Description

Technical Field

[0001] This invention relates to the field of detection device technology, specifically to an online detection device and online monitoring method for reservoir water quality. Background Technology

[0002] Reservoir water quality analysis is a crucial means of assessing and monitoring reservoir water quality, and it plays a vital role in ensuring the sustainable use of water resources, maintaining ecological balance, and guaranteeing the safety of drinking water for the public. By testing and evaluating reservoir water quality, public awareness and participation in water resource protection can be increased.

[0003] In existing technologies, floating monitoring devices are commonly used for real-time monitoring of reservoir water sources. These devices utilize a float carrying various water quality sensors to monitor key parameters in the water in real time. These parameters include, but are not limited to, water temperature, pH value, dissolved oxygen, turbidity, conductivity, and concentration of harmful substances. The buoy, through its built-in wireless communication module, can transmit monitoring data to a remote data center in real time, allowing management personnel to promptly obtain water quality information and respond accordingly. This automated and intelligent monitoring method significantly improves the efficiency and accuracy of water quality monitoring. However, because the water quality detection probe is submerged for extended periods, impurities and other substances in the water can adhere to the probe's surface, interfering with the sensor's accurate perception of water quality parameters. This leads to data deviations, affecting not only the accuracy of water quality assessments but also potentially delaying the response to water pollution problems due to misjudgments, making it difficult to guarantee the long-term reliability of online reservoir water quality monitoring.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] An embodiment of the online water quality monitoring device for reservoirs according to the present invention is as follows: Figures 1 to 9 As shown.

[0021] An online water quality monitoring device for a reservoir includes a floating tower 100, a turntable 200, a pumping pipe 300, and at least one detection probe 400. The floating tower 100 is vertically oriented and floats on the water surface. The turntable 200 is a vertically oriented cylindrical structure with its lower end sealed. The turntable 200 is rotatably mounted on the lower end of the floating tower 100 and is located underwater. When the turntable 200 rotates around its own axis, the water inside it flows radially from the inside to the outside. The side of the turntable 200 closer to its central axis along the radial direction is called the "inner" side, and the side farther from its central axis is called the "outer" side. The detection probe 400 is fixedly mounted on the lower end of the floating tower 100 and located inside the turntable 200. A water pumping pipe 300 is vertically installed at the lower end of the floating tower 100. The water pumping pipe 300 passes vertically through the turntable 200 and is vertically extendable. A water passage hole 310 is provided on the water pumping pipe 300, which is located inside the turntable 200. A filter cylinder 320 is provided at the lower end of the water pumping pipe 300, and the filter cylinder 320 is connected to the water pumping pipe 300.

[0022] Furthermore, the water passage 310 is set on the side of the detection probe 400 in the vertical direction, so that the water entering the turntable 200 through the water passage 310 can directly reach the position of the detection probe 400, which facilitates the detection of the water depth at that point.

[0023] The floating tower 100 is equipped with ear plates 101, to which ropes are connected. By making the floating tower 100 have a large surface area and light weight, it provides greater buoyancy, allowing the entire detection device to float on the sea surface. The floating tower 100 is then secured to solid objects such as rocks in the water with ropes to prevent the entire detection device from drifting in the water.

[0024] In this embodiment, by setting up a floating tower 100, a turntable 200, a detection probe 400, and a pumping pipe 300 in coordination, when testing the water quality of the reservoir, the floating tower 100 is deployed to the reservoir monitoring area. The floating tower 100 floats vertically on the water surface, while the turntable 200, detection probe 400, and pumping pipe 300 at its lower end are all submerged underwater. The vertical extension length of the pumping pipe 300 is adjusted according to the monitoring requirements so that the filter cylinder 320 at the lower end of the pumping pipe 300 is at the target detection depth.

