Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a limiting device for ships and marine storage tanks. Background Technology

[0002] Currently, an increasing number of ships are no longer using single fossil fuels, and the proportion of dual-fuel vessels is constantly rising. In these dual-fuel vessels, the fuel storage system is a crucial aspect of ship design. According to the International Maritime Organization's classification, the most widely used fuel storage systems currently include independent Type A, B, and C tanks and membrane-type systems. Independent Type A, B, and C tanks can be constructed separately and then hoisted into the ship's hull as a whole. The tank and the hull are constrained and load-transferred through various support and limiting devices. For independent tanks, the design of the support and limiting devices is extremely important, as it relates to the tank's operational safety. With the increasing volume of the tanks, the requirements for the limiting devices are also becoming more stringent. Therefore, there is an urgent need to provide a high-strength limiting device.

[0025] The fastener includes reinforcing ribs that are arranged on opposite sides of the fixing plate. The reinforcing ribs are inclined from top to bottom toward the other fixing plate. There is a gap between the top of the reinforcing rib and the top wall of the hull, and the bottom of the reinforcing rib is close to the top of the fixing block.

[0035] The limiting device and the saddle are separate, allowing the limiting device to only provide longitudinal or lateral restraint without bearing the weight of the tank. The saddle at the bottom primarily supports the tank, significantly improving the structure of the tank bottom and the stress distribution on the saddle, thus enhancing the overall safety of the tank. This limiting device has a simple structure and can be manufactured and installed independently. Attached Figure Description

[0043] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0044] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0045] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0046] It should be noted that in current independent C-type storage tanks, a typical support system usually includes two saddles, one lateral limiting device, and one longitudinal limiting device. The two saddles are one fixed saddle and one sliding saddle. Both the lateral and longitudinal limiting devices are integrated with the fixed saddle.

[0047] Two grooves are made in the wooden block for fixing the saddle. Steel plates are used for the lateral and longitudinal limiting devices, which are inserted into the grooves to embed them into the wooden block, and then filled with epoxy resin. This solution is simple, but because the wooden blocks need to be customized and have irregular cross-sections, the grooves significantly affect the strength of the blocks. When a ship is moving at sea, the storage tank will sway with the ship due to acceleration in all directions and wave impact. The above support method places high demands on the strength of the wooden block and the embedded steel plates, and there is a certain risk of fatigue. Therefore, the steel plates need to be relatively thick, typically reaching 40mm. At the same time, the grooves in the wooden blocks also pose a risk of tearing. Especially when the storage tank is large, the inertial forces in both directions are greater, and the strength requirements for the limiting devices are even higher.

[0048] Therefore, this application provides a novel limiting device for marine storage tanks, which is independent of the saddle and has high strength.

[0049] Combination Figures 1-4The limiting device 1 of the marine storage tank 3 in this application includes two fixing members and a limiting member. The fixing members are fixed to the bottom of the top wall 21 of the hull 2, and the limiting member is fixed to the storage tank 3. The fixing members include two fixing blocks 112 spaced apart, and the limiting member includes a limiting block 122 located between the two fixing blocks 112. The two limiting blocks 122 are respectively provided corresponding to the two fixing blocks 112, and the limiting block 122 can abut against the corresponding fixing block 112 to restrict the movement of the storage tank 3.

[0050] In this application, the storage tank 3 is installed on the hull 2 ​​in a horizontally extending manner. For ease of description, the axis of the storage tank 3 is defined as longitudinal, and the direction perpendicular to the axis in the horizontal direction is defined as transverse.

[0051] Combination Figure 1 and Figure 2 The limiting device 1 includes two fixing members spaced apart. The two fixing members are spaced apart along a first direction. The first direction can be the longitudinal direction of the storage tank 3 or the transverse direction of the storage tank 3.

[0052] Specifically, the fasteners include a fixing plate 111 fixed to the bottom of the top wall 21 of the hull 2 ​​and a fixing block 112 fixed to the inner side of the fixing plate 111. Here, "inner" and "outer" are used with reference to the operating state of the limiting device 1, with the direction towards the space between the two fasteners being "inner" and the opposite being "outer".

[0053] The top of the fixing plate 111 is fixedly connected to the top wall 21 of the hull 2. In this embodiment, the fixing plate 111 is welded to the bottom of the top wall 21 of the hull 2.

[0054] The outer side of the fixing plate 111 is inclined from top to bottom towards the other fixing plate 111 to form an inclined surface.

