[0040] The material rack 8 comprises a No. 1 ring body 10 rotatably connected in the rotating tank 7, and a plurality of test tube seats 11 for placing the test tubes 9 are arranged on the No. 1 ring body 10;

[0041] In this embodiment, the designed water quality detector uses the principle of spectrophotometry to detect the quality of sewage. When light of a specific wavelength passes through the sewage sample, various components in the sewage will absorb a certain amount of light. The water quality detector measures the intensity of the transmitted light and calculates the concentration of the corresponding components in the sewage according to the Beer-Lambert law. It can detect various water quality indicators such as COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals (copper, chromium, zinc, etc.), disinfectants (residual chlorine, chlorine dioxide, etc.), and conventional water quality parameters (turbidity, color, dissolved oxygen, etc.). The operation platform 3 is equipped with an intelligent operation system and has a large capacity storage, supporting data export and cloud platform upload functions. The observation platform 4 is equipped with a high-definition touch screen for real-time observation of the detection results.

[0042] The specific operation of the sewage continuous detection equipment is as follows. First, the collected multiple sewage samples are transferred to the test tubes 9 by the pipette. Then, the detection reagent is added to the test tubes 9. After that, the test tubes 9 are placed in the test tube seats 11 on the first ring body 10. Then, the first ring body 10 is moved to transfer all the test tubes 9 to the rotating groove 7. The first ring body 10 can make circular motion in the rotating groove 7. When a certain test tube 9 rotates to the position opposite to the water quality detector probe 6, the rotation of the first ring body 10 is paused. Then, the water quality detector probe 6 starts to detect the sewage in the test tube 9. After the detection is completed, the rotation of the first ring body 10 is continued, and the next test tube 9 rotates to the position opposite to the water quality detector probe 6 for sewage detection. The subsequent test tubes 9 are processed according to the above steps to realize continuous detection of the sewage samples. The connection between the first ring body 10 and the rotating groove 7 is detachable, i.e., the first ring body 10 can be removed. Multiple first ring bodies 10 are set up, and the test tubes 9 are installed on the first ring bodies 10 in advance. After the continuous detection of the samples on the previous first ring body 10 is completed, the first ring body 10 is removed, and then the first ring body 10 with the prepared test tubes 9 is installed directly. This can continuously detect batches of sewage samples. Compared with the existing method of loading, detecting, and unloading each test tube 9 one by one, the sewage continuous detection equipment 1 in this embodiment has higher detection efficiency.

[0048] A plurality of test tube seats 11 are arranged on the upper end surface of the first ring body 10, and the test tube seat 11 is in a cylindrical shape, so that the glass test tube 9 can be wrapped and protected, for example, during the process of transferring the sewage sample into the test tube 9, the test tube 9 can be placed in the test tube seat 11 in advance, and the test tube 9 is clamped and stabilized by the elastic sheet 21, and the plug 19 arranged at the bottom of the test tube seat 11 is inserted into the notch 18, at this time, a plurality of test tubes 9 are placed in a circumferential array on the first ring body 10, and then the sewage sample and the detection reagent are transferred into the test tube 9 one by one by using a pipette, so as to avoid spilling of the sample outside the test tube 9 and reduce the possibility of rolling of the test tube 9; the symmetrical elastic sheets 21 arranged in the test tube seat 11 can clamp test tubes 9 with different diameters and stabilize test tubes 9 with different heights, and the adaptability is stronger.

[0049] With reference to Figures 1-13 A second ring body 22 is arranged on the upper end of the test tube seat 11, a plurality of accommodation holes 23 are formed in a circumferential array on the second ring body 22, and a plurality of groups of insertion rods 24 are arranged in a circumferential array on the lower end surface of the second ring body 22; a anti-disengagement portion 25 is symmetrically arranged on the outer circle of the upper end of each test tube seat 11, a through hole 26 adapted to the insertion rod 24 is formed in each anti-disengagement portion 25, the second ring body 22 is arranged on the upper end of the test tube seat 11, the upper end of the test tube 9 penetrates through the accommodation hole 23, and the insertion rod 24 is inserted into the through hole 26.

