Technical Field

[0001] This invention relates to the field of river water environment monitoring technology, specifically to a river water environment monitoring device and its monitoring method. Background Technology

Installed in the river, it allows for real-time monitoring of water quality. The use of this monitoring device provides timely and accurate water environment data, helping to protect the river's ecological environment and manage water resources.

[0008] Preferably, a floating airbag is fixedly connected to the bottom of the floating disc, and the interior of the floating disc is hollow.

[0009] Preferably, the detection body includes a pH sensor, a dissolved oxygen sensor, a first rotating arm, a fixed frame, an electric push rod, a turbidity sensor, a conductivity sensor, a second rotating arm, an arc-shaped toothed disc, a temperature sensor, an ammonia nitrogen sensor, a third rotating arm, and a drive control gear. Three arc-shaped toothed discs are provided, evenly distributed on the outer side of the drive control gear, and all three are meshed with the drive control gear. The first, second, and third rotating arms are fixedly connected to the three arc-shaped toothed discs. Six fixed frames and six electric push rods are provided, evenly and symmetrically arranged on the first, second, and third rotating arms, with the electric push rods fixedly mounted on the fixed frames. The pH sensor and the dissolved oxygen sensor are fixedly connected to the bottom ends of two electric push rods on the first rotating arm. The turbidity sensor and the conductivity sensor are fixedly connected to the bottom ends of two electric push rods on the second rotating arm. The temperature sensor and the ammonia nitrogen sensor are fixedly connected to the bottom ends of two electric push rods on the third rotating arm.

[0010] Preferably, the drive control gear is rotatably mounted in the middle of the mounting and protective frame, the drive end of the motor is fixedly connected to the upper middle of the drive control gear, the arc-shaped gear disk is rotatably mounted on the mounting and protective frame, and the sliding mounting plate is slidably engaged with the sliding limit plate.

[0011] Preferably, the power generation protection unit includes a fixed support frame, a sealing plate, a protective mounting frame, a photovoltaic panel, a controller, and a wireless module. The sealing plate is securely mounted on the upper end of the protective mounting frame, the photovoltaic panel is uniformly fixed on the protective mounting frame, the fixed support frame is fixedly mounted on the upper end of the sealing plate by bolts, and the controller and the wireless module are fixedly mounted on the bottom end of the sealing plate.

[0012] Preferably, the pH sensor, dissolved oxygen sensor, turbidity sensor, conductivity sensor, temperature sensor, and ammonia nitrogen sensor are all wirelessly connected to the controller.

[0013] Preferably, a conical protective cover is fixedly installed on the upper end of the fixed support frame, and the material of the conical protective cover is transparent plastic.

[0014] A monitoring method for a river water environment monitoring device includes the following steps:

[0015] S1. First, the upper end of the fixing pin is pressed by external force, so that the bottom of the fixing pin is inserted into the designated river water flow. The first interceptor and the second interceptor can be folded and rotated to adjust the installation interception range of the first interceptor and the second interceptor. When the bottom end of each fixing pin is inserted into the river, the first interceptor and the second interceptor can be fixedly installed at the designated river detection position. After the first interceptor and the second interceptor are fixedly installed at the designated position, the sliding mounting plate in the first detection device and the second detection device can be slidably locked onto the sliding limit plate to be installed at the end of the first interceptor and the second interceptor. The first detection device and the second detection device can float on the water surface being detected. The first detection device and the second detection device can be easily removed from the first interceptor and the second interceptor by sliding the sliding mounting plate off the sliding limit plate.

[0016] S2. During use, the first and second interceptor frames can intercept larger impurities floating in the water flow, allowing the impurities floating in the river to be intercepted and cleaned. The motors in the first and second detection devices are periodically activated, which drive the drive control gear to rotate. The rotating drive control gear drives the three arc-shaped gear discs to rotate synchronously. The rotating arc-shaped gear discs synchronously drive the first, second, and third rotating arms to rotate from inside the protective frame and be discharged from the mounting slot of the protective frame. This allows the various fixed frames, electric push rods, and sensors such as pH, dissolved oxygen, turbidity, conductivity, temperature, and ammonia nitrogen to be discharged from inside the protective frame and the outer protective frame and move to the water surface.

