Description

Technical Field

[0001] This invention relates to the field of hydrogeological sampling technology, and in particular to a hydrogeological exploration drilling device. Background Technology

[0002] In hydrogeological exploration, obtaining underground information quickly and accurately is crucial to the reliability of the entire exploration results. Therefore, in order to improve exploration efficiency and ensure the reliability of exploration results, relevant personnel often use drilling equipment to obtain underground soil sample information.

[0003] The drilling equipment currently encounters the following issues during use: 1. In the environment that needs to be explored, there are both relatively flat areas and uneven areas, which often results in the geological exploration drilling equipment not being parallel to the horizontal plane when it is placed, causing the drill bit to be tilted when it enters the ground surface. 2. Existing drilling equipment is limited in use, not easy to move, and inconvenient for workers to drill in different locations in the same area. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a hydrogeological exploration drilling device. It primarily addresses the issue that existing drilling devices are often used in environments that include both relatively flat areas and areas with varying slopes and elevations. This often results in the drilling device not being parallel to the horizontal plane, causing the drill bit to tilt when drilling into the ground. Furthermore, existing drilling devices are relatively limited in use, inconvenient to move, and make it difficult for workers to drill in different locations within the same area.

[0005] (II) Technical Solution To achieve the above objectives, the present invention adopts the following technical solution: A hydrogeological exploration drilling device includes a frame, with grooves on both inner walls of the frame, a movable plate slidably connected within the grooves, a support frame fixedly connected to the upper surface of the movable plate, an L-shaped plate on one side of the support frame, and insertion assemblies for fixing the movable plate on both sides of the L-shaped plate. Two guide rods are fixedly connected to the upper surface of the movable plate, and two sliding sleeves that move along the axial direction of the guide rods are fixedly connected to one side of the L-shaped plate. A drilling assembly is located at the bottom of the L-shaped plate, and a driving assembly for driving the L-shaped plate to move up and down is located on one side of the support frame. The frame has threaded holes at each of its four corners, with threaded rods threaded into the holes. A connecting plate is fixedly connected to the bottom of the threaded rod, and a fixing rod is fixedly connected to the bottom of the connecting plate. Two levels are fixedly connected to the upper surface of the frame.

[0006] Furthermore, the insertion assembly includes two insert brackets, which are respectively fixedly connected to both sides of the L-shaped plate. The upper surface of the frame has multiple through holes, and the insert brackets are inserted into the through holes.

[0007] Based on the aforementioned scheme, the cross-section of the insert is L-shaped, and a cone head is fixedly connected to the bottom end of the insert.

[0008] As a further embodiment of the present invention, the drilling assembly includes a mounting shaft, which is rotatably connected to the top of the L-shaped plate via a bearing. The bottom end of the mounting shaft is connected to a drill rod via a coupling. A helical gear two is keyed to the outer side of the mounting shaft. An installation opening is provided on one side of the L-shaped plate, and a connecting shaft is rotatably connected to the installation opening via a bearing. A helical gear one that meshes with the helical gear two is keyed to the outer side of the connecting shaft. A helical rack is fixedly connected to one side of the support frame, and the helical gear one meshes with the helical rack.

[0009] Furthermore, a through hole is provided on the upper surface of the movable plate, and the drill rod passes through the through hole.

[0010] Based on the aforementioned scheme, the drive assembly includes a support plate, which is fixedly connected to one side of the support frame at the top position. A self-locking motor is fixedly connected to the upper surface of the support plate, and a gear is keyed to one end of the output shaft of the self-locking motor. A U-shaped frame is fixedly connected to the upper surface of the support plate, and a rack is fixedly connected to the inner wall of one side of the U-shaped frame, with the gear meshing with the rack.

[0011] As a further embodiment of the present invention, a rubber ball is fixedly connected to the upper surface of the movable plate at a position inside the slide groove, and a plurality of arc-shaped slots are provided at the top of the slide groove, and the rubber ball is engaged with the arc-shaped slots.

[0012] Furthermore, a lock nut is threaded onto the outer side of the threaded rod, located above the frame.

[0013] The beneficial effects of this invention are as follows: 1. This invention uses a threaded rod and a level in combination. When encountering uneven ground, the height of the fixed rod and the connecting plate can be adjusted by rotating the threaded rod, while the level of the frame can be observed by the level. This allows the frame to remain level on uneven ground and prevents the drill rod from tilting when drilling into the ground.

[0014] 2. In this invention, by setting up a movable plate, the movable plate can slide in the groove, thereby changing the position of the drilling component, which facilitates drilling at different locations in the same area and improves the effectiveness of the drilling device.

