[0020] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0021] Example 1: As Figures 1 to 9 shown, a layered extraction sampling device for online detection of filterable wastewater according to an embodiment of the present invention includes a main body 1 of a wastewater detection box. A box door 2 is rotatably installed on the front side of the main body 1 of the wastewater detection box. A control panel 3 is arranged at the upper end of the box door 2. A control module 4 is fixedly installed inside the upper end of the main body 1 of the wastewater detection box. A detection tank 5 is fixedly installed inside the main body 1 of the wastewater detection box. A plurality of detection chambers 6 are arranged inside the detection tank 5. A plurality of first connecting pipes 9 are fixedly installed on the lower side of the detection tank 5. A plurality of water pumps 10 are fixedly installed inside the right end of the main body 1 of the wastewater detection box. The plurality of first connecting pipes 9 are fixedly connected to the plurality of water pumps 10. A plurality of three-way joints 11 are fixedly installed inside the right end of the main body 1 of the wastewater detection box. The plurality of three-way joints 11 are fixedly connected to the plurality of water pumps 10. A cover plate 37 is movably installed on the left side of the lower end of the main body 1 of the wastewater detection box. A sample storage assembly is arranged inside the lower end of the main body 1 of the wastewater detection box.

[0022] In the actual operation process, the technical personnel in charge of the operation can control the plurality of water pumps 10 by operating the control module 4, so as to effectively extract the wastewater. These water pumps 10 are connected thereto through the plurality of first connecting pipes 9, enabling them to work together to smoothly pump the wastewater into the plurality of detection chambers 6. In addition, the plurality of three-way joints 11 are also connected to the water pumps 10, ensuring the smooth transportation and extraction of the wastewater. During the process of extracting the wastewater, through the carefully designed sample storage assembly, the extracted wastewater samples can be properly stored, which not only facilitates the subsequent reexamination of the wastewater but also provides the possibility for more in-depth analysis.

[0023] As Figures 1 to 3As shown, connection lines 7 are fixedly installed at the upper ends of multiple detection chambers 6. The multiple connection lines 7 are fixedly connected to the control module 4. At the lower ends of the multiple connection lines 7, detection heads 8 are fixedly installed, and the multiple detection heads 8 are respectively inserted into the multiple detection chambers 6 movably.

[0024] Through the multiple connection lines 7 and the multiple detection heads 8, the wastewater extracted and stored in the multiple detection chambers 6 is accurately detected. Moreover, through the collaborative work of the multiple detection heads 8, the comprehensiveness and accuracy of the detection are ensured. Each of the multiple detection heads 8 can independently analyze the wastewater samples in detail, thus ensuring the high precision of the detection results. In addition, the use of the multiple connection lines 7 enables the control module 4 to communicate with the multiple detection heads 8, further improving the detection efficiency. Through the systematic detection method, not only the detection precision is improved, but also the time required for detection is greatly shortened, thereby improving the overall detection efficiency.

[0025] As Figures 1 to 7 shown, water extraction pipes 12 are fixedly installed at the right - hand openings of multiple three - way connectors 11. At the lower ends of the multiple water extraction pipes 12, water extraction heads 13 are fixedly installed.

[0026] By setting multiple water extraction pipes 12, the multiple water extraction heads 13 can be inserted into wastewaters at different depths, thereby achieving comprehensive coverage and extraction of the wastewater. The water extraction heads 13 are not only for extracting wastewater. The surface of the water extraction heads 13 can conduct preliminary filtration treatment on the extracted wastewater, and then can effectively remove various impurities and particulate matters in the wastewater, thus ensuring the purity of the wastewater during extraction. This not only improves the efficiency of wastewater detection but also ensures the accuracy and reliability of the detection results.

[0027] As Figures 1 to 7 shown, the multiple water extraction pipes 12 are all made of thermoplastic rubber, and the inner walls of the multiple water extraction pipes 12 are all composed of steel wire spiral winding.

[0028] Based on the fact that the multiple water extraction pipes 12 are all made of thermoplastic rubber, they have excellent elasticity and sealing performance, which can ensure that there is no leakage during wastewater extraction. At the same time, the inner walls of the multiple water extraction pipes 12 are all composed of steel wire spiral winding, which improves the structural strength and service life of the multiple water extraction pipes 12.

