Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a cleaning material for a wall surface cleaner of a high-rise building.

``Prior Art'' Conventionally, the cleaning material in a wall cleaning device for a high-rise building is equipped with a rotating brush to wash the wall surface with water, and the cleaning waste water is wiped off with a rubber plate. The walls of modern buildings are made of mirror-treated heat-reflecting glass surfaces, aluminum sash surfaces, etc., so cleaning with water using a rotating brush can easily damage the walls, and wiping cleaning waste water with a rubber plate can cause the same waste water to enter the joints. There was a defect in which wastewater flowed into the recesses and flowed out onto the surface from the joints and recesses after wiping, staining the surface.

"Problems to be Solved by the Invention" The present invention aims to prevent damage to building walls and staining caused by cleaning wastewater.

``Means for Solving Problems'' The present invention provides a water supply device, a rotating shaft, and its driving device in a cage suspended vertically along a wall surface, and a plurality of flexible sponge pieces are attached to the outer periphery of the rotating shaft. A cleaning material for a building cleaner, in which the rotating shaft and the sponge piece are disposed at a position where the end part is supported and the tip of the sponge piece comes into pressure contact with a wall surface by the centrifugal force caused by the rotation of the rotating shaft. be done.

"Operation" Therefore, when the cage 2 is lowered along the wall surface 1 and the rotating shaft 4 is rotated by the drive device, a plurality of flexible sponge pieces 6
The distal end thereof is rotated by centrifugal force so that it is in pressure contact with the wall surface, and the accumulated dirt on the surface of the wall surface 1 and in the joints and recesses can be washed with water.

After cleaning, when the water supply is stopped and the rotating shaft 4 and the sponge piece 6 are rotated, the water adhering to the sponge piece will be scattered and dehydrated due to centrifugal force.In this state, if the tip of the sponge piece 6 is pressed against the wall l in the same manner as described above, The tip can enter not only the surface of the wall but also the joints and recesses to wipe away cleaning waste water on the surface, inside the joints, or inside the recesses.

``Example'' Using a winding machine installed on the roof, wire rope is used to wrap the building wall 1.
A wall cleaning cage 2 is suspended so as to be able to rise and fall freely along the wall. This cage 2 is provided with a water supply device f3 consisting of a water tank 7, a pump 8, a water supply nozzle 9, etc.1, and a horizontal rotation shaft 4 is provided on the wall surface l side over the width of the cage 2, and 4 drive devices 5 (electric motors) are provided. The outer periphery of the rotating shaft 4 is shown in FIGS. 7 and 8. Figures 9 and 10
As shown in the figure, the proximal ends of the plurality of flexible sponge pieces 6 can be supported directly, or indirectly as shown in FIGS. 3 and 4. The sponge piece 6F1 may be a non-water-absorbing aggregate of closed cells as shown in FIG. 6, or a water-absorbing aggregate of open cells as shown in FIG. 12. The sponge piece 6 may be in the form of a string or band as shown in FIGS. 3 to 5 and 10, or may be in the form of a sheet as shown in FIGS. 7 to 9, but it is flexible. When at rest, (b) the rotating shaft 4 hangs down as shown in FIGS. 2 and 10.

(B) When the rotating shaft 4 rotates (B), the centrifugal force causes the 11N
, opens as shown in FIGS. 3, 4, and 7 to 9, and its tip comes into pressure contact with the wall 1 as shown by the imaginary line in FIGS. 1 and 2. With this, it is possible to press not only the surface but also the inside of tile joints and other recesses. The position of the rolling shaft 4, where the tip of the sponge piece 6 presses against the wall l due to centrifugal force, is on the horizontal guide 10 as shown in FIG. 2 even when it is fixed to the cage 2 as shown in FIG. There is no problem even if it is in the forward sliding position by sliding it back and forth toward the wall surface 1. Drive device i! The five rotating shafts 4 can be switched between high speed and low speed rotation, and the sponge pieces 6 can be dehydrated by high speed rotation. In addition, there is a Monoke power transmission cable indicated by 11 in the drawing, 12 washing sewage introduction plates, and 13 in FIG. 2 a wall engagement guide for the Ifi cage 2, which are not shown in FIG. It also has a flexible mesh inside the 14-piece sponge.

``Effects'' Since the present invention is constructed as described above, the tip of the flexible sponge piece 6 is pressed against the wall surface of the building by centrifugal force and is slid in close contact with water for washing. It is suitable for cleaning a movable and uneven wall surface 1, and not only can the surface be cleaned safely without the risk of damaging the surface, but also the water adhering to the sponge piece 6 can be dehydrated by centrifugal force, and in that state, the wall surface 1 can be cleaned with many unevenness. By thoroughly wiping the surface of the wall l and the recesses, it is possible to prevent staining caused by residual cleaning wastewater flowing down into the recesses.
