[0033] The technical features of the present invention are further described below with reference to the accompanying drawings and specific embodiments.

[0034] As shown in the figure, the present invention is an automatic stripping and rewinding device for the PE protective tape of medium- and high-voltage dynamic submarine cables. The device comprises a base 1 with a cable hole 14 in the middle for the passage of the medium- and high-voltage dynamic submarine cable. In this embodiment, the opening size of the cable hole 14 is significantly larger than the outer diameter of the cable to facilitate its passage. A rotation support portion protruding from the upper end surface of the base 1 is constructed in the middle of the base 1, and the cable hole 14 extends through the rotation support portion. The rotation support portion is constructed as a cylindrical metal cylinder and is fixedly welded to the base 1.

[0035] In this embodiment, a wear-resistant nylon pad 5 is provided to reduce wear caused by the slight shaking of the dynamic submarine cable conductor during the pulling process. Specifically, the wear-resistant nylon pad 5 has a double-layer structure. The outer surface is made of steel and fixed to the cable through-hole 14 by welding. The inner layer is made of nylon to prevent friction damage between the conductor and the device.

[0036] The base 1 is equipped with a PE tape rewinding and stripping mechanism. This mechanism includes a PE tape rotary base 2, a support rod 6, and a rotating take-up reel 7. The PE tape rotary base 2 is rotatably mounted on the base 1. The support rod 6 is mounted on the PE tape rotary base 2, with its upper end positioned above the upper opening of the cable feedthrough 14. When the PE tape rotary base 2 and the base 1 rotate relative to each other, the support rod 6 rotates synchronously around the cable feedthrough 14. The rotating take-up reel 7 is mounted on the support rod 6 and is rotatably connected to the support rod 6 via a rotating shaft.

[0037] The middle of the PE belt rotary seat 2 is provided with a rotation channel for the rotation support part to pass through. The rotation support part passes through the rotation channel. There is a bearing 3 between the rotation support part and the rotation channel, and the rotation support part and the rotation channel rotate relative to each other through the bearing 3.

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

[0039] The PE belt rotary rotating seat 2 is connected with a rotary power mechanism. The rotary power mechanism includes a speed reducer motor 12 and a transmission part 13, and the power output end of the speed reducer motor 12 is in transmission connection with the PE belt rotary rotating seat 2 through the transmission part 13.

[0040] In one embodiment of the present application, the cable through hole 14 is provided with a sensor 1401 for measuring the speed of the medium and high voltage dynamic submarine cable passing through the cable through hole 14. In this embodiment, the sensor 1401 can adopt a pulley type metering device. One side of the cable through hole 14 is provided with a vertical plate, and the sensor 1401 is installed 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 surface of the cable. The rolling direction of the pulley of the sensor 1401 is determined by the rotation axis of the pulley, and in this embodiment, the rotation axis of the pulley of the sensor 1401 is perpendicular to the moving direction of the medium and high voltage dynamic submarine cable.

[0041] In one embodiment of the present application, the signal output end of the sensor 1401 is electrically connected with the control input end of the speed reducer motor 12. The rotation is generated by the friction between the pulley and the conductor with PE protection belt, so as to be linked with the metering sensor, the running speed of the conductor is obtained, and then the speed of the rotary take-up wheel is adjusted and matched. At the same time, the contact between the pulley and the conductor can ensure that the cable runs stably without shaking during the stripping process.

[0042] In one embodiment, the transmission part 13 is a transmission belt. In other embodiments of the present application, the transmission part 13 can be selected from one of a transmission gear and a transmission chain.

[0043] In one embodiment, the middle and lower sections of the support rod 6 have a connecting rod, the rotary take-up wheel 7 is installed on the connecting rod and is in rotary connection with the connecting rod, and the end of the connecting rod is hinged to the support rod 6.

[0044] In one embodiment, the rotary take-up wheel 7 is a circular ring structure in the middle and is internally provided with a hole for installing a rotary bearing, the connecting rod passes through the hole and is in rotary connection with the rotary take-up wheel 7 through the rotary bearing. When the PE belt rotary rotating seat 2 rotates relative to the base 1, the rotary take-up wheel 7 is in contact with the track on the base 1 and rotates frictionally along the track. One end of the rotary take-up wheel 7 is provided with a rod-shaped structure for winding and releasing the PE belt, and the rod-shaped structure is sleeved on the connecting rod and moves with the rotary take-up wheel 7.

[0045] The middle section of the connecting rod and the support rod 6 have a spring 15, which can adjust the tension when the rotating take-up wheel 7 is taking up and releasing the PE tape.

[0046] The two ends of the spring 15 are connected with the connecting rod and the support rod 6 respectively. The middle and lower section of the support rod 6 is fixed with a spring tension control rod 9, which is provided with a strip-shaped through hole extending along the length direction of the spring tension control rod 9. The end of the spring 15 is connected with a sliding pin, the end of which passes through the strip-shaped through hole of the spring tension control rod 9 and slides along the strip-shaped through hole; the end of the sliding pin passing through the strip-shaped through hole is provided with an expanded end, the size of which is larger than the opening width of the strip-shaped through hole.

[0047] The top end of the support rod 6 is installed with a PE tape support rod 11, the upper end of which is provided with an arc-shaped support part.

[0048] The middle and upper section of the support rod 6 is installed with a tape pushing controller 10, which is constructed as L-shaped. One end of the tape pushing controller 10 is connected with the middle and upper section of the support rod 6, and the other end of the tape pushing controller 10 is perpendicular to the support rod 6.

[0049] In one embodiment of the present application, the support rod 6 is provided with a strip-shaped through hole, the length extension direction of which is arranged along the axial direction of the support rod 6. The end of the PE tape support rod 11 and the tape pushing controller 10 are connected in the strip-shaped through hole of the support rod 6 through bolt and nut structure.

[0050] The PE tape support rod 11 and the tape pushing controller 10 are control structures for controlling the direction of the PE tape. Taking the stripping of the PE tape from the dynamic submarine cable conductor as an example, the wire passes through the PE tape support rod 11 and then passes through the tape pushing controller 10 and is finally wound on the rotating take-up wheel 7. The rectangular threaded hole on the support rod 6 can adjust the position of the tape pushing controller 10 and the PE tape support rod 11, thereby realizing the control of the tension of the PE tape in the stripping and rewinding process.

[0051] In one embodiment of the present application, the tape pushing controller 10 is installed with a sensor three 1403, which can be a tension sensor. The measuring end of the sensor three 1403 can have a measuring part for the PE tape to pass through, which can monitor the tension of the PE tape in real time when it is stripped, so as to prevent the PE tape from being broken due to too large tension or the stripping from failing due to too small tension.

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