However, in mountainous areas or on slopes, rainwater flows down from ditches at the top of a mountain or slope, and is mixed with various impurities such as leaves and stones in the process. When the rainwater reaches the downstream, it is difficult to separate and treat it. If it is directly separated by a filter net or filter plate and then collected, it is easy for the filter net to be clogged or the impurities at the separation point to be difficult to clean.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0024] like Figures 1 to 3 As shown, this embodiment provides a rainwater collection device, including an inclined diversion structure, a separation structure and a drain pipe 1, wherein the diversion structure is used to collect and divert rainwater, and the diversion structure is connected to a separation pool 2. The separation structure is arranged in the separation pool 2 and is used to separate impurities in the rainwater. The drain pipe 1 is located at the end of the separation pool 2, and one end of the drain pipe 1 is connected to the separation structure and the other end extends out of the separation pool 2. After the impurities in the rainwater are separated by the separation structure, the rainwater is discharged from the separation pool through the drain pipe 1. The drain pipe 1 is inclined and its water inlet end is higher than the water outlet end.
[0025] The diversion structure is a drainage ditch, which includes a first ditch 5 and a second ditch 6. The inlet of the separation pool 2 is connected to the first ditch 5, and the first ditch 5 is connected to the second ditch 6. A gate 7 is provided at the outlet of the second ditch 6. The outlet of the second ditch 5 can be blocked as needed to clean up impurities in the separation pool 2. The second ditch 6 extends to the side slope or the top of the hillside to collect and divert rainwater. The rainwater flows along the second ditch 6 to the first ditch 5, and then flows into the separation pool 2. After the impurities such as branches, dead leaves, and stones are separated from it by the separation structure, it flows out of the separation pool 2 through the drain pipe 1 for subsequent treatment or utilization.
[0026] like Figure 1As shown, the separation structure includes a diverter block 3 and two filter screens 4. A clean water space is formed between the two filter screens 4 and the inner bottom surface of the separation pool 2. The cross-section of the diverter block 3 is triangular, and one tip of the triangle faces the inlet of the separation pool 2. The diverter block 3 is used to divert rainwater entering the separation pool 2 to both sides. The diverted rainwater can contact the filter screens 4 over a larger area to filter and separate impurities therein. The filter screens 4 are fixedly arranged at the rear end of the diverter block 3. The clean water space is connected to the drain pipe 1. The rainwater after separation of impurities enters the clean water space and is discharged through the drain pipe 1.
[0027] The diversion block 3 is conical and its conical tip faces the inlet of the separation pool 2. The upper ends of the two filter screens 4 are fixedly connected, and the lower ends are fixedly connected to the bottom surface of the separation pool 2. The clean water space is a triangular prism structure. The conical diversion block 3 has a better diversion effect, and the filter screen 4 is tilted. The clean water space is a triangular prism structure with a small front end and a large rear end. The contact area between the rainwater containing impurities and the filter screen 4 is increased, and the separation is rapid. Then, the branches, leaves, large stones, etc. in the rainwater remain in the separation pool 2, and the clean rainwater enters the clean water space. At the same time, the separated impurities are washed by the continuously flowing rainwater and collected at the end of the separation pool 1, which is convenient for removal and processing. Under normal circumstances, the impurities can be directly fished out at the end of the separation pool 2. If there are too many impurities, the water flow channel between the second ditch 6 and the first ditch 5 can also be disconnected by the gate 7, and then the separation pool 2 is cleaned.
[0028] During use, rainwater on the slope or hillside flows down through the drainage ditch. In the process of flowing down, some impurities such as dead branches and leaves, dead grass, stones, gravel, etc. will be mixed into it. Then the rainwater mixed with impurities passes through the second ditch 6 and the first ditch 5 in turn into the separation pool. Then, under the action of the diversion block 3, it flows to both sides of the separation pool 2, and then contacts the filter plate 4. Then, the rainwater enters the clean water space through the filter plate 4. The two impurities remain on both sides of the clean water space in the separation pool 2, and under the continuous impact of the water flow, they gather at the end of the separation pool 2. When too many impurities gather, the water flow channel between the second ditch 6 and the first ditch 5 is cut off by the gate 7, and then the impurities in the separation pool 2 can be cleaned.
[0029] like Figure 4 As shown, as an implementable embodiment, the diversion block 3 is in the shape of a triangular prism, the two filter screens 4 are arranged in parallel, and a top plate 8 is fixed on the top, and the clean water space is in the shape of a rectangular parallelepiped. At this time, the filter screen 4 is parallel to the corresponding side wall of the separation pool 2. When cleaning the impurities in the separation pool 2, rakes and other tools can be used directly to scoop them up to avoid the influence of the filter screen 4.
[0030] like Figure 5As shown, as an implementable embodiment, a top plate 8 is fixed above the two filter screens 4, and the clean water space enclosed by the two filter screens 4 and the top plate 8 and the diversion block 3 together constitute a triangular prism structure. At this time, the filter screen 4 is arranged at right angles to the inner bottom surface of the separation pool 2. On the basis of ensuring the diversion effect and facilitating the water flow to impact impurities to the end of the separation pool 2, when using a scooping tool to scoop out impurities such as branches, dead grass, branches and leaves in the separation pool 2, the interference between the mesh of the filter screen 4 and the scooping tool is reduced.
[0031] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
