Description

Technical Field

[0001] This invention belongs to the field of environmental monitoring technology, and in particular relates to an automatic monitoring and analysis device for water and sediment concentration and multiple water quality indicators in the canal system of southern Xinjiang. Background Technology

[0002] Southern Xinjiang is a typical desert oasis irrigated agricultural area. Water resources mainly come from glacial meltwater and mountain rainfall. During the flood season, water is introduced into oasis reservoirs for spring irrigation, or directly irrigated farmland during the growing season, including winter irrigation. With the improvement of living standards and the high level of industrialization, the discharge of various kinds of garbage and sewage is also increasing. Therefore, people are paying more and more attention to environmental governance. Environmental governance first requires environmental testing, including sewage testing. Before testing, it is necessary to collect microorganisms in the water at different depths.

[0003] Existing technology discloses a wastewater collection device for water environment monitoring (publication number CN112834285B). The device consists of a submersible chamber as the main body, on which a drive unit is installed. Multiple shell units are mounted circumferentially along the axis of the drive unit. These shell units are connected to the submersible chamber via connecting rods, which are hinged to both the chamber and the shell units. The drive unit can drive the shell units to close and open axially. When fully closed, a sealed space is formed between the shell units to accommodate the water sample. During operation, the device first submerges below the water surface to the desired depth for sampling, maintaining a stable suspended state. Once stable, the drive unit activates, causing the shell units to close. The surrounding shell units converge towards the center, sealing adjacent units together. The closed shell units form a sealed space. During the closing process, the suspension is stable, water sample disturbance is minimal, and water sample integrity is maintained. However, in implementing this technical solution, at least the following problems were found in the existing technology: Overall, the oasis irrigation area in southern Xinjiang has a closed topography, weak horizontal runoff of groundwater, and soluble salts are not easily transported and mostly remain in place. In addition, the reservoir supports the shallow groundwater and the large amount of irrigation water during the irrigation season and winter irrigation cause the groundwater level to remain within a certain range for a long time with very small fluctuations. The drainage system stores saline water, causing the groundwater level in the fields to periodically exceed the critical depth. The regional groundwater level is continuously at the level of the drainage canals, and the decline in water level is mainly due to traditional vertical evaporation. With a drought index exceeding 30, the vertical transport of water and salt in the soil is active due to the infiltration of irrigation water and strong evaporation. This results in frequent seasonal dissolution and leaching of salt and alkali in farmland, causing periodic salt return to the soil. Year after year, this forms the modern salt accumulation process in the topsoil of irrigated areas. When researchers attempt to obtain water samples from a specific depth, the sampling equipment inevitably enters water at other depths, resulting in the collected water samples not fully representing the water quality at the target depth. This cross-contamination leads to deviations in the test results and affects the accuracy of the data. In addition, water samples often contain suspended particles such as silt, which can easily interfere with the equipment and affect the reliability of the test results. Especially when sampling rivers, the presence of aquatic plants and floating objects is a thorny issue. Because these substances are difficult to filter effectively, they can cause blockages or even damage to the equipment. Summary of the Invention

[0015] This invention provides an automatic monitoring and analysis device for multiple water quality indicators, including sediment concentration and water quality, in the Southern Xinjiang Canal System. The automatic monitoring and analysis device for water and sediment concentration and multiple water quality indicators in the Southern Xinjiang Canal System first fixes one end of a rope to a steel rope connecting ring. The device is then deployed to the water area to be tested. When the drive motor drives the rotating rod to rotate counterclockwise, the rotating rod drives the active bevel gear to rotate, which in turn drives the driven bevel gear and the rotating rod to rotate. The rotating rod drives the propeller to rotate, and the propeller draws water through the filter inlet pipe into the suction cylinder, increasing the device's gravity. Excess water is discharged from the drain pipe. The propulsive force generated by the discharged water flow accelerates the device's settling speed, allowing it to quickly reach the predetermined testing area. This not only significantly shortens the sampling time but also greatly improves work efficiency.

