An Electromagnetically Engaged/Disengaged Beam for Underwater Gate Hoisting
The automatically engaged/disengaged beams widely used in water conservancy and hydropower projects can be divided into mechanical and hydraulic categories.The mechanically engaged/disengaged beam is prone to mis-opera-tions.While the hydraulically engaged/disengaged beam may cause various faults such as the beam pin shaft jamming,inadequate threading and retraction of the pins,cable breakage,and water ingress into the cables and the pump station.In response to the above problems and considering the hoisting conditions of the layered water intake stack gate in Wud-ongde Hydropower Station,a new wireless controlled electromagnetically engaged/disengaged beam is developed.In the manufacturing plant and the working site of the gate in the station,above-water and underwater gate hoisting tests and underwater sealing tests are carried out and the feasibility of the gate operation in flowing water is verified.
