Description

TECHNICAL FIELD

[0002] Anchoring is to throw the anchor connected by anchor chain or anchor cable into water, and to fix the anchor on the bottom of the water by the anchor's grip. It is a common method for ships to stop. Figure 1 And Figure 2 As shown in the figures, when the ship is anchoring, the anchor chain 12 abuts against the support 110 on the ship body 100. Because the anchor chain 12 is close to the ship body 100, the ship body 100 and the anchor 13 will sway left and right in the wind and wave environment, which will cause the anchor 13 to collide with the ship body 100. The paint on the surface of the ship body 100 is easy to be scratched, which not only affects the appearance of the ship, but also damages the corrosion resistance of the ship body 100.

[0003] In order to avoid the collision between the anchor and the ship body, an anchor platform is usually extended on the outer plate of the ship body. When the ship is anchoring, the anchor chain or anchor cable abuts against the anchor platform, so that the anchor is far away from the ship body. Even if the ship body sways, the anchor will not collide with the ship body. However, the anchor platform occupies a large area and has a large weight, which is inconvenient to transport and install, and increases the construction cost and production cycle. SUMMARY

[0042] Embodiment one

[0043] Reference Figures 3 to 8The embodiment of the present application provides a ship anchoring device, which comprises an anchor assembly and a collision-preventing piece 20, the anchor assembly comprises an anchor windlass 11, an anchor chain 12 and an anchor body 13, the anchor windlass 11 is arranged on a ship body 100, the ship body 100 is provided with an anchor chain cylinder 101 and an anchor hole 102 communicated with the anchor chain cylinder 101, one end of the anchor chain 12 is connected with the anchor windlass 11, and the other end of the anchor chain 12 is connected with the anchor body 13; the collision-preventing piece 20 is rotationally arranged at the anchor hole 102, one end of the collision-preventing piece 20 is rotationally connected with the inner wall of the anchor hole 102, and the collision-preventing piece 20 can rotate between a deployed position and a storage position; in the deployed position, the other end of the collision-preventing piece 20 extends out of the anchor hole 102 and abuts against the anchor chain 12; and in the storage position, the collision-preventing piece 20 does not exceed the anchor hole 102.

[0044] When anchoring, the anchor windlass 11 drives the anchor chain 12 to move downwards along the anchor chain cylinder 101, the anchor body 13 moves downwards away from the anchor hole 102, and the collision-preventing piece 20 rotates from the storage position to the deployed position; in the process of rotating, the one end of the collision-preventing piece 20 extends out of the anchor hole 102 and abuts against the anchor chain 12; in the deployed position, the collision-preventing piece 20 supports the anchor chain 12 so that the horizontal distance between the anchor chain 12 and the ship body 100 is large, thereby avoiding the collision between the anchor body 13 and the ship body 100; when recovering the anchor, the anchor windlass 11 drives the anchor chain 12 to move upwards along the anchor chain cylinder 101, drives the anchor body 13 to move upwards, and drives the collision-preventing piece 20 to rotate from the deployed position to the storage position; when the collision-preventing piece 20 is in the storage position, the collision-preventing piece 20 does not exceed the anchor hole 102, and the anchor body 13 is recovered into the anchor hole 102, thereby reducing the space occupation; by arranging the collision-preventing piece 20, the collision-preventing piece 20 can rotate between the deployed position and the storage position, which can not only avoid the collision between the anchor body 13 and the ship body 100, but also save space, simplify the structure and reduce the cost.

[0045] The anchor windlass 11 is a prior art device, and the structure and working principle thereof will not be described herein.

[0046] The collision-preventing piece 20 is rotationally arranged at the anchor hole 102, which can rotate as a whole, or one part of the collision-preventing piece 20 can be fixed and the other part can rotate.

[0047] In the embodiment, the collision-preventing piece 20 comprises a plate body and a rotating shaft 22, the rotating shaft 22 is arranged at the end of the plate body, and the rotating shaft 22 is rotationally connected with the ship body 100. Specifically, the rotating shaft 22 is rotationally connected with the inner wall of the anchor hole 102, in the deployed position, the other end of the collision-preventing piece 20 extends out of the anchor hole 102, that is, the end away from the rotating shaft 22 extends out of the anchor hole 102. That is to say, the collision-preventing piece 20 can rotate between the deployed position and the storage position.

[0048] Optionally, the anti-collision member 20 is driven by a driving mechanism to rotate between the deployed position and the stowed position. The driving mechanism can include a hydraulic cylinder, a rack, and a gear. The piston rod of the hydraulic cylinder is connected with the rack, the rack is engaged with the gear, and the gear is connected with the rotating shaft 22. The hydraulic cylinder drives the rack to move linearly, and in turn drives the gear to rotate, and the gear drives the rotating shaft 22 to rotate. When anchoring, the hydraulic cylinder is started to drive the anti-collision member 20 to rotate from the stowed position to the deployed position. When de-anchoring, the hydraulic cylinder is started to drive the anti-collision member 20 to rotate from the deployed position to the stowed position.

