Detailed description of the invention
The present invention includes claw 1, pull bar 2, basket body 3, lower adaptor 4, thrust bearing 5, pin 6, spring 7, pin
Nail 8, casing 9, leading screw 10, fixing swivel nut 11, sheath 12, planetary reduction gear 13, direct current generator 14, upper adaptor 15, its feature
Being that upper adaptor is threadeded with sheath, sheath is threadeded with lower adaptor, and lower adaptor leads to basket body inner circumferential
Crossing threaded, threadeds with casing top in basket body periphery, is provided with direct current generator, planet in sheath from the top down
Decelerator and fixing swivel nut；It is provided with four claw grooves of symmetry in the bottom week side of casing, is provided with in claw groove and connects with pin
Four claws, between claw top and casing, be provided with stage clip；In being provided with in fixing swivel nut, lower adaptor, salvaging main body
Central hole, is provided with leading screw and pull bar in centre bore, is provided with thrust bearing, leading screw and pull bar between fixing swivel nut and lower adaptor
Threaded, and fix with pin, pull bar stretches into the upper inside of pulling claw；Unidirectional current arbor is connected with input shaft of planetary reduction gear,
The output shaft of planetary reduction gear is connected with leading screw, and direct current generator is fixed on fixing swivel nut, constitutes electronic fisher.
When applying this utility model, head harness and lead fill steel wire cable and are connected, head harness again with electronic fisher
Upper adaptor 15 is connected, and equipped with supply socket on upper adaptor, lead dress steel wire cable is by supply socket and direct current generator 14
Being connected, direct current generator is connected with planetary reduction gear 13.Electronic fisher by lead dress steel wire cable from well head G.I.H,
Before lower salvaging thing, first starting direct current generator and rotate, the high speed rotating of direct current generator is slowed down as low speed by planetary reduction gear
Rotating, speed reducing ratio is: 941:1, reduces rotating speed, increases torsion, and planetary reduction gear output shaft is connected with leading screw 10 again, unidirectional current
Machine drives leading screw 10 forward and backward；Thrust bearing 5 acts primarily as and bears down-hole pressure and reduce leading screw mill resistance effect；Leading screw and pull bar 2
Swivel nut hole be connected, pull bar lower end is inserted again in claw, and claw is fixed on casing with pin again, the pin 8 in the middle part of pull bar
Be in the square opening of basket body 3, it is therefore prevented that pull bar rotate, under the turning effort of leading screw can only upstream or downstream, on
During row, under the effect of stage clip, claw closes up, and time descending, under the effect of pull bar, claw opens.The upper end fluid sealant of leading screw
Circle seals, it is ensured that down-hole liquid does not penetrate in sheath 12.When surface power supply, making direct current generator rotate, planetary reduction gear exports
Axle drives leading screw to rotate, and is moved up and down by the pull bar that rotarily drives of leading screw, and the inclined-plane on pull bar makes salvaging claw close up or opens
Open.When salvaging claw is typically first closed up by electronic fisher when going into the well, and claw pressured spring when opening backs down, when needs close up
Time need to drive with direct current generator, and promptly dragged for object；Lower to when being dragged for object about 10m, first by motor reversal, it is allowed to claw and opens
Opening, the circular area of claw head increases, and is conducive to once salvaging successfully.When continuing to transfer electronic fisher to salvaged object
Time, draw claw the most again in, salvaged thing can be caught, be viewed and emulated the change of direct current generator electric current by ground, just may know that
Whether salvaged thing is dragged for.
