Water quality sampling unmanned aerial vehicle

Abstract

The invention discloses a water quality sampling unmanned aerial vehicle which comprises an unmanned aerial vehicle body. Four support frames are arranged on the outer wall of a side of the top of theunmanned aerial vehicle body, a motor shell is arranged on the outer wall of a side of the top of each support frame, driving motors are arranged on the inner walls of the bottoms of the motor shells, output shafts of the driving motors are provided with rotary rods, propeller blades are arranged on the outer walls of the rotary rods, a mounting frame is arranged in the middle of the outer wall of the bottom of the unmanned aerial vehicle body, a fixing frame is arranged on the outer wall of the bottom of the mounting frame, a hydraulic cylinder is arranged in the middle of the inner wall ofthe top of the fixing frame, and a telescopic rod is arranged on the inner wall of the bottom of the hydraulic cylinder. The water quality sampling unmanned aerial vehicle has the advantages that theintegral height of the water quality sampling unmanned aerial vehicle can be adjusted, and the water quality sampling unmanned aerial vehicle can be prevented from crashing; negative pressures can beformed inside water storage cavities to carry out sampling, the stability of the water quality sampling unmanned aerial vehicle can be guaranteed in sampling procedures, water quality sampling at fourdifferent depths can be conveniently simultaneously carried out by the water quality sampling unmanned aerial vehicle, and the use performance of devices can be improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle used for water quality sampling. Background technique [0002] Water pollution seriously affects the natural environment and animal health. Water quality testing is becoming more and more important. It can provide important information for the prevention and resolution of water pollution. When testing water quality, water quality sampling is required. [0003] At present, using drones to sample water quality is one of the commonly used water quality sampling methods. Compared with traditional manual sampling methods, it can not only reduce people's labor level, but also has the characteristics of high efficiency and low cost. When taking UAV sampling instead of manual work in large water areas, it can ensure personal safety.

[0003] At present, using drones to sample water quality is one of the commonly used water quality sampling methods. Compared with traditional manual sampling methods, it can not only reduce people's labor level, but also has the characteristics of high efficiency and low cost. When taking UAV sampling instead of manual work in large water areas, it can ensure personal safety. However, in the prior art, when UAV is used for water quality sampling, it can only be fixed for one-time sampling, which is single and unmanned. The water quality sampling equipment is mounted on the bottom of the drone during the sampling process. When the sampling is completed and falls, the sampling equipment will affect the normal whereabouts of the drone, which will seriously cause the drone to break
