Problems solved by technology

The seabed landforms are varied, including vast seabed plains, isolated towering seamounts, and even deep seabed caves. The above-mentioned vertical sampling technology relies on existing seabed drilling tools and is widely used in seabed plains and basins. In areas with special landforms such as seamounts and deep caves, sampling is difficult due to lack of suitable drilling tools

Abstract

The invention discloses an underwater robot portable horizontal-direction geological sampling drilling tool. The underwater robot portable horizontal-direction geological sampling drilling tool comprises a connecting base, a hydraulic motor, a transmission unit and a drilling and sampling unit; and the connecting base is provided with the hydraulic motor and the transmission unit, and the hydraulic motor is connected with the drilling and sampling unit through the transmission unit. The underwater robot portable horizontal-direction geological sampling drilling tool has the beneficial effectsthat seabed special landscape body geological sample taking operation is implemented, and the drilling tool has been applied to capturing in-situ samples of cavity walls of a certain sea area.

Description

technical field [0001] The invention belongs to the technical field of marine exploration, and relates to a drilling tool that can be operated by an ROV (underwater cable robot) to obtain in-situ geological samples in a horizontal direction on a seabed rock wall. Background technique [0002] With the gradual development of marine exploration technology to the deep sea, the use of ROV (Underwater Cable Robot) for submarine resource detection and marine scientific research has gradually become an important technical means. The acquisition of in situ geological samples is one of the important technical means for seabed scientific research. At present, the loose sediment sampling is mainly carried out by the managed gravity sampler, or the core sample collection is carried out by laying geological drilling holes on the offshore drilling platform. In the method of geological sampling based on ROV, it is mainly to carry PUSHCORE to carry out vertical loose sediment sampling and ...
