Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, specifically to a water quality testing and analysis device. Background Technology

[0002] Water quality electrochemical testing is widely used in environmental monitoring, tap water quality inspection, aquaculture, and laboratory water sample analysis due to its advantages such as high detection accuracy, fast response speed, portable equipment, and wide applicability. Conventional water quality testing equipment adopts an integrated analytical rod structure with integrated detection electrodes at the end of the analytical rod. During the testing operation, the analytical rod is directly inserted vertically into the water cup or beaker containing the water sample to be tested. The parameters such as ion concentration, dissolved oxygen, pH, and conductivity are collected by relying on the direct contact between the electrode and the water.

[0003] Currently, water quality testing and analysis devices rely on dissolved gases such as air and carbon dioxide within the water sample. During the water's settling process, tiny gas nuclei form micron-sized bubbles on the surface of the detection electrode and at the microscopic unevenness of the sensing membrane. As a large number of bubbles accumulate, they form a continuous, sealed gas film on the outer wall of the detection head. This gas film provides insulation and isolation, directly blocking effective contact between the electrode sensing area and the water being tested. This leads to multiple measurement malfunctions, resulting in no readings, numerical drift, and prolonged instability, thus reducing the efficiency of water quality testing.

[0004] To address the above issues, a water quality detection and analysis device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a water quality detection and analysis device. By using this device, the problem mentioned above can be solved: when a large number of bubbles accumulate, they form a continuous closed gas film on the outer wall of the detection head. This gas film has an insulating effect, which directly leads to no reading, numerical drift, and long-term instability, thus reducing the efficiency of water quality detection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A water quality detection and analysis device includes an analyzer body and a wire installed on one side of the analyzer body. A detection rod is installed at one end of the wire, and a detection head is provided at one end of the detection rod. Several bearings are fixedly installed on the surface of the detection rod. A rotating cylinder is rotatably connected to the surface of the detection rod, and the rotating cylinder is slidably engaged with the surface of the bearings. A driving component for driving the rotating cylinder to rotate is installed on one side of the detection rod. A rotating component is provided at one end of the detection rod. The driving component is connected to the rotating component and the rotating component is slidably engaged with the rotating cylinder. Several shearing components are installed inside one end of the rotating cylinder. The driving component continuously outputs power to drive the rotating cylinder and the shearing components to rotate synchronously around the detection head. The shearing components form a continuous circumferential shearing water flow in the annular gap between the detection head and the rotating cylinder, continuously cutting and tearing the micron-sized microbubbles and continuous insulating gas films attached to the outer wall of the detection head.

[0007] Furthermore, several sliding plates are fixedly installed inside the rotating cylinder, and the sliding plates are slidably connected to the bearing and the rotating component respectively.

[0008] Furthermore, the inner side of the end of the rotating cylinder is provided with several guide grooves, and the shearing component is disposed inside the guide grooves. The end of the rotating cylinder is provided with several through holes near the shearing component.

[0009] Furthermore, the driving component includes a dual-axis motor and a corresponding mounting bracket on the surface of the dual-axis motor. The mounting bracket is fixedly connected to the detection rod. A gear is fixedly mounted on one end of the dual-axis motor, and the gear meshes with the rotating component. A threaded rod is mounted on the other end of the dual-axis motor.

[0010] Furthermore, the rotating component includes a fixed plate and a geared disc rotatably connected to the surface of the fixed plate. The fixed plate is fixedly connected to the detection rod, the gear and the geared disc are meshed, the sliding plate is slidably connected to the geared disc, and a first rotating ring is fixedly installed on one side of the geared disc, and the first rotating ring is rotatably connected to the fixed plate.

[0011] Furthermore, the fixed plate has a rotating groove inside, and the first rotating ring is rotatably connected to the rotating groove.

[0012] Furthermore, the shearing component includes blades and several springs fixed to one side of the blades. The blades are slidably connected to the guide grooves, and the springs are fixedly connected to the inner side of the guide grooves.

[0013] Furthermore, one end of the blade is provided with an inclined surface.

[0014] Furthermore, a lifting component is slidably connected to the surface of the detection rod. The lifting component includes a cylinder and a threaded sleeve fixed inside the cylinder. The cylinder is slidably connected to the surface of the detection rod, and the threaded rod is threadedly connected to the threaded sleeve.

