[0002] In environmental protection work, environmental protection departments often need to add reagents to collected sewage samples for testing in order to develop corresponding treatment plans. This requires the use of titration equipment to control the titration amount of the titrant. The commonly used titration equipment is the burette.

[0003] Existing titration devices are equipped with multiple burettes for easy switching between different reagents. However, when switching between different burettes, the operator needs to observe whether the burette is directly above the test cup, resulting in low switching efficiency. After the reagent is dispensed, manual stirring is often required to accelerate mixing. After multiple experiments, the operator's arms are prone to fatigue, which can reduce work efficiency. Utility Model Content

[0013] According to the titration device for water resource environment testing, both the pressure plate and the rubber pad have arc-shaped cross-sections.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. By rotating the third fixing bolt, the fixing of the telescopic rod can be easily released. By rotating the telescopic rod, the motor and the stirring plate can be positioned above the test bottle. The limiting hole allows for easy adjustment of the telescopic rod's rotation.

The motor 15 drives the rotating disk 18 and the stirring rod 17 to stir.

[0028] A positioning hole 22 is opened on the upper surface of the base 1, and a laser lamp 7 is fixedly connected to the lower surface of the four support rods 3. The laser beam emitted by the laser lamp 7 is placed inside the positioning hole 22, thereby assisting the staff in switching reagents.

[0029] A placement groove 19 is formed on the upper surface of the base 1. A suction cup 20 is fixedly connected to the bottom surface of the placement groove 19. A test bottle 8 is placed inside the placement groove 19. The upper surface of the suction cup 20 is adsorbed to the lower surface of the test bottle 8. The test bottle 8 is placed inside the placement groove 19 and adsorbed by the suction cup 20.

[0030] The center of the placement groove 19 is on the same horizontal line as the positioning hole 22, so that when the laser beam 7 is inside the positioning hole 22, the burette can be positioned directly above the test bottle 8.

[0031] Mounting holes are provided at all four corners of the upper surface of base 1. The mounting holes are through-holes, and workers can use screws to reinforce it.

A second fixing bolt 5 is threadedly connected to the side of the rotating cylinder 14. One end of the second fixing bolt 5 is in contact with the side of the rotating main rod 6. One end of the support rod 3 is fixedly connected to the side of the rotating cylinder 14. The rotating cylinder 14 drives the support rod 3 to rotate, and the rotating cylinder 14 is fixed by the second fixing bolt 5.

[0033] The end of the support rod 3 away from the rotating cylinder 14 is fixedly connected to the clamping cylinder 4. The clamping cylinder 4 is fitted with a pressure plate 10. The side of the pressure plate 10 is fixedly connected to a rubber pad 12. The clamping cylinder 4 is threadedly connected to a first fixing bolt 2.

[0035] Both the pressure plate 10 and the rubber pad 12 have arc-shaped cross sections, which match the clamping cylinder 4.

[0036] Working principle: In use, the operator first places the test bottle 8 inside the placement slot 19, and uses the suction cup 20 to adhere to the bottom of the test bottle 8. Then, the burette is placed inside the clamping cylinder 4. Then, the first fixing bolt 2 is rotated to drive the pressure plate 10 and the rubber pad 12 to fix the burette. When it is necessary to switch different reagents, the second fixing bolt 5 is first released from the limit of the rotating cylinder 14. Then, the support rod 3 is rotated to make the corresponding reagent above the test bottle 8. The laser emitted by the laser lamp 7 is inside the positioning hole 22, which helps the operator switch different reagents and improves the efficiency of the operator. After the reagent is added, the third fixing bolt 11 is first released from the limit of the telescopic rod 21. Then, the telescopic rod 21 is rotated 180 degrees to make the stirring rod 17 above the test bottle 8. Then, the height of the stirring rod 17 is adjusted using the limiting hole 9 on the telescopic rod 21 so that the stirring rod 17 is inside the test bottle 8. Then, the motor 15 is started to drive the stirring rod 17 to stir the reagent.
