Description

Technical Field

[0001] The utility model relates to the technical field of fan pipelines, in particular to a fan pipeline which is easy to splice. Background Art

[0002] Fan duct is an important component of the ventilation system. It is usually made of metal or non-metallic materials and is used to transport air or other gases. Fan duct has good sealing and pressure resistance, which can ensure the smooth flow of gas in the duct. Its design and installation need to be carried out according to actual needs to meet the ventilation requirements of different scenarios. In the industrial field, fan duct can be used to remove harmful gases, dissipate heat, etc. In buildings, it can realize the circulation and regulation of indoor air. High-quality fan duct can improve ventilation efficiency, reduce energy consumption, and create a comfortable and safe environment for people.

[0003] There is a utility model in the prior art such as the publication number CN206458650U. The utility model relates to the field of ventilation equipment, specifically a duct fan, including a shell and a centrifugal fan located inside the shell, and air outlets for air inlet and outlet are arranged on opposite sides of the shell, and a barrier layer for sealing itself is arranged in the air outlet, and the barrier layer includes a plurality of adjacently arranged long strip baffles, and the two ends of the baffles are respectively abutted against the edge of the air outlet and are rotatably matched, and a linkage assembly is arranged between the baffles in the air outlet, and a rotating part is also arranged on the shell, and the rotating part drives the baffles to rotate synchronously through the linkage assembly to form a plurality of air ducts. When the duct fan is in normal use, wind flows out from several air ducts formed by adjacent baffles. When the duct fan is out of use, the rotating part drives any baffle to rotate. Due to the setting of the linkage assembly, all the baffles rotate synchronously to form a barrier layer, thereby achieving the purpose of closing the air outlet and preventing foreign matter from entering the fan. This ensures that the duct fan can continue to be used normally and is beneficial to extending the service life of the fan. However, the pipeline is connected by a large number of bolts during the installation process. When the pipeline fails and needs maintenance, it needs to be disassembled with the help of tools, which consumes a lot of time.
