[0002] With the advancement of science and technology, temperature measurement technology has developed rapidly, and has formed a development trend from point to line, from line to surface; from surface to inside, from wired to wireless. Among the two major categories of products, contact and non-contact, contact thermocouples, which are large in quantity and wide in scope, have developed rapidly in the development of modern technology. Thermocouples have become the most widely used temperature sensing components in industrial production and scientific research due to their stable performance, accurate and reliable, simple structure, easy use, wide temperature measurement range, and remote signal transmission.

[0003] In the prior art, when measuring the temperature of a gasifier, a thermocouple protection sleeve is required. The length of the thermocouple protection sleeves on the market is fixed. In actual application, if the size purchased by the user deviates from the temperature measurement height, the accuracy of the temperature measurement will be affected, and the user will need to repurchase it, which will increase the cost of use. In addition, the lengths of the thermocouple protection sleeves used in different gasifiers are also different.

[0004] Therefore, a new type of thermocouple protection sleeve is proposed. Utility Model Content

[0024] like Figure 1-3As shown, a new type of thermocouple protection sleeve includes a fixed shell 1, a connecting tube 2 is provided at the bottom of the fixed shell 1, a temperature measuring tube 3 is provided on the internal thread of the connecting tube 2, a round tube 4 is provided inside the fixed shell 1 and the temperature measuring tube 3, a flange 5 is provided on the top of the round tube 4, a protective tube 6 is provided on the top of the flange 5, a threaded tube 7 is provided on the internal thread of the protective tube 6, a thermocouple junction box 8 is provided on the top of the threaded tube 7, a transmission mechanism 9 for adjusting the height of the round tube 4 is provided inside the fixed shell 1, and an auxiliary mechanism 10 for limiting the transmission of the transmission mechanism 9 is provided on one side of the fixed shell 1. The transmission mechanism 9 includes a T-shaped column 902, which is rotatably installed inside the fixed shell 1, a gear 903 is installed on the outer wall of the T-shaped column 902, a tooth groove 901 is provided on the outer wall of the round tube 4, and the gear 903 is meshed with the tooth groove 901. In this embodiment, When in use, if there is a requirement for the height of the gasifier temperature measurement, the auxiliary mechanism 10 can release the limit of the T-shaped column 902, and by pulling the round tube 4 upward, the tooth groove 901 drives the gear 903 to rotate. When the position adjustment is completed, the rotation of the T-shaped column 902 is limited by the auxiliary mechanism 10. The position of the round tube 4 can be limited by rotating the thermocouple junction box 8, which will drive the threaded tube 7 to rotate in the protective tube 6 and drive the thermocouple junction box 8 to move longitudinally. The height of the thermocouple junction box 8 can be adjusted. When carrying the whole, the round tube 4 can be separated from the contact between the temperature measuring tube 3 and the gear 903, the threaded tube 7 is separated from the protective tube 6, and the connecting tube 2 is threadedly connected to the temperature measuring tube 3, and the contact can be reduced, that is, the occupied space is reduced, so that it can adapt to different gasifier temperature measurement heights, reduce the cost of use, and facilitate its assembly and disassembly, easy to carry, and highly practical.

[0025] like Figure 2 As shown, the number of T-shaped columns 902 and gears 903 is set to two and symmetrically distributed, and the two gears 903 are both engaged with the tooth grooves 901. In this embodiment, the number and orientation of the T-shaped columns 902 and gears 903 are set to enhance the stability of the transmission height adjustment of the circular tube 4, and facilitate the assembly and disassembly of the circular tube 4.

[0026] like Figure 2 As shown, two T-shaped circular grooves are provided on the inner side wall of the fixed shell 1, and two circular holes are penetrated on the front side of the fixed shell 1. The T-shaped column 902 is rotatably mounted on the inner walls of the T-shaped grooves and the circular holes. In this embodiment, the T-shaped column 902 is rotationally limited by the T-shaped circular grooves to prevent it from disengaging, so that the T-shaped column 902 can rotate in the T-shaped circular grooves and the circular holes.

