Description

An anchor cavity structure for a deltaic anchor Technical Field

[0001] This invention belongs to the field of anchoring equipment, and specifically relates to a Deltai anchor cavity structure. Background Technology

[0002] An anchor is a key component of anchoring equipment, used to securely anchor ships, platforms, and other floating structures at sea to a predetermined position. When not in use, anchors need to be stored and secured to prevent damage due to rough seas or improper handling. Currently, the main methods for storing and securing anchors are anchorage storage and anchor frame storage.

[0003] There are various types of anchors, one of which is the Deltai anchor 02. The Deltai anchor 02 is a high-holding-force anchor. The structure of the Deltai anchor 02 is shown in Figures 1 and 2. It includes an anchor rod 021 and an anchor claw 022 hinged to the bottom of the anchor rod 021. The anchor angle (i.e., the angle between the axis of the anchor claw 022 and the axis of the anchor rod 021) is approximately 35°. The anchor claw 022 has an isosceles triangular structure, and the gap between the two claw tips is very small. If the existing anchor cavity is used to house the Deltai anchor 02, the claw tip at the top of the anchor claw 022 can easily enter the anchor chain cylinder 03, causing the anchor chain cylinder 03 to be squeezed and deformed. In addition, even if the claw tip of the anchor claw 022 does not enter the anchor chain cylinder 03, the claw tip is relatively sharp and can easily pierce the top plate of the anchor cavity. Therefore, based on the special structure of Deltai Anchor 02, major manufacturers and technicians mainly designed and used anchor frames to store and fix Deltai Anchor 02, while neglecting the research on the anchor hole of Deltai Anchor 02, which resulted in a large gap in the design of the anchor hole of Deltai Anchor 02. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a simple anchor cavity structure for Deltai anchors, which is used to house Deltai anchors, prevent the anchors from partially entering the anchor chain tube during storage, causing deformation and damage to the anchor chain tube, and improve the service life of the anchor chain tube.

[0005] To achieve the above and other related objectives, the present invention provides an anchor cavity structure for a Deltai anchor, comprising an anchor cavity disposed on a floating structure, the anchor cavity being used to accommodate the anchor claw of the Deltai anchor; the anchor cavity includes an anchor cavity support plate, an anchor cavity top plate, an anchor cavity left side plate, and an anchor cavity right side plate, and the anchor cavity top plate is provided with an anchor rod through hole connecting the anchor cavity and the anchor chain cylinder; the anchor cavity left side plate includes a first left side plate and a second left side plate connected to the bottom end of the first left side plate, and the anchor cavity right side plate includes a first right side plate and a second right side plate connected to the bottom end of the first right side plate; the area between the first left side plate and the second left side plate is used to accommodate the claw tip of the anchor claw, and the second left side plate cooperates with the second right side plate to restrict the upward movement of the anchor claw, so as to prevent the tip of the anchor claw from entering the anchor chain cylinder and damaging the anchor chain cylinder.

[0006] Preferably, the floating structure is provided with an anchor hole boss under the anchor hole, and a top surface of the anchor hole boss is flush with a top surface of the anchor hole support plate; the anchor hole boss avoids direct contact with the Delter anchor when the anchor is received, thereby avoiding damage to the floating structure caused by collision.

[0007] Preferably, the anchor hole boss comprises a boss top plate and a boss bottom plate, and an end of the boss top plate away from the floating structure is smoothly connected to an end of the boss bottom plate away from the floating structure, so as to reduce wear between the anchor hole boss and the Delter anchor.

[0008] Preferably, an end of the boss bottom plate away from the floating structure is provided with a wear-resistant cylinder, and an end of the boss top plate away from the floating structure is connected to the wear-resistant cylinder through an arc-shaped wear-resistant plate, so as to improve the service life of the anchor hole boss.

[0009] Preferably, the wear-resistant cylinder and the arc-shaped wear-resistant plate are made of cast steel.

[0010] Preferably, the anchor hole boss comprises a boss side plate; the boss side plate is used to connect the boss top plate and the boss bottom plate; the boss side plate can strengthen the connection and improve the strength of the entire anchor hole boss.

[0011] Preferably, an acute angle α between the boss top plate and the boss bottom plate is equal to an angle β between the anchor jaw and the anchor rod when the Delter anchor is fully opened; in this way, when the Delter anchor is received in the state that the anchor jaw faces downward, the anchor jaw first contacts the boss bottom plate and is flipped downward to the maximum angle under the action of the boss bottom plate; the Delter anchor continues to move upward until the anchor jaw is tightly hooked with the boss bottom plate, thereby completing the recovery and fixation of the Delter anchor.

