Description

Technical Field

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

[0002] Water quality testing is a crucial aspect of environmental protection and public health management, involving the monitoring and assessment of the types, concentrations, and trends of pollutants in water bodies. With rapid industrialization and urbanization, water pollution problems are becoming increasingly complex, and testing needs have expanded from single-indicator assessments to comprehensive multi-parameter evaluations.

[0003] However, the built-in sensor modules of existing water quality analyzers are prone to absorbing impurities when in contact with water samples for extended periods, leading to decreased sensitivity, data drift, or signal distortion. Many existing sensor module processing modules rely on external cleaning or manual maintenance. Manual cleaning requires frequent shutdowns, reducing the continuity of testing and making it difficult to completely remove stubborn contaminants. The investment of professional maintenance personnel and equipment wear and tear increases operating costs. Furthermore, the lack of an integrated cleaning mechanism prevents real-time maintenance and affects the reliability of long-term monitoring. Utility Model Content

[0031] Example 1:

[0032] Please refer to the attached document as well. Figures 1 to 4 This embodiment provides a water quality analyzer. The water quality analyzer 1 includes a detection plate 106. A sensor module and a processing module 3 are disposed on the detection plate 106. The sensor module is placed on the detection plate 106. The processing module includes a processing seat 31 that is slidably disposed on the detection plate 106. A cleaning unit 32 is disposed on the processing seat 31. The cleaning unit is used to clean the sensor module.

[0033] To make the technical solution in this embodiment clearer, the characteristic structure of the water quality analyzer is described below. Specifically, the water quality analyzer 1 further includes a detection housing 2, a detection disk 106 placed inside the detection housing 2 and fixedly connected to the detection housing 2, and a sampling component 104 disposed inside the detection housing 2. The water quality analyzer 1 also includes a liquid inlet 101 disposed above the sampling component 104. The water quality analyzer 1 uses an external sampling component to extract liquids of different water layers to be tested into the liquid inlet 101. The liquids to be tested are transported to the sampling component 104 via the liquid inlet 101. The analyzer 1 also includes a turntable 102 rotatably disposed below the detection disk 106. The outer periphery of the turntable 102 is provided with a buckle 103 for fixing the detection cup.

[0034] In some embodiments, a motor is provided below the detection disk 106. The motor is connected to the turntable 102 through a structure such as a reducer or gearbox to drive the rotation of the turntable 102, thereby enabling the detection cups detachably connected to the turntable 102 to perform detection operations. At the same time, the detection cups detachably connected to the turntable 102 can also be rotated and sampled alternately under the sampling component 104.

[0035] In some embodiments, a valve 6 is provided on the sampling tube 5. The valve 6 is preferably a CNC solenoid valve and is communicatively connected to the control unit provided in the detector 1 to realize automatic feeding.

[0036] It is understood that the motor, stirring assembly, and drive structure within the stirring unit in this embodiment are all communicatively connected to the control unit to achieve automated detection and analysis processes.

[0037] In some embodiments, the sensor modules within the detection assembly include a pH sensor unit, a DO sensor unit, a turbidity sensor unit, a conductivity sensor unit, a heavy metal sensor unit, etc.

[0038] In some embodiments, the stirring seat inside the detector 1 is provided with a notch, which is used for the sample addition process of the test cup and the test process, and to seal the remaining test cups.

[0039] In some embodiments, the completed test cups can be labeled and sealed to enable repeatability and traceability of the testing process.

[0040] In some embodiments, the sensor module is slidably disposed on the detection plate 106. Optionally, the sensor module is slidably disposed on the detection plate 106 through a structure such as a controllable slide rail 312, so as to realize the displacement of the sensor module in the vertical direction, thereby realizing the detection of the liquid to be tested in the detection cup.

[0041] In some embodiments, the sliding arrangement of the processing base 31 and the detection disk 106 can be achieved by relying on a structure such as an electric slide rail 312.

[0042] It should be noted that the built-in sensor module of the existing water quality tester 1 is prone to adsorbing impurities when in contact with water samples for a long time, which leads to decreased sensitivity, data drift or signal distortion. The existing sensor module processing module 3 relies on external cleaning or manual maintenance. Manual cleaning requires frequent shutdowns, which reduces the continuity of detection and makes it difficult to completely remove stubborn pollutants.

[0043] Based on the above problems, this embodiment proposes a built-in processing module 3 for the sensor module of a water quality analyzer 1. Through the collaborative work of a sliding processing seat 31 and a cleaning unit 32, in-situ cleaning of the sensor module is achieved. Specifically, the main body of the cleaning unit 32 is a cleaning tank 33 with a built-in ultrasonic unit. Utilizing the cavitation effect generated by high-frequency ultrasonic waves, stubborn contaminants such as microorganisms and colloidal particles attached to the surface of the sensor module can be efficiently removed without disassembling the sensor module, overcoming the bottleneck of traditional manual cleaning's inability to thoroughly remove microscopic impurities. In addition, the bottom of the cleaning tank 33 adopts an elastic support structure, which ensures uniform transmission of ultrasonic energy and avoids potential damage to the sensor module from rigid contact. At the same time, the horizontal position of the cleaning tank 33 can be adaptively adjusted to compensate for mechanical assembly errors, significantly improving cleaning stability. Furthermore, the cleaning tank 33 also integrates a mechanical brushing unit, which is linked with the guide mechanism through a rope transmission system. After ultrasonic cleaning, it performs targeted brushing on the complex structures such as grooves and gaps at the end of the sensor module, forming a dual cleaning mode of "ultrasonic + physical" to further eliminate residual contaminants.

