A brush assembly 4 attached to the top portion of the supporting frame 3. The brush assembly 4 is composed of a rotatable brush unit 41 formed in one piece, or several sub-brush units. A water baffle 42 is hinged, together with the brush unit 41, to the supporting frame 3, with its center of gravity set in a lower position. In doing so, the water baffle 42 may always be located at the position right behind the brush unit 41 without turning together with the supporting frame 3 thereby preventing the used water from spraying at the apparatus. In addition, a guide plate 421 is formed at the lower edge of the water baffle 42 so that used water may be gathered with a hose to directly drain away into a nearby sewage system. A row of nozzles 43 for supplying detergent by spraying is provided on the water baffle 42 at the position below the brush unit 41, the nozzles 43 are connected to a detergent container 432 (refer to Fig. 4) mounted on the working platform 1 with a hose 431. On the other hand, a row of nozzles 44 for supplying clean water 44 is provided on the water baffle 42 at the position above the brush unit 41, the nozzle 44 are connected to a water supply source (not shown) with a hose 441. With this structure, the work of cleansing building a wall can be performed orderly and effectively mixing clean water with detergent first, and then rubbing the wall surface with the brush unit 41. Meanwhile, the brush unit 41 is driven by a motor 45 mounted on the supporting o• frame 3. In addition, in order to produce a relevant pressure against the wall surface, the tilted angle of the supporting frame 3 with respect to the wall surface can be adjusted when cleansing the wall with the brush unit 41.
A blower unit 5 including a blower body 51 is mounted on the working platform 1, the blower body 51 has a wind output exit 52 connected to the blower body 51 with a hose 53. The wind exit 52 is disposed above the brush assembly 4 when cleaning the wall, and the wind exit 52 is stretchable and retractable for conveniently performing the work. With this construction, the wall surface 8 can be quickly dried after cleansing. Also, a heat accumulator 54 may be installed in the blower body 51 or at the wind output exit 52 so as to supply hot wind for performing instant drying of said wall surface.
A control unit 6 is mounted on the working platform 1 for control of the lift unit 2, the supporting frame 3, the brush assembly 4, and the blower unit 5 to work relevantly. A control board 61 is extended out of the control unit 6 therefrom both for automatic and manual operation.
Several detector units 7 are scatteringly equipped on the blower unit 5, on the wind output terminal 52, or on the brush assembly 4 for detecting the distance between the cleansing apparatus and the wall surface 8 thereby automatically adjusting the brush assembly 4 to maintain the most suitable inclined angle with the wall surface 8.
As shown in Fig. 3, the cleansing apparatus of the present invention can be mounted on the ground 9 with the castors 32 of the supporting frame 3 and rolled along the ground 9 together with the working platform 1 thereon.
As shown in Fig. 4, the steps of operating the cleansing apparatus of the present invention are; First, lift the working platform 1 slightly off the ground 9, and turn the brush assembly 4 to a relevant working angle by adjusting the supporting frame 3.
Next, operate the control board 61 to preset operation procedures of each component described above; Then, lifting the working platform 1 to the topmost position of the building with lifts 21, and aim the detectors 7 at the wall surface 8. Bring down gradually the working platform 1 from its highest point and at this moment the control unit 6 will automatically assign the brush assembly 4 to start working by driving the brush unit 41 to rotate with the motor and rubbing the wall surface 8 with water mixed with detergent supplied by the nozzles 43. Finally, spray the wall surface 8 with clean water supplied by the nozzles 44, and blow the wall surface 8 with hot wind by the blower unit 5 if quick drying is required.
After the work is completed, bring the working platform 1 down to the ground 9 and restore the supporting frame 3 to its normal 10 upright state with the control unit 6, and then assure all components restore the stand by state.
S* As mentioned above, the information of distance between the cleansing apparatus and the wall surface 8 is transmitted to the control unit 6 with a signal outputted from the sensor 7 equipped at 15 the wind output terminal 52 or at other places so as to adjust the tilted angle of the brush assembly 4 to a relevant value thereby upgrading the cleansing quality. The used water mixed with **detergent and dust on the wall surface 8 is partially flowing down along the wall surface 8 however, most of it would have scattered here and there by rotating of the brush assembly 4 if there had not been for installation of the water baffle 42. The water baffle 42 gathers most of used water and conducts it into the sewage system with the hose by the guide plate 421 so as to avoid environmental contamination. Other than automatic control, the cleansing work can be carried out manually by working crew standing on the platform 1 and to operate the control board 61 step by step.
Fig. 5 shows the brush assembly 4 in another embodiment, in the embodiment, an auxiliary rotatable brush 46 is attached to each side of the brush unit 41. The auxiliary brush 46 is used to clean corners, recessed portions and other similar locations where the ordinary figured brush unit 41 can not reach to clean. In the case the auxiliary brush 46 is not required, it can be detached while-the vacancy thereof can be alternatively plugged in a soft protective filler not shown so as to protect the cleansing apparatus from being inclined owing to attack of strong wind.
As shown in Fig. 6, the steel wire 22 of the lift 21 is drawn up and fixed at a anchor base 81 fixed on the topmost portion of the S• wall surface 8. When both lifts 21 are started, the working platform 1 is moved up and down along the wall surface 8 by pulling force of the steel wire 22.
