Technical Field
[0001] This utility model relates to the field of pipeline inspection technology, specifically a pipeline defect detection device. Background Technology
[0002] With the rapid pace of urbanization and the substantial increase in urban population, the number and length of urban drainage and sewage pipes have surged, highlighting environmental problems caused by pipe defects. For example, structural defects such as pipe ruptures and misalignments can cause liquids to leak out of pipes, polluting the surrounding environment. Furthermore, prolonged erosion and leaching can lead to ground subsidence around the pipes, posing significant safety hazards. Periodic pipe inspections have become essential.
[0003] For example, in a pipeline defect detection device with publication number CN210978973U, a drive component is installed on any of the eight wheels, a camera is used to capture the internal condition of the pipeline, and the pipeline defect is detected by viewing the internal condition captured by the camera. A sliding component is provided between the machine body and each wheel.
[0004] The wheels around the aforementioned pipeline defect detection device contact the inner wall of the pipeline, placing the camera on the device in the center. Since the diameter of pipelines varies for different purposes, the position of the camera remains unchanged. However, when the diameter of the pipeline is too large, the image captured by the camera may be unclear, affecting the later location of defects. Utility Model Content
[0005] The purpose of this invention is to provide a pipeline defect detection device to solve the problem mentioned in the background art that the position of the camera in the current market remains unchanged, and when the pipeline diameter is too large, the image captured by the camera may be unclear, affecting the later personnel's ability to find the defect point.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipeline defect detection device, comprising a support rod, a mounting base, and a central camera. The top of the support rod is fitted with a mounting base, and the central camera is mounted on the mounting base. The top of the support rod is rotatably connected to a fixed bracket at equal angles, and the fixed bracket is provided with an adjustment mechanism. A side camera is mounted on the adjustment mechanism, and the adjustment mechanism is used to control the distance between the side camera and the inner wall of the pipeline.
[0007] Preferably, a wheel is rotatably connected to the end of the fixed bracket via a shaft, and a motor is installed at one end of the fixed bracket, with the output end of the motor fixed to the wheel shaft.
[0008] Preferably, the support rod is threaded with a swivel ring, and the upper end of the swivel ring is rotatably connected to a fixed ring, which passes through the support rod.
[0009] Preferably, the adjustment mechanism includes a slide groove, a sleeve, and a fixing block. The sleeve is installed at an equal angle on the upper fixing ring, and the fixing block is installed at the end of the sleeve. The fixing bracket has a slide groove inside, and the inside of the slide groove is slidably connected to the fixing block.
[0010] Preferably, a side camera is installed at the end of the fixing block, and the sliding groove is arranged parallel to the fixing bracket.
[0011] Preferably, the lower fixing ring is rotatably connected to a support leg, and the other end of the support leg is rotatably connected to a fixing bracket.
[0012] Preferably, a mounting base is installed at the top of the support rod, and lighting lamps are installed around the mounting base. Several supplementary lights are installed on the central camera.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model is equipped with a sliding groove and a sleeve. The fixing block slides inside the sliding groove. The position of the side camera can be changed by sliding. The position of the side camera can be adjusted according to the inner diameter of the pipe to make the distance between the side camera and the inner wall of the pipe the same, so as to avoid the side camera being too close or too far from the inner wall, which would affect the clarity of the side camera's shooting.
[0015] 2. This utility model is equipped with a support leg, a rotating ring, and a fixed ring. The rotation of the rotating ring causes the fixed ring to move up and down, and the up and down movement of the fixed ring causes the support leg to rotate. The rotation of the support leg causes the fixed bracket to expand and contract. The rotation of the fixed bracket can change the position of the wheel. The position of the wheel can be changed according to the inner diameter of the pipe being measured. The wheel is always in contact with the inner diameter of the pipe, which can measure pipes with different inner diameters, greatly improving the application range of the pipe defect detection device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-3 The present invention provides the following technical solution:
[0022] A pipeline defect detection device includes a support rod 1, a mounting base 10, and a central camera 13. The mounting base 10 is installed at the top of the support rod 1, and the central camera 13 is installed on the mounting base 10. A fixed bracket 2 is rotatably connected to the top of the support rod 1 at an equal angle. A wheel 6 is rotatably connected to the end of the fixed bracket 2 via a shaft. A motor 14 is installed at one end of the fixed bracket 2, and the output end of the motor 14 is fixed to the shaft of the wheel 6. The mounting base 10 is installed at the top of the support rod 1, and lighting lamps 11 are installed around the mounting base 10. Several supplementary lights 12 are installed on the central camera 13.
