Background technique
Electric energy is one of topmost energy of modern society.Generator is the machinery that other forms of energy conversion is become electric energy; It is driven by water turbine, steam turbine, diesel engine or other dynamic power machines, with current, and air-flow; The Conversion of energy of fuel combustion is that mechanical energy is passed to generator, converts electric energy into by generator again.Generator is in industrial and agricultural production, and national defence has been widely used in science and technology and the daily life.Along with the fast development of modern economy, human demand for electricity increases rapidly, and China's some areas power cuts to limit consumption situation is serious at present, and some local appearance lack coal and shut down phenomenon, and how to address this problem is worth our thinking.The subject matter that existing hydroelectric generator exists: the one, under the effect of waterpower, rotate the rotor rotation that drives generator through water wheels, cutting magnetic line produces electric current between rotor and stator, and this generation mode can only be by the rotor rotation of generator; The 2nd, waste water resource, a lot of at present areas lack water resources; The 3rd, do not reach utilization of resources maximizing the benefits, under similarity condition, let hydroelectric generator send more electricity, reach utilization of resources maximizing the benefits.
Summary of the invention
For solving existing hydroelectric generator, can only be by the rotor rotation of generator, waste water resource does not reach utilization of resources maximizing the benefits problem.The utility model provides bilobed wheel rotation hydroelectric generator, is made up of generator amature impeller, generator unit stator impeller, rotor bearing, stator bearing, rotor, stator etc.When current process generator amature impeller and stator impeller, rotate according to the direction of impeller separately simultaneously, drive rotor and stator and do the opposite direction rotation, cutting magnetic line generation electric current between rotor and stator.Bilobed wheel rotation hydroelectric generator improves running speed and increases generated energy relatively by the independent generator rotated of rotor.
The utility model solves the technological scheme that its technical problem adopted.Bilobed wheel rotation hydroelectric generator is by the stator impeller intake; Total water inlet; The impeller of rotor water intake; The impeller of rotor water outlet; Impeller of rotor; Impeller of rotor and stator impeller isolation device; Total water outlet; The stator impeller; Stator impeller water outlet; The current outer tube; Generator lower support A bearer ring; The rotor connection bearing; The stator connection bearing; Generator lower support A bearer ring and B bearing fixing device; Generator casing; Generator unit stator; Generator amature; Generator upper support B bearer ring; Generator upper support A bearer ring and B bearing fixing device; Generator upper support A bearer ring; Generator amature bearing and stator axis carrier ring; Compositions such as generator amature bearing and stator axis carrier ring fixing device.
Under identical flow condition, in order to increase the generated energy of generator, have only through improving the rotating speed of generator amature, could increase the generated energy of generator.The rotor and the stator of generator are made as and can rotate; And require rotor and stator to rotate in the opposite direction; Generator with power; Under the same conditions, bilobed wheel rotates rotor, each half turn electricity of stator of hydroelectric generator and rotates a circle electricity by the independent generator rotated of rotor and equates.The rotor of bilobed wheel rotation hydroelectric generator and stator be all speed rotations in the opposite direction simultaneously, are equaled to improve the rotating speed of generator relatively by the independent generator rotated of rotor, thereby improve the generated energy of generator.The rotor of generator is connected with rotor connection bearing, impeller of rotor, is convenient to impeller of rotor and drives the generator amature rotation through the rotor connection bearing.The stator of generator is connected with stator connection bearing, stator impeller, is convenient to the stator impeller and drives the generator unit stator rotation through the stator connection bearing.Being connected and supporting by two and partly forms of the rotor of generator and stator, some is connected with B bearing fixing device by generator lower support A bearer ring, generator lower support B bearer ring, generator lower support A bearer ring and supports; Another partly is connected with B bearing fixing device by generator upper support A bearer ring, generator upper support B bearer ring, generator upper support A bearer ring and supports.Generator amature bearing and stator axis carrier ring fixing device are used for fixing generator amature bearing and stator axis carrier ring.Generator casing is used for installing and protecting generator unit stator, generator amature, and links to each other with B bearing fixing device with generator upper support A bearer ring with B bearing fixing device with generator lower support A bearer ring.With impeller of rotor, stator impeller isolation device impeller of rotor, stator impeller are separated in the current outer tube, impeller of rotor is opposite with the stator impeller blade, is convenient to impeller of rotor and stator impeller and rotates by opposite direction.
After current get into total water inlet, under the guiding of impeller of rotor, stator impeller isolation device, current are split into two partly; Part current get into the stator impeller intake; The stator impeller of flowing through flows into total water outlet from stator impeller water outlet, and current through the stator impeller simultaneously; Under the impact of current; The stator impeller moves in the direction of the clock, because the stator impeller interconnects through stator connection bearing and generator unit stator, drives generator unit stator during the stator wheel rotation and moves in the direction of the clock; Another part current get into the impeller of rotor water intake; The impeller of rotor of flowing through flows into total water outlet from the impeller of rotor water outlet, and current are through impeller of rotor the time; Under the impact of current; Impeller of rotor because impeller of rotor interconnects through rotor connection bearing and generator amature, drives generator amature by counterclockwise rotating by counterclockwise rotating when impeller of rotor rotates.Under the effect of current, the rotor of generator and stator be all speed rotations in the opposite direction simultaneously, and cutting magnetic line produces electric current between rotor and stator.
The beneficial effect of the utility model is: adopt bilobed wheel rotation hydroelectric generator, press opposite direction through impeller drive rotor and stator and rotate, cutting magnetic line produces electric current between rotor and stator.Advantage such as pollution-free, that cost is low, generated energy is big.Be applicable to hydroelectric power.
