[0038] Working principle:

[0039] Embodiment 1

[0040] No passive air supply assembly is provided. For the stability of the whole device outside the pipe gallery corner 1, the T-shaped long screw 11 can be passed through the corresponding hole structure provided inside the support sleeve 2 and extended to the threaded hole preset on the surface of the pipe gallery corner 1 for detachable installation and fixing;

[0041] Next, according to the actual angle of the corridor corner 1 and the elastic deformation of the cable, the angle between the second guide frame plate 4 and the first guide frame plate 3 is adjusted, specifically, the disassembly limit screw 53 is turned to temporarily release the rotation limit of the adjustment shaft 51 and the linkage plate 52, and then the second guide frame plate 4 is turned to rotate and adjust the second guide frame plate 4 under the support of the linkage plate 52 and the adjustment shaft 51 until the angle between the second guide frame plate 4 and the first guide frame plate 3 meets the use requirements, the locking limit screw 53 is reset, and the friction plate 54 is used to re-limit the adjustment shaft 51 and the linkage plate 52. During the rotation adjustment of the second guide frame plate 4, the constraint sleeve plate 102 is synchronously rotated and adjusted with the second guide frame plate 4 under the guidance of the L-shaped curved rod 101 coaxial with the adjustment shaft 51;

[0042] Next, one end of the cable is put on the inner wall of the first guide frame plate 3 and passes through between the first fixed guide roller 6 and the first composite guide roller member 7. The first roller body 71 and the first guide cylinder 74 inside the first composite guide roller member 7 adaptively give way and clamp the cable under the elastic yield of the folded spring sheet 72 and the guidance of the first guide rod 73. Similarly, continue to move the cable so that it is put on the inside of the second guide frame plate 4 again and passes between the second fixed guide roller 8 and the second composite guide roller member 9. The second roller body 91 and the return spring 92 inside the second composite guide roller member 9 adaptively give way and clamp the cable under the elastic yield of the return spring 92 and the guidance of the second guide rod 93, thereby utilizing the curved limiting space formed between the first guide frame plate 3 and the second guide frame plate 4 for angular transmission.

[0043] Embodiment 2

[0044] A passive air supply component is provided. For the stability of the overall device outside the pipe gallery corner 1, a T-shaped long screw 11 can be passed through the corresponding hole structure provided inside the support sleeve 2 and extended to the preset threaded hole on the surface of the pipe gallery corner 1 for detachable installation and fixing;

[0045] Next, according to the actual angle of the corridor corner 1 and the elastic deformation of the cable, the angle between the second guide frame plate 4 and the first guide frame plate 3 is adjusted, specifically, the disassembly limit screw 53 is turned to temporarily release the rotation limit of the adjustment shaft 51 and the linkage plate 52, and then the second guide frame plate 4 is turned to rotate and adjust the second guide frame plate 4 under the support of the linkage plate 52 and the adjustment shaft 51 until the angle between the second guide frame plate 4 and the first guide frame plate 3 meets the use requirements, the locking limit screw 53 is reset, and the friction plate 54 is used to re-limit the adjustment shaft 51 and the linkage plate 52. During the rotation adjustment of the second guide frame plate 4, the constraint sleeve plate 102 is synchronously rotated and adjusted with the second guide frame plate 4 under the guidance of the L-shaped curved rod 101 coaxial with the adjustment shaft 51;

[0046] Next, one end of the cable is sleeved on the inner wall of the first guide frame plate 3 and passed between the first fixed guide roller 6 and the first composite guide roller member 7. The first roller body 71 and the first guide cylinder 74 inside the first composite guide roller member 7 adaptively give way and clamp the cable under the elastic yield of the folded spring sheet 72 and the guidance of the first guide rod 73. Similarly, the cable is continuously moved so that it is sleeved on the inside of the second guide frame plate 4 and passes between the second fixed guide roller 8 and the second composite guide roller member 9. The second roller body 91 and the return spring 92 inside the second composite guide roller member 9 adaptively give way and clamp the cable under the elastic yield of the return spring 92 and the guidance of the second guide rod 93. Thus, the curved limiting space formed between the first guide frame plate 3 and the second guide frame plate 4 is used for angular transmission.

[0047] During the reciprocating conveying of the cable, the passively rotating first fixed guide roller 6 and the second fixed guide roller 8 will drive the fan blades 14 to rotate synchronously through their corresponding transition shafts 13, and then generate airflow inside the two center hole sleeves 12, and then carry out designated transportation through two air pipes 15, pneumatically remove dust from the cables during transportation, increase the air flow rate in the first guide frame plate 3 and the second guide frame plate 4, and deform to achieve pneumatic cooling of the friction output structure such as the first fixed guide roller 6, the first composite guide roller member 7, the second fixed guide roller 8 and the second composite guide roller member 9, thereby optimizing the use effect.
