchet 423 and the driven end face ratchet 424 are made of elastic material, such as rubber; the outer wall of the push rod 41 is formed with a push rack 412 that is arranged in the up-down direction and is connected in transmission to the one-way transmission gear 422.

[0061] The recovery tray 21 includes a drive tray 212 rotatably connected to the base 1, a movable tray 211 for storing submarine cables detachably connected to the drive tray 212 and capable of rotating synchronously with the drive tray 212, and a latch 27 detachably connected to the drive tray 212 to prevent the movable tray 211 from disengaging; a synchronization block 213 fixedly connected to the drive tray 212 and relatively fixed to the movable tray 211 in the circumferential direction.

[0062] A controller is fixedly connected inside the base 1, and a switch is provided on the base 1; the camera, the switch, the motor 26 are electrically connected to the controller.

[0063] In the initial state, the push rod 41 is in the lower limit position, the clean end of the brush plate 52 covers the submarine cable, the dirty end covers the cleaning roller 54, the two clamping blocks 48 do not clamp the submarine cable, and the push rod 41 is in the lower limit position.

[0064] Before recovering submarine cables, it is necessary to inspect their appearance. During use, submarine cables often have various impurities attached to their surface. These impurities need to be removed before inspection to avoid affecting the inspection results.

[0065] When using this invention, pressing the switch activates the controller, which in turn controls the motor 26 to operate. The operation of the motor 26 rotates the recovery tray 21, causing the submarine cable to move. The submarine cable passes through the cleaning component 5 and the detection component 3 in sequence, and finally wraps around the recovery tray 21 to complete the recovery. When the submarine cable passes through the cleaning component 5, the surface of the submarine cable rubs against the bristles 521 on the brush plate 52. The bristles 521 brush away the impurities attached to the submarine cable, and the washed-off impurities adhere to the bristles 521 to form dirt. When the submarine cable, after the impurities have been brushed away, passes through the detection component 3, the detection component 3 checks the degree of damage to the submarine cable's outer sheath. If the outer sheath is undamaged, the submarine cable is wrapped around the recovery tray 21 for recovery. If the outer sheath is damaged, the controller stops the motor 26, allowing for repair of the damaged area.

[0066] During this process, the operation of motor 26 drives the circulation rod 23 to rotate, and the rotation of circulation rod 23 drives slider 25 to move in circulation groove. Sliding slider 25 moves in first spiral groove 231, causing sliding sleeve 24 to drive submarine cable to move forward. Sliding slider 25 moves in second spiral groove 232, causing sliding sleeve 24 to drive submarine cable to move in the opposite direction. As circulation rod 23 continues to rotate, sliding sleeve 24 drives submarine cable to move back and forth, so that submarine cable is evenly wound on recovery disc 21.

[0067] At the same time, the rotation of the recycling disc 21 drives the friction wheel 66 to rotate through friction. The rotation of the friction wheel 66 drives the synchronous shaft 651 to rotate, causing the fixed gear 652 to rotate. The rotation of the fixed gear 652 drives the output gear 653 to rotate, causing the drive synchronous belt to operate. The operation of the drive synchronous belt drives the transmission gear 44 and the synchronous bevel gear 55 to rotate.

[0068] The rotation of the synchronous bevel gear 55 drives the driven bevel gear 541 to rotate, causing the cleaning roller 54 to rotate. During the rotation of the cleaning roller 54, the cleaning ridges on the cleaning roller 54 rub and clean the bristles 521 covering the cleaning roller 54, and the dirt attached to the bristles 521 is removed.

[0069] The rotation of the transmission gear 44 drives the lifting gear 431 to rotate, causing the synchronous shaft 43 to rotate. The rotation of the synchronous shaft 43 drives the driven sleeve 415 to rotate synchronously. Since the pin 4101 is slidably connected to the spiral groove 416 at this time, the driven sleeve 415 moves upward during the rotation. The circulating slide column 4102 moves in the upward sliding groove 414. The movement of the driven sleeve 415 drives the push rod 41 to move. The movement of the push rod 41 drives the push wheel 411 to move upward, causing a part of the cleaned submarine cable to protrude upward.