[0050] After the detection reagent is dropped into the test tube 9, the test tube 9 needs to be shaken to fully mix the sewage sample and the reagent; the test tube 9 is placed in the test tube seat 11, the test tube seat 11 is installed on the first ring body 10, then the second ring body 22 is installed on the test tube seat 11, the upper end of the test tube 9 penetrates through the accommodation hole 23, the insertion rod 24 is inserted into the through hole 26 on the anti-disengagement part 25, at this time the second ring body 22 is connected with the plurality of test tube seats 11 as a whole, then the first ring body 10 and the second ring body 22 are gripped and pressed on the test tube seat 11, then the plurality of test tubes 9 are shaken as a whole to uniformly mix the sewage sample and the detection reagent, the plurality of test tubes 9 can be concentrated to be shaken, the efficiency is improved, and after the first ring body 10 is placed in the rotating groove 7, the second ring body 22 also sits in the rotating groove 7, then the servo motor is driven, the servo motor drives the outer gear ring 12 to alternately rotate clockwise and counterclockwise, and the plurality of test tubes 9 can also be simultaneously swung to mix the sewage sample and the detection reagent in the test tube 9, and after the mixing is completed, the servo motor drives the outer gear ring 12 to intermittently rotate clockwise or counterclockwise to detect the sewage sample in the test tube 9 one by one.

[0051] With reference to Figures 8-15 , a plurality of support columns 27 are arranged in the circumferential direction of the upper end face of the second ring body 22, a support hole 28 is formed in the upper end face of each support column 27, the positioning pins 16 of the upper material racks 8 are inserted into the support holes 28 on the lower second ring body 22.

[0052] When the sewage sample is prepared outside the sewage continuous detection equipment, the plurality of test tubes 9 can be stacked in the up-down direction, the test tubes 9 are placed in the test tube seats 11 on the lower layer one by one, then the second ring body 22 is installed on the upper end of the test tube seat 11 on the lower layer, then the first ring body 10 on the second layer is placed on the second ring body 22 on the first layer, that is, the positioning pins 16 are embedded in the support holes 28, then the test tube seat 11 and the test tube 9 are placed on the first ring body 10 on the second layer, and so on, the test tubes 9 are stacked layer by layer, and the state shown in Figure 14 and Figure 15 is formed. The stacking structure can stack the test tubes 9 to be detected together or stack the test tubes 9 that have been detected together, so that the space is saved and the operation space occupied by the sewage sample is reduced; when the first ring body 10 is placed in the rotating groove 7, the upper first ring body 10 on the upper layer can be directly placed in the rotating groove 7, and the operation is convenient.

[0053] With reference to Figures 11-13 , a sliding hole 29 is symmetrically formed in the outer circle of the upper end of each test tube seat 11, the sliding hole 29 is close to the anti-disengagement part 25, the lower end of each spring piece 21 in each test tube seat 11 is fixed to the inner bottom of the test tube seat 11, and the upper end of each spring piece 21 is inclined to penetrate through the sliding hole 29 to the lower side of the through hole 26.

[0054] The upper end of the elastic sheet 21 is in a free state, and during the insertion of the lower end of the test tube 9 into the test tube seat 11, the lower end of the test tube 9 can expand the elastic sheet 21 outward, so that the elastic sheet 21 adapts to the diameter of the test tube 9, and when the second ring body 22 is installed on the test tube seat 11, the insertion rod 24 is inserted into the through hole 26, and the outer circle of the insertion rod 24 extrudes the upper end of the elastic sheet 21, at this time, the extrusion force of the upper end of the elastic sheet 21 on the outer wall of the test tube 9 is increased, which can further improve the extrusion stability of the elastic sheet 21 on the test tube 9. In order to ensure the fit between the elastic sheet 21 and the test tube 9, a rubber layer can be provided on the surface of the elastic sheet 21, which can improve the extrusion effect of the elastic sheet 21 on the test tube 9 and further improve the stability of the test tube 9 in the test tube seat 11.

[0055] Referring to Figures 10-13 Each of the insertion rods 24 is provided in a circular truncated cone shape, and a radially arranged annular groove 30 is formed in the outer circle of the bottom of each insertion rod 24. When the insertion rod 24 is inserted into the through hole 26, the upper end of the elastic sheet 21 slides along the outer circle of the lower end of the insertion rod 24 and slides into the groove 30, and the groove 30 extrudes the upper end of the elastic sheet 21.

[0056] When the insertion rod 24 is inserted into the through hole 26, the upper end of the elastic sheet 21 slides along the outer circle of the insertion rod 24 and slides into the groove 30, and the upper end of the elastic sheet 21 is clamped into the groove 30, thereby restraining the relative sliding between the insertion rod 24 and the through hole 26, that is, the second ring body 22 is restrained on the test tube seat 11. When multiple test tubes 9 are shaken at the same time, the second ring body 22 is also difficult to separate from the test tube seat 11, thereby improving the safety of the test tubes 9, and the groove 30 also restrains the elastic sheet 21, so that the elastic sheet 21 can be firmly extruded on the test tube 9, and the insertion rod 24 and the elastic sheet 21 complement each other.

