[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] The embodiments of the present application provide a line monitoring and maintenance device to solve the problem in the prior art that after the monitoring equipment monitors the sag, it is difficult to adjust the sag and the efficiency is low, thereby improving the overall safety of the line after the line is installed for a long time.

[0038] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0039] In the prior art, after the monitoring equipment monitors the sag, the sag adjustment is difficult and inefficient, resulting in a decrease in the overall safety of the line after a long period of installation.

[0040] The research found that Figure 1-Figure 5 As shown, by arranging a corresponding adjustment structure on the erection tower and arranging two tractors on the cable, when in use, the two tractors, under the action of the adjustment structure, control the rotation of the first spool and the second spool to clamp the cable and move it in the direction away from or close to the mirror axis of the two adjacent erection towers, thereby facilitating the adjustment of the cable sag. This solves the problem in the prior art that after the monitoring equipment monitors the sag, the adjustment is difficult and inefficient, resulting in a reduction in the overall safety of the line after the line has been erected for a long time.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] Example:

[0043] like Figure 1-Figure 2 As shown, a line monitoring and maintenance device includes an adjustment structure 10 installed on a tower pole, and a cable 201 is installed between two adjacent tower poles;

[0044] The two ends of the cable 201 are respectively installed through corresponding adjustment structures 10 and erection tower poles;

[0045] The adjustment structure 10 includes a first support member 11 and a second support member 12, a first bobbin 112 and a second bobbin 121 are mounted between the first support member 11 and the second support member 12, and the first bobbin 112 and the second bobbin 121 are rotatably connected to the adjustment structure 10;

[0046] The two ends of the cable 201 are respectively wound on the corresponding second spools 121;

[0047] Two tractors 20 are mounted on the cable 201 , each of which is clamped on the cable 201 . The tractors 20 are connected to the corresponding first spool 112 via the traction rope 101 and are wound on the corresponding first spool 112 .

[0048] A monitoring structure is installed in the tractor 20 for monitoring the vertical distance between the lowest point of the cable 201 in the power transmission line and the horizontal ground.

[0049] By arranging a corresponding adjustment structure 10 on the erection tower and arranging two tractors 20 on the cable 201, when in use, the two tractors 20, under the action of the adjustment structure 10, control the rotation of the first spool 112 and the second spool 121 to clamp the cable 201 and move it in the direction away from or close to the mirror axis of the two adjacent erection towers, thereby facilitating the sag adjustment operation of the cable 201. This solves the problem in the prior art that after the monitoring equipment monitors the sag, the adjustment is difficult and inefficient, resulting in a reduction in the overall safety of the line after the line has been erected for a long time.

[0050] like Figure 2-Figure 3 As shown, the first spool 112 is located above the second spool 121. By arranging the first spool 112 above the second spool 121, the traction rope 101 is used to provide an upward traction force for the cable 201, which facilitates the retraction and extension of the cable 201 by the second spool 121, thereby facilitating the adjustment of the line sag.

[0051] like Figure 1-Figure 5 As shown, the first spool 112 is mounted between the first support member 11 and the second support member 12 and is rotatably connected to the adjustment structure 10 via the first rotating rod 111;

[0052] The second spool 121 is mounted between the first support member 11 and the second support member 12, and is rotatably connected to the adjustment structure 10 through a second rotating rod 123. The second rotating rod 123 is embedded in the second spool 121 and fixed to the second spool 121. A driving motor 122 is installed on the second support member 12. The second rotating rod 123 passes through the second support member 12 and is rotatably connected to the second support member 12. The driving motor 122 is installed on the second support member 12. A side of the second rotating rod 123 close to the driving motor 122 is fixedly connected to the output end of the driving motor 122. The driving motor 122 provides driving force for the second rotating rod 123.

[0053] A first gear 113 is fixedly sleeved on the first rotating rod 111 , and a second gear 124 is fixedly sleeved on the second spool 121 . The first gear 113 and the second gear 124 are meshed and connected.

[0054] By setting the first gear 113 and the second gear 124, and the first gear 113 is engaged with the second gear 124, therefore, when the driving motor 122 controls the second rotating rod 123 to rotate, and then drives the second spool 121 to rotate, since the second gear 124 is fixedly mounted on the second spool 121, the rotation of the second spool 121 drives the second gear 124 to rotate, and then drives the first gear 113 engaged with the second gear 124 to rotate, so that the second spool 121 can retract and release the cable 201 at the same time, and the first spool 112, under the action of the first gear 113 and the second gear 124, can synchronously realize the retraction and release operation of the traction rope 101, which can more conveniently realize that the traction rope 101 provides an upward traction force to the cable 201.

[0055] Specifically, in one embodiment, the circular surface diameter of the first spool 112 is the same as the circular surface diameter of the second spool 121, and the diameter of the first gear 113 is smaller than the diameter of the second gear 124. By controlling the circular surface diameter of the first spool 112 to be the same as the circular surface diameter of the second spool 121, and setting the diameter of the first gear 113 to be smaller than the diameter of the second gear 124, the rotation speed of the first spool 112 is faster than the rotation speed of the second spool 121, and the traction rope 101 fully provides upward traction to the cable 201, further improving the stability of the retraction and extension of the second spool 121 during the sag adjustment process.

