Therefore, a feature specified as "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of the features.

[0043] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0044] Reference Figures 1 to 6 As shown, this embodiment provides a water quality detection and cleaning system, including a body 100, a test water tank 200, a cleaning water tank 300, a detection member 400, a scrubbing structure 500, a first position switching module 600 and a second position switching module 700.

[0045] The cleaning water tank 300 and the testing water tank 200 are disposed in the body 100 at intervals along the length direction of the body 100 .

[0046] The first position switching module 600 and the second position switching module 700 are arranged on the body 100, the detection component 400 is arranged in the first position switching module 600, and can be moved into the cleaning water tank 300 under the drive of the first position switching module 600 to clean the detection component 400 or moved into the test water tank 200 to detect the test water in the test water tank 200; the scrubbing structure 500 is arranged in the second position switching module 700, and can be moved into the test water tank 200 under the drive of the second position switching module 700 to scrub the test water tank 200 or moved outside the test water tank 200.

[0047] When implementing it, refer to Figure 1 As shown, the cleaning water tank 300 and the test water tank 200 can be arranged along the length direction of the machine body 100, that is, Figure 1 For example, the cleaning water tank 300 can be located on the left side of the test water tank 200. Alternatively, in other implementations, the cleaning water tank 300 can also be located on the right side of the test water tank 200, which is not specifically limited in this embodiment.

[0048] When the cleaning water tank 300 is located on the left side of the test water tank 200, in order to facilitate the first position switching module 600 to drive the detection component 400 to move into the cleaning water tank 300, the first position switching module 600 and the second position switching module 700 can also be arranged along the left and right directions.

[0049] When it is necessary to perform a water quality test on the test water in the test water tank 200, the second position switching module 700 can drive the scrubbing structure 500 provided thereon to move out of the test water tank 200, so that the first position switching module 600 can drive the detection component 400 provided thereon to move into the test water tank 200, so as to perform a water quality test on the test water in the test water tank 200.

[0050] After the inspection is completed, the first position switching module 600 can be used to drive the inspection member 400 out of the test water tank 200 and into the cleaning water tank 300, so that the inspection member 400 can be cleaned independently without blind spots in the cleaning water tank 300. At the same time, the second position switching module 700 can be used to drive the scrubbing structure 500 into the test water tank 200 to scrub the inner wall of the test water tank 200, thereby achieving independent and comprehensive cleaning of the inspection member 400 and the test water tank 200, thereby improving the cleaning effect.

[0051] When cleaning is completed, the second position switching module 700 can be used to drive the scrubbing structure 500 to move out of the test water tank 200 so as to restore the structure to its initial state for the next water quality testing operation.

[0052] For example, the test water tank 200 and the cleaning water tank 300 may both be cylindrical water tanks or square water tanks.

[0053] It should be noted that during water quality testing, the test water tank 200 contains test water, i.e., the water to be tested. When the test water tank 200 needs to be cleaned, the test water is drained from the test water tank 200 and cleansing water is introduced into the test water tank 200 to facilitate scrubbing and cleaning the inner wall of the test water tank 200 via the scrubbing structure 500. For example, the cleansing water can be tap water.

[0054] Exemplarily, the detection element 400 may be a five-parameter sensor or other water quality detectors.

[0055] That is, the water quality testing and cleaning system of the embodiment of the present invention can, when water quality testing is required, move the scrubbing structure 500 out of the test water tank 200 via the second position switching module 700, and move the detection member 400 into the test water tank 200 via the first position switching module 600 to perform a water quality test on the test water in the test water tank 200. When cleaning is required after the test, the detection member 400 is moved out of the test water tank 200 and into the cleaning water tank 300 via the first position switching module 600, so that the detection member 400 can be cleaned by the cleaning water tank 300. Simultaneously, the scrubbing structure 500 is moved into the test water tank 200 via the second position switching module 700, so that the test water tank 200 can be cleaned by the scrubbing structure 500. This allows for the independent cleaning of the test water tank 200 and the detection member 400 without blind spots, thereby improving the cleaning effect and ensuring the accuracy of subsequent test results.

[0056] In addition, the water quality detection and cleaning system also includes a controller 110, which is electrically connected to the first position switching module 600 and the second position switching module 700 respectively, and is used to control the working status of the first position switching module 600 and the second position switching module 700, thereby realizing automatic control of the above operations.

