At the same time, when the top cover moves upward, the telescopic rod will also move in the telescopic cylinder and stretch the spring. After pulling the connecting rope for a while to allow the water to be tested to enter the sampling box through the water inlet, the pulling block is released. The stretched spring will shrink and reset and pull the top cover back into the sampling box, and the top of the sampling box will be re-sealed.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] 1. In the present invention, when sampling water sources at different depths, the rotating rod can be rotated to drive the screw rod to rotate.

Then, one of the pulling blocks is pulled to pull the top cover above one of the sampling boxes upward through the connecting rope, so that the water inlet hole opened on the side of the top cover leaks out. At the same time, when the top cover moves upward, the telescopic rod will also move in the telescopic cylinder and stretch the spring. After pulling the connecting rope for a period of time, the water to be tested will pass through. After entering the sampling box through the water inlet, release the pulling block, and the stretched spring will shrink and reset and pull the top cover back into the sampling box, re-seal the top of the sampling box, and turn the rotating rod again to control the remaining sampling boxes to extend into other water depths for sampling. With this method, when the device is sampling, it only needs to control the depth of the sampling box inserted into the water and pull the corresponding connecting rope to open the top cover, so that multiple waters of different depths can be sampled in one sampling operation, thereby improving the efficiency of the sampling work.

[0024] 2. In the present invention, when the liquid in the sampling box needs to be taken out after the sampling work is completed, the end of the connecting rope can be pulled out from the inside of the buckle block, and then the sampling box can be pulled sideways to slide the buckle on the side of the sampling box out of the buckle groove. At this time, the sampling box can be disassembled, and then the sealed cover at the bottom of the sampling box can be pulled out to discharge the collected liquid for testing. Through this method, the sampling box can be quickly removed from the mounting base after the device completes the collection work, thereby improving the efficiency of subsequent testing work.
