Description

Technical Field

[0001] This invention relates to the field of shipbuilding, and more particularly to a side-mounted oil recovery device for ships. Background Technology

[0002] Oil spills, especially large-scale ones, cause severe pollution to the aquatic environment, directly endangering human living conditions. Seabed oil extraction also contributes to oil pollution, exacerbating marine environmental pollution and posing a serious threat to the global ecosystem. The frequent occurrence of red tides in recent years serves as a stark reminder of the severity of this pollution problem.

[0003] Existing marine-mounted side-mounted oil recovery devices encounter significant water resistance when using oil booms to contain and divert oil spills at sea (current oil recovery devices typically involve vertically submerging the bottom of the boom below the sea surface, then dragging the boom forward from the ship to contain and divert the oil spill). This makes it difficult to increase navigation speed, thus significantly reducing oil recovery efficiency. Furthermore, the effectiveness of existing oil boom structures is greatly reduced, or even completely ineffective, when operating in rough seas.

[0004] Therefore, developing a marine side-mounted oil recovery device with strong adaptability to sea conditions and significantly reduced water flow resistance has important application value. Summary of the Invention

The support tube is vertically mounted on the oil collection tank. The third support base is generally C-shaped with a sliding groove. The third support base is rotatably mounted on a rotating shaft on the support tube through a rotating hole provided on the bottom surface of the groove, so that the third support base can tilt forward through the rotating hole and the rotating shaft. The first linear actuator is mounted on the oil collection tank, and the top end of the first linear actuator is hinged to the top end of the third support base through a first transmission rod. The oilcloth component is disposed inside the support tube to seal the gap between the support tube and the third support base.

[0010] Preferably, the oilcloth component includes a rotating shaft and an oilcloth. The rotating shaft is rotatably disposed inside the support tube. A torsion spring is sleeved on one end of the rotating shaft. One end of the torsion spring is connected to the rotating shaft, and the other end of the torsion spring is connected to the inner wall of the support tube. One end of the oilcloth is wound around the rotating shaft, and the other end of the oilcloth passes through a long through hole on the third side wall of the support tube and is connected to the side wall of the third support seat to cover the gap between the support tube and the third support seat.

[0011] Preferably, the oil containment boom includes an oil containment boom and a lifting component. One end of the oil containment boom is provided with a first slider, and the other end of the oil containment boom is axially slidably fitted into the groove of the third support seat through the first slider. The other end of the oil containment boom is connected to the second support component. The lifting component is provided on the oil containment boom to adjust the depth of the bottom of the oil containment boom below the sea surface.

[0012] Preferably, the lifting component includes a counterweight tube, buoyancy balls, branch pipes, a main pipe, and an air pump. One end of the counterweight tube is disposed on the bottom edge of the oil boom, and multiple counterweight tubes are distributed longitudinally and spaced apart along the oil boom. The buoyancy balls are connected through to the bottom end of the counterweight tube, and the multiple buoyancy balls correspond one-to-one with the multiple counterweight tubes. One end of the branch pipe is connected through to the top end of the counterweight tube, and the multiple branch pipes correspond one-to-one with the multiple counterweight tubes. One end of the main pipe is connected through to the other end of each of the multiple branch pipes, and the other end of the main pipe is connected through to the air pump disposed on the vessel.

[0013] Preferably, the second support member includes a second power member, a boom, and a buoy. The second power member is mounted on the deck of the vessel to drive the boom to move, and the buoy adjusts the deployment range of the oil boom on the boom.

The second linear actuator is disposed on the pontoon, and the top end of the second linear actuator is hinged to the top end of the fourth support base through a second transmission rod.

