Description
Technical field
The present invention relates to fluid and thermal machine, especially relate to a kind of mixed power machinery of inputting various energy resources.
Background technique
Various motors are products of civilization of human society, and it has become the indispensable machinery of current social development.Therefore, people have developed the motor that utilizes the various energy, and the motor of various structures is mainly the thermal expansion energy that utilizes the various energy, kinetic energy, potential energy, pressure energy etc., certainly, and the also favourable motor with electromagnetic energy.These motors can probably can be divided into following two classes by source category from its utilization: a class is to utilize the motor of fossil energy, comprise various internal-combustion engines that everybody knows, steam turbine, reaction turbine etc., these all belong to heat engine, being based upon on Thermodynamic Basis, is all to consume the motor that fossil energy is master.First kind motor is stable, good environmental adaptability, mobility is good, controllability is good, volume is relatively little.Although people have developed the heat engine of various energy-conserving and environment-protective, this class heat engine still exists certain destructive to environment, and particularly fossil energy can move towards exhausted, and the production of human future and democratic meeting formation are threatened greatly.Equations of The Second Kind is the motor that utilizes renewable energy sources, comprises various wind turbines that everybody knows, water current turbine etc., and we can be called cold machine, is all that to consume renewable energy sources be main motor.Although Equations of The Second Kind motor is less on the impact of environment, the energy consuming is renewable, but because its energy utilizing mostly exists wave properties, randomness and thin property, make that output stability is poor, utilization ratio is low, volume is relatively huge, one-time investment is large, utilize cost high, can only be arranged on the shortcomings such as place that have certain renewable energy sources.The energy kind of utilizing from above two class motors is analyzed, and we can find, which kind of motor is all the motor of the corresponding a kind of structure of the energy of a kind, and is all independent operating.
Press used energy grade, available engine can be divided three classes: a class is the high-grade energy motor that utilizes High Temperature High Pressure to flow, for example: fuel oil, gas engine, turbojet, steam turbine etc., these motors both can utilize fossil energy, also can utilize part renewable energy sources, as biomass energy.Two classes are the middle grade enegy source engines that utilize medium temperature and medium pressure to flow, such as: expansion motive power machine, water turbine, oil hydraulic motor, pneumatic motor etc.Three classes are the low-grade energy source engines that utilize low-temp low-pressure to flow, such as: wind turbine, heat energy wind turbine, ocean current turbo machine etc.Above-mentioned motor is the corresponding class motor of the energy of a grade.In addition, in utilizing low-grade energy source engine machine, due to the existence of mechanical stiction, inertial resistance, fluid resistance, make to be difficult to start compared with a hour motor when the density that can flow, the energy of low-grade energy stream can not be utilized effectively.People have taked various ways to address the above problem for this reason, and (1) utilizes magnetic suspension bearing technology to eliminate surface friction drag, have effectively reduced and have started required energy intensity of flow, have improved the output capability of turbo machine.But inertial resistance when magnetic suspension bearing cannot be eliminated engine start and fluid resistance, the startup energy intensity of flow that therefore can reduce is limited.(2) improve electric generator structure, as: by straight trough type, make the grooved of generator into chute type, but effect is not fairly obvious.(3) motor run pattern, for example: Chinese Patent Application No. is 201020044819.5 disclosed a kind of continuous running wind-driven generators for low wind speed, main generator is coaxial with motor, during low wind speed, motor drives main generator to start and moves to rated speed, when wind speed is large, wind wheel drives main generator generating, and motor also runs on generating state simultaneously.And for example: Chinese Patent Application No. is 201010270584.6 a kind of disclosed methods that realize low-wind speed startup of permanent magnet wind turbine generator, first generator set makes full power convertor in dragging mode of operation under low wind friction velocity, from electrical network, absorb electric energy, make generator operation until reach incision rotating speed, full power convertor is just converted to generating operating mode afterwards.But this mode is all to utilize the electric energy of electrical network, can not utilize the other forms of energy.
