How to effectively prevent accidents caused by the operation of gate operators has been a concern for many users of these machines in recent years. Currently, screw-type gate operators are widely used in various canal structures and water intake projects due to their simple structure, ease of installation, and affordability. However, many of these screw operators lack effective safety measures to prevent accidents. Even with limit switches installed on portable electric gate operators, they can only serve as limiters, and a slight mishandling during operation can lead to bending of the screw, breaking of the operator's end cover, or snapping of the operator beam, causing cracks and damage to the reinforced concrete beam. In severe cases, it can result in the displacement, rotation, or overturning of the operator platform (beam), potentially causing injuries or even fatalities. Electric gate operators can also lead to motor overload and burning, severely impacting the safety of the project and threatening the operators' safety. Several accidents involving the top gate have occurred at small and medium-sized reservoirs during the use of portable electric screw operators, highlighting the risk of such accidents. Measures should be taken to prevent these incidents and address this pressing issue.
