The water conveying pipes 20 are connected with an external water supply and drainage system, so as to input the filtered rainwater from the rainwater collection, filtration and infiltration devices 10 into the external water supply and drainage system for use, such as irrigation, car washing, landscape water replenishment and the like, so as to realize the collection and use of rainwater. According to the actual use environment and use scene, different numbers of rainwater collection, filtration and infiltration devices 10 can be selected for assembly to meet different use requirements and improve the application range.

[0035] Please refer to Figure 2 and Figure 3The utility model also provides a rainwater collection filtration infiltration device 10, it includes the box 100 for containing rainwater, the box 100 upper end opening is provided, and the filter grate 110, first water treatment module 120 and second water treatment module 130 are sequentially arranged from top to bottom in the box 100, when rainwater enters the box 100 from the box 100 top opening, the filter grate 110, first water treatment module 120 and second water treatment module 130 carry out step by step filtration to the rainwater of entering the box 100. The bottom of box 100 has the containing cavity 140, and the filtered rainwater enters the containing cavity 140 storage. Further, first water treatment module 120 includes filter plants 121, planting soil layer 122 and first support filter piece 123 sequentially arranged from top to bottom, and first support filter piece 123 filters rainwater, and first support filter piece 123 is also used to support planting soil layer 122. Meanwhile, filter box 30 is also provided between filter grate 110 and first support filter piece 123, filter hole is formed in filter box 30, and filter box 30 is transparently arranged.

[0036] By setting filter grate 110, first water treatment module 120 and second water treatment module 130 in the box 100, rainwater is sequentially infiltrated and filtered, and the filtration effect of rainwater is improved. Meanwhile, first water treatment module 120 includes filter plants 121, and rainwater is filtered through filter plants 121, which can effectively remove nutrients in rainwater, fully exert the natural filtering effect of plants, embody the concept of ecological environmental protection, reduce the dependence on chemical purifying agents, and reduce the risk of secondary pollution. And, by setting filter box 30, light can irradiate filter plants 121 through filter grate 110 and transparently arranged filter box 30, to provide growth conditions for filter plants 121 and ensure the survival of filter plants 121.

[0042] It can be understood that the thickness of the planting soil layer 122 and the filler 131 can be selected according to the actual use scene and the filtering requirement, as long as the thickness of the planting soil layer 122 can meet the requirement that the root system of the filtering plant 121 has a certain growth space.

[0043] Please refer to Figure 2 and Figure 3 In the embodiment, the second support filter 132 comprises a second support plate which is detachably arranged in the box body 100, the second support plate is made of the same material as the first support plate, and filter holes are also arranged on the second support plate. Further, a second filter layer 133 is arranged on the upper surface of the second support plate, and the second filter layer 133 is also made of filtering materials such as needle-punched non-woven fabric and hot-rolled non-woven fabric. It can be understood that, in order to realize multi-stage filtering of rainwater, the filter hole diameter on the second support plate is smaller than the filter hole diameter on the first support plate.

[0044] Please refer to Figure 2 and Figure 3 In order to use the filtered rainwater stored in the containing cavity 140, in some optional embodiments, a water outlet 150 is arranged on the box body 100 and communicates with the containing cavity 140, so as to discharge and use the filtered rainwater in the containing cavity 140. In the rainwater collection, filtering and infiltration system, the water conveying pipe 20 communicates the water outlets 150 of the plurality of rainwater collection, filtering and infiltration devices 10, so as to discharge the filtered rainwater stored in the containing cavities 140 of the plurality of rainwater collection, filtering and infiltration devices 10.

[0045] Please refer to Figure 2 and Figure 3 In order to facilitate detachable connection of the plurality of rainwater collection, filtering and infiltration devices 10, in some optional embodiments, a connecting piece 160 is arranged on the box body 100, and the adjacent box bodies 100 are detachably connected through the connecting piece 160.
