Unmanned spilled oil automatic recovery emergency ship

Abstract

The invention discloses an unmanned spilled oil automatic recovery emergency ship which comprises an emergency ship body used for automatically recovering spilled oil; an oil-water separation cabin used for separating water and the oil is arranged at the bottom of one end of the emergency ship body; a leading-in belt used for leading in an oil-water mixture is arranged at an inlet of the oil-water separation cabin; an oil level sensor for detecting a oil level is further arranged at the inlet; and a supporting and adjusting mechanism for adjusting the leading-in belt according to the position of the oil level on the water surface is arranged in the oil-water separation cabin. According to the unmanned spilled oil automatic recovery emergency ship, a weir plate which is relatively fixed in an existing structure is set as the leading-in belt, the leading-in belt not only can be used for stably introducing the oil-water mixture into the oil-water separation cabin, but also can be adjusted according to the position of the oil level, so that in the process of introducing the oil-water mixture into the oil-water separation cabin, a certain space which is the same as air is prevented from being formed, and the oil-water separation efficiency in a weir type oil skimmer is improved.

Description

technical field [0001] The invention relates to the technical field of recovery emergency ships, in particular to an unmanned automatic oil spill recovery emergency ship. Background technique [0002] With the continuous expansion of offshore oil exploration and transportation, oil spills have become a major source of danger for marine environmental pollution. A large amount of crude oil and its refined products leak into the marine environment when oil spills occur, which will affect the local marine ecological environment. Bring catastrophic damage, and cause huge economic losses and seriously endanger human health. [0003] In order to reduce the damage of oil spill to the marine environment, it is necessary to take effective technical measures immediately to deal with the oil spill pollution on the water surface. At present, the emergency control methods of oil spill pollution mainly include combustion method, chemical method, biological method, mechanical recovery meth...

Problems solved by technology

When the ship is moving forward, the oil spilled on the surface of the water enters the oil-water separation tank through the adjustable weir plate or the oil sweeping arm. Using the difference in specific gravity of oil and water, the oil and water are naturally separated, and the water at the bottom of the tank is discharged to recover the oil. However, the existing weir plate structure is relatively simple. At the same time, the whole is relatively fixed, and it is vertically distributed with the oil-water separation tank, and it is difficult to adjust. When the oil-water mixture flows through the weir plate, there is a space in the lower part of the water flow that communicates with the air, causing the flow to be unstable. When the water head at the top of the weir is small, the overflow of the oil-water mixture will be affected by the surface tension, and the outflow will be unstable, thus affecting the oil-water separation effect of the weir oil skimmer
