Abstract

The invention provides a carbon fiber electric field sensor structure and a preparation method. The structure is characterized in that a carbon fiber beam senses change of electric field in the surrounding environment; signals are collected via the carbon fiber beam and induction signals are exported through a lead. The electric field sensor structure mainly comprises five parts including the carbon fiber beam, a carbon fiber solidification cavity, a watertight shade, a micro-pore pipe and a bottom cover. Since one end of the carbon fiber beam is solidified in the solidification cavity with epoxy resin, the cross section of the carbon fiber beam is coated with a layer of metal after being polished and then the lead is welded to the surface of the metal coating layer. The welding spot is sealed by utilizing the watertight shade filled with epoxy resin and the lead is led out through a watertight joint. The micro-pore pipe is threaded to the bottom of the solidification cavity and is filled with a filler for fixing the carbon fiber beam. The electric field sensor has good range stability, wide frequency domain signal response and comparatively low noise level.

Description

technical field [0001] The invention relates to an electric field sensor structure in the field of ocean electric field monitoring, in particular to a structure and a preparation method of a carbon fiber electric field sensor for monitoring ocean electric field. Background technique [0002] With the advancement of science and technology, the measurement of electric field signals is increasingly favored by scientists in the process of ocean development and utilization. The electric field signal has been applied in the detection of the physical electric field of the ship and the geological structure of the seabed. [0003] Since ships are mostly composed of different metal structures, different types of metals will produce different corrosion potentials. When two different metals are immersed in seawater together, a corrosion circuit will be formed and a corrosion current will be generated. In addition, in order to prevent corrosion of ships, it is necessary to manually appl...
