Description

Technical Field

[0001] This application relates to the technical field of ships, and particularly to an anchor and a ship. Background Art

[0002] Currently, the general ship mooring system adopts the gravity flipping type anchor recovery technology. When the ship weighs anchor, relying on its own center of gravity gravity, the anchor continuously flips during the process of pulling up and lowering the anchor chain. By using the synergistic effect of gravity and the pulling force of the anchor chain, the anchor is gradually adjusted to the forward state and finally pulled into the anchor recess.

[0003] Currently, to ensure that the anchor is pulled into the anchor recess in the forward state, it is necessary to strictly control the pulling speed of the anchor chain, which makes the process of weighing anchor time-consuming and seriously affects the berthing efficiency of the ship. At the same time, the operator needs to have rich experience and a high professional level to accurately grasp the pulling speed of the anchor chain and the state of the anchor, resulting in high labor costs and the risk of human operation errors. Secondly, if the pulling speed of the anchor chain is too fast, or affected by factors such as water flow and the state of the anchor itself, the anchor cannot be flipped in place in time, easily causing the phenomenon of jamming the anchor, resulting in the anchor being unable to return to its normal position, and even damaging the structure of the anchor recess, causing irreversible damage to the ship mooring system and posing a major safety hazard.

[0004] However, currently, there are still many difficulties in solving these problems. To conduct technological research and development on the existing anchor structure design and anchor chain control method, it is necessary to integrate multidisciplinary knowledge such as mechanical engineering and fluid mechanics. The technical difficulty is great and the research and development cost is high. It is not only difficult to achieve a breakthrough innovation in a short time but also difficult to be comprehensively promoted and applied in a short time. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide an anchor and a ship, which can solve the above problems existing in the prior art.

[0006] To achieve the above object, this application adopts the following technical solutions: On the one hand, as an embodiment of this application, an anchor is provided, including: An anchor rod, the first end of the anchor rod is connected to the anchor chain; An anchor claw, the anchor claw is connected to the second end of the anchor rod; and A support member, the support member is located on one side of the anchor rod close to the first end of the anchor rod and protrudes from the outer surface of the anchor rod.

[0007] Preferably, the inner edge of the support member fits the outer surface of the anchor rod; the outer edge of the support member is opposite to the inner edge of the support member; when the anchor is pulled into the anchor recess, the outer edge of the support member abuts against the wall surface of the anchor recess.

[0008] Preferably, the outer edge of the support member is arc-shaped.

[0016] The beneficial effects of the present application are as follows: In the present application, the support member provided on the side of the anchor rod close to the anchor chain provides a fulcrum for the anchor. During the process of pulling the anchor into the anchor recess, the anchor rod is jacked up through this fulcrum, causing the overall center of gravity of the anchor to shift and making it impossible to maintain balance.

[0021] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0022] In the description of this application, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.

[0023] In this application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but are in contact through other features between them.

[0024] Figure 1 Schematic diagram of the ship anchor structure provided by the embodiment of this application, Figure 2 is Figure 1 the partial enlarged structure diagram of area A in. Please refer to Figure 1 and Figure 2 As shown, in an embodiment of this application, a ship anchor is provided, including: an anchor rod 100, an anchor chain, an anchor claw 200, and a support member 300; the first end of the anchor rod 100 is connected to the anchor chain; the anchor claw 200 is connected to the second end of the anchor rod 100; the support member 300 is located on one side of the anchor rod 100 close to the first end of the anchor rod 100 and protrudes from the outer surface of the anchor rod 100.

[0025] In this application, the support member 300 provides a fulcrum for the anchor during the process of pulling the anchor into the anchor recess, thereby lifting the anchor rod 100 and causing the overall center of gravity of the anchor to shift so that it cannot maintain balance. Under the combined action of gravity and pulling force, the freely movable anchor claw 200 quickly completes a flipping action, adjusting its posture from the lateral or reverse posture during ground gripping to the forward state, so as to ensure that the anchor claw 200 is smoothly pulled into the anchor recess in the forward state. This application can break through the upper pull speed limit, realize the rapid retraction of the anchor, greatly shorten the anchor-raising time, significantly improve the efficiency of ship berthing and unberthing, reduce port waiting time, lower operating costs, and at the same time reduce reliance on manpower and improve the standardization of operation.

[0026] It should also be supplemented here that the structure of the anchor recess mainly includes an anchor chain tube and an anchor storage cavity. The upper end of the anchor chain tube is connected to the hull deck, the lower end of the anchor chain tube leads to the anchor storage cavity, and the anchor chain tube is the vertical movement channel for the anchor chain and the anchor rod 100. The anchor storage cavity is mainly used to accommodate the anchor claw 200.

[0027] That is to say, during the process of retrieving the anchor, as the anchor chain contracts, the first end of the anchor rod 100 connected to the anchor chain enters the anchor chain tube of the anchor recess, and the support member 300 provided protruding from the first end of the anchor rod 100 abuts against the anchor chain tube of the anchor recess. At this time, the support member 300 provides a fulcrum for the anchor. Considering that the overall center of gravity of the anchor is biased towards the second end of the anchor rod 100 and the anchor claw 200 connected to the second end of the anchor rod 100, relatively, the first end of the anchor rod 100 where the support member 300 is located is far from the center of the anchor.

