[0001] The utility model relates to the technical field of online measurement devices for boiler temperature fields, in particular to a flexibly arranged temperature measurement device. Background Art

[0002] The flue gas temperature of the boiler is an important parameter for the heat exchange of the heating surface. Accurately measuring the flue gas temperature field distribution can effectively determine the heat absorption status of each level of the heating surface. At present, there are many methods for online detection of power plant boiler temperature. Relatively speaking, the temperature measurement method of contact thermocouple has high accuracy and simple operation.

[0003] Due to the large size of the boiler furnace, in order to obtain the temperature field distribution of a certain cross-section, a large number of thermocouples need to be installed on the cross-section, and the thermocouples need to be flexibly arranged in the furnace according to the required number. Usually, a full-hall scaffolding needs to be erected on site during installation. The traditional installation scheme has a large workload and a long construction period. At the same time, the rooting and fixing of the thermocouple support device become difficulties in implementation. The traditional thermocouple arrangement method cannot be flexibly adjusted and cannot be applied to flues with different structures. Utility Model Content

[0019] The utility model discloses a temperature measuring device with flexible arrangement, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4, including a temperature measuring module, a temperature measuring fixing device and a wall-penetrating sealing device. The temperature measuring module is arranged at the upper and lower ends of the furnace. The temperature measuring module includes a thermocouple 1, a compensation wire 2 and a temperature measuring instrument 3. The temperature measuring fixing device includes a partition 6, a stainless steel wire rope 4, a stainless steel wire 5, a lock buckle 7, a rope tightener 8 and a fixing hook 9 arranged on the upper and lower sides of the furnace. The wall-penetrating sealing device includes a sleeve 10 and a thermal insulation cotton 11. The thermocouple 1 passes through the boiler wall plate through the sleeve 10 and is distributed inside the furnace. The thermocouple 1 is tied to the stainless steel wire rope 4 on the inner side of the furnace through the stainless steel wire 5. The thermocouple 1 is connected to the temperature measuring instrument 3 on the outer side of the furnace through the extension of the compensation wire 2. In this embodiment, the compensation wire 2 adopts a stainless steel compensation wire, and the arrangement of the temperature measuring module changes according to the structure of the flue.
