Description
Technical Field
[0001] The utility model belongs to the field of water quality detection auxiliary equipment, and particularly relates to a remote automatic well washing and water quality monitoring device. Background Art
[0002] Well washing is an essential step before groundwater sampling. Sampling can only be carried out after the water quality parameters and water level are stable to ensure reliable data. The traditional well washing method is that workers use a bailer or a water pump to lower into the well to pump out the well water until the well washing water volume reaches 3 - 5 times the well volume, and use a water quality detector outside the well to detect the water quality parameters of the pumped well water. After the water quality parameters reach the stable standard, well washing stops, and then sampling is carried out, and the sampling is detected and data is recorded. Before well washing, workers need to transport equipment such as power supplies, pumping equipment, and water quality detectors to the required well washing location manually. After well washing and sampling are completed, each equipment is withdrawn. Moreover, the well washing process causes great disturbance to the water body in the well, affecting the accuracy of water body parameter measurement. The degree of manual participation is high, the working process is cumbersome, time-consuming and laborious, and the automation degree is extremely low. Content of the Utility Model

Detailed implementation manners
[0017] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments:
[0018] Embodiment 1, as Figure 1-2 shown, a remote automatic well washing and water quality monitoring device includes a mounting frame 1 and a water pumping device. The key is that the remote automatic well washing device further includes a data storage unit 6. A control unit 2 and a power supply unit 3 are arranged on the mounting frame 1. The water pumping device includes a water pump 5 located in the well. A water body parameter monitoring unit 4 is also arranged in the well. The water pump 5 and the water body parameter monitoring unit 4 are respectively controlled and connected to the control unit 2, and the water body parameter monitoring unit 4 is signal-connected to the control unit 2. The control unit 2 is signal-connected to the data storage unit 6. The power supply unit 3 is electrically connected to the water pump 5, the water body parameter monitoring unit 4, the control unit 2, and the data storage unit 6 respectively.
[0019] The control unit 2 and the power supply unit 3 are integrated on the mounting frame 1. Among them, the power supply unit 3 provides electrical energy for the control unit 2, the water pump 5, the water body parameter monitoring unit 4, and the data storage unit 6. The control unit 2 controls the switches of the water pump 5 and the water body parameter monitoring unit 4, and can realize automatic well washing and monitoring of water body parameters. The water body parameter monitoring unit 4 sends the monitored parameters to the control unit 5. The control unit 2 sends the parameter signals to the data storage unit 6 and stores and records the monitoring data with the help of the data storage unit 6. Once the device is transported and installed, automatic well washing and automatic sampling and analysis can be realized through the control of the control unit 2, without too much manual intervention, saving time and effort. Moreover, the water body parameter monitoring unit 4 is located in the well and directly monitors the water body in the well, ensuring the effectiveness and real-time nature of the data, realizing in-situ real-time online monitoring of various water body parameters, and can long-term monitor the parameters of groundwater and automatically store the monitoring data, supporting dynamic analysis of the water sample data of groundwater, providing data support and decision-making basis for mastering the change law of groundwater, understanding the current situation of groundwater exploitation, and guiding the protection of groundwater resources.
[0020] Among them, the water body parameter monitoring unit 4 is located above the water pump 5. The water pump 5 pumps water out of the well. The water body parameter monitoring unit 4 is a commercially available and mature monitoring device, such as a multi-parameter water quality electrode. The water body parameter monitoring unit 4 is always located below the water level and can directly and real-time measure various parameters of the water body in the well in-situ, including water level, temperature, pH value, ORP, conductivity, turbidity, dissolved oxygen, chloride, ammonia nitrogen, nitrate nitrogen, oxygen consumption, total dissolved solids, or also including oil in water, improving the monitoring accuracy and continuity. The water pump 5 is an airbag pump. The airbag pump with a lower flow rate continuously washes the well in the well, which can reduce the disturbance of the water body in the well and further improve the accuracy of the detection by the water body parameter monitoring unit 4. During the well washing process, when the water level drops by more than the maximum set drop height, the control unit 2 controls the water pump 5 to pause the well washing. After the water level is replenished, the water pump 5 is restarted to wash the well; in this embodiment, the maximum set drop height is 10 cm. Since the water body parameter monitoring unit 4 is located above the water pump 5 and the water pump 5 pumps water from below its pump body, the water level at the location of the water body parameter monitoring unit 4 changes with the pumping of the water pump 5. At the same time, the groundwater outside the well seeps into the well, and the water gradually floods into the location of the water body parameter monitoring unit 4, with less influence from the pumping of the water pump 5, further reducing the disturbance of the water body at the location of the water body parameter monitoring unit 4 and ensuring the real-time and accuracy of the monitoring data.
