Description
Technical Field
[0001] This utility model relates to the field of concrete pipe appearance inspection technology, specifically to an image acquisition device for large-diameter concrete pipes. Background Technology
[0002] After casting, large-diameter concrete pipes (including reinforced concrete pipes, prestressed steel cylinder concrete pipes, etc.) often exhibit quality defects such as surface porosity and watermarks. Currently, the common method is to determine the presence of defects by visual inspection or manual image acquisition equipment. However, this method is insufficient for accurately assessing the overall quality of the large-diameter concrete pipe's appearance. When manually using image acquisition equipment to capture images of large-diameter concrete pipes, maintaining a consistent acquisition distance and angle is difficult. Furthermore, large-area acquisition of large-diameter concrete pipes results in significant errors, while reducing the acquisition area to a smaller area increases the difficulty. Multiple acquisitions at multiple angles not only make it harder to maintain a consistent acquisition distance but also lead to discontinuous image acquisition. Therefore, there is an urgent need for an image acquisition device specifically designed for large-diameter concrete pipes to address these issues. Utility Model Content
[0003] To address the challenges of maintaining consistent acquisition distance and angle when manually acquiring images of large-diameter concrete pipes using image acquisition equipment, and the significant errors that arise when acquiring large-area images of large-diameter concrete pipes while reducing the acquisition area to smaller areas further complicates the process, and the need for multiple angles and repeated acquisitions not only makes it difficult to maintain a consistent acquisition distance but also leads to discontinuous image acquisition, this invention provides an image acquisition device for large-diameter concrete pipes. This device features a simple structure, easy installation, and a high-definition panoramic camera that rotates at a uniform speed. When acquiring images of a specific height range on the inner or outer wall of a large-diameter concrete pipe, the entire acquisition process remains continuous, maintaining consistency in acquisition height, distance, and angle. Furthermore, the acquisition height of the image acquisition device itself is adjustable.
[0004] This invention provides an image acquisition device for large-diameter concrete pipes, comprising a circular track, a support frame, and a high-definition panoramic camera. The circular track is mounted on the inner or outer wall of the large-diameter concrete pipe. The support frame is rotatably mounted on the circular track and rotates circumferentially within the track. The high-definition panoramic camera is mounted on the support frame via a telescopic mechanism, with its lens facing the inner or outer wall of the large-diameter concrete pipe. The support frame rotates at a constant speed on the circular track, thereby causing the telescopic mechanism and the high-definition panoramic camera to rotate at a constant speed relative to the circular track, i.e., the high-definition panoramic camera rotates at a constant speed relative to the outer wall of the large-diameter concrete pipe. The uniformly rotating high-definition panoramic camera acquires images of a certain height range of the outer wall of the large-diameter concrete pipe. The entire acquisition process is continuous, and the acquisition distance and acquisition angle remain consistent.
[0005] Furthermore, the support frame includes an L-shaped connecting frame and a main frame. The crossbar of the L-shaped connecting frame is fixedly connected to the top of the main frame. The high-definition panoramic camera is mounted on the crossbar of the L-shaped connecting frame and located above the main frame via a telescopic mechanism. The vertical bar of the L-shaped connecting frame is rotatably mounted in the first annular groove at the top of the circular track. A rotating wheel is rotatably mounted on the outer side of the lower part of the main frame. The rotating wheel is located in the second annular groove at the bottom of the circular track and rotates circumferentially. The rotating wheel rotates at a constant speed in the second annular groove, thereby driving the vertical bar to rotate at a constant speed in the first annular groove. The entire support frame rotates at a constant speed relative to the circular track, ultimately achieving uniform rotation of the high-definition panoramic camera relative to the circular track. When the high-definition panoramic camera rotates at a constant speed to collect data at different heights of a large-diameter concrete pipe, the acquisition distance and acquisition angle of the high-definition panoramic camera remain consistent.
