Description

Technical Field

[0001] This utility model relates to the field of pipeline internal inspection technology, and in particular to a general-purpose robot for airflow shuttle pipeline inspection. Background Technology

[0002] With the increasing prevalence of the pipeline industry, pipeline inspection technology is also developing rapidly. Currently, manual pipeline inspection is not only dangerous but also inefficient. Existing pipeline inspection robots are mostly ill-suited to pipes of different sizes, often requiring multiple equipment changes during inspection, and cannot achieve omnidirectional inspection; their travel speed is also not freely adjustable. Therefore, we decided to develop a new type of pipeline inspection robot that can adapt to various environments, especially handling the variability in pipe size and application scenarios, thereby effectively improving the efficiency and quality of pipeline inspection. Utility Model Content

[0003] The main purpose of this utility model is to provide a universal airflow shuttle robot for pipeline inspection. By setting up the robot, it solves the problems that existing pipeline inspection robots are mostly unable to adapt to pipelines of different sizes, often require multiple equipment changes during inspection, cannot achieve all-round inspection, and cannot freely adjust their travel speed.

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

[0005] The airflow shuttle-type general-purpose robot for pipeline inspection is modularly designed, comprising four parts: a blunt-shaped unit, a detection unit, a viewing window unit, and a power unit.

[0006] The blunt unit includes a front section of the device, the front end of which is provided with a streamlined energy-absorbing structure, and the rear end of which is provided with a connection component connected to the detection unit.

[0007] The detection unit is located inside the front end of the device and includes a rotatable circular turntable located inside the front end of the device and a motor assembly connected to the turntable, a camera module integrated on the circular turntable, and a stepper motor for driving the turntable located on one side of the circular turntable.

[0008] The viewing window unit is located at one end of the front section of the device. Flange connection parts are provided on both sides of the viewing window unit. One end of the viewing window unit is connected to the front section of the device through the flange connection part, and the other end of the viewing window unit is connected to the device body through the flange connection part. The viewing window unit can be assembled and disassembled with the front and rear connection parts.

[0009] The power unit includes a split cylinder disposed at one end of the device body, an axial fan blade assembly disposed inside the device body, and a traveling mechanism. It also includes a locking component connecting the device body and the split cylinder. The traveling mechanism has a telescopic arm and an adaptive roller. A pressure sensor is provided at the end of the telescopic arm.

[0010] Preferably, the flange connection portion on both sides of the window unit has a specific structure in which flanges are installed on both sides of the connection port, a flange gasket is installed in the middle, and bolts are used to fasten the flanges.

[0011] Preferably, the axial fan blade assembly of the power unit includes a fan blade cylinder fixedly connected to the inside of the device body, a generator disposed inside the fan blade cylinder, a shaft hole opened inside the fan blade cylinder, a shaft disposed inside the shaft hole, multiple fan blades fixedly connected to the outside of the fan blade cylinder, a fan blade front section disposed at the top of the fan blade cylinder, two semi-circular components connected to the fan blade cylinder, and a strip-shaped optimized structure connected to the tail of the fan blade cylinder.

[0012] Preferably, one end of the telescopic arm in the walking mechanism of the power unit is fixedly connected to the device body, and a spring component sleeve is provided inside the telescopic arm.

[0013] When the device is decelerating or even when the power unit is working, the built-in telescopic support arm extends to seal the split cylinder at the rear of the device, guiding the airflow to be discharged from the power unit. By changing the direction of the airflow, the detection function is achieved.

[0014] Preferably, the fan blade cylinder in the power unit is truncated cone-shaped.

[0015] Preferably, the outer casing of the window unit has multiple air inlets.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. In this utility model, the flange connection on both sides of the viewing window unit facilitates the replacement of the testing instrument by removing the bolts as needed, and makes it convenient to check whether the camera in the testing area is damaged, thus improving the convenience of maintenance and inspection.

[0018] Second, in this utility model, the axial fan assembly of the power unit is used as the driving device to rotate and push air in the closed pipe. The forward rotation generates thrust to assist the wheel drive, reduce the wheel load during long-distance detection, and solve the problem of insufficient power during the detection process.

[0019] Third, in this utility model, the walking mechanism of the power unit, including the locking component on the outside of the device body, the telescopic support arm with the spring component and telescopic rod, and the walking mechanism with embedded adaptive rollers, enables the detection robot to work in various types of pipe diameters. At the same time, it can avoid the problem that the robot cannot pass through a pipe with a changing diameter due to size issues. Compared with robots already on the market, its adaptability is better.

[0020] Fourth, in this utility model, by leaving a separate cylinder in the power unit and connecting it with a locking assembly, the exploration robot can slow down or return when it encounters an insurmountable obstacle, which is achieved by adjusting the airflow. Attached Figure Description
