Abstract

The invention discloses a vertical type center-through forward-installed rotary-paddle axial flow hydraulic generator and an acting method thereof. The vertical type center-through forward-installed rotary-paddle axial flow hydraulic generator comprises a power generating mechanism, an excitation mechanism, a rotating wheel mechanism, a draft tube, a water guiding mechanism and a rotating wheel chamber. The rotating wheel mechanism comprises rotating blades, a rotary inner hood and a fixed outer hood, wherein the rotating blades are distributed on the inner side of the rotary inner hood in a sector shape, the rotary inner hood and the fixed outer hood are connected through a sealing bearing to form a sealed annular cavity, and the power generating mechanism and the excitation mechanism are coaxially mounted in the annular cavity in parallel in an up-down mode. A closed water flow channel is formed by the water guiding mechanism, the rotating wheel chamber and the draft tube. The vertical type center-through forward-installed rotary-paddle axial flow hydraulic generator is long in service life, low in building cost and production management cost and high in water energy converting efficiency.

Description

technical field [0001] The invention relates to the field of hydropower equipment, in particular to a vertical center-pass positive-mounted paddle-rotating axial-flow hydroelectric generator and a work method thereof. Background technique [0002] According to the working principle, hydroelectric power generation devices can be divided into two categories: impact turbines and impact turbines. The runner of the impact turbine is impacted by the water flow and rotates, and the pressure of the water flow remains unchanged during the working process, mainly due to the conversion of kinetic energy; the runner of the impact turbine is rotated by the reaction force of the water flow, and the pressure of the water flow during the working process Both energy and kinetic energy are changed, but mainly the conversion of pressure energy. [0003] Pelton turbines, because only part of the working wheels pass through the water, and part of the water bucket is under force, so the required...
