Lake water quality sampling unmanned aerial vehicle based on screen effective sampling

Abstract

The invention discloses a lake water quality sampling unmanned aerial vehicle based on screen effective sampling. The problem that sampling suffers failure because the water quality sampling efficiency of a target water area is low, potential safety hazards exist and a sampling water inlet pipe is easy to block in the prior art is solved. The lake water quality sampling unmanned aerial vehicle based on the screen effective sampling comprises an unmanned aerial vehicle main body, landing gears, a wing, a balancing wing, a positive-negative rotating motor, a winding box, a rotating shaft, a cable, a cable inlet and outlet port, a water quality sampling bottle, a cooling fan, a water quality sampling bottle main body, a sample water inlet pipe, an air outlet pipe, a drop-weight lead block, awater inlet pipe solenoid valve, an outlet air solenoid valve and a screen; the screen comprises a cylindrical screen pipe, a first screen piece and a second screen piece; the outer end of the screenpipe is bent outwards to protrude to form a circle of fixing ring; and the fixing ring is connected with the end part of the inlet end of the sample water inlet pipe through two or more equally-spacedbolts. According to the lake water quality sampling unmanned aerial vehicle based on the screen effective sampling, water quality sampling can be carried out on the target water area on the bank or in places far away from uncharted waters; and therefore, the lake water quality sampling unmanned aerial vehicle based on the screen effective sampling is efficient and safe and achieves smooth sampling; and sampling failure caused by blockage of the water inlet pipe can be effectively prevented.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle for sampling lake water quality effectively based on a sieve. Background technique [0002] There are many lakes in China, and there are more than 2,700 lakes with an area of ​​more than 1 square kilometer, with a total area of ​​about 90,000 square kilometers. In addition, there are tens of thousands of artificial lakes (ie reservoirs). In traditional water quality testing and sampling, testing personnel carry instruments and rent boats to take water samples in the middle of the water. In this way, not only the work efficiency is low but also a large amount of manpower, material and financial resources need to be spent, and there are potential safety hazards in some unknown waters. The water quality sampling bottle in the prior art generally has a water inlet. When the water quality sampling bottle sinks into the water, the sample water enters The water quality sampling bottle and the air in the wa...
