It can improve the overall pressure resistance of the pipeline and effectively reduce the noise generated during use. It can improve the thermal insulation effect and reduce losses during cooling and heating operations. By setting a dustproof net 2 and a cleaning component, the dustproof net 2 is used to isolate dust in the outside air to prevent dust and impurities from entering the inside of the pipeline. The cleaning component is used to clean the dustproof net 2 to prevent dust accumulation and blockage. By setting a connecting frame 8 and a locking component, the connecting frame 8 is used in conjunction with the locking component to quickly realize the disassembly and assembly of the pipeline and the equipment, thereby improving work efficiency.

[0026] Among them, a rotating rod 6 is rotatably provided inside the inner tube 13, the rotating rod 6 is rotatably connected to the dustproof net 2 and a cleaning plate 7 is fixed to the end of the rotating rod 6, the cleaning plate 7 is in contact with the surface of the dustproof net 2, and a driving component for driving the rotating rod 6 to rotate is provided in the inner tube 13. By setting the driving component, the rotating rod 6 and the cleaning plate 7, the driving component can be used to drive the rotating rod 6 to rotate, and the rotation of the rotating rod 6 drives the cleaning plate 7 to rotate synchronously to clean the dust on the surface of the dustproof net 2, without the need for users to repeatedly disassemble and clean, thereby improving convenience.

[0027] Among them, the driving component includes a rotating shaft 3 rotatably installed inside the inner tube 13, and bevel gears 5 are fixed on the outer surface of the rotating shaft 3 and the end of the rotating rod 6, and the two bevel gears 5 are meshed with each other. The positions of the rotating shaft 3 on both sides of the bevel gear 5 are fixed with a plurality of blades 4 used in conjunction with each other. By setting the rotating shaft 3, the blades 4 and the bevel gear 5, when the work starts, airflow enters the inside of the pipeline, and the airflow drives the blades 4 to rotate and drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the rotating rod 6 to rotate through the bevel gear 5, and can further drive the cleaning plate 7 to move through the rotating rod 6, so as to realize the cleaning work of the dustproof net 2. The airflow drive does not need to use a motor or other equipment separately.

[0028] Among them, the inner tube 13 is fixedly provided with an air guide plate 17 used in conjunction with the fan blades 4. By providing the air guide plate 17, the airflow can be guided by the air guide plate 17 to ensure that the airflow can drive the fan blades 4 to rotate, thereby improving the stability of use.

[0029] Among them, a number of positioning bolts 9 are slidably arranged on the connecting frame 8, and the ends of the positioning bolts 9 are fixed with mounting plates 10. By setting the mounting plate 10 and the positioning bolts 9, the movable plate mounting plate 10 drives the mounting plate 10 to move the positioning bolts 9, and the positioning bolts 9 are inserted into or pulled out of the sockets opened on the equipment, thereby realizing the installation and disassembly work.

[0030] Among them, a spring 11 is sleeved on the surface of the positioning bolt 9, and the two ends of the spring 11 are respectively fixed on the connecting frame 8 and the mounting plate 10. By setting the spring 11, the spring 11 can drive the positioning bolt 9 to automatically return to its original position, so that the positioning bolt 9 can be stably inserted into the socket of the connecting device, thereby improving stability and avoiding problems such as the positioning bolt 9 falling off.

[0031] Among them, a rotating ring 12 is rotatably installed on the connecting frame 8, and a plurality of arc-shaped protrusions used in conjunction with the mounting plate 10 are provided on the rotating ring 12. By setting the rotating ring 12, the arc-shaped protrusions on the surface are released from the mounting plate 10 by rotating the rotating ring 12. The arc-shaped protrusions are driven to move by the rotating ring 12, and the plurality of mounting plates 10 can be synchronously driven to drive the positioning bolts 9 to move synchronously, so that the positioning bolts 9 are disengaged from the sockets and released from fixation, thereby improving the disassembly efficiency.

[0032] When in use, rotating the rotating ring 12 drives the arc-shaped protrusion to move. The movement of the arc-shaped protrusion can synchronously drive several mounting plates 10 to drive the positioning bolts 9 to move synchronously to avoid interference with the connection with the equipment. The connecting equipment is connected to the connecting frame 8, and the rotating ring 12 is continued to be rotated to make the arc-shaped protrusion away from the mounting plate 10. The positioning bolt 9 will automatically be inserted into the socket opened on the connecting equipment under the elastic force of the spring 11 to complete the connection with the equipment. When working, airflow enters the inside of the pipeline, and the airflow drives the fan blades 4 to rotate and drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the rotating rod 6 to rotate through the bevel gear 5, and can further drive the cleaning plate 7 to move through the rotating rod 6, so as to automatically realize the cleaning of the dustproof net 2.
