After an offshore oil spill occurs, since oil booms can promptly and effectively control the oil spill without causing additional pollution, the use of oil booms to contain the oil spill is a common method used internationally. Offshore oil spills are often accompanied by fire accidents. In order to effectively contain the burning oil spill, fireproof oil booms are needed.

[0003] In the prior art (publication number CN109736277B, patent name is a patent application for a marine rapid sewage suction device and its sewage suction fence and sewage suction fence system), the recovery effect is good, the efficiency is high, the structure is simple, and the degree of automation is high.

This offshore fire-proof oil boom, then, firstly cooperates with the synchronous transmission of the main synchronous wheel and the auxiliary synchronous wheel on the rotating shaft, and the concave rod frame, the connecting rod and the 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, so as to provide real-time supply measures for the subsequent deployment of the fire-proof oil boom, and there is no need for the air supply equipment on the deck of the ship to remotely supply the fire-proof oil boom, which saves the cost of the supply equipment and has a high air supply responsiveness.

[0022] 3. The offshore fireproof oil pollution containment boom, then, firstly, the pressurized gas source in the pressure storage chamber is supplied into a plurality of groups of float balloons by the booster pipe, the telescopic pipe and the connecting head, and the plurality of groups of float balloons are forced to expand and become larger, so as to provide stable buoyancy support for the upper fence body and the lower skirt body to be distributed above and below the sea surface. At the same time, the pressurized gas source in the plurality of groups of float balloons also reaches the balance float through a plurality of groups of straight hoses, so as to force a plurality of groups of balance float balloons to expand and become larger, so as to further make the upper fence body and the lower skirt body float stably above and below the sea surface, and effectively intercept the oil pollution on the sea surface in the incident area from fire prevention, so as to prevent the sea breeze from overturning the upper fence body and the lower skirt body, resulting in the spillage of oil pollution. At the same time, the upper fence body and the lower skirt body with double design are adopted to take double fireproof oil containment measures for the oil pollution on the sea surface in the incident area, so as to further improve the fireproof oil containment performance of the fireproof oil containment boom;

[0023] 4. The offshore fireproof 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 reset springs and upper brackets to drive the upper boom body located above the sea surface to expand upward, and the above-water expansion part of the upper boom body is provided with extension compensation by the upper telescopic body, so as to effectively intercept the oil fire on the sea surface and prevent it from spreading to other incident areas.

[0050] like Figure 6-Figure 16As shown, the rowing assembly 4 includes a double-headed motor 41 fixed in the inner cavity of the water rower 1.

[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 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 real-time supply measures for the subsequent deployment of fire booms. There is no need for the air supply equipment on the deck of the ship to remotely supply the fire boom, saving the cost of supply equipment and having a high air supply responsiveness.

The upper fence 67 and the lower skirt 68 are made by sewing technology, and high-temperature resistant metal wire sewing thread is used for sewing, which improves the overall retractability of the upper fence 67 and the lower skirt 68, and also improves its overall strength. At the same time, several groups The pressurized air source in the float balloon 64 also reaches the balance float 66 through several groups of straight hoses 65, forcing several groups of balance float 66 to expand and become larger, further making the upper fence 67 and the lower skirt 68 stably float in the upper and lower areas of the sea surface, and effectively preventing the oil pollution on the sea surface in the incident area from being overturned by the sea breeze, causing the oil pollution to spill. At the same time, the upper fence 67 and the lower skirt 68 with double design are adopted to take double fire prevention and oil containment measures for 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 containment boom;

The upper rail body 67 and the lower skirt body 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 body 67 and the lower skirt body 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 arranged on the auxiliary pressure relief pipe 16, which plays the role of pressure relief and reset for the float balloon 64, the balance float 66, the long sealing tube 71 and the short sealing tube 75 after the fire-proof oil containment is completed.

[0063] like Fig.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 sway violently or even tip over during the rowing on the sea surface, causing the oil on the sea surface in the incident area to spill through the tipped fire boom, and also easily causing the fire boom to fall apart and be damaged due to uneven force, 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 6 and the expansion assembly 7. 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 82 which is fixedly provided with the upper bracket 74, and the inner cavities of the upper telescopic sleeve 81 and the upper belt 82 are both provided with a steel wire rope 83 which is fixedly matched with the water rower 1, and the upper telescopic sleeve 81 and the upper belt 82 are both designed to be flexible and retractable, and then the upper fence 67 and the upper telescopic body 17 are pulled and stabilized as a whole by two steel wire ropes 83;

[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 which is fixedly provided with the lower bracket 78. The inner cavities of the lower telescopic sleeve 84 and the lower belt body 85 are both provided with a counterweight chain 86 which is 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 then two counterweight chains are used. 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 below the sea surface. At the same time, the lower skirt 68 and the lower telescopic body 18 are also pulled and stabilized as a whole, thereby improving the overall stability of the fire boom during the dragging and rowing on the sea surface. At the same time, the force uniformity of the fire boom is also improved to prevent the fire boom from being damaged due to uneven force, thereby reducing the maintenance frequency of the fire boom and preventing 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 above and below the sea surface in the incident area.

