Description

Technical Field

[0001] The utility model relates to the technical field of stern shaft anti-winding, in particular to a stern shaft anti-winding structure. Background Art

[0002] The stern shaft plays a key role in the ship. It connects the main engine and the propeller and is located at the rear of the hull. The main engine transmits power to the stern shaft through the transmission system, and the stern shaft transmits power to the propeller to propel the ship forward in the water. The effective operation of this transmission system ensures the propulsion efficiency and navigation ability of the ship.

[0003] The anti-entanglement structure of the stern shaft usually includes several key components or mechanisms. The first is the diverter or guide groove, which is located around or above the stern shaft. Its function is to guide floating debris or seaweed in the water to prevent them from contacting the stern shaft. The second is the rotating brush or scraper installed around the stern shaft. These brushes or scrapers can rotate or cooperate with the movement of the stern shaft to effectively prevent floating objects from being entangled on the surface of the stern shaft. In addition, the retractable hood or cover can automatically adjust its position and size according to the water flow and the movement of the stern shaft, effectively preventing floating objects from entering the stern shaft area. There are also automatic cleaning devices, such as robotic arms or water spray devices, which are used to clean floating objects around the stern shaft regularly or as needed to ensure that the stern shaft remains clean.

[0004] However, the cleaning mechanism in the traditional stern shaft anti-entanglement structure is relatively simple and cannot effectively clean the stern shaft, which may cause floating objects to accumulate around the stern shaft for a long time. The accumulated floating objects may cause the stern shaft to rotate unbalanced or increase the running resistance, thereby affecting the propulsion efficiency and fuel consumption of the ship. Therefore, a stern shaft anti-entanglement structure is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a stern shaft anti-winding structure, including a hollow plate 1 and a connecting bent plate 15, a first motor 10 is fixedly connected inside the hollow plate 1, a connecting plate 11 is fixedly connected to the output end of the first motor 10, a connecting rod 9 is rotatably connected to the side wall of the connecting plate 11, a slide groove 4 is fixedly connected inside the hollow plate 1, a fixed block 8 is slidably connected inside the slide groove 4, a side wall of the fixed block 8 is fixedly connected to one end of the connecting rod 9, a sleeve 5 is fixedly connected to the side wall of the fixed block 8, a bristle brush 6 is fixedly connected to the inner wall of the sleeve 5, and a first fixing column 7 is provided at one end of the bristle brush 6.

[0032] Specifically, when the stern shaft anti-winding structure is used, the output end of the first motor 10 first drives the connecting plate 11 to rotate, and the connecting plate 11 transmits the motion to the fixed block 8 through the side wall connecting rod 9, so that it moves in the slide groove 4. In this process, the outer wall of the fixed block 8 slides, causing the side wall sleeve 5 to move accordingly, and the movement of the sleeve 5 drives the bristle brush 6 on the inner wall to move at the same time, effectively cleaning and maintaining the surface of the first fixed column 7. The cleaning around the stern shaft is ensured, the reliability and operation efficiency of the stern shaft system are improved, and the ship or similar equipment is ensured to always maintain efficient operation and stability during operation.

[0033] Reference Figure 1 and Figure 3 A second bevel gear 20 is fixedly connected to the bottom of the hollow plate 1, a collar 18 is fixedly connected to the outer wall of the second bevel gear 20, a support plate 19 is fixedly connected to the bottom of the connecting bent plate 15, a first stepper motor 2 is fixedly connected to the side wall of the support plate 19, a second fixed column 16 is fixedly connected to the output end of the first stepper motor 2, a first bevel gear 17 is fixedly connected to the outer wall of the second fixed column 16, a second stepper motor 14 is fixedly connected to the side wall of the other support plate 19, the output end of the second stepper motor 14 is fixedly connected to the side wall of the support plate 19, the second bevel gear 20 is meshed with the first bevel gear 17, and the outer wall of the second fixed column 16 is rotatably connected to the side wall of the support plate 19.

[0034] Specifically, the second fixed column 16 is driven to rotate by the output end of the first stepper motor 2, and the movement of the second fixed column 16 is transmitted through the first bevel gear 17 on the outer wall, so that the first bevel gear 17 starts to rotate. The first bevel gear 17 interacts with the meshing second bevel gear 20, thereby driving the second bevel gear 20 to rotate at the same time. Then, the output end of the second stepper motor 14 drives the support plate 19 to rotate, and the movement of the support plate 19 drives the connecting bent plate 15 of the side wall to rotate synchronously. The rotation of the connecting bent plate 15 causes the collar 18 to start rotating, thereby realizing multi-directional rotation of the overall structure. It can effectively cope with application scenarios that require frequent adjustment of posture or direction, and provides high flexibility and reliability for complex rotation operations.

[0035] Reference Figure 1 and Figure 2 A driving assembly is arranged inside the hollow plate 1, and the driving assembly is used to drive the propeller 3 to rotate.

[0036] Specifically, the coupling 13 is driven to rotate by the output end of the first stepless motor 12, and the power of the coupling 13 is transmitted to the first fixed column 7 at one end, which then drives the first fixed column 7 to start rotating. The rotation of the first fixed column 7 causes the propeller 3 connected to one end thereof to start rotating synchronously, thereby effectively providing power to drive the propeller 3. It is ensured that the propeller 3 can reliably obtain sufficient power to support the propulsion operation of a ship or similar equipment.

[0037] Working principle: when using the stern shaft anti-winding structure, firstly, the connecting plate 11 is driven to rotate by the output end of the first motor 10, and the force rotation of the connecting plate 11 drives the connecting rod 9 of the side wall to rotate, and the connecting rod 9 drives the fixed block 8 to move, and at the same time, the outer wall of the fixed block 8 slides inside the slide groove 4, and the movement of the fixed block 8 drives the sleeve 5 of the side wall to move, and the movement of the sleeve 5 drives the hard brush 6 on the inner wall to move together, and at the same time, the movement of the hard brush 6 causes one end of it to slide on the outer wall of the first fixed column 7, thereby achieving the effect of cleaning the first fixed column 7, and then the coupling 13 is driven to rotate by the output end of the first stepless motor 12, and the rotation of the coupling 13 drives the first end The fixed column 7 is driven to rotate, and at the same time, the rotation of the first fixed column 7 rotates the propeller 3 at one end, thereby achieving the effect of driving the propeller 3 to rotate, and then the second fixed column 16 is driven to rotate through the output end of the first stepper motor 2, and the rotation of the second fixed column 16 drives the first bevel gear 17 of its outer wall to rotate, and the rotation of the first bevel gear 17 drives the second bevel gear 20 meshing therewith to rotate, and then the support plate 19 is driven to rotate again through the output end of the second stepper motor 14, and the rotation of the support plate 19 drives the connecting bent plate 15 of the side wall to rotate together, and the rotation of the connecting bent plate 15 drives the collar 18 to rotate, thereby achieving the effect of multi-directional rotation.
