Fig. 2 is the schematic diagram of the utility model the latter half structure.
Fig. 3 is the integrally-built schematic diagram of the utility model.
The specific embodiment
The embodiment providing below in conjunction with accompanying drawing further illustrates the utility model.
As shown in drawings, the impact type isotope releaser of the utility model, it consists of the first half and the latter half, in the first half, there is rope socket 1 to be fixed on above rope socket joint 2, the switch that is connected with below of rope socket joint is controlled cover 3, switch is controlled cover outside and is set with the first spring 6, the first spring top has alignment pin 5 to be fixed on switch control cover outside, switch is controlled cover outside respectively top urceolus 27 and bottom urceolus 7, with the longitudinal pressure cap 4 of keyway 28, is arranged on urceolus upper end, top, in the latter half, there is lock sleeve 10, the upper end of lock sleeve has multiple tracks to cut longitudinally seam 9, lock sleeve is fixed on the upper end of top connection 11 by screw thread, the lower end of top connection is connected with into water dosing mouth joint 13, on water inlet dosing mouth joint, there are inlet opening 15 and interior dosing mouth 16, the water inlet dosing mouth joint outside at interior dosing mouth position is set with dosing mouth and closes cover 17, dosing mouth is closed and has been put outer medicine feeding hole 18, inner side, position, inlet opening has the double-purpose valve 12 with intake tunnel 14 to be fixed on center driving control link 8, water inlet dosing mouth joint lower end is connected with isotope storehouse cylinder 19, cylinder bottom, isotope storehouse has a plurality of isotope release aperture 22, lower contact 23 tops and isotope storehouse cylinder link together, lower contact bottom and tester connector 26 link together, tapered valve 20 with sealing ring 21 is arranged at center driving control link bottom, center driving control link top is successively through isotope storehouse cylinder, water inlet dosing mouth joint, top connection, center driving control link upper end is positioned at lock sleeve, end, center driving control link upper end is jujube core shape, the position that center driving control link bottom is positioned at tester connector is set with return spring 24, the lower end of the center driving control link below return spring is provided with elastic force adjusting nut 25, the first half and the latter half link together by bottom urceolus and top connection, and the upper end of center driving control link is positioned at the centre bore 29 that switch is controlled cover lower end.
Before this device is used, first switch control cover being controlled to the first spring putting together with switch is pulled upwardly, when switch is controlled the positioning key put and is pulled to pressure cap top along keyway, rotate to an angle, alignment pin 5 is stuck on the upper surface of pressure cap nonbonding groove location.The first spring that now switch control puts is in compressive state.Due to stopping of positioning key, switch is controlled cover can be not descending because of the effect of the first spring.
Then, wedging ring is at the return spring of the center driving control link bottom of lower controller, make to be fixed with the upwards action of center driving control link of double-purpose valve and taper valve, when the head at center driving control link top exposes lock sleeve, revolution switch is controlled cover, it is descending along the keyway of pressure cap inner side that switch is controlled the positioning key overlapping, and makes lock sleeve enter switch and control in cover.Rotate dosing mouth and close cover 17, outer medicine feeding hole 18 is communicated with interior medicine feeding hole 16, isotope is joined in the cylinder of isotope storehouse by inside and outside medicine feeding hole.Rotate again dosing mouth and close cover, medicine feeding hole 16 in sealing, now isotope releaser enters and treats release conditions.
During use, this isotope releaser is connected to logger upper end by tester connector 26, rope socket 1 upper end connects steel wire for logging, is lowered to by well logging.When arriving release depth, the face winch brake tightly of stopping fast, realizes anxious stopping, and now the switch of the first half is controlled cover 3, rope socket joint 2 is slack with rope socket 1, and miscellaneous part and instrument together continue descending.When overcoming the elastic force of the first spring, lock sleeve is deviate from the centre bore that switch is controlled cover 3, and lock sleeve opens immediately, and lock sleeve, under return spring effect, drives center driving control link to move down.Meanwhile, the end, upper end of center driving control link jujube core shape, after the constraint that loses lock sleeve, drives double-purpose valve to synchronize and move down return with taper valve.Now, double-purpose valve no longer blocks inlet opening, the intake tunnel 14 of injected water in pit shaft on inlet opening, double-purpose valve, by the isotope in the cylinder of isotope storehouse after isotope release aperture is gone out, under the effect of the injected water of isotope in pit shaft, continue descendingly, with injected water, together enter after mined bed, the tester being connected under device can carry out intake profile test.
Top urceolus and bottom urceolus can be integral.
