Description

Technical Field

[0001] The present invention relates to the technical field of floating oil collection equipment, and more specifically, to a floating oil collection ship on the water surface. Background Art

[0002] Crude oil is an important fossil fuel, mainly formed by the long-term geological action of organic matter in underground sedimentary rocks. Its composition is complex, containing various hydrocarbons (such as alkanes, cycloalkanes, and aromatic hydrocarbons) and a small amount of impurities such as sulfur, nitrogen, and oxygen. As the main source of global energy supply, crude oil can be refined to produce various petroleum products such as gasoline, diesel, and aviation fuel, which are widely used in transportation, chemical production, and electricity and other fields. However, there are certain environmental risks in the process of crude oil extraction, transportation, and storage. In particular, offshore oil fields and oil tanker transportation may cause leakage due to equipment failures, operational errors, or natural disasters, posing a serious threat to the marine ecosystem.

[0003] Crude oil leakage refers to the phenomenon that crude oil is accidentally released into the environment during the extraction, transportation, or storage process. It is particularly harmful in the marine environment, which may cause water pollution, biological death, and long-term ecological damage. Common leakage causes include oil tanker accidents, pipeline ruptures, offshore drilling platform failures, etc. To reduce the environmental impact caused by leakage, a variety of crude oil collection technologies have been developed and applied, such as oil booms (used to limit the spread of leaked crude oil), skimmers (recovering floating oil through physical means), adsorption materials, and biodegradants. In recent years, with the progress of materials science and environmental protection technologies, the development of new and efficient oil-absorbing materials and intelligent monitoring systems has further improved the ability to respond to crude oil leakage. However, how to achieve rapid response and efficient recovery of large-scale leakage remains the research focus.

[0004] In related technologies, although the microbial decomposition of crude oil is environmentally friendly and has a low consumption cost, it is easily affected by environmental factors such as temperature and pH value and the composition of crude oil, and the decomposition efficiency is very limited. And physical methods such as material adsorption are also difficult to quickly collect high-viscosity crude oil (the viscosity is usually greater than 5000 mPa·s). Therefore, how to provide an oil collection device that can quickly and efficiently collect high-viscosity floating oil has become an urgent technical problem to be solved. Summary of the Invention

[0005] In view of this, the present invention provides a floating oil collection ship on the water surface, which can continuously collect and extract high-viscosity floating oil, has a simple structure and high operation efficiency.

[0006] To achieve the above object, the present invention provides an oil skimmer for water surface, including a hull, and further including: an oil lifting assembly, including; two support members, arranged on the hull and facing each other along a first direction; two chains, respectively installed on the two support members and configured to operate under the support and guidance of the support members; a plurality of oil lifting members, both ends of the oil lifting members are respectively installed on the two chains and configured to travel back and forth between above the hull and the water surface along the transmission direction of the chains; two drive assemblies, respectively used to drive the two chains to make the two chains operate synchronously; a vibration assembly, installed on the hull and configured to apply vibration to the oil lifting members adhering with floating oil to prompt the floating oil to fall off; an oil storage assembly, including an oil storage tank, suitable for receiving the fallen floating oil.

[0007] According to an embodiment of the present invention, each of the above drive assemblies includes: a driving gear, arranged at the end of the chain far from the water surface and meshing with the chain; a first motor, suitable for driving the driving gear to rotate.

[0008] According to an embodiment of the present invention, each of the above support members includes: a side plate, arranged on the hull and extending along a second direction perpendicular to the first direction; a first boss, protruding from the side plate along the first direction; a second boss, located at the end of the chain close to the water surface, the second boss protruding from the side plate along the first direction and the cross-section being configured as an arc shape to cooperate with the first boss and the driving gear to keep the chain at a preset tension.

[0009] According to an embodiment of the present invention, the above first boss includes a horizontal section parallel to the water surface and an inclined section forming a preset angle with the horizontal section to support and guide the chain.

[0010] According to an embodiment of the present invention, the above oil storage assembly further includes an oil guide plate, suitable for guiding the fallen floating oil to the oil storage tank.

[0011] According to an embodiment of the present invention, the above oil guide plate is arranged at the horizontal section and penetrates through the two chains along the first direction, and the oil lifting member receives the vibration of the vibration assembly during the process of passing above the oil guide plate, so that the floating oil drips onto the oil guide plate.