[0044] In this embodiment, the cleaning unit 32 includes a cleaning tank 33, and an ultrasonic cleaning unit is provided in the cleaning tank 33.

[0045] Understandably, by deeply coupling the physical properties of ultrasound with the structural properties of the sensor module, a precise and controllable cleaning system is constructed. Specifically, the ultrasonic frequency is selected to match the material properties of the sensor module to avoid resonance damage; the closed tank design focuses energy and prevents cross-contamination; and the elastic support structure absorbs high-frequency vibrations in the transmission of ultrasound to ensure system stability.

[0046] The aforementioned structure leverages the unique advantages of ultrasound in microscopic cleaning while mitigating potential risks, such as cavitation corrosion, through structural innovation, demonstrating both high efficiency and safety. Compared to isolated cleaning modules in existing technologies, the ultrasonic unit in this embodiment works synergistically with the mechanical brushing and sliding positioning mechanism—ultrasonic pretreatment breaks down the binding force of contaminants, and subsequent brushing removes loose residues. The phased action of these two components significantly improves overall cleaning efficiency.

[0047] In this embodiment, the bottom of the cleaning tank 33 is provided with an elastic element 34 and is placed on the treatment seat 31 through the elastic element 34.

[0048] Understandably, matching the elastic stiffness with the ultrasonic frequency ensures vibration isolation while preventing excessive amplitude in the cleaning tank 33 due to excessive flexibility. The symmetrical distribution of multiple elastic elements 34 ensures balanced load and prevents tank tilting. The elastic deformation range matches the tolerance band of the sensor module, achieving precise adaptation within finite degrees of freedom. Compared to existing technologies that use rigid bolts for fixing or simple rubber pads for vibration damping, the design of the elastic element 34 in this embodiment not only solves the single-dimensional vibration problem but also achieves systematic adaptation to complex working conditions through a three-dimensional compliance mechanism.

[0049] In some embodiments, the elastic element 34 is a spring, more preferably a spring evenly distributed at the four corners, etc.

[0050] In this embodiment, the processing seat 31 is provided with a vertical plate 311, a slide rail 312 is provided on the vertical plate 311, a slide block 313 is provided on the slide rail 312, and a sliding ball 314 is provided on the side of the slide block 313 near the cleaning unit 32. The cleaning tank 33 is provided with a protrusion 315 on the side near the vertical plate 311, and the protrusion 315 abuts against the sliding ball 314.

[0051] In this embodiment, the geometric centers of the slider 314 and the protrusion 315 are located on the same straight line.

[0052] It is understandable that the slider 314 and the protrusion 315 abut against each other and their geometric centers are collinear, forming a dynamic pressure transmission system. When the slide 313 moves up and down along the slide rail 312, the slider 314 applies periodically changing contact pressure to the protrusion 315, forcing the cleaning tank 33 to produce a controllable lateral dynamic offset under the support of the elastic element 34. This offset is not a random sway, but rather, through the geometric matching of the movement trajectory of the slider 314 and the arc surface of the protrusion 315, the vertical linear motion of the slide 313 is transformed into the horizontal reciprocating oscillation of the cleaning tank 33, forming a motion conversion mechanism of vertical drive and horizontal response. This breaks through the limitations of the traditional straight cleaning path, extending the range of ultrasonic cavitation effect and mechanical brushing from the static area to the dynamic coverage area. Especially for contaminants on irregular depressions or sidewalls of sensor module surfaces, such as calcification deposits on the inner wall of tubular electrodes, the dynamic offset guides the cleaning fluid to form an alternating vortex scouring and brushing path coverage, significantly improving the cleanliness of complex structural surfaces.

[0053] In this embodiment, a pulley 316 is provided on the upright plate 311. A cleaning unit 35 is slidably disposed within the cleaning tank 33. The cleaning unit 35 includes a cleaning seat 351 slidably disposed with the cleaning tank 33, and a cleaning brush 352 matching the end of the sensor module is provided on the cleaning seat 351. A sliding rope 353 is provided at the end of the cleaning seat 351, and the free end of the sliding rope 353 is connected to the upper end surface of the sliding base 313 after passing through the pulley 316.

[0054] Understandably, a sliding rope 353 is fixed to the end of the cleaning seat 351. The sliding rope 353 passes around the pulley 316 on the vertical plate 311 and connects to the upper end of the slide seat 313, forming a vertical-horizontal motion conversion mechanism. When the slide seat 313 is driven to move up and down along the slide rail 312, the free end of the sliding rope 353 is pulled or released as the slide seat 313 rises and falls, forcing the cleaning seat 351 to slide back and forth along the guide rail in the cleaning tank 33, driving the cleaning brush 352 to perform linear or arc-shaped brushing on the surface of the sensor module. The geometric center of the ball 314 and the protrusion 315 are collinear, ensuring that the pressure transmission direction of the ball 314 on the protrusion 315 when the slide seat 313 moves is consistent with the traction direction of the sliding rope 353, eliminating the transmission lag caused by the lateral component force or the uneven wear of the sliding rope 353, so that the movement trajectory of the cleaning brush 352 is synchronized and coordinated with the dynamic offset of the cleaning tank 33, forming a multi-level cleaning mode of ultrasonic cavitation to disintegrate contaminants, dynamic offset to expand the range of action, and mechanical brushing to remove loose residues.

[0055] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