[0015] Furthermore, a connector is installed inside one end of the rotating cylinder. The connector includes a fixed ring and a second rotating ring fixed inside the fixed ring. The fixed ring is fixedly connected to the inside of the rotating cylinder. Several balls are installed on both sides of the second rotating ring, and the balls are in rolling connection with the inside of the cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The drive unit drives the rotating cylinder and shearing unit to rotate continuously and at a constant speed, forming a surrounding shearing water flow around the detection head. This continuously tears and peels off the micron-level microbubbles and continuous insulating gas films on the surface of the detection head, breaking the bubble insulation isolation layer. This ensures that the electrode sensing area is in full contact with the water sample, avoiding numerical jumps, drifts, and reading timeouts caused by bubbles blocking the electrodes, and significantly improving the stability of water quality detection results.

[0017] 2. It can flexibly change the relative height between the shearing component and the sensing area of ​​the detection head, and adapt to water samples with different bubble contents and different settling states for high-bubble water samples and low-bubble stratified water samples.

[0018] 3. The annular circulation formed by the rotation of the shearing component continuously pushes fresh water sample that has not undergone polarization reaction in the container to the surface of the electrode of the detection head, constantly replacing the polarized water layer enriched with ions at the electrode interface, accelerating the ion exchange rate at the electrode interface, shortening the electrode potential equilibrium period, and eliminating the need for long periods of static waiting for the reading to stabilize.

[0019] 4. The slow, circular rotation of the shearing component generates a gentle circulation, which slowly and homogenizes the still water sample inside the container, breaking up the vertical temperature stratification formed by the water's static state. This ensures that the water temperature in the area where the detection head is located is consistent with the overall temperature of the water sample, and the collected temperature values ​​accurately represent the overall temperature of the water sample, providing precise basic data for temperature compensation calculations of water quality parameters.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-3 As shown, a water quality detection and analysis device includes an analyzer body 1 and a wire 2 installed on one side of the analyzer body 1. A detection rod 3 is installed at one end of the wire 2. The analyzer body 1 and the detection rod 3 are flexibly connected by the wire 2. The detection rod 3 can freely extend into various small water sample containers such as beakers, sampling cups, and field water collection containers, without being restricted by the position of the analyzer body 1. The on-site and laboratory water collection and testing operations are flexible and portable. A detection head 4 is set at one end of the detection rod 3. The detection head 4 integrates a water quality sensing electrode, which directly contacts the water body to complete the collection of multiple water quality parameters such as pH, dissolved oxygen, conductivity, and ion concentration. It has a high degree of integration.

