Three-component magnetic field measurement device for deep water pressure resistance

Abstract

The invention discloses a deep-water pressure-resistant three-component magnetic field measuring device, which relates to the field of marine survey and includes an instrument cabin, a frame base, a first support base, and a second support base. The center of the instrument cabin base included in the instrument cabin is provided with an assembly base ;The frame base includes a ring-mounted top ring body and a bottom ring body, the top ring body and the bottom ring body are connected by a vertically arranged first connecting rod body, a bearing ring is coaxially arranged in the bottom ring body, and the second connecting rod body connects the bearing ring and the bottom ring body Ring body; the first support rod included in the first support base is vertically arranged on the top of the instrument cabin, and a plurality of connecting ropes are passed around the first support rod body to connect the top ring body, and floating balls are arranged around the middle part of the first support rod body; the second support base The included second support rod is vertically arranged at the bottom of the instrument cabin, and flexible strips are arranged around the outer side of the second support rod body to connect the inner ring of the bearing ring. It solves the problems of low stability of the existing technology, insufficient protection of the instrument cabin and high overall power consumption.

Description

Technical field [0001] The present invention belongs to the field of ocean surveys, and in particular, the present invention relates to a deep water withstand voltage three-component magnetic field measuring device. Background technique [0002] The description of this section provides only background information related to the disclosure of this application, and does not constitute a prior art. [0003] Ocean electromagnetic exploration is one of the main marine geophysical detection methods. It is suitable for the region of the seismic method, which is unlikely to distinguish and has an advantageous area, such as the carbonate reef, rock, volcanic rock cover, seabed permanent frozen soil, etc. . Due to the complexity and high risks of the exploration of the sea area, it is an important means to become a market resource survey in developed countries with comprehensive geophysical collection to reduce risks. The combination of electromagnetic exploration and seismic exploration i...
