Description

TECHNICAL FIELD

[0001] The present application relates to a cleaning device, belonging to the field of ship and ocean engineering, and particularly relates to a deck water cleaning device for a ship and an offshore platform. BACKGROUND

[0002] The ship and the offshore platform are long-term operated in the open sea environment, and water accumulation on the deck is inevitable due to rain, wind, or deck washing. The water accumulation on the deck surface will hinder personnel passage or deck surface construction. Since the water accumulation reduces the surface friction, it may even cause personnel or equipment to slip and cause safety accidents. In order to reduce or remove the water accumulation, the following measures are usually taken: 1. During the design and construction process, the control requirements for the deck surface levelness are proposed to avoid local depression and reduce the possibility of water accumulation; 2. A beam arch is arranged, that is, a certain slope is designed on the deck surface to ensure that the water flows smoothly to the side and is discharged; and 3. A certain number of drainage openings are arranged on the deck surface to facilitate the discharge of water outside the side.

[0003] During the actual design and construction process of the ship and the offshore platform, in order to ensure the construction and functional requirements of the deck surface, a certain levelness needs to be ensured, and the beam arch cannot be arranged. For a large-scale ship or offshore platform, even if the design requirements ensure the levelness of the wide deck surface, local depression will still occur inevitably. The arrangement position of the drainage opening is also limited by the internal structure of the ship body and the watertight compartment and cannot be arranged at will. Therefore, in many ship and offshore platform construction projects, the problem of deck water accumulation will inevitably occur. In the harsh environment on the sea, the water accumulation on the deck surface will hinder personnel passage or deck surface construction, greatly increasing the risk of safety accidents caused by personnel or equipment slipping, and there is a certain safety hazard. In the past, when similar situations occurred in projects, the ship personnel usually cleaned the water manually, which was time-consuming and laborious. The existing water suction device is designed for household use, which cannot be applied to the harsh environment of the ship and the ocean, and is not further optimized for the depression of the deck surface. Although the water suction device can be used to suck water, the efficiency of processing the water accumulation is low, and personnel need to be on duty for a long time, greatly increasing the work intensity.
