Abstract

This article is devoted to the issues of restoring the performance of fi re pressure hoses in a fi re when punctures, cuts and fi stulas occur. Failure of fi re pressure hoses in a fi re occurs due to mechanical damage during the laying of main and working lines. In this case, an increase in the working pressure in the bag system leads to the loss of extinguishing agents and the appearance of fi stulas, longitudinal and transverse breaks. This article offers a technical solution aimed at developing a new clamp design to restore the performance of a fi re pressure hose with a diameter of 55 mm when it is damaged: a puncture or cut. For this purpose, a three-dimensional model of the clamp was developed and its strength analysis was performed using the Autodesk Inventor computer-aided design system. This device will allow you to restore the supply of fi re extinguishing agents in the shortest possible time if the pressure hoses are damaged in a fi re.

利用现代研究方法开发新的夹具设计，以恢复压力消防软管的可操作性，并基于计算机建模评估其技术状况

本文主要研究火灾中发生刺穿、割伤和爆裂时如何恢复消防压力软管的性能。火灾中消防压力软管的失效是由于铺设主管线和工作管线时的机械损伤造成的。在这种情况下，袋式系统中工作压力的增加会导致灭火剂的损失，并出现气泡、纵向和横向断裂。本文提供了一种技术解决方案，旨在开发一种新的夹具设计，以恢复直径为55mm的消防压力软管在损坏时的性能:穿刺或切割。为此，开发了夹具的三维模型，并使用Autodesk Inventor计算机辅助设计系统进行了强度分析。本装置可在火灾中压力软管损坏的情况下，在最短时间内恢复灭火剂的供应。
