Description

Technical Field

[0001] The utility model belongs to the technical field of underwater equipment, and particularly relates to a magnetic coupling optimization structure of an underwater equipment. Background Art

[0002] There are various types of underwater monitoring and operation equipment. The operation of the equipment requires continuous power supply, and the data collected by the equipment and its own operation data also need to be uploaded. If the traditional wired method is used to realize the power supply and communication transmission of the equipment, long-distance cables need to be laid, which is not only costly, but also very complex in installation and maintenance. At the same time, the presence of the cables will limit the moving range of the underwater equipment and affect the operation flexibility. Especially in deep-sea operations, the cables are easily affected by ocean currents, marine organisms and underwater topography, resulting in fracture or damage. In addition, the wired connection also increases the physical connection points between the equipment, and these connection points are easily corroded and worn, thus affecting the reliability and service life of the system.

[0003] In order to overcome these disadvantages, underwater wireless communication and wireless charging systems have emerged. A movable power supply is placed on one side of the underwater equipment, and electric energy and data are transmitted through wireless charging and wireless communication methods to supply power to the underwater equipment and download the data in the underwater equipment. By replacing the power supply, the power supply to the underwater equipment is maintained, and the data is carried to the water surface.

[0004] The underwater wireless communication and wireless charging system mainly includes a transmitting end and a receiving end. The transmitting end is equipped with a transmitting coil, and the receiving end is equipped with a receiving coil. During operation, the transmitting coil generates an electromagnetic field, and after the receiving coil senses the electromagnetic field, it performs energy reception and signal processing, so as to realize wireless communication and charging. In addition, during operation, the transmitting coil and the receiving coil need to be aligned. In practical applications, considering the operability, a certain distance is usually set between the transmitting end and the receiving end. This usage method has the following problems:

[0005] 1. The conductivity of seawater is very high. The seawater between the antenna end faces of the transmitting end and the receiving end, as well as the seawater around the antenna, will cause significant attenuation to the propagation of electromagnetic signals, thereby reducing the electric energy transmission rate and data transmission efficiency;

[0006] 2. In actual operation, it is often difficult to accurately control the distance between the transmitting end and the receiving end. Inaccurate distance control will cause the coupling parameters between the transmitting coil and the receiving coil to change, and the fluctuation of the coupling parameters will cause the system to work unstably, thereby affecting the transmission efficiency or increasing the energy loss;

[0007] 3. In an underwater environment, sea organisms such as seaweeds and shellfish are likely to adhere to the surfaces of the antennas at the transmitting end and the receiving end. These attachments will interfere with the alignment and spacing control of the coils, further affecting the transmission effect and charging efficiency of the system. The attachment of sea organisms also increases the difficulty of maintenance and may cause physical damage to the equipment. Summary of the Utility Model

[0008] In view of the deficiencies in the related art, the present utility model provides an optimized magnetic coupling structure for underwater equipment to solve the problems of signal attenuation, difficult spacing control, and easy attachment of sea organisms existing in the current wireless communication and charging systems for underwater equipment.

[0009] The present utility model provides an optimized magnetic coupling structure for underwater equipment, which includes two underwater equipment. Antennas are installed in the shells of the two underwater equipment, and both antennas are located at the first end of the corresponding shell. The two shells are connected by a connecting mechanism, and the first ends of the two shells are arranged opposite to each other to align the two antennas.

[0010] First inner standard points and second inner standard points are set on both antennas, and first outer standard points and second outer standard points are set on both shells.

[0011] The first inner standard point is located on the edge of one side of the corresponding antenna and is longitudinally aligned with the corresponding first outer standard point; the second inner standard point is located on the surface of the side of the corresponding antenna away from the first end of the shell and is transversely aligned with the corresponding second outer standard point.

[0012] The two underwater equipment are respectively a first underwater equipment and a second underwater equipment. There is a gap between the first inner standard point and the corresponding first outer standard point of the first underwater equipment, so that the magnetic flux density of the first outer standard point of the first underwater equipment is α 1 times that of the magnetic flux density of the corresponding first inner standard point; there is a gap between the second inner standard point and the corresponding second outer standard point of the first underwater equipment, so that the magnetic flux density of the second outer standard point of the first underwater equipment is β 1 times that of the magnetic flux density of the second inner standard point; there is a gap between the first inner standard point and the corresponding first outer standard point of the second underwater equipment, so that the magnetic flux density of the first outer standard point of the second underwater equipment is α 2 times that of the magnetic flux density of the corresponding first inner standard point; there is a gap between the second inner standard point and the corresponding second outer standard point of the second underwater equipment, so that the magnetic flux density of the second outer standard point of the second underwater equipment is β 2 times that of the magnetic flux density of the second inner standard point; α 1 and α 2 and β 1 and β 2 are all greater than 0 and less than 1.

