The present invention relates to a water gate device, a moisture detector for checking a reducer included in the water gate device, and a method for inspecting the reducer using the same.

In general, sluice gates, a type of hydraulic facility, are installed in water supply and sewage systems, urban sewage treatment plants, water treatment plants, agricultural irrigation canals, and other related waterways or other drains that come into contact with rivers.

The floodgate regulates the flow rate by opening and closing by rising and falling, maintains the water depth, and performs the function of preventing backflow of water due to floods, etc.

Windlasses using motors are widely used for sluice gates, and windlasses are generally operated in an electric manner and then implemented in a manual manner when the clutch is disconnected. Among the various types of windlassing machines that use motors, the pinjack windlass, which transmits the power of the motor to the sluice through a rack bar, and the drum windlass, which transmits the power of the motor to the sluice through a wire rope wrapped around a drum, are widely used.

For example, a conventional sluice device includes a frame-shaped sluice gate installed across a waterway, a sluice gate installed to raise and lower the sluice frame, a rack bar installed on the sluice gate to raise and lower the sluice gate, and a sprocket that engages the rack bar. It may include a reducer having a reducer, a main reducer having a motor that provides power to the reducer, and a band-type brake built into the reducer to reduce or stop the speed of the reducer.

This conventional water gate device has the following problems in maintaining the reducer.

The reduction gear box that forms the exterior of the reducer is always exposed to the outside, and therefore the function of the air breather, which discharges air mixed into the oil tank of the reducer, is reduced or easily damaged.

Meanwhile, for maintenance of the reducer, the manager checked the condition of the oil and the presence of moisture inflow by directly draining the oil inside the reducer through the drain valve. This inspection method not only requires a lot of manpower and time for inspection, but also has many difficulties in regular inspection. Additionally, if impurities such as moisture are left inside the reducer for a long time, the lifespan of the reducer may be rapidly reduced. Therefore, there is a need for a method to more easily inspect the reducer included in the water gate device.

Various embodiments of the present invention are intended to solve the above problems, including a water gate device that not only facilitates inspection of the reducer but also shortens the inspection time, a moisture detector for inspecting the reducer included in the water gate device, and a moisture detector using the same.