[0049] In the embodiment, the anti-collision member 20 is driven by the anchor body 13 to rotate from the deployed position to the stowed position. In the stowed position, at least part of the anchor body 13 abuts against the outer side of the anti-collision member 20 to limit the anti-collision member 20. Specifically, when anchoring, the windlass 11 drives the anchor chain 12 to move downward along the anchor chain cylinder 101, the anchor body 13 moves downward away from the anchor hole 102, and the anti-collision member 20 rotates from the stowed position to the deployed position under the action of its own gravity. During the rotation of the anti-collision member 20, one end of the anti-collision member 20 extends out of the anchor hole 102 and abuts against the anchor chain 12. In the deployed position, the anti-collision member 20 supports the anchor chain 12 to make the horizontal distance between the anchor chain 12 and the ship body 100 greater than or equal to a first set value. When de-anchoring, the windlass 11 drives the anchor chain 12 to move upward along the anchor chain cylinder 101, and in turn drives the anchor body 13 to move upward. The anchor body 13 drives the anti-collision member 20 to rotate from the deployed position to the stowed position. When the anti-collision member 20 is in the stowed position, the anchor body 13 is recovered into the anchor hole 102, and part of the anchor body 13 abuts against the outer side of the anti-collision member 20 to limit the anti-collision member 20.

[0050] In the stowed position, the inner side of the anti-collision member 20 is in contact with the side wall of the anchor hole 102, thereby reducing the space occupation. When de-anchoring, the anchor body 13 drives the anti-collision member 20 to rotate from the deployed position to the stowed position, until the inner side of the anti-collision member 20 is in contact with the side wall of the anchor hole 102, and the anchor body 13 is recovered into the anchor hole 102. Specifically, the anchor hole 102 has an opening, and the inner side of the anti-collision member 20 is in contact with the side wall of the anchor hole 102 away from the opening.

[0051] In the stowed position, the included angle between the anti-collision member 20 and the horizontal plane is greater than or equal to 30 degrees and less than 90 degrees. On the one hand, this ensures that the anti-collision member 20 occupies a smaller space in the stowed position. On the other hand, this facilitates the movement of the anti-collision member 20 from the stowed position to the deployed position under the action of its own gravity.

[0052] Optionally, a torsional spring is arranged on the rotating shaft 22. When de-anchoring, the anchor body 13 drives the anti-collision member 20 to rotate from the deployed position to the stowed position, so that the torsional spring is compressed to store elastic potential energy. When anchoring, the anti-collision member 20 rotates from the stowed position to the deployed position under the elastic action of the torsional spring.

[0053] In the unfolded position, the anti-collision piece 20 extends horizontally, i.e. the anti-collision piece 20 is parallel to the horizontal plane. In other embodiments, the anti-collision piece 20 can also have an angle with the horizontal plane in the unfolded position, as long as it does not affect the abutment of the anti-collision piece 20 against the anchor chain 12, i.e. in the unfolded position, the anti-collision piece 20 abuts against the anchor chain 12, and the force of the anchor chain 12 against the anti-collision piece 20 makes the anti-collision piece 20 not easily displaceable.

[0054] Optionally, a support block 30 is arranged in the anchor hole 102, and in the unfolded position, the lower surface of the anti-collision piece 20 abuts against the support block 30. The support block 30 provides support for the anti-collision piece 20, so that the anti-collision piece 20 stably supports the anchor chain 12 in the unfolded position. In this embodiment, the top surface of the support block 30 is a horizontal plane, and in the unfolded position, the lower surface of the anti-collision piece 20 abuts against the top surface of the support block 30, increasing the contact area and ensuring that the anti-collision piece 20 extends horizontally.

[0055] One end of the anti-collision piece 20 is connected to the anchor hole 102, and the other end of the anti-collision piece 20 can extend out of the anchor hole 102 and abut against the anchor chain 12. The end of the anti-collision piece 20 is provided with a limiting groove 21, and in the unfolded position, the anchor chain 12 is located in the limiting groove 21. The limiting groove 21 limits the anchor chain 12, so that the anchor chain 12 can remain in the state of abutting against the anti-collision piece 20, ensuring the stability of the anchor chain 12.

[0056] In some embodiments, a wear-resistant layer is arranged on the inner wall of the limiting groove 21 to prevent the anchor chain 12 from wearing the anti-collision piece 20. In some embodiments, a roller is arranged on the inner wall of the limiting groove 21, and the anchor chain 12 abuts against the roller to reduce friction, so that the anchor chain 12 smoothly slides along the limiting groove 21.

[0057] Specifically, the limiting groove 21 is arranged at the end of the anti-collision piece 20 away from the rotating shaft 22. In this embodiment, the anti-collision piece 20 is plate-shaped, which is simple in structure and easy to install. Referring to Figure 7 and Figure 8 , the limiting groove 21 is arranged on the limiting end surface of the anti-collision piece 20. The limiting groove 21 can be arranged at the middle position of the limiting end surface, or the limiting groove 21 can be gradually deepened from both ends of the limiting end surface to the middle.

