By providing the driving device 2122 and the connecting block 2124, the driving device 2122 can drive the connecting block 2124 and the cleaning box 2101 to move, thereby providing power for the movement of the cleaning box 2101; See also Figure 2 and Figure 3 The front of the cleaning box 2101 is fixedly connected with a stepper motor 2125, and the output end of the stepper motor 2125 is fixedly connected with a threaded shaft 2130, and the outer surface of the threaded shaft 2130 is rotatably connected to the inner wall of the cleaning box 2101, and the outer surface of the threaded shaft 2130 is threadedly connected with a moving plate 2127. By providing the stepper motor 2125, the threaded shaft 2130 and the moving plate 2127, the operation of the stepper motor 2125 can drive the threaded shaft 2130 to rotate, and the threaded connection relationship between the threaded shaft 2130 and the moving plate 2127 can drive the moving plate 2127 to move; See also Figure 2 and Figure 3 The inner wall of the cleaning box 2101 is fixedly connected to two second guide rods 2129, and the outer surface of each second guide rod 2129 is slidably connected to the inside of the movable plate 2127. By providing the second guide rods 2129, the second guide rods 2129 can limit the moving range of the movable plate 2127 to prevent the movable plate 2127 from rotating; See also Figure 3 and Figure 4 The bottom surface of the movable plate 2127 is fixedly connected with a movable block 2135, the inner wall of the movable block 2135 is rotatably connected with a rotating shaft 2138, the right end of the rotating shaft 2138 is fixedly connected with a cleaning plate 2128, the right side of the cleaning plate 2128 is in contact with the left side of the building exterior wall 1, and by providing the movable block 2135, the rotating shaft 2138 and the cleaning plate 2128, the movable block 2135 can move along with the movement of the movable plate 2127, thereby driving the cleaning plate 2128 to move horizontally, so as to ensure that the wall surface covered by the cleaning box 2101 is fully cleaned; See also Figure 4The inner wall of the cleaning box 2101 is fixedly connected with a toothed plate 2133, the outer surface of the toothed plate 2133 is meshed with a first gear 2134, the inner wall of the first gear 2134 is fixedly connected to the outer surface of the rotating shaft 2138, by providing the toothed plate 2133 and the first gear 2134, utilizing the meshing relationship between the first gear 2134 and the toothed plate 2133, the first gear 2134 can be rotated while following the horizontal movement of the rotating shaft 2138, thereby driving the cleaning plate 2128 to move horizontally while rotating itself; See also Figure 5 The inner wall of the cleaning box 2101 is fixedly connected with a partition 2132, the upper surface of the partition 2132 is fixedly connected with a water storage tank 2126, the upper surface of the partition 2132 is fixedly connected with a water pump 2136, the input end of the water pump 2136 is fixedly connected with a water pumping pipe 2137, the left end of the water pumping pipe 2137 passes through the interior of the water storage tank 2126, the output end of the water pump 2136 is fixedly connected with a water outlet pipe 2131, and the upper surface of the cleaning box 2101 is fixedly connected with a water injection pipe 2123. By providing the water pump 2136, the clean water inside the water storage tank 2126 can be pumped out by using the water pump 2136 and the water pumping pipe 2137, and sprayed on the wall through the water outlet pipe 2131.

