Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a watertight cable and its processing equipment. Background Technology

[0002] Watertight cables are special cables designed specifically for underwater or extremely humid environments. Their main function is to ensure reliable power transmission and signal transmission in high-pressure underwater environments, while preventing water from seeping into the cable structure and ensuring the safety of connected equipment.

[0003] Existing watertight cables generally require regular inspection and maintenance during use in underwater environments. However, it is currently difficult to quickly determine the location of the cable in underwater environments. In order to facilitate the rapid location and inspection and maintenance of cables in turbid or deep water, a technical solution of wrapping self-luminous tape around the outer layer of watertight cables has emerged in recent years.

[0004] Currently, the processing technology for wrapping self-illuminating tape to the cable body mainly relies on wrapping equipment. This involves continuously wrapping the self-illuminating tape along the length of the cable body until it completely covers the outer layer. However, after wrapping this type of tape, existing wrapping equipment generally requires manual intervention to stop and cut the tape promptly, which is obviously inefficient. Although some wrapping equipment can automatically cut, the cutting blades are usually positioned in a fixed location, meaning they can only cut from one side. This requires the equipment to stop precisely on the corresponding side each time it wraps the tape, and then the cutting blade on that side will cut. Alternatively, multiple sets of blades can be used, with the blade on the corresponding side triggered based on the final stopping position of the self-illuminating tape. However, these cutting methods are not very effective and are cumbersome and inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a watertight cable and its processing equipment to solve the technical problems of insufficient cutting effect and inconvenient operation when cutting watertight cables after the surface wrapping material is completed in the prior art.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution: A watertight cable includes a cable body and a self-illuminating strip wrapped around the outer layer of the cable body.

[0007] A watertight cable processing device includes a rotary wrapping mechanism and a traction and winding mechanism for pulling and winding the watertight cable. The rotary wrapping mechanism is used to wrap self-illuminating tape onto the cable body, and also includes an automatic cutting mechanism. The automatic cutting mechanism includes a ring cutter, a cable detection mechanism, and a transverse drive mechanism. The ring cutter is coaxially fitted with the cable body and is located on one side of the rotating wrapping mechanism. When the cable detection mechanism detects that the self-illuminating tape wrapped around the cable body has reached a set length, it drives the ring cutter to automatically move transversely and cut the self-illuminating tape between the cable body and the rotating wrapping mechanism through the transverse drive mechanism.

[0008] Preferably, the rotating wrapping mechanism includes an annular support, a rotating drum, a light-emitting tape reel, and a drive source for driving the rotating drum to rotate; the rotating drum is rotatably connected to the annular support; the cable body is distributed along the axis of the rotating drum, and the annular cutter is coaxially aligned with the rotating drum; the light-emitting tape reel is rotatably connected to the edge of the rotating drum near the annular cutter; the self-luminous tape is wound onto the light-emitting tape reel, and the starting end of the self-luminous tape is adhered to the cable body.

[0009] Preferably, the drive source includes a linkage gear ring and a drive gear. The linkage gear ring is coaxially and fixedly connected to the outer ring of the rotating cylinder. The drive gear meshes with one side of the linkage gear ring, and the drive gear drives the rotating cylinder to rotate through the linkage gear ring.

[0010] Preferably, the rotating wrapping mechanism further includes an auxiliary clamping mechanism for automatically clamping and fixing the self-illuminating tape when the annular cutter cuts the self-illuminating tape.

[0011] Preferably, the auxiliary clamping mechanism includes a mounting frame and clamping blocks. The mounting frame is fixedly connected to the rotating cylinder, and a guide rod is fixedly connected to the inner side of the mounting frame. Two clamping blocks are provided and distributed inside the mounting frame, and the guide rod passes through the two clamping blocks. A limit spring is connected between each clamping block and the corresponding side of the mounting frame, and the self-illuminating strip passes between the two clamping blocks. A linkage opening and closing mechanism is also provided between the two clamping blocks.

