Furthermore, pipelines can also be affected by uncontrollable factors, such as natural and human factors, causing defects and damage. Therefore, monitoring the health of pipelines is crucial for pipeline maintenance.
[0003] Existing pipeline internal inspection devices have several issues. For pipelines with varying depths and diameters, the device's external movable structure cannot automatically adjust to the operating conditions. Consequently, the device cannot adapt to pipelines with varying depths and diameters, resulting in the device becoming immobile or experiencing poor detection performance when operating in these diverse pipelines. Existing pipeline internal inspection devices often utilize a drive wheel with a telescopic component to adjust the device's external movable structure. However, this approach, in addition to limiting the telescopic length, also suffers from the inflexible and inconvenient adjustment of the drive wheel.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0042] The utility model provides a pipeline internal detection imaging device, such as Figure 1 As shown, the pipeline internal detection imaging device includes: a main box 100, which is a box-shaped structure and serves as the main structure of the pipeline internal detection imaging device; a plurality of hub structures 200, which are respectively arranged at various vertex positions outside the main box 100 to support the stable operation of the main box 100 in the pipeline; a driving device, which is connected to each of the hub structures 200 and can control the operation of the hub structures 200; and a remote control device, which is wirelessly connected to the driving device and can remotely operate the driving device.
[0043] In a specific embodiment of the present invention, the main body box 100 adopts a rectangular parallelepiped structure, and therefore eight hub structures 200 are correspondingly adopted and respectively installed at eight vertex areas outside the main body box 100 .
[0044] Among them, Figure 2As shown in Figures (a) and (b), the hub structure 200 includes: a hub middle piece 201, one end of which is connected to the main box 100; and a variable axle drive assembly 202, which can be adjustably connected to the other end of the hub middle piece 201 to change the axle length between the hub middle piece 201 and the variable axle drive assembly 202.
[0045] like Figure 2 As shown in FIG. 1 (a), the hub intermediate component 201 includes a threaded bolt 211, one end of which is connected to the main body case 100; and a first hub mounting portion 212, which is cylindrical and connected to the other end of the threaded bolt 211. The first hub mounting portion 212 is used to mount the variable axle drive assembly 202. A cylindrical thread groove 213 is provided inside the first hub mounting portion 212, and a first thread structure is formed in the cylindrical thread groove 213.
[0046] Preferably, the first hub mounting portion 212 is connected to an end of the threaded bolt 211 close to the first hub mounting portion 212 by welding.
[0047] like Figure 2 As shown in Figure (b), the variable wheel axle drive assembly 202 includes: a second wheel hub mounting portion 221, which is a cylindrical structure, and the outer diameter of the cylindrical surface of the second wheel hub mounting portion 221 matches the inner diameter of the cylindrical thread groove 213, and one end of the second wheel hub mounting portion 212 can be extended into the cylindrical thread groove 213 in the first wheel hub mounting portion 212; a wheel hub column 222, one end of which is connected to the other end of the second wheel hub mounting portion 221; a driving wheel 223, which is arranged at the other end of the wheel hub column 222 and is connected to the driving device to drive the driving wheel 223 to rotate through the driving device.
[0048] In a specific embodiment of the present invention, the hub column 222 is connected to the driving wheel 223 via a wheel bolt 224 .
[0049] The cylindrical surface of the second hub mounting portion 221 is provided with a second thread structure, which can cooperate with the first thread structure. Therefore, the second hub mounting portion 221 can be movably connected to the first thread structure of the cylindrical thread groove 213 on the first hub mounting portion 212 through the second thread structure on its cylindrical surface.
[0050] The length of the wheel axle between the variable wheel axle drive assembly 202 and the wheel hub intermediate component 201 is adjusted by the relative matching position between the first thread structure and the second thread structure.
[0051] Specifically, after the second hub mounting portion 221 is screwed into the cylindrical thread groove 213 of the first hub mounting portion 212, the second hub mounting portion 221 is continued to be rotated until it is fully tightened, that is, the second thread structure thereon is fully matched with the first thread structure on the first hub mounting portion 212. At this time, the axle between the variable axle drive assembly 202 and the hub middle piece 201 reaches the shortest state to adapt to the pipe with a smaller inner diameter; when the second hub mounting portion 221 is rotated in the opposite direction, the number of matching circles of the second thread structure thereon and the first thread structure on the first hub mounting portion 212 is reduced, that is, the second hub mounting portion 221 gradually moves away from the first hub mounting portion 212. At this time, the axle between the variable axle drive assembly 202 and the hub middle piece 201 reaches the longest state to adapt to the pipe with a larger inner diameter.
[0052] Furthermore, a stop structure is provided on the circle of threads of the second thread structure closest to the head of the second hub mounting portion 221. When only the last circle of the second thread structure on the second hub mounting portion 221 is matched with the first thread structure on the first hub mounting portion 212, the stop structure limits the second hub mounting portion 221 from being further separated from the first hub mounting portion 212.
