Technical Field

[0001] The invention belongs to the technical field of geological detection equipment and relates to a drilling device for detecting hydraulic and environmental geology. Background Art

[0002] Hydrogeological and environmental geological survey is the abbreviation of engineering, environmental and hydrogeological survey. With the large-scale exploitation of energy, the world is currently facing an increasingly serious energy crisis, which has also brought great damage to the geological environment. In order to effectively solve the problems of energy utilization and environmental protection, realize the effective investigation and evaluation of hydrology, engineering and environmental geology, carry out hydrogeological and environmental geological survey, make full use of the effective application of hydrogeological and environmental geological survey technology in geological work, comprehensively improve the quality and efficiency of geological survey work, and thus lay a good foundation for the development of my country's social economy.

[0003] At present, generally speaking, the most commonly used geological exploration method is to sample and study the soil layer. The shallow soil can be collected manually using tools such as shovels, and the deep soil is collected by mechanical drive, so that the collection rod is drilled into the soil to a certain depth, and then the soil column in the rod is taken out, laid flat for observation, and cut and sampled as needed to detect and analyze the composition of the soil. However, most of the commonly used collection rods are open at the bottom and directly inserted into the soil layer to collect soil. In order to facilitate the drilling of the collection rod, the bottom of the rod body is set to a tip, and the side opening is used to collect soil. However, no matter which collection method is used, only a single-line or single-point collection effect can be achieved, so that the collected soil cannot meet the precise detection requirements, resulting in a decrease in the detection accuracy of the geological soil layer.

The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0044] Example 1

[0045] like Figure 1 - Figure 2As shown, a drilling device for detecting hydraulic and environmental geology includes a base plate 1, an L-shaped mounting plate 2, a drill rod 3, four moving wheels 4, a lifting plate 6, a guide hole 12 and a drill bit 13. The base plate 1 is used for supporting and installing the entire device. The four moving wheels 4 are respectively arranged at the four corners of the bottom of the base plate 1 for moving the entire device. The L-shaped mounting plate 2 is fixedly connected to one side of the top of the base plate 1. The lifting plate 6 is slidably connected to the inner side of the L-shaped mounting plate 2. The top of the base plate 1 is fixedly connected with a lead screw motor 8. The output end of the lead screw motor 8 is fixedly connected with a lifting screw 9. The top thread of the lifting screw 9 penetrates the top of the lifting plate 6 and is rotatably connected to the bottom of the L-shaped mounting plate 2. The top of the base plate 1 is symmetrically fixedly connected with two slide bars 5. The top ends of the two slide bars 5 both slide through the top of the lifting plate 6 and are fixedly connected to the bottom of the L-shaped mounting plate 2. Start the lead screw motor 8 to drive the lifting screw 9 to rotate, which can drive the lifting plate 6 to slide up and down on the two slide bars 5, thereby achieving the effect of moving the lifting plate 6 up and down. The drill rod 3 is connected to the top side of the lifting plate 6 by rotation. The top of the lifting plate 6 is fixedly connected with a servo motor 7. The output shaft of the servo motor 7 rotates through the bottom of the lifting plate 6 and is fixedly sleeved with a small gear 11. The outer wall of the drill rod 3 is fixedly sleeved with a large gear 16 meshing with the small gear 11. A guide hole 12 is opened on the top side of the bottom plate 1 for the bottom end of the drill rod 3 to pass to the bottom of the bottom plate 1. The drill bit 13 is integrally arranged at the bottom end of the drill rod 3 for drilling the soil. When the servo motor 7 is started, the drill rod 3 can be driven to rotate through the meshing movement of the small gear 11 and the large gear 16. At the same time, in conjunction with the downward movement of the lifting plate 6, the drill rod 3 can be driven to rotate and move downward. The drill rod 3 passes through the guide hole 12 and contacts the soil through the drill bit 13, thereby achieving the effect of drilling the soil and inserting the drill rod 3 into the soil.

