Description

Technical Field

[0001] The present invention relates to an anchor, in particular to an anchor with a movable anchor claw and an action rope. Technical Background

[0002] When ships need to secure their position on the water, they typically use anchors. Existing anchors typically consist of an anchor rope (chain) and an anchor. With the exception of shore anchors, anchoring is often done by mechanically pulling the anchor up, forcibly lifting it. The angle between the anchor rod and the fluke typically remains unchanged. The drawback of this common anchor system is that it typically requires the ship to sail over the anchor and requires a powerful mechanical traction device to lift the anchor. Summary of the Invention

[0003] The purpose of this invention is to change the angle between the movable fluke and the anchor rod by pulling a rope from the water surface, allowing the fluke to extend outward, forming a large obtuse angle between the anchor rod and fluke, and thus losing its grip on the ground, making it easier to lift the anchor and facilitate anchoring. This is particularly useful for small and medium-sized vessels that lack mechanical anchoring. The anchor is first cast in a locked state, allowing it to latch onto the bottom. During anchoring, the rope is then manually pulled to activate the fluke, allowing the vessel to be anchored manually. This device can also be used for outdoor climbing activities.

[0004] The technical solution of the present invention is: an anchor that can realize the opening of the anchor claw through water operation, including an anchor rod, an anchor claw seat and an anchor claw. In addition to the conventional anchor rope, the anchor claw is also provided with an action rope. The anchor claw is connected to the anchor claw seat with a rotating shaft. Pulling the action rope can drive the locking mechanism of the anchor claw, causing the anchor claw to be released from the locking state, the anchor claw to open, lose grip, reclaim the anchor rope, and retract the anchor claw.

[0005] Preferably, the locking mechanism includes a sleeve connected to the anchor claw seat, and a support rod connected to the sleeve, a wire hole is provided on the support rod, the lower section of the anchor rod and the anchor claw seat and the sleeve are connected by threads, and the pulling action rope drives the anchor rod to rotate, and at the same time makes the anchor rod move up and down relative to the anchor claw seat.

[0006] Preferably, the action rope is connected to the anchor rod and is wound around the anchor rod for several turns before being led out from the wire hole on the support rod. Pulling the action rope directly drives the anchor rod to rotate and move up and down relative to the fluke seat.

[0007] Preferably, the action rope drives the anchor rod to rotate through a worm-like mechanism. The worm-like mechanism is an extended helical gear provided on the anchor rod. A worm is provided on the support rod. The extended helical gear is engaged with the worm. When the action rope is pulled to drive the worm shaft to rotate, the helical gear is driven to rotate, and the helical gear is moved up and down at the same time.

[0008] Preferably, a large diameter winding wheel is mounted on the anchor rod, the action rope is connected to the large diameter winding wheel, and is wound several times before being led out.

[0009] Preferably, the inner end of the fluke has a boss and a binding groove.

[0010] Preferably, the inner end of the fluke is a toothed disc, which is engaged with the external thread at the lower end of the anchor rod.

[0011] Preferably, a sear is provided at the lower end of the anchor rod, and the gap between the boss and the anchor rod is adapted to a bearing; preferably, the sear is a bearing.

[0012] Preferably, the locking mechanism includes a downward-extending worm gear bracket provided on the anchor rod, and the anchor claw seat is fixedly connected to the lower end of the anchor rod; the anchor rod has an external thread, and an extended helical gear is mounted on 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 is mounted on the worm gear bracket that engages with the helical gear, and the action rope drives the worm shaft to rotate, and when the worm rotates, it drives the helical gear to rotate, and at the same time causes the helical gear to move up and down; an anchor claw locking device is provided at the lower end of the helical gear.

[0013] Preferably, the anchor claw locking device includes an anchor claw positioning tooth extending upward from the inner end of the anchor claw, the lower end of the bevel gear is fixedly connected to the inner ring of the bearing, and a bearing ball is provided between the inner ring of the bearing and the outer ring of the bearing; the lower end of the outer ring of the bearing is provided with a groove plate, and the groove plate has a positioning groove; the anchor claw positioning tooth is adapted to the positioning groove.

[0014] Beneficial effects:

[0015] The present invention makes it easier to raise the anchor. As long as the anchor weight does not exceed human capabilities, the anchor can generally be raised manually. When used in the fields of fishery production, water sightseeing, outdoor fishing, etc., if a small anchor is used, it can be thrown by hand to a longer distance. If three anchors can be further thrown in three directions, the boat or raft can be basically fixed, and the orientation will not change easily, resisting wind, waves and water currents. It is particularly suitable for situations where a fixed operating point is required. And because the small anchor can release the grip of the anchor claw manually and the anchor can be raised manually, the choice of anchorage is wider, which greatly expands the use scenario. At present, many small ships in my country can only be anchored on the shore because they do not have mechanical anchoring power devices. However, by using the anchor described in the present invention, it is possible to transfer more conveniently on a vast water surface and realize fixed-point directional operations at different locations. It can also provide more convenience for outdoor climbing activities. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Specific embodiment