[0029] As Figures 1 to 9As shown in the figure, the sample storage component includes multiple groups of solenoid valves 14. The multiple groups of solenoid valves 14 are fixedly installed at the left ends of multiple groups of three-way joints 11. Second connecting pipes 15 are fixedly installed at the left ends of the multiple groups of solenoid valves 14. Sample storage boxes 19 are fixedly installed inside the lower ends of the wastewater detection box body 1. A baffle 20 is movably installed at the left end of the sample storage box 19. First sliding grooves 21 are symmetrically formed on the front and rear inner walls of the sample storage box 19. Multiple U-shaped frames 22 are slidably installed inside the sample storage box 19. First sliders 23 are fixedly installed on the front and rear sides of the multiple U-shaped frames 22. Docking frames 27 are movably installed inside the multiple first sliders 23. Sample storage cans 28 are movably inserted into the multiple docking frames 27. Multiple docking ports 29 are formed on the upper side of the sample storage box 19. A pushing component is arranged at the right end and the lower end of the sample storage box 19.

[0030] Through the mutual cooperation of multiple groups of solenoid valves 14 and multiple groups of second connecting pipes 15, when multiple groups of water pumps 10 extract wastewater, the wastewater samples are conveyed into the sample storage box 19. And through the pushing component, the multiple U-shaped frames 22 and multiple docking frames 27 are slidably arranged inside the sample storage box 19. Cooperating with the multiple docking frames 27 and multiple sample storage cans 28, the wastewater samples can be stored, which is convenient for subsequent operators to recheck or further analyze the wastewater samples. The arrangement of multiple docking ports 29 facilitates the entry of wastewater samples into the sample storage box 19, improving the convenience of storing wastewater samples.

[0031] As Figures 2 to 6 shown, liquid level sensors 16 are fixedly installed inside the left ends of the multiple groups of second connecting pipes 15. The multiple groups of liquid level sensors 16 are connected to the control module 4 and multiple groups of solenoid valves 14.

[0032] Through the liquid level sensors 16 installed at the left end openings of the multiple groups of second connecting pipes 15, the liquid level height of the wastewater conveyed by the multiple groups of second connecting pipes 15 into the multiple sample storage cans 28 can be monitored in real time. When the wastewater is conveyed from the multiple groups of second connecting pipes 15 into the multiple sample storage cans 28, the liquid level sensors 16 will continuously detect the liquid level of the wastewater to ensure that the wastewater does not exceed the safe height before entering the multiple sample storage cans 28, thereby preventing the wastewater from overflowing when entering the multiple sample storage cans 28 during the conveying process. And through the liquid level sensors 16, a signal can be sent to the control module 4 in time before the wastewater liquid level reaches the preset safe height. After receiving the signal, the control module 4 will instruct the multiple groups of solenoid valves 14 to close quickly, thereby cutting off the channels of the multiple groups of second connecting pipes 15 and preventing more wastewater from entering the multiple sample storage cans 28, improving the automation degree and efficiency of the entire system.

[0033] As Figures 5 to 9As shown in the figure, second sliding grooves 24 are symmetrically formed in the front and rear directions inside multiple U-shaped frames 22. Reset springs 25 are installed in multiple second sliding grooves 24, and second sliders 26 are slidably installed in multiple second sliding grooves 24. The multiple second sliders 26 are fixedly connected to the front and rear sides of multiple docking frames 27 respectively.

[0034] Through the arrangement of multiple second sliding grooves 24, multiple reset springs 25, and multiple second sliders 26, guidance and support are provided for the second sliders 26 to slide in the second sliding grooves 24, ensuring the stable sliding of the second sliders 26 in the second sliding grooves 24. Furthermore, the stable movement of the docking frames 27 and the sample storage cans 28 in the sample storage box 19 is guaranteed, improving the stability and reliability of the storage of wastewater samples. It is ensured that the pushing assembly jacks up the docking frames 27 inside the U-shaped frames 22 to dock multiple sample storage cans 28 with multiple second connecting pipes 15, thereby collecting the stored samples of the extracted wastewater and avoiding subsequent detection.

[0035] As Figures 2 to 4 shown in the figure, the pushing assembly includes first electric telescopic rods 30. The first electric telescopic rods 30 are fixedly installed on the right side of the sample storage box 19. The telescopic ends of the first electric telescopic rods 30 are fixedly installed with first push plates 31. The first push plates 31 are located inside the right end of the sample storage box 19. An activity groove 32 is formed inside the lower end of the sample storage box 19. Second electric telescopic rods 33 are fixedly installed inside the lower end of the activity groove 32. The telescopic ends of multiple second electric telescopic rods 33 are fixedly installed with second push plates 34. Multiple push blocks 35 are fixedly installed on the upper side of the second push plates 34. Multiple socket openings 36 are formed inside the lower ends of multiple U-shaped frames 22.

