[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0041] Please refer to 1-10, an ultra-precision detection computer cable for substations, which includes, from the inside to the outside, an inner supporting layer 1, a conductor 11, a shielding layer 12 and an outer sheath 14. An outer supporting ring 13 is fixedly provided on the shielding layer 12, and a plurality of supporting points 17 are fixedly provided on the outer supporting ring 13. The plurality of supporting points 17 are fixedly connected to the outer sheath 14. By arranging the outer supporting ring 13 on the shielding layer 12 and fixing the outer supporting ring 13 and the outer sheath 14 with a plurality of supporting points 17, when the cable is slightly bent, the supporting effect of the supporting points 17 and the outer supporting ring 13 can avoid contact and extrusion between the shielding layer 12 and the outer sheath 14, thereby avoiding extrusion and contact between the shielding layer 12 and the outer sheath 14 due to slight bending, resulting in reduced shielding effect and affecting the transmission stability of the cable.

[0042] Specifically, a plurality of partitions 15 are fixedly arranged between the inner supporting layer 1 and the shielding layer 12, and a hollow portion 16 is provided on the partition 15; the conductor 11 includes four groups of twisted pairs, and each group of twisted pairs is separated by the partition 15. The inner supporting layer 1 is a hollow structure. By providing the partition 15, when the cable is bent, the contact and extrusion of each group of conductors 11 are avoided, resulting in mutual interference. After bending, the hollow structure provided on the inner supporting layer 1 allows the cable to be straightened after bending, and the conductors 11 are pushed away by the reset of the hollow structure. Not only are the conductors 11 separated by the partition 15, but excessive extrusion between the conductor 11 and the partition 15 can also be avoided by the reset of the hollow structure.

[0043] A super-precision detection computer cable assembly for substations, which is used to protect the above-mentioned super-precision detection computer cable for substations, includes a protective tube 2, a winding rod 21 is fixedly provided on the protective tube 2, end covers 3 are rotatably provided at both ends of the protective tube 2, a guide rod 31 is fixedly provided on the end cover 3, a rotating ring 33 is fixedly provided on the guide rod 31, and the rotating ring 33 is rotatably connected to the protective tube 2; a sliding block 34 is slidably provided on the guide rod 31, and a plurality of rotating columns 35 are rotatably provided on the sliding block 34; a first protrusion 36 is fixedly provided on the sliding block 34, a spiral groove 22 is provided on the protective tube 2, and the first protrusion 36 is slidably provided in the spiral groove 22, and the cable is wound on the winding rod 21 by arranging the winding rod 21 in the protective tube 2, and the excess length of the cable is protected by the protective tube 2, and when the cable is adjusted, the guide rod 31 is rotated with the sliding block 34 by rotating the end cover 3, and the cable is taken out of the winding rod 21. The upper part is loosened and removed, which makes it easier to adjust the length of the cables extending from both ends of the protective tube 2. During the rotation of the guide rod 31 and the sliding block 34, the sliding block 34 slides synchronously on the guide rod 31 with the cooperation of the first protrusion 36 and the spiral groove 22, so that the cable can be regularly loosened from the winding rod 21. Conversely, when the end cover 3 rotates in the opposite direction, the cable can be regularly collected into the protective tube 2 and regularly wound around the winding rod 21. The protective tube 2 is used to protect and collect the excess length of the cable during the cable laying process, and the cable is regularly wound around the winding rod 21. At the same time, through the rotation of the end cover 3, it is more convenient to collect the cable into the protective tube 2 or extend it from the protective tube 2, which facilitates the adjustment of the cable length on both sides of the protective tube 2; the cable passes through the sliding block 34, and the multiple rotating columns 35 rotatably arranged on the sliding block 34 are used to prevent excessive friction between the cable and the sliding block 34 during the adjustment process.

[0044] In an embodiment further provided by the present invention, a wire pressing rod 32 is provided between the end cover 3 and the rotating ring 33, and the two ends of the wire pressing rod 32 are rotatably connected to the end cover 3 and the rotating ring 33 respectively. By providing the wire pressing rod 32, when the cable is wound on the winding rod 21, the pressure of the wire pressing rod 32 on the cable can make the cable tightly wound on the winding rod 21, and when the cable is relaxed from the winding rod 21, the pressure of the wire pressing rod 32 on the cable on the winding rod 21 can avoid the cable on the entire winding rod 21 from becoming loose due to its own elasticity when the cable is relaxed, thereby improving the stability of the cable on the winding rod 21.

