Description

A floating device for water quality and hydrological monitoring in small and medium water areas

technical field

The invention relates to an online water quality monitor, which belongs to the technical field of environmental protection monitoring instruments, and in particular to the improvement and innovation of water quality and hydrological monitoring devices for small and medium reservoirs, lakes and the like.

Background technique

After entering the 21st century, my country vigorously promotes environmental monitoring, especially in the aspect of water environment monitoring. However, the existing domestic water quality and hydrological monitoring devices have single functions, small amount of data information, and irregular structural design, which cannot be systematically targeted at specific water quality problems. It is difficult to keep up with the rapid development of water quality monitoring with intelligent analysis and processing, remote monitoring and control. In this regard, someone has proposed a multifunctional water quality monitor to expect to solve the above problems (referring to Chinese Invention Patent Publication No. CN89200668), although this "MF-10 type multifunctional water quality monitor" is a portable hydrological water quality monitor. The analyzer can obtain the engineering value of the current water quality parameters by reading numbers, but this instrument can only detect four fixed water sample parameters (temperature, acidity, conductivity and salt content), and cannot transmit data through wireless transmission. It is difficult to realize networking, real-time and remote monitoring. Chinese Invention Patent Publication No. CN1291723 "Intelligent Water Quality Comprehensive Monitoring Instrument" integrates multiple water quality detection sensors on one instrument, and reads various data in sequence. However, this instrument has a single communication method and is difficult to use in harsh environments. Time enters the water to work, and at the same time, various data can only be monitored sequentially, not at the same time, and the monitoring parameters are fixed. Another example is the Chinese invention patent publication number CN202204534U of a lake water quality remote monitoring, analysis and water bloom forecasting and early warning intelligent system. , cost a lot. In terms of engineering, different monitoring points are distributed in different regions. Different monitoring points need to monitor different parameters and use different types of monitoring equipment. For different data, data classification and comprehensive mathematical statistics must be carried out in terms of time and space. Time consuming. In practice, what the water quality and hydrological monitoring system expects to achieve is standardization, integration, miniaturization, and simplification. A single device can meet the collection of different water quality parameters, and realize the monitoring of hydrological data with an economical system. Simple, Safe way to implement multipoint distribution.

In view of the above deficiencies in the prior art, the purpose of the present invention is to break through the limitations of traditional water quality monitoring instruments, make up for the deficiencies of existing equipment, and provide a real-time, accurate, easy to install, low cost, flexible and small one for small and medium reservoirs, Floating devices for lakes and other water quality and hydrological monitoring.

For this reason, the technical scheme that the present invention uses is:

A floating device for water quality and hydrological monitoring in small and medium-sized water areas, consisting of a central monitoring platform and a buoyancy support mechanism. The buoyancy support mechanism is three stainless steel spherical buoyancy balls connected with the central monitoring platform; the central monitoring platform also has a sealed stainless steel central cavity Body, data acquisition equipment, communication module and central processing module are placed in the central cavity, and more than one surrounding tube is arranged outside the central cavity, and a sensing probe in contact with the measured water surface is arranged in the surrounding tube, and the sensing probe and The data acquisition device is electrically connected.

The data acquisition equipment includes electromechanical sensors such as liquid level sensors, PH measuring instruments, thermometers, and rain gauges; the data acquisition equipment and communication equipment are powered by intermittent batteries, and the batteries are in sleep mode when there is no data transmission, and have a wake-up mechanism. The huge structure brought by the solar panel. The first serial peripheral interface of the central processing module communicates with the output end of the front sensor, and the second serial peripheral interface communicates with the input end of the lower communication module.

Owing to taking above-mentioned technical improvement, the present invention has following advantage:

The newly designed floating station has the advantages of simple and convenient layout, no geographical restrictions, and no damage to the ecological environment of the monitoring station. The stainless steel balls are waterproof and anti-corrosion, lightning-proof and surge-proof, achieving beautiful appearance, reasonable structure, miniaturization of the station, Features of standardization and integration.

The newly designed battery is used for power supply, and at the same time, the balance between power saving and volume is achieved. The battery with a wake-up mechanism can serve the system for up to three years, eliminating the problem of expensive and bulky solar panels.

A single device with multiple data acquisition sensors is used to realize multiple parameters at a single point, saving time, effort and money. One monitoring site can collect multi-hand data in real time, which is truly convenient, flexible, and low-cost.

Detailed ways

The present invention will be described below in conjunction with the accompanying drawings. As can be seen from Fig. 1 to Fig. 3, the floating device of the present invention is composed of a central monitoring platform and a buoyancy support mechanism, and the buoyancy support mechanism is three stainless steel sphere buoyancy balls 10, 20 connected with the central monitoring platform. , 30 components. In this way, the functional module and the buoyancy module are separated to work independently, waterproof and anti-corrosion, and lightning-proof and surge-proof.

The central monitoring platform 100 also has a sealed stainless steel central cavity, and the data acquisition equipment, communication module and central processing module are placed in the central cavity, and more than one surrounding pipe is arranged outside the central cavity. In this embodiment, two Surrounding pipes 110 and 120, the surrounding pipes are provided with sensing probes in contact with the measured water surface, the collection of sensing probes constitutes the data acquisition equipment, and the lead wires of the data acquisition equipment are connected to the central cavity by the upper end of the surrounding pipes With the central processing module 140, the processing signal forms a communication connection with the cloud system through the communication module 150 and the antenna 130.