[0027] like Figure 1-3As shown, the auxiliary mechanism 10 includes two cylinders 1003, a rectangular groove 1001 is opened on the front side of the fixed shell 1, and the two cylinders 1003 are installed on the inner wall of the rectangular groove 1001, and the outer walls of the two cylinders 1003 are sleeved with springs 1004, and two sliders 1005 are slidably installed on the outer walls of the two cylinders 1003, and the sliders 1005 are slidably installed on the inner wall of the rectangular groove 1001. In this embodiment, when the two sliders 1005 are pushed to slide close to each other on the two cylinders 1003, the two springs 1004 are compressed. When the two sliders 1005 are released, they are reset under the reset elastic force of the springs 1004.

[0028] like Figure 3 As shown, the front ends of the two T-shaped columns 902 extend outside the fixed shell 1, and the front sides of the two extended end T-shaped columns 902 are installed with connecting wheels 1002, and the surfaces of the two sliders 1005 are installed with blocking blocks 1006, and the connecting wheels 1002 are in contact with the blocking blocks 1006. In this embodiment, when the two sliders 1005 move toward each other, the two blocking blocks 1006 move accordingly and break away from the contact with the two connecting wheels 1002, that is, the limiting of the two connecting wheels 1002 is released. Conversely, under the elastic potential energy of the two springs 1004, the two blocking blocks 1006 limit the two connecting wheels 1002.

[0029] like Figure 3 As shown, a connecting block 1007 is installed on the front side of the two sliders 1005, and anti-slip grooves are engraved on the surface of the connecting block 1007. In this embodiment, the setting of the two sliders 1005 facilitates the pushing of the two sliders 1005, and the setting of the protective grooves increases the friction with the hands of the staff.

[0030] In summary, when in use, if there is a requirement for the height of the gasifier temperature measurement, the auxiliary mechanism 10 can release the limit on the T-shaped column 902, and by pulling the round tube 4 upward, the tooth groove 901 drives the gear 903 to rotate. When the position adjustment is completed, the rotation of the T-shaped column 902 is limited by the auxiliary mechanism 10. The position limit of the round tube 4 can be achieved by rotating the thermocouple junction box 8, which will drive the threaded tube 7 to rotate in the protective tube 6 and drive the thermocouple junction box 8 to move longitudinally. The height of the thermocouple junction box 8 can be adjusted. When carrying the whole, the round tube 4 can be separated from the contact between the temperature measuring tube 3 and the gear 903, the threaded tube 7 is separated from the protective tube 6, and the connecting tube 2 is threadedly connected to the temperature measuring tube 3, and the contact can be reduced, which reduces the occupied space. It can adapt to different gasifier temperature measurement heights, reduce the cost of use, and facilitate its assembly and disassembly. It is easy to carry and has strong practicality. The setting enhances the stability of the height adjustment of the circular tube 4 and facilitates the assembly and disassembly of the circular tube 4. The T-shaped column 902 is limited in rotation by the T-shaped groove to prevent it from disengaging, so that the T-shaped column 902 can rotate in the T-shaped groove and the circular hole. When the two sliders 1005 are pushed to slide close to each other on the two cylinders 1003, the two springs 1004 are compressed. When the two sliders 1005 are released, they are reset under the restoring elastic force of the springs 1004. When the two sliders 1005 move close to each other, the two blocking blocks 1006 move accordingly and disengage from the contact with the two connecting wheels 1002, that is, the limiting of the two connecting wheels 1002 is released. Conversely, under the elastic potential energy of the two springs 1004, the two blocking blocks 1006 limit the two connecting wheels 1002. The setting of the two sliders 1005 makes it easy to push the two sliders 1005, and the setting of the protective pattern increases the friction in contact with the hands of the staff.
