Description

Technical Field

[0001] This invention belongs to the technical field of static cone penetrometers, and particularly relates to a static cone penetrometer suitable for geological disaster exploration. Background Technology

[0002] Static cone penetrometers are used to determine the vertical and horizontal variations of soil strata; to perform mechanical stratification; to determine the bearing capacity of natural foundations and estimate the bearing capacity of single piles; to determine the likelihood of liquefaction in sandy soils; to determine the undrained shear strength of soft soils; and to provide calculation indicators for the bearing capacity of soft soil foundations and slope stability.

[0003] The installation of existing static cone penetrometers typically includes the following steps: Based on the geological exploration site layout requirements, select a suitable location. First, screw two ground anchors into the ground on either side of the test point. Before screwing, dig a V-shaped pit at the anchor location with a shovel, 25-30cm deep. Then, vertically insert the ground anchor into the V-groove and slowly screw it down. While screwing, use an anchor weight to secure the anchor rod, insert two extension rods on either side of the anchor weight, and have two or more people slowly rotate the anchor in a mill-like motion to screw it down. The two anchors should be approximately 0.8m apart. Then, level the ground, lay two wooden pads, and then place the base downwards against the wooden pads. Finally, use clamps to secure the anchors and base, clamping the base together with the clamps, thus completing the installation of the static cone penetrometer.

[0004] The fixing process is quite complex, which is not conducive to improving efficiency, and the ground anchor is prone to tilting when inserted, thus causing deviation. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a static probe suitable for geological disaster exploration. It has the advantages of being less prone to tilting during rotation, reducing deviation, and directly connecting the ground and the base through the helical blades, making the connection more convenient. It solves the problems in the prior art where the fixing process is relatively complicated, which is not conducive to improving efficiency, and the ground anchor is prone to tilting during insertion, thus causing deviation.

[0006] This invention is implemented as follows: a static penetrometer suitable for geological disaster exploration includes a static penetrometer body and a base. The static penetrometer body is fixedly connected to the middle of the upper surface of the base. A cylindrical body is provided through the edge of the base. The cylindrical body is perpendicular to the base, and the inner cavity of the cylindrical body is a cylindrical cavity. A spiral groove is formed on the inner wall of the cylindrical body. It also includes a rod, which is equipped with a driving component for driving the rod to rotate. A spiral blade is surrounded by a spiral blade on the outer periphery of the rod. The pitch of the spiral blade is equal to that of the spiral groove, and the edge of the spiral blade extends into the spiral groove.

[0007] During use, the helical blades rotate in the helical grooves of the cylinder, which makes it less prone to tilting during rotation, reducing deviation. Furthermore, the connection between the ground and the base is made more convenient as the helical blades connect directly to the cylinder.

[0008] In a preferred embodiment of the present invention, the helical blade comprises a lower part, a middle part, and an upper part, wherein the lower part and the middle part are fixedly connected, and the middle part and the upper part are fixedly connected; the lower part is a conical structure with the tip pointing downwards, the upper diameter of the upper part is equal to the diameter of the middle part, the diameter of the upper part is equal to the diameter of the middle part, the blade thickness of the upper part is greater than the blade thickness of the middle part, and both the upper and lower surfaces of the upper part can fit into the helical groove.

[0009] In use, rotating the insertion rod breaks through the soil layer at the bottom and screws it into the soil. Because the bottom and middle sections are thin, the edges are screwed into the soil with minimal pressure, avoiding impact on the soil at the testing location. When the upper part screws into the spiral groove, both the upper and lower surfaces of the upper part fit snugly against the groove, thus fixing the spiral blades and cylinder. This application primarily connects the ground and the base via the spiral blades; therefore, the base exerts less pressure on the soil, reducing the impact on the soil at the testing location.

[0010] In a preferred embodiment of the present invention, the driving component includes a fixing block, which is fixedly connected to the upper end of the insertion rod. The insertion rod has a horizontally arranged rotating hole, and a rotating rod is located in the rotating hole. By rotating the rotating rod, the insertion rod can be rotated.

