Abstract
The utility model discloses an insulated instrument part, comprising a required insulated instrument unit and an insulated sleeve. The utility model is characterized in that the insulated sleeve is composed of a casing, a buffer layer, a Dewar flask with wide mouth, an insulated cover, and a rack; the required insulated instrument unit is supported by the rack and is installed in the Dewar flask. The required insulated instrument unit is a probe which is composed of a sodium iodide crystal, a photomultiplier tube, and a preposition amplifier. The utility model is also the probe of the neutron logging instrument, etc. The utility model can make the instrument carry out the normal work under the condition of the high cold and high heat. The utility model has advantages of simple structure, low cost, easy manufacture, etc.
Description
The utility model relates to instrument and meter, specifically a kind of instrument component that is incubated.
Some unit of some instrument and meter, for example the HpGe of the probe of the Nal crystal probe of r radiation survey meter, neutron logging instrument, survey meter probe, the probe of gravimetry instrument and the motherboard and the electronic devices and components of microcomputer can only be worked under near the temperature room temperature or the room temperature.When too high or too low for temperature, what have can't operate as normal, the meeting that the has damage (for example Nal crystal) of breaking.
The purpose of this utility model is to provide a kind of instrument component that is incubated, promptly to above-mentioned instrument and meter because of the unit that can't work even damage too high or too low for temperature carries out insulation design, to overcome above-mentioned shortcoming.
Design proposal of the present utility model comprises the instrument unit and the muff of needs insulation, it is characterized in that said muff is made up of shell, buffer layer, wide-mouth Dewar flask, insulation cover and support, need the instrument unit of insulation to be installed in Dewar flask inside by stent support.
Because Dewar flask is the very good device of a kind of heat-insulating property, its heat transfer coefficient is about 1/8th of best thermal insulation material heat transfer coefficient, therefore can make the instrument unit that needs insulation can keep the working environment of uniform temperature for a long time, but make a whole set of instrument and meter operate as normal, and can prevent the ambient temperature acute variation and the breaking, damaging of the instrument and meter that causes probe (as sodium iodide crystal, HpGe probe).
When needing constant temperature work as some unit of instrument and meter, because the utility model volume is less, available storage battery, the battery of using is energy refrigeration or heating, to exempt whole operating room air-conditioning constant temperature, and can make originally can not workable place, up to the monitoring of 200 ℃ water and the neutron well logging in the oil drilling etc., all can adopt the instrument unit that is incubated that the utility model provides and operate as normal as the field survey in high and cold, high thermally district, nuclear power plant's secondary circuit.
That the utility model also has is simple in structure, cost is low, easy manufacturing, advantage such as applied widely, also can be used for sodium iodide crystal, high purity germanium detector etc. are visited bad device easily because of jump in temperature transportation.
The utility model has following accompanying drawing:
Fig. 1 the utility model structural representation
Fig. 2 support synoptic diagram
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation, and outermost is a shell 2, and it can adopt metal (for example stainless steel, steel, aluminium, aluminium alloy etc.) or plastic production, is the containment vessel of Dewar flask 4 and instrument unit 1.The buffer layer 3 that has one deck to make between shell 2 and the Dewar flask 4 by polyfoam, cotton or other damping heat-barrier material, vibrations and impulsive force that it can be subjected to shell 2 weaken, in order to avoid damage Dewar flask 4 and instrument unit 1, and certain insulation effect is arranged.Dewar flask 4 is generally double glazing and makes, and the centre vacuumizes, plating mercury, and insulation, heat-proof quality is fabulous.In order to lay the instrument unit, the utility model adopts the wide-mouth Dewar flask, and opening part is provided with insulation cover 5.Instrument unit 1 is supported by support 6, is installed in the Dewar flask 4.Support 6 adopts polyfoam or other flexible material, and its shape can be an annular, also can adopt the annular outside to add leg 7(referring to Fig. 2), be beneficial to install.Instrument unit 1 needed lead, for example power lead, signal wire etc. can be drawn from the hole on the insulation cover 5.
The said instrument unit 1 that needs to be incubated of the utility model can be the probe that comprises sodium iodide crystal (Nal), photomultiplier and prime amplifier of nuclear radiation measurement instrument (for example r measuring instrument), it can be the probe of the neutron logging instrument used in the petroleum prospecting, can be the probe of gravimetry instrument, also can be the motherboard or the one board microcomputer of microcomputer.
Adopt design proposal of the present utility model can make the place of some original cisco unity malfunction, as open-air, high and cold height is thermally distinguished and some high temperature detected object, as the radioactive monitoring of nuclear power station secondary circuit water r, all can carry out normal testing.For the instrument that needs constant temperature, adopt design proposal of the present utility model, in Dewar flask 4, add pyrogenicity (for example heating wire) or refrigeration source (for example semiconductor cooler), because the space of constant temperature is little, power consumption is little, might adopt the storage battery source that is used as power, and makes the instrument operate as normal.During power failure, but instrument also operate as normal for several days.
