Test specimens 101 by this pressure obliquely can produce with thermocouple 111 interact holding power obliquely, this two
Interaction force enables thermocouple 111 to be in close contact with tested sample 101, realizes clamping and firm function.Certainly, at this
The elastic clip 113 of other shapes and number in bright other embodiment, can be selected as needed, and elastic clip 113
Can change and do the holder that others are provided that identical function.
Specifically, signal processing apparatus are mainly the concrete data feeding back measurement temperature, in the other embodiment of the present invention
In, thermocouple 111 and signal processing apparatus also can be substituted with thermocouple thermometer.
Refering to Fig. 4, in the present embodiment, the second storage case 119 profile is similar to the cuboid not having bottom, the second receiving
Case 119 mainly includes：Roof 151, the 4th side wall 129, the 5th side wall 131.Second storage case 119 is detained with the first storage case 105
Close.Thermocouple 111 is placed in the second storage case 119.Second storage case 119 provides heat insulation function to thermocouple 111, ensures simultaneously
The safety of operation, it is to avoid scald.
Specifically, the face that the second storage case 119 is contacted with the first storage case 105 is provided with raised 141.Raised 141 are
Mutual with the size of the shrinkage pool 143 being respectively provided with the first side wall 115, second sidewall 121, the 3rd side wall 123, the 6th side wall 161
Cooperation.When monitoring device 100 is in heating test mode, raised 141 can stretch in shrinkage pool 143, to realize first with this
Storage case 105 and the stable fastening of the second storage case 119.
Specifically, the inwall of the first storage case 105 and the second storage case 119 is all wrapped in asbestos 149.Asbestos 149 are tools
The silicates mineral products have high-tensile, high flexible, chemically-resistant and thermal etching, being electrically insulated and there is spinnability.Therefore,
Inwall parcel asbestos 149 can thermal insulation.After parcel asbestos 149, when tested sample 101 is in heated condition, heat will not be excessive
Be delivered to beyond the first storage case 105 and the second storage case 119.This just avoid accordingly unexpectedly touch brought scald
Wound.Certainly, in other embodiments of the invention, asbestos 149 can also be changed to the thermal insulation barriers that other can play phase same-action, example
As evacuated panel, aerogel blanket etc..
Specifically, the roof 151 of the second storage case 119 is provided with opening 145 and the high temperature glass that opening 145 is closed
Glass 147, opening 145 can conveniently be tested and into passerby, experimentation be observed, in order to avoid unnecessary accident.High temp glass
147 is that glass can reach or bear corresponding temperature under the conditions of certain temperature, medium (acidproof, alkaline-resisting) and pressure rating
Degree, relevant pressure grade, the special glass of Applicable media, usually adopt high-purity siliceous mineral material, through high temperature refinement
Become, it still can hold the original permeability of glass and transparency in high temperature environments.High temp glass 147 has transparency
High, high temperature resistant, heat stability is good, stable chemical performance the features such as.Using high temp glass 147, opening 145 being carried out with closing is place
In security consideration, because the temperature of heating, the material of heating do not know, therefore in heating process it may happen that situation just not
Can determine that.In order to protect observer's personal safety, observer can understand and safe sight through transparent high temp glass 147
Observe the situation that experiment is carried out.
Specifically, the 4th side wall 129 of the second storage case 119 is provided with the 3rd groove 133, and the 5th side wall 131 is provided with
4th groove 135.3rd groove 133 and the 4th groove 135 have collectively constituted the second holding tank 155.Second holding tank 155 is arranged
Jointly coordinate clamping tested sample 101 in the first storage case 105 and the first holding tank 153.Due to the first holding tank 153 upwards
Active force and the second holding tank 155 apply downward active force make tested sample 101 carry out heating-up temperature monitoring when,
Can be clamped stable, do not rock.
The present embodiment additionally provides a kind of in-situ stretching device, including：Stretching device, heat radiation heating system 103, monitoring
Device 100.Stretching device can adopt existing commercial equipment, and the both sides of stretching device have two fixtures.When the original position providing is drawn
When stretching device and being in extended state, the two ends of tested sample 101 can be stretched the clamp at device two ends and make tested
The two ends of sample 101 are located remotely from each other.
In the present invention when needing the tested sample 101 of in-situ stretching device is carried out to heat extension test, can first group
Fill a small-sized monitoring device 100.First, heating assembly 107 is installed be located in the first storage case 105, that is, first
Thermal resistance and the support of fixing thermal resistance are installed in storage case 105.Tested sample 101 is placed in the second of the first storage case 105
In the first holding tank 153 that side wall 121 and the 3rd side wall 123 are formed.Then, the first receiving is stretched in elastic clip 113 one end
In the chute 117 of the first side wall 115 of case 105, the other end clamps thermocouple 111.The angle of regulation elasticity intermediate plate 113 and position
Put so that thermocouple 111 is contacted with tested sample 101 abutting, and will not occur mutually to rock.Second storage case 119 and first
Storage case 105 fastened so that the 4th side wall 129 of the second storage case 119 and the 5th side wall 131 formed second clamping
Groove 155 and the first holding tank 153 coincide, and thus to ensure that tested sample 101, during heating and thermometric, will not be shaken
Dynamic.After assembling finishes, the fixture of in-situ stretching device clamps the two ends of tested sample 101.And it is energized and thermal resistance is applied
Plus required voltage, thermal resistance heats to tested sample 101, after treating it stably, to thermocouple 111 and signal processing device
Put energising, after thermocouple 111 is contacted with tested sample 101, measured temperature signal is converted to the signal of telecommunication, at signal
Reason device is converted to the temperature of tested sample 101, and specific Temperature numerical is shown in the display screen of signal processing apparatus
On.When the required temperature that the temperature car following-theory recording carries out heating tension test has difference, the temperature for example recording is less than
Theoretical temperature required, then increase the voltage that thermal resistance is applied.The heating-up temperature making thermal resistance raises, and gives heat again
Galvanic couple 111 and signal processing apparatus energising, observe whether measured temperature is required temperature.If temperature is improper again
It is adjusted.Equally, when the position needing test temperature changes, can be sliding in chute 117 with regulation elasticity intermediate plate 113
Dynamic, to select accurate test position.Simultaneously as thermal resistance can not possibly make tested sample to the heating of tested sample 101
101 being heated evenly everywhere, so a dividing plate can be increased by the middle of thermal resistance and tested sample 101.Thermal resistance is carried out to dividing plate
Heating, dividing plate delivers heat to tested sample 101 again so that the thermally equivalent of tested sample 101.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
