Preferably, centre bit of the lower end of first gap and second gap with the water conservancy turbine
It is identical to set height.
Effect of the invention is that：
1, pass through the first power generation chamber of setting and the second power generation chamber so that water flow dynamic energy is more completely converted into electric energy, right
Its energy is more fully utilized, and at the same time, when water velocity is larger（Flow velocity is very fast）, avoid conventional only one
Impeller rotation velocity soon damages the acceleration of the related easily worn part such as bearing, gear very much when a power generation chamber.By being rationally arranged
The water level control block in the intracavitary that generates electricity portion, horizontal plane is controlled substantially in turbine center, when water bigger, passes through two
The gap of side flows out, in the case where not reducing flow energy, be transferred into the second power generation chamber, utilize the second impeller
Continue generating operation, not only avoids the damage of easily worn part, but also do not cause the loss of the water conservancy energy.
2, by the setting to the first impeller overall material, setting high strength steel in inside wraps up high intensity in its outer surface
Rubber, and entire surface is provided with appearance shape rubber.Internal high strength steel ensure that the intensity of impeller, outer surface it is high-strength
Degree rubber ensure that the elasticity of impeller is delayed when larger speed flow flows through by the elasticity of high-strength rubber
Impact to impeller, to ensure that the stability of wheel rotation.And by being provided with villous rubber in impeller surface,
Flow has been broken up in microcosmic point, its flow direction has been adjusted, it is non-during wheel rotation to substantially reduce
The pressure of rotation direction（Substantially reduce the vibrations of impeller）, to also significantly reduce impeller and impeller axle contact position
Loss.
Due to specific purposes, must need to carry out purposes adaptability to the material of high strength steel and high-strength rubber
Transformation.Pass through the change to high strength steel constituent content so that it realizes the lighting to a certain extent of steel, but logical
The adjustment to Ti constituent contents is crossed, coordinates the adjustment of Cr, Mo, C content so that TiC hardening constituents in the high strength steel microstructure
It is finer and closely woven, to ensure that its intensity in the case of lighting.By the improvement to high-strength rubber material, especially its
Middle main rubber is set as natural rubber and vinylsiloxane rubber, coordinates the reasonable set of white carbon and zinc oxide content so that
The high-strength rubber surface elasticity is strengthened, and since the villous rubber strip material in its surface is also the high intensity rubber
Glue, therefore its resilience is also adapted to the application of the villiform rubber strip, ensure that its resilience and intensity.
Also be improved by the material of copper wire so that its while stopping sundries also to water part harmful substance into
Row absorption, to reach further purifying water effect, to reduce its erosion to the intracavitary component that generates electricity.
3, by being set as wide-mouth structure to inlet of culvert so that enter the water of culvert more than the water in culvert, thus
Part improves flow rate of water flow.And the present invention is by being configured with the first power generation chamber internal structure so that water velocity again it is big not yet
The defect that wheel speed can be caused excessively high, therefore by the way that above-mentioned culvert structure is arranged so that the water velocity for entering water is improved,
To improve generated energy.
