Referring now to fig. 1 and 2 in combination, the present invention provides a submarine cable longitudinal wrapping apparatus 10 comprising: a mounting sleeve 110, the mounting sleeve 110 being configured to be capable of being penetrated and slid by the inner conductor 70 and being penetrated and slid by the water blocking tape 60; and a telescopic structure 160, wherein a first end of the telescopic structure 160 is connected with the installation sleeve 110, the telescopic structure 160 is configured to fix the installation sleeve 110 in a squirrel cage structure formed by matching the fixing plate 50, the screw rod 30 and the branching plate 20, a second end of the telescopic structure 160 is connected with the fixing plate 50, and the telescopic structure 160 is further configured to provide an installation space for startup production and debugging of the stranded monofilaments 80 in a telescopic manner.
The twisting of the outer conductor 90 is achieved by the fixing plate 50, the lead screw 30 and the branching plate 20, and the outer conductor 90 is formed by twisting the monofilament 80 in a spiral winding manner, specifically: the twisted monofilaments 80 pass through the wire dividing plate 20, the inner conductor 70 passes through the fixed plate 50, the screw rod 30 and the wire dividing plate 20 to form a squirrel cage structure, the inner conductor 70 moves along the axial direction of the squirrel cage structure, meanwhile, the wire dividing plate 20 is rotated, and the wire dividing plate 20 drives the twisted monofilaments 80 to be spirally wound on the periphery of the inner conductor 70 to form the outer conductor 90. In general, at least two stranded monofilaments 80 are led out from a wire stranding machine pay-off reel, each stranded monofilament 80 passes through a threading die arranged on the outer wall of the wire dividing plate 20, and the stranded monofilaments 80 are uniformly distributed along the circumferential direction of the wire dividing plate 20, so that the cross-sectional area of the outer layer conductor 90 is larger, and the effect of realizing functions is better.
In this embodiment, the squirrel cage structure is a structure in the twisting device of the outer conductor 90, the telescopic structure 160 fixes the installation sleeve 110 in the squirrel cage structure, the installation sleeve 110 installs the inner conductor 70 and the water blocking tape 60 in the squirrel cage structure, the inner conductor 70 passes through the installation sleeve 110, the twisted monofilaments 80 passing through the branching plate 20 are located on the outer periphery of the inner conductor 70 and keep a distance from the inner conductor 70, the water blocking tape 60 can be wound along with the spiral of the twisted monofilaments 80 and wrapped on the outer periphery of the inner conductor 70 in the processes of moving the inner conductor 70 and rotating the branching plate 20, and the twisted monofilaments 80 are spirally wound on the outer periphery of the water blocking tape 60. Because the submarine cable longitudinal wrapping device 10 is close to the conductor twisting head 40, the water blocking yarns are not required to be used for binding the water blocking tape in the longitudinal wrapping process of the water blocking tape 60, the cost of purchasing the water blocking yarns is saved, and the consumption of the water blocking yarns is reduced by 100%. In the longitudinal wrapping water blocking tape and water blocking yarn binding mode in the prior art, the longitudinal wrapping of the water blocking tape 60 is far away from the conductor twisting head 40, the water blocking yarn is required to be bound in the middle, gaps or deviation are prevented when the water blocking tape 60 wraps the inner conductor 70 before the outer conductor 90 is prepared, the process of twisting the monofilaments 80 to form the outer conductor 90 is a necessary process for manufacturing the submarine cable, on the basis, the step of water blocking yarn binding is omitted, and the longitudinal wrapping and replacement time of the water blocking tape 60 is saved. In addition, the submarine cable longitudinal wrapping device 10 is small in occupied space, simple to operate, simple to install, convenient to replace the mounting sleeve 110, adjustable in size, wide in diameter range applicable to the inner conductor 70, capable of being rapidly produced and debugged through the telescopic structure 160, effectively improved in production efficiency and saved in manufacturing cost.
