[0002] Water quality analysis of a reservoir is an important means to evaluate and detect the water quality condition of the reservoir, which is of great significance to the sustainable use of water resources, the maintenance of ecological environment balance and the safety of drinking water for the public. Through detection and evaluation of the water quality of the reservoir, the public's awareness and participation in water resource protection can be improved.

The floating body carries multiple water quality sensors to realize real-time monitoring of key parameters in the water body.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0032] An embodiment of the reservoir water quality on-line detection device of the present application is shown in Figures 1 to 9

[0033] ​The online detection device for reservoir water quality comprises a floating tower 100, a rotating disc 200, a water pumping pipe 300 and at least one detection probe 400. The floating tower 100 is arranged along the vertical direction and can float on the water surface. The rotating disc 200 is a cylindrical structure arranged along the vertical direction and its lower end is blocked. The rotating disc 200 is rotatably installed at the lower end of the floating tower 100 and located underwater, and when the rotating disc 200 rotates around its own axis, the water in the rotating disc 200 can flow from the inside to the outside along the radial direction of the rotating disc 200. The side close to the central axis of the rotating disc 200 along the radial direction is called the inside, and the side away from the central axis is called the outside. The detection probe 400 is fixedly installed at the lower end of the floating tower 100 and located in the rotating disc 200. The water pumping pipe 300 is arranged along the vertical direction and installed at the lower end of the floating tower 100. The water pumping pipe 300 penetrates the rotating disc 200 along the vertical direction and can be telescoped in the vertical direction. The water pumping pipe 300 is provided with a water passing hole 310 located in the rotating disc 200. The lower end of the water pumping pipe 300 is provided with a filter cylinder 320 which is in communication with the water pumping pipe 300.

[0034] Further, the water passing hole 310 is arranged close to the detection probe 400 along the vertical direction, so that the water entering the rotating disc 200 through the water passing hole 310 can directly reach the position of the detection probe 400, facilitating the detection of the water depth at this position.

[0035] The floating tower 100 is provided with an ear plate 101, and a rope is connected to the ear plate 101. By making the floating tower 100 have a large surface area and a light weight, the floating tower 100 provides a large buoyancy to make the entire detection device float on the sea surface. The rope is used to lock the floating tower 100 with solid objects such as stones in the water to prevent the entire detection device from drifting in the water.

[0036] In this embodiment, the floating tower 100, the rotating disc 200, the detection probe 400 and the water pumping pipe 300 are cooperated to detect the reservoir water quality. When detecting the reservoir water quality, the floating tower 100 is put into the monitoring area of the reservoir. The floating tower 100 floats along the vertical direction on the water surface, and the rotating disc 200, the detection probe 400 and the water pumping pipe 300 at the lower end of the floating tower 100 are all submerged underwater. The telescoping length of the water pumping pipe 300 in the vertical direction is adjusted according to the monitoring requirement, so that the filter cylinder 320 at the lower end of the water pumping pipe 300 is located at the target detection depth.

[0037] Then the rotating disc 200 is driven to rotate, and the rotation of the rotating disc 200 will continuously discharge water in the rotating disc 200 outward, in the process of discharging water, the water pump 300 can send the water at the depth corresponding to the lower end of the water pump 300 into the rotating disc 200 through the water hole 310, so that the detection probe 400 detects the water at the depth corresponding to the lower end of the water pump 300, and the water entering the water pump 300 will be filtered by the filter cylinder 320 first, so as to avoid that the water entering the rotating disc 200 has impurities, and thus the position of the detection probe 400 in the rotating disc 200 is relatively sealed, which can protect the detection probe 400 to a certain extent, reduce the adverse effects of impurities on the detection probe 400, and improve the detection accuracy. When the water at the depth corresponding to the lower end of the water pump 300 enters the rotating disc 200, a plurality of different detection probes 400 can be arranged to detect the water quality parameters (such as water temperature, pH value, dissolved oxygen, turbidity, etc.) of the water in the rotating disc 200. If it is necessary to monitor the water quality at other depths, it is only necessary to adjust the vertical telescopic position of the water pump 300, so that the filter cylinder 320 moves to a new target depth, and the detection process of discharging water, filtering, pumping water and sending water is repeated, so that continuous detection of water quality at different depths can be realized, and the detection range is expanded.

