Water environment sampling device based on unmanned aerial vehicle

Abstract

The invention relates to the field of water sampling devices, in particular to a water environment sampling device based on an unmanned aerial vehicle. The device comprises a mounting ring, a flight protection mechanism is welded to the bottom end of the mounting ring, a recovery mechanism is clamped to the inner side of the mounting ring, and a collection mechanism is fixedly connected to the bottom end of the recovery mechanism. According to the water environment sampling device based on the unmanned aerial vehicle, water environment collection depth adjustment of the collection mechanism in water is completed through a stepping motor, adsorption of an electromagnet, a limiting spring and an iron ring is relieved, and the limiting spring pushes a collection pipe and a sealing ring to slide on the inner side of a protection shell; and external water enters the inner sides of the protection shell and the collection pipe through water permeable holes, redundant water on the inner sides of the the protection shell and the collection pipe is discharged to the outer side of the collection pipe through a one-way valve, and the water environment sampling efficiency of the device is improved through matching of the recovery mechanism and the collection mechanism. With the water environment sampling device based on the unmanned aerial vehicle adopted, the problems that existing equipment is low in sampling efficiency, has no explosion protection and lacks obstacle avoidance measures are solved.

Description

technical field [0001] The invention relates to the field of water sampling devices, in particular to an unmanned aerial vehicle-based water environment sampling device. Background technique [0002] In the water environment supervision work, it is necessary to carry out regular sampling and inspection of water areas. The outdoor environment is complex, and the traditional sampling method is inefficient. The use of drones to conduct flight sampling in monitoring water areas has fast sampling speed and high efficiency, and is not restricted by topography. [0003] When existing equipment performs water sampling operations in natural waters and polluted waters, it is necessary to overcome the interference of debris floating along the water to perform water environment sampling operations. The natural environment is complex and changeable, and common visual obstacles are removed. Some areas in the natural environment There is a special electromagnetic environment, which can eas...
