Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0019] For example, see Figure 1 , Figure 2 and Figure 3A marine anchor winch positioning mechanism includes a mounting base plate 1, an anchor winch body 2 is fixedly connected to the mounting base plate 1, the anchor winch body 2 includes a drive shaft 3 fixedly connected to a capstan, a manual locking mechanism 4 is arranged on the drive shaft 3 and the outer side, an auxiliary locking mechanism 5 is arranged on the outer side of the capstan, and the auxiliary locking mechanism 5 cooperates with the side edge of the capstan. The device is fixed on the hull, and when in use, the drive shaft 3 drives the capstan to realize the retraction and release of the anchor chain. The position of the capstan can be locked by the manual locking mechanism 4, and the friction between the anchor chain and the capstan can be adjusted by the auxiliary locking mechanism 5, so as to avoid slipping and avoid causing safety accidents.

[0020] The manual locking mechanism 4 includes a prism shaft 6 fixedly connected to the outside of the driving shaft 3, a horizontal guide rod 7 is slidably connected to the anchor winch body 2, the center line of the horizontal guide rod 7 is parallel to the center line of the driving shaft 3, and a limiting member 8 is fixedly connected to the end of the horizontal guide rod 7. The limiting member 8 is engaged with the edge of the prism shaft 6. A longitudinally movable locking positioning member 9 is also provided on the anchor winch body 2. When the locking positioning member 9 cooperates with the limiting member 8, the limiting member 8 is engaged with the prism shaft 6.

[0021] The position of the limiting member 8 can be changed during the cooperation between the locking positioning member 9 and the limiting member 8. When the locking positioning member 9 slides downward, the limiting member 8 will be lifted up due to the thicker upper part and moved to the outside of the prism shaft 6. The limiting member 8 will engage with the prism shaft 6 to prevent the prism shaft 6 from rotating. At this time, the anchor winch can be fixed.

[0022] A fixing plate 10 is connected to the anchor winch body 2, and a longitudinal guide rod 11 is fixedly connected below the fixing plate 10. The locking limiter 8 is slidably matched with the longitudinal guide rod 11. The locking positioning member 9 is smooth on the side facing the limiter 8 and has different thicknesses. When the thickest position is matched with the limiter 8, the limiter 8 is engaged with the prism shaft 6, and when the thinnest position is matched with the limiter 8, the limiter 8 is disengaged from the prism shaft 6. A first spring 12 for driving the limiter 8 to disengage from the prism shaft 6 is also provided on the outside of the horizontal guide rod 7. When the locking positioning member 9 moves upward, due to the thinner lower half of the locking positioning member 9, the limiter 8 will be disengaged from the engagement state with the prism shaft 6 under the action of the spring force of the first spring 12, and the capstan can rotate normally at this time. Since the locking positioning member 9 moves downward to engage, the engagement state can be effectively and firmly ensured under the dual action of gravity and the spring force of the first spring 12.

[0023] Embodiment 2: This embodiment provides a specific implementation method of the auxiliary locking mechanism 5 based on the previous embodiment. Figure 4 , Figure 5 and Figure 6The auxiliary locking mechanism 5 includes a mounting plate 13, on which a driving unit 14 and a transmission unit 15 are fixedly connected. The side of the capstan facing the auxiliary locking mechanism 5 is a hollow structure, on which a sliding mounting plate 16 is slidably connected. A plurality of limit transverse shifting rods 17 are fixedly connected to the outer side of the sliding mounting plate 16. The limit transverse shifting rods 17 pass through the edge of the capstan and slide with the capstan. A driving guide rod 18 is connected to the other side of the sliding mounting plate 16, and a tilting plate 19 is fixedly connected to the outer end of the driving guide rod 18. The transmission unit 15 is used to drive the tilting plate 19 to move along the direction of the driving guide rod 18, and the driving unit 14 is used to drive the transmission unit 15 to move.

[0024] The driving unit 14 drives the transmission unit 15 to move, so that the tilting plate 19 moves along the direction of the driving guide rod 18, and the limit lateral rod 17 is further exposed from the side edge of the capstan, and the surface roughness is significantly increased, which greatly increases the friction between the anchor chain and the capstan, ensuring the safety of use. When the limit lateral rod 17 moves too much, it will be directly inserted into the anchor chain, which can more effectively avoid the slippage between the anchor chain and the capstan.

