Description

Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, and more specifically, to a fully automatic intelligent lightweight power penetration test device. Background Technology

[0002] Dynamic cone penetration testing (DCPT) is an in-situ testing method widely used in geotechnical engineering investigation. It uses a heavy hammer of a certain mass to drive a probe of a specific size into the soil layer through free fall from a certain height. The mechanical properties of the soil are determined by the number of hammer blows required to penetrate to a certain depth.

[0003] Chinese patent application number CN202121238772.0 discloses a lightweight dynamic penetrometer intelligent testing device, including a drop hammer rod, an outer sleeve column at the bottom of the drop hammer rod, an inner sleeve column at the bottom of the outer sleeve column, a penetrometer rod at the bottom of the inner sleeve column, a liftable gravity hammer around the outer ring of the drop hammer rod, a penetrometer probe at the bottom of the penetrometer rod, and an adjustable outer circular plate around the outer ring of the penetrometer rod.

[0004] In the above technical solution, the powered penetrometer provides support and corrects the verticality of the drop hammer, enhancing the accuracy of the test results. Traditional lightweight powered penetrometers require one person to hold the penetrometer rod while another person raises the hammer to a 50cm drop height and allows it to fall freely. The number of hammer blows is recorded for every 30cm penetration. The test is terminated when the number of blows exceeds 100 for 30cm penetration or 50 for 15cm penetration. During the test, the hammer needs to be continuously raised manually, which not only increases the labor intensity for operators but also affects the testing efficiency of the powered penetrometer. Data recording also involves measuring with a tape measure, drawing scale lines, and visual inspection. When encountering complex testing environments where it is difficult for testing personnel to approach the equipment, the data recording may be incomplete, discontinuous, or inaccurate, failing to guarantee the reliability of the final test results. This can ultimately lead to improper soil layer division and unreasonable judgment of soil compaction. Furthermore, the moment the penetrometer hammer strikes the probe rod, the reaction force of the probe rod on the hammer causes the hammer to rise a short distance momentarily before falling again to strike the probe rod. This affects the accuracy of the data on the probe rod's penetration into the ground, and consequently, the accuracy of the overall data recording. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automated, intelligent, lightweight, powered penetration testing device to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fully automatic intelligent lightweight power penetrometer includes a housing and a penetrometer rod installed in the middle of its bottom surface.

[0011] Preferably, the inner side of the rail frame is fixedly installed with toothed plates of the same number as the missing gears. After the toothed plates move, they mesh with the missing gears. The inner side of the connecting frame is provided with multiple vertical frames. The bottom surface of any vertical frame is provided with a through groove. A matching movable plate is slidably connected inside the through groove. A vertical plate is fixedly installed on the surface of the movable plate. The vertical plate is fixedly connected to a limiting block. A trapezoidal block is fixedly installed at one end of the movable plate. The trapezoidal block includes a slope and a plane.

[0012] Preferably, a third spring is elastically connected between the trapezoidal block and the vertical frame, with one end of the third spring fixedly connected to the trapezoidal block and the other end of the third spring fixedly connected to the vertical frame.

[0013] Preferably, a base frame is fixedly installed on the bottom surface of any one of the toothed plates, and a rotating wheel that contacts the slope surface of the trapezoidal block is rotatably connected to the end surface of any one of the base frames.

[0014] Preferably, both the vertical frame and the vertical plate have through holes on their surfaces.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) In use, this fully automatic intelligent lightweight power penetrometer moves downwards via a nut ring, simultaneously moving two support plates, an arc plate, locking blocks, and two rotating plates downwards. When the two locking blocks contact the guide groove, they are pressed against the surface of the guide groove, causing the two arc plates to rotate at the ends of the support plates. When the locking blocks align with the slots, the two rotating plates reset under the action of the first spring, allowing the two locking blocks to reposition and engage with the slots. Subsequently, the motor reverses, rotating the threaded rod, causing the nut ring to move upwards, moving the locking blocks upwards. The upward movement of the locking blocks then moves the concave hammer upwards. When the two rotating plates are pressed and rotated by the guide cone, the two arc plates rotate, causing the two locking blocks to rotate and disengage from the slots. At this point, the concave hammer undergoes free fall and strikes the penetrometer rod, giving the lightweight penetrometer an automatic hammering function. Its lightweight and durable structure reduces the operator's workload, making it suitable for complex geological exploration and improving the efficiency of the penetrometer in geological exploration. It also ensures the integrity, continuity, and accuracy of the geological exploration data.

