Description

Technical Field

[0001] This utility model relates to the field of propeller propulsion improvement technology, specifically a device for improving the propulsion efficiency of oil tankers. Background Technology

[0002] In the propulsion system of oil tankers, the propeller is the main propulsion device, responsible for converting the power generated by the engine into the power to propel the ship forward. Propeller design often suffers from problems such as non-smooth flow, eddies and turbulence, resulting in efficiency loss. Traditional propeller systems rely on blades with fixed angles to drive the ship forward. The thrust that propels the ship is usually generated through the interaction between the blades and the water flow. Under standard operating conditions, the efficiency of the propeller depends on the ship's speed, load and marine environment. For different speeds and operating conditions, the fixed blade angle of the propeller cannot provide the optimal propulsion efficiency.

[0003] Ships adapt to different speeds and load conditions by adjusting the angle of their blades. In special circumstances, fixed propeller blades cannot provide sufficient propulsion. Oil tankers typically need to conduct long-term, stable transportation operations under different speeds and operating conditions, which makes the performance of fixed propellers poor. Under these conditions, the technology of adjusting the blade angle can provide a significant improvement in efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a device for improving the propulsion efficiency of oil tankers, which has the advantage of adjusting the angle of the propeller to adapt to different navigation conditions, and solves the problem that the fixed blade angle of the propeller cannot provide the optimal propulsion efficiency.

A fixed hollow column 2 is fixedly connected to the inner cavity of the hull 1, and the other end of the fixed hollow column 2 extends to the outer side of the hull 1. A first motor 3 is fixedly connected to the inner cavity of the hull 1. A first fixed block 4 is fixedly connected to the output end of the first motor 3. A second motor 5 is fixedly connected to the inner cavity of the first fixed block 4. A rotating disk 6 is fixedly connected to the output end of the second motor 5. A first fixed rod 7 is fixedly connected to the surface of the rotating disk 6. A sliding connecting rod 8 is fixedly connected to one end of the first fixed rod 7. A second fixed block 9 is fixedly connected to both ends of the sliding connecting rod 8. A second fixed rod 10 is rotatably connected to the inner cavity of one side of each of the two second fixed blocks 9. A first sliding block 11 is fixedly connected to one side of both second fixed rods 10. A first fixed post 12 is fixedly connected to one side of the fixed block 4. A second fixed post 13 is fixedly connected to the inner cavity of the first fixed post 12. The surface of the second fixed post 13 is slidably connected to the first sliding block 11. A second sliding block 14 is fixedly connected to one side of the first sliding block 11. The second sliding block 14 is slidably connected to the surface of the second fixed post 13. Three third fixed rods 15 are fixedly connected to one side of the second sliding block 14. A moving block 16 is fixedly connected to one side of each of the three third fixed rods 15. A moving rod 17 is rotatably connected to the inner cavity of one side of each of the three moving blocks 16. A propeller blade 18 is fixedly connected to the other end of each of the three moving rods 17. A third fixed block 19 is rotatably connected to one end of each of the three propeller blades 18. The third fixed block 19 is fixedly connected to the surface of one end of the second fixed post 13.

[0021] Specifically, connecting blocks 20 are fixedly connected to both sides of the surface of the first fixed column 12, and two limiting blocks 21 are fixedly connected to the bottom of the two connecting blocks 20. The sliding connecting rod 8 is slidably connected to the inner cavity of the limiting block 21.

[0022] In this embodiment, by using the connecting block 20 and the limiting block 21 together, the sliding link 8 can slide smoothly in the inner cavity of the limiting block 21, thereby increasing the position restriction and stability of the sliding link 8, effectively preventing the sliding link 8 from disengaging or shifting position due to improper operation or external influence, and ensuring that it always runs within the limiting block 21.

[0023] Specifically, a rotating groove is provided at one end of the fixed hollow column 2, and a rotating hollow body 22 is rotatably connected to the inner cavity of the rotating groove. A through groove is provided on the surface of the rotating hollow body 22, and the inner cavity of the through groove is rotatably connected to the propeller blade 18.