[0012] According to an embodiment of the present invention, there are two above oil storage tanks, and they are respectively located on both sides of the oil lifting assembly in the first direction.

[0013] According to an embodiment of the present invention, the above oil guide plate is configured as an arc-shaped plate gradually bulging from the two oil storage tanks to the oil lifting assembly to guide the dripping floating oil into the oil storage tank.

[0014] According to an embodiment of the present invention, the vibration assembly includes: a resonance unit, installed on the hull and configured to generate vibration in an energized state; a vibration conduction plate, connected to the resonance unit and configured to sequentially transfer the vibration generated by the resonance unit to at least one oil-lifting member passing above the oil guide plate, so that the floating oil adhering to the at least one oil-lifting member drips onto the oil guide plate.

[0015] According to an embodiment of the present invention, the oil-lifting member includes: a first rod member, extending along a first direction and rotatably installed between two chains; a plurality of second rod members, arranged in a radial direction on the first rod member, the fixed ends of the second rod members are connected to the first rod member, and during the movement along the transmission direction of the chains, based on the action of gravity, the free ends of the second rod members are always located directly below the fixed ends.

[0016] For the floating oil collection ship provided by the present invention, under the support of a support member, two chains are respectively driven by two drive assemblies to rotate synchronously. The oil-lifting members move back and forth between above the hull and the water surface along with the operation of the chains, so as to continuously adhere to the floating oil on the water surface and use the principle of shear thinning to separate the floating oil from the oil-lifting members, thereby collecting the extracted floating oil. In this way, a relatively high oil-lifting efficiency can be maintained for a long time, which is more environmentally friendly. Description of the Drawings

[0059] An exemplary embodiment of the present invention provides an oil slick collecting ship on the water surface, such as Figures 1 to 5As shown, it includes a hull 6, and also includes an oil lifting assembly 1, two drive assemblies 2, a vibration assembly 3 and an oil storage assembly 4. The oil lifting assembly 1 includes two support members 11, two chains 12 and a plurality of oil lifting members 13. The two support members 11 are arranged on the hull 6 and face each other along a first direction. The two chains 12 are respectively installed on the two support members 11 and are configured to operate under the support and guidance of the support members 11. The two ends of the oil lifting member 13 are respectively installed on the two chains 12 and are configured to travel back and forth between above the hull 6 and the water surface along the transmission direction of the chain 12. The two drive assemblies 2 are respectively used to drive the two chains 12 to make the two chains 12 operate synchronously. The vibration assembly 3 is installed on the hull 6 and is configured to apply vibration to the oil lifting member 13 adhering to the floating oil to prompt the floating oil to fall off. The oil storage assembly 4 includes an oil storage tank 41 suitable for receiving the fallen floating oil.

[0060] In such an embodiment, the support member 11 is used to support the chain 12, that is, it cooperates with the drive assembly 2 to make the chain 12 have a certain tension. The oil lifting member 13 is arranged between the two chains 12 along the first direction, and the plurality of oil lifting members 13 are spaced apart along the transmission direction (or extension direction) of the chain 12. It should be noted that the two chains 12 rotate synchronously, that is, the two drive assemblies 2 start and stop synchronously and maintain the same rotational speed, so that the oil lifting member 13 can be stably driven by the chains 12 on both sides (that is, the oil lifting member 13 always remains parallel to the first direction), successively immerse into the water from above the hull 6 to adhere to the floating oil, then return above the hull 6 from the water surface, and after the vibration assembly 3 applies vibration excitation, the floating oil adhering to the oil lifting member 13 gradually falls off and is collected by the oil storage tank 41. In this way, the viscosity difference between the floating oil and water (seawater) can be utilized to continuously extract the floating oil, and the periodic shear force generated during the vibration process is used to thin the floating oil adhering to the surface of the oil lifting member, and then it freely falls off, effectively improving the collection efficiency of the floating oil on the water surface, being widely applicable to the collection of floating oils with different viscosities, reducing the operation cost, and being more in line with environmental protection requirements.

[0061] In an exemplary embodiment, as Figure 4 shown, each drive assembly 2 includes a driving gear 21 and a first motor 22. The driving gear 21 is arranged at the end of the chain 12 away from the water surface and meshes with the chain 12. The first motor 22 is suitable for driving the driving gear 21 to rotate.

