[0024] The following is in conjunction with the appendix Figures 1-7 Further description of this utility model: An adjustable double-beam ultraviolet-visible spectrophotometer includes a detection chamber 1, a display screen 2 on the detection chamber 1, a detection slot 3 inside the detection chamber 1, a light shield 11 rotatably mounted on the top of the detection slot 3, a handle 12 fixedly mounted on the light shield 11, and ultraviolet emitters 4 and ultraviolet receivers 5 respectively arranged on the inner walls of both sides of the detection slot 3. The ultraviolet emitters 4 and ultraviolet receivers 5 are electrically connected to the display screen 2, which facilitates the reading of values ​​by the staff.

[0025] A detection support plate 6 is slidably installed at the bottom of the detection groove 3 along the length of the detection groove 3. A drive component 7 for moving the detection support plate 6 is provided inside the detection groove 3. Cuvettes 8 are distributed on the detection support plate 6. Support seats 9 for supporting cuvettes 8 of different sizes are provided at equal intervals on the detection support plate 6. Clamping components 10 are provided at equal intervals inside the detection support plate 6. The clamping components 10 include clamping plates 1001, which are used to clamp the cuvettes 8.

[0026] like Figure 4 and Figure 5As shown, the drive assembly 7 includes a drive motor 701, which is embedded in the inner wall of one end of the detection tank 3. A control panel 13 is fixedly installed on the outer wall of one side of the detection chamber 1. The control panel 13 is electrically connected to the drive motor 701. A drive screw 702 is fixedly installed at the output end of the drive motor 701. The detection support plate 6 has a screw hole 703 and a guide hole 704 respectively. The drive screw 702 passes through the screw hole 703 and rotates and meshes with the screw hole 703. One end of the drive screw 702 is rotatably installed on the inner wall of one end of the detection tank 3. A guide rod 705 is inserted into the guide hole 704. The two ends of the guide rod 705 are fixedly connected to the inner wall of the detection tank 3, so that when adjusting the detection of solutions in different cuvettes 8, the control panel 13 controls the rotation of the drive motor 701, and the drive motor 701 controls the rotation of the drive screw 702. The device moves under the control of the control panel 13, allowing the drive screw 702 to move the cuvette 8 on the detection support plate 6 to one side of the ultraviolet emitter 4. This enables the detection of the solution in the cuvette 8. After the solution in one cuvette 8 has been detected, the drive motor 701 is rotated via the control panel 13 to move the next cuvette 8 to one side of the ultraviolet emitter 4, facilitating the detection of solutions in multiple cuvettes 8. Compared with traditional equipment, this device eliminates the need for manual adjustment of the detection support plate 6. Manual adjustment is prone to uneven pulling force, causing significant shaking or even spillage of the solution in the cuvette 8. The drive screw 702 ensures stable movement of the detection support plate 6, greatly improving stability during movement. Furthermore, the drive screw 702 is a high-precision ball screw, further enhancing the reliability of the device.

[0027] like Figure 6 and Figure 7As shown, the support base 9 is located on both sides of the bottom of the cuvette 8. A motor switch 14 is provided on the surface of one side of the support base 9. The upper surface of the detection support plate 6 is provided with equally spaced sliding grooves. The clamping plate 1001 is symmetrically slidably engaged in the sliding groove. A pressure sensor 15 is fixedly installed on the clamping plate 1001. The clamping assembly 10 includes a clamping motor 1002 and a clamping screw 1003. The clamping motor 1002 is fixedly installed on one side of the detection support plate 6. The clamping screw 1003 is rotatably installed in the sliding groove. The output end of the clamping motor 1002 is fixedly connected to the clamping screw 1003. The lower end of the clamping plate 1001 is sleeved on the clamping screw 1003. The clamping motor 1002 and the motor switch 14 are electrically connected to each other to facilitate the operator to place the cuvette. When cuvette 8 is placed on support 9, the stepped shape of support 9 allows it to accommodate cuvettes 8 of different sizes. When cuvette 8 is placed on support 9, motor switch 14 is activated. At this time, clamping plates 1001, which were originally located at both ends of the sliding groove, can clamp screw 1003 and move clamping plates 1001 under the activation of clamping motor 1002, thereby clamping cuvette 8. When clamping plate 1001 contacts cuvette 8, if the clamping force of clamping plate 1001 on cuvette 8 exceeds the specified value of pressure sensor 15, the electrical connection between pressure sensor 15 and control panel 13 will allow control panel 13 to shut off clamping motor 1002, thereby ensuring stable clamping of cuvette 8. This method is highly practical.