[0016] The automatic monitoring and analysis device for water and sediment concentration and multiple water quality indicators in the Southern Xinjiang Canal System operates as follows: Before reaching the test area, the rotating rod rotates counterclockwise, causing the double-ended gravity ball rod to move in the top straight groove of the guide channel, keeping the sealing mechanism in a sealed state. When the test area is reached, the drive motor drives the rotating rod to rotate clockwise, which in turn drives the limiting column to rotate. As the double-ended gravity ball rod passes above the inclined groove of the guide channel, it falls into the inclined groove of the guide channel due to the weight of its ends, causing the guide channel to push one end of the double-ended gravity ball rod to move. The water sample enters the bottom straight groove of the guide groove, causing the double-ended gravity ball rod to pull the connecting plate through the hollow ball. The connecting plate drives the rotating ring to rotate, and the rotating ring pulls the push-pull rod through the hinge seat. This causes the push-pull rod to pull the sealing plate through the hinge rod. The sealing plate moves around the shaft rod, thus opening the sealing mechanism. This ensures that only water samples at the target depth enter the suction cylinder, preventing water samples at other depths from entering the suction cylinder and causing cross-contamination, which would lead to deviations in the test results and affect the accuracy of the data.

[0017] The rotating rod drives the inclined circular plate to rotate, and the inclined circular plate pushes and pulls the lifting hollow tube in a reciprocating lifting motion. Because the friction between the piston and the connecting bracket is greater than the friction between the piston and the lifting hollow tube, when the lifting hollow tube drives the lifting cylinder to rise, the piston of the lifting hollow tube does not move. The lifting cylinder needs to pull the piston to move. When the piston contacts the lifting cylinder, the piston blocks the water suction hole, creating a negative pressure at the bottom of the piston. The blocking ball releases the seal on the sealing port, allowing water to enter the water suction cylinder from the sealing port. When the lifting hollow tube drives the lower pressure ring to descend, the lower pressure ring pushes... As the piston descends, the suction port is exposed, and the blocking ball seals the port during its descent. This minimizes disturbance to the water sample, enhancing the integrity of the sample. After sealing, the piston squeezes the water inside the suction cylinder, and the squeezed water enters the lifting hollow tube through the suction port and flows into the U-shaped connecting tube, thus allowing the water to enter the sampling bottle and achieve water sample collection. This design not only improves sampling efficiency but also ensures the accuracy and reliability of the sampling process.

[0018] During water absorption, impurities in the water are filtered by the filter cartridge and adsorbed onto the cartridge. The rotating rod drives the pressure block to rotate, pushing one end of the lifting rod downwards and raising the other end. When the pressure block is not in contact with the lifting rod, the impact ball falls under its own weight, impacting the filter cartridge and causing it to vibrate. This facilitates the effective removal of impurities adhering to the filter cartridge, preventing solid impurities from accumulating on the cartridge, extending the maintenance cycle of the device, and reducing maintenance costs. The rotating rod also drives the L-shaped scraper to rotate, which adheres tightly to the filter cartridge, resulting in better cleaning. This not only extends the service life of the equipment but also reduces the labor and material costs during maintenance. Additionally, a cutting blade is installed at the bottom of the rotating rod, which can be rotated by the rod to effectively cut and separate aquatic plants in the water. This prevents these plants from interfering with or obstructing the device's movement and submersion operations. Furthermore, cutting aquatic plants prevents them from tangling in the water, ensuring smooth operation of the device and improving work efficiency and safety. Attached Figure Description

An inclined circular plate 23 is fixedly connected to the outer wall of the rotating rod 202. A slot 24 is opened on the outer wall of the lifting hollow tube 203. The inner wall of the slot 24 is in contact with the outer wall of the inclined circular plate 23. This arrangement is so that the rotating rod 202 drives the inclined circular plate 23 to rotate. The inclined circular plate 23 pushes and pulls the lifting hollow tube 203 through the slot 24 to perform reciprocating lifting and lowering movements.

