Two, the design machinery rotation creeps into part
This electric directional coring apparatus has designed machinery rotation and has crept into part, and concrete scheme is as follows: because drilling technique and stratum requirement, so developed miniature diamond bit, the power consumption when working to reduce directional coring apparatus.Selected the power set of micro machine+reducer according to the eccentric demand of punching, realized being connected of motor and drill bit, axle by the crosshead shoe shaft coupling, motor-driven shaft coupling and axle drive a drill bit rotation during work, realization rotary drilling.
Three, design constant voltage guiding is crept into part
This electric directional coring apparatus has designed the constant voltage guiding and has crept into part, concrete scheme is as follows: mounting spring above motor, by the pre-compression force of electrode tip holder adjustment to spring, realize the needed the pressure of the drill of drill bit drilling process, no matter how the weight of measurement-while-drilling system changes in the discharge hole down, can realize constant pressure mark boring.Simultaneously in order to guarantee to lead reliably rotary drilling, the lead that design can move up and down with motor, an end adopts with motor bottom and is threaded, and the other end inserts in the gathering sill of holding nut, increases flow-guiding structure simultaneously, realizes the constant voltage rotary drilling of leading.
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 this electric directional coring apparatus high pressure sealing maintainability under water, designed pressure equaliser, because the restriction of engine chamber inside dimension, so 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, the 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 influence that machinery oil brings, partly solve sealing structure and the pressure balance problem of orientational coring 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 boring control device
This electric directional coring apparatus has designed mark boring control device, 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, entire circuit is communicated with, the work of motor-driven drill bit, when reaching predetermined hole depth, screw and conductive copper break away from once more, entire 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 influence when having avoided external environment condition to 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 influence of down-hole high pressure to the engine chamber sealing, improved the reliability of sealing.
5, design utilizes mark boring control device, 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.