[0012] Preferably, the linkage opening and closing mechanism includes a first linkage plate and a pressing block. Two first linkage plates are provided, and each is movably connected to a clamping block via a hinge. The pressing block is movably connected between the two first linkage plates via a hinge. The automatic cutting mechanism also includes a linkage ring fixedly connected to an annular cutter. The edge of the linkage ring is aligned and engaged with the pressing block.

[0013] Preferably, the cable inspection mechanism includes an elastic lifting bracket, a fixed frame, and a fixed guide rail; the fixed frame is located on the side of the annular cutter away from the rotating wrapping mechanism, and the elastic lifting bracket is vertically slidably connected to the fixed frame; a support spring is also connected between the elastic lifting bracket and the fixed frame; a slide is fixedly connected to the bottom of the annular cutter and slidably connected to the fixed guide rail, and a storage spring is connected between the slide and the fixed guide rail; a second linkage plate is movably connected to the bottom of the elastic lifting bracket via a hinge, and the end of the second linkage plate away from the elastic lifting bracket is movably connected to the slide via a hinge.

[0014] Preferably, the processing equipment further includes a central clamping support mechanism, wherein two sets of the central clamping support mechanism are provided, one set of the central clamping support mechanism being located on the side of the annular cutter away from the rotating wrapping mechanism, and the other set of the central clamping support mechanism being located on the side of the rotating wrapping mechanism away from the annular cutter; the two sets of the central clamping support mechanism are used to position and support the main cable body at the central axis position of the annular cutter.

[0015] Preferably, each set of centrally clamping support mechanisms includes a positioning ring, an electric push rod, and a clamping wheel; the central axis of the positioning ring coincides with the central axis of the annular cutter; multiple electric push rods are provided and are circumferentially and equidistantly fixedly connected to the positioning ring, and the telescopic end of each electric push rod is radially aligned with the center of the positioning ring; the telescopic end of each electric push rod is rotatably connected to a clamping wheel.

[0016] The beneficial effects of this invention are: 1. The present invention uses a rotating wrapping mechanism to wrap the self-luminous tape to the surface of the cable body, and relies on a set annular cutter to cut the tail of the wrapped self-luminous tape. It does not require the tail of the self-luminous tape to stop at a specific position. After the cable body is wrapped, the annular cutter is automatically triggered to run, so as to achieve automatic cutting of the self-luminous tape in any direction.

[0017] 2. During the transverse winding of the self-illuminating tape, once the end of the cable body is separated from the set elastic lifting bracket, the elastic lifting bracket will rise under the action of spring rebound force. At the same time, the annular cutter will release synchronously by relying on the spring rebound force to complete the cutting action, realizing mechanical linkage triggering, making the operation more reliable and the response more direct. No additional control system is required, avoiding the problems of response delay and susceptibility to interference.

[0018] 3. When the annular cutter of the present invention moves to cut the self-illuminating strip by relying on the released elastic force, the annular cutter drives the set linkage ring to move synchronously. The linkage ring then disengages from the squeezing block of the set auxiliary clamping mechanism. The two clamping blocks that are opened by the squeezing block and the first linkage plate are unlocked, and thus rely on the corresponding spring rebound force to clamp and fix the self-illuminating strip, so that the annular cutter can effectively cut it and avoid the self-illuminating strip being soft and bending, which would affect the cutting effect.

[0019] 4. The watertight cable of the present invention has a self-luminous tape wrapped around its surface. The self-luminous tape emits light in the underwater environment, which facilitates quick location of the cable during subsequent inspection and maintenance, thereby improving the efficiency of inspection and maintenance.

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] like Figure 1 As shown, a watertight cable is used in underwater environments, such as for laying on the seabed. The cable includes a cable body 1, which, from the inside out, includes a conductor, a conductor water-blocking layer, an insulation layer, a shielding layer, a water-blocking isolation layer, and an outer sheath, providing water-blocking functionality and effective protection in humid environments. The cable also includes a self-luminous strip 2, which is wrapped around the outer layer of the cable body 1. The self-luminous strip 2 can be made of fluorescent material with emission spectrum peaks in the blue-green band, which facilitates effective luminescence in turbid or deep water, thus facilitating quick location of the cable body 1 during inspection and maintenance.

