Unmanned aerial vehicle flight platform for intelligent geographic remote sensing surveying and mapping

Abstract

The invention relates to an unmanned aerial vehicle flight platform for intelligent geographic remote sensing surveying and mapping. The platform comprises an unmanned aerial vehicle body, a landing frame, a buffer mechanism, a bracket, a switching mechanism and a transmission mechanism. The landing frame is arranged below the unmanned aerial vehicle body. The buffering mechanism comprises a supporting column, an electromagnet, a permanent magnet and a spring. The switching mechanism comprises a power supply, an outer shell, an inner cylinder, a plurality of conductive columns, an output shaftand a plurality of blades, and the transmission mechanism is configured to transmit downward movement of the supporting column under the pushing of the unmanned aerial vehicle body to the output shaft and enable the output shaft to rotate for electric conduction. When the unmanned aerial vehicle flight platform for intelligent geographic remote sensing surveying and mapping lands, the reverse thrust repulsion intensity can be adaptively adjusted according to the descending speed of the unmanned aerial vehicle body when the unmanned aerial vehicle body lands, and the buffering effect of the unmanned aerial vehicle body during landing is improved. Preferably, the unmanned aerial vehicle body stops descending before the spring balance point, and at the moment, even if the repulsive force ofthe electromagnet is removed, the unmanned aerial vehicle body cannot rebound.
