DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In this embodiment, an automatic measurement device for the concentration of chemical solution includes a mounting plate 1. The mounting plate 1 can be used to conveniently and quickly install the whole. A tube body 2 is fixed inside the mounting plate 1. The tube body 2 is used to protect the detection device 13. A prism 3 is fixed to the inner top wall of the tube body 2. A cover plate 4 is fixed to the right side of the tube body 2. A driving assembly is arranged on the left side of the mounting plate 1. The driving assembly includes a driving motor 5 fixed to the mounting plate 1. The driving motor 5 is used to drive the pushing assembly 8 to rotate. A driving gear 6 is fixed to the outer surface of the output shaft of the driving motor 5. A driven gear 7 is meshed with the bottom of the driving gear 6. The driving gear 6 and the driven gear 7 are both used for transmission.

[0021] In addition, the axis of the driven gear 7 is fixed to the rotating rod 801, and the internal rotation of the mounting plate 1 is connected to a pushing assembly 8 fixed to the driving assembly. The driving assembly is used to drive the pushing assembly 8 to rotate. A cleaning assembly is fixed to the right side of the pushing assembly 8. The pushing assembly 8 is used to push the cleaning assembly to move. The cleaning assembly includes a connecting block 9 fixed to the rotating block 806. Two connecting rods 10 are fixed on the upper and lower sides of the connecting block 9. A support spring 11 is fixed on the side of the connecting rod 10 away from the connecting block 9. The support spring 11 can effectively support the cleaning brush 12, so that the cleaning brush 12 can be in closer contact with the prism 3, thereby making the cleaning more efficient. A cleaning brush 12 is fixed on the side of the support spring 11 away from the connecting rod 10. The cleaning assembly is used to clean the prism 3, and a detection device 13 is fixed inside the tube body 2.

[0022] In general, the support spring 11 can support the cleaning brush 12, so that the cleaning brush 12 can contact the prism 3 with greater force, thereby making the cleaning more complete.

[0023] See also Figure 3 In order to make the measurement more accurate, the pushing assembly 8 in this embodiment includes a rotating rod 801 rotatably connected to the mounting plate 1, the internal thread of the rotating rod 801 is connected to the moving rod 802, the outer surface of the moving rod 802 is fixed with a threaded bar, and a threaded hole compatible with the threaded bar is opened on the right side of the rotating rod 801. When the rotating rod 801 rotates, the moving rod 802, which cannot rotate, will move due to the extrusion of the thread. A telescopic rod 803 fixed to the moving rod 802 is fixed on the right side of the mounting plate 1, and the telescopic rod 803 is provided to limit the rotation of the moving rod 802.

[0024] The cam 804 is connected to the rear of the lever 802 and the lever 806 is connected to the rear of the lever 802 so that the lever 802 can be rotated.

[0025] In general, by rotating the rotating rod 801, the moving rod 802 can push the cleaning component to move, and the rotation of the rotating rod 801 will cause the connecting block 804 and the connecting rod 805 to drive the cleaning component to rotate, making the cleaning more efficient and effectively improving the overall practicality.

[0026] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0027] The working principle of the above embodiment is:

[0028] When the prism 3 needs to be cleaned, the driving motor 5 is started, and the rotating rod 801 is rotated under the transmission of the driving gear 6 and the driven gear 7, while the moving rod 802 is restricted in rotation by the telescopic rod 803, so that the moving rod 802 moves due to the extrusion of the thread, thereby moving the cleaning component. When the rotating rod 801 rotates, the rotating block 806 is rotated together under the transmission of the connecting block 804 and the connecting rod 805, so that the cleaning component rotates while moving, effectively improving the cleaning effect. After the cleaning is completed, the driving motor 5 can be reversed to move the cleaning component back. The overall structure is simple, and the measurement result is more accurate, which makes the overall structure more practical.