[0015] The beneficial effects of the technical solutions provided by the embodiments of the present invention include at least the following: (1) The marine side-mounted oil recovery device of the present invention has a reasonable structural design, a high degree of automation, low water flow resistance and strong adaptability to harsh sea conditions; (2) The marine side-mounted oil recovery device of the present invention is equipped with a third support and an oil boom. When the first linear actuator is shortened to a predetermined position and then stops, it will cause the top of the third support to tilt forward. The third support will cause the top of the oil boom to tilt forward through the first slider. At this time, the bottom of the oil boom and the counterweight pipe will tilt backward in the seawater. That is, by reducing the angle between the oil boom and the sea surface in front (less than 90 degrees), the water flow resistance is significantly reduced, and the ship speed and oil recovery efficiency are improved. When the first linear actuator is extended to a predetermined position and then stops, it will cause the top of the third support to tilt backward. The third support will cause the top of the oil boom to tilt backward through the first slider. At this time, the bottom of the oil boom and the counterweight pipe will tilt forward in the seawater. That is, by increasing the angle between the oil boom and the sea surface in front (greater than 90 degrees), the wind resistance is significantly reduced. In addition, because the counterweight pipe is submerged to a greater depth in the sea, the reliability of oil recovery under large waves is significantly improved. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] according to Figures 1-9As shown, a marine side-mounted oil recovery device includes an oil recovery component and an oil containment and guide component. Both the oil recovery component and the oil containment and guide component are installed on the vessel 1, and the oil containment and guide component is connected to the oil recovery component to contain the oil spill on the sea surface and guide the oil spill to the oil recovery component.

[0024] The oil recovery unit includes a first support member and an oil recovery tank 2. The first support member is mounted on the vessel 1 to provide support, and the oil recovery tank 2 is mounted on the first support member and is driven to move vertically along the side of the vessel 1, facilitating the recovery of spilled oil. The first support member includes a mounting base 3, a support frame, and a driving component. The mounting base 3 is mounted on the vessel 1, the support frame is mounted on the mounting base 3, and the driving component is mounted on the support frame to drive the oil recovery tank 2 to move vertically.

[0025] The mounting base 3 is generally rectangular in shape and is fixedly installed on the deck of the vessel 1 near the side of the vessel. It provides quick positioning and installation for the support frame. Furthermore, there are two mounting bases 3, which are spaced apart on the deck of the vessel 1 near the side of the vessel according to the design spacing.

[0026] The support frame includes a first support base 4, a slide rail 5, and a reinforcing frame 6. The first support base 4 is detachably mounted on the mounting base 3. The slide rail 5 is fixedly mounted on the first support base 4 to provide support and guidance for the oil collection tank 2. The reinforcing frame 6 is fixedly mounted on the first support base 4 to improve overall stability.

[0027] Two first support bases 4 are provided, and the two first support bases 4 are detachably installed on the mounting base 3 one after the other. One end of the slide rail 5 is vertically fixed on the first support base 4, and the other end of the slide rail 5 extends vertically towards the bottom of the ship. Two slide rails 5 are provided, and the two slide rails 5 are vertically fixed on the two first support bases 4 one after the other. The reinforcing frame 6 is generally rectangular in shape, and the reinforcing frame 6 is fixedly installed on the first support base 4 to provide support stability for the slide rail 5.

[0028] The driving component includes a transmission component and a first power component, both of which are mounted on the support frame. The first power component drives the oil collection tank 2 to move vertically via the transmission component. The transmission component includes a screw 7 and a nut 8. The screw 7 is rotatably mounted on the reinforcing frame 6, and the nut 8 is fitted onto the screw 7. Furthermore, both ends of the screw 7 are rotatably mounted on the reinforcing frame 6 via second support seats, and the axis of the screw 7 is parallel to the longitudinal line of the slide rail 5. Two nuts 8 are spaced apart and fitted onto the screw 7, and both nuts 8 are connected to the oil collection tank 2.

[0029] The first power component includes a motor 9, a first gear, and a second gear. The motor 9 is fixedly mounted on the reinforcing frame 6. The first gear is fixedly mounted on the rotating shaft of the motor 9, and the second gear is fixedly mounted on the screw 7, and the second gear meshes with the first gear. Furthermore, the motor 9 has a built-in circumferential locking function (the motor 9 is equipped with a mechanical braking device).

