Description

Technical Field

[0001] This invention relates to an anchor, specifically an anchor with movable anchor claws and an actuating rope.

[0002] Technical Background

[0003] When a ship needs to maintain a fixed position on the water, it generally uses anchorages. Existing anchorages typically consist of an anchor rope (chain) and an anchor. Apart from shore anchors, raising the anchor usually involves strong mechanical traction to forcibly lift it, in which case the angle between the anchor bolt and the anchor claws generally does not change. The drawback of this common anchorage method is that raising the anchor usually requires the ship to sail above the anchorage, and generally requires strong mechanical traction to lift the anchor. Summary of the Invention

[0004] The purpose of this invention is to change the angle between the movable anchor claw and the anchor rod by pulling a rope on the water surface. This allows the anchor claw to spread outwards, forming a large obtuse angle between the anchor rod and the anchor claw, causing the anchor claw to lose its grip and making it easier to lift the anchor, thus facilitating the raising of the ship's anchor. This is especially useful for small and medium-sized vessels without mechanical power for anchoring. The anchor is first deployed in a locked state and hooked onto the seabed. When raising the anchor, pulling the rope manually causes the anchor claw to open, allowing the ship to raise the anchor purely by manpower. It can also be used for outdoor climbing activities.

[0005] The technical solution of the present invention is as follows: an anchor that opens its claws through water operation, including an anchor rod, an anchor claw seat and an anchor claw. In addition to the conventional anchor rope, there is an additional actuating rope on the anchor. The anchor claw is connected to the anchor claw seat by a pivot. Pulling the actuating rope can drive the locking mechanism of the anchor, causing the anchor claw to be released from its locked state, the anchor claw to open, lose its grip, and the anchor rope and anchor can be retrieved.

[0006] Preferably, the locking mechanism includes a sleeve connected to the anchor claw seat and a support rod connected to the sleeve. The support rod is provided with a wire hole. The lower section of the anchor rod, the anchor claw seat, and the sleeve are connected by threads. Pulling the action rope drives the anchor rod to rotate, and at the same time, the anchor rod moves up and down relative to the anchor claw seat.

[0007] Preferably, the actuation rope is connected to the anchor rod and is wound around the anchor rod several times before being led out from the wire hole on the support rod. Pulling the actuation rope directly drives the anchor rod to rotate and move up and down relative to the anchor claw seat.

[0008] Preferably, the actuation rope drives the anchor rod to rotate via a worm-like mechanism. The worm-like mechanism is an elongated helical gear set on the anchor rod, and a worm is set on the support rod. The elongated helical gear meshes with the worm. When the actuation rope is pulled to drive the worm shaft to rotate, it drives the helical gear to rotate, and at the same time, it causes the helical gear to move up and down.

[0009] Preferably, a large-diameter winding wheel is fitted onto the anchor bolt, the action rope is connected to the large-diameter winding wheel, and after being wound several times, it is led out.

[0010] Preferably, the inner end of the anchor claw has a boss and a binding groove.

[0011] Preferably, the inner end of the anchor claw is a toothed disc, which engages with the external thread at the lower end of the anchor rod.

[0012] Preferably, the lower end of the anchor rod is provided with a stop iron, and the gap between the boss and the anchor rod is adapted to the bearing; preferably, the stop iron is a bearing.

[0013] Preferably, the locking mechanism includes a downwardly extending worm gear bracket on the anchor rod, with an anchor claw seat fixedly connected to the lower end of the anchor rod; the anchor rod has external threads, and an extended helical gear is fitted around the outer periphery of the anchor rod; the helical gear has an axial threaded hole and is threadedly connected to the anchor rod; a worm gear meshing with the helical gear is installed on the worm gear bracket, and the actuating rope drives the worm shaft to rotate, which in turn drives the helical gear to rotate and simultaneously causes the helical gear to move up and down; an anchor claw locking device is provided at the lower end of the helical gear.

