[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 3 , Figure 4 As shown, it is a structural diagram of an intelligent pipeline aging detection device provided by an embodiment of the present invention, comprising a horizontal column 1, a circular ring 4 is rotatably installed on the surface of the horizontal column 1, a plurality of groups of vertical plates 5 arranged opposite to each other are fixedly installed on the surface of the circular ring 4, a cleaning brush 6 and a detector 7 are arranged between the two groups of vertical plates 5 arranged opposite to each other, a walking mechanism 2 is arranged at both ends of the horizontal column 1, and the walking mechanism 2 includes a supporting component 21 and an adjusting component 22, the supporting component 21 is located at both ends of the horizontal column 1, the supporting component 21 is used to support and position the horizontal column 1 in the inner cavity of the pipeline, the adjusting component 22 is connected to the supporting component 21, and the adjusting component 22 supports the horizontal column 1 in the inner cavity of pipelines of different calibers by cooperating with the supporting component 21 Support and positioning, a rotating component 9 cooperating with the ring 4 is arranged in the horizontal column 1, and the rotating component 9 is used to control the ring 4 to rotate on the surface of the horizontal column 1, and a control mechanism 8 cooperating with the cleaning brush 6 and the detector 7 is arranged between the two relatively distributed groups of vertical plates 5, and the control mechanism 8 includes a positioning component 81 and a protective component 82, the positioning component 81 is located on the surface of the vertical plate 5 and is connected with the cleaning brush 6 and the detector 7, the positioning component 81 is used to adjust the relative position of the cleaning brush 6 and the detector 7 between the two groups of vertical plates 5, the protective component 82 is located and connected to the two groups of vertical plates 5, when the cleaning brush 6 cleans the inner wall of the pipeline, the protective component 82 seals and protects the detector 7 by cooperating with the positioning component 81.

[0024] When in use, the cross column 1 is placed in the inner cavity of the pipeline, and the adjustment component 22 cooperates with the support component 21 to support and position the cross column 1 in the inner cavity of the pipeline, and the cross column 1 can be controlled to move in the inner cavity of the pipeline. After the cross column 1 moves to a suitable position and needs to detect the inner wall of the pipeline, the positioning component 81 first adjusts the position of the cleaning brush 6 and the detector 7 so that the cleaning brush 6 contacts the inner wall of the pipeline. At this time, the detector 7 is between the cleaning brush 6 and the ring 4, and the rotating component 9 drives the ring 4 to rotate on the surface of the cross column 1, and the ring 4 drives the cleaning brush 6 By synchronous rotation, the cleaning brush 6 can efficiently clean the inner wall of the pipe. During the cleaning process, the protective component 82 seals and protects the detector 7. The protective component 82 can effectively prevent the cleaned impurities from falling on the surface of the detector 7. After the cleaning is completed, the positioning component 81 adjusts the position of the cleaning brush 6 and the detector 7 so that the detector 7 and the cleaning brush 6 are swapped. At this time, the protective component 82 releases the sealing protection of the detector 7, and the ring 4 drives the detector 7 to detect the inner wall of the ring. The detector 7 can accurately detect the inner wall of the ring.

[0025] like Figure 1 , Figure 3 As shown, as a preferred embodiment of the present invention, the support assembly 21 includes a plurality of groups of support rods 211 distributed in a ring and rotatably installed at both ends of the cross column 1, and a roller 212 is rotatably installed at one end of the support rod 211 away from the cross column 1, and the roller 212 is connected to a first motor 213.

[0026] When in use, the adjustment component 22 controls the support rod 211 to rotate at both ends of the horizontal column 1, so that the roller 212 at the end of the support rod 211 fits against the inner wall of the pipe. At this time, multiple groups of support rods 211 and rollers 212 cooperate with each other to support and position the horizontal column 1 in the inner cavity of the pipe. The first motor 213 controls the rotation of the roller 212, thereby pushing the horizontal column 1 to move in the inner cavity of the pipe.