[0028] A water suction mechanism 3 is provided on the outer wall of the lifting hollow tube 203.

A piston 304 is provided between the pressure ring 302 and the lifting cylinder 303. The outer wall of the piston 304 is slidably connected to the inner wall of the water suction cylinder 204. The inner wall of the piston 304 is connected to the lifting cylinder 204. The outer wall of the lowering hollow tube 203 is slidably connected.

[0029] like Figures 6 to 10As shown, a sealing mechanism 4 is provided at the bottom of the water suction cylinder 204. The sealing mechanism 4 includes a fixed circular plate 401 fixedly connected to the bottom of the water suction cylinder 204. A limiting slide rod 402 is fixedly connected to the bottom of the fixed circular plate 401. A rotating ring 403 is provided at the bottom of the fixed circular plate 401. An arc-shaped groove 404 is formed on the side wall of the rotating ring 403. The inner wall of the arc-shaped groove 404 is slidably connected to the outer wall of the limiting slide rod 402.

A shaft rod 409 is rotatably connected to the through hole of the sealing plate 408. One end of the shaft rod 409 is fixedly connected to the bottom of the fixed circular plate 401. This arrangement is so that the rotating ring 403 can move by pulling the push-pull rod 406 through the hinge seat 405, thereby causing the push-pull rod 406 to pull the sealing plate 408 through the hinge rod 407. The sealing plate 408 moves around the shaft rod 409 as the axis.

[0030] A sealing assembly 5 is provided on the outer wall of the rotating rod 202. The sealing assembly 5 includes a limiting post 501 fixedly connected to the outer wall of the rotating rod 202. A guide groove 502 is opened on the outer wall of the limiting post 501. A limiting cylinder 503 is fixedly connected to the outer wall of the limiting post 501. The groove on the limiting cylinder 503 is relatively smaller than the guide groove 502. This is to prevent one end of the double-ended gravity ball rod 504 from detaching from the guide groove 502. The double-ended gravity ball rod 504 is slidably connected to the inner wall of the guide groove 502. A hollow retaining ball 505 is rolledly connected to the end of the double-ended gravity ball rod 504 away from the guide groove 502. A connecting plate 506 is fixedly connected to the outer wall of the hollow retaining ball 505. The side wall of the connecting plate 506 is fixedly connected to the bottom of the rotating ring 403. When the double-ended gravity ball rod 504 is in the top straight groove of the guide groove 502, the sealing mechanism 4 is in a sealed state.

[0031] like Figure 11 and Figure 12As shown, a striking mechanism 6 is provided at the bottom of the connecting bracket 205. The striking mechanism 6 includes a water inlet cylinder 601 fixedly connected to the bottom of the connecting bracket 205, and a filter cylinder 602 fixedly connected to the bottom of the water inlet cylinder 601. This arrangement is for the filter cylinder 602 to filter impurities in the water. A hinge support 603 is fixedly connected to the inner wall of the filter cylinder 602, and a connecting rod 604 is fixedly connected to the side wall of the hinge support 603. A lifting rod 605 is rotatably connected to the outer wall of the connecting rod 604, and an impact ball 606 is fixedly connected to the side wall of the lifting rod 605. A pressure block 607 is fixedly connected to the outer wall of the rotating rod 202. This arrangement is for the rotating rod 202 to drive the pressure block 607 to rotate, and the pressure block 607 to push the lifting rod 602. One end of 05 descends, causing the other end of the lifting rod 605 to rise. When the pressure block 607 is not in contact with the lifting rod 605, the impact ball 606 descends under its own weight, thereby impacting the filter cylinder 602 and causing it to vibrate. An L-shaped scraper 608 is fixedly connected to the outer wall of the extension tube 22. This is designed so that the L-shaped scraper 608 can clean the outer surface of the filter cylinder 602. The outer wall of the L-shaped scraper 608 is in contact with the outer wall of the filter cylinder 602. A cutting blade 609 is fixedly connected to the bottom end of the extension tube 22. This is designed so that the cutting blade 609 can effectively cut and separate aquatic plants in the water. This can prevent these plants from interfering with or hindering the movement and diving operation of the device.

