Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, it should be pointed out that reality as described below
It applies example to be intended to convenient for the understanding of the present invention, and does not play any restriction effect to it.
As shown in Figure 1, autonomous underwater vehicle (AUV) platform of the present invention berths, formula wireless charging device is received including electric energy
Module 3 and electric energy output module 4, two modules be mounted in respectively on AUV1 and submarine observation network node platform 6 on.Electric energy receives mould
Block 3 is electrically connected by receiving terminal watertight cable 2 with the battery of AUV1, and electric energy output module 4 is seen by transmitting terminal watertight cable 5 and seabed
DC power supply electrical connection on survey grid node platform 6.
The structure of electric energy receiving module 3 is as shown in Figure 2.The size of electric energy receiving module 3 is depending on the size of AUV, and one
As width be slightly less than the width of AUV, length is less than the length of AUV.Electric energy receiving module 3 includes magnetic energy transmit coil 31, non-gold
Belong to shell 32, the second magnetic masking layer 33, permanent magnet 36, electric energy receiving circuit 37, magnetic energy transmit coil 31, the second magnetic masking layer 33
It is placed in non-metal shell 32 with permanent magnet 36, and with 34 embedding of casting glue, plays the role of the resistance to high undersea hydrostatic pressures of waterproof.
Second magnetic masking layer 33 is made of ferrite, is arranged on the bottom of electric energy receiving module 3 (under magnetic energy transmit coil 31
Side), between magnetic energy transmit coil 31 and AUV, the magnetic field and AUV formation that can prevent coil interfere with each other, and improve simultaneously
Electric energy transmission performance.
Shown in (a) and (b) in the structure such as Fig. 3 of electric energy output module 4.Magnetic energy in electric energy sending module 4 sends line
Circle is made of several subcoils 41, and subcoil 41 can be made but be not limited to rectangular, and the size of subcoil 41 is fitted according to specific needs
Work as selection, can not only ensure electric energy high efficiency of transmission, but also can be excessive and excessively complicated to avoid subcoil.When subcoil 41 stacks,
It is overlapping just like shown in Fig. 4, it ensure that entire flat magnetic field is substantially uniform, the nothing without magnetic field will not occur in subcoil adjacent
Region is imitated, when AUV, which rests on two subcoils, overlaps place, still can efficiently accomplish charging.
Bottom ferrite layer is placed in the bottom of subcoil 41, to improve electric energy efficiency of transmission, and under partly shielding effect coil
The leakage field of side.Metal shielding shell 44 is set in outermost layer, to shielded coil lower section and lateral remaining leakage field, to reduce sea
The eddy-current loss of water, but the surface layer of coil is not covered with Metal shielding shell 44, to avoid electric energy transmission is influenced.
Magnetic energy for emission coil surface layer surface layer ferrite layer 43 covers, and the saturation magnetic field intensity of surface layer ferrite layer 43 is more than
The magnetic field intensity of magnetic energy for emission coil, and less than the magnetic field intensity of permanent magnet 36.
When not having the stop of electric energy receiving module 3 on subcoil 41, surface layer ferrite layer 43 is in magnetic undersaturated condition, tool
There is larger magnetic conductivity, the magnetic field that most electric energy output modules 4 generate can be shielded, prevent it from entering in seawater and generate whirlpool
Stream loss；And the region covered by electric energy receiving module 3, due to the effect of 36 permanent magnets, the work of surface layer ferrite layer 43
State can skip high permeability region, into magnetic saturation area.As shown in figure 5, ferrite has larger before zone of saturation is entered
Magnetic conductivity, have a preferable magnetic screening action, and after entering magnetic saturation area, magnetic conductivity is rapidly reduced to the level close to air,
Lose its magnetic screening action.Therefore, electric energy output module 4 generate magnetic field, only by permanent magnet 36 cover near region energy
It enters in electric energy receiving module 3, and other redundances have been limited in electric energy output module 4 itself without entering sea
In water, because without generating eddy-current loss.
Subcoil 41, surface layer ferrite layer 43 and bottom ferrite layer are potted in 44 Metal shielding shells by casting glue 46
In, the electric energy transmission circuit 47 placed with side is connected, and is connect finally by watertight connector with submarine observation network node platform, from
Direct current energy input is obtained on platform.
The circuit diagram of entire underwater wireless charging unit is as shown in fig. 6, the electric energy output module in left side and the electric energy on right side
What receiving module was completely separate, without electrical contact during use.
Electric energy is typically to be transmitted under water in the form of direct current, so using direct current input as the defeated of electric energy output module
Enter.Direct current input is converted into high-frequency alternating current by high-frequency inverter A2 and is transferred in magnetic energy for emission loop A 4, magnetic energy for emission line
Circle A4 is made of subcoil cell array, and all subcoils are to be connected in parallel, connect again on each subcoil one it is independent
Coil switch A5, coil switch A5 are controlled by switch controller A1.Current sensor A3 is used to detect the current value of direct current input,
The result of detection can be fed back to switch controller A1 simultaneously.
Electric energy is transferred to by magnetic energy for emission loop A 4 on magnetic energy receiving coil B1, and by rectifying pressurizer B2, high frequency is handed over
Galvanic electricity is converted to stable DC, then charged manager B3 is adjusted to suitable voltage and current value, finally to the electricity on AUV
It charges in pond.
Battery is not comprised on electric energy receiving module 3, and is installed in AUV.
When AUV is rested on submarine observation network node platform, table side and the electric energy output module 4 of electric energy receiving module 3
Table side it is mutually close, electric energy output module 4 is powered；Later, switching gate device A1 gates each sub-line coil unit and is connected successively
Coil switch A5, and pass through current sensor A3 detection gating after input current variation.In radio energy transmission system,
The size of input current is different under different loads situation, therefore, when the increasing for the input current that current sensor A3 is detected
When dosage is higher than given threshold, illustrate that the subcoil of the gating produces larger impact to AUV chargings, current sensor A3 is informed
The coil unit is kept gating by switching gate device A1 by coil switch A5；If the power supply that current sensor A3 is detected
When input current incrementss are less than given threshold, illustrate that the incrementss only come from coil own loss, and to AUV charging nothings
Larger impact then turns off the sub-line coil unit.
It is not needing to due to carrying out being accurately positioned the advantages of difficulty is larger, and cost is higher, this gating method under water
The accurate position detection carried out using additional Underwater Navigation equipment to AUV, while can also only open effective to AUV chargings
A part of platform coil, to reduce unnecessary energy loss.
It is unfixed since the size of the electric energy receiving module 3 on AUV is with the different and different of AUV, therefore selects
Logical sub-line coil unit still can some area do not had and covered by the magnetic energy receiving coil on electric energy receiving module 3.
The effect of ferrite layer 43 on electric energy output module 4 exactly shields the magnetic that this part is not covered by electric energy receiving module
It is logical, it prevents it from entering in seawater, generates eddy-current loss, and by the region that electric energy receiving module 3 covers due to permanent magnet 36
Effect can skip high permeability region by the working condition of the ferrite layer of permanent magnet covering, and into magnetic saturation area, ferrite exists
Into before zone of saturation, there is larger magnetic conductivity, there is preferable magnetic screening action, and after entering magnetic saturation area, magnetic conductivity is fast
Prompt drop loses its magnetic screening action down to the level close to air.Therefore, the magnetic field that electric energy output module 4 generates, only by forever
Region can be entered in electric energy receiving module 3 near the covering of magnet 36, and other redundances have been limited in electric energy output
Without entering in seawater in module 4 itself, because without generating eddy-current loss.
