Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermocouple technology, specifically a high-performance multi-point temperature measuring armored thermocouple. Background Technology
[0002] A thermocouple is a circuit composed of two different metal conductors. When the temperatures of the two junctions are different, a thermoelectric potential is generated, also known as the Seebeck effect, to measure the temperature inside a container. Multi-point thermocouples measure the temperature at different locations inside a container by increasing the number of conductors. Armored thermocouples usually refer to those with an outer metal sheath and an inner filling of insulating material, such as magnesium oxide. This structure is more robust and less prone to damage to the thermocouple wires.
[0003] Multi-point temperature measuring armored thermocouples contain multiple thermocouple wires. During use, if a thermocouple wire is damaged due to electrical faults, quality problems, or other reasons, it can either continue to be used, causing that point to be unable to measure temperature normally, thus affecting the performance of the armored thermocouple, or it can be replaced entirely. However, replacing the entire thermocouple will cause other good thermocouple wires to be replaced as well, resulting in waste of resources and increased costs. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a high-performance multi-point temperature measurement armored thermocouple to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance multi-point temperature-measuring armored thermocouple, comprising a junction box, wherein a first outer ring color label and a first inner ring color label are respectively provided on the upper surface of the outer surface of the junction box, a second outer ring color label and a second inner ring color label are respectively provided on the lower surface of the outer surface of the junction box, a cable tray is provided through the bottom of the junction box, a terminal block is installed inside the junction box, and a clamping screw is provided through the upper sides of both sides of the junction box.
[0006] By adopting the above technical solution, when a thermocouple wire is damaged, the worker first removes the bolts and then takes the junction box out of the container. At this time, the worker finds the damaged thermocouple wire, then finds the second outer ring color label or the second inner ring color label corresponding to the damaged thermocouple wire. The worker then loosens the clamping screws corresponding to the first outer ring color label and the first inner ring color label. At this time, the worker can remove the damaged armor sleeve, insulating thermal conductive layer and thermocouple wire. The worker then inserts the new armor sleeve, insulating thermal conductive layer and thermocouple wire into the hole of the cable tray. The cable tray is designed to facilitate the neat arrangement of thermocouple wires and avoid the thermocouple wires from getting tangled in the junction box, which would affect disassembly and assembly. After insertion, the worker finds the second outer ring color label or the second inner ring color label corresponding to the new thermocouple wire, and then tightens the clamping screws corresponding to the first outer ring color label and the first inner ring color label, so that the thermocouple wire is pressed in the junction tray to connect the current.
[0007] Furthermore, the first outer ring color label is located below the first inner ring color label, and the second outer ring color label is located above the second inner ring color label.
[0008] By adopting the above technical solution, when disassembling and assembling the armored sleeve and thermocouple wire, the second outer ring color label or the second inner ring color label corresponding to the hole at the bottom of the cable holder is located. Then, by operating the clamping screws corresponding to the first outer ring color label and the first inner ring color label, the disassembly and assembly of a certain armored sleeve and thermocouple wire can be completed. This makes it easy to find the position of the corresponding clamping screw, thereby facilitating disassembly and assembly and avoiding the operation of other clamping screws that may affect the disassembly and assembly.
[0009] Furthermore, the cable connector is stepped.
[0010] By adopting the above technical solution, the stepped shape of the cable tray makes it easier to find the first inner ring color label or the second inner ring color label corresponding to the thermocouple wire, thus facilitating operation.
[0011] Furthermore, the terminal block is made of copper.
[0012] By adopting the above technical solution, the thermocouple wire is pressed into the terminal block to connect the current. After the current is connected, the temperature of the material in the container can be measured through the thermocouple wire.
[0013] Furthermore, flange plates are connected to both sides of the junction box, and a thermocouple wire runs through the bottom of the cable tray, with an armored sleeve connected to the outer surface of the thermocouple wire through an insulating and heat-conducting layer.
[0014] By adopting the above technical solution, the workers pass the junction box through the top window of the container, and then use bolts and flange plates to limit the junction box to the container. At this time, multiple armored sleeves, thermocouple wires, and insulating thermally conductive layers are submerged in the material inside the container. Due to the large number of thermocouple wires, multi-point temperature measurement of the material inside the container can be achieved. During this process, the armored sleeves protect the thermocouple wires from being crushed or corroded. The insulating thermally conductive layer fills the gaps between the thermocouple wires and the armored sleeves, which serves two purposes: first, it provides insulation to prevent the current on the thermocouple wires from being conducted to the armored sleeves and causing short circuits; second, it provides thermal conductivity by filling the gaps, which accelerates heat conduction and facilitates the thermocouple wires in measuring the temperature of the material.
[0015] Furthermore, the armored sleeve is made of stainless steel, and the insulating and heat-conducting layer is made of magnesium oxide powder.
