Description

The invention relates to the field of transport and medical evacuation vehicles and can be used as a means of air transportation of the wounded, injured and otherwise physically injured. A system for evacuating and transporting casualties and cargo is known (see RU 2819380 C1, 20.05.2024), comprising an asynchronous electric motor, a common shaft, a gearbox, a drum, a trench, a plastic sled, a fastening device, and a cable. This system operates as follows. An asynchronous electric motor, connected to a gearbox, spins the common shaft, on which the drum is located. A cable is wound onto the drum in several turns. The cable is pulled along the trench for a distance of up to 1.5 kilometers and then wound in several turns onto another (matching) drum, secured at a support point so that the cable is taut. A plastic sled is attached to the cable via a fastening device. When the motor rotates the common shaft, the cable begins to rotate between the two drums, pulling the sled. The operators of this system, using communication and surveillance equipment, monitor the operation of the system and participate in loading sleds with the necessary ammunition for the strong point, as well as in transporting the wounded from the strong point. The disadvantage of this well-known technical solution is the short service life of the cable due to excessive wear and abrasion. The closest technical solution to the proposed one is the unmanned aerial vehicle (UAV) for evacuating the wounded and delivering cargo, adopted by the author as a prototype (see RU 2829580 C1, October 31, 2024). This technical solution comprises four pairs of electric motors with propellers, arranged vertically one above the other. The electric motors are attached to the frame using rafters at each of the four corners. The electric motors are powered by rechargeable batteries. The batteries can be recharged by solar panels located on the upper surface of the aircraft. The UAV is additionally equipped with control and radio communication units, a GLONASS satellite navigation system, and optical and thermal imaging surveillance equipment. The UAV for evacuating the wounded and delivering cargo is also equipped with an electric winch with a cable and a grappling hook for lifting equipment and the wounded from trenches and terrain. The unmanned aerial vehicle's fixed chassis is a trapezoidal frame with two skids. One skid, in the middle section, houses a reversible electric motor with a shaft in both directions, with toothed wheels cut into slots for moving perforated guides with a roller at the end. On the opposite side, the skid has slots equipped with an electronic locking and release device. The disadvantages of this well-known invention include the short service life and low strength of the runners, the complex installation of the perforated guides, and the complexity of the process of loading the wounded onto the perforated guides. The technical result of this device is to simplify the process of boarding and disembarking injured personnel from a seat bench. The technical result is achieved in that the device for emergency transportation of injured personnel includes a vehicle in the form of an unmanned aerial vehicle containing a battery, a navigation unit, a control unit, a video camera and a unit of engines with propellers, characterized in that a voltage distributor and a signal receiving and transmitting unit are introduced into it, wherein the terminals of the battery are connected to the input of the voltage distributor, the first, second, third, fourth outputs of the voltage distributor are respectively connected to the power input of the control unit, to the power input of the signal receiving and transmitting unit, to the power input of the video camera, to the power input of the navigation unit, the output of the control unit is connected to the unit of engines with propellers, the output of the navigation unit is connected to the first input of the signal receiving and transmitting unit, the output of the video camera is connected to the second input of the signal receiving and transmitting unit, the output of the signal receiving and transmitting unit is connected to the input of the control unit, in the center of the frame of the aircraft a bench with bamboo belts for sitting injured at four different points of the frame is rigidly fixed with legs aircraft, wherein the battery, navigation unit, control unit, video camera, voltage distributor, signal receiving and transmitting unit and engine block with propellers are located on the frame of the aircraft. The essence of the claimed invention, characterized by the combination of the above-mentioned features, is that, using an unmanned aerial vehicle with a bamboo bench with belts rigidly attached to its frame, it is possible to carry out air transportation of injured personnel from hard-to-reach mountainous areas. The presence of the listed existing features in the claimed device allows for th
