[0003] When the flue gas analyzer needs to detect the flue gas flow rate in the flue, a Pitot tube is used in conjunction with the flue gas analyzer. The input end of the Pitot tube is extended into the flue, so that the flue gas enters the flue gas analyzer through the Pitot tube, and the flue gas analyzer detects the flow rate of the flue gas. The flue gas analyzer is also connected to a sampler, and the sampling tube of the sampler is extended into the flue, so that the flue gas enters the flue gas analyzer during the flow in the flue, and the flue gas analyzer is used to analyze and detect the specific components in the flue. When using the flue gas analyzer to analyze and detect the flue, multiple sampling points are usually set on the flue. By moving the flue gas analyzer at multiple sampling points, the flue gas analyzer performs detection in sequence between the multiple sampling points, thereby performing a more detailed analysis and detection of the flow rate and composition of the flue gas.

DETAILED DESCRIPTION The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, this embodiment proposes a freely configurable flue gas analyzer, including a flue gas analyzer body 1, a sampling tube 2 and a pitot tube 3. The flue gas analyzer body 1 is provided with a sampling port 4 and two air inlets 5. The pitot tube 3 is connected with two air delivery pipes 6. The flue gas analyzer body 1 is a prior art device for detecting and analyzing the flow rate and components of flue gas in the prior art, and is a prior art device well known to those skilled in the art. When it is necessary to detect the flow rate of flue gas in the flue, it is necessary to extend the air inlet end of the pitot tube 3 into the flue so that The air inlet end corresponds to the flow direction of the flue gas in the flue, and then the two air pipes 6 are connected to the air inlet 5 set on the flue gas analyzer body 1. The flow rate of the flue gas is detected through the flue gas analyzer body 1. When it is necessary to sample and detect the components of the flue gas, the sampling tube 2 is first extended into the flue, so that the flue gas is moved out of the flue through the sampling tube 2, and then the large particles of impurities in the flue are filtered, and then the flue gas is passed through the exhaust pipe 9 into the sampling port 4, and then the components in the flue are analyzed and detected through the flue gas analyzer body 1.

A fixing block is slidably connected to the fixing member 48 through a plug plate 49. When the flue gas analyzer body 1 needs to be fixed between the two support seats 45, First, place the flue gas analyzer body 1 on two support seats 45, and synchronously rotate the movable screws 47 on the two support seats 45 so that the movable screws 47 push the clamping plates 46 to slide on the support seats 45, so that the two clamping plates 46 clamp the two sides of the flue gas analyzer body 1, and make the fixed block contact with the top of the flue gas analyzer body 1. Because the fixed block is vertically connected to the fixing member 48 through the plug plate 49, when the fixed block contacts the top of the flue gas analyzer body 1, the problem of the flue gas analyzer body 1 tipping over can be effectively avoided.

[0025] like Figures 1 to 4 , Figure 7 and Figure 8 As shown, the mobile traction assembly 700 includes a rotating frame 50, a winding cylinder 52 and a traction rope 54. The rotating frame 50 is fixedly connected to the top of the installation box 7 through a bracket. The bottom of the rotating frame 50 is fixedly connected to a fixed slot body, and a plurality of guide wheels 51 are rotatably connected to the fixed slot body. The winding cylinder 52 is rotatably connected in the rotating frame 50. A second drive motor 53 is arranged on the rotating frame 50, and the output end of the second drive motor 53 is fixedly connected to the winding cylinder 52. The traction rope 54 is wound around the winding cylinder 52, and the traction rope 54 is arranged to transmit the traction rope. One end of the traction rope 54 is fixedly connected to the fixing part 48 between the multiple guide wheels 51. When multiple installation boxes 7 are arranged on the flue, a mobile traction assembly 700 can be arranged only on the top of the highest installation box 7. The flue gas analyzer body 1 is driven to move between the multiple installation boxes 7 by the mobile traction assembly 700. The second drive motor 53 is started to drive the winding cylinder 52 to rotate in the rotating frame 50, so that the traction rope 54 pulls the fixing part 48, the sliding groove body 42 and the flue gas analyzer body 1, so that the flue gas analyzer body 1 moves longitudinally.

[0026] Working principle of the freely configurable flue gas analyzer: A plurality of sampling points are arranged on the flue, and an upper mounting box 7 is connected to each sampling point, and various components are installed inside the mounting box 7, and then a mobile traction assembly 700 is arranged on the mounting box 7 located at the uppermost side, so that the mobile traction assembly 700 can drive the flue gas analyzer body 1 to move on the flue; First, the flue gas analyzer body 1 is placed on the two support seats 45, and the moving screws 47 on the two support seats 45 are synchronously rotated so that the moving screws 47 push the clamping plates 46 to slide on the support seats 45, so that the two clamping plates 46 clamp the two sides of the flue gas analyzer body 1, and the fixed block contacts the top of the flue gas analyzer body 1, and the second drive motor 53 is started to drive the winding cylinder 52 to rotate in the rotating frame 50, so that the traction rope 54 pulls the fixing part 48, the sliding groove body 42 and the flue gas analyzer body 1, so that the flue gas analyzer body 1 is moved forward. The flue gas analyzer body 1 is moved longitudinally from bottom to top to the vicinity of the installation box 7, so that the flue gas analyzer body 1 can detect the flow rate and composition of the flue gas in the flue, and prevent the flue gas analyzer body 1 from colliding with the installation box 7 during the movement, and the third electric cylinder 44 is started to push the sliding seat 43 to slide in the sliding groove 42, so that the sliding seat 43 moves the position of the flue gas analyzer body 1, so that the flue gas analyzer body 1 is prevented from contacting with other installation boxes 7 during the lifting and lowering process driven by the traction rope 54; When the flue gas analyzer body 1 is moved to the corresponding installation box 7, the first electric cylinder 17 and the second electric cylinder 26 are started to drive the plurality of ferrous rings 15 to descend, and when the gas pipe 6 and the exhaust pipe 9 are driven to descend, the ferrous ring 27 and the electromagnetic device 29 are fitted together, and the electromagnetic device 29 is powered to generate magnetism, and then the gas pipe 6 is connected to the air inlet 5 and the exhaust pipe 9 is connected to the sampling tube 2, and the first drive motor 33 is started to drive the transmission screw 31 to rotate, so that the transmission screw 3 1 drives the threaded seat 32 to move horizontally in the moving frame 30, so that the threaded seat 32 drives the double-headed electric cylinder 34 to move horizontally, so that the meshing seat 37 moves to the position corresponding to the sliding member 36, and the double-headed electric cylinder 34 is started to drive the meshing seat 37 to move, so that the meshing seat 37 is meshed with the corresponding sliding member 36. In the process that the transmission screw 31 continues to drive the threaded seat 32 to move, the sliding member 36 drives the conveying box 18 to drive the pitot tube 3 to move horizontally, so as to facilitate the sampling tube 2 or the pitot tube 3 to be moved into the flue; The air inlet end of the Pitot tube 3 is extended into the flue so that the air inlet end corresponds to the flow direction of the flue gas in the flue, and then the two gas pipes 6 are connected to the air inlet 5 set on the flue gas analyzer body 1. The flow rate of the flue gas is detected through the flue gas analyzer body 1. When it is necessary to sample and detect the components of the flue gas, first extend the sampling tube 2 into the flue, so that the flue gas is moved out of the flue through the sampling tube 2, and then after filtering the large particles of impurities in the flue, the flue gas is allowed to enter the sampling port 4 through the exhaust pipe 9, and then the components in the flue are analyzed and detected through the flue gas analyzer body 1.