[0057] Reference Figure 1 As shown, in some embodiments, the first position switching module 600 includes a first track 610 provided on the body 100 and a second track 620 slidably provided on the first track 610. The first track 610 extends along the length direction of the body 100 (refer to FIG. Figure 1 The second rail 620 extends in the up-down direction of the body 100 , and the detection member 400 is slidably disposed on the second rail 620 .

[0058] In a specific implementation, the first track 610 follows Figure 1 The second track 620 extends in the left-right direction as shown. Figure 1 As shown, the second track 620 can slide in the left and right directions relative to the first track 610, and the detection member 400 can slide in the up and down directions relative to the second track 620, so that the detection member 400 can be moved into or out of the test water tank 200 or moved into or out of the cleaning water tank 300.

[0059] For example, the cleaning water tank 300 is located on the left side of the testing water tank 200 , and the first position switching module 600 is located in front of the testing water tank 200 and the cleaning water tank 300 .

[0060] For example, if the initial position state is that the detection part 400 is located in the cleaning water tank 300, the scrubbing structure 500 is located in the test water tank 200, and the water quality of the test water in the test water tank 200 needs to be tested, the scrubbing structure 500 can be driven out of the test water tank 200 through the second position switching module 700.

[0061] The detection member 400 then slides relative to the second rail 620 toward the front and to the front position on the second rail 620. The detection member 400 is now entirely outside the washing water tank 300. The second rail 620 then slides rightward relative to the first rail 610 to the right position on the first rail 610. The second rail 620 then drives the detection member 400 to slide rightward to a position directly opposite the test water tank 200. The detection member 400 then slides rearward relative to the second rail 620 to the rear position on the second rail 620. The detection member 400 is now entirely inside the test water tank 200, facilitating water quality testing of the test water in the test water tank 200.

[0062] After the detection is completed, the detection member 400 can be slid forward relative to the second track 620 to the front position on the second track 620. At this time, the detection member 400 moves out of the test water tank 200, and then the second track 620 moves to the left relative to the first track 610 to the left position of the first track 610. Then the detection member 400 slides backward relative to the second track 620 to the rear position of the second track 620, so that the detection member 400 moves into the cleaning water tank 300, thereby switching the detection member 400 back to the initial position.

[0063] For example, the detection member 400 can be slidably connected to the second rail 620 via a chute or a slide rail. The second rail 620 can be slidably connected to the first rail 610 via a chute or a slide rail. The scrubbing structure 500 can be slidably connected to the fourth rail 720 via a chute or a slide rail. The fourth rail 720 can be slidably connected to the third rail 710 via a chute or a slide rail.

[0064] Reference Figures 1 to 6 As shown, in some embodiments, the first position switching module 600 includes a first driving component and at least four first sensing devices 630 electrically connected to the first driving component. The first driving component is respectively coupled with the second track 620 and the detection member 400 to drive the second track 620 and the detection member 400 to slide.

[0065] At least four first sensing devices 630 are respectively disposed on the first track 610 and the second track 620 , and are used to trigger the first driving assembly to stop driving when the detection member 400 moves into the cleaning water tank 300 or the testing water tank 200 .

[0066] In a specific implementation, the first drive assembly can be used to drive the second track 620 to slide relative to the first track 610 and the detection member 400 to slide relative to the second track 620, thereby achieving automated operation and saving manpower. For example, the first drive assembly can include two first servo motors to drive the second track 620 and the detection member 400 to move respectively.

[0067] Furthermore, in order to enable the second rail 620 to accurately slide to the corresponding left position and right position, two first sensing devices 630 can be set on the first rail 610. The two first sensing devices 630 can be located at the left position and the right position respectively, so that when the second rail 620 slides to the left position or the right position relative to the first rail 610, a touch command is issued through the first sensing device 630 at the left position or the right position to control the first servo motor that drives the second rail 620 to stop driving.

[0068] Similarly, in order to enable the detection member 400 to accurately slide to the corresponding front position and rear position, two first sensing devices 630 can be set on the second track 620. The two first sensing devices 630 can be located at the front position and the rear position respectively, so that when the detection member 400 slides to the front position or the rear position relative to the second track 620, a touch command is issued through the first sensing device 630 at the front position or the rear position to control the first servo motor that drives the detection member 400 to stop driving.

