Abstract

The invention discloses a high-voltage line inspection robot which comprises an integral supporting frame. The integral supporting frame is provided with a main controller and a power supply. The upper end surface of the integral supporting frame is provided with an image acquiring mechanism and two sliding mechanisms. The upper end of each sliding mechanism is provided with a driving mechanism, and the lower end is provided with a clamping mechanism. A high-voltage line channel is formed between the clamping mechanism and the driving mechanism. When bestriding of an obstacle is required, the driving mechanism and the clamping mechanism can be driven to rotate through the sliding mechanism, thereby reducing control difficulty in bestriding the obstacle. Through the clamping mechanism and the driving mechanism, a clamping force of the high-voltage line inspection robot to a high-voltage power transmission line can be effectively controlled, and furthermore the high-voltage line inspection robot can climb on a certain slope. Furthermore when obstacle bestriding is required, one end, which is separated from the high-voltage power transmission line, of the driving wheel of the device may reduce by a certain height, and the driving wheel can be re-attached with the high-voltage power transmission line through an elevating mechanism.

[0065] When the robot moves on the high-voltage transmission line, the image acquisition mechanism 18 can be used to determine the obstacles on the high-voltage transmission line, and then different obstacle-surmounting schemes can be formulated according to different obstacles, so that the robot can autonomously cross the high-voltage transmission line. different obstacles.
[0066] Taking spanning the spacer bar as an example, the use method of the present invention is specifically described,
[0067] 1. Place the robot on the high-voltage transmission line, and determine the distance between the two sliding mechanisms 8 and the auxiliary sliding mechanism 156 in the direction of the overall support frame 1 according to the size of the fixing hardware on the high-voltage transmission line, such as spacers and anti-vibration hammers.
[0068] 2. Control the movement of the drive motor in the drive mechanism 5 through the main controller, thereby driving the robot to move forward.
[0069] 3. The distance between the robot and the spacer bar is determined according to the infrared ranging sensor of the first lifting mechanism 3 or the camera 182 of the image acquisition mechanism 18. When the appropriate distance is reached, the robot stops moving and approaches the sliding mechanism 8 of the spacer bar. The first lifting mechanism 3 and the second lifting mechanism 6 drive the clamping mechanism 2 and the driving mechanism 5 to move away from the wire body.
[0070] 4. When the clamping mechanism 2 and the driving mechanism 5 reach the proper position driven by the first lifting mechanism 3 and the second lifting mechanism 6, the large gear 87 of the sliding mechanism 8 is rotated by a certain angle under the driving of the pinion 90, so that the driving Mechanism 5 and clamping mechanism 2 can avoid spacer bars.
[0071] 5. Control the motion of the drive motor in the drive mechanism 5 away from the spacer bar, so that the robot continues to move forward, so that the sliding mechanism 8 close to the spacer bar passes the spacer bar.
[0072] 6. The large gear 87 returns to the initial position driven by the pinion 90 .
[0073]7. The clamping mechanism 2 and the driving mechanism 5 return to the initial positions under the driving of the first lifting mechanism 3 and the second lifting mechanism 6 .
[0074] 8. Then the first lifting mechanism 3 and the second lifting mechanism 6 of the two sliding mechanisms 8 move at the same time, driving the control box 17 of the robot to move upward as a whole, so that the support wheel 151 of the intermediate support mechanism 15 is separated from the wire body.
[0075] 9. The large gear 87 of the auxiliary sliding mechanism 156 is rotated by a certain angle under the driving of the pinion 90, so that the intermediate support mechanism 15 goes over the spacer bar.
[0076] 10. After the intermediate support mechanism 15 passes over the spacer bar, the large gear 87 of the auxiliary sliding mechanism 156 is driven by the pinion gear 90 to rotate to the initial position.
[0077] 11. The first lifting mechanism 3 and the second lifting mechanism 6 of the two sliding mechanisms 8 move at the same time, driving the control box 17 of the robot to return to the initial position, thus completing the obstacle crossing of the intermediate support mechanism 15 .
[0078] 12. The obstacle surmounting method of the sliding mechanism 8 far away from the spacer is the same as the obstacle surmounting method of the sliding mechanism 8 close to the spacer, which will not be repeated here.
[0079] When the robot needs to climb a slope, the inclination angle of the robot is determined according to the gyro sensor carried by the robot itself, and then the moving distance of the first lifting mechanism 3 is determined, and the distance between the clamping mechanism 2 and the driving mechanism 5 located in the front is increased. Positive pressure increases the positive pressure between the rear clamping mechanism 2 and the driving mechanism 5, and the driving wheel 53 of the driving mechanism 5 can complete the climbing motion of the robot without slipping.
[0080] The downhill movement of the robot is similar to the uphill movement, and the uniform movement of the robot is also realized by adjusting the positive pressure between the clamping mechanism 2 and the driving mechanism 5 .
