Upper adapter upper and lower is provided with male thread, and top is provided with electrical socket, and bottom is provided with wears cable aperture.
Fixedly swivel nut is made as cylindrically, and upper end diameter is greater than lower diameter, in upper surface, is provided with fixed screw holes.
Lower adapter is made as cylindrical, and middle part diameter is greater than upper and lower diameter, and upper periphery is provided with male thread, is provided with box thread thread segment middle part interior week and is provided with pin hole, and bottom is provided with male thread, and periphery and interior week are provided with seal groove.
Basket body is made as cylindrical, and lower, transverse is provided with a square opening, and top is provided with male thread.
Casing is made as cylindrical, and lower end is provided with a horn mouth, and top is provided with male thread.
Pull bar is made as cylindrical, and lower end is provided with the taper of hole enlargement at upper conical head, and top is provided with swivel nut hole, and middle part is provided with the pin that prevents pull bar rotation.
Electronic fisher has following feature:
1, the diameter of going into the well is little, and during salvaging, variable large salvaging area, has very high success rate.
2,, by the variation of supply current, can judge whether to salvage successfully.
If 3 while salvaging salvaged object, meet card when serious, can discharge salvaged thing by motor reversal, avoid causing cable to be pulled off accident.
4, direct-reading is considerable, has improved operating efficiency, minimizing accident.
5, simple to operation.
Accompanying drawing explanation
Accompanying drawing-structural representation of the present invention.
The fixing upper adapter of swivel nut 12-sheath 13-planetary reduction gear 14-direct current generator 15-of adapter 5-thrust bearing 6-pin 7-spring 8-pin 9-casing 10-leading screw 11-under 1-claw 2-pull bar 3-basket body 4-in figure.
The specific embodiment
The present invention includes claw 1, pull bar 2, basket body 3, lower adapter 4, thrust bearing 5, pin 6, spring 7, pin 8, casing 9, leading screw 10, fixedly swivel nut 11, sheath 12, planetary reduction gear 13, direct current generator 14, upper adapter 15, it is characterized in that adapter is threaded with sheath, sheath is threaded with lower adapter, lower adapter is threaded with in basket body in week, basket body periphery is threaded with casing top, is provided with from the top down direct current generator, planetary reduction gear and fixing swivel nut in sheath; In the bottom of casing, week side is provided with four symmetrical claw grooves, is provided with four claws that connect with pin in claw groove, between claw top and casing, is provided with stage clip; Fixing swivel nut, under carry down joint, salvage in main body and be provided with centre bore, in centre bore, be provided with leading screw and pull bar, fixedly between swivel nut and lower adapter, be provided with thrust bearing, leading screw is connected with pull rod screw, and with pin, fix, pull bar stretches into the upper inside of pulling claw; Direct current arbor is connected with input shaft of planetary reduction gear, and the output shaft of planetary reduction gear is connected with leading screw, and direct current generator is fixed on fixedly on swivel nut, forms electronic fisher.
When application is of the present invention, head harness is connected with plumbous dress steel wire cable, and head harness is connected with the upper adapter 15 of electronic fisher again, on upper adapter, electrical socket is housed, plumbous dress steel wire cable is connected with direct current generator 14 by electrical socket, and direct current generator is connected with planetary reduction gear 13.Electronic fisher fills steel wire cable from well head G.I.H by lead, before lower salvaging thing, first start direct current generator rotation, planetary reduction gear slows down the High Rotation Speed of direct current generator for low speed rotation, speed reducing ratio is: 941:1, reduce rotating speed, and increase torsion, planetary reduction gear output shaft is connected with leading screw 10 again, and direct current generator drives leading screw 10 forward and backwards; Thrust bearing 5 mainly works down-hole pressure and the minimizing leading screw mill resistance effect of bearing; Leading screw is connected with the swivel nut hole of pull bar 2, pull bar lower end is inserted again in claw, claw is fixed on casing with pin again, the pin 8 at pull bar middle part is in the square opening of basket body 3, has prevented pull bar rotation, can only upstream or downstream under the turning effort of leading screw, when up, under the effect of stage clip, claw closes up, and when descending, under the effect of pull bar, claw opens.The upper end of leading screw seals with O-ring seal, guarantees that down-hole liquid does not infiltrate in sheath 12.When surface power supply, direct current generator is rotated, planetary reduction gear output shaft drives leading screw rotation, and the pull bar that rotarily drives by leading screw moves up and down, and the inclined-plane on pull bar makes to salvage claw and closes up or open.When electronic fisher generally first closes up salvaging claw when going into the well, claw pressured spring when opening backs down, and need drive with direct current generator, and promptly dragged for object when needs close up; While being dragged for the about 10m of object to quilt down, first by motor reversal, making it claw opens, and the circular area of claw head increases, and is conducive to once salvage successfully.When continuing to transfer electronic fisher to salvaged object, at this moment draw again claw in, salvaged thing can be caught, by ground, view and emulate the variation of direct current generator electric current, just can know whether salvaged thing is dragged for.
