[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-5 An embedded water COD detection device is shown, including an embedded water COD detector 1 and a protective frame 2 located outside the embedded water COD detector 1. The surface of the embedded water COD detector 1 is provided with a detection area 3, and a display screen 4 is provided on one side of the detection area 3.

[0023] Specifically, in this structure, the embedded water COD detector 1 can be stored inside the protective frame 2 for protection when not in use, to avoid being affected by collisions or dust. When in use, it can be pulled out from inside the protective frame 2 without affecting its use.

[0024] The detection area 3 on the surface of the embedded water COD detector 1 can be used to detect COD in water samples. The detection results are displayed on the screen 4. The specific detection principle is existing technology and will not be explained in detail here.

[0025] A movable plate 5 is slidably disposed on one side of the inner cavity of the protective frame 2, and a sealing plate 6 is disposed on the outer wall of the protective frame 2. The embedded water COD detector 1 is fixedly installed between the movable plate 5 and the sealing plate 6. A tension structure is provided at the connection between the sealing plate 6 and the protective frame 2. A wiping structure for cleaning the display screen 4 is provided on the surface of the protective frame 2.

[0026] Specifically, in this structure, when the embedded water COD detector 1 inside the protective frame 2 is moved out for use, the operator can pull the sealing plate 6 to one side, so that the sealing plate 6, through the tensioning structure, drives the embedded water COD detector 1 to extend out from inside the protective frame 2, and the moving plate 5 slides and guides inside the protective frame 2. Conversely, the embedded water COD detector 1 can be stored inside the protective frame 2 for protection after use.

[0027] During the process of pulling out or storing the embedded water COD detector 1 inside the protective frame 2, the display screen 4 on its surface can be wiped clean through the wiping structure, making it convenient for operators to clearly view the values ​​and for the next use.

[0028] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, the tension structure includes first support blocks 7 fixedly installed on both sides of the outer wall of the sealing plate 6. One end of each of the two first support blocks 7 is fixedly provided with a lead screw 8, and one end of the lead screw 8 is fixedly provided with a blocking block 9. Both sides of the outer wall of the protective frame 2 are fixedly installed with second support blocks 10, and the second support blocks 10 are slidably connected to the lead screw 8. Locking nuts 11 are provided on both sides of the lead screw 8 and on both sides of the second support blocks 10. Both locking nuts 11 are threadedly connected to the lead screw 8.

[0029] Specifically, in this structure, when the embedded COD detector 1 extends from inside the protective frame 2, the operator pulls the sealing plate 6 to one side. The sealing plate 6 moves the lead screw 8 via two first support blocks 7, causing the second support block 10 to slide outside the lead screw 8. At this time, the sealing plate 6 causes the embedded COD detector 1 to extend from inside the protective frame 2 to perform water detection. This state is shown in the attached figure. Figure 2 As shown;

[0030] When the embedded COD detector 1 is not in use, push the sealing plate 6 in the reverse direction to retract the embedded COD detector 1 into the protective frame 2. At the same time, by rotating the two locking nuts 11 on the external threads of the screw 8, the second support block 10 is moved left and right to lock, preventing the second support block 10 from sliding unnecessarily on the outside of the screw 8. This state is as shown in the attached figure. Figure 1 As shown.

[0031] In this embodiment, as shown in the appendix Figure 3 , 4 As shown, guide grooves 12 are provided on both sides of the inner wall of the protective frame 2, and guide blocks 13 are fixedly installed at both ends of the movable plate 5. The guide blocks 13 are slidably connected inside the guide grooves 12.

[0032] Specifically, in this structure, when the movable plate 5 slides inside the protective frame 2, it can drive the guide block 13 to slide inside the guide groove 12, thereby guiding the sliding of the movable plate 5 and preventing the movable plate 5 from completely detaching from the inside of the protective frame 2.

[0033] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 1 and 3, the outer wall of the sealing plate 6 is provided with a groove 14, and the surfaces of the movable plate 5 and the protective frame 2 are provided with through holes for the power cord of the embedded water COD detector 1 to pass through.

[0034] Specifically, in this structure, the groove 14 can be used to facilitate the operator to pull the sealing plate 6, while the through hole can be used to easily pass through the power cord of the embedded water COD detector 1 without affecting the normal use of the embedded water COD detector 1.

[0035] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 4 and 5, the wiping structure includes an adjustment plate 15, which is located inside the protective frame 2 and directly above the display screen 4. A cleaning cotton 16 is detachably installed at the bottom of the adjustment plate 15. An adjustment screw 17 and a guide rod 18 are connected to the top of the adjustment plate 15. The adjustment screw 17 is located on one side of the guide rod 18. The adjustment screw 17 is threadedly connected to the protective frame 2, and the guide rod 18 is slidably connected to the protective frame 2. Two T-shaped slots 19 are opened on the lower surface of the adjustment plate 15. A T-shaped block 20 is fixedly installed on the surface of the cleaning cotton 16. The T-shaped block 20 slides and engages inside the T-shaped slots 19.

[0036] Specifically, in this structure, when it is necessary to wipe the display screen 4 of the embedded water COD detector 1, the operator can rotate the adjusting screw 17 to move the adjusting plate 15 towards the display screen 4 of the embedded water COD detector 1 under the guidance of the guide rod 18, and make the cleaning cotton 16 adhere to the surface of the display screen 4. Then, as the embedded water COD detector 1 is pulled out from the protective frame 2 or stored in the protective frame 2, the dust on the surface of the display screen 4 can be wiped by the cleaning cotton 16, which is convenient for use.

[0037] The cleaning cotton 16 can be detached from the adjustment plate 15 via the T-shaped clip 20 and the T-shaped slot 19, making it convenient to disassemble and clean the cleaning cotton 16.

[0038] Working principle of this utility model:

[0039] This application provides an embedded water COD detection device. In the initial state, the embedded water COD detector 1 is housed inside the protective frame 2, the moving plate 5 is inside the protective frame 2, the sealing plate 6 is attached to the protective frame 2, and the locking nut 11 on the screw 8 locks the second support block 10, thereby protecting the detector and preventing it from being affected by collisions and dust.

[0040] In use, the operator pulls the sealing plate 6 through the groove 14 on the sealing plate 6. The sealing plate 6 drives the first support block 7 and the lead screw 8 to move, so that the second support block 10 slides on the lead screw 8. At the same time, the guide blocks 13 at both ends of the moving plate 5 slide along the guide groove 12 on the inner wall of the protective frame 2, guiding the detector to be pulled out smoothly from the protective frame 2. If it is necessary to clean the display screen 4 during the pulling process, the adjusting screw 17 can be rotated to let the adjusting plate 15 move down under the guidance of the guide rod 18, so that the cleaning cotton 16 fits against the surface of the display screen 4. As the detector is pulled out, the cleaning cotton 16 wipes the display screen 4.

[0041] After the detector is pulled out, the second support block 10 is locked in place by locking nut 11 to prevent it from sliding. At this time, the operator places the pretreated water sample in the detection area 3, and the detector performs COD detection. The result is displayed on the display screen 4.

[0042] After the test is completed, push the sealing plate 6 in the reverse direction and the detector is stored back in the protective frame 2. During the storage process, the cleaning cotton 16 wipes the display screen 4 again. If the cleaning cotton 16 needs to be replaced, it can be slidably disassembled and installed through the T-shaped card block 20 and the T-shaped card slot 19 on the adjustment plate 15 for easy cleaning or replacement.

[0043] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
