Description

Technical Field

[0001] This invention relates to the field of water quality monitoring technology, and in particular to a water quality monitoring and analysis instrument. Background Technology

[0002] A COD water quality monitor is an instrument used to measure the chemical oxygen demand in water bodies. COD is an important indicator of water quality, representing the oxidation requirements of organic matter in the water and reflecting the degree of organic pollution. When using a COD water quality monitor, it primarily assesses the degree of organic pollution in water through chemical oxidation reactions. During the test, the instrument first mixes the water sample with multiple oxidants (such as potassium dichromate) and an acidic reagent (such as concentrated sulfuric acid). Strong oxidants oxidize the organic matter in the water sample in an acidic environment, consuming oxygen. To ensure a complete reaction, the instrument usually heats the water sample to a certain temperature to accelerate the oxidation reaction. After the reaction, the instrument calculates the COD value by measuring the remaining amount of oxidant or the color change in the water sample. The remaining oxidant is usually measured using photometry or titration, or the absorbance of the water sample (i.e., color change) is measured using a photometer, thus indirectly calculating the COD concentration in the water sample. Therefore, multiple reagent bottles are needed to store the reagents to meet the usage requirements.

[0003] Existing water quality monitors suffer from numerous and complex infusion tubes between reagent bottles and the monitor. These tubes are prone to tangling, bending, or crossing, affecting the smoothness of reagent delivery. Furthermore, tangling not only increases the risk of blockage during reagent delivery but also increases the difficulty of equipment maintenance, impacting the accuracy and stability of test results. Moreover, existing water quality monitors do not provide effective monitoring methods for infusion tube blockage. Due to the large number and complex arrangement of infusion tubes, and the presence of impurities in the liquid, blockage or obstruction is likely to occur after prolonged use. This blockage is often insidious and fails to be detected and addressed promptly, leading to insufficient or complete cessation of reagent flow, thus affecting the accuracy and timeliness of water quality testing, as well as the stable operation of the instrument and the accuracy of data. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a water quality monitoring and analysis instrument to solve the problems of existing water quality monitoring instruments, which have a large number of infusion tubes between the reagent bottles and the monitoring instrument and are arranged in a complex manner. These infusion tubes are prone to tangling, bending or crossing, which affects the smoothness of reagent delivery. At the same time, the tangling of infusion tubes not only increases the difficulty of equipment maintenance, but also makes it easy for the large number of infusion tubes and the complex arrangement to cause blockage or clogging after long-term use.

A limiting push plate is rotatably connected to the side wall of the sliding plate away from the compression spring. A compression plate is fixedly connected to one end of the limiting push plate. Multiple evenly distributed contact blocks are fixedly connected to the side wall of the limiting push plate and the side near the sliding plate.

A concave block is fixedly connected to the side wall of the limiting push plate. A magnet is fixedly connected inside the concave block. An iron block is fixedly connected to the side wall of the sliding plate near the compression spring, and the magnet and the iron block are in contact.

[0007] Preferably, the monitoring box has a communication opening at one end of its side wall near the extrusion plate. A toothed plate is slidably connected to one side of the monitoring box near the communication opening. One end of the toothed plate is arc-shaped. The side wall of the extrusion plate contacts one end of the toothed plate. A return spring is fixedly connected to the side wall of the toothed plate. One end of the return spring is fixedly connected to the side wall of the monitoring box. A gear meshes with the top of the toothed plate.

[0014] The beneficial effects of this invention are:

[0015] 1. A water quality monitoring and analysis instrument, wherein the limiting mechanism, during use, squeezes the delivery tube into an arc-shaped clamping plate, and then a compression block is squeezed by a telescopic spring. The compression block drives the arc-shaped clamping plate to rotate, thereby limiting the delivery tube. Simultaneously, it can clamp and limit delivery tubes of different widths, effectively organizing the infusion pipeline, ensuring smooth reagent delivery, facilitating subsequent equipment maintenance, and solving problems such as excessive number of delivery tubes, random placement, easy entanglement, excessive bending, or crossing that affect the smoothness of reagent delivery. Furthermore, the entanglement of delivery tubes not only increases the risk of blockage during reagent delivery but also increases the difficulty of equipment maintenance, affecting the accuracy and stability of test results. This instrument provides a mechanism to organize the delivery tubes, prevent entanglement and bending, ensure a clear and unobstructed reagent delivery path, reduce the risk of blockage, and lower the difficulty of equipment maintenance, thereby improving the uniformity and stability of reagent delivery.

