The underwater monitoring equipment 10 arranged at the downstream of the lock chamber discovers the activity information of the migration fish, and under the action of the water pressure thrust, the water flow in the gate structure is discharged to the downstream through the hanging piece 1-1 at the downstream side, so that the flow speed generates fine fluctuation, and the migration fish generates stress reaction to the flow speed and gathers before the downstream lock chamber; at the moment, the upper turntable 4-1 is driven to rotate, so that the gate structure is driven to rotate, the migratory fish moves along with the gate rotation under the influence of the gate rotation to the gate chamber, and reaches the upstream of a river-blocking building, and the fish passing process is completed;
4. water retaining condition:
As shown in fig. 16, when a river-blocking building has a need for water from a river-blocking building: the gate part is positioned in the gate chamber and drives the upper turntable 4-1 to rotate, so that the gate part is driven to rotate to enable the radial gate 1 to be in a water blocking state, at the moment, the upstream water level is higher than the downstream water level, the water pressure can generate acting force on the radial gate 1, and the hanging piece 1-1 on the upstream side is tightly attached to the cross rod 1-2 of the radial gate 1 under the action of the water pressure, so that the water blocking effect is achieved.
5. Overhauling working conditions:
as shown in fig. 17, when the sluice structure has a service requirement: the service gate 12 is closed and water within the sluice chamber is drained for service.
