The open type deep sea direct-driven tide generator has the advantages that an additional aeration-cooling system is not required by the open type structure, the structure is simple, reasonable and practical, the generator is started under a low-speed tide condition and the generator can be used in deep sea.
Description
Technical field
The invention belongs to motor and power engineering equipment technical field, particularly the design field of sea tide underwater power generator, relates in particular to a kind of open type deep sea directly and drives tidal current generator.
Background technique
The energy is the important substance basis of human survival and social development.Current, the non-renewable fossil fuels such as the oil that the mankind utilize, rock gas, coal, day by day exhausted, also brought serious environmental problem.Ocean Tidal Current Energy is the energy that the tide-generating force of the moon and the sun forms while making seawater produce periodically back and forth horizontal motion, is a kind of outstanding clean reproducible energy.
World today's ocean energy exploitation has become focus, and China also just carried out the research and development of marine tidal-current energy direction before 30 years.The current domestic tidal current energy generating equipment development of carrying out, rotor machine wherein generally adopts the permagnetic synchronous motor of gear transmission internal rotor type.This mode and structural type need periodic maintenance, step-up gear difficult in maintenance owing to having adopted, and the reliability of whole trend unit is reduced; In addition, due to the efficiency of gear-driven resisting moment and transmitting torque, the start velocity of trend unit is strengthened, unit efficiency is lower, has affected marine tidal-current energy ground utilization ratio; The impact on generator electric part for fear of seawater in addition, the model machine of the unit of research and development trial-production at present all by generator arrangements in sealed compartment, thereby make the cooling problem of ventilation of generator and the sealing problem of trend unit become a difficult problem.
Summary of the invention
The invention provides a kind of Open architecture and drive tidal current generator without the open type deep sea directly of separately establishing ventilation cooling system, just can start, can use under low flow velocity trend in deep-sea.
The technical solution used in the present invention is:
Open type deep sea directly drives a tidal current generator, it is characterized in that: comprise open external rotor, described external rotor is connected with impeller, in described external rotor, is fixed with stator, and the internal surface of described external rotor and the outer surface of stator all seal to fill with and be coated with envelope filling resin.The present invention adopts open external rotor, directly by seawater, undertaken cooling, and on the internal surface of external rotor and the outer surface of stator, be equipped with envelope filling resin, can make the electric part of external rotor and the electric part of stator isolating and protecting in the seawater of 300 meters of depths.
Further, the end of described stator is provided with bearing means, and described external rotor and impeller be rotatable being arranged on bearing means all.External rotor passes to stator by bearing means by rotating load.
Further, the internal circular surfaces of described external rotor and the outer surface of stator all adopt the mode of centrifugal pressure casting to cover envelope and fill with resin.
Under the rotating magnetic field effect that stator of the present invention produces at external rotor, at inner sealing conductor, produce induction current, electric energy output.External rotor rotates under the driving of impeller, produces rotating magnetic field.Envelope filling resin covers the outer surface that the internal circular surfaces of rotor makes itself and deep sea water isolation protect and cover stator outside protects itself and deep sea water isolation.Bearing means bears the rotational load of external rotor and impeller generation and passes to stator.Impeller is caught to trend kinetic energy, passes to external rotor.Flow through stator and external rotor of seawater carries out cooling to it.
When the present invention works, external rotor is directly caught trend kinetic energy by impeller and is driven and rotate and produce rotating magnetic field, owing to not establishing other driving mechanism, does not therefore have resisting moment and the malfunctioning node of other driving mechanism, make generator start velocity be low to moderate 0.3 meter per second, efficiency and reliability are high.Under the rotating magnetic field effect producing at external rotor, the sealing conductor of stator interior will produce induction electromotive force and induction current, thereby marine tidal-current energy is converted to electric energy, reach generating object.Because adopting the mode of centrifugal pressure casting to cover envelope, stator outer surface fills with resin, the internal circular surfaces of external rotor adopts the mode of centrifugal pressure casting to cover envelope and fills with resin, after solidifying, electrical installation face is all isolated with seawater, reach the object 300 meters of deep-sea protection, do not need again seawater to be taked to seal approach, can open type be placed in seawater, the heating loss of generator directly carries out cooling by seawater.
The invention has the beneficial effects as follows: Open architecture is without separately establishing ventilation cooling system, and simple and reasonable practicality just can start under low flow velocity trend, can in deep-sea, use.
