A small integrated hydroelectric generator set

Abstract

The invention discloses a small-size integrated water turbine generator set. The small-size integrated water turbine generator set comprises a flow guide mechanism, a rotating wheel chamber, a rotating wheel, a water turbine rotary shaft, a siphoning type tail water pipe and a generator, wherein the bottom of the rotating wheel chamber is fixedly connected with the flow guide mechanism; the top of the rotating wheel chamber is fixedly connected with the siphoning type tail water pipe; the generator is arranged at the top of the siphoning type tail water pipe; the rotating wheel is reversely mounted in the rotating wheel chamber; the rotating wheel comprises a wheel hub and a plurality of rotating wheel blades; the bottom of the wheel hub is connected with the flow guide mechanism and the top of the wheel hub is fixedly connected with the water turbine rotary shaft; the top of the water turbine rotary shaft is fixedly connected with a main shaft of the generator; each rotating wheel blade is formed through fitting five different wing forms at parts with space sections Span of 0, 0.2, 0.50, 0.75 and 1.0 respectively. With the adoption of the structure, a flow state of water flow can be guaranteed very well; the siphoning type tail water pipe is adopted so that unnecessary civil engineering investment can be reduced and construction investment of factories is avoided. Furthermore, the small-size integrated water turbine generator set is simple in structure, relatively small in size and convenient to mount, and ultralow water head resources can be effectively utilized.

Description

technical field [0001] The invention relates to a small-scale ultra-low head hydraulic renewable energy power generation integrated water turbine generator, which belongs to the technical field of fluid machinery and hydropower engineering equipment; in particular, it is a small integrated water turbine generator set. Background technique [0002] Hydropower resources are clean and renewable energy. Although my country has relatively rich water resources, the development of medium and high water head resources is often accompanied by high development costs, including compensation for inundation losses and resettlement demolition compensation. Resources have also been gradually exhausted, so the development of ultra-low head power stations has become a mainstream trend. my country's low-head hydraulic resources are mainly distributed in densely populated and economically developed areas such as southeast my country. The construction of low-water-head power stations has the ad...

Problems solved by technology

[0003] The draft tube of the traditional power station usually adopts the elbow type, and the straight cone draft tube is mainly used for the low head power station. These two kinds of draft tubes belong to the configuration method of placing the draft tube under the draft tube, which is often accompanied by a large amount of civil excavation. With a large initial investment, it is difficult to use these two draft tubes due to space and capital constraints when developing an ultra-low head power station
