The overall idea is as follows:

[0027] In view of the problems in the prior art, the utility model provides a fireproof fire-fighting smoke exhaust mechanism, which comprises a pipe body 11, connecting sleeves 13 are fixedly installed at both side end portions of the pipe body 11, bypass pipes 14 are fixedly installed at the top end of each connecting sleeve 13, fixing seats 16 are fixedly installed at both side end portions of the pipe body 11, the angle of the bypass pipe 14 is adjusted, the bypass pipe 14 rotates, extrudes the connecting sleeve 13 at the side end portion, the soft material on both sides of the connecting sleeve 13 can stretch and bend, while ensuring the connection of the bypass pipe 14 and the pipe body 11, the bypass pipe 14 is rotated, the bypass pipe 14 is pulled to move to one side, the position and orientation of the bypass pipe 14 are adjusted, the connecting plate 15 is slidingly installed in the inside of each fixing seat 16, and the sleeve ring 21 is slidingly installed at the top end of each bypass pipe 14.

[0028] The top end of each collar 21 is fixedly installed with two telescopic rods 23, and the top end of each collar 21 is fixedly installed with at least two limiting rods 22. The top end of each connecting plate 15 is slidingly installed with a positioning plate 19, and the bottom end of each positioning plate 19 is fixedly installed with a spring rod 18. A fan body 17 is rotatably installed in the inside of the pipeline body 11. The connecting plate 15 is pushed to slide in the inside of the fixed seat 16, and the end of the connecting plate 15 is rotatably connected to the top end of the collar 21. The collar 21 is pressed to slide between the connecting plate 15 and the bypass pipe 14. The collar 21 is moved downward to press the top end of the telescopic rod 23, so as to force the telescopic rod 23 to be compressed. At the same time, the collar 21 drives the limiting rod 22 to move away from the end of the connecting plate 15. The inside of the pipeline body 11 is fixedly installed with a mounting frame 12.

[0029] Working principle:

[0030] Firstly, the fan body 17 in the inside of the pipeline body 11 is driven by the control box at the top end of the pipeline body 11 to rotate. The fan blades drive the airflow to flow in a fixed direction in the inside of the pipeline body 11. The indoor smoke is discharged through the pipeline body 11. At the same time, the inside of the pipeline body 11 is installed with the mounting frame 12. The side end of the mounting frame 12 is installed with a plurality of nozzles connected with the inside of the mounting frame 12. When the flame enters the inside of the pipeline body 11, the nozzles on one side of the mounting frame 12 spray misty water flow into the inside of the pipeline body 11 to intercept and block the flame entering the inside of the pipeline body 11, and to cool the pipeline body 11. The positioning plate 19 is pulled upward to slide upward. The spring rod 18 at the end of the positioning plate 19 is stretched in the inside of the connecting plate 15. The bottom end of the positioning plate 19 is provided with two symmetrically distributed protrusions. The end of the positioning plate 19 is synchronously moved away from the top end of the fixed seat 16.

[0031] Second, by pushing the connecting plate 15, the connecting plate 15 slides inside the fixed seat 16, while the end of the connecting plate 15 is rotatably connected with the top end of the sleeve ring 21, by pressing the sleeve ring 21, the sleeve ring 21 slides between the connecting plate 15 and the bypass pipe 14, the sleeve ring 21 moves downward to press the top end of the telescopic rod 23, forcing the telescopic rod 23 to compress, while the sleeve ring 21 drives the limiting rod 22 away from the end of the connecting plate 15, by rotating the bypass pipe 14, the bypass pipe 14 drives the sleeve ring 21 to rotate at the end of the connecting plate 15, while adjusting the angle of the bypass pipe 14, the bypass pipe 14 rotates to press the connecting sleeve 13 at the side end, the soft material on both sides of the connecting sleeve 13 can stretch and bend, while ensuring the connection between the bypass pipe 14 and the pipeline body 11, by rotating the bypass pipe 14, pulling the bypass pipe 14 to move to one side, adjusting the position and orientation of the bypass pipe 14, by releasing the pressure on the sleeve ring 21, the telescopic rod 23 exerts an upward force on the sleeve ring 21 under the action of the two telescopic rods 23, the sleeve ring 21 drives the limiting rod 22 to insert into the bottom end of the connecting plate 15, fixing the angle of the bypass pipe 14, while under the reverse tension of the spring rod 18, the spring rod 18 pulls the positioning plate 19 to move, the end of the positioning plate 19 inserts into the top end of the fixed seat 16, fixing the position of the connecting plate 15, fixing the position of the bypass pipe 14.

[0032] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can also be made. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
