Abstract

The invention discloses a beam-slab composite underwater power generation device based on the flexoelectric effect and a method thereof, aiming at solving the technical problems in the prior art that the underwater power generation device has low efficiency, complex structure and is not suitable for deep-sea exploration. It includes: at least one set of upper power generation unit, lower power generation unit, and electric energy conversion unit; the upper power generation unit has the same structure as the lower power generation unit, and is connected through elastic components; the upper power generation unit includes a fixed seat, a flexible electric cantilever beam, Insulated rigid substrate, flex electric plate, electrode copper sheet and insulating film, flex electric cantilever beam and insulating rigid substrate are installed vertically on the fixed seat, and flex electric plate is installed between flex electric cantilever beam and insulating rigid substrate between. The invention can make full use of the kinetic energy of underwater water, quickly and efficiently convert the kinetic energy into electric energy, meet the self-power supply requirements of underwater detectors and other equipment, and provide the electric power basis for deep-sea long-distance voyage 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 ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems of low efficiency, complex structure and unsuitability for deep-sea exploration in existing underwater power generation devices, the present invention proposes a beam-slab composite underwater power generation device and its method based on flexoelectric effect. It can cause the deformation of the flexural material, and the strain gradient and polarization phenomenon will occur inside the material, forming a potential difference, and then outputting electric energy to realize high-efficiency underwater power generation
