[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See also Figure 3 The present invention provides a technical solution, a method for assembling a steel structure iron tower that is easy to assemble quickly, comprising the following steps: S1, design and produce prefabricated modules; design and produce prefabricated module units according to the structural requirements of the target tower; the module units include triangular or polygonal steel frames, using corrosion-resistant steel with a tensile strength of 400-600 MPa and a thickness of 10-20 mm; the module units are designed to integrate cable channels with a width of 50-100 mm and a channel wall thickness of 5-10 mm to ensure the safe arrangement of cables and transmission lines, thereby obtaining prefabricated module units; S2, conduct an environmental impact assessment on the prefabricated module unit; based on the material and structural characteristics of the prefabricated module unit, analyze the climate and geographical characteristics of the target installation site, including strong winds with a wind speed of 10-30 m / s, extreme temperatures ranging from -40°C to +50°C, and humidity conditions ranging from 10% to 90%; based on the assessment results, optimize the design of the prefabricated module unit to enhance stability and durability under extreme weather conditions, and obtain an optimized prefabricated module unit; S3, carry out integrated design of cables and transmission lines; in the optimized prefabricated module unit, design the position and size of the cable channel so that the channel can accommodate cables and transmission lines with a diameter of 10-50 mm; adjust the layout of the channel to minimize the cable layout path, reduce the bending radius, ensure the transmission efficiency and life of the cable, and obtain the prefabricated module unit with integrated cable channel; specifically, in step S1, the design and production of prefabricated module units involve refined engineering technology and specific operations. First, according to the specific structural requirements of the tower, professional design software is used for modular design. The design team will draw detailed engineering drawings, including the size of the triangular or polygonal steel frame, the structural connection points, and the necessary supporting components. Next, select suitable corrosion-resistant steel with a tensile strength of 400-600 MPa and a thickness of 10-20 mm to ensure the firmness and durability of the structure. High-precision laser cutting technology is used in the steel cutting process to ensure cutting accuracy and smooth edges to avoid stress concentration in the material during subsequent processing. The welding process uses automated welding equipment, and strict weld inspection is used to ensure that the welding quality meets the engineering requirements. In addition, the cable channel integrated in the modular unit design requires a corresponding space to be reserved on the steel frame, and a steel plate with a thickness of 5-10 mm is used to process the channel to ensure the safe layout of cables and transmission lines. Finally, through assembly simulation and quality inspection, the dimensional accuracy and structural integrity of each prefabricated modular unit are ensured to complete the production of the prefabricated modular unit.

[0018] In step S2, the environmental impact assessment of the prefabricated module unit includes a comprehensive analysis of the weather resistance and adaptability of the module unit. The assessment team first collects data on the climate and geographical characteristics of the target installation site, including parameters such as wind speed, temperature and humidity, and then performs finite element analysis on the structure to determine which areas are prone to failure due to stress concentration, and increases the thickness of the steel by 10%-20% in these areas to improve the strength. After design optimization based on the assessment results, the simulation test is re-performed to verify the optimization effect. To ensure that the module unit can withstand various pressures in the actual working environment, and finally form an optimized prefabricated module unit, this step will generate a detailed environmental adaptability report to provide a scientific basis for subsequent construction.

[0019] In step S3, the integrated design of cables and transmission lines is carried out. This process requires precise planning of the layout and size of the cable channels. The design team conducts detailed channel layout design based on the optimized module units to ensure that the location of each channel can meet the diameter and length requirements of the cables and transmission lines. Through advanced design software, three-dimensional simulation is carried out to check whether the cable channel conflicts with the module structure, and the channel position is adjusted to achieve intuitive wiring and the shortest path. The design considers reducing the bending radius to reduce the loss of the cable during use and improve the transmission efficiency. After the design is completed, a detailed cable layout diagram and installation guide are generated. These documents will be used to guide on-site construction personnel to correctly install cables and transmission lines, ensure the smooth progress of the overall construction, and improve the signal transmission efficiency and operation safety of the entire tower system.

