Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to an offshore oil pollution cleaning vessel and an offshore oil pollution cleaning method. Background Art

[0002] With the growing demand for oil in countries around the world, the oil transportation industry has grown rapidly. However, with the increasing frequency of oil spill accidents in shipping, the situation of crude oil spills at sea has become more and more serious. The difficulty in cleaning up crude oil at sea is that when a serious oil spill occurs at sea, the leaked crude oil will spread into an oil film several millimeters thick at a very fast speed, moving around with the wind and waves at sea until it is transported to the shore by the sea breeze for further deposition. It is difficult for existing technologies to arrive at the sea area where the accident occurred in time after the accident and carry out emergency disposal at the accident site. Therefore, the research problem about cleaning up crude oil at sea is: how to efficiently clean up the large area of ​​oil film caused by crude oil spills and minimize the losses caused by crude oil spills. At present, the most widely used method of collecting and treating oil pollution at sea is to use oil booms to contain it, which is highly practical and effective. However, this method is often not efficient enough to deal with large-scale floating oil films at sea. The collection and cleaning of floating oil at sea still requires manpower. This inefficient way of cleaning up crude oil at sea has undoubtedly aggravated the serious consequences of crude oil spills. Summary of the invention

[0023] Please refer to Figure 1The present application provides a marine oil pollution cleaning ship 100. The marine oil pollution cleaning ship 100 includes a main hull 1, a split hull, a floating suction device 3, a control device 4 and an image recognition device 5. Among them, the main hull 1 can be a cabin for users to operate and control the cleaning ship 100, such as a cockpit. The split hull is provided with an oil collecting baffle 20. The split hull is connected to the main hull 1, and includes a first split hull 21 and a second split hull 22. The first split hull 21 and the second split hull 22 are arranged side by side on one side of the main hull 1. The first split hull 21 and the second split hull 22 are arranged oppositely, and can be relatively separated or merged from the front end away from the main hull 1 in an operable manner. The floating suction device 3 includes a first floating suction device and a second floating suction device. The first floating suction device is arranged on the inner side of the first split hull 21. The second floating suction device is arranged on the inner side of the second split hull 22. The control device 4 can be a control component arranged on the main hull 1, such as a control console arranged in the cockpit. The control device 4 is used to control the separation of the split and combined hulls to form an oil-enclosed area when the distance from the target area is within a preset range, and to control the oil collecting baffle 20 to extend to surround the oil-enclosed area together with the split and combined hulls. The image recognition device 5 includes an infrared camera 51 and a color camera 52. The image recognition device 5 is used to identify the oil pollution area in the oil-enclosed area. In order to improve the effect of the image recognition device 5 in identifying the oil pollution area, the image recognition device 5 can be arranged on the side of the main hull 1 close to the split and combined hull. When the oil pollution area in the oil-enclosed area reaches a preset area, the control device 4 controls the oil collecting baffle 20 to move from the side close to the front end of the main hull 1 to the main hull 1 to squeeze the oil pollution in the oil-enclosed area and increase the thickness of the oil pollution in the oil-enclosed area, so as to facilitate the suction of the oil pollution by the floating suction device 3. In the present application, the first split and combined hull 21 and the second split and combined hull 22 can be the same or different split and combined hulls. Optionally, the first split-and-combined hull 21 and the second split-and-combined hull 22 are identical split-and-combined hulls, and the first split-and-combined hull 21 and the second split-and-combined hull 22 are symmetrically arranged about the main hull 1. The specific features of each component in the cleaning ship 100 will be described in detail below.

[0024] In this embodiment, the first split-and-combined hull 21 and the second split-and-combined hull 22 are both provided with a connecting rod 210. The main hull 1 is rotatably connected to the connecting rod 210 through a rotating mechanical arm, so as to be rotatably connected to the first split-and-combined hull 21 and the second split-and-combined hull 22 respectively. Among them, the rotating mechanical arm includes a first rotating mechanical arm 211 and a second rotating mechanical arm 221. The connecting rod 210 includes a first connecting rod provided on the first split-and-combined hull 21, and a second connecting rod provided on the second split-and-combined hull 22. The first rotating mechanical arm 211 is rotatably connected between the first connecting rod and the main hull 1, and the second rotating mechanical arm 221 is rotatably connected between the second connecting rod and the main hull 1. In one embodiment of the present application, the first rotating mechanical arm 211 is provided on the side of the first split-and-combined hull 21 away from the first floating suction device, and is located between the first connecting rod and the main hull 1. The second rotating mechanical arm 221 is provided on the side of the second split-and-combined hull 22 away from the second floating suction device, and is located between the second connecting rod and the main hull 1.

