[0002] With the increasing demands for water resource management and environmental protection, water quality monitoring technology has become a core tool in water conservancy projects, ecological protection, and pollution control. Currently, pumped-storage power stations primarily use fixed or single-point sensors for water quality monitoring. These sensors acquire water quality parameters such as pH, dissolved oxygen, turbidity, and conductivity by collecting water samples at fixed points or deploying sensors at a single depth.

[0003] There are already various water quality monitoring devices on the market, such as buoy-based water quality monitoring devices and IoT-based water quality monitoring platforms. However, these devices still have some shortcomings when monitoring water quality. For example, some systems can only monitor water quality parameters on the surface of the water body and cannot perform stratified monitoring of water quality in different depth areas. The data they detect is singular and cannot reflect the water quality situation in different depth areas of the water body, resulting in an incomplete and inaccurate monitoring of water quality.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention allows for adjustment of the water depth at the sampling end by winding and unwinding the wire rope via a horizontal axis, enabling sampling operations at different water depths and resulting in richer and more comprehensive water quality sampling.

[0019] When the third drive motor drives the second lifting column to move downward, it will also drive the sealing plate to move towards the water inlet. Water is gradually injected into the water storage pipe, and the sealing plate gradually blocks the water inlet. When the water storage pipe finishes taking water, the sealing plate completely blocks the water inlet, preventing water from other water depths from being injected into the water storage pipe when the sampling end is moved later, thus ensuring the accuracy of water quality testing at different water depths.

[0020] When the detection end and the sampling end are connected, the water receiving component can automatically extract the water quality sample stored inside the buffer tube for convenient use. At the same time, when the detection end and the sampling end are not connected, both the buffer tube and the water receiving component are sealed to prevent water from seeping in and affecting the detection effect.

[0021] A water droplet falls onto the pH test strip. An electric telescopic rod shortens, moving the pH test strip below the blocking disc and then below the color sensor. The color sensor detects the color of the pH test strip to determine the pH range of the water. This allows for both pH detection and comparison with the pH value detected by the water quality sensor. By observing the accuracy of the water quality sensor after prolonged use, it can be determined whether the pH sensor needs to be replaced to avoid detection errors.

[0022] The detection end can control the sampling end to move to different depths in the water, realizing multi-level sampling and testing of water quality. The samples are richer and more comprehensive, allowing for more comprehensive testing of water quality. At the same time, when the detection end and the sampling end are connected, the sampling end can automatically pick up the sample and perform testing. Furthermore, the sampling is measured upwards from the bottom of the detection end as a reference point. Since the bottom point remains fixed, the upward sampling distance will not change due to the decrease in water volume. This is conducive to long-term fixed-point sampling and testing of water quality, and facilitates accurate comparison of changes in water quality at a certain depth in the future.

[0023] Therefore, this utility model has the advantage of being able to monitor water quality at different depths within a body of water, providing a more comprehensive and accurate picture of the water quality. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0039] Example. A multi-level regional water quality monitoring device for water utilization, such as... Figure 1-13 As shown, it includes a detection end 1 and a sampling end 2, with the sampling end 2 installed at the movable end of the detection end 1. The detection end 1 is submerged at the bottom of the water, while the sampling end 2 floats in the water.

[0040] like Figure 2 and 3 As shown, the detection end 1 includes a sinking plate 11, a cover 12 is installed on the top of the sinking plate 11, and a sealing gasket is installed at the joint between the sinking plate 11 and the cover 12. A horizontal shaft 18 is rotatably installed on the top of the sinking plate 11 via a bearing. Steel wire ropes 13 are installed on both ends of the horizontal shaft 18 via winding discs. Through holes for the steel wire ropes 13 to pass through are opened on both sides of the top of the cover 12. At the same time, a sealing sleeve is installed inside the through hole. A second drive motor 17 for driving the horizontal shaft 18 to rotate is also installed on the top of the sinking plate 11. The drive end of the second drive motor 17 is connected to one end of the horizontal shaft 18. A water receiving component 16 for monitoring water quality is installed on one side of the top of the sinking plate 11. The water inlet end of the water receiving component 16 is on the same plane as the top of the cover 12. A controller, power supply, etc. are also installed on the top of the sinking plate 11.

[0041] like Figure 7 The sampling end 2 includes a base plate 21, a central chamber 23 is installed on the top of the base plate 21, and a sealing gasket is installed at the joint between the base plate 21 and the central chamber 23. Rope connecting seats 231 are installed on both sides of the central chamber 23, and the rope connecting seats 231 on the same side are connected to the wire rope 13. The horizontal shaft 18 is driven by the drive motor 2 17 to rotate. The rotation of the horizontal shaft 18 will perform winding and unwinding operations on the wire rope 13. When the wire rope 13 is wound up, the sampling end 2 is pulled down, causing the sampling end 2 to move towards the bottom of the water. When the wire rope 13 is unwound, the sampling end 2 floats and moves towards the water surface under the buoyancy of the floating airbag 243. Therefore, the depth of the sampling end 2 in the water can be adjusted by winding and unwinding the wire rope 13 through the horizontal shaft 18, and sampling operations can be performed on water at different depths, resulting in richer and more comprehensive water quality sampling.

