Technical Field

[0001] This utility model relates to the field of spiral fan-blade driven robot technology, and in particular to a spiral fan-blade driven general-purpose robot used for pipeline flaw detection. 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.

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.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a general-purpose spiral fan-blade driven robot used for pipeline flaw detection includes a blunt-shaped unit, a detection unit, a viewing window unit, and a power unit.

[0028] The blunt unit includes a device front end 1, which has a blunt streamlined structure, and a connection component for connecting to the detection unit is provided at the tail end of the device front end 1.

[0029] The detection unit includes an internally rotatable disc equipped with ultrasonic testing and a small electromechanical component located inside the front end 1 of the device.

[0030] The window unit includes a device window portion 2 disposed at one end of the front end 1 of the device;

[0031] The power unit includes a device movement part 3 located at one end of the device window part 2. The device movement part 3 has a longitudinal fan blade assembly driven by a motor inside, and the outer shell of the device movement part 3 is threaded.

[0032] Flange connection parts are provided on both sides of the device window part 2. One end of the device window part 2 is connected to the front end 1 of the device through the flange connection part, and the other end of the device window part 2 is connected to the moving part 3 of the device through the flange connection part. The device window part 2 can be assembled and disassembled with the front and rear connection parts.

[0033] The specific structure of the flange connection consists of flanges installed on both sides of the connection port, a flange gasket installed in the middle, and bolts for fastening the flanges.

[0034] The device window section 2 has an internal perforated grid surface 4 and multiple air vents 5 on the surface of the device window section 2.

[0035] The internal perforated surface 4 can guide airflow in, and the air vent 5 can swing up and down to guide airflow in the opposite direction.

[0036] The axial fan blade assembly of the power unit includes a fan blade cylinder 9 fixedly connected inside the moving part 3 of the device, a motor disposed inside the fan blade cylinder 9, a fan blade hole 6 opened inside the fan blade cylinder 9, a connecting rod 10 disposed inside the fan blade hole 6, a plurality of fan blades 8 fixedly connected to the outside of the fan blade cylinder 9, and a fan blade front end 7 disposed at the top of the fan blade cylinder 9.

[0037] The material of the front end 1 of the device in the blunt unit is silicone rubber coating.

[0038] Silicone rubber coatings are highly elastic and can buffer impact energy, reducing internal impact. They are flexible, not easy to crack or peel off, and have good stability, making them adaptable to various environments.

[0039] The robot's outer shell is made of aluminum bottle wrapped with carbon fiber.

[0040] The aluminum bottle is wrapped with carbon fiber. Aluminum has a low density, which can effectively reduce the overall weight of the robot, making the robot more flexible during operation and reducing energy consumption.

[0041] The detachable flange structure on both sides of the viewing unit facilitates the replacement of testing instruments by removing bolts as needed, and makes it easy to check whether the camera in the testing area is damaged, thus improving the convenience of maintenance and inspection.

[0042] In this invention, the axial fan assembly of the power unit is used as the driving device to rotate and push air in a closed pipe. The forward rotation generates thrust to assist the spiral to move forward, thus solving the problem of insufficient power during the detection process.

[0043] In this invention, the moving part 3 of the device solves the problems of inadequate detection and insufficient contact that cause the device to slip. Compared with robots already on the market, it has better adaptability.

[0044] In this invention, regarding materials, the front end of the device is coated with silicone rubber. Due to its high elasticity and flexibility, it can effectively buffer collision energy and reduce internal impact. Furthermore, silicone rubber coating has good chemical stability, is corrosion-resistant, and is suitable for various environments.

[0045] Viewing window: Made of UTG ultra-thin flexible glass, its main components are silicon dioxide and other oxides. It has the characteristics of high hardness, good transparency, high temperature resistance and corrosion resistance, and can be used in high temperature and corrosive pipeline environments.

[0046] Outer shell: A composite structure of aluminum cylinder wrapped with carbon fiber is used. Aluminum has low density and good processing performance, which helps to reduce weight and energy consumption; carbon fiber has high strength and corrosion resistance, which enhances structural strength and rigidity. This composite structure not only improves the stability of the machine body, but also optimizes thermal management to ensure stable operation in different temperature environments. In the moving part 3 of the device, rubber is selected as the material to reduce damage to the pipeline during movement.

[0047] Fan blades: Made of titanium alloy, which is characterized by high strength, is not easily deformed or broken during long-term use, is lightweight, and has good wear resistance and heat resistance.

[0048] In this invention, by changing the direction of the air vent 5 through the viewing window, the airflow direction is guided to control the movement of the fan blades. This allows the probe robot to slow down or return when it encounters an insurmountable obstacle, which is achieved by adjusting the airflow.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
