Core Viewpoint - The article discusses the current limitations and challenges of using drones for firefighting, particularly in high-rise buildings, highlighting that the technology is still in its early stages and not yet ready for widespread practical application [2][11]. Group 1: Sales and Business Impact - The sales of firefighting drones are minimal, contributing very little to the overall revenue of companies involved in this sector. For instance, Helen Zhe has sold only three units of its first-generation firefighting drone [3]. - Other companies, such as Chen An Technology and Qing Niao Fire Protection, also report that their drone business has not yet generated significant revenue, with most of their focus still on traditional firefighting equipment [3]. Group 2: Technical Limitations - Current drone technology faces physical limitations in practical applications, particularly in high-rise firefighting scenarios. The existing drones struggle with the volume of water they can carry and the effects of high-pressure water flow [5][8]. - The predominant methods for firefighting using drones include "water delivery" and "fire extinguishing projectiles," but both have limitations in effectiveness against large fires [6][7]. Group 3: Environmental Challenges - High-rise fires present unique challenges due to turbulent airflow and strong winds, which require drones to have high power and stability to operate effectively [10]. - The article suggests that a coordinated approach using multiple drones may be necessary to tackle larger fires, as single units are insufficient [10]. Group 4: Future Directions - The industry needs to focus on developing a comprehensive framework for drone firefighting, including airspace management, collaborative command systems, and technical standards for high-capacity drones [11]. - There is a call for innovation and experimentation within the industry to fully realize the potential benefits of firefighting drones [11].

Core Viewpoint - The current state of drone technology for firefighting, especially in high-rise buildings, is still lacking in practical application and standardization, facing numerous technical and regulatory challenges [1][11]. Group 1: Current Market Situation - Sales of firefighting drones are low, contributing minimally to the overall revenue of companies involved in this sector [3]. - Companies like Helen Zhe (300201.SZ) have reported selling only three units of their first-generation firefighting drone, indicating a very small market presence [4]. - Other companies, such as Chen An Technology (300902.SZ) and Qingniao Firefighting (002960.SZ), also express that their drone business has not yet formed stable revenue streams and remains in the research and development phase [4][5]. Group 2: Technical Limitations - The current technical paths for firefighting drones have physical limitations, particularly in high-rise fire scenarios where traditional ground equipment has blind spots [5]. - The main methods of firefighting include "water-based extinguishing" and the use of fire extinguishing projectiles, with the latter being more common for smaller drones [6][7]. - Small drones face challenges in carrying sufficient extinguishing projectiles, while larger drones struggle with the weight of water hoses and the effects of air currents [8][9]. Group 3: Future Development and Challenges - The industry requires a comprehensive approach to address the challenges of high-rise firefighting, including the need for drone swarms to effectively combat large fires [9][10]. - There is a call for the establishment of a management system for airspace and a collaborative command structure to enhance the operational effectiveness of firefighting drones [11]. - The development of high-power firefighting drones and the integration of extinguishing agents with drone technology are critical areas that need attention for future advancements [11].