[0014] Preferably, the anchor claw locking device includes an anchor claw positioning tooth extending upward from the inner end of the anchor claw, a bearing inner ring fixedly connected to the lower end of the helical gear, bearing balls between the bearing inner ring and the bearing outer ring; a groove plate at the lower end of the bearing outer ring, with a positioning groove on the groove plate; and the anchor claw positioning tooth and the positioning groove are adapted to each other.

[0015] Beneficial effects:

[0016] This invention simplifies anchoring, allowing for manual anchoring as long as the anchor weight doesn't exceed human capacity. In applications such as fisheries, water tourism, and outdoor fishing, small anchors can be manually thrown a considerable distance. Furthermore, by throwing three anchors in three directions, boats and rafts can be essentially fixed in place, preventing easy changes in orientation and resisting wind, waves, and currents. This is particularly suitable for situations requiring fixed work locations. Because the small anchors allow for manual release of the anchor claws, anchoring is possible manually, broadening the range of anchorage options and significantly expanding application scenarios. Currently, many small vessels in my country lack mechanical anchoring power units and can only anchor near the shore. However, using the anchors described in this invention allows for easier relocation across vast water surfaces, enabling fixed-point and directional operations in different locations. It also provides greater convenience for outdoor climbing activities. Attached Figure Description

[0030] Specific implementation methods

[0031] Example 1

[0032] like Figure 1 and Figure 6 As shown, an anchoring device that opens its claws via waterborne operation includes an anchor rod 6, an anchor claw seat 10, a movable anchor claw 12, an anchor rope 1, and an actuating rope 2. The lower part of the anchor rod 6 has an external thread 8. The anchor claw seat 10 has a sleeve with an internal thread 10 inside. The anchor claw seat 10 is threaded onto the anchor rod 6. The anchor claw 12 is connected to the anchor claw seat 10 via an anchor claw pivot 11. The inner end of the anchor claw 12 has a boss 29 and a binding groove 19. When the anchor claw 12 is opened and locked, the gap between the boss 29 and the anchor rod 6 is adapted to a bearing 15. A bearing 15 is installed at the lower end of the anchor rod 6. Two symmetrical support rods 7 are connected to the upper end of the sleeve of the anchor claw seat 10. A support rod top hole 27 is located where the upper ends of the two support rods meet, through which the anchor rod 6 passes with minimal clearance. The support rod 7 has a guide wire hole 5. The actuation rope 2 is connected to the anchor rod 6, and after being wound several times around the anchor rod 6, it is led out from the guide wire hole 5. The top of the anchor rod 6 has an anchor rod top ring 4 and a connecting ring 3. The anchor rope 1 is connected to the connecting ring 3.

[0033] Before anchoring, first twist the anchor rod 6 upwards. At this time, the actuating rope 2 will wrap around the upper part of the anchor rod 6 several times until the bearing 15 approaches the anchor claw seat 10, and the outer wall of the bearing outer ring 14 abuts against the anchor claw 12. The anchor claw 12 cannot open outwards. Use rubber bands, binding ropes, or non-closed elastic steel wire rings to secure it in the binding groove 19 to prevent the anchor claw from closing. At this time, the anchor can be thrown far away. After the anchor reaches the bottom, retrieve the anchor rope 1 to achieve anchoring. When the anchor is to be lifted, pull the actuating rope 2. At this time, the external thread 8 of the anchor rod interacts with the internal thread 10 of the anchor claw seat, and the anchor rod 6 moves downwards relative to the anchor claw seat 10. At this time, because the outer ring 14 of the bearing 15 does not rotate, the bearing 15 as a whole only needs a small force to move downwards until it can no longer contact the contact surface 13 between the anchor claw and the bearing. At this time, the anchor claw 12 opens outwards and approaches a straight line with the anchor rod 6. Figure 2 As shown, the anchor claw 12 loses its grip, and the anchor rope 1 is retracted to raise the anchor.

