Abstract
Description
Technical Field
[0001] This utility model relates to an energy-saving flow guiding device, and in particular to a ship hydrodynamic energy-saving flow guiding device applied in the field of shipbuilding. Background Technology
[0002] With the gradual emergence of the global energy crisis, international oil prices have been fluctuating upwards since the beginning of the 21st century, resulting in persistently high shipping costs. Therefore, reducing operating costs has become a common challenge for the shipping industry. At the same time, various environmental problems caused by greenhouse gas emissions are becoming increasingly serious and have attracted widespread attention from the international community. As a result, the research and development of ship hydrodynamic energy-saving devices has become a major topic in the field of ship research and has also gained favor among ship owners.
[0003] Chinese Patent Publication No. CN220076651U discloses an energy-saving device for a ship's hydrodynamic front guide wheel. This utility model uses an integrated molding of a front guide tube and an inner guide vane in conjunction with the use of an installation shaft. By inserting the installation shaft from the front, the connecting protrusion on the inner side of the inner guide vane is engaged in a fixing groove opened on the outside of the installation shaft. From the rear, a fixing flange is fixed to the rear side of the installation shaft, and then connecting bolts are used to penetrate the fixing flange and install it inside the fixing hole to limit the connecting protrusion, thereby achieving the connection between the inner guide vane and the installation shaft. By connecting the installation shaft to the hull boss with bolts, the front guide tube and the inner guide vane can be disassembled, facilitating their later maintenance and replacement.
[0004] However, the above-mentioned patents still have the following problems in practical applications: the inner and outer guide vanes in the above-mentioned patents are fixed at angles after installation. However, in actual ship applications, the angle of the guide vanes needs to be changed according to different conditions such as ship speed, load conditions and water environment. For example, when the ship is traveling at low speed, the angle of the guide vanes needs to be increased to enhance the water flow acceleration effect and make up for the lack of propulsion. When the ship is traveling at high speed, the angle of the guide vanes needs to be decreased to avoid the guide vanes themselves becoming flow field obstacles. The fixed angle of the guide vanes is not convenient for the staff to adjust according to the actual navigation conditions. Utility Model Content
[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the guide vanes in the existing patents are at a fixed angle, which makes it inconvenient for staff to adjust them according to the actual navigation conditions, resulting in reduced flexibility of the energy-saving flow guiding device.
[0006] To address the aforementioned problems, this utility model provides a ship hydrodynamic energy-saving flow guiding device, comprising a pre-conductor, with multiple support seats fixedly connected to its outer surface. Each support seat has an outer blade at its end away from the pre-conductor, and a rotating rod is fixedly connected to the end of the outer blade facing the support seat. Multiple positioning strips, each corresponding to one of the support seats, are fixedly connected to the inner wall of the pre-conductor. The rotating rod, at its end away from the outer blade, sequentially rotatably passes through the support seat, the pre-conductor, and the positioning strips, and is fixedly connected to a positioning block, which is a cube. An inner blade is located at the end of the positioning strip away from the pre-conductor, and an installation strip is rotatably connected to the end of the inner blade away from the positioning strip. An installation shaft is located inside the pre-conductor. An electric slide rail is rotatably fitted onto the outer surface of the pre-conductor, and a corrugated sleeve is also fixedly fitted onto the outer surface of the pre-conductor. The electric slide rail is located inside the corrugated sleeve. An adjusting rod is fixedly fitted onto the outer surface of the rotating rod, and a groove is chiseled on the outer surface of the adjusting rod. Multiple limiting rods, each corresponding to one of the support seats, are slidably fitted onto the outer surface of the electric slide rail. The limiting rods, at their ends away from the electric slide rail, sequentially pass through the corrugated sleeve and movably pass through adjacent grooves.
[0007] In the aforementioned ship hydrodynamic energy-saving flow guiding device, the angles of the outer and inner blades can be adjusted according to the actual navigation conditions, so that the energy-saving flow guiding device can adapt to different conditions such as ship speed, load conditions and water environment, thereby effectively improving the flexibility of the energy-saving flow guiding device, further improving the ship's navigation effect and reducing energy consumption.
[0008] As a further improvement of this application, the pre-catheter, the corrugated sleeve and the electric slide rail are all arc-shaped, and the arc of the electric slide rail is smaller than that of the pre-catheter.
[0009] As a further improvement of this application, the adjusting rod is located inside the support base, the electric slide rail is located on the front side of the support base, and the support base is U-shaped as a whole.
[0010] As a further improvement of this application, the end of the positioning block away from the rotating rod is fixedly inserted through the adjacent inner blade, and the end of the mounting strip away from the inner blade is fixedly connected to the mounting shaft.
[0011] As another improvement of this application, the front end of the mounting shaft is chiseled with multiple positioning grooves that correspond to multiple mounting strips respectively. The end of the mounting strip away from the inner blade is fixedly connected with a retaining strip, which is located in the adjacent positioning groove. The front end of the mounting shaft is provided with a positioning ring, and the positioning ring is fixedly connected to the mounting shaft by multiple screws.
[0012] As a further improvement to this application, the end of the positioning block away from the rotating rod moves through the adjacent inner blade, and the locking strip matches the positioning groove perfectly.
