Description

Technical Field

[0001] This utility model relates to a self-propelled inspection device for building pipelines, specifically a self-propelled inspection device for building pipelines, belonging to the field of building pipeline inspection technology. Background Technology

[0002] Building pipelines are tubular devices used to transport liquids, gases, or bulk solids. Over time, pipelines can develop cracks and deformities due to corrosion, impacts, and other factors. To ensure the normal operation of various pipeline systems within buildings, it is necessary to use testing devices to conduct regular inspections of building pipelines.

[0003] A self-propelled pressure pipeline inspection device is disclosed in Chinese Patent Application Publication CN222419974U. This device can clean and collect debris attached to the surface of the pressure pipeline, avoiding the influence of debris on the infrared light emitted by the infrared detection probe, ensuring the accuracy of the infrared detection probe in pipeline inspection, and thus improving the detection effect.

[0004] However, in the implementation of the above-mentioned patented technical solution, the detection device cannot be adapted to pipes of various diameters. Existing building pipes have various diameter specifications according to different uses and different usage requirements. In order to ensure that the walking wheels fit the outer wall of the pipe, most of the existing self-propelled detection devices can only be adapted to pipes of specific diameters, and the scope of application is relatively small.

[0005] Therefore, a self-propelled inspection device for building pipelines is proposed here. Utility Model Content

[0006] This utility model proposes a self-propelled inspection device for building pipelines to solve the problem that existing building pipeline inspection devices cannot be adapted to pipelines of various diameters.

[0007] This utility model is achieved through the following technical solution: a self-propelled inspection device for building pipelines, including a support plate, an inspection mechanism is provided on the outside of the support plate, the inspection mechanism includes a hollow tube and a movable plate, the hollow tube passes through the support plate and is rotatably connected to the support plate, a spring is fixedly connected to one end of the hollow tube near the movable plate, the end of the spring away from the hollow tube is fixedly connected to the outer surface of the movable plate, and an infrared detection probe is fixedly connected to one side of the movable plate away from the support plate;

[0008] An adjustment mechanism is provided on the outside of the support plate. The adjustment mechanism includes two symmetrical support semi-rings, two symmetrical adjustment semi-rings, and four electric self-propelled wheels.

An L-shaped rod is fixedly connected to the outer surface of each of the four electric self-propelled wheels. The L-shaped rod is slidably connected to the inner wall of the adjustment semi-ring. A second telescopic rod is fixedly connected to the outer surface of each of the four electric self-propelled wheels. The end of the second telescopic rod away from the electric self-propelled wheel is fixedly connected to the outer surface of the support semi-ring.

[0009] Preferably, a sliding rod is slidably connected to the inner wall of the hollow tube. The sliding rod passes through the moving plate and is rotatably connected to the moving plate. A brush is fixedly connected to the end of the sliding rod away from the hollow tube. The brush can clean dust and other debris on the surface of the pipe, thereby ensuring the accuracy of the infrared detection probe.

[0010] The outer surface of the aforementioned sliding rod is fixedly connected to two symmetrical anti-detachment sliders. Both anti-detachment sliders are slidably connected to the inner wall of the hollow tube. The hollow tube is provided with a limiting groove that matches the anti-detachment slider. The sliding of the anti-detachment slider within the upper limiting groove of the hollow tube can prevent the sliding rod from detaching from the hollow tube, while ensuring that the sliding rod can rotate when the hollow tube rotates.

[0011] Specifically, a first telescopic rod is fixedly connected to the outer surface of the movable plate. The end of the first telescopic rod away from the movable plate is fixedly connected to the outer surface of the support plate. The first telescopic rod is a hollow tube that guides the movement of the support plate.

[0012] Preferably, the detection mechanism further includes a first motor fixedly connected to the outer surface of the support plate and a sliding frame fixedly connected to the outer surface of the support plate. The sliding frame is slidably connected to the support half ring. A rotating wheel is fixedly connected to the output shaft end of the first motor. The rotating wheel is adapted to the support half ring. A reserved groove adapted to the rotating wheel is opened on the support half ring. When the rotating wheel rotates in the reserved groove of the support half ring, the support plate can make a circular motion along the support half ring.

[0013] A first bevel gear is fixedly connected to the outer surface of the output shaft of the first motor, and a second bevel gear is fixedly connected to the end of the hollow tube away from the spring. The first bevel gear and the second bevel gear mesh, and the first motor can drive the hollow tube to rotate through the first bevel gear and the second bevel gear when it is running.

[0014] Specifically, guide rails are fixedly connected to the outer surfaces of both supporting semi-rings, and the adjusting semi-ring is slidably connected to the guide rails. The guide rails guide the rotation of the adjusting semi-ring relative to the supporting semi-ring.

[0017] 1. This self-propelled building pipeline inspection device, through the setting of inspection and adjustment mechanisms, can be adapted to the inspection of various specifications of pipelines within a certain range. Compared with existing pipeline inspection devices that can only be adapted to specific specifications, it has a wider range of applications, so as to meet the inspection of various pipelines in building pipelines and is easy to use.

[0018] 2. This self-propelled inspection device for building pipelines controls the operation of the first motor through the setting of the inspection mechanism. This motor drives the rotating wheel and the brush to rotate, so that the brush is in close contact with the surface of the pipeline for cleaning. At the same time, the support plate can move in a circle along the support semi-ring, so that the brush and the infrared detection probe can move in a circle. Thus, while cleaning the pipeline, the infrared detection probe can detect the pipeline, avoiding the influence of debris on the pipeline surface on the inspection results.
