Water guide supporting structure of tubular unit

Abstract

The invention discloses a water guide supporting structure of a tubular unit. The water guide supporting structure comprises a main shaft, two annular bearing bodies and a supporting base, wherein the main shaft is transversely arranged, the two annular bearing bodies are matched with the main shaft in a rotating mode, and the supporting base is used for supporting the lower sides of the bearing bodies; connecting sheets are integrally arranged on the lower sides of the bearing bodies; the linear lower side edges of the connecting sheets are connected to the supporting base in a rotating mode in a rotating plane which vertically passes through the axis of the main shaft; when the matching sections of the main shaft and the bearing bodies incline in the rotating plane to form an inclination angle; the connecting sheets rotate by an adjustment angle relative to the supporting base; and in addition, the adjustment angle is matched with the inclination angle. The water guide supporting structure has the advantages that installation is convenient, the installation efficiency can be favorably improved, in addition, the fatigue resistance can be improved, loosening of bolts is avoided, and the installation quality is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic generators, in particular to a water guide support structure of a tubular unit. Background technique [0002] With the enhancement of people's awareness of energy conservation and environmental protection, clean and efficient power generation equipment is being vigorously developed, among which the tubular unit (horizontal unit) occupies an important position in my country's clean energy industry. As we know, the tubular flow unit usually includes a flow channel arranged horizontally, a bulb-shaped casing arranged in the flow channel, a main shaft is arranged in the casing, a rotor is arranged on the main shaft, a stator matched with the rotor is arranged on the inner wall of the casing, and a stator is arranged on the inner wall of the casing. The front end of the body is closed, and a runner is provided at the rear end of the housing where the main shaft extends out. When water flows through ...

AI Technical Summary

Problems solved by technology

[0004]However, this type of supporting structure has the following defects: we know that the runner near the downstream side of the water guide bearing can weigh tens to hundreds of tons, while the other side of the main shaft The rotor at one end is also of great weight

In order to ensure the smooth rotation of the main shaft after installation, the water guide bearing needs to be fine-tuned, which will affect the installation efficiency of the unit and the matching relationship between the main shaft and the water guide bearing after installation.