[0020] S4, preparation stage; prepare the tools and equipment required for assembly, including lifting equipment with a rated lifting capacity of 10-30 tons, electric wrenches with a torque range of 100-500 Nm, and auxiliary tools; conduct quality inspection on the prefabricated module units with integrated cable channels, check that the dimensional tolerance is within ±1 mm, and there are no cracks and defects in the welding parts, and obtain qualified prefabricated module units and assembly equipment; S5, conduct module unit quality inspection on qualified prefabricated module units and assembly equipment; use ultrasonic flaw detector to conduct non-destructive inspection on welding joints of prefabricated module units to ensure that there are no internal defects; measure the thickness of anti-corrosion coating to ensure that the coating thickness is between 100-200 microns to meet the anti-corrosion requirements; verify that the inner wall of the cable channel is smooth and burr-free, and obtain prefabricated module units that meet the quality requirements; S6, integrate sensor and camera design in prefabricated module units that meet quality requirements; design and install interfaces for multi-directional cameras and environmental sensors in the module units according to monitoring requirements; the camera installation interface is suitable for equipment with a diameter of 50-100 mm, and the sensors include temperature, humidity and wind speed sensors, and the interface voltage is 12-24 volts; ensure that the sensors and cameras can cover the 360-degree range around the tower, and obtain prefabricated module units with integrated sensor and camera interfaces; Specifically, in step S4, the preparation phase involves the preparation of the tools and equipment required for assembly and the preliminary inspection of the prefabricated module units. The team will make a detailed list of the required equipment, including 10-30 tons of lifting equipment, 100-500 Nm electric wrenches and other auxiliary tools to ensure that these equipment can meet the construction needs. After the selected equipment is collected from the supplier and transported to the construction site, the technicians responsible for equipment management will conduct a series of functional tests on these equipment to confirm that they are in good operating condition and have no safety hazards. At the same time, the technical team conducts strict quality inspections on the prefabricated module units, including precise measurement of dimensional tolerances to ensure that they are within ±1 mm, and the use of professional testing equipment to inspect the welding parts to ensure that there are no cracks and defects. The completion of this stage lays a solid foundation for the subsequent assembly work, and generates equipment inspection reports and module unit qualification certificates. These documents will be used to ensure the smooth progress of the construction process and avoid construction delays caused by equipment failure or module quality problems.

[0021] In the S5 step, an in-depth quality inspection of the prefabricated module units is carried out to ensure that the module units meet all engineering and safety standards. The quality inspection team uses ultrasonic flaw detectors to perform non-destructive testing on all welded joints to ensure that there are no internal defects in the welds, thereby ensuring the stability and long-term durability of the structure. The thickness measurement of the anti-corrosion coating is completed by a dedicated instrument. The measurement results ensure that the coating thickness is between 100-200 microns, which meets the anti-corrosion requirements. In addition, the inner wall of the cable channel is also inspected in detail to confirm that there are no burrs to prevent cable damage. Through these detailed inspection processes, a quality inspection report is generated, which records the test data and evaluation results in detail. These reports not only provide confirmation of the quality of the module units, but are also important documents for subsequent approval and file retention to ensure the reliability of construction and long-term operation and maintenance.

[0022] In step S6, the prefabricated module units are designed with integrated sensors and cameras to meet the monitoring needs of the tower. The design team accurately planned the installation locations and interfaces of the cameras and sensors based on the specific layout and functional requirements of the module units. The camera installation interface design allows devices with a diameter of 50-100 mm to be firmly installed, while temperature, humidity and wind speed sensors are configured in key locations to ensure that environmental data can be monitored and recorded. Circuit design experts ensure that the voltage adaptability of all interfaces is between 12-24 volts and is compatible with various monitoring devices. Through this design, the tower can achieve 360-degree monitoring of the surrounding environment without blind spots, enhancing security monitoring capabilities. This step generates detailed installation and wiring drawings, which will guide field engineers to correctly install sensors and cameras to ensure the normal operation of the equipment and long-term monitoring effects.