[0024] To address the technical problem that a large number of air bubbles accumulate and form a continuous, closed air film on the outer wall of the detection head 4, which has an insulating effect and directly leads to no readings, numerical drift, and prolonged instability, thus reducing the efficiency of water quality testing, the following preferred technical solution is provided: like Figures 1-3As shown, several bearings 5 ​​are fixedly installed on the surface of the detection rod 3. A rotating cylinder 6 is rotatably connected to the surface of the detection rod 3, and the rotating cylinder 6 is slidably engaged with the surface of the bearings 5. Multiple sets of bearings 5 ​​surround and support the rotating cylinder 6. The bearings 5 ​​convert the hard friction between the rotating cylinder 6 and the detection rod 3 into rolling friction, greatly reducing the rotational resistance. A driving component 7 for driving the rotating cylinder 6 is installed on one side of the detection rod 3, and a rotating component 8 is provided at one end of the detection rod 3. The driving component 7 is connected to the rotating component 8, and the rotating component 8 is slidably engaged with the rotating cylinder 6. The driving component 7 serves as a dedicated power source, enabling uninterrupted and uniform active rotation without stopping after a few rotations. It can continuously flush the detection head 4 with water throughout the process, preventing the re-adsorption of air bubbles after cleaning. Several shearing components are installed inside one end of the rotating cylinder 6. 9. The shearing components 9 are concentrated at the end of the rotating cylinder 6 near the detection head 4, directly within the narrow annular gap on the outer wall of the detection head 4. When rotating, they can act on the electrode surface at close range, forming a high-intensity shearing water flow for micron-sized microbubbles and thin air films. The bubble removal efficiency is high. Multiple shearing components 9 are arranged around the detection head 4, covering the outer periphery of the detection head 4 in 360° all-round when rotating, without any scouring blind spots. They can simultaneously remove all the attached bubbles around the detection head 4, avoiding localized numerical drift caused by residual air films. The driving component 7 continuously outputs power to drive the rotating cylinder 6 and the shearing components 9 to rotate around the detection head 4 synchronously. The shearing components 9 form a continuous circumferential shearing water flow in the annular gap between the detection head 4 and the rotating cylinder 6, continuously cutting and tearing the micron-sized microbubbles and continuous insulating air films attached to the outer wall of the detection head 4. The analyzer body 1 transmits signals and supplies power through the wire 2. During the test, the operator immerses the part of the test rod 3 with the test head 4 into a beaker or cup containing a static water sample. The test head 4 integrates an electrochemical electrode and a temperature sensing element, which can contact the water body to collect water quality parameters such as pH, dissolved oxygen, ion concentration, and conductivity. The drive unit 7 serves as the power output unit, and the power output end is connected to the rotating part 8 at the end of the test rod 3. The power is transferred to the rotating cylinder 6 after being transferred through the rotating part 8. The rotating part 8 and the end of the rotating cylinder 6 adopt a sliding snap-fit ​​fit, which can stably transmit torque to drive the rotating cylinder 6 to rotate synchronously, and can also reserve axial movement margin to provide an assembly basis for subsequent vertical height adjustment of the rotating cylinder 6. The driving component 7 continuously outputs torque at a constant speed, driving the rotating component 8, rotating cylinder 6, and shearing component 9 to synchronously perform uninterrupted circular rotation around the detection head 4. During the continuous rotation of the shearing component 9, a surrounding directional shearing water flow is formed in the annular gap on the outer wall of the detection head 4. The shearing water flow continuously washes and cuts the sensing outer wall of the detection head 4, tearing and breaking apart the micron-sized microbubbles and continuous insulating gas films attached to the surface of the detection head 4, breaking the insulating isolation layer formed by the bubbles, and allowing the electrode sensing area to maintain unobstructed contact with the water sample to be tested. Continuous rotation can prevent secondary adsorption and attachment of bubbles, and maintain the defoaming and rinsing effect throughout the process. The annular circulation formed by the rotation of the shearing element 9 continuously pushes fresh water sample that has not undergone polarization reaction into the electrode surface of the detection head 4, constantly replacing the polarized water layer rich in ions at the electrode interface, accelerating the ion exchange rate at the electrode interface, shortening the electrode potential equilibrium period, eliminating the need for long periods of static waiting for the reading to stabilize, and the low-speed annular rotation of the shearing element 9 generates a gentle circulation, slowly and homogenizing the static water sample inside the container, breaking the vertical temperature stratification formed by static water, ensuring that the water temperature in the area where the detection head 4 is located is consistent with the temperature of the entire water sample, and the collected temperature value can truly represent the overall temperature of the water sample.

[0025] like Figure 4 and Figure 6 As shown, several sliding plates 61 are fixedly installed inside the rotating cylinder 6, and the sliding plates 61 are slidably connected to the bearing 5 and the rotating part 8 respectively. The sliding plates 61 are in a sliding fit relationship with the bearing 5 and the rotating part 8. While ensuring the circumferential rotation accuracy, the axial up and down sliding stroke of the rotating cylinder 6 is not limited. When the equipment needs to adapt to different length detection electrodes and adjust the height of the shearing part 9 relative to the sensing area of ​​the detection head 4, the rotating cylinder 6 can smoothly complete the axial lifting and lowering adjustment by relying on the sliding plates 61, always matching the optimal working height, ensuring that the core effects of defoaming, water mixing and polarization layer replacement are not reduced, and greatly improving the device's adaptability to multiple specifications of detection electrodes. Several guide grooves 62 are provided on the inner side of the end of the rotating cylinder 6, and the shearing parts 9 are set inside the guide grooves 62. The shearing parts 9 are limited and assembled inside the guide grooves 62, which can achieve precise positioning and regular arrangement of the shearing parts 9. This effectively avoids the shearing parts 9 from shifting, tilting, loosening or angular misalignment under long-term rotation and water flow impact conditions. It makes the spacing and tilt angle of each shearing part 9 relative to the outer wall of the detection head 4 uniform, and the overall rotation concentricity is higher. The water flow shearing intensity in the annular gap is uniform in the circumferential direction, ensuring the all-round and uniform peeling and tearing effect on the microbubbles and continuous air films on the outer wall of the detection head 4. The working conditions are more stable. Several through holes 63 are opened at the end of the rotating cylinder 6 near the shearing component 9. The through holes 63 cooperate with the shearing component 9 to allow the water in the upper and lower layers of the container to complete vertical convection exchange through the through holes 63. Combined with the annular circulation effect of the shearing component 9, the mixing effect of water body is upgraded from single horizontal stirring to a composite water body mixing effect of annular shearing and vertical convection. This can eliminate the temperature stratification of water body in the water cup more efficiently and uniformly, and make the water temperature around the detection head 4 highly consistent with the overall temperature of the water sample. This effectively eliminates the temperature compensation calculation deviation caused by temperature stratification and significantly improves the data consistency and measurement accuracy of multiple parallel tests.

