Description

Technical Field

[0001] The present application belongs to the technical field of water quality detection, and specifically relates to a water quality detection device for water conservancy projects. Background Art

[0002] As core infrastructure for regulating water resource allocation, ensuring flood control and drought relief, and supporting agricultural irrigation and urban and rural water supply, the operational status of water conservancy projects is closely linked to water quality. Water conservancy projects fulfill multiple water supply tasks, including domestic water, agricultural irrigation, and industrial water. Whether water quality meets standards is directly related to human health, crop growth, and industrial production safety. For example, excessive levels of heavy metals and pesticide residues in irrigation water can contaminate soil and affect crop quality; excessive levels of microorganisms or chemicals in drinking water pose a threat to public health. Water quality testing can accurately identify the types and concentrations of pollutants, ensuring that water resource utilization meets relevant standards and providing data support for the rational allocation of water resources.

[0003] Water quality testing is a crucial component of water conservancy projects, ensuring safe operation, rational water resource utilization, and ecological and environmental protection. However, existing water quality testing devices face numerous limitations in practical applications: The sampling mechanisms of traditional testing devices often struggle to flexibly acquire water samples at varying depths. Most can only collect water from the surface or at fixed depths, failing to comprehensively reflect water quality at different vertical levels. This makes it difficult to meet the complex water quality testing requirements of water conservancy projects. Summary of the Invention

[0004] The purpose of this application is to provide a water quality detection device for use in water conservancy projects to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A water quality detection device for water conservancy projects, comprising:

[0007] A buoy is provided with a bottom plate installed on the top of the buoy, brackets are welded to the four corners of the top of the bottom plate, a photovoltaic panel is installed on the top of the bracket, a detection box is provided below the photovoltaic panel, the detection box is installed on the top of the bottom plate, a plurality of heat dissipation slots are opened on the top of the detection box, and an extraction mechanism is provided inside the detection box;

[0008] The extraction mechanism includes a mounting frame, which is installed on the bottom side of the detection box. A winding drum is rotatably connected to the mounting frame. A self-locking motor is installed on one side of the mounting frame. A water tank is provided on the inside of the detection box. A pipe is wound around the winding drum. A high-pressure pump is installed on one side of the water tank. A drain pipe is provided on the detection box. A solenoid valve is installed on the drain pipe. A through hole is opened on the inside of the float, and a cleaning detection mechanism is provided inside the water tank.

[0009] Preferably, the cleaning and detection mechanism includes a bidirectional screw rod, which is rotatably connected to the inside of the water tank, and a turbine blade is movably installed on the bidirectional screw rod. The rear side of the turbine blade is rotatably connected to a ring, and the ring is sleeved on the bidirectional screw rod. A connecting rod is fixedly connected to the ring, and a scraper is installed at the end of the connecting rod. A water quality sensor is installed at the bottom inside the water tank.

[0010] Preferably, the self-locking motor is transmission-connected to the winding drum, and the end of the drain pipe extends to the inside of the water tank.

[0011] Preferably, a water pumping joint is installed at one end of the pipeline, and the other end of the pipeline is connected to a high-pressure pump. A retaining net is provided on the outer side of the water pumping joint.

[0012] Preferably, the through hole completely passes through the float and extends to the interior of the detection box, and the water pumping joint is arranged inside the through hole.

[0013] Preferably, the bidirectional screw rod is horizontally arranged inside the water tank, and the bidirectional screw rod is arranged on one side of the high-pressure pump.

[0014] Preferably, the scraper is attached to the inner wall of the water tank, and the water quality sensor is arranged below the scraper.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) Through the setting of the extraction mechanism, when testing water quality, the self-locking motor drives the reel on the mounting frame to rotate, so that the reel controls the reeling and unreeling of the pipe, and moves the pumping joint to different depths of the water body, so that the high-pressure pump cooperates with the pipe and the pumping joint to extract the liquid in the water body at the corresponding depth; by adopting this design, by extracting liquid from water bodies at different depths for testing, water samples at different vertical levels can be obtained, breaking the limitation of single-depth sampling, and more comprehensively reflecting the three-dimensional water quality status of the water body. At the same time, the flexibility and adaptability of the detection operation are enhanced. The same set of equipment can meet the sampling needs of different depths without the need to replace the sampling equipment, simplifying the detection process, improving the adaptability to different water environments (such as lakes and rivers of different depths), and reducing the equipment investment cost of multi-scene detection.

