Description

Technical Field

[0001] The present invention relates to the technical field of stratum detection, and in particular to a stratum structure detection device. Background Art

[0002] Stratum structure detection refers to the technology of obtaining the distribution of underground rock and soil layers (such as depth, thickness, density, etc.) and the morphology of stratigraphic interfaces through non-destructive or destructive means. It is widely used in geological exploration, engineering survey, geological disaster early warning and other fields. Its core is to analyze stratigraphic interface characteristics and structural parameters by transmitting detection signals and receiving reflected waves.

[0003] In the detection of stratum structure, the existing technology mainly relies on electromagnetic wave detection method, which analyzes stratum information by emitting electromagnetic waves and receiving reflected signals. However, due to the complexity and diversity of the stratum structure, especially the existence of inclined strata or irregular strata, there is a problem of inaccurate detection. The electromagnetic wave detection equipment in the existing technology usually includes a transmitting unit, a receiving unit and a signal processing system. The electromagnetic wave transmitting unit and the receiving unit are arranged in a centralized manner. During the detection process, the transmitting unit and the receiving unit must be strictly arranged perpendicular to the ground to ensure that the electromagnetic wave enters the stratum vertically and is reflected back to the receiving end. However, only the stratum depth data in the vertical direction can be obtained, and it is impossible to detect inclined or complex stratum structures, and it is impossible to detect and analyze inclined strata or medium morphology; and the detection probe is usually arranged in a fixed position, which cannot achieve multi-angle detection and multi-level detection, and it is difficult to accurately capture the structural characteristics of uneven strata. At the same time, the unevenness or slope of the stratum will cause the electromagnetic wave reflection path to be uncertain, so that some signals cannot be effectively received, affecting the detection accuracy. There are certain defects, so it is necessary to develop a stratum structure detection device. Summary of the Invention

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and examples.

[0024] Example 1: In the prior art, the transmitting unit and the receiving unit of the detection equipment need to be arranged strictly perpendicular to the ground to ensure that the electromagnetic waves enter the stratum vertically and are reflected back to the receiving end. However, only the stratum depth data in the vertical direction can be obtained, and it is impossible to detect inclined or complex stratum structures, and it is impossible to detect and analyze inclined strata or medium morphology; and the detection probe is usually arranged in a fixed position, which cannot realize multi-angle detection and multi-level detection, and it is difficult to accurately capture the structural characteristics of uneven strata. At the same time, uneven or inclined strata will lead to uncertain electromagnetic wave reflection paths, so that some signals cannot be effectively received, affecting the detection accuracy.

[0025] In view of the above problems, this embodiment provides a ground structure detection device, including a mobile body 1, a detection component 2 and a shaping component 3, such as Figure 1 As shown, guide frames 11 are provided at the front and rear ends of the mobile body 1, and a lifting ring 13 is fixedly installed on the top of the guide frame 11, so that the mobile body 1 can be lifted onto the transport vehicle for transfer, and driving members 14 are provided on the front and rear guide frames 11 respectively. The driving members 14 are electric push rods, which are fixedly installed in the front guide frame 11 and the rear guide frame 11 respectively. The detection component 2 and the shaping component 3 are arranged in the front and rear ends of the body, and the detection component 2 and the shaping component 3 are slidably mounted on the front guide frame 11 and the rear guide frame 11 respectively. The driving member 14 can control the lifting and lowering of the detection component 2 and the shaping component 3, and push handles 12 are also installed on both sides of the body.

[0026] like Figure 2-3As shown, the detection assembly 2 includes an inverted V-shaped frame 21, a synchronous rotation mechanism, a rotating disk 25 and a transmitting and receiving unit. The inverted V-shaped frame 21 is fixed with an inclined top plate and an inclined bottom plate at the top and bottom, and an inverted V-shaped support layer 23 is also fixed in the middle of the inverted V-shaped frame 21. The synchronous rotation mechanism is symmetrically arranged on the support layer 23. The rotating disk 25 is connected to the rotating end of the synchronous rotation mechanism, and the end face of the rotating disk 25 is in contact with the inclined bottom plate of the inverted V-shaped frame 21. The synchronous rotation mechanism is used to control the rotation of the rotating disk 25.

[0027] The synchronous rotation mechanism, which is arranged symmetrically on the left and right sides, can control the left rotating disk 25 and the right rotating disk 25 to rotate synchronously.

[0028] In this embodiment, the synchronous rotation mechanism includes a bearing seat 41, a rotating shaft, a pulley 42, a bevel gear 43 and a handwheel 44. The bearing seat 41 is fixedly mounted on the support layer 23, the rotating shaft is rotatably sleeved in the bearing seat 41, and the bottom of the rotating shaft is fixedly sleeved with the rotating disk 25. The top of the rotating shaft is fixedly mounted with a pulley 42, and the bevel gears 43 are symmetrically mounted on the supporting layer 23. Adjacent bevel gears 43 mesh with each other, and a pulley 42 is also fixedly mounted on the top of the bevel gear 43. The pulley 42 at the top of the rotating shaft and the pulley 42 at the top of the bevel gear 43 are connected by a transmission belt. The handwheel 44 is provided at the top of the inverted V-shaped frame 21, and the handwheel 44 is fixedly connected to the pulley 42 at the top of the bevel gear 43 through a rotating rod 45.