[0030] Example 1

[0031] like Figure 1 and Figure 6 As shown, an anchor system for deploying the fluke by water operation includes an anchor rod 6, a fluke seat 10, a movable fluke 12, an anchor rope 1, and an action rope 2. The lower portion of the anchor rod 6 has an external thread 8. The fluke seat 10 has a sleeve with an internal thread 10. The fluke seat 10 is threadedly mounted on the anchor rod 6. The fluke 12 is connected to the fluke seat 10 via the fluke shaft 11. The inner end of the fluke 12 has a boss 29 and a binding groove 19. When the fluke 12 is deployed and locked, the gap between the boss 29 and the anchor rod 6 fits within the bearing 15. The lower end of the anchor rod 6 is mounted with a bearing 15. Two symmetrical support rods 7 are connected to the upper end of the sleeve of the fluke seat 10. A support rod top hole 27 is formed at the junction of the two support rods, through which the anchor rod 6 passes, with minimal clearance. The support rod 7 has a wire hole 5. The action rope 2 is connected to the anchor rod 6 and is wound around the anchor rod 6 for several turns before being led out from the wire hole 5. The top of the anchor rod 6 is provided with an anchor rod top ring 4 and a connecting ring 3. The anchor rope 1 is connected to the connecting ring 3.

[0032] Before dropping anchor, first twist the anchor rod 6 upwards. At this time, the action rope 2 will be wrapped around the upper part of the anchor rod 6 for several turns until the bearing 15 is close to the fluke seat 10. The outer wall of the bearing outer ring 14 is pressed against the fluke 12, and the fluke 12 cannot be opened outwards. Use a rubber band, a lashing rope or a non-closed elastic wire ring to clamp it in the lashing groove 19 to prevent the fluke from retracting. At this time, the anchor can be cast far away. After the anchor hits the bottom, the anchor rope 1 is retrieved to achieve anchoring. When it is time to heave the anchor, pull the action rope 2. At this time, the outer thread 8 of the anchor rod interacts with the inner thread 10 of the fluke seat, and the anchor rod 6 moves downward relative to the fluke seat 10. At this time, because the outer ring 14 of the bearing 15 does not rotate, the bearing 15 as a whole can move downward with only a small force until it can no longer contact the fluke and bearing contact surface 13. At this time, the fluke 12 is stretched outwards and approaches a straight line with the anchor rod 6. Figure 2 As shown, the fluke 12 loses its grip, the anchor rope 1 is retracted, and the anchor can be raised.

[0033] Example 2

[0034] like Figure 3As shown, an anchor system for deploying the flukes by water operation comprises an anchor rod 6, a fluke seat 10, a movable fluke 12, an anchor rope 1, and an action rope 2. The lower portion of the anchor rod 6 has an external thread 8. The fluke seat 10 has a sleeve with an internal thread 10 inside. The fluke seat 10 is threadedly mounted on the anchor rod 6. The fluke 12 is connected to the fluke seat 10 via a fluke shaft 11. A sear 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 fluke seat 10. A support rod top hole 27 is formed at the junction of the two support rods, through which the anchor rod 6 passes with minimal clearance. The support rod 7 has a wire hole 5. The action rope 2 is connected to the anchor rod 6 and, after being wound around the anchor rod 6 several times, is led out of the 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. The inner end of the fluke 12 is a toothed disc 18 having diagonal teeth 17. The diagonal teeth 17 engage with the external thread 8 at the lower end of the anchor rod 6.

[0035] Before dropping anchor, first rotate the anchor rod 6. The external thread 8 of the anchor rod will drive the oblique teeth 17 on the tooth plate 18 of the fluke 12 until the fluke 12 rotates to a suitable grip angle, and then the anchor can be dropped. When the anchor is raised, the action rope 2 is pulled. At this time, since the fluke 12 and the fluke seat 10 cannot rotate, the anchor rod 6 will interact with the oblique teeth 17 on the tooth plate 18, so that the angle between the anchor rod 6 and the fluke 12 tends to be obtuse, as shown in the following figure. Figure 4 As shown, the fluke 12 loses its grip and the anchor rope 1 is recovered, and the anchor can be easily raised. In this solution, the sear 16 does not provide a top support function for the locked state.

[0036] Example 3

[0037] like Figure 5 As shown, this is a labor-saving version of embodiment 1. A large-diameter winding wheel 20 is mounted on the anchor rod 6. The action rope 2 is connected to the winding wheel 20 and, after being wound several times, is drawn out through the wire hole 5 and the action rope guide hole 21. Other aspects are the same as those of embodiment 1.

