Description

Technical Field

[0001] The utility model generally relates to the field of ship hulls, and in particular to a hawser barrel cover and a ship hull used in a narrow space. Background Art

[0002] The hawser serves as a channel for the anchor chain during heaving and dropping anchor, and is used to store the anchor while the vessel is underway. Common hawser chain structures must ensure that the anchor can be quickly and freely cast out and smoothly stored in. The hawser chain is typically equipped with a cover to provide some protection from the anchor chain, while ensuring that this protection does not affect its operation.

[0003] However, since the deck opening of the bow anchor chain barrel of some ships is located in a relatively small space away from the bulwark, if it is designed as a conventional pull-out cover, the cover cannot be smoothly pulled out due to space constraints, affecting the normal use of the anchor chain barrel. Utility Model Content

[0033] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Please refer to Figure 1 This embodiment provides a chain drum cover 10 for use in a narrow space, comprising:

[0036] a first cylinder cover 11, which is mounted on the anchor chain cylinder 30 and covers a portion of the anchor chain cylinder 30. The mounting point of the first cylinder cover 11 is a first rotation center 13, and the first cylinder cover 11 can rotate around the first rotation center 13 in the plane where the first cylinder cover 11 is located;

[0037] a second cylinder cover 12, which is mounted on the anchor chain cylinder 30 and covers a portion of the anchor chain cylinder 30. The mounting point of the second cylinder cover 12 is a second rotation center 14, and the second cylinder cover 12 can rotate around the second rotation center 14 in the plane where the second cylinder cover 12 is located;

[0038] An opening 20 is defined between the first barrel cover 11 and the second barrel cover 12 . The opening 20 exposes a portion of the hawser barrel 30 and is used for passing the anchor chain in the hawser barrel 30 .

[0039] The chain barrel cover 10 provided in this embodiment covers the chain barrel 30 with two barrel covers. At the same time, an opening is left in the barrel covers for the anchor chain in the chain barrel to pass through, so as to facilitate the normal placement and use of the anchor chain. The installation point of each barrel cover is also the rotation center. Each barrel cover can rotate around the rotation center in the current plane, leaving the position where the chain barrel is located, exposing the chain barrel and forming an open shape of the chain barrel. The barrel cover structure requires less space and can be used in compact places, thus saving space on the hull.

[0040] The anchor chain cover 10 provided in this embodiment is in the form of a multi-part assembly, each part is arranged in a rotating form, and during the rotation process, it moves away from and approaches the anchor chain, forming different states of the anchor chain closed and opened. This form can be used in a narrow space, such as Figure 1 As shown, preferably, a rotatable first cylinder cover 11 and second cylinder cover 12 are provided, and the first cylinder cover 11 and second cylinder cover 12 are mounted on the hull by bolts, and the first cylinder cover 11 and second cylinder cover 12 are clearance-matched with the bolts, so that the first cylinder cover 11 and second cylinder cover 12 can rotate around the fixed bolts, and the rotation is a rotation within a plane range, and the required longitudinal space is small.

[0041] like Figure 1 and Figure 3 As shown, the first cylinder cover 11 and the second cylinder cover 12 in this embodiment are arranged in a symmetrical form, and the structures and shapes of the two are also the same. Preferably, the mounting point of the first cylinder cover 11 and the mounting point of the second cylinder cover 12 are arranged at the same position, and the two are arranged side by side to form Figure 1 and Figure 3 The structure shown, Figure 1This is a schematic diagram of the first barrel cover 11 and the second barrel cover 12 when they are closed. When they need to be opened, the first barrel cover 11 on the left side rotates counterclockwise, and the second barrel cover 12 on the right side rotates clockwise to realize the open state of the anchor chain barrel cover 10. The first barrel cover 11 and the second barrel cover 12 are installed in the same way. Both are provided with fixed bolts at the installation points. The bolts are installed on the hull. The first barrel cover 11 and the second barrel cover 12 are provided with through holes. The bolts pass through the through holes to form a clearance fit. The first barrel cover 11 and the second barrel cover 12 can both rotate clockwise and counterclockwise around the installed bolts. The anchor chain barrel cover 10 provided in this embodiment is structurally arranged in a symmetrical form. When the first barrel cover 11 and the second barrel cover 12 are rotated to open, there is a certain requirement for the space on both sides below the anchor chain barrel. If the position space where the anchor chain barrel 30 is located is an irregular shape, the installation points of the first barrel cover 11 and the second barrel cover 12 can be set at different positions. For example, the installation point of the first barrel cover 11 is located at the current Figure 1 The position shown, the installation point of the second cylinder cover 12 is located at Figure 1 The position of the fixing device 19 in the second cylinder cover 12 is opened when the second cylinder cover 12 rotates counterclockwise. Therefore, the rotation center and the fixing position of the cylinder cover in this embodiment can be selected and adjusted according to the actual space requirements and are not limited to Figure 1 and Figure 3 The form shown in .

