Embodiment 1

[0018] Such as figure 1 As shown, a small core sampling drilling rig operated by a manned submersible manipulator includes watertight cables 2 and 3, a handle 7, a drilling tool 8, a battery and a control cabin 1, a deep water transmission unit 6, a transmission flexible shaft 5 and Deep water power unit 4, etc.; battery and control cabin 1 are connected with deep water power unit 4 through watertight cables 2 and 3; deep water power unit 4 is connected with deep water transmission unit 6 through transmission flexible shaft 5; deep water transmission unit 6 and drilling tool 8 are connected through thread Connection; the entire drilling rig is installed in the sampling basket at the front of the deep submersible. The drilling tool 8 includes three parts: a drill bit, a coring sleeve and a core tube. The core sleeve adopts a barbed structure and is embedded in the core tube to prevent the core from falling off. Both ends of the core tube are processed with internal threads, and...

Embodiment 2

[0022] The drill bit is made of wear-resistant hard ceramics, the two ends of the core pipe are processed with external threads, the deep water motor 19 is welded on the shell 20 of the deep water power unit 4, and the others are the same as in the first embodiment.

Embodiment 3

[0024] The deep-water transmission unit 6 and the drilling tool 8 are connected by welding to ensure the reliability of the connection, and the others are the same as in the first embodiment.

Abstract

The invention belongs to the field of deep sea rock core sampling, and belongs to a small-size rock core sampling drilling machine based on manned deep submersible vehicle mechanical hand operation. The small-size rock core sampling drilling machine comprises a battery, a control cabin, a water-tight cable, a handle, a drill tool, a deep water transmission unit, a transmission soft shaft and a deep water power unit, wherein the battery and the control cabin are connected through the water-tight cable and the deep water power unit, the deep water power unit is connected with the transmission unit through the soft shaft, the transmission unit and the drill tool are connected through screw threads, and the whole drilling machine is arranged in a sampling basket arranged at the front end of a manned deep submersible vehicle. The small-size rock core sampling drilling machine is a special seabed crusting rock core drilling machine designed and manufactured for the manned deep submersible vehicle, the design and the manufacturing are in accordance with the principles of safety, reliability, advancing, economy and practicability, the small-size rock core sampling drilling machine can be arranged on a sampling basket support frame of the manned deep submersible vehicle, and the effective drilling core taking can be realized on the seabed crusting through adopting a mechanical hand operation mode. The small-size rock core sampling drilling machine is mainly used for sampling the seabed crusting rock cores, and has higher practicability.

Description

technical field [0001] The invention belongs to the field of deep-sea rock core sampling, in particular to a small-sized rock core sampling drilling rig operated by a manned deep submersible manipulator. Background technique [0002] The small core sampling drilling rig operated by the manipulator of the manned deep submersible is a necessary operating tool for the manned deep submersible to conduct seabed geological surveys and seabed mineral exploration. With the expansion of the application range of manned deep submersibles, the development of small deep-sea core sampling drilling rigs based on the manipulator of manned deep submersibles is very urgent. The Alvin of the Woods Hole Oceanographic Institution in the United States successfully obtained sulfide chimney samples in October 1991 with the HSTR corer. In 1995, the Harbor Branch Oceanographic Research Institute developed a coring device with a working sea depth of more than 7000m for the American Association of Oce...
