Description

Technical Field

[0001] The present invention relates to the field of storage tank installation. More specifically, the present invention relates to a modular rapid installation system and method for storage tanks. Background Art

[0002] Storage tanks are key infrastructures for storing liquids or gases in fields such as petrochemical industry and energy storage. Their installation quality directly affects storage safety and service life. Traditional storage tanks mostly adopt the on-site piece-by-piece assembly and welding process, which has defects such as long construction period, difficult precision control, and high environmental dependence. Modular storage tanks achieve factory production through prefabricated standardized arc-shaped wall panel units (i.e., modules), which can significantly reduce on-site operation time. However, for their rapid installation, core problems such as accurate module positioning, dynamic stress compensation, and multi-process collaborative control need to be solved. Although existing modular technologies optimize transportation and lifting efficiency through split structures, they still face challenges such as module docking misalignment, connection stress imbalance, and cumulative welding deformation under complex working conditions.

[0003] In the prior art, a patent with the authorized announcement number CN111853523B discloses a modular storage tank wall and its installation method, which adopts prefabricated arc-shaped block modules, forms through holes for connection by matching horizontal and vertical connection wedge-shaped openings with bolts, and sets prestressed duct strengthening structures inside the modules. This technology reduces the risk of high-altitude operations through a layered lifting and step-by-step fastening process, shortening the construction period by about 60 days compared with the traditional in-situ casting process. However, its connection relies on the mechanical cooperation of wedge-shaped openings and bolts, and the module positioning still uses a rigid base, lacking a dynamic compensation mechanism. When the module deforms due to lifting errors or external loads, it is easy to cause wedge-shaped opening misalignment or uneven prestress distribution. In addition, its staged fastening process does not integrate real-time stress monitoring, and there is no data linkage between bolt pre-tightening force adjustment and welding processes, making it difficult to effectively control the superposition of residual stresses.

[0004] Traditional storage tank installation mostly adopts the on-site layer-by-layer welding process, which has a long construction period and is restricted by environmental factors. Especially in the construction of large storage tanks, it is difficult to ensure the positioning accuracy of arc-shaped wall panels, and cumulative errors are likely to occur. Although existing modular technologies have tried to improve efficiency through prefabricated arc-shaped modules, the connection structure between modules is complex, and the positioning depends on manual adjustment, resulting in problems such as high installation misalignment rate and uneven stress distribution, affecting the sealing performance and structural stability of the storage tank.

[0005] For the phased construction process, existing methods mostly set fixed fastening parameters based on experience and do not establish a dynamic adjustment mechanism linked to real-time stress monitoring. Although the modular connection structure is optimized in the invention patent CN111853523B, its fastening process still relies on manual judgment of bolt pre-tightening force, and there is a lack of closed-loop control for the welding sequence and stress release. Some solutions attempt to introduce sensors for monitoring, but most are limited to single-dimensional data acquisition and fail to construct a three-dimensional attitude closed-loop adjustment system, resulting in limited improvement in installation efficiency and still having technical bottlenecks such as frequent manual intervention and large fluctuations in construction quality. Summary of the Invention

[0006] One object of the present invention is to solve at least the above problems and provide at least the advantages described hereinafter.

[0007] Another object of the present invention is to provide a rapid modular installation system for storage tanks, which realizes rapid module positioning through the precise cooperation of a stepped plug-in structure and conical positioning columns, combines a four-stage fastening process with the real-time feedback mechanism of a dynamic compensation adjustment component to effectively balance the distribution of connection stress and avoid the accumulation of welding deformation; the closed-loop control of the electric servo pushing unit cooperating with the contact pressure sensor can automatically correct the module attitude deviation, reduce manual intervention, significantly improve the installation efficiency and the structural stability of the storage tank, and shorten the construction period.

[0008] To achieve these and other advantages in accordance with the present invention, there is provided a rapid modular installation system for storage tanks, comprising: A storage tank wall module group, which includes several standard arc modules spliced into a storage tank wall. At both circumferential ends of any standard arc module, there are respectively provided a male connection end and a female connection end of a plurality of stepped plug-in structures, and at the bottom of any standard arc module, there are provided a plurality of connecting plates with conical positioning holes; at the corresponding male connection end and female connection end of adjacent standard arc modules, there are connecting bolts, and a strain detection ring is sleeved on the connecting bolts; An adaptive positioning base, which includes a base body and a plurality of conical positioning column arrays arranged on the body. The conical positioning columns are adapted to the conical positioning holes, and three contact pressure sensors are integrally arranged on the outer side wall of the conical positioning columns at intervals of 120°; A dynamic compensation adjustment component, which includes a plurality of groups of electric servo pushing units corresponding to the number of standard arc modules and arranged around the base body. Any group of electric servo pushing units includes a pair of electric servo pushing units respectively located on both sides of the standard arc module. At the top of the telescopic rod of any electric servo pushing unit, there is a module clamping arm, and a roller array matching the curvature of the standard arc module is arranged on the working surface of the module clamping arm; Wherein, after adjacent standard arc modules are hoisted onto the adaptive positioning base under the guidance of the conical positioning columns, the adjacent standard arc modules are fastened in stages: In the first tightening stage, the connecting bolts are pre-tightened to 80 - 85% of the standard pre-tightening force. In the second tightening stage, 20 - 35% of the total length of the welded seams are sealed by welding. In the third tightening stage, the connecting bolts are tightened to the standard pre-tightening force. In the fourth tightening stage, the remaining seams are sealed by welding. Before the first tightening stage, the second tightening stage, and the third tightening stage are executed, if the difference in the values fed back by the three contact pressure sensors on any conical positioning post of any standard arc module > 5%, then the electric servo jacking units on both sides of the standard arc module are triggered to dynamically adjust the three-dimensional attitude of the standard arc module.

[0009] Preferably, the male connection end includes a guiding key protruding from the circumferential end face of the standard arc module. The guiding key is provided with a first guiding block, a second guiding block, and a third guiding block arranged in a stepped manner. The first guiding block is arranged away from the standard arc module. The thicknesses of the first guiding block, the second guiding block, and the third guiding block are 0.2, 0.4, and 0.7 times the wall thickness of the standard arc module respectively. The female connection end includes a key groove arranged on the circumferential end face of the standard arc module. The shape of the key groove is adapted to the shape of the guiding key, and a silicone rubber waterproof buffer cushion layer is arranged in the key groove. The compression and rebound rate of the silicone rubber waterproof buffer cushion layer is 35 - 40%.

