Description

Technical Field

[0001] This utility model relates to the technical field of self-propelled devices, and more specifically, to a CCTV pipeline inspection device. Background Technology

[0002] Pipeline CCTV inspection, as a highly efficient and advanced method for pipeline health inspection, was introduced to China in the mid-1990s and has been widely used internationally. Its principle involves using an advanced CCTV endoscopic television inspection system, employing an automated crawling or walking device to penetrate deep into the pipeline. During the inspection, the camera on the device accurately detects and images the rust, scale, corrosion, perforations, cracks, and other conditions inside the pipeline, recording the actual situation in real time. Inspectors can conveniently control the crawling device's speed and direction from the ground via a main controller and can clearly view the video images inside the pipeline.

[0003] However, problems arise when the top of the pipeline collapses. The collapse creates obstacles within the pipeline, which conventional crawling or walking equipment often struggles to overcome due to its structural limitations and movement patterns. Once obstructed, the planned inspection of subsequent pipeline sections cannot proceed, interrupting the inspection process and requiring additional time and effort to resolve the obstruction, significantly impacting the overall efficiency of pipeline inspection. Therefore, to ensure the smooth operation of pipeline CCTV inspections, there is an urgent need to design a self-propelled device capable of efficiently traversing obstacles to handle complex pipeline conditions. Utility Model Content

[0004] The purpose of this invention is to provide a CCTV pipeline inspection device that can efficiently overcome obstacles in pipelines and improve the efficiency of pipeline inspection.

[0005] This utility model is achieved through the following technical solution: The CCTV pipeline inspection device of this utility model includes a vehicle body, a first camera disposed at the end of the vehicle body, rollers disposed around the vehicle body, and an auxiliary device disposed above the vehicle body; the auxiliary device includes a horizontally disposed support plate, a plurality of auxiliary wheels horizontally disposed on the side of the support plate, a motor connected to the auxiliary wheels, and a drive device connected to the support plate; the auxiliary wheels are disposed close to the inner wall of the pipeline, and the drive device is used to drive the vehicle body to move closer to / away from the support plate.

[0006] Furthermore, the auxiliary device also includes a support rod connected to the auxiliary wheel and arranged horizontally; one end of the support rod is connected to the support plate, and the other end is rotatably connected to the roller; the roller's shaft is rotatably connected to the support rod.

[0007] Furthermore, the length direction of the support rod is perpendicular to the length direction of the vehicle body; the support rod is slidably connected to the support plate.

[0008] Furthermore, the side wall of the support plate is provided with multiple insertion holes, and one of the support rods is inserted into one of the insertion holes; the side wall of the support plate is threaded with multiple fastening bolts, and one of the fastening bolts abuts against one of the support rods.

[0009] Furthermore, the driving device includes an electric push rod inverted and disposed on the upper side of the support plate; the telescopic part of the electric push rod passes through the support plate and is fixedly connected to the vehicle body.

[0010] Furthermore, the drive device also includes a plurality of vertically mounted slide rods on the vehicle body and slide holes formed on the support plate, wherein one slide rod is slidably disposed in one of the slide holes.

[0013] Furthermore, the first camera is tilted upwards, and the second camera is tilted downwards.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the CCTV pipeline inspection device of this utility model involves placing the vehicle body into the pipeline. The height of the support plate is adjusted according to the diameter of the pipeline to ensure the support plate is aligned with the horizontal axis of the pipeline. Then, the position of the rollers is adjusted so that they are close to the inner wall of the pipeline but avoid direct contact. The rollers then drive the vehicle body and the auxiliary device to move within the pipeline. During this movement, the internal condition of the pipeline can be observed in real time through a first camera, allowing for inspection and recording of the internal conditions. When an obstacle is observed to have collapsed above the pipe or fallen into it, the drive unit on the support plate pulls the vehicle closer to the auxiliary device. Initially, the support plate descends until the auxiliary wheels contact the inner wall of the pipe, at which point the descent stops. The drive unit then continues to operate, pulling the vehicle upwards to a height sufficient to cross the obstacle. The motor on the auxiliary wheels then operates, driving the wheels to rotate and roll along the inner wall of the pipe, thus propelling the support plate, vehicle, and other structures over the obstacle. The drive unit then lowers the vehicle back to its previous position and continues moving forward. Throughout this process, it can effectively overcome conventional obstacles (such as accumulated obstacles or potholes), enabling efficient and comprehensive inspection of the pipe's interior.

