Description
Technical field
The present invention relates to electricity generating device, especially small-sized hydroelectric power generating apparatus.
Background technique
At present the power station in electric power system mainly contains four kinds of thermal power generation, hydroelectric power, nuclear energy power generation and generations of electricity by new energy.The fossil fuel that thermal power generation needs the natures such as coal combustion, oil, rock gas to contain, because coal, oil, rock gas etc. belong to non-renewable resources, from the energy-conserving and environment-protective angle, thermal power generation will step down from the stage of history gradually.Yet along with the development of society, need for electricity can be increasing, so each state is all trying to explore new generation mode and the generation technologies such as nuclear energy power generation, generation of electricity by new energy.
Hydroelectric power is the renewable sources of energy, and environmental pollution is little, and generating efficiency is high, and cost of electricity-generating is low, and starting and generating is fast, regulates easily, and the power cost of unit output is minimum, therefore, hydroelectric power be comparatively clean at present, safety, efficient generation mode.Present hydroelectric power station all needs barrage to build a dam, and forms the water-head between upstream and downstream, utilizes the potential energy of water to be converted into the rotation of kinetic energy promotion water turbine, and then drives the generator set generating.Although the river of China distributes a lot, what suitable barrage was built a dam is local and few, and waterpower resourses do not obtain general effective the utilization.
Summary of the invention
The purpose of this invention is to provide a kind ofly not affecting under the current prerequisite in normal navigation channel, be adapted at the floating hydroelectric generator of laying to generate electricity in most of sections.
For realizing above-mentioned technical purpose, floating hydroelectric generator of the present invention, include ship shape generation platform, water turbine, variable-speed motor and generator, the ship shape generation platform floats on the riverbed water surface with certain water velocity, water turbine is installed on the bottom of ship shape generation platform, the base plate that the output shaft of water turbine is upward through the ship shape generation platform is connected with the input shaft of variable-speed motor on being fixed on the ship shape generation platform, the output shaft of variable-speed motor is connected with the rotor shaft of generator, accesses national grid after the electricity process transformer transformation of generator output.
Current are during through the water turbine under the ship shape generation platform, the impeller blade that the water impact water turbine of certain speed is arranged drives water wheel axle and rotates, and the input shaft that water wheel axle drives variable-speed motor rotates, rotate through the rotor that drives generator after the variable-speed motor speed change, thereby realize generating.Under the prerequisite that does not affect normal navigation, the present invention can be arranged on any riverbed water surface with certain flow rate, the ship shape generation platform can according to the environmental conditions of use occasion do do greatly little, if the ship shape generation platform is larger, can on same ship shape generation platform, a plurality of water turbine, variable-speed motor and generator be set, form generator set; A plurality of water turbine perhaps are set under same ship shape generation platform drive a generator, concentrate again the access national grid after generating electricity by way of merging two or more grid systems.
Water turbine can have the various structures form, such as the impeller shaft that adopts water turbine vertically arranges, is distributed with impact type arc impeller blade on impeller shaft, and whole water turbine is arranged in the shell that circumferentially is semi-surrounding by bearing; Perhaps adopt impeller shaft to be horizontally disposed with, water turbine is tubular turbine, and the impeller shaft of water turbine turns to the input shaft of rear and variable-speed motor to realize the moment transmission by transaxle.
The present invention invests little, instant effect, easy to implement, under the prerequisite that does not affect normal navigation, can be arranged on any riverbed water surface with certain flow rate, take care of the pence, also can obtain a large amount of electric energy, the river water resources that China is a large amount of fully utilize, and solve the realistic problem of electric power resource shortage.