[0025] Then, the rotating disc 200 is driven to rotate, causing water to continuously drain from the inside out. During this drainage process, the water pipe 300 sends water at its designated depth through the water hole 310 into the rotating disc 200, allowing the detection probe 400 to detect the water at the depth corresponding to the lower end of the water pipe 300. The water entering the water pipe 300 is first filtered by the filter cartridge 320 to prevent impurities from entering the rotating disc 200. This creates a relatively sealed position for the detection probe 400 within the rotating disc 200, providing some protection and reducing the adverse effects of impurities on the probe, thus improving detection accuracy. Once water at the depth corresponding to the lower end of the water pipe 300 enters the rotating disc 200, multiple different detection probes 400 can be used to detect water quality parameters (such as water temperature, pH value, dissolved oxygen, turbidity, etc.) within the rotating disc 200. Furthermore, if it is necessary to monitor the water quality at other depths, simply adjust the vertical extension position of the pumping pipe 300 to move the filter cartridge 320 to the new target depth, and repeat the detection process of draining, filtering, absorbing, and delivering water to achieve continuous detection of water quality at different depths, thus expanding the detection range.

[0026] In a further embodiment, the pumping pipe 300 is a telescopic pipe, and a hydraulic telescopic rod 330 is installed inside the pumping pipe 300. The hydraulic telescopic rod 330 is arranged vertically and can extend and retract in the vertical direction. The upper and lower ends of the hydraulic telescopic rod 330 are connected to the floating tower 100 and the pumping pipe 300, respectively. A driving component is provided on the floating tower 100 to drive the hydraulic telescopic rod 330 to extend and retract in the vertical direction. The driving component is prior art and can be a hydraulic cylinder.

[0027] The pumping pipe 300 includes multiple telescopic sections 340, which are arranged sequentially in the vertical direction, with adjacent telescopic sections 340 slidingly engaged. The telescopic section 340 closest to the detection probe 400 in the vertical direction is referred to as the first section, which has multiple water passage holes 310. The multiple water passage holes 310 are evenly distributed in the circumferential direction of the first section.

[0028] In this embodiment, a hydraulic telescopic rod 330 is installed inside the water pumping pipe 300. When it is necessary to adjust the vertical extension and retraction position of the water pumping pipe 300 to monitor water quality at other depths, the extension and retraction of the hydraulic telescopic rod 330 drives the extension and retraction of multiple telescopic sections 340 on the water pumping pipe 300, thereby adjusting the vertical position of the water pumping pipe 300. Furthermore, when the water pumping pipe 300 retracts, some of the water inside the water pumping pipe 300 is forced out of the filter cartridge 320 in the reverse direction, providing a backwashing cleaning effect on the filter cartridge 320.

[0029] In a further embodiment, the turntable 200 includes at least one rotating fan 210, which includes two annular plates 211 and multiple fan blades 212. The two annular plates 211 are arranged vertically and coaxially on the float 100. The upper annular plate 211 is rotatably engaged with the float 100 via bearings, and a sealing plate 213 is provided on the lower annular plate 211 to seal it. Multiple fan blades 212 are evenly distributed around the central axis of the two annular plates 211, connecting them. The fan blades 212 are arc-shaped and inclined. Each pair of adjacent fan blades 212 arranged around the central axis of the annular plates 211 defines a flow channel, allowing water inside the rotating fan 210 to flow from the inside to the outside through the flow channel when the rotating fan 210 rotates.

[0030] In this embodiment, by setting up a rotating fan 210, after the entire detection device is immersed in water, water will enter the rotating fan 210 from the flow channel. The rotating fan 210, which is underwater, will rotate under the drive of the water flow. When the rotating fan 210 rotates, the water around the fan blade 212 will flow outward through the flow channel under the guidance of the arc-shaped fan blade 212.