[0030] The oil recovery tank 2 is slidably mounted on the slide rail 5 via pulleys 10, and is fixedly connected to the side wall of the nut 8. When the motor 9 drives the screw 7 to rotate via the first gear and the second gear, the rotating screw 7 drives the oil recovery tank 2 to move vertically via the nut 8, thereby controlling the bottom of the oil recovery tank 2 to sink to a predetermined depth below the sea surface, allowing the oil recovery tank 2 to quickly enter the oil spill recovery working state. Alternatively, a pressure sensor is installed at the bottom of the vessel 1. The pressure sensor automatically transmits signals to the controller based on the detected draft of the vessel 1 at different times (e.g., when the vessel 1 is fully loaded and empty), so as to adjust the depth of the bottom of the oil recovery tank 2 below the sea surface in a timely manner, thereby improving the oil recovery efficiency.

[0031] The oil containment and guide device includes an oil containment device and a second support device. The oil containment device is connected to the oil collection tank 2, and the second support device is installed on the vessel 1. The second support device is connected to the oil containment device to deploy the oil containment device (oil boom) to contain and guide the spilled oil.

[0032] The oil containment device includes a third support and an oil containment boom. The third support is fixedly mounted on the oil collection tank 2 and hinged to the oil containment boom to adjust its forward tilt angle. The third support includes a support tube 11, a third support seat 12, a first linear actuator 13, and an oilcloth component. The support tube 11 is rectangular and one side wall is vertically fixed on the oil collection tank 2 to support the oilcloth component. The third support seat 12 is C-shaped, and a rotating hole is provided on the outer side of the groove bottom. The third support seat 12 is rotatably mounted on a rotating shaft on the other side wall of the support tube 11 through the rotating hole, allowing it to tilt forward (towards the bow) through the rotating hole and the rotating shaft. The bottom end of the first linear actuator 13 is horizontally fixed on the oil collection tank 2, and the top end of the first linear actuator 13 is hinged to the top end of the third support seat 12 via a first transmission rod 14. The first transmission rod 14 is generally right-angled, with one end vertically fixed to the top of the first linear actuator 13, and the other end hinged to the top of the third support base 12. The oilcloth assembly is disposed inside the support pipe 11 to seal the gap between the support pipe 11 and the third support base 12, preventing oil spillage from leaking between them. When the first linear actuator 13 shortens, it pulls the top of the third support base 12 forward towards the bow, adjusting the forward tilt angle of the oil boom assembly.

[0033] The oilcloth component includes a rotating shaft 15 and an oilcloth 16. The rotating shaft 15 is rotatably disposed inside the support tube 11. A torsion spring is sleeved on one end of the rotating shaft 15. One end of the torsion spring is fixedly connected to the rotating shaft 15, and the other end of the torsion spring is fixedly connected to the inner wall of the support tube 11. One end of the oilcloth 16 is fixedly connected and wound around the rotating shaft 15. The other end of the oilcloth 16 passes through a long through hole on the third side wall of the support tube 11 and is fixedly connected to the side wall of the third support seat 12 to cover the gap between the support tube 11 and the third support seat 12 (especially to cover the gap between the third support seat 12 and the support tube 11 when the third support seat 12 is tilted forward, preventing oil spillage from leaving through this gap).

[0034] The oil containment boom includes an oil containment boom 17 and a lifting component. One end of the oil containment boom 17 is provided with a first slider 18. One end of the oil containment boom 17 is axially slidably fitted into the groove of the third support seat 12 through the first slider 18. The other end of the oil containment boom 17 is connected to the second support component. The lifting component is provided on the oil containment boom 17 to adjust the depth of the bottom of the oil containment boom 17 below the sea surface.

[0035] The lifting mechanism includes a counterweight pipe 19, buoyancy balls 20, branch pipes, a main pipe, and an air pump. One end of the counterweight pipe 19 is vertically fixed to the bottom edge of the oil boom 17. Multiple counterweight pipes 19 are spaced apart along the direction of the oil boom 17. Each buoyancy ball 20 is connected to the bottom end of the counterweight pipe 19, with each buoyancy ball 20 corresponding to one of the counterweight pipes 19. One end of each branch pipe is connected to the top end of the counterweight pipe 19, with each branch pipe corresponding to one of the counterweight pipes 19. One end of each main pipe is connected to the other end of one of the branch pipes, and the other end of the main pipe is connected to the air pump installed on the vessel 1.

