A biomimetic sucker-setae composite structure for wet and slippery rough walls

Abstract

The invention discloses a bionic sucker-bristle composite structure for wet and slippery rough walls. The bottom of the flange of the body is provided with multiple submillimeter-scale protrusions, each sub-millimeter-scale protrusion is provided with multiple micron-scale bristles at the bottom, each micron-scale bristle is provided with multiple nano-scale fluff at the bottom, and the suction cup body is embedded with There is a shape memory alloy driving structure. By energizing the shape memory alloy driving structure, the shape memory alloy driving structure is deformed due to temperature changes, thereby driving the deformation of the suction cup body, causing the volume of the concave cavity of the suction cup body to change, and then adjusting the suction cup body. of adsorption. The invention has the advantages of realizing stable adsorption on wet and slippery rough wall surfaces. And can realize self-adsorption and desorption.

Description

technical field [0001] The invention relates to the technical field of wall-climbing robots, in particular to a bionic suction cup-bristle composite structure for wet and slippery rough walls. Background technique [0002] The detection of wet and rough walls has always been a technical problem in related industries, especially the inner walls of small tanks and pipelines that are difficult or unsuitable for humans to enter, such as: transformers, oil and gas tanks, power station cooling pipes, etc. Inner wall cleaning and inspection tasks. With the development of robot technology, intelligent mobile robots have been widely used in construction, investigation, security, service and other fields. As a mobile robot with the ability to walk and stay on the wall in three-dimensional space, the wall-climbing robot can replace humans to carry out operations on steep walls, effectively improving operation efficiency and ensuring operation safety. Traditional wall-climbing robots u...

Problems solved by technology

However, these traditional wall-climbing robots are prone to slipping when they are in contact with slippery and rough walls, and it is difficult to work on slippery and rough walls.

At present, the wall-climbing robot technology designed to detect wet and slippery walls in small and confined spaces is mainly limited by the adsorption device, and there is no better solution.
