[0037] In order to solve the problem that the outer wall of the cable is easily dirty when it is installed, when the cable needs to be installed overhead, the fixing frame 1 can be installed in the cable trench first, and then the installation box 5 can be inserted into the installation groove 2 on the fixing frame 1. By setting the installation component, the installation box 5 and the lifting frame 4 can be installed on the fixing frame 1, and then the cable is placed on the lifting frame 4. By setting the arc groove 6 on the lifting frame 4, it is convenient to place the cable. After the cable is placed, the end of the cable can be pulled into the reserved cavity until the end of the cable is pulled into the power room. The end of the cable can be installed at a designated position in the power room. By setting the scraping assembly By setting a blow-off component, dirt on the outer wall of the cable can be scraped off when the cable is pulled, thereby preventing dirt from being attached to the outer wall of the cable; by setting a blow-off component, after the dirt on the outside of the cable is scraped off, a weak wind flow can be generated to blow off the debris remaining on the outside of the cable; by setting an air duct 37, the flowing air can be transferred to the ventilation slot 36; by setting a control component, the closing and opening of the air hole 34 can be controlled according to whether the lifting frame 4 is installed; by setting a ventilation component at the bottom of the installation box 5, the wind flow in the air hole 34 can be transferred to the inside of the lifting frame 4 after the air hole 34 is opened, thereby providing cooling and ventilation effects for the outside of the cable.

[0038] Reference Figure 2-3The scraping assembly includes a pulley 7, which is rotatably connected to one side of the lifting frame 4, a first bevel gear 8 is fixedly connected to one side of the pulley 7, a second bevel gear 9 is meshed on one side of the first bevel gear 8, a rotating rod 10 is fixedly connected to one side of the second bevel gear 9, and the rotating rod 10 is rotatably connected to the inner wall of the lifting frame 4, and a first gear 11 is fixedly connected to one end of the rotating rod 10 away from the second bevel gear 9, and the first gear 11 is arranged on the side of the lifting frame 4 away from the pulley 7, a gear ring 12 is meshed on one side of the first gear 11, and a soft brush 15 is fixedly connected to the inner wall of the gear ring 12, a limiting groove 14 is provided on one side of the gear ring 12, and an arc plate 13 is fixedly connected to one side of the lifting frame 4, and one end of the arc plate 13 is slidably connected to the inner wall of the limiting groove 14.

[0039] When the cable moves to one side, since the cable is arranged at the top of the pulley 7, the pulley 7 will be driven to rotate. When the pulley 7 rotates, the first bevel gear 8 on one side will be driven to rotate. When the first bevel gear 8 rotates, the second bevel gear 9 engaged on one side will be driven to rotate. When the second bevel gear 9 rotates, the rotating rod 10 on one side will be driven to rotate on the inner wall of the lifting frame 4, and the first gear 11 arranged at one end of the rotating rod 10 will also rotate with the rotating rod 10. When the first gear 11 rotates, the gear ring 12 engaged on one side will be driven to rotate. By arranging an arc plate 13 on one side of the lifting frame 4, the rotation of the gear ring 12 can be limited by sliding the arc plate 13 in the limiting groove 14 when the gear ring 12 rotates. Since a soft brush 15 is arranged inside the gear ring 12, the gear ring 12 will drive the soft brush 15 to rotate when it rotates, so that the dirt on the surface of the cable can be scraped off.

[0040] Reference Figure 4-6 The blowing assembly includes a side ring 16, which is fixed to the side of the gear ring 12 away from the arc plate 13. The cross-sectional shape of the side ring 16 is triangular. A blade 17 is fixed to one side of the side ring 16. The blade 17 is in an arc shape. The blades 17 are provided in multiple groups and are distributed in a circle on one side of the side ring 16. A fixing plate 18 is fixed to one side of the lifting frame 4. A guide plate 19 is fixed to the top of the fixing plate 18. The guide plate 19 is provided on one side of the side ring 16. The cross-sectional shape of the guide plate 19 is arc-shaped.

[0041] When the gear ring 12 rotates, it will drive the side ring 16 on one side to rotate together, and the multiple sets of blades 17 set on one side of the side ring 16 will also rotate with the side ring 16. Since the blades 17 are arc-shaped, when the multiple sets of arc-shaped blades 17 rotate together, a weak wind flow will be generated. By setting a fixing plate 18 on one side of the lifting frame 4, the guide plate 19 can be installed on one side of the side ring 16. By setting the guide plate 19, the direction of the wind flow can be guided. Since the center of the guide plate 19 is relatively narrow near the side ring 16, a narrow tube effect can be generated when the wind flow passes through, thereby increasing the wind force of the wind flow. Although the outer wall of the cable passing through the guide plate 19 has just been cleaned by the soft brush 15, there may be dirt and debris on the outer wall of the cable that has been scraped off but still remains. The dirt and debris remaining on the outer wall of the cable can be blown off by the weak wind flow to prevent the debris from remaining on the surface of the cable.

