The use of a low voltage power source to operate a mechanical device to clean a screen in a combined sewer overflow system

摘要

A low voltage power source comprises a wind turbine 1 or a photovoltaic cell 2, or a combination of both, which charge a battery pack 3. The battery pack will in turn power an electric motor 5 which will drive a hydraulic pump 6 which charges an accumulator or pressure reservoir. The stored energy will be used to operate a hydraulic ram10 which operates a machine to clean the filter screen 14 in a combined sewer overflow system 13. The system controls 11 will incorporate an alarm system with the facility to report faults and access controls through the medium of a cellular phone.