[0069] Reference Figures 1 to 4 As shown, in some embodiments, the second position switching module 700 includes a third track 710 provided on the body 100 and a fourth track 720 slidably provided on the third track 710, the third track 710 extends left and right along the body 100, the fourth track 720 extends up and down along the body 100, and the brushing structure 500 is slidably provided on the fourth track 720.

[0070] In specific implementation, the third track 710 follows Figure 1 The fourth track 720 extends in the left-right direction as shown. Figure 1 The fourth track 720 can slide in the left and right directions relative to the third track 710, and the brushing structure 500 can slide up and down relative to the fourth track 720, so that the brushing structure 500 can be moved into or out of the test water tank 200.

[0071] For example, the cleaning water tank 300 is located on the left side of the testing water tank 200 , and the second position switching module 700 is located in front of the testing water tank 200 and the cleaning water tank 300 .

[0072] For example, if the initial position state is that the detection part 400 is located in the cleaning water tank 300, the scrubbing structure 500 is located in the test water tank 200, and the water quality of the test water in the test water tank 200 needs to be tested, the scrubbing structure 500 can be first moved rearward relative to the fourth track 720 to the rear position. At this time, the scrubbing structure 500 moves out of the test water tank 200, and then the fourth track 720 moves to the right relative to the third track 710 to the right position of the third track 710. At this time, the entire scrubbing structure 500 is located on the outside of the test water tank 200 away from the cleaning water tank 300 to avoid position interference with the detection part 400.

[0073] The detection member 400 then slides relative to the second rail 620 toward the front and to the front position on the second rail 620. The detection member 400 is now entirely outside the washing water tank 300. The second rail 620 then slides rightward relative to the first rail 610 to the right position on the first rail 610. The second rail 620 then drives the detection member 400 to slide rightward to a position directly opposite the test water tank 200. The detection member 400 then slides rearward relative to the second rail 620 to the rear position on the second rail 620. The detection member 400 is now entirely inside the test water tank 200, facilitating water quality testing of the test water in the test water tank 200.

[0074] After the test is completed, the detection member 400 can be slid forward relative to the second track 620 to the front position on the second track 620, at which point the detection member 400 is removed from the test water tank 200. The second track 620 then moves leftward relative to the first track 610 to the left side of the first track 610. The detection member 400 then slides rearward relative to the second track 620 to the rear side of the second track 620, allowing the detection member 400 to move into the cleaning water tank 300. Simultaneously, the fourth track 720 moves leftward relative to the third track 710 to the left side, at which point the scrubbing structure 500 is positioned opposite the test water tank 200. The scrubbing structure 500 then slides rearward relative to the fourth track 720 to the rear side of the fourth track 720, allowing the scrubbing structure 500 to move into the test water tank 200, thereby returning the detection member 400 and scrubbing structure 500 to their initial positions.

[0075] Reference Figure 1 As shown, in some embodiments, the second position switching module 700 includes a second driving component and at least four second sensing devices 730 electrically connected to the second driving component. The second driving component is respectively coupled with the fourth track 720 and the brushing structure 500 to drive the fourth track 720 and the brushing structure 500 to slide.

[0076] At least four second sensing devices 730 are respectively disposed on the third track 710 and the fourth track 720 and are used to trigger the second driving assembly to stop driving when the scrubbing structure 500 moves into or out of the test water tank 200 .

[0077] In a specific implementation, the second drive assembly can be used to drive the fourth track 720 to slide relative to the second track 620 and the brush structure 500 to slide relative to the fourth track 720, thereby achieving automated operation and saving manpower. For example, the second drive assembly can include two second servo motors to drive the fourth track 720 and the brush structure 500 to move respectively.

[0078] Furthermore, in order to enable the fourth rail 720 to accurately slide to the corresponding left position and right position, two second sensing devices 730 can be set on the third rail 710. The two second sensing devices can be located at the left position and the right position respectively, so that when the fourth rail 720 slides to the left position or the right position relative to the third rail 710, a touch command is issued through the second sensing device 730 at the left position or the right position to control the second servo motor that drives the fourth rail 720 to stop driving.

