Description

Technical Field

[0001] This utility model belongs to the technical field of engineering geological survey equipment, specifically relating to a borehole exploration device. Background Technology

[0002] In fields such as geological exploration and cultural relic protection surveys, when internal fissures are developed in underground rock masses or rock walls, the rock mass quality is poor. Under engineering loads, such as excessive dam weight, excessive settlement of the dam foundation can lead to uneven settlement and cracking of the dam body, or excessive surrounding rock pressure can damage the support structure and cause tunnel collapse. Similarly, the development of internal fissures in the rock walls of rock relic sites affects the stability of the rock mass, causing block slippage, collapse, and spalling.

[0003] Therefore, borehole exploration is a common method, aiming to determine the development of fractures within the borehole to assess rock mass stability and provide a basis for designing rock mass reinforcement schemes. However, during actual drilling, the concealed nature of fractures on the rock walls inside the borehole makes direct observation difficult, and it is impossible to determine the depth and angle of the fractures on the rock walls. Therefore, using appropriate borehole photography or video recording methods to obtain the depth and angle of the fractures on the rock walls becomes a key to solving the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a drilling and exploration device to detect the state of rock wall fissures in a hole under concealed conditions.

[0005] The technical solution adopted by this utility model is a drilling and probing device, including a hollow probe rod. A lens bracket is installed at one end of the probe rod, and a camera is installed on the lens bracket. A wire is threaded through the probe rod, with one end of the wire connected to the camera and the other end of the wire passing through the probe rod and connected to a controller. The controller is connected to a display. A pointer is fixed to the outer periphery of the other end of the probe rod, and a scale is fitted on the outer periphery of the probe rod near the pointer position. The scale is fixed to the borehole opening by an elastic wedge. Several retaining rollers are fitted on the outer periphery of the probe rod.

[0006] The present invention is further characterized in that,

[0007] A handle is fixed to the end of the probe that is away from the lens bracket.

[0008] The upper surface of the dial is marked with angles, and the lower surface of the dial is fixed to the elastic wedge.

[0009] The elastic wedge has a probe hole in the center for the probe rod to pass through. The diameter of the probe hole is larger than the diameter of the probe rod. The elastic wedge is clamped to the borehole opening with an interference fit.

[0010] The probe consists of several hollow rods, each with a female thread at one end and a male thread at the other end. The hollow rods are connected by threaded joints, and each hollow rod is marked with graduations on its outer circumference with an accuracy of 1 cm.

[0011] The probe and the lens bracket are secured together by clips and tightened with nuts.

[0012] The clip has threads on both the inner and outer walls at one end. The inner wall is threaded to the outer circumference of the probe end, and the outer wall is threaded to the nut. The lens bracket is inserted into the other end of the clip. A through groove is opened on the side of the clip along the axial direction. The width of the through groove is the same as the diameter of the wire.

[0013] The camera includes a foreground lens mounted on the top of the lens bracket and a side view lens mounted on one side of the lens bracket near the top. The foreground lens and the side view lens are connected to the controller via wires.

[0014] LED lights are installed on the lens bracket below the foreground lens and below the side lens, and the LED lights are electrically connected to the controller.

[0024] Example 1

[0028] Several retaining rings 6 are sleeved on the outer periphery of the probe rod 5. The retaining rings 6 are fixed to the probe rod 5 by keyways. The outer periphery of the retaining rings 6 is close to the inner wall of the borehole 15. When probing inside the borehole 15, the probe rod 5 and the camera can always be in the center of the borehole 15, which facilitates image processing and information extraction.

[0029] A pointer 9 is fixed to the outer periphery of the other end of the probe rod 5, and the pointer 9 is locked onto the probe rod 5 through a keyway.

[0030] A scale 8 is fitted around the outer periphery of the probe 5 near the pointer 9. The scale 8 is a detachable scale, which is fixed to the borehole 15 by an elastic wedge 7, so that the detachable scale 8 is fixed and cannot be rotated.

[0031] The probe 5, chuck 6, and pointer 9 are rigidly connected. The pointer 9, probe 5, chuck 6, and camera rotate synchronously, while the dial 8 remains stationary. This allows for recording the readings of the pointer 9 on the dial 8 during image capture, thus obtaining the borehole wall angle at the fracture location. This facilitates analysis of the spatial distribution and orientation of the fracture from the side-view lens 2 image. The structure is simple, and the calculation of the borehole wall angle and depth at the fracture location is convenient, straightforward, and cost-effective.