[0058] When the anchor is thrown, the anti-collision piece 20 rotates from the storage position to the unfolded position. During the rotation of the anti-collision piece 20, the limiting end surface of the anti-collision piece 20 abuts against the anchor chain 12. Since the limiting groove 21 is gradually deepened from both ends of the limiting end surface to the middle, the anchor chain 12 abutting against any position of the limiting groove 21 can slide to the middle of the limiting groove 21.

[0059] In some embodiments, the anti-collision piece 20 is itself a telescopic piece, and the length of the anti-collision piece 20 can be adjusted according to requirements, so that the distance between the anchor body 13 and the ship body 100 can be adjusted to adapt to different types of ship bodies 100. It can be that the anti-collision piece 20 comprises a support plate and a telescopic plate, the inside of the support plate is hollow to form a cavity, at least part of the telescopic plate is located in the cavity and is driven by a hydraulic cylinder to adjust the length of the telescopic plate extending out of the cavity, and the telescopic plate can abut against the anchor chain 12.

[0060] The anti-collision piece 20 can be a stainless steel plate, and its specific size can be set according to actual needs.

[0061] Embodiment Two

[0062] Figure 9 And Figure 10 Embodiment Two is shown, in which the same or corresponding parts as in Embodiment One are denoted by the same reference numerals as in Embodiment One. For the sake of simplicity, only the differences between Embodiment Two and Embodiment One are described. The difference is that, in the deployed position, the anti-collision piece 20 extends obliquely downward, and the lower end of the anti-collision piece 20 abuts against the anchor chain 12, and the anti-collision piece 20 has a tendency to rotate downward under the action of the anchor chain 12. By arranging the anti-collision piece 20 to extend obliquely downward, the anchor chain 12 is facilitated to abut against the anti-collision piece 20 to press the anti-collision piece 20 tightly.

[0063] Specifically, in the deployed position, the anti-collision piece 20 abuts against the inner wall of the anchor hole 102, and the anchor hole 102 functions as a limit for the anti-collision piece 20.

[0064] Embodiment Three

[0065] The present embodiment provides a ship anchoring method, which uses the ship anchoring device described above, and comprises the following steps:

[0066] When anchoring, the anchor windlass 11 drives the anchor chain 12 to move downward along the anchor chain cylinder 101, the anchor body 13 moves downward away from the anchor hole 102, and the anti-collision piece 20 rotates from the stowed position to the deployed position. During the rotation of the anti-collision piece 20, one end of the anti-collision piece 20 extends out of the anchor hole 102 and abuts against the anchor chain 12. In the deployed position, the anti-collision piece 20 supports the anchor chain 12 so that the horizontal distance between the anchor chain 12 and the ship body 100 is greater than or equal to a first set value.

[0067] When anchoring, the anchor windlass 11 drives the anchor chain 12 to move upward along the anchor chain cylinder 101, driving the anchor body 13 to move upward, and the anti-collision piece 20 rotates from the deployed position to the stowed position. When the anti-collision piece 20 is in the stowed position, the anti-collision piece 20 does not exceed the anchor hole 102, and the anchor body 13 is recovered into the anchor hole 102.

[0068] In the case that the anti-collision piece 20 is rotationally connected with the anchor hole 102 and the anchor body 13 pushes the anti-collision piece 20 to rotate from the storage position to the unfolded position, in the storage position, part of the anchor body 13 abuts against the outer side of the anti-collision piece 20 to limit the anti-collision piece 20. When anchoring, the anchor windlass 11 drives the anchor chain 12 to move downward along the anchor chain cylinder 101, the anchor body 13 moves downward away from the anchor hole 102, the anchor body 13 is separated from the anti-collision piece 20, and the anti-collision piece 20 rotates from the storage position to the unfolded position under the action of its own gravity. In the process of rotating the anti-collision piece 20, one end of the anti-collision piece 20 extends out of the anchor hole 102 and abuts against the anchor chain 12. In the unfolded position, the anti-collision piece 20 supports the anchor chain 12 so that the horizontal distance between the anchor chain 12 and the ship body 100 is greater than or equal to the first set value. When anchoring, the anchor windlass 11 drives the anchor chain 12 to move upward along the anchor chain cylinder 101, and drives the anchor body 13 to move upward. When the anchor body 13 moves to abut against the anti-collision piece 20, the anchor body 13 pushes the anti-collision piece 20 to rotate from the unfolded position to the storage position, until the anti-collision piece 20 abuts against the side wall of the anchor hole 102, the anti-collision piece 20 is located in the storage position, the anchor body 13 is recovered into the anchor hole 102, and part of the anchor body 13 abuts against the outer side of the anti-collision piece 20 to limit the anti-collision piece 20.

[0069] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments. Without departing from the spirit and scope of the present application, the present application can have various changes and modifications, and these changes and modifications all fall within the scope of the present application.
