Description
Technical Field
[0001] The invention relates to the technical field of ship anchors, in particular to a foldable ship anchor. Background Art
[0002] Anchors are iron boat-stopping devices, mainly used to fix and stabilize ships. When used for temporary mooring, the anchor sinks to the bottom of the water, and under the action of inertia and gravity, it embeds into the mud, sand and stone geology at the bottom of the water, giving a strong pulling force to the rope connected to the anchor, so that the hull floats within a certain range, unaffected by water flow and wind flow, and the ship is firmly fixed in the reserved position. Anchors are indispensable safety equipment for ships, which can ensure safety and avoid turning around. There are many types of modern anchors, mainly including rod anchors, rodless anchors, high-grip anchors and special anchors.
[0003] Common ship anchors have fishhook-shaped, anchor claw-shaped, and gun-shaped structural designs. The ship anchor is a fixed structure and cannot be folded, so the ship anchor is inconvenient to store and transport. When collecting the anchor, the ship anchor is easily stuck by hard objects on the bottom of the water, which is not conducive to the smooth progress of the anchor collection operation.

[0024] Among them, the first clamping cap 5 is located on one side of the four groups of anchor claws 2, and its function is to clamp and limit one side of the four groups of anchor claws 2. The second clamping cap 7 is located on the other side of the four groups of anchor claws 2, and its function is to clamp and limit the other side of the four groups of anchor claws 2. When the first locking nut 6 is loosened, the first clamping cap 5 can slide along the axial direction of the first screw 3. When the second locking nut 8 is loosened, the second clamping cap 7 can slide along the axial direction of the second screw 4.
[0025] The folded state of the anchor is as follows Figure 5 and Figure 6 As shown, when using the anchor, the first locking nut 6 is loosened and the position of the first clamping cap 5 is adjusted, the second locking nut 8 is loosened and the position of the second clamping cap 7 is adjusted, and the external force applied to the four groups of flukes 2 by the first clamping cap 5 and the second clamping cap 7 is released. At this time, the four groups of flukes 2 can all rotate relative to the base 1, as shown in FIG. Figure 1 and Figure 2 As shown, the four groups of anchor claws 2 are deflected and opened at a certain angle. After the four groups of anchor claws 2 are opened, the position of the first clamping cap 5 is adjusted, the first clamping cap 5 is tightly attached to one side of the four groups of anchor claws 2, and then the first locking nut 6 is tightened to limit the first clamping cap 5. One side of the four groups of anchor claws 2 is limited by the first clamping cap 5.
[0026] Similarly, after the four groups of anchor claws 2 are opened, the position of the second clamping cap 7 is adjusted, and the second clamping cap 7 is tightly attached to the other side of the four groups of anchor claws 2. Then the second locking nut 8 is tightened to limit the second clamping cap 7. The other side of the four groups of anchor claws 2 is limited by the second clamping cap 7, and the two sides of the four groups of anchor claws 2 are limited by the first clamping cap 5 and the second clamping cap 7 respectively, so as to fix the four groups of anchor claws 2. At this time, the four groups of anchor claws 2 are in a fixed state and cannot be deflected relative to the base body 1, that is, the opening angle of the four groups of anchor claws 2 is limited by the first clamping cap 5 and the second clamping cap 7, and the opening angle of the four groups of anchor claws 2 is adjusted by adjusting the position of the first clamping cap 5 on the first screw 3 and the position of the second clamping cap 7 on the second screw 4.
[0027] When the anchor is not in use, the anchor is folded. When folding, the first locking nut 6 and the second locking nut 8 are loosened, the positions of the first clamping cap 5 and the second clamping cap 7 are adjusted, the limit of the four groups of anchor claws 2 is released, and the four groups of anchor claws 2 are folded. The folded state is as follows: Figure 5 As shown, after folding, the position of the first clamping cap 5 is adjusted so that the inner side surface of the first clamping cap 5 is in close contact with one end of the four groups of anchor claws 2, the four groups of anchor claws 2 are clamped, and then the first locking nut 6 is tightened to fix them. At this time, the four groups of anchor claws 2 are clamped and limited by the first clamping cap 5 and cannot be deflected relative to the base 1. They are in a stable folded state, which is conducive to storage and transportation.
