Description

Technical Field

[0001] The invention belongs to the technical field of offshore fences, and in particular relates to an offshore fire-proof oil pollution containment boom. Background Art

[0002] As global offshore oil exploration and development progresses from shallow waters to deep seas, operational risks increase, and the frequency of offshore oil spills increases accordingly. After an offshore oil spill occurs, booms are a common method used internationally to contain oil spills, as they can effectively and promptly control the spill without causing additional pollution. However, offshore oil spills are often accompanied by fires, and fire-resistant booms are necessary to effectively contain the burning oil.

[0003] The existing technology (Patent Application No. CN109736277B, titled "A Marine Rapid Sewage Suction Device, Sewage Suction Boom, and Sewage Suction Boom System") offers excellent recovery performance, high efficiency, a simple structure, and a high degree of automation. The suction boom formed by this device can be used in large polluted areas to intercept and recover pollution sources, effectively controlling them. However, during the implementation of this technical solution, at least the following problems were discovered in the existing technology.

[0004] The currently used offshore fire-proof oil booms require a large amount of ship deck air supply resources and operating personnel during operation. At the same time, it is also necessary to disembark and drag the fire-proof oil booms to the incident area, resulting in very low efficiency in their deployment and fire-proof oil containment. Therefore, the current domestic fire-proof oil booms cannot effectively carry out containment operations and cannot meet the long-term effective containment needs under high temperature conditions.

[0019] The offshore fire-proof oil pollution boom of the present invention has the following advantages:

[0020] 1. This offshore fire-proof oil boom, during the fire-proof oil containment in the offshore incident area, first uses a double-headed motor to provide a unified drive source, saving power costs. The main bevel gear and the auxiliary bevel gear are meshed and driven together, and then the planetary bevel gear and the differential bevel gear on the rotating shaft are used for variable speed cooperation. The four drive shafts drive the four sets of propellers to rotate synchronously, providing driving force for the water rower. The water rower can quickly drag the fire-proof oil boom to the incident area, and carry out fire-proof oil containment operations on the oil on the sea surface in the incident area in the first time. This not only improves the deployment efficiency of the fire-proof oil boom, but also prevents the oil on the sea surface in the incident area from further expansion and spillage.

[0021] 2. This offshore fire-proof oil boom is first driven by the synchronous transmission of the main synchronous wheel and the auxiliary synchronous wheel on the rotating shaft, and the concave rod frame, connecting rod and piston realize reciprocating work in the cylinder barrel, and then the pressurized air source generated in the cylinder barrel is supplied to the pressure storage chamber reserved in the floating plates on both sides of the water rower through the supply pipe on the three-way valve, providing real-time supply measures for the subsequent deployment of the fire-proof oil boom. There is no need for the air supply equipment on the ship deck to remotely supply the fire-proof oil boom, which saves the cost of supply equipment and has a high air supply responsiveness.

[0022] 3. The offshore fire-proof oil-polluted boom first supplies the pressurized gas source in the pressure storage chamber into a plurality of groups of float balloons through the booster pipe, the telescopic pipe and the connecting head, and forces the plurality of float balloons to expand and become larger, thereby providing stable buoyancy support for the upper boom body and the lower skirt body on the sea surface. At the same time, the pressurized gas source in the plurality of float balloons also reaches the balancing float bag through a plurality of straight hoses, forcing the plurality of balancing float bags to expand and become larger, thereby further making the upper boom body and the lower skirt body float stably in the upper and lower areas of the sea surface, effectively preventing fire from intercepting the oil on the sea surface in the incident area, so as to prevent the sea breeze from overturning the upper boom body and the lower skirt body, resulting in oil spillage. At the same time, the upper boom body and the lower skirt body with a double design are adopted to take double fire-proof oil containment measures for the oil on the sea surface in the incident area, thereby further improving the fire-proof oil containment performance of the fire-proof oil boom.

