Further push rod and the outer wall of ram seat 300 are divided equally other to be threadedly coupled with casing 200.So the present embodiment fills
The mode of operation set is to hold or be fixed casing 200, then rotating operating head 100 keeps push rod mobile to the bottom in country rock hole,
And then drive the operating side of variable diameter component 400 by push rod.
In some embodiments, push rod is threaded with intermediate bar 310, intermediate bar 310 and front axle in ram seat 300
The molding of 441 one.So push rod and casing 200 can quickly be dismantled from ram seat 300.
The variable diameter component 400 and variable diameter component 400 and the structural relation of the present apparatus that the present embodiment discloses show in Fig. 2 and Fig. 3
Out.The variable diameter component 400 of the present embodiment is installed between ram seat 300 and end seat 500.Variable diameter component 400 includes preceding change
Diameter pedestal 410, rear variable diameter pedestal 420, variable diameter bar 440 and four activity cones 430.
Fig. 1 and be cylinder with 300 equivalent diameter of ram seat Fig. 2 shows preceding variable diameter pedestal 410, and integrated be formed in
For ram seat 300 towards the end of country rock hole bottom, the middle part of preceding variable diameter pedestal 410 offers perforative preceding variable diameter along drilling direction
The inner wall of through-hole 411, preceding diameter bore 411 has internal screw thread.Variable diameter pedestal 420 is the cylinder with end 500 equivalent diameters of seat afterwards,
And the integrated end for being formed in end seat 500 and being open towards country rock hole.It is opened along drilling direction at the middle part of preceding variable diameter pedestal 410
Equipped with perforative rear variable diameter hole 421.
Four 430 bottoms of activity cone are limited in four limiting slots of rear 420 end surface of variable diameter pedestal.Four simultaneously
The limiting slot of activity cone 430 is uniformly looped around rear variable diameter hole 421, and limiting slot is one end towards rear variable diameter hole 421, another
The outside for being communicated to the present apparatus of end vertical drilling direction.It is all activity cone 430 towards rear variable diameter hole 421 end in direction
The side of preceding variable diameter pedestal 410 is configured to lozenges.General activity cone 430 is less than or equal in the sliding range of limiting slot
The depth in variable diameter hole 421 after described.
Fig. 3 shows the structure of the present embodiment variable diameter bar 440.Variable diameter bar 440 is shaped as along drilling direction is successively integrated
Front axle 441, axis 442 and rear axle 443.The inside of diameter bore 411 before front axle 441 is in, and there is outer spiral shell with outside
Line can with the screw-internal thread fit of preceding diameter bore 411, while front axle 441 towards the end of ram seat 300 as variable diameter component
400 operating side is coaxially fixed with push rod.Axis 442 when variable diameter component 400 is not driven in preceding diameter bore 411
Portion, and it is configured with the conical surface with the lozenges cooperation of each activity cone 430.Rear axle 443 along drilling direction extend into after become
Diameter hole 421.
The variable diameter component 400 that the present embodiment discloses is applied external force rotation in operating head 100 and casing 200 is fixed
When, 440 synchronous rotary of push rod and variable diameter bar, and elapsed along drilling direction to the bottom in country rock hole.The axis of variable diameter bar 440
442 make four activity cones 430 along limiting slot to the outside of the present apparatus during passage by the cooperation of lozenges and the conical surface, i.e.,
The side wall in country rock hole.After the activity cone 430 of the present embodiment is sufficiently abutted with the side wall in country rock hole, the present apparatus and country rock are opposite
Fixation, so that three-component acceleration detector can preferably receive the seismic signal of reflection.
Variable diameter component 400 is in the rotation of application external force that operating head 100 is reversed and when casing 200 is fixed, mantle with
The side wall in country rock hole, which contacts, to abut, then can directly take out the present apparatus from country rock hole.
As shown in figure 1, the present embodiment operating head 100, push rod, front axle 441, axis 442, rear axle 443 and end seat 500 are equal
Tiny wire guide that can be traditional for three-component acceleration detector is offered, the data for acquiring three-component acceleration detector
It can be communicated to outside the present apparatus.
In some embodiments, the whole material by non-signal shielding of all components of the present apparatus is made, as hard is moulded
Material etc..So three-component acceleration detector can be equipped with wireless communication module in internal or external, such as WI-FI or LORA
Transceiver module, the data that wireless communication module acquires three-component acceleration detector are by outside wireless communication to the present apparatus.
Preferred Fig. 4 is shown, and the end surface of rear variable diameter pedestal 420 towards preceding variable diameter pedestal 410 is variable diameter hole 421 backward
Concave station after inclined.Limiting slot is disposed in rear boss and no longer vertical drilling direction, but the one end of limiting slot is after
Boss is towards rear variable diameter hole 421, and the other end is along rear boss towards the outside of the present apparatus.Preceding variable diameter pedestal 410 is towards rear variable diameter
The end surface of pedestal 420 is the inclined preceding concave station in variable diameter hole 421 backward.Four such as sections in Fig. 4 of activity cone 430 are parallel
Quadrangle, parallelogram is along drilling direction towards the bottom angled in country rock hole.
So this preferred activity cone 430 can be inclined with respect to drilling direction by the conical surface of the axis 442 of variable diameter bar 440
The abutting with country rock hole side wall is realized in ejection, is able to use the present apparatus in the country rock hole of complex environment, is improved the reality of the present apparatus
Use performance.Meanwhile after the revocation of the conical surface of the axis of variable diameter bar 440 442 is to the ejection of activity cone 430, activity cone 430 can be
It is all extend between preceding variable diameter pedestal 410 and rear variable diameter pedestal 420 under the action of self gravity along limiting slot, the present apparatus is made to exist
Terminate that taking-up can be facilitated when using.
Preferred Fig. 5 is shown, and the rear axle 443 of variable diameter bar 440 is threadedly coupled with rear variable diameter hole 421.So rear axle 443 is with after
The threaded connection in variable diameter hole 421 makes preceding variable diameter pedestal 410, rear variable diameter pedestal 420, end seat 500, ram seat 300 and casing 200
Between remain and be relatively fixed, prevent the lozenges of activity cone 430 from, when abutting, making to cause to hold with the conical surface of axis 442
Headstock 500 and end 600 rotate in country rock hole, influence the use of the present apparatus, or cause to the destruction inside country rock hole.
In some embodiments, between the activity cone 430 of the present embodiment and preceding variable diameter pedestal 410 or rear variable diameter pedestal 420
Fixed returning spring enables activity cone 430 to extend into preceding variable diameter pedestal 410 and rear variable diameter pedestal under the action of returning spring
Between 420.
