Abstract

The utility model relates to a natural gamma shockproof probe. At present, when the common probe works underground, a photoelectric tube and a crystal are easy to crack due to the complex condition and large instrument shake, so the development of logging work is seriously influenced. The existing high shockproof probe is made by expensive shockproof materials and is not favorable to wide-scale application on site. The natural gamma shockproof probe comprises a photoelectric tube, a crystal, a sheath and a pressure spring. The inner wall of the sheath is provided with a diameter-changing step, and the outer side of the photoelectric tube is provided with a plurality of buffer rings rounded out the buffer shell of the photoelectric tube. A high light-guide buffer cushion and a buffer circle rounded out the high light-guide buffer cushion are arranged between the photoelectric tube and the crystal, and a buffer part is clamped between the crystal and a lower plug. The inner wall of the sheath is provided with a plurality of circular grooves, the buffer rings are inlaid in the groove, and the buffer circle is clamped between the end part of the crystal near the photoelectric tube and the diameter-changing step. The damage rate of the probe in logging work is reduced, the logging efficiency is increased, and the maintenance cost of instruments is reduced.

Description

The shockproof probe of a kind of natural gamma
Technical field
The utility model relates to the shockproof probe of a kind of natural gamma.
Background technology
At present, general natural gamma logging device probe is when underground work, because the vibrations of hole condition complex instrument are very big, photoelectric tube and the cracked situation of crystal often take place, have a strong impact on carrying out of well logging work, existing high antidetonation natural gamma logging device is to adopt expensive anti-seismic material to make, be unfavorable for on-the-spot extensive use, general natural gamma logging device is popped one's head in when underground work because the vibrations of situation complex instrument are very big, photoelectric tube and the cracked situation of crystal often take place, have a strong impact on carrying out of well logging work, existing high antidetonation natural gamma logging device is to adopt expensive anti-seismic material to make, and is unfavorable for on-the-spot extensive use.
Summary of the invention
The utility model provides a kind of natural gamma logging device sonde configuration that can play high anti seismic efficiency for photoelectric tube and the breakable phenomenon of crystal that overcomes logging instrument probe inside when working.
The technical solution of the utility model: the shockproof probe of a kind of natural gamma, comprise that photoelectric tube, crystal, sheath, holddown spring constitute, the reducing step is arranged on the described jacket inner wall, the arranged outside of described photoelectric tube has the damping shell, described damping shell comprises a plurality of shock rings of the outer winding of photoelectric tube, the shock absorbing ring of the outer winding of the high photoconduction damping rubber cushion of the sheet that is provided with between photoelectric tube and the crystal and high photoconduction damping rubber cushion also is folded with the ring-type shock absorber part between described crystal and the lower end cap.
The inwall of described sheath is provided with a plurality of annular recess, and a plurality of shock rings are embedded in the annular recess.
Described shock absorbing ring is located in crystal near between the end and reducing step of photoelectric tube.
The beneficial effects of the utility model are: improved the shock resistance of probe, reduce the probability that probe damages in well logging work, improved the success rate of well logging, lowered the maintenance cost of instrument.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Above-mentioned drawing reference numeral explanation: 1-photoelectric tube, 2-crystal, 3-protection pad, 4-holddown spring, the high photoconduction damping of 5-rubber cushion, 6-shock ring, 7-reducing step, 8-shock absorbing ring, 9-shock absorber part, 10-lower end cap, 11-upper plug head.
The specific embodiment
Referring to Fig. 1:
Upper plug head 11, holddown spring 4, shock ring 6, shock ring 7, photoelectric tube 1, beam 8, high photoconduction damping rubber cushion 5, crystal 2, shock absorber part 9, lower end cap 10 are inferior successively to be assemblied in the sheath 3, on described sheath 3 inwalls reducing step 7 is arranged, the arranged outside of photoelectric tube 1 has by a plurality of shock ring 6 outer damping shells around photoelectric tube 1, the high photoconduction damping rubber cushion 5 of the sheet that is provided with between photoelectric tube 1 and the crystal 2 and the shock absorbing ring 8 of high photoconduction damping rubber cushion 5 outer windings, shock absorber part 9 is arranged between crystal 2 and the lower end cap 10; The inwall of sheath 3 is provided with a plurality of annular recess, and a plurality of shock rings 6 are embedded in groove, and shock absorbing ring 8 is located in crystal 2 near between the end and reducing step 7 of photoelectric tube 1.
The utility model probe is when underground work; as run into vibrations; then photoelectric tube 1 and crystal 2 will shake; at this moment the shock absorber part 9 between the damping shell in the outside of photoelectric tube 1 and crystal 2 and the lower end cap 10 will play a protective effect to photoelectric tube 1 and crystal 2; make it can not break, reached the purpose of this utility model.
