[0030] Figures 1 to 4 The utility model provides a pipeline internal cleanliness detection robot. As can be seen from the figure, the utility model provides a pipeline internal cleanliness detection robot, including a shell 100, a printed circuit board and a connector; the shell 100 has a receiving cavity 110 and an opening 120 located at the top of the shell 100 and connected to the receiving cavity 110, and the bottom wall of the receiving cavity 110 has a threaded blind hole; the printed circuit board is located in the receiving cavity 110 and has a through hole; the side wall of the connector has a threaded section, and the connector can extend into the through hole and be screwed into the threaded blind hole.

[0031] In specific implementation, the design of this pipeline internal cleanliness detection robot effectively solves the problem in the prior art that water in the pipeline easily enters the housing 100 through the threaded hole through some key improvements. A housing 110 is provided inside the housing 100 of the robot for accommodating a printed circuit board and other electronic components. An opening 120 is provided at the top of the housing 100, which is connected to the housing 110 for easy installation and maintenance. A threaded blind hole is designed on the bottom wall instead of a threaded hole that passes through the bottom of the housing 100, so that even if the robot is working in the pipeline, the water in the pipeline will not enter the housing 110 through this hole. The printed circuit board is located in the housing 110 and is connected to the connector through a perforation. The side wall of the connector has a threaded section that can extend into the perforation and be screwed into the threaded blind hole to fix the printed circuit board. This design not only improves the sealing and waterproof performance of the robot, but also protects the internal electronic components, especially the printed circuit board, from being damaged by contact with water, thereby improving the reliability and service life of the robot.

[0032] According to one embodiment of the present invention, the connecting piece is a threaded rivet.

[0033] In specific implementation, the threaded rivet can be an existing one, and the design of this threaded rivet allows it to extend directly into the perforation of the printed circuit board and be screwed with the threaded blind hole on the bottom wall of the shell 100. By using threaded rivets, the assembly process of the robot is simpler and faster, while enhancing the firmness of the connection. The use of threaded rivets also means that there is no need to make through threaded holes on the shell 100, thereby avoiding the risk of water entering the accommodating chamber 110 through the threaded holes, further improving the waterproof performance and overall sealing of the robot. This improvement not only protects the electronic components inside the robot, especially the sensitive printed circuit board, from damage due to contact with moisture, but also makes the robot more adaptable to work in a humid or watery environment, improving its reliability and durability in practical applications.

[0034] According to an embodiment of the present invention, a cover plate 200 is further included, and the cover plate 200 is disposed to cover the opening 120 .

[0035] In specific implementation, the main function of the cover plate 200 is to cover the opening 120 at the top of the housing 100, thereby forming a sealed environment. In this way, the cover plate 200 can not only prevent water, dust or other impurities in the pipeline from entering the accommodating cavity 110 through the opening 120, protecting the internal printed circuit board and other electronic components from damage, but also reduce the interference of external factors on the internal environment of the robot during the movement or operation of the robot.

[0036] According to an embodiment of the present invention, the cover plate 200 is a structural member made of a transparent material.

[0037] In a specific implementation, the cover plate 200 is made of a transparent material. Such a transparent cover plate 200 can not only maintain the sealing of the opening 120 of the robot housing 100 to prevent the intrusion of foreign substances, but also its transparency provides convenience for the maintenance and inspection of the robot. The transparent cover plate 200 allows the operator or technician to directly observe the status of the internal printed circuit board and other components without opening the robot, so as to quickly evaluate the working condition of the robot or perform fault diagnosis.

[0038] According to an embodiment of the present invention, a driving unit 300 is further included, which is disposed in the accommodating cavity 110 and is used to drive the pipeline internal cleanliness detection robot to move forward.

[0039] In specific implementation, this drive unit 300 is cleverly arranged in the housing chamber 110 of the robot. Its main function is to provide power for the robot so that it can move autonomously in the pipeline. With the built-in drive unit 300, the robot can move more flexibly inside the pipeline and perform cleanliness detection tasks without external traction or pushing. This design not only improves the autonomy and maneuverability of the robot, but also reduces its dependence on the external environment, allowing the robot to adapt to more complex and changeable pipeline environments. The addition of the drive unit 300 enables the robot to complete detection tasks more efficiently, while also reducing the labor intensity of the operator. In addition, since the drive unit 300 is located in the housing chamber 110, it is protected by the housing 100 together with the electronic components of the robot, which further improves the stability and reliability of the robot in harsh environments.

[0040] According to an embodiment of the present invention, a moving unit 400 is further included, which is rotatably disposed on the housing 100 and connected to the output end of the driving unit 300 .

