Detailed Implementation
[0028] 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.
[0029] Please see Figures 1-9 This invention provides a technical solution: a portable multi-parameter water quality analyzer for on-site comparative testing of marine water quality monitoring equipment, comprising an analyzer body 1 and a control panel 4, the control panel 4 being rotatably connected to the analyzer body 1, and an installation groove 6 being provided on one side of the analyzer body 1 near the control panel 4, wherein the installation groove 6 contains:
[0030] The optical detection component is equipped with three illumination modes: long-wavelength light, fluorescence, and diffused light. It can detect the turbidity, dissolved matter, and fluorescence effects of water.
[0031] The oxygen content detection component can detect the oxygen demand of water through chemical means. The oxygen content detection component is equipped with a feeding component, which can automatically mix the water sample with chemical reagents.
[0032] The electrode detection assembly is located on one side of the mounting slot 6 and is capable of detecting the metal content in the water sample.
[0033] During operation, the control screen 4 of this invention can be folded and stored. After storage, the main body 1 of the detector is a rectangular block, making it convenient for users to carry to the marine water quality survey site. When marine water quality needs to be tested, staff can place the collected water sample onto the optical detection component. The turbidity, solubility, and fluorescence effects of the water sample are detected through the three light distributions of the optical detection component: diffused light, long-wave light, and fluorescence. Simultaneously, water samples can be directly collected from the optical detection component and fixed into the feeding component. The feeding component collects the corresponding chemical reagents required for the test, mixes them, and then transports the water sample to the oxygen content detection component for oxygen demand detection. At the same time, the electrode detection component can be placed inside the optical detection component to detect the metal element content in the water, thereby achieving multi-dimensional and multi-dimensional analysis of a single water sample. The system utilizes oxygen content detection and electrode detection components to detect compounds and metal elements in water samples, while optical detection components detect turbidity and fluorescence. This allows users to obtain more comprehensive water quality data during on-site surveys, increasing the accuracy and representativeness of the data. Multiple detection devices can work together simultaneously, comparing values obtained through different detection methods to avoid the collective errors that can occur with single detection methods. Data from different detection modes can be compared and verified to mitigate potential errors during the testing process. The simultaneous use of multiple detection methods, coupled with the standardized equipment, eliminates the need to carry multiple sets of devices, simplifying operation for staff and increasing testing efficiency.
[0034] As a further embodiment of the present invention, the optical detection assembly includes an optical detection box 13, which is fixedly installed in the mounting groove 6. Multiple sets of detection lights 24 are fixedly installed at the bottom of the optical detection box 13. A light shield 14 is rotatably installed at the upper end of the optical detection box 13. A side extension tube 23 is fixedly installed on one side of the lower end of the optical detection box 13. Multiple sets of colorimetric grooves 12 are evenly arranged below the side extension tubes 23 in the mounting groove 6. Drip holes are opened on the side extension tubes 23 at positions corresponding to the colorimetric grooves 12.
[0035] During operation, the water sample is injected into the optical detection chamber 13. In actual testing, the light shield 14 is closed and the detection light 24 at the bottom is turned on. The detection light 24 is made to be in a diffused state by the control screen to detect the turbidity of the water in the optical detection chamber 13. When adjusted to a long-wavelength state, the solubility of specific substances in the water sample is determined by adjusting the specific wavelength. In fluorescence mode, the fluorescence emitted by the substance under laser irradiation is analyzed to detect specific components in the water sample based on the fluorescence characteristics of different substances. The water sample in the optical detection chamber 13 flows out from the side extension tube 23 and falls from the drip hole into the colorimetric cell. Different chemical reagents are added to the colorimetric cell to detect the content of different substances in the water.
[0036] As a further embodiment of the present invention, the oxygen content detection component includes a rotating seat 15 and a COD detector. The COD detector is fixedly installed at the bottom of the mounting groove 6, and the rotating seat 15 is rotatably installed in the mounting groove 6. The lower end of the rotating seat 15 is fixedly connected to the COD detector through a connecting hose. A guide seat is provided at the upper end of the rotating seat 15, and an inlet tube 21 is snapped into the upper end of the guide seat. The sample in the inlet tube 21 can enter the COD detector through the rotating seat 15 and the connecting hose.
[0037] During operation, the rotating seat 15 of this invention rotates, causing the sample in the inlet tube 21 to fall into the connecting hose, and then enters the COD detector through the connecting hose, where the COD detector detects the oxygen demand of the water.