[0025] The first rotating mechanical arm 211 and the second rotating mechanical arm 221 can be the same or different rotating mechanical arms. In this embodiment, the first rotating mechanical arm 211 and the second rotating mechanical arm 221 are the same rotating mechanical arms. The first rotating mechanical arm 211 and the second rotating mechanical arm 221 both include a first motor, a base 2112 and a connecting arm 2113. Among them, the first motor of the first rotating mechanical arm 211 is arranged on the first split-and-combined hull 21, and the first motor of the second rotating mechanical arm 221 is arranged on the second split-and-combined hull 22. The two first motors are respectively provided with transmission rods 2111. The base 2112 of the first rotating mechanical arm 211 is arranged on the main hull 1, and the base 2112 of the second rotating mechanical arm 221 is arranged on the main hull 1. The connecting arm 2113 of the first rotating mechanical arm 211 is pivoted between the base 2112 of the first rotating mechanical arm 211 and one end of the transmission rod 2111, and the connecting arm 2113 of the second rotating mechanical arm 221 is pivoted between the base 2112 of the second rotating mechanical arm 221 and one end of the transmission rod 2111. The other end of the transmission rod 2111 of the first rotating mechanical arm 211 is rotationally connected to the connecting rod 210 of the first split-and-combined hull 21, i.e., the first connecting rod, through the connecting hole 2114. The other end of the transmission rod 2111 of the second rotating mechanical arm 221 is rotationally connected to the connecting rod 210 of the second split-and-combined hull 22, i.e., the second connecting rod, through the connecting hole 2114. The control device 4 controls the two first motors to respectively drive the connecting arm 2113 of the first rotating mechanical arm 211 and the connecting arm 2113 of the second rotating mechanical arm 221 to rotate around the base 2112, thereby respectively driving the front ends of the first split-and-combined hull 21 and the second split-and-combined hull 22 to rotate.

[0026] It can be understood that the control device 4 can control the first rotating mechanical arm 211 and the second rotating mechanical arm 221 to rotate respectively to drive the first split-and-combined hull 21 and the second split-and-combined hull 22 to rotate respectively. The control device 4 can independently adjust the rotation angle of the first split-and-combined hull 21 and the second split-and-combined hull 22 by controlling each first motor respectively, so as to adjust the size of the oil-enclosed area. Therefore, the rotation direction and rotation angle of the first split-and-combined hull 21 and the second split-and-combined hull 22 can be the same or different. In the process of forming the oil-enclosed area, when the cleaning ship 100 is sailing, the corresponding split-and-combined hull can be driven to rotate by each rotating mechanical arm, or when the cleaning ship 100 sails to a designated position within a preset range from the target area and stops sailing, the corresponding split-and-combined hull can be driven to rotate by each rotating mechanical arm. In one embodiment of the present application, the oil-enclosed area is the area formed when the rotation angles of the first split-and-combined hull 21 and the second split-and-combined hull 22 reach the maximum rotation angle respectively.

[0027] In this embodiment, the oil collecting baffle 20 includes a first oil collecting baffle and a second oil collecting baffle. The first oil collecting baffle is arranged between the first floating suction device and the front end of the first split-and-combined hull 21. The second oil collecting baffle is arranged between the front ends of the second floating suction device and the second split-and-combined hull 22. The first oil collecting baffle and the second oil collecting baffle are arranged opposite to each other. The oil collecting baffle 20 can be controlled by the control device 4 to move.

[0028] The first oil collecting baffle and the second oil collecting baffle can be the same or different oil collecting baffles. In this embodiment, the first oil collecting baffle and the second oil collecting baffle are the same oil collecting baffles. The first oil collecting baffle and the second oil collecting baffle both include a second motor 2031, a first driving rod 2032, a second driving rod 2033 and a third driving rod 2034. Among them, the first driving rod 2032 and the second driving rod 2033 of the first oil collecting baffle are respectively connected between the second motor 2031 of the first oil collecting baffle and the first oil collecting baffle along the extension direction of the first oil collecting baffle, and the third driving rod 2034 of the first oil collecting baffle is connected between the second motor 2031 of the first oil collecting baffle and the top of the first oil collecting baffle. The first driving rod 2032 and the second driving rod 2033 of the second oil collecting baffle are respectively connected between the second motor 2031 of the second oil collecting baffle and the second oil collecting baffle along the extension direction of the second oil collecting baffle, and the third driving rod 2034 of the second oil collecting baffle is connected between the second motor 2031 of the second oil collecting baffle and the top of the second oil collecting baffle. The control device 4 is respectively connected to the two second motors 2031. The control device 4 controls the first oil collecting baffle to extend toward the second splitting and combining hull 22 along the first driving rod 2032 and the second driving rod 2033 of the first oil collecting baffle, and controls the second oil collecting baffle to extend toward the first splitting and combining hull 21 along the first driving rod 2032 and the second driving rod 2033 of the second oil collecting baffle, so that the first oil collecting baffle and the second oil collecting baffle and the splitting and combining hull jointly surround the oil confinement area, thereby limiting the oil pollution in the oil confinement area.

