Description

Technical Field

[0001] The present invention relates to the field of thin - film storage tanks, and particularly to a pump tower base device for a thin - film storage tank and an installation method thereof. Background Art

[0002] A cryogenic thin - film storage tank is a large - scale device for storing cryogenic media such as liquefied natural gas. Its structure includes a concrete outer tank, an inner tank, and a pump tower and other components. The pump tower base, as a key structure connecting the pump tower and the concrete foundation, its design directly affects the safety, stability, and transmission efficiency of liquefied natural gas transmission.

[0003] Currently, the pump tower bases in the prior art are mainly applicable to thin - film storage tanks with a bottom - centered symmetric layout. This kind of base adopts an integral support structure and is huge in volume. When applied to a thin - film storage tank, it will seriously interfere with the continuity of the corrugated plate, resulting in corrugation fracture. Secondly, the corrugated plate, as a key shielding component of the storage tank, its continuity is crucial for the sealing effect and heat - preservation performance. The fracture caused by the traditional base passing through the corrugated layer will form a cryogenic "thermal bridge", leading to leakage of cryogenic media, not only reducing the heat - preservation efficiency but also possibly causing cracking of the concrete foundation. In addition, the existing base structure is difficult to effectively integrate with the rectangular corrugated system, increasing the installation difficulty and cost.

[0004] Therefore, there is an urgent need to propose a pump tower base device for a thin - film storage tank and an installation method thereof to solve the above problems. Summary of the Invention

[0011] Further, a main - layer plywood board is arranged between the main - layer corrugated plate and the sub - layer corrugated plate.

[0012] Further, it further includes a sub - layer plywood board and polyurethane; the sub - layer plywood board is arranged on both sides of the polyurethane to form an insulating box, and the insulating box is arranged around the support base and is located between the sub - layer corrugated plate and the steel plate and the concrete foundation.

[0013] Further, a resin mastic is arranged between the insulating box and the steel plate and the concrete foundation.

[0014] Further, it further includes glass wool; there is a first filling space between the main - layer wing plate and the sub - layer wing plate; there is a second filling space between the sub - layer wing plate, the support base, the insulating box and the steel plate; the glass wool is filled into the first filling space, the second filling space and the interior of the support base.

[0015] Further, a guiding mechanism is arranged on the main base.

[0016] Further, the corrugated plate includes longitudinal corrugations and transverse corrugations; the longitudinal corrugations and the transverse corrugations are perpendicular and intersect to form a grid - like structure with multiple grids; the number of the wing plates and the support bases is correspondingly set to four, and the four wing plates are evenly distributed in a rectangle; the four wing plates are respectively located in four different regions of the grid - like structure; the four support bases respectively pass through the corresponding wing plates.

[0017] In addition, the present invention also provides an installation method for the base device of the thin - film storage tank pump tower, which is used to install the base device of the thin - film storage tank pump tower as described above, and specifically includes the following:

[0018] Embed steel plates in the concrete foundation;

[0019] Install a plurality of support bases on the steel plates, connect and pass through the wing plates;

[0020] Form a shielding layer by connecting the corrugated plate and the wing plate;

[0021] Install a support platform on the support base, make the shielding layer located below the support platform, and install a main base above the support platform.

This setting is particularly applicable to thin-film storage tanks with a rectangular layout at the bottom, improving the continuity of the corrugated plates, enhancing the sealing performance of the storage tank, and extending the service life of the storage tank.

[0026] In addition, by setting a main-layer corrugated plate and a sub-layer corrugated plate to form a primary and secondary double-layer shielding structure, more reliable sealing protection is provided. Filling heat-insulating materials in the gaps between the support bases effectively avoids the phenomenon of cold leakage and improves the overall heat-insulating performance. The multiple support bases are evenly distributed and are respectively arranged in four different regions of the grid-like structure formed by the corrugated plates as a whole, enabling the corrugated plates to be continuously arranged without disturbing the original layout of the corrugated plates, and at the same time forming a stable support structure, reducing the installation difficulty and manufacturing cost.

