Description

Technical Field

[0001] This utility model relates to the field of solid oxide fuel cells, and in particular to a temperature sensor protection structure. Background Technology

[0002] Solid oxide fuel cells need to reach a certain temperature to generate electricity smoothly. Therefore, it is necessary to monitor the temperature at various points in the solid oxide fuel cell system and use the monitoring signals as input to control the operation of the system. Temperature sensors are usually used for monitoring during the monitoring process.

[0003] In the prior art, temperature sensors are typically mounted on a sensor mounting base, with the threads on the sensor mounting base matching the threads of the pipe. In this case, the sensing part of the temperature sensor is inserted into the pipe to monitor the temperature.

[0004] In the existing technology, temperature sensors are connected to the pipeline through threads on the mounting base. When the temperature in the pipeline is too high, the threads sinter, making it difficult to remove the mounting base and temperature sensor from the pipeline. This makes it difficult to replace or reuse the temperature sensor, resulting in a short service life. Utility Model Content

[0006] A temperature sensor protection structure includes: a temperature sensor, a conduit, and a mounting base.

[0007] An installation port is provided on the pipeline, and the mounting base is disposed at the installation port. The mounting base is a cylindrical structure with an upward opening. The bottom of the mounting base is provided with a mounting groove extending into the pipeline. The temperature sensor is installed at the opening of the mounting base, and the detection end of the temperature sensor is inserted into the mounting groove.

[0008] Optionally, the mounting base is detachably connected to the pipeline.

[0009] Optionally, the mounting base is threaded or interference-fitted with the pipeline.

[0010] Optionally, a heat insulation ring is provided between the mounting port and the mounting base.

[0011] Optionally, it also includes a clamp, which is an upward-opening cylindrical structure, and is disposed in the mounting base. The bottom of the clamp has a clamping opening that matches the temperature sensor.

[0017] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0018] This utility model provides a temperature sensor protection structure. By setting an installation groove at the bottom of the mounting base, the temperature sensor is inserted into the installation groove for temperature measurement. The deviation is calculated based on the temperature data obtained by directly inserting the temperature sensor into the pipeline, and then the deviation is compensated for the data obtained by the temperature sensor placed in the installation groove. This is used to measure the temperature in the pipeline. Compared with the traditional technology where the temperature sensor is directly inserted into the pipeline through the mounting base for temperature measurement, this embodiment provides a certain degree of heat insulation by setting an installation groove, which facilitates the removal of the temperature sensor from the mounting base and can effectively solve the problem of the short service life of temperature sensors in the prior art.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Figure 1 This is a schematic diagram of the overall structure provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the pipeline structure provided in an embodiment of the present utility model; Figure 3 This is a schematic diagram of the mounting base structure provided in an embodiment of the present utility model; Figure 4 This is a front view schematic diagram of the mounting base provided in an embodiment of this utility model; Figure 5 This is a schematic diagram of the clamp structure provided in an embodiment of the present utility model; Figure 6 This is a schematic cross-sectional view of the pipe and mounting base provided in an embodiment of this utility model. Figures 1 to 6 The temperature sensor protection structure shown includes: a temperature sensor 1, a pipe 2, and a mounting base 3. The pipe 2 has an installation port 21, and the mounting base 3 is located at the installation port 21. The mounting base 3 is an upward-opening cylindrical structure. The bottom of the mounting base 3 has a mounting groove 31 extending into the pipe 2. The temperature sensor 1 is installed at the opening of the mounting base 3, and the detection end of the temperature sensor 1 is inserted into the mounting groove 31.

[0029] In this embodiment of the invention, the temperature sensor 1 is a long strip structure with a circular mounting port 21 on the top side wall of the pipe 2. A mounting base 3 is installed at the mounting port 21, providing support for the temperature sensor 1. The mounting base 3 is a cylindrical structure with an open top. The temperature sensor 1 is inserted from the top of the mounting base 3 into the mounting groove 31, which is a long, narrow groove with a closed bottom. The detection end of the temperature sensor 1 is located within the mounting groove 31, and the circuit end of the temperature sensor 1 is located above the mounting base 3, connecting to an external circuit. The temperature sensor 1 monitors the temperature inside the pipe through the mounting groove 31. Because the mounting groove 31 provides some insulation, the temperature measured by the temperature sensor 1 may be inaccurate. This can be addressed by comparing the temperature sensor 1 beforehand by directly installing it in the pipe and comparing the temperature difference between direct measurement and measurement through the mounting groove 31. In practical application of this embodiment, the temperature difference is compensated for in the monitored temperature, thus making the temperature detected by the temperature sensor 1 in this structure more accurate. The installation slot 31 provides thermal insulation protection for the temperature sensor 1 and also provides support for the temperature sensor 1, making it easy to remove or replace the temperature sensor 1 and preventing sintering, thereby improving the service life of the temperature sensor 1.

[0030] This utility model provides a temperature sensor protection structure. By setting an installation groove 31 at the bottom of the mounting base 3, the temperature sensor 1 is inserted into the installation groove 31 for temperature measurement. The deviation is calculated based on the temperature data obtained by directly inserting the temperature sensor 1 into the pipe 2, and then the deviation is compensated for the data obtained by the temperature sensor 1 placed in the installation groove 31. This is used to measure the temperature in the pipe 2. Compared with the traditional technology where the temperature sensor 1 is directly inserted into the pipe 2 through the mounting base 3, this embodiment provides a certain degree of heat insulation by setting an installation groove 31, which facilitates the removal of the temperature sensor 1 from the mounting base 3. This can effectively solve the problem of the short service life of temperature sensors in the prior art.

[0031] Optionally, the mounting base 3 is detachably connected to the pipe 2.

