Description

Technical Field

[0001] This utility model relates to the field of flue gas detection technology, and in particular to a portable flue gas sampling and detection bracket. Background Technology

[0002] Flue gas sampling and testing is a crucial technical means in environmental monitoring and industrial process control. It aims to obtain accurate data on flue gas composition through scientific methods, providing a basis for pollution control, equipment optimization, and regulatory compliance. The testing process typically includes sampling point layout, sample collection, pretreatment, and analytical testing. Technicians rationally set sampling points based on the flue structure, flue gas flow direction, and pollutant distribution characteristics to ensure the representativeness and accuracy of the samples. During sampling, isokinetic sampling or predicted flow rate methods are used, employing specialized sampling guns and devices such as filter cartridges and absorption bottles to effectively capture target pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides. After pretreatment such as drying and filtration, the collected samples are rapidly analyzed using advanced analytical techniques such as infrared spectroscopy, chemical titration, or online monitoring instruments to determine the concentration of each pollutant.

[0003] Flue gas detection requires a fixed support. Existing fixed supports usually concentrate the weight of the entire device at the top of the flue, and the support point is relatively single. Impacts or air flow can easily cause the detection device to shake, reducing the efficiency of sampling and detection. At the same time, the support cannot be adjusted efficiently, and it cannot fit the outer surface of the flue better, which is not conducive to use.

[0004] To address this issue, a portable flue gas sampling and testing stand is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable flue gas sampling and testing bracket, which aims to improve the problems of existing fixed brackets, which usually require the entire weight of the device to be concentrated at the top of the flue, and the single support point makes the testing device prone to shaking due to collisions or airflow, resulting in reduced sampling and testing efficiency. At the same time, the bracket cannot be efficiently adjusted, and it cannot fit the outer surface of the flue better, which is not conducive to use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable flue gas sampling and testing bracket includes: a flue, a crossbar at the top of the flue, a clamping mechanism at the bottom of the crossbar near the flue, the clamping mechanism including a U-shaped plate, the U-shaped plate being movably connected to the surface of the crossbar via a pivot pin, a first screw being threadedly connected to the inside of the U-shaped plate, a retaining plate being movably connected to the end of the first screw near the flue via a bearing seat, a knob being fixedly connected to the end of the first screw away from the retaining plate, positioning plates being movably connected to both sides of the crossbar via pivot pins, a second screw being disposed within the two positioning plates, a positioning block being fixedly connected to one end of the second screw, a retaining disc being threadedly connected to the surface of the second screw, adjusting rods being movably connected to both sides of the crossbar via bearing seats, the second screws being located inside the adjusting rods, a fitting mechanism being disposed at the bottom of the adjusting rods, and a flue gas detector being disposed at the top of the crossbar.

[0008] Through the above technical solution, the U-shaped plate and the crossbar are movably connected by a pivot pin, allowing for flexible angle adjustment to adapt to different flue sizes. The first screw, in conjunction with the clamping plate, can be securely locked by rotating the knob, making operation convenient and ensuring the stability of the bracket during testing, thus guaranteeing testing accuracy. At the same time, the second screw, positioning block, and clamping plate facilitate precise angle adjustment of the adjusting rod, thereby forming a stable triangular mechanism between the crossbar and the adjusting rod, improving the stability of the testing device. The fitting mechanism efficiently fits onto the surface of the flue, further enhancing the fixing effect.

[0009] As a further description of the above technical solution: both sides of the abutment plate away from the flue are fixedly connected with limit rods, the limit rods penetrate the U-shaped plate, and the limit rods are used in conjunction with the U-shaped plate.

[0010] The above technical solution, through the setting of the limiting rod, facilitates efficient limiting of the clamping plate, thereby enabling the clamping plate to stably clamp the flue and improving the efficiency of fixing the detection bracket.

[0011] As a further description of the above technical solution: the side of the clamping plate and the U-shaped plate that contacts the flue is fixedly connected with a rubber pad, and the thickness of the rubber pad is three millimeters.

[0012] The above technical solution, through the setting of rubber pads, facilitates the increase of friction between the detection bracket and the flue, thereby further improving the stability of the bracket fixation and making it easier for users to use.

[0013] As a further description of the above technical solution: the bonding mechanism includes a horizontal rod, which is movably connected to the bottom of the adjusting rod via a tightening device, and both ends of the horizontal rod are movably connected to a rotating plate via a tightening device.

[0014] The above technical solution, through the setting of the rotating plate, facilitates the angle adjustment of the bonding plate, thereby enabling the bonding plate to be efficiently bonded to the flue, making it convenient for users.

[0015] As a further description of the above technical solution: both outer sides of the two rotating plates are movably connected to a bonding plate via a tightening device.

[0016] The above technical solution effectively increases the contact area between the bracket and the flue by using the bonding plate, forming a stable triangular structure and making the bracket more secure.

[0017] As a further description of the above technical solution: a support rod is fixedly installed on the top of the crossbar to the bracket by bolts, and one end of the support rod that clamps the flue is fixedly connected to the flue gas detector.

