A system for collecting water ecological environment parameters

Abstract

The invention relates to a collecting system for aquatic ecological environment parameters. The collecting system comprises a plurality of sensors, a monitoring measurement center, a fixing frame, a de-foaming sediment device, a connecting pipeline, a cleaning device and a plurality of control valves, wherein the de-foaming sediment device, the connecting pipeline and the cleaning device are arranged on the fixing frame; a liquid inlet and a liquid outlet are formed in the connecting pipeline; the de-foaming sediment device comprises a barrel and a liquid feeding pump; a water feeding pipe and a water draining pipe are arranged on the barrel; an output pipe of the water feeding pipe is communicated with the liquid inlet; the water draining pipe is communicated with the liquid outlet; the sensors are arranged on the connecting pipeline; the cleaning device is connected with the water feeding pipe; the control valves are arranged on the connecting pipeline; and the monitoring measurement device is connected with the liquid feeding pump, the sensors and the cleaning device. The system provided by the invention adopts distributed and multi-point data collection, is convenient to move and is capable of realizing the switching of a detection flow path, a cleaning flow path and a backwashing flow path. The cleaning and backwashing can be utilized to effectively prevent biological attachment so as to guarantee accuracy of long-term measurement.

Description

technical field [0001] The invention belongs to the field of water ecological environment monitoring, in particular to a water ecological environment parameter data collection system. Background technique [0002] Water quality and ecological parameters are an important part of seawater and freshwater environmental monitoring and scientific research. At present, there are a variety of commercial instruments and designs, mainly including three categories. The first category is a portable multi-parameter water quality parameter instrument, which can meet short-term on-site The disadvantage of rapid measurement is the lack of effective automatic cleaning device and anti-biological adhesion design, and it is difficult to upload data to the server in real time, so it cannot work automatically and continuously for a long time; the second type is the submerged water quality ecological environment monitoring system based on buoys or submersible buoys , through the built-in battery o...

[0002] Water quality and ecological parameters are an important part of seawater and freshwater environmental monitoring and scientific research. At present, there are a variety of commercial instruments and designs, mainly including three categories. The first category is a portable multi-parameter water quality parameter instrument, which can meet short-term on-site The disadvantage of rapid measurement is the lack of effective automatic cleaning device and anti-biological adhesion design, and it is difficult to upload data to the server in real time, so it cannot work automatically and continuously for a long time; the second type is the submerged water quality ecological environment monitoring system based on buoys or submersible buoys , through the built-in battery or solar battery to realize the long-term work in situ in the water environment, the disadvantage is that the maintenance of the system and sensors is difficult, the maintenance cost is high, and there is no unified automatic cleaning or anti-biological adhesion design, only some sensors have anti-biological adhesion or mechanical cleaning At the same time, due to the limitation of power supply, the types of sensors that can be supported and the sampling frequency are very limited, and it is difficult to support high-frequency, high-energy-consuming ecological environment sensors or monitoring instruments; the third category is the online water quality parameter monitoring system. The advantage is that it can be used on a variety of platforms, such as ship-borne navigation platforms, fixed observation point platforms, etc., can support more types of sensors and monitoring instruments, and realize high-frequency real-time monitoring and data transmission; the main problem is that it is difficult to ensure monitoring The stability of long-term operation, including the influence of air bubbles generated by the sampling pump on sensor data, the influence of sedimentation on the flow path, and the influence of biological adhesion on sensor stability, etc.