[0017] S3. During testing, the controller can operate the corresponding electric push rods according to the parameters to be detected. This causes one or more of the pH, dissolved oxygen, turbidity, conductivity, temperature, and ammonia nitrogen sensors to move downwards into the water flow to detect the water flow. The various parameters detected by the pH, dissolved oxygen, turbidity, conductivity, temperature, and ammonia nitrogen sensors are transmitted to the controller, and the detection information is wirelessly transmitted to the tester via the wireless module. After the pH, dissolved oxygen, turbidity, conductivity, temperature, and ammonia nitrogen sensors have completed their detection, the motor is started to drive the drive control gear to rotate, causing the first, second, and third rotating arms to return to the installation and protective frame. During use, the photovoltaic panel can generate electricity to power the operation of this equipment. The controller and wireless module are protected by the sealing plate and the protective installation frame. A conical protective cover is installed at the upper end of the fixed support frame to prevent rain. The conical protective cover is made of transparent plastic and does not affect the operation of the photovoltaic panel.

[0018] The beneficial effects of this invention are:

[0019] I. The first and second detection devices of this invention can float stably on the water surface. During use, one or more of the pH sensor, dissolved oxygen sensor, turbidity sensor, conductivity sensor, temperature sensor, and ammonia nitrogen sensor can be rotated out from the protective frame and outer protective frame for detection. After use, they can automatically rotate back into the protective frame and installation protective frame for protection. The pH sensor measures the acidity or alkalinity of the water, the dissolved oxygen sensor measures the dissolved oxygen content in the water. Dissolved oxygen is a measure of the oxygen content in the water and plays an important role in the survival of aquatic organisms and water quality assessment. The turbidity sensor measures the concentration of suspended particulate matter in the water, reflecting the transparency of the water. The conductivity sensor measures the conductivity of the water, i.e., the water's ability to conduct electricity. Conductivity is an important indicator for measuring the ion content and the ability to dissolve substances in water. The temperature sensor measures the temperature of the water. Water temperature has a direct impact on the aquatic ecosystem and aquatic chemical processes. The ammonia nitrogen sensor measures the ammonia nitrogen content in the water to assess and monitor the degree of water pollution. Therefore, this device can conveniently and accurately detect various parameters of river flow in real time and periodically.

[0020] II. The first and second interceptor frames of this invention can be folded and rotated to adjust their installation and interception range. During use, the first and second interceptor frames can intercept larger floating impurities in the water flow, allowing the impurities floating in the river to be intercepted and cleaned. When the bottom ends of each fixing pin are inserted into the river's interior, the first and second interceptor frames can be fixedly installed at the designated river detection position. After the first and second interceptor frames are fixedly installed at the designated position, the sliding mounting plates in the first and second detection devices can be slidably engaged with the sliding limit plate to achieve the desired effect. The first and second detection devices are slidably snapped onto the ends of the first and second interceptor frames, and can float on the water surface being tested. By sliding the mounting plate off the sliding limit plate, the first and second detection devices can be easily removed from the first and second interceptor frames, making it easy to fix them on the first and second interceptor frames for use and removal. The fixation by the first and second interceptor frames also ensures the stability of the first and second detection devices during use. Attached Figure Description

[0036] The invention will be further described below with reference to the accompanying drawings.

[0037] Example 1

The first detection device 1 and the second detection device 3 are snapped together at both ends of the fixed interception device 2, and the first detection device 1 and the second detection device 3 have the same structure. The fixed interception device 2 includes a baffle plate 4, a sliding limit plate 5, a fixing pin 6, a first interception frame 7, a second interception frame 8, and a limiting frame 9. The first interception frame 7 and the second interception frame 8 are rotatably connected by a rotating shaft. The sliding limit plate 5 is fixedly connected to the outer ends of the first interception frame 7 and the second interception frame 8. The baffle plate 4 is symmetrically fixedly connected to the bottom end of the sliding limit plate 5. The limiting frame 9 is uniformly and symmetrically fixedly installed at the ends of the first interception frame 7 and the second interception frame 8. The fixing pin 6 is slidably snapped into the inside of the limiting frame 9. The first detection device 1 and the second detection device 3 both include a power generation protection part 11 and a floating detection part 12. The power generation protection part 11 is located at the upper end of the floating detection part 12.

