Abstract
The utility model relates to a drill rod used for ocean exploration and the drill rod used for ocean exploration comprises an external pipe and an internal pipe, wherein an internal thread is formed in the left side of the external pipe, the left side of the internal pipe is connected with a connecting pipe with an external thread, and the left side of the internal pipe is sleeved with a small six-claw snap ring which is connected with the external pipe. A big six-claw snap ring is embedded between the right side of the internal pipe and the connecting pipe, and a chamber in which liquids or solidliquid mixture can circulate is formed between the internal pipe and the external pipe. An internal thread is arranged on the left side of the external pipe, and the left side of the external pipe is connected with the internal pipe through the small six-claw snap ring. The right side of the external pipe is provided with a connecting pipe which is provided with an external thread, and the connecting pipe and the internal pipe are connected through the big six-claw snap ring. When the drill rod is on, a first drill rod is connected with an internal thread of a second drill rod through the external thread on the connecting rod; in exploration process, the external pipe can transport sea water to a geological stratification and the internal pipe can pump the mixture of sand and water in a reverse direction, achieving the aims of exploration and calculating the ore beds on survey and mapping spot. The drill rod used for ocean exploration is simple in structure, high in exploration efficiency, and convenient to assemble and disassemble.
Description
Technical field
The utility model relates to the instrument that bores dark use in a kind of seafari, especially a kind of drilling rod for seafari ore bed, conveying ore in sand form.
Background technology
Drilling rod is in boring bar tool, to connect drill bit, the rod member in order to transferring power.Traditional drilling rod is because only have individual layer tube wall, and along with going deep into of exploration layer, the auxiliary liquid that seawater extracts as ore in sand form is fewer and feweri, when serious, even can not take out ore in sand form sea water mixing thing, and this will certainly affect the progress of extraction and the investigation and prospecting of ore in sand form.And existing double-layer drill rod is to adopt multiple pairs of screw thread tube heads to connect mostly on market, the short distance inner tube that nested inside is multistage, complex structure, installing/dismounting operation is loaded down with trivial details, and it is slow that drilling rod is changed speed, greatly reduced exploration efficiency.
Summary of the invention
Technical problem to be solved in the utility model be for the above-mentioned state of the art, provide a kind of simple in structure, exploration efficiency is high, for the drilling rod of seafari.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of drilling rod for seafari, comprise outer tube and inner tube, it is characterized in that: the left end of described outer tube forms internal thread, the right-hand member of outer tube is connected with and is shaped with externally threaded adapter, at the left end of inner tube, be arranged with the little six pawl snap rings that are connected with outer tube, at the right-hand member of inner tube and between taking over, be nested with large six pawl snap rings, between inner tube and outer tube, form for liquid or the cavity of solidliquid mixture circulation.
As improvement, described little six pawl snap rings are nested between outer tube and inner tube, and inner tube is provided with the step in mating connection with the pawl head of little six pawl snap rings, are provided with for liquid or the space of solidliquid mixture circulation between the pawl head of little six pawl snap rings; The endoporus of taking over is provided with the endoporus step in mating connection with the pawl head of large six pawl snap rings, is provided with for liquid or the space of solidliquid mixture circulation between the pawl head of large six pawl snap rings.
Improve, described adapter is two nipple joints again, and the right-hand member of described outer tube is provided with the internal thread matching with two nipple joints, and the inner end of described adapter and outer tube are threaded connection fixing, and the outside wall surface of adapter and the outside wall surface of outer tube are and are smoothly connected.
Compared with prior art, the utility model has the advantage of: the left end of outer tube is provided with internal thread, the left end of outer tube is connected by little six pawl snap rings with inner tube; The right-hand member of outer tube is provided with externally threaded adapter, take between inner tube and be connected by large six pawl snap rings, like this when drilling rod is worked, the external screw thread that passes through to take over of first drilling rod is connected with the internal thread of second drilling rod, in exploration process middle external tube pipe, toward geological stratification, carry seawater, the ore in sand form that in inner tube pipe, extraction exploration is in the other direction arrived and the mixture of water, reach and explore and calculate the object of surveying and drawing out seam distribution.The utility model is simple in structure, exploration efficiency is high, and installing/dismounting is all very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the drilling rod for seafari of the present embodiment, comprise outer tube 1 and inner tube 2, the left end of outer tube 1 forms internal thread 11, the right-hand member of outer tube 1 is connected with the adapter 4 that is shaped with external screw thread 41, at the left end of inner tube 2, be arranged with the little six pawl snap rings 3 that are connected with outer tube 1, at the right-hand member of inner tube 2 and between taking over 4, be nested with large six pawl snap rings 5, between inner tube 2 and outer tube 1, form for liquid or cavity 6 that solidliquid mixture circulates; Little six pawl snap rings 3 are nested between outer tube 1 and inner tube 2, and inner tube 2 is provided with the step in mating connection with the pawl head of little six pawl snap rings 3, are provided with for liquid or the space of solidliquid mixture circulation between the pawl head of little six pawl snap rings 3; Take over 4 endoporus and be provided with the endoporus step in mating connection with the pawl head of large six pawl snap rings 5, between the pawl head of large six pawl snap rings 5, be provided with for liquid or the space of solidliquid mixture circulation.When drilling rod is worked, the external screw thread 41 of the adapter 4 of first drilling rod is connected with the internal thread 11 of second drilling rod, in exploration process, the pipe internal cavity 6 of the outer tube 1 of drilling rod is carried seawater toward geological stratification like this, the ore in sand form that in the pipe of inner tube 2, extraction exploration is in the other direction arrived and the mixture of water, ancillary equipment just can detect the ore in sand form extracting and the mixture of water, reaches the object of exploring and calculate Survey and Mapping Office's seam distribution.
Wherein, taking over 4 be two nipple joints, and the right-hand member of outer tube 1 is provided with the internal thread matching with two nipple joints, takes over 4 inner end and outer tube 1 and is threaded connection fixingly, and after adapter 4 is connected with outer tube 1, the outside wall surface of adapter 4 and the outside wall surface of outer tube 1 are and are smoothly connected.
