Cease conveyer.
Background technology
The working equipment of the overwhelming majority is required for energy supply, and traditional energy transmission means passes through the slotting of contact mostly
Pull out interface and transmit energy to end product, this transmission means can bring friction, the problems such as being also easy to produce electric spark, so as to influence
The security reliability of electrical equipment, the need for traditional corded power transmission means can not meet some particular applications, such as
Mine and under water etc..
Under water in environment, electric energy and signal transmission interface device are often needed, existing frequently-used interface arrangement is wet under water
Connecting-disconnecting interface, wet connecting-disconnecting interface technology relative maturity, but there is inadequate natural endowment：Water around working environment has conduction
Property, any minimal amount of water leakage may all cause short circuit, even result in accident；Wet plug joint must be by being up to tens of public affairs
The contact engaging and separating force of jin could realize normal plug operation, be a very big challenge to the electromechanical equipment worked automatically；Wet plug
Interface needs abrasion caused by frequently extruding plug operation, huge contact engaging and separating force to cause service life seriously to reduce, and needs
Frequently safeguard and just can guarantee that safety；Wet connecting-disconnecting interface price general charged is high, for some simple equipment, wet connecting-disconnecting interface into
Originally be even more than equipment itself.
Wireless energy transmission technology can make us break away from traditional energy transmission means, by electromagnetic radiation, field coupling,
The forms such as magnetic coupling, ultrasonic wave realize contactless energy transmission, thus avoid because of the brought abrasion of plug operation and
The problems such as short circuit that sealing leak is brought, extension device underwater working time, raising operation flexibility and working range.
Common wireless energy and transmission signal vector are all the electromagnetic waves utilized, but water has very strong absorption to electromagnetic wave
Ability, the decay of electromagnetic wave is serious in water, can only be transmitted in extremely short distance, therefore utilizes sonic transmissions energy under water
There is unique advantage with signal, at the same sonic transmissions mode have big no electromagnetic pollution, environment-friendly, power, good directionality,
The features such as penetration capacity is strong, propagation distance is remote and is easily obtained the acoustic energy relatively concentrated, therefore can be realized under water using sound wave
Efficient energy and information transfer.
The propagation of sound wave has directionality, and general ultrasonic transducer generates sound field into sector, the sound that receiving terminal is received
Wave energy only accounts for a part for emitted energy.Sound wave can be improved by using the sound wave of rational method and apparatus focus emission
Utilization ratio, so as to improve the efficiency of transmission of wireless energy and signal.
The content of the invention
In view of the above-mentioned problems of the prior art, being passed the invention provides a kind of wireless energy based on sound wave and information
Send device.
The technical solution adopted for solving the technical problem of the present invention is：
The present invention includes transmitting terminal and receiving terminal；Transmitting terminal and receiving terminal are respectively provided with transducer, and the transducer is set
In respective intracavitary in midair；During work, two and half cavitys dock to form closed cavity, by transmitting terminal transducer by electric energy and electricity
Signal is converted to sound wave, and sound wave is in cavity directly or through being traveled to after one or many reflections at receiving terminal transducer；Connect
The sound wave received is converted to electric energy and electric signal by receiving end transducer；By this process, energy and signal are passed by sound wave
Pass mode and be delivered to receiving terminal from transmitting terminal.
Furtherly, the transducer of intracavitary is circumscribed with control circuit in midair.
Furtherly, transmitting terminal is docked with receiving terminal using concaveconvex structure.
The present invention docks the cavity to be formed to realize sound building-up effect by transmitting terminal and receiving terminal, and this effect can be improved and connect
The intensity of acoustic wave that receiving end transducer is received, so as to improve transmission efficiency.
