Description

A garden rainwater collection device

Technical field

The utility model relates to the technical field of rainwater collection and processing, in particular to a garden rainwater collection device.

Background technique

Due to environmental pollution and other factors, freshwater resources are becoming more and more important. As a clean freshwater resource, rainwater can be collected, processed and applied to alleviate water pressure. Especially in the field of municipal gardens, water consumption is very large. Tap water or pond water is usually used to irrigate the vegetation in the garden. Daily maintenance of the garden consumes a lot of water. Therefore, collecting rainwater in the garden and using it for vegetation can save money. Lots of water resources. Existing rainwater collection devices need to be cleaned and maintained after being used for a period of time to remove sediment in the device. However, since the rainwater collection devices are installed underground, cleaning up the sediment is very troublesome. For example, Chinese patent number 2023201508608 discloses a garden rainwater collection system. The rainwater collection pool, storage pool, and supporting permeable layer are all located underground. After a period of use, the supporting permeable layer needs to be cleaned of sediment, and the sedimentation in the storage pool The sediment also needs to be cleaned up. Since the entire project is located underground, it is very inconvenient to clean up.
