Description

Technical Field

[0001] This invention relates to the field of wastewater monitoring equipment, and more specifically, to a device for monitoring the quality and quantity of wastewater in pipelines. Background Technology

[0002] The sewage pipeline system consists of pipes and ancillary structures that collect and transport urban sewage. Sewage flows from branch pipes into main pipes, then into the main trunk, and finally into the sewage treatment plant. The pipes grow from small to large, distributed like a river in a tree-like pattern, which is completely different from the circulation of water supply networks. Sewage generally flows from high to low in the pipes due to the difference in water level at both ends. The pipes do not bear pressure, so they flow by gravity. The sewage in the pipes contains a certain amount of organic and inorganic matter. The less dense matter floats on the surface and drifts with the sewage, while the heavier matter is distributed across the water flow cross-section and flows in a suspended state. The heaviest matter moves along the bottom of the pipe or accumulates on the pipe wall. This situation is slightly different from the flow of clean water. Currently, people use water quality monitoring devices to monitor the sewage quality in the sewage pipelines, allowing sewage treatment plants to obtain relevant information about the sewage in advance and adjust their sewage treatment plans accordingly. It can also provide data for the analysis of urban pollution.

[0003] Existing sewage pipeline water quality monitoring devices mainly consist of sewage detectors and detection probes. The detection probes are fixedly inserted into the sewage pipeline along its diameter. However, large-diameter sewage pipelines are not always full, and the internal liquid level is not constant. Affected by the sewage flow, the internal liquid level sometimes rises and sometimes falls, which may cause the detection probe to separate from the sewage in the pipeline, resulting in the interruption of sewage monitoring. At the same time, the fixedly installed detection probes can only perform a rough detection of the sewage in the pipeline and cannot perform layer-by-layer detection of the sewage in the pipeline, resulting in a large error in the detection results. Therefore, there is an urgent need to design a sewage pipeline water quality and quantity monitoring device. Summary of the Invention

[0005] Existing sewage pipeline water quality monitoring devices mainly consist of a sewage detector and a detection probe. The detection probe is fixedly inserted into the sewage pipeline along its diameter. However, large-diameter sewage pipelines are not always full, and the internal liquid level is not constant. Affected by the sewage flow, the internal liquid level sometimes rises and sometimes falls, which may cause the detection probe to separate from the sewage in the pipeline, resulting in the interruption of sewage monitoring. At the same time, the fixedly installed detection probe can only perform a rough detection of the sewage in the pipeline and cannot perform layer-by-layer detection of the sewage in the pipeline, resulting in large errors in the detection results.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of this invention are:

[0017] The online wastewater monitoring system can monitor the liquid level and flow rate of dynamically flowing wastewater within the pipeline. It automatically presets a maximum current value based on the wastewater level. A wastewater sampling device allows the system to lift and detect the dynamically flowing wastewater within the pipeline. A reciprocating mechanism allows the sampling device to move slowly up and down, changing the water layer at which the sample is taken, achieving layer-by-layer detection. This results in high accuracy and representativeness. A continuous flow device can also be used to change the position of the wastewater sampling device. The outlet allows the collected water sample to rise smoothly. A plugging device not only resets the continuous water supply device but also removes any blockages from the wastewater sampling component, preventing it from becoming clogged. A position monitoring mechanism tracks the location of the wastewater sampling component, allowing the online wastewater monitoring system to limit its upward and downward displacement based on preset maximum and minimum values. This ensures the bottom of the sampling component doesn't separate from the dynamically flowing wastewater, guaranteeing uninterrupted monitoring and improving the practicality of the wastewater pipeline water quality and quantity monitoring device.

[0038] Working principle:

[0039] First, the open channel flow meter 205 detects the liquid level of the dynamically flowing sewage 12 in real time. Then, the open channel flow meter 205 sends the detected liquid level value to the intelligent power distribution control box 207 in real time. Next, the intelligent power distribution control box 207 generates a real-time maximum current value based on the real-time liquid level value. Then, the intelligent power distribution control box 207 controls the operation of the sewage sampling pump 208 and the online sewage detector 210. Then, the sewage sampling pump 208 draws sewage from the water sample lift pipe 38 and pumps it into the online sewage detector 210 through the water sample delivery pipe 209. Then, the online sewage detector 210 performs real-time monitoring of the sewage. After the sewage has been monitored, it is discharged into the sewage transport pipeline 11 through the sewage return pipe 211 and flows into the dynamically flowing sewage 12. At the same time... The hydraulic pressure inside the water sample lift tube 38 decreases relatively, and then the hydraulic pressure inside the sewage sampling chamber 32 decreases synchronously. Next, the hydraulic pressure inside the sampling thick-walled tube 37 is greater than that inside the sewage sampling chamber 32. Subsequently, the corresponding conical plug 42 moves outward under the action of the hydraulic pressure difference. Then, the inner wall of the cylindrical cavity 44 applies pressure to the compression spring 45, causing the compression spring 45 to compress elastically and increase its elastic potential energy. This increases the gap between the conical plug 42 and the inner wall of the water-passing cone hole 41. Then, the sewage inside the sampling thick-walled tube 37 enters the water sample lift tube 38 through the water-passing cone hole 41 and the sewage sampling chamber 32. Thus, the dynamically flowing sewage 12, under the action of the sewage sampling pump 208, flows along the sampling thick-walled tube 37, the corresponding water-passing cone hole 41, the sewage sampling chamber 32, and the water sample lift tube 38. The sewage pipe 38, sewage sampling pump 208, water sample delivery pipe 209, sewage online detector 210, and sewage return pipe 211 flow. Then, the intelligent power distribution control box 207 controls the operation of the lifting servo motor 71. After that, the lifting servo motor 71 drives the lifting wheel 72 to rotate. Then, the lifting line 73 winds around the outside of the lifting wheel 72 and moves the sampling thick-walled tube 37 upward through the lifting column 74. Then, the bottom end of the sampling thick-walled tube 37 moves upward inside the dynamically flowing sewage 12, thereby continuously changing the water sampling layer, which can monitor the water quality of different water layers and has better representativeness. Then, the sampling thick-walled tube 37 moves upward with the water passage cone 41. Then, the uppermost open water passage cone 41 slides onto the surface of the sealing piston column 62. Then, the water passage cone 41... When the small port of 1 is blocked, the conical plug 42 moves to the left under the force of the compression spring 45, squeezing out the sewage inside the water-passing cone hole 41. Then, the conical plug 42 re-blocks the water-passing cone hole 41. Simultaneously, the water-passing cone hole 41 adjacent to the sewage sampling column 31 enters the sewage sampling chamber 32 and is connected under the action of hydraulic pressure difference. Then, the sampling thick-walled tube 37 moves upward with the linkage extension bar 57. The linkage extension bar 57 then moves upward with the V-shaped elastic conductive sheet 56 via the insulating reciprocating block 54. Next, the end of the V-shaped elastic conductive sheet 56 slides upward on the surface of the strip resistor bar 53. Then, the length of the strip resistor bar 53 connected to the circuit gradually shortens, and the current through the strip resistor bar 53 increases.When the current reaches the preset maximum value inside the intelligent power distribution control box 207, the intelligent power distribution control box 207 controls the lifting servo motor 71 to stop running. At this time, the bottom end of the sampling thick-walled tube 37 is displaced to the highest point in the dynamically flowing sewage 12, thus completing one detection. Then, the intelligent power distribution control box 207 controls the sewage sampling pump 208 and the sewage online detector 210 to stop. After that, the intelligent power distribution control box 207 controls the electric telescopic cylinder 61 to extend. Then, the electric telescopic cylinder 61, along with the sealing piston 62, moves downward relative to the sampling thick-walled tube 37. Then, the sealing piston 62 pushes the foreign objects intercepted on the inner wall of the sampling thick-walled tube 37 downward. Then, the sealing piston 62 pushes the foreign object out of the sampling thick-walled tube 37. Next, the intelligent power distribution control box 207 controls the electric telescopic cylinder 61 to shorten to its shortest position. At this point, the sealing piston 62 resets. Then, under the action of the return spring 76, the lifting ring 75 moves downwards along the lifting column 74, carrying the sampling thick-walled tube 37, until the current through the strip resistor 53 reaches the preset minimum value inside the intelligent power distribution control box 207. Afterwards, the intelligent power distribution control box 207 controls the sewage sampling pump 208 and the online sewage detector 210 to run again, starting a new round of detection. This process is repeated to monitor the dynamically flowing sewage 12.
