WATER CANNON FOR WASHING INSULATOR USING HELICOPTER AND METHOD OF WASHING INSULATOR BY THE CANNON

摘要

An injector for insulator cleaning by using a helicopter and an insulator cleaning method using the injector are provided to be mounted on a helicopter, and to clean a polluted insulator by spraying high-pressure water with a pump, thereby easily cleaning the polluted insulator installed in a high position of a transmission tower. A rotational bar(10) comprises an axial hole(12), and combines upper ends of an 'A'-type supporting leg(20) and an 'I'-type reinforcing leg(30) in triangular pyramid type. An insertion bar(40) is inserted by two connection bands(42,46), and wherein an upper end of a rotational axis(60) inserted into the axial hole(12) is combined with the one-sided connection band(42) while a support(50) is combined with the other-sided connection band(46). A spray bar(70) is formed with a nozzle(72) on one end to be inserted into the insertion bar(40), and other end thereof is inserted into a handle bar where a connection hole(84) is formed.