[0024] like Figures 2 to 11As shown, for the aforementioned watertight cable, this solution also provides a watertight cable processing device for winding and fixing the self-illuminating tape 2 onto the surface of the cable body 1. This processing device includes a rotating winding mechanism 5 and a traction winding mechanism 3 for pulling and winding the watertight cable. The rotating winding mechanism 5 is used to wind the self-illuminating tape 2 onto the cable body 1. It should be noted that the self-illuminating tape 2 is initially wound together, with the inward-facing side being a pressure-sensitive adhesive layer, facilitating the initial adhesion of the self-illuminating tape 2 to the surface of the cable body 1. The traction winding mechanism 3 is an existing mechanism and may include a winding reel and a servo motor that drives the winding reel to rotate at a certain speed, winding the tape... During the process of wrapping the self-luminous tape 2, the cable body 1 moves laterally to facilitate the overall wrapping of the self-luminous tape 2. The processing equipment also includes an automatic cutting mechanism 8, which includes an annular cutter 82, a cable detection mechanism, and a lateral movement drive mechanism. The annular cutter 82 is coaxially arranged with the cable body 1 and is located on one side of the rotating wrapping mechanism 5. When the cable detection mechanism detects that the cable body 1 has wrapped the self-luminous tape 2 to a set length, it drives the annular cutter 82 to automatically move laterally and cut the self-luminous tape 2 between the cable body 1 and the rotating wrapping mechanism 5 through the lateral movement drive mechanism, thereby achieving automatic cutting without the need for manual shutdown and improving the convenience of operation.

[0025] In some specific implementation schemes, refer to Figure 4 and Figure 5 As shown, the rotating wrapping mechanism 5 includes an annular support 51, a rotating drum 52, a light-emitting strip reel 53, and a drive source for driving the rotating drum 52 to rotate. The annular support 51 is fixedly mounted on the base 4 of the entire processing equipment. The rotating drum 52 is rotatably connected to the annular support 51. Specifically, an annular groove can be formed in the inner ring of the annular support 51. The rotating drum 52 is slidably connected to the annular groove through pulleys, and the rotating drum 52 is limited to the annular support 51 and cannot be detached. The cable body 1 is distributed along the axis of the rotating drum 52, and the annular cutter 82 is coaxially aligned with the rotating drum 52. That is, the cable body 1 passes through the annular cutter 82 and the rotating drum 52 in sequence. The light-emitting tape reel 53 is rotatably connected to the edge of the rotating drum 52 near the annular cutter 82, and the rotation axis of the light-emitting tape reel 53 is parallel to the axis of the rotating drum 52. The self-luminous tape 2 is wound on the light-emitting tape reel 53, and the starting end of the self-luminous tape 2 is bonded to the cable body 1.

[0026] In a further embodiment, the driving source may include a linkage gear ring 55 and a drive gear 56. The linkage gear ring 55 is coaxially fixedly connected to the outer ring of the rotating drum 52, and the drive gear 56 meshes with one side of the linkage gear ring 55. The drive gear 56 is driven to rotate by a motor, thereby driving the rotating drum 52 to rotate at a set speed through the linkage gear ring 55. With the starting end of the self-luminous tape 2 adhered to the cable body 1, as the rotating drum 52 continues to rotate, the self-luminous tape 2 winds and adheres to the cable body 1. Simultaneously, as the cable body 1 moves laterally, the self-luminous tape 2 continues to wind along the length of the cable body 1. During this process, the self-luminous tape 2 is continuously released from the rotatable luminous tape reel 53. It should also be noted that, to prevent the luminous tape reel 53 from rotating excessively during the rotation of the rotating drum 52, causing the self-luminous tape 2 to become overly loose, a certain amount of frictional resistance can be present at the point where the luminous tape reel 53 is rotatably connected to the rotating drum 52. For example, a fixed shaft can be vertically fixed to the side wall of the rotating drum 52, and the outer wall of the fixed shaft or the inner wall of the luminous tape reel 53 can be used to create frictional resistance. A rubber anti-slip sleeve is fixedly connected, and the light-emitting tape roll 53 is rotatably sleeved outside the fixed shaft. That is, the two are in contact by the rubber anti-slip sleeve. At the same time, a stop block is threadedly connected to the end of the fixed shaft to prevent the light-emitting tape roll 53 from falling off. This can prevent the light-emitting tape roll 53 from rotating at will, and it can only rotate under a certain tension. This keeps the self-emitting tape 2 between the light-emitting tape roll 53 and the cable body 1 taut. Of course, a device for applying pressure to the light-emitting tape roll 53 can also be directly fixedly installed on the rotating drum 52. For example, an electric telescopic rod can be vertically fixedly installed, with a rubber anti-slip pad installed at the telescopic end of the electric telescopic rod. The electric telescopic rod drives the rubber anti-slip pad to abut against one end face of the light-emitting tape roll 53 by a certain pressure.

