{Static electricity eliminator with the function of removing suspended matters stuck in the screen}

[0001] The present invention relates to a vibration damper having a function of removing floating matter trapped in the screen, which can effectively remove the floating matter caught in the screen of the vibration damper.

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.

Such a vibration damper includes a frame installed on both sides of a water channel, a drive chain installed on the frame, a screen installed on the lower portion of the frame to catch floating objects included in the water stream, and a drive chain installed on the drive chain to infinitely follow the movement of the drive chain. It is generally composed of a rake which rotates on a track and sweeps up the floats hung on the screen, and a conveyor installed on the upper part of the frame to be connected to the screen and discharging the floats swept up by the rake.

However, if hard floats such as pebbles or plastics get stuck in the main screen and do not fall out, the rake, chain and drive device are overloaded and the vibration damper breaks down, and a major safety accident in which the waterway is blocked and the river overflows, as well as flooding of farmland or houses. Damage is occurring.

Accordingly, in Patent Registration No. 10-2074817 disclosed in the prior art, a fixing member extending to cross the screen, both ends of which are coupled to a chain provided in a vibration damper, and installed to move together with the chain, and the fixing member protruding from the fixing member in the direction of the screen A hinge bracket installed on the fixing member so as to have a structure of It is made in the form of a flat plate, and a comb-shaped rake for removing the floating matter caught on the screen is formed at the tip close to the screen, and the hinge bracket has a center coincident with the height direction center of the rake at the rear of the rake. It consists of a penetrating hinge shaft installed, and while rotating about the hinge shaft while being elastically supported by the torsion spring, the rake is a lifting posture close to the screen and a rotating member that is converted to an avoidance posture away from the screen. has been presented

In addition, in Patent No. 10-1746465, which is another prior art, a chain coupling part fixed to an endless chain, a rake rake extending outward narrowly from the chain coupling part, a triangular reinforcing rib fixed by welding at a right angle to the lower part of the rake rake, It has a symmetrical shape in which the width narrows in a curve toward the bottom, and a narrow and thin cutout is formed in the center in the longitudinal direction, the width of which is the same as the width of the rake rake, and the cutout is fitted to the reinforcing rib to fix the coupling Techniques including guide vanes that can be used have been documented.

However, in the prior art, it is impossible to adjust the elasticity according to the rotation of the rake, so it is impossible to customize settings in consideration of the characteristics of various types of floats in the field. In addition to shortening the lifespan of the rake, the reduction of the main screen filtration area led to a major safety accident in which the river overflowed.

On the other hand, in order to solve the problems of the prior art, the present applicant uses the sensing unit in Registered Patent No. 10-2153741 to detect an overload pattern generated in a plurality of rake units and emergency stop to prevent mechanical failure in advance. Although the technology has been registered in advance, there is no means for automatically removing the floating matter caught in the screen, so it is inconvenient that periodic maintenance by the operator is required. There was a problem in that it was not possible to filter out floating substances such as a large amount of inflowing garbage and contaminants.
