Description

Technical Field

[0001] This application relates to the field of cleaning technologies, and particularly to an offshore oil spill cleanup vessel and an offshore oil spill cleanup method. Background Art

[0002] With the increasing demand for oil in countries around the world, the oil transportation industry has grown rapidly. However, with the increasing frequency of shipping oil spill accidents, the situation of crude oil spills at sea has become increasingly serious. The difficulty in cleaning up crude oil at sea lies in that after a serious offshore crude oil leakage accident occurs, the leaked crude oil will quickly spread into an oil film several millimeters thick, moving around with the sea winds and waves until it is carried to the shore by the sea breeze for further deposition. It is very difficult for existing technologies to arrive at the accident area in time after the accident occurs and carry out emergency disposal at the accident site. Therefore, the research problem regarding offshore crude oil cleanup is: how to efficiently clean up the large-area oil film caused by crude oil leakage and minimize the losses brought by crude oil leakage.

[0003] At present, surrounding the offshore oil spill with an oil containment boom is the most widely used collection and treatment method, which has high practicability and good effects. However, when dealing with a large-area floating oil film at sea, the efficiency is often not satisfactory. The collection and cleanup of floating oil at sea still require manual labor, and this inefficient operation method for cleaning up crude oil at sea undoubtedly exacerbates the serious consequences brought by crude oil leakage. Summary of the Invention

[0004] This application provides an offshore oil spill cleanup vessel and an offshore oil spill cleanup method, which expand the area of the cleanup vessel surrounding the offshore oil spill through a separable hull and combine vacuum floating suction technology to improve the cleanup efficiency.

[0005] In a first aspect, an embodiment of the present application provides an offshore oil spill cleaning ship. The offshore oil spill cleaning ship includes a main hull, a separable and combinable hull, a floating suction device, a control device, and an image recognition device. The separable and combinable hull is connected to the main hull. The separable and combinable hull includes a first separable and combinable hull and a second separable and combinable hull arranged side by side. The first separable and combinable hull and the second separable and combinable hull can be operably separated or combined relatively at the front end away from the main hull. The separable and combinable hull is provided with an oil collecting baffle. The floating suction device includes a first floating suction device and a second floating suction device. The first floating suction device is arranged inside the first separable and combinable hull, and the second floating suction device is arranged inside the second separable and combinable hull. The first separable and combinable hull and the second separable and combinable hull are arranged oppositely. The control device is configured to control the separable and combinable hull to be separated relatively to form an oil containment area when at a preset range from the target area, and control the oil collecting baffle to extend to jointly enclose the oil containment area with the separable and combinable hull. The image recognition device is configured to identify the oil spill area within the oil containment area. When the oil spill area within the oil containment area reaches a preset area, the control device controls the oil collecting baffle to move from the side close to the front end of the main hull towards the main hull.

[0006] In a second aspect, an embodiment of the present application provides a method for cleaning offshore oil spills. The cleaning method is applied to the above-mentioned offshore oil spill cleaning ship. The cleaning method includes: when at a preset range from the target area, respectively controlling the first separable and combinable hull and the second separable and combinable hull to be separated relatively to form an oil containment area, and controlling the oil collecting baffle to extend to jointly enclose the oil containment area with the separable and combinable hull; when it is recognized that the oil spill area within the oil containment area reaches a preset area, controlling the oil collecting baffle to move from the side close to the front end of the main hull towards the main hull; controlling the floating suction device to suck the oil spills within the oil containment area.

[0007] For the above-mentioned offshore oil spill cleaning ship and the method for cleaning offshore oil spills, the first separable and combinable hull and the second separable and combinable hull that can be separated or combined relatively are used to increase the size of the area where the cleaning ship encloses the offshore oil spills, and by controlling the oil collecting baffle to move towards the main hull, the thickness of the oil spills within the oil spill area is increased, so as to combine with the vacuum floating suction technology to adsorb the thickened oil spills and separate the adsorbed oil spills from the seawater therein, thereby improving the cleaning efficiency of offshore oil spills.