[0027] In a further specific implementation, to prevent the self-luminous tape 2 from bending and deforming due to its flexibility when the annular cutter 82 laterally cuts the self-luminous tape 2 between the luminous tape reel 53 and the cable body 1, thus failing to cut it effectively, refer to... Figure 4 , Figure 5 as well as Figures 8 to 10 As shown, the rotating wrapping mechanism 5 also includes an auxiliary clamping mechanism 54. The auxiliary clamping mechanism 54 is used to automatically clamp and fix the self-luminous tape 2 near the position of the light-emitting tape 2 when the annular cutter 82 moves laterally close to the position of the self-luminous tape 2 for cutting, so as to facilitate the annular cutter 82 to cut it. It should be noted that the entire auxiliary clamping mechanism 54 is outside the range of motion of the annular cutter 82 to avoid hindering the lateral movement of the annular cutter 82.

[0028] In some specific designs, the auxiliary clamping mechanism 54 includes a mounting frame 541 and clamping blocks 543. The mounting frame 541 is fixedly connected to the rotating cylinder 52 via a bracket. A guide rod 546 is fixedly connected to the inner side of the mounting frame 541, and there are two guide rods 546 in pairs. Two clamping blocks 543 are provided and distributed inside the mounting frame 541, with the guide rod 546 passing through both clamping blocks 543. Both clamping blocks 543 can slide along the guide rod 546. Each clamping block 543... A compressible limiting spring 542 is connected to each side corresponding to the mounting frame 541. The two limiting springs 542 are symmetrically located. When the limiting springs 542 are in their original state, the two clamping blocks 543 are in contact with each other, and the self-illuminating strip 2 passes between the two clamping blocks 543. In order to facilitate the two clamping blocks 543 to firmly clamp the self-illuminating strip 2, interlocking teeth are distributed on the opposite surfaces of the two clamping blocks 543. A linkage opening and closing mechanism is also provided between the two clamping blocks 543. In addition, it should be noted that the edge of the annular cutter 82 is close to the side of the clamping block 543 near the cable body 1, so that it is convenient to cut effectively from the clamping position as close as possible to the clamping block 543 during subsequent cutting.

[0029] Furthermore, the linkage opening and closing mechanism includes a first linkage plate 544 and a pressing block 545. Two first linkage plates 544 are provided, and are respectively movably connected to the clamping block 543 by hinges, and are distributed on the same side of the two clamping blocks 543. The pressing block 545 is movably connected between the two first linkage plates 544 by hinges. When the two first linkage plates 544 are in the initial position, they combine to form a V-shaped body. The automatic cutting mechanism 8 also includes a linkage ring 85 fixedly connected to the annular cutter 82 by a bracket. In order to avoid the linkage ring 85 from hindering the auxiliary clamping mechanism 54 and the self-illuminating strip 2 from rotating around the cable body 1, the linkage ring 85 can be placed on the side of the auxiliary clamping mechanism 54 away from the annular cutter 82, and the bracket connecting the annular cutter 82 and the linkage ring 85 passes around the outer ring of the rotating cylinder 52. The edge of the linkage ring 85 is aligned and engaged with the pressing block 545.

