Description

Unmanned Cleaner {MANLESS CLEANING APPARATUS}

The present invention relates to an unmanned washing apparatus for automatically cleaning the home or business facilities, such as street lighting facilities, computer monitors, decorative glass, such as traffic monitoring cameras, street lights, tunnel lights.

In general, appliances and facilities having a transmissive panel, such as a plurality of glass panels, as well as a horizontal lighting facility installed outside, when smoke is left for a long time, soot, dust, etc. are attached, the light transmittance of the front panel is reduced. The street lighting facility includes a traffic monitoring camera, a street lamp, a lighting lamp installed inside the tunnel, a bulletin board with a glass panel, and the like. The household appliances and facilities include glass windows, TVs, monitors, and the like.

When the transmissivity of the traffic monitoring camera is reduced among the street lighting facilities, traffic confirmation, vehicle control, etc. become difficult. In addition, when the transmittance of the front panel of the street lamp or the tunnel lamp is reduced, smooth lighting may not be performed and traffic accidents and crime may occur.

In addition, in the case of street facilities such as bulletin boards, it is difficult not only to identify internal information but also to damage the aesthetics of the city.

In addition, household appliances and facilities cause aesthetic problems. As a result, the user needs to perform cleaning periodically, thereby increasing the administrative burden on the user.

Therefore, the cleaning operation must be performed periodically for street lighting facilities such as traffic surveillance cameras, streetlights, tunnel lights, bulletin boards, and the like, and appliances and facilities including a transparent surface for light transmission for home or business.

In accordance with this need, the Republic of Korea Utility Model Publication No. 362182 (Prior Art 1) installs a cleaning belt that blows in the wind on the outer surface of the tunnel lighting, so that the cleaning belt moves in accordance with the wind and cleans the lighting. It is starting.

In addition, the Republic of Korea Patent No. 893316 (Prior Art 2) has a tunnel light washer to wash the tunnel light by using a vertical maintenance boom having a brush head interlocked with the derrick boom freely swing operation and male rotation It is starting.