[0029] Further, the first oil collecting baffle and the second oil collecting baffle both include an oil boom 201 and a telescopic member 202. The telescopic member 202 of the first oil collecting baffle can be telescopically mounted on the oil boom 201 of the first oil collecting baffle to extend to the bottom of the oil boom 201 of the first oil collecting baffle or to be retracted into the oil boom 201 of the first oil collecting baffle. The telescopic member 202 of the second oil collecting baffle can be telescopically mounted on the oil boom 201 of the second oil collecting baffle to extend to the bottom of the oil boom 201 of the second oil collecting baffle or to be retracted into the oil boom 201 of the second oil collecting baffle. After the first oil collecting baffle and the second oil collecting baffle are respectively extended from the first split-and-combined hull 21 and the second split-and-combined hull 22, the control device 4 controls the two second motors 2031 respectively to drive the third driving rod 2034 of the first oil collecting baffle to drive the telescopic member 202 to extend from the oil boom 201 and extend below the sea surface, and drives the third driving rod 2034 of the second oil collecting baffle to drive the telescopic member 202 to extend from the oil boom 201 and extend below the sea surface, thereby stabilizing the oil boom 201 floating on the sea surface.

[0030] The first floating suction device and the second floating suction device can be the same or different floating suction devices. In this embodiment, the first floating suction device and the second floating suction device are the same floating suction device. The first floating suction device and the second floating suction device both include a plurality of floating suction boxes 32. Each floating suction box 32 of the first floating suction device is provided with a box wall extending from the floating suction box 32, and each floating suction box 32 of the second floating suction device is provided with a box wall extending from the floating suction box 32. When the control device 4 controls the first oil collecting baffle and the second oil collecting baffle to move toward the main hull 1, the box wall of the floating suction box 32 in the first floating suction device limits the first oil collecting baffle to move only between the first floating suction device and the front end of the first separation and combination hull 21, and the box wall of the floating suction box 32 in the second floating suction device limits the second oil collecting baffle to move only between the second floating suction device and the front end of the second separation and combination hull 22, so that the squeezed oil can be concentrated in the oil confinement area relative to the floating suction device 3, so as to avoid the oil in the oil confinement area from being excessively squeezed by the oil collecting baffle 20 and escaping from the oil confinement area, thereby improving the efficiency of oil cleaning.

[0031] Further, the first floating suction device and the second floating suction device each include a suction pump 31 and a plurality of floating suction components 33. Among them, the plurality of floating suction components 33 of the first floating suction device are accommodated in a plurality of floating suction boxes 32 of the first floating suction device, and the plurality of floating suction components 33 of the second floating suction device are accommodated in a plurality of floating suction boxes 32 of the second floating suction device. Each box wall is provided with a plurality of floating balls 30 for providing buoyancy. The plurality of floating balls 30 drive the floating suction boxes 32 to float on the sea surface, so that the plurality of floating suction components 33 of the first floating suction device and the second floating suction device are at a height roughly flush with the oil pollution. The suction pump 31 is connected to each floating suction component 33 respectively. The control device 4 controls the suction pump 31 to drive each floating suction component 33 to suck the oil pollution in the oil confinement area. Specifically, the suction pump 31 vacuumizes the plurality of floating suction components 33, so that a pressure difference is generated between the side of the floating suction component 33 close to the suction pump 31 and the side close to the oil confinement area. Since the oil stains float on the seawater and the oil collecting baffle 20 moves toward the main hull 1 to increase the thickness of the oil stains, the plurality of floating suction components 33 can fully absorb the oil stains only through a small pressure difference.