[0023] 4. This offshore fire-proof oil boom, finally, the pressurized air source in several groups of float balloons is supplied to several groups of long sealing tubes, and forces several groups of long T-shaped rods, long return springs and upper brackets to drive the upper boom body located above the sea surface to expand upward, and the above-water extended portion of the upper boom body is provided with extension compensation by the upper telescopic body, effectively intercepting the oil fire on the sea surface and preventing it from spreading to other incident areas. At the same time, the pressurized air source in several groups of float balloons is also supplied to several groups of short sealing tubes, which also forces several groups of short T-shaped rods, short return springs and lower brackets to drive the lower skirt body located below the sea surface to expand downward, and the underwater extended portion of the lower skirt body is provided with extension compensation by the lower telescopic body, effectively containing the oil immersed below the sea water, and fully improving the fire-proof and oil-containment performance of the fire-proof oil boom.

[0047] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention.

Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0048] like Figures 1-17 As shown, a marine fire prevention oil pollution boom of the present invention includes a water rower 1, a fixing frame 2 is fixed obliquely on all four sides of the water rower 1, an electric steering rudder is provided on the front side of the water rower 1, a deflector is fixedly connected to the front side of the fixing frame 2, and the fixing frame 2 and the cylinder barrel 3 are distributed in a 45-degree inclined state along the longitudinal axis of the water rower 1, so that the fixing frame 2 and the cylinder barrel 3 are reasonably distributed and conform to aerodynamics, thereby reducing the rowing air resistance of the water rower 1, and the fixing frame 2 is connected to the cylinder barrel 3, and a streamlined air inlet is connected to the side of the water rower 1 close to the fixing frame 2, and a filter is embedded at the entrance of the streamlined air inlet to provide pure gas supply to the cylinder barrel 3;

[0049] The water rower 1 is provided with a rowing component 4 for dragging the oil boom forward, and the fixing frame 2 is provided with an inflation component 5 used in conjunction with the cylinder 3. The rear side of the water rower 1 is pulled with an oil boom with a double-layer design, and the inflation source of the oil boom is supplied by the inflation component 5. The upper and lower sides of the oil boom are provided with expansion components 7. Based on the high-power towing and rowing water rower, the flexible and easy-to-reel fire boom can be quickly deployed to the incident area. At the same time, the fire boom can also be stably inflated and expanded by real-time inflation supply, replacing the remote support of the deck air supply equipment, reducing costs, and preventing oil from drilling through the fire boom and spilling. The fire oil containment is more sufficient and more efficient.

[0050] like Figure 6-Figure 16As shown, the rowing assembly 4 includes a double-headed motor 41 fixed to the inner cavity of the water rower 1. The double-headed motor 41 first provides a unified driving source to save power costs, and the two output shafts of the double-headed motor 41 are fixedly connected to the main bevel gear 42, the outer side of the main bevel gear 42 is meshed with a sub-bevel gear 43, and the inner cavity of the sub-bevel gear 43 is fixedly connected to a rotating shaft 44 that rotates with the cavity of the water rower 1, and both sides of the rotating shaft 44 are fixedly connected to planetary bevel gears 45, and the bottom of the planetary bevel gear 45 is meshed with a differential bevel gear 46, and the meshing transmission of the main bevel gear 42 and the sub-bevel gear 43 is matched, and the variable speed is matched by the planetary bevel gear 45 on the rotating shaft 44 and the differential bevel gear 46;

[0051] The inner cavity of the differential bevel gear 46 is fixedly connected to a drive shaft 47 that rotates with the cavity of the water rower 1, and the bottom of the drive shaft 47 is fixedly connected to a propeller 48 used for the water rower 1 to row on the sea surface. The four drive shafts 47 drive the four sets of propellers 48 to rotate synchronously, providing driving force for the water rower 1, and the water rower 1 is used to quickly drag the fire boom to the incident area, so as to carry out fire prevention and oil containment operations on the sea surface of the incident area in the first time, which not only improves the deployment efficiency of the fire boom, but also prevents the oil pollution danger on the sea surface of the incident area from further expanding and spreading;

[0052] The bottom of the water rower 1 is fixedly connected to a spoiler 9 that rotates with the drive shaft 47, and the spoiler 9 is located on the outside of the propeller 48. The bottom of the spoiler 9 is provided with a spoiler port for the water intake of the propeller 48. While protecting the propeller 48, it also disturbs the water intake of the propeller 48, thereby improving the smoothness of the rotation of the propeller 48.

