[0025] See also Figure 1-3 , the utility model provides a technical solution:

[0026] A high temperature resistant mounting structure sensor comprises a sensor body 1;

[0027] It includes a mounting structure for installing the sensor; the mounting structure includes a protective shell 2, the material of the protective shell 2 is a nickel-based alloy, the protective shell 2 is divided into an upper cavity 3 and a lower cavity 4 by a partition, and a sleeve 5 is provided in the lower cavity 4, which passes through the upper cavity 3 and the outside of the protective shell 2, and the sensor body 1 is placed inside the sleeve 5; mounting plates 12 are symmetrically provided on both sides of the upper end of the protective shell 2, and mounting holes are opened on the mounting plates 12.

[0028] An installation structure is provided including a protective shell 2, wherein an upper cavity 3, a lower cavity 4 and a sleeve 5 for placing a sensor body 1 are provided inside the protective shell 2. By providing the protective shell 2 with a high-temperature resistant metal material, the stability of the physical and chemical properties can be maintained within a predetermined high-temperature range. At the same time, a channel is provided inside the protective shell 2 to promote heat dissipation and prevent overheating. The protective shell 2 can effectively resist the challenges brought by a high-temperature environment and improve the service life and measurement accuracy of the sensor.

[0029] See also Figure 2-3 :

[0030] The sensor body 1 is secured to the two side walls of the upper cavity 3. The securing structure comprises a securing screw 8 and a securing block 10. The securing screw 8 is threadedly mounted on the side walls of the upper cavity 3. One end of the securing screw 8 is fixedly connected to a knob 9, while the other end of the securing screw 8 is connected to the securing block 10. Both sets of securing blocks 10 are arc-shaped. A bearing 11 is embedded in one convex side wall of the securing block 10. The end of the securing screw 8 is inserted and secured to the inner race of the bearing 11.

[0031] By setting a fixing structure including a fixing screw 8 and a fixing block 10 on the side wall of the upper cavity 3, the fixing screw 8 is threadedly installed on the side wall of the upper cavity 3, a knob 9 is set at one end of the fixing screw 8, and the other end is rotatably connected to the fixing block 10. When in use, the sensor body 1 is placed in the sleeve 5, and the probe of the sensor is located outside the protective shell 2 for data acquisition. By rotating the knob 9, the two sets of fixing blocks 10 are clamped and fixed to the sensor. When the equipment is installed through the mounting plate 12 and the mounting hole, a clamping and fixing method is adopted. Different from the traditional screw fixing, the installation and disassembly of the sensor is simpler, and the installation process of the sensor is shortened; different from the traditional glue bonding method, it can better adapt to high temperature environment and is not prone to positioning failure or detachment problems.

[0032] For further information, see Figure 3 In order to increase the adaptability of the sensor in high temperature environments, this application also makes the following designs:

[0033] A fluid inlet 6 communicating with the outside is provided on one side wall of the lower cavity 4 , and a fluid outlet 7 communicating with the outside is provided on the other side wall of the lower cavity 4 .

[0034] Specifically, Example 1:

[0036] In actual use, the water pump draws coolant and transports it into the lower cavity 4 through the pipeline, which can fill the lower cavity 4 and wrap the sleeve 5. The heat inside the sensor and the protective shell 2 can be introduced into the liquid and taken out through the fluid outlet 7, thereby making the device have better high temperature resistance.

[0037] Specifically, Example 2:

[0038] The fluid inlet 6 is connected to the air outlet of the air cooler through a pipeline.

[0039] In actual use, the air cooler draws in external air, cools it, and then transports it into the lower cavity 4 through a pipe, which can fill the lower cavity 4 and wrap the sleeve 5. The heat inside the sensor and the protective shell 2 can be exchanged with the cold air. After the heat exchange is completed, the air is discharged through the fluid outlet 7, thereby making the device have better high temperature resistance.

[0040] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
