[0020] When the building needs to be assembled, the assembly base plate 1 can be fixed to the specified position on the ground by means of ground fixing screws, and then the limiting columns 7 arranged at the lower ends of the front and rear side panels 2 are made to fit tightly with the assembly base plate 1. At this time, the plate-like structure arranged at the lower ends of the front and rear side panels 2 passes through the assembly screws at the upper end of the assembly base plate 1, and then the assembly nuts are screwed on. At this time, the front and rear side panels 2 can be fixed to the assembly base plate 1, and then the grooves opened on the left and right side panels 4 are made to fit with the limiting plates 3. Then the left and right side panels 4 are pushed to move the left and right side panels 4 in the direction close to the assembly base plate 1, until the limiting columns 7 arranged at the lower ends of the left and right side panels 4 are made to fit tightly with the assembly base plate 1, and then the fastening screws 5 are turned to tighten. Under the action of the fastening screws 5, the front and rear side panels 2 and the left and right side panels 4 can be fixed in pairs (the number of fastening screws 5 and assembly screws can be increased or decreased according to actual conditions), and then the assembly top plate 6 is moved in the direction close to the front and rear side panels 2 and the left and right side panels 4 until the limit columns 7 set at the upper ends of the front and rear side panels 2 and the left and right side panels 4 are tightly fitted with the assembly top plate 6, and then the assembly top plate 6 can be fixed to the front and rear side panels 2 and the left and right side panels 4 by assembling screws and assembling nuts. At this time, the building can be assembled, and then the gaps between the assembly bottom plate 1, the front and rear side panels 2, the left and right side panels 4 and the assembly top plate 6 are filled by filling structures such as foam glue.

[0021] An additional plate 32 is fixedly installed on the outer surface of the left and right side panels 4, and an assembly hoop 33 is fitted on the additional plate 32, and the assembly hoop 33 is tightly fitted with the outer surface of the water tank 25. A limiting rod 34 is penetrated through the additional plate 32, and the limiting rod 34 and the assembly hoop 33 form a snap-fit ​​connection, an extension plate 36 is fixedly installed on the upper end of the limiting rod 34, and a first spring 35 is fixedly installed on the lower end of the extension plate 36, the first spring 35 and the additional plate 32 are connected to each other, a limiting plate 37 is fixedly installed on the lower end of the extension plate 36, and a second spring 38 is fixedly installed on the lower surface of the extension plate 36, and the second spring 38 is fixedly installed on the additional plate 32, a reinforcing card plate 39 is fixedly installed on the assembly hoop 33, and the reinforcing card plate 39 is tightly fitted with the limiting plate 37, and a water outlet pipe 31 is penetrated through the side of the water tank 25, and the water outlet pipe 31 is tightly fitted in the pipe groove opened on the left and right side panels 4.

[0022] When the water tank 25 needs to be assembled and fixed, the water tank 25 is placed at a designated position on the side of the house, so that the water outlet pipe 31 fixedly installed on the water tank 25 passes through the pipe grooves opened on the left and right side panels 4, and then the extension plate 36 is pulled. Since the lower end of the extension plate 36 is equipped with a limiting rod 34 and a limiting plate 37, the limiting rod 34 and the limiting plate 37 begin to move upward at this time, and the lower end of the extension plate 36 is fixedly equipped with a first spring 35 and a second spring 38. At this time, the first spring 35 and the second spring 38 begin to be stretched and deformed, and then the assembly hoop 33 is fitted with the water tank 25. At this time, the assembly hoop 33 begins to fit with the installation plate 32, and then the assembly hoop 33 is loosened. Open the extension plate 36, and under the action of the first spring 35 and the second spring 38 restoring the deformation, the extension plate 36 begins to be pulled, and the limiting rod 34 and the limiting plate 37 begin to move downward until the limiting rod 34 is tightly fitted with the assembly hoop 33, and the limiting plate 37 is tightly fitted with the reinforcing card plate 39. At this time, the installation plate 32 and the assembly hoop 33 can be assembled and clamped to prevent the water tank 25 from moving in windy weather (to improve stability, the water tank 25 and the assembly hoop 33 can be glued and fixed, and the specific connection method can be limited according to actual conditions). By setting the water tank 25 on the side of the building, the impact of stored water on the building can be reduced.

