[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4An anchor chain abandonment device for ships comprises: a mounting base 1; a rotating shaft 2 mounted on the lower end of the mounting base 1; a rotating shaft 2 on each side of the mounting base 1; and two connecting rotating plates 3, the first ends of which are respectively hinged to the two rotating shafts 2. The first ends of the connecting rotating plates 3 can rotate around the rotating shafts 2. When the connecting rotating plates are disconnected from the mounting base 1, the first ends of the connecting rotating plates 3 rotate and fall downwards, thereby releasing the anchor chain 7 connected to them at their lower ends. A connecting seat 4 is mounted between the second ends of the two connecting rotating plates 3; the anchor chain 7 of the ship is connected to the second end of the connecting seat 4; the first end of the connecting seat 4 is mounted between the second ends of the two connecting rotating plates 3, and the two connecting rotating plates 3 together limit the connection seat 4. When either connecting rotating plate 3 is disconnected from the mounting base 1, the connecting seat 4 is released, thereby releasing the anchor chain 7 connected to the connecting seat 4, achieving the purpose of abandoning the anchor chain.

[0025] The explosive bolt 5, installed on the mounting base 1, connects the rotating plate 3 to the mounting base 1 via the explosive bolt 5. This mechanism automatically disconnects the anchor chain from the vessel in emergencies, offering simple, safe, and reliable operation. The rotating plate 3 is mounted on the mounting base 1 via the explosive bolt 5. Upon detonation of the explosive bolt 5, the connection between the rotating plate 3 and the mounting base 1 is released. The rotating plate 3 then releases the connecting seat 4, thereby releasing the anchor chain 7 connected to the connecting seat 4, achieving the purpose of abandoning the chain.

[0026] The first end of the connecting seat 4 is provided with a connecting ball head 42, which is snapped between the second ends of the two connecting rotating plates 3. By using the ball head to snap between the second ends of the two connecting rotating plates 3, the connecting seat 4 can be released after either connecting rotating plate 3 is disconnected from the mounting seat 1, thereby releasing the anchor chain 7 connected to the connecting seat 4 and achieving the purpose of abandoning the chain.

[0027] A connecting pin 41 is provided on the second end of the connecting seat 4. The connecting pin 41 is connected to the anchor chain 7 and serves to connect with the anchor chain 7.

[0028] Each of the two connecting rotating plates 3 has a semi-circular groove at its second end, which can be adapted to the connecting ball head 42. The two semi-circular grooves form a complete circular groove, which facilitates the installation of the connecting ball head.

[0029] The mounting base 1 is also equipped with a protective base 6, which covers the explosive bolt 5 and serves to protect the explosive bolt 5.

[0030] The explosive bolt 5 is connected to the middle of the connecting rotating plate 3. When the explosive bolt 5 explodes, the connection between the connecting rotating plate 3 and the mounting base 1 is released. The connecting rotating plate 3 releases the connecting base 4, thereby releasing the anchor chain 7 connected to the connecting base 4, achieving the purpose of abandoning the chain.

[0031] With the above structure, the connection between the anchor chain and the ship can be automatically cut off in an emergency. The operation is simple, safe and reliable.