[0019] 2) When this fully automatic intelligent light-duty power penetration test equipment is in use, the limiting block cannot move upward under the action of the limiting block. During the fall of the concave penetrating hammer, it moves the sliding plate within the fixed frame. The movement of the sliding plate squeezes the limiting block and rotates it downward. After the sliding plate stops squeezing the limiting block, the limiting block instantly resets under the action of the spring shaft. The concave penetrating hammer rises slightly upward immediately after striking the penetration rod, carrying the sliding plate upward. Because the limiting block is restricted by the limiting block, the limiting block reduces the rising distance of the sliding plate, thereby reducing the small rising height of the concave penetrating hammer. This reduces the rising height of the concave penetrating hammer after receiving the reaction force, thus reducing the impact of the concave penetrating hammer on the penetration rod's impact into the ground after it falls again, ensuring the accuracy of the data on the penetration rod's first impact into the ground.

[0020] 3) When this fully automatic intelligent light-duty power penetration test equipment is in use, after the penetration rod completes one hammer strike, the laser displacement sensor records the scale of the penetration rod and transmits the signal to the electrical control equipment. The electrical control equipment then transmits the signal to the mobile phone terminal, which allows personnel to view the data in real time through the mobile phone terminal, avoiding errors caused by manual data collection and making the collected data more accurate.

[0038] Please see Figure 1 - Figure 15A fully automatic intelligent lightweight power probing device includes a housing 1 and a probing rod 2 installed in the middle of its bottom surface. The probing rod 2 is a conventional probing rod in the prior art. A concave through-hammer 3 capable of vertical up-and-down movement is installed inside the housing 1. The concave design of the concave through-hammer 3 facilitates the engagement of a locking block 7 with a locking slot 12. A nut ring 4 capable of vertical up-and-down movement is installed above the concave through-hammer 3. A frame plate 5 is fixedly installed on the surface of the nut ring 4. An arc-shaped plate 6 is rotatably connected to the ends of both frame plates 5. A locking block 7 is fixedly installed on the bottom surface of both arc-shaped plates 6. A rotating plate 8 is fixedly installed on the top surface of both arc-shaped plates 6. A first spring 9 is elastically connected between the two rotating plates 8, and the first spring 9 is used to reset the two rotating plates 8. The inner surface of the housing 1... A guide cone 10 for pressing two rotating plates 8 is fixedly installed on the top surface of the housing 1. A hole is opened in the middle of the guide cone 10. A threaded rod 23 is rotatably connected to the top surface inside the housing 1 through the hole. The threaded rod 23 is rotatably connected to the guide cone 10 through the hole. A guide groove 11 is opened on the surface of the concave through-hole hammer 3. A slot 12 that engages with the slot 7 is opened inside the concave through-hole hammer 3. The slot 12 communicates with the guide groove 11. A fixed bracket 13 communicating with it is fixedly installed on the corresponding outer surface of the housing 1. A connecting bracket 14 communicating with it is fixedly installed on the side of the fixed bracket 13. Multiple spring shafts 15 are rotatably connected to the inner wall of the connecting bracket 14. The spring shafts 15 are conventional spring shafts 15 in the prior art. A missing gear is fixedly installed on the middle surface of any spring shaft 15. 16. A limiting block 17 is fixedly installed on the surface of any missing gear 16. When the limiting block 17 is restricted by the limiting block 18, the small upward height of the concave through-hammer 3 is reduced. When the limiting block 17 rotates into the connecting frame 14, it prevents the limiting block 17 from obstructing the lifting process of the concave through-hammer 3. One end of the limiting block 17 extends into the interior of the fixed frame 13. A limiting block 18 is provided on the top surface of any limiting block 17 for limiting it. The interior of both fixed frames 13 is slidably connected with matching sliding plates 19. Both sliding plates 19 are fixedly connected to the surface of the concave through-hammer 3. The downward movement of the nut ring 4 moves the two frame plates 5, the arc plate 6, the locking block 7 and the two rotating plates 8 downward simultaneously. When the two locking blocks 7 move... After the two blocks 7 come into contact with the guide groove 11, they are pressed against the surface of the guide groove 11, causing the two arc-shaped plates 6 to rotate at the end of the frame plate 5. When the blocks 7 move to the position corresponding to the slot 12, the two rotating plates 8 are reset under the action of the first spring 9, so that the two blocks 7 move back to their original position and engage with the slot 12. Then the motor 25 reverses and drives the threaded rod 23 to rotate, causing the nut ring 4 to move upward, which in turn moves the blocks 7 upward. The upward movement of the blocks 7 moves the concave penetrometer 3 upward. When the two rotating plates 8 are pressed and rotated by the guide cone 10, the two arc-shaped plates 6 rotate, causing the two blocks 7 to rotate and disengage from the slot 12. At this time, the concave penetrometer 3 undergoes free fall and strikes the probe rod 2, giving the lightweight penetrometer an automatic hammering function. The structure is lightweight and durable.This design reduces the workload of operators, is suitable for complex geological exploration, and improves the efficiency of the penetrometer for geological exploration, while ensuring the integrity, continuity, and accuracy of the geological exploration data. Because the limiting block 17 cannot move upwards under the action of the limiting block 18, the concave penetrometer hammer 3 moves with the sliding plate 19 within the fixed frame 13 during its descent. The sliding plate 19 presses against the limiting block 17, causing it to rotate downwards. After the sliding plate 19 stops pressing against the limiting block 17, the limiting block 17 instantly resets under the action of the spring shaft 15. The concave penetrometer hammer 3 then rises slightly upwards after striking the penetrometer rod 2, carrying the sliding plate 19 upwards. Because the limiting block 17 is restricted by the limiting block 18, the limiting block 17 reduces the upward distance of the sliding plate 19, thereby reducing the small upward height of the concave penetrometer hammer 3. This reduces the height the concave penetrometer hammer 3 rises after receiving the reaction force, thus reducing the impact of the concave penetrometer hammer 3 on the penetrometer rod 2's impact into the ground after its subsequent descent, ensuring the accuracy of the data from the initial impact of the penetrometer rod 2 into the ground.

