1. Wireless power transmission function implementation
The seabed non-contact type power transmission and communication hybrid wet plugging connector realizes non-contact type power transmission through an electromagnetic coupling principle, generally, seabed observation networks are supplied with direct current, when the seabed observation networks are used, socket ends are connected with power supply equipment, plug ends are connected with power utilization equipment, electric energy is supplied to internal circuits of the socket ends through socket watertight connectors 106, after plug connectors start to work, a first control processing module 111 can generate control signals, but the control signals are weak in voltage and not enough to directly drive switch tubes, therefore, after being amplified by a driving module 113, the control signals act on the switch tubes of an inversion module 114, and the direct current is inverted into alternating current with certain frequency through controlling the switch tubes according to a certain rule. After the inverted alternating current is subjected to resonance compensation through the first compensation module 115, a magnetic field is emitted through the primary side 101 of the electromagnetic coupler, then the secondary side 201 of the electromagnetic coupler in the magnetic field generates induced voltage in a coil, electric energy is transmitted to the plug end of the plug connector, and after the resonance compensation of the second compensation module 213, the alternating current electric energy is rectified into direct current by the rectification module 212 and transmitted to the electric equipment through the plug watertight connector 206.
In the design and selection of the actual circuit, the control processing module generally selects a microcontroller meeting the function and designs a corresponding peripheral circuit, the driving module has various realization methods to design the circuit, and the circuit can realize isolation and amplify the control signal when needed, so that the microcontroller can normally control the inversion process of direct current.
The inversion module and the rectification module can select one side of a voltage-voltage type full-bridge direct current conversion topology and mainly comprise four switching tubes, and the switching tubes can select MOSFETs or IGBTs. The rectifier module can select a full-bridge rectifier circuit for use, uncontrollable rectification is carried out, and self loss of the device can be reduced.
The compensation module is a resonance compensation circuit consisting of a digital programmable capacitor and a resistor, and can be adjusted according to requirements to obtain higher power factor and improve transmission efficiency.
The electromagnetic coupler is used as a key component of non-contact power transmission, and the quality of the electromagnetic coupler directly influences the quality of power transmission. The electromagnetic coupler is a coil winding which is wound by litz wires in a certain turn ratio and used in pairs, and the transmission voltage ratio can be changed by changing the turn ratio of the coil; the structural schematic diagram of the electromagnetic coupler is shown in fig. 7, by adopting the design of the cylindrical structure with the bottom, compared with a general sleeve coupling structure, the coupling area is increased, the coupling coefficient can be effectively improved, so that the power transmission efficiency is improved, after the winding of the coil is completed, the coil is encapsulated and shaped by using an epoxy resin material, then the primary side 101 of the electromagnetic coupler is fixed in the groove of the socket cavity 107, the secondary side 201 of the electromagnetic coupler is fixed at the convex outer side of the plug cavity, and when the plug connector is connected, only small gaps are reserved at two sides, so that the high power transmission quality is ensured.
2. Visible light communication module
The submarine non-contact energy transmission communication hybrid wet plugging connector has the main function of adopting visible light communication, has the advantages of large bandwidth, strong anti-interference capability and the like, and is suitable for being applied to the use environment of the connector. The optical communication module of the plug connector is composed of two parts: the first optical communication module 104 and the second optical communication module 204 have substantially the same structure, and two pairs of optical transmitters and receivers are used in cooperation to complete visible light signal transceiving, and then the optical modem is used to realize conversion between an electrical signal and a visible light signal. The disadvantage of using visible light communication is that a transparent optical transmission path is required between the transmitter and the receiver, and the alignment requirement is high, and fig. 5 and 6 show the optical paths of the plug-in visible light communication module in different situations: the shaded triangle is a common plane mirror and can reflect light; the strip structure with the shadow is a spectroscope, and can reflect light with a certain wavelength and transmit the light with the certain wavelength. The light path window is two equidimension circles that are located the axle center, no matter what kind of angle of plug connector connects like this, two light path windows can both accurately be adjusted well, and also can freely rotate around the axle after connecting, can not influence visible light signal's transmission, and such light path design makes alignment and directionality need not be considered when wet inserting and pulling out the connector and connect, reduces the connection degree of difficulty.
When the connector is in communication, the first optical transmitter 117 may transmit a visible light signal with a certain wavelength, and after two reflections of the plane mirror and the beam splitter in the first optical communication module 104, the visible light signal is received by the second optical receiver 216 through the beam splitter in the second optical communication module 204; the second optical receiver can emit a visible light signal of another wavelength, and after two reflections by the plane mirror and the beam splitter in the second optical communication module 204, the visible light signal is received by the first optical receiver 118 through the beam splitter in the first optical communication module 104. As can be seen from fig. 6, after rotating a certain angle, a similar light path is still established, and the visible light communication can still be performed normally. The main body of the optical communication module, except for the plane mirror and the spectroscope, is made of transparent pressure-resistant material, and the optical communication module is respectively fixed on the inner sides of the cavity according to the corresponding positions of the optical path windows of the socket cavity 107 and the plug cavity 207 and is sealed.
3. Quick buckle connection structure
The underwater robot or AUV has limited mobility, and if a complex connection mode or a large acting force is needed, the connection of the wet plug connector is difficult, so that the seabed non-contact energy transmission and communication hybrid wet plug connector is designed into a quick connection structure. The basic principle of the structure is that the socket and the plug are fixed together by utilizing the buckle structure, and the socket and the plug can naturally fall off by loosening the buckle when the disconnection is needed.
The realization of the snap quick connection structure is completed by the cooperation of the fixed clamping groove 103, the fixed clamping fin 203, the elastic sleeve 208 and the sliding sleeve 209. In a normal state, the elastic sleeve 208 is in a slightly compressed state, the sliding sleeve 209 is abutted along the axial direction, the fixed clamping fin 203 made of elastic material is slightly bent downwards under the pressure of the sliding sleeve, the lowest edge of the fixed clamping fin is flush with the bottom of the fixed clamping groove 103, when the socket and the plug are connected with each other, the fixed clamping fin 203 can be clamped into the fixed clamping groove 103 only by slight force, and the fixed clamping fin cannot be pulled out by reverse pull force; when disconnection is required, the sliding sleeve 209 is slid downward, the elastic sleeve 208 is further compressed, the fixing snap fin 203 is released, the socket end is thereby released, and the snap structure is restored to the original state again by the elastic sleeve 208 when the external force acting on the sliding sleeve 209 is removed.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
