Description

Technical Field

[0001] The invention relates to the technical field of sampling, in particular to a protective sampling device for marine engineering. Background Art

[0002] In the geological exploration of marine engineering, it is necessary to sample the mud on the seabed on site. The existing methods for sampling mud mainly include gravity type and excavation type. The sampling volume is large each time, which is suitable for sampling soft mud on the seabed at a large depth. When it is necessary to sample the harder mud bed on the shallow surface, gravity tools are used to sample the shallow mud bed. Since the shallow mud bed is shallow, the gravity tool cannot fully dive, so it is impossible to quickly sample the shallow mud bed. At this time, the sampler dives directly to the shallow mud bed and directly shovels the shallow mud bed by carrying tools such as a bucket. Since the surface of the shallow mud bed is hard, the sampler needs to use a bucket to knock on the surface of the shallow mud bed before collecting it. After the sampler knocks on the surface of the shallow mud bed with a bucket, the mud bed will surge, thereby affecting the sampler's line of sight on the seabed, and then affecting the sampler's sampling speed of the mud in the shallow mud bed.

[0030] Working principle:

[0031] When in use: the first step is to hold the side handle 14 to drive the sampling console 10 to dive to the surface of the shallow mud bed on the seabed. After placing the four screws 21 on the hard surface of the shallow mud bed, the sampling console 10 drives the four screws 21 to press downward to make close contact with the surface of the shallow mud bed. Hold the recursive rotation handle 26 to drive the ring sleeve 24 and make the rotating sleeve teeth 23 rotate outside the limit ring 25. The rotation of the rotating sleeve teeth 23 drives the four gear discs 22 to rotate synchronously. The four gear discs 22 drive the four screws 21 and screw into the interior of the shallow mud bed to fix the sampling console 10. At this time, the turntable 12 is rotated to drive the vertical stud 11 to spiral downward outside the sampling console 10. The vertical stud 11 drives the sampling insert 17 and the sampling ring knife 18 to squeeze, crush and cut into the hard surface of the shallow mud bed, thereby embedding the mud inside the shallow mud bed into the interior of the sampling insert 17 for collection.

[0032] In the second step, after collecting the mud and sand by embedding them into the sampling insert 17, the overall direction of the sampling console 10 and the sampling insert 17 is turned over, so that the sampling insert 17 and the sampling ring knife 18 drive the mud and sand to be placed upward, and the two abutment plates 54 are moved toward each other and contracted inside the pull plate 52, and the pull plate 52 is pulled to make it separate from the inside of the second fixed seat 51. At this time, the baffle 31 is slid on the outside of the sampling insert 17 in the direction away from the sampling console 10, and at the same time, the two sealing plates 30 in the protective components on both sides are rotated toward each other on the outside of the two baffles 31, and the two sealing plates 30 seal the outside of the sampling insert 17 and the sampling ring knife 18, so as to seal the mud and sand inside the sampling insert 17, so as to prevent the mud and sand from scattering outward and blocking the line of sight of the sampler when the sampler carries the mud and sand upward.

[0033] The third step is to rotate the sealing plates 30 in the two protective components together, and then drive the turntable 42 to rotate the plug plate 44 so that the two ends of the plug plate 44 are respectively engaged in the empty groove 41 and the slot 45. The plug plate 44 fixes the fitting parts of the two sealing plates 30 to prevent the sealing plates 30 from flipping outward and causing the mud and sand inside the sampling tube 17 and the sampling ring knife 18 to leak outward.

[0034] The fourth step is to take out the sediment after sampling, and when the sediment needs to be removed, grab the gripping plate 61 and pull it away from the sampling insert 17. The gripping plate 61 drives the partition 60 and causes the interference fit column 65 to disengage from the inside of the embedded groove 64, and the partition 60 is pulled outward from the through groove 62, so that the sediment inside the sampling insert 17 is exposed to the outside, thereby facilitating the sampling personnel to take out the sediment stored in the sampling insert 17.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
