The intelligent automatic control system of the mechanical grille of the hydropower station applies the principle of the frequency converter to improve the high efficiency of the cleaning machine and the reliability of the lifting. The gate crane of the hydropower station is mainly used to hoist the water conservancy gate. The hoisting net weight is large and the hoisting speed is relatively slow. The traditional cleaning machine gate hoist is hoisted with the help of the door hoisting organization. The cleaning machine cycle time is generally more than 30 minutes, and the cleaning machine is highly efficient and extremely low. After adding the lifting mechanism controlled by DC variable frequency modulation, the speed of the lifting mechanism can be changed anytime and anywhere according to the need, which further improves the high efficiency of the cleaning machine. The BICO technology, which is a very soft starter, can complete the braking system when the motor torque is created by the lifting motor when lifting, and when parking, the motor causes the braking system torque and the braking system is closed again after the braking system. In this way, there is no slip hook for the lifting mechanism, and the damage of the braking system is also reduced, and the reliability of the lifting mechanism is improved.

Decontamination machine video monitoring system: The video monitoring system is composed of PLC and mobile touch screen. Move the keys on the touch screen to send out commands, and the PLC performs logical operation of the system software; in addition, the PLC will collect the data signal of the lifting aspect ratio, the real-time operating load, the working pressure of the hydraulic transmission system, and the gate opening and closing according to the analog input. The data information such as the opening and closing angle of the machine is sent to the mobile touch screen to display the information to complete the real-time data supervision.
