[0019] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a smoke detection device for a boiler includes a detection device body 1, a connecting pipe 2 is installed on one side surface of the detection device body 1, an air intake pipe 3 is arranged at one end of the connecting pipe 2, a handle 5 is fixed to the bottom end surface of the detection device body 1, a display screen 4 is arranged on the top of the front surface of the detection device body 1, and heat dissipation grooves 6 are evenly arranged on the bottom of the other side surface of the detection device body 1. A cleaning component is arranged inside the connecting pipe 2, and the cleaning component includes cleaning scrapers 7 symmetrically arranged inside the connecting pipe 2, and fixing rings 16 are symmetrically fixed to the outer sides of the ends of the two cleaning scrapers 7, and mounting ring grooves 17 for the fixing ring 16 to rotate are symmetrically opened on the inner wall of the end of the connecting pipe 2, and the fixing ring 1 The inner diameter of 6 is equal to the inner diameter of the end of the connecting pipe 2, and the outer surfaces of the openings at both ends of the fixing ring 16 are both inclined surfaces. A connecting magnetic block 9 is installed on the outer side of the middle part of the two cleaning scrapers 7. A limiting ring groove 10 for the cleaning scraper 7 to engage is opened on the inner wall of the middle part of the connecting pipe 2. A mounting magnetic ring 8 is sleeved on the outer side of the middle part of the connecting pipe 2. The inner surface of the mounting magnetic ring 8 is magnetically connected to the surface of the connecting magnetic block 9. A limiting block 11 is installed at an equal angle on the outer surface of the middle part of the connecting pipe 2. One end of the mounting magnetic ring 8 is limitedly engaged to the inner side of the limiting block 11, which is convenient for workers to regularly clean the inner wall of the connecting pipe 2, so that the inner wall of the connecting pipe 2 is not easy to be attached with soot, thereby avoiding affecting the detection results of the flue gas, and having good practicality.

[0020] like Figure 1 and Figure 2As shown, a protective component is provided on the outside of one end of the connecting pipe 2, and the protective component includes a protective sleeve 12 arranged on the outside of one end of the connecting pipe 2, and a heat insulating cotton 13 is provided on the inner surface of the protective sleeve 12, and the surface of the heat insulating cotton 13 is fitted and connected with the outer surface of one end of the connecting pipe 2, and installation strips 14 are symmetrically fixed on both ends of the protective sleeve 12, and Velcro 15 is provided on both side surfaces of the two installation strips 14, and the two installation strips 14 are connected by pasting the installation strips 14, and the surface length of the heat insulating cotton 13 is equal to the surface length of the protective sleeve 12, and the heat insulating cotton 13 is bonded and connected to the protective sleeve 12, which is convenient for protecting the outside of one end of the connecting pipe 2, so that workers are not prone to accidental touch and burns during detection operations, thereby improving the safety of operation and having a good practical effect.

[0021] The utility model provides a smoke detection device for a boiler, and the specific working principle is as follows: when the inner wall of the connecting pipe 2 needs to be cleaned, the utility model first holds the mounting magnetic ring 8 so that the mounting magnetic ring 8 rotates outside the connecting pipe 2. At this time, one end of the mounting magnetic ring 8 will be limited and engaged to the inner side of the limit block 11, so that the mounting magnetic ring 8 will not be easily displaced during the rotation process. At the same time, the mounting magnetic ring 8 will drive the cleaning scraper 7 to rotate inside the connecting pipe 2 through the connecting magnetic block 9. At this time, the two cleaning scrapers 7 will be limited to the inner wall of the connecting pipe 2 through the mounting ring groove 17. When the two cleaning scrapers 7 rotate, they will clean the inner wall of the connecting pipe 2, so that the smoke ash attached to the inner wall of the connecting pipe 2 can be scraped off. The operation is convenient and quick, which is convenient to improve the accuracy of smoke detection, the functionality is improved, and the practicality is good. When the protective component is installed in the early stage, the utility model first pushes the heat insulation cotton 13 moves toward the inner surface of the protective sleeve 12, so that the heat insulating cotton 13 can be bonded and installed on the inner surface of the protective sleeve 12, and then the protective sleeve 12 is covered on the outside of one end of the connecting pipe 2, so that the surface of the heat insulating cotton 13 is fitted and connected with the outer surface of one end of the connecting pipe 2, and then the installation cloth strips 14 at both ends of the protective sleeve 12 are pulled, so that the surfaces of the two installation cloth strips 14 are gradually close to each other, until the Velcro 15 on the surfaces of the two installation cloth strips 14 are glued and connected, so that the protective sleeve 12 can be limitedly sleeved on the outside of one end of the connecting pipe 2. When the detection device detects the flue gas, the flue gas in the boiler will be transported to the inside of the connecting pipe 2 through the air intake pipe 3. At this time, the flue gas will have temperature, which will increase the surface temperature of the connecting pipe 2. At this time, the protective sleeve 12 and the heat insulating cotton 13 can achieve the purpose of heat insulation. When people perform flue gas detection, they will not be accidentally burned, which improves the safety of operation and has a good practical effect.
