[0002] Cylindrospora toxins in natural water bodies are toxic compounds produced by certain freshwater algae (such as Cylindrospora), which pose a serious threat to human and animal health. In recent years, with the intensification of eutrophication of water bodies, the problem of algal toxin pollution caused by abnormal reproduction of algae has become increasingly serious, and cylindrospora toxins are one of them. In order to ensure the safety of water quality and human health, it is necessary to detect the concentration of cylindrospora toxins in the water body. In the process of cylindrospora toxin concentration detection, water from natural water bodies is generally collected through sampling equipment, and the sampled water is detected by detection instruments to obtain the cylindrospora toxin concentration contained in the water. In the sampling process, the inlet end (pipeline) of the sampling equipment is generally placed directly in the water body. Since there are impurities floating on the surface of the natural water body, some of the floating impurities will enter the sampling equipment, which may easily cause the sampling equipment and even the detection instrument to be blocked or damaged, affecting the speed of detecting the cylindrospora toxin concentration.

[0029] First, move the telescopic tube 4 and extend it, insert the side of the separation box 5 with the opening 15 into the sampling water body (the opening 15 faces downward, and a part of the separation box 5 is immersed in the water), then rotate the movable end of the telescopic tube 4 to rotate with the separation box 5. Since the connecting rod 9 does not rotate, the separation box 5 rotates relative to the scraper 11, and the scraper 11 is used to sweep away the impurities on the side of the opening 15 of the separation box 5 (because the separation box 5 is inserted into the sampling water body, it will press down some floating objects on the water surface and make them gather around the opening 15), and the flexible connector 19 is wrapped around the outer wall of the connecting rod 9 to pull the baffle 16 to move until the opening 15 is aligned with the through hole 17, and the opening 15 is opened;

[0030] Second, pump 2 operates, allowing water from the sampled water body to enter the interior of storage tank 1 through opening 15, through hole 17, separation box 5, and telescopic tube 4. When a certain amount of water sample is collected, pump 2 stops operating. Detection equipment 3 is used to extract water from storage tank 1 and conduct a test to determine the concentration of cylindrosporin toxins in the natural water body.

[0031] It should be noted that a filter is installed between the connection area of ​​the telescopic tube 4 and the pump 2 to further filter impurities.

The first pipe 41 is connected to the pump 2, and the end of the second pipe 42 away from the first pipe 41 is inserted into the separation box 5. One end of the connecting rod 9 is fixedly installed in the inner cavity of the mounting sleeve 10.

Under the action of the elastic element, the limit block 25 is inserted into the slot 22 to fix the kit 21. When the separation box 5 continues to rotate, the flexible connector 19 will be wrapped around the outer wall of the kit 21 to drive the baffle 16 to move to open the opening 15; so that the scraper block 11 rotates for a period of time, and then the baffle 16 moves to open the opening 15, so that the scraper block 11 can first clean the impurities at the opening 15, further reducing the chance of floating impurities entering the separation box 5.

[0035] It should be noted that a pull block is installed on the side wall of the limit block 25, and the end of the pull block away from the connecting rod 9 extends to the outside of the connecting rod 9; pulling the pull block on the outside of the connecting rod 9 moves the limit block 25 and removes it from the slot 22 to drive the limit block 25 to reset.

[0037] It should be noted that the stopper 13 is installed in the inner cavity of the separation box 5 , and a balance pipe (hard pipe) communicating with the air vent 12 is installed on the outer side wall of the separation box 5 .

[0038] In this embodiment, as a further optimization solution, please refer to Figure 1 The concentration detection device also includes a vehicle body 6, on which the storage tank 1 and the detection equipment 3 are both arranged, so as to facilitate the movement of the concentration detection device outdoors.
