Problems solved by technology

[0004] Traditionally, layered collection of water samples is often time-consuming and laborious, requiring the sampler to operate in the water (diving or wading), and the sampling behavior is likely to cause interference to the sampled water body
It is difficult for people to accurately grasp the depth of the water body in the water, which further increases the difficulty of artificial water sample collection in layers
At present, some people have designed related devices for stratified water sample collection, which can be simply divided into two categories. One is to pre-set the depth of water sample collection, which is not easy to adjust on site; the other is to adjust the depth of water sample collection on site. , but the operation of adjusting the collection depth is not fast enough, and it is difficult to meet the personalized layered water sample collection (calculate the depth based on the water surface and the depth based on the pond bottom)
In addition, the existing two types of collection devices have the common defects of high cost, inconvenient portability, possible cross-sampling, and unfavorable continuous sampling. It is of great significance to design a low-cost and easy-to-use water sample layered collection device
Therefore, the volume of the collection device for aquaculture water samples in the prior art is too large, and it will also interfere with the aquaculture environment, and the sampling efficiency is low, the sampling accuracy is low, and the layering accuracy is low

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the examples.

[0032] Such as figure 1 Shown is the overall schematic diagram of the collection device, the aquaculture layered water sample rapid collection device, including a sampling rod, a number of syringe samplers fixed on the side of the sampling rod ( figure 1 Only one syringe sampler is shown in the figure), the first positioning plate 1 and the vial bubble (not shown in the figure) that are arranged on the top of the sampling rod, the second positioning plate 8 that is located at the bottom of the sampling rod, the first The positioning plate can be used for stratified sampling with the water surface as a benchmark, and the second positioning plate 8 is a pond bottom baffle, which can be used for stratified sampling with the pond bottom as a benchmark. The surface of the sampling rod is provided with scales and the length of the sampling rod can be adjusted. The first positi...

Abstract

The invention discloses an aquaculture stratified water sample rapid collection device and method. The device comprises a sampling rod, a plurality of syringe samplers fixed to the side face of the sampling rod, a first positioning plate, a level bubble and a second positioning plate, wherein the first positioning plate and the level bubble are arranged at the top of the sampling rod and the second positioning plate is arranged at the bottom of the sampling rod. The length of the sampling rod is adjustable, the first positioning plate and the second positioning plate are perpendicular to the sampling rod, and a pond bottom fixator is arranged at the bottom of the second positioning plate. According to the method, two depth calculation methods with the water surface as the benchmark and thepond bottom as the benchmark can be supported, and the sampling precision, efficiency and layering precision can be guaranteed while the two benchmarks are considered.

Description

technical field [0001] The invention relates to a water sample collection device and a collection method, in particular to a layered water sample rapid collection device and a collection method for aquaculture. Background technique [0002] Aquaculture accounts for an increasing proportion of my country's agriculture, and the area of ​​aquaculture continues to increase, but unreasonable feeding and management will lead to increased levels of pollutants (COD, nitrogen and phosphorus, heavy metals, microplastics, antibiotics, etc.) . On the one hand, this affects aquaculture itself and reduces the yield and quality of aquatic products. On the other hand, pollutants are easily discharged to external water bodies, causing eutrophication of water bodies and heavy metal pollution, which endanger the natural environment. Regularly testing the water quality of the aquaculture pond mouth can effectively grasp the environmental conditions of the pond mouth, which is helpful for aquacu...