[0016] By adopting the above technical solution, the thermocouple wire is protected by the armored sleeve to prevent it from being crushed or corroded. The gap between the thermocouple wire and the armored sleeve is filled by the insulating and thermally conductive layer. This serves two purposes: first, it provides insulation, preventing the current on the thermocouple wire from being conducted to the armored sleeve and causing short circuits; second, it provides thermal conductivity, accelerating heat conduction by filling the gap, thus facilitating the thermocouple wire to measure the temperature of the material.
[0017] Furthermore, the thermocouple wire is detachably connected to the terminal block, and the clamping screw abuts against the thermocouple wire.
[0018] By adopting the above technical solution, the staff tightens the corresponding clamping screws, so that the thermocouple wire is pressed into the terminal block to connect the current.
[0019] Furthermore, multiple armored sleeves, thermocouple wires, insulating and heat-conducting layers, first outer ring color labels, second outer ring color labels, first inner ring color labels, second inner ring color labels, terminal blocks, and clamping screws are provided, and multiple armored sleeves, thermocouple wires, insulating and heat-conducting layers, first outer ring color labels, second outer ring color labels, first inner ring color labels, second inner ring color labels, terminal blocks, and clamping screws are arranged in a ring array.
[0020] By adopting the above technical solution, multi-point temperature measurement can be achieved by increasing the number of thermocouple wires, the number of armored sleeves and insulating thermal conductive layers can be increased to protect multiple thermocouple wires, and the number of first outer ring color labels, second outer ring color labels, first inner ring color labels, second inner ring color labels, terminal blocks and clamping screws can be increased to facilitate the assembly and disassembly of multiple thermocouple wires.
[0021] Furthermore, a first clamp and a second clamp are respectively fitted onto the outside of the plurality of armored sleeves.
[0022] By adopting the above technical solution, the workers can reinstall the first or second clamp, thereby pressing the armored sleeve onto the cable tray, further improving stability and preventing the armored sleeve and thermocouple wire from falling off.
[0023] In summary, the present invention has the following main advantages:
[0024] 1. This utility model, through the design of a terminal block, clamping screws, and a wiring bracket, allows for easy replacement of damaged thermocouple wires. When a thermocouple wire is damaged, the corresponding clamping screw is loosened, allowing the damaged armor sheath, insulating thermal layer, and thermocouple wire to be removed. A new armor sheath, insulating thermal layer, and thermocouple wire are then inserted into the wiring bracket. The wiring bracket facilitates the neat arrangement of the thermocouple wires, preventing them from becoming tangled or knotted in the junction box, thus avoiding difficulties in disassembly and assembly. Finally, the corresponding clamping screw is tightened, pressing the thermocouple wire firmly into the terminal block to conduct current. This design allows for convenient and individual replacement of damaged thermocouple wires, making the operation simple and convenient.
[0025] 2. This utility model, through the setting of a first outer ring color label, a second outer ring color label, a first inner ring color label, and a second inner ring color label, allows for easy disassembly and assembly of armored sleeves and thermocouple wires when aligning the holes at the bottom of the cable holder with the second outer ring color label or the second inner ring color label. Then, by operating the clamping screws corresponding to the first outer ring color label and the first inner ring color label, the disassembly and assembly of a specific armored sleeve and thermocouple wire can be completed. This facilitates locating the corresponding clamping screw, making disassembly and assembly easier and avoiding interference from other clamping screws; it is convenient and quick.

Detailed Implementation
[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0033] The embodiments of this utility model will be described below based on its overall structure.
[0034] Example 1
[0035] A high-performance multi-point temperature sensing armored thermocouple, such as Figures 1-4 As shown, the device includes a junction box 1. A first outer ring color label 8 and a first inner ring color label 10 are respectively provided on the upper surface of the outer surface of the junction box 1. A second outer ring color label 9 and a second inner ring color label 11 are respectively provided on the lower surface of the outer surface of the junction box 1. The first outer ring color label 8 is located below the first inner ring color label 10, and the second outer ring color label 9 is located above the second inner ring color label 11. A ribbon cable holder 14 passes through the bottom of the junction box 1. The ribbon cable holder 14 is stepped. A terminal block 12 is installed inside the junction box 1. Thermocouple wires 4 are detachably connected to the terminal block 12. The terminal block 12 is made of copper. A clamping screw 13 passes through the upper sides of both sides of the junction box 1, and the clamping screw 13 abuts against the thermocouple wires 4. When a thermocouple wire 4 is damaged, the worker first removes the screw and then takes the junction box 1 out of the container. At this time, the worker finds the damaged thermocouple wire 4. The staff then located the second outer ring color label 9 or the second inner ring color label 11 corresponding to the damaged thermocouple wire 4. They then loosened the clamping screws 13 corresponding to the first outer ring color label 8 and the first inner ring color label 10. At this point, the staff could remove the damaged armored sleeve 3, the insulating thermally conductive layer 5, and the thermocouple wire 4. The staff then inserted the new armored sleeve 3, the insulating thermally conductive layer 5, and the thermocouple wire 4 into the hole of the cable tray 14. The cable tray 14 facilitates the neat arrangement of the thermocouple wire 4, preventing it from becoming tangled and knotted in the junction box 1, thus affecting disassembly and assembly. After insertion, the staff located the second outer ring color label 9 or the second inner ring color label 11 corresponding to the new thermocouple wire 4. They then tightened the clamping screws 13 corresponding to the first outer ring color label 8 and the first inner ring color label 10, pressing the thermocouple wire 4 firmly into the junction box 12 to connect the current.
