[0027] First embodiment

[0028] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in, Figure 1 This is a structural schematic diagram of a first embodiment of a hot blast stove flue safety monitoring device provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the internal structure of the chimney is shown; Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. A hot blast stove flue safety monitoring device comprises: a smoke exhaust component 1, the smoke exhaust component 1 comprises a chimney 11, and a discharge port 12 is fixedly connected to the surface of the chimney 11;

[0029] A vertical movement drive assembly 2, which is disposed at the top of the chimney 11 and includes a rotating rod 21, a suspension rope 22, and a drive motor 23;

[0030] A sealed camera assembly 3 is provided inside the chimney 11 and includes a sealing plate 31, a connecting cover 32, and a camera 33;

[0031] The position limiting and shock absorbing component 4 is arranged inside the chimney 11 , and the position limiting and shock absorbing component 4 includes a spring telescopic rod 41 , a shock absorbing block 42 and a position limiting ring 43 .

[0032] The exhaust port 12 is fixedly connected to the outer surface of the chimney 11 near the top end, and the chimney 11 and the exhaust port 12 are internally connected. The flue gas entering the chimney 11 flows upward and is then discharged into the atmosphere through the exhaust port 12. The function of the up and down moving drive component 2 is to realize the up and down movement of the sealing shooting component 3. The function of the sealing shooting component 3 is to perform video monitoring of the interior of the chimney 11 while sealing. The function of the limit shock absorption component 4 is to limit and absorb shock, thereby increasing the stability of the movement of the sealing shooting component 3.

[0033] The rotating rod 21 is movably mounted on the top of the chimney 11 , the hanging rope 22 is movably connected to the outer surface of the rotating rod 21 , and the driving motor 23 is fixedly connected to one end of the rotating rod 21 .

[0034] A square cover is fixedly connected to the top of the chimney 11, and the two ends of the rotating rod 21 are respectively rotatably connected to the inner surfaces of the left and right ends of the square cover, and four turntables are fixedly connected to the surface of the rotating rod 21. Each two turntables form a group, and there are two hanging ropes 22. The two hanging ropes 22 are respectively wrapped around the surface of the rotating rod 21 between the two turntables in each group. The driving motor 23 is fixedly connected to the left end of the rotating rod 21 and fixedly installed on the outer surface of the square cover. The driving motor 23 drives the rotating rod 21 to rotate, thereby realizing the retraction and extension of the hanging rope 22 and adjusting the release length of the hanging rope 22.

[0035] The sealing plate 31 is movably installed inside the chimney 11 , the bottom of the suspension rope 22 is fixedly connected to the top of the sealing plate 31 , the connecting cover 32 is fixedly connected to the top of the sealing plate 31 , and the camera 33 is fixedly installed on the outer surface of the connecting cover 32 .

[0036] The size of the sealing plate 31 is just right to be embedded in the inside of the chimney 11. The connecting cover 32 is square in shape and has a groove inside. The bottom of the two hanging ropes 22 is fixedly connected to the top of the sealing plate 31 through the inside of the connecting cover 32. There are four cameras 33, which are respectively fixedly installed on the surfaces of the four ends of the connecting cover 32. By retracting and extending the hanging ropes 22, the sealing plate 31 can be driven to move up and down, so that the cameras 33 can shoot and monitor the inside of the chimney 11.

[0037] One end of the spring telescopic rod 41 is fixedly connected to the outer surface of the connecting cover 32 , and the shock absorbing block 42 is fixedly connected to the other end of the spring telescopic rod 41 . The shock absorbing block 42 is movably connected to the inner surface of the chimney 11 .

[0038] There are four spring telescopic rods 41 and four shock-absorbing blocks 42. Each of the four spring telescopic rods 41 is composed of a spring movably installed inside a telescopic rod. One end of the four telescopic rods is respectively fixedly connected to the surfaces of the four ends of the connecting cover 32 on the top of the four cameras 33.

[0039] The top of the shock absorbing block 42 is movably connected to a limiting ring 43 , and the limiting ring 43 is fixedly connected to the inner surface of the top of the chimney 11 .

[0040] The four shock-absorbing blocks 42 are respectively fixedly connected to the other ends of the four spring telescopic rods 41. Under the action of the springs, the spring telescopic rods 41 give the shock-absorbing blocks 42 a thrust, so that the shock-absorbing blocks 42 are always connected to the inner surface of the chimney 11, thereby achieving the shock-absorbing effect.

[0041] The working principle of the hot blast stove flue safety monitoring device provided by the utility model is as follows:

[0042] The driving motor 23 is started to drive the rotating rod 21 to rotate and loosen the hanging rope 22. The sealing plate 31 gradually loses the upward pulling force and moves downward. The camera 33 is started to shoot the interior of the chimney 11. In this process, due to the elastic force of the spring in the spring telescopic rod 41, the shock absorbing block 42 is always connected to the inner surface of the chimney 11. When the sealing plate 31 shakes, the spring telescopic rod 41 expands and contracts, reducing the vibration amplitude of the sealing plate 31.

[0043] Compared with related technologies, the hot blast stove flue safety monitoring device provided by the present invention has the following beneficial effects:

[0044] The utility model provides a hot blast stove flue safety monitoring device, which can seal the top of the chimney 11 by connecting a sealing plate 31 to the bottom of a connecting cover 32, effectively preventing impurities from adhering to the camera 33, and can reel in the hanging rope 22 by driving the rotating rod 21, thereby driving the sealed shooting component 3 to move up and down to perform video monitoring of the interior of the chimney 11, and at the same time, can limit the sealed shooting component 3 by the limiting shock-absorbing component 4 to prevent it from shaking during movement.

The rotating shaft in the rotating motor 52 is fixedly connected to the center of the top of the rotating plate 51 through the sealing plate 31, and the rotating motor 52 is fixedly installed inside the connecting cover 32.

[0049] The working principle of the hot blast stove flue safety monitoring device provided by the utility model is as follows:

[0050] Start the rotating motor 52 to drive the rotating plate 51 to rotate and scrape off the impurities on the bottom of the sealing plate 31. When the sealing plate 31 moves downward, the rotating plate 51 rotates and its two ends are connected to the inner surface of the chimney 11, thereby scraping off the impurities on the inner surface of the chimney 11.
