As one of the most important systems of a ship: the anchoring system plays an irreplaceable role in the safety of the ship. However, the application of intelligent technology to mooring systems is not very optimistic, mainly because the manual functions of several of the main devices, one of the most important of which is not replaced by automatic functions: this is especially true of the chain stopper. The chain stopper is a device for clamping an anchor chain when a ship sails or is anchored, and the bearing capacity of the chain stopper needs to be more than 80% of the breaking load of the anchor chain, so that the structure of the chain stopper is very heavy. The most common of these is a guillotine chain stopper, which is designed to stop the anchor chain mainly by the blade jamming in a vertical loop passing through a guide channel, which is very simple in construction. The main operation mode is that the knife switch is manually lifted or pressed down, the bolt is inserted or pulled out by one person on the other side to ensure safety, and meanwhile, the real-time position of the anchor chain is adjusted by one person operating the anchor machine so that the knife switch is lifted up and pressed down. Through the analysis, 3-4 persons are needed to complete the simple one-step operation cooperatively. . For intelligent unmanned anchor operation, it is desirable to develop a powered controllable chain stopper device that can be operated remotely or programmatically.

Detailed Description
For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.
As shown in fig. 1, an automatic chain stopper, including base 1 and chain stopper mechanism, the base top surface is the inclined plane, chain stopper mechanism is fixed in the base top, chain stopper mechanism includes drive assembly, U type support 2, left slider 3 and right slider 4, U type support bottom is equipped with spout 5, left and right slider moves along the spout, drive assembly includes motor 6, derailleur and two-way screw 7, two-way screw passes the screw of left and right slider, both ends are fixed in the support both sides through the bearing, the motor passes through the derailleur and links to each other with the one end of two-way screw, it is rotatory to drive two-way screw. The two ends of the bidirectional screw are threads with identical parameters but opposite directions, so that the left and right sliding blocks can move in opposite directions under the drive of the same screw.
The corresponding end surfaces of the left and right sliding blocks are respectively provided with a chain pulling groove 8 which is matched with the anchor chain ring. And the end surfaces of the left and right sliding blocks at the same side are symmetrically provided with a left stop lever and a right stop lever. When the left and right sliding blocks are closed, the distance between the left and right stop rods is less than the width of the anchor chain ring, so that the stop function is realized.
The device also comprises a guide rod 9, the guide rod passes through the guide holes of the left and right sliding blocks, and two ends of the guide rod are fixed on two sides of the support. The cooperating runner ensures a linear movement of the slide and takes up part of the tension from the anchor chain 10 to the slide.
The centers of the bottoms of the left and right sliding blocks are provided with convex blocks which are matched with the sliding grooves.
The two-way screw rods are arranged in an up-and-down symmetrical mode.
When the device is adopted to carry out chain pulling, the method comprises the following steps:
as shown in fig. 2, when the anchor machine is used for taking out the anchor, the anchor chain is completely recovered by the anchor machine, the anchor is properly attached to the main hull, the motor is started to rotate in the forward direction, the rotating speed and the torque of the motor are reduced and amplified by the transmission and then transmitted to the bidirectional screw rod, the left and right sliding blocks are driven by the bidirectional screw rod to simultaneously move towards the middle until the left and right sliding blocks simultaneously clamp the horizontal anchor chain ring of the anchor chain, and the blocking rods on the left and right sliding blocks are blocked at the front end of the horizontal anchor chain ring, so that the anchor chain cannot shake or slide downwards.
As shown in fig. 3, when the anchoring operation is to be performed, the starting motor rotates in the reverse direction, drives the left and right slide blocks to slide to the two sides, releases the clamped anchor chain, and conveys the anchor chain into water by the anchor machine or gravity. And when the length of the dropped anchor chain reaches the specified requirement, repeating the action described in the previous section, and tightly clamping the anchor chain again. At the moment, the acting force on the anchor chain is larger when the ship is influenced by the flow velocity, and the left sliding block and the right sliding block bear very large tangential force. The sliding block distributes the tangential force to the guide rod and the sliding groove for bearing.
