Description
Technical Field
The utility model belongs to the field of underwater wireless charging, and particularly relates to an underwater wireless charging energy pickup.
Background
Electrically driven underwater equipment (such as an underwater robot or an underwater vehicle) requires electrical power to achieve permanent operation under water. The underwater wireless charging technology is one of the ways to supply electric energy to underwater equipment.
For example, as shown in "an autonomous underwater vehicle is under water wireless charging device" disclosed in CN105703458a, currently existing energy pickup modes of under water wireless charging are generally flat (using a flat coil module), i.e. a coupling mechanism of a transmitting end and a receiving end is installed in a flat plate, and energy is transmitted from the transmitting end to the receiving end by means of magnetic coupling. Since the area of the coupling mechanism between the transmitting end and the receiving end is increased continuously under the same transmission distance in order to transmit larger power, the area and the matched structure occupy larger space.
In addition, the prior art is also beneficial to the installation and maintenance of the coupling mechanism by dividing the coupling mechanism into blocks. However, mutual coupling exists between adjacent transmitting coils and adjacent receiving coils (shown in fig. 1) in the common block design, namely, lp1, lp2, ls1 and Ls2 are all coupled, so that workload and difficulty are increased in product model analysis and parameter design work (shown in fig. 2), and the design of a better underwater wireless charging system is not facilitated.
Based on this, the applicant considered to design an underwater wireless charging energy pick-up that could help to improve the efficiency, accuracy of the system performance analysis and to help to improve the feasibility of the wireless charging system (design).
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to solve the technical problems that: how to provide an underwater wireless charging energy pick-up that can help to improve the efficiency, accuracy of system performance analysis and to help to improve the feasibility of wireless charging systems (designs).
In order to solve the technical problems, the utility model adopts the following technical scheme:
an underwater wireless charging energy pickup comprises a transmitting coil and a receiving coil which are connected through magnetic coupling; the method is characterized in that:
The transmitting coils are arranged on at least two continuous surfaces in the same circumferential direction of the rectangular body-shaped structure; the receiving coils are arranged in one-to-one correspondence;
The receiving coils jointly clamp and wrap the transmitting coils in the same circumferential direction of the rectangular body-shaped structure to realize coupling connection.
Compared with the prior art, the underwater wireless charging energy pickup has the advantages that:
Each surface of the rectangular body type structure can keep the verticality between two adjacent surfaces, so that the magnetic field directions excited by every two adjacent transmitting coils are generally intersected, and therefore the two adjacent transmitting coils are mutually decoupled; when the receiving coil is over against the transmitting coil within the magnetic coupling distance, the receiving coil generates alternating current and excites the magnetic field excited by the transmitting coil after sensing the magnetic field;
Similarly, the magnetic fields excited by adjacent receiving coils are generally intersected and thus decoupled from each other (i.e., M1-2-, M1+2+ in FIG. 2 are negligible, and M12 and M21 are negligible, with the four sets of coils coupled only by M11, M22, M33 and M44).
By the above, this technical scheme can realize:
After decoupling of every two adjacent transmitting coils (receiving coils), the analysis complexity and difficulty of the underwater wireless charging model are simplified, and the design calculation amount can be reduced, so that the efficiency and accuracy of system performance analysis can be improved, and the feasibility of the wireless charging system (design) can be improved.

Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.

The receiving coils jointly clamp and wrap the transmitting coils in the same circumferential direction of the rectangular body-shaped structure to realize coupling connection.
The transmitting coils are connected in series or in parallel; the receiving coils are connected in parallel.
During operation when all receiving coils clamp the wrapped transmitting coil: it is difficult to ensure that the transmitting coil and the receiving coil are opposite to each other one by one, and the situation that the transmitting coil and the receiving coil are misplaced easily exists; the technical scheme is as follows: the parallel connection mode is adopted between the receiving coils, so that the threshold quantity of each receiving coil can be increased (thereby helping to increase the receiving power), and the functions of normal operation of the system can be satisfied when the transmitting coil and the receiving coil are misplaced (as shown in fig. 3, for example, when Lp1 is used for Ls2, lp2 is used for Ls3, lp3 is used for Ls4 and Lp4 is used for Ls1, the system can also be used normally), so that the system has better flexibility.
Each of the transmitting coil and the receiving coil is a flat coil module.
The flat coil module has the advantages of larger coupling area and heat dissipation area and more reliable use.
The transmitting coils are provided on four to six surfaces of the rectangular body-type structure.
In this way, compared with a single transmitting coil and a receiving coil, the scheme can fully utilize four to six surfaces of the rectangular body type structure to set the transmitting coil, and can transmit four times or even six times of power.
A first embodiment (four consecutive surfaces of a rectangular body-type structure are provided with said transmitting coils) is shown in fig. 4 and 5:
Each receiving coil is fixedly arranged on a mounting substrate made of nonferromagnetic hard materials; the two adjacent mounting substrates are fixedly connected by adopting a fixed connecting piece, and all the mounting substrates are enclosed together to form a collar-type structure;
The middle hollow part of the lantern ring type structure is used for laterally inserting the rectangular body type structure where the transmitting coil is located.
The receiving coils are fixedly connected by adopting the fixed connecting pieces and jointly enclose to form a collar-type structure, so that the receiving coil has the advantages of simple structure and easiness in processing and production; and the structure is in use: when the underwater equipment needs to be charged, the underwater equipment stretches out of the collar-type structure after sailing into the charging dock to complete positioning; the rectangular structure with the rear transmitting coil can be laterally inserted into the collar-type structure for wireless charging; the operation is also simple.

The mounting substrates can be unfolded to be flat or folded to be in a clamping jaw type structure, the folding of the mounting substrates can be completed manually by operators, and the folding of the mounting substrates to be in the clamping jaw type structure can be maintained by a limiting and maintaining structure.
A fifth embodiment is shown in fig. 10:

According to the technical scheme, each intermediate connecting piece can be heated through electrifying or the water temperature of each intermediate connecting piece is heated, so that the intermediate connecting piece can be deformed after reaching the phase transition temperature, and the receiving coil sleeve is clamped on the transmitting coil, so that wireless charging can be performed.
