Abstract

The invention discloses a detection robot for a suspension porcelain insulator string. The detection robot comprises a clamping mechanism, a lifting mechanism and a detecting mechanism, wherein the clamping mechanism comprises an upper clamping mechanism and a lower clamping mechanism, the lifting mechanism is arranged between the upper and the lower clamping mechanisms, and the detecting mechanism comprises a probe drive device which is arranged on the upper clamping mechanism and a detector triggering device which is arranged on the lower clamping mechanism; the upper and lower clamping mechanisms are respectively provided with a flexible insulation paw which is matched with the outer edge of an insulator shed; the clamping mechanism, the lifting mechanism and the detecting mechanism are connected with the controller respectively through a circuit. The robot is designed by adequately utilizing appearance characteristics of the suspension porcelain insulator string, and the clamping paws are respectively made of rubber materials, so that abrasion on the insulator is small, and short-circuited insulators are fewer; the robot has good safety and a good protective value and the insulators are simple to string, the movement speed is stable, accuracy in detection is realized, and the robot system can move along the direction of the suspension porcelain insulator string and can be electrified for detection.

Description

technical field [0001] The invention relates to a mobile detection robot, in particular to a detection robot for hanging porcelain insulator strings. Background technique [0002] With the development of the power industry, a large number of insulators are used in power transmission and transformation systems. Insulators are insulation equipment used to connect wires and towers on overhead high-voltage transmission lines. The existence of degraded insulators directly threatens the safe operation of the power system. Therefore, The preventive detection of deteriorated insulators is of great significance to ensure the safe operation of high-voltage transmission lines. The traditional detection method of porcelain insulator strings is to manually climb the tower to work at high altitude. However, with the increase of voltage level, the length of insulator strings continues to increase, and the difficulty of manual detection operations is also increasing. A series of automatic ...

AI Technical Summary

Problems solved by technology

After analyzing the tester described in the patent, it is found that the ring bracket of the tester is more than three joints and fastened, which increases the difficulty of fitting and installing the insulator strings for high-altitude operators; this patent uses two upper and lower claws along the The same axis swings and clamps the upper and lower sides of the umbrella group of insulators. The contact surface of the claw positioning block is flat. From common sense, the outer surface of the insulator is curved, so the contact surface of the claw positioning block and the insulator is equivalent. In line contact, even if the positioning block is an elastic body, it cannot fit the outer surface of the insulator well, and the contact area is small, so that the clamping is not firm.