[0024] The specific implementation of this embodiment is as follows: when the device is needed to be used, the driving device 2122 needs to be installed in a suitable position first. It should be understood here that the driving device 2122 can be divided into two parts, each of which is composed of a motor, a winding roller and a rope, and the two parts of the driving device 2122 need to be installed on the roof and the bottom of the building respectively. Thus, when the two motors in the driving device 2122 are running, the motor located on the roof drives the winding roller to implement the wire-releasing action, and the motor located at the bottom of the building drives the winding roller to implement the wire-reeling action, thereby driving the cleaning box 2101 to move from the upper floor of the building to the lower floor. During the movement of the cleaning box 2101, the stepper motor 2125 and the water pump 2136 can be controlled to operate, and the operation of the stepper motor 2125 will drive the cleaning plate 2128 moves and rotates at the same time to clean the wall, and the water pump 2136 can pump out the clean water in the water tank 2126 and spray it on the wall. In addition, since the cleaning box 2101 does not contact the left side of the building's outer wall 1, it can ensure that the rotating roller 2104 and the cleaning plate 2128 rotating on the inner wall of the cleaning box 2101 have sufficient pressure to closely contact the wall, and the outer surface of the rotating roller 2104 is covered with a layer of rubber, so the friction coefficient of the rotating roller 2104 is very large. Therefore, when the cleaning box 2101 is moved downward by the driving device 2122, the rotating roller 2104 will rotate under the friction of the wall, and the rotating roller 2104 will be driven by the first transmission gear belt group 2108 when rotating. The rotational power received is transmitted to the transmission shaft 2107, and then it can be transmitted to the gear box 2109, and the gear speed change structure inside the gear box 2109 can convert the input rotational power into a rotational power with a higher rotation speed, and transmit it to the reciprocating screw 2103, thereby driving the reciprocating screw 2103 to rotate. It should be understood here that the reciprocating screw 2103 is usually composed of two thread grooves with the same pitch and opposite rotation direction. These two thread grooves are located on both sides of the same screw rod. When the reciprocating screw 2103 rotates, the side of the thread groove will push the reciprocating block 2118 located in the thread groove, so that the reciprocating block 2118 performs a linear reciprocating motion along the axis of the screw. Due to the design of the thread groove, the reciprocating block 2118 will be moved to one end of the screw. The transition curve guides back to the thread groove at the other end, thereby realizing continuous reciprocating motion. Therefore, the reciprocating ring 2119, the reciprocating plate 2111, the reciprocating frame 2113 and the structure inside the reciprocating frame 2113 fixed on the outer surface of the reciprocating block 2118 will also make corresponding reciprocating motions, and the reciprocating plate 2111 will only perform lateral parallel movement under the limitation of the two first guide rods 2106, and will not rotate. In addition, a reset shaft 2116 slides inside the reciprocating frame 2113, and the rectangular block 2120 fixed on the outer surface of the reset shaft 2116 and the rotating plate 2121 rotating on the inner wall of the rectangular block 2120 will pull the reset plate 2114 to move under the guidance of the guide plate 2102. When the rotating plate 2121 moves to the leftmost side of the guide plate 2102,The reset plate 2114 will push the reset spring 2117 to be in an extruded state, and when the rotating plate 2121 moves out of the leftmost side of the guide plate 2102, the rotating plate 2121, the rectangular block 2120, the reset shaft 2116 and the reset plate 2114 will rebound quickly under the action of the reset spring 2117, so that the knocking block 2115 on the right side of the reset plate 2114 can be used to knock on the wall surface, causing some relatively fragile wall skins to fall off. After being knocked, the wall skins will fall downward until they fall into the angle between the rotating roller 2104 and the building outer wall 1. Some larger wall skins will rotate to the inside of the collection frame 2105 with the rotation of the rotating roller 2104, and some smaller wall skins will enter the groove 2112 opened on the outer surface of the rotating roller 2104 with the rotation of the rotating roller 2104, until the entrance of the groove 2112 faces downward, and the fragmented wall skins inside the rotating roller 2104 will enter the collection frame 2105.

By setting a sewage recovery unit 22, the sewage recovered from the wall surface can be recovered by the sewage recovery unit 22, thereby avoiding the problem that the used cleaning water will flow down the wall surface, which increases the difficulty of cleaning the fragile wall skin.