[0006] Furthermore, the vertical rod of the L-shaped connecting frame is provided with a first groove, and the groove wall of the first annular groove is provided with an annular groove. A steel ball is movably disposed between the first groove and the annular groove. The steel ball rotates relative to the first groove and the annular groove, reducing the frictional force of the vertical rod of the L-shaped connecting frame rotating in the second annular groove. The first groove and the annular groove also limit the steel ball, preventing it from dislodging from the groove.
[0007] Furthermore, an electrically connected battery and wireless control module are disposed on the inner side of the main frame body, and a motor is disposed on the outer side of the lower part of the main frame body. The motor is electrically connected to both the battery and the wireless control module. The output shaft of the motor is fixedly connected to the main gear, and a driven gear meshing with the main gear is disposed on the axle of the rotating wheel. The wireless control module controls the starting and stopping of the motor, and the battery supplies power to the motor and the wireless control module. When the motor starts, it drives the main gear to rotate, which in turn drives the driven gear meshing with the main gear to rotate, thus rotating the rotating wheel.
[0008] Furthermore, the annular track includes two semi-circular tracks, which are locked to the outer wall of the large-diameter concrete pipe by a first fixing bolt. The upper part of the two semi-circular tracks forms a first annular groove located on one side of the outer wall of the large-diameter concrete pipe. The lower part of the two semi-circular tracks is provided with a first annular block, on which a second annular groove is provided with the opening of the second annular groove facing the rotating wheel. A first anti-slip pad is provided between the two semi-circular tracks and the outer wall of the large-diameter concrete pipe. A first reinforcing plate is provided between the upper and lower parts of each semi-circular track.
[0009] Furthermore, the annular track includes an arc-shaped track, the two ends of which are locked by second fixing bolts and the arc-shaped track is attached to the inner wall of the large-diameter concrete pipe. The upper part of the arc-shaped track forms a first annular groove, which is located on one side of the inner wall of the large-diameter concrete pipe. A second annular block is provided on one side of the lower part of the annular track. The second annular block is provided with a second annular groove, and the groove opening faces the rotating wheel. A second anti-slip pad is provided between the arc-shaped track and the inner wall of the large-diameter concrete pipe. A second reinforcing plate is provided between the upper and lower parts of the arc-shaped track.
[0010] Furthermore, the telescopic mechanism includes a first telescopic part and a second telescopic part. The first telescopic part includes a first square frame and a second square frame that are slidably connected. The second square frame is fitted inside the first square frame and slides left and right relative to the first square frame. The first square frame is fixedly connected to the crossbar of the L-shaped connecting frame and is located above the main frame. The second telescopic part includes a first annular rod and a second annular rod that are slidably connected. The second annular rod is fitted inside the first annular rod and slides up and down relative to the first annular rod. The first annular rod is fixedly connected to the side of the second square frame away from the first square frame. The high-definition panoramic camera is rotatably mounted on the top of the second annular rod. The second square frame slides left and right relative to the first square frame and is fixed, enabling the high-definition panoramic camera to collect images of the outer wall of the large-diameter concrete pipe from different distances. The second annular rod slides up and down relative to the first annular rod and is fixed, enabling the high-definition panoramic camera to collect images of the outer wall of the large-diameter concrete pipe from different heights. At this time, the position of the high-definition panoramic camera remains fixed, and the high-definition panoramic camera remains horizontal.
[0011] Furthermore, the first square frame is provided with a screw hole, and a fastening knob is movably mounted on the screw hole. The bottom of the fastening knob passes through the screw hole and abuts against the second square frame. When the fastening knob is manually tightened, so that the bottom of the fastening knob passes through the screw hole and abuts against the second square frame, the second square frame cannot slide left or right. When the fastening knob is manually loosened, so that the bottom of the fastening knob leaves the second square frame, the second square frame can slide left or right.
