[0026] The thermocouple body 1 and the connecting rod 11 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0027] A high-temperature leak-proof thermocouple for a gasifier comprises: a thermocouple body 1, to which a connecting rod 11 is connected;

[0028] The top surface of the connecting rod 11 is provided with a chute 12 on both sides, and a limit block 13 is provided on both sides of the chute 12. A socket 14 is provided in the middle of the top surface of the connecting rod 11, and a connecting terminal 15 is installed on the inner side of the connecting rod 11.

[0029] A mounting structure 2 is installed on the connecting rod 11, and the mounting structure 2 includes a top cover 21. The top cover 21 is installed on the top surface of the connecting rod 11. Inclined surfaces 22 are provided at both ends of the top cover 21. A sealing ring 23 is bonded to the bottom surface of the top cover 21. A pull block 24 is movably installed on the upper side of the top cover 21. Slide blocks 25 are integrally formed at both ends of the pull block 24. A plug column 26 is integrally formed on the bottom surface of the top cover 21, and a card slot 27 is provided on the bottom surface of the top cover 21.

[0030] Furthermore, a support structure 3 is installed on the inner side of the connecting rod 11, and the support structure 3 includes a fixed column 31, which is fixedly installed on the inner bottom surface of the connecting rod 11, and a movable column 32 is movably installed inside the fixed column 31, and the bottom end of the movable column 32 is fixedly connected to a spring 33, and the top end of the movable column 32 is fixedly connected to a block 34.

[0031] Furthermore, the connecting terminal 15 is clamped inside the clamping block 34 .

[0032] Furthermore, the bottom surface of the top cover 21 is adapted to the top surface of the connecting rod 11 , and the sealing ring 23 is in contact with the top surface of the connecting rod 11 .

[0033] Furthermore, the slider 25 is slidably installed inside the slide groove 12 , and the plug post 26 is inserted into the socket 14 .

[0034] Furthermore, one end of the spring 33 is fixedly connected to the inner wall of the fixing column 31, and the upper end of the clamping block 34 is clamped in the inner part of the clamping groove 27.

[0035] Working principle: Before use, the wire can be connected to the thermocouple wire through the connecting terminal 15, and the connecting terminal 15 can be clamped inside the clamping block 34;

[0036] The top cover 21 is covered on the connecting rod 11 so that the plug post 26 is inserted into the plug hole 14, and the top cover 21 can be pre-fixed on the connecting rod 11.