[0018] The above technical solution uses bolts and a mounting bracket to fix the support rod, which facilitates the fixation of the flue gas detector and makes it easier for users to operate.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the U-shaped plate contacts the flue, and the first screw is rotated by a knob. This rotation causes the first screw to move the clamping plate through the limiting rod, clamping the flue and simultaneously attaching the fitting plate to the outer surface of the flue. The angle is fixed by a tightening device. Finally, the positioning block is fixed, and the clamping plate is rotated, causing the clamping plate to move along the second screw to clamp and fix the positioning plate and its internal adjusting rod. This ensures that the flue gas detection bracket is firmly fixed on the top of the flue, allowing for efficient detection by a flue gas detector.

[0021] 2. In this utility model, the rotating plate facilitates the angle adjustment of the bonding plate, thereby enabling the bonding plate to be efficiently bonded to the flue. The support rod is fixed by bolts and a bracket, which facilitates the fixation of the flue gas detector. Attached Figure Description

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.

[0029] Reference Figure 1-4 This utility model provides an embodiment of a portable flue gas sampling and testing bracket, comprising: a flue 1, a crossbar 2 at the top of the flue 1, and a clamping mechanism 3 at the bottom of the crossbar 2 near the flue 1. The clamping mechanism 3 includes a U-shaped plate 31, which is movably connected to the surface of the crossbar 2 via a pin. A first screw 32 is threadedly connected to the inside of the U-shaped plate 31. A retaining plate 33 is movably connected to the end of the first screw 32 near the flue 1 via a bearing seat. A knob 34 is fixedly connected to the end of the first screw 32 away from the retaining plate 33. Positioning plates 35 are movably connected to both sides of the crossbar 2 via pins. A second screw 36 is disposed within the two positioning plates 35. A positioning block 37 is fixedly connected to one end of the second screw 36. A retaining plate 38 is threadedly connected to the surface of the second screw 36. The crossbar 2 is connected to the other side via a pin. The support is movably connected to an adjusting rod 39, and a second screw 36 is located inside the adjusting rod 39. A fitting mechanism 4 is provided at the bottom of the adjusting rod 39, and a flue gas detector 5 is provided at the top of the crossbar 2. The U-shaped plate 31 is movably connected to the crossbar 2 through a pivot pin, which can flexibly adjust the angle to adapt to different flue duct 1 sizes. The first screw 32, in conjunction with the clamping plate 33, can be firmly locked by rotating the knob 34, which is convenient to operate and ensures that the support is stable and does not shake during the detection process, thus ensuring detection accuracy. At the same time, the setting of the second screw 36, the positioning block 37, and the clamping plate 38 facilitates precise angle adjustment of the adjusting rod 39, thereby forming a stable triangular mechanism between the crossbar 2 and the adjusting rod 39, which improves the stability of the detection device. The fitting mechanism 4 efficiently fits onto the surface of the flue duct 1, thereby further improving the fixing effect.

[0030] Reference Figure 1-4Limiting rods 310 are fixedly connected to both sides of the clamping plate 33 away from the flue 1. The limiting rods 310 penetrate the U-shaped plate 31 and are used in conjunction with the U-shaped plate 31. The setting of the limiting rods 310 facilitates efficient limiting of the clamping plate 33, so that the clamping plate 33 can stably clamp the flue 1, thereby improving the efficiency of fixing the detection bracket. Rubber pads 311 are fixedly connected to the side of the clamping plate 33 and the U-shaped plate 31 that contacts the flue 1. The rubber pads 311 are three millimeters thick. The setting of the rubber pads 311 facilitates the increase of friction between the detection bracket and the flue 1, thereby further improving the stability of the bracket fixing.

[0031] Reference Figure 1-4 The bonding mechanism 4 includes a horizontal rod 41, which is movably connected to the bottom of the adjusting rod 39 via a tightening device. Both ends of the horizontal rod 41 are movably connected to rotating plates 42 via tightening devices. The rotating plates 42 facilitate the angle adjustment of the bonding plate 43, thereby enabling the bonding plate 43 to bond efficiently with the flue 1. The outer sides of the two rotating plates 42 are movably connected to the bonding plate 43 via tightening devices. The bonding plate 43 effectively increases the contact area between the support and the flue 1, forming a stable triangular structure, which makes the support more secure. The top of the horizontal rod 2 is fixedly installed with a support rod 44 via bolts and a clamp. One end of the support rod 44 clamps the flue 1 and is fixedly connected to the flue gas detector 5.

[0032] Working principle: By bringing the U-shaped plate 31 into contact with the flue 1, and simultaneously rotating the first screw 32 by the knob 34, the first screw 32 rotates, causing the clamping plate 33 to move through the limiting rod 310 to clamp the flue 1. At the same time, the fitting plate 43 is fitted to the outer surface of the flue 1, and the angle is fixed by the tightening device. Finally, by fixing the positioning block 37 and rotating the clamping plate 38, the clamping plate 38 moves along the second screw 36 to clamp and fix the positioning plate 35 and its internal adjusting rod 39. Thus, the flue gas detection bracket is firmly fixed on the top of the flue 1, and efficient detection is performed by the flue gas detector 5.