[0038] In a further embodiment, the water pump 300 is a telescopic pipe, and a hydraulic telescopic rod 330 is arranged inside the water pump 300. The hydraulic telescopic rod 330 is arranged in the vertical direction and can be telescoped in the vertical direction. The upper and lower ends of the hydraulic telescopic rod 330 are connected with the floating tower 100 and the water pump 300 respectively. A driving member is arranged on the floating tower 100, and the driving member is used to drive the hydraulic telescopic rod 330 to telescope in the vertical direction. The driving member is a prior art, and a hydraulic cylinder can be used for driving.

[0039] The water pump 300 includes a plurality of telescopic segments 340, which are arranged in the vertical direction in sequence, and two telescopic segments 340 arranged in the vertical direction are slidingly matched. The telescopic segment 340 close to the detection probe 400 in the vertical direction is referred to as a first segment, and the water hole 310 is provided with a plurality of water holes. The plurality of water holes 310 are uniformly distributed in the circumferential direction of the first segment.

[0040] In this embodiment, the hydraulic telescopic rod 330 is arranged inside the water pump 300. When it is necessary to adjust the vertical telescopic position of the water pump 300 to monitor the water quality at other depths, the telescopic segments 340 on the water pump 300 are driven to telescope by the telescoping of the hydraulic telescopic rod 330, so that the position of the water pump 300 in the vertical direction can be adjusted. When the water pump 300 is contracted, part of the water in the water pump 300 will be squeezed out from the filter cylinder 320 in the opposite direction, so as to play a backwashing effect on the filter cylinder 320.

[0041] In a further embodiment, the rotating disc 200 comprises at least one rotating fan 210, which comprises two ring plates 211 and a plurality of fan blades 212. The two ring plates 211 are arranged in sequence and coaxially in the vertical direction on the floating tower 100, the ring plate 211 at the upper side is rotationally connected with the floating tower 100 through a bearing, and the ring plate 211 at the lower side is provided with a blocking plate 213 for blocking the ring plate 211 at the lower side. The plurality of fan blades 212 are arranged uniformly around the central axis of the ring plate 211 and connect the two ring plates 211. The fan blades 212 are arranged in an arc shape and are inclined, and each two adjacent fan blades 212 around the central axis of the ring plate 211 define a flow channel, and when the rotating fan 210 rotates, the water inside the rotating fan 210 can flow from the inside to the outside through the flow channel.

[0042] In the embodiment, the rotating fan 210 is arranged, after the entire detection device is put into water, water will enter the rotating fan 210 from the flow channel, and the rotating fan 210 under water will rotate under the driving of the water flow, and when the rotating fan 210 rotates, the water around the fan blades 212 will flow outward through the flow channel under the guiding action of the arc-shaped fan blades 212.

[0043] In a further embodiment, the rotating fan 210 is provided with four. The four rotating fans 210 are respectively referred to as a first fan 220, a second fan 230, a third fan 240 and a fourth fan 250. The first fan 220 is rotationally connected with the floating tower 100 through a bearing, the second fan 230 is arranged inside the first fan 220 and coaxially with the first fan 220, and the second fan 230 is rotationally connected with the first fan 220 through a bearing. The third fan 240 is arranged at the lower end of the first fan 220 and coaxially with the first fan 220, the third fan 240 is fixedly connected with the second fan 230 through a first connecting plate 260, the fourth fan 250 is arranged inside the third fan 240 and coaxially with the third fan 240, the fourth fan 250 is arranged at the lower end of the second fan 230, and the fourth fan 250 is fixedly connected with the first fan 220 through a second connecting plate 270. The diameter of the ring plate 211 on the first fan 220 is equal to the diameter of the ring plate 211 on the third fan 240, and the diameter of the ring plate 211 on the second fan 230 is equal to the diameter of the ring plate 211 on the fourth fan 250.

