A cross plate is fixed to the outer wall of the fixed rod near the top by screws, and a through hole is opened on one side of the cross plate. A pressing rod is slidably connected to the inner wall of the through hole. A return spring is fixed to the outer wall of the cross plate at the through hole. A convex block is provided near the top of the outer wall of the pressing rod, and the top end of the return spring is fixed to the bottom of the convex block. A sampling unit is fixed to the outer walls of the fixed rod and the pressing rod by bolts. The sampling unit includes a first fixed block. The utility model realizes the operation of sampling at different depths of water level at one time. The sampling quantity and height can be adjusted according to the actual situation, and the adjustment method is simple. The sampling process can be completed only by pressing the handle. The sampling is convenient and has strong practicability, effectively controlling the experimental variables and providing guarantee for the accuracy of experimental data.

[0003] During the use of this patent, the staff arranges and fixes the sampling boxes at equal intervals on the fixed rod and inserts it into the water to sample the water. Since the positions of the sampling boxes are fixed and the sampling depth is limited, the staff cannot adjust the positions of the sampling boxes in the water, so sampling at deeper depths cannot be carried out. For this reason, we propose a mobile biological sample collection device to solve the problems raised in the above background technique. Content of the Utility Model

The cross partition board 2 divides the internal space of the tube body 1 into four adjustment cavities 3. A drive motor 4 is fixedly installed at the position corresponding to the adjustment cavity 3 at the top of the tube body 1. The output shaft of the drive motor 4 penetrates into the adjustment cavity 3 and is fixedly connected with a screw rod 5. The screw rod 5 is provided with anti-rust paint to prevent rust caused by long-term immersion in water, which affects the screw drive. A lifting block 6 is threadedly connected to the screw rod 5 along the axial direction. A connecting rod 7 is fixedly connected to the outer surface of the lifting block 6. The tube body 1 is provided with a guiding through groove 8 communicating with the adjustment cavity 3 at the position corresponding to the connecting rod 7. One end of the connecting rod 7 penetrates outside the guiding through groove 8 and is fixedly connected with a sample collection component 9.

The sealing sleeve 96 is sleeved on the left end of the feed pipe 93. A valve 97 is installed on the discharge pipe 94.

[0022] Specifically, a first sealing ring 98 is fixedly connected to the left side of the partition plate 92 corresponding to the telescopic end of the electric push rod 95. The first sealing ring 98 can prevent the sampled water from infiltrating through the gap between the partition plate 92 and the telescopic end of the electric push rod 95. A second sealing ring 10 is fixedly connected to the top inner wall of the adjusting cavity 3 corresponding to the output shaft of the driving motor 4. The second sealing ring 10 can prevent water from infiltrating through the gap between the output shaft of the driving motor 4 and the adjusting cavity 3.

[0023] Specifically, an annular insertion plate 99 is fixedly connected to the inner wall of the sealing sleeve 96. The annular insertion plate 99 is inserted into the left end of the feed pipe 93. The annular insertion plate 99 can effectively improve the sealing degree between the sealing sleeve 96 and the feed pipe 93, and prevent water from infiltrating into the collection box 91 when the pipe body 1 is inserted into the water.

[0024] Specifically, four legs 11 are equidistantly and circumferentially installed on the surface of the pipe body 1 near the bottom. When it is necessary to take out the sampled water in the collection box 91, it can stably support the pipe body 1, facilitating the water intake work.

[0025] Specifically, a vertical rod 12 is fixedly installed at the central position of the top of the pipe body 1. The length of the pipe body 1 is 1 - 5 m. According to the length of the pipe body, corresponding components can be installed at the top of the vertical rod 12.

[0027] During use, after the pipe body 1 is extended into the water, according to the depth of stratified sampling, the four driving motors 4 can be separately controlled to start, so that their output shafts drive the screw rods 5 to rotate. The lifting blocks 6 threadedly connected thereto can drive the sample collection assembly 9 to move vertically downward under the connection and guidance of the connecting rods 7 and the guiding through grooves 8. By controlling the number of turns of the output shafts of the driving motors 4, the depths of multiple sample collection assemblies 9 extending into the water can be adjusted. During collection, the electric push rod 95 is controlled to start, and its telescopic end extends outward, so that the sealing sleeve 96 is disengaged from the feed pipe 93, and water can enter the collection box 91 from the feed pipe 93. After collection, the electric push rod 95 drives the sealing sleeve 96 to return to its original position. After collection, the equipment is taken out of the water, supported by the legs 11, the height of the collection box 91 is adjusted, the valve 97 on the discharge pipe 94 is opened, and it is collected and packaged using a container.
