[0026] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a vanadium electrolyte concentration detection device, including a titrator 1 for accurately measuring the concentration of vanadium electrolyte. A display screen 2 is installed on one side of the titrator 1 for setting various parameters in the detection. A placement groove 3 is opened on the upper surface of the titrator 1 for placing the titrant required for the detection. A stirring table 4 is installed on the side of the titrator 1 away from the placement groove 3, and the solution is uniformly mixed by magnetic stirring. A positioning groove 5 is opened on the upper surface of the stirring table 4 for placing the vanadium electrolyte.

[0028] refer to Figures 1-3A support column 6 is installed on the side of the titrator 1 near the stirring table 4. The support column 6 has a hollow structure, and a groove is opened on the outer wall of the side of the support column 6 near the stirring table 4. A support rod 11 is installed in the groove. The outer end of the support rod 11 has a hollow frame structure. A lead screw 12 is rotatably connected to the inner wall of one side of the hollow frame of the support rod 11. The lead screw 12 has a structure with opposite threads at both ends. The other end of the lead screw 12 passes through the inner wall of the other side of the hollow frame of the support rod 11, and a knob 13 is fixedly connected to this end. Turning the knob 13 can perform titration. As the lead screw 12 rotates, a positioning rod 14 is fixedly connected to one side of the lead screw 12. Two opposing clamping plates 15 are movably connected to the body of the positioning rod 14. The lead screw 12 passes through the clamping plates 15 and is movably connected to the clamping plates 15 by threads. A burette 16 is arranged between the two clamping plates 15. There is a large space between the lead screw 12 and the positioning rod 14, which is sufficient for the burette 16 to be inserted. After the lead screw 12 rotates, the two clamping plates 15 will move in opposite directions, thereby adjusting the distance between the two clamping plates 15.

[0029] refer to Figures 4-5 The inner wall of the support column 6 is provided with symmetrical connecting grooves 61. A toothed column 7 is slidably connected inside the connecting groove 61. The toothed column 7 is a square column structure with several toothed grooves evenly opened on one side. A motor 8 is installed on the side of the toothed column 7 with toothed grooves. The motor 8 is connected to the display screen 2 for signal control.

[0030] refer to Figure 6 The end of the support rod 11 is fixedly connected to the toothed column 7 on the side opposite to the tooth groove. The motor 8 is fixedly connected to the inner wall of the support column 6. A rotating rod 9 is fixedly connected to the output end of the motor 8. The other end of the rotating rod 9 is rotatably connected to the inner wall of the support column 6. A gear 10 is fixedly connected to the rod body of the rotating rod 9. (Reference) Figure 7 The gear 10 meshes with the tooth groove on the gear column 7; after the motor 8 runs, the rotating rod 9 drives the gear 10 to rotate, and the gear column 7 meshes with the gear 10 to drive the gear column 7 to move up and down in the connecting groove 61, thereby enabling the support rod 11 to drive the burette 16 to move up and down.

[0031] In this embodiment, a burette 16 with a suitable capacity is selected according to the requirements of the test. The titration cup containing the vanadium electrolyte sample is placed in the positioning groove 5. The titrant required for the test is placed in the placement groove 3 and connected to the selected burette 16 through a tube. The burette 16 is inserted into the hollow part of the support rod 11. The distance between the clamping plates 15 is adjusted by rotating the knob 13 until the clamping plates 15 fix the burette 16.

[0032] The height of the burette 16 is adjusted by rotating the drive motor 8, so that the height of the burette 16 can be controlled according to the amount of sample liquid, preventing the burette 16 from being too high and causing the titrant to drip rapidly into the test solution and splashing the solution, thus greatly improving the safety of the test.

[0033] After setting the parameters of the detection process via display screen 2, the detection begins. While the titrant is added to the sample, the stirring table 4 performs magnetic stirring. That is, a small magnetic ball placed at the bottom of the titration cup is driven to rotate by a rotating magnetic field set inside the titrator 1, thereby achieving effective stirring of the solution. The titrator 1 then detects the concentration of the vanadium electrolyte.