[0012] Furthermore, the length of the first annular rod is less than the length of the second annular rod. Both the first and second annular rods are multi-segmented. The first annular rod has multiple first fixing holes evenly distributed on it, and the second annular rod has multiple second fixing holes and fixing blocks evenly distributed on it. The fixing blocks are located inside the second annular rod and have fixing grooves that correspond to the second fixing holes. Limiting rods are slidably disposed within the first and second fixing holes. One end of the limiting rod extends out of the first fixing hole, and the other end passes through the first fixing hole into the fixing groove and is fixedly connected to the groove wall by a spring. When a person manually presses one end of the limiting rod into the second fixing hole, the limiting rod slides within the first and second fixing holes, and the spring is compressed. The second annular rod can then slide up and down relative to the first annular rod. When the person releases the limiting rod, the spring returns to its extended state, and the spring force causes the limiting rod to slide within the first and second fixing holes. At this point, one end of the limiting rod re-exits the first fixing hole, and the second annular rod can no longer slide up and down relative to the first annular rod.
[0013] Furthermore, a omnidirectional ball is provided at the top of the second annular rod, and a support base is provided on the main ball of the omnidirectional ball. The high-definition panoramic camera is fixedly connected to the support groove of the support base. After the main ball on the omnidirectional ball rotates, it will drive the support base and the high-definition panoramic camera to rotate. The high-definition panoramic camera can rotate as needed to achieve its own non-directional fine adjustment.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This utility model relates to an image acquisition device for large-diameter concrete pipes. It features a simple structure and easy installation. A high-definition panoramic camera rotating at a constant speed captures images of a specific height range on the inner or outer wall of the large-diameter concrete pipe. The entire acquisition process remains continuous, with consistent acquisition height, distance, and angle. Furthermore, the acquisition height of the image acquisition device itself is adjustable. The resulting data is more accurate, providing a quantitative technical means for evaluating the forming quality of large-diameter concrete pipes and accelerating the identification of any defects in their appearance.

[0026] 5. Large-diameter concrete pipes. Detailed Implementation
[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] like Figures 1-4 As shown in Embodiment 1, an image acquisition device for a large-diameter concrete pipe includes a ring track 3, a support frame 2, and a high-definition panoramic camera 1. The ring track 3 is set on the outer wall of the large-diameter concrete pipe 5. The support frame 2 is rotatably set on the ring track 3 and rotates circumferentially on the ring track 3. The high-definition panoramic camera 1 is set on the support frame 2 through a telescopic mechanism 4, and the lens of the high-definition panoramic camera 1 faces the outer wall of the large-diameter concrete pipe 5.
[0029] When the image acquisition device of this embodiment acquires images of a certain height range of the outer wall of the large-diameter concrete pipe 5, the annular track 3 is installed at a certain position on the outer wall of the large-diameter concrete pipe 5 as required. The support frame 2 rotates at a constant speed on the annular track 3, thereby driving the telescopic mechanism 4 and the high-definition panoramic camera 1 to rotate at a constant speed relative to the annular track 3. That is, the high-definition panoramic camera 1 rotates at a constant speed relative to the outer wall of the large-diameter concrete pipe 5. The high-definition panoramic camera 1, which rotates at a constant speed, acquires images of a certain height range of the outer wall of the large-diameter concrete pipe 5. The entire acquisition process is continuous, and the acquisition distance and acquisition angle remain consistent.
[0030] After the acquisition of the aforementioned height range is completed, when it is necessary to acquire data for another height range, the circular track 3 is installed at another position on the outer wall of the large-diameter concrete pipe 5, and the high-definition panoramic camera 1, rotating at a uniform speed, acquires data for another height range on the outer wall of the large-diameter concrete pipe 5. The entire acquisition process remains continuous, and the acquisition distance and angle remain consistent. The acquisition height of the image acquisition device can be adjusted when acquiring data from the outer wall of the large-diameter concrete pipe 5, and the acquisition range of the image acquisition device can cover the entire outer surface of the large-diameter concrete pipe 5.
