Description

Technical Field

[0001] This invention belongs to the technical field of modular manufacturing of complete sets of lightning protection and grounding equipment, rapid construction of prefabricated lightning protection, and standardized components integrating multiple patented technologies. Specifically, it involves a standardized complete set of lightning protection and grounding equipment and assembly process that integrates multiple types of passive lightning protection and grounding core patented technologies, universal modular prefabrication for all scenarios, rapid assembly without welding, and layered protection. It is mainly used to integrate mass-produced distributed current distribution units, graphite grounding bodies, steel-copper transition joints, frozen soil insulation and resistance reduction modules, non-metallic isolation components, and other core components to realize standardized prefabrication, modular assembly, and industrialized mass implementation of lightning protection and grounding projects in multiple scenarios. It is widely applicable to lightning protection and grounding construction scenarios in computer rooms, mountains, frozen soil, ancient buildings, and steel structures. Background Technology

[0002] At present, lightning protection and grounding projects generally adopt the traditional construction mode of supplying scattered components, custom processing on site, and manual welding and assembly. A standardized, modular, and complete prefabrication and assembly system has not yet been formed, which cannot meet the needs of large-scale, industrialized, and multi-scenario batch engineering implementation and has many inherent technical and construction defects in the industry.

[0003] The existing lightning protection grounding construction system suffers from four major shortcomings: First, components are scattered and lack standardization. Various grounding components are supplied independently with inconsistent specifications, requiring extensive cutting, grinding, welding, and custom processing on-site. This results in cumbersome construction procedures, long work cycles, and high reliance on manual labor. Second, the system lacks versatility. Traditional grounding components are not specifically designed for different scenarios, such as conventional grounding in computer rooms, high-resistivity mountainous terrain, frozen soil environments, low-disturbance construction of ancient buildings, and steel structure buildings. Different working conditions require separate design and processing, making them non-interchangeable. Third, on-site construction quality is uncontrollable. Core connection points rely on manual welding, leading to inconsistent welding processes, frequent instances of incomplete or missing welds, resulting in large fluctuations in connection resistance, poor grounding stability, and a high risk of corrosion, disconnection, and grounding failure over long-term operation. Fourth, there is no standardized assembly process. Various lightning protection patented technology components are assembled piecemeal without unified construction specifications, hindering the integration and implementation of multiple patented technologies. This low level of standardization and industrialization severely restricts the large-scale, mass-production application of new lightning protection patented technology systems.

[0004] In summary, existing lightning protection grounding devices and construction processes suffer from technical bottlenecks such as non-standardized components, complex construction procedures, unstable welding quality, poor adaptability to different scenarios, and inability to be mass-produced and industrialized. The industry urgently needs a complete set of passive lightning protection grounding devices and standardized assembly processes that are modularly prefabricated across the entire spectrum, can be assembled quickly without welding, can be adapted to different scenarios, and provide long-term protection. Summary of the Invention

[0005] I. Purpose of the invention.

[0006] Addressing the technical shortcomings of existing lightning protection and grounding components, such as scattered and non-standard components, large on-site processing volume, unstable welding quality, poor versatility for various scenarios, and inability to integrate patented technologies for mass production, this invention provides a full-spectrum passive lightning protection and grounding modular rapid assembly device and assembly process. Through four core innovations—a full-spectrum universal modular component library, a weld-free clamping conductive assembly structure, scenario-adaptive complete kits, and a layered isolation and sealing integrated protection structure—this invention achieves standardized factory prefabrication of lightning protection and grounding components, rapid on-site modular assembly, precise adaptation to multiple scenarios, and integrated implementation of multiple patented technologies. This significantly shortens the construction cycle, unifies construction quality, and enables mass production and industrialization across all working conditions.

[0007] II. Technical Solution.

[0008] To achieve the above-mentioned objectives, the present invention adopts the following technical solution.

[0009] A full-spectrum passive lightning protection grounding modular rapid assembly complete set of equipment includes a universal modular component library, a weld-free crimping conductive latch assembly, scenario-specific complete kits, and a layered isolation integrated sealed protective shell. The universal modular component library integrates multiple patented core components for lightning protection, achieving standardized prefabrication and universal interchangeability of all components. The weld-free crimping conductive latch assembly replaces traditional on-site welding, achieving rapid conductive assembly without open flame and eliminating contact resistance deviations. The scenario-specific complete kits are standardized and configured for different geological and construction conditions, achieving one-click adaptation to different scenarios. The layered isolation integrated sealed protective shell, through a multi-layer composite structure, simultaneously achieves multiple long-term protections including heat preservation, insulation, corrosion resistance, and weather resistance.

