Patent number: 11585174Abstract: A hydraulic propulsion horizontal directional coring device includes a casing pipe, a coring tube assembly and a conversion adapter. Both the casing pipe and the coring tube assembly coaxially set within the casing pipe are tubular. The conversion adapter, having a cylindrical structure fitted with the casing pipe, is coaxially set at a back side of the coring tube assembly and is slidably connected with an inner wall of the casing pipe. Under an action of an external force, the conversion adapter pushes the coring tube assembly to move along an axial direction of the casing pipe till a front end of the coring tube assembly extends out of or retracts into the casing pipe. The conversion adapter and the coring tube assembly have a first channel and a second channel axially provided therein, respectively. The first channel is connected with the second channel.Type: GrantFiled: November 1, 2021Date of Patent: February 21, 2023Assignee: China University of Geosciences (Wuhan)Inventors: Xuefeng Yan, Cong Zeng, Peng Zhang
