Four telescopic pins 92 are evenly distributed in a ring, and each of the four telescopic pins 92 is slidably connected by two sleeves and has a built-in telescopic spring. The upper surface of the counterweight 91 has an opening for liquid extraction. Four liquid collection tube assembly holes 93 and four sampling chambers 6 are arranged in a ring at equal intervals, with each liquid collection tube assembly hole 93 corresponding to a sampling chamber 6. An electrically controlled valve pipe 94 connects the liquid collection tube assembly holes 93 and the sampling chambers 6. A rotary motor 95 is fixedly connected to the center of the lower surface of the counterweight 91. A baffle 96 is fixedly connected to the output end of the rotary motor 95. A sampling port 97 is provided on the lower surface of the baffle 96. After the main body 1 is lowered to the required water depth sampling position via the liquid collection adjustment component 9, the device can be adjusted accordingly. The baffle 96 of the sampling port 97 is adjusted by rotating the rotary motor 95 to correspond to the sampling chamber 6, and the piston 8 is driven by the electric telescopic rod 7 to draw liquid into the sampling chamber 6.