[0055] The inner side of the lower part of the fixing plate 111 is recessed outward to form a recessed space. Specifically, the inner side of the fixing plate 111 includes a first plane extending vertically, a second plane bending horizontally inward from the first plane, a third plane bending downward from the second plane and extending downward, and a transition surface that is arc-shaped and connects the second plane and the third plane. The second plane, the transition surface and the third plane enclose the recessed space.

[0056] That is, the fixing plate 111 includes a connecting surface that fits into the bottom of the top wall 21 of the hull 2, an inclined surface located outside the connecting surface, a first plane located inside the connecting surface, and a second plane, a transition surface and a third plane.

[0057] The fastener includes a support plate 113 correspondingly disposed inside the fixing plate 111, the support plate 113 having a support surface extending vertically. Specifically, the support plate 113 is in contact with the second plane, the third plane, and the fourth plane. The portion of the support plate 113 in contact with the fourth plane constitutes the support surface.

[0058] The support plate 113 preferably extends downward beyond the fixing plate 111.

[0059] A fixing block 112 is disposed on the supporting surface. The fixing block 112 is bonded to the supporting plate 113. The fixing block 112 is made of wood. In this embodiment, the fixing block 112 is made of laminated wood. In other embodiments, the fixing block 112 may also be made of other types of wood with low-temperature resistance and high strength. The fixing block 112 and the supporting plate 113 are bonded together with epoxy putty.

[0060] The space between the fixing blocks 112 of the two fixing members forms an accommodating space.

[0061] The fixing block 112 is square in shape. Along the vertical direction, the supporting plate 113 extends downward beyond the fixing block 112. The bottom of the fixing plate 111 extends downward beyond the fixing block 112 or the bottom of the fixing plate 111 is flush with the bottom of the fixing block 112.

[0062] Preferably, the fastener includes two positioning plates 114 fixed vertically at intervals to the inner side of the support plate 113, the distance between the two positioning plates 114 being greater than the height of the fixing block 112. The positioning plates 114 are used to prevent adhesive from overflowing when the fixing block 112 and the support plate 113 are bonded together.

[0063] The fastener includes a base plate 115 correspondingly disposed at the bottom of the inclined surface. A gap exists between the top of the base plate 115 and the top wall 21 of the hull 2, thus isolating the base plate 115 from the top wall 21 of the hull 2 ​​and preventing the load on the base plate 115 from being directly transmitted to the top wall 21 of the hull 2. The base plate 115 is used to prevent deformation of the fixing plate 111.

[0064] The bottom of the base plate 115 is also fixedly connected to the support plate 113. The bottom of the support plate 113 extends downward beyond the base plate 115.

[0065] The width of the base plate 115 gradually increases from top to bottom. In this embodiment, the cross-section of the base plate 115 is triangular. This triangle is isosceles and symmetrical about the fixing plate 111.

[0066] The base plate 115 extends outward beyond the opposite sides of the fixing plate 111, specifically meaning that the base plate 115 extends outward beyond the fixing plate 111 in a direction perpendicular to the base plate 115. The larger area of ​​the base plate 115 increases the strength of the entire fastener.

[0067] The fastener includes reinforcing ribs 116 arranged on opposite sides of the fixing plate 111. That is, the fastener includes four reinforcing ribs 116, with two reinforcing ribs 116 corresponding to one fixing plate 111. The function of the reinforcing elbow plate 119 is to prevent deformation of the fixing plate 111 and increase the strength of the entire fastener.

[0068] The reinforcing rib 116 is inclined from top to bottom toward the other fixed plate 111. This inclination allows the load on the reinforcing rib 116 to be distributed into loads in two directions.

[0069] There is a gap between the top of the reinforcing rib 116 and the top wall 21 of the hull 2. The bottom of the reinforcing rib 116 is close to the top of the fixing block 112. This design not only isolates the load transfer between the reinforcing rib 116 and the top wall 21 of the hull 2, but also increases the connection strength between the fixing block 112 and the fixing plate 111.

[0070] The reinforcing rib 116 is connected to the support plate 113. In this embodiment, the connection points of the reinforcing rib 116 and the support plate 113, as well as the connection points of the fixing block 112 and the support plate 113, are located on opposite sides of the support plate 113, and the two connection points are relatively close to each other.

[0071] The reinforcing rib 116 has an inclined surface on its outer side away from the fixing plate 111, and this inclined surface is located on the upper part of the reinforcing rib 116. The inclined surface is inclined from top to bottom in a direction away from the fixing plate 111.

