Description

Technical Field

[0001] The present invention relates to the technical field of water environment detection, and in particular to an online monitoring device for water environment pollution. Background Art

[0002] Water is the source of life and an important foundation for the sustainable development of human society. However, with the acceleration of industrialization and urbanization, large amounts of industrial wastewater, domestic sewage, and agricultural non-point source pollution are discharged into water bodies, leading to increasingly serious water pollution problems. Water pollution not only disrupts the balance of the aquatic ecosystem and threatens the survival of aquatic organisms, but also directly affects human drinking water safety and health. Therefore, strengthening the control of water pollution and achieving real-time and accurate monitoring of water quality have become urgent needs in the current environmental protection field. In recent years, the state and society have attached great importance to water pollution control, continuously increasing investment and promoting the development of water quality monitoring technology. However, existing monitoring technologies and equipment still have some problems that need to be solved.

[0003] There are two prominent problems in the existing water quality monitoring process. On the one hand, many monitoring devices cannot detect water quality at different water depths. There is a clear stratification phenomenon in the vertical direction of the water body, and water quality parameters such as dissolved oxygen, pollutant concentration, and water temperature at different depths may vary greatly. For example, deep water bodies may contain higher concentrations of heavy metals and organic pollutants due to factors such as sediment release, while surface water bodies are easily affected by atmospheric deposition, surface runoff, etc. However, traditional monitoring devices can usually only sample and detect at a single depth or a limited depth, and cannot fully reflect the quality status of the entire water body, resulting in incomplete and inaccurate monitoring data, which is difficult to meet the needs of complex water environment monitoring. On the other hand, the existing technology cannot effectively collect and classify the collected samples. In actual monitoring, water samples at different water depths may need to be analyzed separately to determine the vertical distribution characteristics of the pollution. However, existing devices lack the function of targeted collection and classified storage of water samples at different depths. Water samples at different depths are often collected together, or samples cannot be accurately distinguished according to depth. This makes subsequent data analysis and pollution tracing difficult to carry out accurately, seriously affecting the effectiveness and practicality of the monitoring results, and thus restricting the targetedness and effectiveness of water environmental pollution control.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0024] The following describes an online monitoring device for water environment pollution according to an embodiment of the present invention with reference to the accompanying drawings.

The sample table 52 is disposed within the floatation chamber assembly 1, with the sample injection nozzle 551 positioned above the sample table 52. A waste sample outlet 53 is provided on the sample table 52, and a sample tube 54 is also provided on the sample table 52. A data cable 343 is provided on the sample collection tube 34, which is electrically connected to the sensor collection assembly 31 and the signal transmitter 41, respectively. A support frame 51 is provided at the bottom of the sample table 52, which is secured to the interior of the floatation chamber 13 by support legs 511.

[0027] Specifically, when the online water environment pollution monitoring device of the present application is in use, the floating box assembly 1 is first floated on the surface of the water body, and water samples of different depths are collected through the sample collection tube 34 with adjustable depth. The sample collection tube 34 sucks the water sample from its bottom. After collection, the water sample is transmitted to the sample tube 54 on the sample table 52 through the sample collection tube 34, which is convenient for the classification and storage of water samples, and convenient for subsequent docking personnel to take samples from the sample tube 54.

[0028] When collecting water samples, the water quality at the depth can be monitored in real time through the sensing collection component 31, and the data can be transmitted to the signal transmitter 41 in real time and to the external receiving device for real-time online monitoring of water quality.

[0029] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, a water collection pump 33 is provided at the lower end of the sample collection tube 34, and a collection port 331 is provided on the outside of the water collection pump 33; a counterweight dish 32 is provided at the bottom of the water collection pump 33, and the counterweight dish 32 is a dish-shaped structure with a thick middle part and a thin edge to reduce the interference of the water flow. In addition, the counterweight dish 32 can also pull the bottom of the floating box assembly 1 downward to prevent the floating box assembly 1 from being blown over by wind and waves.

[0030] Specifically, when collecting water samples, the water collection pump 33 works, collects water samples through the collection port 331, and transmits the water samples to the sample collection tube 34 for upward transmission. The counterweight plate 32 acts as a counterweight to the bottom of the sample collection tube 34, so that the sample collection tube 34 remains vertical during the process of collecting water samples. The water collection pump 33 is powered by the data cable 343, and the data cable 343 is connected to the battery 4 in the floating box 13 to power the water collection pump 33.

[0031] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the sensing and collecting component 31 is arranged at the bottom of the counterweight plate 32, including a glass cover 311, a collector 312 and an electric cylinder 316, wherein a hidden seat 317 is provided at the bottom of the counterweight plate 32, the glass cover 311 is slidably provided on the inner side of the hidden seat 317, a brush ring 314 is provided at the bottom of the hidden seat 317, and the collector 312 is provided on the inner side of the glass cover 311. It should be noted that the collector 312 can be one or more combinations of a camera and a variety of water body detection devices.

