Description

Technical Field

[0001] The present invention relates to the technical field of automatic cleaning devices, and particularly to an automatic cleaning device for the outer wall glass of high-rise buildings. Background Art

[0002] As is well known, with the continuous development of the construction industry in China, more and more high-rise buildings adopt glass curtain walls as the exterior facade design. However, with the use of glass curtain walls, once dust accumulates on the facade glass of the glass curtain wall, it not only affects the beauty of the building, but also affects the actual use effects and safety issues in many aspects. An automatic cleaning device for the outer wall glass of high-rise buildings is an auxiliary device proposed to achieve the automatic cleaning of glass curtain walls.

[0003] After retrieval, the patent with the Chinese patent publication number CN113086198A and the patent with the Chinese patent publication number CN108720708A respectively disclose a portable drone for cleaning the outer wall glass of high-rise buildings and a cleaning device for the outer glass of high-rise buildings. The former is roughly described as including a bottom plate. Storage holes are provided at the four corners of the bottom plate. A gear is fixedly installed on the outside of the rotating shaft. Connecting rods are fixedly installed on one side of each gear. A folding driving device is installed on one surface of the bottom plate. Installation blocks are symmetrically installed on both sides of the bottom plate. A first roller motor and a second roller motor are respectively installed between the two installation blocks on the same side. A rag is wound around the outside of the cylinder. The two ends of the rag are respectively fixed to the first roller motor and the second roller motor. When in use, when cleaning the glass, the motor is started, the motor drives the fan blades to rotate, the drone is lifted, the surrounding situation can be observed through the camera, the water pump is started, the water in the water tank is sprayed onto the glass through the nozzle, the second roller motor and the first roller motor are started, and the second roller motor and the first roller motor rotate in the same direction, which can drive the rag to rotate, and the rag realizes the cleaning of the glass. The latter is roughly described as including a base. A lifting mechanism is fixedly installed at the upper end of the base. The base is connected to a support plate through the lifting mechanism. A fixing column is fixedly connected to the upper end of the support plate. A first bevel gear is welded to the outside of the fixing column. A fixing platform is fixedly connected to the upper end of the fixing column. A motor is fixedly installed on the fixing platform. A movable seat is fixedly connected to the output rod of the motor. Two limiting seats are fixedly connected to the bottom end of the movable seat. A first rotating rod is rotatably connected through the two limiting seats. One end of the first rotating rod is rotatably connected to the side wall of the movable seat. When in use, the driving rod of the driving cylinder extends, pushing the second support column and the first support column to move to lift the support plate, so that the installation plate reaches the required cleaning floor height.

[0004] Although the above two prior art solutions can achieve the auxiliary cleaning of the facade glass in the glass curtain wall, the former uses the flight assistance of a drone to adjust the cleaning height. The drone needs to maintain a certain stability during flight to ensure the cleaning effect. Moreover, the flight power of the drone is limited, and unnecessary dangers are likely to be caused in case of flight failure. The latter uses the extension of the driving rod of the driving cylinder to push the second support column and the first support column to move and lift the support plate, so that the mounting plate reaches the required cleaning floor height adjustment form. Obviously, the lifting height of the mounting plate is limited, so the cleaning height is also limited. Summary of the Invention

[0045] In summary, the working principle of the automatic cleaning device for the exterior facade glass of high-rise buildings is as follows. Before use, first install the parallelogram top frame 33 brackets at the top of the high-rise building, and install the parallelogram bottom frame 34 on the side of the high-rise building near the facade glass below. By controlling the operation of the top winch 35, the retraction and release control of the traction rope 16 is realized, so that the traction rope 16 is lowered from the top of the high-rise building. Then, connect the two traction ropes 16 to the two inner liners 14 respectively. After that, when the top winch 35 works, the height adjustment of the two inner liners 14 can be realized through the traction rope 16, and then the height adjustment of the whole cleaning system can be realized. Connect the two outer connecting pipes to the external supply pump and adsorption pump. The supply pump sends the external cleaning water into the water supply channel 22 through the outer communication ring 24. When the outer guiding pipe 28 rotates and communicates with the water supply hole 26, the cleaning water will pass through the water supply hole 26, the outer guiding pipe 28 and the external telescopic pipe 30 and enter the water replenishing cavity 29, and finally be conveyed relative to the cleaning component 10 on the arc-shaped pressing plate 9 through the capillary water passing holes 31 to realize the wetting of the cleaning component 10, which is convenient for the cleaning component 10 to clean the facade glass. When the outer guiding pipe 28 rotates and communicates with the water absorption hole 27, the adsorption pump will control the water replenishing cavity 29 to form a negative pressure to assist in pumping out the water and sundries on the cleaning component 10 to realize the cleaning of the cleaning component 10, and then facilitate the repeated use of the cleaning component 10. During the cleaning operation, by controlling the operation of the two top electric telescopic rods 39, the rotation control of the two top guiding frames 38 is realized to facilitate the approach control of the two traction ropes 16 relative to the facade glass. By controlling the operation of the two bottom electric telescopic rods 43, the rotation control of the two bottom guiding frames 42 is realized to facilitate the approach control of the two stabilizing ropes 17 relative to the facade glass. By controlling the relative distance between the traction rope 16 and the facade glass and the relative distance between the stabilizing rope 17 and the facade glass, the contact and pressing control of the two stabilizing suction cups 1 relative to the facade glass is realized, so that the elastic suction cups 62 facing the facade glass on the inner side of the two stabilizing suction cups 1 are adsorbed relative to the facade glass. Then, through the coordinated operation of the top winch 35 and the bottom winch 36, the matching adjustment of the traction rope 16 and the stabilizing rope 17 is realized, forming the relative rolling of the cleaning system relative to the facade glass. That is, when the traction rope 16 is retracted by the top winch 35, the stabilizing rope 17 is released by the bottom winch 36 in a supporting manner. At this time, the cleaning system rolls up relative to the facade glass. When the traction rope 16 is relaxed by the top winch 35, the stabilizing rope 17 is retracted by the bottom winch 36 in a supporting manner. At this time, the cleaning system rolls down relative to the facade glass. During the process of the cleaning system rolling relative to the facade glass and forming a height change, multiple elastic suction cups 62 are sequentially adsorbed and separated relative to the facade glass to ensure the smooth rolling of the stabilizing suction cup 1 relative to the facade glass.

