AI Technical Summary

Technical Problem

Existing water sampling equipment is difficult to achieve simultaneous multi-layer sampling and cannot adapt to changes in water depth, resulting in problems such as large equipment size and non-adjustable sampling depth.

Method used

The system employs a parallel sampling frame and a traction assembly. The automatic opening and closing of the sampling bottle group is triggered by water flow resistance, ensuring that the multi-layer sampling bottle group rises and falls in parallel. The traction assembly is used to control the state switching and depth adjustment of the sampling frame, thereby achieving automatic synchronous sampling.

Benefits of technology

It enables multi-layer water sampling in a single operation, improving sampling efficiency, reducing human error, adapting to different water depth conditions, preventing sample contamination and leakage, and facilitating sample preservation and analysis.

Abstract

The application relates to the technical field of water resource sampling, in particular to a water conservancy and water resource sampling device which comprises a ship body, a sampling assembly and a pulling assembly, a placing groove area is arranged in the middle of the ship body, an oscillatable parallel sampling frame is arranged in the placing groove area, a plurality of sampling bottle groups arranged at equal intervals are arranged in the parallel sampling frame, a resistance triggering structure is adopted for the sampling bottle group, when the ship body moves, water pressure pushes the sampling outer cylinder to move backward, an inlet is automatically opened to complete sampling; when the ship body stops, a spring can reset the sampling outer cylinder, the sampling outer cylinder seals the sampling inner cylinder, and water samples are prevented from being polluted; the pulling assembly controls the depth of the parallel sampling frame, and the water area with different water depths is adapted, the device can automatically and synchronously collect water samples with different depths at a time, the sampling depth can be adjusted, and the device is suitable for water resource sampling in water areas such as rivers and lakes.
