Abstract

The present invention discloses a through flow type unit water guide mechanism. It includes the following several portions: guide blade, guide blade lower shaft, guide blade arm, sleeve, connecting plate, shearing pin, control ring and internal and external water distribution rings. Said invention also provides the concrete structure of the above-mentioned every portion, and the working principle of said through flow type unit water guide mechanism.

Description

technical field [0001] The invention relates to a water guiding mechanism of a tubular unit. Background technique [0002] With the development of low-head hydropower stations, tubular turbines have been used more and more widely. At present, the water guide structure of most tubular turbines has disadvantages such as large hydraulic loss, poor water sealing effect, and low efficiency, which affect the popularization and application of tubular turbines. Contents of the invention [0003] The purpose of the present invention is to provide a new type of water guiding mechanism for a tubular unit, which not only ensures that when the water guiding structure is opened, the guide vane can rotate flexibly, has a large flow rate, and has good water guiding performance, but also ensures that when the water guiding structure is closed, the guide vane The meshing surfaces at both ends have good water sealing performance. [0004] The technical solution adopted in the present inven...
