Abstract:
The present invention relates to an environmentally friendly method for naturally purifying polluted river water using the natural action of river water and for restoring a natural ecosystem by forming a fishway to purify polluted river water flowing to a river by forming a fishway for ecosystem restoration and discharging polluted river water flowing to the river after purifying it; and to maintain a predetermined amount of river water by preventing river water from being completely discharged through the bottom water discharge passage of a floodgate during a dry season.
Abstract:
The present invention provides an environmentally friendly construction method capable of naturally purifying contaminated stream water and restoring a natural ecosystem by forming a fishway for restoring an ecosystem. The present invention is characterized by naturally forming the fishway with a multifunctional movable weir sluice gate (700) combined with a water purifier and purifying the contaminated stream water.
Abstract:
The present invention relates to an environmentally friendly construction method for purifying clean river water by perfectly collecting all kinds of contaminant molecules and wastes flowing in a river, a stream, or a lake and a point contamination source and non-point contamination source removal system. The point contamination source and non-point contamination source removal system is characterized by purifying the contaminated river water to the clean river water. A multipurpose movable weir sluice includes two inlets and four outlets naturally purifying the contaminated river water flowing in the river from the point contamination source and non-point contamination source.

PURPOSE: A floodgate device for facilitating deformation prevention and maintenance is provided to prevent a floodgate from buckling due to water pressure when closing the floodgate and from sagging when opening the floodgate and to facilitate to maintain a rotary shaft for connecting the floodgate and an operation cylinder. CONSTITUTION: A floodgate device (100) for facilitating deformation prevention and maintenance comprises a floodgate unit (110), an opening and closing operation unit (120), and a deformation prevention unit (160). The floodgate unit is arranged in a drain (10) and comprises a floodgate (112), a housing (116), and a pair of rotary brackets (114). The floodgate opens or closes the drain. The housing supports both ends of the floodgate. A rotary bracket is extended to the outside of the floodgate. The opening and closing operation unit is arranged inside the housing and comprises a rotary shaft (140), an operation cylinder (122), and an operation link member (134). The operation cylinder rotates the rotary shaft to open or close the floodgate. The operation link member connects the operation cylinder and rotary shaft. The deformation prevention unit comprises a plurality of support roller units and a plurality of support units. The support roller unit is arranged on one swollen side of the floodgate in the longitudinal direction of the floodgate. The support unit is equipped in the sinking part of the drain by facing the support roller unit to guide and support the support roller unit.

PURPOSE: A water gate including a locking device is provided to stably maintain the water gate in a standing state when fluid pressure of a hydraulic cylinder is not supplied. CONSTITUTION: A water gate including a locking device comprises housing(10), a water gate(20), a rotary link(30), a variable link, a rotary cylinder(50), and a locking device(60). The housing comprises a pair of walls(11) which are separated from each other and bottom surface(12). The water gate is installed inside the housing and comprises a rotary shaft at the lower part thereof. The rotary shaft protrudes from both sides by penetrating the wall of the housing. The rotary link is installed outside the housing and is integrally connected to the end of the rotary shaft. The variable link is installed inside the rotary link in order to rotate. One side of the rotary cylinder is hinged at the upper end of the variable link, and the other side of the rotary cylinder is fixed to the bottom surface of the housing. The locking device comprises an insertion groove, a fixing shaft, and a fixing cylinder. The insertion groove is formed at the end of the rotary shaft, and the fixing cylinder moves the rotary shaft. The fixing shaft is inserted into the insertion groove and fixes the rotary shaft.
