Description

Technical Field

[0001] The present invention relates to the technical field of oil pollution treatment equipment, and particularly relates to an oil boom with automatic inflation and deflation and storage functions. Background Art

[0002] Nowadays, with the increasing activities of human beings in offshore oil exploration, transportation and storage, the probability of occurrence of offshore oil spills is increasing day by day, and oil pollution has increasingly become an inevitable problem facing marine pollution. According to statistical data, only about 1.5 million tons of oil enter the ocean due to oil tanker accidents every year, and the amount of oil flowing into the ocean every year is between 2 million tons and 20 million tons. The situation of emergency response to offshore oil spills is becoming increasingly severe. Moreover, the floating oil on the water surface poses a great threat to the marine ecological environment. Anatomical analysis of the body tissues of dead sea turtles during the oil spill shows that 61% of the digestive tracts of sea turtles contain petroleum aromatic hydrocarbons. Heavy metals and other toxins have appeared in the blood and endocrine systems of the workers cleaning the floating oil on the sea surface, which will lead to an exponential increase in their cancer incidence rate.

[0003] In the prior art, oil-water separation devices using superhydrophobic and superoleophilic materials are disclosed in Chinese patents CN201010554373, CN201310160287, CN201410023962, CN201520629674, etc. However, after these devices work in water for a long time, a "water ring" will be generated around the devices, and the floating oil on the water surface cannot contact the superhydrophobic and superoleophilic materials, affecting the separation efficiency of the oil-water separation devices. They can only be used in small-scale static water surfaces and cannot be extended to the collection of floating oil in large areas of water.

[0039] The following will describe the specific embodiments of the present invention in more detail with reference to the schematic diagrams. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0040] AsFigure 1 As shown, this embodiment provides an oil boom with automatic inflation, deflation and storage functions, including an oil boom body 1, an oil collection mechanism 2 and an oil boom recovery mechanism 30. The oil boom body 1 includes a plurality of oil boom modules connected end to end in sequence, such as Figure 2 As shown, the oil boom module includes a square skirt 3, a flexible support 4 for holding the skirt 3 open is provided on the top of the skirt 3, a first counterweight 5 is provided on the bottom, and floating components with automatic inflation and deflation functions are provided on both sides of the skirt 3. Connectors 17 are provided on both sides of the skirt 3, and two adjacent oil boom modules are connected to each other through the connectors 17.

[0041] The floating assembly includes a first airbag 6 and an automatic inflation device connected to the first airbag 6, and an automatic deflation device 7 is provided on the first airbag 6. The automatic inflation device includes a carbon dioxide gas cylinder 14, an automatic inflation assembly and a connecting hose 15, and the automatic inflation assembly is arranged in the bottle mouth of the carbon dioxide gas cylinder 14, and one end of the connecting hose 15 is connected to the bottle mouth of the carbon dioxide gas cylinder 14, and the other end is connected to the first airbag 6.

[0042] like Figure 3 As shown, the automatic inflation assembly includes a metal inner film 21, a water-soluble reagent 22, a spring 23 and a metal ejector pin 24. Among them, the metal inner film 21 is sealed in the bottle mouth of the carbon dioxide gas cylinder 14. The metal inner film 21 needs to have high strength and sealing performance and needs to withstand a high pressure of about 10Mpa. The spring 23 is in a stretched state, the metal ejector pin 24 is fixedly connected to one end of the spring 23 and the other end is fixedly connected to the inner wall of the bottle mouth of the carbon dioxide gas cylinder 14. The tip of the metal ejector pin 24 is fixed in the water-soluble reagent 22. When the water-soluble reagent 22 dissolves after encountering water, the spring 23 contracts and drives the metal ejector pin 24 to pierce the metal inner film 21. The carbon dioxide gas cylinder 14 releases liquid carbon dioxide, and inflates the first airbag 6 through the connecting hose 15, so that the oil boom floats on the sea surface. The appropriate height of the oil boom floating on the sea surface is adjusted by adjusting the weight of the first counterweight block 5.

[0043] like Figure 4As shown in the figure, the automatic air release device 7 includes a toggle switch 33, a slip ring 32, a substrate 31, a connecting rod 34, and a blade 35. The substrate 31 is circular, and a through hole is concentrically arranged in the middle. The slip ring 32 is rotatably installed on the substrate 31 concentrically, and the toggle switch 33 is arranged on the slip ring 32 extending radially along the slip ring 32. A plurality of blades 35 are provided, and the plurality of blades 35 are arranged in a circumferential array around the through hole. One side of each blade 35 is rotatably connected to the substrate, and the other side of each blade 35 is respectively rotatably connected to the slip ring 32 through a corresponding connecting rod 34. The toggle switch 33 drives the axial rotation of the slip ring 32 to drive the plurality of blades 35 to move so that the through hole is in an open state or a closed state. When the through hole is in an open state, the first airbag 6 communicates with the outside; when the through hole is in a closed state, the first airbag 6 is in a sealed state.