[0013] A partition is clamped and installed between two underwater devices. The partition is a non-metallic component, and its two side surfaces are both attached to the end faces of the corresponding first ends of the shells.

[0014] In some embodiments, one underwater device is a measuring device and the other underwater device is a power supply device;

[0015] A measuring end controller is installed in the shell of the measuring device. The measuring end controller is electrically connected to the corresponding antenna and is connected with a sensor through a wire;

[0016] A power supply end controller and a power supply battery are installed in the shell of the power supply device. The power supply end controller is electrically connected to the power supply battery and the corresponding antenna.

[0017] In some embodiments, a memory is installed in the shell of the power supply device, and the power supply end controller is electrically connected to the memory.

[0018] In some embodiments, the partition is an elastic member, so as to cause it to generate elastic deformation under the clamping of the two underwater devices.

[0019] In some embodiments, the surfaces of the partition cover the end faces of the corresponding first ends of the shells.

[0020] In some embodiments, the antenna is a loop antenna, and the shell is correspondingly arranged in a cylindrical shape.

[0021] In some embodiments, the connecting mechanism includes a first connecting seat and a second connecting seat. The first connecting seat and the second connecting seat are respectively fixedly installed on the two shells. A connecting stud is fixedly installed on the end face of the first connecting seat. After the connecting stud passes through the assembly hole opened in the second connecting seat, a connecting nut is threadedly installed, and the connecting nut is attached to the end face of the second connecting seat away from the first connecting seat.

[0023] In some embodiments, the connecting nut is provided with a handle.

[0024] In some embodiments, there is a gap between the first connecting seat and the second connecting seat.

[0025] Based on the above technical solution, in the embodiment of the present utility model, by setting the magnetic flux density of the internal and external standard points, a gap is formed between the antenna and the outer wall of the housing in the transverse and longitudinal directions. Furthermore, most of the electromagnetic field generated by the antenna at the transmitting end is in the housings of the two underwater devices, reducing the part of the electromagnetic field entering the surrounding seawater, thereby reducing the influence of seawater on the attenuation of electromagnetic signals and ensuring the power transmission efficiency and data transmission efficiency. The space between the two underwater devices is filled with a non-metallic partition, which not only prevents the attachment of marine organisms between the two underwater devices, but also enables the distance between the two underwater devices to be fixed through the partition, maintaining the alignment and distance between the antennas, avoiding changes in the coupling parameters between the transmitting-end antenna and the receiving-end antenna, and avoiding instability of the system operation caused by fluctuations in the coupling parameters, thereby avoiding affecting the transmission efficiency or increasing energy loss, and solving the problems of signal attenuation, difficult distance control, and easy attachment of marine organisms existing in the current underwater device wireless communication and charging system.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0037] As Figures 1 to 2 shown, in a schematic embodiment of the magnetic coupling optimization structure of the underwater device of the present utility model, the magnetic coupling optimization structure of the underwater device includes two underwater devices 1.

[0038] Antennas 12 are installed in the housings 11 of the two underwater devices 1. Both of the two antennas 12 are located at the first end of the corresponding housing 11. The two housings 11 are connected by a connecting mechanism 2. The first ends of the two housings 11 are arranged opposite to each other so that the two antennas 12 are aligned. The two underwater devices 1 perform wireless charging and wireless communication through the two mutually aligned antennas 12.

[0039] On each antenna 12, a first inner standard point 13 and a second inner standard point 14 are provided, and on each housing 1, a first outer standard point 15 and a second outer standard point 16 are provided. The first inner standard point 13 is located on the edge of the corresponding side of the antenna 12 and is longitudinally aligned with the corresponding first outer standard point 15. The second inner standard point 14 is located on the surface of the corresponding side of the antenna 12 away from the first end of the housing 11 and is transversely aligned with the corresponding second outer standard point 16.

[0040] The two underwater devices 1 are a first underwater device and a second underwater device respectively. There is a gap between the first inner standard point 13 and the corresponding first outer standard point 15 of the first underwater device, so that the magnetic flux density of the first outer standard point 15 of the first underwater device is α 1 times that of the magnetic flux density of the corresponding first inner standard point 13; there is a gap between the second inner standard point 14 and the corresponding second outer standard point 16 of the first underwater device, so that the magnetic flux density of the second outer standard point 16 of the first underwater device is β 1 times that of the magnetic flux density of the second inner standard point 14; there is a gap between the first inner standard point 13 and the corresponding first outer standard point 15 of the second underwater device, so that the magnetic flux density of the first outer standard point 15 of the second underwater device is α 2 times that of the magnetic flux density of the corresponding first inner standard point 13; there is a gap between the second inner standard point 14 and the corresponding second outer standard point 16 of the second underwater device, so that the magnetic flux density of the second outer standard point 16 of the second underwater device 14 is β 2 times that of the magnetic flux density of the second inner standard point; α 1 、α 2 、β 1 and β 2 are all greater than 0 and less than 1.