[0062] In such an embodiment, the driving gear 21 is arranged away from the water surface, and correspondingly, the first motor 22 drives the driving gear 21 away from the water surface as well, so as to avoid the water body fluctuation that may affect the normal operation. The driving gear 21 is located at one end of the chain 12, and the support member 11 mainly provides support for the chain 12 from the other end of the chain 12, so that the chain 12 has an appropriate tension force (the specific value is comprehensively selected according to the specifications of the chain 12 and the parameters of the first motor 22). The driving gears 21 of the two driving assemblies 2 are coaxially arranged to ensure the synchronous rotation of the two chains 12.

[0063] According to an embodiment of the present disclosure, as Figure 2 and Figure 3 shown, each support member 11 includes a side plate 111, a first boss 112, and a second boss 113. The side plate 111 is disposed on the hull 6 and extends in a second direction perpendicular to the first direction. The first boss 112 projects from the side plate 111 in the first direction, and the second boss 113 is located at the end of the chain 12 close to the water surface. The second boss 113 projects from the side plate 111 in the first direction and its cross section is configured as an arc, so as to cooperate with the first boss 112 and the driving gear 21 to keep the chain 12 under a preset tension force.

[0064] In such an embodiment, the side plate 111 is mounted on the hull 6 for installing the first boss 112 and the second boss 113. The first boss 112 and the second boss 113 are used to support and cooperate with the driving gear 21 to tension the chain. Specifically, the first boss 112 is mainly used to support the straight section in the middle of the chain 12 to prevent this part from sagging under the influence of gravity. The first boss 112 is divided into an upper boss and a lower boss. The upper boss is disposed inside the chain 12 to support the upper straight section of the chain 12, and the lower boss is disposed outside the chain 12 to support the lower straight section of the chain 12. The second boss 113 is used to support the transition section (i.e., the arc-shaped part) of the chain 12. The second boss 113 is preferably disposed inside the chain 12 to provide good support for the transition section and maintain the tension force.

[0065] The second boss 113 can also be disposed outside the chain 12. When disposed outside, the length of the upper boss needs to be appropriately extended so that the upper boss and the second boss 113 have at least partial overlap. This setting method is applicable to the usage situation with a relatively small preset tension force.

[0066] Further according to an embodiment of the present disclosure, as Figure 3 shown, the first boss 112 includes a horizontal section 1121 parallel to the water surface and an inclined section 1122 forming a preset angle with the horizontal section 1121 to support and guide the chain 12.

[0067] In such an embodiment, the chain 12 is configured in a zigzag shape, with a part parallel to the water surface and supported by the horizontal section 1121 to facilitate receiving the vibration excitation from the vibration assembly 3; another part is inclined relative to the water surface and supported by the inclined section 1122 to send the oil lifting member 13 from above the hull 6 into the water.

[0068] Exemplarily, the included angle between the inclined part of the chain 12 and the water surface is preferably 45°.

[0069] In some other embodiments, the drive assembly 2 further includes a secondary gear 23 disposed on the inclined part of the chain 12 and meshing with the chain 12. The secondary gear 23 rotates synchronously with the driving gear 21 to maintain the stability of the operation of the chain 12, disperse wear, and extend the service life of the system.

[0070] In an exemplary embodiment, as Figure 5 shown, the oil storage assembly 4 further includes an oil guide plate 42 adapted to guide the shed floating oil to the oil storage tank 41.

[0071] In such an embodiment, the shed floating oil first drips onto the oil guide plate 42 and then flows along the oil guide plate 42 into the oil storage tank 41 to prevent the floating oil from deviating from the oil storage tank 41 under the influence of the environment (such as wind conditions) during the falling process.

[0072] In some other embodiments, the oil guide plate 42 is coated with an oil-repellent coating and is inclined at a small angle (5° - 30°) with respect to the horizontal plane to facilitate the flow of the floating oil.

[0073] According to an embodiment of the present disclosure, as Figure 5 shown, the oil guide plate 42 is disposed at the horizontal section 1121 and penetrates through the two chains 12 in the first direction. The oil lifting member 13 receives the vibration from the vibration assembly 3 during the process of passing above the oil guide plate 42, so that the floating oil drips onto the oil guide plate 42.