[0053] The inflatable assembly 5 includes a main synchronous wheel 51 fixed on both sides of the rotating shaft 44 near the auxiliary bevel gear 43, and the upper part of the main synchronous wheel 51 is connected to the auxiliary synchronous wheel 52 through a synchronous belt transmission. First, the main synchronous wheel 51 and the auxiliary synchronous wheel 52 on the rotating shaft 44 are synchronously driven. The inner cavity of the auxiliary synchronous wheel 52 is fixedly connected to a concave rod frame 53 that rotates with the fixed frame 2, and the center of the concave rod frame 53 is rotatably connected to a connecting rod 54 through a rotating sleeve. The other end of the connecting rod 54 is hinged to a piston 55 that slides with the cylinder barrel 3. The concave rod frame 53, the connecting rod 54 and the piston 55 realize reciprocating work in the cylinder barrel 3.

[0054] The exhaust port of the cylinder 3 is connected to a three-way valve 56, and the bottom end of the three-way valve 56 is connected to a supply pipe 57. The floating plates on both sides of the water rower 1 are provided with pressure storage chambers 58 that are connected and matched with the supply pipe 57. The pressurized air source generated in the cylinder 3 is then supplied to the pressure storage chambers 58 reserved in the floating plates on both sides of the water rower 1 through the supply pipe 57 on the three-way valve 56, providing a real-time supply measure for the subsequent deployment of the fire boom. There is no need for the air supply equipment on the ship deck to remotely supply the fire boom, which saves the cost of supply equipment and has a high air supply responsiveness.

[0055] A pressure sensor 10 is embedded in the top of the three-way valve 56 to monitor the pressure of the pressurized gas source flowing through the three-way valve 56 in real time to ensure that the pressure of the pressurized gas is sufficient to avoid insufficient air supply during the subsequent deployment of the fire-proof oil boom. The shape of the pressure storage chamber 58 is the same as that of the floating plates on both sides of the water rower 1, and it adopts a streamlined design that is easy to float on water, thereby improving the sea surface rowing performance of the water rower 1.

[0056] The oil containment assembly includes a boosting pipe 61 fixed to the rear side of the floating plates on both sides of the water rower 1 and connected to the pressure storage chamber 58. The rear end of the boosting pipe 61 is connected to a telescopic pipe 62. Both ends of the telescopic pipe 62 are connected to a connecting head 63, and the inner end of the connecting head 63 is connected to a float balloon 64. The boosting pipe 61, the telescopic pipe 62 and the connecting head 63 first supply the pressurized air source in the pressure storage chamber 58 to the multiple groups of float balloons 64, and force the multiple groups of float balloons 64 to expand and become larger, providing stable buoyancy support for the distribution of the upper rail body 67 and the lower skirt body 68 above and below the sea surface.

[0057] The inner end of the float balloon 64 is connected to a straight hose 65, and the inner end of the straight hose 65 is connected to a balancing float 66 used in conjunction with the float balloon 64. The upper and lower sides of the float balloon 64 are respectively wrapped with an upper fence 67 and a lower skirt 68 for fire-proof oil containment, and the water height of the upper fence 67 is greater than the underwater depth of the lower skirt 68. The upper fence 67 and the lower skirt 68 are made by sewing technology and sewing with high-temperature resistant metal wire sewing thread, which improves the overall retractability of the upper fence 67 and the lower skirt 68 while also improving its overall strength. At the same time, several groups of The pressurized air source in the float balloon 64 also reaches the balancing float 66 through several groups of straight hoses 65, forcing the several groups of balancing float 66 to expand and become larger, further making the upper boom 67 and the lower skirt 68 float stably in the upper and lower areas of the sea surface, effectively preventing the oil pollution on the sea surface in the incident area from being overturned by the sea breeze, thereby preventing the oil pollution from being spilled. At the same time, the double-designed upper boom 67 and lower skirt 68 are used to take double fire prevention and oil containment measures against the oil pollution on the sea surface in the incident area, further improving the fire prevention and oil containment performance of the fire-proof oil boom.

[0058] The float balloon 64 is wrapped with high-temperature resistant nano-aerogel felt 11 and alumina fiber felt 12 from the outside to the inside, which has fire and oil-proof effects on the float balloon 64 and improves the service life of the float balloon 64. At the same time, the high-temperature resistant nano-aerogel felt 11 and the alumina fiber felt 12 have the advantages of light weight and non-water absorption, which ensures the quality of the float balloon 64 while reducing the cost. The float balloon 64 located on the rear side is connected to the main pressure relief pipe 13, and the main pressure relief valve is provided on the main pressure relief pipe 13, which plays the role of pressure relief and resetting the fire boom after the fire boom is completed, which is conducive to the subsequent winding of the completed fire boom.

