Energy harvesting power generator for marine riser

Abstract

The invention provides an energy harvesting power generator for a marine riser. The energy harvesting power generator for the marine riser comprises a flexible film type energy harvesting power supply structure, wherein the marine riser is externally wrapped in the flexible film type energy harvesting power supply structure, and multiple piezoelectric units are packaged in the flexible film type energy harvesting power supply structure. Enough electrical energy for a detection system of a marine pipeline and a detection data transmission system can be completely provided through electrical energy generated by the energy harvesting power generator, an electrical energy storage device is further comprised, when the generated electrical energy is in surplus, extra electrical energy can be stored, and continuous system power supply can be guaranteed. According to the energy harvesting power generator, wireless pipeline detection in the special marine environment and wireless detection data transmission can be directly supported, and the energy harvesting power generator represents important innovation of the underwater structure detection technology.

Description

technical field [0001] The invention relates to an energy capture power generation device for an ocean riser. Background technique [0002] Oil and natural gas are important strategic resources related to national economic and social development. my country's marine recoverable oil reserves account for almost one-third of all recoverable reserves, and will be the top priority of the national energy strategy for a long time to come. . Submarine pipeline is the most important and fastest, economical and reliable transportation method for offshore oil and gas resources. The service environment of submarine pipelines is extreme. With the continuous increase of its service time, defects such as corrosion and welds seriously affect the safety of pipelines and become the main cause of pipeline accidents. Therefore, the use of inspection tools to conduct safety inspections on submarine pipelines has become a guarantee An important means for the safe operation of pipelines. In rece...
