Rainwater filtering device for inflow path

摘要

Collected rainwater is led to a rainwater containing section by an inflow path. A water-permeable tube body extends vertically in the middle of a vertical pipe located immediately before a position at which the rainwater flows into the rainwater containing section. A bag-like filter having an open upper end and a closed lower end is contained in the tube body or covers an outer side of the tube body, and the bag-like filter captures dust in the rainwater while allowing the rainwater to pass through the bag-like filter. A mounting and dismounting means is provided to the vertical tube in order to dismount the tube body and the filter from the vertical pipe and to mount the tube body and the filter to the vertical pipe.

1. A rainwater filtering device for an inflow path, comprising:
an inflow path through which collected rainwater is led to a rainwater containing section; a water permeable tube body provided in a vertically extending manner in the middle of a vertical member located immediately before a position at which the rainwater flows into the rainwater containing section in the inflow path; a bag filter that has an open upper end and a closed lower end, the filter being provided on the tube body, and wherein the filter captures dust in the rainwater while allowing the rainwater to pass therethrough; and a mounting and dismounting member provided to the vertical member in order to dismount the tube body and the filter which are provided to the vertical member from the vertical member and to mount the tube body and the filter to the vertical member, wherein the mounting and dismounting member has a rainwater guide detachably inserted with a gap into an upper part of the tube body, and a ring-like path surrounded by an inner peripheral surface of the tube body and an outer peripheral surface of the rainwater guide is configured so that the amount of rainwater permitted to pass through the lateral cross-sectional area of the ring-like path corresponds to the maximum amount of rainwater which passes through the inflow path.