[0041] In a specific implementation, the mobile unit 400 can be flexibly mounted on the housing 100 and connected to the output end of the driving unit 300. The design of the mobile unit 400 allows the robot to move in the pipeline as required, thereby achieving travel in the pipeline.

[0042] In this embodiment, the moving unit 400 includes a first moving mechanism 410 and a second moving mechanism 420; the first moving mechanism 410 is rotatably disposed on one side of the shell 100 along its width direction W; the second moving mechanism 420 is rotatably disposed on the other side of the shell 100 along its width direction W; the driving unit 300 connects the first moving mechanism 410 and the second moving mechanism 420.

[0043] According to one embodiment of the utility model, the driving unit 300 includes a first motor 310 and a second motor 520; the output shaft of the first motor 310 is connected to the first moving mechanism 410; the output shaft of the second motor 520 is connected to the second moving mechanism 420; the first motor 310 and the second motor 520 are arranged along the length direction L of the shell 100.

[0044] In specific implementation, the drive unit 300 is composed of two motors: a first motor 310 and a second motor 520. The two motors are responsible for driving the two moving mechanisms in the mobile unit 400, namely the first moving mechanism 410 and the second moving mechanism 420. The output shaft of the first motor 310 is connected to the first moving mechanism 410, while the output shaft of the second motor 520 is connected to the second moving mechanism 420, ensuring the precise and independent control of the robot in the pipeline. This design allows the robot to achieve more complex and flexible movement through the cooperation of the two motors. For example, when the two motors rotate at the same speed, the robot can move forward or backward in a straight line; when one motor rotates and the other motor does not rotate or rotates at different speeds, the robot can turn or rotate. In addition, the first motor 310 and the second motor 520 are arranged along the length direction L of the shell 100. This layout helps to maintain the center of gravity balance of the robot, and may also help to optimize the space utilization inside the robot, making the robot more compact.

[0045] According to one embodiment of the utility model, the first moving mechanism 410 and the second moving mechanism 420 respectively include a moving wheel 401 and a track 402; the moving wheel 401 is rotatably arranged on the shell 100; the track 402 is arranged around the moving wheel 401; the output shaft of the first motor 310 is connected to the moving wheel 401 of the first moving mechanism 410; the output shaft of the second motor 520 is connected to the moving wheel 401 of the second moving mechanism 420.

[0046] In specific implementation, this design allows the track 402 to provide additional grip and stability when the robot moves in the pipeline, especially on rough or uneven pipeline surfaces. The rotation ability of the moving wheel 401 combined with the stability of the track 402 provides the robot with a wider range of adaptability. The output shaft of the first motor 310 is connected to the moving wheel 401 of the first moving mechanism 410, and the output shaft of the second motor 520 is connected to the moving wheel 401 of the second moving mechanism 420. This means that the two motors can independently control the moving wheels 401 of their respective moving mechanisms, thereby achieving more sophisticated control, including but not limited to actions such as linear movement, steering or rotation.

[0047] According to one embodiment of the utility model, it also includes a camera 500, multiple infrared lamps 600, a light sensor 700 and a controller; the camera 500 is installed at the front end of the shell 100, and multiple infrared lamps 600 are installed on both sides of the camera 500; the light sensor 700 is installed at the front end of the shell 100 and is located above the camera 500; the controller is connected to the camera 500, the multiple infrared lamps 600 and the light sensor 700.

[0048] In specific implementation, the camera 500 is installed at the front end of the robot housing 100, which enables it to capture images inside the pipeline and provide visual data for cleanliness detection. In order to clearly capture images in an environment with insufficient light, multiple infrared lamps 600 are installed on both sides of the width direction W of the camera 500. These infrared lamps 600 can provide necessary lighting inside the dark pipeline to help the camera 500 capture clear images. The light sensor 700 is also installed at the front end of the housing 100 and is located above the camera 500. The function of the light sensor 700 is to detect the light intensity inside the pipeline, so that the robot can adjust the brightness of the infrared lamp 600 according to the actual light conditions to obtain the best image quality. The controller is the brain of the entire system, which is responsible for coordinating the work of the camera 500, the infrared lamp 600 and the light sensor 700 to ensure that the robot can respond appropriately according to environmental changes. The controller may also be responsible for processing and analyzing image data, as well as communicating with the operator. Through the integration of these components, the robot can not only adapt to different lighting conditions, but also provide high-quality image data, thereby more accurately evaluating the cleanliness inside the pipeline. This design significantly improves the robot's intelligence level and detection efficiency, making it a powerful tool for pipeline maintenance and inspection.