[0039] Please see Figure 2 and Figure 4 One of the support plates 5 has a connecting ring plate 20 fixedly installed on one end surface. A fixing rod 21 is fixedly installed inside the housing 1. The fixing rod 21 is located on one side of the concave hammer 3. A sliding ring 22 is slidably connected to the surface of the fixing rod 21. The sliding ring 22 is fixedly connected to the connecting ring plate 20. A threaded rod 23 is rotatably connected to the middle of the housing 1. The top end of the threaded rod 23 is rotatably connected to the top surface inside the housing 1. The threaded rod 23 is threadedly connected to the nut ring 4. A motor 25 is fixedly installed on the top surface of the housing 1. The output end of the motor 25 is fixedly connected to the threaded rod 23. The threaded connection design between the threaded rod 23 and the nut ring 4 ensures the stability of the concave hammer 3 during the lifting process.

[0040] Please see Figure 2 , Figure 4 and Figure 6 Lightweight hollow brackets 24 are fixedly installed on the corresponding side walls inside the housing 1. The bottom surface of the concave through-hammer 3 has a slot 26 that communicates with the slot 12. A laser displacement sensor 27 is fixedly installed on the bottom surface of the housing 1. The laser displacement sensor 27 is a conventional laser displacement sensor 27 in the prior art. A slot 29 for inserting the probe rod 2 is opened in the middle of the bottom surface of the housing 1. A scale 28 is set on the surface of the probe rod 2. The probe rod 2 is a hollow probe tube. The diameter of the probe rod 2 is larger than the diameter of the slot 26. The slot 26 matches the threaded rod 23, and the slot 26 and the threaded rod 23 are slidably connected.

[0041] Please see Figure 9 , Figure 10 and Figure 11Mounting plates 30 are fixedly installed on the top and bottom surfaces of the connecting frame 14. Sliding sliders 31 are slidably connected inside the two mounting plates 30. A second spring 33 is elastically connected between the slider 31 and the mounting plate 30. One end of the second spring 33 is fixedly connected to the slider 31, and the other end of the second spring 33 is fixedly connected to the mounting plate 30. A rail frame 32 is fixedly installed between the two sliders 31. The rail frame 32 includes a first flat rail, an inclined rail, and a second flat rail from top to bottom. The second spring 33 is used for the slider 31 to return to its original position.