[0042] Reference Figure 7-9 The installation assembly includes a second gear 21, which is rotatably connected to the inner wall of the installation box 5. A first rack 20 is meshed on one side of the second gear 21. The top of the first rack 20 extends out of the installation box 5. A pressure plate 22 is fixedly connected to the bottom of the first rack 20. A first spring 23 is fixedly connected to the bottom of the inner wall of the installation box 5. A first hoop 24 is fixedly connected to the top of the inner wall of the installation box 5. The inner wall of the first hoop 24 is slidably connected to A second rack 25, the second rack 25 is meshed at the top of the second gear 21, a first block 26 is fixedly connected to one side of the second rack 25, one side of the first block 26 extends into a group of slots 3, a second hoop 27 is fixedly connected to the top of the inner wall of the installation box 5, a third rack 28 is slidably connected to the inner wall of the second hoop 27, the third rack 28 is meshed at the bottom of the second gear 21, a second block 29 is fixedly connected to one side of the third rack 28, one side of the second block 29 extends into another group of slots 3.

[0043] When it is necessary to fix the position of the installation box 5 and the lifting frame 4 on the fixing frame 1, the first rack 20 can be pressed first. When the first rack 20 moves downward, the pressure plate 22 will be pushed to squeeze the first spring 23, and the second gear 21 will be driven to rotate. When the second gear 21 rotates, the second rack 25 and the third rack 28 will be driven to move toward the center at the same time. By setting the first hoop 24 and the second hoop 27, the movement trajectory of the first rack 20 and the second rack 25 can be limited. When the second rack 25 and the third rack 28 move toward the center, the first block 26 and the second block 29 will be driven to move toward the center together, so that the first block 26 and the second block 29 are retracted for installation. The interior of the box 5 can be inserted into the installation slot 2. After the lifting frame 4 is moved to a suitable position, the first rack 20 can be released, and then the first spring 23 will reset upward after losing the thrust, and push the pressure plate 22 and the first rack 20 to reset upward. When the first rack 20 resets upward, it can drive the second gear 21 engaged on one side to rotate in the opposite direction, and when the second gear 21 rotates in the opposite direction, it will drive the second rack 25 and the third rack 28 to move outward, and push the first block 26 and the second block 29 to extend out of the installation box 5 until the first block 26 and the second block 29 are stuck in the slots 3 on both sides, so that the installation box 5 and the lifting frame 4 can be installed and fixed.

[0044] Reference Figure 12-13 The control component includes an L-shaped plate 30, the L-shaped plate 30 is fixedly connected to one side of the mounting groove 2, a second spring 31 is fixedly connected to one side of the L-shaped plate 30, the elastic force of the second spring 31 is smaller than the first spring 23, a sealing plate 32 is fixedly connected to one side of the second spring 31, the sealing plate 32 is arranged on one side of the air hole 34, a push piece 33 is fixedly connected to one side of the sealing plate 32, the L-shaped plate 30, the second spring 31, the sealing plate 32 and the push piece 33 are all arranged in two groups, and are symmetrically distributed on both sides of the air hole 34, one side of the first hoop 24 and the second hoop 27 are both provided with openings, one side of the second rack 25 is fixedly connected to a first push rod 38, one side of the third rack 28 is fixedly connected to a second push rod 39, one side of the mounting box 5 is provided with two groups of slide grooves, the first push rod 38 and the second push rod 39 are respectively slidably connected in the two groups of slide grooves, and the first push rod 38 and the second push rod 39 are respectively arranged on one side of the two groups of push pieces 33.

