[0003] The high alkalinity pH electrode device mainly consists of an alkali-resistant electrode measuring component, an electrode assembly, and a corrosion-resistant housing. Its working principle is that the alkali-resistant glass electrode measuring component is responsible for sensing the hydrogen ion activity in the solution, the dual reference electrode assembly provides a stable potential reference, and the corrosion-resistant housing protects the internal components from corrosion by high alkaline solutions, thus realizing accurate measurement and long-term stable operation of the electrode in a high alkaline environment.
[0004] Traditional high-alkalinity pH electrode devices have many limitations and inconveniences in use. Their structural design is relatively fixed, the measurement position is difficult to adjust, and multi-angle measurement cannot be achieved by rotating parts. For experimental solutions in different positions in the container, traditional devices cannot accurately measure them and require repeated adjustment of the container or electrode position, which is cumbersome and inefficient. Therefore, a high-alkalinity pH electrode device is proposed to solve the above problems. Utility Model Content

[0032] 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a high alkalinity pH electrode device, comprising an operating table 1, a ball chain 2 fixedly connected to the right end of the operating table 1, a rotating column 3 rotatably connected to the top end of the ball chain 2, allowing the operator to rotate the rotating column 3 to a designated position via multiple angles through the rotatable connection between the ball chain 2 and the rotating column 3; a ball chain 4 fixedly connected to the top end of the rotating column 3, a rotating column 5 rotatably connected to the right end of the ball chain 4, allowing the operator to rotate the rotating column 5 to a designated position via multiple angles through the rotatable connection between the ball chain 4 and the rotating column 5; and a fixed column 6 fixedly connected to the outside of the rotating column 5. 6 provides support for the fixed rod 7. The outside of the rotating column 2 5 is equipped with a cleaning component. The cleaning component can clean the solution impurities on the outside of the measuring rod 12 after the experiment, avoiding direct contact between the operator and the measuring rod 12. The front end of the rotating column 2 5 is equipped with an adjustment component. The adjustment component can adjust the position of the measuring rod 12, so that the operator can measure the acidity and alkalinity at different positions of the solution. The adjustment component includes a support block 13. The support block 13 is fixedly connected to the front end of the rotating column 2 5. The inside of the support block 13 is slidably connected with a sliding rod 14. The position of the limiting clamp 15 can be adjusted by the sliding rod 14, so that the operator can adjust the position of the measuring rod 12.
[0034] A limiting clamp 15 is fixedly connected to the end of the sliding rod 14 away from the support block 13. The limiting clamp 15 provides clamping force for the measuring rod 12, fixing its position. A nut 16 is threaded onto the outside of the sliding rod 14. Through the threaded connection between the nut 16 and the sliding rod 14, the operator can adjust the position of the limiting clamp 15. The measuring rod 12 is located inside the support block 13 and can measure the acidity or alkalinity of the solution. A groove is opened on the outside of the ball chain 4, which can fix the rotating column 5 on the finger. The fixed rod 7 has a groove inside, which restricts the movement direction and position of the sliding column 8. The outside of the nut 16 contacts the outside of the support block 13. Through the contact between the nut 16 and the support block 13, the position of the sliding rod 14 is fixed in the designated position inside the support block 13. The limiting clamp 15 is arc-shaped. Through the arc design, it can clamp measuring rods 12 of different thicknesses. The outside of the limiting clamp 15 is set inside the support block 13. The ball chain 2 has a groove on its outside.
[0035] Reference Figure 1 , Figure 4 and Figure 5The cleaning assembly includes a fixed rod 7, which is externally fixedly connected to the end of the fixed column 6 away from the rotating column 5. The fixed column 6 provides support for the fixed rod 7. A sliding column 8 is slidably connected inside the fixed rod 7. A follower rod 9 is fixedly connected to the bottom end of the sliding column 8. The movement of the sliding column 8 drives the follower rod 9 to move. A connecting column 10 is fixedly connected to the bottom end of the follower rod 9. The movement of the follower rod 9 drives the connecting column 10 to move. A cleaning brush 11 is fixedly connected to the end of the connecting column 10 away from the follower rod 9. The movement of the connecting column 10 drives the cleaning brush 11 to reciprocate scraping motion. The cleaning brush 11 is internally slidably connected to the outside of the measuring rod 12. Through the sliding connection, the cleaning brush 11 cleans the outside of the measuring rod 12, achieving a cleaning effect. The inside of the limiting clamp 15 is in contact with the outside of the support block 13. The rear end of the fixed rod 7 is provided with a semi-circular groove. Through the design of the semi-circular groove, when cleaning is not required, the sliding column 8 can be slid into the semi-circular groove to prevent it from wobbling left and right. The outside of the sliding column 8 slides inside the semi-circular groove.
[0036] Working principle: When the operator uses the pH electrode device in the laboratory, rotate rotating column 3 to the designated position, then rotate rotating column 5 to the designated position of the external groove of ball chain 4, unfold the support block 13, slide the measuring rod 12 into the support block 13, and rotate the nut 16 to fix the position of the measuring rod 12 with the limiting clamp 15. At this time, the operator can rotate rotating column 3 and rotating column 5 to different positions at multiple angles to achieve the measurement effect of experimental solutions at different positions. At the same time, the operator can rotate the nut 16 in the opposite direction to remove the fixing of the limiting clamp 15 to the measuring rod 12, so that the measuring rod 12 can measure the acidity and alkalinity of the solution at different heights.
[0037] When the operator needs to clean the measuring rod 12, pushing or pulling the sliding column 8 causes the follower rod 9 to drive the cleaning brush 11 to repeatedly scrape the outside of the measuring rod 12, thus cleaning the outside of the measuring rod 12 and avoiding direct contact between the operator and the measuring rod 12, thereby improving safety.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
