The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The smoke sampling device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] It should be noted that the driving device 3 described in this embodiment can be a motor, and the driving device 3 can drive the magnetic connection component 5 to rotate and provide driving force for the horizontal driving component 4.

[0024] It can be understood that the magnetic connection component 5 described in this embodiment can be magnetically connected to the driving shaft of the driving device 3, so that the driving device 3 can drive the magnetic connection component 5 to rotate on the fixing base 2.

[0025] In order to clearly explain the above embodiment, in one embodiment of the present invention, as Figure 2 and Figure 4 As shown, the magnetic connection assembly 5 includes: a movable seat 51, a connecting column 52, an elastic member 53 and an electromagnet 54, wherein the movable seat 51 is rotatably arranged on the fixed seat 2, one end of the connecting column 52 is arranged on the movable seat 51, the electromagnet 54 is connected to the other end of the connecting column 52 through the elastic member 53, and the electromagnet 54 is magnetically connected to the driving end of the driving device 3, wherein a limiting hole 55 is provided on the connecting column 52, a limiting column 56 is provided on the electromagnet 54, the limiting column 56 is slidably connected to the limiting hole 55, and the elastic member 53 is sleeved on the limiting column 56. A limiting slider 7 is provided on the movable seat 51, a limiting slot 8 is provided at the lower part of the fixed seat 2, and the limiting slider 7 is slidably connected to the limiting slot 8.

[0026] It can be understood that the limiting groove 8 described in this embodiment can be an annular groove with a T-shaped cross section, the limiting slider 7 can be an annular block with a T-shaped cross section, and the limiting groove 8 has a limiting effect on the limiting slider 7.

[0027] It should be noted that the electromagnet 54 described in this embodiment can be magnetically attracted to the driving shaft of the driving device 3 after being energized and magnetized. After being demagnetized, the electromagnet 54 can be separated from the driving shaft of the driving device 3 by the rebound of the elastic member 53 (for example, a spring). The separated electromagnet 54 reduces the sliding friction between the electromagnet 54 and the driving shaft, and has a long service life.

[0028] In one embodiment of the present invention, Figure 2As shown, the horizontal drive assembly 4 may include: a drive bin 41, a ball screw 42, a ball slider 43, a driving wheel 44 and a driven wheel 45, wherein the drive bin 41 is connected to the magnetic connection assembly 5 through a connecting piece, the ball screw 42 is arranged on the drive bin 41 through a bearing, the ball slider 43 is arranged on the ball screw 42, the end of the ball screw 42 passes through the drive bin 41 and extends to the outside of the drive bin 41, the driven wheel 45 is arranged at the end of the ball screw 42, the driving wheel 44 is arranged at the driving end of the driving device 3, and the driving wheel 44 and the driven wheel 45 are meshed with each other.

[0029] It can be understood that the drive bin 41 described in this embodiment is connected to the movable seat 51 through a connecting piece, the drive device 3 can drive the driven wheel 45 to rotate through the driving wheel 44, the driven wheel 45 drives the ball screw 42 to rotate, and the ball slider 43 can move on the rotating ball screw 42.

[0030] In one embodiment of the present invention, Figure 2 As shown, the smoke sampling assembly 6 includes: a sampler 61, an air pipe 62 and a sampling head 63, wherein the sampler 61 is arranged on the sealed chamber 1, the sampling head 63 is arranged on the horizontal driving assembly 4, and the sampling head 63 is connected to the sampler 61 through the air pipe 62.

[0031] It can be understood that the sampling head 63 described in this embodiment is disposed on the ball slider 43 , and when the ball slider 43 moves along the axis of the ball screw 42 , the sampling head 63 can be driven to move.

[0032] Specifically, when sampling the flue, the relevant personnel can insert the present invention into the flue from the flue sampling port and perform sampling work on the inside of the flue through the sampling head 63. When the flue diameter is less than 1 meter, sampling can usually be performed at the center of the flue, but when the flue diameter is greater than 1 meter or the flue has a special shape, it is necessary to arrange multiple sampling points according to the equal area method or the equal distance method for sampling.

