Description

Technical Field

[0001] This utility model relates to the field of storage tank equipment technology, and in particular to a wind-resistant ring structure for a storage tank. Background Technology

[0002] Enameled prefabricated storage tanks are corrosion-resistant and are therefore widely used in various industries such as petroleum, chemical, water treatment, and grain storage. However, as modern storage tanks gradually become larger, this trend increases the ratio of tank radius to thickness, resulting in reduced rigidity and decreased resistance to wind loads.

[0003] Therefore, large storage tanks are generally equipped with wind-resistant rings. These rings form a circular structure on the tank, dispersing the force of wind and reducing the wind pressure on the tank, especially in areas with frequent strong winds. Wind-resistant rings are mainly used in storage tanks in petrochemical plants, refineries, and various oil depots to help these facilities remain stable under severe weather conditions and prevent structural damage caused by wind pressure.

[0004] Currently, the most common wind-resistant rings on storage tanks are ring-shaped truss structures, welded to the outside of the tank body near the top. Because the tank body and the wind-resistant ring are welded, localized high temperatures are generated on the tank wall when the wind-resistant ring connects to the tank. This does not affect ordinary storage tanks, but for enamel-lined assembled tanks, the enamel layer will be damaged by the high temperature, thus affecting the tank's corrosion resistance. Therefore, this type of wind-resistant ring cannot be used for enamel-lined assembled tanks. Furthermore, this type of wind-resistant ring cannot be used if open flames cannot be used at the construction site (e.g., if flammable or explosive gases or liquids are present).

[0005] Patent CN118164098A discloses a storage tank with improved wind resistance, including a wind-resistant ring. The wind-resistant ring comprises a main body, which includes a web, an annular channel steel, and an annular wall plate. The inner annular surface of the web is used for fixed connection to the outer annular surface of the annular wall plate, and the inner annular surface of the annular wall plate is used for fixed connection to the outer wall surface of the tank. The groove of the annular channel steel faces the storage tank, and the outer annular surface of the web is used for fixed connection to the side of the annular channel steel facing the ground, thereby improving wind resistance. However, the inner annular surface of the web and the outer annular surface of the annular wall plate are welded together, and the inner annular surface of the annular wall plate is welded to the outer wall surface of the tank, making it unsuitable for use in enamel-lined assembled storage tanks. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a wind-resistant ring structure for storage tanks, which solves the problem that the current wind-resistant rings cannot be used for enamel-lined assembled storage tanks.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A wind-resistant ring structure for a storage tank includes at least two arc-shaped beams arranged circumferentially on the outer side of the storage tank near the top, and a first support member spaced circumferentially between each arc-shaped beam and the tank wall. The arc-shaped beams are detachably connected end to end to form a ring. The first support member includes a fourth connecting plate, a second support rod, and a third connecting plate arranged sequentially from the inside to the outside along the diameter of the storage tank. The fourth connecting plate and the third connecting plate are respectively fixedly connected to one end of the second support rod. The fourth connecting plate is detachably connected to the tank wall, and the third connecting plate is detachably connected to the arc-shaped beam. The second support rod is arranged radially along the storage tank.

[0009] Furthermore, a second support is provided between two adjacent first support members. Each second support member includes a second connecting plate detachably connected to the inside of the arc-shaped beam, two first support rods fixedly connected to the inside of the second connecting plate in a figure-eight shape, and two first connecting plates fixedly connected to the inside ends of the two first support rods respectively. Both first support rods are arranged in a horizontal direction, and the first connecting plates are detachably connected to the tank wall.

[0010] Furthermore, the two first support rods in each second support member are symmetrically arranged, and the plane of symmetry of the two first support rods passes through the axis of the storage tank.

[0011] Furthermore, a fifth connecting plate is provided at the joint between adjacent curved beams, and the two adjacent curved beams are connected to the fifth connecting plate by bolts.