[0017] (2) Through the setting of the extraction mechanism and the cleaning and detection mechanism, when testing the water quality, the water pumping joint is moved to different depths of the water body, so that the high-pressure pump cooperates with the pipeline and the water pumping joint to extract the liquid in the water body of the corresponding depth. At this time, the solenoid valve on the drain pipe is opened to continuously inject the liquid into the water tank to flush the inside of the water tank. The liquid continuously injected into the water tank will drive the turbine blades to rotate, so that the turbine blades continue to move on the bidirectional screw rod. When the turbine blades move, they will drive the ring to move, so that the ring drives the scraper to clean the inside of the water tank. After the above operation is continued for a period of time, the valve is closed. Close the solenoid valve and start the water quality sensor to detect the water quality; use water of the corresponding depth for flushing to avoid interference from impurities at other depths. At the same time, liquid flushing and scraper mechanical cleaning form a dual effect, which can effectively remove stains, microorganisms or water residues from the previous test on the inner wall of the water tank; and liquid flushing at the corresponding depth ensures that the water tank and detection-related components are in the "same depth water environment" before testing, reducing the interference of foreign pollutants on the sample, making the test data obtained by the water quality sensor more in line with the actual water conditions, and improving the accuracy of water quality testing.

[0027] Example 1:

[0028] See also Figure 1-Figure 3 As shown, a water quality detection device for water conservancy projects includes:

[0029] A buoy 1 is provided with a bottom plate 2 mounted on the top of the buoy 1. Brackets 3 are welded to the four corners of the top of the bottom plate 2. A photovoltaic panel 4 is mounted on the top of the bracket 3. A detection box 5 is provided below the photovoltaic panel 4. The detection box 5 is mounted on the top of the bottom plate 2. A plurality of heat dissipation slots 6 are provided on the top of the detection box 5. An extraction mechanism 7 is provided inside the detection box 5.

[0030] As can be seen from the above, when in use, the float 1 is placed inside the water body, and the built-in battery is recharged through the photovoltaic panel 4 on the top so that the device can be used for a long time. Subsequently, the liquid at different depths in the water body is extracted through the extraction mechanism 7 inside the detection box 5, thereby facilitating the detection of liquid at different depths in the water body (in the idle part of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive controllers and power supplies, are connected through wires. For specific connection methods, refer to the following working principle. The electrical connection is completed in the order of working between each electrical component. The detailed connection methods are well known in the art).

[0031] Specifically, regarding the above extraction mechanism 7, refer to Figure 4 and Figure 5As shown, the extraction mechanism 7 includes a mounting frame 8, which is mounted on the bottom side of the detection box 5. A take-up drum 9 is rotatably connected to the mounting frame 8. A self-locking motor 10 is installed on one side of the mounting frame 8. A water tank 11 is provided inside the detection box 5. A pipe 12 is wound around the take-up drum 9. A high-pressure pump 13 is installed on one side of the water tank 11. A drain pipe 14 is provided on the detection box 5. A solenoid valve 15 is installed on the drain pipe 14. A through hole 16 is opened on the inside of the float 1, and a cleaning detection mechanism 19 is provided inside the water tank 11.

[0032] As can be seen from the above, during water quality testing, the self-locking motor 10 drives the winding drum 9 on the mounting frame 8 to rotate, so that the winding drum 9 controls the winding and unwinding of the pipe 12, thereby moving the bottom end of the pipe 12 to the corresponding water body depth. At this time, the liquid is pumped into the water tank 11 by the high-pressure pump 13, and then the inside of the water tank 11 is continuously flushed by the cleaning and detection mechanism 19 inside the water tank 11. The flushing liquid is discharged through the drain pipe 14, which facilitates the detection of water bodies at different depths and improves the accuracy of the detection.

[0033] Preferably, the self-locking motor 10 is in transmission connection with the winding drum 9, and the end of the drain pipe 14 extends to the inside of the water tank 11;

[0034] As can be seen from the above, the self-locking motor 10 drives the winding drum 9 to rotate, thereby controlling the winding drum 9 to reel in and out; the end of the drain pipe 14 is extended to the inside of the water tank 11 to facilitate the discharge of water inside the water tank 11.

