The device has the advantages that the device is simple in structure, high in reliability, free of sliding / rotating nodes, low in cost, high in efficiency, long in service life and the like, and the economy and the engineering applicability of the flow-induced vibration power generation device are enhanced.

Description

technical field [0001] The invention relates to the field of new energy power generation equipment and fluid mechanics, and more particularly, to a flow-induced vibration power generation device based on a deformable support. Background technique [0002] Nowadays, with the rapid development of the global economy, fossil fuel resources are increasingly depleted, and the environmental pollution caused by them is becoming more and more serious. The development and utilization of clean and renewable energy has become a strategic choice for countries in the world today. Among the many clean energy sources, ocean current energy has attracted more and more attention from the scientific and engineering circles for its efficient development and utilization due to its advantages of large scale, stable flow, and wide distribution. According to statistics, the global available ocean current energy is as high as 5 million megawatts. China's ocean currents are also very rich, with the T...

Problems solved by technology

However, the shortcomings of the VIVACE ocean current energy utilization device are also very prominent

1) There are too many mechanical transmission parts, because marine biological debris is attached to the mechanical transmission parts, resulting in increased frictional resistance of the transmission parts, which reduces the energy conversion coefficient of the VIVACE sea current energy utilization device; 2) It is difficult to prevent underwater corrosion, because With mechanical transmission, simple anti-corrosion coating protection cannot be used at the sliding / rotating connection nodes of components; 3) Additional support structure, VIVACE ocean current energy utilization device module requires two additional columns to support the columns suspended on it, so The cost is high, and the column has a hindering effect on the ocean current, which reduces the energy conversion coefficient of the VIVACE ocean current energy utilization device

These defects limit the economy and practicability of the VIVACE ocean current energy utilization device