[0027] The specific implementation of this embodiment is as follows: when the cleaning box 2101 is descending, the clean water in the water tank 2126 will be pumped out by the water pump 2136 and sprayed on the building outer wall 1. The clean water on the building outer wall 1 will flow downward under the action of gravity until it flows to the surface of the transmission belt 2204. The outer surface of the transmission belt 2204 is covered with a layer of absorbent sponge, so the used sewage will be absorbed by the absorbent sponge, and the transmission belt 2204 can circulate under the action of the second gear 2209. When the transmission belt 2204 area with sewage passes through the squeezing roller 2207, the squeezing roller 2207 will squeeze the sewage in the transmission belt 2204 until the sewage enters. The sewage will enter the interior of the recycling box 2211, and the sewage will first pass through the filter plate 2203 before falling into the recycling box 2211. The impurities in the water can be simply filtered under the filtration of the filter plate 2203. When you want to remove the filter plate 2203, you only need to rotate the limit plate 2210 so that the limit plate 2210 is no longer in contact with the filter plate 2203, and the filter plate 2203 can be pulled out. The rotation of the second gear 2209 depends on the second transmission gear belt group 2206 to transmit the rotational power on the transmission shaft 2107 to the extension shaft 2205 and the second gear 2209. Therefore, when the cleaning box 2101 moves downward, the transmission belt 2204 will rotate accordingly.

The plurality of suction cups 308 are connected to the plurality of suction cups 309. The cleaning box 2101 is rotatably connected to the inside of the rectangular plate 305, and the inner wall of the cleaning box 2101 is rotatably connected to the first rotating shaft 301 and the second rotating shaft 313 respectively. The inner wall of the cleaning box 2101 is fixedly connected to the gear change box 312, and the input end of the gear change box 312 is fixedly connected to the end of the second rotating shaft 313 close to the gear change box 312. The output end of the gear change box 312 is fixedly connected to the end of the first rotating shaft 301 close to the gear change box 312. The outer surface of the first rotating shaft 301 is fixedly connected to the gear change box 312. 2. The outer surface of the first rotating shaft 301 is fixedly connected with the rotating block 302, and the outer surface of the second rotating shaft 313 and the outer surface of the rotating roller 2104 are fixedly connected with the third transmission gear belt group 303. By setting a stabilizing mechanism 3, the device can be adsorbed on the wall by using the stabilizing mechanism 3. By setting the mutual cooperation between the knocking unit 21, the sewage recovery unit 22 and the stabilizing mechanism 3, the problem of the device affecting nearby workers and vehicles due to falling wall skin and sudden weather during use can be effectively avoided.

[0030] The specific implementation of this embodiment is as follows: when encountering sudden weather, the cleaning box 2101 can continue to be controlled to move downward. When the rotating roller 2104 rotating on the inner wall of the cleaning box 2101 rotates with the left side of the building outer wall 1, the rotating roller 2104 will transmit power to the second rotating shaft 313 through the third transmission gear belt group 303, and the second rotating shaft 313 will transmit power to the gear change box 312. Through the gear steering structure in the gear change box 312, the rotational power in the opposite direction can be output to the first rotating shaft 301. The rotation of the first rotating shaft 301 will drive the rotating block 302 to rotate. When the rotating block 302 rotates to one side of the force-bearing plate 311, it will push the force-bearing plate 311 to move, thereby pushing the moving frame 306 fixed on the upper surface of the force-bearing plate 311 to move toward the left side of the building outer wall 1 until the suction cup 308 contacts the building outer wall 1. At this time, the air pump 309 is controlled to operate, and the air can be sucked through the multi-directional air suction pipe 3 07 The air between the suction cup 308 and the building's exterior wall 1 is extracted, so that the moving frame 306 can be adsorbed on the left side of the building's exterior wall 1. It should be understood here that since the rotation speed of the rotating roller 2104 is the same as that of the first rotating shaft 301, it means that every time the rotating roller 2104 rotates one circle, the rotating block 302 fixed on the outer surface of the first rotating shaft 301 will push the force plate 311, the moving frame 306 and the suction cup 308 to contact the left side of the building's exterior wall 1 once. Since the cleaning diameter of the cleaning plate 2128 is the same as the circumference of the rotating roller 2104, every time the rotating roller 2104 rotates one circle, the suction cup 308 will be adsorbed on the left side of the building's exterior wall 1 under the action of the vacuum pump 309. At this time, the cleaning plate 2128 just drops to the junction of the uncleaned wall surface and the cleaned wall surface. Therefore, the stabilizing mechanism 3 can not only ensure the safety of the cleaning box 2101 in the event of an emergency, but also ensure the stability of its operation under normal working conditions.
