[0021] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0022] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0023] See also Figure 1-Figure 6 As shown, the present invention is a geotechnical engineering geological drilling exploration and monitoring device, including a plate 1, the plate 1 is fixedly installed with a driving motor 2, the output shaft of the driving motor 2 is fixedly installed with a drill rod 3, the drill rod 3 is slidably connected with a protective shell 4, a micro motor 5 is arranged inside the drill rod 3, the output shaft of the micro motor 5 is fixedly installed with a rotating shaft 6, the rotating shaft 6 is provided with a sampling mechanism, the sampling mechanism includes a double-headed cam 7 arranged on the rotating shaft 6, the raised surface of the double-headed cam 7 is in contact with a sliding block 8, and the end of the sliding block 8 away from the double-headed cam 7 is fixedly installed with a sampling tube 9.

[0024] The working principle of a geotechnical engineering geological drilling exploration and monitoring device proposed in the present invention is to first move the device to a specified position, then start the drive motor 2, and drive the drill rod 3 to rotate through the output shaft of the drive motor 2, so as to drill the rock and soil layer. At this time, the protective shell 4 covers the drilling position, which can avoid the splashing of debris during drilling, and can also effectively prevent dust from spreading outward to avoid polluting the environment. It can also effectively protect the surveyors and facilitate the surveyors to conduct surveys.

[0025] It is worth noting that after completing the above-mentioned drilling, the micro motor 5 is started, and the rotating shaft 6 is driven to rotate through the output shaft of the micro motor 5, thereby driving the double-headed cam 7 to rotate, so that the raised surface of the double-headed cam 7 contacts one end of the sliding block 8, so that the sliding block 8 is resisted by the double-headed cam 7 and moves away from the drill rod 3, thereby driving the sampling tube 9 to move away from the drill rod 3, so that the sampling tube 9 is inserted into the rock and soil layer, and then the rock and soil samples at the drilling site are collected, which facilitates the sampling of rock and soil.

[0026] After completing the above operations, the micro motor 5 is started in reverse, so that the sampling tube 9 is retracted into the inside of the drill rod 3, avoiding that the sampling tube 9 is always in the expanded state when the drill rod 3 moves upward, causing too many rock and soil samples to enter the sampling tube 9 and affect the detection of the samples.

[0027] In one embodiment, for the micro motor 5 , the micro motor 5 is fixedly installed inside the drill rod 3 , the rotating shaft 6 is rotatably installed inside the drill rod 3 , and the sliding block 8 is slidably connected inside the drill rod 3 .

[0028] In one embodiment, for the above-mentioned double-headed cam 7, multiple double-headed cams 7, sliding blocks 8 and sampling tubes 9 are provided, and protruding base blocks 10 are fixedly installed at both ends of the sliding block 8. The protruding base block 10 is slidably connected to the inside of the drill rod 3, and one end of the reset spring 11 is fixedly installed on the protruding base block 10, and the other end of the reset spring 11 is fixedly installed on the inner wall of the drill rod 3.

[0029] The working principle of the geotechnical engineering geological drilling exploration and monitoring device proposed by the present invention is to start the micro motor 5, thereby driving the rotating shaft 6 to rotate, and then driving the double-headed cam 7 to rotate, so that the raised surface of the double-headed cam 7 contacts one end of the sliding block 8, and then the sliding block 8 is resisted by the double-headed cam 7 and moves away from the drill rod 3, thereby driving the sampling tube 9 to move away from the drill rod 3, and then the sampling tube 9 is inserted into the rock and soil layer, so as to collect rock and soil samples at the drilling location.

[0030] After completing the above sampling, the micromotor 5 is started in reverse, thereby driving the double-headed cam 7 to reset. It is worth noting that when the sliding block 8 moves outward, the reset spring 11 undergoes elastic deformation and maintains a certain tension. Therefore, when the raised surface of the double-headed cam 7 is not in contact with the sliding block 8, the reaction force of the reset spring 11 is used to drive the sliding block 8 and the sampling tube 9 to reset, thereby storing the sampling tube 9 into the interior of the drill rod 3.

[0031] In one embodiment, for the above-mentioned plate 1, one end of a rod 12 is fixedly mounted on the plate 1, the other end of the rod 12 is fixedly mounted on a moving plate 13, the top of the moving plate 13 is fixedly mounted with an output shaft of a driving cylinder 14, and the driving cylinder 14 is fixedly mounted on a top plate 15.

[0032] In one embodiment, for the top plate 15, one end of a connecting rod 16 is fixedly mounted on the top plate 15, and the other end of the connecting rod 16 is fixedly mounted on the bottom plate 17. A universal wheel 18 is fixedly mounted on the bottom of the bottom plate 17, and the universal wheel 18 has a self-locking property.

[0033] The working principle of the geotechnical engineering geological drilling survey monitoring device proposed by the present invention is that the device can be moved at will through the universal wheel 18, and after being moved to a suitable position, it can be fixed by using the self-locking property of the universal wheel 18.

[0034] It is worth noting that after moving to the appropriate position, the driving cylinder 14 is started, thereby driving the moving plate 13 and the plate 1 to move. At this time, the driving motor 2 is started again, so that the drill rod 3 can move downward while drilling, thereby improving work efficiency.

[0035] In one embodiment, for the bottom plate 17 , the bottom plate 17 is slidably connected to a first plugging rod 19 , and four first plugging rods 19 are provided to stabilize the bottom plate 17 .

[0036] In one embodiment, for the above-mentioned bottom plate 17, the bottom plate 17 is provided with two insertion holes 20, and the two insertion holes 20 are slidably connected with second insertion rods 21, and the second insertion rods 21 are fixedly installed at the bottom of the plate 1, and the two second insertion rods 21 are used to stabilize the plate 1.

[0037] In one embodiment, for the bottom plate 17 , the bottom plate 17 is provided with a hole 22 , and the drill rod 3 and the protective shell 4 are slidably connected to the hole 22 .

[0038] In one embodiment, for the above-mentioned sampling mechanism, the sampling mechanism is provided with multiple groups, and the parts and installation methods thereof are the same and are evenly distributed inside the drill rod 3 .

[0039] The working principle of the geotechnical engineering geological drilling exploration and monitoring device proposed in the present invention is that the staff fixes the first insertion rod 19 above the rock and soil layer through tools, so as to stabilize the bottom plate 17, and when the plate 1 moves downward, the second insertion rod 21 is synchronously driven to pass through the hole 20 and inserted into the top of the rock and soil layer, so that the plate 1 can be stabilized when the drill rod 3 is drilling.

[0040] It is worth noting that the first plug rod 19 and the second plug rod 21 are used for stabilization, thereby preventing the device from being offset during operation and affecting the survey results.
