RU216091U1 - UNMANNED AERIAL VEHICLE FOR RESCUE OF PEOPLE IN FIRE FROM HIGH-STOREY BUILDINGS - Google Patents

Abstract

The utility model relates to the field of rescue equipment in the air, in particular, unmanned aerial vehicles for rescuing people in case of fire from high-rise buildings. The objective of the utility model is to quickly and safely rescue people from high-rise buildings using a controlled UAV. The task is achieved by using a drone (quadcopter) of increased payload capacity with a hinged long ladder, at the end of which there is a cradle for transporting people hinged to it. The UAV is equipped with a container with a fire extinguishing agent, which is fed through a hose to the hydraulic control at the end of the ladder using a pump to create a finely sprayed jet (water curtain) (Fig. 1). The advantage of this device lies in the faster activation of this device, high maneuverability and rapid climb, the presence of an additional device that can protect a person from fire hazards by creating a water curtain.

Description

This utility model relates to the field of air rescue equipment, in particular unmanned aerial vehicles (UAVs) for rescuing people in case of fire from high-rise buildings.

Known rescue aircraft using the lifting force of the carrier gas. The aircraft has a rigid body, inside of which there are shells with a carrier gas, propellers inside the aerodynamic modules in the form of bodies of revolution of a toroidal shape with an aerodynamic profile. A through longitudinal passage is made in the lower part of the hull, connecting the cockpit, cargo-passenger cabin, fuel tanks and units, equipped with exit hatches and devices for mooring to external objects, a retractable gangway with railings and a removable trolley. There is a transverse passage with access to the wings and a vertical passage equipped with a winch and devices for lowering and lifting. The lower part of the hull and hollow wings are filled with foam, which provides buoyancy and strength to the aircraft, and act as side stabilizing floats. The invention is aimed at expanding the arsenal of technical means [rescue aircraft, patent RU 2337855 C1, authors Khakimov B.V., Chernikov A.N., Demidov G.V., Khamitov R.Z., published 10.11.2008, Bull. No. 31].

The disadvantages of this device can be considered: the use of gas to create a lifting force, which can create a fire and explosion hazardous situation when saving people from a fire; low maneuverability, as well as the high cost of this design.

The closest in technical solution and selected for the prototype is a rescue aeronautical apparatus [Rescue aeronautical apparatus, patent RU 2 752 038 C2, author Perfilov A.A., published 22.07.2021 Bull. No. 21]. The rescue aeronautical vehicle includes a multicopter, a gondola, an automated control system, a battery pack, cargo container grips, an orientation and tracking system. The body in the form of an ellipsoid is formed by polymer hoops - stiffeners located in the meridian direction. On top of the hull is a multicopter with electric propulsion, automated control systems and space navigation, terrain orientation and dispatch communication devices. From the bottom of the body there are grips of the cargo container holding the tensioner and the battery pack. Inside the body of the device there is a gondola, consisting of several gas tanks, and a bed made of porous rubber for receiving people in distress. The invention is aimed at improving reliability and maneuverability, while the weight of the apparatus and the payload - people is fully compensated by the lifting force of gas tanks, while lightweight and economical electric propulsion devices are used mainly for maneuvering and stabilizing the flight.

The disadvantages of the prototype are:

1) The use of gas (helium), which, when in contact with fire, can create a fire and explosion hazard situation that can harm the life and health of evacuated people.

2) The device is not intended for flying with people over a distance, which makes it impossible to transport people to a safe distance from an open source of fire, followed by a safe landing.

3) To hold the device at the proper height, a tension device is used, which increases the time of its stabilization and hovering in the air.

The problem solved by the utility model is to quickly and safely rescue people from high-rise buildings using a controlled UAV.

The task is achieved by using a drone (quadcopter) with increased payload capacity with a hinged long frame, at the end of which there is a cradle for transporting people hinged to it. The UAV is equipped with a container with a fire extinguishing agent, which is fed through a hose to a spray nozzle at the end of the ladder using a pump to create a fine spray jet (water curtain) (Fig. 1).

The device consists of a UAV 1, on supports 8, a frame 2 hinged to the UAV, to which, in turn, a cradle made of non-combustible materials 3 is hinged, the front side of which is made in the form of a seat mounted on the frame of the spray nozzle 5, a fire hose 4 connected with a water tank 6 using a pump 9, a winch 7 attached to the UAV, connected to the frame 2.

The principle of operation is as follows. The UAV in the transport position I (Fig. 2) controlled by the dispatcher, quickly gains the required height, flies up to the place of rescue of a person, in the presence of dangerous fire factors that may threaten the evacuee, is supplied using a pump 9 through a hose 4 through a spray nozzle 5 finely sprayed water jet, creating the so-called "water curtain", the rescued climbs into the cradle 3, made of non-combustible materials and takes a sitting position, after the person takes the transport position, the frame 2 with the winch 7 takes the transport position II (Fig. 3), the UAV is shifted to a safe distance from the building and goes down and the rescued person leaves the cradle.

The advantage of this device over the prototype lies in the faster bringing this device into working condition, in high maneuverability and quick climb, in the presence of an additional device that can protect a person from fire hazards by creating a water curtain.

Claims (1)
