Description

Technical Field

[0001] This utility model relates to the field of oil extraction, and more specifically to a shipwreck oil extraction system. Background Technology

[0002] The shipwreck oil pumping system is an operation that pumps out fuel oil, cargo oil, or liquid hazardous chemicals from a ship that has run aground or sunk, and transfers them to a safe vessel. It is an effective measure to prevent and mitigate the damage caused by oil spills and can reduce the likelihood of oil spill incidents.

[0003] In existing technologies, before oil extraction, it is usually necessary to open an oil extraction port at a predetermined location on the sunken ship, and then insert an oil extraction pipe into the port to extract the liquid. When the sunken ship is in a low-temperature environment, the fluidity of the liquid inside the ship will decrease, and it may even solidify, which will greatly reduce the efficiency of oil extraction.

[0004] On the other hand, in the existing technology, as the oil pumping operation proceeds, the liquid level will gradually decrease. When the liquid level is close to the bottom of the oil tank, a longer oil pumping pipeline is required to pump it out. The longer oil pumping pipeline will occupy more space on the ship and increase the difficulty of transportation. Utility Model Content

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0044] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled.

[0045] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0046] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] refer to Figures 1 to 12 This application provides a shipwreck oil extraction system 200, which includes an oil extraction mechanism 60, a heating mechanism 70, and a transfer box 80.

[0049] The oil pumping mechanism 60 includes an oil pumping pipe 61 and an oil pump 62. The first end of the oil pumping pipe 61 is connected to the oil pump 62, and the second end of the oil pumping pipe 61 is adapted to communicate with the oil storage tank 300 of the sunken ship.

[0050] The heating mechanism 70 includes a gas supply pipe 71 and a steam furnace 72. The first end of the gas supply pipe 71 is connected to the steam furnace 72, and the second end of the gas supply pipe 71 is adapted to be connected to the oil storage tank 300 for supplying water vapor into the oil storage tank 300.

[0051] The transfer box 80 has a receiving space 81 and an inlet 82, the inlet 82 being connected to the receiving space 81; the steam furnace 72 is installed in the receiving space 81, the steam furnace 72 includes a furnace body 721, a burner 722, an oil tank 723, and a water tank 724, the furnace body 721 has a combustion chamber 7211 and a water chamber 7212, the oil tank 723 is connected to the burner 722, the burner 722's nozzle extends into the combustion chamber 7211, the water tank 724 is connected to the water chamber 7212, and the first end of the gas supply pipe 71 is connected to the water chamber 7212. During operation, water in the water tank 724 can enter the water chamber 7212, fuel in the oil tank 723 can enter the burner 722, and the burner 722's nozzle sprays flames in the combustion chamber 7211 to heat the water in the water chamber 7212. The resulting water vapor enters the oil storage tank 300 through the gas supply pipe 71.

[0052] In the shipwreck oil extraction system 200 provided in this application, when the oil extraction mechanism 60 is used to extract fuel oil from the oil storage tank 300 of the shipwreck, the heating mechanism 70 can input high-temperature water vapor into the oil storage tank 300 to melt the fuel oil in the oil storage tank 300 during the oil extraction process, so that the oil extraction mechanism 60 can efficiently extract the fuel oil in the oil storage tank 300.

[0053] It should also be noted that the steam furnace 72 of the heating mechanism 70 is disposed within the receiving space 81 of the transfer box 80. Moving the transfer box 80 allows the position of the steam furnace 72 to be changed, facilitating its transport. For example, when steam needs to be introduced into the oil tank 300 of the sunken ship, the transfer box 80 is hoisted to the vicinity of the oil tank 300, and the steam furnace 72 is connected to the oil tank 300 via the gas supply pipe 71. After the fuel oil in the oil tank 300 is extracted, the transfer box 80 is moved away from the vicinity of the oil tank 300. Since the steam furnace 72 is installed within the receiving space 81 of the transfer box 80, only the transfer box 80 needs to be hoisted during the movement, making the transport process very convenient.

[0054] refer to Figure 1 and Figure 2 Furthermore, the sunken ship oil extraction system 200 further includes a water injection mechanism 90, which includes a water injection pipe 91 and a water injection pump 92. One end of the water injection pipe 91 is connected to the water injection pump 92, and the other end is adapted to be connected to the oil storage tank 300 of the sunken ship, for injecting water into the oil storage tank 300 during the oil extraction process.