[0026] like Figure 5As shown, the drive unit 7 includes a dual-axis motor 71 and a corresponding mounting bracket 72 installed on the surface of the dual-axis motor 71. The mounting bracket 72 is fixedly connected to the detection rod 3. A gear 73 is fixedly installed at one end of the dual-axis motor 71, and the gear 73 meshes with the rotating part 8. A threaded rod 74 is installed at the other end of the dual-axis motor 71. When the dual-axis motor 71 rotates at a constant speed in the forward direction, the power is transmitted to the rotating part 8 through the meshing of the gear 73. The rotating part 8 then drives the rotating cylinder 6 and the shearing part 9 to rotate continuously in a ring around the detection head 4 through the sliding plate 61 that is slidably engaged. The shearing part 9 generates a surrounding shearing water flow to complete the bubble removal, polarized water replacement, and water temperature equalization operations, so as to achieve stable detection of the detection head 4 without bubbles.

[0027] like Figure 7 As shown, the rotating component 8 includes a fixed plate 81 and a gear disk 82 rotatably connected to the surface of the fixed plate 81. The fixed plate 81 is fixedly connected to the detection rod 3. The gear 73 and the gear disk 82 are meshed and connected. The gear 73 and the gear disk 82 mesh and transmit power. The transmission ratio is constant and the torque transmission efficiency is high. There is no problem of slippage or loss of rotation due to friction transmission. The output speed of the dual-axis motor 71 can be accurately and synchronously transmitted to the gear disk 82 to ensure that the rotation speed of the shearing component 9 is constant and the intensity of the annular shearing water flow is uniform and stable. This avoids the problem of fluctuating defoaming effect and drifting detection values ​​caused by speed fluctuations. The sliding plate 61 is slidably connected to the gear disk 82. A first rotating ring 83 is fixedly installed on one side of the gear disk 82 and is rotatably connected to the fixed plate 81. The first rotating ring 83 serves as a rotating support for the gear disk 82 and forms an annular rotating pair with the fixed plate 81. It provides all-round axial and radial limit for the gear disk 82 to prevent tilting, eccentricity and axial movement during the rotation of the gear disk 82. The fixed plate 81 has a rotating groove 811 inside, and the first rotating ring 83 is rotatably connected to the rotating groove 811. The first rotating ring 83 is embedded in the rotating groove 811 to achieve limited rotation. Compared with the external rotating fit structure, it can form all-round radial and axial limits on the first rotating ring 83 and the overall gear disk 82, strictly limiting the radial offset, tilt and axial movement of the gear disk 82 during operation, ensuring that the gear disk 82 rotates precisely coaxially around the central axis throughout the entire process, so that the gear 73 and the gear disk 82 always maintain a standard meshing state, without uneven wear, skipped teeth and jamming, and higher power transmission accuracy. It avoids speed fluctuation caused by transmission eccentricity from the structural root, and ensures uniform rotation of the shearing part 9 and stable water flow shearing effect.

