[0001] This invention relates to the field of water quality testing equipment technology, specifically to a multi-parameter online water quality monitoring instrument for wastewater discharge. Background Technology

[0002] With increasing environmental awareness and rising demands for water resource management, wastewater discharge quality monitoring has become a crucial aspect of environmental protection. The complex and variable composition of wastewater places higher demands on water quality monitoring. To ensure wastewater discharge meets standards and protect water resources and the environment, water quality monitoring technologies are continuously evolving, striving for accurate and comprehensive monitoring.

[0003] Traditional devices have the following shortcomings: Currently, traditional wastewater discharge water quality monitoring instruments mostly use a single sampling point for monitoring. These instruments are usually fixed in a specific location, and the sampling depth is also relatively fixed. Because the composition of wastewater is affected by various factors, such as its source and treatment process, the monitoring results from a single location often fail to accurately reflect the overall water quality. Therefore, limited sampling capacity and insufficient sample size lead to questions about the reliability and accuracy of the monitoring results from commonly used wastewater discharge water quality monitoring instruments, making it difficult to meet the actual monitoring needs of current wastewater discharge processes.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0018] Please see Figure 1-6 As shown, this invention provides a technical solution for a multi-parameter online water quality monitoring instrument for wastewater discharge: A multi-parameter online water quality monitoring instrument for wastewater discharge includes a mounting plate 1. A liquid pump 2 is fixedly mounted on the upper end of the mounting plate 1. The input end of the liquid pump 2 is connected to a mixing component 3 for mixing wastewater samples. A sampling component 4 is mounted on the end of the mixing component 3. The output end of the liquid pump 2 is connected to a drain pipe 5. A detection part 6 is mounted on the wall of the drain pipe 5. The sampling component 4 includes a positioning seat 401, an adjusting pipe 403, a rotating component 406, and a liquid sampling hose 407. The positioning seat 401 is fixedly mounted on the lower side of the end of the mixing component 3, and a pressure cap 402 is threadedly connected to the outer side of the positioning seat 401. One end of the adjusting pipe 403 is movably connected to the end of the pressure cap 402 via a mounting protrusion ring. The other end of the adjusting pipe 403 is rotatably connected to an inner sleeve 404, and an outer sleeve 405 is movably connected to the end of the inner sleeve 404 away from the adjusting pipe 403. Rotating assembly 406 is movably mounted at both ends of inner sleeve 404. Adjusting tube 403 and outer sleeve 405 are both rotatably connected to inner sleeve 404 via rotating assembly 406. Liquid inlet of liquid collection hose 407 is mounted at end of outer sleeve 405, and liquid outlet of liquid collection hose 407 passes through outer sleeve 405, inner sleeve 404 and adjusting tube 403 and is connected to positioning seat 401.

[0019] The length of the liquid extraction hose 407 is greater than the sum of the lengths of the positioning seat 401, the adjusting tube 403, the inner sleeve 404, and the outer sleeve 405. The liquid extraction hose 407 is bent and laid inside the inner sleeve 404 and the outer sleeve 405 to form a length redundancy for easy rotation.

[0020] When the device needs to take samples, first rotate the cap 402 to loosen the adjusting tube 403 from the positioning seat 401. Then, using the axis of the positioning seat 401 and the adjusting tube 403 as the center, rotate the inner sleeve 404 to adjust the angle between the positioning seat 401 and the adjusting tube 403. Note that the rotation angle is ±180 degrees to avoid the liquid collection hose 407 from getting tangled with the rotating component 406. After adjustment, rotate the cap 402 in the opposite direction to tighten the ends of the adjusting tube 403 and the positioning seat 401 to restore the positioning. Then, by rotating the component 406, adjust the angles between the inner sleeve 404 and the adjusting tube 403, as well as between the inner sleeve 404 and the outer sleeve 405. By adjusting the relative positions and angles of the inner sleeve 404, the outer sleeve 405, and the adjusting tube 403, the distance between the port of the liquid collection hose 407 and the mixing component 3 can be adjusted. Finally, fix the mounting plate 1 on both sides of the pool so that the monitor is above the sewage surface. At this time, start the liquid pump 2 to begin sampling.