[0031] The image acquisition device for large-diameter concrete pipes in this embodiment has a simple structure and is easy to install. When the high-definition panoramic camera 1, rotating at a constant speed, acquires data within a certain height range of the outer wall of the large-diameter concrete pipe 5, the entire acquisition process remains continuous, and the acquisition height, distance, and angle remain consistent. Furthermore, the acquisition height of the image acquisition device itself can be adjusted. The data ultimately acquired by the image acquisition device for large-diameter concrete pipes in this embodiment is more accurate, thus providing a quantitative technical means for evaluating the forming quality of the large-diameter concrete pipe 9 and accelerating the confirmation of whether there are defects in the appearance of the large-diameter concrete pipe 5.
[0032] In one possible implementation, the support frame 2 includes an L-shaped connecting frame 21 and a main frame 22. The crossbar of the L-shaped connecting frame 21 is fixedly connected to the top of the main frame 22. The crossbar of the L-shaped connecting frame 21 and the top of the main frame 22 can be fixedly connected by welding or integral molding. The high-definition panoramic camera 1 is mounted on the crossbar of the L-shaped connecting frame 21 and located above the main frame 22 via a telescopic mechanism 4. The vertical rod of the L-shaped connecting frame 21 is rotatably mounted in the first annular groove 31 at the upper part of the annular track 3. A rotating wheel 23 is rotatably mounted on the outer side of the lower part of the main frame 22. The rotating wheel 23 is located in the second annular groove 32 at the lower part of the annular track 3 and rotates circumferentially. The rotating wheel 23 rotates at a constant speed in the second annular groove 32, thereby driving the vertical rod to rotate at a constant speed in the first annular groove 31. The support frame 2 as a whole rotates at a constant speed relative to the annular track 3, ultimately achieving uniform rotation of the high-definition panoramic camera 1 relative to the annular track 3. When the high-definition panoramic camera 1 rotates at a constant speed to collect data at different heights of the large-diameter concrete pipe 5, the acquisition distance and acquisition angle of the high-definition panoramic camera 1 remain consistent.
[0033] When the support frame 2 rotates as a whole, because the telescopic mechanism 4 and the high-definition panoramic camera 1 are located on the side of the support frame 2 away from the annular track 3, the groove wall of the first annular groove 31 provides support for the support frame 2, ensuring that the support frame 2 rotates normally. The groove wall of the first annular groove 31 limits and supports the support frame 2, the telescopic mechanism 4, and the high-definition panoramic camera 1, ensuring that the support frame 2, the telescopic mechanism 4, and the high-definition panoramic camera 1 rotate normally and do not tip over. Among them, the L-shaped connecting frame 21 and the main frame 22 are made of aluminum alloy; the rotating wheel 23 is made of rubber. The support frame 2 is easy to install and disassemble, and can rotate at a uniform speed within the annular track 3.
[0034] In one possible implementation, the vertical rod of the L-shaped connecting frame 21 is provided with a first groove, and the groove wall of the first annular groove 31 is provided with an annular groove. A steel ball 24 is movably disposed between the first groove and the annular groove. The rotating wheel 23 rotates at a constant speed in the second annular groove 32, thereby driving the vertical rod of the L-shaped connecting frame 21 to rotate at a constant speed in the first annular groove 31, and the support frame 2 as a whole rotates at a constant speed relative to the annular track 3. The steel ball 24 is movably disposed between the first groove and the annular groove. The steel ball 24 rotates relative to the first groove and the annular groove. The steel ball 24 reduces the frictional force of the vertical rod of the L-shaped connecting frame 21 rotating in the second annular groove 32, and the first groove and the annular groove limit the steel ball 24 to prevent the steel ball 24 from dislodging from the groove.