[0031] In a further embodiment, four rotating fans 210 are provided. These four rotating fans 210 are referred to as the first fan 220, the second fan 230, the third fan 240, and the fourth fan 250. The first fan 220 is rotatably connected to the float 100 via bearings. The second fan 230 is located inside the first fan 220 and coaxially arranged with it, also rotatably connected to the first fan 220 via bearings. The third fan 240 is located at the lower end of the first fan 220 and coaxially arranged with it, and is fixedly connected to the second fan 230 via a first connecting plate 260. The fourth fan 250 is located inside the third fan 240 and coaxially arranged with it, and is located at the lower end of the second fan 230, fixedly connected to the first fan 220 via a second connecting plate 270. The diameter of the upper ring plate 211 of the first panel 220 is equal to the diameter of the upper ring plate 211 of the third panel 240, and the diameter of the upper ring plate 211 of the second panel 230 is equal to the diameter of the upper ring plate 211 of the fourth panel 250.

[0032] The tilt direction of the blades 212 of the first fan 220 is opposite to that of the blades 212 of the third fan 240, thus causing the direction in which the water flow drives the first fan 220 to rotate is opposite to the direction in which the water flow drives the third fan 240 to rotate. The tilt direction of the blades 212 of the first fan 220 is the same as that of the blades 212 of the second fan 230, thus causing the direction in which the water flows through the flow channel of the first fan 220 is opposite to the direction in which the water flows through the second fan 230. The tilt direction of the blades 212 of the third fan 240 is the same as that of the blades 212 of the fourth fan 250, thus causing the direction in which the water flows through the flow channel of the third fan 240 is opposite to the direction in which the water flows through the fourth fan 250.

[0033] In this design, the two ends of the fan blade 212 in the first fan 220 along the radial direction of the ring plate 211 are respectively referred to as the inner end and the outer end. The inner end is located inside the outer end, and the inner end and the outer end are arranged sequentially in the rotation direction of the first fan 220. Furthermore, in the rotation direction of the first fan 220, the outer end is located behind the inner end. That is, the first fan 220 is arranged according to... Figure 4 The direction shown is clockwise. The direction closer to the clockwise arrow is called the front, and the direction further away from the clockwise arrow is called the back.

[0034] This embodiment uses four rotating fans 210, see [link / reference] Figure 4 As shown, the first fan 220 in the diagram rotates clockwise under the drive of the water flow. (See also...) Figure 7 As shown, the rotation of the first fan 220 will drive the fourth fan 250 to rotate through the second connecting plate 270, and the rotation of the first fan 220 will cause the water around its fan blade 212 to flow outward through the flow channel under the guidance of the arc-shaped fan blade 212.

[0035] Since the tilt direction of the blade 212 of the first fan 220 is opposite to the tilt direction of the blade 212 of the third fan 240, the direction in which the water flow drives the first fan 220 to rotate is opposite to the direction in which the water flow drives the third fan 240 to rotate. The third fan 240 will rotate counterclockwise under the drive of the water flow, and the rotation of the third fan 240 will drive the second fan 230 to rotate through the first connecting plate 260.

[0036] That is, see Figure 4 As shown, the second fan 230 rotates counterclockwise, and this rotation causes the water around its upper fan blade 212 to flow inward through the flow channel under the guidance of the curved fan blade 212. Since the second fan 230 is located inside the first fan 220, and the diameter of the upper ring plate 211 of the second fan 230 is smaller than that of the upper ring plate 211 of the first fan 220, the amount of water discharged outward from the flow channel of the first fan 220 is greater than the amount of water drawn inward from the flow channel of the second fan 230. In other words, the flow channel of the second fan 230 can buffer and slow down the water about to flow out of the flow channel of the first fan 220, reducing the outward flow speed and preventing the water from flowing too fast and being discharged before the detection probe 400 has finished detecting the water.