[0021] The sampling component 4, with its multiple adjustable sampling arms, enables flexible sampling at multiple points and depths within the wastewater tank. The increased sample capacity significantly improves the accuracy and reliability of water quality monitoring. Compared to traditional monitoring instruments, it can capture water quality information in the wastewater tank more comprehensively, effectively avoiding the biased results caused by monitoring at a single location, and providing a strong basis for water quality assessment and management.

[0022] The mixing assembly 3 includes a mixing tube 301, a connecting cover 304, and a filter plate 305. The mixing tube 301 is connected to the input end of the liquid pump 2. Positioning plates 302 are fixedly installed on both sides inside the mixing tube 301, and the positioning plates 302 include several drainage holes for sample flow. A spiral mixer 303 is horizontally connected between the positioning plates 302. The connecting cover 304 is installed at the end of the mixing tube 301. The lower side of the connecting cover 304 is arc-shaped, and a positioning seat 401 is fixedly installed on the arc surface of the connecting cover 304. The outlet end of the liquid collection hose 407 extends through the positioning seat 401 into the connecting cover 304. The filter plate 305 is movably installed in a slot at one end of the mixing tube 301 to filter solid impurities in the wastewater sample. A sealing strip is provided between the filter plate 305 and the slot opening to ensure the sealing of the mixing tube 301 and the connecting cover 304.

[0023] When the liquid pump 2 is turned on, a negative pressure is generated in the mixing pipe 301 and the connecting cover 304. Sewage is drawn in from the end of the liquid collection hose 407 and enters the connecting cover 304. After being filtered by the filter plate 305, it enters the spiral mixer 303. During the movement of the sewage in the spiral mixer 303, it is further mixed evenly. Finally, it passes through the liquid pump 2, fills the drain pipe 5, and is discharged upward. The water quality is monitored in real time by the sensor installed on the detection part 6 on the drain pipe 5.

[0024] The mixing component 3 enables multiple wastewater samples to be thoroughly filtered and mixed before water quality monitoring, avoiding interference from solid impurities on the measurement performance of optical sensors and the calculation of other water quality parameters. In addition, the thorough mixing with the spiral mixer 303 further improves the accuracy and reliability of the monitoring results.

[0025] The detection unit 6 includes a through hole 601 and a mounting tube 604. The through hole 601 is vertically formed on one side of the drain pipe 5. A base 602 is mounted on the outer side of the through hole 601 on the wall of the drain pipe 5. The base 602 has several threaded holes 603 corresponding to the through hole 601. The mounting tube 604 is threaded into the threaded holes 603 and its end is located inside the drain pipe 5. In practical applications, the mounting tube 604 is used to install a sensor for monitoring water quality. When sewage flows through the reading area at the end of the mounting tube 604, the internal sensor monitors and reads data in real time. Since the drain pipe 5 is vertically installed and the detection unit 6 is located in the vertical section of the drain pipe 5, the end of the mounting tube 604 can always be immersed in the sample.

[0026] The detection unit 6 enables the sensor acquisition end to successfully collect and monitor data from the sample. Furthermore, installing the base 602 on the vertical section of the drain pipe 5 ensures that the sensor acquisition end is always submerged in the sample, preventing air intrusion and ensuring accurate data reading.

