Unmanned aerial vehicle used for collecting water samples and having high safe performance

Abstract

The invention relates to an unmanned aerial vehicle used for collecting water samples and having high safe performance. The UAV includes a body and an undercarriage, and includes a collection mechanism and at least two self-rescue mechanisms. The collection mechanism includes a first support frame, a lifting assembly, a first driving assembly, a moving assembly, and at least two sampling assemblies. Each sampling assembly includes a baffle, a sleeve, a connection rod, a first piston, a water inlet, and two springs. Each self-rescue mechanism includes a second driving assembly, a guide pipe, asecond support frame, an air cylinder, a second driving bar, a second piston and an airbag. During use of the UAV, the UAV can collect water samples from different positions in one flight period by using the collection mechanism, so that round trip times of the UAV are reduced and water sample collection efficiency of the UAV is increased. By means of the self-rescue mechanisms, when the UAV is forcedly landed on water surface due to exhaustion of power, the UAV can be floated above the water surface and is free of damage due to water invasion, thus reducing unnecessary loss.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with high safety performance for collecting water samples. Background technique [0002] Unmanned aircraft, referred to as UAV, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Compared with manned aircraft, UAVs are often more suitable for those dirty or dangerous tasks. Man-machines can be divided into military and civilian uses according to the application field, which greatly expands the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology. [0003] Generally, when UAVs collect water samples, since the UAVs can only collect water samples from one place at a time, the UAVs need to return to the voyage multiple times, which reduces the efficiency of UAVs in collecting water samples. Not only that, but generally The...

Problems solved by technology

[0003] Generally, when UAVs collect water samples, since the UAVs can only collect water samples from one place at a time, the UAVs need to return to the voyage multiple times, which reduces the efficiency of UAVs in collecting water samples. Not only that, but generally The duration of drones is limited. If the drone is forced to land in the water due to exhaustion of power during the flight, it will bring huge losses to people.
