Meanwhile, considering that grease attached to deck equipment is possibly mixed into rainwater (or snow water), if the grease is directly discharged into the sea, the local marine environment is possibly damaged, so that for a part of specially designed ships or ocean engineering platforms, the side drain holes of the deck are eliminated, and the rainwater (or snow water) on the deck is collected and treated through a pipeline system and equipment to reach the standard and then discharged into the sea.
However, for such ships or ocean engineering platforms which are still in the process of construction, the pipeline systems and equipment are not in place, and the rainwater (or snow water) storage tanks have no use conditions, so that after the total assembly, once the rainwater is collected, a large amount of water accumulation on the deck surface is easily caused, and the construction plan and the construction quality are adversely affected. In addition, because of the great safety risk of the electric operation performed on the deck in rainy days, the conventional water pump drainage scheme cannot be adopted.

Detailed Description
In order to enhance the understanding of the present utility model, the present patent will be further described in detail with reference to the following examples, which are only for the purpose of explaining the present patent and do not constitute a limitation to the protection scope of the present patent.
Example 1
As shown in fig. 1, the device comprises a shell 1, a supporting leg 2, a suction port pipe 3, a suction port valve 4, an outlet hard pipe 5, an outlet valve 6, an outlet hose 7, a vent pipe 8, a vent pipe valve 9, an upper cover 10, a lifting eye plate 11 and a liquid level observation mirror 12.
The suction port pipe 3 is arranged at the bottom of the device and is provided with a suction port valve 4, the suction end adopts a horn mouth shape and has a certain height from the plane of the deck, so that the suction of the deck ponding is facilitated, and meanwhile, the mixing of large particle foreign matters is prevented.
The outlet hard pipe 5 is arranged at the lower part of the side surface of the device, and is provided with an outlet valve 6, the height and the length of the pipeline of the outlet hard pipe can lead the outlet hard pipe to cross the side plate of the ship body, so that the outlet is ensured to be positioned outside.