[0034] Example 2

[0035] like Figure 3As shown, an anchoring device that opens its claws via waterborne operations includes an anchor rod 6, an anchor claw seat 10, a movable anchor claw 12, an anchor rope 1, and an actuating rope 2. The lower part of the anchor rod 6 has an external thread 8. The anchor claw seat 10 has a sleeve with an internal thread 10 inside. The anchor claw seat 10 is threaded onto the anchor rod 6. The anchor claw 12 is connected to the anchor claw seat 10 via an anchor claw pivot 11. A stopper 16 is provided at the lower end of the anchor rod 6. Two symmetrical support rods 7 are connected to the upper end of the sleeve of the anchor claw seat 10. A support rod top hole 27 is located at the meeting point of the upper ends of the two support rods, through which the anchor rod 6 passes with minimal gap. The support rod 7 has a guide hole 5. The actuating rope 2 is connected to the anchor rod 6 and, after being wound several times around the anchor rod 6, is led out from the guide hole 5. The top of the anchor rod 6 has an anchor rod top ring 4 and a connecting ring 3. The anchor rope 1 is connected to the connecting ring 3. The inner end of the anchor claw 12 is a toothed disc 18, which has oblique teeth 17. The oblique teeth 17 engage with the external thread 8 at the lower end of the anchor rod 6.

[0036] Before anchoring, rotate the anchor bolt 6. The external thread 8 of the anchor bolt will drive the helical teeth 17 on the toothed disc 18 of the anchor claw 12 until the anchor claw 12 rotates to a suitable gripping angle, at which point anchoring can begin. When raising the anchor, pull the action rope 2. At this time, since the anchor claw 12 and the anchor claw seat 10 cannot rotate, the anchor bolt 6 will interact with the helical teeth 17 on the toothed disc 18, causing the angle between the anchor bolt 6 and the anchor claw 12 to tend towards an obtuse angle, just as... Figure 4 As shown, when the anchor claw 12 loses its grip, the anchor rope 1 can be easily retrieved to raise the anchor. In this design, the sear 16 does not provide support in the locked state.

[0037] Example 3

[0038] like Figure 5 As shown, this is the labor-saving version of Specific Embodiment 1. A large-diameter winding reel 20 is fitted onto the anchor rod 6. The actuating rope 2 is connected to the winding reel 20 and, after being wound several times, is led out through the wire hole 5 and the actuating rope guide hole 21. Everything else is the same as in Embodiment 1.

[0039] Example 4

[0040] like Figure 7As shown in the locked state, an anchoring device that opens its claws via waterborne operations includes an anchor rod 6, an anchor claw seat 10, a movable anchor claw 12, an anchor rope 1, an actuating rope 2, and a safety rope 22. The lower part of the anchor rod 6 has an external thread 8. The anchor claw seat 10 has a sleeve with an internal thread 10 inside. The anchor claw seat 10 is threaded onto the anchor rod 6. The anchor claw 12 is connected to the anchor claw seat 10 via an anchor claw pivot 11. The inner end of the anchor claw 12 has a binding groove 19. A bearing 15 is installed at the lower end of the anchor rod 6. Two symmetrical support rods 7 are connected to the upper end of the sleeve of the anchor claw seat 10. A support rod top hole 27 is located where the upper ends of the two support rods meet, through which the anchor rod 6 passes with minimal clearance. The top of the anchor rod 6 has an anchor rod top ring 4 and a connecting ring 3. The anchor rope 1 is connected to the connecting ring 3. To facilitate easier rotation of the anchor bolt 6 for unlocking, a specially designed extended helical gear 24 is installed on the outside of the anchor bolt 6. The helical gear 24 is fixedly connected to the anchor bolt 6, and the two rotate synchronously. A worm gear 25 is installed on the two support rods 7 connected to the anchor claw sleeve, and the worm gear 25 meshes with the helical gear 24. The worm gear 25 has an extended section 26 that extends outwards for a considerable length, serving as a winding shaft for winding the action rope 2 and safety rope 22. Its end has an annular rope-blocking plate 36. The action rope 2 and safety rope 22 can be two separate ropes or the two ends of a single rope. After being wound several times on the extended section 26 of the worm gear, the rope is led upwards through the action rope guide hole 21 and the safety rope guide hole 23, respectively. Several turns of winding provide sufficient tightening friction.