[0030] When the annular cutter 82 is in a position away from the auxiliary clamping mechanism 54, the linkage ring 85 abuts against the extrusion block 545. At this time, the extrusion block 545 opens the corresponding clamping block 543 through the two first linkage plates 544, keeping them separated, so that the self-luminous strip 2 can freely pass through the two clamping blocks 543. At the same time, the limiting spring 542 is in a compressed state. When the annular cutter 82 moves laterally closer to the position of the self-luminous strip 2 to cut it, the linkage ring 85 moves synchronously to disengage from the clamping block 543. In this way, the two clamping blocks 543 clamp each other in the middle under the action of the rebound force of the corresponding limiting spring 542, thereby fixing the position of the self-luminous strip 2 close to the luminous strip roll 53, so that the annular cutter 82 can effectively cut it.

[0031] In some specific implementation plans, combined with Figure 4 and Figure 7 As shown, the cable inspection mechanism includes an elastic lifting bracket 81, a fixed frame 84, and a fixed guide rail 83; both the fixed frame 84 and the fixed guide rail 83 are fixedly mounted on the base 4 of the processing equipment; the fixed frame 84 is located on the side of the annular cutter 82 away from the rotating wrapping mechanism 5, and the elastic lifting bracket 81 is vertically slidably connected to the fixed frame 84, specifically, the bottom of the elastic lifting bracket 81 can be a vertical rod that runs longitudinally through the fixed frame 84; the top of the elastic lifting bracket 81 can be a curved panel structure that matches the surface of the cable body 1; a support spring is also connected between the elastic lifting bracket 81 and the fixed frame 84; the bottom of the annular cutter 82... A slide is fixedly connected to a fixed guide rail 83, and a storage spring 86 is connected between the slide and the fixed guide rail 83. The bottom of the elastic lifting bracket 81 is movably connected to a second linkage plate 87 via a hinge. The end of the second linkage plate 87 away from the elastic lifting bracket 81 is movably connected to the slide via a hinge, and the second linkage plate 87 is inclined as a whole. The slide can be in an L-shaped structure. The vertical end is directly fixedly connected to the annular cutter 82, and the horizontal end is connected to the second linkage plate 87. It should also be noted that the initial position of the top of the elastic lifting bracket 81 is higher than the height of the central axis of the annular cutter 82.

[0032] When the cable body 1 is placed on the central axis of the annular cutter 82 and the rotating drum 52, the cable body 1 rests on the elastic lifting bracket 81 and is pressed down by gravity, causing the support spring to stretch and generate a rebound force. During this process, the descending elastic lifting bracket 81 pushes the slide along the fixed guide rail 83 away from the rotating winding mechanism 5 via the inclined second linkage plate 87. The slide then drives the annular cutter 82 to move laterally away from the position of the self-illuminating tape 2, compressing the storage spring 86 to generate a rebound force. The annular cutter 82 also drives the linkage ring 85 to move synchronously. During the lateral movement of the cable body 1 and its winding with the self-illuminating tape 2, once the cable... When the end of the main body 1 detaches from the elastic lifting bracket 81, the elastic lifting bracket 81 instantly springs up due to the rebound force of the support spring. At the same time, the annular cutter 82 also moves laterally to impact the position of the self-illuminating tape 2 due to the rebound force released by the storage spring 86, and performs automatic cutting. This realizes the function of automatically cutting off the self-illuminating tape 2 after detecting that the cable main body 1 has finished wrapping the self-illuminating tape 2. It should be noted that when the cable main body 1 finishes wrapping the self-illuminating tape 2, its end itself will be a certain distance from the position where the wrapping ends. That is, there must be a part of the cable main body 1 near the end that has not been wrapped with the self-illuminating tape 2, and this part is just used to install cable connectors and other devices.

