Hydraulic grab beam underwater camera WTDC type

Introduction and Application of the Hydraulic Grab Beam Underwater Camera WTDC

Model :WTDC

At present, most of the beam grab pins are still monitored and controlled based on proximity switches or inductive analog signals. Many electrical control systems are not well equipped. Even if their functions are configured, they have not fully achieved the connection of automatic detection and control, and have not realized the automatic control effect. Even some equipment only relies on the monitoring of opening load
The equipment, combined with previous records, is operated by the driver to ensure the lifting and lowering of the gate by grasping the beam.

In the actual operation process, after the grab beam is lowered into the water, the driver relies entirely on the opening degree, load, and the signal of the position detection device for judgment, and then the driver performs the operation control. But in the actual process,There are situations where the height judgment of the beam stacking door is inconsistent, the self-weight display during the beam grasping switch is inconsistent, and there are errors in the judgment of the positioning signalAt this time, when the driver is operating, in order to ensure that the grab beam lands in place, the descent depth is too large, the steel wire rope comes out of the groove and gets stuck, and there are also problems such as the grab beam not being aligned with the gate, and the signal judgment of the disengagement pin not being accurate, causing the gate to get stuck when lifting.

2. Applicable scenarios of the hydraulic grab beam underwater camera WTDC

It is mainly used in hydropower stations and the like. For instance, it has been successfully applied in hydropower stations such as Gezhouba and Xiangjiaba, and can achieve high-definition imaging even in murky underwater conditions.

7. Concluding remarks

Our company has specially developed a hydraulic grab beam visual comprehensive monitoring system based on market and customer demands. It uses real-time dynamic data and underwater visual video methods
After monitoring the normal alignment of the grab beam and the gate, the connection work between the pin and the gate is carried out. After confirming that the grab beam pin is in place under data visualization, the gate is lifted.
To ensure the safe and reliable lifting and lowering of the gate by the hydraulic grab beam during unit maintenance or cleaning.