[0029] The bevel gear 43 can be rotated and controlled by the hand wheel 44 so that the left rotating disk 25 and the right rotating disk 25 can rotate completely synchronously. The hand wheel 44 can be used to precisely adjust the rotating disk 25 to achieve the best detection signal.

[0030] The transmitting and receiving unit can adopt the geological radar in the prior art, including a transmitting probe 26, a receiving probe 27 and a signal processing unit;

[0031] like Figure 5-6 As shown, a plurality of transmitting probes 26 and a plurality of receiving probes 27 are radially and obliquely installed in the left rotating disk 25 and the right rotating disk 25 respectively. The transmitting probes 26 and the receiving probes 27 are at an angle to the central axis of the rotating disk 25.

[0032] Slots 251 for mounting a transmitting probe 26 and a receiving probe 27 are respectively provided on the left rotating disk 25 and the right rotating disk 25;

[0033] The transmitting probes 26 and receiving probes 27 of the same radial array on each rotating disk 25 have the same tilt angle, while the transmitting probes 26 and receiving probes 27 of different radial arrays on each rotating disk 25 have different tilt angles.

[0034] That is, a plurality of transmitting probes 26 are radially mounted in the left rotating disk 25. The transmitting probes 26 in the same radial row have the same tilt angle, while the transmitting probes 26 in different radial rows on the left rotating disk 25 have different tilt angles.

[0035] Several receiving probes 27 are radially mounted on the right-hand rotating disk 25. The receiving probes 27 in the same radial row have the same tilt angle, while the receiving probes 27 in different radial rows on the right-hand rotating disk 25 have different tilt angles.

[0036] The transmitting probes 26 and receiving probes 27 with corresponding tilt angles in adjacent rotating disks 25 constitute a transmitting and receiving unit.

[0037] The end face of the rotating disk 25 is attached to the inclined bottom plate of the inverted V-shaped frame 21, and the rotating disk 25 is in an inclined state, but the transmitting probe 26 and the receiving probe 27 still have an inclination relative to the rotating disk 25. The inclination of the transmitting probe 26 and the receiving probe 27 is inclined at a certain angle along the central axis of the rotating disk 25.

[0038] like Figure 4 As shown, the shaping component 3 includes a cone box 31, a vibration motor 32, a soil adding bucket 34 and an inverted V-shaped shaping plate 33. The cone box 31 is symmetrically arranged on the left and right, and the vibration motor 32 is fixedly installed on the top of the cone box 31. The cone box 31 is filled with a vibration-enhancing medium. The vibration-enhancing medium uses round expanded clay to increase the vibration effect. The soil adding bucket 34 is fixedly arranged between adjacent cone boxes 31, and the inverted V-shaped shaping plate 33 is fixedly arranged at the bottom of adjacent cone boxes 31. There is a soil adding port on the top of the soil adding bucket 34, and the output port at the bottom of the soil adding bucket 34 passes through the inverted V-shaped shaping plate 33.

[0039] A guide sleeve 22 is fixedly installed on the circumference of the inverted V-shaped frame 21 and the cone box 31. The inverted V-shaped frame 21 and the cone box 31 can be slidably mounted on the front guide frame 11 and the rear guide frame 11 respectively through the guide sleeve 22. The output end of the electric push rod at the top of the front guide frame 11 is connected to the top of the inverted V-shaped frame 21, and the output end of the electric push rod at the top of the rear guide frame 11 is connected to the top of the cone box 31. In the non-working state, the inverted V-shaped frame 21 and the cone box 31 are both located on the upper side of the guide frame 11.

[0040] The angle of the bottom of the inverted V-shaped frame 21 is the same as the angle of the V-shaped and inverted V-shaped shaping plates 33, both of which are between 165 degrees and 170 degrees.

[0041] To ensure the detection effect, the bottom of the inverted V-shaped frame 21 needs to contact the ground for stratum detection. A V-shaped soil body is excavated in advance on the ground so that the inclined bottom plate at the bottom of the inverted V-shaped frame 21 can fit in with the V-shaped soil body. The inclined bottom plate fits in with the V-shaped soil body on the ground, and the rotating disk 25 fits in with the inclined bottom plate, so as to achieve stratum structure detection with no gap in contact with the ground.