[0010] The present invention further claims to protect the installation method of the modular rapid installation system for the storage tank, including: S1. Hoist adjacent standard arc modules so that the conical positioning holes of any standard arc module are in contact with the corresponding conical positioning posts for initial positioning. When the male connection end and the female connection end of adjacent standard arc modules are inserted, the stepped insertion structure is used to gradually guide and compress the silicone rubber waterproof buffer cushion layer. S2. Execute the tightening operation and dynamic compensation in stages: S21. In the first tightening stage: Synchronously pre-tighten all connecting bolts to 80 - 85% of the standard pre-tightening force. S22. In the second tightening stage: Select stress concentration areas along the seam length direction for segmented skip welding, and the welding length is 20 - 35% of the total seam. S23.

In the fourth tightening stage: Complete the welding of the remaining seams. S3. Hoist the next standard arc module in sequence and repeat step S2. S4. Repeat step S3 until all standard arc modules are installed. Among them, before the start of each fastening stage of S21 to S23, the system automatically checks the pressure sensor data of all conical positioning columns. When the difference in the values of the three sensors of the same conical positioning column is > 5%, the electric push units on both sides of the corresponding standard arc module are controlled to perform three-dimensional attitude adjustment.

[0011] Preferably, during the welding in step S22, the roller array of the module clamping arm maintains a reciprocating micro-movement of 0.5 to 1.2 mm / s to release the welding stress; during the welding in step S24, the dynamic compensation adjustment component continuously provides a radial binding force of 0.05 to 0.15 Mpa.

[0012] Preferably, the implementation method of the system automatically checking and performing three-dimensional attitude adjustment includes: Collect the data of the three contact pressure sensors of all conical positioning columns. When it is detected that the difference in the real-time collected data of the three contact pressure sensors of any conical positioning column is > 5%, determine the inclination direction of the standard arc module where it is located through the triangulation algorithm: according to the phase distribution of the three contact pressure sensors in the 120° circumferential direction, establish a pressure deviation vector model in the cylindrical coordinate system, and map the pressure deviation to the pitch angle deviation and horizontal radial displacement deviation of the module around the vertical axis; Calculate the compensation displacement amount of the module clamping arms on both sides according to the inclination direction of the standard arc module where it is located, and generate a multi-axis linkage control instruction: convert the pitch angle deviation into the telescopic stroke difference of the corresponding electric servo push unit group, convert the horizontal displacement deviation into the synchronous telescopic amount of the two electric servo push units in the same group, and form a closed-loop control through the real-time feedback of the contact reaction force of the roller array; When performing dynamic compensation, control the electric servo push unit groups on both sides of the standard arc module where the target conical positioning column is located to perform alternating fine-tuning, and the adjustment amount each time does not exceed 0.5 mm until the difference in the values of the three pressure sensors drops to ≤ 3% and then lock the current attitude.

[0013] Preferably, the specific implementation steps of establishing a pressure deviation vector model in the cylindrical coordinate system according to the phase distribution of the three contact pressure sensors in the 120° circumferential direction include: Define the installation positions of the three contact pressure sensors distributed at 120° intervals as the three detection directions in the cylindrical coordinate system, and their azimuth angles θ are 0°, 120° and 240° respectively; Collect the pressure values P1, P2 and P3 of the three contact pressure sensors in real time, and calculate the pressure deviation values △P1, △P2 and △P3 of each contact pressure sensor according to the average pressure; Based on the cylindrical coordinate system, map the pressure deviation values of each contact pressure sensor to the vector components in the radial and tangential directions: Deviation components of the sensor at θ = 0°: △ρ1 = △P1 × cos0°, △γ1 = △P1 × sin0°; Deviation components of the sensor at θ = 120°: △ρ2 = △P2 × cos120°, △γ2 = △P2 × sin120°; Deviation components of the sensor at θ = 240°: △ρ3 = △P3 × cos240°, △γ3 = △P3 × sin240°; Synthesize the total deviation vector: Total radial deviation Σ△ρ = △ρ1 + △ρ2 + △ρ3; Total tangential deviation Σ△γ = △γ1 + △γ2 + △γ3.

[0014] Preferably, calculate the pitch angle △β of the amplitude calculation module of the total tangential deviation Σ△γ around the vertical axis of the standard arc module: △β = arctan(k1Σ△γ × L); Determine the horizontal radial displacement deviation △d of the standard arc module from the sign and amplitude of the total radial deviation Σ△ρ: △d = k2 × Σ△ρ; where L is the vertical distance from the top of the conical positioning post to the center of gravity of the corresponding standard arc module, m; k1 is the angle conversion coefficient, with a value of 2.5×10 -4 m / N; k2 is the radial displacement conversion coefficient, with a value of 3×10 -5 m / N.

[0015] Preferably, calculate the telescopic stroke difference △S between two groups of electric servo jacking units in the same group according to the pitch angle deviation △β and the geometric parameters of the standard arc module: △S = 2Lsin△β / D; Calculate the synchronous telescopic amount △X of two groups of electric servo jacking units in the same group according to the horizontal radial displacement deviation △d: △X = △d / cosλ; where D is the horizontal distance between two groups of electric servo jacking units in the same group, m; λ is the angle between the telescopic direction of the electric servo jacking unit consistent with the synchronous telescopic direction in two groups of electric servo jacking units and the horizontal plane, λ ≤ 10°.

