[0002] With the rapid development of industries such as petrochemicals and energy storage, the demand for large storage tanks as key infrastructure is increasing. This places higher and higher requirements on the connection between steel storage tanks and concrete foundations. Nowadays, the two are mostly fixed by screw and nut locking or direct welding.

[0003] However, with existing technology, after the screw is fixed, the stress at the connection point is too concentrated, and the screw is exposed to the outside, making it susceptible to corrosion and damage from external rainwater. At the same time, it is inconvenient to monitor the strain at the connection point, which will affect the firmness and stability of the connection between the steel storage tank and the concrete foundation. Therefore, it is necessary to design a connection structure between the steel storage tank and the concrete foundation. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] A preferred embodiment of the connection structure between the steel storage tank and the concrete foundation provided by this utility model is, for example... Figures 1 to 5 The diagram illustrates a connection structure between a steel storage tank and a concrete foundation, comprising a concrete base 4; a connecting seat 3 embedded inside the concrete base 4, with a screw 8 fixedly connected at equal angles to the top of the connecting seat 3; a steel storage tank body 1 positioned at the top of the connecting seat 3; and pre-drilled holes at equal angles around the bottom periphery of the steel storage tank body 1 for the screw 8 to pass through. The connection structure also includes a nut 10, through which the screw 8 passes, and is threadedly connected to the screw 8 via the nut 10, thus achieving a positioning connection between the steel storage tank body 1 and the connecting seat 3. The connection structure further includes a fixing plate 2 fixedly connected at equal angles to the upper periphery of the connecting seat 3, with an FBG sensor 7 fixedly connected to the upper end of the inner wall of the fixing plate 2; and a shielding assembly 6 assembled at equal angles around the bottom periphery of the steel storage tank body 1, which provides rain protection for the screw 8 and the nut 10.

[0021] It should be noted that some existing connection structures between steel storage tanks and concrete foundations still have certain shortcomings in actual use. The stress at the connection is too concentrated, and the bolts are exposed and susceptible to erosion and damage from external rainwater. At the same time, it is inconvenient to monitor the strain at the connection nodes, which in turn affects the firmness and stability of the connection between the steel storage tanks and the concrete foundations.

[0022] In a further preferred embodiment of this utility model, the shielding component 6 includes: a fixed seat 601 fixedly connected at equal angles to the periphery of the bottom end of the steel storage tank body 1, a limiting groove 603 is provided on one side of the fixed seat 601, and a fixing groove 604 is provided inside the fixed seat 601 on one side of the limiting groove 603; a positioning block 605 movably connected inside the fixing groove 604, a pull rod 606 extending to the outside of the fixed seat 601 is fixedly connected to one end of the positioning block 605, a fixing spring 607 is wound around the surface of the pull rod 606, and the two ends of the fixing spring 607 are fixedly connected to the inner wall of the fixing groove 604 and one side of the positioning block 605, respectively; and a shielding cover 602 set at equal angles to the periphery of the bottom end of the steel storage tank body 1, a limiting block 609 is fixedly connected to the lower end of one side of the surface of the shielding cover 602, the limiting block 609 and the interior of the limiting groove 603 form a locking structure, and a slot 608 is provided on one side of the limiting block 609.

[0023] In this embodiment, after the steel storage tank body 1 and the connecting seat 3 are securely installed through the threaded engagement of the screw 8 and nut 10, the shield 602 can be snapped between the fixed seat 601 and the retaining seat 11, causing the retaining block 9 to snap into the retaining seat 11 and the limiting block 609 to snap into the limiting groove 603. Furthermore, the limiting block 609 and the positioning block 605 are curved on one side, allowing the limiting block 609 to smoothly snap down. This automatically causes the positioning block 605 to slide, driving the pull rod 606 to slide and compress the fixing spring 607. Once the limiting block 609 is fully engaged in the limiting groove 603, the elastic force of the fixing spring 607 can be used to make the positioning block 605 slide into the groove 608, thus achieving a secure engagement of the shield 602. This shield 602 can then protect the screw 8 and nut 10 from rain, preventing external rainwater from corroding them. When disassembly is required, the pull rod 606 can be manually pulled to make the positioning block 605 slide and compress the fixing spring 607 until it is completely disengaged from the groove 608, and then the shield 602 can be pulled upwards.