[0039] like Figure 6 As shown, the floating detection unit 12 includes a motor 13, a protective outer frame 14, a mounting protective frame 15, a floating disk 16, a sliding mounting plate 18, and a detection body 19. The mounting protective frame 15 is fixedly connected to the upper middle part of the floating disk 16, and the detection body 19 is disposed inside the mounting protective frame 15. The motor 13 is fixedly connected to the upper middle part of the mounting protective frame 15, the protective outer frame 14 is evenly fixedly connected to the mounting protective frame 15, and the sliding mounting plate 18 is fixedly connected to the side end of the mounting protective frame 15. The protective outer frame 14 and the mounting protective frame 15 play a protective and safeguarding role.

[0040] like Figure 7 As shown, a floating airbag 17 is fixedly connected to the bottom of the floating plate 16. The interior of the floating plate 16 is hollow, which allows the device to float stably on the water surface.

[0041] like Figure 8As shown, the detection body 19 includes a pH sensor 20, a dissolved oxygen sensor 21, a first rotating arm 22, a fixed frame 23, an electric push rod 24, a turbidity sensor 25, a conductivity sensor 26, a second rotating arm 27, an arc-shaped toothed disk 28, a temperature sensor 29, an ammonia nitrogen sensor 30, a third rotating arm 31, and a drive control gear 32. Three arc-shaped toothed disks 28 are provided, evenly distributed on the outside of the drive control gear 32, and all three are meshed with the drive control gear 32. The first rotating arm 22, the second rotating arm 27, and the third rotating arm 31 are respectively fixedly connected to the three arc-shaped toothed disks 28. Six fixed frames 23 and six electric push rods 24 are provided. Rods 24 are evenly and symmetrically arranged on the first rotating arm 22, the second rotating arm 27, and the third rotating arm 31, respectively. The electric push rods 24 are fixedly mounted on the fixed frame 23. A pH sensor 20 and a dissolved oxygen sensor 21 are fixedly connected to the bottom ends of the two electric push rods 24 on the first rotating arm 22. A turbidity sensor 25 and a conductivity sensor 26 are fixedly connected to the bottom ends of the two electric push rods 24 on the second rotating arm 27. A temperature sensor 29 and an ammonia nitrogen sensor 30 are fixedly connected to the bottom ends of the two electric push rods 24 on the third rotating arm 31. The rotating drive control gear 32 can drive the three arc-shaped gear discs 28 to rotate synchronously. The rotating arc-shaped gear discs 28 can then synchronously drive the first rotating arm 22 and the second rotating arm 31 to rotate synchronously. Arm 27 and the third rotating arm 31 rotate from inside the mounting protective frame 15 and are discharged from the mounting slot of the mounting protective frame 15. This allows each fixed bracket 23, electric push rod 24, and pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 to be discharged from inside the mounting protective frame 15 and the protective outer frame 14 and moved to the water surface. During detection, depending on the parameters to be detected, the corresponding 24 can be controlled by 37 to move one or more of the pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 downwards into the water flow to affect the water flow. The various parameters detected by the pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 are transmitted to the controller 37 and wirelessly sent to the user via the wireless module 38. After the pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 have completed their detection, the motor 13 is started, driving the drive control gear 32 to rotate, causing the first rotating arm 22, the second rotating arm 27, and the third rotating arm 31 to return to the mounting and protective frame 15. During use, the photovoltaic panel 36 generates electricity to power the equipment.The controller 37 and the wireless module 38 are protected by the sealing plate 34 and the protective mounting frame 35.

[0042] The drive control gear 32 is rotatably mounted in the middle of the mounting protective frame 15. The drive end of the motor 13 is fixedly connected to the upper middle of the drive control gear 32. The arc-shaped gear disk 28 is rotatably mounted on the mounting protective frame 15. The sliding mounting plate 18 is slidably engaged with the sliding limit plate 5. By sliding the sliding mounting plate 18 off the sliding limit plate 5, the first detection device 1 and the second detection device 3 can be easily removed from the first interceptor 7 and the second interceptor 8.

[0043] like Figure 9 As shown, the power generation protection unit 11 includes a fixed support frame 33, a sealing plate 34, a protective mounting frame 35, a photovoltaic panel 36, a controller 37, and a wireless module 38. The sealing plate 34 is fixedly installed on the upper end of the protective mounting frame 35. The photovoltaic panel 36 is evenly fixed on the protective mounting frame 35. The fixed support frame 33 is fixedly installed on the upper end of the sealing plate 34 by bolts. The controller 37 and the wireless module 38 are fixedly installed on the bottom end of the sealing plate 34. The photovoltaic panel 36 enables the device to automatically generate electricity.