[0032] Example 2

[0033] The drilling and probing device of this utility model has the following structure: Figure 1 As shown, the device includes a detachable hollow probe rod 5, which comprises several hollow rods, each 1 meter long. The outer surface of each rod has graduations, with the smallest graduation being 1 cm, allowing for determination of the corresponding borehole depth for lens imaging. Each hollow rod has a female thread at one end and a male thread at the other. The hollow rods are connected by these threads, allowing the number of hollow rods to be selected based on the borehole depth, facilitating borehole probing operations.

[0034] A lens bracket is installed at the front end of the probe rod 5, and a camera is installed on the lens bracket. A wire 11 is threaded through the probe rod 5.

[0036] Several retaining rings 6 are sleeved on the outer periphery of the probe rod 5. The retaining rings 6 are fixed to the probe rod 5 by keyways. The outer periphery of the retaining rings 6 is close to the inner wall of the borehole 15. When probing inside the borehole 15, the probe rod 5 and the camera can always be in the center of the borehole 15, which facilitates image processing and information extraction.

[0037] A pointer 9 is fixed to the outer periphery of the other end of the probe rod 5, and the pointer 9 is locked onto the probe rod 5 through a keyway.

[0038] A scale 8 is fitted around the outer periphery of the probe 5 near the pointer 9. The scale 8 is a detachable scale, which is fixed to the borehole 15 by an elastic wedge 7, so that the detachable scale 8 is fixed and cannot be rotated.

[0039] The probe 5, chuck 6, and pointer 9 are rigidly connected. The pointer 9, probe 5, chuck 6, and camera rotate synchronously, while the scale 8 remains stationary. This allows the pointer 9 to record the corresponding reading on the scale 8 during image capture, thus obtaining the borehole wall angle at the fracture location. This facilitates the analysis of the spatial distribution and orientation of the fracture from the image captured by the side view lens 2.

[0040] Furthermore, a handle 10 is fixedly connected to the rear end of the probe 5. By rotating the handle 10, the pointer 9, probe 5, chuck 6, and camera rotate synchronously. When the camera takes a picture, it records the reading of the separable dial 8 corresponding to the pointer 9 to obtain the orientation of the borehole wall in the picture.

[0041] The probe rod 5 and the lens bracket are secured together by clip 3 and tightened by nut 4. Figure 3 As shown, one end of the clip 3 has threads on both the inner and outer walls. The inner wall is threaded to the outer circumference of the probe rod 5, and the outer wall is threaded to the nut 4. The lens bracket is inserted into the other end of the clip 3.

[0042] Example 3

[0043] The drilling and probing device of this utility model has the following structure: Figure 1 As shown, the device includes a detachable hollow probe rod 5, which comprises several hollow rods, each 1 meter long. The outer surface of each rod has graduations, with the smallest graduation being 1 cm, allowing for determination of the corresponding borehole depth for lens imaging. Each hollow rod has a female thread at one end and a male thread at the other. The hollow rods are connected by these threads, allowing the number of hollow rods to be selected based on the borehole depth, facilitating borehole probing operations.

[0044] A lens bracket is installed at the front end of the probe rod 5, and a camera is installed on the lens bracket. A wire 11 is threaded through the probe rod 5. One end of the wire 11 is connected to the camera, and the other end of the wire 11 passes through the center of the probe rod 5 and is connected to a controller 13. The controller 13 is connected to a display 12. The controller 13 transmits control signals to the camera through the wire 11 to control the camera to take pictures. The image captured by the camera is displayed on the display 12.

[0045] The camera includes a foreground lens 1 mounted on the top of the lens bracket and a side view lens 2 mounted on one side of the lens bracket near the top. The foreground lens 1 and the side view lens 2 are respectively connected to the controller 13 via wires 11.

[0046] Several retaining rings 6 are sleeved on the outer periphery of the probe rod 5. The retaining rings 6 are fixed to the probe rod 5 by keyways. The outer periphery of the retaining rings 6 is close to the inner wall of the borehole 15. When probing inside the borehole 15, the probe rod 5 and the camera can always be in the center of the borehole 15, which facilitates image processing and information extraction.