[0042] like Figure 9 and 10A top seat 25 is installed on the top of the central compartment 23. A floating assembly 24 is installed on the top of the central compartment 23 and on the outer ring of the top seat 25. A water inlet 251 is provided on the top of the top seat 25, and a drain outlet is provided on the top of the top seat 25 and on one side of the water inlet 251. A device cavity 252 is provided at the bottom of the top seat 25, connecting the interior of the central compartment 23 with the interior of the water inlet 251. An arc-shaped guide edge 253 is provided on one side of the device cavity 252. The device cavity 252 is close to the arc-shaped guide edge 253. An arc-shaped guide plate 254 is fixed on one side. A water pump drive source 27 is installed inside the middle compartment 23. A water pump assembly 26 is fixed to the drive end of the water pump drive source 27, and the water pump assembly 26 and the water inlet 251 are coaxially arranged. A linkage frame 28 is installed on the movable end of the water pump assembly 26. A blocking plate 29 for blocking the water inlet 251 is installed on the end of the linkage frame 28 away from the water pump assembly 26, and the blocking plate 29 is located between the arc-shaped guide plate 254 and the arc-shaped guide edge 253. The structure is as follows. Figure 11 .

[0043] The detection end 1 can control the sampling end 2 to move the sampling end 2 to different depths in the water area, realizing multi-level sampling and testing of water quality. The samples are richer and more comprehensive, and the water quality can be tested more comprehensively. At the same time, when the detection end 1 is connected to the sampling end 2, the sampling end 2 can automatically receive the sample and perform testing. Furthermore, the upward sampling is measured with the bottom of the detection end 1 as the reference point. Since the bottom point remains unchanged, the upward sampling distance will not change due to the decrease in water volume. This is conducive to long-term fixed-point sampling and testing of water quality, and facilitates accurate comparison of changes in water quality at a certain depth in the later stage.

[0044] like Figure 8 The floating assembly 24 includes a T-shaped pod seat 241 installed on the top of the central pod 23, and the central part of the T-shaped pod seat 241 is provided with a through cavity for the top seat 25 to pass through. Fixing buckles 242 are installed on all four sides of the outer wall of the T-shaped pod seat 241. A limiting bladder is formed between the bottom protruding edge of the T-shaped pod seat 241 and the four fixing buckles 242, and a floating airbag 243 is installed inside the limiting bladder.

[0045] like Figure 12 and 13 The water pump assembly 26 includes a water storage pipe 261 fixed inside the equipment cavity 252. A second lifting column 262 is installed inside the water storage pipe 261. A sealing ring 264 is installed at the top of the second lifting column 262, and the sealing ring 264 abuts against the inner wall of the water storage pipe 261. The function of the sealing ring 264 is to prevent water from entering the gap between the water storage pipe 261 and the second lifting column 262. An L-shaped connecting pipe 263 is welded to the outlet on one side of the water storage pipe 261, and the outlet end of the L-shaped connecting pipe 263 is located below the bottom plate 21. A buffer pipe 265 is detachably installed at the outlet end of the L-shaped connecting pipe 263.

[0046] The top end of the buffer tube 265 is welded with an external threaded sleeve 2655. The outlet end of the L-shaped connecting tube 263 has a threaded cavity that is threadedly connected to the external threaded sleeve 2655. A T-shaped hole ring 2654 is fixed in the inner cavity of the external threaded sleeve 2655. A retaining ring 2651 is fixed at the bottom end of the buffer tube 265. A T-shaped frustum 2652 is engaged in the inner hole of the retaining ring 2651. A spring 2653 is installed between the T-shaped hole ring 2654 and the T-shaped frustum 2652. When the water sample is stored inside the buffer tube 265, the spring 2653 resists the T-shaped frustum 2652, causing the T-shaped frustum 2652 to block the inner hole of the retaining ring 2651, thus preventing the water sample from being discharged from the inner hole of the retaining ring 2651.

[0047] The pump drive source 27 includes two motor frames, a third drive motor 271 mounted on the motor frames, and two limiting seats 273 installed inside the middle compartment 23. A rack 274 is vertically slidably mounted on the vertical end face of the limiting seat 273, and the rack 274 is fixed to the bottom of the second lifting column 262. The drive end of the third drive motor 271 is equipped with a gear 272 that meshes with the rack 274.