[0046] In one aspect of this embodiment, a counterweight 10 is fixedly connected to the top edge of the bottom plate 1 away from the guide hole 12. The counterweight 10 can make the entire device more stable during movement or drilling, preventing rollover or tilting during drilling.

[0047] The present invention can be used in the field of drilling devices for hydraulic engineering, environmental geology, and can also be applied to other fields of the present invention.

[0048] Example 2

[0049] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8As shown, a drilling device for detecting hydraulic geotechnical environment also includes a soil collection mechanism arranged inside the drill rod 3, which is used to collect soil when the drill rod 3 is inserted into the soil; the soil collection mechanism includes an installation cavity 15 opened inside the drill rod 3, a first rotating rod 19 is rotatably connected to one side of the bottom inner wall of the installation cavity 15, a plurality of fixing rings 21 are equidistantly fixedly sleeved on the outer wall of the first rotating rod 19, one side of the plurality of fixing rings 21 are fixedly connected to an arc-shaped collection tube 24 through a connecting rod 23, one end of the plurality of arc-shaped collection tubes 24 are sealed and slidably penetrate one side of the drill rod 3, and are kept flat with the outer side surface of the drill rod 3, an arc-shaped collection groove 26 is opened on one end of the arc-shaped collection tube 24 penetrating the drill rod 3, the top end of the first rotating rod 19 is rotatably penetrated through the top end of the drill rod 3 and is fixedly sleeved with a driven gear 20, the top end of the drill rod 3 is fixedly connected to a driving motor 17, and a driving gear 22 meshing with the driven gear 20 is fixedly sleeved on the output shaft of the driving motor 17. When the drill rod 3 drills to a certain depth, the positions of the multiple arc-shaped collection tubes 24 are all located inside the soil. Then the drive motor 17 is started, and the meshing movement of the active gear 22 and the driven gear 20 can drive the first rotating rod 19 to rotate, and at the same time drive the multiple fixed rings 21 to rotate, and then drive the multiple arc-shaped collection tubes 24 to rotate with the first rotating rod 19 as the center through the connecting rod 23. Since the first rotating rod 19 and the drill rod 3 are eccentrically arranged, the arc-shaped collection tubes 24 can be driven to extend outward and insert into the soil in an arc shape to collect the soil in an arc shape. Compared with the traditional linear insertion collection method, it can not only penetrate into the soil to a certain depth, but also through the circular collection method, it can make the collection range wider, thereby further improving the accuracy of subsequent soil layer research.

[0050] In one aspect of the present embodiment, a block 27 is provided at the opening of the arc-shaped collection groove 26, and the outer side surface of the block 27 is kept flat with the outer end of the arc-shaped collection tube 24, and the inner side surface of the block 27 is fixedly connected with an arc-shaped rod 28, and the other end of the arc-shaped rod 28 passes through the inner end of the arc-shaped collection tube 24 and is kept flat with the inner end of the arc-shaped collection tube 24. By setting the block 27, the arc-shaped collection groove 26 can be temporarily blocked, and its outer side surface is kept flat with the outer end of the arc-shaped collection tube 24, and the outer end of the arc-shaped collection tube 24 is kept flat with the outer side surface of the drill rod 3. Therefore, when the block 27 blocks the arc-shaped collection groove 26, the outer surface of the entire drill rod 3 can be kept in a flat and sealed state, which is convenient for the overall downward drilling inside the soil, and at the same time, it can prevent the upper layer of soil from falling into the arc-shaped collection groove 26, which affects the subsequent research and judgment of the geological soil layer; when the first rotating rod 19 rotates to drive the arc-shaped collection tube 24 to collect soil, the arc-shaped collection groove 26 is temporarily blocked, and the outer side surface of the block 27 is kept flat with the outer end of the arc-shaped collection tube 24, and the outer end of the arc-shaped collection tube 24 is kept flat with the outer side surface of the drill rod 3. Therefore, when the block 27 blocks the arc-shaped collection groove 26, the outer surface of the entire drill rod 3 can be kept in a flat and sealed state, which is convenient for the overall downward drilling inside the soil, and at the same time, it can prevent the upper layer of soil from falling into the arc-shaped collection groove 26, which affects the subsequent research and judgment of the geological soil layer; when the first rotating rod 19 rotates to drive the arc-shaped collection tube 24 to collect soil During collection, the blocking block 27 can be automatically pushed inward by squeezing the soil, and the other end of the arc rod 28 can be driven to move outward and extend. When the collection is completed, the first rotating rod 19 drives the arc collection tube 24 to recycle and rotate. At this time, the extended part of the arc rod 28 also rotates and moves with the arc collection tube 24. Since a certain distance is reserved between the inner end of the arc collection tube 24 and the inner wall of the installation cavity 15, the distance can just meet the extension movement of the arc rod 28. Therefore, it will not cause squeezing and pushing effects on the collected soil, and the collected soil can be completely stored in the arc collection groove 26.

