Problems solved by technology
[0006] To sum up, the existing wave energy conversion devices all have the same limitations, and have failed to make breakthroughs and solutions fundamentally. They all have the following defects: 1) Due to the harsh operating environment of the ocean, many devices not only cannot operate in the designed state Power generation, even in bad weather and wind and waves, cannot effectively protect itself and is easily damaged; 2) The mechanical conversion structure is complex and the system reliability is poor; 3) The effective utilization coefficient of wave energy is low; 4) Many power generation principles are based on On the basis of a stable offshore platform, the cost is very high

Embodiment approach
[0029] The implementation mode of the embodiment of the present invention is as follows:
[0030] After the flexible magnetic fluid wave power generation device of the embodiment of the present invention is folded, it is transported by a workboat to the sea area where it is deployed, and then flattened on the sea surface, and the laminated body of the flexible magnet fixing part and the medium container is aligned with the direction of the wave through the rope. The two sides are connected with the working boat. With the assistance of the floating body and the drive of the wave energy, the superimposed body of the flexible magnet fixing part and the medium container undulates with the waves, so that the liquid magnetic fluid is formed by the permanent magnet under the action of the pressure wave inside the medium container. The magnetic field space of the Halbach surface array cuts the magnetic field line movement, thereby converting the low-density and unstable wave energy int...

The invention discloses a flexible magnetic fluid wave energy generation device, relates to the technical field of ocean energy, and aims to improve viability and the wave energy utilization coefficient and reduce cost. The device comprises a permanent magnet and a medium container, wherein a cavity of the medium container is filled with conductive liquid magnetic fluid; the device also comprises a sheet-shaped flexible magnet fixing component capable of floating on water; the flexible magnet fixing component is formed by jointing multiple magnetic yokes in a spreading manner; the magnetic yokes are articulated with one another and gaps are reserved; multiple permanents are used and fixed in corresponding magnetic yokes respectively; the medium container is a sheet-shaped flexible swim bladder capable of floating on water, and is overlapped with the flexible magnet fixing component in an overlapping manner; the cavity of the medium container is entirely sealed and is waterproof; an electrode is fixed at each of the two ends of the medium container; and the two electrodes are both electrically connected with the liquid magnetic fluid in the medium container. The device provided by the invention can be spread on the sea surface without using a stabilizing platform.
Description
technical field [0001] The invention relates to ocean energy technology, in particular to the technology of a flexible magnetic fluid wave energy generating device. Background technique [0002] The theoretical value of wave energy in the world is about 10 9 kW level. The distribution of wave energy is extremely wide. If it is effectively developed and utilized, it will not only help solve the energy shortage, climate change and environmental protection problems faced by society, but also greatly enhance the development ability of marine resources. The deep sea area far away from the land contains more and richer wave energy resources than the coastal base area, which is also the mission requirement for the development of blue oceans. However, wave power generation in remote sea areas needs to overcome many technical difficulties and harsh environmental problems. [0003] With the development of society and economy, along with the increasingly severe energy pressure and t...