[0032] like Figure 13 and Figure 14As shown, due to the presence of air inside the sampling tube, this air will generate a certain buoyancy in the water. This buoyancy can easily cause the sampling tube to float on the surface of the water, making it inconvenient to collect water samples. An auxiliary lifting mechanism 7 is provided on the outer wall of the rotating rod 202. The auxiliary lifting mechanism 7 includes an active bevel gear 701 fixedly connected to the outer wall of the rotating rod 202. A fixed frame 702 is fixedly connected to the bottom of the counterweight circular plate 103. A rotating rod 703 is rotatably connected to the through hole of the fixed frame 702. A propeller 704 is fixedly connected to the outer wall of the rotating rod 703. A driven bevel gear 705 is fixedly connected to the end of the rotating rod 703. The side wall of the driven bevel gear 705 meshes with the side wall of the driving bevel gear 701. A suction cylinder 706 is fixedly connected to the side wall of the fixed frame 702. A filter water inlet pipe 71 is connected to the outer wall of the suction cylinder 706, and a drain pipe 72 is also connected to the outer wall of the suction cylinder 706. This arrangement ensures that when the drive motor 21 drives the rotating rod 202 to rotate counterclockwise, the rotating rod 202 drives the driving bevel gear 701 to rotate. The driving bevel gear 701 drives the driven bevel gear 705 and the rotating rod 703 to rotate. The rotating rod 703 drives the propeller 704 to rotate. The propeller 704 draws water through the filter inlet pipe 71 into the suction cylinder 706, increasing the weight of the device. Excess water is discharged from the drain pipe 72. The propulsive force generated by the discharged water flow accelerates the settling speed of the equipment, allowing it to quickly reach the predetermined testing area. This not only significantly shortens the sampling time but also significantly improves work efficiency. The top of the counterweight circular plate 103 is fixedly connected to... A connecting frame 73 is rotatably connected to a blocking plate 74 on its side wall. A connecting spring 75 is fixedly connected to the bottom of the blocking plate 74. The end of the connecting spring 75 away from the blocking plate 74 is fixedly connected to the top of the counterweight circular plate 103. This arrangement is such that when the drive motor 21 drives the rotating rod 202 to rotate clockwise, the drain pipe 72 generates suction, causing the connecting spring 75 to drive the blocking plate 74 to block the drain pipe 72, preventing water from entering from the drain pipe 72 and being discharged from the filter inlet pipe 71, thereby preventing the device from rising during the sampling process.