[0027] like Figure 1 , Figure 3As shown, as a preferred embodiment of the present invention, the adjusting component 22 includes a fixed column 221 fixedly installed at both ends of the horizontal column 1, a telescopic cavity 222 is opened inside the fixed column 221, and a connecting groove 224 connected to the telescopic cavity 222 is opened inward on the surface of the fixed column 221, a sliding block 223 is slidably installed in the telescopic cavity 222, a threaded rod 226 is rotatably installed in the telescopic cavity 222, the threaded rod 226 is spirally connected to the sliding block 223, a push-pull rod 225 is rotatably installed on the side wall of the sliding block 223, one end of the push-pull rod 225 away from the sliding block 223 passes through the connecting groove 224 and extends to the outside of the fixed column 221 and is rotatably connected to the side wall of the support rod 211, one end of the threaded rod 226 extends to the outside of the fixed column 221 and is fixedly installed with a control disk 227, and a limiting portion 3 is provided on the surface of the control disk 227.

[0028] During use, after the cross column 1 is placed in the inner cavity of the pipeline, the handheld control disk 227 is rotated, and the control disk 227 drives the threaded rod 226 to rotate. The threaded rod 226 pushes the sliding block 223 to move in the telescopic cavity 222. The sliding block 223 cooperates with the push-pull rod 225 to push the support rod 211 to rotate at both ends of the cross column 1, so that the roller 212 at the end of the support rod 211 fits against the inner wall of the pipeline. After the support rod 211 rotates to a suitable position, the limit part 3 fixes the position of the control disk 227 at the end of the fixed column 221.

[0029] like Figure 1 , Figure 3 As shown, as a preferred embodiment of the present invention, the limiting portion 3 includes a plurality of groups of first screw holes 31 distributed in an annular shape and opened on the surface of the control disk 227, a second screw hole 33 is opened on the side wall of the fixing column 221, and a positioning bolt 32 that cooperates with the second screw hole 33 is installed in the first screw hole 31.

[0030] After the support rod 211 is rotated to a suitable position, the positioning bolt 32 is installed in the first screw hole 31 at the corresponding position on the surface of the control disk 227. The positioning bolt 32 is further screwed into the second screw hole 33, and the position of the control disk 227 can be fixed at the end of the fixing column 221.

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the positioning assembly 81 includes a rotating column 811 rotatably installed between two groups of vertical plates 5, a supporting plate 812 is fixedly installed on the surface of the rotating column 811, the cleaning brush 6 is arranged on one side of the supporting plate 812, and the detector 7 is arranged on the other side of the supporting plate 812, one end of the rotating column 811 extends to the outside of the vertical plate 5 and is connected to a second motor 813.

[0032] When in use, the supporting plate 812 supports and positions the cleaning brush 6 and the detector 7. Initially, the cleaning brush 6 is on the outer side of the supporting plate 812, and the detector 7 is on the inner side of the supporting plate 812. At this time, the ring 4 drives the cleaning brush 6 to rotate, and the impurities attached to the inner wall of the pipe can be efficiently cleaned. When the inner wall of the pipe needs to be inspected, the second motor 813 drives the supporting plate 812 to rotate one hundred and eighty degrees. At this time, the cleaning brush 6 rotates to the inner side of the supporting plate 812, and the detector 7 rotates to the outer side of the supporting plate 812. At this time, the cleaning brush 6 is released from the cleaning state, and the detector 7 can efficiently inspect the inner wall of the pipe.

[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the protective component 82 includes a fixed column 821 fixedly installed between two groups of vertical plates 5 and located below the supporting plate 812, and two groups of relatively distributed storage chambers 822 are opened inside the fixed column 821, and a winding roller 823 is rotatably installed in the storage chamber 822, and winding springs are respectively provided at both ends of the winding roller 823. A protective belt 824 is wound on the surface of the winding roller 823, and one end of the protective belt 824 extends away from the winding roller 823 to the outside of the fixed column 821 and is fixedly installed with a positioning plate 825, and the positioning plate 825 is made of magnetic material, and the side wall of the supporting plate 812 is provided with an electromagnetic sheet 826 that cooperates with the positioning plate 825.

