Description

Technical Field

[0001] This utility model relates to an automatic stripping and rewinding device for the PE protective tape of medium and high voltage dynamic submarine cables, belonging to the field of cable equipment. Background Technology

[0002] my country's offshore wind power has entered a new era of rapid development, with projects gradually moving towards more distant sea areas, larger-scale wind turbines, and greater total installed capacity. Currently, traditional cable systems can no longer meet the demands of future offshore wind power development. With the continuous increase in offshore wind turbine capacity and the sustained rise in total installed capacity of wind farms, coupled with surging market demand and strong policy support, the voltage level of dynamic submarine cables is constantly increasing, and China is continuously breaking through new technological barriers.

[0003] Dynamic submarine cables must withstand extreme conditions in deep seas and the dynamic stress between floating platforms and static cables, requiring high-strength mechanical structures, fatigue-resistant materials, and corrosion-resistant technologies to ensure long-term stable operation. Therefore, medium- and high-voltage cable conductors must balance high conductivity, fatigue resistance, water resistance, and dynamic adaptability. Their production relies on high-purity materials, precision processes, and comprehensive quality control, making their technical threshold significantly higher than conventional cables. Besides strict control over the appearance during the production process, wear protection measures for the conductors are also essential during the dynamic submarine cable manufacturing process. Currently, the mainstream industry solution is to manually wrap a special PE protective tape immediately after the conductor stranding process. This innovative process design effectively prevents mechanical wear and stress deformation during the winding process and isolates environmental pollutants during manufacturing. This protective layer will be precisely peeled off before the subsequent three-core co-extrusion process of conductor shielding, insulation layer, and insulation shielding layer, ensuring a perfect combination of the multi-layer structure. However, manual wrapping and peeling of the PE protective tape is inefficient, costly, and prone to human error leading to surface wear. Utility Model Content

[0033] The technical features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] As shown in the figure, this utility model is an automatic stripping and rewinding device for the PE protective tape of medium- and high-voltage dynamic submarine cables, including a base 1. The base 1 has a cable through-hole 14 in the middle for the medium- and high-voltage dynamic submarine cable to pass through. In this embodiment, the opening size of the cable through-hole 14 is much larger than the outer diameter of the cable, so that the cable can pass through easily. A rotating support part protruding from the upper end face of the base 1 is constructed in the middle of the base 1, and the cable through-hole 14 passes through the rotating support part. The rotating support part is constructed as a cylindrical metal cylinder and is fixedly welded to the base 1.

[0035] In this embodiment, an anti-abrasion nylon pad 5 is provided to reduce the wear caused by slight shaking of the dynamic submarine cable conductor during pulling, which would otherwise lead to wear in contact with the device. Specifically, the anti-abrasion nylon pad 5 has a double-layer structure: the outer layer is made of steel and is fixed inside the cable through-hole 14 by welding, while the inner layer is made of nylon to prevent friction damage between the conductor and the device.

[0036] A PE tape rewinding and peeling mechanism is provided on the base 1. The PE tape rewinding and peeling mechanism includes a PE tape rotating seat 2, a support rod 6, and a rotating take-up wheel 7. The PE tape rotating seat 2 is rotatably mounted on the base 1. The support rod 6 is mounted on the PE tape rotating seat 2, with its upper end higher than the upper opening of the cable through-hole 14. When the PE tape rotating seat 2 rotates relative to the base 1, the support rod 6 rotates synchronously around the cable through-hole 14. The rotating take-up wheel 7 is mounted on the support rod 6 and rotatably connected to the support rod 6 via a rotating shaft.

[0037] The PE belt rotating base 2 has a rotating channel in the middle for the rotating support to pass through. The rotating support passes through the rotating channel, and there is a bearing 3 between the rotating support and the rotating channel, through which they rotate relative to each other.

[0038] In this embodiment, the counterweight base 4 is a square metal frame structure, and three support columns are provided under the base 1. The support columns are fixed to the counterweight base 4 by welding. The base 1 is provided with a circular track, which is arranged around the cable through hole 14. The track is used to control the sliding trajectory of the rotating take-up wheel 7. When the PE belt rotating seat 2 rotates relative to the base 1, the rotating take-up wheel 7 contacts the track and moves along the track.

[0039] The PE belt rotary base 2 is connected to a rotary power mechanism. The rotary power mechanism includes a geared motor 12 and a transmission part 13. The power output end of the geared motor 12 is connected to the PE belt rotary base 2 through the transmission part 13.

