[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-4 As shown, a wastewater sampling device for environmental protection includes a support plate 2, and a plurality of evenly distributed insertion rods 1 are fixedly connected to the bottom of the support plate 2.

[0028] The support plate 2 has a through hole at its center. A fixing cylinder 5 is fixedly installed at the top center of the support plate 2 by a plurality of evenly distributed fixing blocks. The bottom end of the fixing cylinder 5 extends into the through hole. A telescopic hose 9 is fixedly connected to the bottom end of the fixing cylinder 5. The bottom end of the telescopic hose 9 passes through the through hole.

[0029] The fixed cylinder 5 is equipped with an extraction component inside and a sampling component on its outer surface. During operation, the insertion rod 1 is first inserted into the support plate 2 at the location where sampling is required, and the flexible hose 9 is inserted into the sewage to facilitate the extraction component inside the fixed cylinder 5 to extract the sewage. After extraction, the sewage is sampled and processed by the sampling component, thus enabling the device to meet more usage needs and has strong practicality.

[0030] The extraction assembly includes a groove inside the fixed cylinder 5, with a piston 11 sliding inside the groove in a sealed manner. A through-hole extraction hole is formed on the lower surface of the groove, communicating with the interior of the telescopic hose 9. A through-hole is formed on the upper surface of the groove. An electric push rod 6 is fixedly installed at the top of the fixed cylinder 5, with its output end passing through the through-hole. A connecting rod 10 is fixedly connected to the output end of the electric push rod 6, and the bottom end of the connecting rod 10 is fixedly connected to the top of the piston 11. During operation, the electric push rod 6 drives the piston 11 to slide inside the groove, and the sliding of the piston 11 allows wastewater to be drawn into the groove through the telescopic hose 9 and the extraction hole, thus facilitating extraction.

[0031] The sampling assembly includes multiple sampling tubes 4 fixedly connected to the lower outer surface of the fixed cylinder 5 and evenly distributed. The sampling tubes 4 communicate with the inside of the chute through sampling holes 13. A filter box 3 is fixedly installed at one end of the sampling tube 4. An external threaded tube 23 is fixedly connected to the bottom of the filter box 3. A sampling bottle 12 is threadedly connected to the outer surface of the external threaded tube 23. During operation, the extracted sewage can be sampled through the sampling tubes 4, and the sampled sewage enters the sampling bottle 12 after being filtered by the filter box 3. This allows the same batch of samples to be distributed to multiple experimental containers for repeated testing or comparative analysis, making the detection data more accurate. At the same time, sewage can be sampled and placed in different places as needed, thus making the device more effective.

[0032] A valve 14 is fixedly installed on the outer surface of the sampling tube 4. The valve 14 and the electric push rod 6 are both electrically connected to the controller 7. A support rod 8 is fixedly connected between the filter box 3 and the fixed cylinder 5. During operation, the controller 7 controls the opening and closing of the valve 14, and the valve 14 can also control the opening and closing of the sampling tube 4. Therefore, after the sewage is extracted, the sampling tube 4 can be opened as needed to sample the sewage. At the same time, the controller 7 controls the progress of the electric push rod 6 and can control the sewage extraction.

[0033] The filter box 3 has a filter tank 16 inside. The filter tank 16 is connected to the sample tube 4 through a water inlet 15. The filter tank 16 is connected to the external threaded pipe 23 through a water outlet 22. A filter screen 19 is installed inside the filter tank 16. During operation, the wastewater inside the sample tube 4 enters the filter tank 16 through the water inlet 15, and the impurities in the wastewater are filtered by the filter screen 19. After filtration, the wastewater enters the sampling bottle 12 through the water outlet 22 and the external threaded pipe 23 to complete the sampling. At the same time, the impurities in the sampled wastewater are filtered by the filter screen 19 to avoid impurities affecting subsequent testing and to avoid affecting the sampling effect of the device.

[0034] A slot 17 is provided at the bottom inside the filter tank 16. One side of the slot 17 extends to the outside of the filter box 3. A mounting plate 18 is inserted into the slot 17. A mounting groove is provided inside the mounting plate 18. The filter screen 19 is fixedly connected inside the mounting groove. One side of the mounting plate 18 extends to the outside of the filter box 3. A handle plate 20 is fixedly connected to one side of the mounting plate 18. During operation, the filter screen 19 is fixedly installed through the mounting groove inside the mounting plate 18. Since the mounting plate 18 is inserted into the slot 17, the handle plate 20 facilitates the removal and disassembly of the mounting plate 18 and the filter screen 19 from the filter tank 16, and also facilitates the disassembly and cleaning of the filter screen 19.

[0035] Both sides of the handle plate 20 are fixedly connected by mounting bolts 21, which are threaded to the filter box 3. A handle 24 is fixedly connected to the center of one side of the handle plate 20. During operation, the mounting bolts 21 facilitate the installation and disassembly of the handle plate 20, the mounting plate 18, and the filter box 3, and also facilitate the disassembly, cleaning, and installation of the filter screen 19. The handle 24 facilitates the removal of the handle plate 20 and the mounting plate 18, thus enabling the device to meet more usage needs and making it highly practical.
