Description

Technical Field

[0001] The present invention relates to the technical field of pipeline cleaning, and in particular to a pipeline cleaning robot. Background Art

[0002] Pipeline robots play a vital role in the maintenance of modern industrial and urban infrastructure. They can go deep into narrow or difficult-to-reach pipelines to perform tasks instead of people, significantly improving the safety of operations and reducing the risks faced by workers. At present, pipeline robots are mainly used to check pipeline integrity, find leaks and blockages, and clean up blockages to ensure smooth pipeline operation. Because the diameters of pipelines are inconsistent, pipeline robots need to have the function of changing diameters to cope with pipelines of different diameters. In the prior art, pipeline robots usually require motor drive to achieve variable diameter adjustment, which not only increases the complexity and energy consumption of the system, but also leads to a large overall weight, affecting the operational flexibility in narrow or complex pipeline environments. At the same time, pipeline robots often cannot achieve independent variable diameter adjustment of the crawler feet, which limits their ability to work stably in pipelines with varying diameters, resulting in problems such as loose grip, unstable driving, and difficulty in climbing. Summary of the invention

The elastic member 6 is provided on the fixed rod 3 and is located on one side of the connecting rod 5. The moving mechanism 4 is suitable for driving the connecting rod 5 to rotate and slide one end of the connecting rod 5 along the fixed rod 3 toward the direction close to the elastic member 6 under external force.

[0047] Specifically, the side of the main machine 1 facing the inside of the pipeline is the front side, and a cleaning mechanism is provided on the front side, through which the blockage in the pipeline can be cleaned.

The locator is connected to the terminal signal to obtain the precise coordinate information of the location of the pipeline cleaning robot and transmit it to the terminal. Preferably, the visual recognition unit 17 is a camera device.

[0073] Specifically, the control device also includes a controller, and the locator is connected to the controller by signal. The locator can obtain the precise coordinate information of the location of the pipeline cleaning robot and transmit it to the controller. The control mainboard is connected to the controller by signal through the wireless transmission module, and the controller can obtain the control information and operation process of the control mainboard. The controller is provided with a display screen, and the control mainboard can transmit the image information data in front of the host 1 obtained by the visual recognition unit 17 to the controller, and the controller can display it on the display screen after processing the data. The wireless transmission module adopts a dual-mode redundant wireless communication mechanism, including Bluetooth wireless transmission and ESP-NOW self-organizing network technology. The Bluetooth wireless transmission uses the HC-05 Bluetooth module as a communication medium, receives information from the control mainboard in real time, and realizes data exchange with the control mainboard through serial communication, so as to realize fine control of the robot state; the ESP-NOW self-organizing network technology uses the ESP series chip as a communication medium, and can establish a point-to-point or point-to-multipoint communication link based on the unique mac address of the device when the Bluetooth network fails, so as to ensure effective data communication between the controller and the control mainboard.

[0074] The controller includes STM32F103C8T6 microcontroller, MPU6050 gyroscope, FLEX sensor curvature sensor, SU-03T voice module, TFT display and mobile phone. The gyroscope and curvature sensor can convert the curvature of the user's fingers and the change of the hand angle into the robot motor control signal, and use the body sensing technology to achieve fine control of the robot's movement and speed regulation. The controller uses the wireless transmission module to obtain the information sent by the control motherboard, and realizes the information display combined with audio and video and the remote control combined with body sensing and mobile devices.

[0075] It should be noted that, by controlling the mainboard to obtain data information, controlling the motion mechanism 4 to drive the host 1 to move forward or controlling the electric drill to clean the blockage in the pipeline, the pipeline cleaning robot can operate independently according to the situation in the pipeline, avoiding the process that requires continuous manual operation, reducing the difficulty of operation, and improving work efficiency.
