Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a new energy wind power cable. Background Art

[0002] New energy cables can be roughly divided into: photovoltaic cables, wind power cables, cables for offshore oil platforms, cables for nuclear power plants, electric locomotive cables, cables for inland conventional and unconventional natural gas development, etc., but new energy cables have many shortcomings. Wind power photovoltaic cables are mostly outdoors and are affected by the wind and other environmental factors. The cables often swing and twist, and are prone to breakage, which increases the maintenance burden of personnel. In addition, when the cables are aged, damaged, maintained, and connected, they need to be stripped. Due to the influence of the materials, the cables are difficult to cut and it is difficult to strip without damaging the cable core. Secondly, people are required to carry cable stripping equipment and climb up the cable connection rack, which increases the danger of the connection work. In order to avoid the above technical problems, it is necessary to provide a new energy wind power cable to overcome the defects in the prior art. Summary of the invention

[0007] The stripping assembly includes a support ring, a fixing mechanism arranged on the support ring, a storage seat that slides circumferentially along the front ring end surface of the support ring, and a stripping knife arranged inside the storage seat. The upper end of the storage seat is provided with a cutting mechanism connected to the stripping knife, and the cutting mechanism is provided with scale lines.

[0008] The beneficial effects of the present invention are:

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1As shown, a new energy wind power cable comprises a cable core 1, an insulating layer 2 wrapped outside the cable core 1, a wrapping tape 3 wrapped outside the insulating layer 2, a flame retardant layer 4 wrapped outside the wrapping tape 3, an armor shielding layer 5 wrapped outside the flame retardant layer 4, and a wear-resistant thick sheath 6 wrapped outside the armor shielding layer 5. The present invention enhances the mechanical function of the cable by providing a thicker wear-resistant thick sheath 6 to improve the safety of use.

[0020] When stripping the above-mentioned new energy wind power cable, a stripping component is used, such as Figure 2 As shown, the stripping assembly includes a support ring 7, a fixing mechanism arranged on the support ring 7, a storage seat 15 that slides circumferentially along the front ring end surface of the support ring 7, and a stripping knife 16 arranged inside the storage seat 15. The upper end of the storage seat 15 is provided with a cutting mechanism connected to the stripping knife 16, and the cutting mechanism is provided with a scale line 22. The stripping principle of the present invention is: the thickness dimension data of the wear-resistant thick sheath 6 outside the cable is known. When stripping, the stripping knife 16 first contacts the wear-resistant thick sheath 6 outside the cable, and the value on the scale line 22 corresponding to the top plane of the storage seat 15 at this time is recorded. The thickness dimension data of the wear-resistant thick sheath 6 is added to the value at this time, which is the set value. The stripping knife 16 cuts downward. When the value on the scale line 22 corresponding to the top plane of the storage seat 15 is the set value, it means that the stripping knife 16 strips all the wear-resistant thick sheath 6. If the set value is exceeded, the internal structure of the cable will be damaged.

[0021] like Figure 3 As shown, as a further improvement of the present embodiment, the fixing mechanism includes six built-in grooves 8 provided on the inner ring surface of the support ring 7 and distributed in the circumferential direction, six threaded holes 9 provided on the support ring 7 and corresponding to the six built-in grooves 8, six arc plates 10 are provided in the six built-in grooves 8, six threaded rotating rods 11 are provided in the six threaded rotating holes 9, and the inner ends of the six threaded rotating rods 11 are rotatably connected to the six arc plates 10. The outer ends of the six threaded rotating rods 11 are fixedly connected to a rotating block 12. The threaded rotating rod 11 is rotated by the rotating block 12, so that the arc plate 10 is extended from the built-in groove 8 and pressed against the wear-resistant thick sheath 6 outside the cable, thereby realizing the fixed installation of the stripping assembly.

[0022] like Figure 4As shown, as a further improvement of this embodiment, an annular groove 13 is provided on the front ring end face of the support ring 7, a slide seat 14 is slidably installed in the annular groove 13, and the rear end face of the storage seat 15 is fixedly connected to the slide seat 14. The skinning knife 16 is connected to a skinning knife plate 17, and the skinning knife plate 17 is connected to the cutting mechanism. Two rotating levers 23 are symmetrically provided on both sides of the upper part of the storage seat 15. It is convenient for the storage seat 15 to rotate along the annular groove 13 for skinning.

[0023] like Figure 5 As shown, as a further improvement of this embodiment, the cutting mechanism includes a threaded rod 19 and two guide links 20 vertically arranged on the upper part of the storage seat 15, the bottom of the threaded rod 19 is rotatably connected to the skinning blade 17, the bottoms of the two guide links 20 are fixedly connected to the skinning blade 17, the top of the storage seat 15 is provided with a rotating wheel 21 coaxially connected to the threaded rod 19, and two scale lines 22 are provided, which are correspondingly arranged on the rod walls of the two guide links 20. Three vertically distributed through holes 18 are provided on the upper part of the storage seat 15, the threaded rod 19 and the two guide links 20 are correspondingly arranged in the three through holes 18, and the threaded rod 19 is located in the middle through hole 18. The through hole 18 corresponding to the threaded rod 19 is a threaded hole, and the rotating wheel 21 is rotatably installed on the top of the storage seat 15. When the rotating wheel 21 rotates to force the threaded rod 19 to rotate, the threaded rod 19 moves vertically downward under the threaded guidance of the through hole 18 that cooperates with it, thereby realizing the downward cutting action of the peeling knife 16.

[0024] like Figure 6 As shown, the stripping method of the new energy wind power cable is as follows: after the stripping assembly is sleeved on the cable and moved to the position where stripping is required, the threaded rotary rod 11 is rotated by the rotating block 12 to make the arc plate 10 extend from the built-in groove 8 and press against the outer surface of the cable to fix it, then, the rotating wheel 21 is rotated to force the threaded rod 19 to rotate, so that the stripping knife 16 extends from the storage seat 15 and presses against the wear-resistant thick sheath 6, then, the value on the scale line 22 corresponding to the top plane of the storage seat 15 is recorded at this time, plus the thickness size of the wear-resistant thick sheath 6 Data, calculate the set value, then make the stripping knife 16 cut radially downward into the wear-resistant thick sheath 6 to a certain size, and then turn the lever 23 to turn the storage seat 15 along the annular slide groove 13, so that the rotating stripping knife 16 rotates circumferentially for one circle of stripping, after cutting one circle, make the stripping knife 16 cut radially downward to a certain size, and rotate the stripping knife 16 again to rotate circumferentially for one circle of stripping, repeat several times until the value on the scale line 22 corresponding to the top plane of the storage seat 15 is the set value, which means that the stripping of the wear-resistant thick sheath 6 is completed.
