Description

Technical Field

[0001] The utility model relates to the technical field of core sampling, in particular to a portable and adjustable core sampling device. Background Art

[0002] In the process of field survey and exploration and oil field research, the core is the first-hand data, the most basic and important, and the important basis for subsequent scientific research. The portable core sampling device needs to be stable for a long time when in use. If it encounters hard rocks, drilling is extremely difficult and it is difficult to maintain stability. It also consumes the physical strength of the staff, thereby affecting the drilling effect. Therefore, the portable core sampling device increases its stable components during drilling. A patent application with publication number CN218895976U discloses a core sampling and exploration device, which is provided with an automatic water injection component and a pump, so that water is injected into the inside of the drilling pipe, and the drilling pipe is sampled and cooled to ensure the strength of the drilling pipe. At the same time, after the sampling is completed, the internal pressure of the drilling pipe can be increased by water injection, and the drilled core sample is pushed out by the action of water pressure, and at the same time, it can offset part of the heat generated by drilling when drilling hard rocks, and ensure the main body strength and drilling effect of the drilling pipe.

[0003] In the above-mentioned prior art, there is no component for increasing the overall stability of the device. If encountering hard rock, drilling is extremely difficult and it is difficult to maintain stability. It will also consume a lot of physical strength of the workers, thus affecting the drilling effect.

[0004] To this end, the utility model provides a portable and adjustable core sampling device. Utility Model Content

[0026] A hand grip frame 9 is fixedly connected above the mounting plate 8 .

[0027] The specific support protection block 1 has two working states when working:

[0028] First working state: when the core sampling device is in use, the upper fixing plate 5 and the lower fixing plate 4 are connected together by rotating the supporting protection block 1 and the fixing block 3, thereby forming a closed space with the mounting plate 8, and the bottom surface of the fixing block 3 is pressed against the rock, which plays a fixed supporting role for the drill bit 10 located in the middle of the fixing block 3, so that the device can be more stable when in use and save the physical strength of the staff;

[0029] Second working state: when the core sampling device is not in use, the supporting protection block 1 and the fixed magnet 6 are rotated inward to fit each other, thereby tightly wrapping the sampling tube 11 and the drill bit 10 to protect the sampling tube 11 and the drill bit 10.