[0016] 2. A water quality monitoring and analysis instrument, in which an anti-clogging mechanism is provided, wherein a flexible expansion bladder expands and pushes a limiting plate, the limiting plate further pushes a contact block, the contact block pushes a limiting push plate, and the limiting push plate pushes a toothed plate through a squeezing plate, thereby driving a striking hammer to strike a bell. This achieves the function of the anti-clogging mechanism to monitor the flow status of the delivery pipe in real time, promptly detect blockages and provide warnings. This solves the problem that due to the large number and complex arrangement of delivery pipes, and the presence of impurities in the liquid, blockages or blockages easily occur after prolonged use, leading to insufficient or complete stagnation of reagent flow, thus affecting the accuracy and timeliness of water quality testing, and further impacting the stable operation of the instrument. It achieves active monitoring and fault indication of the delivery pipe, enabling staff to quickly clear blocked delivery pipes in a timely manner, avoiding the impact of reagent delivery stagnation on the monitoring process, and significantly improving the stability and ease of maintenance of the equipment.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0030] like Figures 1 to 8 As shown, a water quality monitoring and analysis instrument includes a monitoring box 1. A water quality monitor 2 is fixedly connected to the top of the inner wall of the monitoring box 1. A partition 3 is fixedly connected between the two sides of the inner wall of the monitoring box 1. Multiple reagent bottles 4 are evenly placed at equal intervals on the top of the partition 3. Multiple wastewater recovery tanks 5 are placed on the bottom of the inner wall of the monitoring box 1. A water inlet pipe 38 is fixedly connected to the side wall of the monitoring box 1. A delivery pipe 6 is fixedly connected to the top of both the reagent bottles 4 and the wastewater recovery tanks 5. One end of the delivery pipe 6 is fixedly connected to the bottom of the water quality monitor 2. A flexible expansion bladder 7 is fixedly connected to the middle part of the delivery pipe 6. The inner wall of the monitoring box 1 is provided with a device for adjusting the delivery pipe 6. The limiting mechanism includes a limiting mechanism. The inner and outer walls of the monitoring box 1 are equipped with an anti-blocking mechanism to alert when the delivery pipe 6 is blocked. The limiting mechanism includes a mounting plate 8, which is fixedly connected to the inner wall of the monitoring box 1. Two sets of opposing fixing blocks 9 are fixedly connected to the side wall of the mounting plate 8. A connecting column 10 is fixedly connected between the opposing faces of the fixing blocks 9. Opposing arc-shaped clamping plates 11 are rotatably connected to the outer walls of both sides of the connecting column 10. A squeezing block 12 is fixedly connected to the opposite side of the arc-shaped clamping plate 11. A telescopic spring 13 is fixedly connected to the side wall of the squeezing block 12. One end of the telescopic spring 13 is fixedly connected to the side wall of the mounting plate 8.

