[0025] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively exclusive of other embodiments.

[0028] Refer to Figures 1 to 6 , which is the first embodiment of the present invention. This embodiment provides a karst cave structure survey device, including an exploration unit 1, which includes a connector 11, an outer tube 12 provided at the bottom end of the connector 11, a limit assembly 13 provided in the inner cavity of the connector 11, an inner tube 14 provided on the limit assembly 13, and a drill bit 15 provided at the bottom ends of the outer tube 12 and the inner tube 14;

[0029] A driving unit 2, which is provided at the top end of the connector 11 and is detachably connected to the connector 11;

[0030] A water outlet pipe 151 is provided in the inner cavity of the drill bit 15.

[0031] It should be noted that the output end of the driving unit 2 is threadedly connected with a connector 11. The driving unit 2 is a portable driving motor. A coolant is also connected to the driving unit 2. The coolant is injected into the connector 11 through the output end. The bottom of the connector 11 is fixedly connected with an outer tube 12 by bolts. A limiting component 13 is fixedly connected inside the connector 11. An inner tube 14 is arranged at the limiting end of the limiting component 13. The bottom end of the outer tube 12 is threadedly connected with a drill bit 15. The inner diameter of the drill bit 15 is less than or equal to the radius of the inner tube 14. A sealing cavity is formed between the inner tube 14 and the outer tube 12. The coolant is injected into the sealing cavity from the connector 11 and flows out from a water outlet pipe 151 opened in the inner cavity of the drill bit 15.

[0032] During use, after the inner tube 14 is limited and fixed by the limiting component 13, the outer tube 12 is sleeved on the inner tube 14 and tightened on the connector 11 by bolts. Then the drill bit 15 is tightened at the bottom end of the outer tube 12. Finally, after the connector 11 is connected to the output end of the driving motor, the driving motor is held by hand and drilled into the area in the karst cave that needs to be sampled for sampling.

[0033] After sampling, the drill bit 15 is removed, then the bolts are loosened, the outer tube 12 is removed, and finally the limiting component 13 is opened to remove the inner tube 14, realizing the sampling of the karst cave structure. By taking out the samples in the inner tube 14, the analysis and survey of the karst cave structure are realized.

[0034] In summary, by miniaturizing the conventional large coring equipment and changing the driving equipment to a relatively common handheld driving equipment in this field, it can be more convenient to carry. After the structure is miniaturized, it can be more convenient to sample at multiple positions according to the internal situation of the karst cave, avoiding the situation where the conventional coring equipment can only perform vertical coring.

[0035] As Figure 2 shown, as an optional embodiment: the outer tube 12 includes an extension tube 121 arranged at the bottom end of the connector 11, an expansion tube 122 threadedly arranged at the bottom end of the extension tube 121, and a connecting tube 123 threadedly arranged at the bottom end of the expansion tube 122.

[0036] The connecting tube 123 is threadedly connected with the drill bit 15.

[0037] It should be noted that the extension tube 121 is hermetically connected to the bottom end of the connector 11 by bolts. The expansion tube 122 is threadedly connected to the bottom of the extension tube 121, and the connecting tube 123 is threadedly connected to the bottom end of the expansion tube 122. By replacing the extension tube 121 with different lengths, coring at different depths can be satisfied. The expansion tube 122 can expand the radius of the drilling hole and expand the flow channel of the mud. The drill bit 15 is threadedly connected to the bottom end of the connecting tube 123.

[0038] As Figures 2 to 5As shown, as an alternative embodiment: the inner tube 14 includes a plug 141 disposed within the limit assembly 13, a core tube 142 threadedly disposed at the bottom end of the plug 141, and a leak prevention assembly 143 disposed at the bottom end of the core tube 142;

[0039] The plug 141 includes a plug body 1411, a limit groove 1412 opened at the top end of the plug body 1411, and a through hole 1413 opened on the outer wall of the plug body 1411;

[0040] The core tube 142 includes an arc-shaped plate 1421, a card slot 1422 opened on the outer wall of the arc-shaped plate 1421, and a buckle 1423 disposed within the card slot 1422.

[0041] It should be noted that the two arc-shaped plates 1421 are provided with card slots 1422, and buckles 1423 are clamped on the card slots 1422. After the two arc-shaped plates 1421 are spliced, their two ends are respectively threadedly connected to the plug body 1411 and the leak prevention assembly 143 to complete the fixation of the two arc-shaped plates 1421 and form the core tube 142.

