[0031] Example 1

[0032] Please refer to Figure 1 The present embodiment provides a device for monitoring the content of organic fluoride in surface water, comprising a liquid storage tank 1 for storing water samples, an infusion device 2 and a detection device 3; the liquid storage tank 1 is provided with a plurality of liquid inlet pipes 4 connected to the liquid storage tank 1; the plurality of liquid inlet pipes 4 all extend downward and have different lengths; the liquid storage tank 1 is provided with a power mechanism for extracting water samples; one end of the infusion device 2 is connected to the liquid storage tank 1, and the other end of the infusion device 2 is connected to the detection device 3.

[0033] In this embodiment, the monitoring device for the content of organic fluoride in surface water can be set in certain lakes, the liquid storage tank 1 is located above the water surface, and the ends of all the liquid inlet pipes 4 are suspended in the water. The power mechanism extracts water samples into the liquid storage tank 1, and only one liquid inlet pipe 4 is used for each extraction. Each liquid inlet pipe 4 has a different length, which ensures that the water sample extracted each time belongs to only a certain water layer, and there will be no water sample mixing. The extracted water sample is transported to the detection device 3 through the infusion device 2, and the detection device 3 detects the fluoride in the water sample. The whole process does not require manual operation. The detection device 3 can be an automatic fluoride ion monitor.

[0034] In this embodiment, the power mechanism includes a blowing and sucking dual-purpose air pump 5 and an air duct 6, one end of the air duct 6 is connected to the liquid storage tank 1, and the other end of the air duct 6 is connected to the blowing and sucking dual-purpose air pump 5; the blowing and sucking dual-purpose air pump 5 is arranged in the liquid storage tank 1.

[0035] In detail, the air pump 5 is located on the upper end surface of the liquid storage tank 1, the air guide pipe 6 extends into the liquid storage tank 1, and the air pump 5 is provided with an exhaust pipe 24, one end of the exhaust pipe 24 is connected to the air pump 5, and the other end of the exhaust pipe 24 is provided with an exhaust valve 25. When extracting water samples, the air pump 5 extracts the air inside the liquid storage tank 1, the exhaust valve 25 opens, and the air in the liquid storage tank 1 is finally discharged from the exhaust pipe 24. At this time, the air pressure in the liquid storage tank 1 is lower than the atmospheric pressure, and under the action of the atmospheric pressure, the water sample enters the liquid storage tank 1 from the liquid inlet pipe 4.

[0036] In this embodiment, if Figure 2 and Figure 3 As shown, the power mechanism also includes a first motor 7, a first connecting rod 8 and a turntable 9; the first motor 7 is arranged in the liquid storage tank 1, one end of the first connecting rod 8 is connected to the rotating shaft of the first motor 7, and the other end of the first connecting rod 8 is connected to the turntable 9; the first connecting rod 8 and the turntable 9 are both located inside the liquid storage tank 1; the turntable 9 abuts against the bottom of the liquid storage tank 1, and the central axis of the turntable 9 is collinear with the central axis of the liquid storage tank 1. The turntable 9 is provided with a liquid collection hole 10 that passes through the turntable 9; the central axis of the liquid collection hole 10 is vertical; the distance from the central axis of the liquid collection hole 10 to the central axis of the turntable 9 is the same as the distance from the central axis of any liquid inlet pipe 4 to the central axis of the liquid storage tank 1.

[0037] In detail, the turntable 9 rotates, and when the liquid collection hole 10 is aligned with the liquid inlet pipe 4, the water sample can enter the liquid storage tank 1 from the liquid inlet pipe 4; when the liquid collection hole 10 is offset from the liquid inlet pipe 4, the turntable 9 has a sealing effect on the liquid inlet pipe 4. Before extracting the water sample, the turntable 9 seals the liquid inlet pipe 4, and the blowing and suction dual-purpose air pump 5 blows air into the liquid storage tank 1 to make the air pressure inside the liquid storage tank 1 greater than the external air pressure, that is, before extracting the water sample, the air pressure inside the liquid storage tank 1 is greater than the external air pressure. When extracting the water sample, the rotating shaft of the first motor 7 rotates, and the turntable 9 rotates, so that the liquid collection hole 10 is aligned with the liquid inlet pipe 4. At this time, the air pressure inside the liquid storage tank 1 is relatively large, and the lake water will not enter the liquid storage tank 1 from the liquid inlet pipe 4. The blowing and suction dual-purpose air pump 5 sucks air into the liquid storage tank 1, and the air pressure inside the liquid storage tank 1 decreases. Under the action of atmospheric pressure, the water sample enters the liquid storage tank 1. A liquid level sensor 26 is provided inside the liquid storage tank 1. When the water sample in the liquid storage tank 1 submerges the liquid level sensor 26, the blowing and suction dual-purpose air pump 5 stops working, and the turntable 9 rotates again to seal the liquid inlet pipe 4.

