The invention provides a film for friction nanometer power generation using mechanical vibration. The film is based on a marine riser or a mooring cable, comprises a plurality of friction nano power generation units, and can capture vibration of the marine riser or the mooring cable so as to absorb mechanical energy and convert the mechanical energy into electric energy. The generated electric energy can be supplied to electric equipment such as ancillary facilities of marine risers or mooring cables, so that distributed health monitoring of the marine risers or the mooring cables can obtain energy supply, and the electric energy can also be supplied to living equipment to provide energy supply required by daily activities in the open sea. The film comprises a flexible insulating protection layer, so the internal nano friction power generation unit is protected, the service life is prolonged, the effect of better developing and utilizing blue energy is achieved, and a certain protection effect on the internal structure of the marine riser or mooring cable can be achieved.
Description
technical field [0001] The invention relates to the technical field of energy harvesting based on the principle of triboelectric power generation, in particular to a triboelectric nano power generation film using mechanical vibration of marine risers or mooring cables. Background technique [0002] With the increasing demand for energy, human beings began to move towards the ocean. The continuous advancement of offshore oil production platforms to the deep sea, numerous offshore wind turbines, and even the emergence of deep-sea farms mean that distributed health monitoring of slender structures such as marine risers or mooring cables in extreme environments is particularly important. However, the marine environment Complicated and inconvenient to supply energy to the monitoring device. Moreover, energy supply in distant sea areas is not convenient. [0003] Since 2012, the principle and technology of nano triboelectric power generation have developed rapidly and are widely...
