In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0038] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an online carbon emission detection device of the utility model in conjunction with the accompanying drawings.

[0039] like Figure 1-Figure 4 As shown, an online carbon emission detection device of the utility model comprises a metal tube 2 with one end that can be inserted into the flue, and a first sampling tube 4 and a second sampling tube 41 coaxially arranged inside the metal tube 2 for sampling the flue gas inside the flue, and one end of the second sampling tube 41 is inserted into the first sampling tube 4 so that it can be telescopically moved to facilitate adaptive adjustment. A detection component 3 for detecting flue gas is provided at the end of the metal tube 2, and the flue gas discharged from the flue is detected by the detection component 3. At the same time, a heating wire 31 is provided on the outer peripheral surface of the detection component 3 to heat the flue gas to prevent the generation of water vapor.

[0040] The outer surface of the detection component 3 is covered with a box-type housing 1 for protection, so as to prevent the detection component 3 inside the box-type housing 1 from being directly exposed to the outdoors.

[0041] like Figure 5-Figure 8 As shown, the inner ring wall of the first sampling tube 4 is provided with slide grooves 42 opposite to each other with the center of the circle as the axis, and the end openings of the second sampling tube 41 located inside the first sampling tube 4 are respectively provided with sliders 414 that can move inside the slide groove 42, so the second sampling tube 41 can be limited and telescopically moved by the sliders 414 and the slide groove 42.

[0042] A first bracket 43 is provided inside the first sampling tube 4 away from the sampling port at one end of the second sampling tube 41. At the same time, a rotatable threaded rod 44 is coaxially penetrated on one side of the first bracket 43, and one end of the threaded rod 44 extends to the inside of the second sampling tube 41. A crown gear 45 for driving the threaded rod 44 to rotate is fixedly provided at the end of the threaded rod 44 located inside the first sampling tube 4. A gear 22 is meshedly connected to one side of the crown gear 45. A motor 21 for driving the gear 22 to rotate is provided downward at the bottom of the outer peripheral surface of the metal tube 2. Therefore, when the motor 21 is running, the running motor 21 can drive the gear 22 set at the output end, and then the rotation of the gear 22 can rotate the threaded rod 44 together through the crown gear 45.

[0043] The outer surface of the threaded rod 44 located inside the second sampling tube 41 is threadedly connected with a threaded ring 412, and the threaded ring 412 is fixed through its outer circumferential surface to the second bracket 411 at the opening of the second sampling tube 41. After the threaded ring 412 is limited by the second bracket 411, the second sampling tube 41 can be telescopically moved with the rotation of the threaded rod 44. And one end of the second sampling tube 41 is inserted into the first sampling tube 4, so the inner wall of the first sampling tube 4 can be cleaned while the second sampling tube 41 moves, and then with backblowing, the fallen particles can be backblown and cleaned.

[0044] The end opening of the second sampling tube 41 is provided with an inclined portion 413 of an inclined structure to facilitate the discharge of particles during back-blowing.

[0045] A third bracket 46 is provided on the outer circumference of the end of the threaded rod 44 located inside the second sampling tube 41, and a rotating ring 47 having a diameter matching the inner wall of the second sampling tube 41 can be fixed by the third bracket 46. At the same time, the rotating ring 47 can wipe and clean the particles on the inner wall of the second sampling tube 41. Therefore, after the threaded rod 44 is rotated by the motor 21, the rotating ring 47 provided at the end of the threaded rod 44 can be driven to rotate together with the rotation of the threaded rod 44. Therefore, when the rotating ring 47 rotates and the second sampling tube 41 is extended and moved, the second sampling tube 41 can be wiped and cleaned by the rotating ring 47.

[0046] A dustproof ring 48 is extended to one side on the surface of the rotating ring 47 near the opening of the second sampling tube 41. Therefore, when the rotating ring 47 moves toward the opening of the second sampling tube 41, the particles on the top of the inner ring wall of the second sampling tube 41 are dropped by the pushing shovel of the rotating ring 47 and can be collected by the dustproof ring 48. At the same time, as the dustproof ring 48 rotates, the particles on the top can be rotated to the bottom, which facilitates the pushing shovel of the rotating ring 47 to move and clean, and prevents the particles on the top from falling during cleaning.

[0047] like Figure 9-10 As shown, a hollow rotating groove 471 is provided inside the rotating ring 47, and protrusions 472 are arranged at intervals on the bottom of the rotating groove 471 with the center of the circle as the axis, and a ball 473 for falling and hitting is arranged inside the rotating groove 471. Therefore, when the rotating ring 47 rotates, the ball 473 inside the rotating ring 47 can roll continuously, and because the protrusions 472 are arranged at intervals inside the rotating ring 47, the ball 473 can achieve a vibration effect when rolling, so as to facilitate the cleaning of particles on the surface of the dustproof ring 48.

[0048] Working principle of an online carbon emission detection device: After the threaded rod 44 is rotated by the motor 21, the rotation of the threaded rod 44 can drive the rotating ring 47 set at its end to rotate together. Therefore, while the rotating ring 47 rotates, and accompanied by the telescopic movement of the second sampling tube 41, the second sampling tube 41 can be wiped and cleaned by the rotating ring 47. At the same time, as the rotating ring 47 rotates, the ball 473 inside the rotating ring 47 can continuously roll. Since the rotating ring 47 is provided with spaced protrusions 472 inside, the ball 473 can achieve a vibration effect when rolling, so as to facilitate the cleaning effect of particulate matter on the surface of the dust ring 48.

[0049] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
