DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-Figure 5 The present invention provides an offshore oil leakage collection device, comprising a collection ship 1, oil collecting components for collecting offshore oil are respectively arranged on both sides of the bow of the collection ship 1, an oil suction component for collecting offshore oil is arranged at the bow of the collection ship 1, the oil suction component is connected with an oil-water separator 12, the oil outlet end of the oil-water separator 12 is connected with a first oil storage tank 13, the oil suction component, the oil-water separator 12, and the first oil storage tank 13 are fixedly installed on the collection ship 1; transportation components for transporting the collected oil are respectively arranged on both sides of the hull of the collection ship 1, the transportation component is connected with the first oil storage tank 13 through an oil pipeline 14, and the oil pipeline 14 and the transportation component are detachably connected.

[0026] The present invention can gather the oil on the sea by arranging the oil collecting components on both sides of the bow of the collecting ship 1, so that the oil is between the bow of the collecting ship 1 and the oil collecting components, collect the oil on the sea by the oil suction components, and transport the oil to the oil-water separator 12, the oil-water separator 12 separates the seawater from the oil, and transports the oil to the first oil storage tank 13; and by transporting the oil in the first oil storage tank 13 to the transportation component, the collecting ship 1 can continue to collect the oil, which effectively improves the collection efficiency.

[0027] A further optimized solution is provided, in which the oil collecting assembly includes an intercepting plate 2, one end of which is fixedly connected to the hull of the collecting ship 1, a through groove 21 is provided at the end of the intercepting plate 2 facing the collecting ship 1, a movable plate 23 is slidably connected in the through groove 21, the movable plate 23 extends out of the through groove 21 and is slidably connected to the end of the collecting ship 1 with a slide groove 11, and the slide groove 11 is provided on the hull of the collecting ship 1.

[0028] When the oil collecting assembly does not need to collect oil, the bottom surface of the movable plate 23 is above the sea surface, which effectively reduces the sailing resistance of the collecting ship 1 and enables the collecting ship 1 to quickly reach the area where oil collection is required.

[0029] When reaching the edge of the oil collection area, the movable plate 23 is extended out of the through slot 21 into the sea water, so that the movable plate 23 can effectively intercept the oil. Then, the oil on the sea is gathered between the bow of the collection ship 1 and the movable plate 23 by the movement of the collection ship 1.

[0030] In a further optimized solution, the through slot 21 is connected to the slide slot 11 , so that the end of the movable plate 23 extending into the slide slot 11 can effectively move along the slide slot 11 .

[0031] In a further optimized solution, the movable plate 23 extends into the through slot 21 and is fixedly connected to the top surface with a plurality of telescopic rods 22, and one end of the telescopic rod 22 away from the movable plate 23 is fixedly connected to the top of the through slot 21. The telescopic rod 22 can control the length of the movable plate 23 extending out of the through slot 21.

[0032] The telescopic rod 22 can be an electric telescopic rod or a hydraulic cylinder.

[0033] The electric telescopic rod is generally composed of an inner tube and an outer tube. The inner tube is fixed and the outer tube can be extended and retracted relative to the inner tube. Under the action of the transmission mechanism, the outer tube can be freely extended or shortened within a certain range. The control system is the key to the precise control of the electric telescopic rod, which is mainly controlled by a computer or microprocessor. Users can set the working parameters of the telescopic rod according to specific needs, such as telescopic speed, telescopic distance, and telescopic direction. The control system can also receive and process signals from limit sensors. When the telescopic rod reaches the preset position, the control system will stop the operation of the motor to avoid excessive extension.

