Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0033] Example 1

[0034] A 4-type triangular anchor with a chute, such as Figure 1 As shown, it comprises an anchor rod 1 and an anchor head 2. The anchor rod 1 is provided with a slide groove 4 which is matched with an anchor chain shackle 3. The slide groove 4 is arranged at the upper end of the anchor rod 1.

[0035] When the present embodiment is in use, when the triangular anchor enters the sea, the weight of the anchor head 2 is greater than the weight of the anchor rod 1. When dropping anchor, the anchor head 2 is downward, and the anchor chain shackle 3 is located at the end of the anchor rod 1 away from the anchor head 2, so that the anchor head 2 falls to the bottom of the water to achieve a fixing effect. When it is necessary to raise the anchor, if the resistance to raising the anchor is large, the pulling force used for raising the anchor is large, and forcible raising the anchor will cause serious damage to the windlass. At this time, the anchor chain can be pulled to make the anchor chain shackle 3 move in the chute 4 toward the direction of the anchor head 2, thereby changing the raising center of gravity of the triangular anchor, so that a large part of the raising force can be saved, and the raising work can be completed quickly.

[0036] It can be understood that in order to expand the scope of use, the slide groove 4 extends from one end of the anchor rod 1 close to the anchor head 2 to the other end of the anchor rod 1 away from the anchor head 2.

[0037] Understandable, such as Figure 4 As shown, in order to prevent the anchor chain from being entangled on the anchor rod 1 when moving, in this embodiment, a baffle 5 for cooperating with the anchor chain shackle 3 is provided at the end of the anchor rod 1 away from the anchor head 2, and the baffle 5 is arranged at the lower end of the anchor rod 1. The baffle 5 is arranged in cooperation with the slide groove 4, so that the anchor chain can be ensured to be always located above the anchor rod 1.

[0038] Example 2

[0039] Based on Example 1, this embodiment further improves the structure of the chute 4-type triangular anchor, such as Figure 2-Figure 3As shown, in this embodiment, the anchor rod 1 includes a first connecting rod 11, a second connecting rod 12 and a third connecting rod 13 connected in sequence, the end of the first connecting rod 11 away from the second connecting rod 12 is connected to the anchor head 2, and the slide groove 4 extends from the end of the second connecting rod 12 close to the first connecting rod 11 to the end of the third connecting rod 13 away from the second connecting rod 12.

[0040] The slide groove 4 includes a first slide groove 41 arranged on the second connecting rod 12, and the slide groove 4 also includes a second slide groove 42 arranged on the third connecting rod 13. The central axis of the first slide groove 41 is arranged parallel to the central axis of the first connecting rod 11, and the central axis of the second slide groove 42 is arranged parallel to the central axis of the second connecting rod 12. The first slide groove 41 is connected to the second slide groove 42, and the connection between the first slide groove 41 and the second slide groove 42 is chamfered.

[0041] The anchor head 2 includes a first wing 21 and a second wing 22 connected to each other, the first wing 21 and the second wing 22 are connected to form a triangular anchor head 2, and the first connecting rod 11 is arranged on a connecting ridge 23 connecting the first wing 21 and the second wing 22. When the bottom end of the anchor head 2 is placed horizontally, the angle between the connecting ridge 23 and the horizontal line is 30-40°. The angle between the axis of the first connecting rod 11 and the connecting ridge 23 is 80-90°. The second connecting rod 12 is arranged horizontally upward at one end away from the first connecting rod 11, the angle between the axis of the second connecting rod 12 and the axis of the first connecting rod 11 is 120-130°, and the length of the second connecting rod 12 is 1.5-2 times the length of the second connecting rod 12. The third connecting rod 13 is arranged horizontally downward at one end away from the second connecting rod 12, the angle between the axis of the second connecting rod 12 and the axis of the third connecting rod 13 is 145-160°, and the length of the third connecting rod 13 is 2-3 times the length of the second connecting rod 12.

[0042] When the slide groove type triangular anchor in this embodiment is in use, since the end of the third connecting rod 13 away from the second connecting rod 12 is tilted downward, such a structure makes it possible for the anchor to be lifted, because the anchor head 2 is on the seabed and the anchor lifter is above the sea level. In order to ensure that the anchor chain shackle 3 moves in the direction of the anchor head 2 when moving in the slide groove 4, the end of the third connecting rod 13 away from the second connecting rod 12 is tilted downward to ensure that when the anchor head 2 is pulled upward during the anchoring process, the anchor chain shackle 3 can move more smoothly in the slide groove 4 toward the anchor head 2.

[0043] In this embodiment, the length of the third connecting rod 13 and the angle with the second connecting rod 12 are set so that when the anchor chain shackle 3 reaches the connection between the second connecting rod 12 and the third connecting rod 13, Figure 2As shown, in most cases, the anchor head 2 can successfully complete the anchoring work, so there is no need to move the anchor chain shackle 3 from one end of the anchor chain to the other end every time the anchor is lifted. This arrangement is to save energy and speed up the anchoring speed.

[0044] When the embodiment is in use, when it is necessary to raise the anchor, the anchor chain is pulled upwards, and the anchor chain shackle 3 is subjected to the upward pulling force and moves upwards along the slide groove 4, changing the center of gravity of the anchoring while raising the anchor. When the anchor head 2 is pulled up, due to its heavy weight, the anchor chain shackle 3 will move again to the end of the anchor rod 1 away from the anchor head 2, completing the anchoring work; when the anchor chain shackle 3 quickly moves to the connection between the second connecting rod 12 and the third connecting rod 13, as shown in FIG. Figure 2 As shown in FIG. 1 , the anchor cannot be lifted smoothly, indicating that the anchor head 2 may be stuck by stones or seaweed. At this time, the pulling direction of the anchor chain is changed so that the anchor chain shackle 3 continues to move toward the direction of the anchor head 2. Figure 3 As shown, the anchoring work is completed.

[0045] It can be understood that the length and angle settings of the several connecting rods in this embodiment are comprehensively considered from the perspective of anchoring efficiency and energy saving. Experiments have proved that the force used for anchoring using the slide groove 4-type triangular anchor in this application saves 30-40% of the force used for anchoring using the common triangular anchor (without the slide groove 4) on the market.

[0046] It can be understood that the material used for the slide-type triangular anchor in this embodiment is 316 type stainless steel, which has extremely high corrosion resistance to seawater.

[0047] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0048] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
