Technical Field
[0001] This utility model relates to the field of rainwater harvesting and utilization technology, and in particular to a compact rainwater harvesting and utilization device. Background Technology
[0002] Rainwater harvesting systems are devices or systems used to collect, store, and treat rainwater, aiming to convert natural precipitation into reusable water resources. These systems purify and optimize rainwater through a series of technological means (such as filtration, sedimentation, and disinfection) to meet specific needs, such as irrigation, flushing, cleaning, industrial water, and even drinking water. However, in existing rainwater harvesting systems, the sedimentation box is usually located at the bottom of the rainwater collection tank. Cleaning the sedimentation box requires manual removal from the bottom of the collection tank, which is time-consuming, labor-intensive, inefficient, and inconvenient.
[0003] Therefore, a compact rainwater recycling device has now been developed that can automatically lift the sedimentation box, improving the ease of cleaning the sedimentation box. Utility Model Content

The left side of the water inlet frame 205 is sloped to facilitate rainwater collection. The sedimentation box 206 is placed inside the lower side of the rainwater collection tank 2. The lower side of the first filter screen 203 is in contact with the sedimentation box 206. The cylinders 207 are connected to the inner sides of both the front and rear parts of the rainwater collection tank 2. The telescopic ends of the cylinders 207 are connected to the sedimentation box 206. The control box 208 is connected to the front side of the upper right part of the rainwater collection tank 2.

[0022] like Figure 5 As shown, the drainage assembly includes a drain pipe 401, a booster pump 402, an ultraviolet sterilizer 403, a solar panel 404, and an inlet pipe 405. The drain pipe 401 is connected to the lower right part of the clear water tank 4. The booster pump 402 is connected to the inner side of the lower right part of the clear water tank 4 and is connected to the drain pipe 401.