[0012] Furthermore, a base plate is fixedly connected to the tank wall at a position corresponding to the fourth connecting plate and / or the first connecting plate. A double-ended stud is fixedly connected to the base plate. The fourth connecting plate and / or the first connecting plate are provided with a notch for the double-ended stud to pass through. The fourth connecting plate and / or the first connecting plate are connected to the tank wall by the double-ended stud and a nut. The opening direction of the notch is downward.

[0013] Furthermore, the arc-shaped beam is made of channel steel, with the channel facing the tank wall.

[0014] Furthermore, the fifth connecting plate and the arc-shaped beam are connected by bolts passing through the fifth connecting plate and the arc-shaped beam, and nuts screwed onto the bolts. The fifth connecting plate is provided with a strip-shaped hole, which is arranged along the circumference of the arc-shaped beam.

[0015] The positive effects of this utility model are:

[0016] This invention features an arc-shaped beam, which is connected to the tank wall via first and second support members using studs and nuts. Therefore, this invention eliminates the need for welding during installation, preventing localized high temperatures on the tank wall and thus preventing the enamel layer from peeling off. Since no open flame is required during installation, it is particularly suitable for environments containing flammable or explosive gases, liquids, or solids. Furthermore, this invention is packaged and shipped in bulk, requiring assembly on-site, thus reducing storage and transportation space and lowering storage and logistics costs. On-site connection can be achieved using appropriate fasteners; the absence of welding improves construction efficiency. Attached Figure Description

[0025] Example 1

[0026] like Figures 1 to 4As shown, a wind-resistant ring structure for a storage tank includes sixteen arc-shaped beams 2 arranged circumferentially on the outer side of the storage tank near the top, and first support members 4 spaced circumferentially between each arc-shaped beam 2 and the tank wall 1. The arc-shaped beams 2 are detachably connected end to end by fasteners to form a ring. The first support member 4 includes a rectangular fourth connecting plate 11, a second support rod 10, and a rectangular third connecting plate 9 arranged sequentially from the inside to the outside along the diameter of the storage tank. The second support rod 10 is made of angle iron, and the fourth connecting plate 11 and the third connecting plate 9 are both cut from steel plates. The arc-shaped beams 2 are all bent from channel steel, with the channel facing the tank wall 1 during installation.

[0027] The fourth connecting plate 11 and the third connecting plate 9 are respectively welded to one end of the second support rod 10. The fourth connecting plate 11 is connected to the base plate 3 pre-welded to the tank wall 1 by fasteners consisting of double-ended studs and nuts. The third connecting plate 9 is connected to the arc beam 2 by bolts and nuts. The second support rod 10 is arranged radially along the storage tank.

[0028] The substrate 3 is pre-welded to the outside of the tank wall 1 before the enameling process of the storage tank, and has threaded holes, which can increase the local rigidity and stress area of ​​the tank wall 1 and prevent the tank wall 1 from deforming under stress.

[0029] A fifth connecting plate 12 is provided at the joint between adjacent curved beams 2, and the two adjacent curved beams 2 are connected to the fifth connecting plate 12 by fasteners consisting of bolts and nuts.

[0030] In actual installation, firstly, double-ended studs are inserted into the threaded holes on the base plate 3. Then, the fourth connecting plate 11 is passed through the double-ended studs and pressed onto the base plate 3 with nuts. After all the first support members 4 are installed, the sixteen arc-shaped beams 2 are connected to the third connecting plate 9 with bolts and nuts respectively. The sixteen arc-shaped beams 2 are then connected end to end with the fifth connecting plate 12 and corresponding bolts and nuts.

[0031] This invention eliminates the need for welding during installation, thus preventing the generation of high temperatures in the tank wall 1 and preventing the enamel layer on the tank wall 1 from peeling off. Since no open flame is required during installation, it is particularly suitable for environments containing flammable or explosive gases, liquids, or solids.