[0059] The boost pipe 61, the telescopic pipe 62 and the connecting head 63 are all connected by threads, which facilitates the rapid disassembly and connection of the boost pipe 61, the telescopic pipe 62 and the connecting head 63. The two connecting ends of the telescopic pipe 62 are fixedly connected to the elastic rope 14 that cooperates with the telescopic end to elastically stretch the telescopic pipe 62 and reduce the stress burden of the telescopic pipe 62. The upper rail 67 and the lower skirt 68 are fixedly connected to the float balloon 64 through the connecting splint 15 to ensure the stability of the connection between the upper rail 67 and the lower skirt 68 and the float balloon 64.

[0060] The outer end of the float balloon 64 is connected to the auxiliary pressure relief pipe 16, and the auxiliary pressure relief valve is provided on the auxiliary pressure relief valve, which plays the role of pressure relief and reset for the float balloon 64, the balancing float 66, the long sealing tube 71 and the short sealing tube 75 after the fire-proof oil containment is completed. An upper telescopic body 17 and a lower telescopic body 18 are respectively provided between the upper fence body 67 and the lower skirt body 68 to provide extension support for the adjustment of the upper fence body 67 and the lower skirt body 68. The upper telescopic body 17 and the lower telescopic body 18 are made of the same material as the upper fence body 67 and the lower skirt body 68. They are all made of high-temperature resistant metal wire mesh and high-temperature resistant alumina blanket. They can not only withstand high temperatures of 1200°C, but also withstand high temperatures for one day, and their long-term open flame combustion performance remains unchanged. The combination of the two can make the fire-proof oil containment boom have excellent performance, that is, fire resistance, wear resistance and tensile resistance, and play a fire and oil prevention role on the upper telescopic body 17 and the lower telescopic body 18 and the upper fence body 67 and the lower skirt body 68, thereby improving their service life.

[0061] The expansion assembly 7 includes a long sealing tube 71 connected to the top of the float balloon 64. The pressurized air source in several groups of float balloons 64 is supplied to several groups of long sealing tubes 71. The inner cavity of the long sealing tube 71 is slidably connected with a long T-shaped rod 72. The long T-shaped rod 72 is provided with a long return spring 73 fixedly matched with the long sealing tube 71. The top of the long T-shaped rod 72 is fixedly connected to an upper bracket 74 fixedly matched with the upper fence body 67, and forces the several groups of long T-shaped rods 72, the long return spring 73 and the upper bracket 74 to drive the upper fence body 67 above the sea surface to expand upward. The above-water extension part of the upper fence body 67 is provided with extension compensation by the upper telescopic body 17, which effectively intercepts the oil fire on the sea surface and prevents it from spreading to other incident areas.

[0062] The bottom of the float balloon 64 is connected to a short sealing tube 75, and the pressurized air source in several groups of float balloons 64 is also supplied to several groups of short sealing tubes 75, and the inner cavity of the short sealing tube 75 is slidably connected to a short T-shaped rod 76, and a short return spring 77 fixedly matched with the short sealing tube 75 is sleeved on the short T-shaped rod 76, and the bottom of the short T-shaped rod 76 is fixedly connected to a lower bracket 78 fixedly matched with the lower skirt 68, which also forces several groups of short T-shaped rods 76, short return springs 77 and lower bracket 78 to drive the lower skirt 68 below the sea surface to expand downward, and the underwater extension part of the lower skirt 68 is provided with extension compensation by the lower telescopic body 18, which effectively contains oil pollution immersed below the sea water, and fully improves the fire prevention and oil containment performance of the fire-proof oil boom.

