Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a wall surface cleaning device which does not scatter polluted water to the outside when cleaning an outer wall surface at a high position such as a building and window glass. .

[Prior Art] Conventionally, as this kind of technology, there has been known one that employs a seal plate to prevent polluted cleaning water from dropping along a window glass or the like (for example, Japanese Utility Model Publication No. 60-10516). reference).

Further, there is known one provided with a jet nozzle, a rotating brush, a squeegee, a main jet nozzle and an auxiliary jet nozzle (for example, see Japanese Utility Model Publication No. 55-207).

[Problems to be Solved by the Invention] In the former of those described in the prior art, the effect is exerted only on a surface having a smooth surface such as a window, and when a rough surface such as an outer wall is sealed with a sealing plate, contamination occurs. Since water falls from the gap between the seal plate and the recess, it cannot prevent the outflow of polluted water to the outside, and because the seal plate and squeegee rub against the uneven surface, the wear of these becomes severe and the sealing effect is reduced. However, there was a problem that the outflow of polluted water could not be completely prevented.

Further, in the latter, the jet nozzle and the rotating brush are provided, but they are separately configured, and when cleaning the rough surface such as the outer wall as in the former, the squeegee rubs the uneven surface, so that the wear of these is eliminated. It became intense and the sealing effect could not be expected.

Furthermore, both of them lacked versatility because of their complicated structure, large size, and high price.

The present invention has been made in view of the above problems of the above-mentioned conventional technology, has a simple structure, is small in size, can be manufactured at low cost, has general versatility, and can sufficiently prevent the wash water from flowing out. The purpose is to provide a wall cleaning device.

[Means for Solving the Problems] A wall surface cleaning device according to the present invention is a wall surface cleaning device that includes a cleaning rotating brush and a cleaning water jet nozzle and that moves up and down along a surface to be processed by the operation of an endless winch. At the center of the upper surface of the recovery tank with an open upper surface, a box having a width equivalent to that of the recovery tank housing the rotation mechanism is fixed, and a plurality of rotating brushes interlocked with the rotation mechanism are provided on the front surface of the box. A rear end of a shield hood having an open front face is fixed to each of the box body and the front edge of the upper surface of the recovery tank to cover the plurality of rotary brushes from the rear, and the outer peripheral edge of the front end of the shield hood is further provided. Is provided on the outer peripheral surface of the shielding hood, the air duct having an air ejection nozzle for ejecting air from the inside inward.

[Operation] According to the present invention configured as described above, when the endless winch is actuated to raise and lower the wall to clean the wall, the cleaning water ejected from the cleaning water ejecting nozzle works with the rotating brush to clean the wall and then contaminate it. It becomes water and flows down the wall, or is scattered to the outside by the centrifugal force of the rotating brush, but the air is jetted inward from the air jet nozzle provided on the outer peripheral surface of the tip of the shielding hood that covers the rotating brush. The polluted water is sprayed to the inside of the hood, which is made up of a box, a shielded hood, and a collection tank, to prevent outside scattering.

Further, the air and polluted water pushed into the hood flow into the collection tank through the discharge port on the front of the collection tank upper surface, where the polluted water is separated and collected in the collection tank, and the air is exhausted at the rear of the collection tank upper surface. Is exhausted to the atmosphere.
