Example 2

As shown in fig. 3, an anchor for effecting expansion of a fluke by marine operations comprises an anchor rod 6, a fluke seat 10, a movable fluke 12, anchor lines 1 and an action line 2. The lower part of the anchor rod 6 has an external thread 8. The fluke socket 10 has a sleeve with an internal thread 10 therein. The anchor claw seat 10 is sleeved on the anchor rod 6 through threads. Fluke 12 is connected to fluke mount 10 via fluke shaft 11. The lower end of the anchor rod 6 is provided with a sear 16. The upper end of the sleeve of the anchor claw seat 10 is connected with two symmetrical support rods 7, the upper end of the two support rods is provided with a support rod top hole 27, and the anchor rod 6 passes through the hole with extremely small clearance. The support bar 7 has wire guides 5. The action rope 2 is connected with the anchor rod 6, and is led out from the wire guide hole 5 after being wound on the anchor rod 6 for a plurality of circles.

This solution sear 16 does not provide a jack function for the locked state.

Example 3

As shown in fig. 5, this is the labor saving type of embodiment 1. The anchor rod 6 is sleeved with a large-diameter reel 20, and the action rope 2 is connected with the reel 20, wound for a plurality of circles and led out through the wire guide hole 5 and the action rope guide hole 21. Otherwise, the same procedure as in example 1 was repeated.

Example 4

As shown in fig. 7 (locked state), an anchor for effecting expansion of fluke by marine operations comprises anchor rod 6, fluke seat 10, movable fluke 12, anchor line 1, action line 2 and safety line 22. The lower part of the anchor rod 6 has an external thread 8. The fluke socket 10 has a sleeve with an internal thread 10 therein. The anchor claw seat 10 is sleeved on the anchor rod 6 through threads. Fluke 12 is connected to fluke mount 10 via fluke shaft 11. The inner end of fluke 12 has a binding groove 19. The lower end of the anchor rod 6 is fitted with a bearing 15. The upper end of the sleeve of the anchor claw seat 10 is connected with two symmetrical support rods 7, the upper end of the two support rods is provided with a support rod top hole 27, and the anchor rod 6 passes through the hole with extremely small clearance. The top end of the anchor rod 6 is provided with an anchor rod top ring 4 and a connecting ring 3. The anchor line 1 is connected with a connecting ring 3. In order to drive the anchor rod 6 to rotate and unlock the lock more easily, a specially-made lengthened helical gear 24 is installed outside the anchor rod 6, and the helical gear 24 is fixedly connected with the anchor rod 6 and rotates synchronously. A worm 25 is arranged on the two support rods 7 connected with the fluke-holder sleeve, and the worm 25 is meshed with the helical gear 24. The worm 25 has an extended portion 26 extended outward long as a spool for winding the action cord 2 and the safety cord 22, and has an annular cord stopper 36 at its end. The action rope 2 and the safety rope 22 may be two ropes or two ends of one rope. The rope is wound on the outward extending section 26 of the worm for a plurality of turns and then is respectively led out upwards through the action rope guide hole 21 and the safety rope guide hole 23. Sufficient fastening friction can be obtained by winding several turns.

When unlocking, the action rope 2 is pulled, the worm 25 drives the helical gear 24 to rotate, and the anchor rod 6 is synchronously driven to rotate (clockwise rotation when viewed from top to bottom). At this time, since the external thread 8 of the lower section of the anchor rod 6 is engaged with the internal thread 9 of the fluke base 10, the fluke 12 is in a state of being caught in the river bed, the fluke base 10 cannot be rotated, and the anchor rod 6 inevitably moves downward. Because the helical gear 24 is specially lengthened, the anchor rod 6 cannot be disengaged from the worm 25 in the downward movement process, and can be continuously driven to rotate by the worm 25, and the bearing 15 serving as a locking iron block continuously descends until the bearing 15 loses the function of propping up the movable anchor claw 12. At this point the movable fluke 12 is opened without the jack of the bearing 15 at the back, so that the unlocked condition of figure 7 and figure 8 is achieved and the anchor can be lifted. In order to increase the safety of the anchorage, the actuation rope 2 and the safety rope 22 are preferably the two ends of one rope, i.e. the other end of the actuation rope 2 is used as the safety rope 22. After anchoring the substrate, the safety line 22 can be tensioned again in synchronism with tensioning of the anchor line 1, in case of unlocking by pulling the actuation line 2 by mistake. Of course, before the water is anchored, the anchor rod 6 can be driven to rotate anticlockwise by pulling the safety rope 22, so that the anchor enters the locking state from the unlocking state. Otherwise, the same procedure as in example 1 was repeated.

Example 5

As shown in fig. 9-12, the lower end of anchor rod 6 is fixedly connected to fluke mount 10, and fluke 12 is connected to fluke mount 10 via fluke shaft 11. The upper section of the anchor rod 6 is provided with an external thread 28, the periphery of the anchor rod is sleeved with a lengthened helical gear 24, the helical gear 24 is provided with an axial internal thread 30, and the helical gear 24 is in threaded connection with the anchor rod 6. The upper section of the anchor has a downwardly projecting worm support 35 for mounting the worm 25 to drive the bevel gear 24. The worm 25 has an extended portion 26 extended outward long as a spool for winding the action cord 2 and the safety cord 22, and has an annular cord stopper 36 at its end. A bearing inner ring 31 is fixedly connected to the lower section of the helical gear 24, and bearing balls 32 are provided between the bearing inner ring 31 and the bearing outer ring 37. The lower end of the bearing outer race ring 37 has a groove plate 38, and the groove plate 38 has a positioning groove 33. The moveable fluke 12 has projecting set teeth 34. The rest is the same as example 4.

Before anchoring, the safety rope 22 is pulled to rotate the worm 25 to drive the bevel gear 24 to rotate, because the bevel gear internal thread 30 is meshed with the anchor rod external thread 28, the bevel gear horizontally rotates and moves downwards, the combined motion drives the inner ring 31, the outer ring 37, the groove plate 38 and the positioning groove 33 to synchronously descend until the positioning groove 33 is sleeved on the positioning teeth 34 of the anchor fluke 12, the orientation of the movable anchor fluke 12 is fixed, and then the anchor can be anchored. When the anchor needs to be pulled, the action rope 2 is pulled, the worm 25 rotates to drive the bevel gear 24, the bevel gear horizontally rotates and moves upwards at the same time, the positioning groove 33 below the bevel gear is driven to move upwards, and the constraint on the positioning teeth 34 of the movable fluke 12 is lost. At the moment, the fluke 12 can be expanded by slightly pulling the anchor rope 1 to reach the unlocking state shown in figure 9, the ground holding force is lost, and the anchor is lifted. In this embodiment, the main function of the bearing balls 32 is to transmit pulling force, and to prevent the outer ring of the bearing from rotating horizontally when the positioning groove 33 rises during unlocking, thereby saving labor. The greatest difference between this embodiment and the other embodiments is that the anchor bar 6 does not rotate when unlocked. When the anchor device is stored after the anchor is lifted, the movable anchor fluke 12 can be folded upwards to reach the state shown in figure 11, the occupied space is reduced, and the portable anchor device is convenient to carry.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention, the technical solutions and the inventive concepts equivalent to or changed from the technical solutions and the inventive concepts within the scope of the present invention.