[0024] In this embodiment: through the cooperation of the rotating groove and the rotating cavity 22, the rotating cavity 22 can drive the propeller blade 18 to rotate smoothly, thus realizing the propeller propulsion function. The surface of the rotating cavity 22 is provided with through grooves to ensure that the propeller blade 18 can rotate in the inner cavity of the rotating cavity 22, avoiding jamming caused by friction or structural problems.

[0025] Specifically, a first cutting blade 23 is fixedly connected to the surface of one end of the fixed hollow column 2, and a second cutting blade 24 is fixedly connected to the surface of the rotating cavity 22, with the first cutting blade 23 and the second cutting blade 24 in contact.

[0026] In this embodiment, the combined use of the first cutting blade 23 and the second cutting blade 24 can effectively solve the problem of underwater debris entanglement on the propeller blade 18, cut off or decompose the debris stirred around the propeller blade 18, avoid the situation of debris entanglement on the propeller blade, improve work efficiency, and effectively reduce wear and loss caused by debris entanglement.

[0027] Specifically, heat dissipation holes are provided on both sides of the first fixing block 4.

[0028] In this embodiment, the heat dissipation performance of the second motor 5 during operation can be effectively improved by setting heat dissipation holes, reducing overheating problems caused by long-term operation, and making it easier for the heat generated by the second motor 5 during operation to dissipate to the surrounding environment, thereby reducing its temperature and avoiding the effects of overheating.

[0029] The user fixes the device to the stern of the hull 1 of the boat, which is attached to the fixed column 2, and starts the first motor 3. The output end of the first motor 3 is fixedly connected to the second fixed column 13. One end of the second fixed column 13 is fixedly connected to the third fixed block 19, and the surface of the third fixed block 19 is connected to three propeller blades 18 via a rotating shaft. The propeller blades 18 are rotatably connected to the through slots of the rotating cavity 22. When the first motor 3 starts, it drives the third fixed block 19 to rotate, which in turn causes the rotating cavity 22 to drive the propeller blades 18 to rotate, thereby propelling the hull 1 forward. To prevent fishing nets or ropes from getting tangled in the rotating cavity 22 during operation, a second cutting blade 24 is fixed to the surface of the rotating cavity 22, while a first cutting blade 23 is fixed to the surface of the fixed column 2. When the rotating cavity 22 rotates, the first cutting blade 23 contacts the second cutting blade 24, effectively cutting the fishing nets or ropes tangled in the surface of the rotating cavity 22, ensuring the normal operation of the propeller blades 18 and preventing obstacles from affecting propulsion. In addition to improving efficiency, the rotating disk 6 is driven by the second motor 5 inside the first fixed block 4. The rotating disk 6 drives the first fixed rod 7 to rotate. One end of the first fixed rod 7 is fixedly connected to a sliding connecting rod 8. The sliding connecting rod 8 slides inside the cavity of the limiting block 21. The limiting block 21 restricts the position of the sliding connecting rod 8 and prevents it from falling off. The movement of the sliding connecting rod 8 further drives the first sliding block 11 to slide along the surface of the second fixed column 13. One side of the first sliding block 11 is fixedly connected to the second sliding block 14, and three third fixed rods 15 are fixedly connected to the surface of the second sliding block 14. The third fixed rods 15 are fixedly connected to the moving block 16. The inner cavity of the other end of the moving block 16 is rotatably connected to the moving rod 17. The moving rod 17 is fixedly connected to the propeller blade 18. Through the action of the moving rod 17, the propeller blade 18 can rotate on the surface of the third fixed block 19, thereby adjusting the angle of the propeller blade 18. The angle of the propeller blade 18 can be automatically adjusted according to different navigation conditions to optimize propulsion efficiency and improve the navigation performance of the oil tanker.