[0036] Through the arrangement of multiple first electric telescopic rods 30, the first electric telescopic rods 30 are enabled to push the first push plates 31 to slide the multiple U-shaped frames 22 and multiple docking frames 27 leftward in the sample storage box 19, aligning the multiple U-shaped frames 22 and multiple docking frames 27 with multiple docking openings 29 in sequence. Then, it is convenient for the operator to push the multiple U-shaped frames 22, and further drive the multiple docking frames 27 and multiple sample storage cans 28 to slide in the sample storage box 19 through the multiple U-shaped frames 22. When the U-shaped frames 22 and the docking frames 27 are aligned with the multiple docking openings 29, the second electric telescopic rods 33 drive the second push plates 34 and multiple push blocks 35 to slide upward to jack up the docking frames 27 inside the U-shaped frames 22, thereby connecting the multiple sample storage cans 28 inside the docking frames 27 with multiple second connecting pipes 15, and the collection of wastewater can be completed.

[0037] As Figures 1 to 3 shown in the figure, drain openings 17 are formed on the detection cans 5 at the rear sides of the upper ends of multiple detection chambers 6. Drain pipes 18 are movably installed on the multiple drain openings 17. The left ends of the drain pipes 18 are inserted into the left end of the wastewater detection box body 1.

[0038] Through the careful arrangement of multiple groups of drain openings 17 and drain pipes 18, it is ensured that when the wastewater enters the multiple groups of detection chambers 6, excessive influx is avoided, so that the wastewater entering the detection chamber 6 can effectively overflow when it is higher than the openings of the multiple groups of drain openings 17, and the wastewater is appropriately controlled through the drain pipes 18, preventing excessive wastewater from entering the multiple groups of detection chambers 6 and causing excessive internal pressure of the device, ensuring the normal operation of the device and the accuracy of wastewater detection.

[0039] Working principle: During use, the operator first extends and elongates multiple groups of water suction pipes 12, and inserts the extended and elongated water suction pipes 12 and water suction heads 13 into the wastewater. Subsequently, the control module 4 is used to start multiple groups of water pumps 10. When the multiple groups of water pumps 10 extract wastewater, according to the multiple groups of water suction pipes 12 and multiple groups of water suction heads 13, they penetrate into the wastewater at different depths, realizing the stratified extraction of wastewater. After the wastewater passes through the filtration of the multiple groups of water suction heads 13, impurities and particulate matters are removed to ensure the purity of the wastewater. Subsequently, it is extracted and conveyed to the multiple groups of detection chambers 6 through the first connecting pipes 9. The multiple groups of connecting lines 7 and multiple groups of detection heads 8 accurately detect the wastewater stored in the multiple groups of detection chambers 6. At the same time, during the process of the multiple groups of water pumps 10 extracting wastewater, the wastewater samples are conveyed to the sample storage box 19 through the multiple groups of three-way joints 11, multiple groups of electromagnetic valves 14, and multiple groups of second connecting pipes 15. At this time, the pushing assembly starts to work. Multiple groups of first electric telescopic rods 30 push the first push plate 31, sliding the multiple groups of U-shaped frames 22 and multiple groups of docking frames 27 to the left in the sample storage box 19 and aligning them with the multiple groups of docking ports 29 in sequence. Subsequently, the operator pushes the multiple groups of U-shaped frames 22, driving the multiple groups of docking frames 27 and multiple groups of sample storage cans 28 to slide in the sample storage box 19. When the U-shaped frames 22 and docking frames 27 are aligned with the multiple groups of docking ports 29, multiple groups of second electric telescopic rods 33 drive the second push plate 34 and multiple groups of pushing blocks 35 to slide upward and insert into the multiple groups of socket openings 36, thereby jacking up the docking frames 27 inside the U-shaped frames 22, and then connecting the multiple groups of sample storage cans 28 inside the docking frames 27 with the multiple groups of second connecting pipes 15, thus completing the collection and sample storage of wastewater. After the sample storage is completed, the operator can recheck or further analyze the wastewater samples, improving the accuracy and reliability of wastewater detection. In addition, through the careful arrangement of the multiple groups of drain openings 17 and drain pipes 18, it effectively prevents excessive wastewater from entering the multiple groups of detection chambers 6 and causing excessive internal pressure of the device.
