Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering exploration technology, specifically to a geotechnical engineering surrounding rock fracture scanning detection device and its detection method. Background Technology

[0002] A fracture is a break in rock under stress, where the rock breaks without significant displacement along the fracture surface. Fractures are classified into two categories based on their formation: primary and secondary fractures. Primary fractures form during diagenesis, while secondary fractures are formed after rock formation by external forces. Based on the source of the force, they are further divided into non-tectonic and tectonic fractures. Primary fractures are formed by external geological processes, such as weathering, landslides, and collapses; they are often confined to the surface, small in scale, and irregularly distributed. Secondary fractures are formed by tectonic processes, are widely distributed and regularly occurring, extend long and deep, and can cut through different rock layers. Fractures have a significant impact on engineering construction, especially on the stability of tunnels and underground engineering projects.

[0003] Existing rock fissure detection devices are placed inside pre-drilled detection holes. Because the detection head is fixed in position, it can only detect the same depth within the hole. To detect different depths, the device needs to be manually moved, which is cumbersome. Therefore, there is an urgent need to solve this problem. Summary of the Invention

[0017] Another technical solution provided by the present invention: a detection method for a rock fissure scanning detection device for geotechnical engineering, using the aforementioned rock fissure scanning detection device for geotechnical engineering, specifically includes the following steps:

[0018] S1: Place the first cylinder into the detection hole to be detected;

[0019] S2: The first power mechanism provides power to the support assembly, causing the support assembly to open, and with the cooperation of the support assembly, the first cylinder is stably placed inside the detection hole;

[0020] S3: The second power mechanism provides power to the ejection component, which causes the camera to extend out of the square hole.

[0021] S4: Use a camera to take pictures of the cracks inside the detection hole and upload them.

[0022] S5: The moving mechanism operates, driving the camera to move and enabling detection at different depths of the detection hole.

[0023] This invention provides a rock fissure scanning and detection device and method for geotechnical engineering, which has the following advantages:

[0024] (1) The rock fissure scanning detection equipment for geotechnical engineering uses a moving mechanism to move the camera. As the camera moves, it can detect different positions of the detection hole. This allows for detection of different positions of the detection hole with a single installation, reducing the difficulty of operation for detection personnel and improving detection efficiency.

[0025] (2) This geotechnical engineering surrounding rock fissure scanning and detection equipment, through the setting of bearing seat, second threaded rod, third moving rod, sealing plate, slide groove, slider and first transmission rod, when the detection work is carried out, the second threaded rod rotates, which drives the third moving rod to extend outward, and then drives the camera to extend outward, so that the camera extends out of the square hole. After the camera extends out of the square hole, it is convenient to take pictures of the inner wall of the detection hole. The camera uploads the captured picture to the background for analysis to qualitatively describe the loosening range of the surrounding rock, thus realizing the detection of surrounding rock fissures. As the third moving rod moves outward, the sealing plate can be opened with the cooperation of the first transmission rod, slider and slide groove. With the opening of the sealing plate, it is convenient for the camera to extend out of the square hole. At the same time, the cooperation of slider and slide groove not only facilitates the movement of the camera, but also facilitates the stable opening of the sealing plate. After the detection work is completed, the second threaded rod rotates in the opposite direction, which can retract the camera into the first cylinder and close the sealing plate. This can protect the camera and help extend the service life of the camera.

[0026] (3) The geotechnical engineering surrounding rock fracture scanning detection equipment is equipped with a support frame, a first threaded rod, a movable frame, a handle, a first movable rod, a fixed seat, a rotating rod, an arc plate, a cone, and a second transmission rod. When in use, the handle is turned clockwise. With the cooperation of the first threaded rod, the movable frame can be moved, which in turn drives the first movable rod to slide inside the fixed seat. As the first movable rod moves, with the cooperation of the second transmission rod, the rotating rod can be rotated, so that the arc plate moves closer to the inner wall of the detection hole. At the same time, with the cooperation of the cone, the arc plate can be stably contacted with the inner wall of the detection hole. This achieves the support of the first cylinder, which is conducive to the stable placement of the first cylinder inside the detection hole, thus facilitating the subsequent detection work.

[0047] Please see Figures 1 to 16 A rock fissure scanning and detection device for geotechnical engineering includes a first cylinder 1. A support component 5 and a reset component 6 are provided on the outside of the first cylinder 1. The support component 5 is used to stably support the first cylinder 1 inside the detection hole. The reset component 6 corresponds to the support component 5. A first power mechanism 2 is provided on the left side of the first cylinder 1. The first power mechanism 2 is used to provide power for opening or closing the support component 5.

