Claims

[Scope of utility model registration request]

In a device having a security gate for opening and closing an opening formed in a main gate for opening and closing a waterway, the upper end of the security gate is supported via a horizontal pin on the rear surface of the main gate, and a gate is attached to the lower end of the security gate. A second stopper is provided on the main gate side so as to be movable in and out of the first stopper, and a biasing means for biasing the second stopper toward the first stopper is provided, and the stoppers are connected to each other. The first stopper causes the second stopper to retract against the urging means when a water pressure of more than a set value acts on at least one of the mutually opposing contact surfaces of the safety gate. When the security gate is closed, at least one of the sides opposite to the facing contact surfaces of the stoppers is tilted, and when the security gate is closed,
A security gate device characterized in that the first stopper is inclined so that the second stopper moves back against the urging means.
