Description

Technical Field

[0001] The utility model relates to the technical field of intelligent ships, in particular to an intelligent ship anchor chain length positioning device. Background Art

[0002] The anchor winch is an important deck equipment on the ship, mainly used for operations such as anchoring, anchoring, and mooring. It plays an important role in ensuring the safe operation of the ship. During the anchoring and anchoring process, the length of the anchor chain released is crucial to the safety of the ship. Therefore, the length of the anchor chain released needs to be measured when the anchor winch is working. In the existing anchor chain length measurement method, a common method is to install an encoder on the main shaft of the anchor winch to measure the length of the anchor chain released through the encoder. However, when the encoder error is large or even damaged and the numerical display is wrong, it is difficult for people to detect.

[0003] The reference patent name is: An intelligent ship anchor chain length positioning device (patent announcement number: CN218055525U patent publication date: 2022.12.16) includes: a driving mechanism, a winding mechanism, a positioning mechanism and a supporting mechanism. The driving mechanism includes a first coupling and a first connecting rod. The first connecting rod is installed on the right side of the first coupling, and the winding mechanism is installed on the right end of the first connecting rod. The winding mechanism also includes an anchor chain wheel, a rotating shaft and a second connecting rod. A rotating shaft is installed on the inner side of the anchor chain wheel, and a second connecting rod is installed on the right side of the rotating shaft. A positioning mechanism is installed on the right side of the second connecting rod. The positioning mechanism includes a third connecting rod, and a supporting mechanism is installed at the bottom of the third connecting rod. The utility model adopts an encoder and a meter to cooperate, which can accurately locate the length of the anchor chain. The double cooperation enables people to detect in time when the difference between the two values ​​is large, thereby ensuring the safe operation of the ship.

[0004] However, when implementing the above technical solutions, the following problems exist: 1. Although the length of the anchor chain can be accurately positioned, due to the heavy weight of the anchor chain itself, it may slide unexpectedly due to gravity or other external factors, resulting in inaccurate length positioning; 2. When releasing the ship's anchor chain, it is impossible to adjust the chain release speed and tension according to actual conditions. For this reason, the utility model provides an intelligent ship anchor chain length positioning device. Utility Model Content