The telescopic structure 160 is shortened, the mounting sleeve 110 is driven to move towards the direction close to the fixed plate 50, a space is provided for startup production debugging of the stranded monofilaments 80, and interference caused by the mounting sleeve 110 to the debugging of the stranded monofilaments 80 is prevented; the telescopic structure 160 stretches to drive the installation sleeve 110 to move in a direction away from the fixing plate 50, so that the installation sleeve 110 approaches to the direction of the twisting starting point of the twisted monofilaments 80, and when the twisted monofilaments 80 are spirally wound, the water blocking tape 60 can be completely attached to the whole outer surface of the inner conductor 70, and the water blocking tape 60 can be tightly coated on the surface of the inner conductor 70.
Compared with the conventional longitudinal wrapping water blocking tape and water blocking yarn binding mode, in this embodiment, since the submarine cable longitudinal wrapping device 10 is very close to the conductor twisting head 40, when the twisted monofilaments 80 are spirally wound, the water blocking tape 60 can be rapidly and completely attached to the whole outer surface of the inner layer conductor 70 without considering the width allowance of the water blocking tape 60. In the conventional longitudinal wrapping water blocking tape and water blocking yarn binding mode, as the distance between the water blocking tape 60 and the conductor twisting head 40 is far, the width allowance of the water blocking tape 60 needs to be considered in order to ensure the stable wrapping of the water blocking tape 60, and in general, the water blocking tape 60 consumption is reduced, and particularly, the water blocking tape is reduced by 20%.
Specifically, the mounting sleeve 110 has a cylindrical structure for mating with the cylindrical structure of the inner conductor 70 to facilitate the penetration and sliding of the inner conductor 70, and the inner diameter of the mounting sleeve 110 is 3mm to 6mm larger than the diameter of the inner conductor 70.

The sleeve 162 and the movable rod 161 are both rigid and horizontally arranged, so that on one hand, the relative positions of the fixed plate 50 and the mounting sleeve 110 in the horizontal direction are always the same before and after extension and retraction; on the other hand, the mounting sleeve 110 can be stably supported, and the stability of the mounting sleeve 110 is ensured in the longitudinal wrapping process.

In another embodiment, two telescopic structures 160 are provided, which are respectively located at two sides of the mounting sleeve 110, so as to improve the stability of the mounting sleeve 110, ensure that the inner conductor 70 can always move along the horizontal direction, and prevent that the single telescopic structure 160 cannot support the mounting sleeve 110 and the inner conductor 70, i.e. prevent the inner conductor 70 from bending the telescopic structure 160.

The adjusting member 130 is different from the screwing depth of the adjusting cover 120, and correspondingly changes the installation volume inside the adjusting cover 120, namely, the adjusting member 130 is screwed towards the direction inside the adjusting cover 120, so that the installation volume of the adjusting cover 120 is reduced, the adjusting member 130 is screwed towards the direction outside the adjusting cover 120, and the installation area of the adjusting cover 120 is increased. The submarine cable longitudinal packing apparatus 10 further includes a first connection plate fixed to the outer wall of the adjustment housing 120, and a movable rod 161 of the telescopic structure 160 is connected to the first connection plate.

The submarine cable longitudinal packing device 10 in the waterproof tape longitudinal packing device has the same technical scheme and technical effect as the submarine cable longitudinal packing device 10, and is not described herein.
Referring to fig. 1 to 4 in combination, the present invention provides a method for using a water-blocking tape longitudinal wrapping apparatus, which is implemented by the water-blocking tape longitudinal wrapping apparatus, and includes the following steps: passing the inner conductor 70 through the mounting sleeve 110, and passing one end of the inner conductor 70 through the conductor twisting head 40, the inner conductor 70 being divided into a first section, which is a portion of the inner conductor 70 passing through the conductor twisting head 40, and a second section, which is a portion not passing through the conductor twisting head 40; the stranded monofilaments 80 are led out from a wire stranding machine paying-off reel and pass through the wire stranding plate 20, and one end of each stranded monofilament 80 passes through the conductor stranding head 40 and then is spirally wound on the inner conductor 70; pre-fixing at least part of the water blocking tape 60 and the second section of the inner conductor 70, so that at least part of the water blocking tape 60 is attached to the lower surface of the second section of the inner conductor 70; the inner conductor 70 is moved toward the conductor twisting head 40 while the wire dividing plate 20 is rotated, the water blocking tape 60 is coated on the surface of the inner conductor 70 by the twisted monofilaments 80, and the outer conductor 90 is formed after passing through the conductor twisting head 40 by the twisted monofilaments 80 spirally wound on the outer surface of the water blocking tape 60.