[0056] like Figure 5 As shown, the first support member 11 is composed of an upper cover and a lower cover, the upper cover and the lower cover are detachably connected, a second mounting seat 103 is mounted on the lower cover, the upper cover is clamped on the lower cover, and the second spool 121 is rotatably connected to the second mounting seat 103 at one end thereof close to the second mounting seat 103;

[0057] The first mounting seat 102 is fixedly connected to the second support member 12 . One end of the second spool 121 close to the first mounting seat 102 is rotatably connected to the first mounting seat 102 . The driving motor 122 is mounted on the first mounting seat 102 .

[0058] By providing the first mounting seat 102 and the second mounting seat 103 , the stability of the second spool 121 during rotation can be further improved, and the first support member 11 is provided in a detachable form, which can facilitate the maintenance of the first gear 113 and the second gear 124 in the first support member 11 .

[0059] like Figure 1As shown, each of the tractors 20 is equipped with a displacement sensor;

[0060] In the initial state, the two tractors 20 are symmetrical about the mirror axis of the erection tower;

[0061] After the sag is adjusted, the lowest point of the cable 201 is located on the mirror axis of the erection tower.

[0062] During operation, the two adjustment structures 10 are respectively located on the erection towers on both sides, and the two ends of the cable 201 are respectively located on the corresponding second spools 121. The adjustment structure 10 is used to realize the erection of the cable 201, and the two tractors 20 are clamped on the cable 201. At this time, the two tractors 20 are symmetrical about the mirror axis. The monitoring structure set in the tractor 20 monitors the specific ground height of the lowest point of the cable 201 (the monitoring structure monitors the distance between the lowest point of the cable 201 and the ground, which is a prior art and will not be described in detail here);

[0063] When it is detected that the lowest point of the cable 201 is too low from the ground, the adjustment mechanism 10 needs to be activated to adjust the cable 201 in order to solve the problem that the sag of the cable 201 does not meet the assumed safety after the line has been erected for a long time, resulting in a reduction in the overall safety of the line.

[0064] When the sag is adjusted by using the adjustment structure 10, the first spools 112 on the two adjustment structures 10 are controlled to rotate to achieve the winding of the two traction ropes 101. Since the tractor 20 is clamped on the cable 201, an upward traction force is provided to each end of the cable 201. Then, the second spool 121 is controlled to rotate, and the cable 201 is wound by the second spool 121 to adjust the sag formed by the cable 201. During the adjustment process, the distance between the end of the tractor 20 close to the mirror axis of the erection tower and the mirror axis is measured in real time by the displacement sensor provided on the tractor 20. Since the two tractors 20 are symmetrical about the mirror axis in the initial state, the horizontal distance between the two tractors 20 and the mirror axis is kept the same, so that the two tractors 20 are always symmetrical about the mirror axis, which can achieve the lowest point of the cable 201 being on the mirror axis, thereby improving the aesthetics after the sag adjustment.

[0065] In actual application, in order to further improve the accuracy of sag adjustment, a reducer can be provided at one end of the second rotating rod 123 close to the driving motor 122 to facilitate fine adjustment of the first spool 112 and the second spool 121;

[0066] Specifically, manual control can be used to adjust the overall operation of the structure 10. When manual control is used, the drive motor 122 is not provided on the side of the second rotating rod 123 close to the second support member 12. The end of the second rotating rod 123 close to the second support member 12 is provided with a labor-saving structure and a limiting structure, so that after the cable 201 is manually controlled to be reeled, the limiting structure fixes the reeled second spool 121.

[0067] The numerical control can also be used to control the adjustment structure 10. The numerical control and the drive motor 122 transmit signals to adjust the drive motor 122 according to actual needs.

[0068] In summary, compared with the existing technology, the present invention has the following beneficial effects:

[0069] 1. By arranging a corresponding adjustment structure 10 on the erection tower and arranging two tractors 20 on the cable 201, when in use, the two tractors 20, under the action of the adjustment structure 10, control the rotation of the first spool 112 and the second spool 121 to clamp the cable 201 and move it in the direction away from or close to the mirror axis of the two adjacent erection towers, thereby facilitating the sag adjustment operation of the cable 201. This solves the problem in the prior art that after the monitoring equipment monitors the sag, the adjustment is difficult and inefficient, resulting in a reduction in the overall safety of the line after a long period of installation.

[0070] 2. By arranging the first spool 112 above the second spool 121, the traction rope 101 is used to provide an upward traction force for the cable 201, which facilitates the retraction and release of the cable 201 by the second spool 121, thereby facilitating the adjustment of the line sag.

[0071] 3. By setting the first gear 113 and the second gear 124, and the first gear 113 is engaged with the second gear 124, therefore, when the driving motor 122 controls the second rotating rod 123 to rotate, and then drives the second spool 121 to rotate, since the second gear 124 is fixedly sleeved on the second spool 121, the rotation of the second spool 121 drives the second gear 124 to rotate, and then drives the first gear 113 engaged with the second gear 124 to rotate, so that the second spool 121 can retract and release the cable 201 at the same time, and the first spool 112, under the action of the first gear 113 and the second gear 124, can synchronously realize the retraction and release operation of the traction rope 101, which can more conveniently realize that the traction rope 101 provides an upward traction force to the cable 201.
