Description

Technical Field

[0001] The utility model belongs to the technical field of marine oil spill recovery, and in particular relates to a marine oil spill recovery device. Background Art

[0002] With the increasing demand for oil, the trade of petroleum products has been rising steadily, leading to the rapid growth of the oil transportation industry, especially the water-based oil transport ships that transport the largest amount of oil, which account for more than 60% of the total oil transportation volume.

[0003] At the same time, with the development of offshore oil transportation, marine oil pollution has attracted public attention. At present, marine oil spill accidents occur frequently, which will inevitably cause oil leakage not only in the process of offshore oil exploitation, but also in the process of port transportation. For example, at the crude oil terminal, when the device pipeline leaks, the ship enters and exits and collides, the loading and unloading equipment fails or the personnel make mistakes, it is easy to cause a large amount of crude oil leakage, thereby causing water environment pollution; and the leakage accident is bound to cause pollution to the nearby sea environment, which in turn causes damage to the seawater quality, aquaculture, fishery, seaside tourist attractions and human health.

[0004] At present, most traditional methods of marine oil spill recovery use a method of first using a ship to pull an oil spill recovery belt to circle the marine oil spill, and then using an oil suction machine to recover the oil spill. However, due to the large size of the ships used in this oil spill recovery method, it is only suitable for oil spill recovery operations in wide seas, but not in narrow rivers. Moreover, since a large amount of dust and dirty oil easily accumulate on the surface of the oil spill belt, it is also necessary for staff to clean the oil spill belt in a timely manner, thereby wasting a lot of manpower and material resources, increasing costs, and reducing work efficiency. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a marine oil spill recovery device which can efficiently recover spilled oil in wide sea areas and in narrow rivers, so as to overcome the defects of existing marine oil spill recovery methods such as limited adaptability to the environment, low working efficiency and high energy consumption.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a marine oil spill recovery device, which includes a main hull, which is provided with a cab, a hull, and a propeller in sequence from front to back, an oil-water separator is provided in the middle of the hull, and the oil-water separator is provided with an oil spill input port, an oil spill output port and a drain port. The oil spill input port of the oil-water separator is connected with a suction pipeline, the suction pipeline is rotatably installed on the hull through a rotating component, and the front end of the suction pipeline is provided with an oil spill recovery port, and the oil spill recovery port is arranged at the head of the hull; the oil spill output port of the oil-water separator is connected with an oil spill storage component through an inlet pipeline, and an oil pump is arranged in the middle of the inlet pipeline; the drain port of the oil-water separator is connected with a discharge pipeline, a water pump is arranged in the middle of the discharge pipeline, and the lower end of the discharge pipeline directly passes through the bottom of the hull.

[0007] In this way, when the utility model is driven to perform marine oil spill recovery operations, the seawater containing dirty oil can be first sucked into the oil-water separator from the oil spill recovery port under the combined action of the oil pump and the water pump, and then the seawater is separated from the oil and water by the oil-water separator, and the separated dirty oil is discharged into the oil spill storage component through the inlet pipeline for storage, and the separated seawater is discharged through the discharge pipeline. In addition, in this process, since the suction pipeline and the oil spill recovery port arranged at the front end of the suction pipeline in the utility model can be rotated under the drive of the rotating component, the utility model can adjust the angle of the oil spill recovery port, thereby effectively expanding the scope of oil spill recovery of the entire device, so as to solve the problem that the hull is not conducive to turning when recovering dirty oil in narrow rivers and docks, and thus broaden the adaptability of the entire device; at the same time, since the utility model recovers marine oil spills through the suction force generated by the oil pump and the water pump, the influence of waves generated during the forward movement of the ship is solved; since the utility model can discharge seawater in time and store dirty oil in a centralized manner, it can also increase the working time of the entire device, thereby effectively improving the working efficiency and saving energy consumption.