In this embodiment, the inner conductor 70 is selected to have a suitable inner diameter of the mounting sleeve 110 before passing through the mounting sleeve 110, and the selected mounting sleeve 110 is secured within the adjustment housing 120. The outer layer conductor 90 formed by spirally winding a layer of stranded monofilament 80 on the outer surface of the first section of the inner layer conductor 70, so that the stranded monofilament 80 and the inner layer conductor 70 are pre-fixed, and the subsequent stranded monofilament 80 can be smoothly and completely spirally wound on the outer surface of the water-blocking tape 60.
Specifically, the water blocking tape 60 and the inner conductor 70 are pre-fixed in the following manner: the end of the water blocking tape 60 is wound and fixed on the surface of the inner conductor 70 by an adhesive tape, so that the water blocking tape 60 is not separated from the inner conductor 70, and the water blocking tape 60 can move synchronously with the inner conductor 70 under the driving of the inner conductor 70. During the twisting process of the twisted monofilaments 80, the angle of the water blocking tape 60 entering the guide cylinder 150 is adjusted in real time, so that the water blocking tape 60 can be completely coated on the surface of the inner conductor 70.
Referring to fig. 1 to 3 in combination, in one embodiment of the present invention, before the step of passing the stranded monofilament 80 through the conductor stranding head 40, that is, during startup production and commissioning, the method for longitudinally wrapping the water blocking tape 60 further includes: controlling the telescopic structure 160 to shorten so that the distance between the end of the mounting sleeve 110 facing the conductor twisting head 40 and the inlet of the conductor twisting head 40 increases; after one end of the twisted monofilament 80 passes through the conductor twisting head 40 and is spirally wound around the inner conductor 70, the extension and contraction structure 160 is controlled to extend so that the distance between the end of the mounting sleeve 110 toward the conductor twisting head 40 and the entrance of the conductor twisting head 40 is reduced.
In this embodiment, the telescopic structure 160 functions to adjust the distance between the mounting sleeve 110 and the conductor twisting head 40. Before the water blocking tape 60 is longitudinally wrapped, it is necessary to first install the twisted monofilaments 80 on the splitter plate 20, and spirally wind one end of the twisted monofilaments 80 on the first section of the inner conductor 70 and pass through the conductor twisting head 40, which requires a large operation space, and at this time, the distance between the installation sleeve 110 and the conductor twisting head 40 is increased by the telescopic structure 160, so that sufficient space is provided for the operation of the twisted monofilaments 80, and the installation sleeve 110 is prevented from interfering with the implementation of the operation. After the stranded monofilament 80 is spirally wound on the first section of the inner conductor 70, the longitudinal wrapping operation of the water blocking tape 60 is started, at this time, the distance between the mounting sleeve 110 and the conductor twisting head 40 is reduced by the telescopic structure 160, so that the water blocking tape 60 located between the mounting sleeve 110 and the conductor twisting head 40 still maintains the semi-wrapped state on the surface of the inner conductor 70, and the stranded position of the stranded monofilament 80 is between the mounting sleeve 110 and the conductor twisting head 40, so that the stranded monofilament 80 can ensure that the upper surface of the water blocking tape 60 can be completely attached to the surface of the inner conductor 70, and if the distance between the mounting sleeve 110 and the conductor twisting head 40 is too large in the longitudinal wrapping process, the water blocking tape 60 can be spread again, even a horizontal state is formed, and in this state, the stranded monofilament 80 cannot be ensured to be completely attached to the upper surface of the water blocking tape 60 to the surface of the inner conductor 70.
