<p>A wiper device for a dome for cleaning a spherical clear dome window (2) installed at the front of a housing, comprising a semi-circular arc-shaped wiper arm (3) having both wiper end parts formed to be rotatable about near the center axis of the spherical clear dome window (2) and discharge holes (17) formed on the inside of the wiper arm (3) along the curved surface of the clear dome window (2) and discharging a high-pressure fluid in the state of being separated from the dome window by a specified distance. The wiper device is characterized by comprising a driving means reciprocatingly moving the wiper arm (3) by filling the high-pressure fluid from the end part of the wiper arm (3). As a result, the wiper device can clean the spherical clear dome window at the front of the housing storing TV cameras and video cameras installed in the building without damaging the window.</p> |
