[0003] In the process of transporting corrugated oil tanks, in order to prevent the corrugated oil tanks from being impacted and vibrated, additional protection will be provided for the corrugated oil tanks. For corrugated oil tanks with a capacity of less than 6000kVA, the existing method of wrapping the corrugated oil tanks with reinforced round steel, detachable reinforcement plates with shock-absorbing rubber and other components are installed at the bottom of the corrugated sheet to prevent the pressure and vibration at the bottom of the corrugated sheet from causing cracking and oil leakage of the corrugated sheet. However, the above reinforcement method is only applicable to corrugated oil tanks with a capacity of less than 6000kVA, while corrugated oil tank products with a capacity of more than 6000kVA have larger sizes and heavier weights than ordinary corrugated oil tanks. For corrugated oil tanks with a capacity of more than 6000kVA, the reinforcement effect of the above reinforcement method is poor and is not suitable for the transportation of large corrugated oil tank products.

[0032] The utility model provides a large corrugated oil tank with a reinforced transportation structure.

[0033] In the embodiment of the present utility model, Figures 1 to 3As shown, a large corrugated oil tank with a reinforced transport structure includes an oil tank body 1 and at least two sets of fastening components 2, the fastening components 2 include four pressing members 21, four connecting members 22 and four sealing pads 23, the pressing member 21 includes a channel steel 211 and a mounting plate 212, the two ends of the channel steel 211 along the length direction are respectively connected with the mounting plates 212, and the mounting plates 212 are provided with mounting holes 2121;

[0034] In the same fastening assembly 2, between two adjacent clamping members 21, the connecting member 22 passes through the mounting hole 2121 of one mounting plate 212 and then passes through the mounting hole 2121 of another mounting plate 212, and the four clamping members 21 are connected end to end in sequence through a plurality of connecting members 22 to form a rectangle;

[0035] The sealing gasket 23 is pressed between the outer wall surface of the oil tank body 1 and the inner wall surface of the channel steel 211;

[0036] The two sets of fastening components 2 are arranged on the fuel tank body 1 at intervals along the height direction of the fuel tank body 1 .

[0037] It can be understood that by setting at least two sets of fastening components 2, the fastening components 2 include four clamping members 21, four connecting members 22 and four sealing pads 23, the clamping members 21 include channel steels 211 and mounting plates 212, each channel steel 211 is respectively connected to mounting plates 212 at both ends along the length direction, in the same fastening component 2, two adjacent clamping members 21 are connected by connecting members 22, and the mounting plates 212 are in the same fastening component 2, and the four clamping members 21 are connected end to end by multiple connecting members 22 in sequence to form a rectangle, so as to surround the fuel tank body 1. The sealing gasket 23 is pressed between the outer wall of the oil tank body 1 and the inner wall of the channel steel 211. The gap between the oil tank body 1 and the pressing piece 21 is filled with the sealing gasket 23. The sealing gasket 23 tightly wraps the oil tank body 1 under the action of the pressing piece 21, and compresses the corrugated sheet of the oil tank body 1, which can further suppress the vibration of the corrugated sheet, ensure the structural stability of the large corrugated oil tank during transportation, and avoid the local fracture of the corrugated sheet. In addition, it can avoid the situation that part of the corrugated sheet is fixed and part of the corrugated sheet is not fixed due to processing deviation.

The utility model is suitable for corrugated oil tanks with a capacity of more than 6000kVA, and can effectively compress the corrugated sheet of the large corrugated oil tank, suppress the vibration of the corrugated sheet during transportation, and improve the strength of the overall structure. It solves the technical problem that the existing corrugated oil tank reinforcement structure has poor reinforcement effect and is not suitable for the transportation of large corrugated oil tank products. After transportation is completed, the connection member 22 is disassembled, and then the pressing member 21 is disassembled, so as to avoid affecting the heat dissipation effect of the corrugated sheet.