[0041] A partition 3 is clamped and installed between the two underwater devices 1. The partition 3 is a non-metallic component, and both of its side surfaces are attached to the end faces of the corresponding first end of the housing 11.

[0042] α 1 、α 2 、β 1 and β 2They are all attenuation ratio coefficients, and are all set manually. By making the ratio of the outer and inner magnetic flux densities reach the attenuation ratio coefficient in the horizontal and vertical directions, the distances between the outer wall of the housing 11 and the antenna 12 in the horizontal and vertical directions are set, so that the antenna 12 is at the center of the first end of the housing 11, increasing the external dimensions of the housing 11. The housing 11 is a cavity structure and is made of a non-metallic material. When any one of the two underwater devices 1 is used as the transmitting end, most of the electromagnetic field generated by its antenna 12 is in the space where the housing 11 is located, avoiding more electromagnetic fields entering the surrounding seawater and causing magnetic field attenuation. Thus, when the other is used as the receiving end, its antenna 12 can receive an electromagnetic field with sufficient intensity, so as to obtain electrical energy through wireless charging to the greatest extent, or more accurately, obtain data through wireless communication. Among them, α 1 、α 2 、β 1 and β 2 are generally set between 0.2 and 0.7.

[0043] The first inner standard point 13 is set on the longitudinal edge of the antenna 12, and multiple ones can be set. Each first inner standard point 13 is correspondingly provided with a first outer standard point 15. The second inner standard point 14 is set at any position on the surface of the antenna 12, and multiple ones can be set. Each second inner standard point 14 is correspondingly provided with a second outer standard point 16. When multiple groups of inner and outer standard points are set, the ratio of the outer and inner magnetic flux densities of all the inner and outer standard points needs to reach the attenuation ratio coefficient.

[0044] Both surfaces of the partition 3 are attached to the end faces corresponding to the first ends of the housings 11, so that no sea creatures will adhere to the end faces of the first ends of the housings 11, and the distance between the end faces of the first ends of the two housings 11 is the thickness of the partition 3, so that the distance between the two underwater devices 1 is fixed and will not change due to the adhesion of sea creatures.

[0045] In the above-described exemplary embodiment, the magnetically coupled optimized structure of the underwater device forms a gap between the antenna 12 and the outer wall of the housing 11 in the transverse and longitudinal directions through the magnetic flux density settings of the internal and external standard points. As a result, most of the electromagnetic field generated by the antenna 12 at the transmitting end is within the housings 11 of the two underwater devices 1, reducing the portion of the electromagnetic field that enters the surrounding seawater, thereby reducing the impact of seawater on the attenuation of electromagnetic signals and ensuring the power transmission rate and data transmission efficiency. The space between the two underwater devices 1 is filled with a non-metallic partition 3, which not only prevents the attachment of marine organisms between the two underwater devices 1 but also enables the distance between the two underwater devices 1 to be fixed through the partition 3, maintaining the alignment and distance between the antennas 12, preventing changes in the coupling parameters between the transmitting-end antenna 12 and the receiving-end antenna 12, avoiding instability of the system operation due to fluctuations in the coupling parameters, and thus avoiding affecting the transmission efficiency or increasing energy loss, solving the problems of signal attenuation, difficult distance control, and easy attachment of marine organisms existing in the current wireless communication and charging system of the underwater device 1.

[0046] In some embodiments, when two underwater devices form an underwater measurement system, one underwater device 1 is a measurement device 1A, and the other underwater device 1 is a power supply device 1B.

[0047] A measurement-end controller 17 is installed inside the housing 11 of the measurement device 1A. The measurement-end controller 17 is electrically connected to the corresponding antenna 12 and is connected to a sensor (not shown in the drawings) through a wire. A power-supply-end controller 18 and a power supply battery 19 are installed inside the housing 11 of the power supply device 1B. The power-supply-end controller 18 is electrically connected to the power supply battery 19 and the corresponding antenna 12.

[0048] The power-supply-end controller 18 of the power supply device 1B transmits the electrical energy in the power supply battery 19 to its antenna 12, and the electrical energy is transmitted through the induced electric field generated by electromagnetic coupling between the two antennas 12, thereby transmitting the electrical energy to the measurement device 1A, enabling the power supply device 1B to supply power to the measurement device 1A through wireless charging.