[0063] like Figure 17 As shown, when the water rower 1 drags the fire boom on the sea surface, the fire boom needs to be rolled up and placed, and is designed with flexible materials, which causes the fire boom to swing violently or even overturn during the rowing on the sea surface, causing the oil on the sea surface in the incident area to spill through the overturned fire boom, and also easily causing the fire boom to be unevenly stressed and fall apart, which is not worth the loss. The rear side of the water rower 1 is provided with a stabilizing assembly that is smoothly deployed with the oil containment assembly and the expansion assembly 7. Component 8, and the stabilizing component 8 includes an upper telescopic sleeve 81 fixed to the top of the rear side of the water rower 1, and the other end of the upper telescopic sleeve 81 is fixedly connected to an upper belt body 82 fixedly provided with the upper bracket 74, and the inner cavities of the upper telescopic sleeve 81 and the upper belt body 82 are both penetrated by a steel wire rope 83 fixedly matched with the water rower 1, and the upper telescopic sleeve 81 and the upper belt body 82 are both flexible and retractable. The two steel wire ropes 83 are used to pull the upper fence 67 and the upper telescopic body 17 as a whole for overall stability;

[0064] The bottom of the rear side of the water rower 1 is fixedly connected with a lower telescopic sleeve 84, and the other end of the lower telescopic sleeve 84 is fixedly connected with a lower belt body 85 fixed with the lower bracket 78. The inner cavities of the lower telescopic sleeve 84 and the lower belt body 85 are both penetrated with a counterweight chain 86 fixedly matched with the water rower 1, and the rear sides of the upper belt body 82 and the lower belt body 85 are fixedly connected with a positioning reinforcement rope 19, which fixes the upper belt body 82 and the lower belt body 85 as well as the rear sides of the upper rail body 67 and the lower skirt body 68 as a whole. The lower telescopic sleeve 84 and the lower belt body 85 also adopt a flexible and retractable design, and are then connected by two counterweight chains. 86 acts as a counterweight for the lower skirt 68, making it easier for the lower skirt 68 to fall below the sea surface and intercept the oil pollution below the sea surface. At the same time, it also performs overall stabilization pulling treatment on the lower skirt 68 and the lower telescopic body 18, thereby improving the overall stability of the fire boom during the dragging and rowing on the sea surface. At the same time, it also improves the force uniformity of the fire boom, so as to prevent the fire boom from being damaged due to uneven force, reduce the maintenance frequency of the fire boom, and avoid the fire boom from being too soft and tipping over, thereby further improving the effective fire prevention and oil containment performance of the fire boom against oil pollution above and below the sea surface in the incident area.

[0065] The working principle of a marine fire prevention oil pollution boom is as follows: first, two positioning reinforcement ropes 19 are fixed on the deck of the ship, and then the double-headed motor 41 in the water rower 1 is controlled to start and drive the two sets of main bevel gears 42 to rotate synchronously. The two sets of main bevel gears 42 drive the rotating shafts 44 on the two sets of auxiliary bevel gears 43 to rotate accordingly. The planetary bevel gears 45 on the two rotating shafts 44 then drive the four sets of differential bevel gears 46 to rotate accordingly. The four sets of differential bevel gears 46 drive the propellers 48 on the four drive shafts 47 to rotate inside the four sets of spoilers 9. Providing power support for the water rower 1 to row on the sea surface, the water rower 1 rowing on the sea surface drags the fire boom toward the incident area. Under the fixed support provided by the two positioning reinforcement ropes 19 to the rear sides of the multiple groups of upper booms 67 and lower skirts 68, after the water rower 1 drags the fire boom to the sea surface of the incident area, the multiple groups of upper booms 67 and lower skirts 68 composed of high-temperature resistant metal wire mesh and high-temperature resistant alumina blanket are also deployed and stretched around the oil pollution area on the sea surface where the incident occurred.

[0066] During the period when the water rower 1 is fully stretching out the double groups of upper fences 67 and lower skirts 68 around the oil pollution area on the sea surface where the incident occurred, the two upper telescopic sleeves 81 and the upper belt body 82 fixed on the top of the rear side of the water rower 1 provide flexible protection for the two steel wire ropes 83, and then the two steel wire ropes 83 are used to pull and fix the groups of upper fences 67 as a whole, so that the groups of upper fences 67 remain in a stable state during the rowing and deployment on the sea surface. At the same time, the upper fences 67 fixed on the water rower 1 are fixed to the upper belt body 82. Under the condition that the two lower telescopic sleeves 84 and the lower belt body 85 at the rear bottom of the device 1 provide flexible protection for the two counterweight chains 86, the two counterweight chains 86 counterweight the multiple sets of lower skirts 68, forcing the multiple sets of lower skirts 68 to fall below the sea surface. Then, the multiple sets of lower skirts 68 maintain a stable deployment state during the deployment under the sea surface, so that the multiple sets of upper rails 67 and lower skirts 68 can be deployed in a stable manner to fully prevent fire and contain oil above the sea surface and oil pollution below the sea surface;