[0038] It should be noted that the number of the liquid inlet pipes 4 can be 3, and the liquid inlet pipes 4 are evenly arranged in the circumferential direction, and the angle of each rotation of the turntable 9 can be 60 degrees, so as to ensure that the liquid collection hole 10 of the turntable 9 can be accurately aligned with the liquid inlet pipe 4. When the turntable 9 is rotated, the internal air pressure of the liquid storage tank 1 is always greater than the external air pressure, and there is no need to worry that the water sample enters the liquid storage tank 1 when the turntable 9 rotates, causing problems in the detection of the water sample.

[0039] In detail, the first connecting rod 8, the second connecting rod 13 and the connection between the air guide tube 6 and the liquid storage tank 1 are all provided with sealing devices to ensure the good air tightness of the liquid storage tank 1, and the air pressure in the liquid storage tank 1 can change normally when the dual-purpose air pump 5 blows or inhales air into the liquid storage tank 1. If there is no sealing device, when the dual-purpose air pump 5 blows or inhales air into the liquid storage tank 1, the air pressure inside the liquid storage tank 1 changes little, resulting in the inability to extract or discharge water samples.

[0040] In the present embodiment, the turntable 9 is provided with a filter screen 11 for filtering impurities in the water sample, and the filter screen 11 is provided at the liquid collection hole 10. Considering that there are many impurities in the lake water, the water sample needs to be filtered when extracting the water sample. Because the organic fluoride content detection equipment in surface water of the present invention has no manual operation process, and the extraction of water samples is fully automated, if there is no filter screen 11, large particles of impurities will enter the liquid storage tank 1, and the impurities may block the infusion tube 17, resulting in interruption of the transportation of the water sample. Impurities may also enter the gap at the connection between the turntable 9 and the liquid storage tank 1. In the mild case, it will cause the first connecting rod 8 to rotate more laboriously and increase energy consumption; when the impurity blockage is serious, it will cause the turntable 9 to get stuck.

[0041] In this embodiment, it also includes a second motor 12, a second connecting rod 13 and a propeller 14; the second motor 12 is arranged in the liquid storage tank 1, one end of the second connecting rod 13 is connected to the rotating shaft of the second motor 12, and the other end of the second connecting rod 13 is connected to the propeller 14; the second connecting rod 13 and the propeller 14 are both located inside the liquid storage tank 1.

[0042] In detail, the interior of the liquid storage tank 1 needs to be cleaned regularly, and the liquid used for cleaning is stored in the cleaning tank 16. When cleaning the liquid storage tank 1, the cleaning liquid enters the liquid storage tank 1. At this time, the turntable 9 seals the liquid inlet pipe 4, and the propeller 14 is immersed in the cleaning liquid. When the cleaning liquid reaches the liquid level sensor 26, the cleaning liquid stops entering, and the propeller 14 is vertically lower than the liquid level sensor 26 to ensure that the propeller 14 can be immersed in the cleaning liquid.

[0043] After the input of the cleaning liquid stops, the second motor 12 rotates, and the second connecting rod 13 drives the propeller 14 to rotate. The propeller 14 stirs the cleaning liquid inside the liquid storage tank 1. The second motor 12 rotates for at least 10 minutes to ensure that the cleaning liquid can clean most of the inner wall of the liquid storage tank 1. During the cleaning period, the internal air pressure of the liquid storage tank 1 is the same as the external air pressure. To make the internal and external air pressures of the liquid storage tank 1 the same, the exhaust valve 25 needs to be opened, and the external gas automatically enters the liquid storage tank 1 from the exhaust pipe 24 and the air guide pipe 6. After the cleaning is completed, the rotating shaft of the first motor 7 drives the turntable 9 to rotate so that the liquid collection hole 10 is aligned with the liquid inlet pipe 4, and the cleaning liquid is automatically discharged from the liquid inlet pipe 4 under the action of gravity. After the cleaning liquid is discharged, the water sample extracted by the power mechanism cannot be directly tested, and there may be residual impurities inside the liquid storage tank 1, so the cleaning process needs to be continued for multiple times to ensure that the impurities in the liquid storage tank 1 disappear. The cleaning liquid can be pure water.

[0044] In this embodiment, the liquid storage tank 1 is provided with a protective cover 15; the blowing and suction dual-purpose air pump 5, the first motor 7 and the second motor 12 are all located inside the protective cover 15. The protective cover 15 mainly plays the role of waterproofing and sun protection. Since the first motor 7, the second motor 12 and the blowing and suction dual-purpose air pump 5 are electrical components, electrical components are very likely to short-circuit when they come into contact with water, thereby causing the entire sampling and detection process to collapse. If there is no protective cover 15, the first motor 7, the second motor 12 and the blowing and suction dual-purpose air pump 5 are in a sun environment for a long time, and they may become hot, and in severe cases, they may burn out.

[0045] In this embodiment, a cleaning tank 16 storing cleaning liquid is also included; the infusion device 2 includes an infusion tube 17 and a three-way tube 18; one end of the infusion tube 17 is connected to the liquid storage tank 1, and the infusion tube 17 is connected to one of the pipes of the three-way tube 18; the other two pipes of the three-way tube 18 are respectively connected to the cleaning tank 16 and the detection device 3. An air guide hole 23 is provided at one end of the cleaning tank 16 away from the three-way tube 18, and the air guide hole 23 passes through the cleaning tank 16. Each pipe of the three-way tube 18 is provided with a solenoid valve 19.

