Problems solved by technology

When microplastics floating on the water surface or sinking into the sediment are eaten by plankton or benthic animals, they will have a serious impact on aquatic organisms in different water environments, including oceans, rivers and lakes, and will be transported through the food chain and enrichment, which may eventually endanger human health. In addition, microplastics are also an important carrier of alien species invasion and infectious pathogenic microorganisms in the water environment, and have potential risks to changes in the regional and global ecological environment.

Embodiment 1

[0030] See attached Figure 1-8 As shown, the real-time monitoring and early warning device for microplastics in aquaculture water includes:

[0031] The buoyancy assembly 10, the buoyancy assembly 10 is all arranged in the aquaculture waters, the buoyancy assembly 10 is equipped with a suction pipe body 23 and an air pipe 24, and the liquid suction pipe body 23 and the air pipe 24 are respectively connected to the pump body assembly 21,

[0032] Collection box body 20, collection box body 20 is arranged on the land base near aquaculture waters, arranges and places sampling pipe in collection box body 20, and sampling pipe body is connected with the pumping pipe body 23 on each buoyancy assembly 10 respectively,

[0033] Wherein, the buoyancy assembly 10 includes a second buoyancy plate body 15, the two ends of the second buoyancy plate body 15 are connected to the first buoyancy plate body 12 which is vertically arranged therewith, the second buoyancy force plate body 15 and ...

Embodiment 2

[0045] The further optimization scheme of present embodiment on the basis of embodiment 1 is: see appendix Figure 8 As shown, the upper and lower ends of the buoyancy cylinder 61 are respectively provided with a first bearing ring 63, the inner diameter of the first bearing ring 63 is larger than the diameter of the elevating rod body 50, and the outside of the buoyancy cylinder 61 is provided with a rectification screw 66 parallel to its axis, and the upper and lower ends of the rectification screw 66 A second bearing ring 65 is provided respectively, and the second bearing ring 65 is connected to the first bearing ring 63 through a buffer connecting rod 64 . The rectification screw 66 on the side of the buoyancy cylinder 61 is used to rectify the water body below the connection base 41 when the buoyancy cylinder 61 goes up and down with the connection base 41. The flow of leaves is conducive to the formation of centrifugal force, especially for the possible aggregation of s...

Abstract

The invention discloses a real-time monitoring and early warning device for aquaculture water microplastics, which belongs to the technical field of water environment monitoring equipment; the device comprises a buoyancy assembly and a collecting box body; a liquid pumping pipe body and an air pipe are arranged on the buoyancy assembly, sampling pipes are arranged in the collecting box body, and the buoyancy assembly comprises a second buoyancy plate body; the two ends of the second buoyancy plate body are connected with a first buoyancy plate body perpendicular to the second buoyancy plate body, the second buoyancy plate body and the first buoyancy plate body form an I-shaped structure, a through hole is formed in the middle of the second buoyancy plate body, and a lifting rod body capable of lifting up and down is inserted into the through hole. According to the invention, the distribution of micro-plastic particles in an aquaculture water area range is effectively monitored; The concentrations of the micro-plastic particles in the water layers with different depths are monitored in real time, so that sampling accuracy and data accuracy are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water environment monitoring equipment, and in particular relates to a real-time monitoring and early warning device for microplastics in aquaculture water. Background technique [0002] Due to the characteristics of plastics such as wear resistance, corrosion resistance, stability, light weight, firmness, and low cost, plastics are widely used in various fields of modern life. Due to the renewal and waste of plastics, a large amount of plastic waste is discharged into the environment, and plastic waste is difficult to degrade, easy to absorb pollutants and microorganisms, and the ecological environment problems caused by it have become the focus of attention of countries all over the world. In 2004, Thompson et al. (2004) first proposed the concept of "microplastics". The generally accepted definition is a collective term for plastic particles with a particle size of less than 5mm, which are formed by th...
