Embodiment 1

[0036] The method for testing the hydrophobicity of vulcanized silicone rubber coatings on transmission lines, the steps are as follows:

[0037] S1: Adopt a suspended detection device with a traveling mechanism 14, use a multi-rotor aircraft to lift it to the line 7 to be tested, and control it to hang on the line 7 through the remote control of the operator;

[0038] S2: After hanging on the line 7, the multi-rotor aircraft stops working to save energy consumption, and drives the device to walk on the line through the traveling mechanism 14;

[0039] S3: Walk directly on the line 7 through this device, and collect and analyze the actual condition of the line through the front image acquisition module 8 set on it. If condensation occurs on the line 7, use the drying mechanism 9 on the line 7 dry to ensure the accuracy of detection after the water spray mechanism 10 sprays water;

[0040] S4: after drying, image acquisition is carried out by the middle image acquisition modul...

Embodiment 3

[0057] It differs from the second embodiment in that: the automatic telescopic rod 23 is an electric telescopic rod.

[0058] In this embodiment, a center-of-gravity adjustment module is provided at the bottom of the frame to adjust the center of gravity of the trolley, so as to avoid the instability of the center of gravity from affecting the work of the trolley; The position of the block can be used to adjust the center of gravity; the automatic telescopic rod adopts an electric telescopic rod, which has the advantages of small size and easy control.

Embodiment 4

[0060] The difference between it and Embodiment 3 is that: the upper part of the water tank 5 is provided with a water inlet, and the water inlet is connected with a water pipe 16, and the lower end of the water pipe 16 is connected with a quick joint 17, and the quick joint 17 is used to connect to the water tank on the ground. A water pump to fill the tank with water.

[0061] In this embodiment, a water inlet is provided on the upper part of the water tank, and the water inlet is connected with a water pipe, and the lower end of the water pipe is connected to the water pump on the ground through a quick joint, so that the water tank can be filled through the water pipe as required, thereby increasing the online operation of the device Time; The water-repellent agent that adopts in this embodiment pressurizes the storage tank by an air pump, then the water-repellent agent in the material storage tank is delivered to the spray nozzle through the paint pipe of its bottom, and a...

Abstract

The invention discloses a hydrophobicity detection method of a power transmission line vulcanized silicone rubber coating. The method comprises the following steps: adopting a suspension type detection device with a walk mechanism, lifting the suspension type detection device to a to-be-detected line by use of a multi-rotor type aircraft, and remotely controlling the suspension type detection device through an operator so as to suspend the detection device on the line; the device can directly walk on the line and acquire and analyze the actual condition of the line through a front image acquisition module arranged on the device, if the condensation occurs on the line, a drying mechanism arranged on the detection device is used for drying the line so as to guarantee the accuracy of the water spray detection; through the mutual synergistic effect of a lifting mechanism and other mechanisms, the detection device can be easily hung on the high-altitude line, and continuously works on the line through the walk mechanism, so that the real data of the line hydrophobicity can be more comprehensively acquired. The method disclosed by the invention is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of power transformation operation and maintenance equipment, in particular to a method for detecting the hydrophobicity of a vulcanized silicone rubber coating of a power transmission line. Background technique [0002] Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, the insulator will not have a significant effect, which will damage the service life and operating life of the entire line. Composite insulators are more and more widely used in power lines due to their good antifouling properties. Composite insulators are external insulation devices that need long-term operation, and the design requires that their service life is gen...
