[0038] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Example 1

[0041] In the prior art, the existing geological exploration slope angle precision measurement device includes a base 1, a column 2 is fixedly mounted on the top surface of the base 1, a crossbeam 3 is fixedly mounted on the side of the column 2, and a drilling mechanism 4 is provided on the bottom surface of the base 1. The drilling mechanism 4 includes a mounting seat 401, a motor 402, and a drill bit 403. The mounting seat 401 is mounted on the bottom surface of the base 1, the motor 402 is mounted inside the mounting seat 401, and the drill bit 403 is connected to the output end of the motor 402. The mounting seat 401 and the base 1 can be fixed by bolts or welded. The bolt fixing method is convenient for disassembly and maintenance, and the welding connection provides higher structural strength and stability. The output end of the motor 402 is connected to the drill bit 403 by a coupling. The coupling can effectively transmit torque and absorb vibration, ensuring the stability of the drill bit 403 during high-speed rotation. This slope angle measuring device also features a drilling mechanism 4 for drilling holes in the ground and a vertical fixing mechanism for inserting a post into the hole, located below a crossbeam 3 near each end. The chassis and crossbeam 3 are slidably connected to adjust their relative position. The sliding connection can utilize either a guide rail or a chute structure. Guide rails provide more precise positioning and stable sliding, while chute structures simplify design and reduce costs. The vertical fixing mechanism and drilling mechanism 4 work together to maintain the entire device in a completely vertical position on the slope and suspend it. The measuring rope naturally droops to contact the ground at the height of a straight section of the measurement area, allowing for precise measurement of the slope of each straight section and the finer slopes of each subsection of the measurement area.

[0042] This application combines the above-mentioned prior art, such as Figures 1-9 As shown, the present invention provides a technical solution: a device for accurately measuring the slope angle in geological exploration, wherein a support mechanism 6 is provided on the bottom surface of the base 1, and a fixing mechanism 5 is provided on the surface of the crossbeam 3. The fixing mechanism 5 includes a ground-inserting column 501, a center pull rod 502 extending through the interior of the ground-inserting column 501, an expansion head 503 hingedly connected to the bottom end of the center pull rod 502, a limiting groove 504 provided on the top surface of the ground-inserting column 501, a clamping block 505 installed on the bottom surface of the ground-inserting column 501, a rotating block 506 fixedly installed on the top end of the center pull rod 502, and a limiting rod 507 fixedly installed on the bottom surface of the rotating block 506, a cylinder 7 installed on the top of the column 2, a cross plate 8 installed on the output end of the cylinder 7, and a measuring mechanism 9 provided on the side of the cross plate 8. The cylinder 7 and the cross plate 8 are fixed by flange connection or bolts. The flange connection provides higher structural strength and stability, while the bolt fixation facilitates disassembly and maintenance.

[0043] In this embodiment, the motor 402 drives the drill bit 403 to rotate through the drilling mechanism 4, and the drill bit 403 drills a hole in the ground. The ground column 501 is then inserted into the drilled hole. By rotating the rotating block 506, the rotating block 506 drives the center pull rod 502 to rotate inside the ground column 501. At the same time, the center pull rod 502 drives the expansion head 503 to expand, thereby further fixing the ground column 501 underground, thereby improving the stability of the device and avoiding affecting the measurement results. The fixation between the ground column 501 and the ground can be achieved by expansion bolts or chemical anchor bolts. Expansion bolts provide fast and reliable fixation, while chemical anchor bolts are suitable for more complex geological conditions.

[0044] Combining the above solutions:

[0045] Going further:

[0046] like Figures 4 and 5 As shown;

[0047] To secure the ground-inserted post 501 underground, in an optional embodiment, the expansion head 503 is composed of three sets of metal plates 508 in the shape of a right-angled trapezoid. The metal plates 508 can be made of high-strength stainless steel or carbon steel. Stainless steel has excellent corrosion resistance, while carbon steel provides greater strength and wear resistance.

[0048] In this embodiment: by controlling the opening and closing of the expansion head 503, it is convenient to reinforce the ground-inserted column 501 underground. At the same time, the shape of the three groups of metal sheets 508 is set to a right-angled trapezoid. When contracted, the inclined surface can push the soil outward, reducing the resistance of the soil to the metal sheets 508, thereby improving the layout efficiency. At the same time, the right-angled trapezoidal shape of the metal sheets 508 can improve the stability of the ground-inserted column 501.

