[0025] See also Figure 1-4 , a water sampling device for environmental assessment detection, comprising a sampling box 1, a sampling component is arranged inside the sampling box 1, and a cleaning component is arranged on one side of the outer surface of the sampling box 1;

[0026] The sampling component includes a plurality of sample storage bins 3, and the plurality of sample storage bins 3 are all opened inside the sampling box 1, a sealing ring 305 is slidably embedded inside the plurality of sample storage bins 3, and a sealing plate 304 is fixedly installed inside the plurality of sealing rings 305, a column 301 is fixedly installed on the top of the outer surface of the plurality of sealing plates 304, and a pressure plate 302 is fixedly installed on the top of the outer surface of the plurality of columns 301, a plurality of sampling springs 303 are fixedly installed on the bottom of the outer surface of the pressure plate 302, and the plurality of sampling springs 303 are wound and sleeved on the outer surface of the column 301;

[0027] The cleaning component includes a sampling plate 5, and cleaning grooves 501 are opened on both sides of the inner wall of the sampling plate 5, and sliding columns 502 are fixedly installed inside the multiple cleaning grooves 501, and sliders 504 are slidably sleeved on the outer surfaces of the multiple sliding columns 502 near the top, and cleaning springs 503 are fixedly installed on the bottoms of the outer surfaces of the multiple sliders 504, and the multiple cleaning springs 503 are wrapped and sleeved on the outer surfaces of the sliding columns 502, and a cleaning plate 505 is provided on one side of the outer surfaces of the multiple sliders 504.

[0028] Through the above technical scheme, the sampling plate 5 is vertically placed into the liquid to be sampled through the handle 11. After it is placed to an appropriate depth, the pressing plate 302 is pressed. The pressing plate 302 drives the column 301 to move downward. The column 301 drives the sealing plate 304 to move while moving downward. The sealing plate 304 squeezes the air in the sample storage chamber 3 to discharge the air. After the sealing plate 304 moves to the bottom of the sample storage chamber 3, the sampling spring 303 is reset and pushes the pressing plate 302 to move upward. While the pressing plate 302 moves, it drives the sealing plate 304 to move through the column 301 to extract the liquid to be sampled. After the extraction is completed, the second valve 8 can be rotated to close the second valve 8 to prevent the sampled liquid from flowing out. When necessary, the seal of the discharge pipe 7 can be released by opening the first valve 6, and the pressing plate 302 can be pressed again to make the liquid flow out of the discharge pipe 7 for detection.

[0029] Through the above technical solution, when debris accumulates on the surface of the filter plate 12 and affects the sample water collection effect, the cleaning plate 505 can be dragged downward. A cleaning brush is arranged on the inner side of the cleaning plate 505. The movement of the cleaning plate 505 drives the cleaning brush to move to clean the surface of the filter plate 12. At the same time, the movement of the cleaning plate 505 drives the slider 504 to slide on the outer surface of the sliding column 502. The slider 504 squeezes the cleaning spring 503 while sliding. When the cleaning plate 505 moves to the bottom of the sliding column 502, the cleaning spring 503 is reset and drives the cleaning plate 505 to rise, so that the cleaning plate 505 is fixed in a specific position to avoid the cleaning plate 505 blocking the filter plate 12 and affecting the sampling efficiency.

[0030] Specifically, a cover plate 2 is slidably sleeved on the outer surfaces of the plurality of columns 301 near the bottom, and a plurality of threaded rods 4 are rotatably embedded inside the cover plate 2 . The plurality of threaded rods 4 penetrate the cover plate 2 and are threadedly embedded inside the sampling box 1 .

[0031] Through the above technical solution, the cover plate 2 seals the sampling box 1, and the threaded rod 4 connects the cover plate 2 and the sampling box 1 together. When necessary, the cover plate 2 can be removed by rotating the threaded rod 4.

[0032] Specifically, a plurality of discharge pipes 7 are fixedly installed on one side of the outer surface of the sampling box 1 , and a first valve 6 is fixedly installed on the outer surfaces of the plurality of discharge pipes 7 .

[0033] Through the above technical solution, the sampled liquid is collected through the discharge pipe 7, and the first valve 6 can close the discharge pipe 7.

[0034] Specifically, a plurality of telescopic tubes 9 are fixedly installed on the bottom of the outer surface of the sampling box 1 , and a second valve 8 is fixedly installed on the outer surfaces of the plurality of telescopic tubes 9 .

[0035] Through the above technical solution, the telescopic tube 9 transports the sampled liquid, and the telescopic tube 9 can be sealed by the second valve 8.

[0036] Specifically, the sides of the multiple telescopic tubes 9 away from the second valve 8 are fixedly connected to the sampling plate 5 , and the sampling plate 5 is provided with multiple bases 10 inside.

[0037] Through the above technical solution, the sampling plate 5 is placed in the liquid to be sampled to collect the liquid, and the base 10 is convenient for collecting liquids at different depths.

[0038] Specifically, filter plates 12 are fixedly installed inside the plurality of bases 10 .

[0039] Through the above technical solution, the filter plate 12 filters the collected liquid sample to prevent impurities from mixing into the sample and affecting the detection effect.

[0040] Specifically, a handle 11 is fixedly installed on the top of the outer surface of the sampling plate 5 , and a base 10 is fixedly installed on the bottom of the outer surface of the sampling box 1 .

[0041] Through the above technical solution, the handle 11 facilitates the operation of the sampling plate 5, and the base 10 supports the device.

[0042] When in use, the sampling plate 5 is placed vertically into the liquid to be sampled through the handle 11. After it is placed to a suitable depth, the pressing plate 302 is pressed. The pressing plate 302 drives the column 301 to move downward. The column 301 drives the sealing plate 304 to move while moving downward. The sealing plate 304 squeezes the air in the sample storage chamber 3 to discharge the air. After the sealing plate 304 moves to the bottom of the sample storage chamber 3, the sampling spring 303 is reset to push the pressing plate 302 to move upward. The pressing plate 302 drives the sealing plate 304 to move through the column 301 to extract the liquid to be sampled. After the extraction is completed, the second valve 8 can be rotated to close the second valve 8 to prevent the sampled liquid from flowing out. When necessary, the discharge pipe can be released by opening the first valve 6. 7, press the pressure plate 302 again to make the liquid flow out of the discharge pipe 7 for testing the liquid. When debris accumulates on the surface of the filter plate 12 and affects the sample water collection effect, the cleaning plate 505 can be dragged downward. A cleaning brush is arranged on the inner side of the cleaning plate 505. The movement of the cleaning plate 505 drives the cleaning brush to move to clean the surface of the filter plate 12. At the same time, the movement of the cleaning plate 505 will drive the slider 504 to slide on the outer surface of the sliding column 502. The slider 504 will squeeze the cleaning spring 503 while sliding. When the cleaning plate 505 moves to the bottom of the sliding column 502, release your hand and the cleaning spring 503 resets to drive the cleaning plate 505 to rise, so that the cleaning plate 505 is fixed in a specific position to avoid the cleaning plate 505 blocking the filter plate 12 and affecting the sampling efficiency.