[0016] The present invention has at least the following beneficial effects: First, the modular rapid installation system for storage tanks provided by the present invention realizes the rapid alignment and splicing of standard arc modules through the cooperation of the male connection end and the female connection end of the stepped plug-in structure and the precise guidance of the conical positioning post array. Combining the four-stage step-by-step fastening process (pre-tightening - local welding - final tightening - overall welding), it effectively balances the pre-tightening force distribution of the connecting bolts and avoids the superposition of welding residual stress and mechanical stress; The dynamic compensation adjustment component controls the attitude of the module based on the real-time data of the contact pressure sensor, improves the installation accuracy, shortens the construction period, and is suitable for the efficient construction of large storage tanks; Second, the modular rapid installation system for storage tanks provided by the present invention adopts a combined structure of stepped guiding keys and silicone rubber waterproof buffer pads. When the male connection end and the female connection end are inserted, the buffer layer is gradually compressed, which not only ensures the positioning accuracy of the rigid connection between modules, but also absorbs the lifting impact and thermal expansion and contraction deformation through a compression and rebound rate of 35-40%, improves the sealing performance of the module interface, the waterproof performance reaches the IP68 level, and at the same time reduces the risk of mechanical damage to the precision structure during the insertion process; Third, the installation method of the modular rapid installation system for storage tanks provided by the present invention effectively controls the welding deformation through the pre-tightening force gradient loading, skip welding stress release and temperature-related final tightening strategy. The roller array of the module clamping arm moves slightly at a speed of 0.5-1.2 mm / s during welding, combined with a radial binding force of 0.05-0.15 Mpa, effectively inhibits the deflection of the module caused by the shrinkage of the weld seam, and improves the qualified rate of the seam airtightness detection; Fourth, the installation method of the modular rapid installation system for storage tanks provided by the present invention is based on the three-dimensional attitude closed-loop regulation of the column coordinate system pressure deviation vector model. By real-time calculating the pitch angle △β and the horizontal displacement △d, and converting them into the telescopic stroke difference △S and the synchronous telescopic amount △X of the electric servo push unit, the sub-millimeter-level dynamic compensation of the module attitude is realized; shortens the adjustment time of the pressure sensor data difference, and each adjustment amount ≤ 0.5 mm, significantly improves the stability and automation level of the installation process; Fifth, the installation method of the modular rapid installation system for storage tanks provided by the invention accurately calibrates the angle and displacement conversion coefficients (k1, k2), combines the real-time feedback of the module geometric parameters (L, D, λ), and converts the pressure deviation amount into an executable multi-axis linkage control instruction; improves the attitude adjustment accuracy, and improves the stress distribution uniformity of the overall structure, and greatly extends the service life of the storage tank.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it according to the text of the specification.

[0020] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0021] As Figures 1 - 3 shown, the present invention provides a modular rapid installation system for storage tanks, including: A storage tank wall module group, which includes several standard arc modules 1 spliced into a storage tank wall. At both circumferential ends of any standard arc module 1, there are respectively provided a plurality of male connection ends 10 and female connection ends 11 with stepped plug-in structures, and at the bottom of any standard arc module 1, there are provided a plurality of connecting plates with tapered positioning holes; at the corresponding male connection ends 10 and female connection ends 11 of adjacent standard arc modules 1, there are connecting bolts, and a strain detection ring is sleeved on the connecting bolts; An adaptive positioning base 2, which includes a base body and an array of a plurality of tapered positioning columns 20 arranged on the body. The tapered positioning columns 20 are adapted to the tapered positioning holes, and three contact pressure sensors are integrally arranged on the outer side wall of the tapered positioning columns 20 at intervals of 120°; A dynamic compensation adjustment assembly, which includes a plurality of groups of electric servo jacking units corresponding to the number of the standard arc modules 1 arranged around the base body. Any group of electric servo jacking units includes a pair of electric servo jacking units respectively located on both sides of the standard arc module 1. At the top of the telescopic rod of any electric servo jacking unit, there is a module clamping arm, and a roller array matching the curvature of the standard arc module 1 is arranged on the working surface of the module clamping arm; Among them, after adjacent standard arc modules 1 are hoisted onto the adaptive positioning base 2 under the guidance of the tapered positioning columns 20, the adjacent standard arc modules 1 are fastened in stages: In the first fastening stage, the connecting bolts are pre-tightened to 80 - 85% of the standard pre-tightening force. In the second fastening stage, 20 - 35% of the total length of the seams is sealed and welded. In the third fastening stage, the connecting bolts are tightened to the standard pre-tightening force. In the fourth fastening stage, the remaining seams are sealed and welded; before the first fastening stage, the second fastening stage, and the third fastening stage are executed, if the difference in the values fed back by the three contact pressure sensors on any tapered positioning column 20 of any standard arc module 1 > 5%, then the electric servo jacking units on both sides of the standard arc module 1 are triggered to dynamically adjust the three-dimensional attitude of the standard arc module 1.

[0022] In the above technical solution, the modular rapid installation system for storage tanks achieves rapid and precise assembly through standardized module design and intelligent dynamic compensation technology. This technical solution realizes the modular rapid installation of storage tanks through the coordinated operation of the storage tank wall module group, the adaptive positioning base 2, and the dynamic compensation adjustment component. The storage tank wall module group is composed of several standard arc modules 1 spliced together. The standard arc module 1 adopts a male connection end 10 and a female connection end 11 with a stepped plug-in structure, which is convenient for splicing with each other. The bottom is provided with a connecting plate with a conical positioning hole, which cooperates with the adaptive positioning base 2. A strain detection ring sleeved on the connecting bolt can monitor the connection state in real time. The conical positioning column 20 of the adaptive positioning base 2 is adapted to the conical positioning hole of the standard arc module 1, and a contact pressure sensor is integrated on the outer wall to sense the stability of the module placement; the electric servo pushing unit of the dynamic compensation adjustment component is arranged on the adaptive positioning base 2 through the electric servo pushing unit mounting seat 21, and can dynamically adjust the module attitude. The installation is carried out in stages. In the first tightening stage, it is pre-tightened to 80-85% of the standard pre-tightening force. In the second stage, 20-35% of the total length of the sealed welding seams is welded, providing reasonable operation specifications for the installation process.

