Title: Guodong Yi: Inventor of Drilling and Mechanical Safety Innovations

Introduction

Guodong Yi is an inventor associated with Hangzhou, China, and Zhejiang University. His work includes inventions in drilling equipment and mechanical structures. The provided information lists 3 patents associated with him.

Latest Patents

One of Yi’s latest patents is the “Multi-impeller passive-rotating-stirring-type rotary drilling rig for open caissons.” The design uses four impellers positioned around a hollow main drill pipe. As the rig drills, the impellers contact the borehole wall and rotate passively in the direction opposite to the drill bit. This action helps mix silt and water to form mud during drilling.

Another listed patent is the “Variable-diameter full-support mandrel structure with slider-type cross section for preventing reverse rotation of ratchet wheel.” It features a movable mandrel segment connected to a straight shank by a quick-disconnect universal joint. A linkage system connects components mounted around the rotating shaft to slider components in an outer ring. The sliders have a Z-shaped structure made from two layers of arc blocks, and the assembly is designed to prevent a ratchet wheel from rotating backward.

Career Highlights

Yi’s listed inventions address practical engineering challenges, including improving the mixing action of drilling equipment and preventing reverse rotation in a mechanical assembly. His association with Zhejiang University places his work within a university research and innovation setting.
