[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the 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.

[0023] Please refer to 1-10, an ultra-precision detection computer cable for a substation, which includes an inner supporting layer 1, a conductor 11, a shielding layer 12 and an outer sheath 14 from the inside to the outside, 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, and 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 with the outer sheath 14 through 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 prevent the shielding layer 12 and the outer sheath 14 from contacting and squeezing each other when slightly bent, and avoid the shielding layer 12 and the outer sheath 14 from being squeezed and contacted due to slight bending, resulting in reduced shielding effect and affecting the transmission stability of the cable.

[0024] 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 arranged 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, and the inner supporting layer 1 is a hollow structure. By arranging the partition 15, when the cable is bent, it is possible to avoid contact and extrusion of each group of conductors 11, which would cause mutual interference. After bending, the hollow structure arranged on the inner supporting layer 1 can be used to push the conductors 11 away when the cable is straightened after bending through the reset of the hollow structure. Not only can the conductors 11 be separated by the partition 15, but excessive extrusion between the conductor 11 and the partition 15 can also be avoided through the reset of the hollow structure.

[0025] A super-precision detection computer cable assembly for a substation, which is used to protect the above-mentioned super-precision detection computer cable for a substation, comprises a protective tube 2, a winding rod 21 is fixedly arranged on the protective tube 2, end covers 3 are rotatably arranged at both ends of the protective tube 2, a guide rod 31 is fixedly arranged on the end cover 3, a rotating ring 33 is fixedly arranged on the guide rod 31, and the rotating ring 33 is rotatably connected to the protective tube 2; a sliding block 34 is slidably arranged on the guide rod 31, and a plurality of rotating columns 35 are rotatably arranged on the sliding block 34; a first protrusion 36 is fixedly arranged on the sliding block 34, a spiral groove 22 is arranged on the protective tube 2, and the first protrusion 36 is slidably arranged in the spiral groove 22, by arranging the winding rod 21 in the protective tube 2, the cable is wound on the winding rod 21, and the excess length of the cable is protected by the protective tube 2, and when the cable is adjusted, the end cover 3 is rotated to make the guide rod 31 rotate with the sliding block 34, and the cable is taken out from the winding rod 21 The upper part is loosened and removed, so as to adjust the length of the cable extending from the two 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, so as to facilitate the adjustment of the cable length on both sides of the protective tube 2. The cable passes through the sliding block 34, and a plurality of 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.

[0026] In an embodiment further provided by the present invention, a wire pressing rod 32 is arranged 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 setting 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 phenomenon that the cable on the entire winding rod 21 becomes loose due to its own elasticity when the cable is relaxed, thereby improving the stability of the cable on the winding rod 21.

[0027] Furthermore, it also includes a traction member, which is used to pull the cable when the cable is wound and released; the traction member includes two traction wheels 4 rotatably arranged on the end cover 3, a connecting rope 41 is arranged between one of the traction wheels 4 and the sliding block 34, and the two ends of the connecting rope 41 are respectively fixedly connected to the traction wheel 4 and the sliding block 34, 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 extension length of the cable.

[0028] A volute 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 action of the volute 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 volute 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 of the end cover 3 and the sliding block 34, the cable retracted into the protective tube 2 is rolled onto the winding rod 21, which greatly improves the portability of the cable during the process of loosening and retracting.

[0029] Furthermore, a clamping block 5 is slidably provided on the end cover 3, a first oblique groove 51 is provided on the clamping block 5, a sliding ring 7 is slidably 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 slidably provided in the first oblique groove 51. By providing two clamping blocks 5, after the cable adjustment is completed, the two clamping blocks 5 are used to clamp the cable 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.

[0030] An abutment column 6 is slidably 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 frictional contact with the protective tube 2; a second inclined 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 slidably provided in the second inclined groove 62. By sliding the abutment column 6, the friction plate 61 is abutted against the protective tube 2, and the fixation between the end cover 3 and the protective tube 2 is completed. By controlling the sliding of the cross bar 71, the round rod 73 is matched with the second inclined 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.

[0031] 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 the rotating sleeve 9 is rotated, the push-pull ring 81 is driven, and the sliding ring 7 is controlled by the push-pull ring 81, so that the sliding ring 7 slides with the cross bar 71.

[0032] 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 clamping block 5 slides and opens through the cooperation between the second protrusion 72 and the first inclined groove 51 to release the clamping of the cable. At the same time, the abutment column 6 slides through the cooperation between 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 released from the winding rod 21, and under the cooperation of the first protrusion 36 and the spiral groove 22 During the rotation of the sliding block 34 with the guide rod 31, the sliding block 34 slides on the guide rod 31 at the same time. While the sliding block 34 slides, the connecting rope 41 is pulled to make the traction wheel 4 rotate against the force of the spiral spring 42. The loosened cable is sent out of the protective tube 2 by the rotation of the traction wheel 4 to facilitate the adjustment of the cable. In addition, 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 by the traction wheel 4. When the cable is put 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 make the clamping block 5 clamp the cable, and the friction plate 61 abuts against the protective tube 2.
