Detailed Implementation

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example 1, such as Figures 2 to 4 As shown, a rainwater drainage structure for building construction includes a foundation 1, a rainwater collection structure on the top of the foundation 1, a filter chamber 2 and a sand storage chamber 3 inside the foundation 1, with the sand storage chamber 3 located to the right of the filter chamber 2, a rainwater coarse filtration structure on the top of the filter chamber 2, and a rainwater fine filtration structure inside the filter chamber 2, with the rainwater fine filtration structure located below the rainwater coarse filtration structure.

[0027] Specifically, the foundation 1 also has a connecting port 5, through which the filter chamber 2 and the sand storage chamber 3 are connected.

[0028] Specifically, the rainwater fine filtration structure includes a fine filter plate 4 installed at an angle inside the filter chamber 2. More specifically, one end of the fine filter plate 4 is fixedly connected to the left inner wall of the filter chamber 2, and the other end is fixedly inserted into the interior of the connecting opening 5. The end of the fine filter plate 4 fixedly connected to the left inner wall of the filter chamber 2 is higher than the end inserted into the interior of the connecting opening 5, that is, the fine filter plate 4 is inclined towards the sand storage chamber 3 so that the sediment trapped on it can slide into the sand storage chamber 3.

[0029] Specifically, the inside of the communication port 5 is rotatably installed with a rotating plate 6 located at the top of the fine filter plate 4, and the inside of the communication port 5 is fixedly installed with a blocking plate 7 close to the top of the communication port 5, and the blocking plate 7 is located at the left side of the rotating plate 6.

[0030] In use, the rainwater on the top of the foundation 1 flows into the inside of the filtering chamber 2 after being filtered by the rainwater coarse filtering structure, and the rainwater flowing into the inside of the filtering chamber 2 is filtered by the fine filter plate 4 and stays at the bottom of the filtering chamber 2. At this time, the sand with a particle size greater than that of the fine filter plate 4 intercepted by the fine filter plate 4 stays at the top of the fine filter plate 4. Since the fine filter plate 4 is inclined to the sand storage chamber 3, the sand at the top of the fine filter plate 4 is washed away by the rainwater. Under the washing action of the rainwater, the sand at the top of the fine filter plate 4 is pushed by the communication port 5 to drive the rotating plate 6 to rotate in the opposite direction, and then slides into the inside of the sand storage chamber 3. In this way, the sand neither accumulates on the top of the fine filter plate 4 nor presses the fine filter plate 4. After the sand slides into the inside of the sand storage chamber 3, the left side of the rotating plate 6 loses the pushing force of the sand and is reset under the action of gravity. After the rotating plate 6 is reset, the blocking plate 7 installed at the right side of the rotating plate 6 limits the rotating plate 6.

[0031] Embodiment 2, as shown in the figure, is a further improvement based on Embodiment 1, which is as follows: Figures 1 to 5

[0032] The rainwater coarse filtering structure includes a bottom frame 8 fixedly installed at the top of the filtering chamber 2. The top of the bottom frame 8 is fixedly installed with a metal fence 9. The top of the metal fence 9 is fixedly installed with a coarse filter screen 10. The top of the coarse filter screen 10 is paved with a sand and gravel layer 11, and the top of the sand and gravel layer 11 is flush with the top of the foundation 1.

[0033] In this way, the bottom of the metal fence 9 is supported by the installed bottom frame 8. The produced rainwater can filter out tree leaves and garbage through the sand and gravel layer 11. The installed coarse filter screen 10 can not only filter out stones in the rainwater, but also prevent the sand and gravel layer 11 from falling into the inside of the filtering chamber 2 through the metal fence 9. Finally, the filtered rainwater flows into the inside of the filtering chamber 2 through the metal fence 9.

[0034] Embodiment 3, as shown in the figure, is a further improvement based on Embodiment 1, which is as follows: Figures 1 to 3

[0035] The rainwater collecting structure includes a water storage cylinder 12 fixedly installed at the top of the foundation 1. The right side of the water storage cylinder 12 is fixedly installed with a water pump 13. The suction end of the water pump 13 is fixedly installed with a water suction pipe 14 penetrating into the inside of the foundation 1 and communicating with the filtering chamber 2. The drainage end of the water pump 13 is fixedly installed with a drainage pipe 15 penetrating into the inside of the water storage cylinder 12.

[0036] ​​In this way, the water pump 13 can draw filtered rainwater at the bottom of the cavity of the filter chamber 2 through the water suction pipe 14, and then discharge the rainwater into the storage cylinder 12 through the drain pipe 15 for storage, and the stored rainwater can be used for secondary use.

[0037] Embodiment 4, as shown in the figure, this embodiment is further improved on the basis of embodiment 1, which is as follows: Figures 1 to 3

[0038] The front and rear inner walls of the sand storage chamber 3 are fixedly installed with groove plates 16 close to the top thereof, and a top cover 17 is movably installed between the two groove plates 16.

[0039] In this way, the top cover 17 is limited at the top of the sand storage chamber 3 by the two groove plates 16, and the installed top cover 17 can prevent foreign matter from falling into the interior of the sand storage chamber 3.

[0040] Embodiment 5, as shown in the figure, this embodiment is further improved on the basis of embodiment 1, which is as follows: Figures 1 to 3

[0041] The top of the top cover 17 is fixedly installed with two handles 18, and the two handles 18 are close to the two groove plates 16, respectively.

[0042] In this way, the two handles 18 are convenient for lifting the top cover 17 upward.

[0043] Embodiment 6, as shown in the figure, this embodiment is further improved on the basis of embodiment 1, which is as follows: Figures 2 to 3

[0044] The inner wall of the sand storage chamber 3 is fixedly installed with a plurality of handrails 19, and the plurality of handrails 19 are vertically arranged in a linear array.

[0045] In this way, the plurality of installed handrails 19 facilitate personnel to enter the interior of the sand storage chamber 3 to clean the sand.

[0046] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and those skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.​​​