[0033] In some specific implementation schemes, in order to effectively ensure that the cable body 1 can be positioned at the central axis of the annular cutter 82 and the rotating drum 52, so as to facilitate the wrapping of the self-illuminating tape 2 and subsequent cutting work; combined with Figure 4 and Figure 6 As shown, the processing equipment also includes a central clamping support mechanism 6. There are two sets of central clamping support mechanisms 6. One set of central clamping support mechanisms 6 is located on the side of the annular cutter 82 away from the rotating wrapping mechanism 5, specifically between the fixed frame 84 and the annular cutter 82. The other set of central clamping support mechanisms 6 is located on the side of the rotating wrapping mechanism 5 away from the annular cutter 82. The two sets of central clamping support mechanisms 6 are used to position and support the main cable body 1 at the central axis position of the annular cutter 82.

[0034] Each set of centrally located clamping support mechanisms 6 includes a positioning ring 61, an electric push rod 62, and a clamping wheel 63. The central axis of the positioning ring 61 coincides with the central axis of the annular cutter 82, and the positioning ring 61 is fixedly installed relative to the base 4 of the processing equipment. Multiple electric push rods 62 are provided and are circumferentially and equidistantly fixedly connected to the positioning ring 61. The telescopic end of each electric push rod 62 is radially aligned with the center of the positioning ring 61. The telescopic end of each electric push rod 62 is rotatably connected to a clamping wheel 63. All electric push rods 62 are push rods of the same specification and are synchronously telescopically controlled by the same switch.

[0035] The cable body 1 is passed through the positioning rings 61 of the two sets of centrally clamping support mechanisms 6. Then, the electric push rods 62 distributed circumferentially in each set of centrally clamping support mechanisms 6 are controlled to extend synchronously. In this way, the electric push rods 62 push the cable body 1 with the clamping wheels 63, thereby centrally clamping and supporting the cable body 1. Since the clamping wheels 63 can rotate, it can also avoid hindering the lateral movement of the cable body 1. The position of the centrally clamping support mechanism 6 between the fixed frame 84 and the annular cutter 82 is close to the elastic lifting bracket 81, which facilitates the positioning of the cable body 1 at this position. This prevents the cable body 1 from bending upward under the rebound force of the elastic lifting bracket 81 pushing upward. In particular, when the end of the cable body 1 moves close to the position of the centrally clamping support mechanism 6 at this position, but has not yet detached from the elastic lifting bracket 81, the remaining part of the cable body 1 on the side of the centrally clamping support mechanism 6 is shorter and has stronger bending resistance.

[0036] In some specific embodiments, to ensure that the self-luminous tape 2 can be effectively and firmly adhered to the cable body 1, the processing equipment also includes a heating mechanism 7. The heating mechanism 7 includes a hot air blower 71, an annular tube 72, and hot air nozzles 73. The annular tube 72 is located on the side of the rotating wrapping mechanism 5 away from the annular cutter 82, and is located between the rotating wrapping mechanism 5 and another set of centrally clamping support mechanisms 6. The annular tube 72 is fixedly set relative to the base 4 of the processing equipment. The hot air blower 71 is used to deliver hot air into the annular tube 72. Multiple hot air nozzles 73 are provided and are fixedly arranged circumferentially at equal intervals in the inner ring of the annular tube 72. Each hot air nozzle 73 is connected to the annular tube 72, and the cable body 1 passes through the center of the annular tube 72. A thermosetting adhesive layer is also provided between the body of the self-luminous tape 2 and the pressure-sensitive adhesive layer. The thermosetting adhesive layer is a type of adhesive that melts from a solid to a liquid state after heating, wets the surface of the materials to be bonded, and then undergoes a cross-linking reaction to form strong chemical bonds. After cooling, it becomes a tough, durable, and non-melting adhesive layer. The hot air generated by the hot air blower 71 is delivered to the circumferentially distributed hot air nozzles 73 through the annular pipe 72. The hot air nozzles 73 blow the high-pressure, high-temperature air circumferentially onto the cable body 1. The heat-curing adhesive layer of the self-luminous strip 2, heated by the hot air nozzles 73, becomes sticky. Then, the clamping rollers 63 of the corresponding central clamping support mechanism 6 roll the adhesive to ensure the bonding effect, thus facilitating long-term use in underwater environments.

