Patent number: 11739603Abstract: A core detection device of a coring instrument includes a base body and a core switch mechanism provided on the base body. The base body is provided with a core channel communicated with a core barrel. The core switch mechanism includes a detection portion, a connecting rod assembly and a travel switch which are sequentially arranged and connected along a length direction of the coring instrument. The detection portion is rotatably installed on the base body and one end thereof is extended into the core channel, so that a core passing through the core channel pushes the detection portion to rotate. The connecting rod assembly can be pulled by the rotating detection portion to trigger the travel switch to operate. The core switch mechanism adopts a slider-connecting rod structure, and the kinematic pairs are mainly a sliding pair and a rotating pair.Type: GrantFiled: February 18, 2021Date of Patent: August 29, 2023Assignees: China National Offshore Oil Corporation, China Oilfield Services LimitedInventors: Zhibin Tian, Lin Huang, Zanqing Wei, Shusheng Guo, Yongren Feng, Xingfang Wu, Tiemin Liu, Yong Jiang, Bin Gao, Peng Sun, Shiwei Zong, Jianyong Zhang, Aijun Zhang
