[0010] Preferably, a receiving base is opened inside the collecting pile. The clamping plate is inserted into the receiving base. A hole is arranged at the center of the collecting pile and is communicated with the water collecting pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] A kind of urban rainwater filtration and collection device of the utility model preliminarily blocks the leaves and sundries mixed in the rainwater through the filter screen in the filter frame, preventing the leaves and sundries from entering the water collecting pipe and causing blockage. And when there are too many leaves and sundries attached to the filter screen, the filter frame is taken out of the collecting pile for cleaning and reused.

[0013] The rainwater carrying sediment enters the water collecting frame for sedimentation and separation. The clear rainwater passes through the drain pipe after passing over the blocking plate for collection, and the precipitated sediment is concentrated and flushed out from the silt pipe.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, An urban rainwater filtration and collection device, including a collection pile 1, a water collection pipe 3, a water collection frame 4, and a drain pipe 7. The road surface around the collection pile 1 is recessed towards the collection pile 1 to facilitate the guidance of rainwater. The bottom of the collection pile 1 is connected to the water collection pipe 3. One end of the water collection pipe 3 away from the collection pile 1 is inserted into the water collection frame 4. The rainwater is collected by the water collection pipe 3 and then transported into the water collection frame 4. One side of the water collection frame 4 is connected to the drain pipe 7. A filter frame 2 is provided inside the collection pile 1, and a blocking plate 5 is provided inside the water collection frame 4. A sloping baffle 51 is fixedly connected to the side of the blocking plate 5 close to the water collection pipe 3. The rainwater falls into the water collection frame 4 under the guidance of the sloping baffle 51, and the sediment in the rainwater is precipitated. After the clear rainwater passes over the blocking plate 5, it is centrally discharged and collected from the drain pipe 7. A silt pipe 6 is opened on the water collection frame 4 below the sloping baffle 51. Electronic valves are provided in both the silt pipe 6 and the drain pipe 7 to control the opening and closing of the silt pipe 6 and the drain pipe 7. After opening the pipeline of the silt pipe 6 through the electronic valve, the sediment is flushed and discharged. A water storage frame 21 is provided at the front end of the filter frame 2. Filter meshes 22 are opened at the bottom and on the side of the water storage frame 21 close to the filter frame 2. The filter meshes 22 filter the leaves and sundries in the rainwater.

[0020] Further, a maintenance window is opened at the top of the water collection frame 4. A flip plate 41 is provided in the maintenance window. The flip plate 41 is movably connected to the water collection frame 4. When necessary, the water collection frame 4 is dredged and repaired through the maintenance window.

[0021] Further, both the silt pipe 6 and the drain pipe 7 are located at the bottom of the water collection frame 4, which is convenient for the rainwater in the water collection frame 4 to be discharged.

[0022] Further, a clamping plate 23 is fixedly connected to the bottom end of the filter frame 2. A clamping groove is provided between the two clamping plates 23. The filter frame 2 is installed in the collection pile 1 through the clamping groove.

[0023] Further, a receiving base is opened inside the collection pile 1. The clamping plate 23 is inserted into the receiving base. After the sundries on the filter meshes 22 are too much, the leaves and sundries on the filter meshes 22 are cleaned and reinstalled into the collection pile 1. A hole is provided at the center of the collection pile 1 and is interconnected with the water collection pipe 3.

[0024] Working principle: For a kind of urban rainwater filtering and collecting device of the utility model, during use, rainwater flows into the collecting pile 1. The leaves and sundries mixed in the rainwater are blocked by the filter net 22. After there is too much sundries on the filter net 22, the leaves and sundries on the filter net 22 are cleaned and reinstalled into the collecting pile 1. The remaining rainwater enters the water collecting frame 4 through the water collecting pipe 3. The rainwater falls into the water collecting frame 4 under the guidance of the inclined baffle 51, and the sediment in the rainwater is precipitated. The remaining clear rainwater is discharged and collected centrally from the drain pipe 7 after passing over the blocking plate 5. When there is too much sediment precipitated under the inclined baffle 51, after opening the pipeline of the silt pipe 6 through the electronic valve, the sediment is flushed and discharged.
