Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of flue gas sampling technology, specifically relates to a convenient flue gas sampling gun. BACKGROUND

[0002] Flue gas is the mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex, including water vapor, sulfur dioxide, N2, O2, carbon monoxide, C02 hydrocarbon and nitrogen oxides, etc. The smoke includes ash, coal particles, oil droplets and high-temperature cracking products, etc. Therefore, the pollution of flue gas to the environment is a composite pollution of various poisons. In order to specifically manage the flue gas pollution, it is necessary to sample and test the flue gas in the area, so as to determine the composition of various substances in the flue gas and facilitate the management. At present, the flue gas sampling gun is generally used for sampling flue gas.

[0003] When using the flue gas sampling gun, the platform needs to be lifted to lift the worker and the flue gas sampling gun to the sampling port of the flue gas cylinder. Because the lifting platform is small, the existing fixed equipment supporting the flue gas sampling gun cannot stand the worker after the worker is placed on the lifting platform, so the worker needs to keep the position of the sampling gun until the sampling time is over, which brings a great burden to the worker, and also cannot guarantee the stability of sampling.

[0004] The document with the authorized announcement number CN222212388U discloses a flue gas sampling gun for preventing leakage of the sampling port, comprising a gun barrel, a plurality of supports are rotationally connected in a circular array at one end of the gun barrel, a connecting rod is hinged to one side of each support close to the gun barrel, a connecting ring is slidingly connected to the side surface of the gun barrel, one end of each connecting rod close to the connecting ring is hinged to the connecting ring, and a sealing film with elastic deformation is collectively bonded to one side of each support away from the gun barrel.

[0005] Although the device improves the sealing effect of the sampling port of the flue gas cylinder, the torsional spring and other structures cannot fix the heavy flue gas sampling gun at the sampling port, so additional fixing equipment is still needed to support the flue gas sampling gun. Therefore, there is an urgent need for a convenient flue gas sampling gun that can ensure the flue gas sealing of the sampling port and avoid manual lifting of the flue gas sampling gun.

[0035] In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance

[0036] In the description of the utility model, it is also necessary to point out that, unless otherwise explicitly specified and limited, the terms "arrangement", "connection" and the like should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integrally connected: can be mechanical connection, or electrical connection: can be direct connection, or indirect connection through intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0037] The embodiment provides a convenient flue gas sampling gun, as shown in the accompanying Figure 1 Figure Figure 5 As shown, it comprises a sampling gun a and a fixing member arranged on the sampling gun a, the fixing member comprises:

[0038] A fixing pipe 1 is sleeved on the outer side of the sampling gun a;

[0039] Two connecting bands 2 are symmetrically installed on the two sides of the fixing pipe 1, and the end portions of the two connecting bands 2 away from the fixing pipe 1 are detachably connected;

[0040] A fixing cylinder 3 is installed on the end portion of the fixing pipe 1 close to the flue gas cylinder b;

[0041] A sealing cylinder 4 is connected with the outer circumferential side of the fixing cylinder 3 at one end and abuts against the surface of the flue gas cylinder b at the other end.

[0042] Wherein, the sampling gun a and the flue b are well known to those skilled in the art, so this embodiment will not be described. Because the sampling gun a has bulging ends, in order to ensure that the fixing member can be quickly and detachably connected with the sampling gun a, the fixing tube 1 comprises two oppositely arranged half cylinders 11, at least two connecting ears 12 arranged on the end of the half cylinder 11 away from the flue b, and connecting bolts 13 connecting the connecting ears 12 on the two half cylinders 11; the fixing cylinder 3 is sleeved on the outside of the end of the two half cylinders 11 close to the flue b.

[0043] Specifically, the two connecting ears on the same half cylinder 11 are symmetrically distributed, the connecting ears 12 on the two half cylinders 11 are butted and connected by the connecting bolts 13 to complete the close connection of the end of the two half cylinders 11; the ends of the two half cylinders 11 away from the connecting ears 12 are connected by the fixing cylinder 3 sleeved on the outside.

[0044] Further, the fixing tube 1 further comprises arc-shaped grooves 14 arranged on the outer circumferential side of the end of the half cylinder 11 away from the connecting ears 12 and matched with the fixing cylinder 3. Wherein, the two arc-shaped grooves 14 are butted and form a ring-shaped groove matched with the fixing cylinder 3, so that part of the fixing cylinder 3 is embedded in the ring-shaped groove, thereby reinforcing the fixing cylinder 3.

