Description
Technical field
The present invention relates to a kind of aerial charging platform of wireless power transmission.
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 there are the bottleneck problem in relation to technical elements, 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
Microwave or laser are converted into electric energy by energy transmitting again to receiving terminal, receiving terminal, and two kinds of transmission technologys are in research rank at present
Section.The advantages of microwave is electromagnetic wave of the wavelength between radio wave and infrared radiation, microwave power transmission is that penetrability is good, is fitted
Remote transmission is closed, shortcoming is that transmitting and receiving device are huge, is not suitable for portable and requires light set to transmitting, reception device
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, receives
Device is small, is adapted to the advantages that miniaturized electronics use, and remote power transmission is carried out to minute vehicle etc., and there is uniqueness to answer
With value.
The common size of minute vehicle is only more than ten centimetres or so, can carry out the bat of dynamic video and still image
Take the photograph, biochemical detection, Traffic monitoring, communication relay, the condition of a disaster prospecting and the unique job rescued the hostages etc., therefore in industrial, business
Industry and military field are widely used demand.But the problem commonly encountered at present during miniplane use has been fly weight
Contradiction between amount, limit and cruising ability.Laser is used to carry out long distance wireless energy transmission (Wireless Power for carrier
Transmission), to the real-time electric energy supplement of miniplane, it appears that be an other admissible approach.
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 Zhongwu
Line electric energy transmits aerial charging platform, and the radio energy charging platform for carrying laser beam expander is mountable to optional position,
Stand-by power supply is served as small aircraft or other charging units, and convenient service is provided.Technical scheme is as follows：
A kind of aerial charging platform of wireless power transmission, for carrying out wireless charging to aircraft, it is characterised in that including
Laser beam expander, aluminium fin heat sink, photovoltaic cell, prism and parabolic mirror surface, wherein, laser beam expander is placed in removable bottom
On seat, laser beam can be tracked, and parallel injection after incident laser beam is expanded；Swash from what laser beam expander projected
Light converges to prism via parabolic mirror surface reflection and projects photovoltaic cell again, and photovoltaic cell is radiated by aluminium fin heat sink；Photovoltaic
Battery is used to convert light energy into electric energy.
Due to taking above technical scheme, it has the following advantages the present invention：
(1) present invention using laser be used as wireless power transmission mode, since 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
It is efficient, reception device is small, be adapted to miniaturized electronics use the advantages that, to minute vehicle etc. carry out remote power transmission tool
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 need beam condensing unit by laser beam into
Row optically focused.The present invention is converged to laser in high transparency prism using parabolic mirror surface mode, then by more node photovoltaic cells by light
Electric energy can be converted into.The beam condensing unit of the present invention, on the one hand, make the radiosity that battery chip unit area receives significantly
The increase of degree ground, solar cell electricity conversion are improved；On the other hand, can be significantly for given output power
The consumption of solar battery chip is reduced, so as to reduce the cost of system.
Brief description of the drawings
A kind of structure diagram of the aerial charging platform of wireless power transmission of Fig. 1 present invention.
The reference numerals are as follows：1 excitation energy source；2 808nm fiber coupled laser diodes；3 laser beam expandings fill
Put；4 aluminium fin heat sinks；Node photovoltaic cell more than 5；6 high transparency prisms；7 parabolic mirror surfaces；8 wireless charging platforms
Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Application scenarios are the unmanned plane of the line walking in power grid, and after not enough power supply, urgent need finds charging platform electric energy supplement.
Wireless charging platform is installed in high tower, unmanned plane Automatic-searching is suspended on charging platform, and energy acceptance device starts as nothing
Man-machine charging.
The technical scheme is that：Referring to Fig. 1, the present embodiment is using laser beam in normal atmospheric space propagation energy
Amount, by the use of form of energy such as electric energy, solar energy, wind energies as excitation energy source 1, encourages 808nm optical-fiber coupling semiconductor lasers
Device 2 is used as system source.After beam shaping, the thicker energy laser light of high light beam quality, small beam divergence angle, diameter is produced
Beam.The parallel injection of widened laser after laser beam expander 3, and the base of laser beam expander 3 move and have with
Track laser function, when laser is incident with various angles, can adjust the posture of laser beam expander 3 rapidly.Via parabolic mirror surface 7
Laser beam reflection is converged in high transparency prism 6, by photoelectric conversion material is polysilicon, monocrystalline silicon, iii-v partly lead
More node photovoltaic cells 5 such as body convert light energy into electric energy, can directly be minute vehicle after over commutation, filtering