[0057] Referring to Figures 3-15 An iron block is arranged in each of the notches 18 and the inner bottom of each of the support holes 28; each of the insertion pins 19 is made of a magnetic material capable of adsorbing the iron block;

[0058] The first ring body 10, the second ring body 22 and the test tube seat 11 are all made of plastic material, which is relatively light, facilitating shaking of multiple test tubes 9. Iron blocks are arranged in each notch 18 and each supporting hole 28. The iron blocks are matched with the latches 19 capable of adsorbing the iron blocks. When the test tube seat 11 is installed on the first ring body 10, the latches 19 are fixed in the notches 18 by adsorption. Meanwhile, the iron blocks are also fixed in each positioning groove 15. The lower end face positioning pin 16 of the first ring body 10 is also made of a magnetic material capable of adsorbing the iron blocks. When the first ring body 10 is installed on the outer tooth ring 12, the positioning pin 16 is embedded in the positioning groove 15 and adsorbs the iron blocks, improving the stability between the first ring body 10 and the outer tooth ring 12. When the servo motor drives the first ring body 10 to rotate clockwise and counterclockwise intermittently, the first ring body 10 can still be stably arranged on the outer tooth ring 12. Meanwhile, when the upper and lower multiple test tubes 9 are stacked, the positioning pin 16 of the upper first ring body 10 is embedded in the supporting hole 28 of the lower second ring body 22, which can improve the stability between the adjacent first ring body 10 and second ring body 22, so that the stacked test tubes 9 can be stably arranged.

[0059] With reference to Figures 1-3 Two of the detection devices 1 are provided with protective plates 31. One of the protective plates 31 is fixed on the bottom plate 2, and the other protective plate 31 is magnetically adsorbed on the outer sidewalls of the two operation tables 3. The upper edge of one of the protective plates 31 is rotatably connected with a cover plate 32, which is used to cover the detection device 1 and the test tube 9.

[0060] The protective plate 31 is used to shield the influence of external light on the light of the water quality detector probe 6. The water quality detector probe 6 detects the sewage sample by the principle of spectrophotometry, and needs to be detected in a certain light-shielded condition. For example, in a laboratory, the light is not sufficient, and the detection can be directly performed. If the operation is performed outdoors, the light is sufficient, and the detection needs to be performed by shielding the light through the protective plate 31. The cover plate 32 is rotated and opened, and then the other protective plate 31 is removed. Since the other protective plate 31 is magnetically adsorbed on the operation table 3, the protective plate 31 can be directly removed. Then the first ring body 10 is placed, and then the other protective plate 31 is installed and reset, and the cover plate 32 is rotated and covers above the test tube 9, so that the entire sewage continuous detection device is covered, and the sewage detection is performed.

[0061] With reference to Figure 11 Each of the elastic sheets 21 is arranged in an arc shape with the pressing surface of the test tube 9. The shape of the elastic sheet 21 enables the elastic sheet 21 to further adhere to the surface of the test tube 9, and further improves the clamping effect of the elastic sheet 21 on the test tube 9, and further improves the stability of the test tube 9 in the test tube seat 11.

[0062] Working principle: first, the test tube 9 is embedded in the test tube seat 11 one by one, and then the test tube seat 11 is connected with the test tube 9 and installed on the first ring body 10. The specific test tube seat 11 bottom pin 19 is inserted into the notch 18, and the pin 19 is adsorbed and fixed on the iron block arranged in the notch 18 by adsorption. Then, the sewage sample is dropped into each test tube 9 by using a pipette, and then the detection reagent is dropped. Then, each test tube 9 is blocked by the test tube 9 plug one by one. Finally, the second ring body 22 is installed, the plug rod 24 is inserted into the through hole 26, the outer circle of the plug rod 24 extrudes the upper end of the spring piece 21, the spring piece 21 further extrudes the test tube 9, and then the first ring body 10 and the second ring body 22 are held with both hands. Shake the test tube 9 up and down or left and right, so that the sewage sample in the test tube 9 is mixed evenly with the detection reagent, and the sewage sample is prepared.

[0063] The prepared sewage sample is placed in the rotating groove 7. The specific positioning pin 16 on the lower surface of the first ring body 10 is embedded in the positioning groove 15 on the outer tooth ring 12. The first ring body 10 rotates synchronously with the outer tooth ring 12, and the outer tooth ring 12 is intermittently driven to rotate by the servo motor controlled by the PLC, so that each test tube 9 is opposite to the water quality detector probe 6. The water quality detector probe 6 detects the sewage sample in the test tube 9 through the detection window 20 on the test tube seat 11.

[0064] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