[0045] When the first block 26 and the second block 29 are retracted into the installation box 5, the first push rod 38 and the second push rod 39 will move toward the center, so that the first push rod 38 and the second push rod 39 can pass between the two groups of push plates 33. After the positions of the lifting frame 4 and the installation box 5 are fixed, the second rack 25 and the third rack 28 will be driven to move to both sides by loosening the first rack 20, and the first push rod 38 and the second push rod 39 will be driven to move to both sides. When the first push rod 38 and the second push rod 39 move to both sides, the two groups of push plates 33 and the sealing plate 32 will be pushed to move to both sides together, and the two groups of second springs 31 will be squeezed at the same time, so that the air hole 34 can be opened, so that the air duct 37 can pass through the air in the ventilation groove 36 to flow out, which can provide ventilation effect for the closed cable trench. At the air hole 34 where the lifting frame 4 does not need to be installed, the push plate 33 and the sealing plate 32 can be pushed by the two groups of second springs 31 to close the air hole 34 to prevent impurities from entering the ventilation groove 36.

[0046] Reference Figure 14-15 The ventilation assembly includes a bottom frame 41, which is fixedly connected to the bottom of the installation box 5. A bottom block 42 is fixedly connected to the bottom of the lifting frame 4. A threaded groove is provided on one side of the bottom block 42. The bottom block 42 is threadedly connected to a threaded rod 43 through the threaded groove. A guide groove 44 is provided at the bottom of the bottom frame 41. A guide block 45 is slidably connected to the inner wall of the guide groove 44. A connecting frame 46 is fixedly connected to the top of the guide block 45. The connecting frame 46 is slidably connected to the inner wall of the bottom frame 41. One end of the threaded rod 43 is rotatably connected to the bottom of the guide block 45. An inner plate 35 is fixedly connected to the inner wall of the air hole 34. The inner plate 35 and the connecting frame 46 are both square in shape. An inner cavity 40 is provided on the inner wall of the lifting frame 4. A heat dissipation hole is provided on the inner wall of the arc groove 6. A ventilation hole 34 is provided on the top of the lifting frame 4.

[0047] After the installation box 5 and the lifting frame 4 are installed on the fixing frame 1, the position of the bottom frame 41 will be aligned with the air hole 34, and then the threaded rod 43 can be rotated. When the threaded rod 43 rotates, the guide block 45 will be pushed to move to one side. Since the guide block 45 is slidably arranged inside the bottom frame 41, the movement trajectory of the guide block 45 can be limited. When the guide block 45 moves to one side, it will also drive the connecting frame 46 to slide inside the bottom frame 41 until the connecting frame 46 hits the inner plate 35 set on the inner wall of the air hole 34. The wind flow in the ventilation groove 36 can be transferred to the inner cavity 40 inside the lifting frame 4 through the connecting frame 46 and the bottom frame 41. After the wind flow flows into the inner cavity 40, it will flow to the bottom of the cable through the heat dissipation holes, which can provide a heat dissipation effect for the outer wall of the cable. By arranging the ventilation holes 34 at the top of the lifting frame 4, the wind flow can provide a ventilation effect around the cable to prevent the surrounding environment from being too high or humid.

[0048] Reference Figure 3 A long strip 47 is fixedly connected to the inner wall of the pulley 7 . The long strip 47 is in an arc shape. There are multiple groups of the long strips 47 , which are distributed in a circle on the inner wall of the pulley 7 .

[0049] By providing a plurality of rubber strips 47 on the inner wall of the pulley 7, when the cable moves, it is more convenient to drive the pulley 7 to rotate through the strips 47, thereby preventing the friction between the cable and the pulley 7 from being too small to drive the pulley 7 to rotate.

