Description
Technical Field
[0001] This utility model relates to the field of auxiliary support technology, specifically an auxiliary device for air pollution detection. Background Technology
[0002] Air pollutants refer to substances that are released into the atmosphere due to human activities or natural processes and have harmful effects on the environment or humans. As a type of industrial pollution, air pollution is mainly generated by the emission of smoke and exhaust gases from energy, chemical, and recycling factories. In order to effectively detect which type of pollutants are emitted by enterprises and the concentration of the corresponding pollutants, it is necessary to sample, test and analyze the emitted flue gas.
[0003] Existing flue gas sampling methods involve creating a sampling hole outside the flue or furnace wall and inserting a flue gas sampler into the hole. Typically, the hole diameter is larger than the outer diameter of the flue gas sampling gun's barrel. The sampling gun's barrel is effectively fixed to the sampling hole, requiring the sampler to hold the sampler firmly while maintaining its balance and ensuring the sampling port is aligned with the flue gas flow direction. However, the flue gas sampler is quite heavy, placing a significant burden on the sampler and leading to fatigue. Furthermore, uneven force can easily cause the sampling port to not be properly aligned with the flue gas flow direction. Therefore, this paper proposes an auxiliary device for air pollution detection. Utility Model Content

[0011] Two inner clamping plates are provided, symmetrically distributed at the upper and lower ends of the first clamping block and the second clamping block, and the two inner clamping plates are threadedly connected to two screws respectively. By turning the knob, the two screws are rotated, so that the two inner clamping plates are closely fitted to the inside of the flue gas duct measuring port to be tested, thereby realizing the relative positioning of the flue gas sampling gun and the flue gas duct measuring port to be tested.

[0015] As a further embodiment of this utility model: the end face cross-section of the inner clamping piece is a "z" shaped structure, and the top horizontal part of the "z" shaped structure is arc-shaped and the bottom horizontal part is straight. The side ends of the bottom horizontal part of the inner clamping piece are distributed inside the arc-shaped distribution trajectory of the top horizontal part.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-3 In this embodiment of the present invention, an auxiliary device for air pollution detection includes an auxiliary support assembly 1 installed on the outside of the sampling gun barrel of a dust sampling gun 2. The auxiliary support assembly 1 includes a clamping unit, an inner support unit, and a limiting guide unit. The clamping unit is used to realize the installation connection between the inner support unit and the dust sampling gun 2. The inner support unit is used to squeeze and clamp the inner side of the flue gas duct to be tested, thereby realizing the horizontal limitation of the dust sampling gun 2 inside the flue gas duct to be tested. The limiting guide unit is used to provide movement guidance for the expansion or contraction of the inner support unit.
[0025] The clamping unit includes a first clamping block 101, a second clamping block 102, a locking screw hole 103, and a bolt 104;
[0026] The first clamping block 101 and the second clamping block 102 are symmetrically distributed and rotatably connected at one end. The locking screw hole 103 is opened on the side of the first clamping block 101 and the second clamping block 102 away from the rotation point.
[0027] When the first clamping block 101 and the second clamping block 102 are fitted onto the outside of the sampling gun tube of the dust sampling gun 2, the bolts 104 pass through the locking screw holes 103 on the second clamping block 102 and the first clamping block 101 in sequence and are threadedly connected to the locking screw holes 103 to tighten them, so as to realize the fitting and installation of the first clamping block 101 and the second clamping block 102 with the sampling gun tube of the dust sampling gun 2.
[0028] The internal support unit includes a fixed side plate 105, a knob 106, a screw 107, and an internal clamping plate 108;
[0029] Two fixed side plates 105 are provided. The two fixed side plates 105 are symmetrically fixed to the side of the first clamping block 101 away from the second clamping block 102. The knobs 106 are distributed in the middle of the two fixed side plates 105. The screws 107 are symmetrically fixed to the upper and lower ends of the knobs 106 and pass through the two fixed side plates 105 respectively. The screws 107 are rotatably connected to the fixed side plates 105.