[0028] like Figure 6As shown, the shearing component 9 includes a blade 91 and several springs 92 fixed to one side of the blade 91. The blade 91 is slidably connected to the guide groove 62, and the springs 92 are fixedly connected to the inner side of the guide groove 62. When scale, fine mud, sand, or water impurities adhere to the guide groove 62 and the surface of the blade 91, the blade 91 can shake off and peel off the attached impurities by slight expansion and contraction vibration during rotation, thus achieving self-cleaning of the structure. At the same time, during the upward sliding of the rotating cylinder 6, the end of the blade 91 will come into contact with and squeeze the outer wall of the end of the detection rod 3. After being subjected to hard pressure, the blade 91 will slide inward along the channel of the guide groove 62 to compress the spring 92. The spring 92 will generate elastic contraction deformation, allowing the blade 91 to retract into the guide groove 62. The blade 91 will retreat inward to make room for avoidance, preventing the blade 91 from rigidly jamming, stuck, or scraping against the end of the detection rod 3 and the outer wall of the detection head 4. This ensures that the rotating cylinder 6 can smoothly complete the entire upward and downward displacement without mechanical obstruction, and the detection head 4 can be exposed. One end of the blade 91 is provided with an inclined surface 93. When the rotating cylinder 6 is adjusted upward and downward and the blade 91 approaches and contacts the end of the detection rod 3, the inclined surface 93 can first form an inclined contact with the edge of the end of the detection rod 3, converting the vertical upward resistance into a horizontal inward component force, which guides the blade 91 to slide inward along the guide groove 62 and compress the spring 92. The inclined surface 93 has an adaptive guiding and yielding function, making the process of the blade 91 retracting and avoiding obstacles smoother, ensuring that the upward and downward stroke of the rotating cylinder 6 is not obstructed, and greatly improving the smoothness and stability of the height adjustment operation.

[0029] To address the technical problem of insufficient defoaming in high-bubble conditions and inadequate mixing in low-layer conditions, which are both unsatisfactory, the following preferred technical solution is provided: like Figure 4 , Figure 5 and Figure 8 As shown, a lifting component 10 is slidably connected to the surface of the detection rod 3. The lifting component 10 includes a cylinder 101 and a threaded sleeve 102 fixed inside the cylinder 101. The cylinder 101 is slidably connected to the surface of the detection rod 3. The threaded rod 74 is threadedly connected to the threaded sleeve 102. The rotational motion of the threaded rod 74 is converted into a linear lifting and lowering micro-displacement of the threaded sleeve 102 through the threaded pair. The threaded sleeve 102 is rigidly fixed to the cylinder 101. The cylinder 101 is guided by the outer wall of the detection rod 3, thereby driving the entire lifting component 10 to move up and down slightly in sync. Finally, it pulls the rotating cylinder 6 to move up and down along the axis of the detection rod 3, which can change the relative height between the blade 91 and the sensing area of ​​the detection head 4. High-bubble water samples, aerated water samples, surface running water, and disturbed water samples are prone to forming a continuous thick insulating gas film on the surface of the detection head 4. When the shearing position of the blade 91 is misaligned, the scouring distance is too far, and the shearing force is insufficient, it can only break up scattered microbubbles and cannot tear the overall gas film. As a result, the electrode is still blocked by the gas film and has poor contact. When the height of the blade 91 is lowered, the blade 91 can completely cover the electrode sensing area, enhance the close-range shearing and scouring, quickly tear the thick continuous gas film, and prevent bubbles from blocking the electrode. When low-bubbling, easily stratified water samples are present, the blade height is increased by 91 degrees to expand the circulation range, increase vertical convection of the water, fully eliminate water temperature stratification between the upper and lower parts of the container, optimize temperature homogenization, and reduce temperature compensation error.

[0030] like Figure 4 and Figure 8 As shown, a connector 20 is installed inside one end of the rotating cylinder 6. The connector 20 includes a fixed ring 201 and a second rotating ring 202 fixed inside the fixed ring 201. The fixed ring 201 is fixedly connected to the inside of the rotating cylinder 6. Several balls 203 are installed on both sides of the second rotating ring 202. The second rotating ring 202 and the cylinder 101 form a rolling friction pair by means of the balls 203, which transforms the traditional sliding hard friction into rolling friction of the balls 203, greatly reducing the frictional resistance when the rotating cylinder 6 rotates, ensuring that the shearing piece 9 rotates at a uniform speed and smoothly, and continuously generating shearing water flow to complete defoaming and mixing. The balls 203 are rolledly connected to the inside of the cylinder 101. The dual-axis motor 71 drives the threaded rod 74 to rotate, causing the threaded sleeve 102 and the cylinder 101 to slide up and down along the axis of the detection rod 3. When the cylinder 101 is axially displaced, the ball bearing 203 and the second rotating ring 202 are fitted and limited to form an axial linkage structure. The cylinder 101 can pull the second rotating ring 202, the fixed ring 201 and the overall rotating cylinder 6 to move up and down synchronously, and freely adjust the height of the shearing piece 9 relative to the sensing area of ​​the detection head 4. The circumferential rotation operation is not affected during the lifting process.