[0044] The tilting direction of the fan blades 212 of the first fan 220 is opposite to that of the fan blades 212 of the third fan 240, and thus the direction in which the water flow drives the first fan 220 to rotate is opposite to that in which the water flow drives the third fan 240 to rotate. The tilting direction of the fan blades 212 of the first fan 220 is the same as that of the fan blades 212 of the second fan 230, and thus the direction in which the water flow flows through the flow channel of the first fan 220 is opposite to that in which the water flow flows through the second fan 230. The tilting direction of the fan blades 212 of the third fan 240 is the same as that of the fan blades 212 of the fourth fan 250, and thus the direction in which the water flow flows through the flow channel of the third fan 240 is opposite to that in which the water flow flows through the fourth fan 250.

[0045] In the first fan 220, the two ends of the fan blades 212 in the radial direction of the ring plate 211 are respectively referred to as an inner end and an outer end, the inner end is located inward of the outer end, the inner end and the outer end are sequentially arranged in the rotation direction of the first fan 220, and in the rotation direction of the first fan 220, the outer end is located at the rear side of the inner end. That is, the first fan 220 rotates clockwise in the direction shown in FIG. 8, and the direction on the side close to the arrow of clockwise rotation in the rotation direction is referred to as front, and the direction on the side away from the arrow of clockwise rotation in the rotation direction is referred to as rear. Figure 4 In the first fan 220, the two ends of the fan blades 212 in the radial direction of the ring plate 211 are respectively referred to as an inner end and an outer end, the inner end is located inward of the outer end, the inner end and the outer end are sequentially arranged in the rotation direction of the first fan 220, and in the rotation direction of the first fan 220, the outer end is located at the rear side of the inner end. That is, the first fan 220 rotates clockwise in the direction shown in FIG. 8, and the direction on the side close to the arrow of clockwise rotation in the rotation direction is referred to as front, and the direction on the side away from the arrow of clockwise rotation in the rotation direction is referred to as rear.

[0046] The present embodiment is provided with four rotating fans 210, as shown in FIG. 1, in which the first fan 220 rotates clockwise under the drive of the water flow. As shown in FIG. 2, the rotation of the first fan 220 drives the fourth fan 250 to rotate through the second connecting plate 270, and the rotation of the first fan 220 causes the water around the fan blades 212 thereon to flow outward through the flow channel under the guidance of the arc-shaped fan blades 212. Figure 4 Figure 7 As shown in FIG. 3, the rotation of the fourth fan 250 drives the second fan 230 to rotate through the first connecting plate 260.

[0047] As the tilting direction of the fan blades 212 of the first fan 220 is opposite to that of the fan blades 212 of the third fan 240, the direction in which the water flow drives the first fan 220 to rotate is opposite to that in which the water flow drives the third fan 240 to rotate, and the third fan 240 rotates counterclockwise under the drive of the water flow, and the rotation of the third fan 240 drives the second fan 230 to rotate through the first connecting plate 260.

[0048] That is, as shown in FIG. 4, the water flow flows through the flow channel of the first fan 220, and the water flow flows through the flow channel of the second fan 230. Figure 4 ​As shown, the second fan 230 rotates counterclockwise, and the rotation of the second fan 230 causes the water around the blades 212 on the second fan 230 to flow inward through the flow channels under the guidance of the arc-shaped blades 212. Since the second fan 230 is inside the first fan 220, the diameter of the ring plate 211 on the second fan 230 is smaller than that of the ring plate 211 on the first fan 220, and thus the amount of water flowing outward from the flow channels of the first fan 220 is greater than the amount of water flowing inward from the flow channels of the second fan 230. That is, the flow channels of the second fan 230 can slow down the water flowing outward and prevent the water from flowing too fast, so that the detection probe 400 can detect the water completely before the water is discharged.