[0023] According to the above technical solution, in one of its specific implementation manners, the standard arc module 1 adopts a standardized arc steel plate structure, and Q345R pressure vessel steel (with a thickness of 12-25 mm) can be selected and hot-dip galvanized for anti-corrosion. Multi-stage stepped plug-in structures are arranged at both circumferential ends (i.e., the vertical ends of the standard arc module 1) of the standard arc module 1. The male connection end 10 is a protruding step, and the female connection end 11 is a matching groove, and a gapless fit is achieved with an H7 / g6 tolerance. A plurality of connecting plates with conical positioning holes are welded at the bottom of the standard arc module 1, forming a precise guide with the positioning column array on the base body. The connecting bolt (M24, 10.9 grade can be selected) is equipped with a KMR series strain detection ring to monitor the pre-tightening force of 0-500 kN in real time, with an error ≤ ±0.5%. The adaptive positioning base 2 is composed of a concrete casting matrix and a pre-embedded steel structure, such as Figure 2 and Figure 3As shown, the adaptive positioning base 2 can be cylindrical or square, and a conical positioning column 20 of alloy steel is arranged on its surface. The conical positioning column 20 integrates three TEConnectivity FS series contact pressure sensors, which are arranged in a circle of 120°. PLC control cables are embedded in the base body, and the sensor signals are transmitted to the S7-1500 main control system through the Siemens ET200SP module. The three-way pressure values ​​are compared in real time, and the compensation command is triggered when the difference is greater than 5%. The electric servo push unit of the dynamic compensation adjustment component adopts a ring layout, and the existing Bosch Rexroth CytroPac electric servo push unit can be selected. The electric servo push unit is set on the electric servo push unit mounting seat 21. Each standard arc module 1 is equipped with an electric servo push unit on both sides. The two electric servo push unit mounting seats 21 are symmetrically arranged relative to the corresponding standard arc module 1, and the telescopic rod is hinged to the 6061-T6 aluminum alloy clamping arm. The working surface of the clamping arm is equipped with a GCr15 bearing steel roller array, which is driven by a servo motor to achieve three-dimensional posture adjustment corresponding to the standard arc module 1. The PLC system dynamically calculates the compensation amount based on the pressure sensor data.

[0024] According to the above technical solution, a specific workflow of the modular rapid installation system of the storage tank is as follows: first, the adaptive positioning base 2 is placed at the installation position, and its tapered positioning column 20 array is used to wait for the installation of the standard arc module 1. Then the standard arc module 1 is hoisted, and under the guidance of the tapered positioning column 20, the tapered positioning hole at the bottom of the module is accurately matched with the positioning column. Then, the staged tightening link is entered. In the first tightening stage, the connecting bolts are pre-tightened to 80-85% of the standard pre-tightening force, and in the second tightening stage, 20-35% of the total length of the welded joint is sealed. In the third tightening stage, the connecting bolts are tightened to the standard pre-tightening force, and in the fourth tightening stage, the remaining joints are sealed and welded to complete the installation of the tank wall. During this process, the contact pressure sensor monitors the placement status of each module in real time. Before the first tightening stage, the second tightening stage and the third tightening stage are executed, if the difference in the values ​​fed back by the three contact pressure sensors on any conical positioning column 20 of any standard arc module 1 is greater than 5%, the electric servo pushing units on both sides of the standard arc module 1 will be triggered, and the three-dimensional posture of the standard arc module 1 will be dynamically adjusted through the roller array on the module clamping arm hinged on the top of the telescopic rod.

[0025] According to the above technical solution, on the one hand, the modular rapid installation system for the storage tank greatly improves the installation efficiency of the storage tank through modular design and phased fastening method. Compared with the traditional installation method, it can shorten the construction period and reduce the labor cost. On the other hand, the application of the dynamic compensation adjustment component and the contact pressure sensor ensures the accuracy and stability of the installation of each standard arc module 1, reduces the installation error, and improves the reliability of the overall structure of the storage tank. To a certain extent, the strain detection ring's real-time monitoring of the connecting bolts can also timely detect potential connection problems, enhance the safety of the storage tank during use, and reduce the later maintenance cost and safety hazards.

[0026] In one of the technical solutions, the male connection end 10 includes a guiding key protruding from the circumferential end face of the standard arc module 1. The guiding key is provided with a first guiding block, a second guiding block, and a third guiding block arranged in a stepped shape. The first guiding block is arranged away from the standard arc module 1. The thicknesses of the first guiding block, the second guiding block, and the third guiding block are 0.2, 0.4, and 0.7 times the wall thickness of the standard arc module 1 respectively. The female connection end 11 includes a keyway arranged on the circumferential end face of the standard arc module 1. The shape of the keyway is adapted to the shape of the guiding key, and a silicone rubber waterproof buffer cushion layer is arranged in the keyway. The compression and rebound rate of the silicone rubber waterproof buffer cushion layer is 35-40%.

[0027] In the above technical solution, the precise docking and stress buffering of the standard arc module 1 are realized through the cooperation of the stepped guiding key and the silicone rubber waterproof buffer cushion layer. In the circumferential connection of the standard arc module 1, precise splicing is realized by designing the male connection end 10 and the female connection end 11 with specific structures. The guiding key of the male connection end 10 is composed of a first guiding block, a second guiding block, and a third guiding block arranged in a stepped shape. Their thicknesses are 0.2, 0.4, and 0.7 times the wall thickness of the standard arc module 1 respectively. The stepped guiding key can realize step-by-step deep insertion, ensuring the accuracy and stability of the connection. The shape of the keyway of the female connection end 11 is adapted to the guiding key, and the silicone rubber waterproof buffer cushion layer arranged inside has a compression and rebound rate of 35-40%. Through its material properties, it can not only play a waterproof role but also buffer the pressure during module splicing, reducing the damage caused by rigid contact. The silicone rubber waterproof buffer cushion layer can be selected from sealing materials meeting industrial standards. The stepped guiding key and the keyway can also be prefabricated by machining and made of common metal materials such as stainless steel and carbon steel to ensure strength and durability.

[0028] According to the above technical solution, after the male connection end 10 and the female connection end 11 of the adjacent standard arc modules 1 are plugged together, they are tightened with connection bolts, and in cooperation with the adaptive positioning base 2 and the dynamic compensation adjustment assembly, the installation of the entire storage tank wall module group is completed. According to the above technical solution, firstly, the design of the stepped guiding keys and the mating key grooves improves the accuracy and efficiency of the splicing of the standard arc modules 1, avoids installation errors caused by connection misalignment, and further speeds up the modular installation process of the storage tank. Secondly, the application of the silicone rubber waterproof buffer cushion layer effectively improves the waterproof performance of the connection part of the storage tank wall, prevents external liquid from seeping into the storage tank, and ensures the safety of the substances stored in the storage tank. At the same time, its buffering effect can also reduce the wear and deformation caused by stress during the splicing and use of the modules, extend the service life of the storage tank, reduce the maintenance cost, and further enhance the stability and sealing performance of the overall structure of the storage tank, improving the reliability and safety of the storage tank under various working conditions.