[0048] The linkage frame 28 includes a rotating shaft 284 rotatably mounted inside the central compartment 23, and a fixing ring 281 fitted onto the bottom end of the lifting column 262. Both ends of the rotating shaft 284 are rotatably mounted with rocker plates 283. Vertical bars 282 are mounted on both protruding ends of the fixing ring 281, and the bottom ends of the vertical bars 282 are rotatably connected to one end of the rocker plate 283. Two linkage bars 285 are rotatably mounted on the other end of the rocker plate 283. A connecting shaft 286 is provided between the two linkage bars 285, and a sealing plate 29 is fixed to the connecting shaft 286. When the rack 274 drives the lifting column 262 downward, the fixing ring 281 drives the vertical bars 282 downward. Because the rocker plate 283 is rotatably mounted on the rotating shaft 284, the downward movement of the vertical bars 282 causes the end of the rocker plate 283 closest to it to move downward, moving the rocker plate 283 away from the vertical bars. One end of bar 282 is lifted downwards, and through the cooperation of linkage bar 285 and connecting shaft 286, the sealing plate 29 moves along the arc guide plate 254 and arc guide edge 253 towards the water inlet 251. The sealing plate 29 then blocks the water inlet 251 and seals the top of the water storage pipe 261. When the drive motor 271 drives the lifting column 262 downwards, it also drives the sealing plate 29 to move towards the water inlet 251. Water is gradually injected into the water storage pipe 261, and the sealing plate 29 gradually blocks the water inlet 251. When the water storage pipe 261 finishes taking water, the sealing plate 29 completely blocks the water inlet 251, preventing water from other water depths from being injected into the water storage pipe 261 when the sampling end 2 is moved later, thus ensuring the accuracy of water quality testing at different water depths.

[0049] like Figure 4 and 5 As shown, the water receiving assembly 16 includes a pad mounted on the top of the sinking plate 11 and a drive motor 161 mounted on the top of the pad, as well as a T-shaped cylinder 166 mounted on the top of the inner wall of the cover 12. A baffle plate 163 is mounted at the bottom of the T-shaped cylinder 166, and a color sensor 164 and an LED light are mounted at the bottom of the baffle plate 163. A lifting column 1610 is provided at the top of the T-shaped cylinder 166. A T-shaped cavity 1611 is opened at the center of the top of the lifting column 1610. An annular seat 1613 is fixed at the center of the bottom of the lifting column 1610. The annular seat 1613 is slidably mounted with a sliding sleeve opened at its bottom. A water-lifting rod 1614 is provided, with its top end located inside the T-shaped cavity 1611. A water storage cavity 169 is provided on the top of the annular seat 1613. A buffer cavity 1612 is provided on the upper side of the periphery of the water-lifting rod 1614. An electric telescopic rod 162 is installed on the drive end of the drive motor 161. A V-shaped crossbar 167 is installed on the movable end of the electric telescopic rod 162. A suction cup 168 and a water quality sensor are respectively installed on the top of the two corners of the crossbar 167. The water outlet of the water storage cavity 169 is located directly above the suction cup 168. At the same time, a reserved hole is provided on the top of the blocking plate 163 for the crossbar 167 to pass through.

[0050] A spring 1615 is fixed between the top of the blocking plate 163 and the bottom of the lifting column 1610. A spring cavity is opened at the bottom of the water-lifting rod 1614, and a spring 2 1616 is installed between the water-lifting rod 1614 and the top of the blocking plate 163 through the spring cavity. The strength of the spring 2 1616 is greater than that of the spring 1615. When the detection end 1 is connected to the sampling end 2, the water receiving component 16 can automatically extract the water quality sample stored inside the buffer tube 265 for convenient use. At the same time, when the detection end 1 and the sampling end 2 are not connected, the buffer tube 265 and the water receiving component 16 are both sealed to prevent water from seeping in and affecting the detection effect.

[0051] like Figure 6As shown, a test strip storage cylinder 165 is installed at the bottom of the blocking disc 163 and on the side near the electric telescopic rod 162. A rubber ring 1617 is detachably installed on the top of the test strip storage cylinder 165 by bolts. Three protruding teeth 1618 are installed at equal intervals on the inner ring of the rubber ring 1617. A spring 1619 is installed on the upper side of the inside of the test strip storage cylinder 165. A pressure block is installed on one end of the spring 1619 near the rubber ring 1617. A pH test strip is placed inside the test strip storage cylinder 165 and between the pressure block and the rubber ring 1617. When the suction cup 168 is rotated to be directly below the test strip storage cylinder 165, the suction cup 168 is driven to move upward and adhere to the pH test strip suction cup at the bottom of the test strip storage cylinder 165. When the suction cup 168 is moved downward, the pH test strip is pulled out from the inside of the test strip storage cylinder 165, realizing the automatic feeding of pH test strips. When the pH test strip decreases, spring three 1619 moves downward against the test strip, pressing the pH test strip against the top of the rubber ring 1617. Alternatively, the horizontal bar 167 can be rotated by drive motor one 161. When water drips onto the water quality sensor, the pH test strip is immediately rotated to the outlet of the water storage chamber 169, allowing water to fall onto the pH test strip. The electric telescopic rod 162 then shortens, moving the pH test strip below the blocking plate 163 and below the color sensor 164. The color sensor 164 detects the color of the pH test strip to determine the pH range of the water. This allows for both pH detection and comparison with the pH value detected by the water quality sensor. By observing the detection accuracy of the water quality sensor after long-term use, it can be determined whether the pH sensor needs to be replaced to avoid detection errors.

