In a preferred embodiment, as shown in fig. 4-9, the single length of pipe unit 100 has two cover plates 150 inside, and the two cover plates 150 are located at the top and bottom of the single length of pipe unit 100, respectively. The cover plate 150 extends along the ventilation direction of the ventilation cavity, two extending ends of the cover plate 150 are connected with a connecting plate 140, and the connecting plate 140 is provided with a plug hole 141.