[0051] After the entire device is used, the blocking block 27 and the arc rod 28 can be taken outward, and the soil in the blocking block 27 and the arc collection groove 26 can be cleaned. Since the outer side surface of the blocking block 27 and the outer end surface of the arc collection tube 24 are in a flat state, in order to facilitate the removal of the blocking block 27, the blocking block 27 can be made of iron material and taken outward by the magnetic attraction of the magnet. After the cleaning is completed, the arc rod 28 can be pushed inward along the arc collection groove 26 to complete the installation, thereby making the entire device more flexible and convenient to use.

[0052] Example 3

[0053] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.10As shown, a plurality of sets of fixing rods 29 are fixedly connected to the inner wall of one side of the installation cavity 15, and the number of each set of fixing rods 29 is two, and the same stop block 30 is slidably sleeved on each set of fixing rods 29, and a plurality of arc-shaped collection tubes 24 are fixedly connected to a support block 25 that contacts and cooperates with the stop block 30 on one side near the inner end. Through the contact and cooperation between the support block 25 and the stop block 30, when the arc-shaped collection tube 24 is rotated inwardly and retracted, the outer end of the arc-shaped collection tube 24 can be kept flat with the outer side surface of the drill rod 3, which plays a role in limiting the movement, and at the same time, it will not cause resistance to the extended end of the arc-shaped rod 28; a second rotating rod 34 is rotatably connected to one side of the bottom wall of the installation cavity 15, and the top end of the second rotating rod 34 rotates through the top end of the drill rod 3 and is fixedly connected to a rotating handle 36, and a plurality of transmission gears 35 are equidistantly fixedly sleeved on the outer wall of the second rotating rod 34, and a rack 33 meshing with the corresponding transmission gear 35 is fixedly connected to one side of the plurality of stop blocks 30. The second rotating rod 34 can be rotated by rotating the rotating handle 36, and the stop block 30 can be driven to move on the fixed rod 29 through the meshing movement of the rack 33 and the transmission gear 35; when the stop block 30 contacts the inner wall of the installation cavity 15, it can always maintain the state of interference with the support block 25; before starting to drill downward into the drill rod 3, the rotating handle 36 is first rotated to drive the stop block 30 to move, so that one side of the stop block 30 conflicts with the inner end of the arc-shaped collection tube 24, so that one end of the arc rod 28 can be limited by interference. Therefore, in the process of drilling the drill rod 3 downward, the blocking block 27 will not move inward due to external squeezing force, so that the arc-shaped collection groove 26 can always be kept sealed, and other soil will not enter the arc-shaped collection groove 26, thereby improving the accuracy of subsequent detection; when the arc-shaped collection tube 24 has collected the soil and rotated for recovery, the rotating handle 36 is rotated again to drive the stop block 30 to move and reset , when it conflicts with the inner wall of the installation cavity 15, it stops rotating. At this time, the support block 25 can conflict with the blocking block 30, but will not cause movement obstruction to the extended part of the arc rod 28; when the drill rod 3 is taken out, the collected soil needs to be taken out. At this time, the drive motor 17 can be started first to drive one end of the arc collection tube 24 to extend out of the drill rod 3, in a collecting state, and then the handle 36 is rotated to drive the blocking block 30 to move, so that the blocking block 30 can resist the inner end of the arc rod 28, and then the drive motor 17 is started again to drive the arc collection tube 24 to rotate and recover. In this process, since the inner end of the arc rod 28 is resisted by the blocking block 30, the arc rod 28 and the blocking block 27 will not move synchronously with the arc collection tube 24. Therefore, when the arc collection tube 24 moves relatively inward, the soil collected in the arc collection groove 26 can be automatically pushed outward, thereby achieving the effect of soil removal.