Detailed implementation manners

[0034] The following will describe a thin-film storage tank pump tower base device and its installation method of the present invention in more detail with reference to the drawings, in which the preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present invention.

[0035] In the following paragraphs, the present invention will be described more specifically by way of example with reference to the drawings. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0036] As Figure 1 shown, an embodiment of the present invention provides a thin-film storage tank pump tower base device, which includes a main base 1, a support platform 2, a plurality of support seats 3, a corrugated plate 4, and a wing plate 5.

[0037] Specifically, the main base 1 and the support seat 3 are respectively installed above and below the support platform 2; the wing plate 5 is connected to the corrugated plate 4 to form a shielding layer, and the shielding layer is located below the support platform 2; the support seat 3 passes through the wing plate 5, one end is connected to the support platform 2, and the other end extends into the concrete foundation 8 and is connected to the steel plate 9.

[0038] Among them, the support seat 3 and the wing plate 5 can be integrally formed. The wing plate 5 is located between adjacent corrugated plates 4, and there is a space between a plurality of support seats 3, and there are some corrugated plates 4 in the space, and some of the corrugated plates 4 are located between adjacent wing plates 5. For further reference, see Figure 1 shown.

[0039] In one embodiment, the main base 1 is of a cylindrical structure, and can also be set as a rectangular column structure according to needs. The specific dimensions and materials of the main base 1 can be set according to actual requirements, which can effectively bear the load of the pump tower and improve the structural stability. The support platform 2 can be of a disc-shaped structure or a rectangular structure. The diameter or side length of the support platform 2 is larger than that of the main base 1, and a plurality of reserved connection holes are evenly arranged around it for connecting with the support seat 3. The top surface of the support platform 2 and the bottom surface of the main base 1 are fixedly connected by welding, which can enhance the stability and load-bearing capacity of the overall structure. Compared with the thick structure of the traditional pump tower base, the device of the present invention is designed such that a plurality of support seats 3 are distributed near the corrugations of the corrugated plate 4, so that the corrugated plate 4 can be continuously arranged, thereby solving the problem that the overly large volume of the traditional pump tower base affects the corrugation continuity and improving the sealing performance of the storage tank.

[0040] In this embodiment, as shown in combination with Figure 2 and Figure 3 , the corrugated plate 4 includes a main layer corrugated plate 41 and a secondary layer corrugated plate 42 arranged from top to bottom. Specifically, the wing plate 5 includes a main layer wing plate 51 and a secondary layer wing plate 52 arranged from top to bottom; the main layer corrugated plate 41 and the main layer wing plate 51 are connected to form a main shielding layer, and the secondary layer corrugated plate 42 and the secondary layer wing plate 52 are connected to form a secondary shielding layer; the support seat 3 sequentially passes through the main layer wing plate 51 and the secondary layer wing plate 52, and the support seat and the wing plate are fixedly connected by welding.

[0041] Furthermore, a main layer plywood 6 is provided between the main layer corrugated plate 41 and the secondary layer corrugated plate 42. Preferably, the main layer plywood 6 can be made of a specially treated low-temperature resistant material and filled in the space between the main layer corrugated plate 41 and the secondary layer corrugated plate 42 to form a continuous heat insulation layer. The main layer plywood 6 not only provides additional heat insulation protection, but also enhances the rigidity and stability of the structure of the corrugated plate 4, reducing deformation and stress concentration. The material and thickness of the plywood can be accurately calculated and selected according to actual requirements, so that it can still have good physical properties and heat insulation effect in extremely low temperature environments, further improving the performance and reliability of the overall shielding structure.

