Automatic sampler of water quality sampling UAV (Unmanned Aerial Vehicle)

Abstract

The invention discloses an automatic sampler of a water quality sampling UAV (Unmanned Aerial Vehicle). The automatic sampler comprises a main body support, a fixed height sensor, a water sample collecting device, a lifting device, a sample dividing device, a sample storage device and a control circuit board, wherein the water sample collecting device comprises a submersible pump, a pressure and liquid level sensor, a flexible water pipe and a flow sensor and is capable of completing fixed-depth sampling; the lifting device comprises a servo motor, a magnetic encoder, a reduction gear, a slip ring, a bearing, a proximity switch, a telescopic rod and a ceramic eye component and is capable of realizing retracing and releasing functions of the water sample collecting device; the sample storage device is formed by three layers of detachable plastic bottles. According to the automatic sampler disclosed by the invention, the weight of the automatic sampler can be effectively reduced, and the performance of the whole water quality sampling UAV is increased; meanwhile, the fixed-depth sampling is realized through the lifting device and the pressure and liquid level sensor which is additionally arranged in a sampling opening, the water quality collecting device can be retracted during a flying process of the water quality sampling UAV, and the safety during the flying process of the water quality sampling UAV is increased.

Description

technical field [0001] The invention relates to the technical field of water quality sampling equipment, in particular to an automatic sampler for a water quality sampling drone. Background technique [0002] With the development of my country's economy, the pollution of water resources is becoming more and more serious, and the prevention and protection of water resources are getting more and more attention. How to efficiently obtain water quality information is the premise of water pollution prevention and control, and water quality sampling is the key to obtaining water quality information. links. Compared with traditional manual sampling and automatic sampling methods, the use of drones for water quality sampling not only has the advantages of high efficiency and high personnel safety, but also can be sampled in complex environments or places that are difficult for people and ships to reach. Since the multi-rotor UAV technology is basically mature, the key to realize the...

Problems solved by technology

[0003] In the Chinese utility model / invention patent application with the application number 201420430386.5, an additional heavy hammer needs to be added at the end of the suction pipe of the water intake part to ensure that the suction pipe can sink below the water surface, which increases the weight of the entire sampling device; The man-machine is equipped with a fixed-height sensor, which can measure the height of the UAV from the water surface, but it does not measure the length of the water suction pipe, so it is impossible to know the depth of the sampling water quality and the function of sampling at a fixed depth; in addition, because it does not design the suction pipe Pipe device, after the sampling is completed, the suction pipe cannot be retracted, which will bring a greater safety hazard to the flight of the UAV, so that it is impossible to perform over-the-horizon sampling
