Problems solved by technology

[0005] The existing UAV landing gears are all fixed, and the structure and function are too simple to adjust the form according to the flight and landing of the UAV. At the same time, the shock absorbing device of the existing UAV landing gear is relatively simple, so Affect the stability of the drone when it lands, and it is easy to cause damage to the drone

Abstract

The invention discloses an unmanned aerial vehicle undercarriage for forestry fire prevention. The unmanned aerial vehicle undercarriage comprises a base and a lifting base, a first screw rod is rotationally mounted in the middle of the base and is in threaded connection with a first screw sleeve, and a plurality of sliding grooves are evenly formed on the base and at the periphery of the first screw. The sliding blocks are mounted in the sliding grooves in a sliding manner, the lifting seat is arranged above the base, and a plurality of push-pull rods are hinged to the periphery of the lifting base and are in a one-to-one correspondence with the sliding blocks. The lower ends of the push-pull rods are hinged to the sliding blocks at the same side, a plurality of first connecting rods arehinged to the outer sides of the first threaded sleeve, the first connecting rods are in one-to-one correspondence with the push-pull rods, and the other ends of the first connecting rods are hinged to the inner sides of the push-pull rods. When an unmanned aerial vehicle lands, the lifting base moves upwards, the resistance between the undercarriage and the air is increased, so that the stable landing of the unmanned aerial vehicle is guaranteed. When the unmanned aerial vehicle takes off, the resistance between the undercarriage and air is reduced, so that the unmanned aerial vehicle takes off quickly.

Description

technical field [0001] The invention relates to the technical field of forestry fire prevention, in particular to an unmanned aerial vehicle landing gear for forestry fire prevention. Background technique [0002] Forest is a biological community with woody plants as the main body. It is an overall ecosystem formed by the interdependence and mutual restriction between concentrated trees, other plants, animals, microorganisms and soil, and the interaction with the environment. [0003] Forest fire is the most dangerous enemy of the forest and the most terrible disaster of forestry. It will bring the most harmful and destructive consequences to the forest. Forest fires not only burn the forests, harm the animals in the forests, but also reduce the reproductive capacity of the forests, cause soil barrenness and damage the water conservation of the forests, and even lead to the imbalance of the ecological environment. [0004] Unmanned aircraft is referred to as "UAV" for short...