[0032] A collector rotating motor 313 is also provided inside the glass cover 311 to drive the collector 312 to adjust the working angle. An electric cylinder 316 is provided inside the counterweight plate 32 , and an output shaft of the electric cylinder 316 is connected to the glass cover 311 .

[0033] Specifically, when the sensor collection assembly 31 is operating, the collector 312 rotates the collection angle via the collector rotation motor 313. The collector 312 then transmits the collected signals to the signal transmitter 41 via the data cable 343. The glass cover 311 provides an isolated and waterproof working environment for the collector 312. When the surface of the glass cover 311 becomes dirty, the electric cylinder 316, via the push rod 315, periodically moves the glass cover 311 up and down. As the glass cover 311 moves in and out of the hidden seat 317, it comes into contact with the brush ring 314, cleaning the surface of the glass cover 311.

[0034] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, a collection depth adjustment mechanism 6 is provided between the sample collection tube 34 and the sample filling nozzle 551, comprising a capstan 61 and a sample transmission tube 64, wherein the capstan 61 is rotatably arranged inside the floating tank 13 through a capstan bracket 611, a hollow shaft 65 is provided in the middle of the capstan 61, the sample collection tube 34 is wound around the capstan 61, a second drive gear disc 63 is provided at the annular edge of the capstan 61, a capstan drive motor 62 is provided on one side of the capstan 61, a second drive gear 621 is provided on the capstan drive motor 62, and the second drive gear 621 is engaged with the second drive gear disc 63.

[0035] The output end of the sample collection tube 34 communicates with the interior of the hollow shaft 65. A sealed bearing 66 is provided at the bottom of the hollow shaft 65. One end of the sample transfer tube 64 is connected to the sealed bearing 66, while the other end of the sample transfer tube 64 is connected to the sample filling nozzle 551. A guide sleeve 342 is provided at the bottom of the floatation tank 13. The sample collection tube 34 vertically passes through the guide sleeve 342. A guide wheel 341 is provided above the guide sleeve 342. The guide wheel 341 and the guide sleeve 342 guide the sample collection tube 34 during length adjustment.

[0036] Specifically, when it is necessary to adjust the collection depth of the water sample, the capstan drive motor 62 drives the second drive gear 621 to rotate, and the second drive gear 621 drives the second drive gear 63 on the edge of the capstan 61 to rotate, thereby driving the capstan 61 to rotate. The rotation of the capstan 61 adjusts the sampling depth of the lower end of the sample collection tube 34.

[0037] The water sample in the sample collection tube 34 is transmitted to the hollow shaft 65 in the center of the capstan 61 , and the hollow shaft 65 and the sealed bearing 66 transmit the water sample to the sample transmission tube 64 , and finally to the sample filling nozzle 551 .

[0038] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, a switching turntable 55 is rotatably provided on the sample table 52 by setting a bearing 552. The top of the switching turntable 55 is connected to the sample filling nozzle 551. A transmission pump 57 is provided at the bottom of the switching turntable 55. The transmission pump 57 is connected to the switching turntable 55 by setting a rotating transmission tube 571. The bottom of the transmission pump 57 is connected to the sample transmission tube 64. It should be noted that the rotating transmission tube 571 is a pipeline that can rotate to transmit fluid, so that the switching turntable 55 can still receive water samples from the transmission pump 57 when it rotates.

[0039] A swivel drive motor 56 is provided below the switch swivel 55 , and a first drive gear 561 is provided on the output shaft of the swivel drive motor 56 . A first drive sprocket 562 is provided on the outer surface of the switch swivel 55 , and the first drive gear 561 and the first drive sprocket 562 are meshed with each other.

[0040] Specifically, the sample transfer tube 64 transfers the water sample to the transfer pump 57, the transfer pump 57 transfers the water sample to the switching turntable 55, the turntable drive motor 56 drives the first drive gear 561 to rotate, and then drives the first drive gear plate 562 on the outer surface of the switching turntable 55 to rotate, and then drives the switching turntable 55 to rotate.

[0041] After the switch rotatable seat 55 rotates, the sample filling nozzle 551 is driven to rotate. Figure 2As shown, the water sample collected each time is transferred to the corresponding sample test tube 54. Before switching to a new sample test tube 54 each time, the switching turntable 55 drives the sample filling nozzle 551 to the top of the waste sample outlet 53 to discharge the excess water sample in front of the sample transmission tube 64. When the sample transmission tube 64 is filled with new water sample, the switching turntable 55 drives the sample filling nozzle 551 to jump to the top of the new sample test tube 54, and then the sample filling nozzle 551 injects the water sample into the corresponding sample test tube 54.

