Horizontal type center-through reversely-installed inclined-jet hydraulic generator and acting method thereof

Abstract

The invention discloses a horizontal type center-through reversely-installed inclined-jet hydraulic generator and an acting method thereof. The horizontal type center-through reversely-installed inclined-jet hydraulic generator 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, an annular inner hood and an annular outer hood, wherein the inclined-jet blades are annularly distributed on the inner side of the annular inner hood, the annular inner hood and the annular 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 a front-back mode. The annular outer hood is fixedly mounted on a supporting table. The horizontal type center-through reversely-installed inclined-jet hydraulic generator is long in service life, low in building cost and production management cost, good in universality and high in kinetic energy converting efficiency.

Description

Technical field [0001] The invention relates to the field of hydropower equipment, and in particular to a horizontal mid-pass reverse-mounted oblique hammer type water turbine generator and a work method thereof. Background technique [0002] According to the working principle, hydraulic turbine power generation devices can be divided into two categories: impulse turbine and counterattack turbine. The runner of the impulse turbine rotates under the impact of the water flow. The pressure of the water flow does not change during the working process, which is mainly the conversion of kinetic energy; the runner of the impact turbine rotates in the water by the reaction force of the water flow, and the pressure of the water flow during the work Both energy and kinetic energy have changed, but mainly the conversion of pressure energy. [0003] The impulse turbine, because its working wheels only partially pass the water and part of the bucket is stressed, so the required flow of this ty...

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 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 enough, and it is easy to burn the core; 3) The efficiency of the existing oblique impact turbine is only 80% to 84% %, generally low; 4) Existing hydro-generators are custom-made machines for different terrains, and there are large differences in volume, which cannot be mass-produced; 5) The stator, rotor, salient pole, Components such as drive shafts require high material strength