[0038] As a further embodiment of the present invention, the feeding assembly includes a side mounting plate 26, which is fixedly mounted on the upper surface of the mounting groove 6 on one side of the rotating seat 15. A rotating component 18 is rotatably mounted on the side mounting plate 26. A rotating motor 19 is fixedly mounted on the end of the rotating component 18 away from the side mounting plate 26. A connecting frame 20 is fixedly mounted on the output end of the rotating motor 19. A clamping component 17 is fixedly mounted on the end of the connecting frame 20 away from the rotating motor 19. The clamping component 17 can clamp and fix the inlet tube 21. The connecting frame 20 can extend and retract to drive the clamping component 17 away from and towards the rotating component 18.
[0039] During operation, the water sample is placed into the inlet tube 21, which is fixed in the clamping member 17. The rotating member 18 and the connecting frame 20 can drive the inlet tube 21 on the clamping member 17 to move, thereby adjusting the position of the inlet tube 21. The rotating member 18 rotates to adjust the position of the rotating motor 19. At the same time, the rotating motor 19 drives the connecting frame 20 to rotate, thereby driving the clamping member 17 to rotate. The rotation of the clamping member 17 drives the inlet tube 21 to rotate around the upper end of the rotating member 18, while the connecting frame 20 extends to drive the inlet tube 21 to move away from and closer to the rotating member 18.
[0040] As a further embodiment of the present invention, a storage tank 7 is fixedly installed on one end of the mounting groove 6 corresponding to the colorimetric cell 12. An output nozzle 8 is fixedly installed on the side of the storage tank 7 near the side mounting plate 26. A sensor 9 is fixedly installed on the outer surface of the storage tank 7 below the output nozzle 8. When the feeding component drives the inlet tube 21 to approach the output nozzle 8, the chemical reagent in the storage tank 7 will automatically flow out from the output nozzle 8 and into the inlet tube 21. A snap-fit seat 16 is provided between the side mounting plate 26 and the storage tank 7. A snap-fit groove 22 is provided on the snap-fit seat 16. The snap-fit groove 22 fits with the inlet tube 21. A connecting seat 25 is provided between the snap-fit seat 16 and the rotating seat 15. The inlet tube 21 can be snapped onto the upper end of the connecting seat 25.
[0041] During operation, the position of the inlet tube 21 is adjusted by the feeding component, thereby adjusting the position of the inlet tube 21 and the storage tank 7. The feeding component adjusts the inlet tube 21 to the position of the storage tank 7 containing the specified chemical reagent. When the inlet tube 21 approaches the sensor 9, the corresponding chemical reagent in the storage tank 7 automatically falls into the inlet tube 21. The chemical reagent mixes with the water sample in the inlet tube 21. After the sample in the inlet tube 21 is mixed, the feeding component drives the inlet tube 21 to rotate onto the connecting seat 25, and the rotating seat 15 rotates closer to the connecting seat 25. After the inlet tube 21 is engaged with the connecting seat 25, the lower end automatically embeds into the guide seat of the rotating seat 15. This avoids the trouble of manually carrying measuring instruments for water quality testing. The quantitative reagent is output through the storage tank 7, avoiding the trouble of manually adjusting the sample dosage, reducing the number of instruments required for on-site testing, and improving testing efficiency.
[0042] As a further embodiment of the present invention, the electrode detection assembly includes a traction wire 10, one end of which is connected to the inside of the detector body 1, and the other end is led out from the upper end of the detector body 1 and fixedly installed with a detection electrode 11. The detection electrode 11 can be pulled into the optical detection box 13.
[0043] When the metal element content needs to be detected in this invention, the traction line 10 can be pulled out and the detection electrode 11 can be placed in the optical detection box 13. The detection electrode 11 is driven by the control screen 4, so that the metal element flows between the electrodes to complete the detection of the metal element quantity.
[0044] As a further embodiment of the present invention, a movable cover 3 is fixedly installed on the main body 1 of the detector at the position corresponding to the mounting groove 6. The movable cover 3 can rotate to cover the upper end of the mounting groove 6. Holding parts 2 are fixedly installed on both sides of the main body 1 of the detector.
[0045] During operation, the movable cover 3 allows for the detection of the equipment within the mounting slot 6, thereby protecting the equipment. The holding member 2 facilitates the handling of the equipment.
[0046] As a further embodiment of the present invention, each of the output nozzles 8 is provided with a control valve, which is electrically connected to the control panel 4. The control panel 4 can control the output amount flowing out of the storage tank 7 by operating the control valve. The lower end of the control panel 4 is rotatably connected to the mounting base 5, and the mounting base 5 is fixedly installed on the upper surface of the detector body 1.
[0047] During operation, the present invention uses a control valve and a control panel 4 to control the dose in the inlet tube 21, thus avoiding the trouble of dose adjustment.
[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
