Description

technical field [0001] The invention belongs to the technical field of maintenance equipment for power transmission and transformation lines, and in particular relates to a water-repellent spraying device for insulators for detecting electrification in the air of power transmission lines. Background technique [0002] Insulators are used to support and fix busbars and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the ground. Due to the special shed structure of the insulator and long-term exposure to the air, solids and liquids suspended in the air Or gas particles deposit on the surface of the insulator to form a pollution layer, which affects the insulation performance of the insulator and causes pollution flashover. [0003] Composite insulators are vulcanized silicone rubber coatings on the outer surface of the insulator layer. The excellent pollution flashover resistance of composite insulators comes...

Problems solved by technology

[0004] In actual use, due to pollution, humidity, discharge and other factors, the hydrophobic performance of the silicone rubber coating on the surface of electrical equipment in operation will decrease or even be lost, and the decrease in hydrophobicity will even directly affect the resistance of power transmission and transformation equipment. Pollution flashover performance, thus threatening the safe operation of the system, requires operators to regularly test the hydrophobicity of the silicone rubber coating of the insulator string. The existing detection method is that the operator climbs up and inspects each insulator on the insulator string The process of water spraying detection one by one is as follows: firstly, the water spraying device needs to be fixed on the insulator string, after one insulator point is detected, and then the water spraying device is manually dismantled and installed to the next detection point; this method has a large workload. , The disadvantage of heavy operation, and for insulator strings of different diameters, it is necessary to select the corresponding water spray fixtures, which is inconvenient to carry. In addition, the safety of working at heights cannot be guaranteed.

The drone is equipped with a wireless remote control device, a water spray device, and an image acquisition and transmission device. The water spray device includes Water tank, water pump and nozzle, the water pump is connected with the water tank, and the water pump is connected with the nozzle through the water spray conduit; the image collection and transmission device includes a camera and an image transmitter, and the image transmitter is connected with the camera; the wireless remote control device includes a wireless remote control receiver, The wireless communication module, the nozzle remote control mechanism, the camera remote control mechanism and the water pump starter, the wireless remote control receiver are respectively connected with the nozzle remote control mechanism, the camera remote control mechanism and the water pump starter; the nozzle remote control mechanism is connected with the nozzle, the camera remote control mechanism is connected with the camera Connection, the water pump starter is connected with the water pump; the disadvantage of this structure is that when the UAV is in the process of landing, the center of gravity will be unstable, which will cause the problem of tilting the fuselage, which will cause certain damage to the propeller of the UAV. damage

The disadvantage of this structure is that when in use, the stabilizing device during the landing process is not designed, nor is the mechanism for stabilizing the center of gravity of the device designed, and there is a problem of unstable hovering during landing and flight