[0030] Two inner clamping plates 108 are provided, which are symmetrically distributed at the upper and lower ends of the first clamping block 101 and the second clamping block 102. The two inner clamping plates 108 are threadedly connected to the two screws 107 respectively. The two screws 107 are rotated by the knob 106, so that the two inner clamping plates 108 are closely attached to the inside of the flue gas duct measuring port to be tested, which is used to achieve relative positioning between the flue gas sampling gun 2 and the flue gas duct measuring port to be tested.
[0031] The positioning guide unit includes a fixed guide post 109, which is distributed in the middle of two fixed side plates 105 and passes through the two fixed side plates 105. The fixed guide post 109 is fixedly connected to the fixed side plates 105, and the two inner clamping pieces 108 are slidably sleeved with the fixed guide post 109.
[0032] The fixed guide post 109 and the screw 107 are distributed in parallel. The inner clamping plate 108 has a through hole for the fixed guide post 109 to pass through, and the inner diameter of the through hole matches the outer diameter of the fixed guide post 109.
[0033] The outer wall thread grooves of the two screws 107 have opposite helical directions, and the interior of the two inner clamping plates 108 are respectively provided with threaded holes that match the threaded grooves on the two screws 107.
[0034] In this embodiment: When performing sampling operations using the dust sampling gun 2, the auxiliary support assembly 1 can be assembled with the dust sampling gun 2 first. The first clamping block 101 and the second clamping block 102 are fitted onto the outside of the sampling gun tube of the dust sampling gun 2. Then, the bolt 104 is tightened so that the screw of the bolt 104 enters from the locking screw hole 103 on the second clamping block 102 and passes through the locking screw hole 103 on the first clamping block 101, thereby achieving the connection and fixation of the first clamping block 101 and the second clamping block 102. At the same time, the fitting and limiting of the first clamping block 101, the second clamping block 102 and the sampling gun tube are completed. (It should be noted that the inner wall diameter of the first clamping block 101 and the second clamping block 102 matches the outer wall diameter of the sampling gun tube. There is friction between the first clamping block 101, the second clamping block 102 and the sampling gun tube. At the same time, the sampling gun tube can also move or rotate relative to the first clamping block 101 and the second clamping block 102.)
[0035] Next, insert the front end of the dust sampling gun 2 into the measuring port of the location to be tested. After the inner clamping plate 108 enters the inner side of the measuring port, the knob 106 can be manually rotated. The knob 106 drives the two screws 107 to rotate synchronously, thereby driving the two inner clamping plates 108 to move away from each other. Finally, the two inner clamping plates 108 fit against the inner wall of the measuring port, thereby achieving relative positioning between the dust sampling gun 2 and the measuring port. At this time, the dust sampling gun 2 can maintain a stable horizontal state. At the same time, during the sampling process, the support for the dust sampling gun 2 can be released, which not only reduces the workload of the sampling personnel, but also makes the dust sampling gun 2 more stable than the operation of manually supporting it to maintain balance, which can further improve the sampling accuracy.
[0036] Please refer to this carefully. Figures 1-3 The end face cross-section of the inner clamping piece 108 has a "Z" shaped structure, and the top horizontal part of the "Z" shaped structure is arc-shaped and the bottom horizontal part is straight. The side end of the bottom horizontal part of the inner clamping piece 108 is distributed inside the arc-shaped distribution trajectory of the top horizontal part.
[0037] A limiting block 110 is fixed on the upper surface of the top transverse portion of the inner clamping piece 108. The limiting block 110 is distributed at the end of the fixed guide post 109 away from the screw 107.
[0038] In this embodiment: through the "z"-shaped structure of the inner clamping piece 108, when the two inner clamping pieces 108 are far apart from each other and close to the inner wall of the measuring port, the top horizontal part preferentially fits with the inner wall of the measuring port, and the bottom horizontal part does not interfere with the fit between the top horizontal part and the inner wall of the measuring port, thus ensuring the stability of the clamping and limiting operation.
[0039] When the inner clamping piece 108 enters the measuring port, the limiting block 110 is located outside the measuring port. After the inner clamping piece 108 and the measuring port are clamped, the dust sampling chamber 2 can be pushed to make the sampling port of the dust sampling chamber 2 reach a suitable depth position. The limiting block 110 is in contact with the outer wall of the measuring port to prevent the auxiliary support component 1 from being driven by the dust sampling chamber 2 to move further into the measuring port and causing an impact on the fixed guide post 109.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
