Hose construction.Between the protective layer 41 of temperature-measuring optical fiber 5 and first, between the first protective layer 41 and the second protective layer 42 and second protection
Gap be present between the protective layer 43 of layer 42 and the 3rd.Protective case 4 can make temperature-measuring optical fiber bear pulling force and torsion when mounted,
And the ring-type of six or seven ten millimeters of diameter is easily bent into, the location division 11 of load bearing seat 1 is wound on without by stress, avoiding to light
Signal causes to be lost.The setting of 3rd protective layer 43 causes：First, temperature-measuring optical fiber 5 is in the 3rd protective layer 43 and load bearing seat all the time
Within 1 will not by external force, also will not because impaired and caused by light energy decay；Second, it can avoid revealing in installation
High-temperature electrolyte and bulk filter residue directly drop on temperature-measuring optical fiber 5 and damage optical fiber, when aluminium liquid falls in the 3rd protective layer 43
When outer, because aluminium liquid cooling is very fast, it can slide rapidly in the smooth outer wall of the 3rd protective layer 43.3rd protective layer 43 is not
Rust steel metal flexible pipe and load bearing seat 1 are connected by the first connector 3 or the second connector 30, and flange-connection stainless steel metal flexible pipe and first connects
The connector 30 of joint 3 or second rivets, and can not fall off in high temperature environments, during installation by the flange-connection stainless steel metal flexible pipe riveted and
First connector 3 is caught in first through hole 13, and the flange-connection stainless steel metal flexible pipe riveted and the second connector 30 are caught in into the second through hole
14 complete installation, finally penetrate the temperature-measuring optical fiber with the first protective layer 41 and the second protective layer 42 in the 3rd protective layer 43.
Gap is left between first protective layer 41 and temperature-measuring optical fiber 5, i.e. protective case 4 is set independently of each other with temperature-measuring optical fiber 5,
Gap between 3rd protective layer 43 and the second protective layer 42 is larger, when application external force pulls load bearing seat 1 or protective case 4, no
Temperature-measuring optical fiber 5 can be caused to damage, extend the service life of temperature-measuring optical fiber 5.
Reference picture 14-17, attachment structure include fixture 21 and adjusting part 22, and 21 C-shaped structure of fixture, it is included laterally
The top margin 211 of setting, the base 212 being be arranged in parallel with top margin 211 and vertically arranged side 213, the end bending of top margin 211

Pit 215 opens up close to the right part on base 212, is set so as to ensure that load bearing seat 1 is located just at the central lower of cathode steel bar 6
Put, ensure the Stability and veracity of monitoring temperature.Adjusting part 22 includes being connected to stretching on screwed hole 215 by external screw thread
Contracting part 221, into the active segment 223 of cylindricality, locating part 222 is set in the active segment for the top ring-type concave shape of extensible member 221
, can be up and down along active segment 223 on 223, the top of extensible member 221 has the back-up ring 224 for preventing that locating part 222 from deviating from, should
The external diameter of back-up ring 224 is less than or equal to the external diameter of extensible member 221.Anti-rotation gear causes when application external force rotary extension along 214 setting
During part 221, fixture 21 will not be rotated and then.
Locating part 222 is in the horn-like structure of opening up setting, and the side wall of locating part 222 can be linear structure
There can be arcuate structure, as long as its gradient or side wall length can guarantee that when locating part 222 is moved to the bottom of active segment 223
When, still have gap between the upper opening edge and the top surface of back-up ring 224 of locating part 222.
When the cathode steel bar 6 of temperature measuring equipment and electrolytic cell assembles, cathode steel bar 6 is coated on by fixture 21 from side movement
It is interior, top margin 211 is bonded with the top surface of cathode steel bar 6, extensible member 221 passes through from screwed hole 215 from bottom to top, will at the scene
The load bearing seat 1 for winding temperature-measuring optical fiber 5 is placed on the top of locating part 222, and the both ends of temperature-measuring optical fiber 5 are respectively from the first connector
3 and second pass in connector 30, apply external force and rotate extensible member 221, because locating part 222 is actively socketed on active segment 223,
Back-up ring 224 is not in contact with load bearing seat 1 simultaneously, so as to which load bearing seat 1 will not stretched with the synchronous axial system of extensible member 221, load bearing seat 1
Rise under the promotion of contracting part 221 and be in contact with the bottom surface of cathode steel bar 6, it is fixed because the surface of cathode steel bar 6 might have small convex closure
The top surface of position portion 11 can set the sunk structure of arc, ensure location division 11 and the contact surface of cathode steel bar 6.Now, load bearing seat 1
Closed space is formed between side and the bottom surface of cathode steel bar 6, the space is exactly mainly chamber 12, and the air conduction in space will
The temperature of cathode steel bar 6 is fast and efficiently conducted to temperature-measuring optical fiber 5.
Reference picture 18, a kind of distributed temperature measuring system for electrolytic cell cathode steel bar, it is arranged in electrolytic cell 7, is electrolysed
The both sides of groove 7 are evenly distributed with multiple cathode steel bars 6, and the end of each cathode steel bar, which is connected with, above-mentioned is used for electric tank cathode steel
The temperature measuring equipment of rod, the temperature measuring equipment between each cathode steel bar are connected by resistant to elevated temperatures temperature-measuring optical fiber, high temperature resistant temperature measuring optical
Fine one end is connected by common normal temperature temperature measuring optical cable with control module, and control module is connected with alarm module, control module
On can also be connected with display module and mobile phone terminal software.Can be with phase at D in the other end of high temperature resistant temperature-measuring optical fiber, i.e. Figure 18
Adjacent electrolytic cell is connected.The distributed temperature measuring system continuously can be monitored to the temperature of electrolytic cell cathode steel bar in real time,
Once its temperature triggers alarm module more than limit value and alarmed immediately, the service life of electrolytic cell can be not only improved, it is heavier
What is wanted is temperature field that can be by history monitoring and the big quantity stored to analyze and establish electrolytic cell, is later electrolytic cell
Design, improve and offer data foundation is provided.And mobile phone terminal realizes the function of remote supervisory and control(ling) equipment state, can also check
History curve and warning message.
Distributed temperature measuring system is placed in the Control Room of subregion, and control module uses multichannel thermometric main frame, Mei Getong
Road monitors two electrolytic cells, and a certain failure radiography is ringing other electrolytic cells just during avoiding more electrolytic cells of a channel monitoring
Often monitoring.Using the normal temperature temperature measuring optical cable of a multicore between plant area workshop and Control Room, to connect high temperature resistant on cathode steel bar
Temperature-measuring optical fiber and main frame, multicore normal temperature temperature measuring optical cable each two electrolytic cell are released a core and the welding of high temperature resistant temperature-measuring optical fiber and used up
Fine splice tray is protected, and two electrolytic cells are monitored as a passage, between two electrolytic cells that an optical channel monitors more
Connected with two fiber optic closures.So to ensure between passage to be all mutually insulated between two electrolytic cells of passage.