[0070] In addition, the upward movement of the push rod 41 causes the push rack 412 to move upward, which causes the one-way transmission gear 422 to rotate in the forward direction. The rotation of the one-way transmission gear 422 causes the drive end ratchet 423 to rotate. At this time, the rotation of the drive end ratchet 423 does not drive the driven end ratchet 424 to rotate, and the one-way transmission gear 422 does not rotate.

[0071] The upward movement of the push rod 41 also causes the guide surface 419 in the upper reset groove 413 to press and push the lever 492, causing the switching block 49 to rotate in the forward direction. The forward rotation of the switching block 49 drives the switching slide column 491 to move. The movement of the switching slide column 491 drives the switching slide groove 451 to move, causing the switching rod 45 to move. The movement of the switching rod 45 drives the synchronous slide rod 452 to move, causing the connecting rod 46 to rotate in the forward direction. The connecting rod torsion spring 461 twists and stores power. The rotation of the connecting rod 46 drives the connecting rod slide column 472 to move, causing the opening and closing plate 47 to move in the forward direction. The movement of the opening and closing plate 47 drives the two opening and closing slide grooves 471 to move. The movement of the opening and closing slide grooves 471 drives the clamping slide column 481 to move, causing the two clamping blocks 48 to move away from each other.

[0072] When the push rod 41 moves to the upper limit position, the lever 492 on the switching block 49 is aligned with the lower reset groove 413, and the lever 492 no longer abuts against the outer wall of the push rod 41. At this time, the connecting rod 46 rotates to the middle position under the elastic force of the connecting rod torsion spring 461, and the lever 492 moves into the lower reset groove 413. At the same time, the circulating slide 4102 on the pin 4101 moves to the lower end of the upward slide groove 414 and is aligned with the lower transition slide groove 418.

[0073] Next, the pin 4101 moves out of the spiral groove 416 under the elastic force of the pin spring 4103, and the circulating slide 4102 moves into the falling groove 417. At this time, the push rod 41 begins to slide down a distance under its own gravity.

[0074] The downward movement of the push rod 41 causes the guide surface 419 in the lower reset groove 413 to press the lever 492, causing the switching block 49 to rotate in the opposite direction. The reverse rotation of the switching block 49 causes the two clamping blocks 48 to move closer to each other and clamp the submarine cable, so that the submarine cable located on the side of the clamping block 48 near the cleaning component 5 no longer moves. At this time, the rotation of the recovery disc 21 causes a portion of the submarine cable that protrudes upward to be recovered. The recovered submarine cable recovers from a bend to a straight line. During the recovery process, the push rod 41 slides further downward.

[0075] The downward movement of push rod 41, on the other hand, drives push rack 412 to move downward. The movement of push rack 412 drives one-way transmission gear 422 to rotate, causing drive end face ratchet 423 to rotate in the opposite direction. The rotation of drive end face ratchet 423 drives driven end face ratchet 424 to rotate, causing one-way drive wheel 421 to rotate in the opposite direction. The rotation of one-way drive wheel 421 drives drive shaft 53 to rotate, and the rotation of drive shaft 53 drives each drive push rod 531 to rotate.

