DETAILED DESCRIPTION

[0027] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, same numbers refer to same elements in all figures. The following exemplary embodiments are not intended to represent all embodiments in accordance with the present application. Rather, they are merely examples of apparatuses or methods in accordance with some aspects of the present application.

[0028] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some, but not all of the embodiments in accordance with the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0029] The embodiments will be described below with reference to the drawings. In addition, the embodiments shown below do not limit the present application in any way. Furthermore, the entire contents of the embodiments shown below are not limited to what is necessary for solving the problems of the present application.

[0030] Reference will now be made to Figures 1-8The utility model provides a glass curtain wall cleaning device, apply to the cleaning of glass curtain wall with longitudinal beam outside. It includes: guide rail 11, guide rail 11 extends along the longitudinal direction, guide rail 11 can be arranged on the longitudinal beam of glass curtain wall, guide rail 11 can be installed in sections, and is formed by splicing. Specifically, according to the need, a guide rail 11 can be arranged on each longitudinal beam, or a guide rail 11 can be arranged every several longitudinal beams. The cleaning head 2 is movably arranged on the guide rail 11. The guide rail 11 is used to constrain the cleaning head 2 to move in the direction perpendicular to the glass curtain wall, so as to prevent the back impact force generated when the cleaning head 2 washes the glass curtain wall from moving the cleaning head 2 away from the glass curtain wall, thereby causing the distance between the cleaning head 2 and the glass curtain wall to increase and affecting the washing effect. It also includes a first driving device, a first pressurizing device 61 and a first liquid supply device 62, and the first pressurizing device 61 and the first liquid supply device 62 are arranged on the top of the building. The first driving device is used to drive the cleaning head 2 to move along the guide rail 11. The guide rail 11 can be provided with a sliding block 12, and the cleaning head 2 is fixedly connected with the sliding block 12 through a locking piece 13. Since the overall weight of the cleaning head 2 is not large, the connecting force between the first driving device and the cleaning head 2 can bear the gravity of the cleaning head 2. Of course, in some cases, a hoisting rope can also be arranged on the cleaning head 2, and the hoisting rope is used to provide a pulling force during the up and down movement of the cleaning head 2, so as to offset the gravity of the cleaning head 2. The cleaning head 2 includes a first horizontal pipe 21, which extends in the transverse direction. The length of the first horizontal pipe 21 can be determined according to the width of the area to be cleaned. The first horizontal pipe 21 can be of an integrated structure or a spliced structure. The first horizontal pipe 21 is provided with a first nozzle 211, which is used to spray liquid with a certain pressure. The pressure can be set according to the need, and the pressure can be greater than 2MPa, preferably 4-10MPa. The first horizontal pipe 21 is connected with the first pressurizing device 61 through a first conveying pipe 31, and the first pressurizing device 61 is connected with the first liquid supply device 62. When the cleaning head 2 moves downward, the first conveying pipe 31 is elongated or released, and when the cleaning head 2 moves upward, the first conveying pipe 31 is retracted or recovered.

[0031] When the first liquid supply device 62 is a liquid storage tank, it can be filled with cleaning liquid capable of directly cleaning the glass, and the cleaning liquid does not need to be washed with clean water after washing the glass, such as glass water and the like. The first liquid supply device 62 can also be filled with clean water. Under the action of the first pressurizing device 61, the cleaning liquid or the clean water is pressurized and then enters the first horizontal pipe 21 through the first delivery pipe 31, and finally is sprayed out from the first spray head 211. Since the cleaning liquid or the clean water has a certain pressure, the glass curtain wall can be washed, and the contaminants on the glass curtain wall can be washed away. The first driving device controls the cleaning head 2 to move up and down along the guide rail 11, from top to bottom or from bottom to top, so that the glass curtain wall is washed clean.

[0032] The utility model discloses a first horizontal pipe and a first spray head are arranged on the cleaning head, a first pressurizing device is used for pressurizing, so that the liquid with certain pressure is sprayed out from the first spray head to wash the glass, which replaces the rubber scraping strip used in the prior art to scrape the glass. The rubber scraping strip, which is a wearing and consuming part, is not used any more, and the maintenance frequency can be reduced. In addition, the cleaning head is driven to move up and down along the guide rail by the first driving device, so that the cleaning of the entire glass curtain wall can be completed. Compared with manual cleaning, the cleaning efficiency is higher, and the safety risk caused by the high-altitude operation of workers can be avoided.

[0033] Of course, a sewage collecting device can be arranged at the bottom of the glass curtain wall or on the ground, and the water used for washing the glass curtain wall can be collected by the sewage collecting device and then purified.
