[0036] Implementation Method 1

[0037] Reference Figures 1 to 4 This embodiment is an optional embodiment of this application, which discloses a sampling device for sewage, including a housing 1, on which a pumping module is provided, the pumping module including a peristaltic pump 7.

[0038] The sampling device also includes a water supply pipe 2. Along the length of the housing 1, a recovery tray 14 is provided on one side of the housing 1, and a water outlet pipe 12 is provided on the other side. The water supply pipe 2 is wound around the recovery tray 14, and the outlet end of the water supply pipe 2 passes through and is inserted into the housing 1, and is connected to the water outlet pipe 12. At the same time, the peristaltic pump 7 is connected to the section of the water supply pipe 2 located inside the housing 1 to realize the sewage extraction function.

[0039] A faucet 13 is also provided at the outlet of the water pipe 12; a sampling bottle is provided at the outlet of the faucet.

[0040] Furthermore, a retainer 15 is provided on the recycling tray 14. The retainer 15 is used to fix the inlet end of the water pipe 2, thereby realizing the storage of the water pipe 2, avoiding damage to the water pipe 2 and improving the aesthetics of the equipment.

[0041] Furthermore, a filter head 5 is provided at the inlet end of the water supply pipe 2. The filter head 5 includes a connector 501. One end of the connector 501 is connected to the inlet end of the water supply pipe 2 via a quick connector 502. The other end of the connector 501 is integrally connected to a filter disc 503. The filter disc 503 is coaxially connected to the connector 501, and the outer diameter of the filter disc 503 is 2-3 times the outer diameter of the connector 501.

[0042] The filter disc 503 has an opening at its free end, and a cover plate is threadedly connected to it. A filter screen 504 is provided on the cover plate.

[0043] The filter head 5 is designed to remove large-volume pollutants, preventing blockage of the water supply pipe 2 during the pumping process.

[0044] Furthermore, a number of counterweight rings 16 are fitted onto the insertion tube 501, and each of the counterweight rings 16 is provided with a locking screw 17 that is compatible with the insertion tube 501. It should be noted that the counterweight rings 16 are preferably made of corrosion-resistant high-density metals such as steel.

[0045] The counterweight ring 16 effectively increases the weight of the filter head 5, making it easier for the filter head 5 to sink below the liquid surface. Especially when there are a lot of floating objects on the water surface, the counterweight can ensure that the filter head 5 sinks stably to the bottom of the sewage surface, ensuring that the equipment can extract sewage normally and reducing the difficulty of sewage sampling.

[0046] Furthermore, a backwash water tank 8 is also provided inside the casing 1. A connecting pipe 9 is provided on the backwash water tank 8. A regulating valve 10 for controlling its on / off state is provided on the connecting pipe 9. A water supply pipe 11 is also provided on the top of the backwash water tank 8. The inlet end of the connecting pipe 9 is adapted to the inlet end of the water supply pipe 2.

[0047] When the equipment is finished or the sampling point needs to be changed, remove the filter head, then connect the water supply pipe 2 to the connecting pipe 9, open the regulating valve 10, and then turn on the peristaltic pump 7. The peristaltic pump 7 draws clean water from the backwash tank 8 to flush the water supply pipe 2. This not only reduces the difficulty of equipment maintenance, but also allows the sewage between multiple sampling points to be mixed, ensuring the accuracy of sampling.

[0048] Furthermore, a controller 6 is also provided on the chassis 1. The controller 6 includes a battery 601 and a main control switch. The battery 601 is electrically connected to the peristaltic pump 7 through the main control switch. The chassis 1 is also provided with a charging interface that is electrically connected to the battery 601.

[0049] It should be noted that a peristaltic pump 7 with a built-in controller 6 can also be selected; only the corresponding battery 601 needs to be provided.

[0050] Furthermore, the sampling device also includes a telescopic rod 4, which comprises several interlocking rods. A roller 18 is rotatably mounted on the last rod for the operator to hold. An adjusting rope 19 connected to the filter head 5 is wound around the roller 18. Guide rings 20 are also fitted on each of the rods. A connecting ring 21 is also provided on the filter disc 503. The adjusting rope 19 passes through each of the guide rings 20 in sequence and is connected to the connecting ring 21.

[0051] Preferably, the telescopic rod 4 is a fishing rod.

[0052] By using the telescopic rod and the adjusting rope together, the sampling range of the equipment is further expanded; at the same time, staff can also take samples from hidden drainage points at higher positions, reducing the difficulty of sewage sampling.

[0053] Secondly, the use of the adjustment rope not only expands the sampling range but also does not take up too much storage space, and its use is more flexible and versatile.

[0054] Compared with the prior art, this application realizes remote operation of sewage sampling by setting up a telescopic pole, eliminating the need for staff to go to the sewage sampling point to perform sewage sampling operations. Especially for sampling work in sewers or other hidden sewage discharge points, this application can reduce the sampling difficulty as much as possible.

[0055] Secondly, any area that the telescopic rod can reach can be used as a sampling point for the sampling bottle, thereby maximizing the sampling range and reducing the difficulty of sampling; at the same time, expanding the sampling points also helps to improve the accuracy of sampling.

[0056] Finally, since this application uses a pumping module for water pumping, wastewater sampling can be completed simply by placing the filter head below the wastewater surface. There is no need to control or adjust the position of the sampling bottle, which simplifies the wastewater sampling operation and further reduces the sampling difficulty.

[0057] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
