DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0018] Example: Figure 1-4 As shown, the utility model provides a detection device for a high-temperature resistant power cable, comprising a detection box 1, wherein both ends of the detection box 1 are penetrated with a feed port 11, one end of the interior of the detection box 1 is installed with a sleeve 12, and a ring-shaped heating tube 13 is fixedly installed on the inner wall of the sleeve 12, and a horizontal plate 2 is provided at the end of the interior of the detection box 1 away from the sleeve 12, and an extrusion plate 21 is fixedly provided on the opposite side of the two horizontal plates 2, and a vertically arranged first tooth plate 22 is respectively inserted at both ends of the two horizontal plates 2, and a first gear 23 is meshed with each other at the opposite ends of the two adjacent first tooth plates 22, and a rotating shaft 24 is fixed at the center of the first gear 23. The rotating shaft 24 is rotatably arranged on the detection box 1. On the inner wall of the testing box 1, one of the rotating shafts 24 passes through the testing box 1 and is fixed with a second gear 25. A second tooth plate 26 is meshed below the second gear 25. A vertically arranged movable plate 3 is fixed at the center of the lower surface of the second tooth plate 26. Movable grooves 31 are penetrated at the upper and lower ends of the movable plate 3. A push block 32 is movably inserted into the movable groove 31. A rotating plate 33 is fixed on the end of the push block 32 away from the testing box 1, and a rotating rod 34 is fixed on the end of the rotating plate 33 away from the rotating plate 33. A vertical partition 14 is fixed between the sleeve 12 and the extrusion plate 21 inside the testing box 1. The partition 14 separates the high-temperature resistance test and the pressure test to prevent the high temperature generated by the heating tube 13 from affecting the surrounding area.

[0019] A fixing frame 35 is fixed to the outer wall of the detection box 1 near the rotating rod 34, and the rotating rod 34 passes through the fixing frame 35. A support rod 36 is fixed to the side wall of the movable plate 3, and the support rod 36 can pass through the fixing frame 35. The fixing frame 35 supports the movable plate 3 and the rotating rod 34 so that they can work stably.

[0020] The two ends of the outer wall of the detection box 1 are located on both sides of the feed port 11, and a vertically arranged vertical plate 4 is fixedly provided. A driving roller 41 is rotatably provided at the upper and lower parts of the feed port 11 between the two adjacent vertical plates 4. A driving shaft 42 is fixed at both ends of the driving roller 41. The driving shaft 42 is rotatably provided on the vertical plate 4, wherein two adjacent driving shafts 42 are located on the same vertical plate 4 and are connected by two meshing connecting gears 43. The driving roller 41 cooperates with the two meshing connecting gears 43 to make the two driving rollers 41 rotate toward each other, thereby driving the cable to gradually move into the detection box 1 for detection; One of the drive shafts 42 at both ends of the detection box 1 is connected to the rotating rod 34 through a belt 45. By setting the belt 45, when the drive shaft 42 drives the roller 41 to drive the cable to move, the rotating rod 34 can also be driven to rotate, so that the extrusion plate 21 can work, thereby increasing the linkage of the device; one of the drive shafts 42 ends away from the belt 45 is provided with a drive motor 44 connected, and the output end of the drive motor 44 is coaxially fixed on the drive shaft 42. The provided drive motor 44 can provide power for the operation of the device, thereby facilitating operation by the staff.

[0021] Vertical rods 37 are movably inserted at both ends of the horizontal plate 2. The upper and lower ends of the vertical rods 37 are fixedly set on the inner wall of the detection box 1. The vertical rods 37 support the horizontal plate 2 when it moves, thereby ensuring that the horizontal plate 2 can move up and down stably.

[0022] Working principle: When in use, the driving motor 44 cooperates with the two meshing connecting gears 43 to directly drive the two driving rollers 41 to rotate in opposite directions. At this time, the two driving rollers 41 rotating in opposite directions will drive the drivable cable to gradually move into the detection box 1 for detection. At this time, the cable gradually moving into the sleeve 12 will be heated by the heating tube 13 to reach the threshold required by the current cable. As the driving roller 41 drives the cable to continue to move, it will enter between the two extrusion plates 21. At this time, the belt 45 can drive the rotating rod 34 to rotate. At this time, the rotating rod 34 will drive the rotating plate 33 to rotate, and the push block 32 at the end of the rotating plate 33 will gradually move from one end of the movable groove 31 to the other end. At this time, the pushing block 32 will push the moving plate 3 to move back and forth continuously. At this time, the second tooth plate 26 fixed on the top of the moving plate 3 will drive the second gear 25 to rotate back and forth repeatedly. The second gear 25 will drive the rotating shaft 24 to drive the first gear 23 to rotate back and forth continuously. Since the first gear 23 will rotate back and forth continuously, it can drive the first tooth plate 22 diagonally meshed on the first gear 23 to move toward and away from each other at the same time, and can drive the cross plate 2 to push the extrusion plate 21 to squeeze the cable moved into the detection box 1, generating pressure on its surface, so that when the detection is within the threshold set for the cable, the pressure detection can ensure that the surface is used normally, and then it is discharged from the detection box 1 at the feed port 11 for collection.

[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