[0044] The pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 are all wirelessly connected to the controller 37, which allows the various detected parameters to be calculated, processed, and then wirelessly transmitted.

[0045] The working principle of Example 1 is as follows: First, the upper end of the fixing pin 6 is pressed by external force, so that the bottom of the fixing pin 6 is inserted into the designated river water flow. The first interceptor 7 and the second interceptor 8 can be folded and rotated to adjust the installation interception range of the first interceptor 7 and the second interceptor 8. When the bottom end of each fixing pin 6 is inserted into the interior of the river, the first interceptor 7 and the second interceptor 8 can be fixedly installed at the designated river detection position. After the first interceptor 7 and the second interceptor 8 are fixedly installed at the designated position, the sliding mounting plate 18 in the first detection device 1 and the second detection device 3 can be slidably engaged with the sliding limit plate 5, so that the first detection device 1 and the second detection device 3 can be slidably engaged at the ends of the first interceptor 7 and the second interceptor 8. The first detection device 1 and the second detection device 3 can float on the water surface being detected. The first detection device 1 and the second detection device 3 can be easily removed from the first interceptor 7 and the second interceptor 8 by sliding the sliding mounting plate 18 off the sliding limit plate 5.

[0046] During use, the first interceptor 7 and the second interceptor 8 can intercept larger impurities floating in the water flow, allowing the impurities floating in the river to be intercepted and cleaned. The motors 13 in the first and second detection devices 1 and 3 are periodically activated, driving the drive control gear 32 to rotate. The rotating drive control gear 32 drives the three arc-shaped gear discs 28 to rotate synchronously. The rotating arc-shaped gear discs 28 synchronously drive the first rotating arm 22, the second rotating arm 27, and the third rotating arm 31 to rotate from inside the protective frame 15 and out of the mounting slots of the protective frame 15. This causes the various fixed frames 23, electric push rods 24, and the pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 to be discharged from inside the protective frame 15 and the outer protective frame 14 and moved to the water surface. During detection, the controller 37 can control the corresponding electric push rod 24 to operate according to the parameters to be detected, thus adjusting the pH... One or more of the sensors 20, 21, 25, 26, 29, and 30 move downwards into the water flow to detect the water flow. The various parameters detected by the sensors 20, 21, 25, 26, 29, and 30 are transmitted to the controller 37 and wirelessly transmitted to the user via the wireless module 38. After the sensors 20, 21, 25, 26, 29, and 30 have completed their detection, the motor 13 is started to drive the drive control gear 32 to rotate, so that the first rotating arm 22, the second rotating arm 27, and the third rotating arm 31 are reset in the protective frame 15. During use, the photovoltaic panel 36 can generate electricity to power the operation of the device. The controller 37 and the wireless module 38 are protected by the sealing plate 34 and the protective mounting frame 35.

[0047] A monitoring method for a river water environment monitoring device includes the following steps:

[0048] S1. First, press the upper end of the fixing pin 6 with external force so that the bottom of the fixing pin 6 is inserted into the designated river water flow. The first interceptor 7 and the second interceptor 8 can be folded and rotated to adjust the installation interception range of the first interceptor 7 and the second interceptor 8. When the bottom of each fixing pin 6 is inserted into the interior of the river, the first interceptor 7 and the second interceptor 8 can be fixedly installed at the designated river detection position. After the first interceptor 7 and the second interceptor 8 are fixedly installed at the designated position, the first detection device 1 and the second detection device 3 can be slidably locked onto the sliding limit plate 5 by sliding the sliding mounting plate 18 in the first detection device 1 and the second detection device 3. The first detection device 1 and the second detection device 3 can float on the water surface being detected. The first detection device 1 and the second detection device 3 can be easily removed from the first interceptor 7 and the second interceptor 8 by sliding the sliding mounting plate 18 off the sliding limit plate 5.

[0049] S2. During use, the first interceptor 7 and the second interceptor 8 can intercept larger impurities floating in the water flow, so that the impurities floating in the river can be intercepted and cleaned. The motors 13 in the first detection device 1 and the second detection device 3 are periodically started. The motors 13 can drive the drive control gear 32 to rotate. The rotating drive control gear 32 can drive the three arc-shaped toothed discs 28 to rotate synchronously. The rotating arc-shaped toothed discs 28 can synchronously drive the first rotating arm 22, the second rotating arm 27 and the third rotating arm 31 to rotate from inside the protective frame 15 and rotate out of the mounting groove of the protective frame 15. This allows the various fixed frames 23, electric push rods 24, pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29 and ammonia nitrogen sensor 30 to be discharged from inside the protective frame 15 and the protective outer frame 14 and move to the water surface.

