[0029] As shown in Figure 8 The gear one 511, the gear two 512 and the gear three 514 are provided with multiple groups. When working, the corresponding gear one 511 and other components drive the corresponding stirring plate 522 to rotate.

[0030] As shown in Figures 1-9 The application provides a water pollution rapid detection reagent feeding method, which comprises the following steps: S1, first, the reagent is placed into the bin 34, then the turbine 23 is driven to rotate, the connecting arm 231 pushes the push plate 323, the sliding block 32 drives the feeding cup 321 to move to the inlet pipe 11, the cover plate 322 is separated from the closing plate 33 during the movement, so that the feeding cup 321 is opened, the reagent enters the inlet pipe 11 and then enters the detection tank 1; S2, at the same time, the driving gear 221 drives the spline gear 253 to rotate, thereby driving the driven column 25 and the connecting column 29 to rotate, and further driving the stirring mechanism 5 below to rotate, so that the reagent is stirred during the feeding process to make the reagent and the sewage mix; S3, in the process of stirring, by driving gear 221 driven gear 24 rotation, in the meshing state with the meshing piece 26, drive connecting column 29 and driven column 25 up and down, so as to fully stir the waste water in the detection tank 1; In operation, first, the reagent is placed in the hopper 34, then drive turbine 23 rotation, using the connecting arm 231 push plate 323, make the sliding block 32 drive the delivery cup 321 to move to the inlet pipe 11, when moving, cover plate 322 and the closure plate 33 lose abutment, so as to open the delivery cup 321, make reagent into the inlet pipe 11, then into the detection tank 1, at the same time, using the driving gear 221 drive bevel gear 253 rotation, thus drive driven column 25 and connecting column 29 rotation, in turn drive the lower stirring mechanism 5 rotation, in the process of reagent delivery, stirring, make reagent and sewage fusion, in the process of stirring, by driving gear 221 driven gear 24 rotation, in the meshing state with the meshing piece 26, drive connecting column 29 and driven column 25 up and down, so as to fully stir the waste water in the detection tank 1.

[0031] The working principle of the present application is as follows: first, connect the hopper 34 with the feeding pipe 35, then put the required reagent into the hopper 34, after the reagent reaches the hopper 34, part of the reagent will enter the feeding cup 321 through the feeding pipe 35 and wait for feeding, then pour the contaminated water from the feeding pipe 11 into the detection tank 1, and then start the driving mechanism 2 to drive the stirring mechanism 5 to rotate, when the driving mechanism 2 is working, it will push the push plate 323 on the sliding block 32 to move, when pushing the push plate 323, it will drive the sliding block 32 to move in the sliding groove 311, when the sliding block 32 moves, it will drive the lower feeding cup 321 away from the closing plate 33, because the cover plate 322 is arranged at the bottom of the feeding cup 321, when the feeding cup 321 is above the closing plate 33, the cover plate 322 will be closed due to the abutment of the closing plate 33, then when the push plate 323 pushes the sliding block 32 to move, the feeding cup 321 will gradually move away from the closing plate 33, so that the cover plate 322 is gradually opened, when the cover plate 322 at the bottom of the feeding cup 321 completely loses abutment with the closing plate 33, the cover plate 322 will be completely opened due to gravity, at the same time, the feeding cup 321 is moved to the upper side of the feeding pipe 11, when the cover plate 322 is opened, the reagent in the feeding cup 321 will fall into the feeding pipe 11, and then reach the detection tank 1 through the feeding pipe 11, at the same time, the driving mechanism 2 drives the stirring mechanism 5 to work, with the reagent entering, the reagent and the contaminated water can be quickly and fully mixed, after the feeding is completed, the push plate 323 loses the pushing, and then is pulled back by the extension spring 324, when pulled back, the cover plate 322 contacts with the closing plate 33, and the two abut again during the back movement, so that the cover plate 322 re-closes the feeding cup 321, in the normal closed state, the feeding cup 321 is directly below the feeding pipe 35, when the feeding cup 321 needs to be fed, the feeding cup 321 moves away from the feeding pipe 35, at this time, the push plate 323 behind can close the feeding pipe 35 to prevent the reagent in the feeding pipe 35 from falling out, when back moving, the feeding cup 321 reaches below the feeding pipe 35 again, and the reagent is fed into the feeding cup 321 through the feeding pipe 35, waiting for the next feeding, through the setting of the feeding part 3, the push plate 323 can be moved when the driving mechanism 2 drives the stirring mechanism 5 to work, so that the feeding cup 321 below the sliding block 32 moves away from the closing plate 33, thereby feeding the reagent in the feeding cup 321 into the feeding pipe 11 to complete the feeding of the reagent, and cooperating with the stirring mechanism 5 to work, so that the reagent and the contaminated water are fully mixed, and through the setting of the extension spring 324, the feeding cup 321 can be pulled back to below the feeding pipe 35 again through the rebound of the extension spring 324 after the feeding is completed, waiting for the next feeding, and through the setting of the push plate 323, the feeding pipe 35 can be closed by the push plate 323 when the feeding cup 321 moves away from the feeding pipe 35, to prevent the reagent from spilling out, through the cooperation of the feeding mechanism and the stirring mechanism 5, the reagent and the contaminated water can be uniformly mixed during stirring, thereby improving the accuracy and reliability of the detection result.

[0032] Wherein, when the driving gear 221 rotates, it will drive the connecting arm 231 to rotate, while the connecting arm 231 pushes the push plate 323, it will also drive the connecting arm 241 and the driven gear 24 to rotate through the telescopic column 232, but the driven gear 24 rotates reciprocatingly, since the teeth on the driven gear 24 engages with the engaging sheet 26, when the driven gear 24 rotates reciprocatingly, it will drive the connecting column 29 and the driven column 25 to lift, thereby driving the lower stirring mechanism 5 to lift, so that the stirring mechanism 5 covers the whole detection tank 1, through the setting of the driven gear 24, when the driving gear 221 rotates, it will drive the driven gear 24 to rotate reciprocatingly through the telescopic column 232 and other components, when it rotates reciprocatingly, it will drive the connecting column 29 and the driven column 25 to lift through the engaging sheet 26 and other components, thereby driving the stirring mechanism 5 to lift, improving the stirring effect, and through the setting of the spline groove 251, when the driven column 25 lifts up and down, it can also be driven to rotate by the spline gear 253.

[0033] The above has carried on the detailed explanation to one embodiment of the present application, but the content is only the preferred embodiment of the present application, cannot be considered for limiting the implementation scope of the present application. All equivalent changes and improvements made according to the scope of the present application application should still belong to the patent coverage scope of the present application.
