In this embodiment, the cleaning mechanism 8 further includes a driving wheel 802 disposed on the left side of the natural gas pipeline 3, the opposite faces of the two self-locking connection rings 5 are fixedly connected with connection plates 17, the opposite faces of the two connection plates 17 are fixedly connected with a same U-shaped mounting block 16, the upper side of the U-shaped mounting block 16 is rotationally connected with the lower side of the driving wheel 802, a transmission hole is formed in the upper side of the U-shaped mounting block 16, the inner wall of the transmission hole is rotationally connected with a transmission shaft, the top end of the transmission shaft is fixedly connected with the lower side of the driving wheel 802, and the surface of the transmission shaft is fixedly connected with a driving wheel 18.
By arranging the driving wheel 18 to drive the driving wheel 802 to rotate, the connecting plate 17 is connected with the self-locking connecting ring 5 through bolts, and the surface of the driving wheel 18 can be attached to the demonstration sleeve through rotating the bolts.
In this embodiment, the lower side of the driving wheel 18 is rotatably connected with the inner wall of the U-shaped mounting block 16, the lower side of the mounting table 804 is rotatably connected with a driven wheel, the upper side of the driven wheel is fixedly connected with a connecting shaft, the top end of the connecting shaft penetrates through the upper side of the mounting table 804 and is fixedly connected with the lower side of the rotating disc 805, the surface of the driving wheel 802 is lapped with a driving belt 803, and the driving wheel 802 is in driving connection with the driven wheel through the driving belt 803.
By providing the transmission belt 803 to link the driving wheel 802 and the driven wheel, the driving wheel 18 rotates under the action of friction force when the traction assembly 6 operates, and the rotating disc 805 rotates with the rotation of the driving wheel 18 under the driving of the transmission belt 803.
The working principle of the invention is as follows:
When the device is used, the self-locking connecting ring 5 is firstly taken down from the carrier 7 and sleeved on a natural gas pipe, the image recognition control module 19 is started, the image recognition control module 19 comprises a camera and a controller, the camera can reflect the condition of a pipeline to the controller, the controller can perform preliminary judgment on the condition of the pipeline, for example, the greasy dirt or dust condition of the pipeline is preliminarily judged, the controller is connected with the electric telescopic rod 605, a motor in the electric drive track 609 and ultrasonic detection equipment, then the cleaning time and the cleaning position of the device are continuously controlled, the electric telescopic rod 605 is started and regulated, and when the output end of the electric telescopic rod 605 is regulated to move, the first connecting block 603 is driven to move horizontally, and then the electric drive track 609 is driven to move until the surface of the electric drive track 609 abuts against the surface of the natural gas pipe;
Then, the electric drive caterpillar 609 and the ultrasonic detection equipment are started, and the carrier 7 is pushed to enable the carrier 7 to keep up with the motion of the traction assembly 6, the electric drive caterpillar 609 moves to drive the mounting plate 4 to move, the ultrasonic detection equipment continuously detects forwards, along with the operation of the electric drive caterpillar 609, the driving wheel 18 rotates under the action of friction force, the driving wheel 18 rotates to drive the transmission shaft to rotate, the transmission shaft rotates to drive the driving wheel 802 to rotate, the driving wheel 802 rotates to drive the driven wheel to rotate under the driving of the transmission belt 803, the driven wheel rotates to drive the rotating disc 805 to rotate, the rotating disc 805 rotates to drive the constraint rod 809, the constraint rod 809 moves to push the swinging strip 807 to swing back and forth, the swinging strip 807 moves to drive the transmission gear 810 to do back and forth, the transmission rack 812 moves to drive the pushing plate 816 to move, the pushing rod 815 moves to drive the piston 814 to do back and forth, when the piston 814 moves rightwards due to the limitation of the water sucking one-way valve 819 and the water outlet one-way valve 821, the cleaning agent in the tank 801 is sucked into the sleeve 813, when the piston 814 moves leftwards, the cleaning agent is injected into the sleeve 821 through the water sucking pipe, the sleeve is accurately, and the dust is sucked through the water outlet pipe 819 and the water outlet pipe 821 is confined by the water outlet pipe, and the water flow is accurately detected through the water outlet pipe, and the self-locking device is well, and the dust is well-sucked through the sleeve pipe is well, and the dust is well-sucked through the water, finally, the dust is well is automatically washed.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