[0024] Please refer to Figure 1, this application provides an offshore oil spill cleanup vessel 100. The offshore oil spill cleanup vessel 100 includes a main hull 1, a separable 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 the user to operate and control the cleanup vessel 100, such as a cockpit. The separable hull is provided with an oil collecting baffle 20. The separable hull is connected to the main hull 1 and includes a first separable hull 21 and a second separable hull 22. The first separable hull 21 and the second separable hull 22 are arranged side by side on one side of the main hull 1. The first separable hull 21 and the second separable hull 22 are oppositely arranged and can be operably separated or combined relatively from the front end far away from the main hull 1. The floating suction device 3 includes a first floating suction device and a second floating suction device. The first floating suction device is arranged inside the first separable hull 21. The second floating suction device is arranged inside the second separable 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 separable hull to relatively separate to form an oil containment area when it is within a preset range from the target area, and to control the oil collecting baffle 20 to extend to jointly surround the oil containment area with the separable hull. 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 spill area within the oil containment area. To improve the effect of the image recognition device 5 in recognizing the oil spill area, the image recognition device 5 can be arranged on the side of the main hull 1 close to the separable hull. When the oil spill area within the oil containment 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 towards the main hull 1 to squeeze the oil spill within the oil containment area and increase the thickness of the oil spill within the oil containment area, facilitating the suction of the oil spill by the floating suction device 3. In this application, the first separable hull 21 and the second separable hull 22 can be the same or different separable hulls. Optionally, the first separable hull 21 and the second separable hull 22 are the same separable hulls, and the first separable hull 21 and the second separable hull 22 are symmetrically arranged with respect to the main hull 1. The specific features of each component inside the cleanup vessel 100 will be specifically described below.

[0025] In this embodiment, both the first separable hull 21 and the second separable hull 22 are provided with connecting rods 210. The main hull 1 is rotatably connected to the connecting rods 210 respectively through rotating robotic arms, so as to be rotatably connected to the first separable hull 21 and the second separable hull 22 respectively. Among them, the rotating robotic arms include a first rotating robotic arm 211 and a second rotating robotic arm 221. The connecting rod 210 includes a first connecting rod disposed on the first separable hull 21 and a second connecting rod disposed on the second separable hull 22. The first rotating robotic arm 211 is rotatably connected between the first connecting rod and the main hull 1, and the second rotating robotic arm 221 is rotatably connected between the second connecting rod and the main hull 1. In an embodiment of the present application, the first rotating robotic arm 211 is disposed on a side of the first separable 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 robotic arm 221 is disposed on a side of the second separable hull 22 away from the second floating suction device and is located between the second connecting rod and the main hull 1.

[0026] The first rotating robotic arm 211 and the second rotating robotic arm 221 may be the same or different rotating robotic arms. In this embodiment, the first rotating robotic arm 211 and the second rotating robotic arm 221 are the same rotating robotic arms. Both the first rotating robotic arm 211 and the second rotating robotic arm 221 include a first motor, a base 2112, and a connecting arm 2113. Among them, the first motor of the first rotating robotic arm 211 is disposed on the first separable hull 21, and the first motor of the second rotating robotic arm 221 is disposed on the second separable hull 22. The two first motors are respectively provided with transmission rods 2111. The base 2112 of the first rotating robotic arm 211 is disposed on the main hull 1, and the base 2112 of the second rotating robotic arm 221 is disposed on the main hull 1. The connecting arm 2113 of the first rotating robotic arm 211 is pivotally connected between the base 2112 of the first rotating robotic arm 211 and one end of the transmission rod 2111, and the connecting arm 2113 of the second rotating robotic arm 221 is pivotally connected between the base 2112 of the second rotating robotic arm 221 and one end of the transmission rod 2111. The other end of the transmission rod 2111 of the first rotating robotic arm 211 is rotatably connected to the connecting rod 210 of the first separable hull 21, that is, the first connecting rod, through a connection hole 2114. The other end of the transmission rod 2111 of the second rotating robotic arm 221 is rotatably connected to the connecting rod 210 of the second separable hull 22, that is, the second connecting rod, through a connection hole 2114. The control device 4 controls the two first motors respectively to drive the connecting arms 2113 of the first rotating robotic arm 211 and the second rotating robotic arm 221 to rotate around the base 2112 respectively, thereby driving the front ends of the first separable hull 21 and the second separable hull 22 to rotate.

