Description

Technical Field

[0001] The utility model relates to the field of emergency disposal of waterborne anti-leakage pollution of shipped chemicals, in particular to an anti-oil spill device applied to an oil tank. Background Art

[0002] With the booming development of global oil trade, oil tankers have become an important bridge connecting oil-producing countries and consuming countries. However, during the oil transportation process, ships may encounter various risk factors such as bad weather, mechanical failures, and human operation errors. These risk factors may lead to accidents such as ship collisions, groundings, and capsizings, and then cause oil spills. In recent years, offshore oil spills and oil spill accidents have occurred frequently, causing serious economic losses and marine ecological damage. The pollution caused by oil spill accidents to the marine environment is extremely serious. Since the density of oil is less than that of water and it has a strong viscosity, the leaked oil often floats on the surface of the sea water. Under the combined action of waves, tides, and ocean currents, the leaked oil will quickly spread and cover a large area of the sea, causing direct harm to marine organisms and disrupting the marine ecological balance. At the same time, the harmful substances in the oil may enter the human body through the food chain, posing a threat to human health. In addition, oil spill accidents will also cause huge losses to economic industries such as fisheries and tourism in coastal areas, affecting the economic development of local society.

[0003] In order to prevent oil leakage accidents during oil transportation, ship designers and operators have taken various measures, such as strengthening the ship structure, improving the ship stability, and strengthening crew training. However, these measures cannot completely eliminate the risk of oil leakage. Therefore, developing a device specifically used to prevent oil from spilling during transportation is of great significance for reducing the risk of oil spill accidents, protecting the marine environment, and human health. The existing anti-oil spill measures mainly focus on preventing dispersion, that is, controlling after pollution occurs to prevent further spread of pollution. Generally, an oil boom is first used for containment, and then the internal crude oil is further processed. However, for the existing oil booms, when there are large waves on the sea surface, it is easy for the spilled oil to overflow from above the oil boom, and the containment effect is not good. The location where a ship runs into danger is often far from the shore, and the emergency department often cannot reach the oil spill accident site in time. In addition, the existing emergency equipment mainly relies on relatively primitive equipment such as oil booms, oil-absorbing adhesives, and surface oil skimmers. A large number of watercrafts, machines, and labor are required for laying, which is costly and inefficient, and cannot achieve rapid deployment and essentially prevent pollution. Therefore, there is an urgent need to find an effective solution in the current domestic and international ship transportation anti-leakage emergency disposal technology to reduce marine pollution.

[0004] In view of the above problems, it is necessary to propose an anti-oil spill device applied to an oil tank to solve the above problems. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an anti - oil spillage device applied to an oil tank. The side oil film and the bottom film are wound around the outer surface of the main column. When needed, it can be used after removing fixing components such as the bottom hoop. At the same time, the barrel - shaped film body formed by the unfolded side oil film and the bottom film can isolate the un - leaked crude oil and petroleum products in the oil tank from the damaged oil tank, preventing leakage from the source. The bottom film water bag ensures the complete unfolding of the bottom film body by pumping water into it. At the same time, the side oil film lower air bag ensures the complete opening of the top of the side oil film body by pumping gas into it. The combination of the two ensures the reliability of the structure during use. After the side oil film upper air bag is inflated, it can unfold the side oil film body longitudinally under the action of buoyancy, with a simple, efficient, and reliable process. The device does not use any electronic devices and uses inert gas and water as filling media, fully ensuring its safety.

The inner surface of the top end of the extension film is provided with a side oil film upper air bag. The side oil film upper air bag is annular and its diameter is slightly larger than that of the side oil film lower air bag.

[0009] The air and water guiding assembly includes a bottom pipe, a guide rail, an upper extension pipe, and a lower extension pipe. The bottom pipe is a flexible pipe installed inside the main column and passes through the main column. One end of the bottom pipe is connected to the bottom film water bag, and the other end extends to the upper end of the main column. The guide rail is arranged on the outer surface of the main column parallel to the main axis direction of the main column. A groove is provided along the entire length of the side of the guide rail, and a caster runs in the groove. The caster is installed on the vehicle body. The upper end of the vehicle body is installed with a first hose and a second hose, and the first hose and the second hose are arranged parallel to each other. The installation direction of the upper extension pipe is perpendicular to the sliding direction of the vehicle body.

[0014] Compared with the related technology, the beneficial effects of the present utility model are as follows:

[0015] The barrel-shaped film body composed of the side oil film and the bottom film can isolate the un-leaked crude oil and crude oil products in the oil tank from the damaged oil tank, preventing leakage from the source.

[0016] The side oil film and the bottom film are stored around the main column through upper, middle, and lower binding ropes and a bottom hoop, and can be quickly put into use.

[0017] After the water is pumped into the bottom film water bag, it can ensure the complete unfolding of the bottom. At the same time, after the inert gas is pumped into the lower air bag of the side oil film, it can ensure the complete opening of the top. The combined action of the two ensures that the structure has sufficient volume and also guarantees the reliability of the structure during use.