[0042] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the floatation tank assembly 1 includes a floatation tank 13, a photovoltaic panel 11, and a battery 4. A tank cover 12 is provided on top of the floatation tank 13, the photovoltaic panel 11 is mounted on top of the tank cover 12, and the battery 4 is disposed within the floatation tank 13. The battery 4 is electrically connected to the photovoltaic panel 11. The bottom of the waste sample outlet 53 extends through the bottom of the floatation tank assembly 1, allowing waste water samples from the waste sample outlet 53 to be directly drained, reducing the load on the floatation tank 13. The photovoltaic panel 11 is connected to the battery 4 via a power cord 141 and a plug 14, facilitating later replacement and maintenance of the photovoltaic panel 11.

[0043] Specifically, when the floating box 13 floats on the water, it generates electricity through the photovoltaic panel 11, the photovoltaic panel 11 charges the battery 4, and the battery 4 uses the electrical energy for transmission by the signal transmitter 41, as well as for supplying electricity to the turntable drive motor 56, the winch drive motor 62, the transmission pump 57, the water collection pump 33, and the sensor collection component 31.

[0044] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the floating box assembly 1 is also provided with an anchor assembly 2, including a hanging ring 21, a pull rope 22 and an anchor 23, wherein the hanging ring 21 is provided on the floating box assembly 1, the pull rope 22 is connected to the hanging ring 21, and the anchor 23 is connected to the hanging ring 21, and the hanging ring 21, the pull rope 22 and the anchor 23 are all detachable structures.

[0045] Specifically, when the floating box 13 floats on the water surface, it is towed by the hanging ring 21, the pull rope 22 and the anchor 23 to prevent the floating box 13 from drifting away, so that the floating box 13 can collect water samples in a fixed water area.

[0046] In order to clearly illustrate the above embodiment, refer to Figure 1-Figure 4The specific operating principle of the online water pollution monitoring device of the present invention is as follows: When in use, the floating tank 13 is first floated on the surface of the water body. The floating tank 13 is towed by the hanging ring 21, the pull rope 22, and the anchor 23, so that the floating tank 13 can collect water samples within a fixed area. The floating tank 13 generates electricity through the photovoltaic panel 11, charging the battery 4. The battery 4 uses this energy to transmit the signal from the signal transmitter 41 and to supply electricity to the rotating seat drive motor 56, the winch drive motor 62, the transmission pump 57, the water collection pump 33, and the sensor collection assembly 31.

[0047] During the water sampling process, the capstan drive motor 62 drives the capstan 61 to rotate, which in turn drives the sample collection tube 34 in and out of the capstan 61, thereby adjusting the sampling depth at the lower end of the sample collection tube 34. During water sampling, the water collection pump 33 operates, collecting water samples through the collection port 331 and transferring them to the sample collection tube 34 for upward transmission. The water sample in the sample collection tube 34 is then transferred to the hollow shaft 65 at the center of the capstan 61. The hollow shaft 65 and sealed bearing 66 transfer the water sample to the sample transfer tube 64 and ultimately to the sample filling nozzle 551.

[0048] During this period, the rotating seat driving motor 56 drives the switching rotating seat 55 to rotate, and the rotation of the switching rotating seat 55 drives the sample filling nozzle 551 to rotate, such as Figure 2 As shown, each collected water sample is transferred to the corresponding sample test tube 54. Before switching to a new sample test tube 54, the switch rotatable seat 55 drives the sample filling nozzle 551 to the top of the waste sample outlet 53 to discharge the excess water sample in front of the sample transfer tube 64. When the sample transfer tube 64 is filled with the new water sample, the switch rotatable seat 55 drives the sample filling nozzle 551 to jump to the top of the new sample test tube 54. Then, the sample filling nozzle 551 injects the water sample into the corresponding sample test tube 54, waiting for the subsequent docking personnel to take samples from the sample test tube 54.

[0049] When collecting water samples, the collector 312 rotates the collection angle through the collector rotation motor 313, and the collector 312 transmits the collected signal to the signal transmitter 41 through the data cable 343. The signal transmitter 41 transmits it to the external receiving device for real-time online monitoring of water quality.

[0050] In summary, the online monitoring device for water environmental pollution of an embodiment of the present invention floats the device on the surface of the water body through a floating box assembly, and collects water samples at different depths through a sample collection tube with adjustable depth. When collecting water samples, the water quality at the depth can be monitored in real time through the sensor collection assembly, and real-time online monitoring is performed by sending it to a signal transmitter; after collection, the water sample is transmitted to the sample tube on the sample table through the sample collection tube, which is convenient for sample classification and convenient for subsequent docking personnel to take samples from the sample tube.

[0051] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
