Abstract
The invention relates to a movable hatch cover prefabricated cabin, a hatch cover of the movable hatch cover prefabricated cabin and a waterproof connecting piece. The strip-shaped waterproof connecting piece is arranged at the bottom of the hatch cover, the lower portion of the waterproof connecting piece is of a U-shaped groove structure, and the first side groove wall of the U-shaped groove structure is detachably fixed to the outer side of a top frame so as to fix the hatch cover to a cabin body. Therefore, the hatch cover can be dismounted from the cabin body when needed, so that equipment goes in and out of the top. Meanwhile, the second side groove wall of the U-shaped groove structure extends upwards and is connected with a top plate, water leak holes are formed in the bottom of the U-shaped groove structure, therefore, the second side groove wall can achieve the function of preventing rainwater or snow water from entering the cabin body, even though water enters the cabin body from the connecting position of the second side groove wall and the top plate, the water can enter the U-shaped groove structure and flow out of the water leak holes and cannot enter the cabin body, and good waterproofness is achieved.