[0025] A plurality of second springs 20 are fixedly connected to one side of the sliding mounting plate 16 away from the limiting transverse shifting rod 17. The second springs 20 are fixedly connected to the inner side wall of the winch edge. When the second springs 20 are not subjected to external force, the limiting transverse shifting rod 17 retracts to the inner side of the winch edge.

[0026] The driving unit 14 includes a driving motor 21, and a driving pulley 22 is fixedly connected to the rotor of the driving motor 21. The transmission unit 15 includes a positioning shaft 23, and a driven pulley 24 is fixedly connected to the outer end of the positioning shaft 23. The driving pulley 22 and the driven pulley 24 are driven by a synchronous belt 25. The transmission unit 15 also includes a gear 26 fixedly connected to the outer side of the positioning shaft 23, a longitudinal slide 27 fixedly connected to the mounting plate 13, and a rack 28 slidably connected in the longitudinal slide 27. The rack 28 is meshed with both sides of the gear 26 respectively, and a driving rod 29 is fixedly connected to the side of the rack 28 facing the inclined plate 19, and the driving rod 29 is against the outer surface of the inclined plate 19.

[0027] When the driving unit 14 does not cause the tilting plate 19 to move, the limit transverse rod 17 will be retracted into the inner side of the capstan under the spring force of the second spring 20, so that the resistance required by the anchor chain can be adjusted according to the demand. The driving motor 21 rotates to drive the driving pulley 22 to rotate, and then drives the driven pulley 24 to rotate. The driven pulley 24 drives the gear 26 to rotate, so that the rack 28 slides along the longitudinal groove 27. At this time, the driving rod 29 will move in reverse or towards each other at the same time. Since the driving rod 29 is against the surface of the tilting plate 19, the tilting plate 19 will move along the direction of the driving guide rod 18 during the movement, so as to make adjustments.

[0028] Working principle: The device is fixed on the hull. When in use, the drive shaft 3 drives the winch to realize the retraction and release of the anchor chain. The position of the winch can be locked by the manual locking mechanism 4. At the same time, the friction between the anchor chain and the winch can be adjusted by the auxiliary locking mechanism 5 to avoid slipping and avoid causing safety accidents. The position of the limiter 8 can be changed during the cooperation between the locking positioning member 9 and the limiter 8. When the locking positioning member 9 slides downward, due to the thick upper part, the limiter 8 will be lifted up and moved to the outside of the prism shaft 6. The limiter 8 will engage with the prism shaft 6 to prevent the prism shaft 6 from rotating. At this time, the anchor winch can be fixed. On the contrary, when the locking positioning member 9 moves upward, due to the thin lower part of the locking positioning member 9, the limiter 8 will be separated from the engagement state with the prism shaft 6 under the action of the spring force of the first spring 12, and the winch can rotate normally. Since the locking positioning member 9 moves downward to engage, the engagement state can be effectively and firmly ensured under the dual action of gravity and the spring force of the first spring 12. The driving unit 14 drives the transmission unit 15 to move, so that the tilting plate 19 moves along the direction of the driving guide rod 18, and the limit transverse rod 17 is further exposed from the side edge of the capstan, and the surface roughness is significantly increased, which greatly increases the friction between the anchor chain and the capstan, ensuring the safety of use. When the limit transverse rod 17 moves too much, it will be directly inserted into the anchor chain, which can more effectively avoid the slippage between the anchor chain and the capstan. When the driving unit 14 does not cause the tilting plate 19 to move, the limit transverse rod 17 will be retracted into the inner side of the capstan under the spring force of the second spring 20, so that the resistance required by the anchor chain can be adjusted according to demand. The driving motor 21 rotates to drive the driving pulley 22, which in turn drives the driven pulley 24 to rotate. The driven pulley 24 drives the gear 26 to rotate, so that the rack 28 slides along the longitudinal groove 27. At this time, the driving rod 29 will move in opposite directions or move towards each other at the same time. Since the driving rod 29 is against the surface of the inclined plate 19, the inclined plate 19 will move along the direction of the driving guide rod 18 during the movement, thereby making adjustments.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