[0027] Understandably, the control device 4 can control the rotation of the first rotating robotic arm 211 and the second rotating robotic arm 221 respectively to drive the rotation of the first split hull 21 and the second split hull 22 respectively. The control device 4 can independently adjust the rotation angles of the first split hull 21 and the second split hull 22 by controlling each first motor respectively, so as to adjust the size of the oil containment area. Therefore, the rotation directions and rotation angles of the first split hull 21 and the second split hull 22 can be the same or different. During the process of forming the oil containment area, the corresponding split hulls can be driven to rotate by the respective rotating robotic arms either when the cleaning ship 100 is sailing, or when the cleaning ship 100 sails to a designated position within a preset range from the target area and stops sailing. In an embodiment of the present application, the oil containment area is the area formed when the rotation angles of the first split hull 21 and the second split hull 22 reach their maximum rotation angles respectively.

[0028] In this embodiment, the oil collecting baffle 20 includes a first oil collecting baffle and a second oil collecting baffle. Among them, the first oil collecting baffle is arranged between the front ends of the first floating suction device and the first split hull 21. The second oil collecting baffle is arranged between the front ends of the second floating suction device and the second split 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.

[0029] 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. Both the first oil collecting baffle and the second oil collecting baffle 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 extending 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 extending 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 communicatively connected to the two second motors 2031. The control device 4 controls the first oil collecting baffle to extend towards the second split 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 towards the first split 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 jointly surround the oil containment area with the split hull, thereby restricting the oil pollution within the oil containment area.

[0030] Further, both the first oil collecting baffle and the second oil collecting baffle include an oil containment boom 201 and a telescopic member 202. Among them, the telescopic member 202 of the first oil collecting baffle is telescopically installed on the oil containment boom 201 of the first oil collecting baffle to extend below the oil containment boom 201 of the first oil collecting baffle or retract into the oil containment boom 201 of the first oil collecting baffle. The telescopic member 202 of the second oil collecting baffle is telescopically installed on the oil containment boom 201 of the second oil collecting baffle to extend below the oil containment boom 201 of the second oil collecting baffle or retract into the oil containment boom 201 of the second oil collecting baffle. After the first oil collecting baffle and the second oil collecting baffle respectively extend out of the first split hull 21 and the second split hull 22, the control device 4 respectively controls the two second motors 2031 to drive the third driving rod 2034 of the first oil collecting baffle to drive the telescopic member 202 to extend out of the oil containment boom 201 and extend below the sea surface, and drive the third driving rod 2034 of the second oil collecting baffle to drive the telescopic member 202 to extend out of the oil containment boom 201 and extend below the sea surface, thereby stabilizing the oil containment boom 201 floating on the sea surface.

[0031] The first floating oil suction device and the second floating oil suction device can be the same or different floating oil suction devices. In this embodiment, the first floating oil suction device and the second floating oil suction device are the same floating oil suction devices. Both the first floating oil suction device and the second floating oil suction device include a number of floating oil suction boxes 32. Each floating oil suction box 32 of the first floating oil suction device is provided with a box wall extending out of the box wall of the floating oil suction box 32, and each floating oil suction box 32 of the second floating oil suction device is provided with a box wall extending out of the box wall of the floating oil suction box 32. When the control device 4 controls the first oil collecting baffle and the second oil collecting baffle to move towards the main hull 1, the box wall of the floating oil suction box 32 in the first floating oil suction device restricts the first oil collecting baffle to move only between the first floating oil suction device and the front end of the first separable hull 21, and the box wall of the floating oil suction box 32 in the second floating oil suction device restricts the second oil collecting baffle to move only between the second floating oil suction device and the front end of the second separable hull 22, so that the squeezed oil stains can be concentrated in the oil containment area relative to the floating oil suction device 3, avoiding the oil stains in the oil containment area from being excessively squeezed by the oil collecting baffle 20 and escaping from the oil containment area, thereby improving the efficiency of oil stain cleaning.

[0032] Further, both the first floating oil suction device and the second floating oil suction device include a suction pump 31 and a number of floating oil suction components 33. Among them, the number of floating oil suction components 33 of the first floating oil suction device is accommodated in the number of floating oil suction boxes 32 of the first floating oil suction device, and the number of floating oil suction components 33 of the second floating oil suction device is accommodated in the number of floating oil suction boxes 32 of the second floating oil suction device. Each box wall is provided with a number of floating balls 30 for providing buoyancy. The number of floating balls 30 drives the floating oil suction box 32 to float on the sea surface, so that the number of floating oil suction components 33 of the first floating oil suction device and the second floating oil suction device are at a height approximately flush with the oil stains. The suction pump 31 is respectively connected to each floating oil suction component 33. The control device 4 controls the suction pump 31 to drive each floating oil suction component 33 to suck the oil stains in the oil containment area. Specifically, the suction pump 31 evacuates the number of floating oil suction components 33, so that a pressure difference is generated between the side of the floating oil suction component 33 close to the suction pump 31 and the side close to the oil containment area. Since the oil stains float on the sea water and the oil collecting baffle 20 moves towards the main hull 1 to increase the thickness of the oil stains, therefore, the number of floating oil suction components 33 only needs a small pressure difference to fully adsorb the oil stains.

