Shock absorption unit special for hydropower station

Abstract

The invention relates to a shock absorption unit special for a hydropower station. The shock absorption unit comprises a bottom plate. Two unit bodies which are connected with each other are mounted at the upper end of the bottom plate. Four shock absorption branch chains are symmetrically arranged on the lower end face of the bottom plate and mounted on a mounting plate. Four lower limiting columns are symmetrically welded to the lower end of the bottom plate and connected with the mounting plate through lower limiting springs. Two upper limiting columns are symmetrically welded to the two sides of the middle portion of the mounting plate. All the upper limiting columns are connected with the bottom plate through upper limiting springs. Each shock absorption branch chain comprises a substrate welded to the lower end face of the bottom plate. Two upper lug seats are symmetrically welded to the two ends of each substrate. Each upper lug seat is connected with the top end of a first extending-and-contracting rod through a pin shaft. The bottom end of each first extending-and-contracting rod is connected with a lower lug seat through a pin shaft. Each lower lug seat is obliquely welded to a mounting block. The shock absorption unit special for the hydropower station can achieve the good shock absorption effect and has the beneficial effects that the structure is simple, the shock absorption effect is good, and vibration noise is small.

Description

Technical field [0001] The invention relates to the technical field of hydropower station equipment, in particular to a special shock absorption unit for hydropower station. Background technique [0002] A hydropower station is a comprehensive engineering facility that converts water energy into electric energy. It includes a series of hydroelectric power station buildings and various hydroelectric power station equipment built by using water energy to produce electricity; these buildings are used to concentrate the drop of natural water flow to form a water head and gather , Regulate the flow of natural water flow, and send it to the water turbine. Through the combined operation of the water turbine and the generator set, the concentrated water energy is converted into electrical energy, and then the electrical energy is input into the grid through transformers, switch stations and transmission lines. [0003] Because the water pressure formed by the water drop is relatively large...