[0042] Please see Figure 12 - Figure 15 The inner side of the rail frame 32 is fixedly equipped with toothed plates 34, the same number as the missing gear 16. After the toothed plates 34 move, they mesh with the missing gear 16. The inner side of the connecting frame 14 is provided with multiple vertical frames 35. The bottom surface of any vertical frame 35 is provided with a through groove 36. The inside of the through groove 36 is slidably connected to a matching movable plate 37. A vertical plate 38 is fixedly installed on the surface of the movable plate 37. The vertical plate 38 is fixedly connected to the limiting block 18. A trapezoidal block 39 is fixedly installed at one end of the movable plate 37. The trapezoidal block 39 includes a slope and a plane. The two lifting rods 48 move downwards, causing the rollers 49 to move on the surface of the rail frame 32. With the threaded rod 2 3. Continue to rotate. At this time, the lifting rod 48 moves and the roller 49 moves to the inclined rail on the surface of the rail frame 32, and squeezes the rail frame 32. At this time, the rail frame 32, after being squeezed, moves the slider 31 in the mounting plate 30 to squeeze the second spring 33. The movement of the rail frame 32 also moves multiple toothed plates 34. The movement of the toothed plates 34 moves the base frame 41 and the rotating wheel 42. The rotating wheel 42 squeezes the slope of the trapezoidal block 39. At this time, the movement of the trapezoidal block 39 moves the moving plate 37 in the slot 36 to squeeze the third spring 40. The movement of the moving plate 37 moves the vertical plate 38 and the limiting block 18. At this time, the limiting block 18 moves to release the limiting block 17.

[0043] Please see Figure 14 and Figure 15 A third spring 40 is elastically connected between the trapezoidal block 39 and the vertical frame 35. One end of the third spring 40 is fixedly connected to the trapezoidal block 39, and the other end of the third spring 40 is fixedly connected to the vertical frame 35. The third spring 40 is used to reset the movement of the trapezoidal block 39.

[0044] A base frame 41 is fixedly installed on the bottom surface of any toothed plate 34, and a rotating wheel 42 that contacts the slope of the trapezoidal block 39 is rotatably connected to the end surface of any base frame 41. The setting of the rotating wheel 42 reduces the friction on the trapezoidal block 39.

[0045] Both the vertical frame 35 and the vertical plate 38 have through holes 44 on their surfaces. A common fixing frame 43 is fixedly installed between the vertical frame 35 and the inner wall of the connecting frame 14. The through holes 44 correspond to the positions of the spring shaft 15. The spring shaft 15 passes through the through holes 44 and is rotatably connected to the inner wall of the connecting frame 14. A fixing crossbar 45 is fixedly installed on the inner side of the vertical frame 35. The surface of the vertical plate 38 has rod holes 46 that match the fixing crossbar 45. The fixing crossbar 45 is slidably connected to the rod holes 46.

[0046] Please see Figure 1 - Figure 7 Vertical grooves 47 are provided on the corresponding surfaces of the housing 1. A matching lifting rod 48 is slidably connected inside each of the two vertical grooves 47. Both lifting rods 48 are fixedly connected to another frame plate 5. Rollers 49 that contact the rail frame 32 are rotatably connected to the end surfaces of the two lifting rods 48. The bottom surface of the housing 1 is supported by an adjustable bracket. The adjustable bracket is existing technology and can be set up by the operator according to the geological exploration environment. It is not shown in the figure.

[0047] Please see Figure 16 An electrical control device 50 is fixedly mounted on the surface of the housing 1. The electrical control device 50 is a conventional electrical control component in the prior art. The electrical control device 50 is electrically connected to the motor 25 via wires and to the laser displacement sensor 27 via wires. The electrical control device 50 includes a main control module, a communication module, a power supply module, and a battery. The main control module, communication module, and power supply module are electrically connected. The main control module is responsible for data processing and command issuance; the communication module realizes data transmission; and the power supply module is connected to the battery, supplying power to the main control module, communication module, and... The laser displacement sensor 27 and the motor 25 are powered. After the probe rod 2 completes one hammer strike, the laser displacement sensor 27 records the scale 28 of the probe rod 2 and transmits the signal to the electrical control device 50. The electrical control device 50 then transmits the signal to the mobile phone terminal, which allows personnel to view the data in real time. This avoids errors caused by manual data collection and makes the collected data more accurate. The connection between the electrical control device 50 and the mobile phone terminal is existing technology. The control of the motor 25 and the laser displacement sensor 27 by the electrical control device 50 is also existing technology and will not be described in detail here.

