Description

Technical Field

[0001] This invention relates to the field of ship propeller components, and in particular to a ship propeller flow-guiding energy-saving rectifier device. Background Technology

[0002] During ship navigation, the propeller, as the core propulsion component, directly affects the ship's navigation performance and energy consumption. Currently, when ship propellers are in operation, water flow passing over them easily generates turbulent flow fields, including eddies and backflow. These disordered flow patterns waste propulsive energy, increase ship drag, and reduce propulsive efficiency, leading to increased fuel consumption. This does not meet the current shipbuilding industry's demand for energy conservation and high efficiency.

[0003] To improve the flow field, existing technologies have applied related flow guiding devices, but these devices mostly adopt a fixed structural design, and the flow guiding angle and rectification shape cannot be flexibly adjusted according to actual working conditions such as ship speed, load changes, and sea state differences. Summary of the Invention

[0004] The main objective of this invention is to provide a ship propeller flow guiding energy-saving rectification device that can effectively solve the problem that traditional devices cannot adjust the flow direction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A ship propeller-guided energy-saving rectifier includes a propeller body, a drive connecting shaft fixedly connected to the rear of the propeller body, the drive connecting shaft being connected to an external drive device, a rotating support seat rotatably connected to the outside of the drive connecting shaft, and a flow guiding and adjusting assembly fixedly connected to the outside of the rotating support seat.

[0013] 1.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, this invention provides a ship propeller flow-guiding energy-saving rectification device, including a propeller body 1, a drive connecting shaft 4 fixedly connected to the rear of the propeller body 1, the drive connecting shaft 4 being connected to an external drive device, a rotating support 3 rotatably connected to the outer side of the drive connecting shaft 4, and a flow-guiding adjustment assembly 2 fixedly connected to the outer side of the rotating support 3. The flow-guiding adjustment assembly 2 drives the adjustment blades 212 to adjust the angle through an internal transmission structure, thereby optimizing the water flow around the propeller body 1. The rotating support 3 is sleeved on the outer side of the drive connecting shaft 4 and rotatably connected to it. On the one hand, it provides stable rotational support for the flow-guiding adjustment assembly 2, ensuring the structural stability of the flow-guiding adjustment assembly 2 when it and the propeller body 1 work together. On the other hand, it does not affect the normal transmission of the drive connecting shaft 4. One end of the drive connecting shaft 4 is fixedly connected to the propeller body 1, and the other end is connected to the external drive device, transmitting external power to the propeller body 1 to drive its rotation and propulsion, while providing an installation carrier for the rotating support 3.

[0023] like Figure 2As shown, this invention provides a ship propeller flow-guiding energy-saving rectification device. The flow-guiding adjustment assembly 2 includes a power mounting base 21, a drive motor 22 fixedly connected to the top of the power mounting base 21, a universal coupling 23 fixedly connected to the front of the output shaft of the drive motor 22, and a telescopic transmission sleeve 24 fixedly connected to the other end of the universal coupling 23. A sliding transmission shaft 25 is slidably connected to the inner side of the telescopic transmission sleeve 24. The universal coupling 23 connects the output shaft of the drive motor 22 and the telescopic transmission sleeve 24, which can compensate for the installation deviation and angular offset between the two connected components, realize flexible power transmission, and avoid transmission jamming caused by assembly errors. The drive motor 22 is fixedly installed through the power mounting base 21. After starting, the output rotational power is transmitted to the telescopic transmission sleeve 24 after the universal coupling 23 compensates for the deviation. The telescopic transmission sleeve 24 and the sliding transmission shaft 25 achieve axial flexible power transmission through sliding cooperation, ensuring stable power delivery to the subsequent multi-stage transmission structure and providing continuous power for blade angle adjustment.

[0024] like Figure 3 As shown, this invention provides a ship propeller flow guiding energy-saving rectification device. A universal coupling 26 is rotatably connected to one end of a sliding transmission shaft 25 away from the telescopic transmission sleeve 24. A driven gear shaft 27 is fixedly connected to the other end of the universal coupling 26. A fixed support frame 28 is rotatably connected to the front of the driven gear shaft 27. A transmission gear ring 210 meshes with the outer side of the driven gear shaft 27. A linkage sleeve 29 is fixedly connected to the inner side of the transmission gear ring 210. The linkage sleeve 29 is located on the fixed support frame 28. Between the sliding transmission shaft 25 and the rotating support 3, and in rotational engagement with the fixed support frame 28, the power transmitted by the sliding transmission shaft 25 is smoothly delivered to the driven gear shaft 27 via the universal coupling 26. The driven gear shaft 27 rotates under the support of the fixed support frame 28, and its outer gear meshes with the transmission gear ring 210. Through gear transmission, it drives the transmission gear ring 210 and the inner fixed linkage sleeve 29 to rotate synchronously, realizing the conversion of power from shaft transmission to ring transmission, and providing power for the push and pull movement of the angle adjustment linkage 215.