[0037] In some specific implementations, the processing equipment also includes an auxiliary conveying guide roller group 9. Two auxiliary conveying guide roller groups 9 can be set up and distributed on both sides of the base 4. Each auxiliary conveying guide roller group 9 includes two adjustable-spacing rotating rollers, and the rotating rollers are driven by a motor to rotate, so that the cable body 1 passes through the auxiliary conveying guide roller group 9 and is clamped and rotated by the two rotating rollers for auxiliary conveying.

[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: First, the cable body 1 is passed through the positioning rings 61 of the two sets of centrally clamping support mechanisms 6. Then, the electric push rods 62 distributed circumferentially in each set of centrally clamping support mechanisms 6 are controlled to extend synchronously. In this way, the electric push rods 62 push the cable body 1 with the clamping wheel 63, thereby centrally clamping and supporting the cable body 1. In this way, the cable body 1 can also be effectively kept on the central axis of the annular cutter 82 and the rotating drum 52. Then, the end of the cable body 1 is connected to the traction winding mechanism 3 through a lead wire. Simultaneously, the main cable 1 is mounted on the elastic lifting bracket 81, and the elastic lifting bracket 81 is pressed down by gravity, causing the support spring to stretch and generate a rebound force. During this process, the descending elastic lifting bracket 81 pushes the slide along the fixed guide rail 83 away from the rotating wrapping mechanism 5 through the inclined second linkage plate 87. The annular cutter 82 also drives the linkage ring 85 to move synchronously. The linkage ring 85 abuts against the extrusion block 545. At this time, the extrusion block 545 opens the corresponding clamping block 543 through the two first linkage plates 544 to keep them separated, so that the self-luminous strip 2 can freely pass through the two clamping blocks 543.

[0039] Then, the end of the self-luminous tape 2 on the luminous tape drum 53 in the rotating wrapping mechanism 5 is bonded to the surface of the cable body 1, and the cable body 1 is pulled laterally through the rotating wrapping mechanism 5 by the traction winding mechanism 3. At the same time, the rotating drum 52 of the rotating wrapping mechanism 5 rotates at a set speed. Thus, with the starting end of the self-luminous tape 2 bonded to the cable body 1, as the rotating drum 52 continues to rotate, the self-luminous tape 2 is wound along the length of the cable body 1. During this process, the self-luminous tape 2 is continuously released from the rotatable luminous tape drum 53.

[0040] During the lateral movement of the cable body 1 and the winding of the self-illuminating tape 2, once the end of the cable body 1 disengages from the elastic lifting bracket 81, the elastic lifting bracket 81 instantly springs up due to the rebound force of the support spring. At the same time, the annular cutter 82 also moves laterally and impacts the position of the self-illuminating tape 2 due to the rebound force released by the storage spring 86. During this process, the linkage ring 85 moves synchronously to disengage from the clamping block 543. Thus, the two clamping blocks 543 clamp each other in the middle under the rebound force of the corresponding limit spring 542, thereby fixing the position of the self-illuminating tape 2 near the luminous tape drum 53 and keeping it stable. Then, under the punching action of the annular cutter 82, the self-illuminating tape 2 can be automatically cut off, and the machine can be stopped wirelessly. Due to the shape of the annular cutter 82, the cutting can be effectively completed no matter where the self-illuminating tape 2 finally rotates and stops.

[0041] Furthermore, when the cable body 1 wrapped with the self-luminous tape 2 passes through the annular tube 72, the hot air generated by the hot air blower 71 is delivered to the circumferentially distributed hot air nozzles 73 through the annular tube 72. The hot air nozzles 73 blow the high-pressure, high-temperature air circumferentially onto the cable body 1. The heat-curing adhesive layer of the inner layer of the self-luminous tape 2, heated by the hot air nozzles 73, becomes sticky. Then, the clamping rollers 63 of the corresponding central clamping support mechanism 6 roll the adhesive to ensure the bonding effect, thus facilitating long-term use in underwater environments.

[0042] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