[0015] 3. By setting up the insertion component, the present invention fixes the moving plate when it has moved and is drilling through the drilling component, thereby preventing the moving plate from moving during the drilling process and improving the stability of the drilling device.

[0016] 4. In this invention, the rubber ball and the arc-shaped groove are used together to position and fix the moving plate during its movement. This makes it easier for workers to position and move the moving plate and ensures that the insertion assembly can fix the moving plate. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0020] Reference Figures 1-5 A hydrogeological exploration drilling device includes a frame 1. Slide grooves 8 are provided on both inner walls of the frame 1. A movable plate 11 is slidably connected within the slide grooves 8. A support frame 2 is welded to the upper surface of the movable plate 11. An L-shaped plate 6 is provided on one side of the support frame 2. Two guide rods 4 are welded to the upper surface of the movable plate 11. Two sliding sleeves 23 that move along the axial direction of the guide rods 4 are welded to one side of the L-shaped plate 6. A drilling assembly 7 is provided at the bottom of the L-shaped plate 6. The position of the drilling assembly 7 can be changed by moving the movable plate 11 within the slide grooves 8, allowing the drilling assembly 7 to drill at different locations in the same area, thus improving the effectiveness of the drilling device. In this invention, the drilling assembly 7 includes a mounting shaft 25, which is rotatably connected to the top of the L-shaped plate 6 via bearings. A drill rod 27 is connected to the bottom end of the mounting shaft 25 via a coupling. A helical gear 26 is keyed to the outer side of the mounting shaft 25. A mounting opening 21 is provided on one side of the L-shaped plate 6, and a connecting shaft is rotatably connected to the mounting opening 21 via bearings. A helical gear 22, meshing with the helical gear 26, is keyed to the outer side of the connecting shaft. A helical rack 24 is bolted to one side of the support frame 2, and the helical gear 22 meshes with the helical rack 24. A through hole 10 is provided on the upper surface of the moving plate 11, through which the drill rod 27 passes. When drilling is required, the L-shaped plate 6 moves downward along the guide rod 4 via the sliding sleeve 23. During this downward movement, the sliding sleeve 23 causes the helical gear 22 to rotate through the inner mesh of the helical gear 22 and the helical rack 24. The helical gear 22 meshes with the helical gear 26, causing the helical gear 26 to rotate. The helical gear 26 then drives the mounting shaft 25 to rotate, which in turn drives the drill rod 27 to rotate. As the drill rod 27 moves downward, it rotates, allowing it to pass through the through hole 10 and drill into the soil. Then, the L-shaped plate 6 moves upward, causing the drill rod 27 to move downward and reverse, thereby bringing out the soil from the borehole for further drilling. In this invention, a drive assembly 5 for driving the L-shaped plate 6 to move up and down is provided on one side of the support frame 2. The drive assembly 5 includes a support plate 28, which is welded to the top of one side of the support frame 2. A self-locking motor 29 is fixed to the upper surface of the support plate 28 by bolts. The self-locking motor 29 is model S87DT160M4. A gear 32 is keyed to one end of the output shaft of the self-locking motor 29. A U-shaped frame 30 is welded to the upper surface of the support plate 28. A rack 31 is fixed to the inner wall of one side of the U-shaped frame 30 by bolts, and the gear 32 meshes with the rack 31. When the L-shaped plate 6 needs to move, the self-locking motor 29 is started. The self-locking motor 29 drives the gear 32 to rotate. The gear 32 will move the U-shaped frame 30 downward by meshing with the rack 31. The U-shaped frame 30 will push the L-shaped plate 6 to move downward along the guide rod 4 through the sliding sleeve 23. In this invention, threaded holes are provided at all four corners of the frame 1, and threaded rods 14 are threadedly connected to the threaded holes. A connecting plate 18 is welded to the bottom end of the threaded rod 14, and a fixing rod 13 is welded to the bottom of the connecting plate 18. Two levels 9 are fixed to the upper surface of the frame 1 by bolts. When encountering uneven ground, the frame 1 is placed on the ground by the fixing rods 13. At this time, the fixing rods 13 may not be in contact with the ground. Then, the threaded rod 14 is rotated, and the threaded engagement between the threaded rod 14 and the threaded hole will cause the connecting plate 18 and the fixing rods 13 to move downward, so that the fixing rods 13 are in contact with the ground. At the same time, the level 9 on the frame 1 is observed to determine whether the frame 1 is in a horizontal state. If the frame 1 is not in a horizontal state, the threaded rod 14 can be rotated to adjust the height of the fixing rods 13, so that the frame 1 is in a horizontal state. When the frame 1 is in a horizontal state, the frame 1 is pressed down so that the fixing rods 13 are inserted into the soil of the ground, thereby placing the frame 1.

