[0028] The present utility model provides a technical solution:

[0029] Embodiment 1

[0030] Combined with Figures 1 to 5 , a portable benthic animal sampler, including a sampling box 3, sieve plates 31 are fixedly connected inside the left and right sides of the sampling box 3, a closing mechanism 1 is arranged inside the top of the sampling box 3, and an entering mechanism 2 is arranged at the bottoms of the front and rear sides of the sampling box 3.

[0031] The closing mechanism 1 includes a closing component 11, a telescopic component 12, an adjusting component 13 and a limiting component 14. The closing component 11 is arranged inside the top of the sampling box 3, the telescopic component 12 is arranged inside the closing component 11, the adjusting component 13 is arranged at the top of the telescopic component 12, and the limiting component 14 is arranged at the four corners of the bottom of the closing component 11.

[0032] The closing component 11 includes a top cover 1101, which is snap-fitted into the top of the sampling box 3, and a handle 1102 is fixedly connected to the top of the top cover 1101.

The adjusting component 13 includes a torsion plate 1301, and the torsion plate 1301 is fixedly connected to the threaded shaft. At the top of 1202, the outer ring of the torsion plate 1301 is rotatably connected to the sleeve 1302, and the sleeve 1302 is fixedly connected to the top of the top cover 1101. The limiting assembly 14 includes a convex plate 1401, and the convex plate 1401 is fixedly connected to the four inner corners of the bottom of the top cover 1101. The bottom of the convex plate 1401 is fixedly connected to a telescopic rod 1402, and the bottom of the telescopic rod 1402 is fixedly connected to a slider 1403. The outer ring of the slider 1403 is slidably connected to a telescopic tube 1404, and the telescopic tube 1404 is fixedly connected to the front and rear sides of the sampling box 3, and the telescopic tube 1404 is slidably connected to the outer ring of the telescopic rod 1402.

[0033] Furthermore: the staff only needs to rotate the torsion plate 1301 to drive the threaded shaft 1202 to rotate to complete the lifting and lowering of the top cover 1101, so that the staff can quickly complete the closing or opening and closing of the top cover 1101 and the sampling box 3, which is convenient for the staff to replace the bait in the sampling box 3 or take out the captured animals. The operation is simple and convenient for the staff to use. At the same time, the setting of the four-corner telescopic rod 1402 and the telescopic cylinder 1404 limits the top cover 1101, so that the position of the top cover 1101 cannot be deflected during the lifting process, so that the top cover 1101 can always remain aligned with the sampling box 3, increasing the stability of the structure, and the setting of the slider 1403 limits the upward distance of the top cover 1101, so that the threaded shaft 1202 cannot be separated from the connection with the fixed screw cylinder 1203 during the upward process.

[0034] Embodiment 2

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 On the basis of Example 1, it is further obtained that the entry mechanism 2 includes an entry component 21, a flip component 22 and an anti-escape component 23, the entry component 21 is arranged at the bottom of the front and rear sides of the sampling box 3, the flip component 22 is arranged in the entry component 21, and the anti-escape component 23 is arranged above the flip component 22.

[0036] The inlet component 21 includes a trapping port 2101, the trapping port 2101 is fixedly connected to the bottoms of the front and rear sides of the sampling box 3, fixed shafts 2102 are fixedly connected to the left and right sides inside the trapping port 2101, the flipping component 22 includes a rotating cylinder 2201, the rotating cylinder 2201 is rotatably connected to the outer circle of the fixed shaft 2102, a flipping net plate 2202 is fixedly connected to the bottom of the rotating cylinder 2201, the outer side of the flipping net plate 2202 is attached to the inner side of the trapping port 2101, the anti-escape component 23 includes a tab 2301, the tab 2301 is fixedly connected to the top of the rotating cylinder 2201, the outer side of the tab 2301 is attached to the inner top of the trapping port 2101, and a limiting block 2302 is arranged inside the tab 2301, the limiting block 2302 is fixedly connected to the inner top of the trapping port 2101.

[0037] Furthermore: Benthic organisms in the river enter the sampling box 3 through the trapping port 2101, and the limiting block 2302 limits the flipping direction of the flipping net plate 2202 through the tab 2301, so that the flipping net plate 2202 can only flip inward and cannot flip outward, preventing the benthic organisms that have entered the sampling box 3 from leaving through the trapping port 2101 again. In addition, a reset device, such as a reset spring, can be arranged on the rotating cylinder 2201 and the fixed shaft 2102 to prevent the flipping net plate 2202 from being opened by the water flow; this device can be placed in the river and complete the sampling of benthic organisms by itself without the assistance of staff, improving the efficiency of capturing and sampling benthic organisms when using this device.

[0038] During the actual operation process, when using this device, the staff first rotates the torsion disk 1301. The rotation of the torsion disk 1301 drives the threaded rotating shaft 1202 to rotate. The threaded rotating shaft 1202 rotates and moves upward inside the fixed screw cylinder 1203. The upward movement of the threaded rotating shaft 1202 drives the top cover 1101 to move upward through the fixed collar 1201. After that, the staff places the trapping bait in the sampling box 3, and then rotates the torsion disk 1301 in the reverse direction to drive the top cover 1101 downward. The downward movement of the top cover 1101 is clamped inside the top of the sampling box 3 to complete the closing of the sampling box 3.

[0039] After that, the staff places the sampling box 3 at the bottom of the river. Then, the water flow in the river passes through the sieve plate 31 and the flipping net plate 2202 and exchanges inside and outside the sampling box 3, spreading the smell of the bait in the sampling box 3 to the riverbed to attract benthic organisms to approach the sampling box 3. The benthic organisms that reach near the sampling box 3 are trapped by the bait and enter the sampling box 3 after squeezing the flipping net plate 2202 to flip inward through the trapping port 2101. At this time, the capture of benthic organisms is completed, and the sampling process of benthic organisms is completed.
