The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model scheme is done further explanation.
The utility model tackles the axial of wireless drilling inclinometers deviational survey pipe nipple and radially the proposition of combined shock absorption method is following tactful:
As shown in Figure 2, axially on, adopt the bi-directional combination damping modes; An end of the original installation ordinary buffer device drum type snubber 11 that changes the outfit on deviational survey pipe nipple stage body 10 connects another damping part 12 at the end that quartz accelerometer 13 is installed, and this damping part can be common rubber bumper; Also can be the drum type snubber in the utility model; Can also be common rubber bar, can also be the damping stage clip, be the damping stage clip shown in the figure.
The footpath upwards; Whole employing flower type circles, or the damping modes of flower type circle and combination of O type circle and usefulness, promptly several places in a place or interval are provided with colored type circle 14 on deviational survey pipe nipple stage body 10; Flower type circle 14 next doors can be provided with 1～2 O type circle 15; When two O type circles, in the middle of flower type circle was positioned at, two O type circles laid respectively at the both sides of colored type circle.
Further, colored type circle 14 can be set also on the plug 16 at deviational survey pipe nipple stage body 10 two ends, or O type circle 15, or both combinations.
Above-mentioned drum type snubber 11, flower type circle 14, O type circle 15 all adopt elastic deformable materials such as rubber.
When instrument in the raw the time, drum type snubber 11, flower type circle 14 closely contact with resistance to compression tube 17 inwalls in deviational survey pipe nipple stage body 10 outsides, O type circle 15 and resistance to compression tube 17 inwalls reservation certain interval.
Following for the analysis of above damping effect of Combination:
1) when the deviational survey pipe nipple when axially receiving strong vibration or large impact, with having a bigger impact force action on pipe nipple, at this moment the drum type snubber will be compressed; It will have the trend that expands outwardly in diametric(al); But owing to receive the restriction of outside resistance to compression tube 17, just produced the pressure of resistance to compression tube, so just traditional one dimension damping has been converted into two-dimentional damping through the drum type damper snubber; Reduce greatly the drum type buffer shaft to compressive strain, more effectively absorb the strong vibration large impact.
2) because drum type damper axial compression amount is less, so screen resilience is correspondingly less, add the buffering of top damping part, elastic force can be offset the screen resilience of damper well, so avoided axial oscillation; In the pipe nipple motion process, also have in addition and radially spend the frictional force between type circle and resistance to compression tube to work; Even very strong impact force is arranged; Under the effect of this combined shock absorption, also can eliminate through of short duration vibration, avoided traditional one dimension damping because screen resilience is big; Cause snubber to tear or pipe nipple clashes into plug when resilience, make the phenomenon of the sensor damage on the pipe nipple.
3) radially adopted colored type circle, both guaranteed to contact with the firm of resistance to compression tube, be unlikely to make pipe nipple to become " inflator " again, the hole at flower type circle edge can discharge the air in the pipe nipple; When the deviational survey pipe nipple when radially being impacted or being vibrated, flower type circle at first works, the compression through flower type circle absorbs and can weaken radial vibration or impact; Very strong when radially vibration or impact, when the decrement of flower type circle is not enough to eliminate fully, at this moment O type circle will play a role.In drilling process, large impact generally all derives from axially, a little less than the impact very radially, radially has only vibration usually, and the combined shock absorption that this colored type circle adds O type circle can overcome fully.
What be worth explanation is; The foregoing description only is used to explain the utility model; Wherein the structure of each parts, connected mode etc. all can change to some extent; But every equivalents of on the basis of the utility model technical scheme, carrying out and improvement all should not got rid of outside the protection domain of the utility model.
