Apparatus for collecting water and sampling on multiple points as well as unmanned aerial vehicle sampling system and sampling method

Abstract

The invention discloses an apparatus for collecting water and sampling on multiple points as well as an unmanned aerial vehicle sampling system and sampling method, which belongs to the technical field of acquisition of a water sample. The apparatus is provided with parts such as a shell, an upper plate, a bottom plate, a coiled pipe assembly, a position adjusting assembly and a water collection assembly, wherein corresponding parts in the coiled pipe assembly are accurately controlled by virtue of the position adjusting assembly, the flushing process and water injection process of a water pipe can be realized, and the water quality detection process of a sampled water area can be completed by virtue of the water collection assembly, so that the collection of various water samples in various water areas can be accurately and rapidly realized. The multi-point water collection and sampling apparatus has the advantages that the structure is simple and the setting is simpleand convenient;the control method of the unmanned aerial vehicle sampling system carrying the multi-point water collection and sampling apparatus is simple; and the rapid collection of a plurality of water samples in various water areas can be effectively realized, the accuracy of the water sample in the collection process can be ensured, the pollution of the sample and the damage to the part can be reduced, thewater sample collection efficiency is improved, the water quality detection accuracy is improved, the water quality detection cost can be reduced, and the application prospect and application popularization value are relatively good.

Description

technical field [0001] The invention belongs to the technical field of water sample collection, and in particular relates to a multi-point water sampling device, an unmanned aerial vehicle sampling system and a sampling method. Background technique [0002] Water resources play an essential role in daily life and industrial production. With the continuous development of society and the continuous progress of industrial technology, the pollution of water resources is becoming more and more serious, which has become a worldwide environmental governance problem and seriously threatens the sustainable development of society. In view of this, the country is vigorously strengthening the work related to water resource protection and water environment governance, aiming to slow down or control the increasingly serious water pollution problems. [0003] In the process of water pollution control, water quality testing and analysis are indispensable. Only by clarifying the essential c...

Problems solved by technology

[0006] 1. Although the above-mentioned water sample collection device can realize the collection of multiple samples, it cannot realize the cleaning of water passing devices such as water pumps and water pipes during the collection process. In this way, its multi-sample collection is only suitable for single-point multi-sample collection. If It collects multiple points and multiple samples, and the water samples collected later are easily polluted by the water samples collected last time, resulting in errors in water quality testing;

[0007] 2. The retraction and release process of the above-mentioned water sample collection device, the alignment control process between the water injection joint and the sampling bottle mouth cannot be accurately realized, so that it is impossible to accurately know whether the water intake pipe is retracted in place during the sampling process, and it is also impossible to ensure accurate injection of water samples In the correct sampling bottle, it will affect the accurate development of the water intake process, and will also adversely affect the service life of the pipeline retracting mechanism;

[0008] 3. Although the above-mentioned water sample collection device can use the water pressure sensor and water temperature sensor on the submersible pump to detect the water pressure and water temperature in the water sample area, the core parameters of the water sample area, such as pH value, dissolved oxygen, and conductivity , turbidity, etc., which cannot be accurately detected and fed back, and these key parameters often change with time changes after water sample collection, temperature changes, and external influences during transportation, resulting in distortion of water quality test results and affecting the quality of water. Correct judgment of water quality;

[0009] 4. The structure of the above-mentioned water sample collection device is complex, difficult to repair and maintain, and the motor and steering gear are set up for two-stage drive. The driving process of the components is cumbersome, which can easily cause large coupling errors and affect the normal operation of the water sample collection device. work and accurate sampling, there are certain application limitations
