Downstream ultra-low head tubular turbine power station

The invention belongs to a small power station and particularly relates to a downstream ultra-low head tubular turbine power station. A generator set is mainly composed of tail water pipelines (1), turning wheels (2), guide blades (3), speed-up gear boxes (4), generators (5), water leading pipelines (8) and the like. The ultra-low head power generation equipment is suitable for an ultra-low head of 1.5-2 meters for station construction. The tubular generator set is adopted and can be installed underneath a gate. A lot of engineering projects such as generator set foundations, water leading channels and water drainage channels are omitted, and therefore 20% construction costs can be reduced. The ultra-low head tubular turbine power station has the advantages of being capable of utilizing rich ultra-low head hydraulic resources, short in construction period, low in investment and quick in income. The small hydropower station does not need to store a lot of water, so that ecological balance will not be affected; furthermore, personnel employment in remote areas is increased, and rural economy development is promoted; besides, green energy is increased, carbon emissions are reduced, and environmental protection is facilitated.
