DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] The utility model provides a detachable anchor.
[0021] like Figure 1-2As shown, it includes an anchor rod 1 and an anchor chain 2 connected to the upper end of the anchor rod 1. A fixing ring is fixed to the lower end of the anchor rod 1. Four hinge pieces extend outward from the outer wall of the fixing ring. A number of anchor claws 3 are hinged on the hinge pieces. A positioning ring 4 is fixed to the lower end of the anchor rod 1. A positioning cover 5 is rotationally and slidably connected to the anchor rod 1. A reset opening 6 is provided at the upper end of the positioning cover 5. A limiting strip is provided at the lower end of the anchor rod 1. The positioning cover 5 is slidably connected to the limiting strip. The outer edge of the positioning cover 5 abuts against the inner side of the anchor claw 3. A sliding spring 7 is connected between the positioning ring 4 and the positioning cover 5. A resisting convex block 8 is integrally formed at the hinged end of the anchor claw 3. The resisting convex block 8 abuts and is clamped at the lower end of the anchor rod 1. The positioning cover 5 abuts against the upper inner wall of the anchor claw 3 to position the upper side of the anchor claw 3, and can abut and clamp the anchor claw 3 to prevent the anchor claw 3 from contracting inward during seabed fixation, resulting in a reduction in the grasping force. The resisting convex block 8 abuts and is clamped at the lower end of the anchor rod 1 to position the lower side of the anchor claw 3 and limit the angle of outward rotation of the anchor claw 3, preventing the anchor claw 3 from over-rotating after grasping the ground and causing the anchor claw 3 to flip and fail to grasp the ground.
[0022] A transmission sleeve 9 is rotatably connected to the middle of the anchor rod 1. A support block 10 is provided on the outer wall of the transmission sleeve 9. The support block 10 abuts against the upper end of the positioning cover 5. The support block 10 of the transmission sleeve 9 abuts against the positioning cover 5 to position the positioning cover 5, so that the positioning cover 5 is fixedly abutted against the anchor claw 3. When unlocking is required, rotate the transmission sleeve 9. When the support block 10 on the transmission sleeve 9 rotates to a position aligned with the reset opening 6, the positioning cover 5 can be pushed upward by the sliding spring 7, so that the positioning cover 5 is separated from the anchor claw 3, realizing the unlocking of the anchor claw 3.
[0023] Above the anchor rod 1, an unlocking sleeve 11 is sleeved. The lower end of the unlocking sleeve 11 extends with a limiting rod 12. A sliding hole is formed on the outer wall of the transmission sleeve 9. The limiting rod 12 is slidably inserted into the sliding hole. The limiting rod 12 is clamped on the sliding hole on the outer wall of the transmission sleeve 9. An arc-shaped slot hole 13 is formed on the unlocking sleeve 11. An unlocking protrusion 16 that slidably cooperates with the arc-shaped slot hole 13 is arranged at the upper end of the outer wall of the anchor rod 1. A load-bearing cross beam 14 is arranged at the upper end of the unlocking sleeve 11. The upper end of the anchor chain 2 is sleeved with a pressure ring 15 that can slide on the anchor chain 2 and strike on the load-bearing cross beam 14. The pressure ring 15 slides downward along the anchor chain 2 from top to bottom and abuts on the load-bearing cross beam 14 under its own gravity. Under pressure, the load-bearing cross beam 14 and the unlocking sleeve 11 slide downward. During the sliding process, the unlocking protrusion 16 plays a guiding role for the arc-shaped slot hole 13, so that the unlocking sleeve 11 rotates during the downward sliding process. The limiting rod 12 at the lower end of the rotating unlocking sleeve 11 drives the transmission sleeve 9 to rotate, and then the support block 10 can be rotated to align with the reset opening 6. In addition, under the action of the self-gravity of the pressure ring 15, the ship anchor will be offset and tilted, and the grasping force with the seabed ground becomes smaller. At the same time, the pressure ring 15 is stuck on the load-bearing cross beam 14, which is convenient for the collection of the pressure ring 15.
[0024] A limiting plate 17 is arranged on the outer wall of the positioning cover 5. The support block 10 abuts and is clamped on the limiting plate 17. The limiting plate 17 plays a limiting role and limits the rotation position of the transmission sleeve 9, so as to avoid unlocking caused by the transmission sleeve 9 rotating too much and the support block 10 coinciding with the reset opening 6 when the anchor claw 3 is in the open state.
[0025] A threaded rod is integrally formed at the lower end of the anchor rod 1. A support nut 18 is threadedly connected to the threaded rod. A positioning round table 19 is arranged at the upper end of the support nut 18. The abutting convex block 8 abuts on the outer side wall of the positioning round table 19. The end of the threaded rod is a conical head. Rotating the support nut 18 can finely adjust the positioning round table 19 up and down at the lower end of the anchor rod 1. After the positioning cover 5 abuts and clamps the anchor claw 3, the inclined surface of the positioning round table 19 is used to adjust and clamp the abutting convex block 8 that abuts on the anchor claw 3 at the lower end.
[0026] Working principle:
[0027] In the present utility model, during the process of dropping the anchor, the positioning cover 5 is slid so that the positioning cover 5 abuts on the anchor claw 3. The transmission sleeve 9 is rotated. The support block 10 on the outer side of the transmission sleeve 9 abuts on the positioning cover 5 to form a lock. Then the support nut 18 is rotated. The inclined surface of the positioning round table 19 abuts on the abutting convex block 8 of the anchor claw 3, so that the anchor claw 3 can be kept in the open state.
[0028] When the anchor needs to be lifted, lower the pressure ring 15. The pressure ring 15 slides downward along the anchor chain 2 and impacts and presses on the load-bearing cross beam 14. The load-bearing cross beam 14 slides downward. Under the interaction of the arc-shaped slot hole 13 and the unlocking protrusion 16, the unlocking sleeve 11 rotates and slides downward. The limit rod 12 slides in the sliding hole and drives the transmission sleeve 9 to rotate circumferentially at the same time. When the support block 10 is aligned with the reset opening 6, under the support of the sliding spring 7, the positioning cover 5 slides upward to disengage from the anchor claw 3 to unlock the anchor claw 3, so that the anchor claw 3 can contract inward. At the same time, under the impact of the pressure ring 15, the whole anchor slides downward on the seabed. The anchor claw 3 will contract inward, reducing the force-bearing area and facilitating the lifting of the anchor.
[0029] At the same time, the gravity of the pressure ring 15 will cause the whole anchor to tilt. During the tilting process, the anchor claw 3 is in the unlocked state, and the anchor claw 3 can contract inward, without playing a supporting role to cause the situation where the anchor cannot tilt, which is convenient for lifting the anchor.
[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
