Existing pH measuring devices have the following main drawbacks: pH electrodes are prone to contamination when immersed in water for extended periods, which affects measurement accuracy; and pH electrodes are easily damaged by rapid water flow. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, this utility model provides a pH electrode measuring device with cleaning and protection functions.

The left and right ends of the test pipe have water inlet pipe and water outlet pipe respectively. The outer walls of one end of the water inlet pipe and water outlet pipe are fixedly connected to flange two.

[0013] like Figure 1-3 As shown: A pH electrode measuring device with cleaning and protection function includes a detection pipe 1; bulges 6 are provided on the front and rear side walls of the detection pipe 1; a base plate 7 is fixedly connected to the inner bottom of the detection pipe 1; a cleaning pipe 8 is fixedly connected to the top of the base plate 7; the top end of the cleaning pipe 8 extends through the top outer wall of the detection pipe 1; a one-way valve 9 is installed at the top end of the cleaning pipe 8; an installation pipe 12 is fixedly connected to the top middle of the detection pipe 1; a pH electrode 13 is provided inside the installation pipe 12; the bottom end of the pH electrode 13 extends to the top of the base plate 7; the cleaning pipe 8 is spiral-shaped and extends upward around the pH electrode 13; the pH electrode 13 includes a sensitive bulb 14; the bottom end of the pH electrode 13 has a sensitive bulb 14; a plurality of nozzles 10 are fixedly connected to the bottom of the outer wall of the cleaning pipe 8; a plurality of nozzles 21 are fixedly connected to the side of the outer wall of the cleaning pipe 8 facing the pH electrode 13; the nozzles 10 and nozzles 21 are evenly distributed along the cleaning pipe 8 and around the pH electrode 13.
[0014] Flange 1 is fixedly connected to the outer walls of both the left and right ends of the detection pipe 1. The left and right ends of the detection pipe 1 have an inlet pipe 3 and an outlet pipe 4, respectively. Flange 2 is fixedly connected to the outer walls of one end of the inlet pipe 3 and the outlet pipe 4. The inlet pipe 3 and the outlet pipe 4 are fixedly connected to the left and right ends of the detection pipe 1 through flange 2 and flange 1, respectively. The other end of the inlet pipe 3 and the outlet pipe 4 bends upward and extends to the top of the detection pipe 1.
[0015] The liquid to be tested enters the detection pipe 1 through the water inlet pipe 3. The liquid flows through the cleaning pipe 8. Since the cleaning pipe 8 is spiral, the liquid flows through the gaps between the outer walls of the cleaning pipe 8, which can reduce the liquid flow speed and reduce the impact of the water flow on the pH electrode 13. The sensitive bulb 14 of the pH electrode 13 is immersed in the liquid to detect the pH value in real time.
[0016] When cleaning the pH electrode, stop the liquid entering pipe 1, and inject clean water or cleaning solution into the cleaning pipe 8 using an external high-pressure water pump. The spiral-shaped cleaning pipe 8 directly rinses the surface of the pH electrode 13 through nozzle 11, while nozzle 10 simultaneously rinses the outer wall of the cleaning pipe 8 to remove any adhering substances. After rinsing, the one-way valve 9 prevents backflow of liquid. The function of the one-way valve 9 is to allow water to enter the interior of pipe 1 but prevent water from flowing out of the interior of pipe 1 through the one-way valve 9, ensuring the system's airtightness.
[0017] If the system stops supplying water, the liquid accumulated in the detection pipe 1 can temporarily cover the sensitive bulb 14 because the design of the inlet pipe 3 and outlet pipe 4 is higher than that of the detection pipe 1, thus preventing the pH electrode 13 from failing due to dryness and extending its service life.
[0018] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
