Suspension type efficient excitation flush inclined-jet hydraulic generator and acting method thereof

Abstract

The invention discloses a suspension type efficient excitation flush inclined-jet hydraulic generator and an acting method thereof. The suspension type efficient excitation flush inclined-jet hydraulic generator comprises a power generating mechanism, an excitation mechanism, an inclined-jet impeller mechanism and a rotary shaft mechanism. The inclined-jet impeller mechanism comprises inclined-jet blades, an annular inner cover and an annular outer cover. The inclined-jet blades are circularly distributed on the outer side of the annular outer cover. The annular outer cover and the annular inner cover are connected through a sealing bearing to form a sealed annular cavity. The power generating mechanism and the excitation mechanism are coaxially installed in the annular cavity in an inside-outside mode side by side. The rotary shaft mechanism and the annular inner cover are coaxially and fixedly connected. The upper portion of the annular inner cover is fixed to a suspension tubular arm. The suspension type efficient excitation flush inclined-jet hydraulic generator is good in universality, long in service life, high in power generation efficiency and low in construction cost and production and management cost.

Description

technical field [0001] The invention relates to the field of hydropower equipment, in particular to a suspension type high-efficiency excitation flat-mounted oblique impact type 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 t...

AI Technical Summary

Problems solved by technology

[0008] 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 Exciter and exciter will produce a lot of waste heat during work, need to install a special cooling system, and the cooling effect of the cooling system is not good, easy to burn the core; 3) the efficiency of the existing oblique impact turbine is low; 4) the current Some hydro-generators are custom-made machines for different terrains, and there are large differences in volume, which cannot be mass-produced; 5) Stator, rotor, salient poles, drive shafts and other components in hydro-generators have high requirements on material strength ; 6) The utilization efficiency of the excitation magnetic field is low