[0012] Preferably, the second left side plate and the second right side plate are both inclined plates that are inclined outward from top to bottom, and the inclined directions of the second left side plate and the second right side plate are symmetrically arranged about a center line of the anchor rod through hole; an acute angle between the second left side plate and the second right side plate matches an angle at a top corner of the anchor jaw; in this way, when the Delter anchor is received in the state that the anchor jaw faces upward, the Delter anchor can smoothly pass through the anchor hole boss and enter the anchor hole; because the space between the second left side plate and the second right side plate gradually decreases from bottom to top, when the anchor jaw is lifted upward to contact the second left side plate and the second right side plate on the left and right sides of the anchor jaw, the anchor jaw is clamped and cannot continue to move upward, thereby completing the recovery and fixation of the Delter anchor; at this time, the second left side plate and the second right side plate can also limit the left and right shaking of the anchor jaw, thereby ensuring the stability of the receiving.

[0013] Preferably, the second left side plate and the second right side plate are both arc-shaped plates that are inclined outward from top to bottom, and the second left side plate and the second right side plate are symmetrically arranged about the center line of the anchor rod through hole, so as to limit the upward movement of the anchor jaw by using the smallest gap between the two arc-shaped plates.

[0014] As described above, the anchor hole structure of the delta anchor of the present application has the following beneficial effects:

[0015] (1) According to the structure of the delta anchor, the left side plate of the anchor hole comprises a first left side plate and a second left side plate connected to the bottom end of the first left side plate, and the right side plate of the anchor hole comprises a first right side plate and a second right side plate connected to the bottom end of the first right side plate, and the up-moving position of the fluke is limited by the cooperation of the second left side plate and the second right side plate, so that when the fluke moves up to the limit position, the fluke tip is located in the area between the first left side plate and the first right side plate, and does not enter the hawse pipe, thereby ensuring the service life of the hawse pipe; in addition, the second left side plate and the second right side plate are both inclined plates inclined outward from top to bottom, wherein the inclination directions of the second left side plate and the second right side plate are symmetrically arranged about the center line of the anchor rod through hole, and the included acute angle of the inclination directions of the second left side plate and the second right side plate matches the angle at the top corner of the fluke, so that after the fluke moves up to the position, the second left side plate and the second right side plate can cooperate to limit the fluke from shaking, thereby avoiding damage to the anchor hole by the fluke.

[0016] (2) The anchor hole boss is arranged below the anchor hole, the anchor hole boss comprises a boss top plate and a boss bottom plate connected to the boss top plate, the boss top plate is required to be flush with the anchor hole support plate, and the included acute angle a of the boss top plate and the boss bottom plate is equal to the included angle β between the fluke and the anchor rod when the delta anchor is fully opened; in this way, when the delta anchor is lifted in the state that the fluke is downward, the upper end of the fluke first contacts the bottom of the anchor hole boss, so that the fluke is turned downward to the maximum folding angle, thereby achieving clamping and fixing through the folding opening of the delta anchor itself and the anchor hole boss; when the delta anchor is lifted in the state that the fluke is upward, the fluke can smoothly pass through the anchor hole boss and enter the anchor hole, and the second left side plate and the second right side plate of the anchor hole clamp the fluke, thereby ensuring that the fluke of the delta anchor can be fixed and recovered in different directions.

DETAILED DESCRIPTION

[0027] The embodiments of the present application will be described in detail by specific embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the content disclosed in the specification.

[0028] Please refer to Figs. 1-8. It should be understood that the structures, proportions, sizes, etc. shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the defined conditions that the present application can be implemented, so they do not have technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that the present application can produce, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the specification are only for the convenience of clear description, and are not used to limit the scope of the present application, and the change or adjustment of the relative relationship without substantially changing the technical content is also considered as the scope of the present application.

[0029] The present application provides an anchor pocket structure of a Delty anchor 02 to store and place the Delty anchor 02 when the floating structure such as a ship or offshore platform does not need to be anchored by the Delty anchor 02. As shown in Figs. 1 and 2, since the anchor fluke 022 of the Delty anchor 02 is in the shape of an isosceles triangle as a whole and has two sharp fluke tips with a small gap between the two fluke tips, the existing anchor pocket structure cannot meet the storage requirements of the Delty anchor 02. In view of this, the present application provides an anchor pocket structure specially used for storing the Delty anchor 02.

