Embodiment

[0025]During on-site arrangement, the devices of the present invention can be arranged in series on the outer wall of the riser 1 at a certain interval as required. During installation, the helical coil 7 is firstly wound around the outer wall of the standpipe 1 in a helical ascending shape along the axial direction of the standpipe 1, and at the same time, a conductive ring coil 10 is respectively placed on the upper and lower ends of the standpipe 1. The conductive ring coil 10 and the helical coil 7 are connected by a connecting wire 11, and the ring coil fixing piece 14 of each conductive ring coil 10 is clamped and fixed on the stand by the clamp 15 on the fixing piece and the lower clamp 16 of the fixing piece. Tube 1 outside the wall. Next, the coil sleeve 2 is placed outside the helical coil 7 and the conductive circular coil 10 . A rotary bearing is respectively set on the upper and lower ends of the coil sleeve 2, and the blade outer sleeve 6 is set on the upper and...

Abstract

The invention relates to a propeller type synchronous power generating and vibration suppression device and method with piezoelectric panel. The device comprises a rotating module and a conductive module. The conductive module comprises a spiral coil, a conductive ring coil, a ring coil fixing plate, a fixed plate upper clamp, a fixing plate lower clamp, connecting conductors, output conductors and a coil sleeve. The rotating module comprises a blade outer sleeve, a rotating bearing, an embedded magnetic tape blade, a piezoelectric panel, piezoelectric panel conductors and a rotating clamping hole. The rotating module rotates around a vertical pipe under the flushing of sea waves to achieve the cutting of magnetic induction lines and the deformation of the piezoelectric panel simultaneously to generate electric current. At the same time, when the embedded magnetic tape blade and the piezoelectric panel rotate, the flow field surrounding the vertical pipe is undermined, the separation of boundary layers and the generation of vortexes are interfered, therefore the vortex induced vibration is inhibited, the device and method hit two birds with one stone.

Description

technical field [0001] The invention belongs to the technical field of marine new energy utilization and riser facility laying, and specifically relates to a propeller-type synchronous power generation and vibration suppression device and method with piezoelectric sheets installed. Background technique [0002] Today, with the rapid economic and social development, the demand for energy is rising steadily, while the proven reserves of non-renewable energy such as oil and natural gas are decreasing year by year, making the contradiction between energy supply and demand extremely prominent. Therefore, seeking energy from the ocean, developing offshore oil and gas resources and utilizing ocean energy have become important breakthroughs for countries to solve the energy crisis. The ocean stores huge oil and gas resources, and also contains huge energy. More importantly, ocean energy is not only clean and environmentally friendly, but also an inexhaustible renewable energy source...
