Karst region field unmanned aerial vehicle-based remote water sample collection device

Abstract

The invention discloses a karst region field unmanned aerial vehicle-based remote water sampling device, and the device comprises an unmanned aerial vehicle and a sampling cylinder connected with theunmanned aerial vehicle through a rope; the sampling cylinder comprises a cylinder body with a closed bottom end and an incompletely closed top end, the closed bottom end of the cylinder body is a bottom plate, and the top end of the cylinder body is a closed bottom plate; a closed part at the top end of the barrel is a cover plate fixedly connected to the barrel, an unclosed part is an opening, and a stop block is arranged on the inner wall of the unclosed part at the top end of the barrel in the circumferential direction; a water inlet, a one-way valve and a sealing device for realizing liquid sealing between the one-way valve and the water inlet are arranged on the bottom plate, an overflow hole is formed in the cover plate, and a semi-open one-way valve and a closing device for closingthe semi-open one-way valve are arranged on the lower surface of the cover plate. The device provided by the invention can realize automatic sealing of the sampling cylinder, effectively reduces or even avoids splashing loss of a water sample in flight, and can well avoid splashing loss of the water sample in the sampling cylinder even if encountering an obstacle.

Description

technical field [0001] The invention relates to a water sample collection device, in particular to a remote water sample collection device based on an unmanned aerial vehicle in a karst area. Background technique [0002] Karst areas are affected by complex geological conditions, and traffic varies greatly. Field geological surveys in karst areas are greatly affected by complex traffic. Often, sampling points that are close to your eyes need to climb mountains or cross rivers and bridges to reach the straight-line distance. Obtaining water samples at a sampling point of several hundred meters not only increases the labor intensity of the sampling personnel, but also greatly reduces the work efficiency. Some sampling sites still need to cut down trees to open the way, which increases the safety risk of field operations. [0003] In order to overcome the above difficulties and improve the efficiency of water sample sampling in places with inconvenient transportation in karst ...

AI Technical Summary

Problems solved by technology

However, in the technical solution described in the application, the water sample collection device needs to be completely submerged in the water to sample. Even if the water intake cup is made of transparent plastic, it is difficult to tell whether the water sample is full of the cup body; and the water inlet hole of the water sample collection device cannot Automatically closed, if you encounter obstacles during the return journey after sampling, you may not be able to obtain water samples or obtain a sufficient amount of water samples