[0042] like Figure 3 As shown, the cylinder cover in this embodiment is installed on the hull, and an anti-friction round rod is provided under the cylinder cover. This structure provides certain support and anti-friction effects on the cylinder cover.

[0043] The anchor barrel cover 10 further comprises an opening 20 which includes a first opening 22 and a second opening 21 which are connected to each other. The first opening 22 is arranged near the center of the anchor barrel. The edge of the first opening 22 is in an arc shape, and the radius of the arc is positively correlated with the size of the anchor chain in the anchor barrel.

[0044] The second opening 21 is disposed close to an edge of the hawse barrel 30 , and the edge of the second opening 21 is a straight line.

[0045] like Figure 1As shown, the anchor chain barrel cover 10 provided in this embodiment does not completely cover the anchor chain barrel 30, but is provided with an opening 20 for the anchor chain to pass through, which does not affect the placement of the anchor chain. Among them, it is preferred to set the opening 20 to an irregular shape so that the structure of the opening 20 matches the shape of the anchor chain, and then the anchor chain barrel cover 10 has a better covering effect on the anchor chain barrel. Specifically, the opening 20 is divided into two connected parts, the second opening 21 is a rectangular structure, and the first opening 22 is a semicircular structure. The arc of the edge of the first opening 22 can refer to the shape of the anchor chain to form a matching arc edge. At the same time, the second opening 21 is set larger to meet the movement of the anchor chain at the second opening 21. The anchor chain barrel cover 10 in this embodiment is to first install the two semicircular first barrel covers 11 and the second barrel covers 12 on the anchor chain barrel, and then cut them after installation to form the following Figure 1 Preferably, the angle between the straight edge of the second opening 21 and the symmetry axis is 15°.

[0046] The anchor chain cylinder cover 10 is optional. The first cylinder cover 11 is provided with a first reinforcing rib 15, and the longitudinal section of the first reinforcing rib 15 is triangular. The second cylinder cover 12 is provided with a second reinforcing rib 16, and the longitudinal section of the second reinforcing rib 16 is triangular.

[0047] In order to strengthen the strength of the first cylinder cover 11 and the second cylinder cover 12, a reinforcing rib structure is provided on both the first cylinder cover 11 and the second cylinder cover 12. The first cylinder cover 11 is provided with a first reinforcing rib 15, and the second cylinder cover 12 is provided with a second reinforcing rib 16. The first reinforcing rib 15 or the second reinforcing rib 16 can be continuous, discontinuous, or staggered, and the selection is made based on the convenience of processing. Figure 1 and Figure 2 As shown, in this embodiment, the first cylinder cover 11 and the second cylinder cover 12 are preferably arranged in a symmetrical form, and the arrangement position and structure of the first reinforcing rib 15 and the second reinforcing rib 16 are also symmetrical, which makes the appearance more beautiful. In addition, the first reinforcing rib 15 and the second reinforcing rib 16 are arranged in a triangular shape in longitudinal section, and are respectively formed by bending steel of a certain thickness and then welded to the plate of the cylinder cover.

[0048] like Figure 1 As shown, the reinforcing ribs provided in this embodiment are continuous long strips and are arranged at the longest part of each cylinder cover as much as possible to facilitate the arrangement of the reinforcing ribs.

[0049] Optionally, the first reinforcing rib 15 is provided on the cylinder cover with a first handle 17 , and the first handle 17 is provided at an end of the first cylinder cover 11 away from the first rotation center 13 .

[0050] A second handle 18 is provided on the cylinder cover of the second reinforcing rib 16 . The second handle 18 is disposed at an end of the second cylinder cover 12 away from the second rotation center 14 .

[0051] like Figure 1 As shown, a handle structure is also provided on each cylinder cover. When each cylinder cover needs to be rotated to open or close, the user operates the cylinder cover through the handle, which makes the operation more convenient and labor-saving. Preferably, each handle is provided at one end away from the rotation center of the corresponding cylinder cover, for example Figure 1 The lower end is the rotation center position of the first cylinder cover 11 and the second cylinder cover 12, so it is preferred to set the first handle 17 and the second handle 18 at the upper position, that is, above the corresponding cylinder cover. When the user operates the cylinder cover through the handle, there is a larger torque, which is correspondingly more labor-saving.