[0033] Even further, each floating oil suction component 33 includes a vacuum suction pipe 331, a vacuum outer cover 332, a flange 333 and a floating ring 334. Among them, the vacuum suction pipe 331 is communicated with the suction pump 31. The flange 333 is connected between the vacuum suction pipe 331 and the vacuum outer cover 332 for improving the airtightness between the vacuum suction pipe 331 and the vacuum outer cover 332. The floating ring 334 surrounds the side of the vacuum outer cover 332 away from the vacuum suction pipe 331.

[0034] In this embodiment, the cleaning ship 100 further 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 floating pipes 34 to convey the oil pollution sucked through the floating pipes 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 conveying pipe 64. Among them, the oil quantity sensor 62 can distinguish oil pollution and other substances, such as seawater, sucked into the oil storage tank 61 by the floating suction device 3 by identifying whether the sensed substance is oil pollution. The oil quantity sensor 62 is used to sense the height of the oil liquid in the oil storage tank 61. The control device 4 can control the process of the cleaning ship 100 cleaning the offshore oil pollution by controlling the opening or closing of the discharge pipe 63 and the conveying pipe 64. Specifically, each discharge pipe 63 is provided with a first valve 630. When the oil liquid height reaches a 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 conveying pipe 64 is connected between the oil storage tank 61 and the floating pipe 34. The conveying pipe 64 is provided with a second valve 640. When the oil liquid height 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.

[0035] 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 relatively separate through the control device 4 to increase the area for the cleaning ship 100 to clean the offshore oil pollution, and controls the oil collecting baffle 20 to move relative to the oil containment area to increase the thickness of the oil pollution in the oil containment area, facilitating the cleaning of the oil pollution by the floating suction device 3.

[0036] Please refer to Figure 9 and Figure 10 , this application also provides a method for cleaning offshore oil pollution. The cleaning method is applied to the offshore oil pollution cleaning ship 100. The offshore oil pollution cleaning ship 100 has been elaborated in detail above and will not be repeated here. The cleaning method includes steps S101 - S103.

[0037] Step S101, when within a preset range from the target area, respectively control the first split hull and the second split hull to relatively separate to form an oil containment area, and control the oil collecting baffle to extend to jointly enclose the oil containment area with the split hulls.

[0038] In step S101, when the cleaning ship 100 sails to a preset range from the target area, the user controls the rotating mechanical arms of the respective split and combined hulls through the control device 4 provided on the main hull 1 to drive the corresponding split and combined hulls to rotate around the main hull 1, so that the first split and combined hull 21 and the second split and combined hull 22 are relatively separated to form an oil containment area. In an 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 angles respectively, the corresponding rotating mechanical arms are 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 containment area, the user drives the first oil collecting baffle and the second oil collecting baffle to move relatively through the second motors 2031 of the first split and combined hull 21 and the second split and combined hull 22 respectively, so as to jointly enclose the oil containment area with the split and combined hulls.

[0039] Step S102, when it is recognized that the oil pollution area in the oil containment area reaches a preset area, control the oil collecting baffle to move towards the main hull from the side close to the front end of the main hull.

[0040] In step S102, the image recognition device 5 is pre-trained with an image recognition model. The image recognition model is used to recognize 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 containment area, and further determine whether the oil pollution formed after the offshore oil pollution is surrounded by the oil collecting baffle 20 is concentrated enough. To ensure that the infrared camera 51 and the color camera 52 can capture any oil containment area, the field of view areas of the infrared camera 51 and the color camera 52 at least cover the oil containment area formed when the first split and combined hull 21 and the second split and combined hull 22 both rotate to the maximum rotation angles. The image recognition model can be trained by feeding the corresponding images or historical images of the infrared camera 51 and the color camera 52 into the initial training model respectively. The initial training model can be an existing neural network model.

