Description

Vibrator with electric potential screen and elevating structure of vibration isolator

The present invention relates to a vibration isolator used to remove impurities floating on a waterway using a screen, and more particularly, the entire vibration isolator including a main screen and a potential screen is installed so as to be able to rotate entirely. By installing only the electric potential screen so that it can be individually rotated and controlled up and down as needed, the natural flowing water in the installed state of the vibration damper is lifted by the upward/downward rotation process on the waterway. The present invention relates to a vibration damper having an electric potential screen and an elevating structure of the vibration damper.

In general, a vibration damper is installed and used in pumping stations, drainage pumping stations, wastewater treatment plants, water intake stations, related waterways and dams by using power, and is equipped with a screen to prevent various impurities floating along with running water from passing through. It is a mechanical device to remove impurities from the screen.

Such a vibration damper is usually installed on a frame installed in a waterway, and a main screen consisting of a plurality of screen bars inclined at a certain angle to the bottom surface to filter out impurities floating along with running water, and installed at the front bottom of the main screen. A potential screen to block and filter out impurities passing between the main screen and the bottom surface; an apron installed on the upper side of the main screen to prevent impurities from falling to the lower side when passing through the upper portion; and an electrical potential with the main screen. It consists of a configuration including a rake having a rake-shaped structure fixedly installed on the endless chain to remove impurities between the screens.

However, the conventional vibration damper as described above is often fixedly installed on the waterway in many cases.However, the flow of water is hindered by blocking the waterway, and the problem of making natural flowing water difficult even when there are no impurities. There was this.

On the other hand, as for the conventional vibration damper, a screen rotation type vibration isolator is proposed and disclosed in Korean Patent Registration No. 10-1972705, and an individual rake rotation device for a vibration isolator is proposed and disclosed in Korea Utility Model No. 20-0471404. In Korean Patent Publication No. 10-2014-0033613, a vibration damper including an electric potential screen is proposed and disclosed.

In the domestic registration patent No. 10-1972705, the main feature is that the screen is provided in an individual rotating structure, and the domestic utility model No. 20-0471404 is characterized in that the rake is individually rotatable. , In the Korean Patent Publication No. 10-2014-0033613, it is characterized in that the electric potential screen is individually rotatable.

However, the domestic registration patent No. 10-1972705 is a patent for a structure that vertically lifts the entire vibration damper, and there must be a rail made of a steel structure that can be lifted, and it is a structure that receives excessive load on the rail side when vertically rising. If there is a structure (such as a monorail hoist) in the rail, interference will occur in the rail. In addition, in order to operate the vibration damper in an emergency, it is not suitable as a structure to lift initial impurities because the vibration damper can be driven after it is settled in the waterway by descending.

The domestic registered utility model No. 20-0471404 is a rake tilting device that is not a technology for lifting and lifting a vibration damper. It is a structure that returns to its original state.

The Korean Patent Publication No. 10-2014-0033613 is a device that lifts a vibration damper using a wire rope and a hydraulic cylinder. If the tension of the wire rope is increased by using for a long time, the vibration damper may be twisted, and there is no safety device. When a problem occurs in the hydraulic pressure of the cylinder, an accident may occur, and in order to operate the vibration damper in an emergency, since the vibration damper can be driven after descending to the waterway, there is a problem that is not suitable as a structure to lift the initial impurities.
