Abstract

The invention relates to a damping structure of a hydropower station generator layer plate beam, and belongs to the field of hydropower station buildings. The damping structure comprises a frame assembly and a damping assembly; the damping assembly comprises a base arranged on a cross beam; the base is provided with a first sliding groove and a second sliding groove; the bottom of the first sliding groove communicates with the bottom of the second sliding groove; a supporting column is in sliding connection in the first sliding groove; the upper surface of the supporting column abuts against the lower surface of a prefabricated floor slab; a first cavity is formed by the lower surface of the supporting column and the side wall of the first sliding groove; a positioning plate is fixed to the second sliding groove; a drive plate is arranged on the side, facing the second sliding groove, of the positioning plate; an elastic piece is arranged between the positioning plate and the drive plate; a second cavity is formed by the drive plate and the side wall of the second sliding groove; and the first cavity and the second cavity are filled with liquid. The damping structure has the effect of reducing the risk of stand column fatigue damage.

Description

technical field [0001] The present application relates to the field of hydropower station buildings, in particular to a shock-absorbing structure for a deck beam of a hydropower station generator. Background technique [0002] The powerhouse of a hydropower station is a comprehensive engineering facility that converts water energy into electrical energy. The main electromechanical equipment of the hydropower station is arranged together to make it have good conditions for operation, management, installation, and maintenance, including the main engine room and installation room. The unit and auxiliary equipment are arranged in the main engine room, which is the main place for operation and management. The installation room is the place used for unloading, unpacking, assembly, and maintenance of the electromechanical equipment of the hydropower station. [0003] The structure of the existing main engine room is similar to that of an industrial workshop, which is a slab, beam, ...
