Suspension type UAV (unmanned aerial vehicle) water sampler system

Abstract

A suspension type UAV (unmanned aerial vehicle) water sampler system comprises a UAV, a sampling control system and a sampling cup, wherein the sampling control system comprises a motor fixing plate, a wire reel, a center control board, a self-locking motor, a coupling, a rotary encoder, a sampling motor, a return baffle, a return buffer, a water level determining probe, a self-locking gear, a sampling cup pull rope and a return switch. The UAV stably stays at a specific height above the water surface through height determination, then the sampling cup accurately reaches a designated position underwater by controlling the number of turns of the wire reel, and finally, the sampling cup full of water samples firmly stays in the center of the bottom of the UAV through return sensing and the self-locking mechanism. The system can automatically finish the whole water sample collecting process and return through programs and requires no manual intervention. The major advantage of the system is the reliable, stable, intelligent, convenient and up-to-standard sampling process.

Description

technical field [0001] The invention relates to the technical field of water quality sampling equipment, in particular to a suspended unmanned aerial vehicle water quality sampler system. Background technique [0002] As the Chinese government pays more and more attention to environmental issues, it is imminent to systematically promote the work of water pollution prevention, water ecological protection and water resource management. Efficient and comprehensive acquisition of water quality information is a prerequisite for water pollution prevention and control, and water quality sampling is to obtain water quality. key link of information. In order to improve the work efficiency of this key link and quickly complete the water sample collection task in emergency situations and complex environments, it is very necessary to invent a fast, efficient, and fully intelligent water sample collection tool. At present, most of the sampling work is done by people. The disadvantages o...

Problems solved by technology

At present, most of the sampling work is done by people. The disadvantages of manual sampling are: 1. High cost, low efficiency, time-consuming and labor-intensive

2 Unable to adapt to complex and unfamiliar environments

UAVs are also used to complete sampling. For example, the patent [CN203975222U] proposes a sampling UAV that uses water pumps and suction pipes to extract water samples at high altitudes. The advantage of this method is that the design of the sampling mechanism is relatively simple and the load is relatively light. But the disadvantages are: 1. adopt the pump extraction method, when there are many pollutants in the water body, the sampling pipeline is easy to block, if blockage occurs, it cannot be detected in time

2 The sampling pipeline is easy to breed various microorganisms for a long time, and it needs to be cleaned or replaced regularly

3 Some measurement indicators such as dissolved oxygen will change significantly during the extraction process, resulting in measurement errors
