A furnace window 2 is provided on the furnace wall of the calcium carbide furnace body 1. A window door 3 is provided on the furnace window 2 in a closable manner. It is characterized in that a high-temperature resistant camera 14 is installed outside the furnace window 2 in a telescopic manner through a scissor bracket;

[0026] The scissor bracket includes at least two pairs of long connecting rods 9 that cross at the center and are rotatably connected. Short connecting rods 8 are rotatably installed at the ends of the long connecting rods 9. One end of the short connecting rod 8 is rotatably installed on a cylinder 7, and the other end of the short connecting rod 8 is rotatably installed on a mounting plate 12; the two pairs of long connecting rods 9 that cross at the center and are rotatably connected are symmetric about the cylinder 7;

[0027] The scissor bracket realizes telescoping through the telescoping of the small arm of the cylinder 7.

[0028] Working principle

[0029] When in use, first open the furnace window, start the cylinder, extend the scissor bracket into the calcium carbide furnace. When rotation is required, turn the handle, and then turn the worm. The worm drives the worm wheel to rotate, and then drives the camera to rotate, so as to comprehensively observe the situation inside the furnace.

[0030] In some embodiments, see Figure 2 as shown, the cylinder 7 is fixed on the worm wheel 5. The worm wheel 5 is rotatably installed on a worm wheel shaft through a bearing. The worm wheel shaft is fixed on a base 4. A matching worm 6 is engaged with the worm wheel 5.
