Description

Technical Field

[0001] This utility model relates to the field of water quality sampling equipment technology, and in particular to a high-safety automatic water quality sampling system. Background Technology

[0002] An automatic water sampler is an intelligent sampling device that can automatically collect and store water samples at appropriate times based on preset time, frequency, and triggering conditions. Besides collecting samples, it can also monitor water quality parameters. Compared to traditional manual sampling, automatic water samplers not only have higher sampling efficiency but also provide real-time monitoring of water quality parameters, ensuring data accuracy and reliability. Automatic water samplers are widely used in water quality monitoring, environmental protection, and scientific research. In water quality monitoring, automatic samplers can conveniently and continuously collect water samples and monitor various water quality parameters, thereby promptly identifying water quality problems and ensuring water health. In environmental protection, automatic samplers can monitor and sample pollution sources 24 hours a day, better understanding the real-time situation of pollution sources and ensuring environmental safety. In scientific research, automatic samplers can collect and preserve large amounts of water quality data, providing data support for scientists. Today, automatic water samplers have become indispensable equipment in water quality monitoring, environmental protection, and scientific research, and their functions and applications are widely recognized and used. However, it is also necessary to recognize that automatic water samplers still need further improvement and development to meet the needs of different fields.

[0003] Currently, automated water samplers still have some areas for improvement in practical applications. Regarding the design of the sampling bottles, most samplers on the market are open-topped and lack self-sealing capabilities, making it easy for water samples to spill after sampling, and compromising the original quality of the samples. Furthermore, with traditional automated water samplers, it is difficult for staff to monitor the water samples throughout the collection and transportation process, resulting in a lack of strict quality control and potentially affecting laboratory test results. Market research on automated water samplers shows that no current product can guarantee real-time monitoring of the collected water samples throughout the entire collection and transportation process. Therefore, a highly secure automated water sampling system needs to be designed that can ensure sample quality during transportation after water sampling is completed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology and provide a highly secure automatic water sampling system that can be monitored and controlled remotely in real time, ensuring the safety and quality of water samples throughout the entire process of sampling and transportation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
