Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0042] A remotely controlled pipeline cleaning robot, such as Figure 1 , Figure 2 As shown, including,

[0043] The robot body 1 receives and transmits external control signals;

[0044] The power unit 2 is provided on the robot body 1 and drives the robot body 1 to move in the pipeline to be cleaned. The power unit 2 includes:

[0045] Leg 21;

[0046] A moving assembly 22, rotatably connected to the supporting leg 21;

[0047] A first pneumatic telescopic rod 23, rotatably connected to the legs 21 and the robot body 1;

[0048] The cleaning part 3 is connected to the power part 2, and the cleaning part 3 includes:

[0049] Cleaning base 31;

[0050] The cleaning brush 32 is retractably disposed on the peripheral side of the cleaning base 31 .

[0051] Specifically, the utility model provides a remote-controllable pipe cleaning robot, which consists of a robot body 1, a power unit 2, and a cleaning unit 3. The robot body 1 is used to receive and transmit external control signals to achieve a remote control effect. The power unit 2 is used to flexibly drive the robot body 1 to move in the pipe to be cleaned. The retractable function of the cleaning unit 3 makes it more convenient to carry, reduces the size, and improves the cleaning effect and work efficiency.

[0052] In a preferred embodiment, referring to Figure 1 , Figure 5 , Figure 6 , the opening and closing angle formed by the moving component 22 and the axis of the pipeline to be cleaned can be adjusted, and the opening and closing angle controls the moving speed of the robot body 1;

[0053] A pressure sensor for providing feedback on the degree of fit with the pipe to be cleaned is provided in the moving assembly 22;

[0054] The power unit 2 further includes:

[0055] A leg support 24, connecting the robot body 1 and the leg 21;

[0056] A second pneumatic telescopic rod for controlling the opening and closing angle is provided in the leg support 24;

[0057] The moving assembly 22 is provided with universal wheels.

[0058] Specifically, the robot body 1 controls the leg seat 24 and the first pneumatic telescopic rod 23 to extend and shorten to control the opening and closing angle of the leg 21. At the same time, the moving component 22 contains a pressure sensor, and the sensor feedback is used to confirm whether the moving component 22 is tightly fitted to the pipe wall.

[0059] More specifically, the wheels on the mobile assembly 22 are universal wheels that can rotate in a small space. When the wheels are at an angle to the pipeline axis, the entire robot will rotate forward, and the rotation forward rate can be controlled by adjusting the angle between the wheels and the pipeline axis.

[0060] In a preferred embodiment, referring to Figure 3 , Figure 4 A spring buckle 311 for fixing the cleaning brush 32 and a motor 33 elastically connected to the cleaning brush 32 are provided in the cleaning base 31 .

[0061] Specifically, in this embodiment, the spring 312 is used to realize the elastic connection between the motor 33 and the cleaning brush 32. When the cleaning robot is not in use, all the cleaning brushes 32 are pushed into the cleaning base 31, at which time the spring 312 is in a compressed state, and the spring buckle 311 pops out to clamp the cleaning brush 32. When in use, the robot body 1 transmits a signal, so that the spring buckle 311 is retracted, the spring 312 is extended, and the cleaning brush 32 pops out to fit tightly against the inner wall of the pipe.

[0062] In a preferred embodiment, referring to Figure 1 , Figure 7 The robot body 1 is provided with an extension part 4 at one end away from the cleaning part 3, and the extension part 4 includes:

[0063] Spring steel ring 41;

[0064] A collecting device 42, wrapped around a spring steel ring 41;

[0065] A traction rope 43, connecting the spring steel ring 41 and the robot body 1;

[0066] The diameter of the spring steel ring 41 is equal to the diameter of the pipe to be cleaned;

[0067] The collecting device 42 is a trawl net or a cloth bag.

[0068] Specifically, a support net or a bag can be hung at the tail of the robot to take the large particles of dirt brushed off by the brush head out of the pipeline, without the need for secondary cleaning, thereby improving work efficiency and cleaning effect. The diameter of the spring steel ring 41 is equal to the diameter of the pipeline to be cleaned, and the collection device 42 is wrapped on it to form a device for capturing large particles of dirt. When the robot moves in the pipeline, it can effectively collect and fix large particles of dirt, such as debris, residues, etc., to prevent them from being scattered back into the pipeline.

