A high-sensitivity bionic lateral water flow and water pressure sensing array structure

Abstract

The invention discloses a high-sensitivity bionic lateral line water flow and water pressure sensing array structure. Part of the ciliary structure on the base body is nested in the cavity of the bracket, and the bionic sensitive top covers and connects the part of the ciliary structure on the base body and the bracket. Five bionic sensors are respectively attached to the top of the upper cover of the pipeline and in the cavity of the bionic local shrinkage pipeline, and they are distributed in an array along the length direction, correspondingly forming the bionic surface neuromast sensing array and the bionic pipeline neuromast sensing array, which are used to sense water flow respectively Variations and differential pressure gradients. The upper cover plate of the pipeline is provided with a through hole along its length direction, and the bottom of the upper cover plate of the pipeline is combined with the upper part of the bionic partial shrinkage pipeline through a waterproof sealant. It can effectively increase the local flow velocity, and the combination of the bionic sensitive top structure and the tree crown skeleton framework by using porous hydrogel materials with strong water absorption can effectively improve the interaction force between water and the sensing unit structure to enhance its sensing response signal, thereby Effectively improve its detection sensitivity and accuracy.

Description

technical field [0001] The invention belongs to the technical field of underwater sensors, in particular to a high-sensitivity bionic side-line water flow and pressure sensing array. Background technique [0002] The continuous advancement of underwater equipment technology and the complexity of its underwater environment have strengthened the need for underwater equipment to perceive the environment. Traditional underwater vehicle or underwater robot detection methods have some defects, such as sonar detection The detection method is prone to blind spots, while the camera and laser detection methods are more likely to be constrained by vision, and the perception signal is relatively single, which makes it impossible to perceive short-range disturbances, let alone judge changes in the surrounding environment. However, underwater detection Technology is also an important means of equipment required for naval warfare. [0003] After hundreds of millions of years of evolution,...