[0032] Furthermore, this invention can be stored and shipped in bulk, and then assembled on-site, thereby reducing the storage and transportation space required and lowering storage and logistics costs. On-site, it can be connected using appropriate fasteners, eliminating the need for welding and thus improving construction efficiency.

[0033] When the wind blows towards the tank wall 1, the arc beam 2 can increase the rigidity of the tank wall 1, thereby reducing the deformation of the tank wall 1 and improving the wind resistance of the tank.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that:

[0036] A second support member 5 is provided between two adjacent first support members 4. Each second support member 5 includes a rectangular second connecting plate 8 detachably connected to the inner side of the arc-shaped beam 2, two first support rods 7 fixedly connected to the inner side of the second connecting plate 8 in a figure-eight shape, and two rectangular first connecting plates 6 respectively fixedly connected to the inner ends of the two first support rods 7. The first connecting plate 6 and the second connecting plate 8 are both cut from steel plates, and the first support rods 7 are made of angle iron. The ends of the two first support rods 7 connected to the second connecting plate 8 are close to each other, and the other ends are far apart. Both first support rods 7 are arranged in a horizontal direction. The first connecting plate 6 is connected to the rectangular base plate 3 pre-welded to the tank wall 1 by fasteners consisting of double-ended studs and nuts. The two first support rods 7 in each first support member 4 are symmetrically arranged, and the plane of symmetry of the two first support rods 7 passes through the axis of the storage tank.

[0037] Because the two first support rods 7 are arranged in a V-shape, the force perpendicular to the length of the first connecting member 4 caused by the circumferential movement of the arc beam 2 under wind force can be reduced, thus preventing fatigue fracture at the weld joints of the fourth connecting plate 11, the third connecting plate 9, and the second support rod 10 due to long-term stress. Furthermore, the addition of the second support member 5 increases the number of action points on the tank wall 1 by two for each member, further increasing the rigidity of the tank wall 1 and making the stress distribution on the tank wall 1 more uniform, thereby reducing the deformation of the tank wall 1 under wind force.

[0038] Example 3

[0039] like Figure 5 and Figure 6 As shown, the difference between this embodiment and Embodiment 2 is that:

[0040] The fourth connecting plate 11 and the first connecting plate 6 are provided with notches 13 for the double-ended studs to pass through. The fourth connecting plate 11 and the first connecting plate 6 are connected to the tank wall 1 by double-ended studs and nuts. The opening direction of the notches 13 is downward.

[0041] The first support component 4 and the second support component 5 can be pre-assembled with the arc beam 2 in the factory to form a wind-resistant ring unit. On site, double-headed studs are first installed on each base plate 3 and nuts are tightened. Then, the notch 13 on each wind-resistant ring unit is inserted into the corresponding double-headed stud, and the nuts are tightened. Finally, the fifth connecting plate 12 is installed, which can further improve the installation efficiency.

[0042] The fifth connecting plate 12 and the arc-shaped beam 2 are connected by bolts passing through both the fifth connecting plate 12 and the arc-shaped beam 2, and nuts screwed onto the bolts. The fifth connecting plate 12 has a strip-shaped hole, which is arranged along the circumference of the arc-shaped beam 2. By providing the strip-shaped hole, even if two adjacent arc-shaped beams 2 are offset in the circumferential direction, it can be compensated through the strip-shaped hole, thereby facilitating on-site installation.

[0043] The above-described embodiments are detailed and specific, illustrating preferred embodiments of the present utility model. They are only used to illustrate the technical ideas and features of the present utility model, with the aim of enabling those skilled in the art to understand the content of the present utility model and implement it accordingly. However, they are not limited to the present utility model, and the patent scope of the present utility model cannot be limited by this embodiment alone. That is, any equivalent changes or modifications made to the spirit disclosed in the present utility model, without departing from the structure of the present utility model, such as local improvements within the system and modifications or transformations between subsystems, are still within the patent scope of the present utility model.