[0052] The top of the detection end 1 has three triangular bevels 14 on one side. A sealing chamber 15 is installed on the top of the inner wall of the cover 12 and directly below each bevel 14. A positioning seat 22 is installed on the bottom of the base plate 21 and directly opposite each bevel 14. When the sampling end 2 moves downward, the positioning seat 22 first contacts the top of the cover 12. The bevels of the positioning seat 22 and the bevels 14 make it easier for the positioning seat 22 to pass through the bevels 14 and enter the interior of the sealing chamber 15. The positioning of the three bevels 14 and the positioning seat 22 ensures the accuracy of the contact between the detection end 1 and the sampling end 2 and avoids the occurrence of skew.

[0053] Working principle of this utility model

[0054] In use, the detection end 1 is submerged at the bottom of the water area to be tested, and the horizontal shaft 18 is driven by the drive motor 17 to rotate. The rotation of the horizontal shaft 18 will perform winding and unwinding operations on the wire rope 13. When the wire rope 13 is wound up, the sampling end 2 is pulled down, causing the sampling end 2 to move towards the bottom of the water. When the wire rope 13 is unwound, the sampling end 2 floats and moves towards the water surface under the buoyancy of the floating airbag 243.

[0055] After moving sampling end 2 to the desired sampling point, control the water pump assembly 26 to take a sample, as follows:

[0056] Drive motor 271 drives gear 272 to rotate. Under the meshing transmission of gear 272 and rack 274, it pushes lifting column 262 upward, pushing the water in water storage pipe 261 back into the water. Then, drive gear 272 to rotate in the opposite direction, causing rack 274 to move downward, which in turn drives lifting column 262 to move downward. Lifting column 262 releases its obstruction of water storage pipe 261, allowing water to enter the interior of water storage pipe 261 for storage. When the top of lifting column 262 is below the outlet of L-shaped connecting pipe 263, the interior of L-shaped connecting pipe 263 is connected to the interior of water storage pipe 261. The water in water storage pipe 261 will then enter the buffer pipe 265 for temporary storage through L-shaped connecting pipe 263.

[0057] When the rack 274 drives the lifting column 262 to move downward, the fixing ring 281 drives the vertical bar 282 to move downward. When the water storage pipe 261 finishes taking water, the sealing plate 29 also completely blocks the water inlet hole 251 to prevent water from other water depths from being injected into the inside of the water storage pipe 261 when the sampling end 2 is moved later.

[0058] After sampling is completed, when the wire rope 13 is wound up, the sampling end 2 is pulled down. When the sampling end 2 moves down, the positioning seat 22 first contacts the top of the cover 12. The setting of the positioning seat 22 and the bevel 14 makes it easier for the positioning seat 22 to pass through the bevel 14 and enter the interior of the sealed chamber 15.

[0059] When the detection end 1 comes into contact with the sampling end 2, the water receiving component 16 will collect the water sample from inside the buffer tube 265, as follows:

[0060] The bottom of the retaining ring 2651 abuts against the top of the lifting column 1610, and the bottom of the T-shaped frustum 2652 enters the interior of the T-shaped cavity 1611. As the retaining ring 2651 descends, it presses down on the lifting column 1610. Since the strength of spring 1616 is greater than that of spring 1615, when the retaining ring 2651 presses down on the lifting column 1610, spring 1615 will be compressed more under the same pressure, while spring 1616 will be compressed less. At this time, the annular seat 1613 gradually connects with the trapezoidal end of the T-shaped cavity 1611, and the T-shaped frustum is connected by the top water rod 1614. When 2652 is pushed upwards, the T-shaped frustum 2652 releases the blockage of the inner hole of the retaining ring 2651. The water inside the buffer tube 265 flows into the buffer chamber 1612 through the inner hole of the retaining ring 2651 and is stored inside the buffer chamber 1612. Then, the detection end 1 and the sampling end 2 are separated. Under the elastic action of the spring, the positions of the lifting column 1610, the top water rod 1614 and the T-shaped frustum 2652 are all reset. The water inside the buffer chamber 1612 is discharged through the water storage chamber 169 and drips onto the water quality sensor. The water quality is detected by the water quality sensor and the data is sent by the controller.
