Four, design pressure balance portion
This electric directional coring apparatus has designed the pressure balance part, concrete scheme is as follows: owing to the increase with hole depth, the hole internal pressure increases, in order to ensure under water high pressure sealing maintainability of this electric directional coring apparatus, designed pressure equaliser, because the restriction of engine chamber inside dimension, therefore setting pressure balance set in holding nut, this pressure balance cover be opened in the drilling fluid and with the equilibrium liquid isolating seal of inside, be fixed on the balance nut, balance nut adopts with holding nut and is threaded, and additional encryption seal, when mounted the pressure balance cover is extruded portion of air, can reduce as much as possible because of engine chamber and fail to be full of fully the impact that machinery oil brings, partly solve sealing structure and the pressure balance problem of oriented coretaking device when the deep hole by designing this pressure balance, guaranteed the reliability of drill spindle rotatory sealing in the drilling process.
Five, design mark drilling control arrangement
This electric directional coring apparatus has designed the mark drilling control arrangement, concrete scheme is as follows: use screw to add upper spring as on-off controller, screw is not connected with conductive copper during original state, when micro drill contacts with hole bed rock core, micro drill, axle, motor moves on together, screw contacts with conductive copper, whole circuit communication, the work of motor-driven drill bit, when reaching predetermined hole depth, screw and conductive copper break away from again, whole circuit disconnects, thereby automatically cutting off power source after index aperture is finished is punched in the self-opening power supply revolution at the bottom of realizing the drill bit contact hole, realize mark boring beginning and the automatic control that stops, guarantee the continuation of the journey ability to work of directional coring apparatus in the hole.
This electric directional coring apparatus advantage:
1, provides rechargable power supplies for oneself, saved the trouble of dismounting cell.
2, the miniature diamond bit of development and design, the cutting power consumption when having reduced directional coring apparatus work.
3, design constant voltage guiding rotary drilling system, the impact when having avoided external environment condition on this device work has guaranteed that simultaneously reliable guiding creeps into the balance with reaction torque.
4, by the design pressure bascule, greatly reduced the impact of down-hole high pressure on the engine chamber sealing, improved the reliability of sealing.
5, design utilizes the mark drilling control arrangement, has realized the automatic control of electric machine operation state, compact conformation, simple and practical.
6, whole device is integrated on the holding nut, and globality is strong, is convenient to keep in repair dismounting.
