DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The anchor chain retracting and releasing device for ships comprises a base 1;

[0022] like Figures 1 to 3 As shown, a winding machine 2 is installed on the top of the base 1, and a rotating shaft 3 is rotatably connected to the top of the base 1. A guide wheel 4 is fixedly connected to the outside of the rotating shaft 3. Grooves 41 are equidistantly provided on the outside of the guide wheel 4. An annular groove 42 is also provided on the outside of the guide wheel 4. The centers of the grooves 41 are connected to the annular groove 42. Ratchets 5 are fixedly connected to the outsides of both ends of the rotating shaft 3. A support seat 6 is fixedly connected to the top of the base 1 on one side of the ratchet 5. A pawl 7 adapted to the corresponding ratchet 5 is rotatably connected to the inside of the support seat 6.

[0023] The groove 41 and the annular groove 42 can perfectly fit the shape of the anchor chain. During the process of pulling and winding the anchor chain, the horizontal chain link can be embedded in the groove 41, and the vertical chain link can be embedded in the annular groove 42, ensuring that the anchor chain can maintain a stable winding state when guided by the guide wheel 4, avoiding jamming or confusion caused by irregular chain link shapes.

[0024] like Figures 1 to 3 As shown, a push rod motor 8 is installed on the top of the support base 6, and the output end of the push rod motor 8 is connected to a traction block 9. The bottom end of the traction block 9 is rotatably connected to a connecting frame 10. The two sides of the bottom of the connecting frame 10 are rotatably connected to the two sides of the corresponding pawl 7 through connecting rods 11 respectively;

[0025] The push rod motor 8 can control the engagement state of the pawl 7 and the ratchet 5 through the transmission chain composed of the traction block 9, the connecting frame 10 and the connecting rod 11. When one ratchet 5 is engaged with the corresponding pawl 7, the other ratchet 5 is in a disengaged state from the corresponding pawl 7, ensuring that the rotating shaft 3 can only rotate in one direction, so that the guide wheel 4 can adapt to the needs of winding or releasing the anchor chain.

[0026] like Figures 1 to 3 As shown, the connecting frame 10 is covered with a torsion spring 12, and the connecting rod 11 is elastically connected to the corresponding connecting frame 10 through the torsion spring 12. The addition of the torsion spring 12 forms an elastic connection between the connecting rod 11 and the connecting frame 10. The elastic action of the torsion spring 12 can also help the pawl 7 to quickly return to its original position when subjected to external force, thereby ensuring the reliable operation of the pawl 7.

[0027] like Figures 1 to 3 As shown, the ratchet teeth of the ratchet wheels 5 at both ends of the rotating shaft 3 are arranged in opposite directions, which means that they can only rotate in one direction respectively.

[0028] like Figures 1 to 3 As shown, the middle part of the guide wheel 4 is in the shape of an octagonal prism, which increases the contact area and friction between the guide wheel 4 and the anchor chain, thereby improving the stability and reliability of the anchor chain on the guide wheel 4. The octagonal prism design can also disperse the pressure of the anchor chain on the guide wheel 4 to a certain extent, thereby extending the service life of the guide wheel 4.

[0029] like Figures 1 to 3 As shown, the winder 2 includes a motor drive device 21 and a drum 22. The motor drive device 21 is connected to the drum 22 through a transmission mechanism. When the anchor chain needs to be wound up, the motor drive device 21 is started to drive the drum 22 to rotate clockwise, thereby pulling the anchor chain from the guide wheel 4 and winding it onto the drum 22. On the contrary, when the anchor chain needs to be released, the motor drive device 21 is started in the reverse direction to drive the drum 22 to rotate counterclockwise, thereby releasing the anchor chain from the drum 22 and letting it fall into the sea under the guidance of the guide wheel 4.

[0030] like Figures 1 to 3 As shown, the ratchet wheels 5 at both ends of the rotating shaft 3 are fixedly connected to the rotating shaft 3 through bearings, which improves the stability and reliability of the rotation of the ratchet wheel 5, reduces friction and wear, and extends the service life of the ratchet wheel 5. At the same time, the addition of bearings can also make the ratchet wheel 5 more flexible and stable during rotation.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