[0042] In a specific example, the main layer corrugated plate 41 is located on the outside, the secondary layer corrugated plate 42 is located on the inside, and the main layer plywood 6 is filled between the two corrugated plates 4. The main layer corrugated plate 41 and the secondary layer corrugated plate 42 are connected with the corresponding wing plates 5 to jointly form a double-layer shielding structure, thereby being able to improve the overall sealing performance and heat insulation effect, and effectively reducing low-temperature leakage and heat conduction.

[0043] In one embodiment, as shown in Figure 4As shown, this embodiment further includes a secondary layer of plywood 71 and polyurethane 72. Specifically, the secondary layer of plywood 71 is disposed on both sides of the polyurethane 72 to form an insulation box 7, and the insulation box 7 is disposed around the support base 3 and is located between the secondary corrugated plate 42, the steel plate 9, and the concrete foundation 8. The material of the secondary layer of plywood 71 can be selected according to actual needs, for example, it is made of a high-strength low-temperature resistant material. The insulation box 7 formed by the combination of the secondary layer of plywood 71 and polyurethane 72 is disposed around the support base 3, playing a role of heat insulation and protection. The insulation box 7 is located between the secondary corrugated plate 42, the steel plate 9, and the concrete foundation 8 (as can be seen from Figure 1 that the steel plate 9 and the concrete foundation 8 form an integral body, and the insulation box 7 is located between this integral body and the secondary corrugated plate 42), effectively blocking the heat conduction path and reducing the "thermal bridge" effect. The setting of this insulation box 7 can further enhance the heat insulation performance of the overall structure, especially in the transition area between the support base 3 and the secondary corrugated plate 42, providing more comprehensive heat insulation protection, significantly reducing the heat loss of the low-temperature storage tank, thereby improving the energy utilization efficiency and operation safety.

[0044] Preferably, a resin mortar 11 is disposed between the insulation box 7, the steel plate 9, and the concrete foundation 8. The resin mortar 11 fills the gap between the insulation box 7, the steel plate 9, and the concrete foundation 8 (as can be seen from Figure 1 that the steel plate 9 and the concrete foundation 8 form an integral body, that is, the resin mortar 11 fills the gap between the insulation box 7 and this integral body), playing a role of fixing the insulation box and transmitting the load.

[0045] Preferably, continuing to refer to Figure 1 shown, this embodiment further includes glass wool 10. Specifically, there is a first filling space between the main layer wing plate 51 and the secondary layer wing plate 52; there is a second filling space between the secondary layer wing plate 52, the support base 3, the insulation box 7, and the steel plate 9, and the glass wool 10 is filled into the first filling space, the second filling space, and the inside of the support base 3. It can effectively avoid the cold leakage phenomenon between components, improve the overall heat insulation effect, and reduce the conduction of low temperature to the concrete foundation 8. The filling of the glass wool 10 not only improves the heat insulation performance but also enhances the anti-vibration ability of the overall structure, reduces the structural stress caused by temperature changes and external vibrations, thereby extending the service life of the device.

[0046] In this embodiment, a guiding mechanism 12 is disposed on the main base 1 for guiding the vertical displacement of the pump tower and restricting the lateral displacement of the pump tower.

[0047] In a specific example, in combination with Figure 5As shown, the corrugated plate 4 includes longitudinal corrugations 43 and transverse corrugations 44. Specifically, the longitudinal corrugations 43 and the transverse corrugations 44 are perpendicular and intersect to form a grid-like structure with multiple grids; the number of the wing plates 5 and the support bases 3 is correspondingly set to four, and the four wing plates 5 (each wing plate 5 includes a main layer wing plate 51 and a secondary layer wing plate 52) are evenly distributed in a rectangle; the four wing plates 5 are respectively located at non-corrugated positions in four different regions of the grid-like structure; the four support bases 3 respectively pass through the corresponding wing plates 5 to avoid the corrugations and do not interfere with the continuity of the corrugations. In this embodiment, the four wing plates 5 are evenly distributed in a rectangle and are located in four different regions of the grid-like structure, so that the structure has symmetry and the load is evenly distributed.