[0045] Furthermore, it also includes a traction member, which is used to pull the cable when the cable is wound and unwound; the traction member includes two traction wheels 4 rotatably arranged on the end cover 3, and a connecting rope 41 is provided between one of the traction wheels 4 and the sliding block 34, and the two ends of the connecting rope 41 are fixedly connected to the traction wheel 4 and the sliding block 34 respectively, and are wound around the traction wheel 4. When the end cover 3, the guide rod 31, and the sliding block 34 rotate, under the action of the first protrusion 36 and the spiral groove 22, the sliding block 34 slides on the guide rod 31. During the sliding process, the traction wheel 4 is rotated by pulling the connecting rope 41, and the cable released from the winding rod 21 is pulled out of the protective tube 2, so as to facilitate the adjustment of the extended length of the cable.

[0046] A spiral spring 42 is provided between the traction wheel 4 and the end cover 3. When the sliding block 34 pulls the connecting rope 41, the traction wheel 4 rotates to send the cable released from the winding rod 21 out of the protective tube 2. During this process, the traction wheel 4 rotates to overcome the force of the spiral spring 42. When the end cover 3 rotates in the opposite direction to retract the cable into the protective tube 2, the sliding block 34 resets and slides on the guide rod 31 to loosen the connecting rope 41. At this time, under the action of the spiral spring 42, the traction wheel 4 rotates to reel in the connecting rope 41, and at the same time, the cable outside the protective tube 2 is pulled into the protective tube 2, and under the rotation action of the end cover 3 and the sliding block 34, the cable retracted into the protective tube 2 is wound on the winding rod 21, which greatly improves the portability of the cable during the relaxation and retraction process.

[0047] Furthermore, a clamping block 5 is slidingly provided on the end cover 3, a first oblique groove 51 is provided on the clamping block 5, a sliding ring 7 is slidingly provided on the end cover 3, a cross bar 71 is fixedly provided on the sliding ring 7, a second protrusion 72 is fixedly provided on the cross bar 71, and the second protrusion 72 is slidingly provided in the first oblique groove 51. By setting two clamping blocks 5, after the cable adjustment is completed, the cable is clamped by the two clamping blocks 5 to ensure the stability of the cable after adjustment. At the same time, by controlling the sliding of the cross bar 71, the second protrusion 72 is matched with the first oblique groove 51, so that when the cross bar 71 slides, the clamping block 5 is controlled to clamp or release the cable.

[0048] An abutment column 6 is slidingly provided on the end cover 3, and a friction plate 61 is fixedly provided on the abutment column 6, and the friction plate 61 is in friction contact with the protective tube 2; a second oblique groove 62 is provided on the abutment column 6, and a round rod 73 is fixedly provided on the cross bar 71, and the round rod 73 is slidingly provided in the second oblique groove 62. By sliding the abutment column 6, the friction plate 61 is in abutment with the protective tube 2, completing the fixation between the end cover 3 and the protective tube 2. By controlling the sliding of the cross bar 71, the round rod 73 is matched with the second oblique groove 62, and the sliding of the abutment column 6 is controlled to control the contact and separation of the friction plate 61 on the abutment column 6 and the protective tube 2.

[0049] In an embodiment further provided by the present invention, a bolt 8 is threadedly provided on the end cover 3, a push-pull ring 81 is fixedly provided on the bolt 8, and the push-pull ring 81 is rotatably connected to the sliding ring 7; a rotating sleeve 9 is rotatably provided on the end cover 3, and when it rotates, it drives the push-pull ring 81 and controls the sliding ring 7 through the push-pull ring 81, so that the sliding ring 7 slides with the cross bar 71.

[0050] When laying and adjusting the cable, the bolt 8 is rotated to make the bolt 8 slide with the push-pull ring 81, the sliding ring 7, and the cross bar 71. During the sliding process, the second protrusion 72 cooperates with the first inclined groove 51, and the clamping block 5 slides open to release the clamping of the cable. At the same time, the abutment column 6 slides through the cooperation of the round rod 73 and the second inclined groove 62, and the friction plate 61 is separated from the protective tube 2. Then, the end cover 3 is rotated. During the rotation process, the end cover 3 rotates with the guide rod 31, the rotating ring 33, the wire pressing rod 32, and the sliding block 34. Under the action of the sliding block 34, the cable is loosened from the winding rod 21, and under the cooperation of the first protrusion 36 and the spiral groove 22 As the sliding block 34 rotates with the guide rod 31, it slides on the guide rod 31 at the same time. As the sliding block 34 slides, the connecting rope 41 is pulled, causing the traction wheel 4 to overcome the force of the spiral spring 42 and rotate. The loosened cable is sent out of the protective tube 2 through the rotation of the traction wheel 4 to facilitate cable adjustment. Moreover, as the sliding block 34 slides on the guide rod 31, the cable can be regularly loosened from the winding rod 21 and pulled out of the protective tube 2 through the traction wheel 4. When the cable is retracted into the protective tube 2, the end cover 3 can be rotated in the opposite direction. After the cable adjustment is completed, the bolt 8 is rotated to clamp the cable with the clamping block 5, and the friction plate 61 abuts against the protective tube 2.

[0051] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
