In high-risk environments such as industrial production and power supply, explosive-proof inspection robots have become indispensable due to their excellent safety performance and automation capabilities. By replacing humans in dangerous areas for inspections, these robots greatly reduce safety risks. However, a major challenge that these robots face in their application is efficient charging. Traditional wired charging methods present numerous inconveniences in hazardous environments, while wireless charging technology, due to its convenience, has become a hot topic of research and application. Despite this interest, the application of wireless charging technology in explosive-proof inspection robots still faces multiple challenges and difficulties.

The primary issue for wireless charging technology in explosive-proof robots is efficiency. The energy transfer efficiency of wireless charging is limited by the transmission distance and precision of device alignment. For inspection robots, the mobility and unpredictability of their working environments make it difficult to maintain the optimal distance and angle for effective transmission. To ensure that inspection robots can acquire sufficient energy within limited charging times, it is crucial to improve the energy transfer efficiency of the wireless charging system during the design process. This goal can be achieved by optimizing the design of energy transfer coils and enhancing the alignment capabilities of the devices.

Deploying charging equipment represents another significant technical bottleneck. Inspection robots need to move freely in various harsh environments, and the arrangement of charging stations must fully consider the movement trajectories and environmental constraints of the robots. This not only involves the strategic placement of charging points but also requires the development of adaptable charging systems to fit different working scenarios. For instance, in environments that may contain explosive gases or dust, the durability and safety of charging equipment must be enhanced to ensure safe operation under extreme conditions. Additionally, temporary halts or path changes during inspection tasks require that the charging equipment can quickly respond and charge efficiently, posing higher demands on the system’s intelligence.

The impact of environmental interference on wireless charging should not be underestimated. In complex industrial settings, various electromagnetic interferences, changes in temperature and humidity, and mechanical vibrations can all reduce wireless charging efficiency. Explosive-proof inspection robots often work in areas with potential explosive hazards, so their wireless charging systems must have strong anti-interference capabilities to ensure stable and reliable energy supply under these harsh conditions. Therefore, wireless charging equipment design must thoroughly consider environmental adaptability, using protective and filtering technologies to boost resistance to environmental changes.

Safety is a crucial factor for any explosive-proof equipment, especially in wireless charging processes involving high power transmission. The safety of electromagnetic radiation and the overall explosive-proof performance of the system are paramount. Rigorous electromagnetic compatibility testing is required, and every aspect of the charging process must have explosive-proof capabilities. This necessitates special material selections and design modifications, as well as comprehensive safety evaluations and ongoing monitoring of the entire charging system.

Cost-effectiveness and operational convenience are also significant factors affecting the promotion and application of wireless charging. The high cost of current wireless charging devices may hinder widespread adoption, while the long-term durability and operational convenience directly influence return on investment for enterprises. Thus, when designing wireless charging solutions, it is crucial to lower manufacturing and maintenance costs without compromising charging performance and safety, such as through technological innovation and large-scale production to optimize resource allocation.

Despite these challenges, the prospects for wireless charging technology in the field of explosive-proof inspection robots remain promising. As technology continues to advance, particularly in terms of energy transmission efficiency, safety, and environmental adaptability, explosive-proof inspection robots will be able to operate more efficiently and safely. In the future, as industrial intelligence progresses, wireless charging technology will offer new possibilities for explosive-proof inspection robots, further driving industry advancement and development.
