Abstract
The utility model discloses a heat-preserving casing for a logging instrument. The main body of the heat-preserving casing is a cylinder, wherein a vacuum chamber is processed between the outer wall of the central part of the cylinder and the inner wall of the cylinder, the inner cavity of the cylinder is provided with two electronic circuit supporting racks in opposite directions, a heat absorbing body and a heat insulation body matched with the structure shapes of the supporting shafts of the supporting racks and the inner wall of the cylinder are respectively arranged in a direction deviating from an electronic circuit and in a manner clinging to the supporting racks, and a plug and a socket are respectively arranged at the other side surface of the heat insulation body and in a manner clinging to the heat insulation body so as to be in electric signal connection with an electronic circuit part that accepts hear preservation. The heat-preserving casing employs a vacuum heat insulation technique, isolates the electronic circuit from an external high temperature environment, has the heat absorbing body made by high-efficiency heat absorbing materials, and provides favorable conditions for isolating a high temperature environment for underground electronic circuit measurement and for guaranteeing that the instrument operates normally for a long time under the high temperature environment.
Description
Technical field
The utility model relates to the lagging casing of petroleum geology exploration with logging instrumentation.
Background technology
What the lagging casing of the at present domestic logging instrumentation that generally uses adopted is the thermos structure of liner type, with the electronic circuit part of logging instrumentation, just needs the part of insulation during work; Be placed in the inner bag of bearing shell and get final product; No longer take other measures, adopt such its heat insulation effect of insulation construction undesirable, and the inconvenience of dismounting maintenance circuit; Waste line-internal usage space, install difficult inside of accomplishing big volume heater elements such as power supply.
Summary of the invention
The purpose of the utility model is to the problem that exists in the background technology, and the lagging casing of the logging instrumentation of a kind of good heat-insulation effect, convenient disassembly is provided.
For realizing the foregoing invention purpose; The technical scheme that the utility model adopted is: the lagging casing of logging instrumentation; Its main body is a cylindrical tube, is processed with vacuum chamber between the outer wall at said cylindrical tube middle part and the inwall, in the inner chamber of cylindrical tube, also is provided with the opposite electronic circuit bracing frame of both direction; The shaft section of bracing frame is down " mountain " font, places the electronic circuit of logging instrumentation between two bracing frames; Deviating from the direction of electronic circuit, be close to bracing frame absorber and the insulator that back shaft and cylindrical tube interior wall construction shape with bracing frame match is set respectively, wherein absorber is the inner can that is full of the metal heat absorbent; Insulator is inner nonmetal box of filling asbestos or other heat-barrier materials; In the another side of insulator, be adjacent to insulator plug and socket is set respectively, plug, socket adopt 31 core connector normal structures, are connected with the electronic circuit part electric signal of insulation.
In order to strengthen heat insulation effect, the inside surface of sealed chamber is carried out polishing, reducing thermoradiation efficiency, and sealed chamber is carried out evacuation processes, to reduce the heat transferred that cross-ventilation was produced.
The utlity model has following beneficial effect: the lagging casing of logging instrumentation; Employing vacuum heat-insulation technology; Utilize vacuum chamber and insulator to constitute enclosure space, electronic circuit and external high temperature environment is isolated, and be furnished with the absorber that efficient heat-absorbing material is processed; For the underground survey electronic circuit cuts off hot environment, guarantee that instrument long-time operate as normal under hot environment provides advantage.The integrated design of insulation shell and bearing structure in addition, using and keep in repair with conventional tool housing from the dismounting of circuit does not almost have difference, and instrument power source part all can be placed on insulation construction inside with line related, makes things convenient for durable.
Description of drawings
Fig. 1 is the structural representation of the lagging casing of the utility model logging instrumentation.
Among the figure: 1-cylindrical tube, 2-sealed chamber, 3-electronic circuit bracing frame, 4-absorber, 5-insulator, 6-plug, 7-socket.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1: the lagging casing of logging instrumentation, its main body are cylindrical tube (1), are processed with sealed chamber (2) between the outer wall at said cylindrical tube (1) middle part and the inwall; Sealing chamber (2) has been used for reference the heat preservation principle of glass liner of thermos; In order to strengthen heat insulation effect, the inside surface of sealed chamber (2) is carried out polishing, to reduce thermoradiation efficiency; And sealed chamber is vacuumized processing, to reduce the thermal loss that cross-ventilation was produced.
In the inner chamber of cylindrical tube (1), also be provided with the opposite electronic circuit bracing frame (3) of both direction, the shaft section of bracing frame (3) is down " mountain " font, places the electronic circuit of logging instrumentation between two bracing frames (3); Deviating from the direction of electronic circuit, be close to bracing frame (3) absorber (4) and insulator (5) are set respectively; Wherein the inside of absorber (4) is enclosed cavity; Make by metal material; Inside cavity is full of the metal heat absorbent, in order to absorb the heat that the amount of residual heat will that gets into from the outside and electronic devices and components self send; The inside of insulator (5) is enclosed cavity, is made by nonmetallic materials, and inner asbestos or other heat-barrier materials of filling is to reduce the direct heat transferred of two end faces; On the direction that deviates from insulator (5), be adjacent to insulator (5) plug (6), socket (7) are set respectively, adopt 31 core connector normal structures, the electronic circuit part that can satisfy insulation like this is connected with the electric signal of Other Instruments.
During work; The electronic circuit of insulation be in electronic circuit bracing frame (3) between; No matter the heat of insulation shell outside is all to be difficult to be delivered to the electronic circuit part that needs insulation from the cylinder direction or from the end face direction, thereby guarantee that logging instrumentation can long-time stable work under normal environment.
Claims (2)
1. the lagging casing of a logging instrumentation; Its main body is a cylindrical tube; It is characterized in that: be processed with vacuum chamber between the outer wall at said cylindrical tube middle part and the inwall; In the inner chamber of cylindrical tube, also be provided with the opposite electronic circuit bracing frame of both direction, the shaft section of bracing frame is down " mountain " font, places the electronic circuit of logging instrumentation between two bracing frames; Deviating from the direction of electronic circuit, be close to bracing frame absorber and the insulator that back shaft and cylindrical tube interior wall construction shape with bracing frame match is set respectively, wherein absorber is the inner can that is full of the metal heat absorbent; Insulator is inner nonmetal box of filling asbestos or other heat-barrier materials; In the another side of insulator, be adjacent to insulator plug and socket is set respectively, plug, socket adopt 31 core connector normal structures, are connected with the electronic circuit part electric signal of insulation.