[0028] In an embodiment of this application, the inner edge 301 of the support member 300 fits the outer surface of the anchor rod 100; the outer edge 302 of the support member 300 faces away from the inner edge 301 of the support member 300; when the anchor is pulled into the anchor recess, the outer edge 302 of the support member 300 abuts against the wall surface of the anchor recess.

[0029] In an alternative embodiment, the support member 300 and the anchor rod 100 can be welded to achieve the fitting of the inner edge 301 of the support member 300 with the outer surface of the anchor rod 100.

[0030] In an alternative embodiment, the support member 300 and the anchor rod 100 can be integrally formed by forging to achieve the fitting of the inner edge 301 of the support member 300 with the outer surface of the anchor rod 100.

[0031] In an alternative embodiment, the support member 300 and the anchor rod 100 can be integrally formed by casting and inlaying to achieve the fitting of the inner edge 301 of the support member 300 with the outer surface of the anchor rod 100.

[0032] In an alternative embodiment, the support member 300 and the anchor rod 100 may be bonded and pressed together so that the inner edge 301 of the support member 300 fits against the outer surface of the anchor rod 100.

[0033] Further explanation is needed regarding the structure of the anchor rod 100. The anchor rod 100 includes an anchor shackle 101 and a rod body 102. The first end of the anchor shackle 101 is connected to the anchor chain; the first end of the rod body 102 is hingedly connected to the second end of the anchor shackle 101.

[0034] In an alternative embodiment, the support member 300 is disposed on the anchor shackle 101, as Figure 1 and Figure 2 shown. Specifically, the support member 300 is connected to the anchor shackle 101 and protrudes from the outer surface of the anchor shackle 101. Since the rod body 102 and the anchor chain are connected through the anchor shackle 101, that is to say, the anchor shackle 101 will enter the anchor chain barrel of the anchor recess before the first end of the rod body 102. Disposing the support member 300 on the anchor shackle 101 can reserve more sufficient adjustment time and space for adjusting the position of the anchor claw 200.

[0035] In an alternative embodiment, the support member 300 is disposed on the rod body 102. Specifically, the support member 300 is connected to the first end of the rod body 102 and protrudes from the outer surface of the rod body 102. Disposing the support member 300 on the rod body 102, the support member 300 directly provides a fulcrum for the rod body 102, causing the rod body 102 and the anchor claw 200 connected to the rod body 102 to be lifted, thereby generating a center of gravity shift, destroying the balance state of the ship anchor, and causing the ship anchor to drive and quickly flip to the forward state under the action of gravity and be stored in the anchor storage cavity of the anchor recess in the forward state. Such an arrangement is more stable in terms of force. However, it should be noted that when the support member 300 is disposed on the rod body 102, it is necessary to ensure that the height of the support member 300 protruding from the rod body 102 is higher than that of the anchor shackle 101 so that the support member 300 can serve as the fulcrum of the ship anchor.

[0036] In an alternative embodiment, the outer edge 302 of the support member 300 is arc-shaped. Here, it mainly means that during the process of retracting the anchor, the outer edge 302 of the support member 300 abuts against the end face of the anchor chain barrel of the anchor recess, generally the side face of the outer edge 302 of the support member 300.

[0037] Setting the outer edge 302 of the support member 300 to be arc-shaped can more effectively disperse the pressure exerted by the hawsepipe of the anchor pocket when the outer edge 302 of the support member 300 abuts against the hawsepipe of the anchor pocket, avoid local excessive wear, and extend the service life of the support member 300. At the same time, setting the outer edge 302 of the support member 300 to be arc-shaped makes a point contact formed between the outer edge 302 of the support member 300 and the hawsepipe of the anchor pocket, and using this point contact as the fulcrum of the whole ship anchor, so that even in severe sea conditions, it can help the ship anchor complete the flipping and resetting action efficiently. Even if the ship shakes violently due to wind and waves, it can ensure that the anchor claw 200 smoothly enters the anchor pocket in a positive posture, providing a solid guarantee for the safe navigation of the ship.

[0038] In an alternative embodiment, the contour shape of the support member 300 is triangular. It should be noted here that the contour shape of the support member 300 can be understood as the shape formed by enclosing the inner edge 301 and the outer edge 302 of the support member 300.

[0039] Here, the contour shape of the support member 300 is set to a wing-like triangular structure, so that the support member 300 has a large contact area and a unique force-bearing structure. When contacting the wall surface of the anchor pocket, the wing-like triangular structure can generate a large moment, jack up the anchor rod 100 more efficiently, and accelerate the flipping of the anchor claw 200.