[0033] The driving device 3 can drive the driven wheel 45 to rotate through the driving wheel 44, and the driven wheel 45 can drive the ball screw 42 to rotate. The ball slider 43 moving on the rotating ball screw 42 can drive the sampling head 63 to move horizontally to the target position, and when the sampling head 63 needs to be rotated, the electromagnet 54 is energized to generate magnetism, and the electromagnet 54 is magnetically attracted to the driving shaft of the driving device 3 and stretches the elastic member 53. The driving device 3 can drive the magnetic attraction link assembly to rotate on the fixed seat 2. After the sampling head 63 rotates to the target position, the electromagnet 54 loses magnetism and the elastic member 53 rebounds to separate the electromagnet 54 from the driving shaft of the driving device 3. By flexibly adjusting the position of the sampling head 63, multi-point sampling can be performed on the same position to avoid sampling errors caused by uneven local flow fields or uneven distribution of pollutants.

[0034] In one embodiment of the present invention, Figure 2 As shown, it may also include: a guide roller group 9, a plurality of electric telescopic rods 10, and a plurality of abutment rods 11, wherein the guide roller group 9 is arranged in the sealing chamber 1 to support and guide the air pipe 62, and the plurality of electric telescopic rods 10 are arranged in the sealing chamber 1 at equal intervals, and the driving ends of two adjacent electric telescopic rods 10 have opposite telescopic directions, and the abutment rod 11 is arranged at the driving end of the electric telescopic rod 10, and the abutment rod 11 is connected to the air pipe 62 in abutment.

[0035] It is understandable that the electric telescopic rod 10 described in this embodiment can tighten the air pipe 62 by adjusting the vertical movement of the corresponding abutment rod 11. The working position of the abutment rod 11 is determined according to the working position of the sampling head 63 in the flue.

[0036] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, it may also include: a sampling fixture 12, which may include: a plurality of hydraulic telescopic devices 121 and a plurality of abutment plates 122, wherein the plurality of hydraulic telescopic devices 121 correspond to the plurality of abutment plates 122 one by one, wherein the plurality of hydraulic telescopic devices 121 are respectively arranged on the outer wall of the sealing chamber 1, the abutment plates 122 are arranged on the driving end of the hydraulic telescopic devices 121, and the abutment plates 122 are abutted and connected with the inner wall of the flue sampling port. A rubber pad is arranged on the contact surface between the abutment plate 122 and the flue sampling port.

[0037] It is understandable that the hydraulic expansion and contraction device 121 described in this embodiment can push the abutment plate 122 to abut against the inner wall of the flue sampling port, and by fixing the sealed chamber 1 at the flue sampling port, it is avoided that there is a need for manual support, or adjusting a very long support rod for auxiliary support. It should be noted that a counterweight block can be provided in the sealed chamber 1 as needed.

[0038] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, it may also include: a sealing device 13, the sealing device 13 includes: a plurality of airbags 131 and a suction pump 132, wherein the plurality of airbags 131 are arranged outside the sealing chamber 1, the suction pump 132 is arranged on the sealing chamber 1, and the airbags 131 are connected to the suction pump 132 through a connecting pipe 133.

[0039] It can be understood that the suction integrated pump 132 described in this embodiment can inflate the airbag 131, and the inflated airbag 131 can seal the flue sampling port to prevent the smoke in the flue from flowing out of the flue, polluting the environment and possibly affecting the accuracy of the sampling results.

[0040] It should be noted that the motor described in the above embodiment (for example, the drive device 3) is equipped with a brake, which can be used to quickly stop the motor from running. A reduction gearbox is provided on the driving end of the motor, and the driving end of the motor is connected to the input end of the reduction gearbox. The output end of the reduction gearbox constitutes the driving end of the motor, and the speed of the motor output is adjusted by the reduction gearbox.
