Description

Technical Field

[0001] This application relates to the field of marine equipment, and in particular to an underwater active lifting device and equipment based on magnetic fluid. Background Technology

[0002] Ocean exploration is the foundation and crucial support for the development of marine science. Deep-sea submersible buoys play a vital role in this field, enabling continuous, all-weather exploration of the same sea area. Traditional BeiDou buoys float on the surface, offering poor concealment and making them easily spotted and retrieved by passing vessels, causing incalculable losses to scientific research experiments and even leading to experiment failure. While BeiDou buoys are well-concealed underwater, the underwater environment prevents them from transmitting or receiving BeiDou signals, thus hindering their intended functions.

[0003] The most common unattended underwater lifting devices currently available often use motors to drive changes in the volume of the oil bladder to achieve underwater lifting and lowering. For example, CN 104386208 B discloses an underwater profiling buoy device including a cable pull head hinge ring, temperature, salinity, and pressure measurement sensors, sensor protective covers, a buoyancy chamber, an underwater control unit, an inner oil bladder, a DC motor, an electric rotary valve, a check valve, a hydraulic motor, a rear end cover, an outer oil bladder, an oil bladder protective cover, and a watertight interface for the buoy. It can be used for buoyancy conversion and lifting control, and for measuring seawater temperature, salinity, and depth. This device is still driven by a motor, which generates noise during operation, making it easily detectable by sonar equipment and resulting in poor concealment. Furthermore, the device contains components such as a DC motor, an electric rotary valve, and a hydraulic motor, making it large in size and energy-intensive. Under certain energy conditions, the device's operational time is short.

[0004] However, the aforementioned publicly disclosed equipment is still driven by an electric motor, which generates noise during operation and is easily detected by sonar equipment, resulting in poor concealment. Furthermore, the device contains components such as DC motors, electric rotary valves, and hydraulic motors, making it large in size and consuming a lot of energy. Under certain energy conditions, the equipment can only be maintained for a short period of time. Summary of the Invention

One end of the second non-magnetic cylinder 5 extends at least partially into the cavity structure, and the other end is connected to and communicates with the second telescopic balloon 6.

The second permanent magnet 9 is disposed inside the second non-magnetic cylinder 5, and magnetic liquid is adsorbed on the second permanent magnet 9 so that the second permanent magnet 9 is stably suspended inside the second non-magnetic cylinder 5.

[0010] An electromagnetic control component, based on the first and second telescopic components, is disposed within the cavity structure to generate a magnetic field force to change the volume of the telescopic balloon, thereby changing the underwater buoyancy of the lifting device.

[0026] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0027] This application provides an underwater active lifting device based on magnetic fluid, such as... Figure 1 As shown, it includes:

[0028] The first outer shell 1 and the second outer shell 3 are made of non-magnetic material and together form a cavity structure. A first telescopic component and a second telescopic component are respectively provided on opposite sides of the cavity structure. In some embodiments, the first outer shell 1 and the second outer shell 3 are connected by screws 2 to form the cavity structure.

[0029] like Figure 1 As shown, the first telescopic component includes a first non-magnetic cylinder 13, a first telescopic balloon 15, and a first permanent magnet 14. One end of the first non-magnetic cylinder 13 extends at least partially into the cavity structure, and the other end is connected to and communicates with the first telescopic balloon 15. The portion of the cylinder connected to the first telescopic balloon 15 is filled with incompressible liquid. The first permanent magnet 14 is disposed inside the first non-magnetic cylinder 13, and magnetic liquid is adsorbed on the first permanent magnet 14 so that the first permanent magnet 14 is stably suspended inside the first non-magnetic cylinder 13.