[0055] When the oil pumping mechanism 60 is used to extract fuel from the oil storage tank 300, the fuel level in the oil storage tank 300 continuously decreases as the pumping operation proceeds. Water is injected into the oil storage tank 300 through the water injection mechanism 90. Since the density of fuel in the oil storage tank 300 is lower than that of water, as the amount of water injected into the oil storage tank 300 increases, the fuel level in the oil storage tank 300 will also continuously rise, thereby facilitating the oil pumping operation of the oil pumping mechanism 60.

[0056] Furthermore, the gas supply pipe 71 includes an inner gas supply pipe 711 and an outer gas supply pipe 712. One end of the inner gas supply pipe 711 is connected to the top of the water cavity 7212 of the furnace body 721, and the other end extends to the inlet 82 of the transfer box 80. One end of the outer gas supply pipe 712 is connected to the end of the inner gas supply pipe 711 located at the inlet 82, and the other end is adapted to be connected to the oil storage tank 300.

[0057] The connection point between the internal gas supply pipe 711 and the furnace body 721 is located at the top of the furnace body 721, facilitating the entry and exit of water vapor collected at the top of the water chamber 7212 into the internal gas supply pipe 711. One end of the internal gas supply pipe 711, away from the furnace body 721, extends to the inlet 82, facilitating connection with the external gas supply pipe 712. For example, during the transfer of the transfer box 80, the internal gas supply pipe 711 moves synchronously with the steam furnace 72. When the transfer box 80 is transferred to a suitable position, the external gas supply pipe 712 is connected to the internal gas supply pipe 711. Preferably, the end of the internal gas supply pipe 711 away from the furnace body 721 extends to the bottom area of ​​the inlet 82, that is, the end of the internal gas supply pipe 711 away from the furnace body 721 has a lower height, which makes it easier for the operator to connect the external gas supply pipe 712 to the internal gas supply pipe 711.

[0058] refer to Figure 3 and Figure 4 Specifically, the transfer box 80 has an open end 83 near the inlet 82 and a closed end 84 away from the inlet 82. The burner 722 and the oil tank 723 are disposed in the area of ​​the accommodating space 81 near the closed end 84. The burner 722 is disposed on the bottom wall of the transfer box 80, and the oil tank 723 is disposed on the side wall of the transfer box 80.

[0059] The oil tank 723 and the burner 722 are connected by a first connecting pipe 725. The oil tank 723 is disposed on the side wall of the transfer box 80, and the burner 722 is disposed on the bottom wall of the transfer box 80. The height of the oil tank 723 is higher than the height of the burner 722. The oil tank 723 is disposed on the side wall of the transfer box 80, which can make full use of the space above the burner 722 and improve the compactness of the structural arrangement of the steam furnace 72.

[0060] The water tank 724 is disposed in the area of ​​the accommodating space 81 near the closed end 84. The water tank 724 is disposed on the bottom wall of the transfer box 80 and located on one side of the furnace body 721. The water tank 724 and the water cavity 7212 of the furnace body 721 are connected by a second connecting pipe 726.

[0061] The sunken ship oil extraction system 200 further includes a flue pipe 73, one end of which is connected to the side of the combustion chamber 7211 away from the burner 722, and the other end extends to the inlet 82. The exhaust gas generated by the combustion of the burner 722 within the combustion chamber 7211 can be discharged through the flue pipe 73. The end of the flue pipe 73 away from the furnace body 721 extends to the inlet 82, facilitating the discharge of flue gas to the outside of the transfer box 80.

[0062] Furthermore, the heating mechanism 70 further includes a shielding cap 741 disposed at the end of the exhaust pipe 73 away from the furnace body 721 and a plurality of support rods 742. The bottoms of the plurality of support rods 742 are installed at the opening of the exhaust pipe 73 away from the furnace body 721, and the shielding cap 741 is disposed at the end of the plurality of support rods 742 away from the exhaust pipe 73. The shielding cap 741 can, to a certain extent, shield the opening of the exhaust pipe 73 away from the furnace body 721, preventing rainwater and other debris from entering the exhaust pipe 73.