[0047] A pointer 9 is fixed to the outer periphery of the other end of the probe rod 5, and the pointer 9 is locked onto the probe rod 5 through a keyway.

[0048] A scale 8 is fitted around the outer periphery of the probe 5 near the pointer 9. The scale 8 is a detachable scale, which is fixed to the borehole 15 by an elastic wedge 7, so that the detachable scale 8 is fixed and cannot be rotated.

[0049] The probe 5, chuck 6, and pointer 9 are rigidly connected. The pointer 9, probe 5, chuck 6, and camera rotate synchronously, while the scale 8 remains stationary. This allows the pointer 9 to record the corresponding reading on the scale 8 during image capture, thus obtaining the borehole wall angle at the fracture location. This facilitates the analysis of the spatial distribution and orientation of the fracture from the image captured by the side view lens 2.

[0050] A handle 10 is fixedly connected to the rear end of the probe 5. By rotating the handle 10, the pointer 9, probe 5, chuck 6, and camera rotate synchronously. When the camera takes a picture, the reading of the separable dial 8 corresponding to the pointer 9 is recorded to obtain the orientation of the borehole wall in the picture.

[0051] The probe rod 5 and the lens bracket are secured together by clip 3 and tightened by nut 4. Figure 3 As shown, one end of the clip 3 has threads on both the inner and outer walls. The inner wall is threaded to the outer circumference of the probe rod 5, and the outer wall is threaded to the nut 4. The lens bracket is inserted into the other end of the clip 3. The side of the clip 3 has a through groove along the axial direction. The width of the through groove is the same as the diameter of the wire 11.

[0052] Furthermore, one end of the clip 3 is threaded to the end of the first hollow rod. The clip material is elastic, and the other end holds the lens bracket to stabilize the camera. The nut 4 can clamp the clip 3 to prevent the camera from shaking. The lens bracket is fixed to the front end of the probe rod 5 by the clip 3 and the nut 4, so that the camera is always in the center of the drill hole 15.

[0053] Example 4

[0054] Based on Example 3, the upper surface of the separable dial 8 is further marked with angles ranging from 0° to 360° to record the angle of the hole wall during photography. The lower surface of the separable dial 8 is fixedly connected to the elastic wedge 7, such as... Figure 2 As shown, the center of the elastic wedge 7 has a probe hole 14 for the probe rod 5 to pass through. The diameter of the probe hole 14 is larger than the diameter of the probe rod 5. The elastic wedge 7 is clamped to the borehole opening with an interference fit. Since the separable dial 8 is clamped to the borehole opening, the pointer 9 rotates with the probe rod 5 while the separable dial 8 remains fixed.

[0055] Example 5

[0056] Based on embodiment 4, LED lights are further installed on the lens bracket at positions below the foreground lens 1 and the side lens 2 to illuminate the lens and ensure the brightness inside the aperture when taking pictures. The LED lights are electrically connected to the controller 13.

[0057] Example 6

[0058] The display 12 is a handheld display. The handle 10 is connected to the end of the probe 5 away from the camera via a threaded connection. Based on the real-time images displayed on the display 12 of the foreground lens 1 and the side lens 2, the hole depth and hole wall orientation for taking pictures are determined.

[0059] The working principle of this drilling and probing device is as follows:

[0060] LED lights illuminate the camera to ensure brightness inside the hole when taking pictures. The controller sends a picture signal to the lens as needed. The camera is pushed along the drill hole 15 by the handle 10 and the probe 5. The hole depth and orientation captured by the side view lens 2 are determined according to the real-time foreground image received by the display 12. The handle 10 is rotated to align the side view lens 2 with the picture orientation, and a picture signal is sent to obtain the side view image and the corresponding foreground image. The pushing depth is recorded according to the corresponding scale on the probe, and the reading of the dial pointer 9 is recorded to indicate the hole depth and the orientation of the side view image.

[0061] The advantages of this drilling and exploration device are: simple structure, cost-saving, synchronous rotation of pointer, handle, probe rod, and lens. During exploration, the camera is inserted into the borehole through the probe rod. The position and angle of the side view lens are determined based on the foreground image, thereby obtaining foreground and side view images inside the borehole, reflecting the fracture characteristics of the borehole wall and the structural features of the rock mass, and providing a basis for evaluating the stability of the rock mass and the reinforcement method.
