A nature-friendly engineering method for purifying polluted water by having a system for purifying the polluted water into purified water is provided to discharge impurities and river water together and to purify the water naturally by fixing a front end of a piston rod of a second operating cylinder, rotating a water gate with 270°, and opening and closing a channel. A water gate is combined with an integrated control system and formed with a water gate plate(31) and two side plates(32) from the opened position of the water gate. An impact absorbing packing member is fixed to the outer part of the boundary area of the water gate plate and the side plates to be continuous to the longitudinal direction of the water gate. An operating link(34) is drawn to a lower side from a sealed space of a rotary shaft. A first operating cylinder is installed to the upper part of the sealed space. A support roller is rotatably mounted to the horizontal place to the first operating cylinder. A connecting member is connected to the front end of the operating link. A pressing plate(35) is withdrawn to the opposed direction of the withdrawing direction of the operating link through the rotary shaft. A support plate(62) and an operating plate are fixed to the outside of the pressing plate. A ring shaped slider(64) formed with an operating groove(65) is fitted from the operating plate to the support plate. A front end of the piston rod of a second operating cylinder(61) is rotatably fixed to the operating plate. The water gate is rotated with 270° through interlock of the operating cylinders to open and close a channel(11).
Abstract:
A method of purifying a polluted stream using a rotating water gate and an integrated control system is provided to prevent water leakage perfectly and to increase storage volume by installing a packing member, and to purify the stored water continuously by discharging the water even when the water gate is closed. In accordance with an integrated control system(100), a waterway(11) is formed between both side support structures(10), and a housing(20) is installed to a side of the support structure to form a closed space. A rotating water gate(30) is formed with an arc or triangular type gate plate(31), two side plates(32) connected perpendicularly to the gate plate, with a push bar between the side plates in application, and an axle(33) connected to the side plate. A packing member(40) is fixed longitudinally on the rotating water gate. A connection member is connected between a piston rod of an operating cylinder(51) and an operating link(34) via a support roller and the axle. At the opposite side of a pushing plate(35) attached to the axle, a support plate(62) and a operating plate(63) are fixed in a V shape. The water gate is rotated by about 270° according to interlocking of operating cylinders(51,61).