[0011] In a preferred embodiment of the present invention, the driving component includes an outer frame, a fixed frame, a central gear, an edge gear, a motor, and a connecting gear. The fixed frame is fixedly connected to the outer frame. The central gear is rotatably connected to the fixed frame via a rotating shaft. The edge gears are rotatably connected to the outer frame. There are two edge gears, and they are all equidistant from the central gear. The output end of the motor is fixedly connected to either the central gear or the edge gear. The connecting gear is fixedly connected to the upper end of the insert rod. With the motor's output end fixedly connected to the central gear, during use, the outer frame is held so that both the central gear and the edge gear mesh with the connecting gear. The motor drives the central gear to rotate, thereby rotating the connecting gear. This allows the insert rod to drive the helical blades into or out of the soil. This design makes rotating in or out easier and further limits the movement of the helical blades, preventing them from tilting during rotation.

[0012] As a preferred embodiment of the present invention, the spiral blade has aligned insertion holes, and a positioning rod is inserted into the insertion holes.

[0013] Typically, a smaller pitch and more layers in a helical blade result in a more secure fit after being screwed into the ground, but require many rotations to reach the desired position. Conversely, a larger pitch and fewer layers make installation easier, but less secure. This application allows for a relatively larger pitch in the helical blade. During use, the helical blade is first screwed into the predetermined position in the soil, and then a positioning rod is inserted into the insertion hole to fix the helical blade in place, preventing it from rotating and ensuring a more secure connection between the helical blade and the ground.

[0014] The positioning rod is set as the first screw, and the connecting gear has a first screw hole. The positioning rod and the first screw hole are threaded together. By rotating the positioning rod, the positioning rod can be inserted into the insertion hole.

[0015] As a preferred embodiment of the present invention, the base is provided with a plurality of second screw holes, the outer wall of the cylinder is provided with external threads, and the cylinder is connected to the second screw holes through the external threads.

[0016] This method allows for two main advantages: firstly, by adjusting the height of the cylinder, the base can be pre-supported, effectively leveling it; secondly, it facilitates adjusting the position of the cylinder, thereby adjusting the drilling position of the spiral blades.

[0017] Furthermore, a pointed tip is fixedly connected to the lower end of the cylinder, which can be inserted into the soil to fix the cylinder.

[0018] As a preferred embodiment of the present invention, the outer surface of the cylinder is further provided with annularly spaced toothed grooves, and the outer diameter of the cylinder is equal to the outer diameter of the connecting gear. This arrangement allows both the central gear and the edge gear to mesh with the toothed grooves, thereby enabling rapid installation and disassembly of the cylinder. It should be noted that the two cylinders in the same group must change position simultaneously to allow the driving component to be used.

[0019] As a preferred embodiment of the present invention, the connecting gear has a turning hole, and a lever is slidably disposed in the turning hole. The connecting gear can be rotated by the lever, thereby enabling manual screwing in or out of the helical blade.

[0020] Furthermore, the lever can support the outer frame, thereby enabling the central gear and the edge gear to mesh with the connecting gear. When the connecting gear and the cylinder are in contact, the lever can also be removed, so that the central gear and the edge gear can simultaneously mesh with the connecting gear and the tooth groove, thereby fixing the helical blade.