[0049] Combining the above solutions:

[0050] Going further:

[0051] like Figures 3 to 5 As shown;

[0052] To enable the central pull rod 502 to drive the metal sheet 508 to open and close, in one optional embodiment, there are three sets of locking blocks 505, which are arranged in a circular array on the bottom surface of the ground post 501. The three sets of metal sheets 508 are respectively engaged with the three sets of locking blocks 505. The engagement between the locking blocks 505 and the metal sheets 508 can be achieved by springs or elastic pins. The springs provide continuous compression, while the elastic pins simplify the structure and improve reliability.

[0053] In this embodiment: by clamping the clamping block 505 and the metal sheet 508, on the one hand, the opening and closing angle of the metal sheet 508 can be limited to prevent the metal sheet 508 from being damaged by opening at too large an angle; on the other hand, it is convenient to drive the opening and closing of the metal sheet 508 by rotating the central pull rod 502, thereby facilitating the reinforcement of the ground column 501.

[0054] Combining the above solutions:

[0055] Going further:

[0056] like Figures 4 and 5 As shown;

[0057] In order to open and retract the metal sheet 508, in an optional embodiment, the top end of the central pull rod 502 and the top end of the ground post 501 are threaded. The threaded connection can be a fine thread or a coarse thread. The fine thread provides higher connection accuracy, while the coarse thread facilitates quick installation and removal.

[0058] In this embodiment: by rotating the center pull rod 502, the thread at the top of the center pull rod 502 engages with the thread at the top of the ground column 501. At this time, the center pull rod 502 can be displaced a short distance inside the ground column 501. When the limit rod 507 moves to the maximum distance in the limit groove 504, it stops rotating. Since the top of the center pull rod 502 and the top of the ground column 501 are threadedly connected, the thread can lock the center pull rod 502, and the metal sheet 508 is also fixed at this angle.

[0059] Combining the above solutions:

[0060] Going further:

[0061] like Figure 2 As shown;

[0062] To limit the position of the central pull rod 502, in an optional embodiment, a limiting rod 507 is located within the limiting groove 504, and a sliding connection is formed between the limiting rod 507 and the limiting groove 504. The limiting groove 504 can adopt a linear guide or a ball guide. The linear guide provides higher rigidity and precision, while the ball guide reduces friction and improves sliding efficiency.

[0063] In this embodiment: the center pull rod 502 is limited by the limiting rod 507 and the limiting groove 504. When the limiting rod 507 moves from one end of the limiting groove 504 to the other end, the metal sheet 508 rotates to open or close, and the center pull rod 502 is limited by the limiting rod 507 and cannot continue to rotate inside the ground column 501. At this time, the center pull rod 502 can be locked.

[0064] Combining the above solutions:

[0065] Going further:

[0066] like Figure 3 As shown;

[0067] To facilitate the release of the ground post 501, in an optional embodiment, a fixing block 10 is fixedly mounted on the bottom surface of the crossbeam 3. A thumb bolt 11 is inserted into the fixing block 10, securing the ground post 501 to the crossbeam 3. The thumb bolt 11 can be made of stainless steel or galvanized steel. Stainless steel offers excellent corrosion resistance, while galvanized steel offers greater strength and wear resistance.

[0068] In this embodiment: the ground column 501 and the beam 3 are fixed by the fixing block 10 and the hand-tightening bolt 11. It is only necessary to rotate the hand-tightening bolt 11 and remove it from the surface of the ground column 501, and then the ground column 501 can be inserted into the hole opened by the drill bit 403, thereby improving the layout efficiency and speeding up the release of the ground column 501.

[0069] Combining the above solutions:

[0070] Going further:

[0071] like Figures 6 to 8 As shown;

[0072] To directly measure and display the ground's slope angle, in an optional embodiment, measuring mechanism 9 includes a long rod 901 and a measuring disc 902. The ends of long rod 901 are fixed to the inner wall of cross plate 8. There are several sets of measuring discs 902, each movably mounted on the surface of long rod 901. A pendulum 903 is rotatably connected to the interior of each measuring disc 902, and graduated grooves 904 are defined on both sides of each measuring disc 902. The fastening between long rod 901 and cross plate 8 can be achieved by welding or bolting. Welding provides greater structural strength, while bolting facilitates disassembly and maintenance.

[0073] In this embodiment, the slope angle can be directly displayed through the linkage design of the pendulum 903, the measuring disk 902 and the indicator disk 905. This is not only simple and intuitive to operate, but also applicable to different terrains and environments, thereby improving the accuracy of the measurement data and being suitable for quickly measuring the slope angle in geological exploration.

[0074] Combining the above solutions:

[0075] Going further:

[0076] like Figures 6 to 8 As shown;

[0077] To improve measurement accuracy, in an optional embodiment, indicator discs 905 are fixedly mounted on both sides of pendulum 903. Indicator discs 905 extend through both sides of measuring disc 902 and are pivotally connected to measuring disc 902. Pendulum 903 can be made of stainless steel or aluminum alloy. Stainless steel offers excellent corrosion resistance, while aluminum alloy offers the advantages of lightweight and high strength.

