[0001] The utility model relates to the technical field of building exterior wall cleaning, in particular to a building exterior wall cleaning device. Background Art

[0002] The exterior wall of a building is the side of a building facing the outside world. It not only undertakes basic functions such as sheltering from wind and rain, and heat insulation, but is also an important manifestation of architectural aesthetics. It is related to the image and quality of the entire building. The exterior wall of a building is exposed to the outside for a long time, and it is easy to adhere to a layer of dust and affect the appearance. Therefore, the exterior wall of the building needs to be washed and cleaned after a period of time.

[0003] At present, some shorter exterior walls are mostly scrubbed by workers using brushes. Since it requires vigorous scrubbing, it consumes a lot of time and energy. Based on this, in the patent with patent number 202222290726.6, a building exterior wall cleaning device is disclosed. In the disclosed cleaning device, a brush is driven to rotate by a motor, thereby saving the effort of manual scrubbing. However, it still needs to be manually sprayed with water during use, which is also quite laborious, and it is impossible to synchronize the spraying with the cleaning, thus affecting the cleaning effect. Secondly, when flushing and cleaning the exterior walls of buildings, a large amount of water directly flows down the wall to the ground, which wastes water resources. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Figure 1-Figure 3 All of them are schematic diagrams of the overall structure of the utility model. As shown in the figure, the building exterior wall cleaning device includes a base plate 1, and a moving wheel 17 is installed at the bottom end of the base plate 1. The moving wheel 17 is provided with at least four. The moving wheel 17 facilitates the movement of the cleaning device, and a push plate 16 is fixed at one end of the base plate 1. The outer wall of the push plate 16 is installed with a grip rod 20. The grip rod 20 is used to push and pull the cleaning device, which is convenient for the staff to apply force. Secondly, a mounting box 3 is fixed in the middle of the upper end surface of the base plate 1, and a hydraulic cylinder 4 is installed inside the mounting box 3. A mounting plate 5 is installed at the output end of the hydraulic cylinder 4, and a telescopic arm 6 is installed on the upper end surface of the mounting plate 5. A brush mounting part 7 is installed at the top of the telescopic arm 6, and a soft brush part 8 is installed on the outer wall of the brush mounting part 7. The telescopic arm 6 is preferably an electric telescopic rod or a pneumatic telescopic rod, and the height of the brush mounting part 7 is adjusted up and down by the telescopic arm 6.

[0027] In addition, see Figure 1 and Figure 3 As shown, a water tank 2 is installed on the upper end surface of the bottom plate 1 and on one side of the installation box 3. Clean water is contained in the water tank 2. A water pump 9 is installed at the bottom end of the outer wall of the water tank 2 through a pipeline. A water supply pipe is installed at the water outlet of the water pump 9. The water supply pipe is at least partially a hose, and the water supply pipe passes through the bristle mounting portion 7. A water spray pipe 11 is vertically installed at the top of the water supply pipe. A plurality of nozzles 12 are equidistantly installed on the outer wall of the water spray pipe 11 through a plurality of water distribution pipes. The outward extension length of the nozzle 12 is less than the outward extension length of the soft bristle portion 8.

[0028] The water supply pipe includes a connected water supply hose 10 and a water supply hard pipe 18 . One end of the water supply hose 10 away from the water supply hard pipe 18 is connected to the water outlet end of the water pump 9 . The water supply hard pipe 18 penetrates and is fixed on the bristle mounting part 7 .

[0029] Through the above technical solution:

[0030] During specific use, the cleaning device can be manually moved to the exterior wall of the building to be cleaned, and the overall position can be adjusted so that the soft brush part 8 fits the exterior wall of the building. Then, power can be turned on, and then the water pump 9 and the telescopic arm 6 can be started. The telescopic arm 6 can be used to drive the brush mounting part 7 to move up and down to clean the exterior wall. While cleaning, the water pump 9 draws water from the water tank 2, and sends it to the water supply hard pipe 18 through the water supply hose 10, and then sends it to multiple nozzles 12 through the water spray pipe 11 and sprays it on the exterior wall. It can achieve cleaning while spraying water, which is more convenient and has better effects. Secondly, the water volume can be controlled as needed while spraying water, thereby saving water resources.

[0031] When the telescopic arm 6 is raised or lowered, the water supply pipe 18 connected through the water supply hose 10 can be raised or lowered synchronously, thereby ensuring that water is always sprayed from the upper end of the soft bristle part 8 toward the outer wall, thereby improving the water spraying effect.

[0032] After cleaning one section of the building's exterior wall, the staff will move the device to a different position for further cleaning, and continue this process until the entire exterior wall is cleaned.

[0033] Also, see Figure 1 and Figure 4 As shown, a telescopic rod 13 in the same direction as the hydraulic cylinder 4 is also installed on the base plate 1. The telescopic rod 13 is preferably an electric telescopic rod. A water receiving plate 15 is installed at the output end of the telescopic rod 13. A water collecting trough 21 is provided on the upper end surface of the water receiving plate 15. Leakage ports 22 are provided at both ends of the water collecting trough 21. A water receiving box 14 is provided on the lower end surface of the water receiving plate 15. A filter screen is installed inside the leakage port 22. The filter screen can block impurities and prevent impurities from entering the water receiving box 14. A drain pipe 19 is connected to the bottom end of the outer wall of the water receiving box 14. The drain pipe 19 is a hose and can be connected to a larger collection box for collecting water. The water in the collection box can be replenished in the water tank 2 for use, thereby saving water resources and reducing the waste of water resources.

[0034] Through the above, after the soft bristle part 8 is in contact with the outer wall of the building, the telescopic rod 13 can be used to drive the water receiving plate 15 and the water receiving box 14 to extend outward, so that the water receiving plate 15 is also in contact with the outer wall of the building. In this way, when spraying water for cleaning, the water flowing down the wall can enter the water collecting trough 21 on the water receiving plate 15, and then enter the water receiving box 14 through the leakage port 22 for collection. The water in the water receiving box 14 can be discharged through the drain pipe 19 for collection and reuse, thereby reducing the waste of water resources.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