[0038] See also Figure 4In one embodiment of the present application, the channel steel 211 includes a first transverse plate 2111, a second transverse plate 2112 and a vertical plate 2113, one end of the vertical plate 2113 is connected to the first transverse plate 2111, and the other end of the vertical plate 2113 is connected to the second transverse plate 2112, the first transverse plate 2111 and the second transverse plate 2112 are arranged in the horizontal direction, and the vertical plate 2113 is arranged in the vertical direction;

[0039] The mounting plate 212 is connected between the first transverse plate 2111 and the second transverse plate 2112 , and the mounting plate 212 is connected to both ends of the first transverse plate 2111 in the length direction;

[0040] The first transverse plate 2111 , the second transverse plate 2112 , the vertical plate 2113 and the mounting plate 212 together form a mounting groove 2114 .

[0041] The channel steel 211 of the utility model includes a first horizontal plate 2111, a second horizontal plate 2112 and a vertical plate 2113, which are combined with the mounting plate 212 to form a mounting groove 2114, which meets the high strength requirement, avoids the deformation of the corrugated sheet due to uneven force, and reduces the weight, thereby reducing the transportation and installation costs. In addition, the mounting groove 2114 formed by the enclosure provides a large space for assembling the two pressing members 21.

[0042] See also Figure 4 In one embodiment of the present application, the first horizontal plate 2111 and the second horizontal plate 2112 are respectively trapezoidal in shape.

[0043] The first transverse plate 2111 and the second transverse plate 2112 are in a trapezoidal shape, which can better disperse stress when the channel steel 211 is subjected to vertical or horizontal forces, maintain good shape stability, avoid excessive deformation or damage, and thus improve its load-bearing performance. In addition, the trapezoidal shape of the first transverse plate 2111 and the second transverse plate 2112 makes the channel steel 211 more stable during placement and installation, and is not prone to tilting or rolling, further ensuring the stability of the overall structure.

[0044] See also Figure 2 and 4 In one embodiment of the present application, the mounting hole 2121 is disposed at the center of the mounting plate 212 .

[0045] By arranging the mounting hole 2121 in the center of the mounting plate 212, during the assembly process, the mounting holes 2121 of the two mounting plates 212 can be accurately aligned, thereby improving the assembly efficiency.

[0046] See also Figure 2 In one embodiment of the present application, the connecting member 22 includes a bolt 221 and a nut 222;

[0047] Between two adjacent clamping members 21 in the same fastening assembly 2 , a bolt 221 passes through a mounting hole 2121 of one mounting plate 212 and a mounting hole 2121 of another mounting plate 212 in sequence, and the bolt 221 passes through the mounting hole 2121 of the other mounting plate 212 and is connected with a nut 222 .

[0048] The connecting member 22 adopts a threaded engagement connection method, which has a reliable fastening force, ensuring a stable connection between two adjacent pressing members 21 in the same fastening assembly 2. In the event of vibration, impact, etc. during transportation, the bolt 221 and the nut 222 can still maintain a good fastening state and are not easy to loosen or fall off. In addition, the threaded engagement connection method has the advantages of easy installation, disassembly and maintenance. After the transportation reaches the destination, the fastening assembly 2 of the utility model can be removed in time to avoid affecting the heat dissipation effect of the corrugated sheet and the normal use of the subsequent large corrugated oil tank.

[0049] See also Figure 2 In one embodiment of the present application, the connecting member 22 further includes a gasket 223 , a gasket 223 is provided between the bolt 221 and the corresponding mounting plate 212 , and a gasket 223 is provided between the nut 222 and the corresponding mounting plate 212 .

[0050] By providing a gasket 223 between the bolt 221 and the corresponding mounting plate 212, and by providing a gasket 223 between the nut 222 and the corresponding mounting plate 212, the contact area between the bolt 221 and the corresponding mounting plate 212, and between the nut 222 and the corresponding mounting plate 212 can be increased, and the firmness and stability of the connection can be further improved. In addition, since the gasket 223 has a certain elasticity and thickness, it can effectively protect the surface of the bolt 221, the nut 222 and the mounting plate 212, and prevent scratches and wear caused by direct contact between the parts; the gasket 223 can also provide a certain pre-tightening force to prevent the bolt 221 and the nut 222 from loosening with the mounting plate 212 under the action of external force.

[0051] See also Figure 2 In one embodiment of the present application, an installation gap 24 is formed between two adjacent installation plates 212 .