[0008] Furthermore, the oil-water separator includes a separator body installed in the middle of the hull, the interior of the separator body is divided into a front cabin and a rear cabin by a transverse bulkhead, the front cabin and the rear cabin are connected through an oil-water filter arranged at the upper end of the transverse bulkhead, and an oil spill inlet is arranged at the upper part of the front end surface of the front cabin, a drain outlet is arranged at the rear end of the bottom surface of the front cabin, an inlet baffle is arranged at the front end of the top surface of the front cabin, the lower end of the inlet baffle is lower than the oil spill inlet, an oil-water separation membrane is arranged between the inner side of the inlet baffle and the transverse bulkhead, and the oil-water separation membrane is located below the oil-water filter; an oil spill outlet is arranged at the rear of the rear cabin. In this way, when seawater enters the oil-water separator, the seawater will pass through the oil-water separation membrane and the oil-water filter in sequence, and will undergo primary oil-water separation treatment and secondary oil-water separation treatment in sequence through the oil-water separation membrane and the oil-water filter, thereby improving the oil-water separation effect of the oil-water separator.

[0009] Furthermore, the discharge pipeline is provided with a one-way valve 1, and the inlet pipeline is provided with a one-way valve 2. The flow direction of the material at the one-way valve 1 is from the oil-water separator to the outside of the hull, and the flow direction of the material at the one-way valve 2 is from the oil-water separator to the oil spill storage component, and the functions of pumping water and draining water are realized through the cooperation of the one-way valve 1, the one-way valve 2 and the water pump and the oil pump.

[0010] Furthermore, the rotating assembly includes a base, which is fixedly mounted on the hull by fasteners, a rotating shaft is installed in the middle of the base for horizontal rotation, the rotating shaft is connected to a rotating drive mechanism, one end of the rotating shaft is fixedly connected to a transmission gear after extending into the hull, the transmission gear is meshed with a fixed gear, and the fixed gear is fixedly mounted on the suction pipeline. In this way, the utility model only needs to control the rotating drive mechanism to drive the suction pipeline to rotate horizontally in the corresponding direction through the cooperation between the rotating shaft, the transmission gear, and the fixed gear, so as to achieve the angle adjustment of the oil spill recovery port set at the front end of the suction pipeline. And as a preference, the part of the rear end of the suction pipeline used to connect to the oil-water separator preferably adopts a flexible pipeline such as a bellows, and the part of the front end of the suction pipeline used to connect the fixed gear and the part where the oil spill recovery port is set preferably adopts a rigid pipeline such as a stainless steel pipe.

[0011] Furthermore, a set of rotating components is respectively arranged on the upper part of the hull and the bottom part of the hull, and the two rotating components are symmetrically arranged with the suction pipeline as the symmetry center.

[0012] Furthermore, the oil spill storage assembly includes a dirty oil tank disposed in the hull, the oil inlet of the dirty oil tank is connected to the tank inlet pipeline, an oil discharge port is provided between the bottom surface of the dirty oil tank and the lower side of the hull, a check valve 3 is provided in the oil discharge port, and the flow direction of the material at the check valve 3 is from the dirty oil tank to the outside of the dirty oil tank. In this way, the utility model can realize the dirty oil discharge action through the cooperation between the check valve 3 and the oil discharge port.

[0013] Furthermore, the propeller is a pod-type propeller, which is arranged below the stern of the hull and provides forward power for the entire main hull.

[0014] It can be seen from the above technical scheme that the utility model has the following advantages: when driving the utility model to perform marine oil spill recovery operations, since the suction pipeline and the oil spill recovery port arranged at the front end of the suction pipeline in the utility model can be rotated under the drive of the rotating component, the utility model can adjust the angle of the oil spill recovery port, thereby effectively expanding the scope of oil spill recovery of the entire device, so as to solve the problem that the hull is not conducive to turning when recovering dirty oil in narrow rivers and docks and other places, thereby broadening the adaptability of the entire device to the environment; at the same time, since the utility model recovers marine oil spills through the suction force generated by the oil pump and the water pump, the influence of waves generated during the ship's forward movement is solved; since the utility model can discharge seawater in time and store dirty oil in a centralized manner, it can also increase the working time of the entire device, thereby effectively improving the working efficiency and saving energy consumption.
