Description

Technical Field

[0001] This utility model relates to the field of ship propulsion auxiliary equipment technology, and in particular to an energy-saving fairing structure for ships. Background Technology

[0002] During ship navigation, propeller propulsion systems are prone to generating wake vortices due to uneven water flow distribution, leading to increased water flow energy loss. This not only reduces propulsion efficiency but also consumes additional ship power, increasing fuel costs. Therefore, fairings are key components for optimizing the propeller flow field and improving energy efficiency. Existing energy-saving fairing structures for ships are mostly fixed integrated structures. Their internal flow channels and guiding components cannot be adjusted according to propeller speeds, making it difficult to ensure a stable flow field under different propeller operating conditions, resulting in low adaptability. Furthermore, water flow tends to form turbulent vortices at the outlet after passing through the fairing, leading to significant energy loss and reduced energy efficiency. Finally, the lack of a sealing structure at the connection between the fairing and the ship's propulsion system results in insufficient sealing, making water leakage easy and reducing connection stability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-4 The present invention provides an embodiment of an energy-saving fairing structure for ships, comprising a fairing body 1 and a fairing ring 2, wherein an adjustment component 3 for improving adaptability is connected to the inner wall of the rear end of the fairing body 1.

[0030] The adjustment component 3 includes a fixing ring 4. The outer wall of the fixing ring 4 is fixedly sleeved on the inner wall of the rear end of the guide shield body 1. An annular groove 5 is provided inside the fixing ring 4 to provide a sliding track. The guide ring 2 slides inside the annular groove 5, limiting the movement trajectory.

[0031] The adjusting assembly 3 also includes a fixing plate 6, both ends of which are fixedly connected to the inner wall of the rear end of the guide ring body 1, providing an installation base. The fixing plate 6 is located at the rear end of the fixing ring 4. A threaded hole 7 is opened inside the fixing plate 6, and an adjusting rod 8 is threadedly connected inside the threaded hole 7 to realize the position adjustment of the guide ring 2. One end of the adjusting rod 8 is fixedly connected to a rotating block 9, providing a force point for the operator to easily rotate the adjusting rod 8. The fixing plate 6, adjusting rod 8, and rotating block 9 are all made of stainless steel to ensure strength and corrosion resistance. The other end of the adjusting rod 8 away from the rotating block 9 passes through the threaded hole 7 and is rotatably connected to a connecting plate 10 to transmit power. The connecting plate 10 is fixedly connected to the rear end of the guide ring 2. Multiple sets of guide holes 11 are provided, and guide rods 12 are slidably connected inside each set of guide holes 11. Both ends of the guide rods 12 are fixedly connected to the inner side of the annular groove 5, providing guidance and support for the sliding of the guide ring 2, ensuring that the guide ring 2 moves smoothly and accurately. An arc-shaped guide plate 13 is fixedly connected to the inner side of the guide ring 2. There are three sets of arc-shaped guide plates 13, which can sort the water flow and optimize the water flow direction. An elastic sealing gasket 14 is fixedly connected to the front end of the guide cover body 1 to prevent water leakage. The elastic sealing gasket 14 is made of nitrile rubber. The side of the elastic sealing gasket 14 away from the guide cover body 1 has anti-slip texture 15 to increase friction. The guide cover body 1 is a trumpet shape with a wide front end and a narrow rear end.

[0032] Working principle: The guide shield body 1 is flared, wider at the front and narrower at the rear, which can initially guide the water flow to the propeller in a stable manner. The elastic sealing gasket 14 at the front end can enhance the sealing with the ship's propulsion system and prevent water leakage. The anti-slip texture 15 on the outside increases the friction to improve the connection stability and prevent slippage at the docking point. When the flow field needs to be adjusted according to the propeller speed, the operator rotates the rotating block 9, which drives the adjusting rod 8 to rotate and move back and forth in the threaded hole 7 of the fixed plate 6. The adjusting rod 8 transmits power to the guide ring 2 through the connecting plate 10 connected to the end, so that the guide ring 2 slides along the annular groove 5 inside the fixed ring 4. At the same time, the guide hole 11 on the guide ring 2 slides and engages with the guide rod 12 inside the annular groove 5, providing precise guidance and support for the guide ring 2 and preventing it from deviating during adjustment. Finally, the guide ring 2, adjusted to the appropriate position, further sorts the water flow and optimizes the direction through the inner arc-shaped guide plate 13, reducing wake vortices and energy loss, and achieving stable flow field adaptation under different propeller speeds, thus achieving energy saving and improved propulsion efficiency.
