Unpowered self-cleaning rainwater filtering device

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to an unpowered self-cleaning rainwater filtering device which comprises a filtering well and an inspection well, and a water inlet pipe, a guide plate, a fixed seat, a fixed plate and a water outlet pipe are fixedly mounted on the filtering well from top to bottom; and a rotating shaft of a water wheel rotationally installed on the fixing base is in transmission connection with a T-shaped rod through a planetary reducer, a belt transmission mechanism and a gear reciprocating mechanism, the bottom face of a scraper fixedly connected with one end of the T-shaped rod is slidably attached to the outer side face of a filter plate, filter holes are formed in the filter plate in equal sequence, and inner gear rings installed at the two ends of the filter plate are in meshed connection with gears installed at the two ends of a cleaning roller. The bottom of the filter plate is fixedly connected with a fixed plate, a cleaning notch is formed in the filter well on the upper side of the fixed plate, a baffle is fixedly mounted on the outer side of the cleaning notch, and the cleaning roller and the scraper are driven by kinetic energy of water flow to reciprocate and enable the cleaning roller to rotate, so that garbage attached outside the filter plate and in filter holes is effectively cleaned and scraped, and small-size garbage is isolated and filtered; and labor is reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a non-powered self-cleaning rainwater filtering device. Background technique [0002] The collection and utilization of rainwater can solve a series of contradictions such as water shortage, environment and ecology. We can use the collected rainwater for daily life, such as washing cars, washing toilets, watering greenery, flushing roads, fire fighting and so on. The collection and utilization of rainwater can also reduce the runoff of rainwater on urban streets, reduce the pressure on urban drainage, effectively reduce the confluence of rain and sewage, and reduce the pressure on sewage treatment. [0003] Before the rainwater flows into the rainwater pipe, it first passes through the rainwater grate to filter out the larger garbage, and then discharges it into the rainwater well through the municipal rainwater pipe. The garbage blocked outside the rainwate...

AI Technical Summary

Problems solved by technology

[0003] Before the rainwater flows into the rainwater pipe, it first passes through the rainwater grate to filter out the larger garbage, and then discharges it into the rainwater well through the municipal rainwater pipe. The garbage blocked outside the rainwater grate can be visually observed, which is convenient for the management personnel to clean and maintain. However, Smaller garbage such as camphor leaves and cigarette butts will pass through the gaps in the rainwater grate and flow into the rainwater pipes and rainwater wells driven by the water flow, causing blockage of the municipal rainwater pipes after a long time
