Description

Technical Field

[0001] This utility model belongs to the technical field of container inspection equipment, and in particular relates to a container dustproof inspection chamber. Background Technology

[0002] The development of containers is an evolutionary history that has continuously improved the efficiency of global trade and logistics. Its journey began with standardization in the 1950s, when the unified specifications established by the International Organization for Standardization (ISO) enabled global multimodal transport, significantly reducing costs and becoming a key driver of globalization. Subsequently, the pursuit of economies of scale through larger ships (exceeding 24,000 TEU) and port automation led to a diversification of container types, resulting in specialized containers such as refrigerated containers and open-top containers. Current development has entered a stage of intelligent and green development, with smart containers integrating Internet of Things (IoT) sensors enabling real-time monitoring of cargo location and status, while material innovation and environmentally friendly design are also key focuses. The future is moving towards a deep integration of digitalization, automation, and sustainability.

[0003] Equally important as container transport capacity is its protective performance, especially dustproof sealing, which directly relates to the safety of high-value goods such as precision instruments and electronic products. Existing dustproof detection methods are diverse, and their evolution reflects the industry's pursuit of precision. Traditional methods mainly rely on visual inspection and light testing, which are simple but highly subjective and cannot detect minute leaks. Water flushing tests simulate heavy rain environments and are currently a very common on-site detection method, but they are time-consuming, water-intensive, and cannot be quantified. Dust testing (talc testing) is suitable for water-sensitive environments and can show the path of dust intrusion, but it also cannot be quantified. A more advanced and objective method is differential pressure testing (negative pressure testing), which uses specialized equipment to create negative pressure inside the container and monitors the rate of pressure decay to quantify the sealing level. It is efficient and accurate and is widely used by large manufacturers and leasing companies. The most precise method is ultrasonic testing, which can accurately locate extremely small leaks, but the equipment is expensive and is mostly used for precision inspections. Overall, container dustproof detection technology is evolving from traditional methods relying on experience to advanced, data-driven, and quantifiable methods to meet the higher requirements of the high-end logistics market for supply chain security. The prior art uses a dustproof detection device based on patent application number CN202220887998.1, entitled "Dustproof Detection Component and Container Detection Device for Container Inspection." This device includes a housing with a window penetrating one side wall; a detection probe housed within the housing and scanning the container through the window; a rotatable block housed within the housing; and a rotation drive assembly housed within the housing and used to drive the rotating block to rotate. During rotation, the rotating block is used to close or open the window. By driving the rotating block to open the window, the detection probe emits a laser that can exit through the window to inspect the container. Conversely, by driving the rotating block to close the window, the detection probe is isolated from the outside environment when not in operation, effectively reducing the entry of external dust into the detection probe and providing dustproof protection.

[0004] However, using existing container dust inspection equipment to inspect containers presents limitations due to the large size of the containers. Utility Model Content