[0063] refer to Figure 5 , Figure 6 as well as Figure 7 Furthermore, the transfer box 80 further includes a switch door 85 rotatably mounted on the open end 83. Rotating the switch door 85 controls the opening or closing of the inlet 82 at the open end 83. For example, rotating the switch door 85 closes the inlet 82 during the transfer of the transfer box 80, and rotating the switch door 85 opens the inlet 82 after the transfer box 80 has been transferred to a suitable position.

[0064] The top of the transfer box 80 is provided with a plurality of lifting lugs 86, each lug having a pre-set hole, allowing for easy repositioning of the transfer box 80. Preferably, there are four lifting lugs 86, each located in a different area on the top of the transfer box 80.

[0065] refer to Figures 8 to 12The sunken ship oil extraction system 200 further includes a connecting bracket 100, which is adapted to be installed on one side of the oil storage tank 300. The end of the oil extraction pipe 61 away from the oil extraction pump 62, the end of the gas supply pipe 71 away from the steam furnace 72, or the end of the water injection pipe 91 away from the water injection pump 92 is adapted to be installed on the connecting bracket 100 to communicate with the oil storage tank 300. Preferably, there are three connecting brackets 100, with one connecting bracket 100 installed at each end of the oil extraction pipe 61 away from the oil extraction pump 62, the gas supply pipe 71 away from the steam furnace 72, or the water injection pipe 91 away from the water injection pump 92.

[0066] The connecting bracket 100 includes a base plate 10 and a ball valve mechanism 20. The base plate 10 is adapted to be fixed to the outside of the oil tank 300 of the sunken ship, and the base plate 10 has a first opening 11 at a predetermined position. The ball valve mechanism 20 includes a valve housing 21 and a spherical valve core 22. The valve housing 21 has a first flow channel 210, the bottom of the valve housing 21 is mounted on the base plate 10, and the bottom opening of the first flow channel 210 communicates with the first opening 11; the valve housing 21 also has a rotating cavity 211 communicating with the first flow channel 210, the spherical valve core 22 is rotatably mounted in the rotating cavity 211, and the spherical valve core 22 has a second flow channel 220.

[0067] refer to Figure 11 The ball valve mechanism 20 has an open state and a closed state. In the open state, the center line of the second flow channel 220 coincides with the center line of the first flow channel 210, and the second flow channel 220 connects the first flow channel 210 located on the upper and lower sides of the ball valve core 22. When the ball valve mechanism 20 is in the open state, the drill bit of the drilling equipment can pass through the first flow channel 210, the second flow channel 220, and the first opening 11 to contact the outside of the oil tank 300 of the sunken ship for drilling operations.

[0068] refer to Figure 12In the closed state, the centerline of the second flow channel 220 intersects with the centerline of the first flow channel 210, and the spherical valve core 22 blocks the first flow channels 210 located on the upper and lower sides of the spherical valve core 22. Rotating the spherical valve core 22 relative to the valve housing 21 controls the ball valve mechanism 20 to switch between the open state and the closed state. When the ball valve mechanism 20 is in the closed state, the spherical valve core 22 blocks the first flow channels 210 located on the upper and lower sides of the spherical valve core 22. After the drilling operation is completed, switching the ball valve mechanism 20 to the closed state can seal the oil outlet hole opened on the outside of the oil tank 300 of the sunken ship, preventing oil leakage from the oil tank 300.

[0069] When using the connecting bracket 100 provided in this application, the base plate 10 is first fixedly installed on the outside of the oil tank 300 of the sunken ship. Then, the ball valve core 22 of the ball valve mechanism 20 is rotated to switch the ball valve mechanism 20 to the conducting state. Next, a drilling device is installed on the top of the connecting bracket 100, and the drill bit of the drilling device passes through the first flow channel 210, the second flow channel 220, and the first opening 11 to contact the outside of the oil tank 300 of the sunken ship for drilling. After drilling is completed, the drill head is pulled out from the first flow channel 210 and the second flow channel 220, and then the ball valve core 22 is rotated to switch the ball valve mechanism 20 to the closed state to prevent oil leakage from the oil tank 300.

[0070] The connecting bracket 100 provided in this application can provide a passage for the rotating head of the drilling equipment during the drilling process, prevent the drilling equipment from deviating, and improve the accuracy of the drilling position; after the drilling is completed, the ball valve mechanism 20 is switched to the closed state, which can seal the opened oil outlet and prevent oil leakage in the oil storage tank 300.

