Pipeline connecting structure of hydroelectric generating set

The utility model provides a pipeline connecting structure of a hydroelectric generating set, which relates to the technical field of pipeline connection and comprises a bottom plate, a pipeline frame, an auxiliary column, a suspender, a two-way pipe and a three-way pipe, the outer side of the pipeline frame is movably connected with an auxiliary supporting mechanism, and a rotary adjusting mechanism is fixedly mounted in the pipeline frame. The servo motor is started, the servo motor drives the gear to rotate, the outer gear ring meshed on the outer side of the gear obtains power and drives the annular plate to move, the two sides of the annular plate are movably clamped on the outer side of the first side plate and the outer side of the second side plate respectively, so that the annular plate rotates, friction force exists between the two-way pipe and the annular plate and between the three-way pipe and the annular plate, and the two-way pipe and the three-way pipe are separated. The annular plate rotates
