Abstract
<jats:p>Статья посвящена проблеме прокладки рукавных линий при применении робототехнических средств пожаротушения. Проведен эксперимент по исследованию силы трения, возникающей при перемещении 100-метровой рукавной линии робототехнического средства, и оценке целесообразности использования 50-метровых рукавов для робототехнических комплексов пожаротушения. Анализ полученных результатов позволил количественно определить влияние рукавной арматуры, в частности полугаек, на величину силы трения, возникающей при прокладке пожарных напорных рукавов методом протяжки.</jats:p> <jats:p>This article examines the problem of laying hose lines when using robotic fire extinguishing systems to suppress fires. The challenges encountered during firefighting using robotic systems are analyzed. An experiment was conducted to determine the actual maximum throughput capacity of modern 20- and 50-meter-long fire pressure hoses (FPH). The problem of ensuring a continuous supply of fire extinguishing agents is examined using a specific example: extinguishing a fire at a military arsenal using FPHs. Without solving the problem of continuous supply of fire extinguishing agents, all other improvements in robotics will prove only a partial solution to the global problem of ensuring public safety. An analysis of scientific publications related to the need to clarify the key parameters of FPH traction forces and the frictional force encountered during the installation of fire pressure hoses made of modern materials using the pulling method demonstrates the high relevance of research conducted in this area. An experiment was conducted to study the friction force generated by moving a 100-meter robotic hose line and to evaluate the feasibility of using 50-meter hoses for a fire suppression system. Analysis of the obtained results allowed to quantify the impact of hose fittings, particularly half-nuts, on friction. Further research should be aimed at refining these data, taking into account various surface types, obstacles, and operating conditions, to ensure the development of a fire suppression system with optimal performance for any fire suppression scenario. Furthermore, it is necessary to consider the influence of various factors, such as ambient temperature, the presence of snow or ice, and soil type, on the amount of friction and the required traction force. Only a comprehensive approach that takes all these nuances into account will enable the creation of a truly effective and reliable water delivery system for fire suppression.</jats:p>
