Description

[Detailed description of the invention] The present invention relates to an anchor storage device, and its purpose is to
To provide an item which can easily and reliably store an anchor after lifting the anchor and is easy to design and produce.

An anchor usually has an anchor rod and an anchor claw, and when viewed from the side, both are inclined at a certain angle to each other.

When such an anchor is stored in the hull, the anchor is in a so-called external claw state in which the anchor claw faces outward with respect to the hull outer plate.

However, storing the anchor in the external claw state using the conventional anchor storage device causes various problems such as the weight of the anchor claw causing the anchor to rotate around the anchor rod, or the necessity of turning the anchor while lifting the anchor. There was a problem.

The present invention has been devised in view of the above, and an embodiment thereof will be described below based on FIGS. 1 and 2.

1 is a purge which is an example of a hull, and 2 is an inclined outer plate below the draft.

3 is a recess formed in the outer panel 2, and this recess 3 has a lower wall 4 perpendicular to the virtual horizontal plane and an upper wall opposite to this lower wall 4 and perpendicular to the outer panel 2. 5.

An anchor receiving portion 6 is formed between the lower wall 4 and the upper wall 5 within the recess 3.

The anchor receiver 6 has a trapezoidal shape with an inverted truncated roof, and its opposing inclined side surfaces 7 are flat.

The truncated surface 8 of the anchor receiving portion 6 is parallel to the outer plate 2.

The widening side edges of the opposite inclined side surfaces 7 are connected to the lower wall 4.
and are abutted against the inner edge of the upper wall 5, respectively.

Thus, anchor accommodation spaces 9A and 9B are formed in the recess 3 at the portions facing each inclined side surface 7.

An anchor rod storage hole 10 is formed in the anchor receiving portion 6 and is perpendicular to the truncated surface 8 thereof.

A ring-shaped bell mouth 11 is formed around the opening of the anchor rod storage hole 10.

This bell mouth 11 has an arcuate cross-sectional outer periphery, a portion of which slightly protrudes into the opening of the anchor rod storage hole 10, and another portion of which slightly protrudes onto the inclined side surface 7.

Note that an anchor chain hole 12 is communicated with the anchor rod storage hole 10.

Next, 13 is an anchor. The anchor 13 has an anchor rod 14 and anchor claws 15 on both sides of the anchor rod 14, both of which are inclined to each other by an angle substantially equal to the cone angle of the anchor receiving portion 6 in side view.

The anchor rod 14 is connected to a hoisting and feeding device (not shown) on the deck 16.

) is connected to an anchor chain 17 fed out through an anchor chain hole 12.

The operation of this configuration will be explained next.

When the anchor chain 17 is wound up and the anchor is lifted, the anchor rod 14 rises while contacting a point A on the inner peripheral surface of the bell mouth 11, and is about to be stored in the anchor rod storage hole 10.

Then, as the anchor 13 is continued to be pulled up, the anchor claw 15 is next pulled up.
Both tips of the anchor contact portion 6 contact two points E on the inclined side surface 7 of the anchor receiving portion 6.

At this stage, the contact points between the anchor receiving part 6 and the anchor 13 are three points A,
D? It is E.

Then, when the anchor 13 is pulled up further, both bases of the anchor claw 15 also come into contact with two points B and C on the outer peripheral surface of the bell mouth 11.

As a result, the anchor receiving portion 6 and the anchor 13 are in contact with each other at five points A to E.

Note that these operations and contact points have been confirmed through experiments.

Next, when the contact points between the anchor receiver 6 and the anchor 13 are five points A to E, the anchor chain 17 is fixed by applying a predetermined tension.

In this case, even if the anchor rotates during anchor lifting, the anchor rod 14 is pulled into its storage hole 10 and breaks, and subsequent lifting after the point when the anchor claw 15 contacts the anchor receiving part 6 occurs. By the anchor,
Rotation is prevented by the inclined side surface 7 of the anchor receiving portion 6 of the anchor 13II'i, and the anchor 13II'i is placed in the inner claw state shown in the figure or in the outer claw state displaced by 180 degrees from this state.

In the retracted state, the anchor 13 is substantially entirely housed within the quadrant 3.

In this state, the anchor rod 14 and the base of the anchor claw 15 are in contact with the bell mouth 11 at a total of three points A, B, and C, and the anchor claw 1
The tip of 5 contacts the inclined side surface 7 at two points in total at E.

Therefore, there are a total of five contact points A between the anchor 13 and the anchor receiving part 6.
,B.

C, D, and E, resulting in a stable and reliable storage state.

Although not shown, if the anchor 13 is retracted in the external claw state, the inclined side surface 7 with which the anchor claw 15 engages is a flat surface, so the weight of the anchor claw 15 prevents the anchor 13 from rotating. It won't happen.

As is clear from the above description, according to the present invention, the anchor receiving part is configured as a trapezoid with an inverted truncated roof shape, and its opposing sloped sides are flat, so that the anchor claw is an outer claw and an inner claw. In either of these conditions, rotation of the anchor is reliably prevented by engagement between the anchor claw and the inclined side surface.

Therefore, even if the tension on the anchor chain is loosened due to unforeseen circumstances,
Not only would it be impossible for the anchor to rotate and lock itself, but there is also a bell mouth with an arc-shaped cross-sectional outer periphery that protrudes into the opening and onto the sloping side surface of the anchor receiver. Since there are five points of contact between the anchor receiver and the anchor, stable and reliable storage is possible.

In addition, since there are no curved parts, design, manufacturing, board cutting, and on-site installation work becomes easier.

Additionally, since there is no need to perform a turning operation when lifting anchor, there is no need for model experiments.

Since the enclosed anchor receiving part is formed within the recess of the hull outer plate, it can be designed and manufactured without being influenced by the complex curved shape of the hull.
