[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0031] Please refer to Figures 1-10 , the present invention provides a technical solution: a portable COD determination device for calibrating an on-line monitoring device in a marine environment, including a COD detector 1. The COD detector 1 is selected as an HX-L portable multi-parameter water quality detector. The specific structure is the prior art and will not be elaborated. The COD detector 1 is light and easy to carry. When calibrating the on-line monitoring device in the marine environment, the data obtained by using the COD detector 1 is compared with the data obtained by the on-line monitoring device in the marine environment, and the error of the data of the on-line monitoring device in the marine environment can be obtained. The on-line monitoring device in the marine environment can be adjusted in real time based on the error. The lower installation box 2 and the filter box 9 are fixedly installed on the COD detector 1. The lower installation box 2 is provided with:

[0032] A drawing component, the drawing component is slidably connected in the lower installation box 2 and can be pulled out to be on one side of the lower installation box 2, and one side of the drawing component can be clamped with one side of the lower installation box 2;

[0033] A foldable storage rack, the foldable storage rack is rotatably arranged on the drawing component, and a plurality of placing boards 14 are arranged on the foldable storage rack. When the foldable storage rack is in a folded state, the plurality of placing boards 14 are vertically stacked, and when in an unfolded state, the plurality of placing boards 14 are distributed in a stepped and scattered manner;

[0034] A seawater filtering component is arranged in the filter box 9, and the filter box 9 can filter and collect seawater.

[0035] During operation, the experimental instruments required for water body monitoring are stored in the lower mounting box 2 at the bottom of the COD detector 1 in the present invention. During the actual experiment, the experimental instruments are pulled out of the lower mounting box 2 through the pulling assembly, and then the foldable storage rack is opened. The foldable storage rack forms a stepped operation rack on the pulling assembly, so that the experimental instruments in the lower mounting box 2 can be evenly and stably distributed on this operation rack, providing a stable experimental operation environment for the staff at the water sample collection site, facilitating the user to timely conduct water sample monitoring at any location, also avoiding the trouble of low-temperature storage and then transporting to the laboratory after collecting water samples in the past, reducing the detection steps, reducing the detection cost, and the experimental instruments can be transported and carried along with the whole COD detector 1, avoiding the trouble of the user having to carry multiple sets of equipment for outdoor detection. In the present invention, the collected seawater is poured into the filter box 9, and the filter box 9 removes impurities such as floating objects in the seawater, and then the filtered seawater is used as the water quality monitoring sample to ensure that the collected water body can be used as a sample. After the sample is collected, the sample processing, sample debugging, and colorimetric detection can all be completed by the single device of the present invention.

[0036] As a further solution of the present invention, the filter box 9 is fixedly installed on one side of the COD detector 1. A plurality of filter plates 24 are fixedly installed in the filter box 9. The filter plates 24 are inclined. On one side of the upper surface of the filter box 9 corresponding to the upper end of the filter plates 24, a liquid inlet hopper 8 is fixedly installed. The bottom of the filter box 9 is threadedly connected with a water receiving bottle 17.

[0037] During operation, the collected seawater in the present invention enters the filter box 9 through the liquid inlet hopper 8. After the seawater enters the filter box 9, the seawater passes through a plurality of filter plates 24 in sequence and then falls to the bottom of the filter box 9. The seawater removing floating objects and other impurities at the bottom of the filter box 9 automatically flows into the water receiving bottle 17. The qualified seawater sample can be taken by removing the water receiving bottle 17, and the water receiving bottle 17 is placed on the foldable storage rack for subsequent experiments.

[0038] As a further solution of the present invention, the lower mounting box 2 is fixedly installed on the lower surface of the COD detector 1. A plurality of connecting frames 5 are fixedly installed between the rear side of the lower mounting box 2 and the filter box 9. A handle groove is provided at the bending position of the connecting frame 5.

[0039] During operation, the device in the present invention can be held through the connecting frame 5. During the holding process, the side far from the connecting frame 5 is at the lower end. When the foldable storage rack is folded, the upper end of the reagent bottle is at one end of the connecting frame 5. In this way, when holding the connecting frame 5 to transport the device, the bottom of the reagent bottle on the foldable storage rack automatically is at the lower end.

[0040] As a further solution of the present invention, the pulling component includes a sliding bottom plate 23. An activity cover plate 10 is fixedly installed on the front side of the sliding bottom plate 23. A plurality of clamping grooves are formed on the side of the activity cover plate 10 close to the lower installation box 2. Clamping blocks are arranged at positions corresponding to the clamping grooves on the lower installation box 2, and the clamping blocks fit with the clamping grooves.