[0079] Similarly, in order to enable the brushing structure 500 to accurately slide to the corresponding front position and rear position, two second sensing devices 730 can be set on the fourth track 720. The two second sensing devices 730 can be located at the front position and the rear position respectively, so that when the brushing structure 500 slides to the front position or the rear position relative to the fourth track 720, a touch command is issued through the second sensing device 730 at the front position or the rear position to control the second servo motor that drives the brushing structure 500 to stop driving.

[0080] Reference Figures 1 to 4 As shown, in some embodiments, the first position switching module 600 and the second position switching module 700 are spaced apart along the length direction of the body 100, and the first position switching module 600 and the second position switching module 700 are both located on the same side of the cleaning water tank 300 and the test water tank 200 along the width direction of the body 100, so as to achieve a compact layout while realizing corresponding position switching operations.

[0081] Reference Figures 1 to 4 As shown, in some embodiments, part of the first position switching module 600 and part of the second position switching module 700 are staggered along the width direction or height direction of the body 100 to avoid interference between the detection member 400 and the brushing structure 500 during position switching.

[0082] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the water quality detection and cleaning system further includes a water supply pipeline assembly 800, which is in communication with the test water tank 200 and the wash water tank 300, respectively, to deliver cleaning water or test water to the test water tank 200 or the wash water tank 300. In this way, when water quality testing is required, test water is provided to the test water tank 200 via the water supply pipeline assembly 800. Furthermore, when cleaning water needs to be stored in the test water tank 200 and the wash water tank 300 for cleaning the test water tank 200 and the detection element 400, the water supply pipeline assembly 800 can stably supply cleaning water to the test water tank 200 and the wash water tank 300.

[0083] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the water supply pipeline assembly 800 includes a first water supply pipeline 801, one end of the first water supply pipeline 801 has a test water inlet 802 for external test water to enter, and the other end of the first water supply pipeline 801 is respectively connected to the test water inlet 802 and the test water tank 200;

[0084] A first control valve 803 and a second control valve 804 are provided in the first water supply pipeline 801 . The first control valve 803 and the second control valve 804 are spaced apart along the extending direction of the first water supply pipeline 801 .

[0085] In a specific implementation, when water quality testing is required, the first control valve 803 and the second control valve 804 are opened, allowing external test water to be sequentially delivered to the test water tank 200 through the test water inlet 802 and the first water supply pipeline 801, thereby achieving the test water supply operation. When the test water supply is not required, the first control valve 803 and the second control valve 804 are closed.

[0086] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the water supply pipeline assembly 800 includes a second water supply pipeline 805, a first sub-pipeline 806, and a second sub-pipeline 807. One end of the second water supply pipeline 805 has a first washing water inlet 808 for external washing water to enter. The other end of the second water supply pipeline 805 is selectively connected to one end of the first sub-pipeline 806 and one end of the second sub-pipeline 807. The other end of the first sub-pipeline 806 is connected to the test water tank 200, and the other end of the second sub-pipeline 807 is connected to the washing water tank 300.

[0087] A third control valve 809 is provided at the intersection of the second water supply pipeline 805 , the first sub-pipeline 806 and the second sub-pipeline 807 .

[0088] In a specific implementation, when cleaning water needs to be supplied to the test water tank 200 for cleaning, the third control valve 809 can be used to control the second water supply line 805 to be connected to the first sub-line 806 while disconnecting the second water supply line 805 from the second sub-line 807. External cleaning water is then sequentially delivered to the test water tank 200 via the first cleaning water inlet 808, the second water supply line 805, and the first sub-line 806, thereby ensuring a reliable supply of cleaning water. When cleaning water is not needed, the third control valve 809 can be used to disconnect the second water supply line 805 from the first sub-line 806.

[0089] Similarly, when it is necessary to supply washing water to the washing water tank 300 to clean the detection element 400, the third control valve 809 can be used to control the second water supply pipeline 805 to be connected to the second sub-pipeline 807 while disconnecting the second water supply pipeline 805 from the first sub-pipeline 806. In this case, external washing water is sequentially delivered to the washing water tank 300 through the first washing water inlet 808, the second water supply pipeline 805, and the second sub-pipeline 807, thereby ensuring a reliable supply of washing water. When it is not necessary to supply washing water, the third control valve 809 can be used to disconnect the second water supply pipeline 805 from the second sub-pipeline 807.