[0027] Rotating assembly 406 includes: Adjusting shaft 4061 is rotatably connected to both ends of inner sleeve 404. The ends of adjusting tube 403 and outer sleeve 405 are rotatably connected to adjusting shaft 4061 through holes. Pressure ring 4062 is slidably connected in a groove on the inner wall of inner sleeve 404, located at one end of adjusting shaft 4061. Pressure ring 4062 is threadedly connected to adjusting shaft 4061. By rotating adjusting shaft 4061, the position of pressure ring 4062 can be adjusted, thereby adjusting the pressure applied by pressure ring 4062 to adjusting tube 403 and outer sleeve 405. The gear 4063 is installed on the inner wall at both ends of the inner sleeve 404, located outside the adjusting shaft 4061. The ends of the adjusting tube 403 and the outer sleeve 405 are provided with tooth grooves that match the gear 4063.

[0028] When it is necessary to adjust the angle between the inner sleeve 404, the outer sleeve 405, and the adjusting tube 403, first rotate the adjusting shaft 4061 to retract the pressure ring 4062 into the groove of the inner sleeve 404. Do not apply pressure to the adjusting tube 403 and the outer sleeve 405. The geared discs 4063 at both ends of the inner sleeve 404 separate from the toothed grooves at the ends of the adjusting tube 403 and the outer sleeve 405. At this time, the adjusting tube 403 and the outer sleeve 405 can rotate around the inner sleeve 404 with the adjusting shaft 4061 as the axis. After rotating to the appropriate angle, rotate the adjusting shaft 4061 in the opposite direction to re-engage the adjusting tube 403 and the outer sleeve 405, until the geared discs 4063 are again embedded in the toothed grooves at the ends of the adjusting tube 403 and the outer sleeve 405. At this point, both the adjusting tube 403 and the outer sleeve 405 are properly positioned with the inner sleeve 404.

[0029] By rotating component 406, the angle between adjusting tube 403 and outer sleeve 405 and inner sleeve 404 can be adjusted and locked. The operation is simple and convenient, and the flexibility of the monitor in selecting sampling points and depths is improved.

[0030] The end of the adjusting shaft 4061 is provided with an internal hexagonal groove, which allows the user to easily rotate and adjust the adjusting shaft 4061 using a hexagonal wrench.

[0031] Both the inner sleeve 404 and the outer sleeve 405 are provided with drainage holes 7. Since the inner sleeve 404 and the outer sleeve 405 adopt a non-sealed design, the drainage holes 7 can facilitate the rapid discharge of residual wastewater from the inner sleeve 404 and the outer sleeve 405 after the monitoring instrument leaves the sewage tank.

[0032] Several plugs 605 for sealing are also threaded into the threaded hole 603. Due to different monitoring requirements, not every threaded hole 603 has an installation tube 604. In this case, the empty threaded hole 603 can be sealed with plugs 605 to prevent sewage from overflowing.

[0033] Working principle: When the device needs to take samples, first rotate the pressure cap 402 to loosen the adjusting tube 403 from the positioning seat 401. Then, using the axis of the positioning seat 401 and the adjusting tube 403 as the center, rotate the inner sleeve 404 to adjust the angle between the positioning seat 401 and the adjusting tube 403. After adjustment, rotate the pressure cap 402 in the opposite direction to tighten the ends of the adjusting tube 403 and the positioning seat 401 to restore the positioning. Then, rotate the adjusting shaft 4061 to adjust the angle between the inner sleeve 404 and the adjusting tube 403, as well as between the inner sleeve 404 and the outer sleeve 405. This achieves the purpose of adjusting the sampling point and depth. Finally, fix the mounting plate 1 on both sides of the pool so that the monitor is positioned above the sewage surface. At this time, the liquid pump 2 is started, and negative pressure is generated in the mixing pipe 301 and the connecting cover 304. The sewage is sucked in from the end of the liquid collection hose 407 and enters the connecting cover 304. Then, after being filtered by the filter plate 305, it enters the spiral mixer 303. During the movement of the sewage in the spiral mixer 303, it is further mixed evenly. Finally, it passes through the liquid pump 2, fills the drain pipe 5, and is discharged upward. The data reading area of ​​the installation pipe 604 is submerged in the sample sewage, which can be used for real-time monitoring and data acquisition.
