Description

Technical Field

[0001] This utility model relates to the field of marine environmental monitoring technology, specifically a marine environmental stratification sampling device. Background Technology

[0002] In marine environmental research, stratified sampling and analysis of seawater at different depths is an important means of obtaining marine environmental information. Through stratified sampling, we can understand the physical, chemical and biological characteristics of different water layers in the ocean, such as temperature, salinity, dissolved oxygen content, and plankton distribution. This is of great significance for studying marine ecosystems, marine climate change and marine pollution.

[0003] Existing marine environmental stratification sampling devices are diverse in type and style, but they generally cannot simultaneously collect water samples from different layers of the ocean, only allowing for single-layer sampling. In the dynamically changing marine environment, parameters such as seawater temperature, salinity, and dissolved oxygen content fluctuate rapidly over time. Single-layer sequential sampling results in a large time span for obtaining samples from different water layers, causing samples from different layers to not be in the same time dimension, thus losing the significance of cross-sectional comparison. In some polluted sea areas, pollutants are complexly distributed and easily dispersed. Single-layer sampling cannot comprehensively capture the distribution characteristics of pollutants in different water layers, potentially missing key pollution information. When studying marine ecosystems, the activities and distribution of marine organisms in different water layers are interconnected. Single-layer sampling cannot fully present the true state of the ecosystem. These problems result in a lack of completeness and synchronicity in the final sample data, making it difficult to truly reflect the overall picture of the marine environment. Consequently, it affects the accuracy and reliability of the final survey results in research fields such as marine ecology, environmental change, and marine pollution, failing to meet current needs.

The rope 2 is fixedly installed on the top of the storage box 1, and a water outlet pipe is fixedly installed on the side of the storage box 1.

[0024] The opening and closing assembly 3 consists of a fixed plate 301, an electric push rod 302, a moving rod 303, a partition 304, a connecting rod 305, a baffle 306, and a fixed frame 307. The fixed plate 301 is fixedly installed inside the storage box 1. The electric push rod 302 is fixedly installed on the top of the fixed plate 301. The moving rod 303 is fixedly installed on the moving end of the electric push rod 302. The partition 304 is fixedly installed inside the storage box 1. The moving rod 303 is slidably installed within the partitions 304, which are arranged in a linear array. The storage box 1 is divided into multiple sample storage chambers by multiple partitions 304, which facilitates subsequent stratified sampling. The connecting rod 305 is fixedly installed on the surface of the moving rod 303, the baffle 306 is fixedly installed on the side of the connecting rod 305, and the fixing frame 307 is fixedly installed inside the storage box 1. The side of the baffle 306 is fixedly installed with a protrusion, and the inside of the fixing frame 307 is provided with a sliding groove that matches the protrusion. By allowing the protrusion to slide inside the sliding groove, the baffle 306 can be guided.

[0025] The fixing assembly 5 consists of a fixing body 501, a rectangular plate 502, a limiting rod 503, a pull rod 504, a spring 505, and a strip plate 506. The fixing body 501 is fixedly installed on the side of the storage box 1. The rectangular plate 502 is slidably installed inside the fixing body 501. The limiting rod 503 is fixedly installed at one end of the rectangular plate 502. The pull rod 504 is fixedly installed at the other end of the rectangular plate 502. The spring 505 is sleeved on the surface of the pull rod 504. One end of the spring 505 abuts against the fixing body 501, and the other end of the spring 505 abuts against the rectangular plate 502.

[0026] In use, the storage box 1 is placed in the sampling position using rope 2. The electric push rod 302 is activated to move the moving rod 303 downward, which causes the connecting rod 305 to move the baffle 306 downward, allowing the protrusion to slide inside the groove and guide the baffle 306. The external water sample passes through the filter screen 4 to filter out larger impurities before entering the sample storage chamber. Then, the electric push rod 302 is activated to move the baffle 306 upward to block the filter screen 4, completing the synchronous stratified sampling operation. Afterward, the storage box 1 is removed from the water using rope 2, and the valve is opened to drain the water sample inside the storage box 1. Pulling the pull rod 504 moves the rectangular plate 502 and the strip plate 506 and compresses the spring 505, which allows the limiting rod 503 to disengage from the limiting groove. The filter screen 4 can then be disassembled for cleaning or replacement.
