Problems solved by technology

However, due to the immaturity of the existing docking technology and positioning technology, the unmanned submersible can achieve a front-to-back position alignment of 0-30mm after entering the docking station, but it is difficult for the unmanned submersible to roll due to deep ocean currents. avoid
The roll of the unmanned submersible caused by ocean currents will cause the primary and secondary sides of the magnetic coupling mechanism to shift, which will affect the power and efficiency of power transmission. The most direct and effective way to solve this problem is to give priority to the lack of Performance degradation caused by the roll of the human submersible
[0003] Among the existing schemes, some research institutions have proposed a semi-embedded magnetic coupling mechanism in scientific literature, but this will undoubtedly change the hydrodynamic characteristics of the unmanned submersible, affecting its movement characteristics and maneuverability; some research institutions have designed 360 ° Surrounding fully embedded solenoid coil magnetic coupling mechanism to achieve rotational symmetry under 360° offset, but this magnetic coupling mechanism is very large in volume and weight, which is not conducive to the lightweight design of unmanned submersibles

Embodiment 1

[0044] like Figure 8 As shown, the main magnetic circuit coupling is the mutual inductance M1 of the planar arc-shaped solenoid multi-coil structure 1#~5# at the transmitting end and the planar arc-shaped solenoid coil at the receiving end and the planar arc-shaped solenoid multi-coil structure at the transmitting end. The mutual inductance M2 between the coil structure 1#~5# and the planar arc-shaped DD coil at the receiving end, the transmitting end side also includes a high-frequency inverter source and the first resonance compensation capacitor, and the receiving end side also includes a second resonance compensation capacitor, rectifier Filter circuit and unmanned underwater vehicle battery pack. Among them, such as Figure 8 The resonant compensation network shown is S-S structure, but those skilled in the art can choose other structural forms of compensation network according to the actual situation, such as S-P, P-P, P-S, LCC-S, LCC-LCC, S-LCC, LCL-S, LCL-LCL and ot...

[0046] like Figure 9 As shown, the 3kW wireless power transmission system of a 324mm caliber unmanned submersible is used as an example for illustration. Figure 9 The gaps shown are for coil winding distribution. The transmitting end is composed of five planar arc-shaped solenoid coils, and each coil is wound with 10 turns of Litz wire. The gap distance between the transmitting end and the receiving end is 50mm, which is the distance of wireless power transmission. The receiving end is composed of a planar arc-shaped DD coil and a planar arc-shaped solenoid coil. The outer dimension of the DD coil is 180mm*200mm, and it is wound with 10 turns of Litz wire. Wound at the center of the DD coil, 10 turns in total. The coil is wound by Litz wire. The frequency of the excitation current used can be 20kHz~200kHz. Higher frequency can get stronger transmission capacity. 200kHz uses single-strand Litz wire with a diameter of 0.05mm. The number of litz wires can be 0.1mm. .
