[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] like Figure 1-4 As shown, this embodiment proposes a pipeline gas detection device, including a pipeline 1, a fixed shaft 3 is fixedly connected in the pipeline 1, the fixed shaft 3 is arranged in a vertical direction, the fixed shaft 3 is connected to a driving mechanism, the driving mechanism is connected to a fork 11, and the fork 11 is slidably connected to a sliding rod 12. The driving mechanism is used to drive the fork 11 to rotate.

[0028] The fixed shaft 3 is rotatably connected with an elastic column 6, the elastic column 6 is connected with a detection head 14, and the detection head 14 is connected with an analyzer 4. The upper end of the elastic column 6 is rotatably connected with the fixed shaft 3 through a bearing, and the elastic column 6 can rotate freely around the fixed shaft 3. The elastic column 6 itself has elasticity, so it can bend, and after bending, it can automatically reset.

[0029] A connecting seat 2 is fixedly connected to the outer wall of the pipeline 1, and the analyzer 4 is connected to the connecting seat 2. The analyzer 4 is arranged on the outside of the pipeline 1. The detection head 14 can be electrically connected to the analyzer 4 through a wire. The wire passes through the elastic column 6, the fixed shaft 3 and the pipeline 1 and is connected to the analyzer 4.

[0030] The fixed shaft 3 is provided with a T-shaped slot 7 connected end to end, and a sliding rod 12 is slidably arranged in the T-shaped slot 7 , and one end of the sliding rod 12 is connected to the elastic column 6 through a pull rope 13 .

[0031] The T-slot 7 is annularly arranged on the fixed shaft 3, and the sliding rod 12 can slide freely in the T-slot 7. Under the action of the T-slot 7, the spatial change of the upper end position of the sliding rod 12 can be achieved, thereby driving the elastic column 6 to bend a certain angle through the pull rope 13.

[0032] One end of the elastic column 6 close to the detection head 14 is rotatably connected to the rotating ring 5, one end of the pull rope 13 is connected to the sliding rod 12, and the other end of the pull rope 13 is connected to the rotating ring 5. The rotating ring 5 facilitates the pull rope 13 to pull the elastic column 6 to rotate to prevent jamming.

[0033] In the initial state, the elastic column 6 is set in an inclined direction, so when the sliding rod 12 changes its spatial position along with the shape of the T-slot 7, it can drive the pull rope 13 to move upward or downward, so that under the action of the elastic force of the elastic column 6 itself, the elastic column 6 can bend to different degrees, thereby realizing the airflow detection work at different heights in the pipeline 1.

[0034] The driving mechanism comprises a disc gear 8 , which is sleeved on the fixed shaft 3 , the disc gear 8 is rotationally connected to the fixed shaft 3 , and the disc gear 8 is fixedly connected to the shift fork 11 .

[0035] A fan blade 10 is rotatably arranged in the pipeline 1, and the fan blade 10 is arranged at one end close to the airflow; the fixed shaft 3 is rotatably connected to the transmission shaft 16, one end of the transmission shaft 16 is rotatably connected to the fan blade 10, and the other end of the transmission shaft 16 is rotatably connected to the bevel gear 9, which is meshed with the disc gear 8.

[0036] Under the action of airflow, the fan blades 10 can be driven to rotate. When the fan blades 10 rotate, the bevel gear 9 can be driven to rotate through the transmission shaft 16, and then the disc gear 8 can be driven to rotate. Without the need for an additional power source, the spatial change of the position of the detection head 14 in the pipeline 1 can be achieved.

[0037] The shift fork 11 is provided with an elongated hole 15 . The shift fork 11 and the elongated hole 15 are both arranged in a vertical direction. The sliding rod 12 passes through the elongated hole 15 , and the sliding rod 12 is slidably connected to the elongated hole 15 .

[0038] The width of the elongated hole 15 matches the sliding rod 12, so the sliding rod 12 can only slide along the length of the elongated hole 15. Therefore, when the shift fork 11 rotates, the sliding rod 12 can be driven to rotate at the same time through the elongated hole 15. The length of the elongated hole 15 is long enough, so when the sliding rod 12 slides in the T-slot 7, the sliding rod 12 can slide freely in the vertical direction in the elongated hole 15.

[0039] The present invention also provides a method for using a pipeline gas detection device, which also includes the above-mentioned pipeline gas detection device, including the following steps:

[0040] S1: With the flow of air in the pipe 1, the fan blade 10 is driven to rotate under the action of the air flow, and the fan blade 10 drives the bevel gear 9 to rotate through the transmission shaft 16, and the bevel gear 9 drives the shift fork 11 to rotate through the disc gear 8;

[0041] S2: When the shift fork 11 rotates, under the action of the long hole 15, the shift fork 11 drives the sliding rod 12 to rotate, and the sliding rod 12 drives the elastic column 6 to rotate through the pull rope 13, thereby driving the detection head 14 to rotate;

[0042] S3: As the fork 11 rotates, under the action of the T-slot 7, the sliding rod 12 slides in the T-slot 7, and the sliding rod 12 slides along the long hole 15. Under the action of the elastic column 6, the elastic column 6 drives the height of the detection head 14 in the pipeline 1 to change;

[0043] S4: the detection head 14 transmits corresponding signals to the analyzer 4, and the analyzer 4 displays the airflow components. As the detection head 14 rotates and its height in the pipeline 1 changes continuously, the airflow detection work at different positions in the pipeline 1 is performed.

[0044] It should be noted that when the bevel gear 9 rotates, the sliding rod 12 can be driven to rotate through the fork 11, so that the detection head 14 can be rotated in the pipeline 1. While the detection head 14 rotates, the sliding rod 12 slides in the T-slot 7. Therefore, the sliding rod 12 can drive the elastic column 6 up and down through the pull rope 13, so that the detection head 14 can be moved at a high level in the pipeline 1, and gas detection work can be carried out at different positions in the pipeline 1, which effectively reduces the detection error and improves the detection accuracy.

[0045] In addition, under the action of airflow, the fan blades 10 can be driven to rotate, and the fan blades 10 drive the disc gear 8 to rotate through the bevel gear 9. No additional power source is required, the operation is convenient, the structure is reasonable, and the cost is low, thereby realizing the movement of the detection head in the pipeline.

[0046] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