[0076] The drive push rod 531 rotates and abuts against the driven inclined surface 524. The drive push rod 531 continues to rotate, causing the driven inclined surface 524 to be pushed away from the other brush plate 52. The compression spring 56 contracts and stores force. The movement of the driven inclined surface 524 causes the rotating sleeve 525 to move, causing the brush plate 52 to move. The brush plate slide column 522 in the rotating sleeve 525 moves away from the end of the submarine cable in the straight slide groove 514. At this time, because the drive push rod 531 squeezes the driven inclined surface 524, the rotating sleeve 525 has a circumferential rotation component force. Therefore, when the brush plate slide column 522 is directly opposite the smooth groove 513, the brush plate slide column 522 moves from the straight slide groove 514 to the smooth groove 513. The rotating sleeve 525 rotates circumferentially. At this time, the brush plate slide column 522 cannot continue to move away from the other brush plate 52. The rotation of the drive push rod 531 causes the rotating sleeve 525 to continue to rotate circumferentially.

[0077] Next, the brush plate slide column 522 moves to the connection between the smooth groove 513 and the inclined groove 515. The continued rotation of the drive push rod 531 causes the brush plate slide column 522 to move into the inclined groove 515, and the brush plate 52 continues to move away from the submarine cable. When the brush plate slide column 522 moves to the connection between the inclined groove 515 and the straight groove 514, the drive push rod 531 separates from the driven inclined surface 524. The continued movement of the drive push rod 531 passes over the driven abutment plate 526. Then, under the elastic force of the compression spring 56, the brush plates 52 move closer to each other, so that the end of the brush plate 52 with dirt on it covers the cleaning roller 54, and the cleaned end covers the submarine cable, completing the switching of the brush plate 52.

[0078] As the push rod 41 moves downward, the circulating slide 4102 abuts against the one-way push block 4104 and pushes the one-way push block 4104 upward, causing the push block spring 4106 to contract and store force. When the push rod 41 moves to its lower limit position, the circulating slide 4102 is aligned with the upper transition groove 418, and the one-way push block 4104 moves downward under the elastic force of the push block spring 4106, pushing the inclined plane 4105 to compress and push the circulating slide 4102. The pin 4101 moves toward the driven sleeve 415; when the one-way push block 4104 moves to the lower limit position, the circulating slide 4102 moves into the upper sliding groove 414, and the pin 4101 is slidably connected to the spiral groove 416. At this time, the side wall of the one-way push block 4104 near the driven sleeve 415 is located in the upper sliding groove 414, so that the circulating slide 4102 cannot move to the lower sliding groove 417 through the upper transition groove 418.

[0079] Then, the recycling tray 21 continues to recycle the submarine cable. The submarine cable is washed, tested and then recycled, and this process is repeated.

[0080] During the process of winding and recovering submarine cables, since the rotational angular velocity of the recovery disc 21 remains constant, as the thickness of the recovered submarine cable increases, the length of the submarine cable recovered in one rotation of the recovery disc 21 increases, and the length of the brush bristles 521 brushing in a single stroke increases. This may lead to a decrease in the brushing effect due to excessive dirt adhesion. Therefore, it is necessary to adjust the switching frequency of the brush plate 52 in a timely manner according to the needs.

[0081] The clamping roller 611 on the synchronizing frame 61 presses against the surface of the recovered submarine cable. As the thickness of the wound submarine cable increases, the synchronizing frame 61 moves away from the axis of rotation of the recovery disc 21. The synchronizing spring 612 contracts and stores force. The movement of the synchronizing frame 61 drives the synchronizing rack 613 to move, causing the synchronizing gear 62 to rotate. The rotation of the synchronizing gear 62 drives the adjusting synchronizing belt to operate, causing the adjusting gear 63 to rotate. The rotation of the adjusting gear 63 drives the adjusting rack 641 to move, causing the adjusting frame 64 to move away from the axis of rotation of the recovery disc 21. The movement of the adjusting frame 64 drives the friction wheel 66 to move synchronously. As the distance between the friction wheel 66 and the axis of rotation of the recovery disc 21 increases, the number of rotations of the friction wheel 66 driven by one rotation of the recovery disc 21 increases synchronously, which increases the frequency of movement of the push rod 41, and thus increases the frequency of switching of the brush plate 52, so as to ensure that the length of submarine cable cleaned is equal each time the brush plate 52 is switched.