[0072] A web plate 117 is preferably provided between the base plate 115 and the reinforcing rib 116. The top of the web plate 117 is attached to the bottom of the reinforcing rib 116, and the bottom of the web plate 117 is attached to the top of the base plate 115. The web plate 117 is arranged parallel to and spaced apart from the fixing plate 111, and the web plate 117 is fixedly connected to the support plate 113. Through the connection of the web plate 117, the base plate 115, the reinforcing rib 116, and the support plate 113 are interconnected, further increasing the connection strength of the fasteners.

[0073] The middle part of the side of the web plate 117 facing away from the fixing block 112 is recessed inward. This design increases the contact area between the web plate 117 and the bottom plate 115, as well as between the web plate 117 and the top plate, thereby increasing the connection strength.

[0074] The fastener includes a stiffening plate 118 disposed inside the fixing plate 111. The top of the stiffening plate 118 is connected to the top wall 21 of the hull 2, and the stiffening plate 118 extends in a direction perpendicular to the two fixing plates 111, that is, the stiffening plate 118 extends in a second direction. Both ends of the stiffening plate 118 extend outward to cover the fixing block 112.

[0075] The stiffening rib 118 corresponds to the first plane of the fixing member. In this embodiment, the height of the stiffening rib 118 is the same as the height of the first plane. The stiffening rib 118 is spaced above the fixing block 112.

[0076] An elbow plate 119 is provided on the inner side of the stiffening rib 118. The elbow plate 119 is provided corresponding to the fixing plate 111, which can be understood as the elbow plate 119 and the fixing plate 111 being arranged on opposite sides of the stiffening rib 118 along the first direction. The elbow plate 119 is preferably located on the same straight line as the fixing plate 111.

[0077] In this embodiment, the elbow plate 119 has a triangular cross-section. One side of the elbow plate 119 is attached to the stiffening plate 118, the other side is attached to the top wall 21 of the hull 2, and the remaining side is inclined.

[0078] The fixing plate 111, through the setting of the base plate 115 and the reinforcing elbow plate 119, increases the section modulus of the entire fixing member, significantly improving the structural strength of the entire fixing member. Furthermore, the structural strength is further improved through the setting of the web plate 117, the stiffening plate 118, and the elbow plate 119.

[0079] The limiting component includes a connector fixed to the top of the storage tank 3 and limiting blocks 122 arranged at opposite ends of the connector. The limiting blocks 122 are located within the accommodating space. The two limiting blocks 122 are respectively provided corresponding to the two fixed blocks 112, and the limiting blocks 122 can abut against the corresponding fixed blocks 112 to restrict the movement of the storage tank 3.

[0080] The connector includes a connecting plate 1211 erected on the top of the storage tank 3 and side plates 1212 arranged at opposite ends of the connecting plate 1211. The bottom of the connecting plate 1211 and the two side plates 1212 are adapted to the top of the storage tank 3 and connected to the top of the storage tank 3.

[0081] The connecting plate 1211 extends along the direction in which the two fixed plates 111 are set, that is, the connecting plate 1211 extends along the first direction. The bottom shape of the connecting plate 1211 is adapted to the structure of the connection between the top of the storage tank 3 and the connecting plate 1211.

[0082] Side plate 1212 is perpendicular to connecting plate 1211, that is, side plate 1212 extends along the second direction. The bottom shape of side plate 1212 is adapted to the structure at the connection between the top of tank 3 and side plate 1212. Side plate 1212 extends upward beyond connecting plate 1211.

[0083] The connector also includes a top panel 1213 disposed on the top of the connecting plate 1211. The top panel 1213 is connected to the two side panels 1212. That is, the bottom of the top panel 1213 is fixedly connected to the connecting plate 1211, and the two ends of the top panel 1213 along the first direction are fixedly connected to the inner side of the side panel 1212.

[0084] The connector also includes a lower panel 1214 disposed below the connecting plate 1211. The two ends of the lower panel 1214 are respectively connected to the two side panels 1212. The lower panel 1214 is located below the upper panel 1213 at a parallel interval. The lower panel 1214 is located above the storage tank 3 at a distance.

[0085] Specifically, the lower panel 1214 includes two plates, which are arranged on opposite sides of the connecting plate 1211 along the second direction.

[0086] The connection strength between the connecting plate 1211 and the side plate 1212 is increased by the upper panel 1213 and the lower panel 1214, thereby increasing the strength of the connector.