[0042] During use, through the continuous drilling of the drill bit 15, the structure in the karst cave enters the core tube 142 after passing through the leak prevention assembly 143. During the rotation of the drill bit 15, the coolant in the connector 11 enters between the inner tube 14 and the outer tube 12 through the through hole 1413 and flows out from the water outlet pipe 151 on the drill bit 15, which can not only cool the outer tube 12 and the drill bit 15, but also wash the mud;

[0043] After core sampling, the inner tube 14 is taken out. After unscrewing the plug body 1411 and the leak prevention assembly 143 at both ends of the core tube 142, the buckle is removed, and the arc-shaped plate 1421 is opened to obtain a complete core body, which can prevent the problem that when the inner tube 14 is an integral non-detachable pipeline, the core body is mixed during the extraction process, resulting in inaccurate data.

[0044] As Figure 3 shown, as an alternative embodiment: the leak prevention assembly 143 includes an insertion tube 1431, a sliding groove 1432 disposed within the inner cavity of the insertion tube 1431, a baffle 1433 rotatably disposed within the sliding groove 1432, a pressing plate 1434 slidably disposed within the sliding groove 1432, and a spring 1435 disposed between the pressing plate 1434 and the sliding groove 1432.

[0045] It should be noted that the insertion tube 1431 is threadedly connected to the bottom end of the core tube 142. A plurality of sliding grooves 1432 are opened within the insertion tube 1431. The sliding grooves 1432 are rotatably connected to the baffle 1433 and vertically slidably connected to the pressing plate 1434. The pressing plate 1434 is located above the baffle 1433, and a spring 1435 is disposed between the pressing plate 1434 and the sliding groove 1432.

[0046] When in use, during the process of the sampling core entering the inner tube 14, the extrusion plate 1434 is pushed upward, and the extrusion plate 1434 rotates and contracts into the sliding groove 1432. After the sampling is completed, the core no longer enters the inner tube 14. When the device is lifted, the bottom of the extrusion plate 1434 loses the thrust. Under the action of the spring 1435, the extrusion plate 1434 presses against the baffle 1433, and the baffle 1433 rotates to block the bottom of the inner tube 14, making the taken-out core more complete and accurate.

[0047] As Figures 4 to 6 shown, as an alternative embodiment: The limiting component 13 includes a mounting disk 131 arranged in the inner cavity of the connecting head 11, a driving disk 132 rotatably arranged in the mounting disk 131, a limiting block 133 slidably arranged in the inner cavity of the mounting disk 131, a pushing groove 134 formed on the driving disk 132, a positioning rod 135 arranged on the lower surface of the limiting block 133, and a driving member 136 arranged between the mounting disk 131 and the driving disk 132;

[0048] The driving member 136 includes a worm gear 1361 arranged at the bottom of the driving disk 132, a mounting block 1362 arranged at the bottom of the mounting disk 131, and a worm 1363 rotatably arranged in the mounting block 1362;

[0049] The worm 1363 penetrates through the connecting head 11, and one end of the worm 1363 is fixedly connected with a knob 1363-1.

[0050] It should be noted that the mounting disk 131 is fixedly installed in the inner cavity of the connecting head 11. The bottom inner cavity of the rotating disk 131 is rotatably connected with the driving disk 132. Above the driving disk 132 and on the inner wall of the rotating disk 131, multiple groups of limiting blocks 133 are slidably connected. The bottom of the limiting block 133 is fixedly connected with a positioning rod 135. A pushing groove 134 corresponding to the limiting block 133 is formed on the driving disk 132. The positioning rod 135 is located in the pushing groove 134 and is slidably connected with the inner wall of the pushing groove 134. A worm gear 1361 is fixedly connected to the bottom end of the driving disk 132. A mounting block 1362 is fixedly connected to the bottom of the mounting disk 131. A worm 1363 is rotatably connected to the mounting block 1362. The worm 1363 and the worm gear 1361 are meshed with each other, and one end of the worm 1363 is fixedly connected with a knob 1363-1.

[0051] During use, after the plug body 1411 is inserted into the inner cavity of the mounting disc 131, the limiting groove 1412 reaches the limiting block 133. Rotate the knob 1363-1 to drive the worm 1363 to rotate, and then drive the turbine 1361 to rotate. The turbine 1361 drives the driving disc 132 to rotate. The pushing groove 134 pushes the positioning rod 135 to push the limiting block 133 out of the mounting disc 131 and snap it into the limiting groove 1412. The limiting block 133 only plays a limiting role for the inner tube 14. When the inner tube needs to be removed, rotate the knob 1363-1 in the reverse direction to drive the driving disc 132 to rotate in the reverse direction. The pushing groove 134 pushes the positioning rod 135 to retract the limiting block 133 into the mounting disc 131. The purpose of the limiting block 133 restricting the inner tube 14 is to connect the inner tube 14. The inner tube 14 and the connector 11 are relatively rotationally connected through the limiting block 133. Therefore, when the connector 11 rotates, the inner tube 14 will not rotate along with it under the frictional force of the core body, thereby reducing the problem that the inner tube 14 may rotate along with it, generating amplitude, causing the sampling core body to break, and interfering with the sampling data.

[0052] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
