Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to an online water quality testing instrument. Background Technology

[0002] Water quality is crucial to ecological security and human health, serving as a vital indicator in water resource management and environmental protection. Common pollutants in water bodies, such as suspended solids, heavy metals, organic matter, and microorganisms, affect water transparency, oxygen content, and chemical properties. To achieve real-time monitoring and timely intervention in water pollution, online water quality monitoring instruments are widely used in waterworks, sewage treatment plants, rivers, and lakes for long-term continuous monitoring of various key parameters in the water. Utilizing electrochemical sensing, optical detection, and colorimetry, these instruments automatically collect and transmit data, enabling dynamic tracking and early warning responses to water quality changes.

[0003] Existing online water quality analyzers typically require placing the sample container at the detection position and using mechanical structures or limiting devices for positioning to ensure effective sample acquisition by the sensor. However, due to factors such as inconsistent sample bottle specifications and limited fixing methods, the container is prone to shaking or shifting during the detection process, affecting the precise alignment between the detection head and the sample, and consequently causing fluctuations or errors in the measurement data. Therefore, this paper proposes an online water quality analyzer to address these issues. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-4This utility model provides an embodiment of an online water quality analyzer, comprising a detection box 1, inside which is a detector 2 (existing technology, not described in detail here), used for analyzing water samples. An electric slide rail 3 is fixedly connected to the inner wall of the detection box 1, and a lifting plate 4 is slidably connected to the side wall of the electric slide rail 3. A detection head 5 is installed inside the lifting plate 4, connected to the detector 2, ensuring rapid and accurate transmission of the sampling signal, enhancing response speed and measurement reliability. A placement rack 6 is fixedly connected inside the detection box 1 for orderly placement of multiple samples to be tested. A sliding plate 7 is slidably connected inside the placement rack 6, and a fixing mechanism is provided inside the sliding plate 7 to effectively fix the sample container and prevent errors caused by shaking during the testing process. A positioning mechanism is provided inside the placement rack 6 for precise sample positioning. The position ensures the alignment of the detection head 5 with the sample; the fixing mechanism includes a clamping plate 11, a fixing ring 8 fixedly connected inside the sliding plate 7, a sleeve 9 fixedly connected to the inner wall of the fixing ring 8, a sliding rod 10 slidably connected inside the sleeve 9, the clamping plate 11 fixedly connected to the side wall of the sliding rod 10, and an elastic rope 12 fixedly connected between the clamping plates 11. The elastic rope 12 gives the clamping plate 11 elastic tension, enabling it to have an automatic clamping function, effectively adapting to sample bottles of different specifications. The clamping plates 11 are arranged in a ring array to form a balanced and stable clamping force. The fixing ring 8 is located directly below the detection head 5. Multiple detection heads 5 are arranged in a linear array at equal intervals, which can realize the simultaneous or time-sharing detection of multiple water samples. The number of fixing rings 8 matches the number of detection heads 5. A door 18 is provided on the front side of the detection box 1, and an acrylic plate 19 is provided inside the door 18.

[0032] Reference Figure 3 and Figure 5 The positioning mechanism includes a locking block 16 and a recess 13 inside the slide plate 7. A fixing sleeve 14 is fixedly connected inside the placement frame 6. A slider 15 is slidably connected inside the fixing sleeve 14. The slider 15 can slide freely along the axial direction of the fixing sleeve 14 to ensure that the locking block 16 can flexibly insert into or exit from the recess 13. The locking block 16 is fixedly connected to the side wall of the slider 15. The sliding of the slider 15 drives the locking block 16 to move back and forth, thereby achieving locking or disengagement. The locking block 16 is slidably connected inside the recess 13 to prevent the slide plate 7 from shifting due to vibration during the detection process, ensuring the accurate alignment of the detection head 5 with the sample. A spring 17 is provided inside the fixing sleeve 14. One end of the spring 17 is fixedly connected inside the fixing sleeve 14, and the other end of the spring 17 is fixedly connected to the side wall of the slider 15, so that the spring 17 always remains taut during the movement of the slider 15, providing a continuous locking force. A rubber pad 20 is fixedly connected to the side wall of the placement frame 6 and is located at the bottom of the slide plate 7.

[0033] Working principle: When using this device for water quality testing, the collected sample can be placed inside the fixing ring 8. When placing the sample, by pulling the slide plate 7 outward, it applies pressure to the locking block 16, thereby squeezing it into the fixing sleeve 14 and causing the spring 17 to deform. After the locking block 16 slides out from the recess 13, the slide plate 7 can be pushed out from the placement rack 6, and then the sample can be placed. The sample container is placed inside the clamping plate 11 and pressed down, causing the clamping plate 11 to be squeezed outward, so that the slide rod 10 slides inside the sleeve 9, thereby stretching the elastic rope 12. When the bottom of the container contacts the rubber pad 20, the sample placement is completed. Then, the slide plate 7 can be pushed back into the placement rack 6, and the locking block 16 can be reinserted into the recess 13 to fix the slide plate 7, ensuring that the sample is directly below the detection head 5. Finally, by starting the device, the lifting plate 4 moves the detection head 5 downward, inserting the detection head 5 into the sample, and then the water quality is tested by the detector 2.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
