Problems solved by technology

[0006] The technical problems to be solved by the present invention are as follows: 1) The transmission shaft and bearing in the existing hydroelectric power generation device have relatively large losses due to the large force and high temperature generated by friction; 2) the generator of the existing hydroelectric power generation device Exciters and exciters will generate a lot of waste heat during work, and a special cooling system needs to be installed, and the cooling effect of the cooling system is not good, and it is easy to burn the core; 3) The high stable efficiency of the existing water turbine is only about 90%; 4) The existing hydro-generators are all customized machines for different terrains, and there are large differences in volume, which cannot be mass-produced; High strength requirements

Abstract

The invention discloses an integrated reversed assembling mixed-flow type hydraulic generator which comprises an armature mechanism, an excitation mechanism, a sealing cover mechanism, a draft tube, a guide vane mechanism, a turning wheel and a volute. The volute, the guide vane mechanism, the turning wheel and the draft tube sequentially form a water flow channel; the sealing cover mechanism comprises a rotary cover and a fixed cover; the rotary cover and the fixed cover are connected through a sealing bearing to form a closed annular cavity; the armature mechanism and the excitation mechanism are coaxially installed in the annular cavity in parallel in an inner layer and outer layer mode; the excitation mechanism is installed in the rotary cover; and the armature mechanism is installed in the fixed cover. The integrated reverse assembling mixed-flow type hydraulic generator is long in service life, low in building cost and production and management cost and high in water power conversion efficiency.

Description

technical field [0001] The invention relates to the field of hydropower equipment, in particular to an integrated reverse-installation mixed-flow hydroelectric generator. 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 flow of this type of turbine is relatively sma...