[0032] Furthermore, each floating suction assembly 33 includes a vacuum suction pipe 331, a vacuum housing 332, a flange 333 and a floating ring 334. The vacuum suction pipe 331 is connected to the suction pump 31. The flange 333 is connected between the vacuum suction pipe 331 and the vacuum housing 332 to improve the airtightness between the vacuum suction pipe 331 and the vacuum housing 332. The floating ring 334 surrounds the side of the vacuum housing 332 away from the vacuum suction pipe 331.

[0033] In this embodiment, the cleaning ship 100 also includes an oil pollution treatment device 6. The first floating suction device and the second floating suction device are respectively connected to the oil pollution treatment device 6 through the floating pipe 34 to transport the oil pollution sucked by the floating pipe 34 to the oil pollution treatment device 6. The oil pollution treatment device 6 includes an oil storage tank 61, an oil quantity sensor 62, a plurality of discharge pipes 63 and a delivery pipe 64. Among them, the oil quantity sensor 62 can distinguish between oil pollution and other substances sucked into the oil storage tank 61 by identifying whether the sensed substance is oil pollution, such as seawater. The oil quantity sensor 62 is used to sense the oil level in the oil storage tank 61. The control device 4 can control the process of cleaning the marine oil pollution by the cleaning ship 100 by controlling the opening or closing of the discharge pipe 63 and the delivery pipe 64. Specifically, each discharge pipe 63 is provided with a first valve 630. When the oil level reaches the first preset height, the control device 4 controls the first valve 630 to open to discharge the seawater separated from the oil pollution in the oil storage tank 61 through the discharge pipe 63. The delivery pipe 64 is connected between the oil storage tank 61 and the floating pipe 34. The delivery pipe 64 is provided with a second valve 640. When the oil level reaches a second preset height, the control device 4 controls the second valve 640 to close and controls the suction pump 31 to stop working. The second preset height is greater than the first preset height.

[0034] In the above embodiment, the specific features of the offshore oil pollution cleaning ship 100 are described. The offshore oil pollution cleaning ship 100 controls the first split hull 21 and the second split hull 22 to separate relatively through the control device 4 to increase the area where the cleaning ship 100 cleans the offshore oil pollution, and controls the oil collecting baffle 20 to move relative to the oil confining area to increase the thickness of the oil pollution in the oil confining area, so as to facilitate the floating suction device 3 to clean the oil pollution.

[0035] Please see Fig. 9 and Fig.10 The present application also provides a method for cleaning up marine oil pollution. The cleaning method is applied to a marine oil pollution cleaning ship 100. The marine oil pollution cleaning ship 100 has been described in detail above and will not be described again here. The cleaning method includes steps S101-S103.

[0036] Step S101, when the distance from the target area is within a preset range, the first split-and-combined hull and the second split-and-combined hull are controlled to separate relatively to form an oil-enclosed area, and the oil collecting baffle is controlled to extend to surround the oil-enclosed area together with the split-and-combined hull.

[0037] In step S101, the user controls the rotating mechanical arm of each split-and-combined hull to drive the corresponding split-and-combined hull to rotate around the main hull 1 through the control device 4 provided on the main hull 1 when the cleaning ship 100 sails to a preset range from the target area, so that the first split-and-combined hull 21 and the second split-and-combined hull 22 are relatively separated to form an oil-enclosed area. In one embodiment of the present application, when the rotation angles of the first split-and-combined hull 21 and the second split-and-combined hull 22 are controlled by the control device 4 to reach the maximum rotation angle respectively, the corresponding rotating mechanical arm is controlled to stop rotating. After the first split-and-combined hull 21 and the second split-and-combined hull 22 rotate to form an oil-enclosed area, the user controls the second motors 2031 of the first split-and-combined hull 21 and the second split-and-combined hull 22 to drive the first oil-collecting baffle and the second oil-collecting baffle to move relative to each other, so as to surround the oil-enclosed area together with the split-and-combined hull.

[0038] Step S102, when it is identified that the oil pollution area in the oil confining area reaches a preset area, the oil collecting baffle is controlled to move from a side close to the front end of the main hull toward the main hull.

[0039] In step S102, the image recognition device 5 is pre-trained with an image recognition model. The image recognition model is used to identify the relative area ratio of the oil pollution image in the sea surface image captured by the infrared camera 51 and the color camera 52, so as to determine the oil pollution area in the oil confinement area, and then determine whether the oil pollution formed by the oil collecting baffle 20 at sea is sufficiently concentrated. To ensure that the infrared camera 51 and the color camera 52 are sufficient to capture any oil confinement area, the field of view of the infrared camera 51 and the color camera 52 at least covers the oil confinement area formed when the first separation and combination hull 21 and the second separation and combination hull 22 are rotated to the maximum rotation angle. The image recognition model can be trained by feeding the images or historical images corresponding to the infrared camera 51 and the color camera 52 respectively through the initial training model. The initial training model can be an existing neural network model.