[0052] It can be seen from the above embodiments that the position of the rotation center is not limited to the form shown in Figure 1 and can be adjusted according to actual conditions. For example, assuming that the rotation center of the second cylinder cover 12 is at the corresponding fixing device 19, the second handle 18 on the second cylinder cover 12 is correspondingly set at a position close to the rotation center of the first cylinder cover 11 to ensure that the user has a longer torque when pulling the handle to achieve a labor-saving effect.

[0053] Furthermore, the anchor chain cylinder cover 10 is provided with a fixing device 19 on each of the first cylinder cover 11 and the second cylinder cover 12. The fixing device 19 connects the first cylinder cover 11 and the second cylinder cover 12 to the hull.

[0054] In this embodiment, the first and second cylinder covers 11, 12 are each provided with a fixing device 19. When the cylinder covers need to remain closed, the first and second cylinder covers 11, 12 are tightened via the fixing device 19, thereby keeping the cylinder covers closed and fixed during the operation of the hull. In this embodiment, each cylinder cover has two fixing points: the rotation center and the location of the fixing device 19. These two locations are used to fix the cylinder cover. Therefore, the rotation center and the fixing device 19 are preferably located at both ends of the corresponding cylinder cover, as far apart as possible.

[0055] like Figure 4 and Figure 5The diagram shows the structure of fixture 19, which includes a threaded hole in the hull, a bolt that passes through the barrel cover, and a screw clip that cooperates with the bolt. Because fixture 19 requires tightening and fixing, the barrel cover at fixture 19 is an extension of the barrel cover body. Fixture 19 is installed by welding extension 191 to the barrel cover body. The thickness of extension 191 is greater than that of the barrel cover body, making fixture 19 stronger and less prone to damage during tightening.

[0056] The anchor chain barrel cover 10 is optional, wherein the first barrel cover 11 and the second barrel cover 12 are located in the same plane and are symmetrically arranged, and the axis of symmetry is the center line of the anchor chain barrel.

[0057] In this embodiment, the first cylinder cover 11 and the second cylinder cover 12 are preferably arranged in a completely symmetrical form, and the handles and reinforcement ribs arranged on the cylinder cover are also symmetrical. This arrangement facilitates the processing and installation of each component. Figure 3 As shown, when the first cylinder cover 11 and the second cylinder cover 12 are fully closed, they are close to each other, or even abut against each other, forming a cylinder cover structure covering the anchor chain cylinder.

[0058] Optionally, the anchor chain cover 10 has an angle between the first reinforcing rib 15, the second reinforcing rib 16 and the symmetry axis of 20°-30°.

[0059] In the above embodiment, the first reinforcing rib 15 and the second reinforcing rib 16 are long strips, and the steps are carried out along the longest direction of the corresponding cylinder cover. Preferably, the angle between each reinforcing rib and the symmetry axis is set to 25°.

[0060] In the optional anchor chain cover 10, the angle between the first handle 17, the second handle 18 and the axis of symmetry is 30°-35°. Figure 1 As shown, the arrangement of the first handle 17 and the second handle 18 meets the requirements of labor saving and usage, and the angle between the handle and the symmetry axis is preferably set to 30°.

[0061] The anchor chain cylinder cover 10 provided in the above embodiment is designed as two semicircular shapes. The top of each cylinder cover is used as a rotation axis, and the cylinder cover is opened by rotation. While ensuring normal opening and closing functions, it can be used in a small space.

[0062] This embodiment further provides a hull, comprising a hawser tube, wherein the hawser tube is arranged at the bow of the hull.

[0063] The upper cover of the anchor chain cylinder is provided with the anchor chain cylinder cover 10 for use in a narrow space.

[0064] The hull provided in this embodiment is provided with a chain pipe at the bow, which is used to accommodate the anchor chain. Since the position of the bow of the hull may be relatively small, the chain pipe cover 10 provided in the above embodiment is covered on the chain pipe. The chain pipe cover 10 is composed of two parts, and the two parts of the cylinder cover can rotate around the corresponding rotation center. Preferably, in this embodiment, the rotation centers of the two cylinder covers are arranged side by side. The two cylinder covers are rotated away from each other to open the chain pipe cover 10, and are rotated close to each other to close the chain pipe cover 10. The function of the chain pipe cover 10 can be realized in the smaller space of the bow of the hull. When the two parts of the chain pipe cover 10 are closed, the chain pipe cover 10 is fixed to the hull by the fixing device 19, thereby fixing the chain pipe cover 10.

[0065] The anchor chain cylinder cover 10 provided in this embodiment is further provided with a corresponding opening, through which the anchor chain passes through the anchor chain cylinder cover 10 , and the cylinder cover does not affect the position of the anchor chain. The shape and size of the opening are determined according to the structure of the anchor chain, so that the anchor chain cylinder cover 10 is more in line with usage requirements.
