According to the invention, underwater water flow kinetic energy can be fully utilized, kinetic energy is rapidly and efficiently converted into electric energy, the self-powered requirements of equipment such as an underwater detector and the like are met, and a power basis is provided for deep-sea long-range navigation detection.

Description

technical field [0001] The invention relates to a beam-slab composite underwater power generation device based on flexoelectric effect and a method thereof, belonging to the technical field of underwater power generation. Background technique [0002] The ocean is an important support for the country's sustainable development, and it is imminent to move towards the deep sea. However, my country's detection capabilities for the deep sea with huge strategic resources are still quite limited. Unmanned underwater detection vehicle is a small intelligent equipment that can autonomously navigate to a designated area for military or civilian tasks such as information collection, environmental monitoring, intelligence investigation, and remote control operations. Due to the limited size of the detection vehicle, its conventional energy mode Powered by batteries, it is difficult for the carried batteries to continuously supply detection for a long time, and it is necessary to charge ...