[0046] Furthermore, the docking shaft 3 and the cross shaft 2 are respectively provided with a plugging groove and a plugging plate. When the docking shaft 3 and the cross shaft 2 are connected to each other, the plugging plate is inserted into the plugging groove and is assisted in positioning in the plugging groove through a plugging bolt. When the stability-maintaining suction cup 1 connected to the docking shaft 3 rolls relative to the facade glass, it will drive the docking shaft 3 and the cross shaft 2 to rotate synchronously. The rotation of the cross shaft 2 will drive the driving internal gear ring 18 to rotate. The rotation of the driving internal gear ring 18 will drive the rotation of the linkage internal gear ring 19 through the stepped transmission gear 21. The rotation of the linkage internal gear ring 19 will drive the first cleaning frame 5 and the second cleaning frame 6 to rotate through the rotating frame 4. The rotation of the first cleaning frame 5 and the second cleaning frame 6 will drive a plurality of arc-shaped pressing plates 9 to rotate synchronously through a plurality of linkage frames 8, so as to finally drive the rotation of a plurality of cleaning accessories 10. And the rotation directions of the plurality of cleaning accessories 10 are opposite to the rotation direction of the stability-maintaining suction cup 1, reducing the influence of the movement of the cleaning accessories 10 on the area of the facade glass that has been cleaned, improving the overall cleaning quality of the facade glass. And under the transmission effect between the corrugated track frame 11 and the plurality of linkage rods 12, when the plurality of linkage frames 8 rotate, they will form a lateral movement in the side stepped opening 7, so that the cleaning accessories 10 can form a lateral scrubbing movement while rotating relative to the facade glass for cleaning, enriching the movement cleaning track of the cleaning accessories 10 relative to the facade glass. The cleaning accessories 10 are made of an elastic material with good hydrophilic effect, and the arc-shaped pressing plates 9 are made of a water-permeable material or a water-permeable structure to facilitate the conduction of cleaning water between the water replenishing cavity 29 and the cleaning accessories 10. The parallelogram top frame 33 and the parallelogram bottom frame 34 are unfolded into a rectangular frame structure during use and can be folded into a narrow state for convenient handling after use, as shown in the appendix Figure 19 The figure shows the folded state of the parallelogram top frame 33. When the groove threaded block 53 and the threaded rod 52 are in a spiral connection state, by rotating the threaded rod 52, the driving bar frame 49 can be rotated and adjusted relative to the parallelogram top frame 33. Therefore, to facilitate the adjustment of the suspension bracket 37 relative to the parallelogram top frame 33, by rotating one of the two auxiliary adjustment screws 56, the threaded connection effect between the corresponding groove threaded block 53 and the threaded rod 52 is invalidated. In this way, only the other threaded rod 52 needs to be rotated to realize the adjustment of the driving bar frame 49 relative to the parallelogram top frame 33. After the adjustment is completed, to ensure the bracket stability of the suspension bracket 37 relative to the parallelogram top frame 33, by adjusting the corresponding auxiliary adjustment screw 56, the groove threaded block 53 with the invalidated threaded connection effect is made to form a valid threaded connection with the corresponding threaded rod 52 again, so that both driving bar frames 49 have a supporting effect, improving the stability of the relative bracket structure of the suspension bracket 37 relative to the parallelogram top frame 33.