[0040] In one embodiment of this application, a sensor 1401 is provided at the cable through-hole 14 to measure the speed at which a medium-high voltage dynamic submarine cable passes through the cable through-hole 14. In this embodiment, the sensor 1401 can be a pulley-type meter counter. A vertical plate is provided on one side of the cable through-hole 14, and the sensor 1401 is mounted on the surface of the vertical plate facing the cable through-hole 14. When the cable passes through the cable through-hole 14, the pulley of the sensor 1401 rolls in contact with the cable surface. The rolling direction of the pulley of the sensor 1401 is determined by the rotation axis of the pulley. In this embodiment, the rotation axis of the pulley of the sensor 1401 is set perpendicular to the movement direction of the medium-high voltage dynamic submarine cable.

[0041] In one embodiment of this application, the signal output terminal of sensor 1401 is electrically connected to the control input terminal of geared motor 12. Rotation is generated by the friction between the pulley and the conductor with the PE protective strip, thereby linking with the meter sensor to obtain the conductor's running speed. The speed of the rotating take-up pulley is then adjusted to match this speed. Simultaneously, the contact between the pulley and the conductor ensures stable cable operation without swaying during the stripping process.

[0042] In one embodiment, the transmission part 13 is a transmission belt. In other embodiments of this application, the transmission part 13 may be selected from transmission gears or transmission chains.

[0043] In one embodiment, the lower middle section of the support rod 6 has a connecting rod, and a rotating take-up wheel 7 is mounted on the connecting rod and rotatably connected to the connecting rod. The end of the connecting rod is hinged to the support rod 6.

[0044] In one embodiment, the rotating take-up pulley 7 has a circular structure in the middle and an internal hole for mounting a rotating bearing. The connecting rod passes through this hole and rotates on the connecting rod via the rotating shaft bearing. When the PE belt rotating seat 2 rotates relative to the base 1, the rotating take-up pulley 7 contacts the track on the base 1 and rotates along the track due to friction. One end of the rotating take-up pulley 7 has a rod-shaped structure for winding and releasing the PE belt. The rod-shaped structure is sleeved on the connecting rod and moves with the rotating take-up pulley 7.

[0045] A spring 15 is located between the middle section of the connecting rod and the support rod 6. The spring 15 can adjust the tension when the PE belt is wound up and released by rotating the take-up pulley 7.

[0046] The two ends of spring 15 are connected to the connecting rod and the support rod 6, respectively. A spring tension control rod 9 is fixed in the lower middle section of the support rod 6. A strip-shaped through hole is formed on the spring tension control rod 9 along its length. A sliding pin is connected to the end of spring 15. The end of the sliding pin passes through the strip-shaped through hole on the spring tension control rod 9 and slides along the strip-shaped through hole. An expansion end is formed at the end of the sliding pin that passes through the strip-shaped through hole. The size of the expansion end is larger than the opening width of the strip-shaped through hole.

[0047] A PE belt support rod 11 is installed at the top of the support rod 6, and an arc-shaped support part is constructed at the upper end of the PE belt support rod 11.

[0048] A pull-tab controller 10 is installed on the upper middle section of the support rod 6. The pull-tab controller 10 is constructed in an L-shape. One end of the pull-tab controller 10 is connected to the upper middle section of the support rod 6, and the other end of the pull-tab controller 10 is set perpendicular to the support rod 6.

[0049] In one embodiment of this application, a strip-shaped through hole is provided on the support rod 6, and the length of the strip-shaped through hole extends along the axial direction of the support rod 6. The ends of the PE belt support rod 11 and the pull-tab controller 10 are connected to the strip-shaped through hole of the support rod 6 by a bolt and nut structure.

[0050] The PE tape support rod 11 and the tape puller 10 are control structures for controlling the direction of the PE tape. Taking the stripping of the PE tape from the conductor of a dynamic submarine cable as an example, the tape passes through the PE tape support rod 11, then through the tape puller 10, and finally winds onto the rotating take-up reel 7. The rectangular threaded hole on the support rod 6 can adjust the position of the tape puller 10 and the PE tape support 11, thereby controlling the tension of the PE tape during the stripping and rewinding process.

[0051] In one embodiment of this application, a sensor 1403 is installed on the tape release controller 10. The sensor 1403 can be a tension sensor. The measuring end of the sensor 1403 can have a measuring part through which the PE tape passes. The tension of the PE tape during peeling is monitored in real time by the sensor 1403 to prevent breakage due to excessive tension or peeling failure due to insufficient tension.

[0052] In one embodiment of this application, a sensor 1402 for measuring the thickness of the PE protective tape winding is provided on the rotating take-up wheel 7. The sensor 1402 can be a photoelectric sensor. The photoelectric sensor accurately detects the collection height of the wrapping tape and calculates the length of the wrapping tape through an algorithm to ensure that the collection length of the tape is effectively controlled.

[0053] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