[0037] For the third fan 240 and the fourth fan 250, since the tilt direction of the blades 212 of the third fan 240 is the same as that of the blades 212 of the fourth fan 250, but the third fan 240 rotates counterclockwise while the fourth fan 250 rotates clockwise under the influence of the first fan 220, their rotation directions are opposite. Therefore, the rotation of the third fan 240 will cause the water around its blades 212 to flow outward through the flow channel under the guidance of the curved blades 212. The rotation of the fourth fan 250 will cause the water around its blades 212 to flow inward through the flow channel under the guidance of the curved blades 212. Furthermore, since the fourth fan 250 is located inside the third fan 240, and the diameter of the upper ring plate 211 of the fourth fan 250 is smaller than that of the upper ring plate 211 of the third fan 240, when the water flows, the amount of water discharged outward from the flow channel of the third fan 240 is greater than the amount of water returned inward from the flow channel of the fourth fan 250. That is, the flow channel of the fourth fan 250 can buffer and slow down the water that is about to flow out of the flow channel of the third fan 240. Similar to the function of the second fan 230, the fourth fan 250 can also reduce the speed of the water flowing outward, thereby preventing the water from flowing too fast and being discharged before the detection probe 400 has finished detecting the water.

[0038] Furthermore, the first panel 220 and the fourth panel 250 are fixed together via the second connecting plate 270, and the second panel 230 and the third panel 240 are fixed together via the first connecting plate 260. The rotation direction of the first panel 220 is opposite to that of the third panel 240, which cancels out the rotational torque during rotation, preventing the first panel 220 from applying excessive torque to the float 100 and causing it to rotate. Alternatively, the float 100 can be locked with ropes. This prevents the float 100 from rotating and causing the detection probe 400 on it to revolve, thus preventing unstable detection.

[0039] Alternatively, when the flow rate of water from the inside to the outside in the rotating fan 210 is not considered, there is one rotating fan 210, which can be either the first fan 220 or the third fan 240. Or, there are two rotating fans 210, which can be the first fan 220 and the third fan 240 respectively.

[0040] In another possible embodiment, a cleaning block 410 is fitted onto the detection probe 400, and a transmission component is provided inside the rotating fan 210, which is used to drive the cleaning block 410 to move up and down on the detection probe 400.

[0041] The transmission components include a drive gear 420, a accumulator gear 430, and a release gear 440. The drive gear 420 is rotatably mounted on the detection probe 400. A drive rod 421 is mounted on the drive gear 420, and the drive rod 421 is arranged radially along the drive gear 420; this direction is referred to as the first direction. A drive block 423 is slidably mounted on the drive rod 421 via a first elastic element 422. The drive block 423 is connected to a cleaning block 410 via a connecting rod 424. Both ends of the connecting rod 424 are hinged to the drive block 423 and the cleaning block 410, respectively. The accumulator gear 430 is rotatably mounted on the float 100 via a first rotating shaft 431, which is arranged vertically. The release gear 440 is rotatably mounted on the first rotating shaft 431 and is connected to the accumulator gear 430 via a spring 441. The release gear 440 meshes with the drive gear 420. A receiving groove 432 is provided on the first rotating shaft 431. A stop 433 is connected to the receiving groove 432 via a second elastic element 434. The second elastic element 434 is arranged along a first direction and is a spring. A slot is provided on the release gear 440 for engaging with the stop 433. The second elastic element 434 always has a tendency to push the stop 433 towards the slot along the first direction. In the initial state, the stop 433 extends out of the receiving groove 432 and engages with the slot.

[0042] Specifically, a gear ring 231 is coaxially and fixedly mounted on the inner side of the ring plate 211 of the second fan 230. The energy storage gear 430 meshes with the gear ring 231. Thus, when the second fan 230 rotates, it can drive the gear ring 231 to rotate, and the gear ring 231 will drive the energy storage gear 430 to rotate.