[0024] In a further preferred embodiment of the present invention, the top of the shield 602 is frustum-shaped, and the area of ​​the cross-sectional opening inside the shield 602 is greater than the area of ​​the cross-sectional opening of the nut 10.

[0025] In this embodiment, the use of a frustum-shaped shield 602 can effectively prevent rainwater from accumulating at the top of the shield 602.

[0026] In a further preferred embodiment of the present invention, the positioning block 605 and the slot 608 form an engaging structure, and one side of the top of the positioning block 605 and one side of the bottom of the limiting block 609 are arc-shaped.

[0027] In this embodiment, the arc-shaped positioning block 605 and limiting block 609 are used so that when the limiting block 609 is engaged with the limiting groove 603, the positioning block 605 can slide automatically.

[0028] In a further preferred embodiment of the present invention, a locking block 9 is fixedly connected to the other side of the surface of the shield 602, and a locking seat 11 is fixedly connected to the surface of the steel tank body 1 on one side of the fixing seat 601.

[0029] In a further preferred embodiment of the present invention, the card block 9 and the card seat 11 form an engaging structure, and the openings inside the card block 9 and the card seat 11 are convex in shape.

[0030] In this embodiment, the engagement between the convex locking block 9 and the inside of the locking seat 11 is used to improve the firmness and stability of the initial engagement installation of the shield 602.

[0031] In a further preferred embodiment of this utility model, the fixing plate 2 is C-shaped, with the opening facing the side of the connecting seat 3, and the top of the fixing plate 2 is set with an inclined surface.

[0032] In this embodiment, the use of a fixed plate 2 with a sloping top can prevent rainwater from accumulating at the top of the fixed plate 2.

[0033] In a further preferred embodiment of this utility model, the connecting seat 3 is shaped like an inverted bowl, and the top end of the connecting seat 3 and the bottom end of the screw 8 are welded together as an integrated structure.

[0034] In this embodiment, the inverted bowl-shaped connecting seat 3 can be used to distribute the stress and improve the firmness and stability of the steel storage tank body 1 after installation.

[0035] In a further preferred embodiment of this utility model, reinforcing nails 5 are welded at equal angles to the inner wall of the connecting seat 3, and one end of the reinforcing nail 5 is conical.

[0036] In this embodiment, the welded reinforcing nails 5 are used to improve the gripping stability between the connecting seat 3 and the inside of the concrete base 4.

[0037] In summary, firstly, the connecting seat 3 and the reinforcing nail 5 are embedded inside the concrete base 4. Then, after the concrete base 4 has completely solidified, the steel tank body 1 can be lifted and placed on top of the connecting seat 3. After the screw 8 passes through the reserved hole at the bottom of the steel tank body 1, the nuts 10 are tightened on the surface of the screw 8 in sequence to achieve a firm installation between the connecting seat 3 and the top of the steel tank body 1. At the same time, the inverted bowl-shaped connecting seat 3 can distribute the stress, and the reinforcing nail 5 can further improve the firmness and stability of the steel tank body 1 after installation. Then, the shield 602 is sequentially positioned between the fixed base 601 and the card holder 11, causing the card block 9 to engage with the inside of the card holder 11, and the limiting block 609 to engage with the inside of the limiting groove 603. The limiting block 609 and the positioning block 605 are curved on one side, allowing the limiting block 609 to smoothly engage. This automatically causes the positioning block 605 to slide, driving the pull rod 606 to slide and compress the fixing spring 607. Once the limiting block 609 is fully engaged in the limiting groove 603, the elasticity of the fixing spring 607 allows the positioning block 605 to slide and engage. The shield 602 is securely engaged with the slot 608, thus protecting the screw 8 and nut 10 from rain and preventing corrosion from external rainwater. When disassembly is required, the lever 606 can be manually pulled to slide the positioning block 605 to compress the fixing spring 607 until it is completely disengaged from the slot 608, and then the shield 602 can be pulled upwards. At the same time, the FBG sensor 7 monitors the connection between the steel tank body 1 and the connecting seat 3 to facilitate timely detection of faults and reduce potential hazards.