[0041] During unlocking, pulling the action rope 2 causes the worm gear 25 to drive the helical gear 24 to rotate, simultaneously driving the anchor rod 6 to rotate (clockwise when viewed from above). At this time, because the external thread 8 of the lower section of the anchor rod 6 is engaged with the internal thread 9 of the anchor claw seat 10, the anchor claw 12 is gripping the riverbed, and the anchor claw seat 10 cannot rotate, so the anchor rod 6 will inevitably move downwards. Because the helical gear 24 is specially lengthened, the anchor rod 6 will not disengage from the worm gear 25 during its downward movement and can continue to be driven to rotate by the worm gear 25. The bearing 15, acting as a locking stop, continues to descend until the bearing 15 loses its function of supporting the movable anchor claw 12. At this time, the movable anchor claw 12, without the support of the bearing 15 behind it, will open, thereby achieving... Figure 7 Figure 8 Once the anchor is in the unlocked state, it can be lifted. To increase the safety of this anchor, the actuating rope 2 and the safety rope 22 are preferably the two ends of the same rope, with the other end of the actuating rope 2 used as the safety rope 22. After anchoring to the seabed, tighten the anchor rope 1, and then simultaneously tighten the safety rope 22 to prevent accidental pulling of the actuating rope 2, which could lead to unlocking. Of course, before anchoring on the water, the anchor rod 6 can also be rotated counterclockwise by pulling the safety rope 22 to move the anchor from the unlocked state to the locked state. Other aspects are the same as in Embodiment 1.

[0042] Example 5

[0043] like Figures 9-12 As shown, the lower end of the anchor rod 6 is fixedly connected to the anchor claw seat 10, and the anchor claw 12 is connected to the anchor claw seat 10 through the anchor claw shaft 11. The upper section of the anchor rod 6 has an external thread 28, and an extended helical gear 24 is fitted around the outer periphery of the anchor rod. The helical gear 24 has an axial internal thread 30, and the helical gear 24 is threadedly connected to the anchor rod 6. The upper section of the anchor rod has a downwardly extending worm gear bracket 35 for mounting the worm gear 25 and driving the helical gear 24. The worm gear 25 has an extended section 26 that extends outward for a relatively long time, serving as a winding shaft for winding the action rope 2 and the safety rope 22. Its end has an annular rope-blocking plate 36. The lower section of the helical gear 24 is fixedly connected to a bearing inner ring 31, and there are bearing balls 32 between the bearing inner ring 31 and the bearing outer ring 37. The lower end of the bearing outer ring 37 has a groove plate 38, and the groove plate 38 has a positioning groove 33. The movable anchor claw 12 has an extended positioning tooth 34. Other aspects are the same as in embodiment 4.

[0044] Before anchoring, pulling the safety rope 22 rotates the worm gear 25, driving the helical gear 24 to rotate. Because the internal thread 30 of the helical gear meshes with the external thread 28 of the anchor rod, the helical gear rotates horizontally and moves downward simultaneously. This combined motion causes the inner ring 31, outer ring 37, groove plate 38, and positioning groove 33 to descend synchronously until the positioning groove 33 engages the positioning teeth 34 of the anchor claw 12, thus fixing the position of the movable anchor claw 12, allowing anchoring to proceed. When anchoring is required, pulling the action rope 2 rotates the worm gear 25, driving the helical gear 24. The helical gear rotates horizontally and moves upward simultaneously, causing the positioning groove 33 below it to move upward, losing its constraint on the positioning teeth 34 of the movable anchor claw 12. At this point, simply pulling the anchor rope 1 allows the anchor claw 12 to extend outward, achieving... Figure 9 In the unlocked state, the anchor loses its grip, allowing for anchoring. In this embodiment, the main function of the bearing balls 32 is to transmit pulling force, and simultaneously prevent the outer ring of the bearing from rotating horizontally when the positioning groove 33 rises during the unlocking process, thus saving effort. The biggest difference between this embodiment and other embodiments is that the anchor rod 6 does not rotate during unlocking. When storing the anchor after anchoring, the movable anchor claw 12 can be folded upwards to achieve… Figure 11 This design reduces the space it occupies and makes it easy to carry.

[0045] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the invention, should be covered within the scope of protection of the present invention.