[0013] In summary, in practical applications, if it is necessary to adjust the angles of the outer and inner blades, the electric slide rail can be started to rotate clockwise or counterclockwise, causing the limit rod to rotate, which in turn drives the adjusting rod to rotate, causing the rotating rod to rotate. The outer blades and positioning blocks connected to the rotating rod also change angle accordingly. The positioning block then drives the inner blades to rotate synchronously, so that multiple outer and inner blades rotate simultaneously. This allows the energy-saving flow guiding device to be adjusted according to different conditions during ship navigation, effectively improving the flexibility of the energy-saving flow guiding device, further improving the ship's navigation effect, and reducing energy consumption.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0025] First implementation method:
[0026] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shows a ship hydrodynamic energy-saving flow guiding device, including a pre-conductor 1. Multiple support seats 2 are fixedly connected to the outer surface of the pre-conductor 1. The support seats 2 can support and limit the outer blades 3 and rotating rods 4. The support seats 2 are generally U-shaped. An outer blade 3 is provided at the end of the support seat 2 away from the pre-conductor 1. A rotating rod 4 is fixedly connected to the end of the outer blade 3 facing the support seat 2. Multiple positioning strips 5, each corresponding to a different support seat 2, are fixedly connected to the inner wall of the pre-conductor 1. The end of the rotating rod 4 away from the outer blade 3 rotates sequentially through the support seats. The seat 2, the pre-conductor 1, and the positioning strip 5 are fixedly connected to a positioning block 6, which is a cube and can drive the inner blade 7 to rotate. The end of the positioning strip 5 away from the pre-conductor 1 is provided with the inner blade 7. The end of the inner blade 7 away from the positioning strip 5 is rotatably connected to the mounting strip 8. The pre-conductor 1 is provided with a mounting shaft 9. The end of the positioning block 6 away from the rotating rod 4 is fixedly inserted through the adjacent inner blade 7. The end of the mounting strip 8 away from the inner blade 7 is fixedly connected to the mounting shaft 9 to fix the mounting strip 8, thereby indirectly limiting the inner blade 7.
[0027] Figure 3 , Figure 4 , Figure 5 and Figure 6 The diagram shows that an electric slide rail 10 is rotatably fitted on the outer surface of the pre-conduit tube 1. Those skilled in the art can select a suitable model of electric slide rail 10 according to actual needs, such as RPD165. A corrugated sleeve 14 is also fixedly fitted on the outer surface of the pre-conduit tube 1. The pre-conduit tube 1, the corrugated sleeve 14, and the electric slide rail 10 are all arc-shaped, and the arc of the electric slide rail 10 is smaller than that of the pre-conduit tube 1. The electric slide rail 10 is located inside the corrugated sleeve 14 and rotates within it. The corrugated sleeve 14 protects the electric slide rail 10. An adjusting rod 1 is fixedly fitted on the outer surface of the rotating rod 4. 1. The outer surface of the adjusting rod 11 is chiseled with a groove 12. The support base 2 is U-shaped. The outer surface of the electric slide rail 10 is slidably fitted with multiple limiting rods 13, which are respectively corresponding to multiple support bases 2. The end of the limiting rod 13 away from the electric slide rail 10 is fixedly inserted through the corrugated sleeve 14 and movably inserted through the adjacent groove 12. During the rotation of the electric slide rail 10, the limiting rod 13 also rotates, thereby causing the corrugated sleeve 14 to deform. The limiting rod 13 can drive the adjusting rod 11 to rotate, thereby causing the rotating rod 4 to rotate, and then causing the outer blade 3 and the inner blade 7 to change angle.
[0028] During ship navigation, if it is necessary to adjust the angle of the outer blade 3 and the inner blade 7, the electric slide rail 10 can be activated to rotate clockwise or counterclockwise, causing the limit rod 13 to rotate, which in turn pushes the adjusting rod 11 to rotate, causing the rotating rod 4 to rotate. The outer blade 3 and the positioning block 6 connected to the rotating rod 4 also change their angles accordingly. The positioning block 6 then drives the inner blade 7 to rotate synchronously, so that multiple outer blades 3 and inner blades 7 rotate simultaneously. This allows the energy-saving flow guiding device to be adjusted according to different ship navigation conditions, effectively improving the flexibility of the energy-saving flow guiding device, further improving the ship navigation effect, and reducing energy consumption.
[0029] Second implementation method:
[0030] This embodiment adds a positioning ring 15, a positioning groove 16, and a locking strip 17 to the first embodiment, while the rest remains the same as the first embodiment.
[0031] Figure 7 and Figure 8 As shown: The front end of the mounting shaft 9 is chiseled with multiple positioning grooves 16, each corresponding to a plurality of mounting strips 8. The end of the mounting strip 8 away from the inner blade 7 is fixedly connected to a retaining strip 17, which is located in the adjacent positioning groove 16. The front end of the mounting shaft 9 is provided with a positioning ring 15, which is fixedly connected to the mounting shaft 9 by multiple screws. The end of the positioning block 6 away from the rotating rod 4 moves through the adjacent inner blade 7. The retaining strip 17 and the positioning groove 16 are perfectly matched.
[0032] If the inner blade 7 is damaged and needs to be replaced during ship navigation, the screw can be unscrewed to remove the positioning ring 15, and then the mounting shaft 9 can be pushed backward to make the retaining strip 17 slide out of the positioning groove 16. The staff can then remove the inner blade 7 for maintenance, thereby effectively extending the service life of this energy-saving flow guiding device.
[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
