SYSTEM FOR CLEANING BUILDINGS

The present invention relates to a method and system for cleaning building.

Cleaning buildings with nano cleaner can be managed, directed and controlled in a control office by a computer through a system according to an embodiment of the invention.

The control office can be in any place and has no distance limitation with the building. Most systems of cleaning the buildings are operated manually by human operators using their hand. They are in boxes hanging in the sky that is most often very dangerous. In the present system, the cleaning zone is limited due to the manual system of cleaning so the cleaning process is highly time-consuming.

Furthermore, due to the risks of falling from height, the boxes in which operators should stand are limited in terms of weight resulting in the limitation of cleaning materials carried by operators.

This method and system seeks to reduce or at least ameliorate at least one of the problems associated with the prior art.

According to a first aspect of the present invention there is provided a system as claimed in claim 1.

According to a further aspect of the present invention there is provided a system for cleaning the surface of a building, the system comprising: a cleaning head set for supplying cleaning materials to the surface of the building; and the system further comprising means for displacing the cleaning head set, the means being configured to allow the cleaning head set to follow a surface contour of the building surface.

Preferably, the means for displacing the cleaning head set is configured to allow the cleaning head set to move in two mutually orthogonal directions.

Preferably, the cleaning head set is provided with nozzles, the nozzles being configured to move generally perpendicular to the surface plane of the building, such that the nozzles can be adapted to the surface contour of the building.

Preferably, the means for displacing the cleaning head set includes; a substantially horizontal support axis for supporting the cleaning head set; means for adjusting the vertical displacement of the support axis; and means for allowing reciprocal displacement of the cleaning head along the support axis.

Preferably, the means for adjusting the vertical displacement of the support axis comprises a pulley and winch system.

Preferably, the means for adjusting the vertical displacement of the support axis comprises vertical lifting units attached to the support axis.

Preferably, the support axis is formed to follow a curved profile.

Preferably, the system further comprises a computer for controlling the means for displacing the cleaning head set.

Preferably, the computer controls the supply of cleaning materials to the cleaning head set.

Preferably, the computer is provided with a wireless connection for controlling the cleaning head set.

Eliminating such inconveniences, this method no longer requires the use of operators or suspended boxes enabling a single operator to control and manage the system from a control office.

Furthermore, since cleaning material is carried through pipes from tanks placed on a car, no limitation is faced and the whole process becomes less time-consuming.

In current methods, cleaning the projection and indented surfaces is limited as it is carried out manually. However, the present method, utilising heads which are capable of getting small and big, experiences no limitation.

The purpose of the system shown in Figure 1 is cleaning the outer surface of a building by the nozzle set of head 5. The computer 20 has a wireless connection with the winches 2, 15, 36, 44 through control office 19 and manages and controls the displacement of the steel wires 9, 28 in the direction of the Y coordinate.

The computer 20 manages and controls motor 8 wirelessly from control office 19. Motor 8 displaces the head set 7 that lies on axis 6 in direction of X coordinate.

Nozzles 5 will have displacement in direction of a Z coordinate with building surfaces through close distance or tangent to the building (flat, convex, and concave surface).

After cleaning each surface, motor 8 displaces the head set 7 that is placed on axis 6.

Nozzles 5 are comprised of compressed air, magnetizing system (electric magnet) and steam and nano cleaner that can be measured with regard to the surfaces of the buildings and can be adjusted (injection timing, range adjustment and pressure control) for the period of cleaning time and increasing or decreasing the amount of cleaning. By the pipes set 11 , the compressed air and steam and nano cleaner are transferred and directed to the head set 7 and then to nozzles 5 from tanks 13 on the car 14.

The head set 7 is provided with means for displacing the cleaning head in two mutually orthogonal directions to follow the surface contour of the building 1. The head set 7 is supported on a substantially horizontal support axis 6. The support axis may be a horizontal beam or other means for supporting the head set 7. The head set 7 comprises a displacing motor 8 for displacing and moving the head set 7 along the support axis 6, which is an axis generally horizontal to the ground 18 and parallel to an external face of the building 1. The support axis 6 is connected at either end to respective steel wire joints 42, 12 using respective nuts and bolts 17, 41 to respective generally vertical steel wires 9, 38. The steel wires 9, 48 are each connected at their upper ends around respective upper pulleys 39, 10 to respective upper winches 2, 36. The steel wires 9, 38 are connected at their lower ends i.e. the ends nearest the ground 18 around lower pulleys 16, 43 to lower winches 44, 15. Each of the lower pulleys 43, 16 is connected to the ground via respective lower pulley support bases 21 , 45. The upper pulleys 39, 10 are connected to the building via respective upper pulley support bases 37, 3.

A computer 20 is provided which has a wireless connection with winches 2, 15, 36, 44 to control the movement of the steel wires 9, 38 around the pulleys, to cause a vertical displacement of the steel wire joints 12, 42 and the support axis 6 connected thereto.

The computer 20 is located in a management, direction, and control office 19 in the present embodiment away from the building 1 in order to operate the system. The computer 20 also manages and controls the motor 8 of the cleaning head set 7 to control movement of the head set 7 along the X-axis or horizontal axis 6, i.e. an axis

horizontal and parallel to the plane of the outer side of the building. The motor allows for reciprocating movement of the head set 7 along the support axis 6.

The nozzles 5 of the head set 7 may be displaced or moved in a direction perpendicular to the surface plane of the building 1. The nozzles 5 can therefore be placed in close proximity to the building or even at a tangent to the building depending on the contour of the surface of the building e.g. a flat, convex or concave surface. The nozzles are therefore may be adapted, i.e. the displacement of each nozzle may be adjusted so that each nozzle is a similar distance from the surface of the building. In the embodiment shown the head set comprises four nozzles. The nozzles are used to supply cleaning materials to the surface of the building.

After an area of the surface of the building 1 has been cleaned by the nozzles 5, the motor 8 in the head set 7 displaces their head set 7 along the support axis in a direction generally horizontal and parallel to the outer surface of the building so that a adjacent or different area of the surface of the building may then be cleaned. The head set 7 may be moved to various locations of the surface of the building by displacing the head set along the support axis 6 and/or adjusting the vertical height of the head set 7.

In contrast to the first embodiment, the head set 7 is supported by a horizontal support axis 6, which axis 6 is connected at end thereof by means of joints 22 and 47 to

respective vertical support axes 23 and 46. The vertical support axes could for example be vertical posts. The joints 22 and 47 are provided with respective electric motors 34 in order to allow the joints 22 and 47 to move reciprocally in a vertical direction on the support axes 23 and 46 to allow the head set 7 to be reciprocally displaced in a vertical direction. The motor drives a gearbox to produce the vertical movement.

As in the first and second embodiments, the head set 7 may be reciprocally displaced using the motor 8 along the support axis 6. The lifters 28 and 49 allow the support axis 6 to be displaced in a vertical direction. These could for example be telescopic lifting units or hydraulic lifting units. In the embodiment shown, the lifters 28 and 49 are provided with a motor set for raising and lowering the head set 7. The lifters are provided on a portable unit provided with wheels 35 and 52. The portable unit allows the system to be easily displaced and located adjacent the building 1.

The purpose of the system shown in Figure 3 is in accordance with Figure 1. The axis 6 is jointed to lifter 28 and 49 by means of joints 27 and 51 and displacement occurs in the direction of Y coordinate by getting small and big lifters 49 and 28. The lifters are placed on motor set and lifter components 29 and 50 and the whole set of 29 and 50 are placed on the portable set and lifter wheel 35 and 52. Being portable, it is easily possible to displace the whole system near the building.
