In the face of the above problems, it is often necessary to manually clean up the entanglements after stopping the ship. Such operations are time-consuming and laborious, and frequent manual intervention increases maintenance costs. Summary of the invention

[0026] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0027] Combination Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses an anti-entanglement marine propeller, comprising: a screw shaft 12, a propeller 11, a motor 13, a drive shaft 14, a primary cutting assembly 2, and a secondary cutting assembly 3. The screw shaft 12 is fixedly connected to the driving device of the hull; the propeller 11 is fixedly connected to the screw shaft 12; the motor 13 is fixedly arranged at one end of the screw shaft 12; the drive shaft 14 is fixedly connected to the output shaft of the motor 13; The first-stage cutting assembly 2 is rotatably arranged on the peripheral side of the driving shaft 14, and is used for cutting the windings on the outside of the spiral shaft 12; the second-stage cutting assembly 3 is slidably arranged on one side of the first-stage cutting assembly 2, and is used for further cutting the windings on the outside of the spiral shaft 12; wherein, a cavity 15 for the driving shaft 14 to rotate is arranged in the spiral shaft 12, and the first-stage cutting assembly 2 is arranged on one side of the propeller 11.

[0028] In the embodiment of the present application, the screw shaft 12 and the drive shaft 14 are arranged in a cylindrical shape. It should be noted that the diameter of the drive shaft 14 is smaller than the diameter of the screw shaft 12, and the length of the drive shaft 14 is smaller than the length of the screw shaft 12. The material of the drive shaft 14 and the screw shaft 12 can be stainless steel or alloy steel, as long as it is corrosion-resistant. The screw shaft 12 is connected to the hull for rotation, and its power is provided by the hull. The connection between the propeller 11 and the screw shaft 12 and the hull is common knowledge known to those skilled in the art, so the embodiment of the present application will not be elaborated in detail.

[0029] When in use, the motor 13 is started, so that the motor 13 drives the driving shaft 14 to rotate. When the driving shaft 14 rotates, it drives the primary cutting assembly 2 to cut the windings around the spiral shaft 12. At the same time, when the primary cutting assembly 2 extends out of the spiral shaft 12 and cuts the windings wound on the outside of the spiral shaft 12, the secondary cutting assembly 3 further cuts the windings wound on the outside of the spiral shaft 12, wherein the cutting direction of the secondary cutting assembly 3 is perpendicular to the cutting direction of the cutting assembly. Since the spiral shaft 12 drives the propeller to rotate, the windings will fall off with the rotation of the spiral shaft 12 after being cut. This saves time and effort compared to manually cleaning the windings after stopping the voyage.

[0030] Combination Figure 2 and Figure 3In a specific embodiment, the first-stage cutting assembly 2 includes a first gear 21, a turntable 22, and a cutting piece 23. The first gear 21 is fixedly arranged on the peripheral side of the driving shaft 14; the axis of the turntable 22 is rotatably connected to the side wall of the cavity 15, and the outer peripheral side of the turntable 22 is meshed with the first gear 21; the cutting piece 23 is rotatably arranged on the inner peripheral side of the turntable 22, and a tooth groove 24 is arranged on the inner peripheral side of the turntable 22. Among them, the cutting member 23 includes a second gear 231, a rack 232, and a primary cutting plate 233. The second gear 231 is meshed with the tooth groove 24, and the axis of the second gear 231 is rotatably connected to the side wall of the cavity 15; the rack 232 is meshed with the second gear 231, and the rack 232 slides with the side end of the turntable 22; one end of the primary cutting plate 233 is fixedly set on the rack 232, and a blade is set at one end of the primary cutting plate 233 close to the side wall of the cavity 15; wherein, an opening for the primary cutting plate 233 to move is set on the peripheral side of the spiral shaft 12.

[0031] In the embodiment of the present application, the first gear 21 is fixedly arranged on the circumference of the driving rod 35. The first gear 21 can be integrally formed and fixed on the circumference of the driving rod 35 or fixed by welding or bonding. An engagement groove is provided at one end of the turntable 22 close to the second gear 231, so that the turntable 22 is engaged with the second gear 231, that is, the axis of the turntable 22 is perpendicular to the axis of the driving rod 35. The axis of the second gear 231 is perpendicular to the axis of the driving rod 35, and the second gear 231 is connected to the side wall of the cavity 15 by a bearing or a rotating shaft. The rack 232 is engaged with the second gear 231. When the second gear 231 rotates, the rack 232 slides along the side end of the turntable 22, that is, the rack 232 moves linearly along the diameter direction of the turntable 22. The primary cutting plate 233 is arranged in a fan shape, and a blade is provided on the arc portion, wherein one edge of the primary cutting plate 233 is parallel to the rack 232. It should be noted that the primary cutting plate 233 can be integrally formed or fixedly arranged on the rack 232 by bolting, so that the rack 232 can drive the primary cutting plate 233 to cut when performing linear motion. The cutting member 23 is symmetrically arranged in two groups, and the primary cutting assembly 2 is arranged in two groups, and the two groups of primary cutting assemblies 2 are respectively arranged on both sides of the propeller 11. The primary cutting assembly 2 can increase the cutting effect of the winding outside the screw shaft 12.

