Drilling robot support for deep sea sampling

Abstract

The invention provides a drilling robot support for deep sea sampling. The drilling robot support comprises a fixing device, a leveling device and a counter-force supporting device. The fixing device is composed of a robot outer barrel, a fixing ring and a plurality of fixing clamping plates and used for fixing and carrying a drilling robot. The leveling device is composed of a supporting rod, a connecting rod and an electric cylinder and used for adjusting the gesture of the drilling robot after the support lands in the deep sea, so as to make a drill bit of the drilling robot perpendicular to the horizontal plane to perform drilling operation. The counter-force supporting device is composed of a propulsion device, a self-expansion device and a drill rod and connected to the tail end of the supporting rod. Compared with the prior art, the drilling robot support can overcome the shortcomings of a drilling vessel and a drilling platform and have good flexibility and operation performance and can further provide effects of positioning, leveling and supporting and the like for the deep sea sampling drilling robot. In addition, all the process of the deep sea sampling drilling robot and the drilling robot support is automatic operation, and communication is performed with a working ship in real time through wireless signals.

Description

technical field [0001] The invention relates to geological drilling equipment, in particular to a drilling robot support for deep sea sampling. Background technique [0002] The total area of ​​the earth's surface is about 510 million square kilometers, about 70% of which is ocean. The development and utilization of marine resources have been paid more and more attention by various countries, and the related marine resource exploration industry has become the core strategic field of many countries. The depth of the ocean can range from a few meters in the shallow sea to thousands of meters in the deep sea. Deep sea exploration and sampling are technically difficult, especially the equipment used for sampling is demanding, which is a major bottleneck in the exploration of marine resources. The deep sea is often rich in resources, and exploration is of great significance, and it is a hot spot in marine resource exploration. From the current point of view, the current status ...

AI Technical Summary

Problems solved by technology

From the current point of view, the current status of deep-sea drilling and sampling technology at home and abroad is that domestic deep-sea drilling starts late and develops slowly, the reliability of submarine drilling equipment is low, and the depth of drilling equipment does not meet the requirements. Technology companies, this situation is very unfavorable to the country's strategic position in the marine industry; foreign deep-sea drilling mostly uses professional drilling ships or drilling platforms, which are equipped with drilling towers, drilling rigs and other equipment, with complex structures and huge costs

Drilling ships and drilling platforms have obvious disadvantages: they are greatly affected by wind and waves, the construction is cumbersome and inflexible, it takes a long time to set up the drilling equipment, and once the drilling position is changed, it has to be rebuilt

However, most of the robots currently used for deep sea exploration lack reliability verification, and robots with better flexibility have disadvantages such as less drilling volume and insufficient drilling depth.

In addition, robots with large drilling depths often have large structures, and flexibility cannot be guaranteed
