Deep sea movable portable drilling machine

Abstract

The invention discloses a deep sea movable portable drilling machine. A whole structure of lightweight upper and lower frame connection is adopted, multiple underwater propulsion devices which are symmetrically mounted can achieve functions of deep sea moving and precise fixed-pint work, meanwhile, a diversified carrying platform and a good ship machine connector are provided, flexibility and workefficiency of deep sea work can be wholly improved, the drilling machine comprises an upper layer frame and a lower layer frame which are connected, the top of the upper layer frame is provided witha top frame used for fixed connection of an upper cable, multiple propellers are mounted on the upper layer frame through a propeller fixed plate, a hydraulic station providing whole equipment hydraulic power is mounted on the upper layer frame, according to the lower layer frame, a back plate is vertically fixed to the interior of the lower layer frame, the side portion of the back plate is provided with a sliding rail in sliding connection with a sliding block, the sliding block is connected to a telescopic rod of a propelling oil cylinder, a power head is fixed to the sliding block, a drillrod is mounted on the bottom end of the power head, and a drill bit is mounted on the bottom of the drill rod.

Description

technical field [0001] The invention relates to a movable and portable drilling machine for deep-sea rock core sampling, which belongs to the technical field of marine observation. Background technique [0002] At present, in the field of marine observation and research, deep-sea core sampling is carried out by means of impact, injection, and drilling. The more common equipment includes drilling rigs, cutting saws, and hydraulic hammers. Due to its high sampling efficiency, low cost and easy operation, drilling rigs are widely used in existing deep-sea operations at home and abroad. [0003] The existing commonly used core drilling rig has the following disadvantages: First, it does not have a movable function. Because it is a large and medium-sized heavy equipment, it is completely deployed and operated by relying on large ships, and it is impossible to achieve precise fixed-point operations. . The second is that it is bulky, heavy, and difficult to transport; in some spe...

Problems solved by technology

[0003] The existing commonly used core drilling rig has the following disadvantages: First, it does not have a movable function. Because it is a large and medium-sized heavy equipment, it is completely deployed and operated by relying on large ships, and it is impossible to achieve precise fixed-point operations.

The second is that it is bulky, heavy, and difficult to transport; in some special occasions where only a small amount of sampling is required at the depth of the seabed and more precise fixed-point drilling is required, the existing drilling rigs are difficult to operate and difficult to achieve. Long and easy to cause waste of material cost

The third is that the addressing efficiency is low; due to the complex terrain of the seabed, the drilling rig needs to sit on the bottom and stabilize itself when drilling and sampling, and the equipment must be perpendicular to the seabed to start drilling
