When the hydraulic cylinder is started, the transmission device and the rod system can be driven to enable the gate to work. Present a plurality of pneumatic cylinders need two or even a plurality of actuating mechanism, and comparatively extravagant source material, a plurality of actuating mechanism comparatively occupy the dam space simultaneously, cause certain economic loss. In addition, when the gates are opened by a plurality of hydraulic cylinders simultaneously, the opening angles are asynchronous, the pressure on the left gate and the right gate is different, the pressure on one gate is higher, the pressure on the other gate is lower, and especially when flood discharge occurs, when the two gates rotate asynchronously, the hydraulic cylinders are easily damaged by large water pressure, the hydraulic cylinders are replaced or maintained, and large maintenance cost is caused. At present, many gates do not need to walk through ships, only need to regularly discharge flood and drain water to a specific time, only need a tiny drainage channel, and only few phenomena appear from the gates through ships. The hydraulic cylinder is easy to damage a gate through which ships pass in rare cases, the hydraulic oil is high in cost and difficult to process, the environment is polluted, the viscosity of the hydraulic oil is high, the resistance is high, and the use cost performance is relatively low.