[0087] The connector also includes a reinforcing plate 1215 correspondingly disposed inside the side plate 1212. The reinforcing plate 1215 is disposed between the upper panel 1213 and the lower panel 1214. The reinforcing plate 1215 is disposed parallel to and spaced apart from the connecting plate 1211. Reinforcing plates 1215 are provided on both opposite sides of the connecting plate 1211. The reinforcing plates 1215 further increase the connection strength of the connector.

[0088] In this embodiment, there are four reinforcing plates 1215, with each side plate 1212 corresponding to two reinforcing plates 1215. The two reinforcing plates 1215 corresponding to each side plate 1212 are arranged on opposite sides of the connecting plate 1211 along the second direction.

[0089] The limiting block 122 is disposed on the outer side of the side plate 1212. The limiting block 122 is made of wood. In this embodiment, the limiting block 122 is made of laminated wood.

[0090] The limiting block 122 is bonded to the side plate 1212. In this embodiment, the two are bonded together with epoxy putty.

[0091] The limiting member preferably includes two baffles 1216 fixed vertically at intervals to the outer side of the side plate 1212, the distance between the two baffles 1216 being greater than the height of the limiting block 122. The baffles 1216 are used to prevent the overflow of adhesive when the limiting block 122 is bonded to the side plate 1212.

[0092] The limiting block 122 can abut against the corresponding fixing block 112 to limit the movement of the storage tank 3, prevent the storage tank 3 from shaking, and ensure the safety of the storage tank 3.

[0093] Preferably, there is a gap between the limiting block 122 and the fixing block 112. Specifically, when the two limiting blocks 122 are symmetrically distributed in the accommodating space, the gap between each limiting block 122 and the corresponding fixing block 112 is 3mm.

[0094] The material of the connector is the same as the material of the part of the storage tank 3 to which it is connected. That is, the connector is connected to the top of the storage tank 3, therefore, the material of the connector and the top of the storage tank 3 is the same. For example, if the storage tank 3 is made of a low-temperature resistant material, then the connector is also made of low-temperature resistant steel.

[0095] In the fasteners, except for the fastening block 112, all other structures can be made of high-strength metal materials, and there are no restrictions on their low-temperature resistance.

[0096] In summary, the limiting device 1 has the following advantages:

[0097] 1. The limiting device 1 is independent of the saddle at the bottom of the storage tank 3, and has a simple structure, allowing for independent fabrication and installation. Because the limiting device 1 is separate from the saddle, it maintains the integrity of the wooden block of the bottom saddle, avoiding the risk of tearing the bottom wooden block and epoxy resin.

[0098] 2. By separating the limiting device 1 from the saddle, the limiting device 1 only undertakes longitudinal or lateral limiting and does not bear the weight of the storage tank 3, while the bottom saddle is mainly used to support the storage tank 3. This significantly improves the structure of the bottom of the storage tank 3 and the stress situation of the saddle, making the entire storage tank 3 safer.

[0099] 3. The limiting device 1, through the design of the fixing and limiting components, has high structural strength and flexibility, and is suitable for various types (such as single tanks, double tanks, etc.) and sizes of marine C-type storage tanks 3, with a wide range of applications.

[0100] The storage tank 3 in this embodiment is a single-lobed C-shaped structure. When the storage tank 3 is a double-lobed structure, the limiting device 1 can be set at the connection of the two lobes. At this time, the shape of the connector is adapted to the shape of the connection.

[0101] This utility model also provides a ship, including a hull 2, a storage tank 3 disposed on the hull 2, and the aforementioned limiting device 1.

[0102] Storage tank 3 is located in a compartment of hull 2. One storage tank 3 or multiple storage tanks 3 can be installed in one compartment; there is no limit to the number of storage tanks 3.

[0103] Taking a single storage tank 3 as an example, the number of limiting devices 1 is at least three, of which at least two are spaced apart at both ends along the axial direction of the storage tank 3 to restrict the storage tank 3 from moving laterally, and at least one is located in the middle of the storage tank 3 to restrict the storage tank 3 from moving axially.

[0104] The connecting plate 1211 and the reinforcing structure inside the storage tank 3 are located on the same plane.

[0105] By setting the aforementioned limiting device 1, the impact of the forward and backward, left and right swaying of the storage tank 3 on the strength of the hull 2 ​​and the storage tank 3 itself is effectively reduced, thus improving safety.

[0106] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
