The quality of the aquaculture water environment is directly related to the growth and development of the aquaculture animals, and thus to the yield, quality and economic benefits of the aquaculture industry. Therefore, the water quality is required to be monitored during the aquaculture so as to control and adjust the aquaculture water quality in time and provide a high-quality growing water environment for the aquatic products. Particularly in a high-density intensive farm, the water quality is high in degradation speed due to high cultivation density, and irrecoverable large loss is easy to cause, so that high-frequency and even real-time monitoring is needed for the water quality, and the water quality is regulated in real time according to the monitoring result, so that the cultivation loss caused by water quality degradation is reduced.
At present, the traditional water quality monitoring method is characterized in that manual fixed-point sampling and laboratory off-line analysis are adopted; one is real-time on-line monitoring of water quality monitoring stations. The laboratory analysis method needs sampling, processes and re-measures, and the measurement result has high precision, but the sample is limited to be processed each time, and the time is long, and secondary pollution is caused; the real-time online monitoring of the water quality monitoring station is high in cost because of the establishment of the water quality monitoring station, the monitoring station occupies a large area, the installation mode of monitoring equipment is fixed, the monitoring station is not movable and needs to adopt commercial power, the monitoring place is affected by environmental factors, and the like, and the water quality monitoring station cannot be widely laid out in a large area.
The water quality monitoring station system adopting the commercial power can only be fixed at one point for measurement. However, in the actual seawater pond culture mode, the water body is stored in a relatively closed culture pond, and the freshness of the water body in the culture pond is maintained by a mode of changing water periodically, so that different water body positions in the whole culture pond have different water quality indexes, and the water quality parameters in the water body are unevenly distributed, so that the water quality monitoring station system measurement data adopting the mains supply cannot accurately represent the whole environment condition of the culture pond.
The utility model patent of China with the application number 201820347822.0 provides an aquaculture water quality monitoring device, which comprises a detection floating platform, wherein the left side and the right side of the detection floating platform are symmetrically provided with a stable floating platform, the inner cavity of the stable floating platform is horizontally provided with a supporting baffle, the bottom of the supporting baffle is provided with a counterweight cavity, and one side of the stable floating platform is provided with a feeding pipe communicated with the counterweight cavity. The bottom of the detection floating platform is provided with a detection cavity, and the sensing contact rod at the bottom of the water quality detection sensor stretches into the inner cavity of the detection cavity. In this technique, increase and decrease the counter weight raw materials through the inlet pipe in to the counter weight chamber, come adjusting device's weight to adjust the depth of sinking that detects the floating platform, further adjust the income water depth of the response contact rod of detecting the intracavity, and then detect the quality of water of different degree of depth. But the above-mentioned mode of adjusting the income water depth of response contact bar through adjusting device weight that this patent discloses can only monitor the quality of water between the heavy material of sinking depth when not adding the counter weight material and the heavy material of filling down the heavy material depth, can't monitor the quality of water of the heavy depth of sinking, and its monitoring scope is limited, leads to monitoring data can not accurate reaction breed pond whole quality of water environment. In addition, the increase and decrease of the weight material cannot be accurately controlled, and the water depth cannot be accurately adjusted. In addition, this technology does not disclose how to add the weight material into the weight chamber through the feed pipe, nor how to take out the weight-reduced material, so that the person skilled in the art cannot implement this technical solution only according to the description of the specification.