[0046] In this embodiment, if Figure 1 and Figure 2 As shown, when extracting water samples, the electromagnetic valves 19 of the three-way pipe 18 are all in a closed state, and the internal chambers of the liquid storage tank 1 and the internal chambers of the infusion device 2 are in a closed state. At this time, the liquid collection hole 10 is aligned with the liquid inlet pipe 4, and the blowing and suction dual-purpose air pump 5 sucks air into the liquid storage tank 1, and the air pressure inside the liquid storage tank 1 decreases. Under the action of atmospheric pressure, the water sample enters the liquid storage tank 1, and a part of the water sample flows into the infusion pipe 17. When the water sample submerges the liquid level sensor 26, the turntable 9 rotates to seal the liquid inlet pipe 4, the electromagnetic valve 19 at the connection between the three-way pipe 18 and the liquid storage tank 1 and the detection device 3 is opened, and the electromagnetic valve 19 at the connection between the three-way pipe 18 and the cleaning tank 16 is closed, and the blowing and suction dual-purpose air pump 5 blows air into the liquid storage tank 1, and the air pressure inside the liquid storage tank 1 increases, forcing the water sample to enter the detection device 3 from the infusion device 2, and the detection device 3 can detect the water sample at this time.

[0047] When the liquid storage tank 1 is cleaned, the air pressure inside the liquid storage tank 1 is the same as the external air pressure. To make the air pressure inside and outside the liquid storage tank 1 the same. At this time, the solenoid valve 19 at the connection between the three-way pipe 18 and the liquid storage tank 1 and the cleaning tank 16 is opened, and the solenoid valve 19 at the connection between the three-way pipe 18 and the detection device 3 is closed. The air guide hole 23 ensures that the air pressure inside the cleaning tank 16 is the same as the external air pressure, and the exhaust valve 25 is opened, and the external gas enters the liquid storage tank 1. At this time, the cleaning liquid flows into the liquid storage tank 1 through the infusion tube 17. When the cleaning liquid submerges the liquid level sensor 26, the solenoid valve 19 at the connection between the three-way pipe 18 and the cleaning tank 16 is closed, and the second motor 12 drives the propeller 14 to rotate, and the propeller 14 stirs the cleaning liquid inside the liquid storage tank 1, and the cleaning liquid cleans the liquid storage tank 1. After the cleaning is completed, the turntable 9 rotates, and the cleaning liquid is automatically discharged from the liquid inlet pipe 4 under the action of gravity.

[0048] In this embodiment, if Figure 4 As shown, it also includes a control device 22; the control device 22 includes a control module, a wireless transmission module, a control terminal and a power supply; the first motor 7, the second motor 12, the blowing and suction dual-purpose air pump 5, the solenoid valve 19, the detection device 3, the wireless transmission module and the power supply are all electrically connected to the control module; the wireless transmission module is wirelessly connected to the control terminal. The wireless transmission module can be a wifi module or a Bluetooth module, the control terminal can be a mobile phone, the model of the solenoid valve 19 can be a 2W160-15 solenoid valve, and the model of the control module can be AT89C51.

[0049] In detail, the operations of the first motor 7, the second motor 12, the blowing and suction dual-purpose air pump 5, the solenoid valve 19 and the detection device 3 are all controlled by the control module and can be performed automatically. The cleaning tank 16, the detection device 3 and the control device 22 are all located on the shore. If the cleaning tank 16 is located in the water, a corresponding bracket needs to be set to fix the cleaning tank 16 to prevent the cleaning tank 16 from being seriously corroded by being immersed in water for a long time. The infusion tube 17 can be a flexible tube, and the infusion tube 17 can float horizontally on the water surface. If the infusion tube 17 is made of hard material and the infusion tube 17 is long, the infusion tube 17 is easy to break under the action of water waves.

[0050] The power source can be electric energy generated by solar energy or wind power generation. The operator needs to set up solar panels or small wind turbines, power conversion devices and batteries on the shore. The energy collected by the solar panels or small wind turbines is converted into electric energy by the power conversion device and stored in the battery. The battery supplies power to the first motor 7, the second motor 12, the blowing and suction dual-purpose air pump 5, the electromagnetic valve 19 and the detection device 3.

[0051] In this embodiment, the liquid storage tank 1 is provided with a plurality of support frames 20; one of the support frames 20 is provided with a buoy 21. The support frame 20 fixes the liquid storage tank 1 and is higher than the lake surface. If the liquid storage tank 1 is immersed in the lake, the lake water is likely to damage the first motor 7, the second motor 12 and the blowing and suction dual-purpose air pump 5. If the liquid storage tank 1 is in a floating state, the infusion tube 17 is likely to be pulled by the liquid storage tank 1, and in severe cases, the infusion tube 17 will be broken.
