[0021] Please refer to Figures 1 - 5 , a device for determining sulfide in water quality according to the present utility model, comprising: a protective cover 1, a fixed seat 2 is fixedly connected to the outer wall of one side of the top end of the protective cover 1, a fixed rod 3 is fixedly connected to the upper end of the fixed seat 2, a cross bar 4 is fixedly connected to one side of the top end of the fixed rod 3, a limiting block 5 is fixedly connected to one side of the lower part of the middle of the cross bar 4, a sliding rod 6 is fixedly connected to one side of the bottom end of the limiting block 5, a screw rod 7 is fixedly connected to one side of the bottom end of the sliding rod 6, a movable sleeve 8 is slidably sleeved on the outer wall of the sliding rod 6, a rotating ring 9 is screwed to the screw rod 7, a reaction tank 10 is arranged on one side of the lower end of the protective cover 1, stirring blades 11 are fixedly arranged on the outer wall of the rotating ring 9, a rotating opening 12 is formed in the middle of the rotating ring 9, a movable ring 13 is sleeved on the outer wall of the screw rod 7 near the lower end of the rotating ring 9, and a spring 14 is sleeved on the outer wall of the screw rod 7 near the lower end of the movable ring 13.

[0022] As Figure 2 and Figure 3 shown, an upper bearing 15 is arranged at one end of the movable sleeve 8 close to the rotating ring 9. By cooperating the movable sleeve 8 with the upper bearing 15, it is convenient to push the rotating ring 9 downward to rotate spirally along the screw rod 7. A lower bearing 16 is arranged on one side of the movable ring 13 close to the rotating ring 9. By cooperating the movable ring 13 with the lower bearing 16 and the spring 14, it is convenient to push the rotating ring 9 upward to make a spiral movement along the screw rod 7. The numbers of the fixed rod 3 and the stirring blades 11 are both set to two. The outer diameter of the sliding rod 6 is the same as the inner diameter of the movable sleeve 8. The sliding rod 6 is convenient for guiding the movable sleeve 8. The limiting block 5 is cylindrical. The upper end of the movable sleeve 8 can be limited by the limiting block 5. The movable sleeve 8 fits and slidably penetrates the inner wall of the protective cover 1 and extends into the reaction tank 10. The screw rod 7 is located inside the reaction tank 10. The inside of the rotating opening 12 is in the shape of an opposing arc, so as to facilitate the rotation of the rotating ring 9 on the screw rod 7. The rotating opening 12 is threadedly connected to the screw rod 7.

[0023] Among them, one side of the lower end of the upper bearing 15 contacts the swivel ring 9, and one side of the upper end of the lower bearing 16 contacts the swivel ring 9. The swivel ring 9 can be rotated conveniently through the upper bearing 15 and the lower bearing 16. One side of the upper end of the spring 14 is fixedly connected to the movable ring 13. The swivel ring 9 can move spirally downward and then spirally upward through the spring 14. A limit disc 17 is fixedly arranged on one side of the bottom end of the screw rod 7, so as to limit the lower end of the spring 14. The movable sleeve 8 extends to the outer wall of one side of the upper end of the protective cover 1 and is fixedly connected to a pressing rod 18. The number of the pressing rods 18 is two. By pressing the pressing rod 18 finally, the swivel ring 9 can be made to drive the stirring blade 11 to rotate.

[0024] Specifically, when the present utility model is used, the pressing rod 18 can be manually pressed downward, so that the pressing rod 18 drives the movable sleeve 8 to move downward along the sliding rod 6. Then, the movable sleeve 8 drives the upper bearing 15 to move. The swivel ring 9 is pushed by contacting the upper bearing 15, so that the swivel ring 9 spirally moves downward along the screw rod 7 through the rotation port 12. Thus, the stirring blade 11 is driven to rotate through the rotation port 12 to stir the liquid in the reaction tank 10. And when the downward pressing of the pressing rod 18 stops, the movable ring 13 is pushed upward under the elastic force of the spring 14. The lower bearing 16 is driven to move upward by the movable ring 13, so that the lower bearing 16 pushes the swivel ring 9 upward. Therefore, the swivel ring 9 can be made to rotate spirally upward along the screw rod 7. (The process of determining water quality sulfide is recorded in Chinese Patent No. CN214427422U, so it will not be elaborated here).
