[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0043] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0044] Reference Figure 1-9 A power pipeline corridor inspection device according to this implementation scheme is described.

[0045] like Figure 1 As shown, the device includes a guide rail 1 , in which a cavity 9 with an opening is formed, and in which a patrol camera assembly 2 movable on the guide rail 1 is arranged.

[0046] like Figure 2 and 3 As shown, in this embodiment, an upper track plate 3 and a lower track plate 4 are arranged at the upper and lower positions of the inner wall surface of the guide rail 1, and an inner inclined surface 5 is formed on the lower track plate 4. A mobile connecting frame is arranged on the inspection camera assembly 2, and the mobile connecting frame includes a first mobile connecting frame and a second mobile connecting frame. The first mobile connecting frame can be moved on the upper track plate 3, and the second mobile connecting frame can be moved on the lower track plate 4. A telescopic adjustment member 7 is connected between the first mobile connecting frame and the second mobile connecting frame. The telescopic adjustment member 7 is an electric telescopic rod for adjusting the distance between the first mobile connecting frame and the second mobile connecting frame.

[0047] Among them, when the telescopic adjustment member 7 is pushed forward, the second movable connecting frame is attached to the lower track plate 4, and the first movable connecting frame is separated from the upper track plate 3; when the adjustment member 7 is retracted, the first movable connecting frame is attached to the upper track plate 3, and the second movable connecting frame is separated from the lower track plate 4.

[0048] During implementation, the second mobile connecting frame is overlapped on the lower track plate 4. The telescopic adjustment member 7 advances, at which time, the distance between the first mobile connecting frame and the second mobile connecting frame increases, so that the first mobile connecting frame is separated from the upper track plate 3, and the second mobile connecting frame drives the inspection camera assembly 2 to move. When the lower track plate 4 is rusted or foreign matter and impurities affect the movement of the second mobile connecting frame, the telescopic adjustment member 7 retracts to reduce the distance between the first mobile connecting frame and the second mobile connecting frame. At this time, the first mobile connecting frame is overlapped on the upper track plate 3, and continues to retract to separate the second mobile connecting frame from the lower track plate 4. At this time, the first mobile connecting frame drives the inspection camera assembly 2 to move.

[0049] Specifically, the first movable connecting frame includes a first support frame 6, and the second movable connecting frame includes a second support frame 8. Both the first support frame 6 and the second support frame 8 are provided with a moving component 10, so that the first support frame 6 and the second support frame 8 can be moved on the upper track plate 3 and the lower track plate 4 respectively.

[0050] like Figure 4 and 5 As shown, the first support frame 6 and the second support frame 8 both include a left plate 13 and a right plate 15, an intermediate body 14, a folding connecting frame and a cylinder 16. The left plate 13 and the right plate 15 are respectively arranged on both sides of the intermediate body 14; the folding connecting frame is connected between the left plate 13 and the right plate 15 and the intermediate body 14; when the left plate 13 and the right plate 15 are connected to the intermediate body 14, the folding connecting frame is connected to both sides, and the two folding connecting frames are W-shaped and M-shaped in the top view projection. The cylinder 16 is arranged on the left plate 13 and the right plate 15, and the moving assembly 10 is movably connected to both ends of the cylinder 16 through a movable hinge 17.

[0051] like Figure 4-8 As shown, the folding connecting frame includes a first connecting rod 11 and a second connecting rod 12 movably connected to each other. The first connecting rod 11 and the second connecting rod 12 are movably connected between the left plate 13 and the middle body 14, or movably connected between the right plate 15 and the middle body 14.

[0052] like Figure 6-8 As shown, a side of the left panel 13 close to the intermediate body 14 forms a fitting surface A131; the two side surfaces of the intermediate body 14 form a fitting surface B141; a side of the right panel 15 close to the intermediate body 14 forms a fitting surface C151; in the top view projection, the two ends of the left panel 13 and / or the right panel 15 can be close to or away from the intermediate body 14 through a folding connecting frame.

[0053] The fitting surface A131 on the side of the left panel 13, the fitting surface C151 on the side of the right panel 15, and the fitting surfaces B141 on both sides of the intermediate body 14 are all inclined surfaces arranged opposite to each other, and an angle α is formed between the two inclined surfaces, 90°<α<180°, specifically between 120° and 160°. The fitting surface A131 on the side of the left panel 13, the fitting surface C151 on the side of the right panel 15, and the fitting surfaces B141 on both sides of the intermediate body 14 are all arcs.

[0054] like Figure 8As shown, in the specific implementation process, the guide rail 1 has a straight section and a bending section. When the inspection camera assembly 2 moves to the bending section, the first support frame 6 and the second support frame 8 will bend and deform to ensure smooth passage through the bending section. Specifically, the curvature of the inner and outer sides of the bending section is different. At this time, the first support frame 6 and the second support frame 8 are automatically deformed by the bending section. During the deformation, the first connecting rod 11 and the second connecting rod 12 close to the inner side of the bending section are compressed and folded, so that one end of the left plate 13 and the right plate 15 are close to one end of the intermediate body 14; the first connecting rod 11 and the second connecting rod 12 close to the outer side of the bending section are stretched, so that the other end of the left plate 13 and the right plate 15 are away from one end of the intermediate body 14. The multi-section (left plate 13, intermediate body 1 and right plate 15) structure of linkage is adopted, so that when the inspection camera assembly 2 moves to the bending section, the first support frame 6 and the second support frame 8 are bent and deformed to pass smoothly.

[0055] like Fig. 9 As shown, the moving assembly 10 includes a housing 101, a groove 102, an active member and a servo motor 103 and a track guide 105, and the active member moves on the track guide 105. The groove 102 is formed at the bottom of the housing 101; the servo motor 103 is fixed to the housing 101 to drive the active member to rotate. In one embodiment, the active member includes a driving roller 104, which is rotatably connected in the groove 102, and the track guide 105 includes a rack, and the driving roller 104 is meshed and connected with the track guide 105. In another embodiment, the active member includes a roller, and the track guide 105 includes a track groove, and the roller is rotatably connected in the track groove.

[0056] Working principle: The second mobile connecting frame is overlapped on the lower track plate 4 to drive the inspection camera assembly 2 to move. When the lower track plate 4 is corroded or foreign matter and impurities affect the movement of the second mobile connecting frame, the telescopic adjustment member 7 retracts to reduce the distance between the first mobile connecting frame and the second mobile connecting frame. At this time, the first mobile connecting frame is overlapped on the upper track plate 3 and continues to retract to make the second mobile connecting frame detach from the lower track plate 4. At this time, the first mobile connecting frame works to drive the inspection camera assembly 2 to move. The first mobile connecting frame and the second mobile connecting frame are used alternately to ensure that the inspection camera assembly 2 can move normally and ensure the inspection process of the power corridor.

[0057] When the first mobile connecting frame and the second mobile connecting frame move to the bending section of the track 1, the first connecting rod 11 and the second connecting rod 12 close to the inner side of the bending section are compressed and folded, so that one end of the left plate 13 and the right plate 15 are close to one end of the intermediate body 14; the first connecting rod 11 and the second connecting rod 12 close to the outer side of the bending section are stretched, so that the other end of the left plate 13 and the right plate 15 are away from one end of the intermediate body 14. When the inspection camera assembly 2 moves to the bending section, the first support frame 6 and the second support frame 8 are bent and deformed to pass smoothly.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