[0032] For example, in this embodiment of the present invention, the mounting base 3 and the pipeline 2 are detachably connected, such as by snap-fit ​​connection or threaded connection. After a long period of use, the mounting base 3 may reach the end of its service life, or the mounting groove 31 may deform, making it difficult to insert the temperature sensor 1. By detachably connecting the mounting base 3 and the pipeline 2, the mounting base 3 can be easily replaced, thereby improving the ease of operation of this structure.

[0033] Optionally, the mounting base 3 is threaded or interference-fitted to the pipe 2.

[0034] For example, in this embodiment of the present invention, by connecting the mounting base 3 to the pipe 2 by thread or interference fit, the mounting base 3 and the pipe 2 can be connected and fixed without the need for external adhesive or welding, thereby reducing production steps, lowering production costs, and making it easy to assemble and disassemble the mounting base 3 and the pipe 2, further improving the ease of operation of this structure.

[0035] Optionally, a heat insulation ring 4 is provided between the mounting port 21 and the mounting base 3.

[0036] Exemplary, in embodiments of this utility model, such as Figure 6 As shown, by providing a heat insulation ring 4 between the mounting port 21 and the mounting base 3, excessively high temperatures can prevent the mounting base 3 from sintering with the pipeline 2. This makes it easier to separate the mounting base 3 from the pipeline 2, facilitating the replacement of the mounting base 3. The heat insulation ring 4 can be made of silicon carbide ceramic material, which has excellent high-temperature resistance and can operate for extended periods in high-temperature environments above 1000 degrees Celsius. Since the operating temperature of solid oxide fuel cells is around 800 to 1000 degrees Celsius, the use of silicon carbide ceramic for the heat insulation ring 4 ensures its excellent thermal shock resistance and chemical stability, preventing it from melting at high temperatures, thereby improving the stability of this structure.

[0037] Optionally, it also includes a clamp 5, which is an upward-opening cylindrical structure. The clamp 5 is set inside the mounting base 3, and the bottom of the clamp 5 has a clamping port 51 that matches the temperature sensor 1.

[0038] For example, in this embodiment of the present invention, by setting the clamp 5, the temperature sensor 1 can be first installed in conjunction with the clamp 5, and then the whole assembly can be placed into the mounting groove 31. The size of the clamping opening 51 matches the temperature sensor 1 and has a certain degree of elasticity, so that the temperature sensor 1 can be clamped and fixed after being inserted into the clamping opening 51. This structure is relatively convenient to operate. At the same time, the clamp 5 can limit the vertical height of the temperature sensor 1. When the temperature sensor 1 does not need to be inserted to the bottom of the mounting groove 31, the fixed height of the temperature sensor can be adjusted by adjusting the mating position of the clamping opening 51 and the temperature sensor 1, thereby improving the versatility of this structure. By setting the clamp 5, the temperature sensor 1 can be mated and fixed with the clamping opening 51. The clamping opening 51 plays a further limiting role in fixing the temperature sensor 1, making the temperature sensor 1 more stably set in the mounting base 3 for temperature measurement, thereby ensuring the accuracy of the temperature measurement results.

[0039] Optionally, expansion grooves 52 are provided on both sides of the clamping port 51.

[0040] Exemplary, in embodiments of this utility model, such as Figure 5As shown, the expansion groove 52 is a long strip structure and is connected to the clamping port 51. By setting the expansion groove 52, when the temperature sensor 1 is engaged with the clamping port 51, the deformation of the expansion groove 52 makes it easier for the temperature sensor 1 to be placed in the clamping port 51 for clamping, thereby further improving the ease of operation of this structure.

[0041] Optionally, the clamp 5 is provided with a positioning pin 53 on its side, and the inner wall of the mounting base 3 is provided with a positioning groove 32 that matches the positioning pin 53.

[0042] Exemplary, in embodiments of this utility model, such as Figure 4 and Figure 5 As shown, when installing the clamp 5 and the mounting base 3, the clamp 5 can be more securely fixed in the mounting base 3 by setting the positioning pin 53 and the positioning groove 32 to cooperate. On the other hand, during assembly, the positioning pin 53 and the positioning groove 32 can make the operator know that the clamp 5 has been installed in place, and can also reduce the time for the operator to check whether the installation is in place, thereby further improving the ease of operation of this structure.

[0043] Optionally, the side of the clamp 5 is provided with a weight reduction groove 54.

[0044] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by opening the weight reduction groove 54, the production material of the clamp 5 can be reduced. Under the premise of ensuring that the bottom of the clamp 5 can provide a clamping and fixing function for the temperature sensor 1, the weight reduction groove 54 can reduce the production cost of the clamp 5 and improve its economic efficiency.

[0045] Optionally, the top of the clamp 5 is provided with a limiting plate 55 that folds outward from the open end.

[0046] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, the limiting plate 55 is folded over the outside of the mounting base 3. By setting the limiting plate 55, on the one hand, the operator can know whether the clamp 5 is installed properly by the bend on the side of the limiting plate 55 and the top opening of the mounting base 3. On the other hand, the limiting plate 55 is similar to a handle. By setting the limiting plate 55, the operator can also install the clamp by holding the limiting plate 55, thereby further improving the ease of operation of this structure.

[0047] Optionally, clamp 5 is made of stainless steel.

[0048] For example, in this embodiment of the present invention, stainless steel has excellent heat resistance and corrosion resistance, which can prevent the clamp 5 from undergoing chemical reaction in a high-temperature environment, thereby ensuring the structural stability of the clamp 5. At the same time, stainless steel has excellent mechanical properties and can deform to a certain extent, thereby ensuring the stable installation of the temperature sensor 1 and the clamp 5.