[0030] like Figure 1 As shown, the second telescopic component includes a second non-magnetic cylinder 5, a second telescopic balloon 6, and a second permanent magnet 9. One end of the second non-magnetic cylinder 5 extends at least partially into the cavity structure, and the other end is connected to and communicates with the second telescopic balloon 6. The portion of the cylinder connected to the second telescopic balloon 6 is filled with incompressible liquid 7. The second permanent magnet 9 is disposed inside the second non-magnetic cylinder 5, and magnetic liquid is adsorbed on the second permanent magnet 9 so that the second permanent magnet 9 is stably suspended inside the second non-magnetic cylinder 5.

[0031] An electromagnetic control component, based on the first and second telescopic components, is disposed within the cavity structure to generate a magnetic field force to change the volume of the telescopic balloon, thereby changing the underwater buoyancy of the lifting device.

[0032] This application embodiment uses an electromagnetic control component to generate a magnetic field force based on the first and second telescopic components to change the volume of the telescopic balloon, thereby changing the underwater buoyancy of the lifting device. This can greatly reduce equipment energy consumption, increase equipment operating time, and improve equipment concealment.

[0033] In some embodiments, the magnetic liquid in the first non-magnetic cylinder 13 and the incompressible liquid are immiscible, as are the magnetic liquid in the second non-magnetic cylinder 5 and the incompressible liquid. For example, the magnetic liquid 8 may be an oil-based magnetic liquid, and the incompressible liquid 7 may be water, etc.

[0034] In some embodiments, the first telescopic component and the second telescopic component are symmetrically arranged based on the electromagnetic control component. In some embodiments, the magnetic poles of the first permanent magnet 14 and the second permanent magnet 9 are opposite each other. In some embodiments, sealing rings are provided between the first non-magnetic cylinder 13 and the first outer shell 1, and between the second non-magnetic cylinder 5 and the second outer shell 3.

[0035] As an assembly example, the first telescopic component can be mounted onto the first non-magnetic housing 1, and the connection is sealed with a first O-ring 4; similarly, the second telescopic component can be mounted onto the second non-magnetic housing 3, and the connection is sealed with a first O-ring 4; the mounting positions are symmetrical, and the magnetic poles of the first permanent magnet 14 and the second permanent magnet 9 are opposite each other. In some embodiments, the first permanent magnet 14 and the second permanent magnet 9 are permanent magnets composed of neodymium, iron, and boron materials.

[0036] The electromagnet component is then placed inside the non-magnetic housing, so that the two ends of the electromagnet are horizontally and concentrically aligned with the first permanent magnet 14 and the second permanent magnet 9. The first non-magnetic housing 1 and the second non-magnetic housing 3 are then fastened together using screws 2, and the connection is sealed using a second O-ring 12.

[0037] In some embodiments, the electromagnetic control component includes an excitation coil 11, an iron core 10, and a power control system 16. The excitation coil 11 is wound around the iron core 10 and connected to the power control system 16 to form an electromagnet.

[0038] The power control system can periodically energize the excitation coil, enabling the electromagnet to generate a magnetic force on the permanent magnet. The movement of the magnet changes the volume of the telescopic bladder, thereby changing the underwater buoyancy of the device to achieve an active lifting effect.

[0039] like Figure 2-4 As shown, the underwater active lifting device of this application embodiment can achieve automatic steering according to actual working conditions. When the two telescopic balloons are made of materials with different expansion coefficients, the same magnetic force changes the size of the balloons differently, thereby making the buoyancy on both sides different and achieving the purpose of steering.

[0040] The underwater active lifting device in this embodiment is driven by an electromagnet, which only requires switching the DC power switch on and off at regular intervals. The electromagnet does not generate any operating noise during operation, and the device is well concealed.

[0041] The underwater active lifting device in this embodiment uses a magnetic liquid to suspend and lubricate the permanent magnet. During operation, the permanent magnet moves with almost no resistance and noise, and there is almost no consumption when the magnetic force is converted into pressure, resulting in low energy consumption of the device.

[0042] This application also proposes a detection device, including the aforementioned underwater active lifting device based on magnetic liquid.

[0043] It should be noted that, in the embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0044] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.

[0045] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims.