[0035] In one possible implementation, a battery 25 and a wireless control module 26 are electrically connected to each other on the inner side of the main frame 22. A motor 27 is located on the outer side of the lower part of the main frame 22. The motor 27 is electrically connected to both the battery 25 and the wireless control module 26. The output shaft of the motor 27 is fixedly connected to the main gear. A driven gear that meshes with the main gear is mounted on the axle of the rotating wheel 23. The function and structure of the wireless control module 26 are existing technologies and will not be described in detail here. The wireless control module 26 controls the starting and stopping of the motor 27, and the battery 25 supplies power to the motor 27 and the wireless control module 26. When the motor 27 starts, it drives the main gear to rotate, which in turn drives the driven gear meshing with the main gear to rotate, thus rotating the rotating wheel 23.
[0036] The further rotating wheel 23 is provided in two, with the two rotating wheels 23 arranged side by side; one of the rotating wheels 23 is provided with a driven gear that meshes with the main gear.
[0037] In one possible implementation, the annular track 3 includes two semi-circular tracks 33, which are locked to the outer wall of the large-diameter concrete pipe 5 by a first fixing bolt. The upper part of each semi-circular track 33 forms a first annular groove 31 located on one side of the outer wall of the large-diameter concrete pipe 5. The lower part of each semi-circular track 33 is provided with a first annular block, on which a second annular groove 32 is provided, with the opening of the second annular groove 32 facing the rotating wheel 23. A first anti-slip pad 34 is provided between the two semi-circular tracks 33 and the outer wall of the large-diameter concrete pipe 5. A first reinforcing plate 35 is provided between the upper and lower parts of each semi-circular track 33. When the annular track 3 needs to be installed on the outer wall of the large-diameter concrete pipe 5, the annular track 3 includes two semi-circular tracks 33. According to the location to be sampled from the large-diameter concrete pipe 5, the two semi-circular tracks 33 are locked to the outer wall of the large-diameter concrete pipe 5 by the first fixing bolt. The first anti-slip pad layer 34 ensures that the two semi-circular tracks 33 are further stabilized on the outer wall of the large-diameter concrete pipe 5. Furthermore, one first anti-slip pad layer 34 is provided at 90° intervals, for a total of four. The purpose of providing the first reinforcing plate 35 is to enhance the overall structural strength of the semi-circular tracks 33. Furthermore, one first reinforcing plate 35 is provided at 45° intervals, for a total of eight.
[0038] In one possible implementation, the telescopic mechanism 4 includes a first telescopic part and a second telescopic part. The first telescopic part includes a first square frame 41 and a second square frame 42 that are slidably connected. The second square frame 42 is fitted inside the first square frame 41 and slides left and right relative to the first square frame 41. The first square frame 41 is fixedly connected to the crossbar of the L-shaped connecting frame 21 and is located above the main frame 22. The first square frame 41 is welded to the crossbar of the L-shaped connecting frame 21. The second telescopic part includes a first annular rod 44 and a second annular rod 45 that are slidably connected. The second annular rod 45 is fitted inside the first annular rod 44 and slides up and down relative to the first annular rod 44. The first annular rod 44 is fixedly connected to the side of the second square frame 42 away from the first square frame 41 by connecting bolts. The high-definition panoramic camera 1 is rotatably mounted on the top of the second annular rod 45. The second square frame 42 slides left and right relative to the first square frame 41 and is fixed, enabling the high-definition panoramic camera 1 to capture images of the outer wall of the large-diameter concrete pipe 5 from different distances. The second annular rod 45 slides up and down relative to the first annular rod 44 and is fixed, enabling the high-definition panoramic camera 1 to capture images of the outer wall of the large-diameter concrete pipe from different heights. At this time, the position of the high-definition panoramic camera 1 remains fixed and horizontal. It is worth noting that the overall height of the image acquisition device on the large-diameter concrete pipe 5 and the height of the high-definition panoramic camera 1 on the second annular rod 45 are adjustable, further expanding the height range of the high-definition panoramic camera 1. When it is necessary to adjust the acquisition distance and height of the high-definition panoramic camera 1, the positions of the second square frame 42 and the second annular rod 45 are adjusted to ultimately meet the requirements of the high-definition panoramic camera 1. The first square frame 41, the second square frame 42, the first annular rod 44, and the second annular rod 45 are made of aluminum alloy.
