Description
Technical field
The present invention relates to a kind of boat-carrying portable high-efficiency laser radio method of electric energy transfer
Background technology
Wireless power transmission (Wireless Power Transmission) be exactly using a kind of special installation by electric energy with
Wireless is transmitted, so as to directly transmit electric energy in the case of without cable.Early in 1890, famous thing
Neo-confucian and Electrical Engineer Ni Gula teslas (Nikola Tesla) just propose wireless power transmission, and this is theoretical simultaneously
And the experiment of wireless power transmission is done.But considerably long in the period of in due to the bottleneck problem about technical elements being present, and
Lack objective demand, many researchs in terms of wireless energy transfer all do not have breakthrough.The hair of wireless power transmission technology
Exhibition is in the 60 to 70's of eighties of last century, with the protrusion of energy problem, a large amount of appearance of Small Wireless Devices and electric power electricity
The development of sub- technology makes people generate interest again to this problem.The research of wireless power transmission technology is concentrated mainly at present
Solar energy space base station, the remote bulk power transmission in ground, aircraft and the supply of satellite radio electric power, portable mobile apparatus supply
The field such as electricity, biomedical sector, the charging of transplantable mini-plant.
Remote wireless power transmission can use microwave or laser to make carrier, i.e. transmitting terminal converts electrical energy into microwave or laser
Energy is transmitted into receiving terminal, and microwave or laser are converted into electric energy by receiving terminal again, and two kinds of transmission technologys are in studying rank at present
Section.Microwave is electromagnetic wave of the wavelength between radio wave and infrared radiation, is that penetrability is good the advantages of microwave power transmission, fits
Remote transmission is closed, shortcoming is that transmitting and receiving device are huge, is not suitable for portable and transmitting, reception device are required light to set
It is standby to use.And laser power transmission is then to convert electrical energy into laser by stimulated radiation amplification first, then laser is irradiated to reception
(generally photovoltaic cell) carries out opto-electronic conversion on device.This kind of electric power distribution has long transmission distance, efficiency of transmission height, received
Device is small, is adapted to the advantages that miniaturized electronics use, in the case of emergency short of electricity, for example, in big flood or coastal
In the disaster relief of city, traffic route, electric power facility are damaged, it is necessary to emergency service, in these cases, if portable nothing
Line power transfer, is mounted on rescue ship, you can quickly and easily obtains electric energy, is given birth to for protection personal safety, production
Dexterous profit provides huge help.
The content of the invention
In view of the above-mentioned problems, the purpose of the present invention is overcome the deficiencies in the prior art, with reference to practical application, there is provided Yi Zhongchuan
Portable high-efficiency laser radio method of electric energy transfer is carried, the simple and efficient power supply of the method, there is high practical value.It is and portable
Efficient radio energy transmitting device may be mounted at optional position, can also be carried by small aircraft and serve as stand-by power supply use.
Technical scheme is as follows：
A kind of boat-carrying portable high-efficiency laser radio method of electric energy transfer, including：
(1) by the use of boat-carrying electric energy as excitation energy source, semiconductor laser is encouraged, after beam shaping, produces energy
Measure laser beam；
(2) in the receiving terminal of portable high-efficiency wireless electric energy transmission device, laser beam expander is placed in can track it is sharp
On the movable pedestal of light light beam；
(3) parallel injection after laser beam expander expands the laser beam of incidence；
(4) converge to prism via spherical reflector reflection from the laser that laser beam expander projects and project photovoltaic electric again
Pond；
(5) photovoltaic cell converts light energy into electric energy.
For the present invention due to taking above technical scheme, it has advantages below：
(1) present invention using laser be used as wireless power transmission mode, because laser direction is good, energy concentration the features such as
So that a large amount of luminous energy can concentrate on a little space scope and be received, therefore, this kind of electric power distribution has long transmission distance, transmission
Efficiency high, reception device are small, are adapted to the advantages that miniaturized electronics use, and remote power transmission tool is carried out to minute vehicle etc.
There is the application value of uniqueness.For example, using the long-range charging technique of laser, minute vehicle (Micro Air Vehicle- will be made
MAV) extension in cruising time is possibly realized.
(2) laser beam is during propagation in atmosphere, it is contemplated that the sink effect of atmospheric molecule, the scattering effect of atmospheric molecule
Should, the influence of atmospheric turbulance and big aerosol, laser beam energy can decay.Therefore beam condensing unit is needed to enter laser beam
Row optically focused.The present invention is converged to laser in high transparency prism using spherical reflector mode, then will by more node photovoltaic cells
Luminous energy is converted into electric energy.The beam condensing unit of the present invention, on the one hand, the radiosity for receiving battery chip unit area is big
Increase to amplitude, solar cell electricity conversion is improved；On the other hand, can be significantly for given power output
Degree reduces the consumption of solar battery chip, so as to reduce the cost of system.
