Portable single-cabinet ball highly-integrated seabed electromagnetic device

Abstract

The invention provides a portable single-cabinet ball highly-integrated seabed electromagnetic device. The electromagnetic device integrated with the single cabinet ball and is provided with an externally-arranged magnetic probe, so magnetic disturbance on elements in a cabinet is effectively reduced and measurement data is more precise. The electromagnetic device is integrated with electric field measurement, magnetic field measurement and recording functions, so the number of devices is reduced. Electrode arms are telescopic, detachable and rotatable, and can be erected, unfolded and laid flat after being thrown into sea. The electromagnetic device can autonomously sink, float and is easily thrown and positioned. It is convenient for people to operate, maintenance and use the electromagnetic device to perform construction work without the assistance of large mechanical devices like cranes. The electromagnetic device has pressure-resisting, corrosion-resisting and waterproof functions, and is capable of easily sinking or floating and recyclable and stably working under the sea. Being integrated with common uncoupling mechanisms, the electromagnetic device is highly universal. Cost for scientific research is remarkably reduced. The electromagnetic device is highly precise and automatic and suitable for field of offshore oil, mineral exploration and research for marine geological structures.

Description

technical field [0001] The present invention relates to equipment for underwater operations or a device for salvaging or searching for underwater targets in IPC classification B63C, which belongs to the field of marine surveying and geophysical measurement for detecting instruments for submarine magnetic field signals, especially a portable single-chamber spherical high-integrated submarine Electromagnetic instrument. Background technique [0002] Obtaining geophysical information of the seabed requires comprehensive geophysical detection methods. But in our country, due to technical reasons, the electromagnetic method, nuclear radiation method and natural earthquake method have not entered the field of marine exploration for a long time. The difficulty is that the detectors used in these methods must sink to the seabed for measurement. The difference from land-based instruments is that underwater instruments need to solve key technologies such as sealing and pressure bear...

AI Technical Summary

Problems solved by technology

Since the electrode arm of the above-mentioned electric field meter cannot be bent, in the process of launching the instrument into the sea, it is necessary to use large-scale machinery such as a long-armed crane to assist in launching, and after a period of working time, it is necessary to carry out auxiliary recovery, which makes the construction work difficult.