[0054] In one aspect of this embodiment, two sliding grooves 31 are provided inside each of the plurality of stoppers 30, and the ends of the plurality of fixed rods 29 away from the mounting cavity 15 extend into the corresponding sliding grooves 31 and are fixedly connected to the limiting blocks 32. Through the cooperation between the sliding grooves 31 and the limiting blocks 32, the moving distance of the stoppers 30 can be limited, so as to avoid the stoppers 30 from sliding away from the fixed rods 29 during the rotation of the handle 36, thereby ensuring the normal use of the device.

[0055] Example 4

[0056] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.11 As shown, a drilling device for detecting hydraulic and environmental geology also includes a soil collecting seat 14 used in conjunction with the drill rod 3. One side of the soil collecting seat 14 is provided with an arc surface that fits closely with the outer side surface of the drill rod 3, and the arc surface is vertically equidistantly provided with multiple soil collecting grooves 18 used in conjunction with corresponding arc-shaped collection tubes 24. After collecting the soil, start the screw motor 8 to drive the lifting screw 9 to rotate, thereby driving the lifting plate 6 to move upward, and at the same time move the drill rod 3 upward to the highest position. At this time, the drill bit 13 is just located in the guide hole 12, and the lowest arc-shaped collection tube 24 is also located above the bottom plate 1. Then place the soil collecting seat 14 on the top of the bottom plate 1, and make its arc surface fit with the outer side surface of the drill rod 3, and the soil collecting groove 18 corresponds to the position of the arc-shaped collection tube 24. Then start the driving motor 17 to drive the arc-shaped collection tube 24 to extend outward and extend just in the soil collecting groove 18. Then, when rotating and recovering, the collected soil is automatically pushed out and all falls into the soil collecting groove 18, thereby completing the collection of the soil. Finally, take down the soil collecting seat 14 and place it horizontally so that the opening of the soil collecting groove 18 faces upward. After that, you only need to take out the soil in the corresponding soil collecting groove 18 for testing.

[0057] In one aspect of the present embodiment, two arc-shaped support blocks 37 are fixedly connected to the bottom of the soil collection seat 14, and two annular positioning grooves 38 are provided on the top of the bottom plate 1, and the two annular positioning grooves 38 are arranged at the same center as the guide hole 12, and are respectively used in conjunction with the two arc-shaped support blocks 37. The two arc-shaped support blocks 37 are aligned with the two annular positioning grooves 38 and inserted downward, so that the soil collection seat 14 can be positioned and placed, so that the arc-shaped surface of the soil collection seat 14 can be exactly fitted with the outer side surface of the drill rod 3, and the stability of the placement of the soil collection seat 14 can be improved, and it can be prevented from tipping over during the collection process, which affects the collection of soil; through the cooperation of the arc-shaped support blocks 37 and the annular positioning grooves 38, the rotation adjustment of the soil collection seat 14 can also be facilitated, and the use is more convenient.

[0058] However, as is well known to those skilled in the art, the working principles and wiring methods of the servo motor 7, the screw motor 8 and the drive motor 17 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
