An unmanned oil spill automatic recovery emergency ship

Abstract

The invention discloses an unmanned oil spill automatic recovery emergency ship, which comprises an emergency ship body for automatic recovery of oil spill, and the bottom of one end of the emergency ship body is provided with an oil-water separator for separating water and oil cabin, the entrance of the oil-water separation cabin is provided with a lead-in belt for introducing the oil-water mixture, and an oil level sensor for detecting the oil level is also provided at the entrance. The support adjustment mechanism for adjusting the position of the oil level, this unmanned oil spill automatic recovery emergency ship, by setting the existing weir plate with a relatively fixed structure as the introduction belt, the introduction belt can not only introduce the oil-water mixture stably In the oil-water separation tank, it can be adjusted according to the position of the oil level, so that the oil-water mixture is introduced into the oil-water separation tank, avoiding the formation of a certain space that is the same as the air, and improving the oil-water separation efficiency in the weir-type oil skimmer.

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...

AI Technical Summary

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