[0049] As for the third fan 240 and the fourth fan 250, since the blades 212 of the third fan 240 are inclined in the same direction as the blades 212 of the fourth fan 250, but the third fan 240 rotates counterclockwise and the fourth fan 250 rotates clockwise under the drive of the first fan 220, the rotation directions of the third fan 240 and the fourth fan 250 are opposite, and thus the rotation of the third fan 240 causes the water around the blades 212 on the third fan 240 to flow outward through the flow channels under the guidance of the arc-shaped blades 212. The rotation of the fourth fan 250 causes the water around the blades 212 on the fourth fan 250 to flow inward through the flow channels under the guidance of the arc-shaped blades 212. Since the fourth fan 250 is inside the third fan 240, the diameter of the ring plate 211 on the fourth fan 250 is smaller than that of the ring plate 211 on the third fan 240, and thus the amount of water flowing outward from the flow channels of the third fan 240 is greater than the amount of water flowing inward from the flow channels of the fourth fan 250. That is, the flow channels of the fourth fan 250 can slow down the water flowing outward and prevent the water from flowing too fast, so that the detection probe 400 can detect the water completely before the water is discharged.

[0050] The first fan 220 and the fourth fan 250 are fixed together by the second connecting plate 270, the second fan 230 and the third fan 240 are fixed together by the first connecting plate 260, and the rotation direction of the first fan 220 is opposite to that of the third fan 240, so that the rotation torques of the first fan 220 and the third fan 240 can cancel each other when the first fan 220 and the third fan 240 rotate, and thus the first fan 220 does not apply too large a rotation torque to the floating tower 100 to cause the floating tower 100 to rotate. Of course, the floating tower 100 can also be locked by a rope, and this arrangement can prevent the floating tower 100 from rotating and driving the detection probe 400 to revolve, so that the detection is stable.

[0051] Or, when not considering the water flow rate from inside to outside in the rotating fan 210, the rotating fan 210 is provided with one, and the rotating fan 210 is the first fan 220 or the third fan 240. Or, the rotating fan 210 is provided with two, and the two rotating fans 210 are the first fan 220 and the third fan 240 respectively.

[0052] In other possible embodiments, a cleaning block 410 is sleeved on the detection probe 400, and a transmission member is arranged in the rotating fan 210, and the transmission member is used to drive the cleaning block 410 to move up and down on the detection probe 400.

[0053] The transmission member includes a driving gear 420, a force storage gear 430, and a release gear 440. The driving gear 420 is rotatably installed on the detection probe 400, and a driving rod 421 is arranged on the driving gear 420 in a radial direction of the driving gear 420, and the direction of the driving rod 421 is referred to as a first direction. A driving block 423 is slidably arranged on the driving rod 421 by a first elastic member 422, and the driving block 423 is connected to the cleaning block 410 by a connecting rod 424. The two ends of the connecting rod 424 are hingedly connected to the driving block 423 and the cleaning block 410 respectively. The force storage gear 430 is rotatably installed on a first rotating shaft 431 by the first rotating shaft 431 arranged in a vertical direction. The release gear 440 is rotatably installed on the first rotating shaft 431, and the release gear 440 is connected to the force storage gear 430 by a clockwork spring 441. The release gear 440 is engaged with the driving gear 420.

Further, 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 force storage gear 430 to rotate.

[0055] Or, in other possible embodiments, the inner side of the ring plate 211 of the second fan 230 is coaxially and fixedly provided with a gear ring 231.

[0061] Further, the floating tower 100 is provided with a solar panel 130 at an upper end thereof, and the solar panel 130 is electrically connected with the power supply. The solar panel 130 can also supply power to the detection probe 400.

[0062] In this embodiment, the second fan 230 is rotated to store energy for the power generator 120, so that the power generator 120 can supply power to the detection probe 400 in cooperation with the solar panel 130, and ensure normal detection.

[0063] In combination with the above embodiment, the specific working process is as follows:

[0064] When detecting the water quality of the reservoir, the floating tower 100 is put into the monitoring area of the reservoir, and the floating tower 100 floats in the vertical direction on the water surface. The rotating disc 200, the detection probe 400 and the water suction pipe 300 at the lower end of the floating tower 100 are all submerged in water, and the extension length of the water suction pipe 300 in the vertical direction is adjusted according to the monitoring requirement, so that the filter cylinder 320 at the lower end of the water suction pipe 300 is at the target detection depth.

