Abstract
Description
Technical Field
[0001] This application relates to the technical field of ships, and in particular to a buffer type bow structure and a ship. Background Art
[0002] The bow column of a ship is the component at the very front of the ship's bow and is an important part of the hull. Its function is to connect the side shell plates, the deck, and the end of the keel, and to strengthen the connection strength at the bow to ensure that the bow is not easily deformed.
[0003] The bow columns of the prior art are usually made of solid-structured steel. The bow columns made of solid-structured steel have relatively high rigidity and poor toughness. When impacted, the impact force generated by the collision is directly transmitted to the hull, resulting in damage to the hull. Moreover, the overall use of solid-structured steel makes it heavy, uses a lot of materials, and is time-consuming and laborious to manufacture.
[0004] Therefore, it is very necessary to design a bow column structure and a ship with good buffering performance and low cost. Summary of the Utility Model
[0005] This application aims to solve one of the technical problems in the related art to a certain extent. For this purpose, this application provides a buffer type bow column structure and a ship.
[0006] To achieve the above object, this application adopts the following technical solution: A buffer type bow column structure is fixedly connected to the very front of the bow of a ship. The buffer type bow column structure includes a bow column body, and the bow column body includes a hollow tube and reinforcing ribs. The hollow tube is fixedly connected to the side shell plates on both sides of the bow, and reinforcing ribs are fixedly connected to the outer wall of the side of the hollow tube facing the interior of the ship along the hollow tube.
[0007] The buffer type bow column structure of the present utility model makes the bow column collapse and deform inward when a collision occurs by setting the bow column body as a hollow tube, which plays a role in unloading force and buffering, reducing the risk of damage to the hull during a collision. By setting reinforcing ribs on the outer wall of the side of the hollow tube facing the interior of the ship, the support strength of the bow column is improved, preventing the bow column from deforming inward into the hull and damaging the hull when encountering a collision force.
[0008] Further, the reinforcing ribs extend from one end of the hollow tube to the other end, and the reinforcing ribs are perpendicular to the outer side wall of the hollow tube.
[0009] Further, the hollow tube is a hollow circular tube, and the hollow tube bends and extends from the bow deck along the joint of the side shell plates on both sides towards the bottom of the hull.
[0010] Further, the hollow tube is tangent to the side shell plates on both sides of the bow.
[0011] Furthermore, the hollow tube body is configured as a steel tube.
[0012] Furthermore, the hollow tube body is connected to the side plates on both sides of the bow by welding.
[0013] Furthermore, the wall thickness of the hollow circular tube is set to 5 to 15 mm.
[0014] Furthermore, the reinforcing rib is connected to the hollow tube body by welding.
[0015] Furthermore, the reinforcing ribs are made of steel plates with a width of 50 to 150 mm and a thickness of 5 to 15 mm.
[0016] In addition, the present application also provides a ship, including a bow, wherein the front end of the bow is provided with a buffer-type bow column structure as described in any of the above technical solutions. The reasoning process of the beneficial effects of the ship provided by the present application and the buffer-type bow column structure is similar, and will not be repeated here.

[0022] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.
[0023] As used herein, the phrase "one embodiment", "example" or "instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearances of the phrase "in one embodiment" in various places in the specification do not necessarily all refer to the same embodiment.
[0024] As Figure 1 , Figure 2 As shown, a buffer bow structure is fixedly connected to the foremost end of the bow of a ship. The buffer bow structure includes a bow body 10, and the bow body 10 includes a hollow tube body 11 and a reinforcing rib 12. The hollow tube body 11 is fixedly connected to the side plates 20 on both sides of the bow. A reinforcing rib 12 arranged along the hollow tube body 11 is fixedly connected to the outer wall of the side of the hollow tube body 11 facing the interior of the ship.