[0040] In order to improve the subsequent suction of oil pollution, the size of the oil-enclosed area can be adjusted by the first oil-collecting baffle and the second oil-collecting baffle to further increase the thickness of the oil pollution in the oil-enclosed area. Therefore, after the image recognition device 5 recognizes that the oil pollution area reaches the preset area, the user can control the oil-collecting baffle 20 to move toward the main hull 1 by controlling the second motor 2031 to adjust the thickness of the oil pollution in the oil-enclosed area. When each oil-collecting baffle 20 moves to a preset distance from the wall of the floating suction box 32 in the floating suction device 3 provided in the split-and-combined hull where it is located, the user can control each oil-collecting baffle 20 to stop moving.

[0041] Step S103, controlling the floating suction device to suck the oil in the oil confined area.

[0042] In step S103, after controlling the oil collecting baffle 20 to stop moving toward the main hull 1, the user can control the suction pump 31 to be in operation, so as to absorb the oil into the oil storage tank 61 of the oil treatment device 6 through the several floating suction components 33 connected to the suction pump 31 to complete the preliminary treatment of the oil pollution at sea. At this time, the oil pollution in the oil storage tank 61 is still mixed with seawater sucked together with the oil pollution. The oil pollution and the seawater can be gradually separated in the oil storage tank 61 by sedimentation. When the oil level sensor 62 detects that the oil level in the oil storage tank 61 is lower than the second preset height, the second valve 640 of the delivery pipe 64 can be controlled to open, and the suction pump 31 can be controlled to continuously absorb the oil pollution and seawater mixture into the oil storage tank 61. When there is more oil and seawater inside the oil storage tank 61 and the oil level reaches the first preset height, the discharge pipe 63 can release the bottom seawater by controlling the first valve 630 of the discharge pipe 63 to open. At this time, the oil level sensor 62 can detect the oil level of the discharge pipe 63 in real time when discharging seawater to control the first valve 630 of the discharge pipe 63 to close, so as to end the discharge of seawater in the oil storage tank 61. When the oil-seawater mixture gradually fills the oil storage tank 61 and the oil level reaches the second preset height, the second valve 640 of the delivery pipe 64 can be controlled to close, and the suction pump 31 can be controlled to stop working to stop the cleaning ship 100 from cleaning the marine oil pollution.

[0043] In this embodiment, the oil collecting baffle 20 includes a first oil collecting baffle and a second oil collecting baffle. The first oil collecting baffle and the second oil collecting baffle each include an oil boom 201 and a telescopic member 202. The telescopic member 202 is telescopically mounted on the oil boom 201 to extend below the oil boom 201 or retract into the oil boom 201. Before the oil collecting baffle is controlled to move from a side close to the front end of the main hull toward the main hull, the cleaning method further includes steps S201-S202.

[0044] Step S201, controlling the first oil collecting baffle to extend toward the second split-and-joint hull, and controlling the second oil collecting baffle to extend toward the first split-and-joint hull.

[0045] Step S202, controlling the telescopic member to extend from the oil boom to below the sea surface.

[0046] In some feasible embodiments, when the cleaning ship 100 sails in any sailing direction, the field of view of the infrared camera 51 and the color camera 52 can cover the surroundings of the cleaning ship 100. Before controlling the rotating mechanical arm of each split and combined hull to drive the corresponding split and combined hull to rotate, the method for cleaning oil pollution at sea also includes the following steps: controlling the image recognition device 5 to recognize the surroundings of the cleaning ship 100 to determine whether there is an oil pollution leakage at sea; when the image recognition device 5 determines that there is an oil pollution leakage at sea, the image obtained by the infrared camera 51 and the color camera 52 is used to output the oil pollution leakage direction relative to the current sailing direction of the cleaning ship 100, so as to control the cleaning ship 100 to sail in the direction of the oil pollution leakage.

[0047] In the above embodiment, the size of the area surrounded by the marine oil pollution by the cleaning ship is increased by using the first and second split-and-combined hulls that can be relatively separated or relatively combined, and the thickness of the oil pollution in the oil pollution area is increased by controlling the oil collecting baffle to move toward the main hull, and the vacuum flotation technology is combined to absorb the thickened oil pollution and separate the absorbed oil pollution from the seawater therein, thereby improving the cleaning efficiency of the marine oil pollution.