[0048] Specifically, the first power mechanism 2 includes a support frame 201, a first threaded rod 202, a movable frame 203, a handle 204, and a first movable rod 205. The support frame 201 is fixedly connected to the left side of the first cylinder 1. The first threaded rod 202 is rotatably connected inside the support frame 201. The handle 204 is fixedly connected to the left end of the first threaded rod 202. The movable frame 203 is threadedly connected to the circumferential surface of the first threaded rod 202. The first movable rod 205 is fixedly connected to the right sides of both ends of the movable frame 203. The support assembly 5 includes a fixed seat 501, a rotating rod 502, an arc plate 503, a conical spike 504, and a second transmission rod 505. The fixed seat 501 is fixedly connected to the circumferential surface of the first cylinder 1. The first movable rod 205 passes through the fixed seat 501 and is slidably connected to the fixed seat 501. The upper end of the fixed seat 501 is rotatably connected to the first moving rod 205. A rotating rod 502 is connected, and one end of the rotating rod 502 away from the fixed base 501 is fixedly connected to the arc plate 503; the lower end of the rotating rod 502 is rotatably connected to the second transmission rod 505, and the second transmission rod 505 is rotatably connected to the first moving rod 205; the reset assembly 6 includes a second cylinder 601, a second moving rod 602, a first baffle 603, a second baffle 604, and a first spring 605. The second cylinder 601 is fixedly connected to the circumferential surface of the first cylinder 1, and the second moving rod 602 is slidably connected inside the second cylinder 601. The upper end of the second moving rod 602 is arc-shaped, and the second baffle 604 is fixedly connected to the circumferential surface of the second moving rod 602. The first baffle 603 is fixedly connected to the circumferential surface of the second cylinder 601, and the first spring 605 is fixedly connected between the first baffle 603 and the second baffle 604.

[0049] In use, the first cylinder 1 is placed inside the detection hole of the surrounding rock. Then, the handle 204 is turned clockwise. With the cooperation of the first threaded rod 202, the moving frame 203 can be moved, which in turn causes the first moving rod 205 to slide inside the fixed seat 501. As the first moving rod 205 moves, with the cooperation of the second transmission rod 505, the rotating rod 502 can be rotated, causing the arc plate 503 to move closer to the inner wall of the detection hole. At the same time, with the cooperation of the cone 504, the arc plate 503 can be stably contacted with the inner wall of the detection hole. This achieves support for the first cylinder 1, which is beneficial for the first cylinder 1 to be stably placed in the detection hole. The inside is made easier for subsequent detection work; after the detection work is completed, the handle 204 is reversed, which can drive the arc plate 503 to move closer to the first cylinder 1. As the arc plate 503 moves, after the arc plate 503 contacts the second moving rod 602, it will squeeze the second moving rod 602 to move into the second cylinder 601. Then, with the cooperation of the first baffle 603 and the second baffle 604, the first spring 605 can be compressed. The compressed first spring 605 is conducive to the second moving rod 602 to reset, so that the arc plate 503 can move closer to the inner wall of the detection hole, which is conducive to the contact between the arc plate 503 and the inner wall of the detection hole.

[0050] A buffer assembly 7 and a cone head 8 are provided on the right side of the first cylinder 1. The first cylinder 1 is connected to the cone head 8 through the buffer assembly 7. Specifically, the buffer assembly 7 includes a damper 701 and a second spring 702. The damper 701 is fixedly connected to the right end of the first cylinder 1 and is fixedly connected to the cone head 8.

One end of the second spring 702 is fixedly connected to the cone head 8, and the other end of the second spring 702 is fixedly connected to the first cylinder 1.

[0051] In use, during the placement of the first cylinder 1, the cone 8 facilitates the entry of the first cylinder 1 into the detection hole. When the cone 8 collides with the detection hole during its entry, the damper 701 and the second spring 702 work together to buffer the impact, preventing the cone 8 from vibrating violently and thus improving the protection of the equipment inside the first cylinder 1.

[0052] The first cylinder 1 has four square holes 3 on its circumferential surface, arranged in a circular array. The first cylinder 1 has four sets of sealing components 4, which correspond to the square holes 3. The first cylinder 1 also has a second power mechanism 9 and a moving mechanism 10. The moving mechanism 10 has a push-out component 11 and a camera 12 on its left side. The moving mechanism 10 is connected to the camera 12 through the push-out component 11.

