Horizontal type inclined-jet outer-blade hydraulic generator easy to cool and acting method thereof

Abstract

The invention discloses a horizontal type inclined-jet outer-blade hydraulic generator easy to cool and an acting method thereof. The horizontal type inclined-jet outer-blade hydraulic generator easy to cool comprises a power generating mechanism, an excitation mechanism, an inclined-jet impeller mechanism and a rotating shaft mechanism. The inclined-jet impeller mechanism comprises inclined-jet blades, a round front hood and a round rear hood, wherein the inclined-jet blades are annularly distributed on the outer side of the round front hood, the round front hood and the round rear 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 inside-outside mode. The rotating shaft mechanism and the round rear hood are fixedly and coaxially connected. The horizontal type inclined-jet outer-blade hydraulic generator easy to cool is good in universality, long in service life, high in power generating efficiency and low in building cost and production management cost.

Description

technical field [0001] The invention relates to the field of hydroelectric equipment, in particular to a horizontal easy-to-radiate oblique-impact outer-blade hydroelectric generator and a work-acting 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 ...

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 The exciter and exciter 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 enough to easily 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, so they cannot be mass-produced; 5) Stator, rotor, salient poles, drive shafts and other components in hydro-generators have high requirements on material strength
