Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment cleaning, and in particular refers to an insulation live cleaning device for electric power equipment. Background Art

[0002] Insulator flashover seriously threatens the safe and stable operation of the power grid. The main reason for insulator flashover is that the soluble substances attached to the surface of the insulation gradually dissolve in water under humid conditions, forming a conductive film on the surface of the insulation, which greatly reduces the insulation level of the insulator and causes strong discharge under the action of the electric field. Therefore, high-voltage insulators need to be cleaned regularly to ensure the cleanliness of the insulator surface and its insulation performance. In order to avoid losses caused by power outages during cleaning, the insulators need to be cleaned under power.

[0003] However, traditional live cleaning devices for power equipment are usually unable to adjust the spray speed and spray angle of the cleaning liquid, and use a single spray method to rinse the insulators with the cleaning liquid. The cleaning water consumption is high, and it is difficult to clean stubborn stains. There are great limitations in the cleaning process. Therefore, in order to be able to use different cleaning methods to clean the insulators during the cleaning process, improve the cleaning effect of the insulators and the utilization efficiency of the cleaning liquid, an insulation live cleaning device for power equipment is proposed. Summary of the invention

By arranging a cleaning component, the spray speed and flushing force can be increased when the nozzle is close to the insulator, and the spraying range of the insulation spray liquid can be expanded when the nozzle is far away from the insulator. The insulators are cleaned in a cycle in two flushing modes, thereby improving the cleaning effect of the insulator and the utilization efficiency of the cleaning liquid, and effectively solving the problem that the current live cleaning device of power equipment cannot adjust the spray speed and spray angle of the cleaning liquid, resulting in poor insulator cleaning effect.

[0040] Specific use and working principle: when live cleaning is performed on the insulator of the electronic equipment, the output end of the live cleaning liquid pump is connected to the liquid inlet 102, and the water flows through the liquid inlet 102, the driving gear 104, the air inlet pipe 206, the diverter box 205 and the connecting pipe 7 in sequence and enters the collecting box 311. Then, the water flows through the flow channel between the regulating block 314 and the nozzle 312, and is sprayed out from the speed increasing bucket 318, so as to blow off the dust on the insulator, and realize the live cleaning of the insulator;

[0041] During cleaning, the output end of the rotating motor 103 drives the driving gear 104 to rotate, so that the rotating assembly 2 rotates under the meshing action of the driving gear 104 and the driven gear 203, and then the cleaning assembly 3 at the bottom rotates, so that the nozzle 312 can perform rotational spraying around the circumference of the insulator;

[0042] While cleaning, the output end of the expansion motor 4 drives the rotating shaft 5 to rotate reciprocatingly, so that the rotating shaft 5 drives the expansion plate 301 to move relatively close to or away from it through the connecting rod 6, thereby adjusting the distance between the nozzle 312 and the insulator, and changing the flushing force of the cleaning liquid on the insulator; when the expansion plate 301 moves in the direction of approaching each other, that is, when the nozzle 312 moves in the direction of approaching the insulator, the connecting rod 6 drives the rotating shaft 304 to rotate, and the rotating shaft 304 drives the threaded rod 305 to rotate, so that the push plate 306 moves in the direction of approaching each other, so that the two groups of active pistons 303 approach each other, and the hydraulic oil in the hydraulic box 302 pushes the driven piston 308 to move, driving the lifting plate 309 to move downward, and the lifting plate 309 makes the adjustment plate 315 move in the direction of approaching the expansion plate 301 through the connecting rod 310. When the push plate 306 moves away from each other, the adjusting block 314 moves away from the speed increasing bucket 318, so that the cross-sectional area of ​​the flow channel formed between the adjusting head 319 and the speed increasing bucket 318 is increased, thereby increasing the spraying speed of the insulating cleaning liquid when it is sprayed from the nozzle 312, and the insulating cleaning liquid can be close to the insulator to rinse the insulator at a high flow rate, and the stubborn stains on the insulator are thoroughly cleaned; when the push plate 306 moves in a direction away from each other, the adjusting block 314 moves in a direction away from the speed increasing bucket 318, so that the cross-sectional area of ​​the flow channel formed between the adjusting head 319 and the speed increasing bucket 318 is increased, and the spraying range of the insulating spraying liquid is expanded, so that the cleaning liquid can rinse the insulator over a large area and quickly rinse the stains off the insulator; the two flushing methods are repeated to achieve live insulation cleaning of the insulator.
