Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0038] like Figure 1 As shown, the present application provides an overhead power transmission line detection and obstacle removal device, including an equipment box 1, on which a walking component 2 is arranged, and the walking component 2 is used to walk on the power transmission line, specifically:

[0039] The walking assembly 2 includes a plurality of support rods 23 fixedly mounted on the equipment box 1, a mounting platform (not shown) is fixedly mounted on the top of the support rods 23, and a mounting frame 21 is fixedly mounted on the mounting platform, and two sets of first rollers 22 are rotatably mounted on the mounting frame 21;

[0040] At the same time, a servo motor (not shown in the figure) is fixedly installed inside the device box 1, and a screw rod 251 is fixedly installed at the output end of the servo motor. The screw rod 251 is exposed from the device box 1, and the screw rod 251 is rotatably installed on the device box 1, and then driven by the servo motor, the screw rod 251 can be driven to rotate;

[0041] A sleeve 24 is threadedly mounted on the screw rod 251, and a guide rod 25 is provided through the sleeve 24. The guide rod 25 is installed between the bottom of the mounting platform and the equipment box 1, so that when the screw rod 251 rotates, the sleeve 24 is synchronously driven to move in the axial direction of the screw rod 251, and under the action of the guide rod 25, the movement direction of the sleeve 24 is limited;

[0042] At the same time, two groups of support plates 27 are hinged on the equipment box 1, and connecting plates 26 are hinged on the two groups of support plates 27. The two groups of connecting plates 26 are hinged on the sliding sleeve 24, and then when the sliding sleeve 24 moves, the connecting plates 26 are synchronously driven to move, and then the two groups of support plates 27 are driven to move closer to or away from each other. In the initial state, the two groups of support plates 27 are away from each other, which is defined as the initial position;

[0043] like Figure 1-Figure 2 As shown, a fixing block 28 is fixedly installed at one end of the two groups of support plates 27 away from the connecting plate 26, a slide groove is provided inside the fixing block 28, a slider 29 is slidably provided inside the slide groove, and a straight plate 331 is fixedly installed on the slider 29, a support frame 33 is fixedly installed on the straight plate 331, and a round rod (not marked in the figure) is rotatably installed on the support frame 33, a second roller 34 is fixedly sleeved on the round rod, and the height of the second roller 34 is higher than the height of the first roller 22 at this time;

[0044] One end of the round rod is connected to a driving device, which may be an electric motor or a hydraulic motor, and the driving device is mounted on the support frame 33 so that the first roller 22 is driven to rotate through the round rod under the drive of the driving device;

[0045] At the same time, a boss is provided on the top of the fixed block 28, on which a stepping motor 3 is fixedly installed, and a gear 31 is fixedly installed at the output end of the stepping motor 3, and a rack 32 is fixedly installed on the slider 29, and the rack 32 is meshed and connected with the gear 31, so that under the drive of the stepping motor 3, the slider 29 is driven to move through the cooperation of the gear 31 and the rack 32, thereby driving the straight plate 331 and the support frame 33 to move, and then driving the second roller 34 to move;

[0046] It should be noted that the slide grooves on the two sets of fixed blocks 28 are arranged relative to each other, and then under the drive of the two sets of stepper motors 3, the two sets of sliders 29 can move relative to each other, that is, move closer to or away from each other;

[0047] Continue to refer Figure 1 A rotating part 41 is provided at the top of one of the support frames 33, and a motor is provided inside the rotating part 41. The output end of the motor is connected to the camera 4, and then driven by the motor, the camera 4 is driven to rotate 360° in the horizontal direction, so that the staff can observe the surrounding situation;

[0048] To sum up, when going online, the drone transports it to the transmission line, starts the stepper motor 3, and through the cooperation of the gear 31 and the rack 32, the two groups of second rollers 34 move away from each other. The drone lifts the first roller 22 from the bottom of the transmission line until the first roller 22 fits with the lower surface of the transmission line. At this time, the second gear 31 is located above both sides of the transmission line. Then the stepper motor 3 drives the two groups of second rollers 34 to reset so that they are located above the transmission line. The servo motor is started to drive the sleeve 24 to move, thereby driving the two groups of connecting plates 26 to move, and then driving the two groups of support plates 27 to move away from each other, and driving the second rollers 34 to move away from each other to adjust the distance between the second rollers 34 and the first rollers 22 until the second rollers 34 fit with the upper surface of the transmission line. Then the driving device is started to drive the round rod to rotate, thereby driving the second rollers 34 to rotate, so that it can walk on the transmission line and observe the surrounding environment through the camera 4;

[0049] At the same time, an obstacle removal component 5 is arranged on the equipment box 1, and the obstacle removal component 5 is used for clearing foreign objects from the power transmission line;

[0050] like Figure 1 and Figure 4-Figure 5 As shown, the obstacle removal assembly 5 includes a first mechanical arm 51 fixedly mounted on one side of the equipment box 1, a sheath 52 is provided on the first mechanical arm 51, and a cylinder (not shown in the figure) is provided inside the sheath 52, a push rod 57 is fixedly mounted on the output end of the cylinder, and a cutter 55 is hinged at one end of the push rod 57;

[0051] Continue to refer Figure 5 A fixing plate 53 is fixedly mounted on the sheath 52. The fixing plate 53 is located on one side of the cutter 55. The fixing plate 53 has a fixed blade 531 adapted to the cutter 55, and a rotating shaft 551 is fixedly mounted on the fixing plate 53. The cutter 55 is rotatably mounted on the fixing plate 53. Then, driven by the cylinder, the push rod 57 can be extended and retracted, thereby driving the cutter 55 to rotate in the axial direction of the rotating shaft 551, so as to drive the cutter 55 to approach or move away from the fixed blade 531, and when approaching the fixed blade 531, the cutter 55 can cross the fixed blade 531 to shear foreign matter;

