Description

Technical Field

[0001] The utility model relates to the technical field of water gates, in particular to a travel limiting device for a water gate hoist. Background Art

[0002] A sluice gate is a low-head hydraulic structure built on rivers and channels that uses gates to control flow and adjust water levels. Closing the gates can block floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic water. Opening the gates can discharge floods, waterlogging, abandoned water, or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluice gates are widely used as structures for retaining, discharging, or taking in water.

[0003] During the operation of the sluice gate, if the gate is affected by debris and becomes stuck, if it is not observed for a long time, the force of the screw opening and closing mechanism will cause the screw to bend or the gate to deform, affecting the integrity of the sluice gate.
