Specific embodiment
Below in conjunction with attached drawing, the present invention is described in detail.
Embodiment: a kind of portable fiber-optic heats test device, and structure is as shown in Figs 1-4, including carrying case 12 with plus
13 two parts of hot rod have the common component such as battery, inverter, charger, temperature controller in carrying case 12, and have temperature
Instruction, voltage instruction screen and relevant cables interface, box house construction are not discussed in detail here.
Heating pole 13 includes shell, heat shield, the composition of thermally conductive sheet 9.The shell is divided into the top part and the bottom part point: upper housing 5 with
Lower case 1, the heat shield are also divided into the top part and the bottom part point: upper heat shield 4 and lower heat shield 2.The upper housing 5 and lower case
1 is connected by hinge 3, is not separated convenient for raising.Hinge 3 is mounted on upper housing 5 and lower case 1 by screw 11.
It is fastened after upper housing 5 and 1 closing lid of lower case with magic strap 6, it is tight but also easy to disassemble not only to have ensure that upper-lower casing closed.
Upper-lower casing, which closes, allows internal temperature probe 7, heating tape 8, optical fiber tightly in order to which the heat for generating heating tape 8 does not distribute not go out
The temperature of 10 threes reach balance and it is consistent.
The upper housing 5 and 1 shape of lower case, take round or rectangular or other shapes all can, this patent diagram use
Circle describes.The material of the shell light carbon fibre material for having intensity or other plastic materials, all play it is light, do not lead
Hot, nonconducting effect.
What the interior of shell up and down was close to is upper and lower heat shield, and the inside of the two gluing knot, lower heat shield 2 is to lead
Backing 9, thermally conductive sheet 9 and lower heat shield 2 use gluing knot.The inside of upper heat shield 4 is temperature probe 7 and heating tape 8, and the two is also used
Glue is bonded together with upper heat shield 4.
The adhesive glue must high-temperature plastic.
The material of the thermally conductive sheet 9 is the good conductor of heat, all may be used with copper sheet, aluminium flake.Adequately by the temperature of heating tape 8
Degree is transmitted to optical fiber 10 up.
The heat shield is the materials such as ceramic fibre, not only heat-insulated, but also high temperature resistant.
The heating space of the heating tape 8 is the smaller the better, just wraps up optical fiber 10, heating tape 8, temperature probe 7, will
Heat controls in space.Guarantee that optical fiber 10, heating tape 8, the temperature of 7 three of temperature probe are consistent.
The length of heating pole 13 uses 1~3 meter, and the test with specific reference to distribution type fiber-optic line-type heat detector is wanted
It asks.For the quantity of magic strap 6 and hinge 3 depending on the length of heating pole 13, principle is that spacing is certain, and 5 lower case 1 of upper housing is closed
Joint close is minimum after lid.
The lead of the temperature probe 7 and heating tape 8 can be powered on after accessing carrying case 12.
In the present invention, cavity includes circular arc-shaped bottom portion 14-1 and transition part 14-2, and the width of transition part 14-2 is greater than circular arc
The maximum width of shape bottom 14-1, so that bottom is substantially completely bonded with the lower part of thermally conductive sheet 9 after optical fiber 10 is placed in cavity,
Top be heated band 8 squeeze after, to the transition part 14-2 compressive deformation of two sides extend, and because heating tape 8 protrude from it is heat-insulated
The outer edge of piece 4 and the edge trend of transition part 14-2 are consistent.So optical fiber 10 is extruded rear and connects with the two sides of thermally conductive sheet 9
Omnibearing heating is realized in touching.
Be using the carry out detection method of the present apparatus: raising 5 lower case 1 of upper housing, will with 13 equal length of heating pole or
Longer optical fiber 10 is placed into the thermally conductive sheet 9 in lower case 1.Then upper housing 5 is closed, with a certain number of 6 systems of magic strap
Tightly, guarantee that internal heat does not distribute.After ensuring closing lid, temperature probe 7 is corresponding on carrying case 12 to the lead of heating tape 8
Socket docking.The operation of carrying case 12 is powered to heating tape 8, after the time of energization one end, when the temperature display on carrying case 12 is steady
After fixed, optical fiber 10, heating tape 8,7 three's temperature of temperature probe reach unanimously be exactly current optical fiber 10 temperature, after temperature stabilization
Can determine whether optical fiber cable sensing fire detector is qualified.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
A variety of modifications of embodiment will be readily apparent to those skilled in the art, it is as defined herein general
Principle can be realized in other embodiments without departing from the spirit or scope of the present invention, not be described in detail
The part presented with partial enlargement is the prior art, herein without repeating.Therefore, the present invention is not intended to be limited to herein