[0052] Continue to refer Figure 4A fixing clamp 56 is fixedly installed on the other side of the fixing plate 53, and a serrated clamp 54 is fixedly installed on one side of the cutter 55, so that when the cutter 55 approaches the fixed edge 531, the serrated clamp 54 is synchronously driven to approach the fixing clamp 56, and the width of the serrated clamp 54 is smaller than that of the cutter 55, so as to avoid interference with the cutter 55 and the fixed edge 531 when the cutter 55 and the fixed edge 531 are staggered for shearing, and when the shearing action is completed, the serrated clamp 54 and the fixing clamp 56 are abutted, so that foreign matter can be clamped;

[0053] A second mechanical arm 58 is fixedly mounted on the other side of the equipment box 1, and a mechanical gripper 59 is fixedly mounted on the second mechanical arm 58. The mechanical gripper 59 is a prior art, such as the gripper structure mentioned in the patent with publication number CN111300469A. The specific structure and principle are not described in detail here.

[0054] In summary, when foreign objects are observed on the transmission line through the camera 4, the second mechanical arm 58 is started to drive the mechanical gripper 59 to clamp and clean the foreign objects. When there are linear objects wrapped around the transmission line, the second mechanical arm 58 is started to drive the cutter 55 to move to the linear object so that the linear object is between the cutter 55 and the fixed blade 531. Then, the cylinder is started to drive the push rod 57 to contract, thereby driving the cutter 55 on the rotating shaft 551 to approach the fixed blade 531 until the cutter 55 and the fixed blade 531 cross each other, so as to cut the linear object. Then, the second mechanical arm 58 drives the mechanical gripper 59 to clean it.

[0055] It should be noted that, in the present application, two sets of mechanical arms can cooperate to clean foreign objects on the transmission line, or they can clean foreign objects on multiple sets of transmission lines separately, that is, when cleaning multiple sets of lines, the sawtooth clamp 54 is moved to the foreign object, and the shearing action is repeated, so that the sawtooth clamp 54 and the fixed clamp 56 clamp the foreign object, thereby cleaning it;

[0056] At the same time, a scraper assembly 6 is provided on both sets of support frames 33, and the scraper assembly 6 is used to scrape away the condensed sludge on the surface of the transmission line;

[0057] like Figure 3 and Figure 6 As shown, the scraper assembly 6 includes a pad 62 fixedly mounted on one of the support frames 33, a drive motor is fixedly mounted on the pad 62, and a protective shell 61 is provided outside the drive motor to protect the drive motor;

[0058] An elliptical wheel 66 is fixedly mounted on the output end of the driving motor. The elliptical wheel 66 is located at the bottom of the pad 62, and two sets of connecting handles 63 are rotatably mounted on the bottom of the pad 62. The two sets of connecting handles 63 are arranged alternately, and one end of the two sets of connecting handles 63 is located on both sides of the elliptical wheel 66.

[0059] It should be noted that the two ends of the elliptical wheel 66 have convex surfaces, so under the drive of the motor, the elliptical wheel 66 can be driven to rotate, so that the convex surfaces at the two ends of the elliptical wheel 66 abut against the two sets of connecting handles 63 to squeeze the two sets of connecting handles 63, thereby making the two sets of connecting handles 63 move away from each other, and as the elliptical wheel 66 continues to rotate, the two sets of convex surfaces separate from the two sets of connecting handles 63, so that the two sets of connecting handles 63 can move closer to each other;

[0060] A mounting block 64 is fixedly mounted on the other end of the two sets of connecting handles 63, and a semicircular scraper 65 is fixedly mounted on the mounting block 64, so that when the two sets of connecting plates 26 approach or move away from each other, the two sets of semicircular scrapers 65 are synchronously driven to approach or move away from each other, and when approaching, a circle is formed, and the circle is adapted to the power transmission line. Then, when the self-propelled assembly moves, the semicircular scraper 65 is used to scrape away the condensed dirt on the power transmission line to prevent the dirt from interfering with the movement of the second roller 34;

[0061] At the same time, when the two sets of semicircular scrapers 65 are away from each other, the UAV will not interfere with the walking assembly 2 when it is transported to the transmission line;

[0062] To summarize, before the UAV transports the walking component 2 to the transmission line, the drive motor is started to drive the elliptical wheel 66 to rotate, so that the two sets of convex surfaces of the elliptical wheel 66 are against the two sets of connecting handles 63, thereby driving the two sets of connecting handles 63 away from each other, and then driving the two sets of mounting blocks 64 away from each other, so as to synchronously drive the two sets of semicircular scrapers 65 away from each other, so as to avoid interference with the process of the UAV transporting the walking component 2 to the transmission line. When the walking component 2 is transported to the transmission line, the drive motor is started again, so that the two sets of convex surfaces of the elliptical wheel 66 are separated from the two sets of connecting handles 63, thereby driving the two sets of semicircular scrapers 65 to approach each other and wrap the outer surface of the transmission line, and the walking component 2 is started, and the semicircular scrapers 65 are synchronously driven to move on the transmission line to scrape off the condensed sludge on the circumferential surface of the transmission line, so as to avoid interference with the movement of the walking component 2.

[0063] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