[0029] The present invention further claims to protect the installation method of the modular rapid installation system for the storage tank, including: S1. Lift adjacent standard arc modules 1 so that the conical positioning holes of any standard arc module 1 contact and support the corresponding conical positioning posts 20 to establish an initial positioning. When the male connection end 10 and the female connection end 11 of the adjacent standard arc modules 1 are plugged together, the stepped plugging structure is used to gradually guide and compress the silicone rubber waterproof buffer cushion layer; S2. Execute the fastening operation and dynamic compensation in stages: S21. The first fastening stage: Synchronously pre-tighten all connection bolts to 80 - 85% of the standard pre-tightening force; S22. The second fastening stage: Select stress concentration areas along the seam length direction for segmented skip welding, and the welding length is 20 - 35% of the total seam; S23. The third fastening stage: When the temperature at the welding end drops below 80°C, synchronously load all connection bolts to the standard pre-tightening force; S24. The fourth fastening stage: Complete the welding of the remaining seams; S3. Lift the next standard arc module 1 in sequence and repeat step S2; S4. Repeat step S3 until all standard arc modules 1 are installed; Wherein, before the start of each fastening stage of S21 - S23, the system automatically verifies the pressure sensor data of all conical positioning posts 20. When the difference in the values of the three sensors of the same conical positioning post 20 > 5%, the electric jacking units on both sides of the corresponding standard arc module 1 are controlled to perform three-dimensional attitude adjustment.

[0030] In the above technical solution, first, in the initial positioning stage, the conical positioning holes at the bottom of the standard arc module 1 are used to contact and support the conical positioning posts 20 on the adaptive positioning base 2, realizing fast and accurate preliminary positioning; at the same time, the male connection end 10 and the female connection end 11 of adjacent modules are inserted through the stepped guide keys and key grooves, and the silicone rubber waterproof buffer cushion layer is compressed during the insertion process to complete the sealing preparation. In the fastening and dynamic compensation stage, operations are carried out in four stages. In the first fastening stage, the connecting bolts are pre-tightened to 80-85% of the standard pre-tightening force to provide the basic fastening force for subsequent operations; in the second fastening stage, 20-35% of the total joint seams are welded in segments by skip welding in the stress concentration area to disperse the welding stress; in the third fastening stage, after the temperature at the welding end drops below 80°C, the bolts are tightened to the standard pre-tightening force to ensure the connection strength; in the fourth fastening stage, the remaining welding is completed. Before each fastening stage, the data of the pressure sensors is verified. If the difference in the values of the three sensors of the same conical positioning post 20 is >5%, the three-dimensional attitude of the module is adjusted by using the electric servo pushing unit and the module clamping arm. The whole process fully combines the characteristics of each component of the system to achieve efficient and accurate installation.

[0031] According to the above technical solution, a specific working process is as follows: First, fix the adaptive positioning base 2 at the installation site. Subsequently, use the hoisting equipment to lift the adjacent standard arc module 1, align and contact the conical positioning hole at the bottom of the standard arc module 1 with the conical positioning column 20 on the base body to establish an initial stable positioning. During this process, the male connection end 10 of the adjacent standard arc module 1 is inserted into the female connection end 11 of the adjacent module. During the process of gradually inserting the stepped guiding key into the keyway, the silicone rubber waterproof buffer cushion layer is compressed to achieve preliminary sealing and positioning. Then, enter the phased tightening operation. The system automatically checks the data of the pressure sensors. If the difference in the values of the three sensors for the same conical positioning column 20 is >5%, immediately start the electric servo push units on both sides of the corresponding module, and adjust the module attitude through the roller array on the module clamping arm. In the first tightening stage, synchronously pre-tighten all connecting bolts to 80-85% of the standard pre-tightening force using tools. After the pre-tightening is completed, the system automatically checks the data of the pressure sensors. If the difference in the values of the three sensors for the same conical positioning column 20 is >5%, immediately start the electric servo push units on both sides of the corresponding module, and adjust the module attitude through the roller array on the module clamping arm. After the attitude adjustment is completed and the data meets the standard, enter the second tightening stage, determine the stress concentration area along the length direction of the joint, and perform segmented skip welding, with the welding length being 20-35% of the total joint. After the welding is completed and the temperature of the welded end drops below 80°C, the system checks and adjusts the data of the pressure sensors again, and then enters the third tightening stage, synchronously load all connecting bolts to the standard pre-tightening force, and continue with the fourth tightening stage to complete the welding of the remaining joints. Repeat the above steps, hoist and install the subsequent standard arc modules 1 in sequence until all modules are installed, and complete the construction of the storage tank wall.

[0032] According to the above technical solution, in terms of installation efficiency, the clear phased operation and modular design avoid the cumbersome process of the traditional installation method, greatly shorten the installation cycle of the storage tank, and improve the construction progress; in terms of installation quality, the preliminary positioning based on the combination of the conical positioning column 20 - conical alignment hole, male connection end 10 - female connection end 11 reduces redundant positioning, monitoring, and control steps. Through the cooperation of the conical positioning column 20 and the pressure sensors, as well as the real-time adjustment of the electric servo push unit, it ensures that the installation position of each standard arc module 1 is accurate and the connection is tight; the phased tightening and welding methods effectively disperse the stress, reduce the welding deformation, and improve the stability and reliability of the overall structure of the storage tank. At the same time, the application of the silicone rubber waterproof buffer cushion layer ensures the waterproof performance of the storage tank wall, and the monitoring of the connecting bolts by the strain detection ring not only accurately performs the tightening operation but also can timely detect potential problems, enhancing the safety of the storage tank during use, reducing the later maintenance cost and safety risks, and providing a strong guarantee for the long-term stable operation of the storage tank.

[0033] In one of the technical solutions, during the welding in step S22, the roller array of the module clamping arm maintains a reciprocating micro-movement at a speed of 0.5 - 1.2 mm / s to release the welding stress; during the welding in step S24, the power compensation adjustment component continuously provides a radial binding force of 0.05 - 0.15 Mpa.

