The second function is to cooperate with the flushing assembly 5 to quickly flush the inside of the sampling chamber 407 and the water quality sensor 409.

[0042] See the attached drawings in the specification Figure 7 and Figure 8As shown in the figure, the lifting assembly 3 includes a lifting box body 301. The lifting box body 301 is fixedly arranged on the monitoring platform 1 through a fixed bracket 305. A first winding and unwinding rope reel 302 is rotatably arranged in the lifting box body 301. A first motor 303 for driving it to rotate in the lifting box body 301 is arranged in the first winding and unwinding rope reel 302. Two winding and unwinding grooves 304 are axially formed on the outer side of the first winding and unwinding rope reel 302. A first lifting rope 306 is wound in each winding and unwinding groove 304. A rope passing hole 307 for passing through the two first lifting ropes 306 is formed at the bottom side of the lifting box body 301. The end of the first lifting rope 306 passes through the corresponding rope passing hole 307 and is fixedly connected to the top side of the box body 401. The output end of the digital display control panel 8 is electrically connected to the input end of the first motor 303. Through the above specific structural design, the two first lifting ropes 306 lift and lower the box body 401 in parallel, so as to ensure the stability of the vertical movement position of the box body 401. Cooperating with the guide wheel assembly 9, the cooperation insertion of the liquid injection pipe 506 and the docking guide hole 410 can be realized.

[0043] See the attached drawings of the specification Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown in the figure, the flushing assembly 5 includes a liquid delivery pump 501. The liquid delivery pump 501 is fixedly arranged on the fixed bracket 305. One end of a suction pipe 503 is connected to the liquid inlet of the liquid delivery pump 501.

In practical applications, the flushing assembly 5 is used to cooperate with the lifting assembly 3 to lift and lower the sampling box assembly 4, so as to realize the docking cooperation between the sampling box assembly 4 and the flushing assembly 5, thereby realizing the flushing of the sampling box assembly 4 by the flushing assembly 5. Under the mutual cooperation, flushing can be carried out after detecting water quality pollutants, so as to avoid affecting the detection accuracy.

[0044] See the attached drawings of the specification Figure 9 and Figure 10As shown in the figure, there are two guide wheel assemblies 9 distributed on both sides inside the monitoring cavity 101. The guide wheel assembly 9 includes a support frame 901 fixedly arranged on the inner side wall of the monitoring cavity 101. On one side of the support frame 901, there is a U-shaped wheel frame 903. Two V-shaped elastic pieces 902 are connected between the support frame 901 and the U-shaped wheel frame 903. A guide wheel 904 is rotatably arranged on the U-shaped wheel frame 903. An arc-shaped groove is formed on the outer side of the guide wheel 904 along its circumferential direction. In practical applications, when the lifting assembly 3 drives the sampling box assembly 4 to move up and down, it is inevitable that there will be a shaking situation. In order to ensure the docking and matching accuracy between the sampling box assembly 4 and the flushing assembly 5, the guide wheels 904 of the two guide wheel assemblies 9 can realize the up-and-down guiding movement of the box body 401. Especially under the elastic clamping action of the V-shaped elastic pieces 902, it can be ensured that when the box body 401 moves upward to be docked with the flushing assembly 5, the box body 401 does not shake in the left-right direction.

[0045] The anchor assembly 6 includes an anchor box 603 fixedly arranged on the inner side wall of the monitoring cavity 101. A second rope winding and unwinding disc 604 is rotatably arranged in the anchor box 603. A second motor 605 for driving it to rotate in the anchor box 603 is arranged inside the second rope winding and unwinding disc 604. A second lifting rope 601 is wound around the outer side of the second rope winding and unwinding disc 604. The end of the second lifting rope 601 passes through the anchor box 603 and is connected with a three-jaw anchor 602. The output end of the digital display control panel 8 is electrically connected to the input end of the second motor 605.

[0046] The buoyant airbag structure 2 includes an annular airbag 201 arranged outside the monitoring platform 1. A number of evenly distributed rings 203 are arranged on the annular airbag 201 along its circumferential direction. Each ring 203 is fixedly connected to the monitoring platform 1 through a connecting rope 202.

[0047] The working principle and technical effects of the present invention:

[0048] During use, the monitoring platform 1 floats on the water surface through the buoy airbag structure 2 and is fixed in position on the water surface by the anchor assembly 6. During sampling, the output shaft of the first motor 303 of the lifting assembly 3 rotates, driving the first winding and unwinding rope reel 302 to rotate within the lifting box body 301, thereby realizing the release of the first winding and unwinding rope reel 302, causing the sampling box assembly 4 to move downward in the water. The lifting assembly 3 can enable the sampling box assembly 4 to sample at different depths in the water. After the sampling box assembly 4 descends to the designated position, the push rod of the electric telescopic rod 405 extends, driving the lid 403 downward through the suspension rod 406, causing the lid 403 to separate from the sampling hole 402. Meanwhile, the piston guide rod 412 slides downward within the docking guide hole 410, causing the docking guide hole 410 to communicate with the sampling chamber 407 through the gas-liquid guide hole 411. As a result, the gas in the sampling chamber 407 bubbles upward through the gas-liquid guide hole 411 and the docking guide hole 410, and the water liquid enters the sampling chamber 407 through the sampling hole 402. Then, the push rod of the electric telescopic rod 405 resets, pulling the lid 403 to close the sampling hole 402. The sealing gasket 404 can tightly seal the sampling hole 402 by the lid 403, and at this time, the piston guide rod 412 seals the connection between the docking guide hole 410 and the gas-liquid guide hole 411. Then, the lifting assembly 3 lifts the sampling box assembly 4 upward above the water surface. During this process, the water quality sensor 409 can detect the water sample in the sampling chamber 407. After the detection is completed, the electric telescopic rod 405 drives the lid 403 downward, and the water sample falls out through the sampling hole 402. The lifting assembly 3 continues to drive the sampling box assembly 4 upward. The lower end of the liquid injection pipe 506 is inserted into the upper port inside the docking guide hole 410, and the sealing shoulder 508 abuts and seals with the upper port of the docking guide hole 410. The flushing assembly 5 sucks out the water liquid in the river water. After secondary filtration through the mesh box 504 and the filter box 505, it flushes the sampling chamber 407 and the water quality sensor 409 in the sampling chamber 407 through the liquid outlet pipe 502, the liquid injection pipe 506, the liquid guide notch 507, the docking guide hole 410, and the gas-liquid guide hole 411, thus not affecting the detection accuracy of the water quality for the next time.

[0049] As described above, this is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims described.