[0021] Example

[0022] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 5 As shown, the CCTV pipeline inspection device in this embodiment includes a vehicle body 20, a first camera 22 located at the end of the vehicle body 20, rollers 21 located around the vehicle body 20, and an auxiliary device 30 located above the vehicle body 20. The auxiliary device 30 includes a horizontally arranged support plate 31, multiple auxiliary wheels 32 horizontally arranged on the sides of the support plate 31, a motor 33 connected to the auxiliary wheels 32, and a drive device connected to the support plate 31. The auxiliary wheels 32 are located close to the inner wall of the pipeline 10, and the drive device is used to drive the vehicle body 20 closer to / away from the support plate 31. Specifically, in use, the vehicle body 20 is placed into the pipeline 10, and the height of the support plate 31 is adjusted according to the diameter of the pipeline 10 so that the support plate 31 is on the horizontal axis of the pipeline 10. Then, the position of the rollers 21 is adjusted so that the rollers 21 are close to the inner wall of the pipeline 10 but do not contact the inner wall of the pipeline 10 as much as possible. Then, the rollers 21 drive the vehicle body 20 and drive the auxiliary device 30 to move in the pipeline 10 (as shown in the attached figure). Figure 1 and attached Figure 3 As shown in the attached diagram, during the movement, the first camera 22 can be used to observe the inside of the pipe 10 in real time, and to inspect and record the situation inside the pipe 10. When an obstacle is observed to have collapsed or fallen into the pipe 10, the drive device on the support plate 31 will pull the vehicle body 20 closer to the auxiliary device 30. At the beginning of the movement, the support plate 31 will descend until the auxiliary wheel 32 contacts the inner wall of the pipe 10, at which point the support plate 31 will stop descending. At this time, the drive device will continue to operate, pulling the vehicle body 20 upward (as shown in the attached diagram). Figure 2 and attached Figure 4 As shown, after raising the vehicle body 20 to a height sufficient to cross obstacles, the motor 33 on the auxiliary wheel 32 operates, driving the auxiliary wheel 32 to rotate. This causes the auxiliary wheel 32 to roll on the inner wall of the pipe 10, thereby helping the support plate 31, vehicle body 20, and other structures to cross obstacles. Then, the drive device lowers the vehicle body 20 back to its previous state and continues moving forward. Throughout the process, it can easily cross common obstacles (such as piled-up obstacles or potholes), enabling efficient all-around inspection of the inside of the pipe 10. It should be noted that the vehicle body 20 itself is designed with a battery, motor, and steering mechanism to drive the roller 21 to rotate and steer. This type of structure can use the structure of a common electric four-wheeled vehicle. Furthermore, the vehicle body 20 can be controlled remotely by hand or connected to the vehicle body 20 via wires for wired control. The video signal captured by the first camera 22 can also be transmitted via wires or wirelessly.

[0023] The auxiliary device 30 in this embodiment also includes a support rod 35 connected to the auxiliary wheel 32 and horizontally arranged; one end of the support rod 35 is connected to the support plate 31, and the other end is rotatably connected to the roller 21; the axle of the roller 21 is rotatably connected to the support rod 35. The length direction of the support rod 35 is perpendicular to the length direction of the vehicle body 20; the support rod 35 is slidably connected to the support plate 31. Specifically, this allows the length of the support rod 35 extending out of the support plate 31 to be adjusted according to the diameter of the pipe 10, thereby adjusting the distance between the auxiliary wheel 32 and the inner wall of the pipe 10.