[0033] The working principle of an automatic monitoring and analysis device for water and sediment concentration and multiple water quality indicators in the canal system of southern Xinjiang: First, one end of the rope is fixed to the steel rope connecting ring 101. The device is then placed in the water area to be tested. When the drive motor 21 drives the rotating rod 202 to rotate counterclockwise, the rotating rod 202 drives the active bevel gear 701 to rotate. The active bevel gear 701 drives the driven bevel gear 705 and the rotating rod 703 to rotate. The rotating rod 703 drives the propeller 704 to rotate. The propeller 704 draws water through the filter inlet pipe 71 into the suction cylinder 706, increasing the weight of the device. Excess water is discharged from the drain pipe 72. The propulsion force generated by the discharged water flow accelerates the settling speed of the device, allowing it to quickly reach the predetermined testing area. In this way, the sampling time is greatly shortened, and the work efficiency is significantly improved. Before reaching the detection area, when the rotating rod 202 rotates counterclockwise, it moves the double-ended gravity ball rod 504 in the top straight groove of the guide groove 502, keeping the sealing mechanism 4 in a sealed state. When reaching the detection area, the drive motor 21 drives the rotating rod 202 to rotate clockwise, which in turn drives the limiting post 501 to rotate. When the double-ended gravity ball rod 504 passes above the inclined groove of the guide groove 502, it falls into the inclined groove of the guide groove 502 due to the weight of its ends. This causes the guide groove 502 to push one end of the double-ended gravity ball rod 504 into the bottom straight groove of the guide groove 502, thereby... The double-ended gravity ball rod 504 pulls the connecting plate 506 to move through the hollow ball 505. The connecting plate 506 drives the rotating ring 403 to rotate. The rotating ring 403 pulls the push-pull rod 406 to move through the hinge seat 405. This causes the push-pull rod 406 to pull the sealing plate 408 through the hinge rod 407. The sealing plate 408 moves around the axis rod 409, thereby opening the sealing mechanism 4. This ensures that only water samples at the target depth enter the suction cylinder 204, preventing water samples at other depths from entering the suction cylinder 204 and causing cross-contamination, which would lead to deviations in the test results and affect the accuracy of the data. The rotating rod 202 drives the inclined circular plate 23 to rotate, and the inclined circular plate 23 pushes and pulls the lifting hollow tube 203 to perform reciprocating lifting and lowering motion. Because the friction between the piston 304 and the connecting bracket 205 is greater than the friction between the piston 304 and the lifting hollow tube 203, when the lifting hollow tube 203 drives the lifting cylinder 303 to rise, the piston 304 does not move when the lifting hollow tube 203 rises. The lifting cylinder 303 needs to pull the piston 304 to move. When the piston 304 contacts the lifting cylinder 303, the piston 304 blocks the water suction hole 301, so that a negative pressure is generated at the bottom of the piston 304. The blocking ball 306 releases the blockage of the sealing port 307, allowing water to enter the water suction cylinder 204 from the sealing port 307. When the lifting hollow tube 202... When the lower pressure ring 302 descends, it pushes the piston 304 to descend, exposing the water suction hole 301. Meanwhile, the blocking ball 306 seals the sealing opening 307 during the descent, minimizing disturbance to the water sample and enhancing its integrity. After sealing, the piston 304 squeezes the water inside the suction cylinder 204. The squeezed water enters the lifting hollow tube 203 through the suction hole 301 and is discharged from the lifting hollow tube 203 into the U-shaped connecting tube 201, thus allowing the water to enter the sampling bottle 106 and achieve water sample collection. This design not only improves sampling efficiency but also ensures the accuracy and reliability of the sampling process. During the water absorption process, impurities in the water are filtered by the filter cartridge 602 and adsorbed onto the filter cartridge 602. The rotating rod 202 drives the pressure block 607 to rotate, and the pressure block 607 pushes one end of the lifting rod 605 down, causing the other end of the lifting rod 605 to rise. When the pressure block 607 is not in contact with the lifting rod 605, the impact ball 606 falls under its own weight, thereby impacting the filter cartridge 602 and causing it to vibrate. This facilitates the effective removal of impurities adhering to the filter cartridge 602, preventing solid impurities from accumulating on the filter cartridge 602, extending the maintenance cycle of the device, and reducing maintenance costs. The rotating rod 202 drives the L-shaped scraper 60... The L-shaped scraper 608 rotates and adheres tightly to the filter cartridge 602, resulting in better cleaning. This not only extends the service life of the equipment but also reduces the manpower and material costs during maintenance. Simultaneously, a cutting blade 609 is installed at the bottom of the rotating rod 202. The rotating rod 202 drives the cutting blade 609 to rotate, effectively cutting and separating aquatic plants in the water. This prevents these plants from interfering with or hindering the movement and submersion of the device. Furthermore, cutting aquatic plants prevents them from tangling in the water, ensuring smooth operation of the device and improving work efficiency and safety.