[0023] S7, assemble the prefabricated module units with integrated sensors and camera interfaces into structural blocks; select the corresponding number of module units according to the designed height and structure of the tower; use high-strength bolts for connection, with bolt specifications of M20-M30 and torque of 200-400 Nm; quickly splice the module units to ensure that the verticality error of the connection parts is within 1‰, and obtain the preliminarily assembled tower main structure; S8, horizontally pre-assemble and calibrate the preliminarily assembled tower main structure; place the tower main structure horizontally, and use a laser rangefinder and a level to measure the size and shape and position tolerances of the tower main structure; adjust the parts that do not meet the requirements so that the overall verticality deviation does not exceed 1‰ and the horizontality deviation does not exceed 0.5‰, and obtain the calibrated tower main structure; S9, waterproof and anti-corrosion treatment is performed on the main structure of the tower after correction; waterproof sealant is applied to the joints and welding parts of the tower with a thickness of 1-2 mm; weather-resistant anti-corrosion coating is sprayed on the whole structure to ensure that the anti-corrosion life reaches 15-25 years, and the main structure of the tower is waterproof and anti-corrosion treated; Specifically, in step S7, the prefabricated module units with integrated sensors and camera interfaces are assembled in structural blocks. The construction team selects an appropriate amount of prefabricated module units according to the design height and structural requirements. High-strength bolts with specifications of M20 to M30 are used for assembly, and the torque of the bolts is set between 200 and 400 Nm to ensure the stability of the structural connection. During the assembly process, technicians use advanced measuring tools, such as laser alignment instruments, to ensure that the verticality error of the connection parts of each module unit is controlled within 1‰. This precise adjustment not only ensures the uprightness and stability of the structure, but also provides a solid foundation for subsequent assembly work. After completing these operations, the main structure of the initially assembled tower is formed. The work results at this stage are reflected through detailed assembly records and structural inspection reports. These documents record the key parameters and results of the assembly process, providing a basis for subsequent review and quality assurance.

[0024] In step S8, the preliminarily assembled main structure of the tower is horizontally preassembled and corrected. The construction team first places the tower structure horizontally on the predetermined assembly platform. Strict dimensional and geometric tolerance measurements are performed using laser rangefinders and levels. For any deviations found during the measurement, the construction technicians will immediately make adjustments to ensure that the overall verticality deviation of the tower does not exceed 1‰ and the horizontality deviation does not exceed 0.5‰. The accurate execution of this step greatly improves the accuracy and overall stability of the structure. These adjustments ensure the geometric and structural integrity of the tower and form the corrected main structure of the tower. The results of this stage are recorded in the correction report, which lists the test data and adjustments in detail, which is of great significance to ensure the quality of the project.

[0025] In step S9, the main structure of the corrected tower is waterproofed and anti-corrosion treated. The construction team evenly applies waterproof sealant to the interfaces and welding parts of the tower, with a thickness of 1 to 2 mm to close potential tiny gaps and prevent moisture intrusion. Subsequently, the entire structure is sprayed with weather-resistant anti-corrosion paint to ensure that the coating is uniform and the thickness meets the design requirements. The coating operation at this stage not only enhances the anti-corrosion ability of the tower, but also extends the service life of the structure. The expected anti-corrosion life can reach 15 to 25 years. After completing these treatments, the main structure of the tower that has been waterproofed and anti-corrosion treated is obtained. The relevant operation records and quality inspection reports record in detail the materials, methods and results used, ensuring the long-term reliability of the treatment effect and providing a guarantee for the long-term stable operation of the tower.

[0026] S10, layout the cable channel and transmission line on the main structure of the iron tower that has been waterproofed and anti-corrosion treated; arrange the cables and transmission lines in the pre-designed cable channel according to the cable specifications and quantity; the cable fixing interval is 1-2 meters, and corrosion-resistant cable clamps are used; ensure that the cables are not excessively bent, and the bending radius is not less than 15 times the cable diameter, and obtain the iron tower structure with the cables and transmission lines arranged; S11, install sensors and cameras on the iron tower structure where the cables and transmission lines are arranged; install multi-directional cameras and environmental sensors at the reserved installation interface; the camera installation height interval is 10-20 meters, and the sensors are installed at different heights; connect the power supply and signal lines of the equipment to obtain the iron tower structure where the sensors and cameras are installed; S12, cleaning and preparing the installation base of the tower structure where the sensor and camera are installed; cleaning the debris and obstacles at the tower installation base, ensuring that the ground flatness is within ±5 mm; according to the tower foundation design, digging a foundation pit with a depth of 2-4 meters, pouring a concrete foundation with a strength of C30-C40, and the size meets the design requirements, to obtain a prepared tower installation base; Specifically, in step S10, the work of laying out the cable channel and transmission lines includes several detailed operation steps. First, according to the specifications and quantity of the cables and transmission lines, they are placed in the pre-designed cable channel. Technicians use corrosion-resistant cable clamps to fix each cable, maintaining a fixed spacing of 1 to 2 meters, which can protect the cables and facilitate future maintenance. During the wiring process, special attention is paid to the bending radius of the cable being no less than 15 times the cable diameter. This strict control avoids excessive bending of the cable, thereby reducing the risk of cable damage and signal attenuation. After completing these steps, the cable and transmission line tower structure is arranged, which provides the basis for the functionality and safety of the entire tower. The records and wiring drawings of this step will be used to guide subsequent review and maintenance work to ensure that all wiring meets design and safety standards.