[0043] Alternatively, in another possible embodiment, a gear ring 231 is coaxially and fixedly disposed on the inner side of the ring plate 211 of the second fan 230. The energy storage gear 430 meshes with the gear ring 231 through a reduction member, which reduces the speed of the energy storage gear 430, so that when the second fan 230 rotates, the second fan 230 can drive the gear ring 231 to rotate, and the gear ring 231 will drive the energy storage gear 430 to rotate through the reduction member.

[0044] Specifically, the reduction gear includes a first reduction gear 450, a second reduction gear 460, and a third reduction gear 470. The first reduction gear 450 is rotatably mounted on the pontoon 100 via a second rotating shaft 451 and meshes with a gear ring 231. The second reduction gear 460 is rotatably mounted on the pontoon 100 via a third rotating shaft 461 and meshes with the first reduction gear 450. The diameter of the first reduction gear 450 is larger than the diameter of the second reduction gear 460. The third reduction gear 470 is coaxially and fixedly connected to the second reduction gear 460, and the diameter of the second reduction gear 460 is larger than the diameter of the third reduction gear 470. The third reduction gear 470 meshes with a power storage gear 430, and the diameter of the third reduction gear 470 is smaller than the diameter of the power storage gear 430, while the diameter of the first reduction gear 450 is larger than the diameter of the power storage gear 430.

[0045] The drive gear 420, the storage gear 430, the release gear 440, the first reduction gear 450, the second reduction gear 460, and the third reduction gear 470 all have an anti-rust coating, or they can be made of high-strength plastic.

[0046] Furthermore, multiple transmission components and reduction components are provided, with each transmission component, reduction component, and detection probe 400 corresponding to one another.

[0047] In this embodiment, by setting up a cleaning block 410 and a transmission component, when the gear ring 231 is driven to rotate by the second fan 230, the gear ring 231 will drive the energy storage gear 430 to rotate through the reduction component. The energy storage gear 430 will drive the spring 441 to rotate and store energy. When the energy stored in the spring 441 can overcome the elastic force of the second elastic element 434 connected to the stop block 433, the stop block 433 will be pressed into the receiving groove 432. Then, the release gear 440 will rotate rapidly, and the spring 441 will be released. The rotation of the release gear 440 will drive the drive gear 420 to rotate. The rotation of the drive gear 420 will cause the drive block 423 to slide away from the detection probe 400 under the action of centrifugal force, and compress the first elastic element 422. The sliding of the drive block 423 will drive the cleaning block 410 to move upward through the connecting rod 424, and the cleaning block 410 will clean the detection probe 400. After the spring 441 is released, the release gear 440 will stop rotating. At this time, the second elastic element 434 causes the stop block 433 to reset and engage with the slot again. The first elastic element 422 causes the drive block 423 to reset. The drive block 423 drives the cleaning block 410 to reset through the drive rod 421.

[0048] In a further embodiment, the pontoon 100 has a cavity 110, within which a generator 120 and a power supply are installed. A second rotating shaft 451 is fixedly mounted on the output end of the generator 120, so that the generator 120 can generate electricity when the second rotating shaft 451 rotates. The power supply is electrically connected to the generator 120. The power supply is used to power the detection probe 400, enabling the detection probe 400 to perform detection.

[0049] Furthermore, a solar panel 130 is installed on the upper part of the pontoon 100, and the solar panel 130 is electrically connected to the power supply. The solar panel 130 can also power the detection probe 400.

[0050] In this embodiment, the rotation of the second fan 230 stores energy for the generator 120, enabling it to work in conjunction with the solar panel 130 to power the detection probe 400, ensuring the normal operation of the detection.

[0051] Based on the above embodiments, the specific working process is as follows: When testing the water quality of the reservoir, the floating tower 100 is deployed to the reservoir monitoring area. The floating tower 100 floats vertically on the water surface, and its lower turntable 200, detection probe 400 and water pumping pipe 300 are all submerged underwater. The vertical extension length of the water pumping pipe 300 is adjusted according to the monitoring requirements so that the filter cylinder 320 at the lower end of the water pumping pipe 300 is at the target detection depth.

