Deep sea in-situ near sea bottom profile observation device

Abstract

The invention relates to a deep sea in-situ near sea bottom profile observation device, which belongs to the field of sea bottom observation devices. The observation device comprises a sea bottom in-situ observation platform frame fixed to a sea bottom, wherein parallel guide frames are fixed to the frame and are vertical to the plane direction of the sea bottom; an upper motion platform is arranged between the guide frames and moves up and down along the guide frames; the upper motion platform is fixedly connected with the tail end of an output shaft of an upper drive motor; the upper drive motor is fixed to the frame; small guide frames are fixedly connected to the bottom of the upper motion platform, positioned on the inner sides of the guide frames respectively, parallel to the guide frames and move up and down along the guide frames; a lower motion platform is arranged between the small guide frames and moves up and down along the small guide frames; a bracket is fixedly connected between the small guide frames and provided with a lower drive motor; the tail end of the output shaft of the lower drive motor is fixedly connected with the lower motion platform; and the lower motion platform is provided with a measuring transducer. High spatial resolution detection capability of deep sea bottom environmental parameter change can be improved and high-accuracy profile measurement of the environmental parameter of a sea bottom boundary layer is realized.

Description

technical field [0001] The invention relates to a seabed observation device, in particular to a deep sea in-situ near seabed profile observation device. Background technique [0002] The deep seabed, which occupies 50% of the earth's area, has increasingly become a strategic area of ​​concern to all countries in the world due to its vast space, rich resources and special political status. It is the fundamental interest of the country to accelerate the improvement of deep sea resource exploration, research and development capabilities. The deep-sea seabed boundary layer is the most complex area where physical, chemical and biological processes are coupled and interacted. , the key area for predicting the long-term changes of the earth system. However, at present, human beings have very limited understanding of the deep seabed boundary layer, especially its special contribution to seabed mineralization, sedimentation and biological processes, and many aspects are still blank. ...
