APPARATUS FOR ROTATING A JET NOZZLE OF WATER JET SYSTEM

摘要

A device for rotating a jet nozzle of a water jet system is provided to prevent the leakage of water by forming a water screen in a simple structure and to combine a high-pressure water supply hose stably. In a device for rotating a jet nozzle of a water jet system, a rotary driving unit(10) is composed of: a housing(11); a motor(12) installed on the upside of the housing; a driving gear combined with the motor in the housing; and a speed reducing gear disposed in the housing and engaged with the driving gear. A rotary shaft(20) is vertically installed in the center of the speed reducing gear, rotatably combined with the housing, and equipped with a vertical water feed passage. A hose combining unit(30) is mounted on the upside of the housing correspondently to the upper end of the rotary shaft and vertically joined with a supply hose feeding the high-pressure water, on the upper surface. A watertightness inducing unit is assembled to the hose combining unit to move the high-pressure water fed through the supply hose, to the water feed passage without leakage. A nozzle combining unit(50) is installed at the lower end of the rotary shaft to support the lower end of the watertightness inducing unit and equipped with the jet nozzle at the lower side.
