The electric push rod 2 is installed on the top of the rear end of the base 1, and the detection rod 3 is installed at the bottom of the electric push rod 2. A cleaning mechanism for cleaning the detection rod 3 is provided at the rear end of the base 1. A reagent adding cylinder 4 is welded at the middle top of the base 1, and a servo motor 6 is installed at the rear end of the base 1. The screw rod 7 is rotatably connected in the base 1. The screw rod 7 is a bidirectional threaded screw rod, and the rear end is welded to the output shaft of the servo motor 6. The fixed rack 8 is welded on the base 1, and the sliding seat 10 is slidably connected in the base 1 and is slidably connected with the screw rod 7. After the servo motor 6 is turned on, when the sliding seat 10 moves to the end of the screw rod 7, the servo motor 6 continues to drive the screw rod 7 to rotate, and the sliding seat 10 can move in the opposite direction. The placement cylinder 5 is rotatably connected to the top of the sliding seat 10, and a gear ring 9 is welded at the bottom of the placement cylinder 5, and the gear ring 9 is meshed with the fixed rack 8.
[0025] like Figure 5-Figure 7As shown, the cleaning mechanism includes a stepper motor 11, a fixed seat 12, a column gear 13, a rotating cylinder 14, a cleaning block 15 and a spring Ⅰ 16. The stepper motor 11 is installed at the rear end of the base 1, and a driving gear is connected to the top of the stepper motor 11. The fixed seat 12 is welded to the front side of the rear end of the base 1. The rotating cylinder 14 is rotatably connected to the fixed seat 12. The column gear 13 is welded to the bottom of the rotating cylinder 14 and meshes with the driving gear connected to the output shaft of the stepper motor 11. Four grooves are opened on the inner bottom plate of the rotating cylinder 14. The lower ends of the four cleaning blocks 15 are slidably connected. It is connected to the groove corresponding to the rotating cylinder 14, and a round rod is welded in the groove. The cleaning block 15 is slidably connected to the round rod. A spring Ⅰ16 is sleeved on the round rod. One end of the spring Ⅰ16 is welded to the bottom of the cleaning block 15, and the other end is welded to the inner wall of the groove. A large square groove is opened on the top of the rotating cylinder 14. The top of the cleaning block 15 is slidably connected to the side of the square groove. When the top of the cleaning block 15 contacts with a right angle, it moves away from the center, and when it contacts with the right angle side, it moves closer to the center, thereby realizing reciprocating movement. A water-absorbing long-haired brush is provided at the inner end of the cleaning block 15.
[0026] The staff puts the water to be tested into the test tube, places the test tube in the placement tube 5, then turns on the servo motor 6, drives the sliding seat 10 to move through the screw rod 7, and at the same time the gear ring 9 and the fixed rack 8 are engaged to drive the placement tube 5 to rotate, and the liquid in the test tube is shaken evenly. When it reaches the bottom of the reagent adding tube 4, the servo motor 6 is turned off, and the reagent is added to the test tube. Then the servo motor 6 is turned on and continues to move backward. At the same time, the rotating placement tube 5 can fully mix the water and the reagent to ensure that the solution is uniform. When the placement tube 5 moves to the rear end, the servo motor 6 is turned off, the electric push rod 2 is turned on, and the detection rod 3 is inserted into the test tube and rises. To conduct water quality testing, the electric push rod 2 is closed after the detection rod 3 is reset, and then the test result is output, the servo motor 6 is turned on, and the bidirectional threaded screw moves the placement tube 5 forward. The staff replaces the test tube and tests the next portion of water. When the electric push rod 2 is turned on, the stepper motor 11 is also turned on at the same time, and the rotating tube 14 is driven to rotate through the column gear 13, so that the top of the cleaning block 15 is squeezed by the rotating tube 14, and through the spring Ⅰ16, it reciprocates in the rotating tube 14, so that the surface of the detection rod 3 is cleaned and dried to ensure the accuracy of each test. When the electric push rod 2 is closed, the stepper motor 11 is also turned off at the same time.

[0028] like Fig. 9As shown, a liquid guiding hopper 20 is also included, and the liquid guiding hopper 20 is welded to the bottom end of the reagent adding cylinder 4.
[0029] like Figure 4 As shown, a heating pad 21 is also included, and the heating pad 21 is welded on the top of the sliding seat 10.
[0030] like Figure 8 As shown, a roller 22 is also included, and the roller 22 is rotatably connected to the inner side of the clamping plate 17.
[0031] When placing the test tube into the placement tube 5, the test tube enters through the clamp 17, and the clamp 17 is pushed to both sides to stretch the spring II 19. The roller 22 can make the process of placing the test tube smoother, and there is a rubber sleeve in the middle of the roller 22 to make the test tube more stable, so that the test tube will not slide when the placement tube 5 is rotated. Special liquids decide whether to turn on the heating pad 21 according to the detection requirements. The liquid guide bucket 20 can make the reagent completely enter the test tube without spilling outside. After the test is completed, the test tube is taken out and the spring II 19 rebounds.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