[0078] In this embodiment, the center of gravity of the pendulum 903 is located at the bottom, and it can sensitively respond to changes in the slope of the ground. When the slope of the ground changes, the pendulum 903 promptly drives the indicator disk 905 to rotate inside the measuring disk 902. The measurement data can be quickly obtained through the corresponding scale groove 904 of the indicator disk 905.

[0079] Combining the above solutions:

[0080] Going further:

[0081] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 9 As shown;

[0082] To maintain the base 1 in an upright position, in an optional embodiment, the support mechanism 6 includes a support column 601, a fixed column 602, and an extension column 603. The support column 601 is fixedly mounted on the bottom surface of the base 1, the fixed column 602 is rotatably mounted inside the support column 601, and the extension column 603 is inserted inside the fixed column 602. The support column 601 and the base 1 can be fixed by welding or bolting. Welding provides higher structural strength, while bolting facilitates disassembly and maintenance.

[0083] In this embodiment: through the support column 601, the fixed column 602 and the extension column 603, the height of the base 1 can be flexibly adjusted without the help of a power device, making the adjustment range more precise and ensuring that the base 1 and the entire device are always fixed in a vertical state.

[0084] Combining the above solutions:

[0085] Going further:

[0086] like Figure 9 As shown;

[0087] To further enhance the stability of the device, in an optional embodiment, the fixed column 602 and the extension column 603 are threadedly connected. A bump 604 is fixedly mounted on the bottom end of the extension column 603, and a turntable 605 is mounted on the top end of the fixed column 602. The turntable 605 can be made of aluminum alloy or plastic. Aluminum alloy offers the advantages of lightness and high strength, while plastic has good wear resistance and impact resistance.

[0088] In this embodiment: by rotating the turntable 605, the turntable 605 drives the fixed column 602 to rotate. Since the fixed column 602 is rotatably connected to the inside of the support column 601, and the fixed column 602 and the extension column 603 are threadedly connected, the fixed column 602 rotates in place inside the support column 601, driving the extension column 603 to move inside the fixed column 602, thereby leveling the base 1. At the same time, the protrusion 604 at the bottom end of the extension column 603 can be inserted into the ground, further improving the stability of the device.

[0089] Working principle: When in use, first move the device to the position to be measured, then rotate the turntable 605, the turntable 605 drives the fixed column 602 to move, and the fixed column 602 then drives the extension column 603 to extend from the bottom end of the support rod, and adjust the base 1 to a completely horizontal position. At this time, turn on the motor 402, drive the drill bit 403 to rotate rapidly, so that the drill bit 403 continues to drill deep into the ground. When the drilling is completed, the ground column 501 is aligned with the hole position, and the hand-tightening bolt 11 is turned to release the hand-tightening bolt 11 to release the ground column 501. 01, under the action of gravity, the ground post 501 moves downward from the inside of the beam 3 until the ground post 501 is inserted into the hole, and the expansion head 503 is located at the bottom end of the ground post 501. At this time, the rotating block 506 is rotated again, and the rotating block 506 drives the central pull rod 502 to rotate, and the central pull rod 502 drives the limiting rod 507 to slide in the limiting groove 504. At the same time, the central pull rod 502 drives the metal sheet 508 to open. At this time, the central pull rod 502 can be displaced a short distance inside the ground post 501. When the limiting rod 50 When the limiter 504 moves to the maximum distance, the rotation stops. Since the top of the center rod 502 and the top of the ground post 501 are threaded, the thread can lock the center rod 502, and the metal piece 508 is also fixed at this angle. At this time, the ground post 501 can be completely fixed in the hole. Then the cylinder 7 is activated again to push the horizontal plate 8 to the slope position to be measured. At this time, the pendulum 903 drives the indicator disk 905 to rotate in the measuring disk 902. By observing the indicator disk 905 and the scale The position of the degree groove 904 can be used to obtain the measurement result. When the measurement is completed, rotate the rotating block 506 in the opposite direction. The center pull rod 502 drives the metal sheet 508 to rotate and move upward in the ground column 501. At the same time, the rotating block 506 drives the limiting rod 507 to slide in the limiting groove 504 until the metal sheet 508 is completely closed. At this time, pull the rotating block 506 again to drive the center pull rod 502 and the ground column 501 to move upward through the rotating block 506, and then use the hand-tightening bolts 11 to fix the ground column 501 and the beam 3.

[0090] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
