Helical rotating wheel for hydroelectric generator

Abstract

The invention discloses a helical rotating wheel for a hydroelectric generator. The helical rotating wheel for the hydroelectric generator comprises journals, a shaft sleeve, a bearing bush, a bearing pedestal, channel steel, supporting legs, an outer cylinder, second bolts, an inner cylinder, square supporting frames and helical blades, wherein the helical blades are welded to the outer circle of the inner cylinder in the axial direction; the inner cylinder is freely sleeved with the outer cylinder, and the helical blades are not in contact with the inner wall of the outer cylinder; the journals are welded to the outer walls of the two ends of the inner cylinder in the axis direction; the journals are installed on the bearing pedestal through the bearing bush; the channel steel is welded to the circumference of the bearing pedestal, the number of the channel steel is three, and the three pieces of channel steel are welded to the circumference of the bearing pedestal in the left, right and up direction, and are in plane symmetry with respect to the vertical axis; one end of each piece of channel steel is fixed to the corresponding supporting leg through the corresponding second bolt; and the supporting legs are welded to the square supporting frames which are perpendicularly welded to the outer cylinder. According to the structure of the helical rotating wheel, a sealing device is omitted, assembling and disassembling are convenient, and maintenance is easy.

Description

technical field [0001] The invention relates to a helical runner hydroelectric generator, in particular to a helical runner used for the hydroelectric generator. Background technique [0002] The helical runner hydroelectric generator is a new type of micro hydroelectric power generation equipment, which has low civil construction cost, high efficiency, and environmental friendliness. In recent years, it has been more and more widely used in Europe, North America, Australia and other regions. In order to make full use of my country's low-head hydropower resources and accelerate the realization of my country's strategic goals of energy conservation and emission reduction, it is of great significance to independently develop spiral runner hydropower equipment. However, the size of the runner equipment at the end of the spiral runner is large, and the concentricity between the runner and the outer cylinder is not easy to ensure. In addition, the bearing works in a water environ...

AI Technical Summary

Problems solved by technology

However, the size of the runner equipment at the end of the spiral runner is large, and the concentricity between the runner and the outer cylinder is not easy to ensure. In addition, the bearing works in a water environment, and the lubrication, sealing and corrosion resistance of the bearing must be solved.
