DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] like Figure 1-6As shown, an embodiment of the present invention provides a sampling device for marine mobile soft soil, including: a square fixed frame 1, a hydraulic cylinder 4 and a sampling tube 5. The hydraulic cylinder 4 is fixedly connected to both sides of the interior of the square fixed frame 1. The hydraulic cylinder 4 is hydraulically extended to lower the connecting frame 26. After lowering, the connecting plate 23 can be pressed down. After pressing down, the sampling tube 5 can be lowered. When the sampling tube 5 is lowered, due to the conflict between the driving motor 8 structure and the soft soil, the fixing ring 14 will slide up on the surface of the sliding rod 7. After the sampling is completed, the hydraulic cylinder 4 is recovered, and the sampling tube 5 rises. The extended end of the hydraulic cylinder 4 is fixedly connected to the connecting frame 26. The connecting frame 26 is in the shape of an L-shaped curved tube. The sampling tube 5 can be recovered inside the square fixed frame 1 through the structure of the L-shaped curved tube. One end of the connecting frame 26 is fixedly connected to a connecting plate 23, and the sampling tube 5 is fixedly connected between the connecting plates 23. An internal thread groove 24 is provided at the top of the sampling tube 5. The internal thread of the internal thread groove 24 is connected to a disassembly stud 25. The structure of the disassembly stud 25 can facilitate the extraction of the soft soil after sampling. The internal of the disassembly stud 25 is fixedly connected to a filter screen 27. The filter screen 27 can prevent the discharge of the soft soil. There is a water source inside the sampling tube 5, and the soft soil enters the interior of the sampling tube 5. When the water is discharged from the seawater through the filter screen 27, the soft soil is retained. The bottom end of the connecting plate 23 is fixedly connected to the slide bar 7, and the bottom end of the slide bar 7 is fixedly connected to the pointed cone block 22. One side of the inner bottom end of the sampling tube 5 is fixedly connected to the first fixed triangular inclined block 6, and the other side of the inner bottom end of the sampling tube 5 is fixedly connected to the second fixed triangular inclined block 9. A rotating shaft is arranged above the second fixed triangular inclined block 9, and the rotating shaft is fixedly connected to the inner wall of the sampling tube 5. The outer rotation of the rotating shaft is connected to the flip plate 11, which is resisted by the gravity, and the flip plate 11 can be pressed by the tension spring 10 and the volute spring 12. 1 resets the friction with the first fixed triangular inclined block 6, retains the sampled soft soil inside the sampling tube 5, lowers the first fixed triangular inclined block 6 and the second fixed triangular inclined block 9 and inserts them into the flowing soft soil. When the soil enters the sampling tube 5, the soil can be smoothly stored inside the sampling tube 5 due to the flip structure of the flip plate 11. A volute spring 12 is arranged inside the rotating shaft. A bellows 13 is fixedly connected between the flip plate 11 and the second fixed triangular inclined block 9. The bellows 13 prevents the water source from eroding the tension spring 10. The tension spring 10 is fixedly connected inside the bellows 13 to provide a reset effect.

