HYDRAULIC WATER GATE APPARATUS

摘要

PURPOSE: A hydraulic water gate apparatus is provided to lengthen the life span of a hydraulic cylinder by making a support part control a water gate part in multi stages according to the water level and preventing water pressure from being directly transmitted to the hydraulic cylinder by the support part. CONSTITUTION: A hydraulic water gate apparatus has a water gate(112) the lower part of which is rotated by a rotating shaft(16). The water gate is mounted to a post frame(14) formed to a side of a drain ditch(12) of a bank(10). The hydraulic water gate apparatus comprises a water gate part(110) having a guide rail(114) vertically extended from the upper part of the water gate to the lower part, on the rear of the water gate; a support part(120) having a first fixing bracket(122) arranged on the bottom surface of the drain ditch, and a support frame(130) rotatably mounted to the first fixing bracket and selectively guided along the guide rail; and a hydraulic part(150) having a second fixing bracket(152) arranged on the bottom surface of the drain ditch between one side of the post frame and the first fixing bracket, and a hydraulic cylinder(160) one end of which is rotatably mounted to the second fixing bracket. A cylinder rod(164) is extended to the other end of the hydraulic cylinder. The hydraulic cylinder is mounted to the support frame through the first fixing bracket. The hydraulic cylinder controls the height of the water gate by rotating the support frame about the first fixing bracket.
