Technical Field

The invention discloses a movable portable drilling machine for deep sea core sampling, and belongs to the technical field of ocean observation.

Background

At present, in the field of ocean observation and research, deep sea core sampling is performed by using modes such as impacting, injecting and drilling, and common equipment comprises a drilling machine, a cutting saw, a hydraulic hammer and the like. The drilling machine is widely applied to the existing deep sea operation at home and abroad based on the characteristics of higher sampling efficiency, lower manufacturing cost, easy operation and the like.

The existing commonly used core drilling machines have the following disadvantages: firstly, the movable function is not provided, and the movable equipment is a large and medium-sized reloading equipment, is completely dependent on large-scale ship feeding and laying and operation, and cannot realize accurate fixed-point operation. Secondly, the device is large in size, heavy and difficult to transport; in some specific occasions, which only need a small amount of sampling, and need precise fixed-point drilling, the existing drilling machine is difficult to operate and realize operation, and material cost waste is easily caused due to overlong sampling depth. Thirdly, the addressing efficiency is low; because the submarine topography is more complicated, the drilling machine needs to sit on the bottom and stably when drilling and sampling, and the drilling can be started only when the equipment is vertical to the seabed. Because the equipment is heavy, if the equipment is found to be a slope and have an overlarge angle after sitting on the ground, the equipment can only be retracted again, is separated from the ground by a certain distance and then is dragged by moving the ship, and the equipment needs to be addressed again until a proper position is searched.

In view of this, the present patent application is specifically proposed.

Disclosure of Invention

The invention relates to a portable deep-sea drilling machine which is characterized in that an integral structure with a light upper frame and a light lower frame connected is adopted to solve the problems in the prior art, functions of deep-sea movement and accurate fixed-point operation are realized through a plurality of symmetrically-installed underwater propelling devices, a diversified carrying platform and a good ship-machine interface are provided, and the flexibility and the operation efficiency of deep-sea operation are integrally improved.

the upper layer frame and the lower layer frame are in butt joint installation through respective flange plates; and the upper-layer frame is provided with a transformer, a pushing control bin and a rectifying bin, and the compensator is connected with the hydraulic station through an oil pipe.

Through the connection of the flange plates, the upper frame and the lower frame can be conveniently disassembled, and the characteristics of convenient transportation, simplified function and simple operation are realized.

In order to optimize the structural design, control the cost and prevent the blockage problem in the drilling process, a valve box, a control bin and a flushing device are arranged in the lower-layer frame, and the flushing device is respectively connected with a power head and a drill rod.

In order to improve the flexible control of the movement of the whole machine, a plurality of propellers are symmetrically arranged along the vertical central axis of the upper-layer frame.

To sum up, the portable rig in this application deep sea has following advantage and beneficial effect:

1. the carrying and connecting structure is optimized integrally, so that convenient disassembly and maintenance operation is realized, and the improvement of the seabed sampling operation efficiency is facilitated;

2. the movable function and the accurate fixed-point operation of the deep sea drilling operation are realized, and the carried propellers can move in all directions.

3. The addressing efficiency is higher, is applicable to the sampling operation of finding the proper operation position by sitting on the bottom for many times. Multiple optimized operating points can be realized within a certain range.
