Description

Hydraulic Hydro Device {FLOODGATE USING HYDRAULIC CYLINDER}

The present invention relates to a hydraulic hydrological device, and more particularly, it is possible to prevent the sluice from buckling by the water pressure or sagging due to its own weight, and can easily open and close the gate with little force. The present invention relates to a hydraulic hydrological device which prevents the actuated hydraulic pressure from being directly transmitted to the hydraulic cylinder, thereby extending the service life of the hydraulic cylinder.

Irrigation canals, rivers and reservoirs are used for the purpose of storing a certain amount of water for proper use in farmland management or irrigation water. Such a water channel is provided with a hydrological device that opens and closes the water gate to manage water, that is, in case of drought, the water is stored and rained, so that water is released when the amount of water is large.

Such a hydrological device discloses a method of opening and closing a water gate by rotating an adjustment handle, and a method of rotating a water gate or lifting a water gate using a hydraulic cylinder.

The hydrological device for rotating the water gate using the above-described hydraulic cylinder can be largely divided into a conduction type in which the water gate is conducted in the same direction as the discharged water and a bottom discharge type in which the water is discharged to the bottom of the water gate.

The conduction hydrograph has the advantage that foreign substances can be discharged completely without flooding when the flood occurs, and the lower drainage hydrograph does not need dredging because sediment does not accumulate, and because the fish naturally forms, There is an advantage that can reduce the construction period and construction cost because no construction is required. These conducting hydrologic devices and bottom drain hydrologic devices can minimize flood damage by horizontal opening during rapid water level increase.

By the way, the above-described conduction and bottom discharge type hydrological device has the advantage of being able to easily open and close the water gate by using a hydraulic cylinder, but because the hydraulic cylinder is configured to support the water gate for a long time, the hydraulic pressure acting on the water gate remains hydraulic There is a problem that the life of the hydraulic cylinder is shortened to be delivered to the cylinder.

In addition, since the conventional hydrological devices have a relatively extended structure in the horizontal direction of the hydrologic gate, the hydrologic gate is buckled by the hydraulic pressure acting on the hydrologic gate or the hydrological gate sags due to the weight of the hydrologic gate itself.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention is to prevent the slugging of the water gate by the water pressure or sagging due to the weight of the water in advance, and to facilitate the water gate with a small force In addition to opening and closing, it is to provide a hydraulic hydrological device that can prevent the hydraulic pressure acting on the water gate to be directly transmitted to the hydraulic cylinder to extend the service life of the hydraulic cylinder.