[0027] In step S11, sensors and cameras are installed on the tower structure where cables and transmission lines are arranged. First, technicians install multi-directional cameras and environmental sensors at the reserved installation interfaces according to design requirements. Cameras are installed at intervals of 10 to 20 meters to cover different perspectives of the tower's surrounding environment, while sensors are arranged at different heights according to functional requirements to monitor environmental parameters such as temperature, humidity and wind speed. During the process of connecting the power supply and signal lines of the equipment, technicians ensure that all connections are stable and comply with electrical safety regulations. After this step is completed, a tower structure equipped with sensors and cameras is obtained. The functionality and operability of these devices will directly affect the effectiveness of the tower monitoring system. Detailed records of the installation process and system test reports provide accuracy and reliability guarantees for equipment installation.

[0028] In step S12, the installation base of the tower structure is cleaned and prepared. This includes removing all debris and obstacles from the tower installation base to ensure a clean and safe work area. Next, according to the tower foundation design requirements, use excavation equipment to dig a foundation pit with a depth of 2 to 4 meters. Ensure that the size and depth of the excavation strictly comply with the design drawings. After the excavation is completed, a concrete foundation with a strength of C30 to C40 is poured, and the flatness is controlled within ±5 mm to ensure the firmness and stability of the foundation. The completion of this stage forms a solid base suitable for tower installation. The detailed records of the preparatory work and the foundation quality report will support the smooth progress of the subsequent construction phase and ensure that the tower stands here stably for a long time.

[0029] S13, assemble the tower structure with the sensors and cameras installed vertically; use a crane with a lifting capacity of 50-100 tons to lift the main structure of the tower from a horizontal state to a vertical state; connect the bottom of the tower with the embedded foundation parts using high-strength bolts with specifications of M24-M36 and a torque of 300-600 Nm; ensure that the verticality deviation of the tower does not exceed 1‰, and obtain the installed tower; S14, install safety protection facilities on the installed tower; install anti-climbing frame on the outside of the tower; install lightning protection device, the height of lightning rod is 1-2 meters, and the grounding resistance is not more than 10 ohms; install bird repellent device, the interval is 5-10 meters, to avoid bird nesting; install anti-theft alarm, and obtain the tower with safety protection facilities installed.

[0030] S15, the iron tower with safety protection facilities installed is subjected to corrosion inhibition treatment; ultrasonic stirring equipment is used with a frequency of 20-40 kHz to spray a solution containing a nitrite rust inhibitor on the surface of the iron tower for 30-60 minutes to form a protective film to delay the corrosion process and obtain an iron tower that has completed the corrosion inhibition treatment.

[0031] S16, conduct system testing and adjustment on the iron tower that has completed the corrosion inhibition treatment; test the installed monitoring equipment and sensors, and check the transmission quality of the video signal and sensor data; adjust the angle of the camera to make sure there are no blind spots in the monitoring range; calibrate the sensor to ensure that the data accuracy error is within ±2%, and obtain the iron tower that has completed the test and adjustment.

[0032] S17, conduct final inspection and finishing of the tower after testing and adjustment; check the structure, equipment installation and protective facilities of the tower according to quality inspection standards; clean up the construction site, remove excess materials and equipment, and obtain the assembled steel structure tower.

