Weight balancing method for ship reception chamber and counterweight system of ship lift

The invention discloses a weight balancing method for a ship reception chamber and a counterweight system of a ship lift. The method comprises the following steps: S1, determining a proportionality coefficient between a driving motor operation torque and a driving load of a ship lift chamber driving system; s2, determining the rated water depth of the ship reception chamber during operation of the ship lift; s3, the ship reception chamber runs upwards under the rated water depth, and the running torque of the driving motor is recorded; s4, the ship reception chamber runs downwards at the rated water depth, and the running torque of the driving motor is recorded; s5, calculating a difference value between the weight of the ship reception chamber and the weight of the counterweight system at the rated water depth according to the recorded operation torque of the driving motor for the up-down operation of the ship reception chamber; and S6, adjusting the weight of the counterweight system according to the differ
