[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 In an embodiment of the present invention, a flue gas sampling and detection device includes a smoke sampling gun 1 consisting of a handle 101 and a sampling gun barrel 102. A sealing component 2 is provided on the outside of the sampling gun barrel 102. The sealing component 2 is used to seal the flue detection port and simultaneously control the depth of the sampling gun barrel 102 inserted into the flue.

[0020] The blocking assembly 2 includes a limiting ring block 201 , a first blocking member 202 , and a second blocking member 203 .

[0021] There are multiple limiting ring blocks 201, which are evenly distributed along the long side direction of the sampling barrel 102 and fixed to the outside of the sampling barrel 102; the first sealing piece 202 and the second sealing piece 203 are fitted and engaged with each other, and the first sealing piece 202 is sleeved on the outside of the sampling barrel 102, and the first sealing piece 202 and the second sealing piece 203 are located between the two limiting ring blocks 201. The first sealing piece 202 and the second sealing piece 203 are combined into a trumpet-shaped shielding piece, which is used to realize the sealing operation of the flue detection port and at the same time limit the position of the sampling barrel 102 inserted into the flue.

[0022] The first blocking piece 202 is composed of an inner horn rubber block 2021, an inner sleeve ring block 2022, and a first through slot 2023; the inner sleeve ring block 2022 is fixed to the inner side of the inner horn rubber block 2021, and the first through slot 2023 penetrates the inner and outer sides and both end surfaces of the inner sleeve ring block 2022 and the first through slot 2023; the inner horn rubber block 2021 and the inner sleeve ring block 2022 can be unfolded and sleeved on the outer side of the sampling gun barrel 102 through the second blocking piece 203.

[0023] The second sealing piece 203 is composed of an outer speaker rubber block 2031, an outer sleeve ring block 2032, a snap-fit fold 2033, and a second through slot 2034; the outer sleeve ring block 2032 is fixed to the inner side of the outer speaker rubber block 2031, the snap-fit fold 2033 is fixed to the outer edge of the outer speaker rubber block 2031, and the second through slot 2034 penetrates the inner and outer sides and both end faces of the outer speaker rubber block 2031, the outer sleeve ring block 2032, and the snap-fit fold 2033.

[0024] The outer horn rubber block 2031, the outer sleeve ring block 2032, and the snap-fit folded edge 2033 can be unfolded and sleeved on the outside of the sampling gun barrel 102 through the second through slot 2034, and the outer sleeve ring block 2032 is sleeved on the outside of the inner sleeve ring block 2022, the outer horn rubber block 2031 is attached to one end face of the inner horn rubber block 2021, and the snap-fit folded edge 2033 is attached to the other end face of the inner horn rubber block 2021, which is used to achieve wrapping and limiting of the inner horn rubber block 2021 and the inner sleeve ring block 2022.

[0025] In this embodiment: It should be additionally explained that the smoke sampling gun 1 and the external detection host are connected via a hose to transport the smoke. The detection principle of the smoke by the external detection host is the existing technology and has nothing to do with the improvement of this solution. Therefore, it is not drawn or elaborated.

[0026] When the smoke sampling gun 1 is used, its operation is as follows:

[0027] The first blocking piece 202 can be installed on the outside of the sampling gun barrel 102 first, and the inner horn rubber block 2021 and the inner sleeve ring block 2022 can be pried apart through the first through slot 2023. The slot gap of the inner sleeve ring block 2022 will eventually be larger than the outer diameter of the sampling gun barrel 102. At this time, the inner sleeve ring block 2022 can be sleeved on the sampling gun barrel 102 and located between the two limiting ring blocks 201 (it should be noted that the installation position of the first blocking piece 202 can be determined according to the depth to which the sampling gun barrel 102 needs to be inserted into the flue). Then, the inner horn rubber block 2021 and the inner sleeve ring block 2022 are released from being pried apart. The inner horn rubber block 2021 and the inner sleeve ring block 2022 will be reset to their initial state under the action of their own elastic force, and the inner sleeve ring block 2022 will be completely sleeved on the outside of the sampling gun barrel 102, thereby completing the installation of the first blocking piece 202.

[0028] After that, the second sealing piece 203 is installed on the outside of the sampling gun barrel 102. At this time, the first sealing piece 202 is pushed first to make the inner sleeve ring block 2022 fit into an inner sleeve ring block 2022 near the end of the sampling gun barrel 102, and then the outer horn rubber block 2031 and the outer sleeve ring block 2032 are pried apart, and the outer sleeve ring block 2032 is sleeved on the inner sleeve ring block 2022 and the outside of the sampling gun barrel 102. Then, the outer horn rubber block 2031 and the outer sleeve ring block 2032 are released from being pried apart, and finally the snap-fitting folded edge 2033 is pried apart and snapped onto the outside of the outer horn rubber block 2031. In this way, the installation of the second sealing piece 203 is completed. At the same time, the second sealing piece 203 completes the wrapping operation on the first sealing piece 202.

[0029] When the sampling gun barrel 102 is inserted into the flue through the flue inspection port, the first blocking piece 202 finally fits against the outside of the flue, thereby blocking the flue inspection port and preventing smoke leakage from causing discomfort to the inspectors. At the same time, the first blocking piece 202 prevents the sampling gun barrel 102 from moving further, thereby achieving the effect of limiting the insertion depth of the sampling gun barrel 102.

[0030] Please refer to Figures 1 to 4 The inner side of the outer sleeve ring block 2032 is formed with an annular groove that matches the outer wall size of the inner sleeve ring block 2022. The overall length of the combined state of the outer sleeve ring block 2032 and the inner sleeve ring block 2022 matches the spacing between the two adjacent limiting ring blocks 201.

[0031] The concave end surface of the outer speaker rubber block 2031 matches the convex end surface of the inner speaker rubber block 2021 , and the trajectory of the snap-fit folded edge 2033 matches the outer edge of the concave end surface of the inner speaker rubber block 2021 .

[0032] The second through slot 2034 and the first through slot 2023 are staggered along the circumferential direction. The outer wall size of the limiting ring block 201 is smaller than the size of the flue detection port. The large outer diameter size of the inner speaker rubber block 2021 and the outer speaker rubber block 2031 is larger than the size of the flue detection port.

[0033] In this embodiment: when the first sealing member 202 is attached to the outside of the flue, the snap-fitting folding edge 2033 is simultaneously attached to the outside of the flue, and the inner speaker rubber block 2021, the snap-fitting folding edge 2033, and the outer speaker rubber block 2031 will be deformed and attached to the outer wall of the flue under the extrusion force of the inspector. The snap-fitting folding edge 2033 can realize the wrapping limit of the inner speaker rubber block 2021, and can avoid the inner speaker rubber block 2021 from opening along the first through slot 2023. At the same time, the outer speaker rubber block 2031 can seal the first through slot 2023 to ensure a good sealing effect.

[0034] In addition, the structural setting of the first through slot 2023 and the second through slot 2034 makes it easy to disassemble and assemble the first blocking member 202 and the second blocking member 203. While facilitating daily independent storage, it is also easy to adjust the installation position to meet the smoke detection needs of different pipelines.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
