Abstract

TopSink is an automatic drainage device that includes a floatable funnel with a flexible discharge line connected to a discharge port on an interior of a barrel. The funnel rises with the level of the collected water and or rain until it nears the barrel's maximum capacity, when it is triggered to sink and drain out a predetermined volume of water. As the funnel sinks it continues to drain water until it is caught by at least two predetermined depth adjustable rods. The catch rods establish how much water is drained from the barrel each time capacity is reached. Water or rain continues to drain from the TopSink until the water or rain level gets to the level of the catch rods. Upon further water or rain collection, the funnel begins to float again on the surface of the water, until capacity is reached again.

Claims4

Dependent claims

A liquid storage device comprising:

a sealed liquid storage container;
a floatable funnel inside of said liquid storage container having a top and bottom opening, an internal standpipe attached to the bottom opening within a base of the floatable funnel;
a flexible discharge line connected to the bottom opening of said floatable funnel and extends to a port on a side of an interior of said liquid storage container;
a shut off valve on an exterior of said liquid storage container, connected to an end of said flexible discharge line via the port;
the liquid storage container includes intermittent indentations at varying depths inside said liquid storage container, and at least two adjustable rods are attached across the intermittent indentations at a desired depth, wherein the floatable funnel rests on between the at least two adjustable rods when the floatable funnel completes a drainage cycle.