[0028] In some examples, a first through hole 51 is opened in the center of the first clamping cap 5, and four groups of first clamping columns 52 are welded and fixed on the end surface of the first clamping cap 5 close to the base 1. The four groups of first clamping columns 52 are evenly distributed along the circumferential direction of the first clamping cap 5, and the four groups of first clamping columns 52 correspond to the four groups of anchor claws 2 one by one, and the four groups of first clamping columns 52 are used to limit the four groups of anchor claws 2.
[0029] Among them, when one side of the four groups of anchor claws 2 is tightened by the first clamping cap 5, the first locking nut 6 is first loosened, and then the position of the first clamping cap 5 is adjusted. The four groups of first clamping columns 52 of the first clamping cap 5 correspond to the four groups of anchor claws 2 respectively, and the four groups of first clamping columns 52 are tightly attached to one side of the four groups of anchor claws 2. After the adjustment is completed, the first locking nut 6 is tightened to limit the first clamping cap 5, and the four groups of anchor claws 2 are respectively clamped and limited by the four groups of first clamping columns 52 of the first clamping cap 5.
[0030] In some examples, the first screw rod 3 passes through the first through hole 51 of the first pressing cap 5 , and the first locking nut 6 is threadedly connected to the first screw rod 3 .
[0031] Among them, the position of the first locking nut 6 on the first screw 3 is adjustable. By adjusting the position of the first locking nut 6, the first clamping cap 5 can be tightened and loosened. When the first clamping cap 5 is tightened, the position of the first clamping cap 5 is fixed and cannot be moved. When the first clamping cap 5 is loosened, the first clamping cap 5 can move along the axial direction of the first screw 3.
[0032] In some examples, a second through hole 71 is opened in the center of the second clamping cap 7, and four groups of second clamping columns 72 are welded and fixed on the end surface of the second clamping cap 7 close to the base 1. The four groups of second clamping columns 72 are evenly spaced along the circumferential direction of the second clamping cap 7. The four groups of second clamping columns 72 correspond to the four groups of anchor claws 2 one by one, and the four groups of anchor claws 2 are limited by the four groups of second clamping columns 72.
[0033] Among them, when the other side of the four groups of anchor claws 2 are compressed by the second clamping cap 7, the second locking nut 8 is loosened first, and then the position of the second clamping cap 7 is adjusted. The four groups of second clamping columns 72 of the second clamping cap 7 correspond to the four groups of anchor claws 2 respectively, and the four groups of second clamping columns 72 are tightly attached to the other side of the four groups of anchor claws 2. After the adjustment is completed, the second locking nut 8 is tightened to limit the second clamping cap 7, and the four groups of anchor claws 2 are compressed and limited by the four groups of second clamping columns 72 of the second clamping cap 7.
[0034] In some examples, the second screw rod 4 passes through the second through hole 71 of the second pressing cap 7 , and the second locking nut 8 is threadedly connected to the second screw rod 4 .
[0035] Among them, the position of the second locking nut 8 on the second screw 4 is adjustable. By adjusting the position of the second locking nut 8, the second clamping cap 7 can be tightened and loosened. When the second clamping cap 7 is tightened, the position of the second clamping cap 7 is fixed and cannot be moved. When the second clamping cap 7 is loosened, the second clamping cap 7 can move along the axial direction of the second screw 4.
[0036] By adopting the above technical solution: The four groups of anchor claws 2 are all rotatable relative to the base body 1, and the deflection angles of the four groups of anchor claws 2 are all adjustable. When in use, the deflection angles of the four groups of anchor claws 2 are adjusted, and the two sides of the four groups of anchor claws 2 are limited and fixed by the first clamping cap 5 and the second clamping cap 7 respectively, so that the four groups of anchor claws 2 are kept fixed at a certain opening angle, and the anchor is opened and put into use. When not in use, the first locking nut 6 and the second locking nut 8 are loosened to release the limit of the four groups of anchor claws 2, and the four groups of anchor claws 2 are folded. After folding, the position of the first clamping cap 5 is adjusted so that the inner side surface of the first clamping cap 5 is tightly attached to one end of the four groups of anchor claws 2, the four groups of anchor claws 2 are compressed, and then the first locking nut 6 is tightened to fix the anchor, so that the anchor is in a stable folded state, which is convenient for storage and transportation.