[0035] Preferably, a water pumping joint 17 is installed at one end of the pipe 12, and the other end of the pipe 12 is connected to the high-pressure pump 13. A retaining net 18 is provided on the outer side of the water pumping joint 17.

[0036] From the above, it can be seen that by moving the water pumping connector 17 to different depths of the water body, the high-pressure pump 13 cooperates with the pipeline 12 and the water pumping connector 17 to extract liquid from water bodies at different depths. At the same time, by the baffle 18 arranged on the outside of the water pumping connector 17, foreign matter or other objects in the water body are prevented from entering the interior of the pipeline 12, thereby avoiding blockage of the pipeline 12.

[0037] Preferably, the through hole 16 completely passes through the buoy 1 and extends to the interior of the detection box 5, and the water pumping connector 17 is arranged inside the through hole 16;

[0038] As can be seen from the above, the through hole 16 facilitates the unwinding movement of the pipe 12 and the water pumping joint 17 .

[0039] Example 2:

[0040] refer to Figure 6As shown, the cleaning detection mechanism 19 includes a bidirectional screw rod 20, which is rotatably connected to the inside of the water tank 11. A turbine blade 21 is movably installed on the bidirectional screw rod 20. A collar 22 is rotatably connected to the rear side of the turbine blade 21. The collar 22 is sleeved on the bidirectional screw rod 20. A connecting rod 23 is fixedly connected to the collar 22. A scraper 24 is installed at the end of the connecting rod 23. A water quality sensor 25 is installed at the bottom of the inner side of the water tank 11.

[0041] As can be seen from the above, when testing water quality, liquid of different depths is extracted by the high-pressure pump 13, so that the liquid is continuously injected into the water tank 11 to flush the inside of the water tank 11, and the liquid continuously injected into the water tank 11 will drive the turbine blades 21 to rotate, so that the turbine blades 21 continue to move on the bidirectional screw 20, and when the turbine blades 21 move, it will drive the ring 22 to move, so that the ring 22 drives the scraper 24 to clean the inside of the water tank 11; after continuing the above operation for a period of time, the water quality sensor 25 is started, so that the water quality sensor 25 detects the water quality.

[0042] Preferably, the bidirectional screw rod 20 is horizontally arranged inside the water tank 11, and the bidirectional screw rod 20 is arranged on one side of the high-pressure pump 13;

[0043] As can be seen from the above, the bidirectional screw 20 is set on one side of the high-pressure pump 13, so that after the high-pressure pump 13 extracts liquid, the liquid can be sprayed directly on the bidirectional screw 20, so that the sprayed liquid can drive the turbine blades 21 to rotate.

[0044] Preferably, the scraper 24 is attached to the inner wall of the water tank 11, and the water quality sensor 25 is arranged below the scraper 24;

[0045] As can be seen from the above, when the scraper 24 moves, it can clean the inner wall of the water tank 11 and the top probe of the water quality sensor 25 at the same time.

[0046] Working principle: When monitoring water quality, the buoy 1 is placed inside the water body, and the built-in battery is recharged through the photovoltaic panel 4 on the top so that the device can be used for a long time; then the self-locking motor 10 drives the winding drum 9 on the mounting frame 8 to rotate, so that the winding drum 9 controls the winding and unwinding of the pipe 12, and the water pumping joint 17 is moved to different depths of the water body, so that the high-pressure pump 13 cooperates with the pipe 12 and the water pumping joint 17 to extract the liquid in the water body at the corresponding depth. At this time, the solenoid valve 15 on the drain pipe 14 is opened, and the liquid is continuously injected into the water tank 11 to flush the inside of the water tank 11. The liquid continuously injected into the water tank 11 will drive the turbine blades 21 to rotate, so that the turbine blades 21 continue to move on the bidirectional screw 20, and when the turbine blades 21 move, it will drive the ring 22 to move, so that the ring 22 drives the scraper 24 to clean the inside of the water tank 11. After the above operation continues for a period of time, the solenoid valve 15 is closed, and the water quality sensor 25 is started, so that the water quality sensor 25 detects the water quality.

[0047] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