[0010] Furthermore, the universal modular component library integrates standardized prefabricated components such as distributed current distribution units, graphite flexible grounding modules, dissimilar metal anti-corrosion transition joints, frozen soil insulation and slow-release resistance reduction modules, and non-metallic isolation components. All modules are of uniform specifications and mass-produced in a standardized manner. The components can be freely combined and interchanged. They can be assembled as needed to achieve multiple lightning protection functions such as layered equipotentiality, distributed current balancing, local impedance compensation, and shallow low-disturbance grounding.

[0011] Furthermore, the non-fusion-bonding conductive locking assembly has a built-in conductive paste sealing and pressing structure, which can accurately lock various connection points of pile foundation steel bars, steel structures, copper busbars, and grounding modules. It achieves stable surface contact and conduction through mechanical high-strength pressing, replacing the traditional on-site steel bar fusion and hot welding process, reducing the risk of contact resistance fluctuations caused by incomplete or disconnected connections, and improving connection accuracy, conduction stability, and assembly efficiency.

[0012] Furthermore, the scenario-specific complete kits are divided into four categories of standardized finished kits: computer room three-level equipotential bonding kits, mountain pile foundation reusable grounding kits, frozen soil impedance insulation and compensation kits, and ancient building shallow low-disturbance kits. These kits are precisely adapted to the normal working conditions of computer rooms, high-resistivity geological conditions in mountains, frozen soil freeze-thaw conditions, ancient building and cultural relic protection conditions, and steel structure building conditions. No secondary design on site is required, and the project geology and construction scenario can be matched with one click.

[0013] Furthermore, the layered isolation integrated sealed protective shell adopts a three-layer composite structure design, with an inner layer of high conductivity adapter layer, a middle layer of heat insulation / insulation isolation layer, and an outer layer of corrosion-resistant and weather-resistant protective layer. It can simultaneously meet the triple protection requirements of antifreeze and heat insulation in frozen soil scenarios, anti-electrochemical corrosion in ancient building scenarios, and anti-aging and weather-resistant in outdoor open-air scenarios, greatly improving the service life of the entire grounding device.

[0014] III. Assembly process steps.

[0015] S1. Conduct on-site surveys to verify site geological conditions, soil parameters, building types and construction conditions, match corresponding standardized grounding kits according to the scenario type, and complete the standardized configuration of the construction plan.

[0016] S2. The non-fusion-welding pressure-clamping conductive locking assembly is used to mechanically crimp and assemble the connection points of the pile foundation reinforcement, steel structure frame, and grounding module. No on-site hot welding is required, which can quickly complete the stable conductive connection of each node and eliminate the hidden dangers of poor connection and contact resistance deviation.

[0017] S3. Assemble the protective structure according to the corresponding scenario. For frozen soil conditions, add a middle layer of thermal insulation and isolation structure. For ancient building conditions, add a non-metallic insulation and isolation layer. For outdoor conditions, strengthen the outer anti-corrosion and weather-resistant shell to complete the layered isolation integrated sealing and protection assembly.

[0018] S4. In accordance with standardized assembly specifications, complete the series and parallel combination assembly of distributed current distribution units, passive impedance compensation modules, transition joints, and non-metallic isolation components to quickly build a full-area hierarchical equipotential and distributed current balancing grounding network.

[0019] S5. A complete set of grounding modules is laid out using a shallow narrow trench pre-buried method, filled with matching environmentally friendly resistance-reducing materials, and the soil contact performance is optimized to complete the equipotential closed-loop grounding construction of the entire site.

[0020] S6. Conduct full-line continuity testing and precise grounding resistance detection to verify the connection stability and grounding parameter compliance of each node. The entire device does not require secondary cutting or processing on-site and can be directly accepted and delivered after passing the test.

[0021] IV. Beneficial Effects.

[0022] Compared with the traditional scattered lightning protection and grounding construction system, this invention has outstanding novelty, creativity and practicality, and has four core beneficial effects.

[0023] First, this invention enables standardized factory prefabrication and mass production of core lightning protection components across the entire spectrum, completely eliminating the cumbersome processes of on-site cutting, grinding, welding, and custom processing. All components are modularized, standardized, and universal, requiring only assembly on-site, thus shortening the overall construction period and making it suitable for large-scale, batch industrialized engineering projects.