[0042] And considering that the V-shaped soil excavated manually may not fit the bottom shape of the inverted V-shaped frame 21, the V-shaped soil can be shaped by the shaping component 3 so that the shape of the V-shaped soil fits the bottom shape of the inverted V-shaped frame 21; after the V-shaped soil is preliminarily excavated manually, the mobile body 1 moves to align the shaping component 3 with the V-shaped soil, and the vibration motor 32 vibrates to cause the vibration-aiding medium to vibrate and shape the V-shaped soil. During the shaping process, the soil adding bucket 34 can be used to supplement the V-shaped soil, and the V-shaped soil is finally compacted and formed through vibration. Then the mobile body 1 moves to make the bottom of the V-shaped frame fit and contact the V-shaped soil. At this time, it is considered that the bottom of the V-frame is in contact with the ground without a gap.

[0043] When conducting stratum structure detection, the rotating disk 25 rotates synchronously, and only the transmitting probe 26 and the receiving probe 27 of a certain radial array are used each time. The transmitting probe 26 and the receiving probe 27 of the same radial array are facing the direction to be detected. When the rotating disk 25 rotates so that the two ends of any radial array are respectively located at the highest position and the lowest position of the inclined bottom plate of the inverted V-shaped frame 21, the radial array is adjusted to be consistent with the detection direction.

[0044] In this embodiment, four radial arrays of transmitting probes 26 and receiving probes 27 are provided, so the rotating disk 25 only needs to rotate 45 degrees each time. Additional radial arrays can also be added as needed to increase transmitting probes 26 and receiving probes 27 with different inclination angles.

[0045] The scope of the stratum structure detection is a point in the depth direction downward from the vertical line in the middle of the bottom of the inverted V-shaped frame 21, and the stratum structure near the point is detected.

[0046] The bottom inclined plate of the inverted V-shaped frame 21 is a 170-degree conical surface. The angles of the transmitting probes 26 and receiving probes 27 in each radial column in the rotating disk 25 are based on the conical surface and are tilted at a certain angle relative to the central axis of the rotating disk 25.

[0047] like Figure 7 As shown, for example, the transmitting probes 26 and the receiving probes 27 of the A1-A6 and A1"-A6" radial columns are tilted 1 degree relative to the central axis of the rotating disk 25, the transmitting probes 26 and the receiving probes 27 of the B1-B6 and B1"-B6" radial columns are tilted 2 degrees relative to the central axis of the rotating disk 25, and so on. By analogy, the tilt angles of the transmitting probes 26 and the receiving probes 27 of the A radial column, the B radial column, the C radial column, and the D radial column are all different.

[0048] When the transmitting probe 26 and the receiving probe 27 of the A-axis column correspond to the detection direction, the depth point detected by A1A1" is A10, the depth point detected by A2A2" is A20, and so on;

[0049] When the transmitting probe 26 and the receiving probe 27 of the B-diameter column correspond to the detection direction, the depth point detected by B1B1" is B10, the depth point detected by B2B2" is B20, and so on;

[0050] When the transmitting probe 26 and the receiving probe 27 of the C-diameter column correspond to the detection direction, the depth point detected by C1C1" is C10, the depth point detected by C2C2" is C20, and so on;

[0051] When the transmitting probe 26 and the receiving probe 27 of the D-path array correspond to the detection direction, the depth point detected by D1D1" is D10, the depth point detected by D2D2" is D20, and so on;

[0052] That is to say, when the rotating disk 25 rotates and switches the radial series, the detection depth of the next radial series is deeper than that of the previous radial series, and detection is performed in this order, which has the characteristics of gradient detection.

[0053] When the proximal end and distal end of the same diameter array are respectively located at the highest position and the lowest position of the inclined bottom plate of the inverted V-shaped frame 21, the proximal end probe of the same diameter array detects shallow strata, and the distal end probe of the same diameter array detects deep strata. The detection depth between the proximal end probe and the distal end probe gradually increases. The proximal end probe is a high-frequency detection, and the distal end probe is a low-frequency detection, thereby realizing the complete detection of the stratum structure in the entire depth direction.

[0054] By synchronously rotating adjacent rotating disks 25, A1A1", B1B1", C1C1", and D1D1" can be detected at the same position, but the detected strata are at different depths.

[0055] Although A1A1", B1B1", C1C1", and D1D1" are not on the same radial array, they are all proximal depths detected by the rotation adjustment of the rotating disk 25, so they form a proximal ring group, and the subsequent ones are similar.

[0056] When reverse direction detection is required, the mobile vehicle 1 can be turned around and reversed.

[0057] Through the design of gradient dip probe array, formation data at 6 different depths within the vertical range can be obtained in a single operation, improving detection efficiency.

[0058] Example 2: A stratum structure detection device in this embodiment is described centering on the differences from Example 1.

[0059] In this embodiment, the synchronous rotation mechanism adopts another structure, such as Figure 8As shown, the synchronous rotation mechanism includes a synchronous motor 241 and a rotating shaft. The synchronous motor 241 is fixedly mounted on the support layer 23 through a motor seat. The output shaft of the synchronous motor 241 is connected to the rotating shaft 242. The rotating shaft 242 is fixedly mounted on the rotating disk 25. The synchronous motor 241 controls the rotation of the rotating disk 25.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the scope of protection of the present invention.
