A frictional electrostatic power generation unit and its application in ocean energy harvesting

Abstract

The invention provides a friction type electrostatic power generation unit, comprising a first substrate and a second substrate that are alternately arranged, wherein the first substrate and the second substrate each have a coaxial central through hole, the straight rod is vertically inserted in the central through hole of the first substrate and the second substrate, the upper and lower sides ofthe substrate are provided with dielectric materials having opposite polarities. When the friction type electrostatic power generation unit is shaken, the straight rod pushes the second substrate, sothat relative movement occurs, and the dielectric materials between the first substrate and the second substrate are rubbed to generate electric charges, and the connection between the metal electrodes on the first substrate and the second substrate causes the electric charges to move, that is, to form a current, and convert the mechanical energy into electric energy. The friction type electrostatic power generation unit may be used in collecting marine energy for collecting the mechanical energy of seawater flow and converting the collected mechanical energy into electric energy for storage or power supply for the electric equipment, thereby providing a bran-new environmentally-friendly green energy for marine exploration equipment.

Description

technical field [0001] The invention relates to a friction electrostatic power generation unit and its application in ocean energy collection. Background technique [0002] The 21st century is the century of the ocean. The scale of ocean development is constantly expanding worldwide. The development of marine biological resources, the development of seabed mineral resources, the utilization of ocean space, and the protection of the ocean environment all have huge potential. Ocean observation instruments are one of the high-tech fields that are technology-intensive, knowledge-intensive, and capital-intensive, and are the backbone of the ocean information industry. However, the energy supply of electrical equipment limits the development of ocean development to a certain extent. Especially for equipment that needs to be in service for a long time, regular replacement of batteries or construction of wires will increase costs and cause a lot of inconvenience.