A second gear 905 is fixedly connected to the circumferential surface of the transmission shaft 904, and the second gear 905 meshes with the first gear 903. A rotating cylinder 908 is rotatably connected inside the movable disk 1004. The transmission shaft 904 is located inside the rotating cylinder 908 and is slidably connected to the rotating cylinder 908. There are four transmission shafts 904 and four rotating cylinders 908, which correspond to the ejection assembly 11. A first bevel gear 906 is fixedly connected to the circumferential surface of the rotating cylinder 908, and a second bevel gear 907 meshes with the side end of the first bevel gear 906. The ejection assembly 11 includes a bearing seat 1101, a second threaded rod 1102, and a third movable... The moving disk 1004 has a rod 1103, a limiting strip 1104, and a limiting groove 1105. A bearing seat 1101 and a limiting groove 1105 are fixedly connected to the left side of the moving disk 1004. A second threaded rod 1102 is rotatably connected inside the bearing seat 1101. The second threaded rod 1102 is fixedly connected to the second bevel gear 907. A third moving rod 1103 is threadedly connected to the circumferential surface of the second threaded rod 1102. The left side of the third moving rod 1103 is fixedly connected to the camera 12. A limiting strip 1104 is slidably connected inside the limiting groove 1105. The limiting strip 1104 is fixedly connected to the third moving rod 1103. The sealing assembly 4 includes a sealing plate 401, a sliding groove 402, a slider 403, and a first transmission rod 404. A first cylinder 1 is slidably connected inside the first cylinder 1. A sealing plate 401 is provided, which corresponds to the square hole 3. A sliding groove 402 is fixedly connected to the inner side of the sealing plate 401. A slider 403 is slidably connected inside the sliding groove 402. A first transmission rod 404 is rotatably connected to one end of the slider 403 away from the bottom of the sliding groove 402. The first transmission rod 404 is rotatably connected to the third moving rod 1103. The moving mechanism 10 includes a second motor 1001, a second fixed plate 1002, a lead screw 1003, and a moving disk 1004. A second fixed plate 1002 is fixedly connected inside the first cylinder 1.

[0054] In use, after the first cylinder 1 is stably positioned inside the detection hole, the first motor 902 rotates forward. At this time, with the cooperation of the first gear 903 and the second gear 905, it can drive the four transmission shafts 904 to rotate simultaneously, thereby driving the rotating cylinder 908 to rotate. As the rotating cylinder 908 rotates, with the cooperation of the first bevel gear 906 and the second bevel gear 907, it can drive the second threaded rod 1102 to rotate. The rotation of the second threaded rod 1102 drives the third moving rod 1103 to move outward. At the same time, with the cooperation of the limiting strip 1104 and the limiting groove 1105... The combination of these mechanisms makes the movement of the third moving rod 1103 more stable. When the third moving rod 1103 moves outward, it can drive the camera 12 to move outward as well. Simultaneously, the outward movement of the third moving rod 1103, in conjunction with the first transmission rod 404, the slider 403, and the sliding groove 402, can drive the sealing plate 401 to open. With the sealing plate 401 open, the camera 12 can easily extend out of the square hole 3. After the camera 12 extends out of the square hole 3, it can easily capture images of the inner wall of the detection hole. The camera 12 then uploads the captured images to the backend for analysis to determine... The description of the loosening range of the surrounding rock enables the detection of rock fissures. After the camera 12 has detected a location inside the detection hole, the second motor 1001 operates, and with the assistance of the lead screw 1003, it drives the moving disk 1004 to move. As the moving disk 1004 moves, different locations within the detection hole can be detected, allowing for detection of different locations within the detection hole with a single installation. This reduces the operational difficulty for detection personnel and improves detection efficiency. Simultaneously, because the sliding groove 402 is oriented parallel to the axial direction of the first cylinder 1, this allows for... When the moving plate 1004 moves, it also drives the slider 403 to slide inside the groove 402, so that the sealing plate 401 is stably in the open state, which facilitates the camera 12 to perform surrounding rock fissure detection. After the detection is completed, the first motor 902 works in reverse, which drives the third moving rod 1103 to move inward, thereby driving the camera 12 to be stored inside the first cylinder 1. After the camera 12 enters the first cylinder 1, the sealing plate 401 is also closed, which can protect the camera 12 and help extend the service life of the camera 12.
