[0051] Among them, by arranging a claw 12 at the bottom of the mounting frame 11, the inner side of the claw 12 can be clamped with the counterweight 13. When the device is used in windy conditions, the assembly of the counterweight 13 lowers the center of gravity of the device, thereby improving the stability of the device during operation, thereby reducing the risk of the device swinging due to external environmental factors during use;
[0052] When the anti-separation component 14 is in use, the screw rod 144 moves upward along the surface of the support frame 141 by turning the knob 142. At this time, the positioning plate 145 drives the ball sleeve 146 to move upward together until the ball 147 in the ball sleeve 146 contacts the surface of the high-voltage line, and the knob 142 is stopped from being turned. In this way, the high-voltage line and the driving wheel 17 can be pressed tightly by the ball 147 to prevent the driving wheel 17 from slipping with the high-voltage line when rotating. The ball 147 can slide freely in the ball sleeve 146, so that it can play a boosting role when the guide device 1 moves along the surface of the high-voltage line.
[0053] During this process, the U-shaped plate 143 moves upward together with the knob 142 and the screw rod 144, and slides along the inner wall of the fixing frame 15. At this time, the air in the fixing frame 15 is squeezed and the locking block 18 is pushed to the outside of the fixing frame 15. At this time, the U-shaped plate 143 and the locking block 18 are close to each other and the distance between them becomes smaller, so as to prevent the high-voltage wire from falling off from the gap between the U-shaped plate 143 and the locking block 18 during the operation of the equipment.
[0054] During the detection process, the rubber ring 10 at the bottom of the fixing rod 19 slides along the surface of the high-voltage wire, and can clean the impurities attached to the surface of the high-voltage wire that the driving wheel 17 does not contact, thereby preventing the driving wheel 17 from getting stuck or contaminated with impurities when rolling along the surface of the high-voltage wire;
[0055] When the fixing device 3 is in use, the staff places the two semi-ring guide rails 31 on the outside of the high-voltage line, and then quickly connects the two semi-ring guide rails 31 together by setting the locking assembly 34, so that the displacement assembly 32 can rotate 360 degrees along the two semi-ring guide rails 31, so that the detection probe 4 can detect the high-voltage line without blind spots, expanding the detection range of the detection probe 4, and the fixing device 3 can be connected to the wheel frame 5 by setting the support plate 33, so that the guide wheel 6 can drive the fixing device 3 to move along the surface of the high-voltage line;
[0056] When the displacement assembly 32 is in use, the motor 322 located outside the housing 321 drives the driving wheel 323 to rotate, and the driving wheel 323 can roll along the outer side of the semi-ring guide rail 31. At the same time, under the tension of the tension spring 324, the displacement block 325 always keeps the tendency to slide upward along the inner wall of the housing 321, so that the driven wheel 326 can always contact the inner side of the semi-ring guide rail 31, thereby preventing the displacement assembly 32 from detaching from the surface of the semi-ring guide rail 31 during the movement.
[0057] When the displacement assembly 32 is moving, the scraper component 327 can scrape off the impurities on the surface of the semi-circular guide rail 31. The scraper 273 is fixed by setting the arc rod 271, so that the scraper 273 can slide along the surface of the semi-circular guide rail 31 during movement, and can scrape off impurities such as bird droppings that fall on the surface of the semi-circular guide rail 31 to ensure the normal operation of the displacement assembly 32. At the same time, the arc rod 271 is auxiliary supported by setting the elastic rod 272 and the connecting rod 274. The arc rod 271 and the elastic rod 272 are staggered, which increases the structural strength of the arc rod 271 and prevents the arc rod 271 from being deformed too much due to the squeezing effect of the scraper 273.
[0058] In the process of connecting the two semi-ring guide rails 31 together, the semi-ring guide rails 31 on both sides are placed symmetrically, and the two semi-cylinders 343 are rotated 90 degrees at the same time, so that the two semi-cylinders 343 can clamp the semi-circular blocks 342 on both sides at the same time. At this time, under the connection of the mounting block 341, the two semi-ring guide rails 31 can be connected together, and the operation is simple;
[0059] During this process, under the restriction of the limit sleeve 344, the compression spring 346 always pushes the sliding rod 345 to the side away from the annular block 347, so that the sliding rod 345 can be stuck in the groove opened on the surface of the semi-circular block 342 when the semi-cylinder 343 rotates ninety degrees, thereby limiting the position of the semi-cylinder 343, which can prevent the semi-cylinder 343 from deflecting relative to the semi-circular block 342 when the device is in use, causing the semi-circular guide rails 31 on both sides to separate.
