MOBILE MEANS OF PROTECTING PEOPLE AGAINST FOREST FIRE

摘要

FIELD: rescue operations.;SUBSTANCE: invention relates to technical means of saving people when surrounded by forest fire, as well as in other situations when it is impossible to prevent ingress of people into a combustion source. Mobile device for protection of people against forest fire has a hollow shell made in the form of a hemisphere, covered from the outside with layers of materials with different properties of protection against thermal effects of fire, and inside hollow shell of housing from top to bottom in a circle is divided with partitions from air-impermeable fabric, which form separate cavities, interconnected by air junctions alternately on top and bottom of structure in form of labyrinth, and is equipped with pressure control and air release valve, wherein housing bottom has skirt with holes for device fixation on ground surface. Door of the facility is made trapezoidal and is hinged by the upper base to the hollow shell of the housing by means of a heat-resistant flexible material, wherein the door structure in cross-section is similar to that of the housing of the device, wherein air in the door is supplied by means of a hose from the hollow shell of the housing. On the bottom of the internal space of the device, along the entire length of the lower edge of the door opening, there is a valve for fixing the door with textile velvet tape facing the textile velvet tape installed in the lower part of the inner surface of the door, which engage with pressing the door to the valve. Inside the body of the device at the bottom there is a cylinder with air, a reducer and hoses for supply of air to respiratory masks, which also serves for swapping of hollow shell of the body and door through the inlet valve.;EFFECT: mobile means of protecting people against forest fire is proposed.;4 cl, 4 dwg
