Abstract

A kind of annular heat-absorbing sleeve for petroleum logging instruments, comprise the circuit framework of vacuum flask and vacuum flask inside, vacuum flask inside is provided with chuck, gap is left between vacuum flask and chuck, the port part of vacuum flask is provided with the seal cover with through hole, circuit framework is provided with in chuck, heat-absorbing sleeve is provided with outside circuit framework, heat-absorbing sleeve outside is provided with cooling tube, the cooling tube other end connects refrigerator, and refrigerator connects compressor, compressor connection control device, controller is provided with switch and screen, and controller connects the temperature pick up being positioned at vacuum flask by wire.Should have circuit framework when working long hours, starting switch, temperature pick up gathers temperature signal in vacuum flask, and is sent to controller conversion, identification, process, if the too high timely startup compressor of temperature in vacuum flask, compressor drives refrigerator to freeze, and by cooling tube, circuit framework is lowered the temperature, ensure that circuit framework normally works, and cooling-down effect is obvious, safe and reliable, be easy to large-scale promotion application.

Description

Annular heat-absorbing sleeve for petroleum logging instruments
technical field:
The utility model relates to oil logging tool accessory technical field, refers in particular to a kind of annular heat-absorbing sleeve for petroleum logging instruments.
background technology:
The not resistance to high temperature of many circuit components in oil well logging instrument, but the temperature of down-hole reaches more than 175 DEG C sometimes, this just causes these circuit components cisco unity malfunctions, even breaks down.In order to protection circuit components and parts, way in the past installs heat absorbent respectively up and down at circuit framework, connects a collet more simultaneously, finally this four part be stored in a thermos bottle, slow down the rising of temperature with this at the upper heat absorbent other end.In oil well logging instrument, major part is all adopt this structure, but acquired effect is not very good, because circuit framework is completely exposed being stored in a thermos bottle substantially, such structure cooling-down effect is also not obvious, and can not ensure that circuit framework normally works by continued down.
utility model content:
The purpose of this utility model is to overcome the deficiency existed in above-mentioned technology, provides a kind of annular heat-absorbing sleeve for petroleum logging instruments.By cooling tube, circuit framework is lowered the temperature, thus avoid Yin Wendu too high and the phenomenon generation of the normal work of impact.
The purpose of this utility model realizes as follows: a kind of annular heat-absorbing sleeve for petroleum logging instruments, comprise the circuit framework of vacuum flask and vacuum flask inside, described vacuum flask inside is provided with chuck, gap is left between described vacuum flask and chuck, the port part of described vacuum flask is provided with the seal cover with through hole, circuit framework is provided with in described chuck, heat-absorbing sleeve is provided with outside described circuit framework, described heat-absorbing sleeve outside is provided with cooling tube, the described cooling tube other end connects refrigerator, described refrigerator connects compressor, described compressor connection control device, described controller is provided with switch and screen, described controller connects the temperature pick up being positioned at vacuum flask by wire.
Described cooling tube is spirally wound on heat-absorbing sleeve.
Described through-hole diameter is less than chuck diameter.
Gap between described vacuum flask and chuck is built with asbestos.
The beneficial effects of the utility model are: reasonable in design, and be skillfully constructed novelty, and the asbestos in the gap between chuck and vacuum flask can play heat insulation effect, prevent vacuum flask external high temperature and affect the normal work of vacuum flask internal circuit skeleton; Heat-absorbing sleeve and cooling tube have good cooling-down effect to circuit framework, safe and reliable, are easy to large-scale promotion application.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
detailed description of the invention:
With reference to Fig. 1, a kind of annular heat-absorbing sleeve for petroleum logging instruments, comprise the circuit framework 5 of vacuum flask 1 and vacuum flask 1 inside, described vacuum flask 1 inside is provided with chuck 2, gap is left between described vacuum flask 1 and chuck 2, the port part of described vacuum flask 1 is provided with the seal cover 6 with through hole 11, circuit framework 5 is provided with in described chuck 2, heat-absorbing sleeve 4 is provided with outside described circuit framework 5, described heat-absorbing sleeve 4 outside is provided with cooling tube 3, described cooling tube 3 other end connects refrigerator 7, described refrigerator 7 connects compressor 8, described compressor 8 connection control device 10, described controller 10 is provided with switch 9 and screen, described controller 10 connects the temperature pick up 12 being positioned at vacuum flask 1 by wire.Described cooling tube 3 is spirally wound on heat-absorbing sleeve 4.Described through hole 11 diameter is less than chuck 2 diameter.Gap between described vacuum flask 1 and chuck 2 is built with asbestos.
When circuit framework 5 works long hours, first absorbed heat by heat-absorbing sleeve 4, starting switch 9 after a period of time, temperature pick up 12 gathers temperature signal in vacuum flask 1, and be sent to controller 10 and change, identify, process, if the too high timely startup compressor 8 of temperature in vacuum flask 1, compressor 8 drives refrigerator 7 to freeze, and lowered the temperature by cooling tube 3 pairs of circuit frameworks 5, ensure that circuit framework 5 normally works.
The utility model reasonable in design, be skillfully constructed novelty, and the asbestos in the gap between chuck 2 and vacuum flask 1 can play heat insulation effect, prevents vacuum flask 1 external high temperature and affect the normal work of vacuum flask 1 internal circuit skeleton 5; Heat-absorbing sleeve 4 and cooling tube 3 pairs of circuit frameworks 5 have good cooling-down effect, safe and reliable, are easy to large-scale promotion application.