[0023] The pipeline defect detection device is placed inside the pipeline, with the wheels 6 in contact with the inner wall of the pipeline. The power to the motor 14 is turned on, and the motor 14 causes one of the wheels 6 to rotate. The rotation of the wheels 6 allows the entire pipeline defect detection device to move forward inside the pipeline. The lighting lamp 11 provides light to the central camera 13, ensuring sufficient brightness inside the pipeline so that the central camera 13 can take clearer pictures. The design of the supplementary light 12 can assist the photo light in providing a light source for the central camera 13 and the side camera 9, further ensuring sufficient brightness inside the pipeline so that the central camera 13 and the side camera 9 can take clearer pictures. The central camera 13 takes pictures of the four sides of the inner wall of the pipeline, and the pictures taken by the central camera 13 can show the condition of the four walls inside the pipeline.
[0024] A supplementary light 12 is installed around the side camera 9; an adjustment mechanism is provided on the fixed bracket 2, on which the side camera 9 is installed. The adjustment mechanism is used to control the distance between the side camera 9 and the inner wall of the pipe. A rotating ring 4 is threaded onto the support rod 1, and a fixed ring 5 is rotatably connected to the upper end of the rotating ring 4. The fixed ring 5 passes through the support rod 1.
[0025] The adjustment mechanism includes a slide groove 3, a sleeve 7 and a fixing block 8. The upper fixing ring 5 is equipped with a sleeve 7 at an equal angle. The fixing block 8 is installed at the end of the sleeve 7. The fixing bracket 2 has a slide groove 3 inside. The inside of the slide groove 3 is slidably connected to the fixing block 8. The end of the fixing block 8 is equipped with a side camera 9. The slide groove 3 is set parallel to the fixing bracket 2.
[0026] Adjust the position of the side camera 9 according to the inner diameter of the pipe to ensure that the photos taken by the side camera 9 are the clearest. Rotate the upper ring 4 by hand. The upper ring 4 moves synchronously during rotation. The movement of the upper ring 4 causes the upper fixed ring 5 to move synchronously. The movement of the fixed ring 5 causes the sleeve 7 to move synchronously. Since the fixed bracket 2 is tilted after unfolding, the fixed block 8 slides inside the slide groove 3. Therefore, the sleeve 7 extends and retracts during the sliding of the fixed block 8. The movement of the fixed block 8 causes the side camera 9 to move synchronously. The side camera 9 is always set perpendicular to the pipe, so that the photos taken by the side camera 9 are relatively clear. After the side camera 9 is moved to the position where the photo is clearest, stop rotating the upper ring 4.
[0027] The lower fixing ring 5 is rotatably connected to the support leg 15, and the other end of the support leg 15 is rotatably connected to the fixing bracket 2.
[0028] After the pipeline defect detection device is placed inside the pipeline, rotate the lower rotating ring 4 by hand. The rotation of the lower rotating ring 4 causes the lower fixed ring 5 to move up and down. When the fixed ring 5 moves closer to the mounting base 10, the fixed ring 5 moves and causes the support leg 15 to unfold. The unfolding of the support leg 15 pushes the fixed bracket 2, causing the fixed bracket 2 to unfold outward. During the unfolding process of the fixed bracket 2, the wheels 6 are simultaneously unfolded until the lower rotating ring 4 can no longer rotate and stops rotating. At this time, the wheels 6 are in contact with the inner wall of the pipeline. Through the contact between the four wheels 6 and the inner wall of the pipeline, the central camera 13 is kept in the middle of the pipeline.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