[0031] When the limiting mechanism is in use, first connect both ends of the conveying pipe 6 to the water quality monitor 2 and the reagent bottle 4 or wastewater recycling tank 5 respectively. Then move the middle part of the conveying pipe 6 to the side wall of the arc-shaped clamp 11 and apply pressure to the conveying pipe 6. The outer wall of the conveying pipe 6 will squeeze the roller 35, and the roller 35 will squeeze the arc-shaped clamp 11. Then the arc-shaped clamp 11 will squeeze the telescopic spring 13 on the side wall through the squeezing block 12. When the conveying pipe 6 enters the interior of the arc-shaped clamp 11, the telescopic spring 13 will push the squeezing block 12. The squeezing block 12 will drive the arc-shaped clamp 11 to close, thereby limiting the conveying pipe 6 and thus achieving the function of regulating the conveying pipe 6. When the limiting mechanism is in use, the conveying pipe 6 is squeezed into the arc-shaped clamp 11, and then the squeezing block 12 is squeezed by the telescopic spring 13. The squeezing block 12 drives the arc-shaped clamping plate 11 to rotate, thereby limiting the delivery tube 6. At the same time, it can also clamp and limit delivery tubes 6 of different widths, effectively organizing the infusion pipeline, ensuring the smoothness of reagent delivery, and facilitating subsequent equipment maintenance. It solves the problems of excessive number of delivery tubes 6, random placement, easy entanglement, excessive bending or crossing, which affect the smoothness of reagent delivery. At the same time, the entanglement of delivery tubes 6 not only increases the risk of blockage during reagent delivery, but also increases the difficulty of equipment maintenance, affecting the accuracy and stability of test results. It has created a way to organize delivery tubes 6, prevent entanglement and bending, ensure a clear and unobstructed reagent delivery path, reduce the risk of blockage, and reduce the difficulty of equipment maintenance, thereby improving the uniformity and stability of reagent delivery.

[0032] Further, see attached document. Figures 4 to 8As shown, the anti-clogging mechanism includes a fixed plate 14 fixedly connected to the middle part of the mounting plate 8.

Sliding plates 16 are slidably connected to both the side wall of the fixed plate 14 and the side wall near the limiting plates 15. A compression spring 23 is fixedly connected to the inner wall of one end of the fixed plate 14. A limiting push plate 17 is rotatably connected to the side wall of the sliding plate 16 away from the compression spring 23. A compression plate 18 is fixedly connected to one end of the limiting push plate 17. Multiple evenly distributed contact blocks 1 are fixedly connected to the side wall of the limiting push plate 17 near the sliding plate 16. 9. The sidewalls of the contact block 19 are in contact with the sidewalls of the sliding plate 16. One end of the compression spring 23 is fixedly connected to the sliding plate 16 near the compression plate 18. A concave block 20 is fixedly connected to the sidewall of the limiting push plate 17. The inner wall of the concave block 20 is adapted to the outer wall of the sliding plate 16. A magnet 21 is fixedly connected inside the concave block 20. An iron block 22 is fixedly connected to the sidewall of the sliding plate 16 near the compression spring 23. The magnet 21 and the iron block 22 are in contact. A communication port 24 is opened on the sidewall of the monitoring box 1 near the compression plate 18. One side of the monitoring box 1... A toothed plate 25 is slidably connected to the side wall near the connecting port 24. One end of the toothed plate 25 is arc-shaped. The side wall of the pressing plate 18 contacts one end of the toothed plate 25. A return spring 37 is fixedly connected to the side wall of the toothed plate 25. One end of the return spring 37 is fixedly connected to the side wall of the monitoring box 1. A gear 26 meshes with the top of the toothed plate 25. The gear 26 is rotatably connected to the side wall of the monitoring box 1. A planetary gear 27 is fixedly connected to one end of the shaft of the gear 26. A rotating block 28 is rotatably connected to the side wall of the monitoring box 1 near the top of the planetary gear 27. A connecting rod 29 is fixedly connected to the side wall of the rotating block 28. A groove 30 is provided inside one end of the connecting rod 29. A retraction spring 31 is fixedly connected to the inner wall of the groove 30. A contact rod 32 is fixedly connected to one end of the retraction spring 31. One end of the contact rod 32 is slidably connected in the groove 30. The side wall of the contact rod 32 is in contact with the outer wall of the planetary gear 27. A hammer 33 is fixedly connected to the side wall of the rotating block 28. A bell 34 is fixedly connected to the side wall of the monitoring box 1 near the side wall of the hammer 33. The hammer 33 is in contact with the bell 34. The hammer 33 is tilted towards the bell 34 and the weight of the hammer 33 is greater than the weight of one end of the connecting rod 29.