[0033] Specifically, in step S13, the tower structure with sensors and cameras installed is assembled vertically. The construction team uses a crane with a lifting capacity of 50 to 100 tons to slowly lift the main structure of the tower from a horizontal position to a vertical state. During the lifting process, technicians monitor the position and posture of the tower in real time to ensure that its verticality deviation does not exceed 1‰. The connection between the bottom of the tower and the foundation uses high-strength bolts with specifications of M24 to M36, and the torque is controlled at 300 to 600 Nm to ensure the firmness and long-term stability of the connection. This operation ensures the correct installation and structural safety of the tower, and finally forms an installed tower. After this step is completed, installation records and structural stability reports are generated. These documents are important bases for tower delivery and subsequent maintenance.

[0034] In step S14, safety protection facilities are installed on the installed tower. The technical team installs anti-climbing frames on the outside of the tower to prevent unauthorized climbing. At the same time, lightning rods 1 to 2 meters high and grounding systems with a grounding resistance of no more than 10 ohms are installed to enhance the safety of the tower in lightning weather. In addition, bird repellent devices are installed every 5 to 10 meters to avoid equipment damage and signal interference caused by bird nesting. Anti-theft alarms are installed to improve security monitoring capabilities. Through these measures, the safety of the tower has been comprehensively improved, and the generated installation records and equipment function test reports prove the correct installation and effectiveness of the protection facilities.

[0035] In step S15, the iron tower with safety protection facilities installed is treated with corrosion inhibition. Using ultrasonic stirring equipment, the frequency is set at 20 to 40 kHz, and a chemical solution containing 5% to 10% corrosion inhibitor is sprayed on the surface of the iron tower. The treatment time is kept at 30 to 60 minutes, which can form a protective film on the surface of the iron tower, effectively delaying the corrosion process. This step not only improves the weather resistance of the iron tower, but also extends its service life. After completion, detailed treatment records and effect evaluation reports are generated, which provide a scientific basis for the long-term maintenance of the iron tower.

[0036] In step S16, the system test and adjustment of the tower after the corrosion inhibition treatment is completed are carried out. The technicians test the installed monitoring equipment and sensors, and check the transmission quality of the video signal and sensor data. At the same time, the camera angle is adjusted to ensure that there are no blind spots in the monitoring range. The sensors are precisely calibrated to ensure that the data accuracy error is within ±2%. Through these tests and adjustments, the functionality and reliability of the tower are ensured, and the tower after testing and adjustment is obtained. The generated test records and adjustment reports provide technical support for the official operation of the tower.

[0037] In step S17, the tower that has been tested and adjusted is finally inspected and sorted. According to the quality inspection standards, the structure, equipment installation, and protective facilities of the tower are comprehensively inspected. Clean up the construction site, remove excess materials and equipment, and keep the site clean. The work at this stage ensures that all functions of the tower are performed according to the design requirements and the overall quality of the tower meets the predetermined standards. After completing these tasks, the assembled steel structure tower is obtained. The relevant inspection reports and cleaning records not only prove the construction quality, but also provide necessary documentation support for the delivery and subsequent use of the tower.

[0046] w s =1.0m: The width of the steel frame, according to the structural design requirements, to ensure overall stability and bearing capacity.

[0047] Calculate the initial cross-sectional area: Calculate the correction factor k: The correction factor k is used to adjust the cross-sectional area, taking into account the effect of the cable channel on the strength of the steel frame structure. The calculation formula is: Substituting the known values ​​into: Calculate the square root: Get the correction factor: k = 1 + 0.2828 = 1.2828 Calculate the required cross-sectional area A: A=A 0 ×k=0.003m 2 ×1.2828=0.0038484m 2 The calculated cross-sectional area A≈0.00385m 2 , compared with the initial cross-sectional area A 0 =0.003m 2 This indicates that after considering the influence of the cable channel width, the cross-sectional area of ​​the steel frame needs to be increased to ensure the safety and reliability of the structure.2 , may not meet the strength requirements; and the cross-sectional area is greater than 0.00385m 2 This means that material utilization is reduced and costs are increased. This result shows that by accurately calculating the cross-sectional area, material usage can be optimized while meeting safety requirements.
