Description

Technical Field

[0001] The utility model belongs to the technical field of groundwater monitoring, and specifically belongs to an on-line water quality and water quantity monitoring system installed in a tube well. Background Technique

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality status, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand, and biochemical oxygen demand, etc.; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury, and organic pesticides, etc.; in order to objectively evaluate the water quality status of the tube well, in addition to the above monitoring items, the measurement of flow velocity and flow rate is sometimes required.

[0003] However, the existing water quality monitoring systems can only monitor single items and cannot monitor all of the above items. At the same time, when using the water quality monitoring system to conduct in-situ real-time monitoring of the water body in the tube well, the equipment is usually arranged in the tube well. Especially, the sensor needs to extend into the well body. During the long-term operation of the sensor, its lens will quickly be covered with dirt, seriously affecting the measurement accuracy. At present, it is cleaned manually regularly, which is very inconvenient. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide an on-line water quality and water quantity monitoring system installed in a tube well. The present application provides the following technical solutions:

[0005] An on-line water quality and water quantity monitoring system installed in a tube well includes a housing. Several interfaces are arranged at the top of the housing. A main control system and an automatic cleaning system are arranged in the housing. A water immersion sensor is arranged at the bottom of the housing. The main control system is respectively connected to the automatic cleaning system, several interfaces, and the water immersion sensor.

[0006] In a possible embodiment, several interfaces include a liquid level sensor interface, a flow velocity and flow rate sensor interface, a full-spectrum sensor interface, a power supply interface, and a communication module interface.

[0007] In a possible embodiment, a handle is arranged at the top of the housing.

[0008] In a possible embodiment, the automatic cleaning system includes an air inlet valve, an air inflation pump, an air storage tank, and an air inflation valve. The air inlet valve, the air inflation pump, the air storage tank, and the air inflation valve are connected in sequence. The main control system is respectively connected to the air inlet valve, the air inflation pump, and the air inflation valve. The air storage tank is arranged close to several interfaces.

[0009] In a possible embodiment, the main control system is an MCU control main board.

[0010] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0011] The online monitoring system of the present utility model is used for monitoring the water quality and quantity in pipe wells. Multiple sensors can be externally connected to its top. Through the control of the main control system, the full monitoring of the water quality, quantity, and water level information of the pipe network can be realized. For example, by connecting a full-spectrum sensor to monitor COD and ammonia nitrogen indicators, and connecting a liquid level sensor and a flow velocity and flow rate sensor, indicators such as the liquid level, flow velocity, and flow rate in the pipe well can be monitored. At the same time, the system can support the expansion of other types of sensors to monitor the corresponding water quality indicators, meeting the all-round monitoring requirements for pipe wells; at the same time, the system is equipped with an automatic cleaning system. Through the control of the main control system, the present utility model can achieve the function of high-pressure pneumatic self-cleaning. Combined with the fitted full-spectrum model, the sensors can operate automatically and be cleaned without manual maintenance under the water quality conditions of high pollution in the sewer pipe network.

The air storage tank 10 is arranged close to the plurality of interfaces; the main control system is an MCU control board 7.

[0023] In the above embodiment, as Figure 1As shown in the figure, it is a structural schematic diagram of the present utility model. The on-line water quality and water volume monitoring system of the present utility model includes a housing 1. The housing 1 is cylindrical. Inside the housing 1, a main control system and a self-cleaning system are installed. The main control system includes an MCU control main board 7 and a power control and management system. The power control system is used to supply power to the entire system and, through the setting of the MUC control main board, comprehensively control the power distribution of the entire system, saving unnecessary power consumption. In the low-power mode, the average power consumption of the whole machine of the system is less than 0.5W. The self-cleaning system includes an air inlet valve 8, an air inflation pump 9, an air storage tank 10, and an air inflation valve 11 installed inside the housing 1 from bottom to top. Both the air inlet valve 8 and the air inflation valve 11 are solenoid valves. At the top of the housing 1, a plurality of interfaces are provided, including a liquid level sensor interface 2, a flow velocity and flow sensor interface 3, a full-spectrum sensor interface 4, a power supply interface 5, and a communication module interface 6. They are respectively externally connected to a hydraulic sensor, a flow velocity and flow sensor, a full-spectrum sensor, an external power supply, and a 4G communication module, and are all connected to the main control system. At the same time, a water immersion sensor 12 is also provided at the bottom of the housing 1. The water immersion sensor 12 is used to detect the environment around the housing 1, can sense the environment where the device is located, and enables the system to adapt to various harsh external environments such as waterlogging, high temperature and high humidity.

[0024] As Figure 2 shown, when in use, a chain is installed at the top of the pipe well. The chain can be wound around the handle 13 at the top of the housing 1.

[0025] As Figure 3 shown, when in use, the MCU control main board 7 can, through setting, read the data of each sensor in real time or at regular intervals. The MCU control main board 7 then uploads the data to the cloud service platform through the 4G communication module. At the same time, the cloud service platform can also remotely set system parameters, calibrate sensor data, etc. through the 4G communication module to achieve long-distance monitoring and control of the system; the MCU control main board 7 can also automatically clean the lens of the sensor according to the set parameters and the operating status of the sensor. The specific automatic cleaning process is as follows: Detect the status of the water immersion sensor 12. If the system is in a waterlogging state, the system does not enter the cleaning mode. If the device is not in a waterlogging state, the system opens the air inlet valve 8; after opening the air inlet valve 8, the air inflation valve 11 is delayed to be opened to equalize the pressure of the system, and then the air inflation valve 11 is closed and the high-pressure air inflation pump 9 is opened to pressurize the air storage tank 10. After the air pressure in the air storage tank 10 reaches 0.4 MPa, the air inflation valve 11 is opened to release the pressure of the air storage tank 10 to perform high-pressure flushing on the lens of the sensor.