[0036] Furthermore, the counterweight pipe 19 is made of a seawater-resistant metal material. Alternatively, the counterweight pipe 19 can be made of lead or stainless steel to increase weight and adjust the depth at which the bottom of the oil boom 17 sinks into the seawater. A drain hole is provided on the lower side of the buoyancy ball 20, located at the lowest point of the buoyancy ball 20. When the buoyancy ball 20 sinks into the seawater, seawater will enter the buoyancy ball 20 to reduce its buoyancy, thereby increasing the depth at which the bottom of the oil boom 17 sinks into the seawater. When the air pump pressurizes the buoyancy ball 20 through the main pipe and the branch pipe, seawater will be discharged from the buoyancy ball 20 through the drain hole to increase its buoyancy, thereby reducing the depth at which the bottom of the oil boom 17 sinks into the seawater. Alternatively, the buoyancy ball 20 can also be a balloon with expansion and contraction, the balloon having a fully enclosed structure. When the air pump pressurizes the buoyancy ball 20 through the main pipe and the branch pipe, the volume of the balloon will increase, thereby increasing the buoyancy of the buoyancy ball 20. Furthermore, the buoyancy ball 20 in this case is a rubber sealing bladder (made of neoprene rubber, ethylene propylene rubber or fluororubber) that is resistant to seawater corrosion.

[0037] The second support component includes a boom component and a buoy component. The boom component is mounted on the vessel 1 to adjust the deployment range of the oil boom 17 via the connected buoy component. The boom component includes a second power component 21 and a boom 22. The second power component 21 is mounted on the deck of the vessel 1 to drive the connected boom 22 to pitch, swing back and forth, and extend and retract.

[0038] The pontoon assembly includes a pontoon 23, a fourth support base 24, and a second linear actuator 25. The pontoon 23 is mounted on the free end of the boom 22. The fourth support base 24 has the same structure as the third support base 12. The fourth support base 24 is rotatably mounted on a rotating shaft 15 on the pontoon 23 through a rotating hole, allowing the fourth support base 24 to tilt inward (towards the hull) at one end of the oil boom 17 on the pontoon 23. The sliding groove of the fourth support base 24 is slidably mounted on a second slider 26 at the other end of the oil boom 17, allowing the oil boom 17 to slide up and down on the fourth support base 24 via the second slider 26, thereby adjusting the diving depth of the bottom edge of the oil boom 17. The second linear actuator 25 is fixedly mounted on the pontoon 23, and the top end of the second linear actuator 25 is hinged to the top end of the fourth support base 24 via a second transmission rod 27 to push the fourth support base 24 inward.

[0039] When the first linear actuator shortens to the predetermined position and stops (at which time the second linear actuator extends in coordination), it will cause the top of the third support to tilt forward. The third support will then cause the top of the oil boom 17 to tilt forward through the first slider. At this time, the bottom of the oil boom and the counterweight pipe will tilt backward in the seawater. That is, by reducing the angle between the oil boom 17 and the sea surface, the water flow resistance is significantly reduced, and the ship speed and oil recovery efficiency are improved (this mode is suitable for when the wind and waves are small).

[0040] When the first linear actuator extends to the predetermined position and stops (at which point the second linear actuator retracts), it will cause the top of the third support to tilt backward. The third support, through the first slider, will cause the top of the oil boom 17 to tilt backward. At this time, the bottom of the oil boom and the counterweight pipe tilt forward in the seawater. That is, by increasing the facing angle between the oil boom 17 and the sea surface in front, wind resistance is significantly reduced, and because the counterweight pipe is submerged to a greater depth in the sea, the reliability of oil recovery under large waves is significantly improved.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
