[0035] like Figures 1 to 4 As shown, the magnetic liquid sealed oscillating water column wave energy power generation device of this embodiment includes a power generation component 100 and a driving component 200. The power generation component 100 includes a first housing 110, a first magnetic structure 120 and a coil 130. The first housing 110 is provided with a first pipe 111. The first magnetic structure 120 includes a first magnetic member 121 and a magnetic liquid 122. The magnetic liquid 122 is adsorbed on the outer surface of the first magnetic member 121. The magnetic liquid 122 is sealed and filled between the first magnetic member 121 and the inner wall of the first pipe 111. The first magnetic structure 120 can be slidably arranged in the first pipe 111. The coil 130 is wound on the first housing 110, wherein the coil 130 can be arranged as a plurality of groups of wires wound in different directions. The driving component 200 includes a second housing 210, the second housing 210 is sealedly connected to the first housing 110, the second housing 210 is provided with a second pipe 211, one end of the second pipe 211 is connected to the first pipe 111, and the other end of the second pipe 211 can flow into the waves.

[0036] Based on the above design, in the magnetic liquid sealed oscillating water column wave energy power generation device of this embodiment, a closed space is formed between the first magnetic structure 120, the first shell 110, the second shell 210 and the waves. When the waves rise upward, the air volume in the closed space decreases and the air pressure increases, thereby pushing the first magnetic structure 120 to move upward; when the waves fall, the air volume in the closed space increases, the air pressure decreases, and the first magnetic structure 120 moves downward. The coil 130 is wound around the outside of the first shell 110. When the first magnetic structure 120 moves up and down, the first magnetic structure 120 and the coil 130 move relative to each other. According to the law of electromagnetic induction, the coil 130 cuts the magnetic flux lines to generate current, thereby realizing power generation using wave energy.

[0037] It can be understood that the magnetic liquid sealed oscillating water column wave energy power generation device uses air pressure to convert the wave fluctuations into the movement of the power generation component 100, avoiding the energy loss caused by the traditional mechanical transmission structure and improving the power conversion efficiency of the power generation device. The first magnetic structure 120 and the first shell 110 are slidably sealed by the magnetic liquid 122, and the magnetic liquid 122 is adsorbed on the first magnetic member 121 by magnetic attraction, which can avoid the leakage of the magnetic liquid 122, and can reduce the friction coefficient between the first magnetic structure 120 and the first shell 110, reduce the movement resistance, so that even under weak wave conditions, the relative movement between the first magnetic structure 120 and the first shell 110 can be achieved, thereby converting wave energy into electrical energy, improving the conversion power generation efficiency, and reducing the wear between the first magnetic structure 120 and the first shell 110, thereby increasing the service life of the power generation device.

[0038] Specifically, the first magnetic member 121 includes a plurality of yokes 1211 and a plurality of magnets 1212, wherein the plurality of magnets 1212 are arranged at intervals in the sliding direction of the first magnetic structure 120, and each yoke 1211 is connected between two adjacent magnets 1212, thereby enhancing the magnetic induction intensity and improving the power generation efficiency. In this embodiment, two magnets 1212 are provided, so as to ensure the power generation efficiency while avoiding the first magnetic member 121 from being affected by excessive gravity and sliding. In some other embodiments, three, four, etc. magnets 1212 may be provided.

[0039] Furthermore, the driving assembly 200 also includes an isolating member 220, a second magnetic structure 230 and a supporting member 240. The isolating member 220 is fixed between the first housing 110 and the second housing 210, and the isolating member 220 is provided with a through hole 221, and the through hole 221 is connected to the first pipe 111 and the second pipe 211. The second magnetic structure 230 is slidably arranged in the second pipe 211, and the second magnetic structure 230 repels the first magnetic structure 120. The supporting member 240 is located on the side of the second magnetic structure 230 away from the first magnetic structure 120 and is fixed to the second pipe 211. The supporting member 240 drives the second magnetic structure 230 to move toward the isolating member 220, and the second magnetic structure 230 can close the through hole 221.

[0040] The supporting force of the support member 240 on the second magnetic structure 230 is equal to the sum of the repulsive force of the first magnetic structure 120 on the second magnetic structure 230 and the gravity of the second magnetic structure 230, so that the second magnetic structure 230 is suspended in the second pipe 211. When the wave height reaches a certain height, in order to prevent the wave from entering the first pipe 111 and contaminating the magnetic liquid 122, the first magnetic structure 120 rises at this time, so that the distance between the first magnetic structure 120 and the second magnetic structure 230 increases, and the repulsive force between the first magnetic structure 120 and the second magnetic structure 230 decreases. The support member 240 can push the second magnetic structure 230 to move upward and close the through hole 221, thereby isolating the first pipe 111 and the second pipe 211, preventing the wave from entering the first pipe 111, ensuring the cleanliness of the first pipe 111, avoiding the contamination of the magnetic liquid 122, and extending the service life of the power generation device. When the wave height decreases, the first magnetic structure 120 falls down, pushing the second magnetic structure 230 away from the isolation member 220, and the first pipe 111 and the second pipe 211 resume the connection state.

Preferably, the through hole 221 is set as a tapered hole, and the aperture of the tapered hole gradually decreases from the second pipe 211 to the first pipe 111. The closure member 231 is provided with a tapered protrusion 2312, and the tapered surface of the protrusion 2312 can abut against the inner wall surface of the tapered hole, thereby improving the sealing effect of the isolation member 220 and the closure member 231.

[0044] Further, the second magnetic structure 230 also includes a rolling body 233, which is connected to the peripheral side of the closing member 231 and abuts against the inner wall of the second pipe 211.

In addition, the third housing 310 can also prevent the influence of external impurities on the first magnetic structure 120, and improve the performance and life of the power generation device.