[0030] For the convenience of description, the following embodiments are described with the anchor pocket structure of the Delty anchor arranged on the ship, and the height direction of the ship is defined as the up-down direction, the left-right direction of the ship is defined as the left-right direction, and the bow-stern direction of the ship is defined as the front-rear direction; based on this, the direction of x in Fig. 3 is the front direction, the direction of y is the left direction, and the direction of z is the up direction.

[0031] In view of this, as shown in FIG. 3, FIG. 4 and FIG. 7, the anchor hole structure of the Delta anchor provided by the present application comprises an anchor hole 1 arranged on the ship body 01, the anchor hole 1 comprising an anchor hole support plate 11, an anchor hole top plate 12, an anchor hole left side plate 14 and an anchor hole right side plate 13, and the anchor hole support plate 11, the anchor hole top plate 12, the anchor hole left side plate 14 and the anchor hole right side plate 13 form a containing cavity for containing the fluke 022 of the Delta anchor 02; wherein the anchor hole top plate 12 is provided with a shank through hole for connecting the containing cavity and the hawse pipe 03; the anchor hole left side plate 14 comprises a first left side plate 14a and a second left side plate 14b connected to the bottom end of the first left side plate 14a, and the anchor hole right side plate 13 comprises a first right side plate 13a and a second right side plate 13b connected to the bottom end of the first right side plate 13a, and the second left side plate 14b and the second right side plate 13b can cooperate to limit the upward position of the fluke 022, so as to limit the fluke tip of the fluke 022 in the area between the first left side plate 14a and the second left side plate 13a; since the fluke tip of the fluke 022 cannot pass through the shank through hole to enter the hawse pipe 03, the service life of the hawse pipe 03 is effectively guaranteed, and the problem of poor anchor winding and unwinding caused by the deformation of the hawse pipe 03 is avoided; in this embodiment, the first left side plate 14a and the second left side plate 13a are arranged in parallel and symmetrically about the center line of the shank through hole.

[0032] In addition, in order to avoid the fluke tip of the fluke 022 from scratching the anchor hole top plate 12, a certain gap is required between the fluke tip of the fluke 022 and the anchor hole top plate 12 after the fluke 022 is moved upward.

[0033] It can be understood that the way in which the second left side plate 14b and the second right side plate 13b cooperate to limit the upward position of the fluke 022 includes but is not limited to the following several ways:

[0034] Embodiment one:

[0035] Two limiting protrusions are arranged on the inner surfaces of the second left side plate 14b and the second right side plate 13b in opposition, and the upward position of the fluke 022 is limited by the two limiting protrusions arranged in opposition.

[0036] Embodiment two:

[0037] The second left side plate 14b and the second right side plate 13b are arranged in opposition and adopt inwardly protruding angle plates, and the upward position of the fluke 022 is limited by the angles of the two angle plates.

[0038] Embodiment three:

[0039] The second left side plate 14b and the second right side plate 14a are both arc-shaped plates that are inclined outward from top to bottom, and the second left side plate 14b and the second right side plate 14a are symmetrically arranged about the center line of the shank through hole, so as to limit the upward position of the fluke 022 by the smallest gap between the two arc-shaped plates.

[0040] Embodiment Four

[0041] The second left side plate 14b and the second right side plate 13b are both inclined plates inclined outward from top to bottom, and the inclination direction of the second left side plate 14b is symmetrically arranged with the inclination direction of the second right side plate 13b about the center line of the anchor rod through hole; in addition, the acute angle between the second left side plate 14b and the second right side plate 13b needs to match the angle at the top corner of the anchor claw 022, and the gap between the upper end of the second left side plate 14b and the upper end of the second right side plate 13b needs to be greater than the width of the top end of the anchor claw 022 and less than the width of the bottom end of the anchor claw 022; in this way, when the delter anchor 02 enters the anchor hole 1 in the state that the anchor claw 022 is upward, since the space between the second left side plate 14b and the second right side plate 14a gradually decreases from bottom to top, when the anchor claw 022 is lifted upward to contact the second left side plate 14b and the second right side plate 14a on the left and right sides of the anchor claw respectively, it will be clamped and cannot continue to move upward, thereby completing the recovery and fixation of the delter anchor; at this time, the second left side plate 14b and the second right side plate 13b can also limit the left and right shaking of the anchor claw 022, ensuring the stability of the storage.

[0042] Based on the processing difficulty and storage stability, the application preferably adopts the above-mentioned embodiment 4.