[0032] During specific use, start the motor 13, so that the motor 13 drives the driving shaft 14 to rotate, and the driving shaft 14 drives the first gear 21 to rotate. Since the first gear 21 is engaged with the turntable 22, when the first gear 21 rotates, the turntable 22 rotates, and the rotation of the turntable 22 drives the second gear 231 to rotate. At this time, the second gear 231 drives the rack 232 to move in the direction of the spiral shaft 12, so that the first-level cutting plate 233 cuts the winding on the outside of the spiral shaft 12, which is convenient and quick.

[0033] Combination Figure 3 , Figure 4 and Figure 5 In a specific embodiment, a movable groove 25 is horizontally provided at one end of the rack 232 away from the second gear 231, and the secondary cutting assembly 3 includes a secondary cutting plate 31, a first spring 32, a slider 33, a second spring 34, and a driving rod 35. A matching groove 36 is horizontally provided at one end of the rack 232 away from the second gear 231, and the matching groove 36 is correspondingly arranged with the movable groove 25, and a mounting groove 37 is vertically provided on the rack 232; the secondary cutting plate 31 is slidably arranged in the movable groove 25, and a blade is provided at one end of the secondary cutting plate 31 away from the movable groove 25; one end of the first spring 32 is fixedly connected to the bottom of the movable groove 25, and the other end of the first spring 32 is fixedly connected to one end of the secondary cutting plate 31 close to the bottom wall of the movable groove 25.

[0034] The slider 33 is slidably set in the matching groove 36; one end of the second spring 34 is fixedly connected to the bottom wall of the matching groove 36, and the other end of the second spring 34 is fixedly connected to one end of the slider 33 close to the matching groove 36; the driving rod 35 is slidably set in the installation groove 37, one end of the driving rod 35 is fixedly connected to the slider 33, and the other end of the driving rod 35 is fixedly connected to the secondary cutting plate 31; wherein, the two sides of the installation groove 37 are respectively connected to the matching groove 36 and the movable groove 25.

[0035] In a specific embodiment, the secondary cutting plate 31 is arranged in an arc shape, and the slider 33 is arranged in a rectangular shape. It should be noted that a guide slope is arranged at one end of the slider 33 away from the bottom of the matching groove 36. The driving rod 35 is arranged in a rectangular plate shape, and the length of the driving rod 35 is sufficient to connect the slider 33 with the secondary cutting plate 31. The matching groove 36, the moving groove 25 and the installation groove 37 are all arranged in a rectangular shape. It should be noted that the installation groove 37 connects the matching groove 36 and the moving groove 25. When used specifically, when the rack 232 moves toward one end of the driving rod 35, the rack 232 drives the slider 33 and the secondary cutting plate 31 to move. When the matching groove 36 is higher than the outer wall of the driving rod 35, the second spring 34 drives the slider 33 to slide toward the end away from the matching groove 36 due to its elastic recovery ability. At the same time, the slider 33 drives the driving rod 35 to move during the sliding process, and then the driving rod 35 drives the secondary cutting plate 31 to move, and the winding material wound on the outer peripheral side of the spiral shaft 12 is further cut along the length direction of the spiral shaft 12. It should be noted that the wall thickness of the screw shaft 12 needs to be such that when the rack 232 contracts, the side wall of the opening abuts against the end of the rack 232 without teeth.

[0036] The implementation principle of the embodiment of the present application is as follows: start the motor 13, so that the motor 13 drives the drive shaft 14 to rotate, and the drive shaft 14 drives the primary cutting assembly 2 to cut the winding material around the spiral shaft 12 when rotating, and at the same time, the motor 13 drives the drive shaft 14 to rotate, and the drive shaft 14 drives the first gear 21 to rotate. Since the first gear 21 is meshed with the rotating disk 22, when the first gear 21 rotates, the rotating disk 22 rotates, and the rotation of the rotating disk 22 drives the second gear 231 to rotate. At this time, the second gear 231 drives the rack 232 to move in the direction of the spiral shaft 12, so that The primary cutting plate 233 cuts the windings on the outside of the spiral shaft 12. When the rack 232 moves toward one end of the driving rod 35, the rack 232 drives the slider 33 and the secondary cutting plate 31 to move. When the matching groove 36 is higher than the outer wall of the driving shaft 14, the second spring 34 drives the slider 33 to slide toward the end away from the matching groove 36 due to its elastic recovery ability. At the same time, the slider 33 drives the driving rod 35 to move during the sliding process, and then the driving rod 35 drives the secondary cutting plate 31 to move, and the windings wound on the outer peripheral side of the spiral shaft 12 are further cut along the length direction of the spiral shaft 12. Since the spiral shaft 12 drives the propeller to rotate, the windings will fall off with the rotation of the spiral shaft 12 after being cut. This saves time and effort compared to manually cleaning the windings after stopping the flight.

[0037] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