[0048] The usage steps of this invention are as follows: When using this fully automatic intelligent lightweight power penetrometer, firstly, the penetrometer is transported to the penetrometer location and the penetrometer rod 2 is connected. At this time, the laser displacement sensor 27 records the initial scale of the penetrometer rod 2's scale 28. The electrical control device 50 is connected to a mobile phone via a 4G network. The mobile phone sends instructions to the communication module inside the electrical control device 50. After receiving the operation instructions, the communication module transmits the signals to the main control module. At this time, the main control module inside the electrical control device 50 receives and processes the instructions, controlling the motor 25 to rotate forward, causing the threaded rod 23 to rotate. This causes the nut ring 4 to move downward under the action of the connecting ring plate 20, the fixing rod 21, and the slip ring 22. At this time, the downward movement of the nut ring 4 also moves the two support plates 5, the arc plate 6, the clamping block 7, and the two rotating plates 8 together. As the nut ring 4 moves downwards, the frame plate 5 moves, causing the two lifting rods 48 to move downwards within the vertical groove 47. The two lifting rods 48 move downwards, causing the rollers 49 to move on the surface of the rail frame 32. As the threaded rod 23 continues to rotate, the lifting rods 48 move, causing the rollers 49 to move onto the inclined rail on the surface of the rail frame 32, pressing against it. Under this pressure, the rail frame 32 moves with the slider 31 within the mounting plate 30, pressing against the second spring 33. The movement of the rail frame 32 also causes multiple toothed plates 34 to move, which in turn cause the base frame 41 and the rotating wheel 42 to move. The rotating wheel 42 presses against the slope of the trapezoidal block 39. At this time, the trapezoidal block 39 moves, causing the moving plate 37 to move within the slot 36, pressing against the third spring 40. The movement of plate 37 carries vertical plate 38 and limiting block 18. At this time, the limiting block 18 releases its restriction on limiting block 17. As the rail frame 32 continues to move, the toothed plate 34 continues to move and engages with the missing gear 16. The missing gear 16 rotates under the action of the toothed plate 34, causing the limiting block 17 to rotate upward. When the roller 49 moves to the second flat rail on the surface of the rail frame 32, the toothed plate 34 finishes moving into the connecting frame 14. At this time, the limiting block 17 rotates upward and hides inside the connecting frame 14. The nut ring 4 continues to move downward. The roller 49 keeps moving along the second flat rail of the rail frame 32. When the two locking blocks 7 move and contact the guide groove 11, as the nut ring 4 continues to move downward, the two locking blocks 7 are squeezed by the surface of the guide groove 11, carrying the two arc-shaped plates 6. The end of the frame plate 5 rotates, stretching the first spring 9. When the locking block 7 moves to the position corresponding to the locking slot 12, the two rotating plates 8 reset under the action of the first spring 9, moving the two arc-shaped plates 6 to reset as well. This causes the two locking blocks 7 to reset and engage with the locking slot 12. Subsequently, the motor 25 reverses, causing the threaded rod 23 to rotate, which causes the nut ring 4 to move upward, moving the locking blocks 7 upward. The upward movement of the locking blocks 7 moves the concave through-hole hammer 3 upward. When the nut ring 4 moves upward to its initial position, the lifting rod 48 resets, moving the roller 49 to reset as well. At this time, the roller 49 moves to the first slope rail on the surface of the rail frame 32. The slider 31 resets under the action of the second spring 33, moving the rail frame 32 to reset as well. At this time, the toothed plate 34 resets, causing the missing gear 16 to rotate downward.After the missing gear 16 is reset, as the rail frame 32 continues its reset movement, the rotating wheel 42 resets to the slope of the trapezoidal block 39. The trapezoidal block 39 resets under the action of the third spring 40, causing the limiting block 18 to reset and limit the restricting block 17. At this time, the restricting block 17 cannot move upward under the action of the limiting block 18. As the motor 25 continues to reverse, the roller 49 continues to move on the first slope rail on the surface of the rail frame 32. The nut ring 4 moves upward and continues to move the concave hammer 3 upward. When the two rotating plates 8 are squeezed and rotated by the guide cone 10, the two arc plates 6 rotate and cause the two locking blocks 7 to rotate and disengage from the locking slot 12. At this time, the