Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Examples

As shown in the figure, the prefabricated cabin ventilation mechanism comprises a ventilation pipeline 1 with a trapezoidal section, wherein the section of the ventilation pipeline is in a hollow pentagonal prism shape, an air outlet is formed in the left side face of the ventilation pipeline 1, a connecting wing plate 2 is arranged around the air outlet, and the connecting wing plate 2 is fixedly connected with a prefabricated cabin wall body. And a through hole corresponding to the air outlet is reserved on the wall body of the prefabricated cabin, and a fan is arranged on the other side of the through hole. The bottom surface of the ventilation pipeline 1 is provided with an air inlet, and after the fan is started, external fresh air is sucked into the air outlet from the air inlet and is led into the prefabricated cabin, so that the purpose of gas exchange is achieved. The air inlet faces the bottom surface, and the entering of rainwater is reduced.

The bottom of the right side face of the ventilation pipeline 1 is provided with a drawing and inserting opening 11, the upper edge of the drawing and inserting opening 11 is provided with an upper baffle 6, and the upper baffle 6 is vertically and fixedly connected with the ventilation pipeline 1. The two sides of the air inlet are provided with lower baffles 5, and the lower baffles 5 are vertically and fixedly connected with the ventilation pipeline 1.

The dustproof filter plate 3 is arranged in the drawing-inserting opening 11. The dustproof filter plate 3 comprises a plug box 31 and dustproof cotton 33 arranged in the plug box 31. The plug buckle box 31 comprises a buckle box cover 312 and a bottom plate 311, wherein the buckle box cover 312 is fixedly connected with the bottom plate 311 through screws.
