Description

technical field [0001] The invention relates to the technical field of underwater wireless charging, in particular to an unmanned submersible, an underwater wireless charging device and a charging method. Background technique [0002] Submersibles can replace divers in salvage of sunken ships, deep water exploration, and underwater cable laying. Hydrographic and oceanographic units use UUVs equipped with a large number of sensors to map the seabed and provide data necessary for submarine and amphibious warfare planning; unmanned underwater vehicles are also used for search and rescue, intelligence, surveillance and reconnaissance missions; meanwhile, the United States has begun testing a The new deep-sea UUV is used to track enemy submarines, and it has become a practical possibility to develop strike capabilities with strict timing requirements. It can be used as a bait to lure enemy submarines away from the ship formation, and to encircle and annihilate under the coordina...

AI Technical Summary

Problems solved by technology

[0005] ① The docking operation is complicated, which is likely to cause safety hazards during the docking operation;

[0006] ② The overall installation of the wet plug system is expensive, which is not conducive to promotion;

[0007] ③The post-maintenance of wet plugging technology is complicated and difficult, and it is easy to cause hidden dangers of electric leakage;

[0008] Second, the underwater wireless charging technology solves the potential safety hazard of plugging and unplugging the connector during underwater wireless charging, but the underwater wireless charging is different from the ground wireless charging technology. The underwater wireless charging technology has more difficulties, including : The underwater coil alignment is a three-dimensional space alignment, which is different from the two-dimensional alignment of road car wireless charging, and long-distance guidance cannot use GPS, Bluetooth, infrared and other alignment methods, and the above signals are not suitable for water media. The penetrating effect makes underwater guidance and precise alignment a major problem in underwater wireless charging;

[0011] ②The second positioning unit of this patent adopts underwater acoustic positioning or optical positioning, which does not take into account that the error of underwater acoustic positioning is large, and in optical positioning, the underwater is black, and it is not visible like the visible light on the road. In the state of alignment, the precise positioning described by it cannot be realized at all; (even if the strong light is turned on, this also violates the requirement of concealment and confidentiality for underwater charging)

[0012] ③ After the patent has completed its alignment, it is convenient to use wireless charging technology such as magnetic coupling to start charging. The water flow is moving. How to ensure that the charging device is fixed? It is necessary to repeatedly open the propulsion module for continuous action. This positioning method is too complicated and difficult to achieve accurate positioning;

[0013] In the prior art, in order to ensure the realization of wireless charging, there is another invention patent, the application number is: 201610179703.4, and the name of the invention is "a wireless charging device for autonomous underwater vehicles". The patent introduces various The connection relationship of wireless charging, how to realize the wireless charging principle of the transmitting coil and the receiving coil, but for the real realization of underwater wireless charging, there are many insufficient disclosures and unreasonable designs in this patent, such as:

[0014] ① The autonomous underwater vehicle and the underwater charging device are connected through the capture robot arm; the capture mechanism is used to capture the capture robot arm; this patent briefly summarizes the complex alignment of three-dimensional underwater, combined with the manual In the accompanying drawings, no further specific technical descriptions for realizing underwater three-dimensional alignment can be found, especially figure 2 , is an example of the existing wireless charging technology; the whole article cannot realize the alignment of wireless charging underwater;

[0016] ③The underwater docking is completed through the capture robot arm of the aircraft and the capture mechanism of the underwater charging device, and the final positioning is achieved by the locking mechanism. How to complete the precise positioning of the transmitting coil and the receiving coil? The inventor did not consider that underwater alignment is more complicated, it is three-dimensional alignment, and GPS cannot be used for long-distance guidance, and the premise that the existing positioning methods available on land are basically useless
