[0028] Please also read Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , the rainwater collection and filtration device provided by the utility model is now described. The rainwater collection and filtration device comprises a collection tank 1, a storage box 2, a partition 3, an isolation net 4, a support 5, a filter net 6, a pipeline assembly 7, a water outlet pipe 8 and a valve 9. The notch of the collection tank 1 is upward and fixed on the wall of the building. The storage box 2 is located below the collection tank 1 and is used to be placed on the ground. The partition 3 is located in the storage box 2, and the partition 3 is fixedly connected to the storage box 2 to separate the storage box 2 into a filter chamber 201 and a collection chamber 202. The collection chamber 202 is located below the filter chamber 201. The partition 3 is provided with a plurality of leakage holes 31 for connecting the filter chamber 201 and the collection chamber 202. The isolation net 4 is fixedly attached to the upper surface of the partition 3, and the isolation net 4 covers all the leakage holes 31. The support 5 is slidably penetrated in the filter chamber 201 along the vertical direction, and the support 5 is provided with a plurality of liquid inlet holes 51, and the hole depth direction of the liquid inlet holes 51 is vertically arranged. The filter screen 6 is fixedly attached to the lower surface of the support member 5, and the filter screen 6 covers all the liquid inlet holes 51. The space between the filter screen 6 and the isolation net 4 is used to fill the activated carbon particles 170. The pipeline assembly 7 is used to connect the collection tank 1 and the filter chamber 201. One end of the water outlet pipe 8 is fixedly connected to the storage box 2 and communicated with the bottom of the collection chamber 202. The valve 9 is arranged at the other end of the water outlet pipe 8.

[0029] Compared with the prior art, the rainwater collection and filtration device provided by the utility model can prevent the activated carbon particles 170 from entering the collection chamber 202 through the leakage hole 31. The rainwater collected by the collection tank 1 enters the filter chamber 201 through the pipeline assembly 7, then falls through the liquid inlet hole 51, and then passes through the double filtration and purification of the filter net 6 and the activated carbon particles 170, and finally enters the collection chamber 202 through the isolation net 4 and the leakage hole 31, thereby avoiding the problem of poor effect of filtering and purifying rainwater through the filter net 6 alone.

[0030] In this embodiment, the valve 9 is opened, and the collected and filtered rainwater in the collection chamber 202 flows out from the outlet pipe 8, and then can be used. The filter screen 6 is located above the isolation net 4, and both the filter screen 6 and the isolation net 4 can be made of gauze. The rainwater can directly fall into the collection tank 1, and the collection tank 1 can also receive rainwater flowing down from the building. The support member 5 can support the filter screen 6 to prevent the filter screen 6 from rolling up.

[0031] In some embodiments, the above-mentioned characteristic storage box 2 can be used as follows Figure 1 and Figure 2 See the structure shown. Figure 1 and Figure 2 The storage box 2 is divided into a box body 21 and a cover plate 22. The upper end of the box body 21 is an open end. The cover plate 22 is horizontally arranged and located on the box body 21 to cover the upper end of the box body 21. When the cover plate 22 opens the upper end of the box body 21, the impurities left on the filter screen 6 after filtering rainwater can be cleaned. When the support member 5 drives the filter screen 6 to slide out of the filter chamber 201, the activated carbon particles 170 that have been used for a period of time can be replaced.

[0032] In some embodiments, the above-mentioned characteristic pipeline assembly 7 can be used as follows Figure 1 See the structure shown. Figure 1 The pipeline assembly 7 includes a downpipe 71 and a sleeve 72. The downpipe 71 is vertically arranged, and is located between the collecting tank 1 and the cover plate 22. The downpipe 71 is fixedly connected to the collecting tank 1 and communicates with the inside of the collecting tank 1. The sleeve 72 is slidably sleeved outside the downpipe 71, and is fixedly connected to the cover plate 22 and communicates with the filter chamber 201. The rainwater collected in the collecting tank 1 flows into the filter chamber 201 through the downpipe 71 and the sleeve 72. When the sleeve 72 slides upward, it can drive the cover plate 22 to move upward to open the upper end of the box body 21.

[0033] In some embodiments, see Figure 2 and Figure 5The rainwater collection and filtration device also includes a fixing member 10, a fixing shaft 110 and a lifting shaft 120. The fixing member 10 is provided with a threaded hole, and the depth direction of the threaded hole is vertically arranged. There is at least one fixing shaft 110, and the two ends of the fixing shaft 110 are fixedly connected to the fixing member 10 and the collecting tank 1 respectively. The lifting shaft 120 is passed through the threaded hole and is provided with an external thread threadedly connected to the threaded hole, and the lifting shaft 120 is rotatably connected to the cover plate 22. The fixing member 10 is fixedly connected to the collecting tank 1 through the fixing shaft 110. The lifting shaft 120 is driven to rotate, and the lifting shaft 120 threadedly connected to the threaded hole can move in the vertical direction. When the lifting shaft 120 moves upward, it can drive the cover plate 22 to move upward; when the lifting shaft 120 moves downward, it can make the cover plate 22 press against the box body 21.

[0034] In some embodiments, the above-mentioned characteristic lifting shaft 120 can be used as follows Figure 2 and Figure 4 See the structure shown. Figure 2 and Figure 4 The lifting shaft 120 can rotate and penetrate the cover plate 22. The side wall of the lifting shaft 120 has two outwardly protruding limit parts 1201, and the two limit parts 1201 are respectively in contact with the top surface and the bottom surface of the cover plate 22. The two limit parts 1201 can limit the relative movement of the cover plate 22 and the lifting shaft 120 in the vertical direction, so as to rotatably connect the lifting shaft 120 and the cover plate 22 together.

[0035] In some embodiments, see Figure 4 The rainwater collection and filtering device further comprises a driving shaft 130. The driving shaft 130 is perpendicular to the lifting shaft 120 and the middle portion thereof is fixed in the lifting shaft 120. It is convenient to drive the lifting shaft 120 to rotate by the driving shaft 130.

[0036] In some embodiments, see Figure 2 and Figure 6 The rainwater collection and filtering device further includes two U-shaped handles 140. The two U-shaped handles 140 are located in the filter chamber 201, and the U-shaped handles 140 are fixed on the support member 5. When the cover plate 22 opens the upper end of the box body 21, the two U-shaped handles 140 can be used to drive the support member 5 to slide upward and exit the filter chamber 201.

[0037] In some embodiments, see Figure 1 and Figure 2 The rainwater collection and filtering device further comprises a steel mesh 150. The steel mesh 150 is located in the collection tank 1, and the steel mesh 150 is circumferentially fixedly connected to the inner side surface of the collection tank 1. The steel mesh 150 can prevent larger impurities such as fallen leaves from entering the pipeline assembly 7, thereby reducing the probability of the pipeline assembly 7 being blocked.

[0038] In some embodiments, see Figure 1The number of the pipeline components 7 is at least two, so that the rainwater in the collection tank 1 can quickly flow into the filter chamber 201.

[0039] In some embodiments, see Figure 1 The bottom of the storage box 2 is fixedly provided with a plurality of legs 160 for supporting the storage box 2. The storage box 2 is placed on the ground through the legs 160, so that the water outlet pipe 8 on the storage box 2 can be located at a suitable height.
