Brush assembly and pipe cleaning robot equipped with the same

This technology secures the adhesion of a brush assembly by combining link members, which feature variable bending angles via a hinge structure to match the inner wall profile of a pipe, with leaf spring-based elastic members attached to the sides of the link members to prevent twisting and provide restorative force.

When cleaning pipes with varying diameters or bends, conventional fixed-brush structures suffer from reduced adhesion to the inner wall, leading to low cleaning efficiency and difficulty in removing debris.

This technology allows the link members to bend and deform according to the pipe's inner wall environment, while using elastic members (leaf springs) to prevent twisting at the hinge and ensure natural restoration to the original state. Furthermore, by connecting multiple link members with hinge axes and connecting components, it enables omnidirectional pipe cleaning. Applicable to industrial robots and automated systems, it improves cleaning efficiency and effectiveness in deep, narrow transport lines where high levels of toxic gas residue are likely.

Key Features:

• A connecting member that links the common hinge axis of at least two first link members with the common hinge axis of at least two second link members
• At least two second link members spaced apart from each other in a second direction different from a first direction
• An elastic member mounted on the side of the link member that deforms according to the bending angle of the link member
• At least two first link members spaced apart from each other in a first direction
