DETAILED DESCRIPTION
[0029] Referring to Figure 1 As shown in the utility model provides a technical scheme: a kind of smoke dust sampler, including sampler body 1, the surface of sampler body 1 is connected with collection tube 2, the outside of collection tube 2 is equipped with support structure 3, and the outside of collection tube 2 is equipped with shielding structure 4.
[0030] The specific setting and effect of its support structure 3 and shielding structure 4 are described below.
[0031] Referring to Figures 1-4 As shown, in the embodiment: the support structure 3 comprises a limiting ring 31 fixedly connected to the side wall of the collecting pipe 2, a plurality of support bars 32 are slidingly connected inside the limiting ring 31, the support bars 32 are L-shaped structures, two sliding rods 39 are fixedly connected to the side wall of the limiting ring 31, a pushing ring 36 is slidingly connected to the outer side of the two sliding rods 39, a plurality of inclined frames 37 are uniformly fixedly connected to the side wall of the pushing ring 36, a driving rod 38 is threadedly connected to the inside of the pushing ring 36, and the driving rod 38 is rotatably connected to the inside of the limiting ring 31. Rotating the driving rod 38 will drive the pushing ring 36 to slide on the surface of the sliding rod 39, and the sliding rod 39 is arranged to limit the movement direction of the pushing ring 36. At this time, the inclined surface of the inclined frame 37 on the pushing ring 36 will move relative to the support bar 32, and the simultaneous expansion of the support bar 32 can be realized, thereby realizing the support work of the collecting pipe 2 inside the pipeline.
[0032] The end side of the support bar 32 is glued with a first rubber block 33. By arranging the first rubber block 33, the friction between the side wall of the support bar 32 and the inside of the pipeline is increased. The surface of the support bar 32 is glued with a second rubber block 34. The second rubber block 34 increases the friction between the end side of the support bar 32 and the inside of the pipeline when the end side of the support bar 32 is supported on the inside of the pipeline. The inside of the plurality of support bars 32 is provided with a first elastic ring 35 in an annular structure. Rotating the driving rod 38 in the opposite direction, the pushing ring 36 will exit, and at this time the plurality of support bars 32 will be subjected to the elastic force of the first elastic ring 35 to shrink, thereby facilitating the subsequent removal of the smoke sampler inside the pipeline.
[0033] Referring to Figures 1-3 and Figure 5 As shown, specifically, the shielding structure 4 comprises a circular plate 41 sleeved on the surface of the sampler body 1, a plastic film 42 is glued to the surface of the circular plate 41, and a second elastic ring 43 is fixedly installed at the other end of the plastic film 42. Loosening the second elastic ring 43, the second elastic ring 43 will shrink at the port position of the pipeline, and at this time the plastic film 42 can realize the shielding work of the port position of the pipeline. The surface of the circular plate 41 is glued with a silica gel pad 44. The silica gel pad 44 is arranged to further improve the tightness between the circular plate 41 and the port position of the pipeline when measuring the flue gas inside the large-size pipeline. The inside of the circular plate 41 is glued with a sealing ring 45, and the sealing ring 45 is located outside the collecting pipe 2. The arrangement of the sealing ring 45 improves the sealing effect between the circular plate 41 and the collecting pipe 2.
[0034] When it is necessary to support the collecting pipe 2 of the smoke dust sampler inside the pipeline for measurement work, the side wall of the supporting strip 32 can be inserted into the inside of the pipeline or the supporting strip 32 can be completely inserted into the inside of the pipeline according to the size of the inner diameter of the pipeline. When the inner diameter of the pipeline is relatively small, the side wall of the supporting strip 32 can be inserted into the inside of the pipeline. Conversely, the supporting strip 32 is completely inserted into the inside of the pipeline. After the decision is made, the drive rod 38 is rotated, and the drive rod 38 drives the push ring 36 to slide on the surface of the slide bar 39. The slide bar 39 is arranged to limit the movement direction of the push ring 36. At this time, the inclined surface of the inclined bracket 37 on the push ring 36 will move relative to the supporting strip 32. At this time, the simultaneous expansion of the supporting strip 32 can be realized, thereby realizing the support of the collecting pipe 2 inside the pipeline. By arranging the first rubber block 33, the friction between the side wall of the supporting strip 32 and the inside of the pipeline is increased. The second rubber block 34 increases the friction between the end side of the supporting strip 32 and the inside of the pipeline when the end side of the supporting strip 32 is supported in the inside of the pipeline, thereby improving the stability of supporting the collecting pipe 2 inside the pipeline. The drive rod 38 is rotated in the opposite direction, and the push ring 36 is withdrawn. At this time, the plurality of supporting strips 32 are subjected to the elastic force of the first elastic ring 35 to shrink, thereby facilitating the subsequent removal of the smoke dust sampler inside the pipeline. By arranging the supporting structure 3, the flexible support of the smoke dust sampler inside the pipeline is facilitated, the normal operation of the long-time collection work is facilitated, the operator can effectively collect the flue gas without the support of the hand, and the use performance of the smoke dust sampler is further improved.
[0035] After the smoke dust sampler is supported inside the pipeline, the second elastic ring 43 can be expanded to open the opening of the plastic film 42. After the second elastic ring 43 is sleeved on the port position of the pipeline, the second elastic ring 43 is loosened, and the second elastic ring 43 is contracted on the port position of the pipeline. At this time, the plastic film 42 can realize the covering work of the port position of the pipeline. The arrangement of the sealing ring 45 improves the sealing effect between the circular plate 41 and the collecting pipe 2. The arrangement of the silica gel pad 44 further improves the tightness between the circular plate 41 and the port position of the pipeline when the flue gas measurement work is performed inside the pipeline with a large size. The sealing effect of the covering of the port position of the pipeline is improved. By arranging the shielding structure 4, the flexible shielding work of the port position of the pipeline is facilitated, and the collection efficiency of the flue gas is further improved.