[0023] A roof panel 8 is fixedly installed on the upper end of the assembled top plate 6, a water collecting plate 9 is fixedly installed on the upper end of the roof panel 8, a first motor 10 is fixedly installed on the rear side of the water collecting plate 9, an output end of the first motor 10 is connected to a rotating screw 12, a first pulley 11 is fixedly installed on the rear side of the rotating screw 12, a second pulley 13 is fixedly installed on the front side of the rotating screw 12, a cleaning plate 14 is arranged on the rotating screw 12, a first cleaning brush 15 is fixedly installed on the lower end of the cleaning plate 14, a second cleaning brush 17 is installed on the side of the cleaning plate 14, a photovoltaic panel 16 is fixedly installed on the upper end of the roof panel 8, a filter plate 18 is fixedly installed on the upper surface of the roof panel 8, and the filter plate 18 is connected to the water collecting plate 9, and a water inlet pipe 24 is provided on both sides of the roof panel 8. A water storage tank 25 is fixedly installed at the lower end of the water inlet pipe 24, and densely penetrated filtering holes are provided on the filter plate 18, and the filter plate 18 is arranged as an inclined plate-like structure. A protective plate 19 is fixedly installed on the upper surface of the filter plate 18, and the protective plate 19 is connected with the water collecting plate 9, and a fixed plate 23 is fixedly installed on the water collecting plate 9, and a fixed sleeve 22 is fixedly installed on the fixed plate 23, and a vortex spring 21 is fixedly installed inside the fixed sleeve 22, and a first bearing is arranged on the fixed plate 23. The unloading plate 20 is composed of a plate-like structure and a rotating shaft on the side, and the rotating shaft forms a rotating mechanism with the fixed plate 23 through the first bearing installed on the fixed plate 23, and the outer surface of the rotating shaft is connected with the vortex spring 21, the unloading plate 20 is tightly fitted with the water collecting plate 9, and a through sewage discharge groove is provided on the water collecting plate 9.

[0024] The rainwater is guided through the water collecting plate 9, and then filtered through the dense holes opened on the filter plate 18. The filtered water enters the water storage tank 25 through the water inlet pipe 24 for storage. When it is necessary to clean the roof 8 and the upper surface of the photovoltaic panel 16, the first motor 10 starts to work. Because the output end of the first motor 10 is connected to the rotating screw 12, the four rotating screws 12 can be rotated at the same time under the action of the first pulley 11 and the second pulley 13. Because the rotating screw 12 is connected to the cleaning plate 14 through the threaded holes opened on the cleaning plate 14, the cleaning plate 14 starts to move as the rotating screw 12 rotates. Because the first cleaning brush 15 is installed at the lower end of the cleaning plate 14, and the second cleaning brush 17 is installed on the side, at this time, the first cleaning brush 15 is used to clean the cleaning plate 14. The first cleaning brush 15 and the second cleaning brush 17 can be used to brush and clean the roof 8, the photovoltaic panel 16 and the filter plate 18 (the length and density of the bristles of the first cleaning brush 15 and the second cleaning brush 17 can be adjusted according to actual conditions). As impurities such as leaves and dust are brushed and cleaned, the impurities such as leaves and dust are pushed to the rear end of the water collecting plate 9. At this time, the impurities such as leaves and dust begin to contact the discharge plate 20 and push the discharge plate 20, that is, the discharge plate 20 begins to rotate around the fixed plate 23. At this time, the vortex spring 21 begins to be squeezed and deformed, so that impurities such as leaves and dust can be discharged. After discharge, as the vortex spring 21 recovers its deformation, the discharge plate 20 begins to move toward the water collecting plate 9, thereby preventing impurities such as leaves and dust from affecting the flow rate of rainwater and affecting the working effect of the photovoltaic panel 16.

[0025] A sliding plate 26 is slidably provided on the outside of the water inlet pipe 24, and a second motor 27 is fixedly provided on the sliding plate 26. A driving screw 28 is fixedly installed on the output end of the second motor 27. A second bearing is provided on the sliding plate 26, and the driving screw 28 forms a rotating mechanism with the sliding plate 26 through the second bearing installed on the sliding plate 26. A threaded hole and a through-chute are provided on the upper end of the water storage tank 25, and the driving screw 28 is connected to the water storage tank 25 through the threaded hole provided on the water storage tank 25. A lifting plate 29 is slidably provided inside the water storage tank 25, and a third bearing is provided on the left side of the upper surface of the lifting plate 29, and the driving screw 28 forms a rotating mechanism with the lifting plate 29 through the third bearing installed on the lifting plate 29. A limiting guide rod 30 is fixedly installed on the right side of the upper surface of the lifting plate 29, and the limiting guide rod 30 forms a sliding connection with the water storage tank 25 through the through-chute provided on the water storage tank 25, and the limiting guide rod 30 is fixedly installed on the lower surface of the sliding plate 26.

[0026] The filtered rainwater enters the water tank 25 through the water inlet pipe 24 and is stored at the upper end of the lifting plate 29 (the lifting plate 29 can slide inside the water tank 25, but because the lifting plate 29 fits the water tank 25 relatively tightly, water can be prevented from entering the lower end of the lifting plate 29). Then the second motor 27 starts to work. Because the output end of the second motor 27 is connected to the driving screw 28, the driving screw 28 starts to rotate at this time. Because the driving screw 28 is connected to the water tank 25 through the threaded hole opened on the water tank 25, as the driving screw 28 rotates, the lifting plate 29 starts to rise slowly under the action of the limiting guide rod 30, thereby achieving the purpose of lifting the rainwater. After that, the rainwater can be introduced into the building for use through the outlet pipe 31. By setting the outlet pipe 31 at the upper end, the mud and sand settled at the bottom can be effectively prevented from being introduced, thereby ensuring the quality of the rainwater.