[0090] Alternatively, when it is necessary to supply cleaning water to the test water tank 200 and the cleaning water tank 300 at the same time, the second water supply pipeline 805 can be controlled by the third control valve 809 to be connected to the first sub-pipeline 806 and the second sub-pipeline 807 respectively. The entire structure is simple and easy to operate.

[0091] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the water supply pipeline assembly 800 further includes a third water supply pipeline 810, one end of the third water supply pipeline 810 having a second washing water inlet 811 for external washing water to enter, and the other end of the third water supply pipeline 810 is respectively connected to the second washing water inlet 811 and the washing water tank 300;

[0093] In specific implementation, when it is necessary to supply cleaning water to the cleaning water tank 300 to clean the cleaning water tank 300, the fourth control valve 814 can be used to control the main line 812 and the third water supply line 810 to be connected, so that the external cleaning water can be transported to the cleaning water tank 300 through the main water inlet 813, the second cleaning water inlet 811, and the third water supply line 810 in sequence to clean the cleaning water tank 300.

[0094] In addition, the water supply pipe assembly 800 may further include a water storage tank 910 to provide washing water to the water supply pipe assembly 800 .

[0095] Reference Figure 1 、 Figure 5 and Figure 6As shown, in some embodiments, the water quality detection and cleaning system also includes a drainage pipe assembly 900, which is connected to the test water tank 200 and the cleaning water tank 300 respectively, and is used to discharge the cleaning water or test water in the test water tank 200 and the cleaning water tank 300, so as to quickly realize the drainage operation for subsequent use.

[0096] For example, when the test water tank 200 is filled with test water and needs to be cleaned, the test water in the test water tank 200 can be drained out through the drainage pipe assembly 900 first, and then cleaning water can be delivered to the test water tank 200 through the water supply pipe assembly 800.

[0097] Alternatively, when the test water tank 200 contains cleaning water and a water quality test operation of the test water is required, the cleaning water in the test water tank 200 can be first discharged through the drainage pipe assembly 900, and then the test water can be transported into the test water tank 200 through the water supply pipe assembly 800.

[0098] Similarly, after the cleaning of the cleaning water tank 300 is completed, the cleaning water in the cleaning water tank 300 can be discharged through the drainage pipe assembly 900 to facilitate the next detection and cleaning operation.

[0099] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the drainage pipe assembly 900 includes a main drainage pipe 901, one end of which has a drain outlet 902, and the main drainage pipe 901 is connected to the test water tank 200 and the cleaning water tank 300 respectively, so that the test water tank 200 and the cleaning water tank 300 can share a main drainage pipe to achieve drainage operation, thereby simplifying the structure and reducing costs.

[0100] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the drainage pipe assembly 900 includes at least one first drainage pipe 903 , which is respectively connected to the test water tank 200 and the main drainage pipe 901 , and a fifth control valve 904 is provided in the first drainage pipe 903 .

[0101] That is, when the test water or cleaning water in the test water tank 200 needs to be discharged, the fifth control valve 904 can be opened so that the test water or cleaning water in the test water tank 200 can be discharged through the first drainage pipe 903 and the main drainage pipe 901 in sequence.

[0102] When the discharge operation is completed, the fifth control valve 904 may be closed.

[0103] Furthermore, the first drainage pipe 903 can be configured as follows Figure 1 As shown, two first drain ports 902 can be provided at the bottom and side of the test water tank 200 , respectively, and connected to two first drain pipes 903 , respectively, to achieve drainage operations at different water levels or meet different drainage efficiency requirements.

[0104] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the drainage pipe assembly 900 includes at least one second drainage pipe 905 , which is respectively connected to the cleaning water tank 300 and the main drainage pipe 901 , and a sixth control valve 906 is provided in the second drainage pipe 905 .

[0105] That is, when the washing water in the washing water tank 300 needs to be discharged, the sixth control valve 906 can be opened so that the washing water can be discharged through the second drainage pipe 905 and the main drainage pipe 901 in sequence.

[0106] When the discharge operation is completed, the sixth control valve 906 may be closed.

[0107] Furthermore, the second drainage pipe 905 can be configured as follows Figure 1 As shown, the two second drain ports 902 can be respectively provided at the bottom and the side of the cleaning water tank 300 and connected to the two second drain pipes 905 respectively, so as to realize drainage operations at different water levels or meet different drainage efficiency requirements.