[0074] In such an embodiment, the oil guide plate 42 is located between the two chains 12 and penetrates through the two chains 12. When the oil lifting member 13 passes above the oil guide plate 42, the vibration assembly 3 shakes the floating oil onto the oil guide plate 42 and flows into the oil storage tank 41, thereby preventing the floating oil from falling onto other oil lifting members 13 and affecting the oil collection efficiency.

[0075] Specifically, the driving gear 21 preferably rotates clockwise to drive the chain 12. The multiple oil lifting members 13 sequentially pass above the oil guide plate 42 to receive the vibration excitation, and return to the water surface under the oil guide plate 42 to continue lifting oil. The oil guide plate 42 effectively prevents the oil lifting member 13 from bringing the already shed floating oil back into the water.

[0076] Correspondingly, the driving gear 21 can also rotate counterclockwise to drive the chain 12, that is, after the oil lifting member 13 adheres to the floating oil, it first passes under the oil guiding plate 42 and then moves above the oil guiding plate 42 to receive vibration excitation. Without the oil guiding plate 42, the dripping floating oil will drip onto the oil lifting member 13 that has not yet received vibration excitation, resulting in incomplete oil storage when the oil lifting member 13 moves to the excitation area and carrying part of the floating oil back to the water surface. Therefore, the oil guiding plate 42 can still play a role in improving the oil collection efficiency.

[0077] In an exemplary embodiment, as Figure 5 shown, there are two oil storage tanks 41, which are respectively located on both sides of the oil lifting assembly 1 in the first direction.

[0078] In such an implementation manner, since the chain 12 and the side plate 111 are arranged along the second direction, arranging the two oil storage tanks 41 on both sides of the oil lifting assembly 1 in the first direction can reasonably utilize the space on the hull 6 and can arrange larger-sized oil storage tanks 41.

[0079] According to an embodiment of the present disclosure, as Figure 5 shown, the oil guiding plate 42 is configured as an arc-shaped plate that gradually bulges from the two oil storage tanks 41 to the oil lifting assembly 1 to guide the dripping floating oil into the oil storage tank 41.

[0080] In such an implementation manner, by setting the oil guiding plate 42 as an arc-shaped plate, similar to an arch shape, it can prompt the floating oil to flow into the oil storage tank 41 as soon as possible and avoid long-term accumulation and difficult cleaning at the oil guiding plate 42.

[0081] In some other embodiments, a first grid plate 411 is provided at the opening of the oil storage tank 41 to prevent sundries from entering the oil storage tank 41.

[0082] More specifically, a transfer oil tank 43 is further provided between the two oil storage tanks 41. The transfer oil tank 43 is located below the oil lifting assembly 1 and is simultaneously connected to the two oil storage tanks 41, which can increase the oil storage capacity. The transfer oil tank 43 is separated from the two oil storage tanks 41 by a second grid plate 431 to further block sundries from entering, and the allowable passing size of the first grid plate 411 is larger than the allowable passing size of the second grid plate 431. When there is more collected floating oil or when transfer is required, an oil pump is used to extract from the transfer oil tank 43.

[0083] In an exemplary embodiment, as Figure 4As shown, the vibration assembly 3 includes a resonance unit 31 and a vibration conduction plate 32. The resonance unit 31 is installed on the hull 6 and is configured to generate vibrations in the energized state. The vibration conduction plate 32 is connected to the resonance unit 31 and is configured to sequentially transfer the vibrations generated by the resonance unit 31 to at least one oil lifting member 13 passing over the oil guiding plate 42, so that the floating oil adhering to at least one oil lifting member 13 drips onto the oil guiding plate 42.

[0084] In such an embodiment, the resonance unit 31 is mounted on the hull 6, with a height approximately flush with the horizontal portion of the chain 12, and transfers vibrations to the oil lifting member 21 through the vibration conduction plate 32.

[0085] More specifically, the coverage area of the vibration conduction plate 32 can be determined according to the size of the oil guiding plate 42. For example, if the oil guiding plate 42 can receive the floating oil dripping from at most 4 oil lifting members 13 at the same time, then the vibration conduction plate 32 is preferably configured to cover 2 - 3 oil lifting members 13 at the same time. While ensuring the oil collection efficiency, it minimizes the impact on the oil lifting members 13 that cannot be covered by the oil guiding plate 42, avoiding the floating oil from directly dripping onto the hull 6 or falling back into the water.

