Abstract

PURPOSE:To make it possible to perform the cleaning of a window with a high efficiency and safety regardless of time and weather by employing a window cleaning machine, a device for moving to a cleaning position, and a monitoring device. CONSTITUTION:A cart 11 is provided with a nozzle 14 for injecting a cleaning liquid, a wiper blade 15, a sealing device 16 for preventing scatter of the cleaning liquid, and a cable 17 for power or signal supply. A control device 36 detects a cleaning position to drive or stop the cart 11. Disposing guide rails of the cart 11 on a wall surface of a building, a monitoring device 38 makes it possible to control or monitor the cleaning condition of the cart 11. As a result, window cleaning is performed with a high efficiency and safety regardless of time and weather.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an apparatus for automatically cleaning window glass of a high-rise building.

[Conventional technology and its challenges] Window cleaning in high-rise buildings involves two or three cleaners riding a gondola suspended from the roof using wires, and sequentially moving the gondola up and down or left and right along the wall. I move around and clean the windows.

However, in the case of skyscrapers, manual methods have many problems, such as the time it takes to clean the windows, the inability to clean the windows in stormy weather or at night, and safety issues.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an automatic window cleaning device that can clean windows safely and efficiently, regardless of time or weather.

[Means and effects for solving the problems] The automatic window cleaning device according to the present invention includes a cleaning liquid spray nozzle, a wiper blade, a sealing device for preventing the cleaning liquid from scattering, and a power supply or signal cable. It includes a cart, a drive control device that detects a cleaning position and drives or stops the cart, a guide rail for the cart provided on a wall of a building, and a monitoring device that can monitor or control the cleaning status of the cart. It is characterized by

Targeting a building where the shape and arrangement of windows are constant, a reference position is determined for each unit of windows, this is detected by the drive control device, the trolley is stopped at a predetermined position, and the sealing device is installed. The cleaning liquid supplied from the cleaning liquid tank is then sprayed onto the window glass using a spray nozzle, the glass surface is wiped with a wiper blade, and the drained cleaning liquid is stored in the waste liquid tank. be done.

Next, the seal by the sealing device is removed to complete the cleaning of one unit of window, and the cart is moved to the next adjacent cleaning position to repeat the cleaning operation. Further, the cleaning status of the trolley can be monitored indoors by the monitoring device, and necessary instructions or work can be given in response to transient or abnormal conditions.

[Examples] Examples of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view of the automatic window cleaning device of this embodiment,
FIG. 2 is a front view of the device. Reference numeral 11 denotes a trolley, on which are provided a cleaning liquid tank 12, a drainage tank 13, a cleaning liquid injection nozzle 14, a wiper blade 15, tires 16 for preventing the cleaning liquid from scattering, and a power supply or signal cable 17. Further, an electric drive device (not shown) is provided for making the traveling bogie run along the rail 32 shown in FIG. 35 and a drive control device 36 are provided on the truck 11. Furthermore, trolley 1
A monitoring device 38 for monitoring the cleaning work of No. 1 is installed indoors in the building.

The operation of the automatic window cleaning device configured as above will be explained. The drive control device 36 receives a signal from the transmitter 33 and operates the electric drive device to move the trolley 11 to the cleaning position, where it is stopped.

Next, the gap between the window frame 31 and the lower surface of the truck 11 is sealed by inflating a tire, which is a sealing device provided to prevent scattering of the cleaning liquid or to collect waste liquid, with compressed air. After that, the cleaning liquid is sprayed from the cleaning liquid tank 12 onto the window glass 34 by the injection nozzle 14 via a pressure pump (not shown), and the wiper 15 wipes the glass 34 from top to bottom.
The drained liquid at this time is collected in the waste liquid tank 13.Then, after the tires 16 are deflated, the truck 11 is moved toward the next cleaning position, and the above operation is repeated.

Replenishment of cleaning liquid in the cleaning liquid tank 12, disposal of waste liquid in the waste liquid tank 13, transitional processing such as switching from vertical to horizontal movement of the cart 11 or from horizontal to vertical movement, or abnormality in the drive or cleaning function of the cart 11, etc. For countermeasures, please refer to Cable 17
A monitoring device 38 installed indoors receives signals from the vehicle, and can detect a transient state or an abnormal state, and can take appropriate measures accordingly.

[Effects of the Invention] The automatic window cleaning device of the present invention has a window cleaning device that can perform automatic cleaning, a device for moving to the cleaning position, and a monitoring device, so it can achieve high efficiency regardless of time or weather. You can safely clean windows with this.
