[0026] The wall cleaning device includes a drainage riser 101 connected to the water blowing port 5, a horizontal pipe 102, a cylindrical roller brush 103, a frame 104, a tension spring 105, a water hose 106 and a coil spring 107. Two parallel horizontal pipes 102 are respectively connected to the side walls of the drainage riser 101; the frame 104 includes a sliding frame 141 that slides with the horizontal pipe 102, and the inner wall of the sliding frame is provided with a rotating shaft 142 for inserting the two ends of the roller brush 103, and a connecting rod 143 is provided between the side walls of the sliding frame 141 at both ends; one end of the two tension springs 105 is respectively connected to the upper and lower sides of the side walls of the connecting rod 143, and the other end is connected to the drainage riser. 101 is connected; the coil spring 107 is a metal strip curled into a spiral structure, the outer end of which is connected to the side wall of the drainage riser 101, and the inner end is a circular ring structure; one side surface of the water hose 106 is fixedly connected to the coil spring 107, the closed end of which is connected to the inner end surface of the coil spring 107, and the open end of which is connected to the outer end surface of the coil spring 107; two fixing rods 144 are provided above and below the side wall of the connecting rod 143, and the inner wall of the fixing rod 144 is provided with a second rotating shaft 145 for fitting on the inner end of the coil spring 107; the surface of the horizontal tube 102 is provided with a plurality of water spray outlets 121 at intervals, and the water hose is a tubular belt fabric that can withstand a certain liquid pressure. It can deliver water or foam fire extinguishing liquid at a relatively high pressure; it can greatly improve the cleaning efficiency of the wall surface and can greatly reduce the work intensity of the user. Water flows through the drainage vertical pipe 1, and the horizontal pipe 2 is connected thereto. The water can be sprayed out through the water spray port 21, so that the roller brush 3 can automatically get wet during the wall brushing process, and the wall surface can also be flushed with water, thereby improving its washing efficiency;

[0027] The working process of the wall cleaning device is as follows: when cleaning the exterior wall of a building, firstly, the roller brush 103 dipped in cleaning liquid is installed on the rotating shaft 142 of the frame 104, then the sliding frame 141 is mounted on the horizontal pipe 102 from the front end thereof, and then the inner end of the coil spring 107 is mounted on the outside of the second rotating shaft 145, and finally, the two ends of the tension spring 105 are respectively connected to the drainage riser 101 and the connecting rod 143; the open end of the water hose 106 is connected to the external water injection device to provide or reduce the water pressure for injecting and releasing water from the water hose 106. When the water hose 106 is injected with water, the water hose 106 is straightened and expanded. The roller brush 103 expands and pushes the roller brush 103 forward against the elastic force of the tension spring 105 and the coil spring 107, so that the roller brush 103 moves left and right on the track, thereby making the roller brush 103 brush the wall surface for scrubbing. When the water hose 106 is released, that is, its internal pressure is reduced, the water hose 106 moves toward the direction of the drainage riser 101 under the restoring effect of the tension spring 105. At the same time, due to the restoring effect of the coil spring 107, it automatically coils around the inner end of the coil spring 107 as the axis. When the scrubbing work is completed, the tension spring 105 is removed and the roller brush 103 can be directly taken out from the front end of the horizontal pipe 102.

[0028] An overflow port 10 is provided above the front wall of the first cavity 6. The height of the overflow port 10 is higher than the highest point of the first baffle 2. By setting the overflow port 10, excess rainwater in the rainwater storage tank overflows to the domestic non-drinking water supply pipe.

[0029] The bottoms of the first cavity 6 , the second cavity 7 and the third cavity 8 are all provided with venting ports 11 .

[0030] The drain port 11 at the bottom of the second cavity 7 is provided with a magnetic control valve, which is used to automatically open the drain port 11 at the bottom of the second cavity 7 when the water level in the second cavity 7 is high.

[0031] Water outlets 5 are provided below the front and rear side walls of the third cavity 8 , and a water main pipe 12 for connecting to the drainage riser 101 is provided on the water outlet 5 above the front side wall.

[0032] The filter layer 9 is provided with activated carbon, geotextile, quartz sand, ceramsite and sponge to remove suspended particles, reduce COD, TSS and chromaticity, etc.

[0033] The fixing rod 144 is arranged parallel to the transverse tube 102 to ensure that the roller brush 103 moves along the direction thereof.

[0034] The surface of the roller brush 103 is in close contact with the wall surface to be cleaned; a gap is provided between the frame 104 and the wall surface to be cleaned, so as to ensure that the frame 104 does not rub or collide with the wall surface to avoid damaging the wall surface.

[0035] Embodiment of rainwater collection device: Several rainwater storage tanks corresponding to the roof drainage area are set on the roof of the building. The volume and number of the water tanks are determined according to the actual amount of rainwater required. The specific location of the water tank is comprehensively considered in combination with the structural layout and pipeline distribution of the building. This embodiment takes a building with a length of 50m, a width of 10m, a floor height of 3m and a total of 10 floors as an example to design the water tank. The water volume is estimated to obtain the following structure and size of the water tank:

[0036] The water tank 1 is composed of an external box body with a rainwater collection port 4 and a water outlet 5 and two internal first baffles 2 and second baffles 3. The length, width and height of the inner cavity of the box body 1 are 1400mm, 1000mm and 1200mm respectively, and the thickness of the box body wall and the first and second baffles are 20mm. The first baffle 2 is a hard plastic plate with a height of 1000mm. The second baffle 3 has a total height of 1200mm, which is divided into an upper 1100mm high hard plastic plate and a lower 100mm high and 100mm thick filter layer 9. The filter layer 9 contains activated carbon, geotextile, quartz sand, ceramsite and sponge and other filter media to remove suspended particles, reduce COD, TSS and chromaticity, etc. The first and second baffles divide the inner cavity of the box body 1 into the first, second and third cavities, with lengths of 360mm, 460mm and 460mm respectively, and their functions are precipitation, filtration and disinfection respectively. The third cavity 8 is manually placed with a certain proportion of sodium hypochlorite solution during rain collection for disinfection. Three drain ports 11 are set at the bottom of the box 1. The drain port 11 at the bottom of the second cavity 7 is set with a magnetic control valve. When the water level in the box 1 is high, the drain port 11 at the bottom of the second cavity 7 automatically opens, and a part of the rainwater in the third cavity 8 will flow back into the second cavity 7 to backwash the filter layer 9 in the box 1. After the water level in the box 1 is reduced, the water pressure decreases, and the magnetic control valve in the second cavity 7 is closed. The other two drain ports 11 are used to discharge rainwater in the water tank when cleaning the water tank. The drain port 11 is connected to the municipal sewage and wastewater drainage pipeline. There are two water delivery mains 12 at the bottom of the third cavity 8. The front water delivery main is connected to the drainage riser 101 of the building's outer wall and is set with a valve for cleaning the outer wall at a specific time. The rear water delivery main is set with a one-way valve and connected to the non-drinking water supply pipeline.