[0052] See Figure 4 As shown, the first fan 220 in the diagram rotates clockwise under the drive of the water flow. (See also...) Figure 7 As shown, the rotation of the first fan 220 will drive the fourth fan 250 to rotate through the second connecting plate 270, and the rotation of the first fan 220 will cause the water around its fan blade 212 to flow outward through the flow channel under the guidance of the arc-shaped fan blade 212.

[0053] Since the tilt direction of the blade 212 of the first fan 220 is opposite to the tilt direction of the blade 212 of the third fan 240, the direction in which the water flow drives the first fan 220 to rotate is opposite to the direction in which the water flow drives the third fan 240 to rotate. The third fan 240 will rotate counterclockwise under the drive of the water flow, and the rotation of the third fan 240 will drive the second fan 230 to rotate through the first connecting plate 260.

[0054] That is, see Figure 4 As shown, the second fan 230 rotates counterclockwise, and this rotation causes the water around its upper fan blade 212 to flow inward through the flow channel under the guidance of the curved fan blade 212. Since the second fan 230 is located inside the first fan 220, and the diameter of the upper ring plate 211 of the second fan 230 is smaller than that of the upper ring plate 211 of the first fan 220, the amount of water discharged outward from the flow channel of the first fan 220 is greater than the amount of water drawn inward from the flow channel of the second fan 230. In other words, the flow channel of the second fan 230 can buffer and slow down the water about to flow out of the flow channel of the first fan 220, reducing the outward flow speed and preventing the water from flowing too fast and being discharged before the detection probe 400 has finished detecting the water. Similar to the function of the second gate 230, the flow channel of the fourth gate 250 can buffer and slow down the water that is about to flow out of the flow channel of the third gate 240. The fourth gate 250 can also reduce the speed of the water flowing outward, thereby preventing the water from flowing too fast and being discharged before the detection probe 400 has finished detecting the water.

[0055] During water discharge, the pump pipe 300 delivers water at its designated depth through the water hole 310 into the turntable 200. This allows the detection probe 400 to detect the water at the depth corresponding to the lower end of the pump pipe 300. The water entering the pump pipe 300 is first filtered by the filter cartridge 320 to prevent impurities from entering the turntable 200. This creates a relatively sealed position for the detection probe 400 within the turntable 200, providing protection and reducing the adverse effects of impurities, thus improving detection accuracy. Once the water at the depth corresponding to the lower end of the pump pipe 300 enters the turntable 200, multiple different detection probes 400 can be used to detect water quality parameters (such as water temperature, pH value, dissolved oxygen, etc.) within the turntable 200.

[0056] When it is necessary to adjust the vertical extension / retraction position of the pumping pipe 300 to monitor water quality at other depths, the extension / retraction of the hydraulic telescopic rod 330 drives the extension / retraction of multiple telescopic sections 340 on the pumping pipe 300, thereby adjusting the vertical position of the pumping pipe 300. Furthermore, when the pumping pipe 300 retracts, some water inside the pumping pipe 300 is forced out of the filter cartridge 320 in the reverse direction, providing a backwashing effect on the filter cartridge 320.

[0057] This invention also provides an online monitoring method for reservoir water quality, utilizing the aforementioned online reservoir water quality monitoring device, comprising the following steps: S10, the detection device is deployed to the preset monitoring area of ​​the reservoir, so that the floating tower 100 floats on the water surface in the vertical direction, and the turntable 200, detection probe 400 and water pumping pipe 300 are all submerged in the water; S20 drives the turntable 200 to rotate around its own vertical axis, causing the water inside the turntable 200 to be discharged from the inside to the outside; S30, water is pumped through water pipe 300 and water hole 310 into turntable 200; S40 uses the detection probe 400 to detect water quality parameters (such as water temperature, pH value, dissolved oxygen, turbidity, etc.) of the water in the turntable 200.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
