Description

Technical Field

[0001] This utility model relates to the field of sediment sampling devices, specifically to a sediment sampling device for monitoring the living environment of shrimp. Background Technology

[0002] Many shrimp species live in mud and sand. To maintain a favorable environment for shrimp growth, it is necessary to use mud and sand sampling devices to collect samples and monitor their living environment. For example, patent application number 201721639398.9 discloses a mud and sand sampling device, including a sampling rod and a pull rod fixedly connected to the sampling rod in the vertical direction. The sampling rod and the pull rod are internally connected, and the bottom end of the sampling rod is not equipped with a bottom plate. A rubber plunger is provided inside the pull rod, and the rubber plunger is slidably matched with the inner wall of the pull rod. Several symmetrically distributed drainage holes are also provided on the inner wall of the pull rod. It has the following advantages: based on the existing borehole exploration of the seabed or riverbed, this device can be used to increase the number of exploration points and compare the results with the soil samples from the borehole points to obtain more accurate geological information.

[0003] However, the patent still has the following drawbacks: because there is no component to cover the drainage hole, the mud and sand sample inside the pull rod is prone to leaking out of the drainage hole after the sampling is completed, which is inconvenient to use. Utility Model Content

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sampling tube 1 has a hollow structure. The adjusting plate 8 is located on the side of the drainage hole 13. The adjusting plate 8 can cover the drainage hole, so that the mud and sand sample in the sampling tube 1 is not easily leaked out of the drainage hole after sampling. The guide plate 3 is fixedly installed on the side of the sampling tube 1. The fixing plate 4 and the positioning block 10 are fixedly installed above the guide plate 3. The first screw 5 and the first optical rod 6 are fixedly connected between the fixing plate 4 and the sampling tube 1. The first screw sleeve 7 is screwed to the outside of the first screw 5 and abuts against the side of the adjusting plate 8. The adjusting plate 8 is in sliding contact with the first optical rod 6. The side of the adjusting plate 8 is provided with a first sliding through hole corresponding to the first optical rod 6. The first optical rod 6 passes through the first sliding through hole.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjusting plate 8 is slidably mounted on the side of the guide plate 3. The side of the guide plate 3 has a sliding opening that matches the adjusting plate 8, facilitating the sliding of the adjusting plate 8. The adjusting plate 8 passes through the sliding opening. The limiting strip 9 is mounted on the side of the adjusting plate 8 via a pin. The side of the fixing plate 4 has a handle slot located above the first screw 5. The cover plate 11 is located above the sampling tube 1. The side of the sampling tube 1 has a first opening corresponding to the blocking plate 12, facilitating the passage of the blocking plate 12. The blocking plate 12 passes through the first opening.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the movable wheel 17 is fixedly installed below the auxiliary plate 16, and the bottom end of the movable wheel 17 is located below the bottom end of the sampling tube 1. The fixing frame 19 is fixedly installed at the end of the auxiliary plate 16. The fixing frame 19 is located on the front and rear sides of the mounting block 14. The second screw 20 and the second smooth rod 21 are fixedly installed inside the fixing frame 19. The second screw sleeve 22 is screwed onto the outside of the second screw 20. The second screw sleeve 22 abuts against the side of the movable plate 23. The movable plate 23 is in sliding contact with the second smooth rod 21. The side of the movable plate 23 is provided with a second sliding through hole corresponding to the second smooth rod 21, which facilitates the sliding of the movable plate 23. The second smooth rod 21 passes through the second sliding through hole. The spring 24 is connected between the movable plate 23 and the fixing frame 19. The connecting block 25 is fixedly connected to the side of the movable plate 23. The side of the fixing frame 19 is provided with a second opening corresponding to the connecting block 25, which facilitates the passage of the connecting block 25.

The end of the connecting block 25 passes through the second opening and is inserted into the slot.

[0022] Example: The addition 15 allows for easy movement of the product by gripping the handle slot of the fixing plate 4, facilitating its carrying. Before sampling, first rotate the second threaded sleeve 22 of the connecting mechanism 18. The second threaded sleeve 22 will move away from the mounting block 14, at which point the spring 24 will gradually return from its stretched state, driving the movable plate 23 away from the mounting block 14. This allows the end of the connecting block 25 to move out of the slot in the mounting block 14, making it easy to remove the addition 15. Then, rotate the first threaded sleeve 7 of the adjusting mechanism 2. The first threaded sleeve 7 will move away from the sampling tube 1. Next, move the adjusting plate 8, open the cover plate 11 and the blocking plate 12, and then rotate the limiting strip 9 to adjust it from a vertical state to a horizontal state (e.g., ...). Figure 5 As shown, the cover plate 11 and the blocking plate 12 can be kept open. Then, the sampling tube 1 is inserted into the mud and sand. The water and some mud and sand in the mud and sand will be discharged through the drain hole 13. After stabilizing for a period of time, the limiting strip 9 is rotated to adjust the limiting strip 9 from a horizontal state to a vertical state. Then, the first screw sleeve 7 is rotated in the opposite direction to push the adjusting plate 8 close to the sampling tube 1. The cover plate 11 and the blocking plate 12 can seal the upper and lower ends of the sampling tube 1. The adjusting plate 8 can cover the drain hole 13, so that after sampling, the mud and sand sample in the sampling tube 1 is not easy to leak out from the drain hole 13.
