[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 6 As shown, the aquaculture water quality sampler of this utility model includes a column 1; a disc 11 is fixedly connected to the top of the column 1; a set of first cavities 12 are formed inside the column 1; a set of first through holes 15 are formed on the outer wall of the column 1, and the first through holes 15 and the first cavities 12 are interconnected, with the first through holes 15 located below the bottom of the first cavities 12; a piston 14 is slidably connected to the first cavity 12; a set of pistons 14 are connected by a lifting column 13, and the top of the lifting column 13 penetrates the column 1 and the disc 11; the lifting column 13 moves up and down by a lifting component; a first pipe 16 is fixedly connected to the outer wall of the column 1, and the first through hole 15 is connected to the disc 11. A pipe 16 and a first through hole 15 are interconnected; a handle 17 is fixedly connected to the outer wall of the disc 11; in the prior art, when testing the water quality of aquatic products, it is necessary to sample the water quality at different depths, but the existing device requires multiple operations to complete the sampling, and cannot sample at one time, resulting in low water quality sampling efficiency; therefore, in operation, the present invention places the column 1 into the water body of the aquatic product, and then drives the lifting column 13 to move upward through the lifting component. At this time, the piston 14 slides upward in the sealed first cavity 12, and water is introduced through the first pipe 16 and the first through hole 15. Then the entire device is removed, which can sequentially extract water quality samples at different depths, ensuring sampling efficiency.

[0025] The lifting component includes a threaded sleeve 2; the threaded sleeve 2 is fixedly connected to the middle of the disc 11, and the top of the lifting column 13 is located inside the threaded sleeve 2; a threaded column 21 is rotatably connected to the lifting column 13, and the threaded column 21 is threadedly connected inside the threaded sleeve 2; the threaded column 21 is rotated by a power component.

[0026] The power component includes a ring gear 22; the top end of the threaded sleeve 2 is rotatably connected to the ring gear 22; a pair of symmetrically distributed first sliding grooves 23 are provided on the outer wall of the threaded column 21; a pair of symmetrically distributed first sliders 24 are fixedly connected to the inner wall of the ring gear 22, and the first sliders 24 are slidably connected in the first sliding grooves 23; a servo motor 25 is fixedly connected to the top end of the disk 11, and the output end of the servo motor 25 is provided with a first rotating shaft 26; a first gear 27 is fixedly connected to the top end of the first rotating shaft 26, and the first gear 27 and the ring gear 22 mesh with each other; a cover is fixedly connected to the top end of the disk 11; the top end of the threaded column 21 passes through and extends out of the cover.

[0027] During operation, the servo motor 25 operates, which in turn drives the ring gear 22 to rotate via the first gear 27. The rotation of the ring gear 22 causes the first slider 24 and the first slide groove 23 to rotate the threaded column 21, which in turn moves the threaded column 21 upward, which in turn moves the lifting column 13 upward. The upward movement of the lifting column 13 moves the piston 14 upward, thereby performing the sampling operation. A filter screen can be installed on the first pipe 16, which is not described in the existing technology.

[0028] The column 1 has a cut-off cavity 3, which cuts off the first through hole 15; a cut-off plate 31 is slidably connected in the cut-off cavity 3, and a second through hole 32 is provided in the cut-off plate 31; the cut-off plate 31 moves up and down through a tension member.

[0029] The tensioning member includes an inverted L-shaped plate 33; the top of the cover cylinder is fixedly connected to the inverted L-shaped plate 33 by a spring, and the vertical rod of the inverted L-shaped plate 33 passes through the cover cylinder, the disc 11 and the column 1 and extends into the cut-off cavity 3, while the bottom end of the vertical rod of the inverted L-shaped plate 33 is fixedly connected to the top of the cut-off plate 31; during operation, the top of the horizontal plate of the inverted L-shaped plate 33 is fixedly connected to a pull ring 34;

[0030] A sample bottle 35 is provided on the outer wall of the column 1; the opening of the sample bottle 35 is threadedly connected to the outer wall of the first pipe 16;

[0031] During operation, after sampling, the pull ring 34 on the inverted L-shaped plate 33 is released, allowing the inverted L-shaped plate 33 to move down, which in turn allows the cut-off plate 31 to move down, causing the second through hole 32 and the first through hole 15 to be misaligned, thus blocking the first through hole 15. Then, the column 1 is removed, and sample bottles 35 are installed on each first pipe 16. The column 1 is placed horizontally, and the pull ring 34 is pulled to connect the second through hole 32 and the first through hole 15. Then, the servo motor 25 is rotated in the opposite direction, causing the piston 14 to move down, thus squeezing out the sample water in the first cavity 12 and completing the sampling operation.

[0032] Working principle: The column 1 is placed into the aquatic water, and then the lifting column 13 is moved upward by the lifting component. At this time, the piston 14 slides upward in the sealed first cavity 12, and water is introduced through the first pipe 16 and the first through hole 15. Then the entire device is taken out. It can take water samples at different depths in sequence to ensure sampling efficiency. The servo motor 25 works, which drives the ring gear 22 to rotate through the first gear 27. The rotation of the ring gear 22 causes the first slider 24 and the first sliding groove 23 to drive the threaded column 21 to rotate, which in turn drives the threaded column 21 to move upward, which in turn drives the lifting column 13 to move upward. The piston 14 moves upward, causing the piston 13 to move upward, thus performing the sampling operation. After sampling, the pull ring 34 on the inverted L-shaped plate 33 is released, allowing the inverted L-shaped plate 33 to move downward, which in turn allows the cut-off plate 31 to move downward, causing the second through hole 32 and the first through hole 15 to be misaligned, thus blocking the first through hole 15. Then, the column 1 is removed, and a sample bottle 35 is installed on each first pipe 16. The column 1 is placed horizontally, and the pull ring 34 is pulled to connect the second through hole 32 and the first through hole 15. Then, the servo motor 25 is rotated in the opposite direction, causing the piston 14 to move downward, thus squeezing out the sample water in the first cavity 12, thus completing the sampling operation.
