[0023] To clearly illustrate the solutions of the present invention, preferred embodiments are provided below and described in detail with reference to the accompanying drawings. The following description is merely illustrative in nature and is not intended to limit the application or use of the present disclosure. It should be understood that throughout the drawings, corresponding reference numerals indicate identical or corresponding parts and features.

[0024] Figure 1 It is a structural diagram of a pipe diverter according to an embodiment of the present utility model. As shown in the figure, the pipe diverter of the embodiment may include a worm drive assembly 10, an S-type tube 20, a first panel module 30, a second panel module 40 and a housing 50. The S-type tube 20 is S-shaped as a whole and is arranged between the first panel module 30 and the second panel module 40. The worm drive assembly 10 is arranged on the first panel module 30 and is connected to one end of the S-type tube 20. The two ends of the housing 50 are respectively connected to the first panel module 30 and the second panel module 40, and the three basically enclose a space, and the worm drive assembly 10 and the S-type tube 20 are enclosed in this space. Figure 2-5 The specific structure of the pipeline diverter is further described in detail.

[0025] Figure 2 Schematic diagram of the structure of the worm drive assembly of the pipeline diverter according to the embodiment of the present utility model; Figure 3 This is a partial structural diagram of a pipeline diverter according to an embodiment of the present utility model from one perspective; Figure 41 is a partial structural diagram of a pipeline diverter according to an embodiment of the present utility model from another perspective; Figure 5 It is a partially enlarged structural schematic diagram of a pipeline diverter according to an implementation scheme of the utility model.

[0026] As shown in the figure, the worm drive assembly 10 includes a worm 11, a worm gear 12, a motor 13, a coupling 14, and an electromagnetic brake 15. The worm drive assembly 10 can be fixed to the first panel 31 of the first panel module 30 using bolts or other means. The worm gear 12 of the worm drive assembly 10 is mounted on the first end 21 of the S-shaped tube 20. The motor 13 drives the worm 11 through the coupling 14, thereby driving the worm gear 12, which in turn drives the first end 21 of the S-shaped tube 20. The motor 13 can rotate clockwise or counterclockwise, thereby driving the first end 21 of the S-shaped tube 20 to rotate clockwise or counterclockwise. The electromagnetic brake 15 precisely controls the rotation angle of the worm 11 through electromagnetic force.

[0027] The first panel module 30 includes a first panel 31 , on which a circular channel is formed. A single pipe joint 32 is fixed to one side of the first panel 31 and communicates with the circular channel. The other side of the first panel 31 communicates with the port of the first end 21 of the S-shaped tube 20 .

[0028] More specifically, the worm gear 12 can be selected from a conventional turbine, for example, a worm gear having a conventional structure with an inner and outer ring, with a rolling seal between the inner and outer rings. The outer ring is formed with a gear that mates with the gear on the worm 11. The first end 21 of the S-shaped tube 20 is fixed to the outer ring, and the inner ring is fixed to the first panel 31. As a result, the first end of the S-shaped tube 20 is sealedly aligned with the circular channel on the first panel 31 and communicates with the single pipe joint 32. During operation, the clockwise or counterclockwise rotation of the motor 13 drives the worm 11, the outer ring of the worm gear 12, and the S-shaped tube 20 to rotate clockwise or counterclockwise.

[0029] The second panel module 40 may include a second panel 41, a rotary joint 42, a bolt 43, a position sensor 44, a reflector 45, and a stop block 46. Figure 4 and 5As shown, the second panel 41 is formed with three circular channels. A rotary joint 42 is sleeved onto the second end 22 of the S-shaped tube 20, and one end of the rotary joint 42 is rotatably fixed to the second panel 41 via a bolt 43. A reflector 45 (e.g., a metal plate) is disposed on the rotary joint 42. Three position sensors 44 are disposed on the three circular channels to sense whether the second end 22 of the S-shaped tube 20 is aligned with the circular channels. When the second end 22 is aligned with the circular channels, the position sensors 44 detect the presence of the reflectors 45, thereby determining that the second end 22 is aligned with the circular channels. The worm drive assembly 10 can then stop operating / rotating based on the sensing signals from the position sensors 44. Two stoppers 46, e.g., polyurethane blocks, are disposed at the lower end of the second panel 41. When the second end 22 rotates clockwise or counterclockwise until it is aligned with the two lower circular channels, the stoppers 46 help limit further rotation of the S-shaped tube 20. Specifically, the rotary joint 42 contacts the stoppers 46, preventing further downward movement. Additionally, to achieve sealing, a sealing gasket may be provided at the circular channel or the rotary joint to enhance the sealing during alignment.

[0030] During operation, driven by the worm 11 and the worm wheel 12, the first end 21 of the S-shaped tube 20 rotates, driving the second end 22 to rotate clockwise or counterclockwise around the bolt 43, so that the port of the second end can switch between the three circular channels of the second panel 41, and are respectively sealed and aligned with the three circular channels, and are respectively connected to the three pipe joints 47 fixed on the second panel 41.

[0031] Figure 6 This is a schematic diagram of the structure of a pneumatic transmission and delivery system including a pipeline diverter according to an embodiment of the present invention. As shown in the figure, the pneumatic transmission and delivery system of the embodiment may include the pipeline diverter, a receiving station, a sending station, a fan power unit, a control system, a sample storage and inspection cabinet, and connecting pipes connecting these components. The pipeline diverter's single pipe joint 32 is connected to the fan power unit, while three pipe joints 47 are respectively connected to the receiving station, the sending station, and the sample storage and inspection cabinet. The control system is electrically connected to the pipeline diverter, the receiving station, the sending station, the fan power unit, and the sample storage and inspection cabinet to control the operation of these components. A starting buffer tube is disposed on the pipeline between the pipeline diverter and the fan power unit, and a photoelectric sensor may be provided on the starting buffer tube. When the sample bottle reaches the starting buffer tube through the suction of the fan power unit, the photoelectric sensor senses the situation and sends a signal to the control system, causing the pipeline diverter to begin diverting to the device to which the sample bottle is to be connected. Once the position sensor 44 detects the completion of the diversion, the fan power unit resumes blowing air, moving the sample bottle to the appropriate position.

[0032] In summary, the above contents are merely embodiments of the present invention and are intended only to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