[0065] Referring to FIG. 1, Figure 4 Referring to FIG. 2, the first fan 220 rotates clockwise under the driving of the water flow. Referring to FIG. 3, Figure 7 The rotation of the first fan 220 drives the fourth fan 250 to rotate through the second connecting plate 270, and the rotation of the first fan 220 drives the water around the blades 212 of the first fan 220 to flow outward through the flow channel under the guidance of the arc-shaped blades 212.

[0066] Since the inclination direction of the blades 212 of the first fan 220 is opposite to the inclination direction of the blades 212 of the third fan 240, the direction in which the first fan 220 is driven to rotate by the water flow is opposite to the direction in which the third fan 240 is driven to rotate by the water flow. The third fan 240 rotates counterclockwise under the driving of the water flow, and the rotation of the third fan 240 drives the second fan 230 to rotate through the first connecting plate 260.

[0067] That is, referring to FIG. 4, Figure 4As shown, the second fan 230 rotates counterclockwise, and the rotation of the second fan 230 causes the water around the fan blades 212 on the second fan 230 to flow inward along the flow channel under the guidance of the arc-shaped fan blades 212. Since the second fan 230 is located inside the first fan 220, the diameter of the ring plate 211 on the second fan 230 is smaller than that of the ring plate 211 on the first fan 220, and thus the amount of water flowing outward from the flow channel of the first fan 220 is greater than the amount of water flowing inward from the flow channel of the second fan 230. That is, the flow channel of the second fan 230 can buffer and slow down the water flowing out of the flow channel of the first fan 220, thereby reducing the speed of the water flowing outward and preventing the water from flowing too fast and being discharged before the detection probe 400 has finished detecting the water. Similarly, the flow channel of the fourth fan 250 can buffer and slow down the water flowing out of the flow channel of the third fan 240, and the fourth fan 250 can also reduce the speed of the water flowing outward and prevent the water from flowing too fast and being discharged before the detection probe 400 has finished detecting the water.

[0068] During the water discharge process, the water pump 300 can send the water at the depth where the water pump 300 is located to the rotating disc 200 through the water hole 310, so that the detection probe 400 detects the water at the depth corresponding to the lower end of the water pump 300. The water entering the water pump 300 is filtered by the filter cylinder 320 first, so as to avoid the water entering the rotating disc 200 from containing impurities, thereby relatively sealing the position of the detection probe 400 in the rotating disc 200, protecting the detection probe 400 to a certain extent, reducing the adverse effects of impurities on the detection probe 400, and improving the detection accuracy. When the water at the depth corresponding to the lower end of the water pump 300 enters the rotating disc 200, a plurality of different detection probes 400 can be arranged to detect the water quality parameters (such as water temperature, pH value, dissolved oxygen, etc.) of the water in the rotating disc 200.

[0069] When it is necessary to adjust the vertical telescopic position of the water pump 300 and monitor the water quality at other depths, the plurality of telescopic sections 340 on the water pump 300 can be driven to telescope by the telescopic hydraulic rod 330, so as to adjust the position of the water pump 300 in the vertical direction. When the water pump 300 is contracted, part of the water in the water pump 300 will be squeezed out from the filter cylinder 320 in the opposite direction, thereby cleaning the filter cylinder 320 by backwashing.

[0070] The application also provides an online monitoring method for water quality in a reservoir, which utilizes the above-mentioned online detection device for water quality in a reservoir and comprises the following steps:

[0071] S10, the detection device is put into a preset monitoring area of the reservoir, so that the floating tower 100 floats on the water surface along the vertical direction, and the rotating disc 200, the detection probe 400 and the water pump 300 are all submerged in water.

[0072] S20, drive the rotating disc 200 to rotate around its vertical axis, so that the water in the rotating disc 200 is discharged from inside to outside;

[0073] S30, send the water to the rotating disc 200 through the water hole 310 by the water pump 300;

[0074] S40, detect the water quality parameters (such as water temperature, pH value, dissolved oxygen, turbidity, etc.) of the water body in the rotating disc 200 by the detection probe 400.

[0075] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