[0050] S3. During detection, the corresponding electric push rod 24 can be controlled by the controller 37 to operate according to the parameters to be detected. This causes one or more of the following sensors—pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30—to move downwards into the water flow to detect the water flow. The various parameters detected by the pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30—are transmitted to the controller 37 and wirelessly to the detection system via the wireless module 38. The device wirelessly transmits detection information. After the pH sensor 20, dissolved oxygen sensor 21, turbidity sensor 25, conductivity sensor 26, temperature sensor 29, and ammonia nitrogen sensor 30 have completed their detection, the motor 13 is started to drive the drive control gear 32 to rotate, so that each of the first rotating arms 22, the second rotating arm 27, and the third rotating arm 31 can be reset into the mounting and protective frame 15. During use, the photovoltaic panel 36 can generate electricity to provide power for the operation of this device. The controller 37 and the wireless module 38 can be protected by the sealing plate 34 and the protective mounting frame 35.

[0052] Based on Example 1, such as Figure 10 As shown, a conical protective cover 10 is fixedly installed on the upper end of the fixed support frame 33, and the material of the conical protective cover 10 is transparent plastic.

[0053] In implementing this embodiment, a conical protective cover 10 is provided at the upper end of the fixed support frame 33 to prevent rain and protect the equipment for long-term use. The conical protective cover 10 is made of transparent plastic and does not affect the operation of the photovoltaic panel 36.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

9. A monitoring method for a river water environment monitoring device, using the river water environment monitoring device as described in claim 8, characterized in that, It includes the following steps: S1. First, press the upper end of the fixing pin (6) with external force so that the bottom of the fixing pin (6) is inserted into the designated river flow. Then, fold and rotate the first interceptor (7) and the second interceptor (8) to adjust the installation interception range of the first interceptor (7) and the second interceptor (8).

After the first interceptor (7) and the second interceptor (8) are fixedly installed at the designated position, the first... The sliding mounting plate (18) in the detection device (1) and the second detection device (3) is slidably engaged with the sliding limiting plate (5), so that the first detection device (1) and the second detection device (3) are slidably engaged at the ends of the first interceptor (7) and the second interceptor (8), and the first detection device (1) and the second detection device (3) float on the water surface being detected. The first detection device (1) and the second detection device (3) are removed from the first interceptor (7) and the second interceptor (8) by sliding the sliding mounting plate (18) from the sliding limiting plate (5); S2. During use, the first interceptor (7) and the second interceptor (8) intercept the floating impurities in the water flow, so that the floating impurities in the river can be intercepted and cleaned. The motor (13) in the first detection device (1) and the second detection device (3) is started periodically. The motor (13) drives the drive control gear (32) to rotate. The rotating drive control gear (32) drives the three arc-shaped toothed discs (28) to rotate synchronously. The rotating arc-shaped toothed discs (28) can synchronously drive the first rotating arm (22), the second rotating arm (27) and the third rotating arm (31) to rotate inside the installation protective frame (15) and rotate out from the installation slot of the installation protective frame (15).

S3. During detection, the controller (37) controls the corresponding electric push rod (24) to operate according to the parameters to be detected, so that one or more of the pH sensor (20), dissolved oxygen sensor (21), turbidity sensor (25), conductivity sensor (26), temperature sensor (29) and ammonia nitrogen sensor (30) move downwards into the water flow to detect the water flow. The various parameters detected by the pH sensor (20), dissolved oxygen sensor (21), turbidity sensor (25), conductivity sensor (26), temperature sensor (29) and ammonia nitrogen sensor (30) are transmitted to the controller (37), and the detection information is wirelessly sent to the detector via the wireless module (38). When the pH sensor (20), dissolved oxygen sensor (21), turbidity sensor (25), conductivity sensor (26), temperature sensor (29) and ammonia nitrogen sensor (30) are detected, the corresponding electric push rod (24) moves downwards into the water flow to detect the water flow. After the temperature sensor (25), conductivity sensor (26), temperature sensor (29) and ammonia nitrogen sensor (30) have completed their detection, the motor (13) is started to drive the drive control gear (32) to rotate so that each of the first rotating arms (22), the second rotating arm (27) and the third rotating arm (31) can be reset into the mounting protective frame (15).
