Embodiment

[0040] When installing the device of the present invention, first install the rotating bearing 2, determine the distance between the upper and lower rotating bearings 2 according to the height of the embedded magnet wire type water baffle 8, and respectively set the upper and lower rotating bearings 2 on the marine riser from both sides 1 and fastened with bolts.

[0041] Then, embed the bar magnet 10 in the embedded magnet wire type water baffle 8, fix it with clamp nuts, put the fishtail swing plate 11 on the slender round rod 16 of the embedded magnet wire type water baffle 8, and use The baffle caps the ends and secures them with screws. Insert the embedded magnet wire type water baffle 8 installed with the bar magnet 10 and the fishtail swing plate 11 into the water baffle bayonet 15 of the inner groove snap ring 4, and fix it with screws.

[0042] Then carry out the assembly of a single wing module, a semi-cylindrical magnet 6 and an orifice 7 are inserted in the semici...

Abstract

The invention relates to a device and a method for magnetic power generation and vortex-induced vibration suppression of imitating the swimming, turning and swinging of a fish. The device is composedof a main body module and a flank module. The main body module comprises a flow facing snap ring, an inner groove snap ring, a rotary bearing, a strip magnet, an embedded magnet wire type water stop plate and a fishtail swing plate. The flank module comprises a swing arm, a semi-cylinder magnet and an orifice plate. According to the device for magnetic power generation and vortex-induced vibrationsuppression of imitating the swimming, turning and swinging of the fish, under the common action that the semi-cylinder magnet and the swing arm slide and reciprocate, the orifice plate breaks the coming flow, the fishtail swing plate breaks the tail vortex street, and the embedded magnet wire type water stop plate divides the flow space and adjusts the flow direction, the formation and development of the vortex are suppressed, and the vortex-induced vibration suppression without energy consumption is achieved; and an induced current is generated in the circuit formed by induction wires, so that the conversion of marine current energy is achieved while the vortex-induced vibration is suppressed.

Description

technical field [0001] The invention belongs to the technical field of marine new energy utilization and riser facility laying, and in particular relates to a magnetic power generation and vortex-induced vibration suppression device and method imitating fish swimming and pendulum. Background technique [0002] Today, with the rapid economic development, energy demand continues to rise, but traditional energy such as oil and natural gas are non-renewable resources, and their resource reserves are declining year by year. Humans urgently need a renewable and clean energy. Therefore, people invariably turn their attention to the vast blue sea, and the development of marine energy has become a key breakthrough for countries to solve the energy crisis. The ocean contains huge resources, not only the rich oil and gas resources buried in the ocean, but also clean energy such as wind energy, wave energy, tidal current energy, ocean current energy, temperature difference energy and sa...
