Implement above-mentioned technical proposal, the water on cabin top enters drainage cavity by the first discharge outlet and the second discharge outlet, passes through row
Rainwater is discharged water pipe, prevents cabin from pushing up ponding.
Further, it is plugged with water-ring in first discharge outlet and the second discharge outlet, the ring-side wall that blocks water blocks
Gap between first discharge outlet and the second discharge outlet.
Implement above-mentioned technical proposal, the gap between the first discharge outlet and the second discharge outlet is blocked by water-ring, makes water
Cabin will not be entered by the gap between the first discharge outlet and the second discharge outlet.
Further, the cabin bottom is equipped with pedestal, and the pedestal includes bottom plate and support column, and the support column is vertical
It is connected to cabin bottom, bottom plate is set to one end on support column far from cabin and parallel with cabin bottom.
Implement above-mentioned technical proposal, support column improves distance between cabin and ground, when ground is risen, plays certain
The effect that surface water is isolated with cabin.
In conclusion the invention has the following advantages:
(1) when annular slot is plugged on annular protrusion, unidirectional retainer ring is by first annular slot and the second annular groove to annular
Card slot and annular protrusion limit, prevent annular slot from being detached from from annular protrusion, and on the other hand annular snap can be improved in unidirectional retainer ring
Leakproofness between slot and annular protrusion prevents steam from entering cabin；
(2) illumination can be shone into cabin by daylighting platform, and the lighting problem of cabin is solved on daytime, have and save the excellent of electric energy
Point.