[0021] The installation frame 1 includes a base 11, a control cabinet 12 arranged on the base 11, and an installation skeleton 13 located outside the control cabinet 12. The control unit 2 and the battery pack 32 are respectively located inside the control cabinet 12 to prevent the influence of rain and sunlight on the service life of the control unit 2 and the battery pack 32; the photovoltaic panel 31 is installed by means of the installation skeleton 13 and is located above the control cabinet 12. The projected area of the photovoltaic panel 31 in the horizontal direction is larger than the projected area of the base 11. The photovoltaic panel 31 shields the control cabinet 12, increasing the area of the photovoltaic panel 31 to improve the power supplemented by the photovoltaic panel 31 to the battery pack 32, and at the same time shielding the control cabinet 12 to further reduce the control cabinet 12 from being exposed to rain and sunlight.
[0022] The data storage unit 6 includes a remote signal receiver 61 and a data memory 62 arranged on the installation frame 1. The remote signal receiver 61 and the data memory 62 are respectively signal-connected to the control unit 2. The control unit 2 stores the data in the data memory 62 and transmits the data to the remote signal receiver 61 regularly by means of a wireless router, and can also give an alarm plus report or make up a report in case of network interruption when the data is abnormal. In case of power failure or network interruption, the data memory 62 can retain the detection data, effectively preventing the loss of monitoring data.
[0023] The described power supply unit 3 includes a photovoltaic panel 31 located outside the mounting frame 1 and a battery pack 32 located inside the mounting frame 1 and connected to the photovoltaic panel 31. The battery pack 32 is electrically connected to the water pump 5, the water body parameter monitoring unit 4, and the control unit 2 respectively. A surge protector is provided in the connection circuit between the battery pack 32 and the water pump 5, the water body parameter monitoring unit 4, and the control unit 2 to prevent lightning from damaging the water pump 5, the water body parameter monitoring unit 4, the control unit 2, etc.; the battery pack 32 provides electrical energy for the control unit 2, the water pump 5, the water body parameter monitoring unit 4, and the data storage 62 to ensure continuous well washing, water body parameter monitoring, and storage of monitoring data. The photovoltaic panel 31 receives sunlight and converts solar energy into electrical energy to replenish the power of the battery pack 32, enabling the device to adapt to field well washing and sampling operations, with a wider range of applicable sites, and can realize long-term monitoring of groundwater parameters and automatic storage of monitoring data. The battery pack 32 can be selected as a gel battery.
[0024] The control unit 2 includes a main controller, a photovoltaic controller, and a water pump controller. The main controller realizes the charging of the battery pack 32 by the photovoltaic panel 31 by issuing instructions to the photovoltaic controller, and conducts automatic well washing by issuing instructions to the water pump controller. At the same time, the main controller is responsible for data collection and data transmission to realize automatic well washing, sampling operations, and data retention.
[0025] Embodiment 2, as Figure 3 shown, this embodiment is basically the same as Embodiment 1, except that the water pump 5 and the water body parameter monitoring unit 4 are both located inside the sleeve 7 and are installed in the well by means of the sleeve 7. The upper end of the sleeve 7 is provided with a water outlet hole 71 of the water pump 5, and the lower end of the sleeve 7 is provided with a water inlet 72 with a diameter smaller than the diameter of the sleeve 7 barrel. A group of water seepage holes 73 are provided on the side wall of the sleeve 7. In this embodiment, the water pump 5 and the water body parameter monitoring unit 4 are connected and integrated by means of the sleeve 7, and the relative positions of the water pump 5 and the water body parameter monitoring unit 4 are fixed. The water pump 5 and the water body parameter monitoring unit 4 can be lowered into the well at the same time with one operation, reducing the probability of collision with the well wall; at the same time, the water pump 5 and the water body parameter monitoring unit 4 are located in the same sleeve 7. When the water pump 5 pumps water, pressure is generated inside the sleeve 7, forcing the water in the well to enter the sleeve 7. The water seepage holes 73 enable the water to enter the sleeve 7 evenly along the side wall of the sleeve 7, ensuring that the water volume inside the sleeve 7 is always sufficient; on the other hand, the water in the well enters the sleeve 7 in a dispersed state for the water pump 5 to pump, further reducing the disturbance of the water body in the well during the pumping process. The water body in the well where the water body parameter monitoring unit 4 is located enters the sleeve 7 from the side wall, passes through the water body parameter monitoring unit 4, and then moves downward and is pumped away by the water pump 5, enabling the water body at the location of the water body parameter monitoring unit 4 to flow and be updated in a timely manner, ensuring that the water body parameter monitoring unit 4 can perform accurate in-situ monitoring.
