Patent number: 12049935Abstract: A liquid composite spring and a method for adjusting stiffness and damping property of the liquid composite spring such that the liquid composite spring includes an outer sleeve; a core shaft arranged around an upper portion of the outer sleeve. An upper portion of the core shaft is located inside the outer sleeve, while a lower portion extends out of the outer sleeve; an upper liquid chamber formed in an upper space inside the outer sleeve and having a lower portion connected to a top end of the core shaft; and a lower liquid chamber formed in a lower space inside the outer sleeve and connected with the core shaft. The core shaft has a damping flow channel arranged therein, for communicating liquid in the upper liquid chamber with liquid in the lower liquid chamber. The liquid composite spring can provide vibration-reducing effect and change stiffness and damping effect.Type: GrantFiled: September 4, 2020Date of Patent: July 30, 2024Assignee: ZHUZHOU TIMES NEW MATERIAL TECHNOLOGY CO., LTDInventors: Xingwu Ding, Jiling Bu, Yimeng Li, Guijie Liu, Feng Wang, Zhangyang Xia

Publication number: 20210009248Abstract: Disclosed is a pile leg walking type manganese nodule mining robot. The robot includes a body, a pile walking mechanism, a vector propulsive mechanism, a negative pressure suction mechanism and a manganese nodule cutter suction mechanism. The invention involves a stable and efficient deep-sea mining robot which can complete the mining task on the geological layer where the manganese nodule are located, and effectively protects the marine life and living environment in the deep-sea mining area. The existence environment of manganese nodule is also protected. After mining, the regeneration environment of living or other resources on the deep-sea floor will not be affected, thus greatly resolving the sharp contradiction between resource exploitation and environmental protection.Type: ApplicationFiled: September 28, 2020Publication date: January 14, 2021Inventors: Guijie LIU, Wei PAN, Dingxin LENG, Yingchun XIE, Xiaojie TIAN, Honghui WANG