[0034] The above technical solution further optimizes the welding process. Through the precise control of the module clamping arm and the power compensation adjustment component, effective management of the stress during the welding process is achieved. During the welding in the second fastening stage, the roller array of the module clamping arm reciprocates and micro-moves at a speed of 0.5 - 1.2 mm / s, which can not only keep an appropriate relative movement between the rollers and the surface of the standard arc module 1, but also does not affect the stability of the welding operation. Through the reciprocating micro-movement of the rollers, the local stress generated by welding can be timely dispersed, avoiding module deformation caused by stress concentration. During the welding process in the fourth fastening stage, the power compensation adjustment component continuously provides a radial binding force of 0.05 - 0.15 Mpa. This pressure range can be adjusted according to the actual specifications and materials of the storage tank module. Generally speaking, the larger the specification of the storage tank module and the harder the material, the greater the above radial binding force. By applying a stable radial binding force, the module maintains a relatively stable positional relationship during welding, and at the same time helps to offset the stress generated by welding, ensuring the welding quality. Common electric servo drive devices on the market can be used to control the micro-movement of the roller array, and the pressure adjustment device can achieve precise control of the radial binding force of the power compensation adjustment component.

[0035] According to the above technical solution, during the welding process, the reciprocating micro-movement of the roller array and the radial binding force provided by the power compensation adjustment component can effectively inhibit welding deformation, reduce defects such as weld cracks and pores caused by stress concentration, greatly improve the strength and reliability of the welded joint, and ensure the overall sealing performance of the storage tank wall. At the same time, it also avoids rework and repair caused by welding deformation, reduces the time loss during the installation process, and enables the modular installation of the storage tank to proceed more smoothly and efficiently. It even reduces the dependence on the welding technical level of the operators. Through standardized operation procedures and equipment control, it ensures that different construction teams can reach a high quality standard during the installation process, improves the standardization and consistency of the construction, and lays a solid foundation for the long-term safe and stable operation of the storage tank.

[0036] In one of the technical solutions, the implementation methods for the system to automatically verify and perform three-dimensional attitude adjustment include: Collect the data of the three contact pressure sensors of all the conical positioning posts 20. When the difference in the real-time collected data of the three contact pressure sensors of any conical positioning post 20 is > 5%, determine the tilt direction of the standard arc module 1 where it is located through the triangulation algorithm: According to the phase distribution of the three contact pressure sensors in the 120° circumferential direction, establish a pressure deviation vector model in the cylindrical coordinate system, and map the pressure deviation to the pitch angle deviation and the horizontal radial displacement deviation of the module around the vertical axis; Calculate the compensation displacement of the clamping arms of the modules on both sides according to the tilt direction of the standard arc module 1 where it is located, and generate a multi-axis linkage control command: Convert the pitch angle deviation into the telescopic stroke difference of the corresponding electric servo push unit group, and convert the horizontal displacement deviation into the synchronous telescopic amount of two electric servo push units in the same group, and form a closed-loop control through the real-time feedback of the contact reaction force of the roller array; When performing dynamic compensation, alternately fine-tune the electric servo push unit groups on both sides of the standard arc module 1 where the target conical positioning post 20 is located. The adjustment amount each time does not exceed 0.5 mm until the difference in the values of the three pressure sensors drops to ≤ 3% and then lock the current posture.

[0037] In the above technical solution, through the pressure sensor data acquisition, the triangulation algorithm calculation and the precise control of the electric servo push unit, the automatic dynamic adjustment of the three-dimensional posture of the standard arc module 1 is realized. The system first collects the data of the three contact pressure sensors distributed at intervals of 120° on the outer side wall of each conical positioning post 20 in real time. When the difference in the values of the three sensors on any conical positioning post 20 exceeds 5%, the posture adjustment mechanism is triggered. By establishing a pressure deviation vector model in the cylindrical coordinate system and using the triangulation algorithm to map the pressure difference to the pitch angle deviation and the horizontal radial displacement deviation of the module, the phase distribution of the three sensors in the circumferential direction forms a spatial positioning reference, and the direction and amplitude of the pressure imbalance directly correspond to the specific direction of the module tilt (such as forward tilt, backward tilt or radial offset around the vertical axis). Then, the system calculates the compensation displacement of the electric servo push units on both sides of the module according to the tilt direction: convert the pitch angle deviation into the telescopic stroke difference of the push units on both sides, so that the standard arc module 1 rotates and resets around the horizontal axis; the horizontal displacement deviation is converted into the synchronous telescopic amount of the push units in the same group to drive the module to translate radially. During the adjustment process, the contact reaction force of the roller array is real-time fed back to the control system to form a closed-loop control, ensuring that the adjustment amount each time does not exceed 0.5 mm until the difference in the values of the three sensors drops to within 3%, realizing the attitude calibration with millimeter-level accuracy.

[0038] According to the above technical solution, after the standard arc module 1 is hoisted to the adaptive positioning base 2 and the initial positioning is completed, the system continuously monitors the pressure sensor data of all the conical positioning columns 20. If the difference between the values of the three sensors of a certain conical positioning column 20 at the bottom of a module exceeds 5%, the triangular positioning algorithm is immediately started. Taking the top of the conical positioning column 20 as the origin, a cylindrical coordinate system is established, and the three sensors respectively correspond to the directions of 0°, 120°, and 240°. The vector sum of the pressure deviations in each direction is calculated to determine that the module tilts in the 240° direction and is accompanied by a radial displacement. The system then calculates the compensation parameters: converts the pitch angle deviation into the elongation difference of the electric servo push units on both sides of the module (for example, the left telescopic rod elongates 0.3 mm and the right one shortens 0.3 mm), and converts the horizontal displacement deviation into an instruction to elongate 0.2 mm synchronously on both sides, generating a multi-axis linkage control signal. Controls the alternating fine-tuning of the push units on both sides, and collects the pressure data in real time after each adjustment. If the difference is reduced to 4%, continue the fine-tuning; if the difference increases to 6% after a certain adjustment, the system automatically retreats to the previous operation and corrects the parameters. Until the difference between the values of the three sensors is stable within 3%, lock the current posture, complete the three-dimensional posture calibration of the module, and provide a stable structural basis for the subsequent fastening and welding processes.