[0049] The measurement device 1A is fixed underwater. To meet the measurement requirements, the sensor connected to the measurement device 1A needs to be fixed underwater as required. The connecting mechanism 2 is detachable, enabling the connection between the power supply device 1B and the measurement device 1A to be disconnected. Thus, when the power supply battery 19 in the power supply device 1B runs out of power, an ROV can carry a fully charged power supply device, replace the old power supply device, and carry it to the water surface, thereby maintaining continuous power supply to the measurement device 1A underwater.

[0050] In some embodiments, a memory 10 is installed in the housing 11 of the power supply device 1B, and the power supply terminal controller 18 is electrically connected to the memory 10. Through the magnetic coupling between the two antennas 12, the measuring device 1A transmits the measured data to the memory 10 of the power supply device 1B by wireless communication. Thus, when the power supply device 1B is replaced, the measured data is carried to the water surface by the ROV with the old power supply device, so that the remote terminal device can download and analyze the measured data.

[0051] In some embodiments, the partition 3 is an elastic member, such as a rubber plate, a resin plate, or other non-metallic materials with elasticity and non-conductivity. Under the clamping of the two underwater devices 1, the partition 3 undergoes elastic deformation to a certain extent. Through the elastic force, both surfaces of the partition 3 are closely attached to the corresponding first end faces on one side, minimizing the gap between the partition 3 and the first section end face, thereby preventing seawater from entering and causing electromagnetic field attenuation.

[0052] In some embodiments, the surface of the partition 3 covers the end face of the first end of the corresponding housing 11. Both surfaces of the partition 3 are attached to the corresponding first end faces and completely cover them, leaving no part of the first end face exposed, and all are covered by the partition 3, minimizing the attachment of marine organisms on the first end face and ensuring the stability of the distance between the two underwater devices 1.

[0053] In some embodiments, the antenna 12 is a loop antenna, and the housing 11 is correspondingly arranged in a cylindrical shape (not shown in the drawings). The loop structure of the antenna 12 makes its first inner standard point 13 located on the circumference where the outer edge of the antenna 12 is located. The outer wall of the cylindrical housing 11 makes the first outer standard point 15 arranged in a circular shape accordingly. Thus, at various angular positions, the magnetic flux density ratio between the outer and inner standard points is maintained at the attenuation ratio coefficient longitudinally, ensuring that most of the electromagnetic field generated by the antenna 12 is inside the housing 11. The cylindrical shape occupies less volume than a rectangular body, making it easier to miniaturize the device.

[0054] In some embodiments, as Figure 3 shown, the connecting mechanism 2 includes a first connecting seat 21 and a second connecting seat 22. The first connecting seat 21 and the second connecting seat 22 are respectively fixedly installed on the two housings 11. A connecting stud 23 is fixedly installed on the end face of the first connecting seat 21. After the connecting stud 23 passes through the assembly hole opened in the second connecting seat 22, a connecting nut 24 is threadedly installed, and the connecting nut 24 is attached to the end face of the second connecting seat 22 away from the first connecting seat 21.

[0055] The connecting nut 24 is rotated to move axially along the connecting stud 23 and approach the first connecting seat 21, thereby pushing the second connecting seat 22 toward the first connecting seat 21. As the second connecting seat 22 approaches the first connecting seat 21, the underwater device 1 connected to the second connecting seat 22 approaches another underwater device 1, and the distance between the two underwater devices 1 is reduced. The partition plate 3 between the two is clamped and fixed by a pulling connection method.

[0056] When the partition 3 is an elastic member, the partition 3 is clamped and fixed, and the elastic force generated by it can push both underwater devices 1 outward, so that the surface of the second connecting seat 22 is in closer contact with the connecting nut 24, increasing the friction between the two, improving the stability of the connecting nut 24, and making the connecting mechanism 2 more stably connect the two underwater devices 1.

[0057] In some embodiments, two groups of connection mechanisms 2 are provided, which are respectively located on both sides of the two underwater devices 1. Both sides of the two underwater devices 1 are connected by the connection mechanism 2, so as to prevent the other side between the two underwater devices 1 from opening after the connection mechanism 2 on one side is pulled tight, and keep the partition 3 in close contact with the end faces of the two underwater devices 1. At the same time, the two connection mechanisms 2 also form a limiting structure, which prevents the partition 3 from escaping from the space between the two underwater devices 1 from two directions, and further ensures the stability of the partition 3.

[0058] In some embodiments, the connection nut 24 is provided with a handle 25, so as to facilitate the ROV to rotate the connection nut 24 through a manipulator, thereby ensuring that the connection operation can be performed remotely by the ROV.

[0059] In some embodiments, a gap is provided between the first connecting seat 21 and the second connecting seat 22, providing a moving space for the two to approach each other, so that when the partition 3 adopts an elastic member, the first connecting seat 21 and the second connecting seat 22 can be further approached, pressing the partition 3 to make it more closely attached to the end face of the shell 11.

[0060] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0061] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
