Overlapping type rainwater collecting device

Abstract

The invention relates to an overlapping type rainwater collecting device, which comprises a plurality of longitudinal branch pipes, wherein each longitudinal branch pipe comprises a main pipe, a top pipe is arranged at the upper end of each main pipe, a tail pipe is arranged at the lower end of each main pipe, an annular rainwater collecting groove is formed in the upper part of each main pipe, a rainwater inlet hole is formed in the bottom part of the rainwater collecting groove of each main pipe, the outer wall of each top pipe and the inner hole of the corresponding tail pipe are matched in sizes, and the longitudinal branch pipes are sequentially connected in a head-to-tail way through the mutual sleeving of the corresponding top pipe and the corresponding tail pipe. The overlapping type rainwater collecting device has the characteristics that the structure is simple, the convenience in use is realized, the reasonable combination is realized according to the requirements, the requirement on floor area is lower, the rainwater collecting efficiency can be greatly improved, and the like.

Description

technical field [0001] The invention relates to a rainwater collection device, in particular to a combined rainwater collection device. Background technique [0002] Rainwater harvesting device is a very common equipment in arid areas, but with the development of modern society, the applicable range and application fields of rainwater harvesting device are constantly expanding. In order to expand the amount of rainwater collected, the current rainwater collection devices need to expand the lateral area of ​​the rainwater collection part as much as possible, but the expansion of this area is limited, especially in some facilities with small spaces. The efficiency of rainwater harvesting will be very limited, and as far as existing rainwater harvesting devices are concerned, there will be no ability to expand the efficiency of rainwater harvesting. [0003] However, we found that there is room for application of a relatively large amount of rainwater collection in a limited...

AI Technical Summary

Problems solved by technology

[0003] However, we found that there is room for a large amount of rainwater collection in a limited space. For example, the greening at the bottom of some viaducts cannot be directly watered by rainwater, and artificial or water diversion watering is completely required.

If rainwater is collected and irrigated on the upper side of the viaduct, a lot of labor and tap water can be saved, but when the problem arises, the area available for rain collection on the viaduct is very limited. If a traditional rainwater collector is used, the amount of irrigation is very small of