[0039] According to the above technical solution, the automatic attitude adjustment mechanism based on the triangular positioning algorithm realizes the accurate quantitative analysis and dynamic compensation of the installation deviation of the module, avoids the inefficiency and errors of traditional manual measurement and adjustment, shortens the single-module attitude calibration time to the minute level, and greatly improves the overall installation efficiency. The closed-loop control and the millimeter-level fine-tuning strategy ensure the positioning accuracy of the standard arc module 1, control the stress uniformity error of each conical positioning column 20 within 3%, effectively reduce the problem of bolt stress concentration caused by the tilt of the standard arc module 1, and improve the structural strength and sealing performance of the splicing part of the storage tank wall. In addition, the adjustment parameters are corrected in real time through pressure feedback, and can adapt to the installation deviation under different working conditions (such as small foundation settlement, module processing tolerance), enhance the adaptability of the system to complex environments, and provide a reliable guarantee for the stability and safety of the long-term operation of the storage tank. At the same time, the standardized automatic calibration process reduces the dependence on manual experience, makes the construction quality easier to control, and is especially suitable for the rapid assembly of large-scale industrial storage tanks.

[0040] In one of the technical solutions, the specific implementation steps of establishing a pressure deviation vector model in the cylindrical coordinate system according to the phase distribution of three contact pressure sensors in the 120° circumferential direction include: Define the installation positions of the three contact pressure sensors distributed at 120° intervals as the three detection directions in the cylindrical coordinate system, and their azimuth angles θ are 0°, 120°, and 240° respectively; Real-time collect the pressure values P1, P2, and P3 of three contact pressure sensors, and calculate the pressure deviation values △P1, △P2, and △P3 of each contact pressure sensor according to the average pressure; Based on the cylindrical coordinate system, map the pressure deviation values of each contact pressure sensor into radial and tangential vector components: Deviation components of the sensor at θ = 0°: △ρ1 = △P1 × cos0°, △γ1 = △P1 × sin0°; Deviation components of the sensor at θ = 120°: △ρ2 = △P2 × cos120°, △γ2 = △P2 × sin120°; Deviation components of the sensor at θ = 240°: △ρ3 = △P3 × cos240°, △γ3 = △P3 × sin240°; Synthesize the total deviation vector: Total radial deviation Σ△ρ = △ρ1 + △ρ2 + △ρ3; total tangential deviation Σ△γ = △γ1 + △γ2 + △γ3.

[0041] The above technical solution is a detailed implementation of establishing a pressure deviation vector model in the cylindrical coordinate system. First, the system clearly defines the installation positions of three contact pressure sensors distributed at 120° intervals as three detection directions in the cylindrical coordinate system, and assigns azimuth angles 0°, 120°, and 240° respectively to construct a coordinate system. Then, the system real-time collects the pressure values P1, P2, and P3 of these three sensors, and calculates their average pressure, and then obtains the pressure deviation values △P1, △P2, and △P3 of each sensor. This step can clearly reflect the degree of difference between the pressure of each sensor and the average pressure. Then, based on the cylindrical coordinate system, map the pressure deviation values of each sensor into radial and tangential vector components. Using trigonometric function relationships, calculate the radial and tangential values of the sensor deviation components at different azimuth angles. For example, the radial deviation component △ρ1 of the sensor at 0° is equal to △P1 multiplied by cos0°, and the tangential deviation component △γ1 is equal to △P1 multiplied by sin0°. Finally, add the radial and tangential deviation components of all sensors respectively to obtain the total radial deviation Σ△ρ and the total tangential deviation Σ△γ, thereby synthesizing the total deviation vector, providing a quantitative basis for determining the tilt direction of the standard arc module 1 in the subsequent process.

[0042] According to the above technical solution, after the standard arc module 1 is hoisted onto the adaptive positioning base 2, the system starts to continuously monitor the data of three contact pressure sensors on the outer wall of the conical positioning column 20. Once it is detected that the difference in the values of the three sensors of any conical positioning column 20 exceeds 5%, the system immediately starts the process of establishing the pressure deviation vector model. First, the azimuth angles of the three sensors in the cylindrical coordinate system are determined, which are 0°, 120°, and 240° respectively. Then, the pressure values P1, P2, and P3 of the three sensors are collected in real time. According to the trigonometric function relationship, the radial and tangential values of the deviation components of each sensor are calculated. Finally, the radial deviation components are added to obtain the total radial deviation Σ△ρ, and the tangential deviation components are added to obtain the total tangential deviation Σ△γ. Based on these deviation values, the system can accurately determine the tilt direction of the standard arc module 1, providing data support for subsequent attitude adjustment.

[0043] According to the above technical solution, by establishing the pressure deviation vector model in the cylindrical coordinate system, the pressure data collected by the sensors can be accurately converted into specific vector deviations, providing a precise quantitative analysis of the tilt direction of the standard arc module 1. This enables the system to more accurately judge the attitude deviation of the module, thereby more precisely controlling the electric servo push unit for attitude adjustment, greatly improving the installation accuracy of the module and ensuring the splicing quality of the storage tank wall. The establishment of this model also realizes the rapid calculation and analysis of the module attitude deviation. The system can obtain the deviation vector from the pressure data within a short time and issue an attitude adjustment instruction in a timely manner, avoiding the cumbersome process of traditional manual measurement and analysis, shortening the installation time, and improving the overall installation efficiency. In addition, this solution also enhances the reliability and stability of the system. The quantitative deviation analysis makes the attitude adjustment more scientific and reasonable, reduces installation problems caused by inaccurate human judgment or untimely adjustment, and reduces potential safety hazards caused by installation errors during subsequent use, providing a strong guarantee for the long-term stable operation of the storage tank.

[0044] In one of the technical solutions, the pitch angle △β of the calculation module around the vertical axis of the standard arc module 1 is calculated from the amplitude of the total tangential deviation Σ△γ: △β = arctan(k1Σ△γ × L); the horizontal radial displacement deviation △d of the standard arc module 1 is determined by the sign and amplitude of the total radial deviation Σ△ρ: △d = k2 × Σ△ρ; where, L is the vertical distance from the top of the conical positioning column 20 to the center of gravity of the corresponding standard arc module 1, m; k1 is the angle conversion coefficient, with a value of 2.5×10 -4 m / N; k2 is the radial displacement conversion coefficient, with a value of 3×10 -5 m / N.

