[0002] Environmental protection has always been a top priority for monitoring. The quality of water bodies affects all aspects of human production and life, making water quality testing and analysis particularly important. Water plant laboratories, third-party testing companies, sewage treatment plants, chemical plants, aquaculture water, drinking water, tap water, and swimming pool water all require water quality testing and analysis devices to detect one or more parameters.

[0003] In existing technologies, due to differences in water properties, analytical objectives, and analytical items, sampling points, sample quantities, samplers, and sampling methods also vary. Real-time water quality testing and analysis devices cannot directly test water samples from water sources. Before testing, the collection, filtration, and preservation of water samples can cause physical, chemical, and biological changes, ultimately leading to significant errors in the component detection results. Therefore, a water quality testing and analysis device is proposed to address these issues. Utility Model Content

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] As shown in the figure, a water quality testing and analysis device includes a testing chamber 1 and a detector 2 mounted on top of the testing chamber 1. A detection probe 3 is located inside the testing chamber 1 at the bottom of the detector 2. Inside the testing chamber 1, a water injection mechanism, a filtration mechanism, and a mixing mechanism are arranged sequentially. A communication port 4 is provided between the filtration mechanism and the mixing mechanism. The testing chamber 1 also has a drain outlet 5, and a shut-off valve 6 is installed on the drain outlet 5. The overall device has a simple structure and strong practicality.

[0023] The water injection mechanism includes a first inlet pipe 7, a second inlet pipe 8, and a sampling cylinder 9. The first inlet pipe 7 is made of glass, and the second inlet pipe 8 is made of plastic. The two sides of the sampling cylinder 9 are rotatably connected to the detection box 1 via rotating shafts 10, which penetrate the side wall of the detection box 1. A rotary motor 11 is fixedly connected to the through end of the rotating shaft 10. A pressure sensor 12 is installed inside the sampling cylinder 9, which converts water pressure into an electrical signal for transmission. Both the first inlet pipe 7 and the second inlet pipe 8 are equipped with a water injection pump 13 and an electrically controlled valve 14, which are movably connected inside both the first and second inlet pipes 7 and 8. Specifically, the electrically controlled valve 14 can move up and down inside the first inlet pipe 7 to control the flow rate of water within it.

[0024] The filtration mechanism includes a filter plate 15 and a cleaning nozzle 16. The filter plate 15 is inclinedly positioned below the sampling cylinder 9. A viewing window 17 is provided on the side wall of the detection chamber 1, corresponding to the downwardly inclined end of the filter plate 15. The viewing window 17 is sealed and movably connected to the detection chamber 1. Personnel can observe the internal cleanliness of the detection chamber 1 through the viewing window 17, or open the viewing window 17 to manually clean the detection chamber 1. In addition, the cleaning nozzle 16 is equipped with a fixedly connected cleaning water tank (not shown in the figure), which can automatically clean the detection chamber 1 periodically.

[0025] The mixing mechanism includes a stirring shaft 18 and a stirring paddle 19. The stirring shaft 18 penetrates the side wall of the detection box 1, and a servo motor 20 is fixedly connected to the through end of the stirring shaft 18. The detector 2 also includes a control display 21 and control buttons 22. The control display 21 is electrically connected to the pressure sensor 12, control buttons 22, servo motor 20, rotary motor 11, water pump 13, and electric control valve 14, resulting in a high degree of automation.

[0026] In practical use, the sampling volume is set according to the analysis purpose. The first inlet pipe 7 or the second inlet pipe 8 is selected to connect to the water source based on its properties (the second inlet pipe 8, made of plastic, is used for detecting inorganic matter, metals, and radioactive elements; the first inlet pipe 7, made of glass, is used for detecting organic matter and microbial indicators). The sampling volume is adjusted by moving the electric control valve 14 up and down, regulating the flow rate of water entering the sampling cylinder 9 from the first inlet pipe 7 over a period of time. The electric control valve 14 moves up to a preset height and closes at a set time, enabling precise control of the sampling volume. Simultaneously, the pressure sensor 12 inside the sampling cylinder 9 reaches a preset value, transmitting an electrical signal to the control display 21. The control display 21 controls the rotary motor 11, driving the rotating shaft 10 to rotate 90°. The water sample in the sampling cylinder 9 passes sequentially through the filter plate 15 and the connecting port 4. Then, the sampling cylinder 9 resets, and simultaneously, the servo motor 20 starts, and the stirring paddle 19 mixes the sample. The detection probe 3 detects the water sample, and in conjunction with the detector 2, the detection results are displayed on the control display 21, allowing staff to view the results at any time. After testing, the water sample can be discharged from the device through drain outlet 5 to prepare for the next water sample testing process.

[0027] Therefore, this utility model uses the above-mentioned water quality testing and analysis device to directly draw water from the external source into the testing chamber. The sampling amount and water inlet pipe are determined according to the water properties and analysis purpose. With the help of the detection probe, it can detect in real time and ensure the accuracy of the test results.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
