Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings:

[0039] The first embodiment provides a wastewater sampling device 1 for environmental monitoring, such as... Figures 1-7 As shown, the device includes a robotic arm 5, a sampling head 37, a base frame 12, and a support 11 mounted on the upper side of the base frame 12. A container rack 2 is mounted on the base frame 12, and multiple containers 21 are spaced apart on the container rack 2. The robotic arm 5 is mounted on the support 11, and a pressure block 56 is mounted on the output end of the robotic arm 5. A positioning groove 561 that mates with the container 21 is mounted on the lower side of the pressure block 56. A first insertion pin 57 is mounted on the pressure block 56. A counterweight ring 372 is mounted on the sampling head 37. One end of the sampling head 37 is connected to the first insertion pin 57 via a second pump 35.

[0040] The robotic arm 5 places the pressure block 56 onto the corresponding container 21, and the sampling head 37 is dropped into the sewage. Under the action of the counterweight ring 372, the sampling head 37 can be lowered into the deeper sewage, which is convenient for sampling operation. Then, the second pump 35 sucks the sewage into the container 21 to realize sewage sampling, which is convenient for subsequent sewage environmental protection testing. Multiple water samples can be stored at the same time.

[0041] The robotic arm 5 can be a commercially available product. A camera 15 can be mounted on the support frame 11. A power distribution box 6 is also mounted on the base frame 12 for power supply.

[0042] The second embodiment provides a specific structure for the robotic arm 5, such as... Figure 1 and Figure 2 As shown, it includes a first linear module 51, a second linear module 52, and a longitudinal driver 55; the first linear module 51 is mounted on the bracket 11; the second linear module 52 is mounted on the output end of the first linear module 51, the longitudinal driver 55 is mounted on the output end of the second linear module 52, and the pressure block 56 is mounted on the output end of the longitudinal driver 55.

[0043] The first linear module 51 and the second linear module 52 can be commercially available products. Linear movement is achieved through the cooperation of a lead screw and a nut; the specific structure will not be described in detail here. The movement directions of the first linear module 51 and the second linear module 52 are horizontal and perpendicular. The second linear module 52 can be connected to the longitudinal driver 55 via a connector.

[0044] In the third embodiment, unlike the second embodiment, the robotic arm 5 further includes a second mounting base 534, a mounting plate 536, and multiple sets of linkage assemblies 53 spaced apart on the mounting plate 536, such as... Figure 2 The linkage assembly 53 includes a third motor 531, a first link 532, and a second link 533. A mounting plate 536 is disposed at the output end of the second linear module 52. The third motor 531 is mounted on the mounting plate 536, and the upper end of the first link 532 is connected to the output end of the third motor 531. The upper end of the second link 533 is hinged to the lower end of the first link 532. The lower end of the second link 533 is hinged to a second mounting base 534, and a longitudinal driver 55 is mounted on the second mounting base 534. The height of the second mounting base 534 and the longitudinal driver 55 can be adjusted by using multiple linkage assemblies 53, improving adaptability.

[0045] Fourth embodiment, such as Figure 3 As shown, the inner wall of the positioning groove 561 is inclined, and a rubber cap 22 is provided at the upper end of the container 21. The positioning groove 561 matches the rubber cap 22, facilitating the receipt of the rubber cap 22 from the container 21 during the pressing process. Specifically, the cross-section of the positioning groove 561 gradually increases downward. Meanwhile, the pressing block 56 is provided with a first pin 57 and a second pin 58 at intervals. The first pin 57 is used for liquid inlet, and the second pin 58 is used for pressure balance within the container 21. That is, channels are respectively provided within the first pin 57 and the second pin 58. The pressing block 56 presses against the rubber cap 22 through the positioning groove 561, and the lower end of the first pin 57 pierces the rubber cap 22 and extends into the container 21.

[0046] Optionally, a partition 24 is provided inside the container rack 2; a first mounting base 23 is provided at the bottom of the container rack 2, and the container 21 is detachably mounted on the first mounting base 23.

