Portable surface-layer seawater sampling device

Abstract

The invention relates to the technical field of seawater detection and discloses a portable surface-layer seawater sampling device. The portable surface-layer seawater sampling device comprises sampling equipment, wherein a supporting plate is fixedly arranged at the top part of the sampling equipment; a gripping rod positioned under the supporting plate is movably connected at the side surface ofthe supporting plate; a supporting block is fixedly arranged at the bottom part of the gripping rod; a supporting rod is movably connected at the inner surface of the supporting block; one end of thesupporting rod penetrates through and extends to the inner part of the sampling equipment. The portable surface-layer seawater sampling device disclosed by the invention has the beneficial effects that by the action of the sampling equipment, the surface-layer seawater can be directly absorbed, so that the detection for the seawater quality is convenient, the seawater is prevented from being polluted to influence the ecological health, meanwhile the sampling equipment is convenient in use and carry; by utilization of the gripping rod, the sampling equipment extends into water, and the surface-layer seawater can be pumped by directly pulling the gripping rod, so that the convenience of the sampling equipment in carrying is improved; by utilization of the action of the supporting block, thephenomenon that the supporting rod is blocked when in movement is prevented.

Description

technical field [0001] The invention relates to the technical field of seawater detection, in particular to a portable surface seawater sampling device. Background technique [0002] Collect water samples from polluted water bodies and analyze and measure them to obtain basic data on water body pollution. The water samples used for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, location, time, frequency, etc. All are determined according to the characteristics of the water body and the purpose of analysis. [0003] The invention with the existing application number CN201410618813.7 discloses a seawater quality sampling device, which can provide online monitoring of seawater from time to time, and at the same time can perform double seawater quality monitoring of on-line monitoring and laboratory water quality testing for seawater in special waters ; [0004] Although this invention solves s...

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a portable surface seawater sampling device, which has the advantages of filtration, leakage prevention, and portability, and solves the problem that most seawater sampling devices directly adsorb seawater on the surface during the sampling process. , without filtering the suspended solids on the surface of the seawater, the residue will easily block the sampling device after long-term use. At the same time, after the sampling is completed, the seawater will easily flow out of the sampling device. The sampling device is too large and it is not convenient to carry.