[0037] The opening angles of the four groups of flukes 2 can be flexibly adjusted by adjusting the position of the first clamping cap 5 on the first screw rod 3 and the position of the second clamping cap 7 on the second screw rod 4 .
[0038] Embodiment 2: Based on Example 1, this example introduces a specific structure of the first connector 31 and the second connector 41 in a foldable anchor, such as Figure 1 and Figure 2 As shown, a first rope threading hole 32 is provided on the first connector 31 , and the first anchor rope 9 passes through the first rope threading hole 32 of the first connector 31 and is fixedly connected to the first connector 31 in a knotted manner.
[0039] In some examples, a second rope threading hole 42 is formed on the second connector 41 , and the second anchor rope 10 passes through the second rope threading hole 42 of the second connector 41 and is fixedly connected to the second connector 41 by a knot.
[0040] Among them, the first anchor rope 9 is the main anchor rope, and the second anchor rope 10 is the auxiliary anchor rope, both of which can be used to drop and retrieve the anchor. When retrieving the anchor, the anchor machine is started to tighten the first anchor rope 9. One end of the first anchor rope 9 is connected to the ship. When the anchor rope is tightened, the ship will move toward the direction of the anchor and gradually approach the anchor. When the angle between the ship and the first anchor rope 9 is close to vertical, the anchor will be pulled up to realize the recovery of the anchor.
[0041] When the fluke 2 of the ship anchor is stuck by a hard object and cannot be pulled out, an external force is applied to the second anchor rope 10 to retrieve the anchor from the end of the second anchor rope 10, thereby pulling out the ship anchor, which is helpful for the anchor retrieval operation.
[0042] Embodiment 3: Based on Example 1 and Example 2, this embodiment introduces a specific structure of the anchor claw 2 in a foldable anchor, a groove 211 is provided on the hook 21, a notch 212 is provided on the side of the hook 21, a connecting hole 213 is provided at the connecting end of the hook 21, the connecting shaft 12 of the base 1 passes through the connecting hole 213 of the hook 21, and the hook 21 and the connecting shaft 12 are rotatably connected.
[0043] Among them, the anchor claw 2 is mainly composed of two parts, namely the hook claw 21 and the auxiliary claw 22. When the anchor is thrown into the water, its own gravity will make it sink to the bottom of the water quickly. After touching the bottom, the anchor will be embedded in the mud and sand and stone geology at the bottom of the water under the action of inertia and gravity. The four groups of anchor claws 2 with claw-like structure ensure that they can firmly grasp the bottom geology after the anchor sinks to the bottom to prevent the hull from continuing to move.
[0044] The hook claw 21 is a claw-like structure, and the auxiliary claw 22 is a claw-like structure with a barb 221. When dropping anchor, the hook claw 21 and the barb 221 of the auxiliary claw 22 can both contact with the bottom geology, thereby improving the gripping effect of the anchor claw 2.
[0045] In some examples, a barb portion 221 is disposed on the auxiliary claw 22 , and the barb portion 221 and the auxiliary claw 22 are an integrally formed structure, and the auxiliary claw 22 is embedded in the groove 211 of the hook claw 21 .
[0046] In some examples, a third screw 222 is fixedly disposed on the auxiliary claw 22 , and the third screw 222 passes through the notch 212 of the hook claw 21 . The hook claw 21 and the auxiliary claw 22 are fixedly connected via a third locking nut 223 .
[0047] Among them, the position of the auxiliary claw 22 relative to the hook claw 21 is adjustable. When the third locking nut 223 is loosened, the auxiliary claw 22 can move in the groove 211 of the hook claw 21. At this time, the position of the auxiliary claw 22 can be adjusted. After the position adjustment of the auxiliary claw 22 is completed, the third locking nut 223 is re-tightened. When the anchor is in use, the auxiliary claw 22 can be extended for use. When the anchor is not in use, the auxiliary claw 22 is completely embedded in the groove 211 of the hook claw 21 and fixed. On the one hand, the auxiliary claw 22 is protected, and on the other hand, the barb 221 is prevented from causing damage, thereby improving safety.
[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