[0024] In this embodiment, the support plate 31 has multiple insertion holes 36 on its side wall, and a support rod 35 is inserted into one insertion hole 36. Multiple fastening bolts 37 are threaded onto the side wall of the support plate 31, and one fastening bolt 37 abuts against one support rod 35. Specifically, the length of the support rod 35 can be adjusted by adjusting the depth of its insertion into the insertion hole 36, and then the support rod 35 can be locked in place with the fastening bolts 37.

[0025] The driving device in this embodiment includes an electric push rod 34 inverted and mounted on the upper side of the support plate 31; the telescopic part of the electric push rod 34 passes through the support plate 31 and is fixedly connected to the vehicle body 20. Specifically, during normal movement without obstacles, the electric push rod 34 serves to support the support plate 31. When encountering an obstacle, the electric push rod 34 can pull the vehicle body 20 away from the bottom wall of the pipe 10, bringing it closer to the support plate 31, and then allowing it to cross the obstacle. The electric push rod 34 can adopt a multi-stage structure to reduce the length of the cylinder and increase the range of motion.

[0026] The driving device in this embodiment also includes multiple vertically mounted sliding rods 39 on the vehicle body 20, and sliding holes formed on the support plate 31, with one sliding rod 39 slidably disposed in one sliding hole. The driving device also includes multiple vertically mounted sleeves 38, with one sleeve 38 fixedly disposed at one sliding hole, and one sliding rod 39 slidably disposed in one sleeve 38. Specifically, the cooperation of the sliding rods 39 with the sliding holes and sleeves 38 enables the vehicle body 20 to maintain a relatively parallel state with the support plate 31, and the vehicle body 20 will not easily tip over with the assistance of the support plate 31.

[0027] In this embodiment, a second camera 310 is also provided at the end of the support plate 31, and the first camera 22 and the second camera 310 are provided at the same end of the vehicle body 20. The first camera 22 is tilted upwards, and the second camera 310 is tilted downwards. Specifically, the arrangement of the first camera 22 and the second camera 310 can effectively expand the field of view, and the first camera 22 at the bottom is facing upwards, while the second camera 310 at the top is facing downwards, which allows for better observation of the inner wall of the pipe 10.

[0028] In summary, the CCTV pipeline inspection device of this embodiment involves placing the vehicle body 20 into the pipeline 10 during use. The height of the support plate 31 is adjusted according to the diameter of the pipeline 10, ensuring the support plate 31 is aligned with the horizontal axis of the pipeline 10. The position of the rollers 21 is then adjusted so that they are close to the inner wall of the pipeline 10 but avoid direct contact. The rollers 21 drive the vehicle body 20 and the auxiliary device 30 to move within the pipeline 10. During this movement, the first camera 22 can be used to observe the internal condition of the pipeline 10 in real time, allowing for inspection and recording. When a collapse is observed above the pipeline 10... When the vehicle collapses or falls into an obstacle in the pipe 10, the drive device on the support plate 31 pulls the vehicle body 20 closer to the auxiliary device 30. Initially, the support plate 31 descends until the auxiliary wheel 32 contacts the inner wall of the pipe 10, at which point the support plate 31 stops descending. The drive device then continues to operate, pulling the vehicle body 20 upwards. Once the vehicle body 20 is raised to a height sufficient to cross the obstacle, the motor 33 on the auxiliary wheel 32 operates, driving the auxiliary wheel 32 to rotate. This causes the auxiliary wheel 32 to roll on the inner wall of the pipe 10, thereby helping the support plate 31, vehicle body 20, and other structures to cross the obstacle. The drive device then lowers the vehicle body 20 back to its previous position and continues moving forward. Throughout the process, it can effectively cross conventional obstacles (such as piled-up obstacles or potholes), enabling efficient all-around inspection of the inside of the pipe 10.

Various modifications and variations can be made to this utility model by those skilled in the art.