[0036] See Figures 1-5In the above embodiment, flange plates 2 are connected to both sides of the junction box 1, and a thermocouple wire 4 passes through the bottom of the cable tray 14. An armored sleeve 3 is connected to the outer surface of the thermocouple wire 4 through an insulating and heat-conducting layer 5. The armored sleeve 3 is made of stainless steel, and the insulating and heat-conducting layer 5 is made of magnesium oxide powder. Multiple armored sleeves 3, thermocouple wires 4, insulating and heat-conducting layers 5, first outer ring color labels 8, second outer ring color labels 9, first inner ring color labels 10, second inner ring color labels 11, junction boxes 12, and clamping screws 13 are provided. Multiple armored sleeves 3, thermocouple wires 4, insulating and heat-conducting layers 5, first outer ring color labels 8, second outer ring color labels 9, first inner ring color labels 10, second inner ring color labels 11, junction boxes 12, and clamping screws 13 are arranged in a ring. The junction box 1 is arranged in an array. The worker passes the junction box 1 through the top window of the container and then uses bolts and flange plate 2 to limit the junction box 1 to the container. At this time, multiple armored sleeves 3, thermocouple wires 4 and insulating thermal conductive layer 5 are submerged in the material inside the container. Due to the large number of thermocouple wires 4, multi-point temperature measurement of the material inside the container can be achieved. During this process, the armored sleeves 3 protect the thermocouple wires 4 from being crushed or corroded. The insulating thermal conductive layer 5 fills the gap between the thermocouple wires 4 and the armored sleeves 3. First, it has an insulating effect, preventing the current on the thermocouple wires 4 from being conducted to the armored sleeves 3 and causing short circuits. Second, it has a thermal conductive effect, accelerating the heat conduction by filling the gaps, thus facilitating the thermocouple wires 4 to measure the temperature of the material.
[0037] Example 2
[0038] Based on the above embodiment one, in order to increase the stability of thermocouple installation, the following settings are now adopted.
[0039] See Figure 1 and Figure 2 In the above embodiment, a first clamp 6 and a second clamp 7 are respectively fitted onto the outside of multiple armored sleeves 3. The operator puts the first clamp 6 or the second clamp 7 back on, thereby pressing the armored sleeve 3 onto the cable tray 14, further improving stability and preventing the armored sleeve 3 and thermocouple wire 4 from falling off.
[0040] The implementation principle of this utility model is as follows: First, the worker passes the junction box 1 through the top window of the container, and then uses bolts and flange plate 2 to limit the junction box 1 on the container. At this time, multiple armored sleeves 3, thermocouple wires 4 and insulating heat-conducting layer 5 are submerged in the material inside the container. Since there are many thermocouple wires 4, multi-point temperature measurement of the material inside the container can be achieved. During this process, the armored sleeves 3 protect the thermocouple wires 4 to prevent them from being crushed or corroded. The insulating heat-conducting layer 5 fills the gap between the thermocouple wires 4 and the armored sleeves 3. First, it has an insulating effect to prevent the current on the thermocouple wires 4 from being conducted to the armored sleeves 3 and causing short circuits. Second, it has a heat-conducting effect. By filling the gap, the heat conduction can be accelerated, which makes it easier for the thermocouple wires 4 to measure the temperature of the material.
[0041] When a thermocouple wire 4 is damaged, the worker first removes the bolt and then takes the junction box 1 out of the container. At this time, the worker finds the damaged thermocouple wire 4 and then removes the first clamp 6 or the second clamp 7. After that, the worker finds the second outer ring color label 9 or the second inner ring color label 11 corresponding to the damaged thermocouple wire 4. Then, the worker loosens the clamping screws 13 corresponding to the first outer ring color label 8 and the first inner ring color label 10. At this time, the worker can pull off the damaged armored sleeve 3, the insulating thermal conductive layer 5 and the thermocouple wire 4.
[0042] The workers then insert the new armored sleeve 3, the insulating thermal conductive layer 5, and the thermocouple wire 4 into the hole of the cable tray 14. The cable tray 14 is designed to facilitate the neat arrangement of the thermocouple wire 4, preventing it from getting tangled or knotted in the junction box 1, which would affect disassembly and assembly. After insertion, the workers locate the second outer ring color label 9 or the second inner ring color label 11 corresponding to the new thermocouple wire 4. Then, the workers tighten the clamping screws 13 corresponding to the first outer ring color label 8 and the first inner ring color label 10, pressing the thermocouple wire 4 into the junction box 12 to conduct current. Finally, the workers reinstall the first clamp 6 or the second clamp 7, thereby pressing the armored sleeve 3 onto the cable tray 14, further improving stability and preventing the armored sleeve 3 and the thermocouple wire 4 from falling off.