[0048] In one embodiment, the support base 3 includes a connecting portion and an extending portion arranged from top to bottom. Specifically, the connecting portion is connected to the support platform 2, one end of the extending portion is connected to the connecting portion, and the other end passes through the wing plate 5 and is connected to the steel plate 9. The extending portion passes through the wing plate 5 and is firmly connected to the wing plate 5 and the steel plate 9 by welding to form a complete load transfer path.

[0049] In addition, as Figure 6 shown, this embodiment also proposes an installation method for the base device of the thin-film storage tank pump tower, which is used to install the base device of the thin-film storage tank pump tower as described above, and specifically includes the following steps:

[0050] S1. Embed the steel plate 9 in the concrete foundation 8;

[0051] S2. Install a plurality of support bases 3 on the steel plate 9, connect and pass through the wing plates 5;

[0052] S3. Connect the corrugated plate 4 and the wing plates 5 to form a shielding layer;

[0053] S4. Install the support platform 2 on the support base 3, make the shielding layer located below the support platform 2, and install the main base 1 above the support platform 2.

[0054] In this embodiment, first, before pouring the concrete foundation 8, accurately position and fix the steel plate 9 according to the design requirements so that its position corresponds precisely to the node positions of the subsequent installed corrugated plate 4. After the concrete is poured and reaches the design strength, a plurality of support bases 3 are evenly distributed and can be fixedly installed on the steel plate 9 by welding. Among them, the support base 3 passes through the wing plate 5 (that is, sequentially passes through the main layer wing plate 51 and the secondary layer wing plate 52 from top to bottom) and is integrally formed with the wing plate 5.

[0055] Secondly, fill the inside of each support base 3 with glass wool 10, then install an insulating box 7 around the support base, and fill the second filling space between the insulating box 7 and the support base 3 with glass wool 10. Then, install a secondary corrugated plate 42 on the insulating box 7, and connect the secondary corrugated plate 42 with the secondary wing plate 52 (fixed by welding, for example) to form a secondary shielding layer. Subsequently, set a main layer plywood 6 on the secondary corrugated plate 42, and fill the first filling space between the main layer wing plate 51 and the secondary wing plate 52 with glass wool 10. Then, install a main layer corrugated plate 41 on the main layer plywood 6, and connect the main layer corrugated plate 41 with the main layer wing plate 51 (fixed by welding, for example) to form a main shielding layer. Finally, a support platform 2 can be installed on multiple support bases 3, and a main base 1 can be installed above the support platform 2.

[0056] In summary, a thin-film storage tank pump tower base device and its installation method proposed by the present invention have the following advantages:

[0057] By arranging a plurality of support bases at the bottom of the support platform and arranging corrugated plates outside the support bases, and connecting the corrugated plates through wing plates to form a shielding layer, the support bases pass through the wing plates and are connected to the steel plates on the concrete foundation, solving the problem that the excessive volume of the traditional pump tower base affects the continuity of the corrugations. This setting is particularly suitable for thin-film storage tanks with a rectangular layout at the bottom, improving the continuity of the corrugated plates, enhancing the sealing performance of the storage tank, reducing the formation of low-temperature "thermal bridges", and extending the service life of the storage tank.

[0058] In addition, by arranging a main layer corrugated plate and a secondary layer corrugated plate to form a primary and secondary double-layer shielding structure, more reliable sealing protection is provided. Filling heat-insulating materials in the gaps between the support bases effectively avoids the phenomenon of cold leakage and improves the overall heat-insulating performance. A plurality of support bases are evenly distributed and are respectively arranged in four different regions of the grid-like structure formed by the corrugated plates as a whole, enabling the corrugated plates to be continuously arranged without disturbing the original arrangement of the corrugated plates, and at the same time forming a stable support structure, reducing the installation difficulty and manufacturing cost.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
