[0030] In order to facilitate sampling of distant water bodies, such as the Figures 1 to 9As shown, the present application adopts the following structure. Through the arrangement of the handle 1, the guide rail 6, the elastic bow 13, the elastic rope 14, the push plate 15, the winding roller 19, the fishing line 20 and the sampling tank 21, the water sample collection device for basic water resource survey has the effect of facilitating sampling of distant water bodies. When in actual use, the opening angle of the elastic bow 13 is adjusted according to the position of the water body to be sampled, and then the limit block 16 is clamped on the upper end of the connecting plate 17, and then the rotating plate 29 is pressed and rotated. When the fishing line 20 is wound around the outer surface of the winding roller 19, the fishing line 20 is tightened and the right end of the sampling tank 21 is pressed against the right side of the push plate 15. Then, the rocker 31 is released. At this time, the rotating plate 29 is ejected by the spring, so that the limiting tooth 30 is disengaged from the limiting groove 27. The winding roller 19 can rotate freely, and then the trigger 2 is pulled, and the inclined surface of the right end of the push rod 3 squeezes the slider 4, causing the slider 4 to move downward, driving the U-shaped limit pin 7 to drop, and then the upper end of the U-shaped limit pin 7 is disengaged from the card connection with the limit block 16, and then the sampling tank 21 is launched along the left end of the guide rail 6, and then the sampling tank 21 falls into the designated position of the water body to be sampled, and is sunk into the water body by the counterweight block 24.

After the sampling is completed, the fishing line 20 is contracted by squeezing and rotating the rocker 31, thereby retracting the sampling tank 21 and completing the sampling. That is, through the coordinated arrangement of the handle 1, the guide rail 6, the elastic bow 13, the elastic rope 14, the push plate 15, the winding roller 19, the fishing line 20 and the sampling tank 21, the sampling tank 21 can be launched to a distant location during use to sample the water body, thereby achieving the purpose of facilitating the sampling of distant water bodies;
[0031] Example 2
[0032] The utility model provides a technical solution: the lower surface of the guide rail 6 is slidably connected to an adjusting block 9, the upper surface of the adjusting block 9 is fixedly connected to a limiting shaft 10, the outer surface of the limiting shaft 10 is fixedly connected to a sliding gasket 11, the upper end of the limiting shaft 10 is rotatably connected to a connecting rod 12, the lower surface of the adjusting block 9 is threadedly connected to an adjusting knob 34, the inner side wall of the adjusting block 9 is slidably connected to a limiting block 33, and the lower surface of the guide rail 6 is fixedly connected to a rack 32.
[0033] In order to facilitate the adjustment of the ejection distance of the sampling tank 21, as shown in the attached Figures 1 to 9As shown, the present application adopts the following structure. Through the arrangement of the adjustment block 9, the limit shaft 10, the connecting rod 12, the elastic bow 13, the rack 32, the limit block 33 and the adjusting knob 34, the water sample collection device for the basic water resource survey has the effect of facilitating the adjustment of the ejection distance of the sampling tank 21. In actual use, the angle of the elastic bow 13 can be adjusted according to the distance of the water body to be sampled. When adjusting, the adjusting knob 34 is loosened. At this time, the limit block 33 descends, thereby driving the limit block 33 to descend and disengage from the engagement with the rack 32. The adjustment block 9 is slid left and right. At this time, the angle of the elastic bow 13 can be adjusted by driving the connecting rod 12. The larger the opening angle of the elastic bow 13, the greater the tension on the elastic rope 14 when the push plate 15 is stretched to the right end, and the greater the elastic force when released, and vice versa. After adjusting to the appropriate position, tighten the limit block 33 so that the limit block 33 is stuck in the interior of the rack 32, and the position of the adjustment block 9 is fixed, thereby completing the adjustment. Through the coordinated arrangement of the adjustment block 9, the limit shaft 10, the connecting rod 12, the elastic bow 13, the rack 32, the limit block 33 and the adjustment knob 34, the opening angle of the elastic bow 13 can be adjusted during use, thereby adjusting the elastic force of the elastic rope 14, thereby achieving the purpose of facilitating the adjustment of the ejection distance of the sampling tank 21.
