Title:
SAMPLING DRILLING IMPLEMENT USED FOR SEABED EXPLORATION, AND METHOD FOR USE
Document Type and Number:
WIPO Patent Application WO/2021/128072
Kind Code:
A1
Abstract:
Provided are a sampling drilling implement used for seabed exploration, and a method for use; in view of the problems of poor stability of existing sampling drilling implements for seabed exploration, which cannot guarantee accuracy of sampling, it being necessary to manually pull up the sampling drilling implement for seabed exploration in order to remove the drill bit from the surface of the seabed, and the large amount of manual labor required, the following solution is proposed: comprising a mounting plate (1); the two ends of the bottom wall of the mounting plate (1) are fixed with vertical support columns (6); the outer rings of the two support columns (6) are movably sleeved with a horizontal lifting/lowering plate (7); the bottom end of the support column (6) extends below the lifting/lowering plate (7) and is fixedly connected with a support block (8); the middle position of the lifting/lowering plate (7) is rotationally sleeved with a vertical rotary shaft (10) by means of a bearing; the bottom end of the rotary shaft (10) extends below the lifting/lowering plate (7) and is fixedly connected with a drill bit (11); the drilling implement has a novel design, is simple to operate, and is highly stable when operating; it can ensure accuracy of sampling, the drill bit can be automatically separated from the surface of the seabed, and the amount of manual labor is small.