[0038] Example 4

[0039] like Figure 7(Locked state) As shown, an anchoring device that can open the anchor claw by water operation includes an anchor rod 6, an anchor claw seat 10, a movable anchor claw 12, an anchor rope 1, an action 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 sleeve. The anchor claw seat 10 is screwed onto the anchor rod 6. The anchor claw 12 is connected to the anchor claw seat 10 through the anchor claw rotating shaft 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. There is a support rod top hole 27 at the junction of the upper ends of the two support rods. The anchor rod 6 passes through this hole with extremely small 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. In order to drive the anchor rod 6 to rotate and unlock it more effortlessly, a specially made extended bevel gear 24 is installed on the outside of the anchor rod 6. The bevel gear 24 is fixedly connected to the anchor rod 6, and the two rotate synchronously. A worm gear 25 is set on the two support rods 7 connected to the fluke seat sleeve, and the worm gear 25 meshes with the bevel gear 24. The worm gear 25 has an overhanging section 26 that extends outward longer and serves as a winding shaft for winding the action rope 2 and the safety rope 22. Its end has an annular rope retaining plate 36. The action rope 2 and the safety rope 22 can be two ropes or the two ends of a single rope. After being wound several times around the worm gear overhanging section 26, the rope is led upward through the action rope guide hole 21 and the safety rope guide hole 23 respectively. Winding several times can obtain sufficient tightening friction.

[0040] When unlocking, pull the action rope 2, the worm 25 drives the bevel gear 24 to rotate, and synchronously drives the anchor rod 6 to rotate (clockwise when viewed from top to bottom). At this time, since the external thread 8 of the lower section of the anchor rod 6 is in meshing state with the internal thread 9 of the anchor claw seat 10, the anchor claw 12 is in a state of grabbing into the riverbed, the anchor claw seat 10 cannot rotate, and the anchor rod 6 must move downward. Since the bevel gear 24 is specially made and lengthened, the anchor rod 6 will not be out of meshing state with the worm 25 during the downward movement, and can continue to be driven to rotate by the worm 25. The bearing 15 serving as the locking iron 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 will open because it no longer has the support of the bearing 15 at the back, thereby achieving Figure 7 Figure 8 The anchor can be lifted from the unlocked state. To increase the safety of the anchor, the action rope 2 and the safety rope 22 are preferably two ends of a single rope, with the other end of the action rope 2 serving as the safety rope 22. After anchoring the underwater substrate, the anchor rope 1 can be tightened, and then the safety rope 22 can be simultaneously tightened to prevent unlocking caused by accidentally pulling the action rope 2. Of course, before dropping anchor on the water, the anchor rod 6 can also be driven counterclockwise by pulling the safety rope 22, causing the anchor to enter the locked state from the unlocked state. Other aspects are the same as in Example 1.

[0041] Example 5

[0042] like Figures 9-12 As shown, the lower end of the anchor rod 6 is fixedly connected to the fluke seat 10, and the fluke 12 is connected to the fluke seat 10 via the fluke rotating shaft 11. The upper section of the anchor rod 6 has external threads 28, and an extended helical gear 24 is mounted on its outer circumference. The helical gear 24 has axial internal threads 30 and 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 25 and driving the helical gear 24. The worm 25 has an extended section 26 that extends outward and serves as a winding shaft for the action rope 2 and the safety rope 22. Its end is equipped with an annular rope retaining plate 36. The lower section of the helical gear 24 is fixedly connected to the inner bearing ring 31. A bearing ball 32 is positioned between the inner bearing ring 31 and the outer bearing ring 37. The lower end of the outer bearing ring 37 has a groove plate 38 with a positioning groove 33. The movable fluke 12 has a protruding positioning tooth 34. All other aspects are the same as those of Example 4.

[0043] Before dropping anchor, pull the safety rope 22 to rotate the worm 25 to drive the bevel gear 24 to rotate. Because the internal thread 30 of the bevel gear is engaged with the external thread 28 of the anchor rod, the bevel gear will move downward while rotating horizontally. This composite movement drives the inner ring 31, outer ring 37, groove plate 38 and positioning groove 33 to drop synchronously until the positioning groove 33 covers the positioning teeth 34 of the anchor claw 12. The position of the movable anchor claw 12 will be fixed, and then the anchor can be dropped. When it is necessary to raise the anchor, pull the action rope 2, the worm 25 will rotate, drive the bevel gear 24, and the bevel gear will move upward while rotating horizontally, driving the positioning groove 33 below it to move upward, and losing the constraint on the positioning teeth 34 of the movable anchor claw 12. At this time, you only need to pull the anchor rope 1 lightly, and the anchor claw 12 can be extended outward to achieve Figure 9 The main function of the bearing ball 32 in this embodiment is to transmit the pulling force. At the same time, during the unlocking process, it prevents the outer ring of the bearing from rotating horizontally when the positioning groove 33 rises, thereby saving effort. The biggest difference between this embodiment and other embodiments is that the anchor rod 6 does not rotate when unlocked. When storing the anchor after anchoring, the movable fluke 12 can be folded upwards to achieve Figure 11 state, reducing the space occupied and being easy to carry.

[0044] The above description is only a preferred specific embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent substitutions or changes based on the technical solution and inventive concept of the invention, which should be covered by the scope of protection of the present invention.
