Description

TECHNICAL FIELD

[0001] The utility model belongs to environmental monitoring field, concretely relates to a water sample automatic collection device for environmental protection. BACKGROUND

[0002] Collecting water samples is essential for analyzing and assessing the quality of water bodies, which is crucial for environmental protection, public health, industrial applications, and other fields. Here are some main reasons for collecting water samples: 1. Water quality monitoring: detecting pollutants in water, such as heavy metals, pesticides, chemicals, and microorganisms, to ensure that water quality meets drinking water standards or specific use requirements. 2. Environmental assessment: assessing the extent of pollution in water bodies and monitoring environmental changes, such as acid rain, industrial emissions, and agricultural runoff, which affect water bodies. 3. Public health: ensuring that water quality in the water supply system is harmless to public health and preventing waterborne diseases. 4. Compliance checks: complying with environmental protection regulations and regularly testing to ensure that industrial emissions or agricultural activities do not exceed the allowed standards for pollutant emissions. 5. Fisheries and aquaculture: monitoring water quality to ensure the health of fish and other aquatic organisms and the sustainability of the aquaculture industry. 6. Agricultural irrigation: assessing water quality for irrigation to prevent soil and crops from being harmed by salt and toxic substances. 7. Industrial use: ensuring the quality and purity of industrial water to meet specific process requirements. 8. Water treatment optimization: optimizing the operation of water treatment plants by monitoring water quality at the inlet and outlet to improve treatment efficiency. 9. Scientific research: conducting research in the fields of hydrology, ecology, and environmental science to better understand water cycles and aquatic ecosystems. 10. Disaster response: assessing water quality after floods, leaks, or other environmental disasters to guide emergency response and cleanup efforts. 11. Climate change research: monitoring changes in water quality and quantity to study the impact of climate change on water resources. Collecting water samples is a fundamental step in obtaining this information, and laboratory analysis can provide detailed and scientific data on the condition of water bodies.

[0003] However, existing water sample collection methods have some problems. Traditional manual collection methods are inefficient and pose safety risks, and it is difficult to ensure the accuracy and representativeness of the collection. Some existing automatic collection devices have complex structures and large volumes, making it difficult to deploy flexibly in different environments. Moreover, the operation and maintenance costs of these devices are high, and the technical requirements for the operators are also high. Existing devices may be disturbed by factors such as water flow and debris when collecting water samples, affecting the collection effect. In addition, the sampling frequency and sampling volume of some devices are difficult to accurately control, and cannot meet different monitoring needs. The shortcomings of existing technology: the collection accuracy needs to be improved, and the adaptability to different depths and flow rates of water bodies is insufficient. The reliability and stability of some devices are poor, prone to failure, lack of intelligent control and data management functions, and cannot monitor the collection process in real time and effectively analyze the collected data.