[0045] Through the establishment of a mathematical model, the above technical solution further converts the pressure deviation vector into specific angular and displacement deviations, realizing the precise quantitative analysis of the three-dimensional attitude of the standard arc module 1. First, the system uses the calculated total tangential deviation Σ△γ and total radial deviation Σ△ρ, combines the preset geometric parameters and conversion coefficients, and constructs a mathematical expression for attitude deviation. Among them, the calculation of the pitch angle △β is based on the total tangential deviation Σ△γ. Through the formula △β = arctanarctan(k1Σ△γ × L), the imbalance of the tangential force is converted into the rotation angle of the module around the vertical axis. k1 is the angle conversion coefficient (with a value of 2.5×10 -4 m / N), and L is the vertical distance from the top of the conical positioning column 20 to the center of gravity of the module. This parameter needs to be measured and determined before installation according to the actual size of the module. The horizontal radial displacement deviation △d is directly determined by the sign and magnitude of the total radial deviation Σ△ρ. Through the formula △d = k2 × Σ△ρ (k2 is the radial displacement conversion coefficient, with a value of 3×10 -5 m / N), the deviation of the radial force is linearly mapped into the horizontal displacement of the module. These two formulas convert the electrical signals of the pressure sensors into displacement control parameters that can directly drive the actuator, providing a quantitative basis for the precise adjustment of the electric servo jacking unit.

[0046] According to the above technical solution, after the standard arc module 1 is hoisted to the adaptive positioning base 2 and the initial positioning is completed, the system uses the calculated total tangential deviation Σ△γ and total radial deviation Σ△ρ, and then calculates the pitch angle △β and the horizontal radial displacement deviation △d according to the mathematical model provided by the present invention. Subsequently, the system converts △β into the telescopic stroke difference of the two electric servo jacking units on both sides. After adjustment, the pressure data is collected in real time. If the difference between the newly measured values of the three sensors drops below 3%, the current attitude is locked; if it still exceeds the limit, the above calculation process is repeated until the deviation meets the requirements. The whole process forms a precise adjustment cycle of closed-loop control through real-time data acquisition, mathematical model calculation and actuator feedback. Through the establishment of the mathematical model, the precise mapping from pressure deviation to attitude deviation is realized. First, by introducing the geometric parameter L and the conversion coefficients k1 and k2, the abstract pressure imbalance is converted into specific angle and displacement deviations, enabling quantitative control of the attitude adjustment of the standard arc module 1 and avoiding the blindness of traditional empirical adjustment. Second, based on the independent calculation of △β and △d, the system can accurately compensate for the pitch tilt and radial offset of the module respectively. For example, when Σ△γ is positive, the module is driven to tilt backward, and when Σ△ρ is negative, the module is driven to contract inward, ensuring the directionality and effectiveness of the three-dimensional attitude adjustment, reducing ineffective actions, and shortening the single-module adjustment time to the minute level. Third, by precisely controlling the module attitude, the force balance degree of the three sensors of each conical positioning column 20 is guaranteed, effectively reducing the additional bending moment and shear stress of the connecting bolts, effectively improving the fatigue life of the bolts, and at the same time avoiding the excessive misalignment of the welding seams caused by the inclination of the standard arc module 1, fundamentally improving the sealing performance and structural durability of the storage tank wall, and providing a safer technical guarantee for high-risk medium storage scenarios.

[0047] In one of the technical solutions, according to the pitch angle deviation △β and the geometric parameters of the standard arc module 1, the telescopic stroke difference △S of the two electric servo jacking unit groups in the same group is calculated: △S = 2Lsin△β / D; According to the horizontal radial displacement deviation △d, the synchronous telescopic amount △X of the two electric servo jacking units in the same group is calculated: △X = △d / cosλ; Wherein, D is the horizontal distance between the two electric servo jacking units in the same group, in m; λ is the angle between the telescopic direction of the electric servo jacking unit consistent with the synchronous telescopic direction in the two electric servo jacking units in the same group and the horizontal plane, and λ≤10°.

[0048] The above technical solution converts the posture deviation (pitch angle deviation △β and horizontal radial displacement deviation △d) into specific control parameters of the electric servo push unit through geometric relationship modeling, so as to realize the precise adjustment of the three-dimensional posture of the standard arc module 1. First, the system calculates the pitch angle deviation and the horizontal radial displacement deviation, and then calculates the telescopic stroke difference of the two push units in the same group and the synchronous telescopic amount of the two electric servo push units in the same group. Among them, when calculating the telescopic stroke difference of the two push units in the same group, due to the extremely small pitch angle deviation, sin△β is approximately the radian value, so that the telescopic stroke difference of the two push units in the same group is accurate to the micron level. When calculating the synchronous telescopic amount of the two electric servo push units in the same group, the decomposition effect of the angle on the displacement is eliminated by cosine compensation. The abstract posture deviation is converted into specific action instructions for the push unit to ensure the precise mapping of mechanical adjustment and data solution.

[0049] The above technical solution realizes the full closed-loop precision control of data measurement-model calculation and mechanical execution. Through the independent calculation of the telescopic stroke difference of the two electric servo push units in the same group and the synchronous telescopic amount of the two electric servo push units in the same group, the pitch angle and radial displacement deviation are precisely controlled to ensure the extremely small joint error of the adjacent standard arc modules 1, fundamentally avoiding the risk of welding leakage caused by posture deviation. λ≤10° makes the vertical component of the push unit almost all drive force scope horizontal adjustment, greatly shortening the time of a single adjustment, and no manual intervention is required, which is suitable for 24h continuous construction. By precisely controlling the telescopic amount of the push unit, the matching clearance between the conical positioning hole at the bottom of the standard arc module 1 and the positioning column is guaranteed to be less than 0.05mm, which improves the uniformity of the contact stress, can effectively reduce the imposed bending stress of the connecting bolts, and extend the service life of the connecting bolts. At the same time, it ensures the uniformity of the compression of the silicone rubber waterproof buffer layer, improves the overall waterproof performance of the tank wall, and is especially suitable for the installation of large tanks in harsh environments such as low temperature and high humidity.