[0034] Initially, the protective belt 824 is entirely in the storage cavity 822. When the detector 7 needs to be sealed and protected, the second motor 813 drives the carrying plate 812 to rotate between the two groups of vertical plates 5, and the carrying plate 812 drives the electromagnetic sheet 826 to rotate synchronously. When the electromagnetic sheet 826 on one side of the carrying plate 812 rotates to the surface of the fixed column 821, the electromagnetic sheet 826 is connected to the positioning plate 825 on one side of the fixed column 821 through magnetic attraction to form a whole. The second motor 813 drives the carrying plate 812 to rotate in the opposite direction, thereby causing the electromagnetic sheet 826 on the other side of the carrying plate 812 to rotate to the surface of the fixed column 821, and the electromagnetic sheet 826 is connected to the positioning plate 825 on the other side of the surface of the fixed column 822 to form a whole. When the carrying plate 812 rotates to a horizontal state, the positioning plate 825 rotates synchronously and then pulls out the protective belt 824 synchronously. The two groups of protective belts 824 are respectively located on both sides of the detector 7. When the cleaning brush 6 cleans the inner wall of the pipeline, the protective belt 824 can perform sealing protection on the detector 7. When cleaning is completed and inspection is required, the electromagnetic sheet 826 is controlled to be powered off. At this time, the winding roller 823 rolls up the protective belt 824 into the storage chamber 822, and the second motor 813 drives the supporting plate 812 to rotate so that the detector 7 rotates to the outer side of the supporting plate 812. The detector 7 can efficiently detect the inner wall of the pipeline.

[0035] like Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the rotating component 9 includes a control cavity 91 opened inside the cross column 1, a connecting groove 94 connected to the control cavity 91 is opened inwardly on the surface of the cross column 1, a gear ring 95 is provided on the inner wall of the circular ring 4, a third motor 92 is fixedly installed in the control cavity 91, a transmission gear disc 93 is fixedly installed on the output shaft of the third motor 92, and the transmission gear disc 93 passes through the connecting groove 94 and is meshed with the gear ring 95.

[0036] When in use, the third motor 92 drives the transmission gear disc 93 to rotate, and the transmission gear disc 93 is meshed with the gear ring 95 for transmission, which can drive the ring 4 to rotate on the surface of the horizontal column 1.

[0037] The working principle of the present invention is: when in use, the cross column 1 is placed in the inner cavity of the pipeline, and the hand-held control disk 227 is rotated. The control disk 227 drives the threaded rod 226 to rotate, and the threaded rod 226 pushes the sliding block 223 to move in the telescopic cavity 222. The sliding block 223 cooperates with the push-pull rod 225 to push the support rod 211 to rotate at both ends of the cross column 1, so that the roller 212 at the end of the support rod 211 fits with the inner wall of the pipeline, and the first motor 213 controls the roller 212 to rotate, thereby pushing the cross column 1 to move in the inner cavity of the pipeline. After the support rod 211 rotates to a suitable position, the second motor 813 drives the supporting plate 812 to rotate between the two groups of vertical plates 5, and the supporting plate 812 drives the electromagnetic sheet 826 to rotate synchronously. When the electromagnetic sheet 826 on one side of the supporting plate 812 rotates to the surface of the fixed column 821, the electromagnetic sheet 826 is connected to the positioning plate 825 on one side of the fixed column 821 through magnetic attraction to form a whole. The second motor 813 drives the supporting plate 812 to rotate in the opposite direction, so that the electromagnetic sheet 826 on the other side of the supporting plate 812 rotates to the surface of the fixed column 821, and the electromagnetic sheet 826 is connected to the positioning plate 825 on the other side of the surface of the fixed column 822 to form a whole. When the supporting plate 812 rotates to a horizontal state, the positioning plate 825 rotates synchronously and then pulls out the protective belt 824 synchronously. The two groups of protective belts 824 are respectively located on both sides of the detector 7, and the protective belt 824 can seal and protect the detector 7. The third motor 92 drives the transmission gear disc 93 to rotate, and the transmission gear disc 93 and the gear ring 95 are meshed and driven, which can drive the ring 4 to rotate on the surface of the horizontal column 1. At this time, the ring 4 drives the cleaning brush 6 to rotate, and the impurities attached to the inner wall of the pipeline can be efficiently cleaned. When the inner wall of the pipeline needs to be inspected, the electromagnetic sheet 826 is controlled to be powered off, and the winding roller 823 rewinds the protective belt 824 into the storage chamber 822. The second motor 813 drives the bearing plate 812 to rotate so that the detector 7 rotates to the outer side of the bearing plate 812, and the detector 7 can efficiently detect the inner wall of the pipeline.

[0038] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
