Specific embodiment
In order to the technical characteristic to inventing, purpose and effect are more clearly understood from, now control description of the drawings is of the invention
Specific embodiment, in the various figures identical label represent identical part.
Herein, " schematic " expression " serving as example, example or explanation ", will should not be described herein as " showing
Any diagram of meaning property ", embodiment are construed to a kind of preferred or more advantageous technical scheme.
For making simplified form, in each figure, part related to the present invention is only schematically show, their not generations
Table its as product practical structures.In addition, so that simplified form is readily appreciated, there is in some figures identical structure or function
Part, only symbolically depict one of those, or only marked one of those.
Herein, " one " not only represents " only this ", it is also possible to represent the situation of " more than one ".
Fig. 1 is used for a kind of structural representation of exemplary embodiment of fisher that core plugging notifying mechanism of rope core drilling is described.As schemed
Show, the fisher of core plugging notifying mechanism of rope core drilling includes that 10, valve shaft of a valve shaft covers 20, recovery hook and an elastic component 40.
Wherein, valve shaft 10 has a valve end 12 and a salvaging end 14.Valve end 12 be provided with a runner 122 and four let out
Discharge hole 124, escape orifice 124 are communicated in runner 122.In embodiment shown in the figure, runner 122 prolongs along the axial direction of valve shaft 10
Stretch, and escape orifice 124 is along the circumferential array of valve shaft 10.Runner 122 can be by for pumping the mud of fisher, and mud can be from
Discharge in escape orifice 124.
Valve shaft set 20 is socketed on valve shaft 10.Valve shaft set 20 is provided with a blocking part 22.Valve shaft set 20 can be axially opposing along which
Move in valve shaft 10 so that the 24 salable escape orifice 124 of jacket wall of valve shaft set 20.
There is recovery hook one to be salvaged end 32 and a connection end 34.Salvage the lance that end 32 can be connected in core plugging notifying mechanism of rope core drilling
50, and salvage end 32 and can realize the clamping to spearhead 50 using existing any structure, and salvage the card at end and spearhead
Termination process will not be described here.Connection end 34 is provided with a limiting section 342, and during fisher is thrown in, limiting section 342 blocks
It is connected to valve shaft set 20 so that valve shaft set 20 cannot be moved axially with respect to valve shaft 10 along which.In embodiment shown in the figure,
The fisher of core plugging notifying mechanism of rope core drilling is additionally provided with a crowfoot frame 60, salvages end 14 and is connected to connection end 34 by crowfoot frame 60.
One end of elastic component 40 is resisted against valve end 12, and its other end is resisted against blocking part 22.Beating in core plugging notifying mechanism of rope core drilling
Drag in a kind of exemplary embodiment of device, elastic component is stage clip.
Fig. 2 to Fig. 4 is used for the motor process of the fisher that core plugging notifying mechanism of rope core drilling is described.As shown in Fig. 2 now at fisher
In throwing in the drilling motion of state, i.e. fisher along core plugging notifying mechanism of rope core drilling, and recovery hook 30 also do not contacted with spearhead.Recovery hook 30
Limiting section 342 be connected in valve shaft set 20 so that valve shaft set 20 cannot be moved axially with respect to valve shaft 10 along which.24 sealing-in of jacket wall
With escape orifice 124.Elastic component 40 is in compressive state.Now, mud is connected with runner 122, as mud cannot be from escape orifice
Release in 124 so that the pressure of pumping mud acts on valve shaft 10, and then drive fisher is in the drilling of core plugging notifying mechanism of rope core drilling
Motion, even if drilling and the angle very little of horizontal plane, still can promote fisher to move by the pump pressure of mud.
Fisher continues to move in the borehole, until the salvaging end 32 of recovery hook starts to contact with spearhead 50.Such as Fig. 3 institutes
Show, salvaging end 32 and starting to contact with spearhead 50, spearhead 50 is promoted salvages end 32 so that the release of limiting section 342 and valve shaft set 20
Clamping.The elastic restoring force of elastic component 40 causes valve shaft set 20 to move axially with respect to valve shaft 10 along which, and jacket wall 24 discharge right
The sealing-in of escape orifice 124.The mud passed through in runner 122 is released from escape orifice 124, acts on valve shaft 10 so as to release
Mud pumping pressure, fisher are conveyed in place.
As shown in figure 4, after salvaging end 32 completes the clamping with spearhead 50, jacket wall 24 still discharges the envelope to escape orifice 124
Connect.Be not in swabbing due to there is escape orifice during fisher is lifted.
It should be understood that, although this specification is described according to each embodiment, but not each embodiment only includes one
Individual independent technical scheme, this narrating mode of description is only that those skilled in the art will should say for clarity
Used as an entirety, the technical scheme in each embodiment can also be through appropriately combined, and forming those skilled in the art can be with for bright book
The other embodiment of understanding.
The a series of detailed description in detail of those listed above is only for illustrating for possible embodiments of the invention,
They are simultaneously not used to limit the scope of the invention, all equivalent embodiments that is made without departing from skill spirit of the present invention or change
More, such as combination, segmentation or the repetition of feature, should be included within the scope of the present invention.