[0043] In a preferred embodiment, in order to avoid the delter anchor 02 from colliding with the ship body 1 when it is lifted upward for storage, as shown in FIG. 6, an anchor hole boss 2 is arranged on the outer plate of the ship body below the anchor hole 1, and the top surface of the anchor hole boss 2 is flush with the top surface of the anchor hole support plate 11; since the anchor hole boss 2 protrudes from the outer plate of the ship body, the delter anchor 02 will not contact and collide with the outer plate of the ship body when it is lifted for storage, effectively ensuring the service life of the outer plate of the ship body.

[0044] In a specific embodiment, as shown in FIG. 5, the anchor hole boss 2 includes a boss top plate 21 and a boss bottom plate 22, and the end of the boss top plate 21 away from the outer plate of the ship body is smoothly connected with the end of the boss bottom plate 22 away from the outer plate of the ship body, so as to avoid the local position of the anchor hole boss 2 from being excessively worn.

[0045] In a more specific embodiment, as shown in FIG. 5, the end of the boss bottom plate 22 away from the outer plate of the ship body is provided with a wear-resistant cylinder 23, and the end of the boss top plate 21 away from the outer plate of the ship body is connected with the wear-resistant cylinder 23 through an arc-shaped wear-resistant plate 24, and the wear-resistant cylinder 23 and the arc-shaped wear-resistant plate 24 are made of cast steel, so as to improve the wear resistance of the anchor hole boss 2.

[0046] In order to improve the strength of the anchor hole boss 2, as shown in FIG. 5, the anchor hole boss 2 further includes a boss side plate 25 for strengthening the connection between the boss top plate 21 and the boss bottom plate 22; in this embodiment, the boss side plate 25 has two, which are respectively arranged on the left and right sides of the boss top plate 21.

[0047] Since the fluke 022 of the Delter anchor 02 can swing relative to the anchor shaft 021, the Delter anchor 02 can be in a state of the fluke 022 upward or the fluke 022 downward when hanging and lifting, so as to ensure that the Delter anchor 02 can be properly stored in any state, it is required that the acute angle α between the top plate 21 and the bottom plate 22 and the angle β between the fluke 022 and the anchor shaft 021 when the Delter anchor 02 is fully opened satisfy: 0°≤α-β≤3°. In the embodiment, in order to avoid the situation that the fluke 022 of the Delter anchor 02 is in hard contact with the fluke boss 2 when being stored in place in the downward state, the acute angle α between the top plate 21 and the bottom plate 22 and the angle β between the fluke 022 and the anchor shaft 021 when the Delter anchor 02 is fully opened need to be equal.

[0048] The process schematic diagram of the Delter anchor 02 in the state of the fluke 022 upward is shown in FIGS. 6 and 7. When the Delter anchor 02 is pulled upward, the bottom end of the fluke 022 first contacts the fluke boss 2 and is turned downward under the action of the fluke boss 2 by a certain angle, so that the fluke 022 smoothly passes through the fluke boss 2 and enters the fluke hole 1, thereby clamping the fluke 022 by the second left side plate 14b and the second right side plate 13b of the fluke hole 1, and achieving smooth storage of the Delter anchor 02 in the state of the fluke 022 upward.

[0049] The process schematic diagram of the Delter anchor 02 in the state of the fluke 022 downward is shown in FIG. 8. When the Delter anchor 02 is pulled upward, the top end of the fluke 022 first contacts the bottom of the fluke bottom plate 22 and is turned downward to the maximum folding angle under the action of the fluke bottom plate 22, thereby achieving clamping and fixing by the folding opening of the Delter anchor 02 itself and the fluke boss 2, and achieving smooth storage of the Delter anchor 02 in the state of the fluke 022 downward.

[0050] As can be seen from the above, the fluke hole structure of the present application can conveniently achieve proper storage of the Delter anchor 02 in different states, and effectively improve the smoothness of storage of the Delter anchor 02. Moreover, when the Delter anchor 02 is stored in the fluke hole 1, the top end of the fluke 022 is limited in the upward position, so that the fluke tip of the Delter anchor 02 can be prevented from piercing the fluke top plate 12 or entering the anchor chain cylinder 03 to cause the anchor chain cylinder 03 to be squeezed and deformed, thereby ensuring the smoothness of subsequent anchor storage and release. The fluke hole structure of the present application fills the gap of the Delter anchor 02 fluke hole storage, and has high industrial application value.

[0051] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