[0033] When the anti-clogging mechanism is in use, firstly, the flexible expansion bladder 7 on the delivery pipe 6 is placed between the limiting plate 15 and the sliding plate 16. The flexible expansion bladder 7 is positioned between the limiting plate 15 and the sliding plate 16 and is in contact with the inner walls of the limiting plate 15 and the sliding plate 16. Then, the limiting push plate 17 is rotated, causing the concave block 20 to rotate. Subsequently, the concave block 20 comes into contact with the outer wall of the sliding plate 16 near the side wall of the compression spring 23. At this time, the magnet 21 is attracted to the outer wall of the iron block 22, thereby limiting the limiting push plate 17. When the delivery pipe 6 is blocked and the water flow is obstructed, the pressure inside the delivery pipe 6 increases significantly, and the water flow is forced forward. The increase in pressure pushes the water flow into... The water enters the flexible expansion bladder 7, and its volume expands as the amount of water increases. When the bladder expands, it pushes the limiting plate 15, which in turn pushes the contact block 19. The contact block 19 then pushes the limiting push plate 17 to move. As the limiting push plate 17 moves, it pushes the sliding plate 16 through the concave block 20 to compress the compression spring 23. At this time, the limiting push plate 17 also pushes the compression plate 18 to move and compress the toothed plate 25. When the toothed plate 25 is compressed, it slides towards the return spring 37 and compresses it. Then, the toothed plate 25 meshes with the gear 26, causing the gear 26 to rotate. When the gear 26 rotates, it drives the planetary gear 27 to rotate. As the planetary gear 27 rotates... The planetary gear 27 pushes the contact rod 32 through its outer wall shape. The contact rod 32, when pushed, causes the connecting rod 29 to rotate, which in turn causes the rotating block 28 to rotate. When the rotating block 28 rotates, it lifts and causes the striking hammer 33 to rotate. When the outer wall teeth of the planetary gear 27 are not in contact with the contact rod 32, the striking hammer 33, under the influence of gravity, will strike the outer edge of the bell 34, thus making a sound to alert staff to quickly clear the delivery pipe 6. In the anti-blockage mechanism, the flexible expansion bladder 7 expands and pushes the limiting plate 15. The limiting plate 15 further pushes the contact block 19, which in turn pushes the limiting push plate 17 to move. The limiting push plate 17 pushes the toothed plate 2 through the squeezing plate 18. 5. This causes the hammer 33 to strike the bell 34, enabling the anti-blocking mechanism to monitor the flow status of the delivery pipe 6 in real time, promptly detect blockages, and issue warnings. This solves the problem that due to the large number and complex arrangement of the delivery pipes 6, and the presence of impurities in the liquid, blockages or blockages can easily occur after prolonged use, leading to insufficient or complete stagnation of reagent flow, thus affecting the accuracy and timeliness of water quality testing and further impacting the stable operation of the instrument. It achieves active monitoring and fault indication of the delivery pipe 6, allowing staff to quickly handle blocked delivery pipes 6, avoiding the impact of reagent delivery stagnation on the monitoring process, and significantly improving the stability and ease of maintenance of the equipment.

[0034] Further, see attached document. Figure 3As shown, rollers 35 are rotatably connected to one side of the arc-shaped clamp 11. The rollers 35 reduce the friction when the outer wall of the conveying pipe 6 presses against the side wall of the arc-shaped clamp 11.

[0035] Further, see attached document. Figure 3 As shown, multiple evenly distributed label slots 36 are fixedly connected to the side wall of the mounting plate 8 near the bottom of the arc-shaped clamp 11. The label slots 36 serve to place label paper, making it easier to distinguish which reagent bottle 4 the delivery tube 6 is connected to.

[0036] Further, see attached document. Figure 7 As shown, the contact rod 32 is V-shaped. Due to the shape of the contact rod 32, when the pressing plate 18 is not in contact with the toothed plate 25, the return spring 37 will release the spring force to push the toothed plate 25 to slide towards the connecting port 24. At this time, the toothed plate 25 will drive the planetary gear 27 to rotate. When the planetary gear 27 rotates, it will press the contact rod 32, and the contact rod 32 will extend and retract into the groove 30 so that it does not obstruct the rotation of the planetary gear 27.