[0041] During operation, through the clamping grooves and clamping blocks on the activity cover plate 10, the activity cover plate 10 can be connected and fixed to the lower installation box 2, so as to prevent the activity cover plate 10 from detaching from the lower installation box 2 under the action of gravity when the device is held through the connecting frame 5.

[0042] As a further solution of the present invention, the foldable storage rack includes a rotating member 15 and a connecting member 18. The lower ends of the rotating members 15 are rotatably connected to the sliding bottom plate 23 through rotating shafts 20. Three groups of rotating members 15 are arranged on the same side of the sliding bottom plate 23. The sizes of the three groups of rotating members 15 gradually decrease from the side close to the activity cover plate 10. A connecting member 18 is rotatably connected between adjacent rotating members 15. The upper ends of the rotating members 15 are fixedly connected to the placement plate 14. A fixed box 13 is fixedly installed on the side of the sliding bottom plate 23 close to the activity cover plate 10. A storage drawer 12 is slidably connected in the fixed box 13. The storage drawer 12 can be pulled out through the activity cover plate 10, and pipettes can be placed in the storage drawer 12.

[0043] During operation, in the present invention, the sliding bottom plate 23 is pulled out from the lower installation box 2. After being pulled out, the rotating member 15 close to the activity cover plate 10 is rotated, and the placement plate 14 on the rotating member 15 is rotated to a horizontal state. Due to the connecting member 18 rotatably connected between the rotating members 15, when one group of rotating members 15 is pulled, the other two groups of rotating members can rotate synchronously. After rotation, the three placement plates 14 are distributed in a staggered manner, and chemical reagents, test tubes, etc. on the placement plates 14 are evenly distributed on the storage rack, which is convenient for users to take. When preparing contrast color reagents, the user takes liquid samples through the pipette in the storage drawer 12. After the experiment is completed, the outer rotating member 15 is rotated in the reverse direction until the placement plate 14 returns to the vertical state, and the multiple placement plates 14 are stacked up and down. The reagents, etc. on the placement plate 14 are arranged in layers up and down. At this time, the reagents and test tubes are fixedly clamped on the placement plate 14, avoiding displacement and relative shaking of the reagents and test tubes and other utensils during the movement process, and reducing the collision between the utensils.

[0044] As a further solution of the present invention, limiting rods 19 are arranged on both sides of the sliding bottom plate 23 corresponding to the two sides of the rotating shaft 20. Side mounting plates 11 are fixedly installed on both sides of the sliding bottom plate 23. The two ends of the rotating shaft 20 are rotatably connected to the side mounting plates 11. Locking members 3 are arranged on both sides of the lower mounting box 2. A plug plate 4 is slidably connected inside the locking member 3. Pressing the upper end of the locking member 3 can drive the plug plate 4 to slide into the lower mounting box 2. When the foldable storage rack is folded, the plug plate 4 abuts against one side of the storage plate 14 close to the movable cover plate 10.

[0045] During operation, after the foldable storage rack of the present invention is folded, it is transported into the lower mounting box 2 through the sliding bottom plate 23. Then, by pressing the locking member 3, the plug plate 4 inside the locking member 3 is inserted into the lower mounting box, so that the plug plate 4 abuts against the rear side of the storage plate 14, thereby fixing the position of the storage plate 14 in the lower mounting box 2 and increasing the stability of the storage plate 14 when it is in the lower mounting box 2.

[0046] As a further solution of the present invention, an embedding block 21 and an embedding groove 22 are respectively arranged on both sides of the storage plate 14. Magnetic blocks are arranged inside the embedding block 21 and the embedding groove 22. When the foldable storage rack is folded, multiple groups of storage plates 14 are vertically distributed. At this time, the embedding block 21 of the storage plate 14 is at its lower side. Multiple groups of storage grooves are arranged on the storage plates 14. Sampling tubes for detection can be placed on the uppermost storage plate 14, and multiple groups of detection reagents can be placed on the two lower storage plates 14.

[0047] During operation, when the storage plates 14 of the present invention are vertically distributed, the adjacent storage plates 14 are connected to each other through the magnetic blocks of the embedding block 21 and the embedding groove 22, so that the connection between the storage plates 14 is more stable.

[0048] As a further solution of the present invention, a control screen 7 is fixedly installed on the upper surface of the cod detector 1. A guide seat 6 is arranged on one side of the cod detector 1 corresponding to the control screen 7. A rotating cover 16 is rotatably arranged on the guide seat 6.

[0049] During operation, after the prepared inspection sample and reagent are mixed in a test tube in the present invention, the test tube is inverted and installed on the guide seat 6, and then the cod detector 1 is controlled through the control screen 7 to perform colorimetric detection of the water quality.
