Problems solved by technology
Although the existing method solves the problem of uneven interior installation and gaps of the tuyere device, the size of the tuyere device needs to be researched and assembled according to different trains and cut by scribing lines. Therefore, the standardization and mass production of the tuyere device cannot be realized production, resulting in low production and installation efficiency of the tuyere device, labor-intensive and time-consuming installation, and increased production and installation costs of the tuyere device

The invention discloses an air inlet device. The air inlet device comprises a grating, an adjusting sliding chute and frames, wherein the adjusting sliding chute is fixed to the grating and parallel to the length direction of the grating, and the frames are located on the wide sides of the two sides of the grating and connected to the adjusting sliding chute, and can move on the adjusting sliding chute in the length direction of the grating. In the air inlet device, the gap L1 between the frames and the wide sides of the grating is adjusted by moving the frames in the adjusting sliding chute in the length direction of the grating, so that the whole length size of the air inlet device is changed, and uniformity of the gap L2 between the air inlet device and a dividing wall after the air inlet device is mounted is controlled. The length of the air inlet device can be adjusted, and therefore line marking and size cutting do not need to be conducted after the air inlet device is researched and mounted in situ for different train internal mounting structures, standardized and massive production of the air inlet device are achieved, and mounting efficiency of the air inlet device is improved.
Description
technical field [0001] The invention relates to the technical field of train ventilation systems, in particular to a tuyere device. Background technique [0002] The tuyere device is located on the top of the train indoor car, is arranged between the two partition walls of the train and is connected with the indoor roof, and is used for ventilation of the train ventilation system. At present, there will be dimensional errors during the installation of the internal structure of the train. For example, the installation of the roof and partitions will deviate from the previous installation position, resulting in uneven gaps between the tuyere devices and the partitions and roofs when the tuyere device is installed. [0003] In view of the above situation, the existing solution is that according to the different conditions of the internal installation structure of each train, the tuyere device needs to be scribed and cut to size after research and installation on the existing ve...
