OPENING DETECTOR FOR HYDRAULIC CYLINDER DIRECT SUSPENDING TYPE SLUICE GATE

摘要

PROBLEM TO BE SOLVED: To increase the opening detection accuracy of a sluice gate. SOLUTION: A converting mechanism for converting the lifting amount of a sluice gate 3 lifted up and down by a hydraulic cylinder 5 into the amount of rotation comprises a pair of upper and lower sprockets 6 and 7 installed on the upper side of a water channel 2 having the openable sluice gate 3, a chain 8 stretched between both sprockets 6 and 7, and an arm 9 for connecting the chain 8 to the sluice gate 3.
