Background technology
The downhole instrument limited space, compact conformation, work under bad environment, the routing problem of its through track is perplexing the structural engineer in this field always; In most of downhole instrument, the wiring of through track generally realizes by following four kinds of modes at present:
1. central tube uses the restriction of central tube cabling very large, can not the mounting center pipe in a lot of structures;
2. sealing-plug switching is used the sealing-plug cabling to be easy to cause Insulation Problems, and enough too much sealing-plugs of space mounting can not be provided in the instrument;
3. outside pressure-bearing hard tube because the shape of pressure-bearing pipe is irregular, is difficult to install, generally all be the pressure-bearing pipe disconnected be two sections or multistage, the centre installs adapter additional and realizes installing, adapter is wasting space relatively, hidden danger is also larger;
4. oil-filled high-pressure hose owing to need carefully to process oil circuit, realizes that difficulty is large, complicated structure.
Summary of the invention
The present invention is on the basis of externally pressure-bearing hard tube, proposes a kind of communication line routing device of subsurface equipment, the problem that is difficult to install to solve the pressure-bearing pipe.
Technical scheme of the present invention is: a kind of communication line routing device of subsurface equipment, the skeleton that contains logger, lower contact, the pressure-bearing pipe, the lower end of described skeleton connects lower contact, described pressure-bearing pipe two ends are communicated to respectively in the upper end of skeleton and in the lower contact, described pressure-bearing pipe is embedded in the groove of external surface of skeleton, described lower contact connects by the swivel nut that is sleeved between the two with skeleton, this swivel nut outside is provided with the internal thread coupling of screw thread and skeleton lower end, described swivel nut is by embedding the combined semi collar stop pushing tow lower contact of lower contact external surface, be provided with guide frame, the connecting portion of described pressure-bearing pipe and lower contact and described lower contact axially parallel with axially parallel between described lower contact and the skeleton lower end.
The two ends of described pressure-bearing pipe are respectively equipped with adapter, and this adapter inserts respectively in skeleton upper end and the lower contact, and insert in this adapter at the two ends of described pressure-bearing pipe.
Be respectively equipped with the sealing ring of coupling inside and outside the described adapter.
Described collar stop is set with snap ring.
Described collar stop has two groups, is block A and block B, and block A edge is provided with step and is absorbed in and contacts with swivel nut in the swivel nut, is set with snap ring on the described block B.
Described guiding mechanism comprises the gathering sill of the coupling that lays respectively at skeleton lower end inner surface and lower contact external surface and is installed in the interior gib block of this gathering sill.
The external diameter greater than described combined semi collar stop of the diameter of the externally threaded place circle of described swivel nut.
Beneficial effect of the present invention
Pressure-bearing pipe simple installation of the present invention, the centre does not have crossover sub, designs simplification, space hold is little, only does rectilinear motion during being connected of pressure-bearing pipe and lower contact and gets final product, and can finish the installation of pressure-bearing pipe when lower contact is installed.
The guiding mechanism of this invention has guaranteed the straight-line directionality in the lower contact installation process, and the cooperation of suit and collar stop by swivel nut has realized circular motion to straight-line conversion, thereby has realized the rectilinear motion to lower contact.