[0052] An installation gap 24 is formed between two adjacent mounting plates 212, which can further more effectively compress the corrugated sheets of the corrugated oil tank, and is suitable for large corrugated oil tanks. During the installation process, the two adjacent pressing members 21 first press the sealing gasket 23 onto the outer wall of the oil tank body 1, and then the connecting member 22 is passed through the mounting holes 2121 of the two mounting plates 212 in sequence. After the fastening assembly 2 and the oil tank body 1 are installed, there is an installation gap 24 between two adjacent mounting plates 212 in the same fastening assembly 2, which can compress all the corrugated sheets.

[0053] See also Figure 1 and 2 In one embodiment of the present application, the thickness of the mounting plate 212 is 8 mm to 10 mm.

[0054] The mounting plate 212 forms the connection surface between adjacent pressing members 21 in the same set of fastening components 2. The mounting plate 212 with a suitable thickness can ensure a more stable connection between the pressing members 21. If the mounting plate 212 is thin, it cannot meet the connection strength requirement. The mounting plate 212 with a suitable thickness can also disperse local stress and protect the mounting plate 212 itself and the connecting member 22 from damage.

[0055] Preferably, the thickness of the mounting plate 212 is 8 mm.

[0056] See also Figure 1 and 3 In one embodiment of the present application, the thickness of the sealing gasket 23 is 10 mm to 13 mm.

[0057] Based on factors such as size matching, performance requirements, material selection, and comprehensive cost considerations, a sealing gasket 23 of a certain thickness can ensure that the corrugated oil tank has good sealing performance while meeting actual usage requirements.

[0058] Preferably, the sealing pad 23 has a thickness of 12 mm.

[0059] In one embodiment of the present application, the outer surfaces of the channel steel 211 and the mounting plate 212 are both provided with a polyurethane coating.

[0060] The polyurethane coating forms an effective protective layer on the outer surface of the channel steel 211 and the mounting plate 212, which can effectively protect the channel steel 211 and the mounting plate 212 from corrosion and rust, and at the same time make the channel steel 211 and the mounting plate 212 have good weather resistance, wear resistance and chemical corrosion resistance, thereby improving the service life and appearance of the channel steel 211 and the mounting plate 212.

[0061] Specifically, the channel steel 211 is a 8# channel steel of Q235B.

[0062] The channel steel 211 is made of 8# channel steel of Q235B, which has high tensile strength and can withstand large external forces without obvious plastic deformation. In addition, the channel steel 211 also has good welding performance and processability. It can meet different engineering requirements through various processing methods such as cutting, welding, and punching, which is convenient for construction and installation, and then convenient for connecting and assembling the channel steel 211 with other components, that is, it is conducive to welding the mounting plate 212 on the side of the channel steel 211. Preferably, the channel steel 211 and the mounting plate 212 are welded by full welding. In addition, the channel steel 211 is made of 8# channel steel of Q235B, which has good plasticity and toughness and can withstand certain impact loads.

[0063] To further explain, the material of the sealing pad 23 is acrylic rubber or cork rubber.

[0064] Acrylic rubber has excellent weather resistance such as resistance to sunlight aging and temperature changes, high mechanical properties, and high chemical stability and thermal stability. Acrylic rubber is used as the material of the sealing gasket 23, which ensures that the large corrugated oil tank is tightly wrapped while having high comprehensive performance. Cork rubber is a lightweight material, which can make the sealing gasket 23 made of cork rubber more convenient during installation and use. When cork rubber is used as the material of the sealing gasket 23, the sealing gasket 23 can have good elasticity and maintain stable sealing performance even when subjected to pressure or temperature changes.

[0065] Preferably, the Shore hardness of the acrylic rubber is 60 degrees.

[0066] For the sealing gasket 23, appropriate hardness can ensure that it can not only fit the sealing surface tightly, but also has a certain elasticity to adapt to the slight deformation of the sealing surface. Acrylic rubber with a Shore hardness of 60 degrees is used as the material of the sealing gasket 23. At this time, the sealing gasket 23 made has a certain durability and aging resistance, and maintains good elasticity and plasticity. Cork rubber, as a lightweight material, can make the sealing gasket 23 made of cork rubber more convenient during installation and use. When cork rubber is used as the material of the sealing gasket 23, the sealing gasket 23 can have good elasticity and maintain stable sealing performance even when subjected to pressure or temperature changes.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
