Technical Field
[0001] This utility model relates to the field of temperature measuring equipment technology, specifically to a boiler temperature measuring device. Background Technology
[0002] During boiler operation, operators cannot accurately determine the insertion depth of the temperature element and must adjust the insertion depth only after receiving the temperature value remotely. When coking occurs inside the boiler, the threaded connection between the temperature element's protective sleeve and the junction box is prone to stripping during the descaling process. Furthermore, the temperature element's wiring disc base is secured with screws, making it susceptible to loss or damage. Utility Model Content

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0019] Example like Figures 1 to 7As shown, the boiler temperature measuring device of this utility model includes: a protective sleeve 3, a wiring protection box 4, a wiring base 5, and a temperature measuring core 12. Both ends of the wiring protection box 4 are detachably connected to the protective sleeve 3 and the wiring base 5, respectively. One end of the temperature measuring core 12 is detachably connected to the wiring base 5, and the other end of the temperature measuring core 12 passes through the wiring protection box 4 and the protective sleeve 3 in sequence, with the wiring base 5 located inside the wiring protection box 4. The protective sleeve 3 and the temperature measuring core 12 are inserted into the boiler through the side wall, and a scale 1 is provided on the outer wall of the protective sleeve 3 to measure the distance the protective sleeve 3 and the temperature measuring core 12 are inserted into the boiler. Figure 3 As shown, the wiring base 5 is provided with quick-connect terminals 8, a display integrated board 10, and a through hole 17. The quick-connect terminals 8 are connected to the display integrated board 10 via cables 16. The cables 16 on the quick-connect terminals 8 also pass through the through hole 17 and are connected to the temperature sensing core 12, so that the temperature inside the boiler can be displayed in real time on the display integrated board 10. In this embodiment, the wiring base 5 is made of ceramic material, which has a stable structure and good insulation performance.
[0020] In this embodiment, by setting a scale 1 on the outer wall of the protective sleeve 3, the distance between the protective sleeve 3 and the temperature measuring core 12 inserted into the boiler can be accurately determined. By setting a quick-connect terminal 8 and a display integrated board 10 on the wiring base 5, and connecting the quick-connect terminal 8 to the display integrated board 10 and the temperature measuring core 12 respectively through the cable 16, the temperature inside the boiler can be displayed in real time on the display integrated board 10. Furthermore, the depth position of the temperature measuring core 12 inside the boiler can be adjusted according to the real-time temperature data, thereby improving the accuracy of the temperature measurement inside the boiler.
[0021] like Figure 2 As shown, one end of the protective sleeve 3 is provided with a boss 31, and the outer side of the boss 31 is provided with a groove 11. For example... Figure 5 As shown, one end of the wiring protection box 4 has a second inner wall 42 and a first inner wall 41 arranged sequentially from the inside to the outside, and a cavity 43 is formed between the second inner wall 42 and the first inner wall 41. A ball bearing 7 is provided on the first inner wall 41. When the boss 31 is nested into the cavity 43, the ball bearing 7 is embedded in the groove 11 to achieve quick plug-in connection between the protective sleeve 3 and the wiring protection box 4. When coking occurs inside the boiler and needs to be cleaned, the wiring protection box 4, together with the wiring base 5 and the temperature measuring core 12, can be easily removed to avoid damage to the temperature measuring device during the coking process. The quick-connect connection also allows for periodic inspection of the temperature protection sleeve, facilitating timely maintenance and replacement.
[0022] like Figure 1 and Figure 5 As shown, the side wall of the wiring protection box 4 is provided with a through-hole 6 to allow the cable 16 on the wiring base 5 to be led out to the external DCS controller.
[0023] like Figure 4 and Figure 5 As shown, the second inner wall 42 is provided with a first internal thread 18, and the outer wall of the wiring base 5 is provided with a first external thread 14. The first external thread 14 matches the first internal thread 18 to realize the threaded connection between the wiring base 5 and the wiring protection box 4.
[0024] like Figure 6 As shown, the inner wall of the wiring base 5 is provided with a second internal thread 19, and the end of the temperature measuring core 12 is provided with a second external thread 20. The second internal thread 19 and the second external thread 20 are matched to realize the threaded connection between the wiring base 5 and the temperature measuring core 12.
[0025] In this embodiment, the wiring base 5 is connected to the wiring protection box 4 and the temperature measuring core 12 through internal and external thread engagement, which facilitates disassembly and assembly, improves the reliability of the connection, and avoids the loss of components.
[0026] like Figure 3 and Figure 4 As shown, the wiring base 5 is also provided with a rotation reserved hole 9. The rotation reserved hole 9 is used as a force point to facilitate the rotation of the wiring base 5.
[0027] like Figure 1 As shown, the end of the wiring protection box 4 furthest from the protective sleeve 3 is provided with multiple fixing holes 2 and screws 15. The fixing holes 2 and screws 15 are used to install a transparent viewing lens, so that the wiring base 5 is encapsulated inside the wiring protection box 4. Furthermore, the end of the wiring protection box 4 is also provided with a mounting groove 13, located inside the fixing holes 2. A sealing ring is provided in the mounting groove 13 to achieve a sealed connection between the transparent viewing lens and the wiring protection box 4, preventing external debris from entering the wiring protection box 4.