concave hammer 3 performs free fall and strikes the probe rod 2. During the fall, the concave hammer 3 carries the sliding plate 19 to the fixed frame. Within movement 13, the sliding plate 19 moves, squeezing the limiting block 17. At this time, the limiting block 17 rotates, causing the missing gear 16 and spring shaft 15 to rotate as well. When the sliding plate 19 stops squeezing the limiting block 17, the limiting block 17 instantly resets under the action of the spring shaft 15. The concave hammer 3 strikes the probe rod 2 and then rises slightly upward, causing the sliding plate 19 to move upward. Because the limiting block 17 is restricted by the limiting block 18, the limiting block 17 reduces the rising distance of the sliding plate 19, thereby reducing the slight rising height of the concave hammer 3. After the probe rod 2 completes one strike, the laser displacement sensor 27 records the descent scale of the scale 28 on the surface of the probe rod 2. The laser displacement sensor 27 collects the scale of the scale 28 in real time and transmits the signal to the electrical control equipment 50. The main control module inside the electrical control equipment 50 receives and processes the signals collected by the laser displacement sensor 27. The processed data signals are transmitted to the mobile phone via the communication module. The mobile phone receives, processes, and stores the data in real time and displays it on the screen for staff to view. When the electrical control equipment 50 records that the number of hammer blows for the probe rod 2 to penetrate 30cm into the ground is greater than 100 or the number of hammer blows for penetration 15cm into the ground is greater than 50, the motor 25 stops working, stopping the hammering of the probe rod 2, thus completing the probe operation at that point. In this scheme, the downward movement of the nut ring 4 moves the two support plates 5, the arc plate 6, the locking block 7, and the two rotating plates 8 downward simultaneously. When the two locking blocks 7 contact the guide groove 11, Two locking blocks 7 are pressed against the surface of the guide groove 11, causing the two arc-shaped plates 6 to rotate at the end of the frame plate 5. When the locking blocks 7 move to the position corresponding to the slot 12, the two rotating plates 8 are reset under the action of the first spring 9, so that the two locking blocks 7 move back to their original position and engage with the slot 12. Then, the motor 25 reverses and drives the threaded rod 23 to rotate, causing the nut ring 4 to move upward, which in turn moves the locking blocks 7 upward. The upward movement of the locking blocks 7 moves the concave penetrometer hammer 3 upward. When the two rotating plates 8 are pressed and rotated by the guide cone 10, the two arc-shaped plates 6 rotate, causing the two locking blocks 7 to rotate and disengage from the slot 12. At this time, the concave penetrometer hammer 3 performs free fall and strikes the probe rod 2, giving the lightweight penetrometer an automatic hammering function. The structure is lightweight and durable, reducing the workload of the operator.Adapted to complex geological exploration, this design improves the efficiency of the penetration testing equipment while ensuring the integrity, continuity, and accuracy of the geological data. Because the limiting block 17 cannot move upwards under the action of the limiting block 18, the concave hammer 3, during its descent, carries the sliding plate 19 within the fixed frame 13. The sliding plate 19's movement compresses the limiting block 17, causing it to rotate downwards. After the sliding plate 19 stops compressing the limiting block 17, the limiting block 17 instantly resets under the action of the spring shaft 15. The concave hammer 3, after striking the penetration rod 2, rises slightly upwards, carrying the sliding plate 19 upwards. Because the limiting block 17 is restricted by the limiting block 18, the limiting block 17 then decreases... The rising distance of the small sliding plate 19 reduces the small-amplitude rise of the concave penetrating hammer 3, thus reducing the rise height of the concave penetrating hammer 3 after being subjected to reaction force. This further reduces the impact of the concave penetrating hammer 3 on the penetration rod 2 when it descends again, ensuring the accuracy of the data on the first impact of the penetrating rod 2 into the ground. After the penetrating rod 2 completes one impact, the laser displacement sensor 27 records the scale 28 of the penetrating rod 2 and transmits the signal to the electronic control device 50. The electronic control device 50 then transmits the signal to the mobile phone terminal, allowing personnel to view the data in real time via the mobile phone. This avoids errors caused by manual data collection and makes the collected data more accurate.
