[0016] Compared with the prior art, the present invention has the following beneficial effects: The green building rainwater collection and purification device of the present invention realizes the effective collection and purification of rainwater by setting a collection tank and a purification mechanism. The separation pipe and the external filtering transverse pipe can filter out impurities and particulate matter in the rainwater, thereby improving the purity of the rainwater. The cleaning plate can clean the inner wall of the separation pipe when the top rotating shaft rotates, thereby preventing the accumulation of impurities and maintaining the smooth flow of the filtering channel. The coordinated design of the front movable plate and the separation column enables the front movable plate to remove the debris on the separation column when the rainwater flows or the device moves, thereby further ensuring the purification effect. The V-shaped filter plate can improve the filtering efficiency and help to further separate impurities. The bottom collection pipe enables the purified rainwater to be easily discharged from the collection tank, and the bottom collection pipe is rotatably connected to the collection tank, which is convenient for disassembly and cleaning.

[0017] Specifically, the outer filter transverse tube is placed below the rainwater. When the rainwater falls to the outside of the outer filter transverse tube, it impacts the outer filter transverse tube, causing the outer filter transverse tube to rotate. The debris in the rainwater also falls to the top of the outer filter transverse tube, some falls to the front of the rear movable plate, and some falls to the ground along the rolling of the outer filter transverse tube. In this way, the large debris brought by the rainwater during its falling process will not cause blockage to the purification device, and the rainwater can be collected and purified for a long time.

[0018] An outer filtering transverse tube is fixed on the outer sides of the left separation pipe and the right separation pipe, and the outer filtering transverse tube is placed below the rainwater. When the rainwater falls on the outer side of the outer filtering transverse tube, it impacts the outer filtering transverse tube, causing the outer filtering transverse tube to rotate, and small impurities in the rainwater enter the inner side of the outer filtering transverse tube. Then, as the left supporting cleaning plate and the right supporting cleaning plate scrape the left separation pipe and the right separation pipe respectively, the small debris falls along the outer ends of the left separation pipe and the right separation pipe. The left filter plate and the right filter plate are fixed inside the top rotating shaft. The small debris falls on the top of the left filter plate and the right filter plate, and then falls to the inside of the bottom collecting circular tube along with the left filter plate and the right filter plate, and slides out of the collecting rectangular tank along the bottom collecting circular tube. In this way, large and small debris in the rainwater can be separated, so that the rainwater collection and purification device will not be blocked, the service life of the device is extended, and there is no need to manually clean up the garbage.

[0019] Furthermore, by fixing the left fixed disc and the right fixed disc on the inner side of the left outer limiting disc and the right outer limiting disc, a left supporting cleaning plate is fixed on the inner side of the left fixed disc, and a right supporting cleaning plate is fixed on the inner side of the right fixed disc, the left separation pipe and the right separation pipe are sleeved on the outside of the left supporting cleaning plate and the right supporting cleaning plate, and an outer filtering transverse tube is fixed on the outer side of the left separation pipe and the right separation pipe. When rainwater falls on the outer side of the outer filtering transverse tube, it impacts the outer filtering transverse tube, causing the outer filtering transverse tube to rotate. The outer filtering transverse tube rotates with the help of the impact of rainwater, without providing external energy. The device itself adjusts the rotation speed according to the amount of rainwater, which is conducive to cleaning up debris.

[0020] Furthermore, the arrangement of the left outer limiting plate and the right outer limiting plate limits the movement range of the separation pipeline, thereby ensuring the stability of the device during operation.

[0021] Furthermore, the friction contact design between the left supporting shaft and the right supporting shaft and the front movable plate ensures the flexibility of the front movable plate and prevents the front movable plate from excessive movement.

[0022] Furthermore, the inclination of the bottom collecting pipe is to facilitate the discharge of rainwater.

In this way, large and small debris in the rainwater can be separated, so that the rainwater collection and purification device will not be blocked. When rainwater falls to the outside of the outer filter transverse tube 202, it impacts the outer filter transverse tube 202, causing the outer filter transverse tube 202 to rotate. The outer filter transverse tube 202 rotates with the impact of rainwater, and no external energy is provided. The device itself rotates at a speed according to the amount of rainwater.
