As optimization, secondary water wheels are opposite with the blade lean direction that main water wheels absorb the water energy, sense of rotation is opposite.So design, main water wheels can be realized the purpose that sense of rotation is opposite with the shared same water channel of secondary water wheels.
As optimization, the secondary water wheels wheel that meets water before being, the main water wheels wheel that meets water after being.So design, because secondary water wheels drive secondary rotor and secondary stator two cover generating windings simultaneously, main water wheels only drive main rotor, the former load and generating capacity are obviously greater than the latter, so secondary water wheels are positioned at upstream face one end and absorb main flow energy earlier, main water wheels are positioned at downstream and absorb main current remaining secondary flow energy after secondary water wheels absorb again, have both helped giving full play to both generating capacities, again abundant trans-utilization water energy.
As optimization, the water channel that is used for hydraulic generator is rectilinear, horizontal, ramp type or bend formula, many main water wheels of group and secondary water wheels is installed successively before and after in a water channel.So design can improve waterpower utilization rate greatly.
As optimization, the water channel that is used for hydraulic generator is current two water channels in the same way arranged side by side, and many groups of main water wheels that front and back are arranged in order and secondary water wheels are installed on two water channels, and every group of master's water wheels and secondary water wheels lay respectively in the water channel of both sides.So design both can utilize two water channel generatings of current in the same way simultaneously, can realize main water wheels and the opposite purpose of secondary water wheels sense of rotation again, also can improve waterpower utilization rate greatly.
As optimization, the water channel that is used for hydraulic generator is a U type water channel, many main water wheels of group and secondary water wheels are installed on the opposite both sides water channel of the water (flow) direction of U type water channel, every group of master's water wheels and secondary water wheels lay respectively in the water channel of both sides, and secondary water wheels are identical with the blade lean direction that main water wheels absorb the water energy, sense of rotation is opposite.So design both can utilize two water channel generatings of reverse flow simultaneously, can realize main water wheels and the opposite purpose of secondary water wheels sense of rotation again, also can improve waterpower utilization rate greatly.
As optimization, staor winding connects the secondary rotor generating set of stator output circuit.So design makes things convenient for wiring.
