Abstract

An insert (400) for a rainwater downpipe (300) is fluidly coupled between a first section (310) and a second section (320) of the rainwater downpipe (300). A rainwater reservoir (500) is defined within the insert (400) to store the rainwater received from the first section (310) therein. The rainwater reservoir (500) includes a side surface (510), a bottom surface (520) and an outlet opening (522) fluidly coupled to the second section (320). A valve element (530) is disposed within the rainwater reservoir (500) to allow or deny the passage of the stored rainwater in the rainwater reservoir (500) through the outlet opening (522). The insert (400) is characterized in that the side surface (510) of the rainwater reservoir (500) further defines a rainwater harvesting opening (549) adapted to allow access to the rainwater stored in the rainwater reservoir (500).

First claim

The invention claimed is:

1 . An insert for a rainwater downpipe for storing and accessing the stored rainwater,
the rainwater downpipe defining a first section and a second section disposed downstream of the first section, and the insert comprising: a top portion fluidly coupled with the first section; a bottom portion fluidly coupled with the second section; wherein the insert is inserted in the rainwater downpipe with the insert overlapping the first section and the second section; and a rainwater reservoir defined between the top portion and the bottom portion and defining a first chamber and a second chamber, wherein the first chamber is adapted to store the rainwater received from the first section therein, the rainwater reservoir including a side surface and a bottom surface; an outlet opening fluidly coupled to the second section; a valve element disposed within the rainwater reservoir, the valve element adapted to move between a first position and a second position such that the valve element denies passage of the stored rainwater in the rainwater reservoir through the outlet opening in the first position and the valve element allows passage of the stored rainwater in the rainwater reservoir through the outlet opening in the second position; and a biasing element coupled with the valve element on one end and any one of the side surface or the bottom surface on the other end, wherein the biasing element biases the valve element in the first position, and wherein the biasing element is adapted to allow the valve element to move to the second position after a weight of the rainwater stored in the rainwater reservoir crosses a threshold weight, the side surface further defines a rainwater harvesting opening adapted to allow access to the rainwater stored in the rainwater reservoir, wherein the overlap of the insert and the first section of the rainwater downpipe allows to additionally store water within the first section above the insert, and wherein the biasing element is centrally disposed along an axial direction of fluid flow of the rainwater.

2 . The insert of claim 1 , wherein the rainwater harvesting opening includes a water filter.

3 . The insert of claim 1 , wherein the rainwater harvesting opening is configured to be fluidly connected to a pump such that the pump is fluidly connected to one or more of an irrigation tank, or a water filtration tank.

4 . The insert of claim 1 , wherein the rainwater harvesting opening includes a cap for covering the rainwater harvesting opening.

5 . The insert of claim 1 , wherein the rainwater harvesting opening is a circular opening.

6 . The insert of claim 1 , wherein the rainwater harvesting opening includes latches or a threaded coupling portion for secure connection with one or more hoses.

7 . The insert of claim 1 , wherein the biasing element is one or more of a compression spring, or a torsion spring.

8 . The insert of claim 1 , wherein the top portion and the bottom portion of the insert are telescopic along the central axis of the rainwater downpipe.

9 . The insert of claim 1 , wherein the rainwater reservoir defines the first chamber and the second chamber such that in the first position of the valve element, the rainwater enters the first chamber and in the second position of the valve element, the rainwater enters the second chamber.

10 . The insert of claim 1 , wherein the bottom surface of the rainwater reservoir defines the outlet opening.

11 . The insert of claim 1 , wherein the outlet opening allows passage of foreign elements along with the rainwater.