[0041] To improve the subsequent suction of oil pollution, the size of the oil containment area can be adjusted through the first oil collecting baffle and the second oil collecting baffle to further increase the thickness of the oil pollution in the oil containment 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 towards the main hull 1 by controlling the second motor 2031 to adjust the thickness of the oil pollution in the oil containment area. When the distance between each oil collecting baffle 20 and the wall of the floating suction box 32 in the floating suction device 3 provided on its corresponding split and combined hull reaches the preset distance, the user can control each oil collecting baffle 20 to stop moving.

[0042] Step S103, control the floating suction device to suck the oil pollution in the oil containment area.

[0043] In step S103, after the user controls the oil collecting baffle 20 to stop moving towards the main hull 1, the user can control the suction pump 31 to be in an operating state, so as to adsorb the oil pollution into the oil storage tank 61 of the oil pollution treatment device 6 through a plurality of floating suction components 33 connected to the suction pump 31, thereby completing the preliminary treatment of the offshore oil pollution. At this time, the oil pollution in the oil storage tank 61 is still mixed with seawater sucked in together with the oil pollution. The oil pollution and 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 adsorb the oil pollution-seawater mixture into the oil storage tank 61. When the oil level in the oil storage tank 61 reaches the first preset height due to the large amount of oil and seawater inside, the first valve 630 of a plurality of discharge pipes 63 is controlled to open, so that the discharge pipes 63 will release the bottom seawater. At this time, the first valve 630 of the discharge pipe 63 can be controlled to close by detecting the oil level in real time when the discharge pipe 63 discharges seawater through the oil level sensor 62, so as to end the discharge of seawater in the oil storage tank 61. When the oil pollution-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 offshore oil pollution.

[0044] In this embodiment, the oil collecting baffle 20 includes a first oil collecting baffle and a second oil collecting baffle. Both the first oil collecting baffle and the second oil collecting baffle include an oil containment boom 201 and a telescopic member 202. The telescopic member 202 is telescopically installed on the oil containment boom 201 to extend below the oil containment boom 201 or retract into the oil containment boom 201. Before controlling the oil collecting baffle to move from the side close to the front end of the main hull towards the main hull, the cleaning method further includes steps S201-S202.

[0045] Step S201, control the first oil collecting baffle to extend towards the second split hull, and control the second oil collecting baffle to extend towards the first split hull.

[0046] Step S202, control the telescopic member to extend out of the oil containment boom and extend below the sea surface.

[0047] In some feasible embodiments, when the cleaning ship 100 sails in any navigation direction, the field of view areas of the infrared camera 51 and the color camera 52 can cover the periphery of the cleaning ship 100. Before controlling the rotating robotic arms of each separable and combinable hull to drive the corresponding separable and combinable hull to rotate, the method for cleaning marine oil spills further includes the following steps: controlling the image recognition device 5 to identify the periphery of the cleaning ship 100 to determine whether there is a marine oil spill; when it is determined through the image recognition device 5 that there is a marine oil spill, the images obtained by the infrared camera 51 and the color camera 52 are used to output the oil spill direction relative to the current navigation direction of the cleaning ship 100, so as to control the cleaning ship 100 to sail in the oil spill direction.

[0048] In the above embodiments, the first separable and combinable hull and the second separable and combinable hull that can be relatively separated or relatively combined are used to increase the size of the area where the cleaning ship encloses the marine oil spill, and by controlling the oil collecting baffle to move towards the main hull, the thickness of the oil in the oil spill area is increased, so as to combine with the vacuum floating suction technology to adsorb the thickened oil and separate the adsorbed oil from the seawater therein, thereby improving the cleaning efficiency of the marine oil spill.

[0049] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, provided that these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to include these changes and modifications.

[0050] It should be understood that although the steps in the flowchart of the accompanying drawings are shown sequentially in the direction of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps is not strictly limited in order, and they can be executed in other orders. Moreover, at least some of the steps in the flowchart of the accompanying drawings may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be executed alternately or alternately with at least a part of other steps or sub-steps or stages of other steps.

[0051] The above are only the preferred embodiments of this application, and of course, the scope of the rights of this application cannot be limited thereby. Therefore, equivalent changes made according to the claims of this application still fall within the scope covered by this application.
