Description

Technical Field

[0001] The utility model relates to the technical field of generator installation structures, in particular to a replaceable generator and base installation structure for ships. Background Art

[0002] During its service, the intelligent technology test vessel has the ability to conduct on-board testing projects with new marine generators. However, for replacing different generators, the traditional method requires first docking the ship at a dock with a large crane, and then cutting and replacing the original fixed generator base. If the installation width of the new machine is different from the previous machine, it may also be necessary to cut the inner bottom plate, rebuild the support structure inside the hull, and finally repaint. The project is huge and time-consuming. Not only are the material costs high, but the dock fees and labor costs of docking are also considerable expenses. Therefore, there is an urgent need to invent a replaceable generator structure base. Similarly, operating ships will also have such problems. If the shipowner needs to update or replace the generator on board, the old base may not be able to adapt to the new unit. This multi-functional structural base is also in demand.

[0003] Typically, the foundations are custom-made. Since the width of the base of the same generator is fixed, the spacing between the two foundations underneath is also essentially fixed, meaning one generator corresponds to one fixed foundation. Furthermore, longitudinal support structures are required within the hull to align with the longitudinal plates of the foundations to ensure overall strength and rigidity. Therefore, the support structures within the hull are also fixed.

[0004] When it is necessary to replace a different type of generator, such as Figure 1 As shown, the traditional construction method is as follows:

[0005] First, loosen the bolts and lift the generator from the elastic base;

[0006] Cut off the original fixed base;

[0007] The inner bottom plate is partially cut open, and most of the supporting structure 1 under the original base is cut away.

[0008] Then, a new support structure is repaired to the cut part and covered with a partial inner bottom plate;

[0009] Weld the new fixing base into place,

[0010] Then hoist in the replaced elastic base and new generator and tighten the bolts.

[0011] Since cutting and welding will damage the paint, the paint in the relevant locations must be repaired after installation is completed.

[0012] Therefore, traditional generator replacement technology has the following disadvantages:

[0013] 1) When a generator needs to be replaced, the associated base and supporting structure become consumables. Each time a new generator model is changed, the base and supporting structure need to be replaced, consuming a large amount of material and requiring repainting of the affected parts. The entire project requires the use of a large number of professionals and specialized equipment, which is not only costly but also time-consuming.

[0014] 2) When replacing the generator, the ship must dock at a dock with a large crane. If the construction time is long, the dock fee will also be a considerable expense.

[0015] 3) Testing different generators on a real ship is only part of the ship's capabilities. When the replacement work is in progress, the ship is basically unable to carry out other test work, affecting the shipowner's other work arrangements.

[0016] In summary, using traditional technology to replace generators requires a lot of work, costs a lot of money, and takes a long time, which is very inconvenient for ship owners. Utility Model Content

[0021] A generator fixing base, having a single row of mounting holes or a double row of mounting holes on its bottom, and being detachably connected to the left mounting surface, the right mounting surface, or both of the left and right mounting surfaces of the fixing base by fasteners;

[0022] an adjusting gasket installed between the fixing base and the generator fixing base; and

[0023] The generator elastic base is detachably connected to the generator fixed base via fasteners.

[0057] In this embodiment, the upper panel 41 is provided with a base mounting hole (not shown) for connecting to the generator elastic base 5 .

[0058] In this embodiment, the lower panel 42 is provided with a single row of mounting holes 45 or a double row of mounting holes 46 .

[0059] In this embodiment, the single row of mounting holes 45 is used to connect the generator fixing base 4 to the left mounting surface 24 or the right mounting surface 25 of the fixing base 2 .

[0060] In this embodiment, the double-row mounting holes 46 are used to simultaneously connect the generator fixing base 4 to the left mounting surface 24 and the right mounting surface 25 of the fixing base 2 .

[0061] In this embodiment, as Figure 7 and Figure 9 shown, the adjusting gasket 3 is provided with a single-hole round hole 31 or a double-hole round hole 32 whose position corresponds to the position of the single-row mounting hole 45 or the double-row mounting hole 46.

[0062] In this embodiment, the left mounting surface 24 and the right mounting surface 25 of the fixed base 2 are each provided with a connecting hole 251 whose direction is perpendicular to the position of the single-row mounting hole 45 and / or the double-row mounting hole 46; the fastener 6 passes through the single-row mounting hole 45 or the double-row mounting hole 46, the single-hole round hole 31 or the double-hole round hole 32 and the connecting hole 251 to connect the fixed base 2, the adjusting gasket 3 and the generator fixed base 4.

