The inspection device is not only safer, but also more labor-saving and much easier to operate than drones. It solves the problem that the current inspection method of inspectors climbing on the overhead cables is not only unsafe but also physically demanding. Moreover, although the surface of the overhead cables can be inspected through the camera on the drone inspection device, the drone inspection device is difficult to operate.

[0046] A cover 43 is installed behind the auxiliary pipe 39, and the cover 43 is threadedly connected to the receiving box 38; a transmission motor 44 is fixedly installed on one side of the outer wall of the support ring 3, and the output end of the transmission motor 44 is coaxially connected to a driving rod 45, and the outer wall of the driving rod 45 is threadedly connected to a transmission gear 46, and the outer wall of the transmission gear 46 is meshedly connected to a linkage gear ring 47, and the inner wall of the linkage gear ring 47 is fixedly connected to the outer wall of the rotating ring 28. The auxiliary pipe 39 is fixedly connected to the receiving box 38, and the inner walls of the injection pipe 37 and the receiving box 38 are both set as smooth surfaces.

[0047] The method of using the inspection device for overhead power lines of the present invention is as follows:

[0048] First, when the present invention is used for inspection of overhead power cables, the threaded cover 25 is rotated forwardly, the threaded cover 25 and the inlet pipe 24 are threadedly separated, the top opening of the storage box 23 is opened, and the marking paint is poured into the inlet pipe 24, and the inlet pipe 24 enters the storage box 23, and the threaded cover 25 is reversed, and the threaded cover 25 and the inlet pipe 24 are threadedly locked to close the storage box 23. At the same time, the cover body 43 and the receiving box 38 are threadedly separated, and the feed port of the receiving box 38 is opened. After separation, the marking paint can be poured into the feed port of the receiving box 38, and the connection between the cover body 43 and the receiving box 38 is reversed and blocked. The battery 19 supplies power, and the background computer remotely starts the wireless controller 20, and the wireless controller 20 starts the two reduction motors 15, and the casing 1 supports the support block 16, and the support block 16 supports the reduction motor 15, and the reduction motor 15 drives the transmission rod 14 to transmit, and the transmission rod 14 rotates inside the casing 1, and the transmission roller 13 realizes a rotation operation above the outer wall of the overhead cable 12, and the casing 1 moves at the same time.

[0049] At the same time, after the overhead cable 12 contacts the two limit rollers 17, the two limit rollers 17 can rotate inside the casing 1, the limit rollers 17 carry the rotating shaft 18 to rotate, the rotating shaft 18 rotates inside the casing 1, and the casing 1 can move along the overhead cable 12 as a whole, the casing 1 drives the bracket 2 to move, the bracket 2 drives the support ring 3 to move, the support ring 3 drives the multiple detection cameras 4 to move, and the images detected by the multiple detection cameras 4 are transmitted to the background computer through the wireless controller 20, so that the personnel can check and see whether there are missing or damaged problems on the outside of the overhead cable 12. When the detection camera 4 collects and detects the damaged part on the overhead cable 12, the reduction motor 15 is turned off through the wireless controller 20.

[0050] Secondly, when the present invention performs horizontal interval marking, the wireless controller 20 starts the drive motor 11 to drive the screw 6 to rotate, and the screw 6 rotates inside the support frame 5. Since the two threads on the outer wall of the screw 6 are opposite and symmetrically arranged, the screw 6 carries two threaded sleeves 7 to approach each other under the action of the thread transmission force, one of the threaded sleeves 7 drives the two linkage plates 8 to move left, and the other threaded sleeve 7 drives the other two linkage plates 8 to move right, and the linkage plate 8 drives the arc tube 9 to approach the overhead cable 12, and multiple arc tubes 9 all approach the overhead cable 12, and multiple arc spray holes 10 all approach and fit the overhead cable 12. After approaching, the drive motor 11 is turned off by the wireless controller 20, so that multiple arc spray holes 10 can approach and fit the horizontal marking position of the outer wall of the overhead cable 12.

[0051] Then, when the present invention is pressurized, the boosting pump 26 is started to allow the pressurized air to enter the boosting pipe 27, and is poured into the storage box 23 through the boosting pipe 27. The marking paint inside the storage box 23 is pressurized and transported to the inside of the two hoses 22. The two hoses 22 are respectively branched into two connecting pipes 21, and the connecting pipes 21 are branched into two arc tubes 9. The arc tubes 9 spray the marking paint onto the outer wall of the overhead cable 12 through the arc spray holes 10. The two arc spray holes 10 in the front can spray out a circular paint marking line, and the two arc spray holes 10 in the rear can spray out another circular paint marking line, which can mark the interval position of the horizontal inspection problem on the outer wall of the overhead cable 12.

[0052] Finally, when the present invention performs vertical interval marking, when the detection camera 4 detects the defective position of the overhead cable 12, the identification barcode 34 data on the detection camera 4 that detects the problem is input into the wireless controller 20, and the problem is that there is a missing or damaged problem on the outside of the overhead cable 12. The wireless controller 20 can start the transmission motor 44, the transmission motor 44 drives the drive rod 45 to rotate, the drive rod 45 carries the transmission gear 46 to rotate, the transmission gear 46 engages and carries the linkage gear ring 47 to rotate, the linkage gear ring 47 drives the rotating ring 28 to rotate, and the rotating ring 28 rotates inside the support ring 3. At the same time, the rotating ring 28 realizes the limited rotation operation on the inner wall of the limit ring 29. The rotating ring 28 drives the rotating rod 30 to rotate, the rotating rod 30 drives the shunt pipe 31 to rotate, the shunt pipe 31 drives the two nozzles 35 to rotate, the two nozzles 35 can realize vertical rotation and movement along the outside of the overhead cable 12, and the shunt pipe 31 drives the socket block 32 to rotate.

[0053] The socket block 32 drives the barcode sensor 33 to rotate, and the barcode sensor 33 can realize rotational movement on multiple identification barcodes 34. When the barcode value sensed by the barcode sensor 33 on the identification barcode 34 is the same as the problem barcode value set on the wireless controller 20, the transmission motor 44 is turned off through the wireless controller 20, and the two nozzles 35 can rotate to the vertical interval position for collecting the problem. The electric valve 42 is opened through the wireless controller 20 to start the booster air pump 40. The booster air pump 40 enables the booster branch pipe 41 to boost the receiving box 38. The marking paint inside the receiving box 38 can enter the filling pipe 37. When the receiving box 38 is tilted, the marking paint will be deposited at the mouth of the auxiliary pipe 39. In this way, the auxiliary pipe 39 can also transport the marking paint into the filling pipe 37 in a tilted state, and enter the valve 36 through the filling pipe 37. After opening the valve 36, the marking paint is poured into the shunt pipe 31, and then enters the two nozzles 35 from the shunt pipe 31. The two nozzles 35 can realize the spray marking operation on the vertical problem area outside the overhead cable 12.

[0054] The vertical positions of the inspection problems on the outside of the overhead cable 12 can be marked at intervals. Later, maintenance personnel can check the horizontal interval marking paint position on the overhead cable 12, quickly move to that position, and then find the vertical interval marking position, so that they can quickly and accurately find the problem part of the overhead cable 12, perform maintenance operations on the problem part of the overhead cable 12, and use a cleaning agent to spray off the paint after the maintenance is completed, which greatly improves the efficiency of inspection and maintenance processing.
