This application relates to the field of water conservancy engineering, in particular to a hydraulically driven movable dam mechanical dam lowering device without a power source, including a fuel tank, an oil inlet pipeline, an emergency pressure relief pipeline, a shut-off valve for the emergency pressure relief pipeline, a water accumulation container and One end of the overflow water pipeline, the oil inlet pipeline and the emergency pressure relief pipeline leads to the fuel tank, and the other end of the oil inlet pipeline and the emergency pressure relief pipeline is used to connect with the oil cylinder of the hydraulic drive movable dam; the emergency pressure relief pipeline The stop valve is set on the emergency pressure relief pipeline. One end of the overflow water pipeline is located above the water accumulation container, and the other end of the overflow water pipeline extends into the river. connected, and the water accumulation container can drive the wrench to move by gravity after the water accumulation, and open the stop valve of the emergency pressure relief pipeline. The hydraulically driven movable dam mechanical non-power source dam lowering device provided by the application can realize the mechanical non-power dam lowering device when a flood occurs, ensuring the safety of the upper reaches of the river course.
Description
technical field [0001] The present application relates to the field of water conservancy engineering, in particular to a hydraulically driven movable dam mechanical type dam lowering device without a power source. Background technique [0002] Hydraulically driven movable dams used in water conservancy projects generally need to be driven by power generated by hydraulic pressure. In the related art, the hydraulic flow generally needs to provide a power source through a motor, an oil pump, and the like. In some remote mountainous areas, due to remoteness and lack of electricity, even urban rivers often have no one on duty during the flood season. [0003] When floods occur, if the hydraulically driven movable dams in these areas are not lowered in time, it is very likely to endanger the safety of the upper reaches of the river. Contents of the invention [0004] The present application provides a hydraulically driven movable dam mechanical non-power source dam lowering de...