[0053] Preferably, the stop structure is a convex groove, which is provided at the end of the thread circle of the second thread structure closest to the head of the second hub mounting portion 221. When only the last thread circle of the second thread structure on the second hub mounting portion 221 is left to mate with the first thread structure on the first hub mounting portion 212, the last thread circle cannot be further screwed out due to the obstruction of the convex groove.
[0054] Furthermore, the adjustment range of the wheel axle between the variable wheel axle drive assembly 202 and the wheel hub intermediate component 201 is 0-3m.
[0055] Among them, the eight vertex corners of the main box 100 are all triangular plane structures, and a threaded hole matching the threaded bolt 211 is opened in the triangular plane area at each vertex, and these threaded holes are used to install the threaded bolt 211; after the end of the threaded bolt 211 away from the first hub mounting part 212 is screwed into the main box 100, the wheel hub middle part 201 and the main box 100 are fixedly connected.
[0056] The main body box 100 is embedded with a scanning device to detect and sense the internal environment of the pipeline, that is, to detect defects inside the pipeline and avoid obstacles inside the pipeline; specifically, the present invention adopts a laser radar scanning device.
[0057] The main box 100 is further provided with a camera device, which is located near the front side of the main box 100 and is used for collecting data on the inner wall of the pipeline, capturing damage, and recording videos.
[0058] like Figure 3 The figure shows a schematic diagram of the pipeline internal detection imaging device operating in vertical and horizontal pipelines. The main housing 100 is also provided with several transmitting holes 101, located on the four first side walls of the housing 100 facing the annular pipeline, for transmitting laser beams emitted by the lidar scanning device to detect the internal conditions of the pipeline. A camera hole 102, located on the second side wall of the main housing 100 on the forward side, is used by the imaging device to capture the conditions inside the pipeline ahead.
[0059] In a specific embodiment of the present invention, a plurality of emitting holes 101 are provided at intervals on the first side wall of the main box 100 facing the annular pipe; specifically, one emitting hole 101 is provided on each of the four first side walls facing the annular pipe, that is, the main box 100 is provided with four emitting holes 101 facing the annular pipe.
[0060] In a specific embodiment, the driving device is a motor.
[0061] In addition, the camera device is connected to an external display device for communication, so that the data collected by the camera device, the damaged captured images, and the recorded videos can be viewed through the external display device. The laser radar scanning device is connected to an external display device for communication, so that the scanned information can be uploaded to the external display.
[0062] The specific operation mode of the utility model is as follows:
[0063] Step S1: Before placing the pipeline interior detection imaging device into the pipeline, measure the inner diameter of the pre-detected pipeline and adjust the axle distance between the variable axle drive assembly 202 and the hub intermediate member 201 so that each driving wheel 223 of the pipeline interior detection imaging device fits the inner wall of the pipeline;
[0064] Step S2: placing the pipeline interior detection imaging device with the wheel axle adjusted into the pipeline;
[0065] Step S3, start the motor of the pipeline internal detection imaging device, and then control the motor through the remote control device, thereby driving the hub structure 200, and finally realizing the operation of the pipeline internal detection imaging device in the pipeline. During the operation of the pipeline internal detection imaging device, the camera device collects data in the pipeline in front of the operation in real time, captures damaged parts, and records them with video. The operator can see the situation inside the pipeline collected by the camera device through the external display device. At the same time, the laser radar scanning device can perform a 360° circular scan of the pipeline inner wall around the operating position of the pipeline internal detection imaging device in real time to detect defects inside the pipeline and avoid obstacles. The circular scanning of the laser radar scanning device can generate three-dimensional structural data inside the pipeline to further analyze the internal situation of the pipeline;
[0066] When the pipeline internal detection imaging device encounters an obstacle, the laser radar scanning device can display the detected obstacle information on an external display device, and control the pipeline internal detection imaging device to avoid the obstacle through a remote control device;
[0067] Step S4: After the pipeline interior detection imaging device has detected a complete section of the pipeline, it moves to the outlet at the other end of the pipeline, turns off the motor, and takes out the pipeline interior detection imaging device.
[0068] In summary, the utility model provides a pipeline internal detection imaging device, which can adaptively adjust the imaging detection device according to different pipeline structures and pipe diameters, so that it can smoothly move and detect along the inner wall of the pipeline; in addition, through the combination of the camera device and the laser radar scanning device, the environment inside the pipe is better detected. At the same time, the control of the pipeline internal detection imaging device by the remote control device improves the operability and intelligence level of the detection imaging device.
[0069] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be construed as limiting the present invention. After reading the above description, various modifications and alternatives to the present invention will become readily apparent to those skilled in the art. Therefore, the scope of protection of the present invention shall be defined by the appended claims.
