Early rainwater exclusion system for clean rainwater catchment

摘要

The present invention relates to an apparatus for excluding an initial rainwater for collecting clean water, wherein the rainwater storage tank comprises an initial rainwater storage chamber and a clean rainwater storage chamber for separately storing rainwater and rainwater during rainy weather. A rotating support shaft rotatably intersecting to be located directly under the rainwater inflow pipe at an upper portion inside; A shaft support portion fixedly formed inside the rainwater storage tank so as to rotatably support the rotation support shaft; It is installed in a state mounted on the rotating support shaft to enable the seesaw operation, and a long length portion formed to have a long length so that the center of gravity is biased to one side based on the rotating support shaft, and a shorter length than the long length portion. A seesaw operating plate configured to be formed into a short length portion and formed to be formed on a side of a long length portion having a long center of gravity; It is formed in the same size as the width direction of the front and rear sides of the seesaw operation plate, and is upward to form a right angle with respect to the upper surface of the seesaw operation plate at a position biased toward the short length portion of the seesaw operation plate based on the center of the rotation support shaft. A short length portion formed by protruding in the direction so that rainwater flowing into the rainwater storage tank through the rainwater inflow pipe is stored in a certain amount on the upper surface of the seesaw operation plate so that the center of gravity of the seesaw operation plate has a short length on the long side It is an invention characterized by comprising a; rainwater storage plate to be moved to the side.