[0050] Working principle: In order to solve the problem that the outer wall of the cable is easy to be dirty when installing it, when the cable needs to be installed overhead, the fixing frame 1 can be installed in the cable trench first, and then the first rack 20 can be pressed. When the first rack 20 moves downward, it will push the pressure plate 22 to squeeze the first spring 23, and at the same time drive the second gear 21 to rotate. When the second gear 21 rotates, it will drive the second rack 25 and the third rack 28 to move toward the center at the same time. By setting the first hoop 24 and the second hoop 27, the movement trajectory of the first rack 20 and the second rack 25 can be limited. When the second rack 25 and the third rack 28 move toward the center, they will drive the first block 26 and the second block 29 to move toward the center together, so that the first block 26 and The second clamping block 29 is retracted into the installation box 5, so that the installation box 5 can be inserted into the installation slot 2. When the first clamping block 26 and the second clamping block 29 are retracted into the installation box 5, the first push rod 38 and the second push rod 39 will move toward the center, so that the first push rod 38 and the second push rod 39 can pass between the two sets of push plates 33. After the lifting frame 4 is moved to a suitable position, the first rack 20 can be released, and then the first spring 23 will reset upward after losing the thrust, and push the pressure plate 22 and the first rack 20 to reset upward. When the first rack 20 resets upward, it can drive the second gear 21 meshed on one side to rotate in the opposite direction, and when the second gear 21 rotates in the opposite direction, it will drive the second rack 25 and the third rack 28 to move outward and push the first clamping block 26. The first and second clamping blocks 29 extend out of the installation box 5 until the first and second clamping blocks 26 and 29 are clamped into the clamping grooves 3 on both sides, so that the installation box 5 and the lifting frame 4 can be installed and fixed. When the second rack 25 and the third rack 28 move to both sides, the first push rod 38 and the second push rod 39 will be driven to move to both sides. When the first push rod 38 and the second push rod 39 move to both sides, the two groups of push pieces 33 and the sealing plate 32 will be pushed to move to both sides together, and the two groups of second springs 31 will be squeezed at the same time, so that the air hole 34 can be opened, so that the air duct 37 can be transmitted to the ventilation slot 36 to flow out, which can provide ventilation effect for the closed cable trench. At the air hole 34 where the lifting frame 4 does not need to be installed, the push piece 33 and the sealing plate 32 can be pushed by the two groups of second springs 31. The sealing plate 32 seals the air hole 34 to prevent impurities from entering the ventilation slot 36. After the installation box 5 and the lifting frame 4 are installed on the fixing frame 1, the position of the bottom frame 41 is aligned with the air hole 34, and then the threaded rod 43 can be rotated. When the threaded rod 43 rotates, it pushes the guide block 45 to move to one side. Since the guide block 45 is slidably arranged inside the bottom frame 41, the movement trajectory of the guide block 45 can be limited. When the guide block 45 moves to one side, it will also drive the connecting frame 46 to slide inside the bottom frame 41 until the connecting frame 46 hits the inner plate 35 set on the inner wall of the air hole 34. The wind flow in the ventilation slot 36 can be transferred to the inner cavity 40 inside the lifting frame 4 through the connecting frame 46 and the bottom frame 41. After the wind flow flows into the inner cavity 40,The air will flow to the bottom of the cable through the heat dissipation holes, which can provide heat dissipation for the cable above the arc groove 6. By arranging the ventilation holes 34 at the top of the lifting frame 4, the air flow can provide ventilation for the surrounding of the cable to prevent the surrounding environment from being too high or humid.

[0051] After the lifting frame 4 is installed, the cable can be placed on the arc groove 6 on the lifting frame 4. After the cable is placed, the end of the cable can be pulled into the reserved hole until the end of the cable is pulled into the power room. The end of the cable can be installed at a specified position in the power room. When the cable moves to one side, since the cable is arranged at the top of the pulley 7, the pulley 7 is driven to rotate. When the pulley 7 rotates, the first bevel gear 8 on one side is driven to rotate. When the first bevel gear 8 rotates, it drives the meshing gear on one side. The second bevel gear 9 engaged with the lifting frame 4 rotates. When the second bevel gear 9 rotates, it will drive the rotating rod 10 on one side to rotate on the inner wall of the lifting frame 4, and the first gear 11 set at one end of the rotating rod 10 will also rotate with the rotating rod 10. When the first gear 11 rotates, it will drive the gear ring 12 engaged on one side to rotate. By setting an arc plate 13 on one side of the lifting frame 4, when the gear ring 12 rotates, the arc plate 13 can slide in the limiting groove 14 to limit the rotation of the gear ring 12. Since a soft brush is set inside the gear ring 12 15, so the gear ring 12 will drive the soft brush 15 to rotate when it rotates, and the dirt on the surface of the cable can be scraped off to prevent the dirt from being attached to the outer wall of the cable. When the gear ring 12 rotates, it will drive the side ring 16 on one side to rotate together, and the multiple sets of blades 17 set on one side of the side ring 16 will also rotate with the side ring 16. Since the shape of the blade 17 is an arc, when the multiple sets of arc-shaped blades 17 rotate together, a weak wind flow will be generated. By setting a fixing plate 18 on one side of the lifting frame 4, the guide The guide plate 19 is installed on one side of the side ring 16. By setting the guide plate 19, the direction of the wind flow can be guided. Since the center of the guide plate 19 and the area close to the side ring 16 are relatively narrow, a narrow tube effect can be generated when the wind flow passes through, thereby increasing the wind force of the wind flow. Although the outer wall of the cable passing through the guide plate 19 has just been cleaned by the soft brush 15, there may be dirt and debris on the outer wall of the cable that has been scraped off but still remains. The wind flow can blow off the dirt and debris remaining on the outer wall of the cable to prevent the debris from remaining on the surface of the cable.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