[0024] Secondly, the present invention adopts a fire-free clamping and locking assembly process to replace the traditional on-site welding operation, thereby avoiding the fire risk of fire on the construction site from the source. At the same time, it solves the problem of contact resistance fluctuation caused by differences in manual welding process. The conductivity consistency and stability of each connection node are better than the traditional manual welding process, and the reliability of the grounding system is greatly improved.

[0025] Third, this invention is equipped with four standardized scenario kits, which fully cover all application scenarios such as computer rooms, mountains, permafrost, ancient buildings, and steel structures. It can be adapted to the integration and implementation of lightning protection patent pool technologies, realize the systematic, complete, and industrialized batch application of multiple patent technologies, and build a standardized prefabricated lightning protection construction system.

[0026] Fourth, this invention adopts a three-layer layered isolation integrated composite protective shell, which simultaneously solves multiple industry problems such as low-temperature freeze-thaw failure in permafrost, electrochemical corrosion of dissimilar metals in ancient buildings, and long-term oxidation and aging outdoors. It achieves long-term stable protection under multiple extreme working conditions, reduces the cost of later operation and maintenance and replacement, and is suitable for the construction needs of various high-risk, complex and high-standard lightning protection and grounding projects.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to specific embodiments.

[0036] This invention discloses a full-spectrum passive lightning protection grounding modular rapid assembly device and assembly process. Relying on a standardized modular component library, a weld-free crimping assembly structure, scenario-specific complete kits, and a multi-layer composite protection structure, it enables rapid assembly, standardized construction, and integrated implementation of multiple patented technologies for lightning protection grounding projects in all scenarios. It is applicable to various civil, industrial, new energy, and cultural heritage building lightning protection grounding projects.

[0037] In the specific implementation process, the first step is to select and match complete sets of kits based on the on-site working conditions of the project. For ordinary computer room scenarios, a three-level equipotential complete set of kits is selected; for mountainous high-resistivity geological scenarios, a pile foundation reusable grounding kit is selected; for high-altitude and cold permafrost areas, a permafrost insulation impedance compensation kit is selected; for ancient building and cultural heritage protection scenarios, a shallow low-disturbance special kit is selected; and for steel structure building scenarios, steel structure building compatible parts are selected. This achieves precise adaptation to the scenarios from the source, eliminating the need for separate design and customization.

[0038] All grounding core components are prefabricated in a standardized factory, including distributed current distribution units, graphite flexible grounding electrodes, corrosion-resistant transition joints, frozen soil insulation modules, and non-metallic isolation components. All modules have uniform specifications and universal interfaces, allowing for free splicing and combination. On-site construction abandons traditional open-fire welding processes, employing specialized conductive clamping and locking components. Mechanical compression is applied at rebar connections, steel structure joints, and module joints, combined with built-in sealing conductive paste to achieve stable surface contact and conductivity, eliminating problems such as incomplete connections, missing connections, and oxidation-induced contact resistance drift. Construction is safe, efficient, and free of open flame risks.

[0039] The protective shell is assembled in different layers according to different scenarios. In the frozen soil scenario, a middle insulation structure is used to suppress the impedance change and equipment failure caused by soil freeze-thaw. In the ancient building scenario, a non-metallic isolation insulation layer is used to block the electrochemical corrosion channel of foreign metals and protect the safety of the foundation structure of ancient buildings. In the outdoor open-air scenario, a thickened anti-corrosion and weather-resistant outer layer is used to resist rainwater, salt spray and oxidation aging erosion.

[0040] Following standardized processes, multiple modules are connected in series and parallel to construct a hierarchical equipotential network, a distributed current shunt balancing network, and a local impedance compensation system, achieving the integrated implementation of multiple patented technologies. A shallow, narrow trench method is used to pre-bury the modular grounding device, filling it with environmentally friendly resistance-reducing materials to optimize soil contact performance, thus constructing a globally low-impedance, highly balanced, and highly stable grounding closed-loop system.

[0041] After construction is completed, full-line electrical continuity testing and grounding resistance verification are conducted. Once all parameters meet the standards, the system can be directly accepted and delivered without the need for on-site secondary processing, rectification, or repair. Construction quality is uniform, controllable, and traceable. The entire system is adaptable to long-term stable operation under all working conditions, offers comprehensive protection, and has an extended service life, meeting the construction standards and quality requirements for industrial-scale deployment.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
