Description

Technical Field

[0001] This utility model relates to the technical field of pipeline inspection robot equipment, specifically to a pipeline inspection robot. Background Technology

[0002] Pipelines are widely used in all aspects of life, and pipeline transportation is prevalent in my country, especially in the petroleum, chemical, nuclear, and urban construction industries. Once pipelines corrode and their walls thin, cracks easily form, leading to oil leaks and other problems, posing significant safety hazards and economic losses. Therefore, regular pipeline inspections are necessary. Currently, the camera modules equipped on pipeline robots are easily contaminated by dirt in the harsh working environment inside pipelines, resulting in decreased image clarity. In such cases, the camera modules need to be manually retrieved and cleaned multiple times, which not only consumes a lot of time and manpower but also negatively impacts the progress of rapid pipeline inspection, reducing overall inspection efficiency. We propose a pipeline inspection robot. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pipeline inspection robot. By incorporating a support component, the height of the inspection unit can be adjusted to select a more favorable inspection height for the camera module. This also helps to mitigate the impact of sludge at the bottom of the pipeline on the camera module. The drive unit, in conjunction with a scraper, prevents the image clarity from decreasing due to sludge adhesion, ensuring the stable operation of the camera module's imaging function.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pipeline inspection robot includes a base with two pairs of wheels mounted on it. The robot is characterized in that a support assembly is mounted on the top of the base, and a detection unit is mounted on the end of the support assembly.

[0006] The support assembly includes a carrier mounted on the top of the base, with hinged support arms at both ends of the carrier. The ends of the support arms are hinged to the same detection unit. Each support arm is also hinged to one end of a telescopic rod, and the other end of the telescopic rod is fixed to the end of the base opposite the carrier.

[0007] The detection unit includes a bracket on which a camera module is mounted. Drive units are installed on both sides of the camera module, and the drive units on both sides are connected to the same scraper.

[0008] Preferably, the camera module consists of a central camera and two auxiliary cameras, and is fitted with a housing on its outer side.

[0009] Preferably, the drive unit includes a slide rail mounted on the side wall of the bracket, and an adapter slider is slidably connected on the slide rail. The front end of the slider is connected to one end of the scraper. A rotating cylinder is arranged behind the slider. A track is opened on the rotating cylinder. A guide post is installed on the slider. The guide post can move along the track. The track is wavy in shape.

[0010] Preferably, the scraper is equipped with a brush strip.

[0011] Preferably, the drive unit is fitted with a housing on its outer side, the housing is sealed at each connection point, and an arched protective strip is installed on the lower half of the housing.

[0012] Preferably, a spotlight is also installed on the bracket, located above the camera module.

[0013] This utility model provides a pipeline inspection robot. It has the following advantages: by incorporating a support component, the height of the inspection unit can be adjusted, allowing for a more favorable inspection height for the camera module. Simultaneously, it can mitigate the impact of sludge at the bottom of the pipeline on the camera module to some extent. The use of a drive unit in conjunction with a scraper prevents image clarity degradation due to sludge adhesion, ensuring the stable operation of the camera module's imaging function.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1-3 A pipeline inspection robot includes a base 1 with two pairs of wheels mounted on it to facilitate stable movement of the vehicle.

[0026] The top of the base 1 is equipped with a support component 2, and the end of the support component 2 is equipped with a detection unit 3.

[0027] The support assembly 2 includes a support member 21 mounted on the top of the base 1. Support arms 22 are hinged to both ends of the support member 21. The ends of the support arms 22 are hinged to the same detection unit 3. One end of a telescopic rod 23 is also hinged to each support arm 22. The other end of the telescopic rod 23 is fixed to one end of the base 1 relative to the support member 21. The lifting or lowering of the support arm 22 is controlled by the extension and retraction of the telescopic rod 23.

[0028] Each end of an auxiliary arm 24 is also installed at both ends of the support member 21. Similarly, the ends of the auxiliary arms 24 at both ends are respectively hinged to the detection unit 3.

[0029] The detection unit 3 includes a bracket 31, on which a camera module 32 is mounted. This module is used to collect information about the inside of the pipeline. Simultaneously, the camera module 32 establishes a communication connection with the control computer, enabling it to transmit the collected information back to the control computer in real time, providing data support for construction personnel to conduct analysis. Furthermore, the camera module 32 consists of a central camera and two auxiliary cameras, and is equipped with a housing 33 on its outer surface. This housing 33 protects the lenses from damage during operation.

[0030] A drive unit 4 is installed on each side of the camera module 32. The drive units 4 on both sides are connected to the same scraper 41. The scraper 41 can clean the housing 33 of the camera module 32 to prevent the camera from being affected by mud during operation, which would result in unclear images.

[0031] The drive unit 4 includes a slide rail mounted on the side wall of the bracket 31, and an adapter slider is slidably connected on the slide rail. The front end of the slider is connected to one end of the scraper 41. A rotating cylinder 42 is arranged behind the slider. A track is opened on the rotating cylinder 42. A guide post is installed on the slider. The guide post can move along the track. The track is wavy and can drive the slider to move up and down.

[0032] The scraper 41 is equipped with a brush strip, which can wash away the mud on the housing 33 of the camera module 32, so as to avoid the image clarity being reduced due to the mud adhesion and ensure the stable performance of the imaging function of the camera module 32.

[0033] To protect the drive unit 4 from being immersed in sludge or sewage from the pipe, a housing is fitted on the outside of the drive unit 4, and the housing is sealed at all joints.

[0034] In some embodiments, there are two scrapers 41, one above the other. Correspondingly, there are two rotating drums 42, also one above the other, and the two rotating drums 42 are connected to the same rotating shaft, so that they can rotate simultaneously and allow the two scrapers 41 to move together.

[0035] The lower half of the shell is equipped with a protective strip 5. The protective strip 5 adopts an arched structure design, which can effectively protect the lower half of the shell and reduce damage to the shell caused by external collisions, friction and other factors. On the other hand, relying on the mechanical properties and morphological advantages of the arched structure, the protective strip 5 also has the function of removing obstacles in sewage and optimizing the sewage flow path, ensuring the stable operation of related equipment in sewage operation scenarios.

[0036] A spotlight 6 is also installed on the bracket 31, located above the camera module 32, to provide lighting for the camera module 32.
