Description

Onshore water quality monitoring device

This work is a water quality monitoring device installed on land. The device is equipped with a clean water storage tank, which can automatically rinse and soak the probe of the water quality sensor with clean water after the water quality detection is completed.

Nowadays, the aquaculture industry has entered into intelligent farming management, which can upload the water quality, weather, biology and management information collected by the monitoring platform to the cloud, use the big data database to comprehensively study and judge the status of the breeding pond, and integrate the control of bait feeders, cleaning machines, etc. Compared with the traditional management method, it saves a lot of labor costs. However, it is known that there are still many problems to be overcome in cloud monitoring, such as the high cost of the detector and the long-term storage of the detector. In the breeding pond, it needs to be cleaned and maintained from time to time.

Take cloud monitoring of dissolved oxygen in aquaculture ponds as an example. The cost of purchasing a dissolved oxygen sensor is quite expensive, but the dissolved oxygen sensor must be placed in the pool water for a long time, and its probe is easily polluted and affects the test results. Cleaning and maintenance will increase labor costs. If you want to use the detection results of the dissolved oxygen sensor to control the operation of the water tanker, although you can save hundreds of dollars in electricity bills at most per month, there is still a considerable gap with the original cost of purchasing the dissolved oxygen sensor. The traditional breeding industry is discouraged.

Furthermore, usually a group of water quality detectors are required in a breeding pond. Generally, the commercially available water quality detectors usually have multiple functions, which can detect temperature, dissolved oxygen, pH, redox potential and salinity, etc., and can The test results are automatically transmitted to the cloud platform, allowing users to view the water quality of each aquaculture pond through the Internet. The management is very convenient, and the price is relatively higher.

In addition to the high cost of commercial water quality detectors, the detector must still be placed in water for a long time, so that the probe will soon be covered with a layer of organisms such as algae and barnacles, which will affect the detection results. The experience of the author is that it needs to be cleaned every week, otherwise the detection value will gradually deviate, and professional maintenance personnel usually clean it once a month, which is quite different from the actual demand. If professional maintenance personnel are required to increase the cleaning frequency, It will greatly increase the maintenance cost of water quality monitoring.

In order to improve the problem that the known water quality detector is placed in the breeding pond for a long time, it is easy to attach the biological pollution probe, the author once imagined setting up a water quality detection box on land, and pumping the water from the breeding pond through the pipeline and transporting it to the detection box for detection After the detection is completed, the pool water is discharged from the detection box, and the probe is automatically cleaned with clean water to prolong the service life of the detector and increase the stability of detection.

However, in practice, in addition to multiple sensors, the onshore water quality testing box must also be equipped with a water level sensor to detect the water level and a drainage solenoid valve to control the drainage of the testing box to avoid excessive water level. Among them, the Clark electrode-type dissolved oxygen sensor used to detect the dissolved oxygen will consume oxygen during operation, and it must be accurately detected in the flowing water. Therefore, the detection box also needs to be equipped with a stirring impeller and a motor that can increase the dissolved oxygen. As a result, the structure of the whole set of onshore water quality detection boxes is relatively complicated and the manufacturing cost is increased.

If the traditional electrode-type dissolved oxygen sensor is replaced by a fiber-optic sensor, although the dissolved oxygen can be measured more accurately in still water, and the setting of the stirring impeller and motor is omitted, the price of the fiber-optic sensor is Twice as much as the electrode-type dissolved oxygen sensor, which cannot effectively reduce the manufacturing cost. Therefore, how to refine the structure of the land-based detection box, omit the components of the water level sensor, drain solenoid valve, stirring impeller and motor, while maintaining a continuous flow of water, automatic overflow of the pool water during measurement to avoid excessive water level, after measurement Functions such as automatic drainage of pool water and automatic sensor cleaning will make the land-based detection box more perfect, which will be the problems that the creators want to improve.

The purpose of this creation is to provide a water quality monitoring device installed on land.