[0025] like Figure 4 As shown, the present invention provides a ship propeller flow guiding energy-saving rectification device. A flow guide plate 211 is fixedly connected to the outside of the fixed support frame 28. A flow guide cover is provided on the outside of the flow guide plate 211. An adjusting blade 212 is rotatably connected to the front of the flow guide plate 211. The flow guide plate 211 is fixed to the outside of the fixed support frame 28 and is distributed in a ring shape. It provides an initial flow guiding path for the water flow, guides the water flow along a preset direction, and initially regulates the flow field. The flow guide cover wrapped around the outside of the flow guide plate 211 forms a closed flow guiding channel to avoid water leakage and enhance the rectification effect. At the same time, it protects the internal flow guide blades from the impact of external debris.

[0026] like Figure 5As shown, this invention provides a ship propeller flow guiding energy-saving rectification device. A connecting rod joint 214 is rotatably connected to the outer side of the linkage sleeve 29. An angle adjusting connecting rod 215 is rotatably connected above the connecting rod joint 214. A sliding groove is provided below the adjusting blade 212 and slides in cooperation with the angle adjusting connecting rod 215. A limiting retaining ring 216 is provided on the outer side of the adjusting blade 212 of the angle adjusting connecting rod 215. The rotation of the linkage sleeve 29 drives the connecting lug 213 to deflect. The connecting lug 213 drives the connecting rod joint 214 to swing, thereby driving the angle adjusting connecting rod 215 to perform linear push-pull motion. The upper end of the angle adjusting connecting rod 215 slides in the sliding groove of the adjusting blade 212, converting the push-pull motion into the rotational motion of the adjusting blade 212, thereby realizing the adjustment of the flow guiding angle.

[0027] The working principle of this ship's propeller-guided energy-saving rectifier will be explained in detail below.

[0028] like Figure 1-5 As shown, when the flow direction needs to be adjusted according to the working conditions during the ship's navigation, the drive motor 22 installed on the power mounting base 21 starts. The output shaft of the drive motor 22 drives the universal coupling 23 to rotate, transmitting power to the telescopic transmission sleeve 24. The telescopic transmission sleeve 24 achieves flexible power transmission through sliding engagement with the sliding transmission shaft 25, and then transmits torque to the driven gear shaft 27 through the universal coupling 26, driving the driven gear shaft 27 to rotate around the rotation fulcrum of the fixed support frame 28. When the driven gear shaft 27 rotates, its outer gear structure meshes with the transmission gear ring 210, driving the linkage sleeve 29 fixedly connected to the inner side of the transmission gear ring 210 to rotate synchronously through gear transmission. At the same time, the linkage sleeve 29 is located between the fixed support frame 28 and the rotating support seat 3, maintaining rotational engagement with the fixed support frame 28 to ensure transmission stability. During the rotation of the linkage sleeve 29, its outer connecting lug 213 drives the connecting rod joint 214 to deflect, thereby driving the angle adjustment. The connecting rod 215 performs a push-pull motion; the upper end of the angle adjusting connecting rod 215 is embedded in the groove below the adjusting blade 212, and the push-pull motion is converted into the rotational motion of the adjusting blade 212 through sliding cooperation, so as to achieve precise adjustment of the guiding angle of the adjusting blade 212; at the same time, the limiting ring 216 set on the outside of the angle adjusting connecting rod 215 can effectively limit the rotation stroke of the adjusting blade 212, avoid over-adjustment leading to component disengagement or flow field turbulence, and ensure the reliability of the adjustment process; when the propeller body 1 rotates under the drive connecting shaft 4, and the drive connecting shaft 4 is connected to the external drive device to provide propulsion power for the propeller, when the water flows from rear to front, the adjusting blade 212, which has been adjusted to the appropriate operating angle, cooperates with the guide plate 211 and the guide shroud to sort the water flow around the propeller, effectively suppressing turbulent flow states such as eddies and backflows; by optimizing the flow field structure, reducing water flow energy loss and navigation resistance, improving propeller propulsion efficiency, and ultimately achieving the goal of energy saving and consumption reduction in ships.