[0108] Reference Figures 1 to 6 As shown, in some embodiments, the water quality detection and cleaning system also includes a flushing water tank 907, which is arranged on the body 100 and is located on the side of the test water tank 200 away from the cleaning water tank 300. The flushing water tank 907 is used to clean the scrubbing structure 500 when the scrubbing structure 500 is moved out of the test water tank 200 and moved into the flushing water tank 907; the drainage pipe assembly 900 also includes at least one third drainage pipe 908, and at least one third drainage pipe 908 is respectively connected to the flushing water tank 907 and the main drainage pipe 901; at least one seventh control valve 909 is provided in the third drainage pipe 908.

[0109] In specific implementation, when the fourth slide rail moves to the right position relative to the third slide rail, the scrubbing structure 500 is arranged opposite to the flushing water tank 907, and then the scrubbing structure 500 can be moved to the rear position relative to the fourth slide rail. At this time, the scrubbing structure 500 is located outside the test water tank, and specifically inside the flushing water tank 907, so as to clean the scrubbing structure 500 to ensure that the scrubbing structure 500 is clean and the next cleaning operation of the test water tank 200 can be carried out.

[0110] Specifically, after the flushing water tank 907 completes the cleaning operation on the scrubbing structure 500 , the seventh control valve 909 can be opened so that the cleaning water can be discharged through the third drainage pipeline 908 and the main drainage pipeline 901 .

[0111] When the discharge operation is completed, the seventh control valve 909 may be closed.

[0112] Furthermore, the third drainage pipe 908 can be configured as follows Figure 1 As shown, the two third drain outlets 902 can be respectively provided at the bottom and side of the flushing water tank 907 and connected to the two third drain pipes 908 respectively, so as to realize drainage operations at different water levels or meet different drainage efficiency requirements.

[0113] Reference Figures 1 to 6 As shown, in some embodiments, the brushing structure 500 can be rotatably arranged in the second position switching module 700, and the brushing structure 500 includes at least one brush body 510 and a stepper motor 502. At least one brush body 510 is used to be driven to rotate by the stepper motor 502 when the brushing structure 500 moves into the test water tank 200, so as to rotationally brush the inner wall of the test water tank 200, thereby achieving dead-angle cleaning at various positions of the inner wall of the test water tank 200.

[0114] Furthermore, the brushing structure 500 also includes a motor, which can drive the brush body 510 to rotate to achieve automatic operation.

[0115] In addition, the number of brush bodies 510 can be three, two of which can extend along the axial direction of the brushing structure 500 , and the other brush body 510 can extend obliquely along the axial direction of the brushing structure 500 , so as to more effectively clean the inner wall of the test water tank 200 .

[0116] Reference Figures 1 to 6 As shown, in some embodiments, the cleaning water tank 300 includes a transparent cleaning box body 310 and a cleaning nozzle provided in the cleaning box body 310, so as to spray and clean the detection part 400 located in the cleaning box body 310 through the cleaning nozzle to improve the cleaning effect.

[0117] In addition, the transparent cleaning box 310 allows the operator to visually observe the cleaning process and cleaning effect of the detection member 400.

[0118] Finally, combine Figure 1 The operation process of the water quality detection and cleaning device of this embodiment is described as follows:

[0119] First, the first control valve 803 and the second control valve 804 are opened, so that the external test water can be transported into the test water tank 200 through the test water inlet 802 and the first water supply pipeline 801 in sequence.

[0120] Then, the brushing structure 500 is moved rearward to a rear position relative to the fourth track 720. At this time, the brushing structure 500 moves out of the test water tank 200. Then, the fourth track 720 moves to the right relative to the third track 710 to the right position of the third track 710. At this time, the entire brushing structure 500 is located on the outside of the test water tank 200 away from the cleaning water tank 300 to avoid positional interference with the detection part 400.

[0121] The detection member 400 then slides relative to the second rail 620 toward the front and to the front position on the second rail 620. The detection member 400 is now entirely outside the washing water tank 300. The second rail 620 then slides rightward relative to the first rail 610 to the right position on the first rail 610. The second rail 620 then drives the detection member 400 to slide rightward to a position directly opposite the test water tank 200. The detection member 400 then slides rearward relative to the second rail 620 to the rear position on the second rail 620. The detection member 400 is now entirely inside the test water tank 200, facilitating water quality testing of the test water in the test water tank 200.

