[0002] Anchors are an important part of ships, mainly used to fix the position of ships to prevent them from drifting with the waves or being washed away by wind and currents. There are many types of anchors, the most common ones are grab anchors, steel anchors, shackle anchors, etc. The material of anchors is usually cast iron or steel, which needs to have high strength and wear resistance. Low-loss and anti-fracture anchors are because during long-term use, the anchors will be subjected to continuous tension and are prone to fatigue damage.

[0033] Specifically, when the anchor claw 12 is stuck on the seabed and cannot be retracted normally, the steel wire 3 is first pulled. One end of the steel wire 3 is connected to the sliding rod 2. When the steel wire 3 is pulled, the sliding rod 2 will be driven to move. The movement of the sliding rod 2 will also cause the sliding shaft 4 to slide on the inner wall of the spiral coil 5, thereby causing the spiral coil 5 to rotate, thereby driving the screw 6 to rotate on the inner wall of the main anchor rod 1. Then, the rotation of the screw 6 drives the sliding sleeve 7 to move. The movement of the sliding sleeve 7 will further drive the fixed blocks 8 on both sides to move. The fixed blocks 8 are connected to one end of the connecting rod 9. The movement of the fixed blocks 8 will drive one end of the connecting rod 9 to move. At this time, the other end of the connecting rod 9 will pull the rotating sleeve 10 to rotate, further driving the anchor claw 12 to rotate, so that the two anchor claws 12 will gradually approach each other, thereby reducing the angle between them. When the angle is small enough, the anchor claw 12 can be pulled out of the mud and sand on the seabed, and then the anchor can be pulled out smoothly.
[0034] Reference Figure 1 The connection assembly includes a fixing ring 22, the inner wall of the fixing ring 22 is fixedly connected to the outer wall of the main anchor rod 1, and the outer wall of the fixing ring 22 is fixedly connected to a lifting ring 23;
[0035] Specifically, the connection between the lifting ring 23 and the external anchor chain facilitates the use of the anchor.
[0036] Reference Figure 1 , Figure 4 and Figure 5 The outer wall of the anchor plate 11 is slidably connected with a fluke 12, the inner wall of the fluke 12 is slidably connected with a lower connecting ring 13, the outer wall of the lower connecting ring 13 is slidably connected to the inner wall of the rotating sleeve 10, the inner wall of the fluke 12 is slidably connected with an upper connecting ring 14, the outer wall of the upper connecting ring 14 is slidably connected to the inner wall of the lower connecting ring 13, the inner thread of the upper connecting ring 14 is connected with a threaded rod 16, one end of the threaded rod 16 is fixedly connected with a handle 15, the other end of the threaded rod 16 is fixedly connected with a slider 17, the outer wall of the slider 17 is slidably connected to the inner wall of the rotating sleeve 10, Connected to the inner wall of the upper connecting ring 14, the inner wall of the upper connecting ring 14 is slidably connected with a clamping block 18, the outer wall of the clamping block 18 is slidably connected to the upper connecting ring 14, the lower connecting ring 13 and the interior of the rotating sleeve 10, the outer wall of the clamping block 18 is fixedly connected with a telescopic rod 19, the outer wall of the telescopic rod 19 is sleeved with a spring 20, both ends of the spring 20 are fixedly connected to the outer wall of the clamping block 18, the outer walls of the lower connecting ring 13 and the upper connecting ring 14 are fixedly connected with a limiting block 21, and the outer wall of the limiting block 21 is slidably connected to the inner wall of the fluke 12;
[0037] Specifically, firstly, the rotation of the anchor claw 12 is limited by the limit block 21 to effectively fix the anchor claw 12. When the anchor claw 12 needs to be installed or removed, the handle 15 is driven to drive the threaded rod 16 connected thereto to rotate, and further drive the slider 17 to move. The movement of the slider 17 will exert a certain pressure on the block 18, so that the block 18 slides inside the upper connecting ring 14, the lower connecting ring 13 and the rotating sleeve 10. By accurately controlling the moving distance of the slider 17, it can be ensured that the block 18 can be accurately inserted into the predetermined position, thereby realizing the installation of the anchor claw 12. When removing, it is only necessary to rotate the handle 15 in the opposite direction, and the slider 17 will move in the opposite direction. At the same time, the spring 20 will also play its elastic role to help pull the block 18 back to the original position, so that the anchor claw 12 can be easily removed.
[0038] Working principle: When a low-loss anti-fracture anchor is needed, first, when the anchor claw 12 is stuck, pull the steel wire 3 to drive the slide rod 2 to move, and at the same time make the slide shaft 4 slide on the inner wall of the spiral ring 5, so that the spiral ring 5 rotates, and at the same time drives the screw 6 to rotate on the inner wall of the main anchor rod 1, and then pulls the sliding sleeve 7 to move, and then drives the fixed blocks 8 on both sides to move through the movement of the sliding sleeve 7, thereby driving one end of the connecting rod 9 to move, and then pulls the rotating sleeve 10 through the other end of the connecting rod 9 to rotate, driving the anchor claw 12 to rotate, so that the two anchor claws 12 gradually approach each other, and then The anchor is pulled out to facilitate recovery and placement of broken and unrecoverable anchors, and the anchor claw 12 is then limited by the limit block 21 to prevent it from moving at will. The threaded rod 16 is then driven to rotate by the handle 15 to move the slider 17 to apply pressure to the block 18, so that the block 18 slides inside the upper connecting ring 14, the lower connecting ring 13 and the rotating sleeve 10 to achieve installation. When disassembling, it is only necessary to reversely rotate the handle 15 and cooperate with the spring 20 to pull back the block 18 to disassemble the anchor claw 12, thereby achieving the effect of convenient disassembly and assembly.