[0025] In the buffer bow structure of this embodiment, by setting the bow body 10 as a hollow tube body 11, the bow can collapse and deform inward when a collision occurs, playing a role in unloading force and buffering, reducing the risk of damage to the hull during a collision. By arranging a reinforcing rib 12 on the outer wall of the side of the hollow tube body 11 facing the interior of the ship, the support strength of the bow is improved. At the same time, when the bow collides, it prevents the hollow tube body 11 from bending inward into the hull and damaging the hull, that is, it prevents the bow from deforming inward into the hull and damaging the hull when encountering a collision force.
[0026] As an implementation manner, the reinforcing rib 12 extends from one end of the hollow tube body 11 to the other end, and the reinforcing rib 12 is arranged perpendicular to the outer side wall of the hollow tube body 11. Arranging the reinforcing rib 12 perpendicular to the outer side wall of the hollow tube body 11 can better support the hollow tube body 11 and prevent the hollow tube body 11 from bending inward into the hull when impacted by an external force.
[0027] As an implementation manner, the hollow tube body 11 is set as a hollow circular tube, and the hollow tube body 11 bends and extends from the bow deck along the joint of the side plates 20 on both sides to the bottom of the hull. Setting the hollow tube body 11 as a hollow circular tube can enhance the impact resistance of the hollow tube body 11, prevent the hollow tube body 11 from deforming and being damaged under a small impact force, and improve the strength of the hollow tube body 11. Bending and extending the hollow tube body 11 from the bow deck along the joint of the side plates 20 on both sides to the bottom of the hull can better protect the bow of the hull, even if the hollow tube body 11 wraps around the foremost end of the bow of the hull.
[0028] As an implementation manner, the hollow tube body 11 is tangent to the side plates 20 on both sides of the bow. The connection setting method in which the hollow tube body 11 is tangent to the side plates 20 on both sides of the bow can better buffer the external impact force and prevent the side plates 20 on both sides of the bow of the hull from deforming under the action of the external impact force.
[0029] Specifically, the hollow tube body 11 is a steel tube. The hollow tube body 11 made of a steel tube can well balance the support strength of the hollow tube body 11 and the deformation capacity when impacted, thereby improving the overall performance of the bow column.
[0030] As an implementation mode, the hollow tube body 11 is welded to the side plates 20 on both sides of the bow. The hollow tube body 11 is welded to the side plates 20 on both sides of the bow, which is easy to operate and has high connection strength.
[0031] As an implementation method, the wall thickness of the hollow circular tube is set to 5-15 mm. Appropriate wall thickness can better balance the connection strength and anti-collision capability of the hollow tube body 11.
[0032] As an implementation mode, the reinforcing rib 12 is welded to the hollow tube body 11. The reinforcing rib 12 is welded to the hollow tube body 11, which is easy to operate and has high connection strength.
[0033] As an implementation method, the reinforcing rib 12 is set to be a steel plate with a width of 50 to 150 mm and a thickness of 5 to 15 mm.
[0034] In a specific embodiment, the hollow tube body 11 is set as a circular steel tube with a diameter of 108 mm and a wall thickness of 10 mm, the reinforcing rib 12 is set as a steel plate with a width of 120 mm and a thickness of 10 mm, the reinforcing rib 12 is arranged perpendicular to the outer wall of the hollow tube body 11 toward the inner side of the hull, and the reinforcing rib 12 is parallel to the central axis of the hull.
[0035] This embodiment also provides a ship, including a bow, wherein the front end of the bow is provided with a buffer-type bow column structure as described in any technical solution of the above embodiments. The reasoning process of the beneficial effects of the ship provided in this application and the above buffer-type bow column structure is similar, and will not be repeated here.
[0036] To sum up, the buffer-type bow structure of the present embodiment enables the bow body 10 to be configured as a hollow tube body 11 so that the bow can collapse and deform inwardly when a collision occurs, thereby unloading and buffering the bow and reducing the risk of damage to the hull in a collision. The support strength of the bow is increased by providing reinforcing ribs 12 on the outer wall of the hollow tube body 11 on the side facing the interior of the ship. At the same time, when the bow collides, the hollow tube body 11 is prevented from bending inwardly to damage the hull, that is, the bow is prevented from deforming inwardly to damage the hull when encountering a collision force.
[0037] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