[0031] The outer sliding fit of the slide bar 7 has two fixing rings 14, one side of the fixing ring 14 is fixedly connected to a driving motor 8. After the square pointed cone 16 supports the square fixed frame 1, the driving motor 8 is at the bottom end of the slide bar 7 due to gravity, and the outer side of the driving motor 8 is fixedly connected to an electric telescopic rod 15. Through the action of the electric telescopic rod 15, electric telescopic control can be achieved, which is convenient for the contact of the middle arc groove of the driving shaft 19 to reach the limit. The electric telescopic rod 15 extends, and the driving shaft 19 continues to rotate. When the arc groove and the extended end of the electric telescopic rod 15 contact, the limit locking effect is achieved, which can The fixed structure that can keep the scraper 21 is not easy to affect the descent of the sampling tube 5. The extended end of the electric telescopic rod 15 and the arc-shaped mouth are in conflict with each other. The driving end of the driving motor 8 is fixedly connected with the driving shaft 19, and the bottom end of the driving shaft 19 is fixedly connected with the scraper 21. After the driving motor 8 drives, the rotation of the driving shaft 19 will drive the scraper 21 to rotate. During the rotation, the floating soil, impurities and silt at the bottom of the ocean can be cleaned. The middle part of the driving shaft 19 is fixedly connected with a limiting plate 20, and an arc-shaped mouth is opened on one side of the limiting plate 20. The middle part of the top of the square fixed frame 1 is fixedly connected with the connecting shaft 1 8. The external rotation of the connecting shaft 18 is matched with the steel wire rope connecting pipe 3. The steel wire rope is connected through the steel wire rope connecting pipe 3. At the same time, the short-circuit linearity required for power supply is also connected to the equipment in the square fixed frame 1 through the steel wire rope connecting pipe 3. After the power supply operation is completed, the steel wire rope connecting pipe 3 is connected to the connecting shaft 18, and the square fixed frame 1 in the sampling equipment can be placed in the ocean. The top two ends of the square fixed frame 1 are fixedly connected with counterweight blocks 2. The counterweight blocks 2 are used to increase the counterweight and sink quickly. The bottom end of the square fixed frame 1 is fixedly connected with a square pointed cone 16 Through the action of the counterweight 2, the square fixed frame 1 can be quickly sunk to the bottom of the sea, and can be inserted into the soft sand through the square pointed cone 16 to increase the firmness. A camera 17 is fixedly connected to the middle of one side of the square fixed frame 1. The camera 17 structure can be used to check whether the descent depth has touched the bottom. A number of drainage holes 28 are opened in the middle of the top of the square fixed frame 1. When the square fixed frame 1 sinks to the bottom of the sea, the drainage holes 28 can discharge water upward. It should be noted that the above-mentioned hydraulic cylinder 4, drive motor 8, electric telescopic rod 15 and camera 17 must all have a waterproof effect.

[0032] Working principle: when in use, first connect the steel wire rope connecting pipe 3 to the connecting shaft 18, so that the square fixed frame 1 in the sampling equipment can be placed in the ocean, and then the counterweight 2 can quickly sink the square fixed frame 1 to the seabed, and the square pointed cone 16 can be inserted into the soft sand to increase firmness. When the square fixed frame 1 sinks to the seabed, the drainage hole 28 can discharge the water source upward, and then the square pointed cone 16 supports the square fixed frame 1. The driving motor 8 is at the bottom of the slide bar 7 due to gravity. After the driving motor 8 drives the rear driving shaft 19 to rotate, the scraper 21 will be driven to rotate. During the rotation, the floating soil, impurities and silt at the bottom of the ocean can be cleaned. After the cleaning is completed, the electric telescopic rod 15 extends, and the driving shaft 19 continues to rotate. When the arc groove and the extended end of the electric telescopic rod 15 collide, a limit locking effect is achieved, which can keep the fixed structure of the scraper 21 not easy to affect the descent of the sampling tube 5. At this time, the hydraulic cylinder 4 is hydraulically extended to lower the connecting frame 26. After the lowering, the connecting plate 23 can be pressed down. After the pressing down, the sampling tube 5 can be lowered, and the first fixed triangular inclined block 6 and the second fixed triangular inclined block 9 can be lowered and inserted into the flowing soft soil. When the soil enters the interior of the sampling tube 5, the soil can be smoothly stored in the interior of the sampling tube 5 due to the flipping structure of the flip plate 11. Since there is a water source inside the sampling tube 5, when the soft soil enters the interior of the sampling tube 5, the seawater will be discharged through the filter screen 27 to retain the existence of the soft soil. When the sampling tube 5 is descending, due to the conflict between the driving motor 8 structure and the soft soil, the fixed ring 14 will slide and rise on the surface of the slide bar 7. After the sampling is completed, the hydraulic cylinder 4 is recovered, and the rise of the sampling tube 5 will conflict with the flip plate 11 through the action of gravity, and through the action of the tension spring 10 and the volute spring 12, the flip plate 11 can be reset to conflict with the first fixed triangular inclined block 6, so that the soft soil after sampling is retained in the interior of the sampling tube 5.
