Description

Technical Field

[0001] This application relates to the field of seawater sample dispensing technology, and in particular to a dispensing device for parallel seawater samples from a water sampler. Background Technology

[0002] Seawater is water from the ocean. Seawater is fluid, and for humans, the amount of usable water is unlimited. Seawater is a veritable liquid mineral resource, with an average of 35.7 million tons of minerals per cubic kilometer. Of the more than 100 known elements in the world, 80% can be found in seawater. Seawater is also a source of freshwater for land and a regulator of climate. Every year, 4.5 million cubic kilometers of freshwater evaporate from the world's oceans, of which 90% returns to the ocean through rainfall, and 10% falls to the land as rain and snow, then returns to the ocean via rivers. Seawater desalination technology is developing into an industry.

[0003] A water sampler is a device used to collect seawater samples. Currently, commonly used water quality sampling equipment is rope-pulled and has only one outlet. GB17378.3 Marine Monitoring Standard proposes that on-site parallel samples refer to two parallel samples collected under the same sampling conditions and sent to the laboratory for analysis.

[0004] When laboratory precision is under control, it mainly reflects the changes in precision during the sampling process. For parallel samples in the field, it is important to control the consistency of sampling operations and conditions. Therefore, it is necessary to ensure that parallel samples are taken at the same time to ensure the homogeneity and repeatability of the samples as much as possible.

[0005] Therefore, this application proposes a device for dispensing parallel samples of seawater from a water sampler. Utility Model Content

[0006] This application proposes a parallel sample dispensing device for seawater samples from a water sampler to solve the problems mentioned in the background art. By setting up an outlet pipe, connecting hose, T-junction pipe, and water distribution hose, it can simultaneously collect parallel samples, ensuring the homogeneity and repeatability of the samples as much as possible. Through the T-junction, the samples are simultaneously dispensed from one water sampler into two sampling bottles, ensuring the parallelism of the sample collection. By setting up a first sealing ring, a second sealing ring, and a third sealing ring, the sealing of the connection between the pipes is ensured, preventing leakage. This ensures the parallelism of the seawater sample collection and greatly improves the practicality of the device.
