Technical Field

[0001] The invention relates to the technical field of robots, and in particular to a pipeline cleaning mechanism for a pipe diameter measuring robot. Background Art

[0002] Boiler "four-tube" leakage is the main cause of various unplanned shutdowns of thermal power generating units, accounting for 50% to 60% of the unplanned shutdown accidents of the units. It is a major problem that plagues thermal power generation companies and poses a great threat to the safe operation of thermal power plants.

[0003] At present, when the existing pipeline cleaning device is in use, the staff mainly uses the cleaning device to clean the pipeline. During the cleaning, a large amount of dust will be generated. This dust can easily enter the lungs of the staff along with the air. Secondly, when cleaning the pipeline, since the pipelines are placed side by side, the position of the cleaning device needs to be constantly adjusted during the cleaning of the pipeline to clean the dust on the outside of the pipeline. This process not only takes a lot of time and energy, but also requires the efficiency of pipeline cleaning. For this reason, we propose a pipeline cleaning mechanism for a pipe diameter measuring robot. Summary of the invention

[0011] Preferably, a nozzle is installed at the front end of the front connecting plate, and the nozzle is connected to a water tank installed on the top of the front connecting plate through a pipeline.

[0012] Preferably, the self-locking motor is electrically connected to a battery installed inside the rear connection plate via a wire.

[0013] Preferably, two ends of the support core are respectively provided with a docking pin and a docking socket which can be plugged into each other, and both ends of the support core are fixed to the opposite side of the front connecting plate and the rear connecting plate through bearings.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Reference Figure 2 and Figure 3As shown, a pipe cleaning mechanism for a pipe diameter measuring robot comprises a support mechanism and a support rod 5 installed on the top of the support mechanism, a front connecting plate 6 is installed at the front end of the support rod 5 by bolts, and a rear connecting plate 7 is arranged at the front end of the front connecting plate 6, wherein:

[0035] The support rod 5 is connected to the rear connecting plate 7 through a telescopic rod 18 installed at the center of its front end, and the output shaft of the self-locking motor 8 installed inside the rear connecting plate 7 is connected to the telescopic end of the telescopic rod 18. Semicircular grooves are provided on the opposite sides of the front connecting plate 6 and the rear connecting plate 7, and an arc-shaped support core 9 is installed on the inner wall of the groove. The outside of the support core 9 is covered with an outer sleeve 14, and the outside of the outer sleeve 14 is bonded with bristles.

[0036] Reference Figure 1 As shown, the support mechanism includes a support frame 1, two sets of mutually parallel guide rails 2 are installed on the top of the support frame 1, and a support base 3 is slidably installed on the top of the guide rail 2, and the support base 3 is connected to the support rod 5 through a mechanical arm 4 installed on the top thereof.

[0037] Reference Figure 1 A motor is installed at the bottom of the support seat 3, and the motor is meshed with a toothed belt installed on the outside of the guide rail 2 through a gear installed on its output shaft.

[0038] Reference Figure 5 As shown, an airbag tube 15 is installed inside the outer sleeve 14, and the airbag tube 15 is connected to the valve core installed outside the outer sleeve 14 through a pipeline.

[0039] Reference Figure 4 As shown, a nozzle 13 is installed at the front end of the front connecting plate 6, and the nozzle 13 is connected to a water tank 12 installed on the top of the front connecting plate 6 through a pipeline.

[0040] Reference Figure 3 The self-locking motor 8 is electrically connected to the battery installed inside the rear connection plate 7 through a wire.

[0041] Reference Figure 6 , Figure 7 and Figure 8 As shown, the two ends of the support core 9 are respectively installed with a docking pin 16 and a docking socket 17 that can be plugged into each other, and the two ends of the support core 9 are fixed to the opposite side of the front connecting plate 6 and the rear connecting plate 7 through bearings.

[0042] Reference Figure 6 Magnets are installed inside the docking pin 16 and the docking socket 17, and a slot that can be plugged into the docking pin 16 is opened at the front end of the docking socket 17.

[0043] Reference Figure 4As shown, an external gear 10 corresponding to the support core 9 is installed inside the front connecting plate 6, and the outside of the external gear 10 is linked to the outside of the support core 9 through an external connecting belt 11, and the external gear 10 is connected to the output shaft of the driving motor installed inside the front connecting plate 6.

[0044] When in use, the motor is first used to drive the gear installed on its output shaft to rotate. Since the gear is meshed with the toothed belt installed on the outside of the guide rail 2, the support seat 3 can be controlled to move back and forth along the extension direction of the guide rail 2 when the gear rotates. When it moves to the specified position, the motor is controlled to stop rotating, and then the self-locking motor 8 located inside the rear connecting plate 7 is controlled to rotate, so that the rear connecting plate 7 and the front connecting plate 6 are vertically separated. After adjustment, the front connecting plate 6 is pushed toward the pipeline direction by the mechanical arm 4. When the rear connecting plate 7 moves to the rear of the pipeline, the self-locking motor 8 is controlled to drive the rear connecting plate 7 to rotate 90°, forming a Figure 2 The shape shown, after completion, the telescopic rod 18 is controlled to retract, so that the rear connecting plate 7 moves toward the front connecting plate 6, so that the front connecting plate 6 and the rear connecting plate 7 are docked with each other. During docking, the docking pin 16 located on the surface of the rear connecting plate 7 is correspondingly plugged into the docking socket 17 located on the surface of the front connecting plate 6, so that the two supporting cores 9 in opposite positions are connected end to end in sequence to form a closed loop shape to cover the pipeline. After completion, the driving motor is controlled to drive the outer gear 10 to rotate. Since the outer connecting belt 11 outside the outer gear 10 connects it with the supporting core 9, when the outer gear 10 rotates, it can drive the supporting core 9 to rotate. Since the two groups of supporting cores 9 are connected end to end, when the supporting core 9 located inside the front connecting plate 6 rotates, the supporting core 9 located inside the rear connecting plate 7 can be mobilized to rotate together. When the supporting core 9 rotates, the outer sleeve 14 outside the supporting core 9 rotates together, so the bristles outside the outer sleeve 14 will rotate together when the outer sleeve 14 rotates, thereby cleaning the pipeline surface located inside the supporting core 9.

[0045] While cleaning, the nozzle 13 sprays the cleaning liquid inside the water tank 12 to the outside of the pipe, which facilitates the cleaning of the pipe by the external bristles of the outer sleeve 14, thereby improving the cleaning efficiency.

[0046] Since the air bag tube 15 is arranged inside the outer sleeve 14, the bristles outside the outer sleeve 14 can be squeezed toward the pipe direction, so that the bristles fit tightly with the outside of the pipe.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