[0047] Fifth embodiment, such as Figure 2 and Figure 6 A receiving groove 111 is provided on one side of the bracket 11 to cooperate with the sampling head 37. The sampling head 37 is detachably installed in the receiving groove 111, specifically, the receiving groove 111 is engaged within the receiving groove 111. The sampling head 37 also contains a water immersion sensor 38 and a filter 39. The water immersion sensor 38 can detect the entry of the sampling head 37 into wastewater, and the filter 39 is used to filter large particulate impurities to prevent clogging.

[0048] The sampling head 37 is connected to the input end of the second pump 35 via the sampling tube 371, and the sampling tube 371 is wound up or stored inside the bracket 11. The sampling tube 371 may be provided with a length scale (not shown in the figure) to facilitate reading the height or depth of the sampling head 37 when it is lowered.

[0049] The sixth embodiment, as follows: Figure 7 The support frame 11 also houses a first pump 31 and a clean water tank 25. The input end of the first pump 31 is connected to the output end of the clean water tank 25, and the output end of the first pump 31 is connected to the input end of the second pump 35 via a check valve 32. After sampling, the first pump 31 and the second pump 35 are turned on to flush the pipeline. More specifically, the container rack 2 also houses a wastewater tank 26. After the mechanical arm 5 presses the pressure block 56 onto the wastewater tank 26, the first pump 31 and the second pump 35 are turned on. Part of the flushing water enters the wastewater tank 26, and the other part of the flushing water is discharged from the sampling head 37. The sampling head 37 can be placed in an external location or in a drainage tank (not shown).

[0050] Figure 7 The diagram also shows a control module 4, which is connected to the camera 15, the immersion sensor 38, the control terminal of the robotic arm 5 and its longitudinal actuator 55, and the control terminals of the first pump 31 and the second pump 35. The control module 4 can be a PC or a circuit board based on an ARM or STM32 microprocessor, used to receive data and control the operation of the robotic arm 5 and the first and second pumps 31 and 35. The control method is existing technology and will not be described further in this invention.

[0051] This invention utilizes the cooperation of a robotic arm 5, a second pump 35, and a sampling head 37 to dispense different water samples into corresponding containers 21. Furthermore, the cooperation of a clean water tank 25, a first pump 31, and a wastewater tank 26 flushes the pipeline, preventing cross-contamination between samples and improving the accuracy and effectiveness of subsequent testing.

[0052] The specific testing method includes the following steps:

[0053] Step 101: Using the robotic arm 5, the pressure block 56 is pressed into the rubber stopper of the first container, while the first pin 57 and the second pin 58 are connected to the space inside the first container.

[0054] Step 102: After placing the sampling head 37 at the corresponding sampling location, turn on the second pump 35 to pump the sewage in the sampling location into the first container.

[0055] More specifically, the signal fed back by the immersion sensor 38 can determine whether the sampling head 37 has entered the sewage. If it has not entered the sewage, the second pump 35 can be refused to be turned on.

[0056] If the sampling location is the same but the sampling depth is different, proceed to step 103: After sampling, turn off the second pump 35 and press the pressure block 56 into the second container using the robotic arm 5; after adjusting the depth of the sampling head 37, turn on the second pump 35 to perform sampling.

[0057] If the sampling location or sampling point is different, proceed to step 104: After sampling, if 500-1000ml of sample has been collected, turn off the second pump 35 and press the pressure block 56 into the sewage tank 26 using the robotic arm 5.

[0058] Step 105: After placing the sampling head 37 into the external drain tank, turn on the first pump 31 and the second pump 35 to flush the pipeline and the sampling head 37. The specific flushing volume is 200-1000ml.

[0059] Step 106: After rinsing, turn off the first pump 31 and the second pump 35, and then use the robotic arm 5 to press the pressure block 56 into the second container to execute step 102.

[0060] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