[0039] In one possible implementation, the first square frame 41 is provided with a screw hole, and a fastening knob 43 is movably disposed on the screw hole. The fastening knob 43 is threadedly connected to the internal thread in the screw hole via an external thread on its bottom. The bottom of the fastening knob 43 passes through the screw hole and abuts against the second square frame 42. When the fastening knob 43 is manually tightened, so that the bottom of the fastening knob 43 passes through the screw hole and abuts against the second square frame 42, the second square frame 42 cannot slide left or right. When the fastening knob 43 is manually loosened, so that the bottom of the fastening knob 43 leaves the second square frame 42, the second square frame 42 can slide left or right.
[0040] In one possible implementation, the length of the first annular rod 44 is less than the length of the second annular rod 45, ensuring that the second annular rod 45 can be manually adjusted. Both the first annular rod 44 and the second annular rod 45 are multi-segmented. The first annular rod 44 is provided with a plurality of first fixing holes, which are located at multiple rod segments of the first annular rod 44. The second annular rod 45 is provided with a plurality of second fixing holes and fixing blocks, which are located at multiple rod segments of the second annular rod 45. The fixing blocks are located inside the second annular rod 45 and are provided with fixing grooves that correspond to the second fixing holes. Limiting rods 46 are slidably disposed in the first fixing holes and the second fixing holes. One end of the limiting rod 46 extends out of the first fixing hole, and the other end of the limiting rod 46 passes through the first fixing hole into the fixing groove and is fixedly connected to the groove wall of the fixing groove by a spring 47. When a person manually presses one end of the limiting rod 46 into the second fixing hole, the limiting rod 46 slides within the first and second fixing holes, and the spring 47 is compressed. The second annular rod 45 can then slide up and down relative to the first annular rod 44. When the person releases the limiting rod 46, the spring 47 returns to its extended state. The elastic force of the spring 47 causes the limiting rod 46 to slide within the first and second fixing holes. At this point, one end of the limiting rod 46 re-exits the first fixing hole, and the second annular rod 45 can no longer slide up and down relative to the first annular rod 44. Furthermore, the first annular rod 44 and the second annular rod 45 are designed as multi-segment structures. When multiple limiting rods 46 simultaneously restrict the position of the second annular rod 45, preventing it from sliding, the first annular rod 44 and the second annular rod 45 become more stable.
[0041] In one possible implementation, a omnidirectional ball 48 is provided at the top of the second annular rod 45, and a support base 49 is provided on the main ball of the omnidirectional ball 48. The high-definition panoramic camera 1 is fixedly connected to the support groove of the support base 49. The structure of the omnidirectional ball 48 and the rotation method of the main ball on the omnidirectional ball 48 are existing technologies and will not be described in detail here. Generally, the omnidirectional ball 48 includes a seat with an arc-shaped cavity and a main ball. Several auxiliary balls are provided in the arc-shaped cavity of the seat, and these auxiliary balls can rotate. The bottom of the main ball abuts against the auxiliary balls, and the top of the main ball extends out of the cavity. The omnidirectional ball 48 and the support base 49 enable the adjustment of the acquisition angle of the high-definition panoramic camera 1. After the main ball on the omnidirectional ball 48 rotates, it will drive the support base 49 and the high-definition panoramic camera 1 to rotate. The high-definition panoramic camera 1 can rotate as needed to achieve its own non-directional fine adjustment. The lens of the high-definition panoramic camera 1 is always facing the outer wall of the large-diameter concrete pipe, thus ensuring that the high-definition panoramic camera 1 maintains a consistent acquisition angle for the five large-diameter concrete pipes. Moreover, the high-definition panoramic camera 1 can acquire continuous high-definition panoramic photos, which is convenient for subsequent confirmation of the molding quality of the five large-diameter concrete pipes. The support base 49 is made of aluminum alloy.