[0086] The resonance unit 31 is composed of an energy converter, a signal amplifier, and a signal generator. The signal generator generates and emits a signal, the signal amplifier receives the signal and transfers it to the energy converter, and the energy converter converts the electrical signal into mechanical vibrations.

[0087] Exemplarily, the resonance unit 31 includes but is not limited to using a resonance horn, and the vibration frequency is preferably 25w, which can be adjusted according to the actual situation. For example, heavy oil (usually with a viscosity greater than 100 mPa·s) is preferably at a low frequency and large amplitude, and light oil (usually with a viscosity less than 10 mPa·s) is preferably at a high frequency and small amplitude.

[0088] In an exemplary embodiment, as Figure 5 shown, the oil lifting member 13 includes a first rod 131 and a plurality of second rods 132. The first rod 131 extends in the first direction and is rotatably installed between two chains 12. A plurality of second rods 132 are arranged in the radial direction on the first rod 131. The fixed ends of the second rods 132 are connected to the first rod 131, and during the movement along the transmission direction of the chain 12, due to the action of gravity, the free ends of the second rods 132 are always located directly below the fixed ends.

[0089] In such an embodiment, both ends of the first rod 131 are rotatably connected to the two chains 12 respectively. While the two chains 12 drive the oil-lifting member 13 to move, the oil-lifting member 13 can rotate relative to the chains 12. The rotation of the oil-lifting member 13 is achieved by gravity. During the movement along with the chains 12, the second rod 132 is always in a natural hanging state. At the same time, by arranging multiple second rods 132 at intervals, the contact area between the oil-lifting member 13 and the floating oil is increased, and the resistance during movement in water is reduced.

[0090] Exemplarily, the second rod 132 is configured as a cylindrical shape to further increase the contact area with the floating oil and reduce the water flow resistance.

[0091] According to the implementation of the present disclosure, both ends of the first rod 131 are connected to the chain 12 through bearings, and in the first direction, the length of the first rod 131 is greater than the distance between the two chains 12, that is, the ends of the first rod 131 extend out of the chain 12 to contact the vibration conduction plate 32 when passing above the oil guide plate 42.

[0092] Exemplarily, the second rod 132 is preferably made of stainless steel material, which has good corrosion resistance, easy surface cleaning, long service life, and high strength and stiffness of stainless steel, and is not easily deformed or damaged.

[0093] In some other embodiments, the lengths of two adjacent second rods 132 are different, and the free ends of the second rods 132 are arranged in a substantially sinusoidal or cosine curve. In this way, irregular vortices can be generated in the water body during movement, breaking the continuity of the oil layer, and at the same time, the oil layers at multiple depths can be adhered to, reducing the possibility of missed capture.

[0094] Figure 6 It is a three-dimensional structure diagram of a water surface floating oil collection ship provided by another exemplary embodiment of the present invention.

[0095] In an exemplary embodiment, as Figure 6 shown, the water surface floating oil collection ship further includes an auxiliary oil collection assembly 5, which is installed at the head of the hull 6 and is suitable for pushing the water surface floating oil to make the floating oil approach the oil-lifting assembly 1.

[0096] According to the embodiment of the present disclosure, the auxiliary oil collection assembly 5 includes two pusher members arranged facing each other. Each pusher member includes a plate body 51, a first connecting rod 52, a second connecting rod 53, and a second motor 54. The plate body 51 is rotatably installed on the hull 6, is arranged perpendicular to the water surface and at least partially immersed in the water. One end of the first connecting rod 52 is rotatably connected to the plate body 51, and the other end is rotatably connected to the second connecting rod 53. The second motor 54 is suitable for driving the second connecting rod 53 to rotate, so as to drive the plate body 51 to push the floating oil near the head of the hull 6 towards the oil-lifting assembly 1 through the first connecting rod 52.

[0097] In such an embodiment, the first connecting rod 52 and the second connecting rod 53 form a crank connecting rod mechanism. Under the double restrictions of the rotational pair connection between the plate body 51 and the first connecting rod 52 and the rotational pair connection between the plate body 51 and the hull 6, the crank connecting rod mechanism can drive the plate body 51 to rotate within a certain angular range (which can be set according to actual conditions), achieving the effect of converging floating oil.

[0098] Optionally, the hull 6 is controlled to move forward by a turboprop and a driving motor.
