Description

 Hanging wall washing device  

The invention relates to an automatic cleaning technology for a building exterior wall (including glass), in particular to a hanging wall washing device.

Since most of the external walls of buildings are erected on the surface, the cleaning work of the external walls of buildings has been manually carried out on the hanging platform for vertical lifting and brushing. However, the construction environment for such artificial cleaning is very dangerous and easy. Caused a safety accident. At present, there has been a market for automatic wall washers, which can improve the dangers caused by the above-mentioned artificial construction.

The technology of the automatic wall washer is known, for example, in Taiwan Patent Publications M327752, M407717, M442887, M509691, etc., and the wall washer with the brush wheel attached from the top floor of the building is disclosed by the rope, so that the wall washing machine can be vertical Lift the way to clean the exterior wall. However, since the wall is washed by the brush wheel in the body to contact and clean the dirt on the outer wall, the wall washer that is suspended by the rope must be in addition to the lifting control of the rope between the outer walls of the high floor. In addition to the external factors such as wind, it must also withstand the reaction force of the brush surface of the contour surface of the wall such as vertical, concave and convex, so that the brush wheel can fully roll contact during the wall washing process. Whether the external wall, that is, the stability of the wall surface is sufficient, has become an important technical issue for the external wall cleaning effect.

In order to overcome this problem, the above patent teaches that an exhaust fan is also provided in the wall washer, and in the process of washing the wall, the exhaust fan can generate a back pressure (or negative pressure) environment in the chamber of the body configuration brush wheel, so that the brush The wheel can achieve better wall stability during the wall washing process. However, the actual results of the operators show that the airflow between the high-rise walls is extremely unstable due to the uncertain factors such as wind and other weather factors. If the wall washer relies only on the back pressure generated by the above-mentioned exhaust fans to stabilize the wall washer, or upgrade The stability of the brush wheel wall washing is not enough.

To this end, Taiwan Patent No. M528801 teaches the erection of rails between the outer walls to guide the lifting movement of the wall washer during the wall washing process. However, the practice of setting up the wall-lifting lifting rail on the outer wall is extremely costly to assemble and disassemble, and it also affects the appearance of the building during the cleaning process, which is not an excellent improvement solution.

In addition, since the brush wheel disposed in the body of the wall washer is generally made of bristles, the bristles can also be replaced by sponges, and when the bristles or sponges roll over the wall for a long time, some of them will cause deformation or hair loss. Such defects affect the cleaning effect of the wall washing. Therefore, the brush wheel has become a consumable that must be replaced regularly in the wall washer; however, the brush wheel configured in the conventional wall washer is not conducive to disassembly and replacement. Problems that need improvement.