[0065] The working principle of a marine fireproof oil pollution containment boom is as follows: first, two positioning reinforcement ropes 19 are fixed on the ship deck, and then the double-headed motor 41 in the water rower 1 is controlled to start and drive two sets of main bevel gears 42 to rotate synchronously, and 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, and the planetary bevel gears 45 on the two rotating shafts 44 then drive four sets of differential bevel gears 46 to rotate accordingly, and the four sets of differential bevel gears 46 drive the propellers 48 on the four drive shafts 47 to rotate in the four sets of spoilers 9. Providing power support for the water rower 1 to row on the sea surface, while the water rower 1 rowing on the sea surface drags the fire-proof oil boom toward the incident area. Under the fixed support provided by the two positioning reinforcement ropes 19 to the rear sides of the several groups of upper booms 67 and lower skirts 68, after the water rower 1 drags the fire-proof oil boom to the sea surface of the incident area, the several 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 pulled around the oil pollution area on the sea surface where the incident occurred;

[0066] During the period when the water rower 1 is fully pulling out the double groups of upper rails 67 and lower skirts 68 around the oil pollution area on the sea surface, the two upper telescopic sleeves 81 and upper belt bodies 82 fixed on the top of the rear side of the water rower 1 provide flexible protection for the two steel wires 83, and then the two steel wires 83 are used to pull and fix the groups of upper rails 67 as a whole, so that the groups of upper rails 67 are kept in a stable state during the rowing and deployment on the sea surface. At the same time, the upper rails 67 fixed on the water rower 1 are fixed to the upper belt bodies 82 and the upper belt bodies 82 are fixed to the upper belt bodies 82. Under the condition that the two lower telescopic sleeves 84 and the lower belt 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 several groups of lower skirts 68, forcing the several groups of lower skirts 68 to fall below the sea surface, and then keep the several groups of lower skirts 68 in a stable deployment state during the rowing and deployment under the sea surface, so that the several groups of upper railings 67 and lower skirts 68 can fully perform fire prevention and oil containment operations on the fire above the sea surface and the oil pollution below the sea surface in a stable deployment state;

[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, and the four sets of auxiliary synchronous wheels 52 drive the four concave rod racks 53 to rotate accordingly, and the four concave rod racks 53 drive the pistons 55 on the four connecting rods 54 through the four sets of rotating sleeves to reciprocate in the four sets of cylinder barrels 3, and generate pressurized gas in the four sets of cylinder barrels 3, and the pressurized gas in the four sets of cylinder barrels 3 is supplied to the reserved pressure storage chambers 58 in the floating plates on both sides of the water rower 1 through the two sets of three-way valves 56 in the open state through the two supply pipes 57, and 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 pressure storage chambers 58 is supplied to several groups of float balloons 64 through two booster pipes 61 in sequence through several telescopic pipes 62 and connecting heads 63. 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 pollution and flame burning, forcing the several groups of float balloons 64 to expand rapidly, thereby 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 that reaches the groups of float balloons 64 also reaches the groups of balance float bags 66 through the groups of straight hoses 65, which also forces the groups of balance float bags 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 groups of upper rails 67 and lower skirts 68 on the connecting splints 15 can stably float above and below the sea surface. The upper rails 67 and lower skirts 68 composed of the high-temperature resistant metal wire mesh and the high-temperature resistant alumina blanket can block the fire of the oil pollution on the sea surface and also block the oil pollution that penetrates below the sea surface.

[0069] At the same time, the pressurized gas that reaches the plurality of groups of float balloons 64 is also supplied to the plurality of groups of long sealing tubes 71 and short sealing tubes 75. With the continuous supply of the pressurized gas source, the pressure in the plurality of groups of long sealing tubes 71 and short sealing tubes 75 increases sharply. Under the action of the pressure, the long T-shaped rods 72 in the plurality of groups of long sealing tubes 71 are forced to push upward, and the plurality of long return springs 73 are compressed. The plurality of long T-shaped rods 72 that push upward drive the upper fence body 67 located above the sea surface to move upward through the upper bracket 74, and drive the upper telescopic body 17 between the upper fence body 67 to extend upward, so that the raised upper fence body 67 further increases the resistance to the fire of the oil pollution 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.
