Title:
RAINWATER DRAIN CONTAMINANT FILTRATION APPARATUS AND MONITORING SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/022587
Kind Code:
A1
Abstract:
Provided are a rainwater runoff contaminant filtration apparatus and a monitoring system therefor. The rainwater runoff contaminant filtration apparatus, according to one embodiment of the present invention, comprises: a main body which has rainwater runoff inflowing via a top-end-opened opening, and has the rainwater runoff discharged via a discharge port formed on the lower portion of one side surface; a filtration part which is positioned inside the main body and filters the rainwater runoff inflowing via the opening; a collection part which is connected to the filtration part, collects the rainwater runoff and provides same to the inside of the filtration part; a connection detection part which has a spring cylinder for connecting the filtration part and the collection part, and detects the weight of the filtration part on the basis of the reciprocating motion of the spring cylinder; and a communication part which transmits, to the outside, the weight of the filtration part detected by the connection detection part, wherein the connection detection part comprises a contactless sensor which is positioned on the outside of the spring cylinder, and a magnet which is positioned inside the spring cylinder and is linked to the movement of the spring cylinder, and the communication part transmits, to the outside, a signal generated by the contactless sensor which has detected the magnet.