[0122] After the water quality test is completed, the fifth control valve 904 is opened to allow the test water in the test water tank 200 to be discharged sequentially through the first drainage pipe 903 and the main drainage pipe 901. When the discharge operation is completed, the fifth control valve 904 is closed.

[0123] Then, the detection member 400 can be slid forward relative to the second track 620 to the front position on the second track 620, at which time the detection member 400 moves out of the test water tank 200, and then the second track 620 moves left relative to the first track 610 to the left position of the first track 610, and then the detection member 400 slides backward relative to the second track 620 to the rear position of the second track 620, so that the detection member 400 moves into the cleaning water tank 300.

[0124] Next, the second water supply pipeline 805 and the second sub-pipeline 807 are controlled to be connected through the third control valve 809. At this time, the external cleaning water is transported to the cleaning water tank 300 through the first cleaning water inlet 808, the second water supply pipeline 805 and the second sub-pipeline 807 in sequence to achieve a reliable supply of cleaning water, so as to facilitate the cleaning of the detection part 400 in the cleaning water tank 300.

[0125] At the same time, the fourth control valve 814 controls the main line 812 and the third water supply line 810 to be connected, so that the external cleaning water can be transported to the cleaning water tank 300 through the main water inlet 813, the second cleaning water inlet 811, and the third water supply line 810 in sequence to facilitate cleaning of the cleaning water tank 300.

[0126] After cleaning is completed, the cleaning water in the cleaning water tank 300 can be discharged through the second drainage pipe 905 and the main drainage pipe 901.

[0127] At the same time, the fourth track 720 moves leftward relative to the third track 710 to a left position, at which point the scrubbing structure 500 is positioned opposite the test water tank 200. The scrubbing structure 500 then slides rearward relative to the fourth track 720 to a position behind the fourth track 720. The scrubbing structure 500 then moves into the test water tank 200. The third control valve 809 controls the second water supply line 805 to connect with the first sub-line 806 while disconnecting the second water supply line 805 from the second sub-line 807. External cleaning water is then sequentially delivered to the test water tank 200 through the first cleaning water inlet 808, the second water supply line 805, and the first sub-line 806, allowing the scrubbing structure 500 to clean the test water tank 200.

[0128] After cleaning, the cleaning water in the test water tank 200 can be drained through the first drainage pipe 903 and the main drainage pipe 901 .

[0129] After the test water tank 200 is cleaned, the fourth slide rail moves to the right position relative to the third slide rail. At this time, the scrubbing structure 500 is arranged opposite to the flushing water tank 907. Then the scrubbing structure 500 can be moved to the rear position relative to the fourth slide rail. At this time, the scrubbing structure 500 is located in the flushing water tank 907 to clean the scrubbing structure 500 to ensure that the next cleaning operation of the test water tank 200 can be carried out after the scrubbing structure 500 is clean.

[0130] After cleaning, the cleaning water in the flushing water tank 907 can be discharged through the third drainage pipe 908 and the main drainage pipe 901.

[0131] In short, the control process of the water supply pipeline assembly 800 and the drainage pipeline assembly 900 is:

[0132] First, the first control valve 803 and the second control valve 804 are opened to supply water into the test water tank 200 to complete the inflow of test water into the test water tank 200 for water quality testing.

[0133] After the test is complete, the fifth control valve 904 is opened to drain the test water from the test water tank 200. The third control valve 809 is then opened to supply cleaning water to the cleaning water tank 300 for spray-rinsing the test piece 400. After the spraying is complete, the sixth control valve 906 is opened to drain the water. The fourth control valve 814 is then opened to supply cleaning water to the cleaning water tank 300 for cleaning. After the spraying is complete, the sixth control valve 906 is opened to drain the water.

[0134] Next, the third control valve 809 is opened to supply cleaning water into the test water tank 200 to clean the test water tank 200 . After cleaning, the third control valve 809 is closed.

[0135] Then, the fifth control valve 904 is opened to drain the cleaning water in the test water tank 200, and then the fifth control valve 904 is closed. Then, after cleaning the scrubbing structure 500, the seventh control valve 909 is opened to drain the cleaning water in the rinse water tank 907. The above-mentioned cleaning water supply operations can be performed in any order.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