[0045] Further, the fixing tube 1 further comprises a sealing layer 15 arranged on the inner wall of the half cylinder 11. Wherein, the sealing layer 15 can be made of materials such as rubber to cover the inner wall of the half cylinder 11, so that the two half cylinders 11 can tightly clamp the sampling gun a and achieve a sealing effect.

[0046] In this embodiment, the outer circumferential side of the fixing cylinder 3 is provided with external threads 31, and the inner cylinder wall of the sealing cylinder 4 is provided with internal threads 41 matched with the external threads 31. Wherein, through the screw connection between the sealing cylinder 4 and the fixing cylinder 3, the position of the sealing cylinder 4 on the fixing cylinder 3 can be adjusted, so as to adjust the installation position of the sampling gun a outside the flue b (after the fixing position of the fixing tube 1 on the sampling gun a is determined, the position of the sealing cylinder 4 on the fixing cylinder 3 can be determined, the distance between the end of the fixing tube 1 away from the flue b and the flue b, so as to determine the length of the sampling gun a in the flue b). It is worth noting that no matter how the sealing cylinder 4 is adjusted, the end of the fixing cylinder 3 should not exceed the end of the sealing cylinder 4.

[0047] In this embodiment, the cross section of the sealing cylinder 4 is isosceles trapezoidal, and the shorter end of the isosceles trapezoid is connected with the outer circumferential side of the fixing cylinder 3. The advantage of this arrangement is that the coverage area of the sealing cylinder 4 can be increased as much as possible, so that the sealing cylinder 4 can adapt to sampling ports of different sizes and shapes.

[0048] In the embodiment, the end of the sealing cylinder 4 abutting against the surface of the flue cylinder b is formed with an arc surface 42 which is in close contact with the surface of the flue cylinder b. The material of the arc surface 42 can be a high polymer material such as deformable plastic, or a material such as wood or metal which is formed in the form of a thin plate to have a rigid deformation function, so as to ensure that the arc surface 42 can be as close as possible to the outer wall of the flue cylinder b.

[0049] In the embodiment, the surface of the arc surface 42 is provided with an anti-skid layer 43. The anti-skid layer 43 can be made of a material such as rubber and formed in the form of a block-shaped thin layer which is distributed at intervals on the surface of the arc surface 42, so as to further enhance the close contact of the arc surface 42 with the outer wall of the flue cylinder b.

[0050] In the embodiment, the surface of the arc surface 42 is provided with an embedded groove 44 which is matched with the connecting belt 2. It is worth noting that one end of the connecting belt 2 is fixed to the outer wall of the fixed tube 1, and the other end (free end) is in close contact with the outer wall of the fixed tube 1 and extends to the end of the fixed tube 1. After the fixed cylinder 3 is connected to the fixed tube 1, part of the connecting belt 2 is fixed between the fixed cylinder 3 and the fixed tube 1, and the free end of the connecting belt 2 continues to extend. After the sealing cylinder 4 is installed, the connecting belt 2 extends out of the sealing cylinder 4 and winds around the outer wall of the flue cylinder b. The free ends of the two connecting belts 2 are connected to each other, so as to fix the fixed tube 1 to the flue cylinder b. Therefore, the sampling gun a is also fixed to the flue cylinder b, which replaces the manual lifting of the sampling gun a for sampling.

[0051] As some preferred embodiments, the fixed cylinder 3 is provided with a mounting groove 32 near the end of the flue cylinder b, a fixed rod 33 which is embedded into the mounting groove 32 at one end and extends into the flue cylinder b at the other end, a connecting plate 34 which is arranged at the end of the fixed rod 33 located in the flue cylinder b, and a tension spring 35 which is arranged in the mounting groove 32 and connected with the fixed rod 33. The above structure takes the mounting groove 32 as an example, and the number of the mounting grooves 32 is at least two. In addition, the length of the fixed rod 33 needs to be greater than the thickness of the cylinder wall of the flue cylinder b, and the maximum distance between the two connecting plates 34 needs to be greater than the caliber of the sampling port. When the fixed tube 1 is installed, the connecting plate 34 at the end can enter the flue cylinder b through the sampling port by compressing the fixed rod 33. When the compression of the fixed rod 33 is released, the connecting plate 34 remains in a parallel posture with the inner wall of the flue cylinder b to form a hook portion, so as to ensure that the connecting plate 34 cannot be separated from the flue cylinder b. After the fixed belt 2 is fixed, the connecting plate 34 is in abutment with the inner wall of the flue cylinder b due to the tension of the tension spring 35 on the fixed rod 33, and cooperates with the sealing cylinder 4 inside and outside, so as to further enhance the fixing effect of the fixed member, thereby ensuring the stability of the sampling gun a.

[0052] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