[0034] The working principle of the hydraulic cylinder is mainly based on Pascal's law, that is, the pressure of the enclosed liquid can be evenly transmitted in the liquid, thereby achieving force amplification and change of direction. The hydraulic cylinder is usually composed of a cylinder barrel, a piston, a piston rod, a seal, an oil inlet and an outlet, etc. The cylinder barrel is the main body of the hydraulic cylinder, with a piston installed inside. The piston is connected to the piston rod. The seal is used to prevent oil leakage, and the oil inlet and outlet are used to connect the oil pipe of the hydraulic system so that the oil can enter and exit the hydraulic cylinder. When the hydraulic oil enters the cylinder barrel from the oil inlet of the hydraulic cylinder, the hydraulic oil will push the piston to move away from the oil inlet. Since the piston is connected to the piston rod, the piston rod will also move with it, thereby achieving external work. For example, in a hydraulic jack, after the hydraulic oil enters the hydraulic cylinder, the piston rises, driving the piston rod to rise, and then lifting the heavy object. When the piston of the hydraulic cylinder needs to move in the opposite direction, the hydraulic oil will flow out from the oil outlet of the hydraulic cylinder, and at the same time, new hydraulic oil will enter from the oil inlet, pushing the piston to move in the opposite direction, and the piston rod will also retract. For example, in the boom cylinder of a hydraulic excavator, when the boom needs to be lowered, the oil return process of the hydraulic cylinder will occur, causing the boom to drop.

[0035] According to a further optimized solution, one end of the movable plate 23 extending out of the through slot 21 is fixedly connected to a propeller 24 , and the propeller 24 is arranged at one end of the movable plate 23 away from the collecting vessel 1 .

[0036] The propeller 24 is an underwater propeller.

[0037] The working principle of underwater propulsion is mainly based on Newton's third law, that is, the action force and reaction force are equal in magnitude and opposite in direction. It propels itself forward in the water by generating backward thrust.

[0038] The following are the working principles of several common underwater thrusters:

[0039] Propeller propeller: The propeller propeller is driven by a motor or engine to rotate the propeller. The propeller blades push the water backwards. According to Newton's third law, the water will produce a forward reaction force on the propeller, thereby pushing the underwater propeller forward. This type of propeller is widely used in large underwater equipment such as ships and submarines, and has the advantages of high efficiency and high thrust.

[0040] Water jet propulsion: Water jet propulsion sucks water through a water pump and then sprays it backward at high speed to generate forward thrust. The advantages of this propulsion are simple structure, low noise and good maneuverability. It is often used in high-speed speedboats, submersibles and other underwater equipment that require high maneuverability.

[0041] Magnetohydrodynamic propulsion: Magnetohydrodynamic propulsion uses the interaction between magnetic field and electric current to make seawater produce backward Lorentz force, thereby pushing the underwater propeller forward. The advantages of this propeller are no mechanical parts, low noise and high efficiency. It is still in the research and testing stage and has not yet been widely used.

[0042] Bionic propeller: Bionic propeller imitates the movement of fish or other aquatic organisms and generates thrust by swinging or undulating. The advantages of this propeller are good maneuverability and concealment. It is used in some special-purpose underwater robots.

[0043] In a further optimized solution, the propeller 24 is arranged on the back side of the movable plate 23. When the movable plate 23 is extended into the seawater, in order to effectively reduce the increased moving resistance of the collection ship 1 caused by the contact between the movable plate 23 and the seawater and reduce the force on the movable plate 23, the propeller 24 applies thrust to the movable plate 23, which not only effectively reduces the moving resistance of the collection ship 1, but also effectively reduces the resistance on the movable plate 23.

[0044] Further optimization scheme, the oil suction assembly includes a support plate 3, the bottom surface of the support plate 3 is symmetrically provided with a lifting part, the support plate 3 is fixedly connected with an oil suction pump, the oil inlet end of the oil suction pump is connected with an oil suction pipe 33 through a three-way valve, and the end of the oil suction pipe 33 away from the three-way valve is in contact with the sea surface. The suction force of the oil suction pump enables the oil suction pipe 33 to absorb the oil on the sea. The oil is transported to the oil-water separator 12 by the oil suction pump.

[0045] In a further optimized solution, the oil suction pipe 33 is arranged between the interception plate 2 and the bow of the collection ship 1. As the collection ship 1 moves, the oil is gathered between the interception plate 2 and the bow of the collection ship 1, so that the oil suction pipe 33 can effectively absorb the oil in the area where the oil is gathered.

