Problems solved by technology

The seabed sediment sampling pipe is usually composed of several sampling pipe sections, but when the sampling pipe penetrates into the seabed sediment, the sampling pipe and the sediment will separate adjacent sampling pipe sections under the action of friction torque, resulting in damage to the structure of the sampling pipe. eventually lead to sampling failure

Abstract

A synchronous sampling pipe with multi-section connection comprises positioning and connecting blocks, a positioning and connecting plate, fixing pieces and two or more sampling pipe sections. The inner side of one end of each sampling pipe section is of an internal thread structure, the other end of each sampling pipe section is of an external thread structure, the synchronous sampling pipe is composed of the sampling pipe sections, and the adjacent sampling pipe sections are fastened through the threads on the inner sides of the ends of the sampling pipe sections. The positioning and connecting blocks are arranged at the ends of the adjacent sampling pipe sections respectively, and the positioning and connecting plate is arranged above the adjacent positioning and connecting blocks and is fixed to the positioning and connecting blocks through the fixing pieces. According to the synchronous sampling pipe with multi-section connection, it is guaranteed that wire pipe connecting lines coincide to guarantee that a wire passes through safely and smoothly; in the sampling process, the sampling pipe sections rotate and shift due to penetration force and friction force, and the positioning and connecting plate is fastened to the two connected sampling pipe sections through the connecting bolts to prevent the sampling pipe sections from shifting relatively.

Description

technical field [0001] The invention relates to the technical field of marine monitoring, in particular to a synchronous sampling pipe with multi-section connections and a seabed sediment sampler using the same. Background technique [0002] The sedimentary state and structure of the seabed are complex and rich, and the types of sediments are diverse. An in-depth understanding of the acoustic characteristics of seabed sediments has always been one of the key scientific issues to improve the accuracy of acoustic telemetry to detect the ocean. The seabed sediment sampling pipe is usually composed of several sampling pipe sections, but when the sampling pipe penetrates into the seabed sediment, the sampling pipe and the sediment will separate adjacent sampling pipe sections under the action of friction torque, resulting in damage to the structure of the sampling pipe. Eventually lead to sampling failure. Contents of the invention [0003] The object of the present invention ...
