Abstract

The purpose of the study is to substantiate the technical requirements for a robotic complexdesigned to eliminate man-made emergencies associated with the need to eliminate fires. Theseemergencies can occur, first of all, in radiation and chemical accidents, as well as in accidents atfire and explosion hazardous facilities. The elimination of such emergencies, as a rule, is associatedwith an increased risk for firefighters and rescuers and requires the use of heavy equipment.The article proposes a campaign that involves considering two possible options for using the complex:when extinguishing a fire over an area in the modes of a single cycle with a transportablesupply of water and when extinguishing fires in a long-term fire extinguishing mode. At the sametime, it is proposed to consider the areal fire extinguishing rate and water consumption as the main indicators for assessing the effectiveness of the complex. Under the areal rate of fire extinguishing,it is proposed to understand as the ratio of the fire extinguishing area to the time. Waterconsumption during fire extinguishing is a single value for all links in a serial chain, in the form ofwhich a scheme for supplying water to a fire source can be represented. For the first option, theamount of water flow is sequentially calculated, which depends on the pressure that is created infront of the water shaft. This indicator primarily depends on such factors as the water pressuregenerated by the pump, the pressure loss in the hose line, the excess or decrease of the water barrelin relation to the pump. According to the results of calculations for each link, the obtainedindicators are summarized. For the second option, the capabilities of the robotic complex for longtermfire extinguishing involve the use of an existing reservoir of natural or artificial origin as asource of fire extinguishing agent. At the same time, the number of factors affecting the areal rateof fire extinguishing and water consumption increases significantly. To simplify the calculations, anomogram has been developed that allows you to calculate not only the above indicators, but alsodetermine the predicted values of the time required to extinguish the fire. The data obtained as aresult of the above calculations make it possible to finally realize the main task of the studies underconsideration, that is assessment of the capabilities of a promising complex of a robotic complexfor extinguishing fires at radiation-, chemical- and explosive objects. This problem is proposedto be solved by forming the technical forms of the RTK, which can be created to solve firesat the above objects, and then by a comparative assessment of their qualities.
