Bionic sucker-bristle composite structure for slippery rough wall surface

Abstract

The invention discloses a bionic sucker-bristle composite structure for a slippery rough wall surface. The structure comprises a suction cup body, the center of the bottom of the sucker body is recessed to form a cavity, a circle of flange is formed at the part of the sucker body at the periphery of the cavity; a plurality of submillimeter-level bulges are arranged at the bottom of the flange of the sucker body; a plurality of micron-sized bristles are arranged at the bottom of each submillimeter-sized bulge; a plurality of nano-scale fluff is arranged at the bottom of each micron-scale bristle; a shape memory alloy driving structure is embedded in the suction cup body, the shape memory alloy driving structure is powered on, so that the shape memory alloy driving structure deforms due to temperature changes, the suction cup body is driven to deform, the size of the cavity of the suction cup body is changed, and then the adsorption force of the suction cup body is adjusted. The bionic sucker-bristle composite structure has the advantage that stable adsorption on the slippery rough wall surface is realized. Autonomous adsorption and desorption can be realized.

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.