[0063] In this embodiment, as Figure 3 shown, the hull support structure 1 includes a hull bottom plate 11, hull support columns 12 vertically supported at the bottom of the hull bottom plate 11, and a hull reinforcing plate 13 connected between the bottom plate 11 and the hull support columns 12.

[0064] In this embodiment, the fixed base 2 includes a base panel 21, base vertical plates 22 vertically supported at the bottom of the base panel 21, and a base reinforcing plate 23 connected between the base panel 21 and the base vertical plates 22.

[0065] The characteristics and functions of the present utility model are further understood through the following description.

[0066] As Figure 3 shown, it is a schematic diagram of the maximum installation distance between the generator elastic bases 5, Figure 4 is a schematic diagram of the center installation distance between the generator elastic bases 5, Figure 5 is a schematic diagram of the minimum installation distance between the generator elastic bases 5, Figure 6 is a side view in the hull length direction after the generator is installed.

[0067] The cross-section of the generator fixed base 4 in this embodiment is a "C"-shaped structure: including an upper panel for cooperating with the installation of the elastic base; a lower panel using a longitudinal waist-shaped round hole (i.e., the single-row mounting hole 45 or the double-row mounting hole 46, in a waist-shaped hole structure) for cooperating with the installation of a fixed transverse waist-shaped round hole (i.e., the connecting hole 251, also in a waist-shaped hole structure); a vertical plate connecting the upper panel and the lower panel; and a transverse elbow plate to ensure the overall strength.

[0068] For the installation of the multi-functional generator structure base, the fixed base and the generator, please refer to Figures 3-5A cross-sectional view of the structure is shown. The generator is placed above and connected to the generator elastic base 5. Further down, the generator elastic base 5 is connected to the generator fixed base 4 using bolts (i.e., fasteners 6, which can also be other connection tools or parts). Further down, an adjustment gasket 3 is provided between the generator fixed base 4 and the fixed base 2, which are connected via bolts (i.e., fasteners 6, which can also be other connection tools or parts). Further down, the fixed base 2 is securely welded to the hull support structure 1.

[0069] It can be seen that the fixed base 2 and the hull support structure 1 are solid, and the width of the generator foot is divided into A layout (such as Figure 3 As shown, the foot positioning width is larger), B arrangement (such as Figure 4 As shown, the foot positioning width is moderate), C arrangement (such as Figure 5 As shown, the foot positioning width is smaller) three cases are used to correspond to generators with different foot widths. For the side view of the installation, please see Figure 6 , it can be seen that the generator positioning can also be adjusted in the direction of the ship's length. Figures 7 to 10 shown.

[0070] Compared to traditional methods, each time a generator is replaced, only the holes need to be re-drilled at the appropriate location on the upper panel of the generator mounting base 4. The hull support structure 1, mounting base 2, and adjustment shims 3 remain unchanged. This allows for adaptability to varying footing widths and allows for adjustment along the length of the ship. This entire process not only reduces engineering costs but also minimizes modification time without impacting other ship functions, achieving multiple goals at once.

[0071] The upper panel of the generator fixed base 4 of this embodiment adopts a thicker steel plate, which is in conjunction with the installation of the elastic base. It is a conventional design form and will not be described in detail. The lower panel and the fixed base 2 form cross-shaped bolt holes, supplemented by adjustment gaskets 3, to form a very strong connection form. The vertical plates and horizontal elbow plates ensure the overall strength. Usually, the generator only considers its own weight and the unbalanced bending moment in the direction of the ship width. The overall rigidity of the generator fixed base 4 is very large, and it can form an effective support combination with the fixed base 2 to jointly resist external loads.

[0072] In summary, the replaceable generator and base mounting structure of the present invention has a manageable overall workload, low material consumption, and significant cost savings. The multifunctional base structure can accommodate multiple generator modifications. This significantly reduces operation time, minimizing labor costs and terminal fees. Furthermore, since the inner bottom plate does not need to be cut, the operation process is extremely simple, improving personnel safety. Furthermore, the multifunctional base structure can be hoisted into place after dock construction is completed, eliminating the need for open flames in the ship's hold and enabling purely mechanical installation, thus ensuring vessel safety.
