When the width-height ratio of the gate body is less than 1, the number of the hydraulic cylinder barrels and the multi-stage piston rods of the hydraulic hoist is 1, and the hydraulic cylinder barrels and the multi-stage piston rods are vertically arranged along the central line of the gate body; when the width-height ratio of the gate door body 1 is larger than 1, the number of the hydraulic cylinder barrels and the multi-stage piston rods of the hydraulic hoist is 2, and the hydraulic cylinder barrels and the multi-stage piston rods are symmetrically and vertically arranged along the central line of the gate door body.
The number of stages of the multi-stage piston rod is at least 2.
When the gate body is opened and closed in the working condition that the difference of the upstream and downstream water heads is small and the gate can be closed by self weight, the multistage piston rod can be replaced by the multistage piston rod.
The beneficial effects of the utility model are that, through the structure with the gate door body and multistage hydraulic cylinder combination, can rely on the nimble free gate of opening and close of self structure, need not adopt extra equipment to assist and open and hang the gate, avoid influencing the operation of opening and close of gate because of the unstability of extra equipment, realize the safe and reliable operation of gate equipment, improve the security of floodgate hole greatly.