[0042] In this embodiment, during the image acquisition process, the rotating wheel 23 rotates at a constant speed within the second annular groove 32, thereby driving the vertical rod of the L-shaped connecting frame 21 to rotate at a constant speed within the first annular groove 31. The support frame 2 rotates at a constant speed relative to the annular track 3. The first square frame 41, the second square frame 42, the first annular rod 44, the second annular rod 45, and the high-definition panoramic camera 1 rotate at a constant speed relative to the annular track 3. The positions of the first square frame 41 and the second square frame 42 are fixed, the positions of the first annular rod 44 and the second annular rod 45 are fixed, and the positions of the high-definition panoramic camera 1 and the support base 49 on the gimbal 48 are fixed. Therefore, when the high-definition panoramic camera 1 rotates at a constant speed, its acquisition height, acquisition angle, and acquisition distance remain consistent, and the acquisition remains continuous.
[0043] like Figure 5 As shown in Embodiment 2, unlike Embodiment 1, the annular track 3 is set on the inner wall of the large-diameter concrete pipe 5, and the lens of the high-definition panoramic camera 1 faces the inner wall of the large-diameter concrete pipe 5. Specifically, the annular track 3 includes an arc-shaped track 36, the two ends of which are locked by second fixing bolts and the arc-shaped track 36 is attached to the inner wall of the large-diameter concrete pipe 5. The two ends of the arc-shaped track 36 are respectively provided with a first inclined surface and a second inclined surface, and the first inclined surface and the second inclined surface are attached to each other. The upper part of the arc-shaped track 36 forms a first annular groove 31, and the first annular groove 31 is located on one side of the inner wall of the large-diameter concrete pipe 5. The lower part of the annular track 3 has a second annular block on one side, and the second annular block is provided with a second annular groove 32, and the groove opening of the second annular groove 32 faces the rotating wheel 23. A second anti-slip pad layer 37 is provided between the arc-shaped track 36 and the inner wall of the large-diameter concrete pipe 5, and a second reinforcing plate 38 is provided between the upper and lower parts of the arc-shaped track 36. When the annular track 3 needs to be installed on the inner wall of the large-diameter concrete pipe 5, the annular track 3 includes an arc-shaped track 36. Based on the location to be sampled on the large-diameter concrete pipe 5, both ends of the arc-shaped track 36 are locked with second fixing bolts, and the arc-shaped track 36 is attached to the inner wall of the large-diameter concrete pipe 5. The second anti-slip pad layer 37 ensures that the arc-shaped track 36 is further stabilized on the inner wall of the large-diameter concrete pipe 5. Furthermore, four second anti-slip pad layers 37 are provided at 90° intervals. The purpose of providing the second reinforcing plate 38 is to strengthen the overall structural strength of the arc-shaped track 36. Furthermore, eight second reinforcing plates 38 are provided at 45° intervals. The annular track 3 is entirely made of polyethylene; the first anti-slip pad layer 34 and the second anti-slip pad layer 37 are made of silicone; and the first reinforcing plate 35 and the second reinforcing plate 38 are made of polyethylene.
[0044] The image acquisition device for large-diameter concrete pipes in this embodiment has a simple structure and is easy to install. When the high-definition panoramic camera 1, rotating at a constant speed, acquires images of a certain height range of the inner wall of the large-diameter concrete pipe 5, the entire acquisition process remains continuous, and the acquisition height, distance, and angle remain consistent. Furthermore, the acquisition height of the image acquisition device itself can be adjusted. This facilitates subsequent confirmation of the forming quality of the large-diameter concrete pipe 5 and accelerates the identification of any defects in its appearance. It is worth noting that the image acquisition device can acquire images of either the inner or outer wall of the large-diameter concrete pipe 5; alternatively, two sets can be configured to simultaneously acquire images of both the inner and outer walls of the large-diameter concrete pipe 5.
