Description

Technical Field

[0001] This invention belongs to the field of cleaning technology, and specifically relates to a glass curtain wall cleaning device. Background Technology

[0002] Chinese patent application number 202010955718.1 discloses a glass curtain wall cleaning device, which can move and clean the outer wall of the glass curtain wall from top to bottom by using an electric hoist. Compared with the traditional manual cleaning method, it can save some physical strength and speed up the cleaning efficiency. The separate arrangement of the upper cleaning scraper, lower cleaning scraper, spray pipe and cleaning head can achieve a near dry and wet separation effect, thereby enhancing the cleaning effect.

[0003] However, the cleaning head of this device is in a fixed position, which limits the range of glass curtain wall cleaning. It cannot clean large glass curtain walls as a whole. When it is necessary to increase the cleaning range, the overall position needs to be changed by hoisting, which increases the difficulty of the work. It is not convenient to increase the cleaning range and has poor practicality. Utility Model Content

[0040] The first electric slide rail, the second electric slide rail, the first sliding component, the second sliding component, the spray head, the foam nozzle, the control box, the proportioning pump, the first water pump, the second water pump, and the cylinder in this case are existing technologies. As long as the first electric slide rail, the second electric slide rail, the first sliding component, the second sliding component, the spray head, the foam nozzle, the control box, the proportioning pump, the first water pump, the second water pump, and the cylinder meet the requirements of this case, they are all acceptable and not limited to a single model.

[0041] Working Principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions before use. During use, connect the external hoisting equipment to the lifting lug 29, then lower the hoisting box 1 from the roof, with one side of the water spray head 9 and foam spray head 10 facing the glass curtain wall. When the hoisting box 1 moves to the glass curtain wall to be cleaned, first activate the second electric slide rail 3 and the second water pump 24. The second electric slide rail 3 drives the second sliding member 5 to move back and forth. The second water pump 24 draws water from the water storage tank 15 into the proportioning pump 17 through the second inlet pipe 25. Then, the proportioning pump 17 draws foam concentrate into the proportioning pump 17 through the second connecting pipe 27 and mixes it with water in a proportional ratio. Then, the mixture is input into the foam spray head 10 through the second drain pipe 19, and the foam spray head 10 cleans the glass curtain wall. Foam is sprayed; after the foam is sprayed onto the glass curtain wall, the first water pump 21 is started. The first water pump 21 discharges water from the water storage tank 15 into the spray head 9 through the first water inlet pipe 22 to rinse the part sprayed with foam; after rinsing the entire horizontal width of the glass curtain wall, the external lifting equipment lowers the hoisting box 1, so that the spray head 9 and foam nozzle 10 rinse the next height. When rinsing the curtain wall at the next height, the rinsing liquid flowing down from above will increase the rinsing density below, improving rinsing efficiency; then the brush plate 72 is lowered to the height just rinsed, and the cylinder 63 is started, so that the cylinder 63 drives the second housing 62 to slide outward through the output shaft 64, so that the brush plate 72 fits against the glass curtain wall. Then the first electric slide rail 2 is started, and the first electric slide rail 2 drives the first sliding member 4 to move back and forth, thereby driving the brush plate 72 to clean the glass curtain wall, thereby increasing the cleaning range.

[0042] When the brush plate 72 needs to be replaced, the user needs to pull the lifting button 734 outward to move the locking lever 733, causing the locking lever 733 to disengage from the slot 732. Then the user can remove the insert plate 75 from the mounting slot 74. The user then takes out the new brush plate 72, inserts part of the insert plate 75 into the mounting slot 74, and then pulls the lifting button 734 outward. After the locking lever 733 disengages from the mounting slot 74, the user then fully inserts the insert plate 75 into the mounting slot 74, so that the locking lever 733 is aligned with the slot 732, thus completing the fixation of the brush plate 72.