[0021] In a preferred embodiment of the present invention, the connecting gear has a third screw hole, and the insertion rod has a fourth screw hole communicating with the third screw hole. A plurality of positioning rods are connected by a connecting plate, which has a through hole containing a second screw. A pressure block is fixedly connected to the upper end of the second screw, and the pressure block fits against the connecting plate. The second screw is threadedly connected to the third and fourth screw holes. The connecting gear has a through hole aligned with the insertion hole. With this configuration, the positioning rod can be inserted into the insertion hole by rotating the second screw.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] In this invention, during use, the helical blades rotate in the helical grooves of the cylinder, making it less prone to tilting during rotation, thus reducing deviation. Furthermore, the connection between the ground and the base is made more convenient by directly connecting the helical blades. Attached Figure Description

[0034] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0035] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Please see Figure 1 This invention provides a static penetrometer suitable for geological disaster exploration, comprising a static penetrometer body 1 and a base 2. The static penetrometer body 1 is fixedly connected to the middle of the upper surface of the base 2. A cylindrical body 3 is provided through the edge of the base 2. The cylindrical body 3 is perpendicular to the base 2, and the inner cavity of the cylindrical body 3 is a cylindrical cavity. A spiral groove 4 is formed on the inner wall of the cylindrical body 3. The invention also includes a rod 5, which is equipped with a driving component 6 for driving the rod 5 to rotate. A spiral blade 7 is arranged around the outer periphery of the rod 5. The pitch of the spiral blade 7 and the spiral groove 4 are equal, and the edge of the spiral blade 7 extends into the spiral groove 4.

[0037] When in use, the spiral blade 7 rotates in the spiral groove 4 of the cylinder 3. It is not easy to tilt during rotation, which reduces the deviation. Furthermore, the spiral blade 7 directly connects to the ground and the base 2, making the connection more convenient.

[0038] Please see Figure 2 The helical blade 7 includes a lower part 71, a middle part 72, and an upper part 73. The lower part 71 and the middle part 72 are fixedly connected, and the middle part 72 and the upper part 73 are fixedly connected. The lower part 71 is a conical structure with the tip 31 pointing downwards. The upper diameter of the upper part 73 is equal to the diameter of the middle part 72. The blade thickness of the upper part 73 is greater than that of the middle part 72. Both the upper and lower surfaces of the upper part 73 can fit into the helical groove 4.

[0039] In use, rotating the insertion rod 5 causes the lower part 71 to break through the soil layer and screw into the soil. Because the lower part 71 and the middle part 72 are thin, the edges screw into the soil layer with minimal pressure, avoiding impact on the soil layer at the detection location. When the upper part 73 screws into the spiral groove 4, both the upper and lower surfaces of the upper part 73 can fit into the spiral groove 4, thereby fixing the spiral blade 7 and the cylinder 3. This application mainly connects the ground and the base 2 through the spiral blade 7; therefore, the pressure of the base 2 on the soil layer is relatively small, reducing the impact on the soil layer at the detection location.

[0040] For example, the driving component 6 includes a fixing block, which is fixedly connected to the upper end of the insertion rod 5. The insertion rod 5 has a horizontally arranged rotating hole, and a rotating rod is located in the rotating hole. By rotating the rotating rod, the insertion rod 5 can be rotated.

[0041] In another embodiment, please refer to Figure 2 The driving component 6 includes an outer frame 61, a fixing frame 62, a central gear 63, an edge gear 64, a motor 65, and a connecting gear 66;

[0042] The fixing frame 62 is fixedly connected to the outer frame 61. The central gear 63 is rotatably connected to the fixing frame 62 via a rotating shaft. The edge gear 64 is rotatably connected to the outer frame 61. There are two edge gears 64, and they are all equidistant from the central gear 63. The output end of the motor 65 is fixedly connected to the central gear 63 or the edge gear 64. The connecting gear 66 is fixedly connected to the upper end of the plug rod 5.

[0043] For example, the output end of the motor 65 is fixedly connected to the central gear 63. In use, the outer frame 61 is held so that the central gear 63 and the edge gear 64 are both engaged with the connecting gear 66. The motor 65 drives the central gear 63 to rotate, thereby causing the connecting gear 66 to rotate. This allows the helical blade 7 to be driven into or out of the soil via the insertion rod 5. This design makes it easier to rotate in or out and also further limits the movement of the helical blade 7 to prevent it from tilting when rotating in.