[0040] In an alternative embodiment, a first transition inclined surface 303 is provided on one side of the support member 300 close to the first end of the anchor rod 100, and a second transition inclined surface 304 is provided on one side of the support member 300 close to the second end of the anchor rod 100; wherein, the included angle between the first transition inclined surface 303 and the central axis of the anchor rod 100 is smaller than the included angle between the second transition inclined surface 304 and the central axis of the anchor rod 100.

[0041] In this embodiment, the first transition inclined surface 303 and the second transition inclined surface 304 are arranged in sequence according to the order of the hawsepipes entering the anchor pocket, so that the streamline design of the first transition inclined surface 303 of the support member 300 can effectively reduce the water flow resistance and reduce the energy loss during the anchor retraction process. Correspondingly, the second transition inclined surface 304 and the first transition inclined surface 303 are arranged in sequence according to the order of the ship anchor entering the water, so that the streamline design of the second transition inclined surface 304 of the support member 300 can effectively reduce the water flow resistance and reduce the energy loss during the ship anchor entering the water process.

[0042] In an alternative embodiment, a plurality of the support members 300 are arranged circumferentially around the anchor rod 100. Such an arrangement increases the contact area between the support members 300 and the anchor rod 100, enables more uniform force transmission, and reduces local stress concentration. A plurality of support members 300 can all contact the wall surface of the anchor cavity, forming a plurality of fulcrums, making the circumferential force on the anchor rod 100 more balanced, thus jacking up the anchor rod 100 more stably and prompting the anchor claw 200 to flip.

[0043] In an alternative embodiment, a plurality of the support members 300 are arranged axially around the anchor rod 100. Such an arrangement increases the contact area between the support members 300 and the anchor rod 100, enables more uniform force transmission, and reduces local stress concentration. A plurality of support members 300 can all contact the wall surface of the anchor cavity, forming a plurality of fulcrums, making the axial force on the anchor rod 100 more balanced, thus jacking up the anchor rod 100 more stably and prompting the anchor claw 200 to flip.

[0044] In an alternative embodiment, a plurality of the support members 300 are helical, and a plurality of support members 300 are distributed along the axial direction of the anchor rod. Such an arrangement increases the contact area between the support members 300 and the anchor rod 100 and reduces local stress concentration. When the ship anchor is pulled into the anchor cavity, the entire circumferential surface of the ring structure can contact the wall surface of the anchor cavity, making the circumferential and axial forces on the anchor rod 100 more balanced, thus jacking up the anchor rod 100 more stably and prompting the anchor claw 200 to flip.

[0045] In an alternative embodiment, the support member 300 is a block structure. Selecting a block structure for the support member 300 can ensure that there is sufficient contact area between the support member 300 and the anchor rod 100, which is beneficial to reducing local stress concentration.

[0046] In an alternative embodiment, the support member 300 is a ring-shaped sleeve structure sleeved on the anchor rod 100. Such an arrangement increases the contact area between the support member 300 and the anchor rod 100 and reduces local stress concentration. When the ship anchor is pulled into the anchor cavity, the entire circumferential surface of the ring-shaped sleeve structure can contact the wall surface of the anchor cavity, making the circumferential force on the anchor rod 100 more balanced, thus jacking up the anchor rod 100 more stably and prompting the anchor claw 200 to flip.

[0047] In an alternative embodiment, the support member 300 can be a rod-shaped structure. Usually, the rod-shaped structure is slender and arranged perpendicular to the axial direction of the anchor rod 100. Selecting a rod-shaped structure for the support member 300 occupies less space and is suitable for the design of ship anchors with space limitations.

[0048] A support member 300 can be provided here. Specifically, a single rod-shaped structure can be provided. The single rod-shaped support member 300 can be flexibly installed at a specific position of the anchor rod 100. By adjusting the length and inclination angle of the rod body 102, the fulcrum position and the force application direction in contact with the wall surface of the anchor hole can be accurately controlled to adapt to different anchor hole structures.

[0049] Multiple support members 300 can be provided here. Specifically, multiple rod-shaped structures can be provided. The form of the combination of multiple rod bodies 102 can provide stronger support force. When one of the rod bodies 102 contacts the wall surface of the anchor hole, the other rod bodies 102 can play an auxiliary support and balancing role, enhancing the stability of the ship anchor's flipping.

[0050] In an embodiment of the present application, a ship is also provided, which adopts the ship anchor as described above. By providing a support member on the side of the anchor rod close to the anchor chain, a fulcrum is provided for the ship anchor. During the process of the ship anchor being pulled into the anchor hole in a side-overturned state, the anchor rod is lifted by this fulcrum, causing the overall center of gravity of the ship anchor to shift and making it impossible to maintain balance, thereby enabling the anchor claw to quickly flip to the forward state to ensure that the anchor claw is smoothly pulled into the anchor hole in the forward state. The present application can break through the upper-pulling speed limit, achieve the rapid return of the anchor, greatly shorten the anchor-raising time, significantly improve the berthing efficiency of the ship, reduce the port waiting time, lower the operation cost and safety risk, and at the same time reduce the reliance on manpower and improve the standardization degree of operation.
