[0035] During the implementation of the present invention: the user manually or by other automated devices inserts the sample tube 6 containing the sewage sample into the loading tank, and then starts the first driving member 241, the first driving member 241 rotates forward, at this time the first ratchet does not cooperate with the first pawl, the second ratchet cooperates with the second pawl, the driving gear 242 does not rotate, the bottom sleeve shaft 25 rotates, the top slider 251 drives the bottom slider 26 to move upward, when the bottom slider 26 rises to the highest point of its motion range, the driving gear 242 meshes with the switching gear 212, and then the first driving member 241 reverses, the first ratchet cooperates with the first pawl, the second ratchet does not cooperate with the second pawl, and the driving gear 242 drives the switching gear 212. The gear 212 rotates to rotate one of the sample tubes 6 to one end of the turntable 21 close to the bracket 31, and then the first driving member 241 rotates forward, and the top slider 251 drives the bottom slider 26 to descend. When the bottom slider 26 descends to the lowest point of its motion range, the driving gear 242 meshes with the mixing gear 221 (at this time, the first rack 271 does not mesh with the bottom gear), and then the second driving member is started (when the device is in the initial state, the outer driven block 34 abuts against the rotating seat 312, and the inner driven block 35 abuts against the center sleeve shaft 38). The second driving member rotates forward, and at this time the third ratchet cooperates with the third ratchet, the fourth ratchet does not cooperate with the fourth pawl, the side sleeve shaft 33 rotates, and the center sleeve shaft 38 does not The active block 331 rotates, and moves toward the direction close to the center sleeve shaft 38. During this process, the inner driven block 35 does not move, and it always abuts against the end of the center sleeve shaft 38. The outer driven block 34 moves following the active block 331, so that the lifting plate 311 gradually rises until the lifting connecting rod 341 is in a vertical state, the intermediate gear 314 meshes with the top gear 39, and then the first driving member 241 rotates forward, the top slider 251 continues to descend, the first spring is compressed, and the first rack 271 meshes with the bottom gear, driving the bottom shaft to rotate, so that the rotating seat 312 rotates 180°. At this time, the dropper head 361 is located above the sample tube 6, and its tip is facing upward, and the cross clamp 362 is located at the dropper head 3 61, and then the second driving member rotates forward, the active block 331 drives the outer driven block 34 to continue to move toward the direction close to the center sleeve shaft 38. During this process, the lifting plate 311 moves downward, the dropper head 361 cooperates with the sample tube 6, and then the second driving member reverses. At this time, the third ratchet does not cooperate with the third pawl, and the fourth ratchet cooperates with the fourth pawl. The center sleeve shaft 38 rotates to move the center block 381. Under the meshing action of the second rack 382 and the clamping gear 372, the rotating member 371 rotates until the clamping protrusion cooperates with the cross clamp 362, and the cross clamp 362 clamps the sample tube 6 (at this time, the sample tube 6 is slightly deformed, but its deformation is not enough to cause the sewage to flow out).Then the second driving member rotates forward, the active block 331 drives the outer driven block 34 to move away from the center sleeve shaft 38, the lifting plate 311 gradually rises until the intermediate gear 314 is meshed with the top gear 39, and then the first driving member 241 rotates forward, causing the sliding member 27 to move toward the fixed shaft 211, and the rotating seat 312 reverses 180°. At this time, the dropper head 361 is located above the detection element (the detection element is arranged on the top surface of the conveyor belt 42), and then the second driving member reverses, and the rotating member 371 rotates until the extrusion protrusion cooperates with the cross clamp 362, and the cross clamp 362 squeezes the sample tube 6, and the sewage sample drips onto the detection element, and then the second driving member rotates forward, causing the active block 331 to move away from the center sleeve shaft 38. Movement, at this time, the outer driven block 34 abuts the rotating seat 312 and no longer moves, and the inner driven block 35 follows the active block 331 to move, and under the action of the reciprocating connecting rod 351, it moves toward the water tank 5 to adjust its position. When it is adjusted to the initial state of the device (that is, the active block 331 moves toward the direction close to the center sleeve shaft 38), the above process is repeated, and the sample tube 6 is put back into the bearing groove, and the rotating member 371 is rotated until the clamping protrusion and the extrusion protrusion are not matched with the cross clamp 362, and then the lifting plate 311 rises and the rotating seat 312 rotates 180°. At this time, the active block 331 moves away from the center sleeve shaft 38, and the dropper head 361 moves to below the water outlet end of the water pipe 51, and the water pump is started to rinse the dropper head 361.

[0036] When continuous detection is required, the user can repeat the above steps. During this process, every time the fixed shaft 211 rotates, the side shaft 44 can be driven to rotate, and the matching block 45 performs reciprocating lifting and lowering motion, so that the conveyor belt 42 moves a certain distance, thereby realizing automatic switching of the detection element.

[0037] The present invention provides a sewage detection device, which has the following beneficial effects:

[0038] By setting up a carrying component, several different sewage samples can be continuously tested, which not only ensures good detection efficiency but also reduces the labor intensity of users. Moreover, when the sewage samples are switched, the detection elements can be automatically replaced, further improving the detection efficiency.

[0039] By setting up the detection component, not only can the sewage samples be automatically taken, placed and tested, but the dropper head can also be automatically flushed during the detection interval to avoid erroneous test results due to sewage adhering to its inner wall, thus ensuring good detection accuracy.

[0040] In summary, the beneficial effects of the present invention are: it can continuously and automatically detect a number of different types of sewage samples, and can automatically clean the dropper head during the detection interval, thereby ensuring good detection efficiency and detection accuracy.

[0041] Of course, the present invention may have a variety of embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
