Description
Technical field
The utility model belongs to the ultra-high-tension power transmission line field, relates to a kind of Pneumatic cleaning arm of electrified cleaning device for cleaning defilements of direct current converter station.
Background technology
Current conversion station alternating current-direct current equipment contamination comparing result shows that DC equipment contamination situation is more serious than alternating current equipment contamination situation, and the salt secret agreement of the contamination of D.C. isolation is for exchanging close about 2～6 times of insulation alite.Filth can not only make insulating surface produce pollution flashover, causes device damage thereby can also cause to insulate to be damaged in the equipment.
Live cleaning at post insulator of DC converter station, some researchs have been carried out both at home and abroad, at present main live cleaning (washing) method has dried cleaning, air-blowing and water flushing etc., adopt in the actual production more be the water backwashing manner, but the general AC Substation that only is used for 220kV and following electric pressure of water backwashing manner more.These live cleanings (washing) method exists some shortcomings that are difficult to overcome as: specification requirement height,, poor stability big based on manually-operated, labour intensity, operation easier height, cleaning weak effect etc.This shows, be used at present charged cleaning (sweeping) technology of direct current electric transmission and transformation insulator arrangement and device both at home and abroad cleaning weak effect, labour intensity are big because technical reason also exists, poor stability, the high deficiency of operation easier.Because the Electrostatic Absorption effect is seriously many than ac high-voltage equipment contamination, the cleaning difficulty is bigger for HVDC Equipment.For ± the 500kV post insulator of DC converter station is densely distributed, and every insulator reaches 7m～8m, constitutes by reaching 30～40 insulator full skirts, and the method for artificial charged cleaning wastes time and energy and not only has certain danger, and cleaning performance is relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of Pneumatic cleaning arm of electrified cleaning device for cleaning defilements of direct current converter station, utilize compressed air-driven cleaning arm and hairbrush to carry out various cleaning actions, simultaneously cleaning fluid is sprayed onto predetermined cleaning position, to do two kinds of sweeper mode of cleaning and cleaning fluid cleaning and match, greatly improve the cleaning effect.Existing cleaning technology or clearing apparatus cleaning weak effect, inefficient problem have been solved, can guarantee to realize good cleaning effect, can significantly improve the dielectric level of distribution line, can stop the generation of pollution flashover accident fully substantially, and help carrying out livewire work.
The technical solution of the utility model is: a kind of Pneumatic cleaning arm of electrified cleaning device for cleaning defilements of direct current converter station, by fixed arm, oscillating oil cylinder, transmission arm, fixed head, swing span, gas motor and wheel brush are formed, it is characterized in that: fixed arm and fixed head all are fixed on the insulating support of clearing apparatus, fixed head and swing span are 2/3 circular insulating support, five groups of draw-in grooves have been installed in the fixed head below, swing span is installed in the fixed head below by draw-in groove, swing span can slide in draw-in groove, oscillating oil cylinder is connected on the swing span by transmission arm, on swing span, be bottom, equilateral triangle position three gas motors have been installed at a distance of 1/3 annulus, a wheel brush is all fixed in every gas motor bottom, and the shower nozzle of insulation cleaning fluid has been installed by the wheel side of brushing.
Operation principle of the present utility model is: oscillating oil cylinder orders about down compressed-air actuated, can control swing span carries out certain angle below fixed head swing by transmission arm, be installed on the three groups of gas motors driven wheel brush rotation under compressed-air actuated driving under the swing span simultaneously, be installed on the wheel side of brushing insulation cleaning fluid shower nozzle simultaneously and spray cleaning fluid, carry out washing and cleaning operation to the cleaning object.
The utlity model has following beneficial effect:
1, cleans left side pendulum and the right swing work that action frames are encircled cleaning and swing span by three, guaranteed that the wheel brush can cover the cleaning object surface fully, guarantees that support insulator can be cleaned comprehensively;
2, the nylon yarn length of the wheel brush length of stretching out greater than the insulator cluster parachute can guarantee that insulator can fully be swept into;
3, dried sweeper mode of the utility model or cleaning fluid sweeper mode combine, and have improved sweeping efficiency.
