Gates are installed at water intake gates and sewerage settling basin entrances and exits, and in the event of a natural disaster or unforeseen situation such as an earthquake, heavy rain, or power outage, waterways can be shut off in an emergency to secure drinking water and prevent secondary disasters. prevention and protection of facilities. For this reason, the gate is equipped with a self-weight-lowering type opening/closing device. That is, although not shown, an opening/closing device consisting of an electric motor, a reduction gear, an electromagnetic clutch, a lowering device, etc. is arranged in a series directly above the gate. Since the electromagnetic clutch used an inverted clutch type, in which the clutch action works without energization, that is, it is in a state where power can be transmitted when the power is not energized, in the event of an emergency or a power outage, the gate will lower under its own weight. Since it is not possible to do so, the gate opening/closing machine was provided with a direct current power source such as a battery.
