Abstract

The invention provides a seabed multi-head continuous sampling drilling machine, relates to the technical field of drilling equipment, and solves the technical problem that the sampling efficiency is low when a drilling machine works. The drilling machine comprises a drilling machine body, the drilling machine body is provided with two or more power drilling mechanisms, a drilling tool transporting mechanism and a drilling tool storage mechanism, each power drilling mechanism comprises a vertical shaft and a power head used for being connected with a drilling rod, and the vertical shafts are vertically arranged and rotatably arranged with the axes of the vertical shafts as the centers; the vertical shafts are in transmission connection with the power head and can drive the power head to rotate, and the power head can move up and down for feeding; and the drilling tool storage mechanism is used for storing drilling rods and core barrels, and the drilling tool transporting mechanism is used for grabbing the core barrels and the drilling rods and transporting the core barrels and the drilling rods between the drilling tool storage mechanism and the power drilling mechanism. Multi-point sampling can be achieved through single-time seabed operation, the sampling number of single-time operation is increased, and the operation efficiency is improved. The drilling machine is compact in structure and convenient to transport and lower the deck.

Description

Technical field [0001] The present invention relates to the technical field of drilling equipment, in particular, to a seabed multi-head continuous sampling rig. Background technique [0002] In the sea shell, there is an extremely rich mineral resource, including oil, natural gas hydrate, multi-metal tuberculosis, cobalt shell, etc., the development of seabed resources can effectively alleviate global resources, seabed sampling equipment is to carry out marine geology and environmental science Research, the technical equipment necessary for marine mineral resources exploration and subsea engineering geological surveys. Due to different sampling depth requirements, a variety of subsea sampling equipment have been developed. Among them, the bottom of the underwater drilling machine is a drilling device that is completely operated in the seabed. Compared with the shallow sampling equipment, the sample is deep, the sample adoption rate is high, the number, the automation, and the in...
