[0033] In this embodiment, the driving device 7 includes a driving screw 701 and a driving motor 702 .

[0034] A first delivery tube 902 and a second delivery tube 904 are respectively arranged on the outside of the pH detection electrode rod 3, and the first delivery tube 902 and the second delivery tube 904 are arranged as a group, which are used to achieve the cleaning effect of the pH detection electrode rod 3. When cleaning the pH detection electrode rod 3, the first delivery tube 902 and the infusion pump 906 are started, and the cleaning liquid and clean water are transported through the connecting tube 901. The connecting tube 901 is inserted into the direct tube 801. The other end of the connecting tube 901 is provided with a hose, which is arranged on the inner side of the protective tube shell 4 and is externally connected to the cleaning liquid storage device and the clean water storage device. The storage device, and the cleaning pump 905 and the infusion pump 906 will not be started at the same time. When cleaning, the infusion pump 906 is started first to deliver the cleaning liquid. While the pH detection electrode rod 3 is retracted into the protective shell 201, the cleaning liquid cleans the pH detection electrode rod 3. After the cleaning liquid cleans the pH detection electrode rod 3, the pH detection electrode rod 3 is extended from the inside of the protective shell 201, and the cleaning pump 905 is started. The cleaning pump 905 draws clean water and cleans the pH detection electrode rod 3 through the cleaning mechanism 5. After air drying, the pH detection electrode rod 3 can continue to be used for pH detection.

[0035] The working principle of the present invention is as follows: when detecting the pH value of the liquid, the pH detection electrode rod 3 will come out from the inside of the protective shell 201. When the pH detection electrode rod 3 needs to be cleaned, the drive motor 702 is started, and the drive motor 702 drives the drive screw 701 to rotate. The rotation of the drive screw 701 will cause the lifting carrier 607 in the lifting mechanism 6 to rise. At the same time, the lifting carrier 607 will drive the double-hole fixing plate 609 to rise, thereby driving the two pH detection electrode rods 3 to enter the protective shell 201, which can not only store them, but also drive the cleaning mechanism 5 to clean the pH detection electrode rods 3.

[0036] When the pH detection electrode rod 3 is lifted, the spring wire is compressed, and when the pH detection electrode rod 3 is lowered, the spring wire is released, so that the spring wire can be extended or shortened to adapt to the height change of the pH detection electrode rod 3.

[0037] When the lifting carrier 607 is raised, the fixed block 605 will be raised, thereby driving the annular fixed rail 604 and the lifting gear ring 602 to rise. Due to the setting of the rotation groove 603 and the spiral guide rail 606, when the lifting gear ring 602 is raised, it will rotate at the same time. The rotation of the lifting gear ring 602 will drive the power gear 601 to rotate, and the rotation of the power gear 601 will drive the conduction long rod 504 to rotate, thereby providing power for the cleaning mechanism 5 through the conduction long rod 504.

[0038] When the conductive rod 504 rotates, the conductive rod 504 will drive the driving gear 501 to rotate together, and the rotation of the driving gear 501 will drive the linkage gear ring 5011 to rotate. The rotation of the linkage gear ring 5011 will also drive the two cleaning gear rings 502 to rotate. The rotation of the cleaning gear ring 502 will drive the cleaning round brush 503 to rotate. The cleaning round brush 503 cleans the residual liquid on the outside of the pH detection electrode rod 3, thereby achieving a quick cleaning effect, and does not require disassembly and installation, thereby improving the cleaning efficiency and further improving the detection efficiency of sewage. The top of the water-passing cover plate 507 is provided with a plurality of small holes for the passage of cleaning liquid and clean water. The cleaning liquid and clean water will fall on the cleaning round brush 503, and will be used when cleaning the pH detection electrode rod 3.

[0039] A first delivery tube 902 and a second delivery tube 904 are provided above a cleaning round brush 503. When cleaning the pH detection electrode rod 3, the first delivery tube 902 and the infusion pump 906 are started, and the cleaning liquid and clean water are delivered through the connecting tube 901. The connecting tube 901 is inserted into the direct tube 801. A hose is provided at the other end of the connecting tube 901. The hose is provided on the inner side of the protective tube shell 4 and is externally connected to the cleaning liquid tank and the water tank. The cleaning pump 905 and the infusion pump 906 are not started at the same time. When cleaning, the infusion pump 906 is first started to deliver the cleaning liquid. While the pH detection electrode rod 3 is retracted into the protective shell 201, the cleaning liquid cleans the pH detection electrode rod 3. After the cleaning liquid cleans the pH detection electrode rod 3, the pH detection electrode rod 3 extends from the inside of the protective shell 201, and the cleaning pump 905 is started. The cleaning pump 905 draws clean water, and the pH detection electrode rod 3 is cleaned through the cleaning mechanism 5. After air drying, the pH detection electrode rod 3 can continue to be used for pH detection.

[0040] In addition, the protective component 2 is configured to be detachable for easy maintenance of its interior. The configuration of the bottom connecting ring 203 can make the linkage gear ring 5011 more stable during rotation. The vertical guide rail 205 is used to stabilize the lifting mechanism 6 and the spring wire will shrink or lengthen as the pH detection electrode rod 3 rises and falls.
