A plurality of water outlet holes are provided on the side of the rotating nozzles 7 close to the glass body 4. A brush portion is provided on the side of the rotating nozzles 7 close to the glass body 4. The liquid in the liquid storage chamber 52 flows through the water pipes 6 and then flows to the glass body 4 from the water outlet holes. When the lifting frame 5 is lifted or lowered, the rotating nozzles 7 are rotated by the transmission mechanism to clean the glass body 4. The sewage after cleaning is discharged through the sewage discharge assembly.

[0037] refer to Figure 6-Figure 8 The transmission mechanism includes a synchronous wheel 81, a pulley assembly 82, a synchronous belt 83, a synchronous wheel 84, a gear 3 85 and a rack 86. The rotating nozzle 7 is fixedly connected with a synchronous wheel 81. Each row of synchronous wheels 81 is arranged in pairs. Each pair of synchronous wheels 81 is transmitted through the pulley assembly 82. The middle two synchronous wheels 81 of two adjacent pairs of synchronous wheels 81 are transmitted through the synchronous belt 83. The end of the lifting frame 5 close to the side column 1 is rotatably connected with the synchronous wheel 2 84. The synchronous wheel 2 84 and the adjacent synchronous wheel 1 81 are also transmitted through the synchronous belt 83. The synchronous wheel 2 84 is fixedly connected with the gear 3 85. Two racks 86 are welded on the sides of the two side columns 1 close to each other. The racks 86 are respectively meshed with the gear 3 85. When the gear 3 85 is lifted or lowered, the gear 3 85 rotates under the action of the rack 86.

[0038] refer to Figure 2 , Figure 3 , Figure 4 , Fig. 9 and Fig.10The sewage discharge assembly includes a lifting block 92 and a sewage discharge pipe 94. A sewage discharge hole 91 is opened at the lower part of one end of the lifting frame 5 close to the central column 2. The lifting frame 5 is slidably connected with a lifting block 92 for blocking the sewage discharge hole 91. The lifting block 92 is reset by a compression spring. The lifting block 92 extends from the bottom of the lifting frame 5. The lifting block 92 is provided with a through hole 93 leading to the bottom of the lifting block 92. The through hole 93 is blocked by the lifting frame 5. A sewage discharge pipe 94 is symmetrically fixedly connected to the middle part of the lower horizontal frame 3. The upper end of the sewage discharge pipe 94 is provided with two water inlet ends 95 respectively aligned with the lifting block 92 in the longitudinal direction. The lifting block 92 descends to cover the water inlet end 95, and the lower end of the sewage discharge pipe 94 extends from the front side of the lower horizontal frame 3.

[0039] refer to Figure 2 and Fig.11 The driving assembly includes a screw rod 31, a gear 1 32 and a gear 2 33. Four screw rods 31 are rotatably connected in the middle column 2. The four lifting frames 5 are respectively threadedly connected to the four screw rods 31. Gear 1 32 is welded on the top of the screw rod 31. A driving motor is bolted in the upper horizontal frame 3. Gear 2 33 is fixedly connected to the output shaft of the driving motor. Gear 1 32 is meshed with gear 2 33.

[0040] First, the cleaning liquid for cleaning the glass curtain wall is introduced into the liquid storage chamber 52 through the water inlet hole 51, and the driving motor is controlled to drive the gear 2 33 to rotate, and the gear 2 33 drives the four gears 1 32 to rotate synchronously, and the screw 31 rotates together with the gear 1 32. The screw 31 descends the lifting frame 5 through the threaded connection, and the water pipe 6, the rotating nozzle 7, the synchronous wheel 1 81, the synchronous wheel 2 84, the gear 3 85 and the lifting block 92 descend together with the lifting frame 5. Since the gear 3 85 is meshed with the rack 86, the gear 3 85 rotates while descending, and the gear 3 85 drives the synchronous wheel 2 84 to rotate. The synchronous wheel 2 84 drives all the synchronous wheels 1 81 in turn through the transmission of the synchronous belt 83 and the pulley assembly 82, and the synchronous wheel 1 81 drives the rotating nozzle 7 to rotate. At the same time, the cleaning liquid in the liquid storage chamber 52 flows into the water pipe 6 under the action of gravity, and the cleaning liquid flows from the water outlet of the rotating nozzle 7 to the surface of the glass body 4. The rotating nozzle 7 cleans the surface of the glass body 4 through the bristle part, thereby cleaning the glass. The dirt on the surface of the glass body 4 is brushed off. Since the side of the lifting frame 5 in contact with the glass body 4 is made of rubber, the lifting frame 5 will not wear the surface of the glass body 4, and the lifting block 92 blocks the drainage hole 91, so that the sewage generated by cleaning can be temporarily retained between the lifting frame 5 and the glass body 4. When the descending lifting block 92 covers the water inlet end 95, the lifting block 92 stops moving downward, and the lifting frame 5, the water pipe 6, the rotating nozzle 7, the synchronous wheel 1 81, the synchronous wheel 2 84 and the gear 3 85 continue to move downward, the lifting frame 5 descends to contact the horizontal frame 3 on the lower side, the compression spring is compressed, the lifting block 92 rises relative to the lifting frame 5, the through hole 93 is no longer blocked by the lifting frame 5, and the sewage between the lifting frame 5 and the glass body 4 flows into the drainage pipe 94 through the through hole 93, and then the sewage is discharged through the drainage pipe 94 in a centralized manner, so that the sewage will not flow downward and pollute other glass bodies 4. In this way, the glass curtain wall has an automatic cleaning function and can clean the inner and outer sides of the glass curtain wall at the same time, with good cleaning effect and high cleaning efficiency.

