Water body sampling device for environment-friendly monitoring of river water

Abstract

The invention relates to the technical field of water body sampling, and discloses a water body sampling device for environment-friendly monitoring of river water, which comprises a floating cylinder. According to the water body sampling device for river water environmental protection monitoring, when a target water area needs to be sampled, a worker can start an electric telescopic rod to adjust the distance of a pressure plate, so that the pressure plate drives a connecting rod and a counterweight ball to descend, and water enters a water storage cavity from a water inlet hole, so that the sampling purpose is achieved; when water enters a water storage cavity from a water inlet hole, under the action of water impact force, an anti-blocking ball can move under the action of a special-shaped connecting rod and a tension spring, so that the water inlet hole is exposed, when the water storage cavity is full of water, the internal water pressure and the external water pressure can be consistent, the anti-blocking ball can reset, and then the water inlet hole is blocked; by means of the arrangement, when the balance weight ball ascends, water can be prevented from flowing backwards into the water storage cavity, and sampling water is prevented from being affected.

Description

Technical field [0001] The present invention relates to the field of water sampling technology, specifically a river water environmental protection monitoring water body sampling device. Background [0002] Human beings in life and production activities are inseparable from water, the quality of drinking water is closely related to human health, with the social and economic development, scientific progress and the improvement of people's living standards, people's water quality requirements for drinking water continue to improve, drinking water quality standards are also correspondingly continuously developed and improved, in order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge, because the water body monitoring needs to be sampled and analyzed, the existing methods are mostly directly sampled through artificial handheld containers, which are inefficient and have the risk of drowning, It is also not possible to accurately sample...

AI Technical Summary

Problems solved by technology

[0002] Human beings are inseparable from water in life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing. , the drinking water quality standards are also continuously developed and improved accordingly. In order to protect the water environment, the monitoring of sewage discharge must be strengthened. Since water body monitoring requires sampling and analysis, the existing methods mostly use manual hand-held containers to directly sample, which is inefficient and Risk of drowning and inability to accurately sample the target water layer

[0003] When it is necessary to take deep water, during the rising process of the sampling device, the upper water will flow backward into the sampling device, and then pollute the sampled water, making the monitoring results inaccurate and unable to accurately monitor the quality of deep water
