Water sampling device for farming water quality monitoring

Abstract

The invention relates to a water sampling device for farming water quality monitoring. The water sampling device comprises a peristaltic pump (8) and a water quality sensor (9), wherein the front end of the peristaltic pump is connected with a hose (2), the rear end of the peristaltic pump is connected with the water quality sensor (9), the front end of the hose can extends to the inside of a to-be-monitored water area, the peristaltic pump (8) is provided with a driver, a corresponding control module is arranged in an external computer, and the flow rate and velocity of the peristaltic pump (8) are controlled by using an external computer (12) through the control module, so that the peristaltic pump (8) meets the requirements of the water quality sensor (9) on flow velocity and flow rate. By using the water sampling device for farming water quality monitoring disclosed by the invention, the sampling flow rate and the sampling flow velocity can be automatically controlled, and the original water in the water quality sensor and a pump body can be accurately and rapidly discharged so as to meet the requirements of the water quality sensor on flow rate and flow velocity, thereby greatly improving the accuracy and rapidness of monitoring.

Description

technical field [0001] The invention relates to a water sample sampling device for aquaculture water quality monitoring, which belongs to the technical field of aquaculture equipment. Background technique [0002] The aquaculture water body is not only the living place of the aquaculture object, but also the decomposition container of feces and residual bait, and the cultivation pond of plankton. The ecological imbalance among them causes a large amount of organic matter and toxic and harmful substances to accumulate in the water, which not only seriously affects the survival and growth of farmed animals, but also becomes one of the main pollution sources of the natural water environment. Therefore, how to maintain the ecological balance of the water environment is a key technology for high-quality and efficient aquaculture. To do a good job in water quality control, we must first understand the water quality parameters of the aquaculture water body. Professional water qua...

Problems solved by technology

[0003] The technical problem solved by the present invention is: professional water quality monitoring instruments have accurate test data, but are expensive and inconvenient to move, require professionals to use, and cannot serve a large number of aquaculture waters; water quality parameters of aquaculture water bodies are closely related to environmental factors , the existing water quality monitoring instruments do not monitor temperature, humidity, light and other environmental factors, especially the light, which affects the accuracy of evaluating the water quality of the aquaculture water; the existing water quality monitoring instruments cannot automatically locate the monitoring points, thus requiring It is inconvenient and inaccurate to manually record the position of the monitoring point during each monitoring; the existing water quality monitoring device needs to be manually installed in the water area to be monitored, and it is very inconvenient to set and adjust the position of the sampling device, which greatly reduces the repeated use performance and p