[0044] As Figure 5 shown, the oil collection mechanism 2 includes an oil collection tank 8, an oil inlet arranged at the top on one side of the oil collection tank 8, a second airbag 9 arranged on the outer wall of the oil collection tank 8, and an oil recovery port 10 arranged on the outer wall of the oil collection tank 8. An oil-loving and water-repellent stainless steel mesh 11 is arranged on the oil inlet. The oil-loving and water-repellent stainless steel mesh 11 is used for separating oil and water from the oil floating on the sea surface. The height of the second airbag 9 is almost the same as the height of the oil inlet, so that the oil floating on the sea surface can flow into the oil collection tank 8. The oil recovery port 10 is connected to an external oil pump, and the oil collected in the oil collection tank 8 is pumped out and recovered through the oil pump. A connecting member 17 is also arranged on the side wall of the oil collection tank 8, and is connected to the end of the oil containment boom body 1 through the connecting member 17 to form a closed-loop structure, as Figure 9 shown, the oil spill is enclosed within the closed-loop structure formed by the oil containment boom body 1, the oil collection mechanism 2, and the oil containment boom recovery mechanism 30.

[0045] As Figure 1 shown, the oil containment boom recovery mechanism 30 includes a recovery chamber 12, an airbag compression module arranged in the recovery chamber 12, and an oil containment boom winding module, as Figure 6 Third airbags 13 are arranged on the outer walls on both sides of the recovery chamber 12, and two second counterweights 16 are symmetrically arranged on both sides of the bottom of the recovery chamber 12. One end of the oil containment boom module of the oil containment boom body 1 passes through the airbag compression module and is connected to the oil containment boom winding module. The airbag compression module is used to compress the first airbag 6 after opening the automatic air release device 7.

[0046] As Figure 7 and Figure 8As shown in the figure, the airbag compression module includes an inclined pad 61, a first lower bracket 62, a first lower gasket 63, two extrusion rollers 64, a first upper fixing piece 67, a valve toggle switch 65, an oil fence fixing piece 66, a first motor 69, and a motor mounting piece 68. The first motor 69 is fixedly installed on the first upper fixing piece 67 through the motor mounting piece 68. The two extrusion rollers 64 are arranged oppositely. The extrusion rollers 64 are rotatably connected to the first lower bracket 62, and the first motor 69 is drivingly connected to the extrusion rollers 64. The valve toggle switch 65 cooperates with the toggle switch 33 to forwardly or reversely toggle the toggle switch 33, thereby opening or closing the first airbag 6.

[0047] When recycling the oil fence body, the valve toggle switch 65 reversely toggles the toggle switch 33 to open the first airbag 6. The extrusion rollers 64 compress the first airbag 6, thereby reducing the winding volume.

[0048] As Figure 7 shown in the figure, the oil fence winding module includes a second lower bracket 70, a second lower gasket 71, a winding drum 73, a traction member 72, a second upper fixing piece 74, and a second motor 75. The upper surface height of the second lower bracket 70 is the same as that of the first lower bracket 62. The winding drum 73 is rotatably installed between the second lower bracket 70 and the second upper fixing piece 74. One end of the traction member 72 is connected to the oil fence module at one end of the oil fence body 1, and the other end is connected to the outer wall of the winding drum 73. The second motor 75 is fixedly installed on the second upper fixing piece 74 and is drivingly connected to the winding drum 73. The second lower gasket 71 is arranged on the upper surface of the first lower bracket 62.

[0049] After an oil spill accident occurs on the sea surface, tow this oil fence to the vicinity of the oil spill area. Use the oil fence laying ship to connect the rear connecting piece of the ship to the left-end connecting piece of the first section of the oil fence body. The oil fence winding module inside the oil fence recycling mechanism is in a relaxed state.

[0050] When the oil fence laying ship starts, the oil fence body is towed out section by section. Along the upper track, the deflation valve of the automatic deflation device 7 is toggled to close. Then, the carbon dioxide gas cylinder touches water and quickly releases carbon dioxide, making the oil fence body float on the water surface. As it is towed, the oil fence modules connected section by section continuously enclose until the oil spill area is enclosed.

[0051] At this time, the oil fence laying ship disconnects the rear connecting piece of the ship and connects the left-end connecting piece of the first section of the oil fence module to the right-end connecting piece of the oil collection mechanism to fix the enclosure as Figure 9 shown in the figure. At this time, start the oil fence collection device to continuously reduce the length of the oil fence. At this time, the oil fence body enters the upper fixed track through the airbag compression module inside the oil fence recycling mechanism. The automatic deflation device 7 is opened in advance, and then the first airbag is compressed and deflated, so the overall volume of the oil fence body is reduced.

[0052] Meanwhile, the oil collection mechanism is also constantly working. After the oil passes through the oil-loving and water-repellent stainless steel mesh, the oil enters the inside of the oil collection tank 8, and the water is blocked outside. For the empty oil area generated, due to the continuous shortening of the oil containment boom, the enclosed area is continuously reduced, and the floating oil spills continuously gather, filling the empty oil area, enabling the oil collection mechanism to keep working. When it is almost completed, disconnect the connection between the right end of the oil collection mechanism and the first oil containment boom module, so that the entire oil containment boom can be wound up.

[0053] When the oil spill treatment is completed, the device is put back into the ship, and the suction pump is used to connect to the oil recovery port 10 at the rear end of the oil collection mechanism to pump out the collected oil spills, thus completing an oil spill treatment event.

[0054] The above is only the preferred embodiment of the present invention and does not impose any limitation on the present invention. Any person skilled in the art, within the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification and other changes to the technical solution and technical content disclosed by the present invention, which are still within the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