[0067] The two rotating shafts 44 synchronously drive the four sets of main synchronous wheels 51 to rotate, and the four sets of main synchronous wheels 51 drive the four sets of auxiliary synchronous wheels 52 to rotate synchronously through four synchronous belts. The four sets of auxiliary synchronous wheels 52 drive the four concave rod racks 53 to rotate accordingly. The four concave rod racks 53 drive the pistons 55 on the four connecting rods 54 through the four sets of rotating sleeves to perform reciprocating work in the four sets of cylinder barrels 3, and generate pressurized gas in the four sets of cylinder barrels 3. The pressurized gas in the four sets of cylinder barrels 3 is supplied to the pressure storage chambers 58 reserved in the floating plates on both sides of the water rower 1 through two sets of three-way valves 56 in the open state through two supply pipes 57. The pressure of the pressurized gas flowing through is monitored in real time by the pressure sensors 10 on the two sets of three-way valves 56, and the pressurized gas source is supplied to the two sets of pressure storage chambers 58 for temporary storage.

[0068] When the water rower 1 opens several groups of upper rails 67 and lower skirts 68, the pressurized air source in the two groups of pressure storage chambers 58 is also supplied to several groups of float balloons 64 through two booster pipes 61 through several telescopic pipes 62 and connecting heads 63 in sequence. Since the several groups of float balloons 64 are provided with high-temperature resistant nano-aerogel felt 11 and alumina fiber felt 12 flexible protective layers, the float balloons 64 are protected from oil contamination and flame combustion, forcing the several groups of float balloons 64 to expand rapidly, providing buoyancy support for the opened several groups of upper rails 67 and lower skirts 68 on the sea surface. At the same time, the pressurized gas entering the plurality of groups of float balloons 64 also passes through the plurality of straight hoses 65 and reaches the plurality of groups of balancing floats 66, which also forces the plurality of groups of balancing floats 66 to expand rapidly, further providing support points above and below the sea surface for the double upper rails 67 and lower skirts 68, so that the plurality of groups of upper rails 67 and lower skirts 68 on the connecting splints 15 can float stably above and below the sea surface. The upper rails 67 and lower skirts 68, which are composed of a composite of a high-temperature resistant metal wire mesh and a high-temperature resistant alumina blanket, can respectively block the fire of the oil pollution on the sea surface and block the oil pollution that penetrates below the sea surface.

[0069] At the same time, the pressurized gas that reaches several groups of float balloons 64 is also supplied to several groups of long sealing cylinders 71 and short sealing cylinders 75. As the pressurized gas source is continuously supplied, the pressure in several groups of long sealing cylinders 71 and short sealing cylinders 75 increases sharply. Under the action of the pressure, the long T-shaped rods 72 in several groups of long sealing cylinders 71 are forced to push upward and compress several long return springs 73. The upward-pushing several long T-shaped rods 72 drive the upper fence 67 above the sea surface to move upward through the upper bracket 74, and drive the upper telescopic body 17 between the upper fence 67 to extend upward, so that the raised upper fence 67 further increases the resistance to the oil fire on the sea surface. Similarly, the pressure of the pressurized gas supplied into several groups of short sealing cylinders 75 also forces several short T-shaped rods 76 to move downward and compress several short return springs 77. The several short T-shaped rods 76 moving downward drive the lower skirt 68 below the sea surface to continue to move downward through the lower bracket 78, and drive the lower telescopic body 18 between the lower skirt 68 to extend downward, extending the depth of the lower skirt 68 below the sea surface, and effectively blocking the oil pollution immersed below the sea surface. The upper fence 67 and the lower skirt 68 composed of high-temperature resistant metal wire mesh and high-temperature resistant alumina blanket adopt a double design, which can effectively carry out fire prevention and oil containment treatment for fire and oil pollution above and below the sea surface.

[0070] It should be noted that the specific models and specifications of the double-headed motor 41, pressure sensor 10 and various valves need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