[0044] For example, the outer frame 61 is set as an elliptical block or a rhomboid frame, such as the elliptical frame shown in the figure. It should be noted that the two helical blades 7 rotate in opposite directions.

[0045] Please see Figure 2 The spiral blade 7 has aligned insertion holes 74, and a positioning rod 75 is inserted into the insertion holes 74.

[0046] Normally, a smaller pitch and more layers in the helical blade 7 result in a more secure fit after being screwed into the ground, but require many rotations to reach the preset position. A larger pitch and fewer layers make installation easier, but less secure. This application allows for a relatively larger pitch in the helical blade 7. During use, the helical blade 7 is first screwed into the preset position in the soil, and then the positioning rod 75 is inserted into the insertion hole 74, thus fixing the helical blade 7 in place and preventing it from rotating, resulting in a more secure connection between the helical blade 7 and the ground.

[0047] For details, please refer to Figure 8 and Figure 9 In one embodiment, the positioning rod 75 is configured as a first screw, and the connecting gear 66 has a first screw hole 8. The positioning rod 75 and the first screw hole 8 are threaded together. By rotating the positioning rod 75, the positioning rod 75 can be inserted into the insertion hole 74.

[0048] Please see Figures 3-5 The base 2 is provided with several second screw holes 9, and the outer wall of the cylinder 3 is provided with external threads 10. The cylinder 3 is connected to the second screw holes 9 through the external threads 10. In this way, on the one hand, the height of the cylinder 3 can be adjusted to support the base 2 in advance, thus achieving the effect of leveling the base 2. On the other hand, it is convenient to adjust the position of the cylinder 3, thereby adjusting the drilling position of the helical blade 7.

[0049] Furthermore, a pointed tip 31 is fixedly connected to the lower end of the cylinder 3, which can be inserted into the soil to fix the cylinder 3.

[0050] Please see Figure 5 Furthermore, the outer surface of the cylinder 3 is provided with annularly spaced toothed grooves 11, and the outer diameter of the cylinder 3 is equal to the outer diameter of the connecting gear 66. This arrangement allows the central gear 63 and the peripheral gear 64 to mesh with the toothed grooves 11, thereby enabling the cylinder 3 to be quickly installed and disassembled. It should be noted that the two cylinders 3 in the same group must change position simultaneously to allow the driving component 6 to be used.

[0051] Please see Figure 6 The connecting gear 66 has a turning hole 12, and a lever 13 is slidably disposed in the turning hole 12. The connecting gear 66 can be rotated by the lever 13, thereby enabling manual screwing in or out of the spiral blade 7.

[0052] Furthermore, the lever 13 can support the outer frame 61, thereby enabling the central gear 63 and the edge gear 64 to mesh with the connecting gear 66. When the connecting gear 66 and the cylinder 3 are in contact, the lever 13 can also be removed, so that the central gear 63 and the edge gear 64 can simultaneously mesh with the connecting gear 66 and the tooth groove 11, thereby fixing the spiral blade 7.

[0053] Please see Figure 7 The connecting gear 66 has a third screw hole 14, and the insertion rod 5 has a fourth screw hole 15 communicating with the third screw hole 14. Several positioning rods 75 are connected by a connecting plate 16. The connecting plate 16 has a through hole 17, and a second screw 18 is inserted into the through hole 17. A pressure block 19 is fixedly connected to the upper end of the second screw 18, and the pressure block 19 fits against the connecting plate 16. The second screw 18 is threadedly connected to the third screw hole 14 and the fourth screw hole 15. The connecting gear 66 has a through hole 20, which is aligned with the insertion hole 74. With this configuration, the positioning rod 75 can be inserted into the insertion hole 74 by rotating the second screw 18.

[0054] Working principle of the invention:

[0055] When in use, the spiral blade 7 rotates in the spiral groove 4 of the cylinder 3. It is not easy to tilt during rotation, which reduces the deviation. Furthermore, the spiral blade 7 directly connects to the ground and the base 2, making the connection more convenient.
