The method can be summarized as follows: when the gate is closed, the gate leaf 1 is in a vertical state; when the gate is opened and water is discharged, the gravity and the water pressure of the gate leaf 1 can push the gate leaf 1 to rotate clockwise, and then the spring device rotates along with the gate leaf 1 to store energy; the gravity and the water pressure of the door leaf 1 form active torque to the torque of the bottom shaft 5, the torque of the spring device and the torque of the hydraulic hoist 6 form reverse torque with the small friction torque of the bottom shaft 5 and the lock chamber, and the reverse torque is equal to the active torque in magnitude and opposite in direction; if the spring device is not arranged during opening, the driving torque is unchanged, the hydraulic hoist 6 only provides reverse torque, and the torque required by the hydraulic hoist 6 when the spring device is arranged is much smaller than that when the spring device is not arranged;
when the door leaf 1 rotates clockwise to a certain position to be kept, and the door leaf 1 needs to be closed after water is discharged for a period of time, the hydraulic hoist 6 and the spring device provide active torque together at the moment so that the door leaf 1 rotates in the closing direction; when the gate is closed, the hydraulic hoist 6 and the spring device provide active torque, the water pressure and the gravity of the gate leaf 1, the friction torque of the bottom shaft 5 and the gate chamber provide reverse torque, and the active torque and the reverse torque are equal in size; compared with the hydraulic hoist 6 without a spring device, the hydraulic hoist 6 can independently provide active torque, and the torque provided by the hydraulic hoist 6 is much smaller, so that the torsion force required by the hydraulic hoist 6 when the brake is closed can be reduced;
further, referring specifically to fig. 4 (torque diagram of the bottom shaft 5), a torque diagram is drawn by taking the rotation water discharge condition of the door leaf 1 as an example, the torque T is taken as an ordinate axis, and the length X of the bottom shaft 5 is taken as an abscissa axis to respectively establish a diagram of the bottom shaft 5 torque without the spring device and a diagram of the bottom shaft 5 torque with the spring device; further, as can be seen from fig. 4:
under the condition that the reverse torque is equal under the opening working condition, the torque of the steel dam gate hydraulic hoist 6 with the spring device is obviously smaller than the torque of the hydraulic hoist 6 without the spring device; the maximum torque of the bottom shaft 6 with the spring device is obviously smaller than the maximum torque of the spring device, and the same is true under the condition of closing the gate; the size of the hydraulic hoist 6 is positively correlated with the torque provided by the hydraulic hoist 6, the torque of the hydraulic hoist 6 can be reduced, the specifications of equipment required by the hydraulic hoist 6, the bottom shaft 5 and the like can be effectively reduced, the maximum torque of the bottom shaft 5 can be reduced, the diameter of the bottom shaft 5 can be reduced, the construction and the installation are convenient, and meanwhile, the construction work amount is reduced;
namely, the spring device can provide partial torsion force for the bottom shaft 5 and the hydraulic hoist 6, so that the torsion force required by the hydraulic hoist 6 when opening the gate is reduced, and the stress of the bottom shaft 5 is optimized, thereby effectively reducing the specification or engineering quantity of equipment required by the hydraulic hoist 6, the bottom shaft 5 and the like, and further reducing the construction time and cost.
