A hydrological system configured to constitute a completely flawless support system by configuring a hydrologic support device so that the hydraulic force supporting the hydraulic cylinder applied to the hydrologic door is not pushed.

摘要

A water gate system is provided to improve reliability of water gate operation because the fluid pressure of the hydraulic cylinder does not leak and the state thereof can be maintained. A water gate system is as follows. A locking member(40) with a hanging projection(41) is fixed on one side of a water gate(20). The hanging projection of the locking member on the hydraulic cylinder is selectively held in the projection of the hydraulic cylinder according to expansion and contraction of the hydraulic cylinder(30). For releasing locking of the locking member, a locking release cylinder(50) is connected to the top of the hydraulic cylinder and is allowed to rotate. In order to release locking of the locking member in the front end of a cylinder rod, a locking release device(52) with an incline is fixed.