[0021] In this invention, both sides of the L-shaped plate 6 are provided with insertion components for fixing the movable plate 11. The insertion components include two inserts 3, which are welded to both sides of the L-shaped plate 6. The upper surface of the frame 1 is provided with multiple insertion holes 16 that penetrate the frame 1, and the inserts 3 are inserted into the insertion holes 16. The cross-section of the insert 3 is L-shaped, and a cone 20 is welded to the bottom end of the insert 3. When the L-shaped plate 6 moves downward, it will drive the insert 3 to move downward, so that the insert 3 fixes the movable plate 11 through the insertion hole 16 via the cone 20, thereby preventing the movable plate 11 from moving. At the same time, the insert 3 will be inserted into the soil on the ground via the cone 20, thereby providing auxiliary fixation for the frame 1. In this invention, a rubber ball 19 is welded to the upper surface of the movable plate 11 at a position inside the slide groove 8. The top of the slide groove 8 is provided with multiple arc-shaped slots 17, and the rubber ball 19 is engaged with the arc-shaped slots 17. During the movement of the movable plate 11, the rubber ball 19 will be squeezed and deformed, thereby causing the rubber ball 19 to disengage from the arc-shaped slots 17. When the movable plate 11 moves to a position where the rubber ball 19 engages with the next arc-shaped slot 17, the movable plate 11 is positioned and moved, and the movable plate 11 is also auxiliaryly fixed. At the same time, the bracket 3 is aligned with the insertion hole 16, which makes it convenient for the operator to position and move the movable plate 11. In this invention, a locking nut 12 is threadedly connected to the outer side of the threaded rod 14 above the frame 1. After the frame 1 is placed, the locking nut 12 is tightened to lock and fix the threaded rod 14, so that the threaded rod 14 will not easily rotate, thus ensuring the stability of the frame 1.

[0022] Working principle: When encountering uneven ground, place the frame 1 on the ground using the fixing rod 13. At this time, the fixing rod 13 may not be in contact with the ground. Then, rotate the threaded rod 14. The threaded rod 14 will engage with the threaded hole, causing the connecting plate 18 and the fixing rod 13 to move downwards, making the fixing rod 13 contact the ground. At the same time, observe the level 9 on the frame 1 to determine if the frame 1 is level. If the frame 1 is not level, rotate the threaded rod 14 to adjust the height of the fixing rod 13, thereby making the frame 1 level. Once the frame 1 is level, press the frame 1 to insert the fixing rod 13 into the soil, thus placing the frame 1. When drilling is required, the self-locking motor 29 is started, which drives the gear 32 to rotate. The gear 32, through meshing with the rack 31, causes the U-shaped frame 30 to move downward. The U-shaped frame 30 pushes the L-shaped plate 6 downward along the guide rod 4 through the sliding sleeve 23. During the downward movement of the sliding sleeve 23, the helical gear 22 rotates through the inner channel of the helical gear 22 and the helical rack 24. The helical gear 22, through meshing with the helical gear 26, causes the helical gear 26 to rotate. The helical gear 26 drives the mounting shaft 25 to rotate, which in turn drives the drill rod 27 to rotate. As the drill rod 27 moves downward, it rotates, allowing it to pass through the through hole 10 and drill into the soil on the ground. Then, the self-locking motor 29 is started to reverse, causing the drill rod 27 to move downward and reverse, thereby bringing out the soil in the borehole for drilling. As the L-shaped plate 6 moves downward, it will drive the insert 3 to move downward, so that the insert 3 can fix the moving plate 11 through the insertion hole 16 via the cone head 20, thereby preventing the moving plate 11 from moving. At the same time, the insert 3 will be inserted into the soil of the ground through the cone head 20, thereby providing auxiliary fixation for the frame 1. When drilling is required at different locations within the same area, the L-shaped plate 6 moves upward, causing the drill rod 27 to move upward and reset. Simultaneously, the L-shaped plate 6 moves the insert bracket 3 upward, disengaging it from the insertion hole 16. This removes the need to fix the moving plate 11, allowing it to move along the slide groove 8. During this movement, the moving plate 11 compresses the rubber ball 19, causing it to deform and disengage from the arc-shaped slot 17. Once the moving plate 11 moves to a position where the rubber ball 19 engages with the next arc-shaped slot 17, the moving plate 11 is positioned and further secured. The insert bracket 3 aligns with the insertion hole 16. Then, the L-shaped plate 6 moves downward for drilling, and the insert bracket 3 passes through the insertion hole 16 to fix the moving plate 11. This facilitates drilling at different locations within the same area, improving the effectiveness of the drilling device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
