AI Technical Summary

Technical Problem

In existing technologies, sampling water quality in deep river layers can easily disturb sediments, leading to inaccurate data, and the installation and commissioning of equipment is time-consuming and labor-intensive.

Method used

Design a sampling device for deep-water environmental monitoring of rivers, including a floating mechanism, a load-bearing block and a sampling mechanism. It is powered by solar energy and the sampling mechanism is controlled by a control module to move up and down in the water to achieve undisturbed sampling. The device is also automated for sampling and storage through encapsulation components.

Benefits of technology

It enables permanent sampling in rivers, accurately reflects water quality data at different depths, simplifies equipment installation, reduces manual operation, and improves the representativeness and precision of the data.

Abstract

The application discloses a sampling device for river deep water environment monitoring, which comprises a floating mechanism, a weight block and a sampling mechanism. The floating mechanism is arranged on the river surface and is provided with a solar panel at the top for power supply. A photographing module is arranged above the solar panel, and a control module is arranged in the floating mechanism. The weight block is arranged at the bottom of the river and is connected with the floating mechanism through a center pipe. A strip hole extending upward and downward is formed in the left side of the center pipe. The sampling mechanism is fixedly connected with the center pipe and is arranged between the floating mechanism and the weight block. The device and the control method are used for collecting river water samples of different water layers. The water flow is distributed through the drainage hole by using the water pump to drive the sampling box to sink, and the bottom sediments of the river are not washed up, so that the influence of the water sample is avoided. The sinking depth of the sampling mechanism is controlled by the pipe collecting and releasing. The river water of different depths is periodically sampled according to the requirement. The sampling process does not stir the bottom sediments, and the sampled river water can truly reflect the water quality data.
