Figure 14(Illustration of the L direction in the diagram). When the telescopic spring is at its normal length, the ball 233 protrudes upwards (when the rotating bottle holder 42 is not rotating), which can obstruct a certain limiting tenon 43. When the rotating bottle holder 42 rotates, a limiting tenon 43 at the positioning seam D of the limiter 23 also rotates.

[0040] Reference Figures 1 to 15 In one embodiment, the implementation process of this utility model is as follows: S1. Three minutes before the scheduled time, the sampling pump 33 starts to pre-emptively drain the water supply pipeline 34; wherein, the diversion outlet 32 ​​opens the direct discharge port 321, and the water remaining in the water supply pipeline 34 is discharged into the wastewater receiving tray 48 through the direct discharge port 321 of the diversion outlet 32; wherein "before the scheduled time" means "before 0 minutes of each hour"; S2. One minute before the scheduled time, the control cabinet 25 activates the drive motor 44. The rotating part of the drive motor 44 rotates, driving the lever 453 to rotate. The rotation of the lever 453 drives a limit latch 43 at a set position. The limit latch 43 then drives the rotating bottle rack 42 to rotate step by step. After the "support 412 of the inverted cup rack 41 of the current station" is separated from the inverted cup guide rail 24, the "support of the inverted cup rack of the next station" is lifted along the inverted cup guide rail 24 to complete the set angle tilting, and drain the water from the bottle 5 on the support 412. As the lever 453 rotates, when the lever 453 passes the proximity switch 47, the proximity switch 47 detects the lever 453 and is triggered, causing the drive motor 44 to stop operating. Before the drive motor 44 stops operating, a limiting latch 43 passes through a limiter 23 at a set position to achieve precise positioning (i.e., reference). Figure 5 and Figure 14 A limiting tenon 43 will be engaged at the positioning seam D of the limiter 23 to achieve precise positioning. The inner cavity of the bottle 5 on the inverted cup holder 41 at the diversion outlet 32 ​​is precisely connected to the sampling output port 322. S3. When the time arrives on time, the diversion outlet 32 ​​switches from direct discharge to sampling output outlet. The sewage sample is accurately injected into bottle 5 from the sampling site (such as sewage well) via "water inlet 31 → water supply pipe 34 → sampling pump 33 → water supply pipe 34 → sampling output outlet 322". After 10 seconds of water injection, the system resets (reset means that the device enters standby mode and waits for the next operation).

[0041] Reference Figures 1 to 15 In one embodiment, the wastewater collection device 1 of this utility model achieves automatic bottle changing and accurate sampling through time-series control. Compared with manual sampling, this utility model can complete the collection of thirty sets of samples in 30 hours of operation (long-term operation), effectively reducing the intensity of manual labor and ensuring the standardized and safe sampling process.

[0042] The timing control function originates from the control cabinet 25, which integrates a PLC controller. The control program in the PLC controller is set with execution programs for "before and at the appointed time," including programs for pre-emption control of the water pipeline, water intake sampling control, conversion and diversion outlet channel control, and drive motor start and stop control. For example, the "start of drive motor 44" is controlled by the PLC controller to start at a set time. As another example, the "stop of drive motor 44" is triggered when lever 453 rotates past proximity switch 47. After proximity switch 47 senses the signal, it transmits a signal to the PLC controller. After receiving the signal from proximity switch 47, the PLC controller controls the drive motor 44 to stop running.

[0043] Other aspects of the wastewater collection device described in this utility model are found in the prior art and will not be repeated here.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