[0071] refer to Figure 8 and Figure 9Furthermore, the ball valve mechanism 20 further includes a first rotating rod 231 and a second rotating rod 232. The valve housing 21 has a rotation channel 212 at a preset position, which connects the rotation cavity 211 to the outside. One end of the first rotating rod 231 passes through the rotation channel 212 and connects to the spherical valve core 22. The other end of the first rotating rod 231 is connected to the second rotating rod 232, and the second rotating rod 232 and the first rotating rod 231 are staggered. One end of the first rotating rod 231 extending into the rotation cavity 211 is fixedly connected to the spherical valve core 22. Rotating the first rotating rod 231 can drive the spherical valve core 22 to rotate within the rotation cavity 211, thereby controlling the ball valve mechanism 20 to switch between the open state and the closed state. The end of the second rotating rod 231 away from the rotating cavity 211 is connected to the second rotating rod 232, and the first rotating rod 231 and the second rotating rod 232 are staggered. Rotating the second rotating rod 232 can drive the first rotating rod 231 to rotate, which facilitates the operator's operation.

[0072] It should be noted that the spherical valve core 22 is a sphere with the second flow channel 220, the rotating cavity 211 is a spherical cavity, and the radius of the rotating cavity 211 is adapted to the radius of the spherical valve core 22. The cross-sectional shape of both the first flow channel 210 and the second flow channel 220 in the direction perpendicular to the centerline is circular, and the radius of the first flow channel 210 is the same as the radius of the second flow channel 220. The radius of the spherical valve core 22 is larger than the radius of the first flow channel 210.

[0073] Furthermore, the bottom of the valve housing 21 is detachably connected to the base plate 10, and the valve housing 21 includes a first valve housing 213 and a second valve housing 214, which are detachably connected.

[0074] The valve housing 21 is detachably connected to the base plate 10. If either of them is damaged, they can be disassembled, and the damaged workpiece can be replaced, thus improving workpiece utilization. The first valve housing 213 and the second valve housing 214 are detachably connected to each other. This facilitates the placement of the spherical valve core 22 within the rotating cavity 211 and also allows for easy replacement of the spherical valve core 22 should it be damaged.

[0075] refer to Figure 8 and Figure 9Specifically, the bottom of the valve housing 21 has a first fixing lug 241 extending radially outward, and both the first fixing lug 241 and the base plate 10 have a plurality of first fixing holes 2410 at predetermined positions; the connecting bracket 100 further includes a first screw (not shown in the figure) installed in the first fixing hole 2410. In some embodiments, the inner wall of the first fixing hole 2410 has a thread adapted to the first screw, and the first screw is passed through the first fixing hole 2410 to fix the first fixing lug 241 to the base plate 10. In some embodiments, the first screw can also be replaced by a rivet. In some embodiments, the first fixing lug 241 can also be connected to the base plate 10 by welding, and when disassembly is required, a cutting tool can be used to cut along the connection to separate the two.

[0076] refer to Figure 9 Specifically, the first valve housing 213 has a plurality of first lugs 251 at predetermined positions, and the second valve housing 214 has a plurality of second lugs 252 at predetermined positions. When the first valve housing 213 and the second valve housing 214 are spliced ​​together, the first lugs 251 and the second lugs 252 are stacked on top of each other. The valve housing 21 has ear holes 250 penetrating the first lugs 251 and the second lugs 252. The connecting bracket 100 further includes a screw (not shown in the figure) installed in the ear hole 250. In some embodiments, the inner wall of the ear hole 250 has threads adapted to the screw, and the screw is passed through the ear hole to fix the first lugs 251 and the second lugs 252 together. In some embodiments, the screw can also be replaced by a rivet. In some embodiments, the first lugs 251 and the second lugs 252 can also be connected by welding, and when disassembly is required, a cutting tool can be used to cut along the connection to separate them.

[0077] refer to Figure 9 Furthermore, the connecting bracket 100 further includes a top plate 30, the top plate 30 having a second opening 31 at a preset position, the top plate 30 being mounted on the top of the valve housing 21, and the second opening 31 communicating with the top opening of the first flow channel 210.
