III. Technical Principles and Design

3.1 Structural Design

Overall Framework: The main frame is constructed from high-strength steel to ensure structural stability during transportation, handling, and exposure to external impacts. The frame design adheres to standard container dimensions, facilitating compatibility with existing transport and handling equipment. Key load-bearing components, such as corner fittings, bottom corner fittings, and primary load-bearing beams, are reinforced to enhance the overall load-carrying capacity.

Internal Layout: The facility is rationally zoned and arranged according to the types, dimensions, and frequency of use of stored weapons and ammunition. In the weapons storage area, dedicated weapon mounting racks, secure locking mechanisms, and cushioning pads are installed to ensure that weapons remain firmly in place and undamaged during storage and transport. In the ammunition storage area, different storage units are designated based on ammunition type and hazard level, equipped with appropriate ammunition racks, trays, and dividers to enable categorized storage and rapid retrieval. At the same time, passageways are strategically designed to facilitate personnel operations and material handling within the facility.

Modular Design Concept: The containerized weapons (ammunition) compartment is divided into multiple functional modules, including storage, protection, environmental control, and monitoring modules. After each module is prefabricated in the factory, they are rapidly assembled and commissioned on-site, thereby enhancing construction efficiency and reducing construction complexity. This modular design also facilitates subsequent maintenance, upgrades, and component replacement; when a particular module malfunctions or requires functional enhancements, it can be addressed independently without disrupting overall system operation.

3.2 Material Selection

Container Material: The main body of the container is fabricated from high-quality, weather-resistant steel and undergoes surface anti-corrosion treatment, such as hot-dip galvanizing or application of anti-rust paint, to enhance its corrosion resistance under various climatic conditions. For containerized weapon (ammunition) compartments with higher protection requirements, special alloy steels or armored materials may be used to improve the container’s bulletproof and blast-resistant performance.

Internal protective materials: At the points of contact between weapons and ammunition and the container, materials with cushioning, shock-absorbing, and insulating properties—such as rubber pads and foam plastics—are used to prevent damage caused by vibration and impact during transportation, while also mitigating the risk of static electricity that could lead to safety incidents. In ammunition storage areas, certain sections may be lined with fire-resistant and flame-retardant materials to enhance fire safety.

Sealing Materials: To ensure a stable indoor environment and prevent the ingress of external dust, moisture, and harmful gases, high-performance sealing materials—such as silicone rubber seals and polyurethane sealants—are used at all joints and seams of the enclosure, as well as along door and window edges, to achieve excellent sealing performance and maintain the stability of the indoor microenvironment.

3.3 Functional Module Integration

Storage Function Module: This is the core functional module, which achieves orderly storage of weapons and ammunition through meticulously designed storage racks, pallets, and securing devices. The storage racks can be custom-made to accommodate the dimensions of various weapons and ammunition and are adjustable to meet the storage requirements of equipment and supplies of different specifications. For example, long-barreled weapons can be stored on dedicated gun racks that use hooks or slots for secure fixation, while artillery shells and other types of ammunition can be stored on tiered pallet-style racks, facilitating categorized storage and inventory management.

Environmental Control Module: Equipped with temperature and humidity control devices, such as air-conditioning units, dehumidifiers, and heaters, this module precisely regulates indoor temperature and humidity in accordance with the environmental requirements for storing weapons and ammunition, thereby preventing rust on weaponry and degradation of ammunition performance caused by fluctuations in temperature and humidity. In addition, a ventilation system is installed to facilitate regular air exchange, maintaining fresh indoor air and preventing the accumulation of harmful gases. For certain ammunition storage rooms with extremely stringent environmental requirements, air purification equipment may also be provided to filter out impurities and harmful constituents from the air.

Security Protection Module: Establishes a comprehensive security protection system from multiple perspectives. In terms of physical protection, measures such as reinforcing the enclosure structure and installing bullet-resistant doors and windows are implemented to withstand external attacks. For fire protection, fire alarm systems and automatic fire suppression devices—such as smoke detectors, dry powder extinguishers, and gaseous fire suppression systems—are installed, ensuring timely alerts and rapid extinguishment in the event of a fire. For explosion protection, explosion-proof electrical equipment is used, and pressure-relief devices are installed, including explosion-proof lights, switches, and ventilation openings, to prevent high-pressure surges from internal explosions from causing severe damage to the enclosure and the surrounding environment. For anti-theft protection, access control systems and surveillance cameras are deployed to monitor personnel entry and exit and indoor conditions in real time, thereby preventing the theft of weapons and ammunition.

Monitoring and Management Functional Module: Leveraging sensor technology, network communication technologies, and intelligent management software, this module enables real-time monitoring and remote management of indoor environmental parameters (such as temperature, humidity, and air quality), equipment operating statuses (including ventilation and air-conditioning systems), and security conditions (such as access-control status and intrusion alarms). Facility managers can use mobile devices or computers to view indoor conditions anytime, anywhere, receive alerts for abnormal events, and remotely control relevant equipment, thereby enhancing management efficiency and timeliness. For example, when temperature or humidity levels exceed preset thresholds, the system automatically activates air-conditioning or dehumidification equipment to restore optimal conditions and simultaneously sends an early-warning notification to management; similarly, if the access-control system detects an unauthorized entry, it immediately triggers an alarm and activates surveillance cameras in the affected area to record and collect evidence.
