Cylindrical quadrupole plate structure underwater radio energy transmission device based on electric field coupling

Abstract

The invention belongs to the technical field of radio energy transmission, and relates to a cylindrical quadrupole plate structure underwater radio energy transmission device based on electric field coupling. The device comprises a transmitting part and a receiving part. The transmitting part is installed in the charging base station, and comprises a power supply, a high-frequency inverter module,a resonance compensation module and an electric energy transmitting terminal. The receiving part is installed in the underwater detector, and comprises an electric power receiving end, a rectifying module and a battery of the underwater detector. Two sets of electric energy transmitting and receiving terminals form a cylindrical quadrupole plate electric field coupling mechanism, which realizes the underwater radio energy transmission of cylindrical quadrupole plate structure based on electric field coupling. The invention directly supplies power to the detection equipment under water, whichcan shorten the charging time, improve the working efficiency and avoid unsafe factors such as electric leakage. In the underwater, especially in the seawater, the advantages are obvious, with no eddycurrent and low energy loss. The coupling electric field is basically confined between the capacitor plates, and the electromagnetic radiation is greatly reduced, which reduces the electromagnetic interference to the system.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and relates to an underwater wireless power transmission device with a cylindrical quadrupole plate structure based on electric field coupling. Background technique [0002] Nowadays, the application of underwater detection equipment is becoming more and more extensive. From the original cable connection power supply, it gradually develops into self-contained power supply. However, both of these methods require the detection device to return to the water surface to recharge after being used for a period of time. This process will undoubtedly waste a lot of time, and too frequent plugging and unplugging of the electrical connector will also cause loss to the connector. [0003] If the wireless energy transmission technology is used to directly supply power to the detection equipment underwater, the charging time can be shortened, the work efficiency can be improved, and unsafe ...

Problems solved by technology

For the traditional magnetic field coupling method, in the underwater environment, because the water medium is not pure and has a certain conductivity, it will cause eddy current loss; in addition, the magnetic field cannot pass through metal barriers, and it will cause electromagnetic interference to the equipment, resulting in a significant increase in transmission efficiency. reduce
