Abstract:
The present disclosure relates to a hydraulic pulling water gate system. According to the present disclosure, the risk of working fluid leakage due to hydraulic system damage caused by a load of a water gate which is opened and closed repeatedly is reduced and an abnormal elevation of the water gate can be prevented. According to one aspect of the present disclosure, there is provided a hydraulic pulling water gate system including a hydraulic cylinder that is arranged with length in an up-down direction so that the working fluid flows in and out selectively; a piston rod that is arranged in a longitudinal direction of the hydraulic cylinder, is pulled in selectively into the hydraulic cylinder in response to the working fluid inflow and outflow, and is in linear motion in the longitudinal direction; the water gate that is coupled with one end of the piston rod and is moved upward and downward in conjunction whit the linear motion of the piston rod; and load distribution units that are provided at an outer circumference of the piston rod and at an outer circumference of the hydraulic cylinder, are provided to face each other and be in motion in opposite directions when the piston rod is in linear motion, and are coupled with each other when the piston rod is stopped so that the motion of the piston rod by the load of the water gate is limited.

PURPOSE: A turnover type floodgate is provided to improve the durability and operability by employing a circular link and prevent the standing floodgate from being turned over in spite of a fail of hydraulic equipment. CONSTITUTION: A turnover type floodgate comprises a floodgate(10), a rotary shaft, a support bracket(30), a circular link(40), a hydraulic actuator(50), a housing(60), a locking unit(80), and a sealing unit. The floodgate blocks up the river water flowing from the upper stream of a river. The rotary shaft is fixed to both lower sides of the floodgate. The support bracket is provided on both sides of the floodgate to support the rotary shaft. The circular link is connected to the rotary shaft at the central portion and coupled with a fastener(57) of a piston rod by a fixing pin(P1) at a portion separate from the central portion. The hydraulic actuator rotates the circular link to turn the floodgate. The housing embeds the support bracket, the circular link, and the hydraulic actuator. The sealing unit prevents between the water leakage between the inner plate of the housing and both sides of the floodgate.