[0069] More specifically, the traction rope 43 connects the spring steel ring 41 and the robot body 1, making it easy to install and remove the collection device 42. The operator can easily replace or clean the collection device when necessary without making major adjustments or maintenance to the entire robot.

[0070] In a preferred embodiment, the robot body 1 is provided with:

[0071] A controller for receiving an external control signal;

[0072] The position sensor is connected to the controller to feedback the position information.

[0073] Specifically, the robot body 1 is capable of receiving and transmitting external control signals, so that the operator can remotely control the robot to perform cleaning tasks, thereby reducing the need for human intervention, reducing the risk of personnel being exposed to dangerous environments, and improving the safety and efficiency of cleaning operations.

[0074] In the first embodiment, referring to Figures 1 to 7 The pipeline cleaning robot is composed of a cleaning structure, a power structure, a control robot, and expansion accessories. The cleaning structure is composed of a cleaning brush 32, a cleaning structure base, and a motor 33. The cleaning structure base contains a spring buckle 311 and a spring 312.

[0075] When not in use, all cleaning brushes 32 are pushed inwardly toward the cleaning structure base, at which time the spring 312 is in a compressed state, and the spring buckle 311 pops out to clamp the cleaning brush 32. When in use, the spring buckle 311 is retracted inwardly and the spring 312 is extended outwardly by controlling the robot signal transmission, and the cleaning brush 32 pops out and fits tightly against the inner wall of the pipe.

[0076] The power structure consists of a leg seat 24, a leg 21, a first pneumatic telescopic rod 23, and a wheel group. The wheel group is the mobile component 22. The control robot controls the leg seat 24 (containing the second pneumatic telescopic rod) and the first pneumatic telescopic rod 23 to extend and shorten to control the opening and closing angle of the leg 24. At the same time, the wheel group contains a pressure sensor, and the sensor feedback is used to confirm whether the wheel group is tightly fitted to the pipe wall. The wheel group is a universal wheel and can rotate. When the wheel is at an angle to the pipe axis, the entire robot will rotate forward. By adjusting the angle between the wheel and the pipe axis, the rotation forward rate can be controlled.

[0077] The extended accessories can hang a trawl net or a cloth bag, and the outer edge of the trawl net or the cloth bag is wrapped on a ring made of spring steel with the same diameter as the pipe, and is hung on the robot with a traction rope 43.

[0078] Specifically, the device can be folded and is more convenient to carry; the pneumatic telescopic rod pushes the legs 24, so that the wheels can fit closely against the pipe wall; the universal joint wheels can change the direction and speed of travel, and when the wheels are at an angle to the pipe axis, even if the brush head does not rotate, the body of the robot will drive the brush head to rotate and move forward; the spring 312 inside the brush head can make the brush head fit closely against the pipe wall, making cleaning more convenient; a support net or cloth bag can be hung at the tail of the robot to take large particles of dirt brushed off by the brush head out of the pipe.

[0079] In summary, the present application provides a remotely controllable pipeline cleaning robot, which is composed of a robot body 1, a power unit 2, and a cleaning unit 3. The setting of the power unit 2 enables the robot body 1 to move in the pipeline to be cleaned. The combination of the legs 21 and the moving assembly 22 provides a stable support and rotation capability, and the rotating connection of the first pneumatic telescopic rod 23 increases the operational flexibility of the robot in the pipeline, so that the robot can effectively adapt to the tortuosity and complex structure of the pipeline and complete the cleaning task. The cleaning unit 3 can ensure the comprehensive cleaning of the pipeline, and the scalability of the cleaning brush enables it to adapt to different pipeline sizes and shapes, and effectively clean various parts of the pipeline, including curves and corners. The scalability of the cleaning brush 32 not only increases the comprehensiveness of cleaning, but also improves the cleaning efficiency. It can be adjusted according to the specific situation of the pipeline to ensure that every place can be effectively cleaned, thereby reducing the waste of cleaning time and resources.