[0046] In a further optimized solution, the lifting part includes a fixed column 31 fixedly installed in the bow of the collection ship 1, and a movable column 32 is slidably connected in the top surface of the fixed column 31, and one end of the movable column 32 extending outside the fixed column 31 is fixedly connected to the support plate 3. The movable column 32 is raised and lowered in the fixed column 31, so that the oil inlet end of the oil suction pipe 33 can always abut against the sea surface.

[0047] According to a further optimized solution, the transport component includes a transport ship 4, on which a second oil storage tank 41 is installed. The top surface of the second oil storage tank 41 is fixedly connected and communicated with an oil inlet hopper 42, and the oil inlet hopper 42 is detachably connected and communicated with the oil pipeline 14.

[0048] The transport ship 4 transports the oil in the first oil storage tank 13 through the second oil storage tank 41, so that the first oil storage tank 13 will not be filled with oil, so that the collection ship 1 can continuously collect oil, effectively improving the oil collection efficiency.

[0049] In order to prevent the influence of sea waves on the oil being transported from the first oil storage tank 13 to the second oil storage tank 41, the oil delivery pipe 14 adopts a telescopic hose.

[0050] The telescopic hose is a hose with retractable properties. The telescopic hose can freely expand and contract within a certain range, which is convenient for adjusting the length and adapting to different usage scenarios. The telescopic hose has good flexibility and can be bent at different angles and directions, which is easy to install and use. The telescopic hose is usually made of corrosion-resistant materials, such as PVC, rubber, etc., and is suitable for the transportation of a variety of media. The telescopic hose has good sealing properties and can effectively prevent medium leakage, ensuring the safety and stability of the transportation process.

[0051] In order to prevent the oil in the second oil storage tank 41 from flowing out of the oil inlet 42 due to the shaking of the transport ship 4 during the transportation of oil, a sealing cover can be installed on the oil inlet 42 to seal the oil inlet 42, so that the oil in the second oil storage tank 41 is in a sealed environment, which is convenient for transportation at sea.

[0052] Working process: When an offshore oil leak occurs, the collecting ship 1 is used to rush to the sea area where the oil leaks. In order to reduce the navigation resistance of the collecting ship 1, at this time, by retracting the telescopic end of the telescopic rod 22, the movable plate 23 is placed above the sea surface, so that the collecting ship 1 can quickly rush to the leaking sea area. When the collecting ship 1 reaches the edge of the oil leak area, at this time, by extending the telescopic end of the telescopic rod 22, the end of the movable plate 23 extending outside the through groove 21 can be effectively extended into the sea water, so that the movable plate 23 can effectively intercept the oil. Then, the collecting ship 1 moves along the planned path, so that the oil on the sea can be effectively gathered between the bow of the collecting ship 1 and the movable plate 23. At this time, since the movable column 32 rises and falls along the fixed column 31, the oil inlet end of the oil suction pipe 33 can always be in contact with the sea surface, that is, the oil inlet end of the oil suction pipe 33 The oil is brought into contact with the oil on the sea, and at the same time, the oil suction pump is turned on, and the suction force of the oil suction pump is used to enable the oil suction pipe 33 to absorb the oil on the sea; the oil is transported to the oil-water separator 12 through the oil suction pump, and the drainage end of the oil-water separator 12 extends out of the collecting ship so that water can flow back into the sea, and the oil outlet end of the oil-water separator 12 can transport the oil to the first oil storage tank 13, and the oil in the first oil storage tank 13 is pumped, so that the oil in the first oil storage tank 13 is transported to the second oil storage tank 41 through the oil pipeline 14. After the second oil storage tank 41 is filled with oil, the transport ship 4 leaves the collecting ship 1 and transports the collected oil. The collected oil is transported by several transport ships 4, so that the first oil storage tank 13 will not be full of oil, so that the collecting ship 1 can continuously collect the oil on the sea along the planned route, effectively improving the oil collection efficiency.
