In general, in places where water is managed, such as rivers, water intakes, and stormwater treatment facilities, a bar screen, trash remover is installed to block the waterway to prevent various floating debris from entering through the waterway. have.

Vibration dampers are largely classified into rotary dampers and hydraulic dampers according to their installation structure.

The rotary damper is applied to water intakes, water purification plants, pumping stations, and sewage treatment plants with a depth of 3 to 5 m as in Patent Documents 0001 (KR 10-2139242 B1) and Patent Documents 0002 (KR 10-2096805 B1), and is circulated by endless chains. It has the advantage that it can be operated in conjunction with the pump and can be continuously processed with several rakes, and can be operated as an unmanned automatic operation system by installing one unit in each waterway.

However, there is a disadvantage in that the installation cost is excessive because it must be installed in a large number according to the width of the water channel.

And as in Patent Document 0003 (KR 10-1346270 B1) and Patent Document 0004 (KR 10-1065812 B1), the hydraulic vibration damper reciprocates along the transfer rail on the upper side of the screen and removes contaminants using a rake installed at the end of the boom. In order to do this, the installation cost is reduced compared to the rotary vibration damper, but there is a disadvantage that a lot of time is consumed to collect contaminants.

On the other hand, the present inventor proposes Patent Document 0005 (KR 10-2152208 B1) in order to prevent flood damage in the upstream area due to weather changes such as heavy rain or rainy season because it is possible to effectively forcibly drain water from the upstream side to the downstream side. there is a bar

In the case of the vibration damper of Patent Document 0005 (KR 10-2152208 B1), when the water level on the downstream side is lower than the water level on the upstream side and there is no need to forcibly drain the water by a pump, the vibration damper is raised in the upper direction of the water channel using an actuator. , there is a cumbersome need to lift the screen upwards using an actuator and a separate hoist.