[0041] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 , Fig.12 and Fig.13, also includes a liquid adding mechanism, the liquid adding mechanism includes a liquid adding pipe 101, a mixing box 102, a water tank 103, a water pump 104, a cleaning agent tank 105, a water inlet pipe 106 and a one-way valve 107, the inside of the side column 1 is fixedly connected with the liquid adding pipe 101, the upper end of the liquid adding pipe 101 is provided with two liquid adding ends, and the liquid adding ends can be detachably inserted into the water inlet hole 51, and the lower side of the side column 1 is fixedly connected with the mixing box 102, the top of the mixing box 102 is connected to the lower end of the liquid adding pipe 101 on the same side, and the lower end of the liquid adding pipe 101 is installed A water pump 104 is installed, the bottom of the mixing box 102 is connected to the water tank 103, and a number of one-way valves 107 are installed at the connecting position between the bottom of the mixing box 102 and the water tank 103, the front side of the water tank 103 is connected to a water inlet pipe 106 extending from the front side of the side column 1, and the lower front side of the side column 1 is fixedly connected to a cleaning agent tank 105, the cleaning agent tank 105 is located higher than the mixing box 102, the bottom of the cleaning agent tank 105 and the top of the mixing box 102 are connected by pipes, and solenoid valves are installed on the water inlet pipe 106 and the pipe.

[0042] Before cleaning the glass curtain wall, add the cleaning agent into the cleaning agent tank 105, connect the water inlet pipe 106 to an external water source, control the solenoid valve on the water inlet pipe 106 to open, so that water enters the water tank 103, and the water in the water tank 103 enters the mixing box 102 through the one-way valve 107, and control the solenoid valve on the pipeline to open, so that the cleaning agent in the cleaning agent tank 105 is added to the mixing box 102 filled with water, and the mixing box 102 is filled with a cleaning liquid formed by a mixture of cleaning agent and water, and then the mixing box 102 is pumped by the water pump 104. The internal cleaning liquid is drawn into the liquid adding pipe 101, and the cleaning liquid then flows into the liquid storage chamber 52 through the water inlet hole 51, thereby automatically adding liquid to the liquid storage chamber 52, and the flow rate of water and cleaning agent is adjusted by the solenoid valve, so as to adjust the concentration of the cleaning liquid in the mixing box 102. When it is necessary to use clean water to clean the glass body 4, the solenoid valve on the control pipeline is closed, and water is only added to the mixing box 102 through the water tank 103, so that the rotating nozzle 7 can spray clean water to clean the glass body 4. In this way, the cleaning method is convenient to control.

The L-shaped baffle 112 and the push block 113 are reset by a reset spring. After the L-shaped baffle 112 is opened, the power assembly rotates the gear three 85 and the rotating nozzle 7. The side of the push block 113 close to the water tank 103 is a curved surface. When the push block 113 descends and pushes the L-shaped baffle 112 to open, the push block 113 rises again and is squeezed by the side column 1, and the push block 113 can be retracted again through the curved surface.

Two gear four 122 are welded on the rotating rod 121. When the gear three 85 descends, it will mesh with the gear four 122 respectively, thereby providing power to the gear three 85 through the servo motor.

[0045] Initially, since the push block 113 is squeezed by the side column 1, the return spring on the push block 113 is in a compressed state, and the push block 113 is in a retracted state. When the lifting frame 5 descends, the push block 113 will also descend with the lifting frame 5. When the push block 113 descends to a position aligned with the interval between the L-shaped baffle 112 and the water tank 103, the return spring recovers and drives the push block 113 to extend into the interval, and the lifting frame 5 and the push block 113 continue to descend. The push block 113 pushes the L-shaped baffle 112 to move downward and open, so that the water in the water tank 103 rushes into the space between the lifting frame 5 and the glass body 4 through the opening 110. When the L-shaped baffle 112 is fully opened, the L-shaped baffle 112 is opened as shown in FIG. Fig.15 As shown, gear three 85 is meshed with gear four 122, controlling the servo motor to drive the rotating rod 121 to rotate, driving gear four 122 to rotate, and gear four 122 drives gear three 85 to rotate.
