Embodiment 1

[0025] Such as Figure 1 to Figure 5 As shown, a portable hydraulically driven underwater drilling rig includes a base 1, a mast 2, a main lifting mechanism, an auxiliary lifting mechanism for lifting drill pipes and a main body of the drilling rig. The base 1 is a rectangular structure, and the four corners are provided with adjustable base level and screw rods for fixing the base. The mast 2 is vertically installed in the middle of the base 1. The left side of the base 1 is equipped with a winch 34, and the right side is provided with a passageway for drilling tools to pass through. Hole 40.

[0026] The main elevating mechanism comprises a rack 3, a support frame 4, a power output device 5, a driving gear 6, a transmission gear 7, a driven gear 8, two large guide wheels 9, two small guide wheels 10 and a locking device 11. The rack 3 is axially installed on the left side of the mast 2, and the left side of the support frame 4 is installed with a power output device 5, a dr...

Abstract

The invention discloses a portable hydraulic drive underwater drilling machine which comprises a base, a mast, a main lifting mechanism, an auxiliary drill pipe lifting mechanism and a drilling machine body, wherein the mast is vertically mounted on the base, the main lifting mechanism and the auxiliary drill pipe lifting mechanism are mounted on the mast, and the drilling machine body is mounted on the main lifting mechanism and comprises a hydraulic motor, a power head and a drilling tool. The power head is mounted on a bearing support, drives the drilling tool to rotate by the hydraulic motor and drives the drilling tool to vertically move by the main lifting mechanism. According to the portable hydraulic drive underwater drilling machine, underwater staff and machinery are stabilized by the aid of an underwater operation platform comprising the base, the main lifting mechanism and the auxiliary drill pipe lifting mechanism, cores can be easily sampled in the presence of flashy flow, the drilling machine can automatically advance downwards along the lifting mechanism under the action of dead weight, operation of the underwater staff is decreased, advance speed can be freely adjusted by the main lifting mechanism, and drilling efficiency is improved.

Description

technical field [0001] The invention relates to marine exploration mechanical equipment, in particular to a portable hydraulically driven underwater drilling rig for obtaining reef-building coral cores. Background technique [0002] Reef-building corals, also known as reef-building corals, are mainly distributed in warm, transparent, and oligotrophic tropical shallow waters. Reef-building corals are very sensitive to environmental changes. The isotopes and elemental compositions in their calcium skeletons can be used to reconstruct high-resolution seawater temperature, salinity, pH, rainfall and other information. Today's hottest global change, ocean acidification, and the most direct carrier of human activities' impact on climate and environment. Therefore, the acquisition of reef-building coral core samples plays a vital role in the research and development of marine science. [0003] At present, reef-building coral core samples are mainly obtained through pneumatic unde...
