Description

Technical Field

[0001] The utility model relates to the field of insulator detection equipment, in particular to an insulator detection device for an outdoor power system. Background Art

[0002] Outdoor power systems refer to systems that transmit electrical energy from power stations to outdoor users, including transmission, transformation, distribution, and consumption. Insulators are essential components of outdoor power systems. Therefore, before insulators are put into use in outdoor power systems, they must be inspected using an insulator testing device to ensure that there are no quality issues. Only then can they be put into use.

[0003] The patent document with the publication number "CN219349038U" discloses "a safety detection device for insulators, comprising a base, wherein a guide rail is fixedly mounted on the upper end of the base, and the insulator body is placed on the supporting roller to support the two ends of the insulator body, and the clamping plate is clamped and fixed to the two ends of the insulator body by moving the displacement seat, thereby improving the stability of the clamping and facilitating the rotation of the insulator body by the rotating motor, so that the visual inspection unit scans and inspects the insulator body to detect surface defects and roundness errors of the insulator body, and the spacing between the two movable tables is used to facilitate the adaptation of insulators of different sizes. Although it has the effect of "conveniently adapting to insulator bodies of different sizes and improving practicality", the height of the supporting roller that lifts the insulator cannot be adjusted. When clamping and fixing insulators of different diameters, it is difficult to ensure that the axis of the insulator coincides with the axis of the supporting roller. Therefore, when the insulator rotates, the supporting roller is likely to interfere with the outside of the insulator, resulting in the insulator being unable to rotate, affecting the test results. In addition, during the test process, both the insulator and the visual inspection unit are immovable. Therefore, when the insulators are of different lengths, the visual inspection unit is difficult to detect different positions of the insulator due to angle problems, resulting in inaccurate test results.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] The lifting mechanism 7 includes a roller frame 701, two lifting rollers 702 are movably installed on the top of the roller frame 701, two support rods 703 are movably installed on the bottom of the roller frame 701, and a sliding base 704 is movably installed on the bottom end of the support rod 703. A double-threaded rod 705 is connected to the two sliding bases 704 by the front end thread. A handwheel 2 707 is fixedly installed on one end of the double-threaded rod 705, and the outer ring of the double-threaded rod 705 is provided with two sections of threads of the same length and opposite directions. The brackets of the two double-threaded rods 705 are respectively fixedly connected to the fixed carrying frame 2 and the movable carrying frame 6.

[0035] Specifically, when inspecting the insulator, the hand wheel 14 is turned to drive the single-thread screw rod 13 to rotate, thereby adjusting the distance between the movable carrying frame 6 and the fixed carrying frame 2, so as to adjust the spacing between the two driving mechanisms 8 and the spacing between the two lifting mechanisms 7 according to the length of the insulator, so as to facilitate clamping of insulators of different lengths. After the adjustment is completed, the insulator is placed on the top of the lifting roller 702, and the hand wheel 2 707 is turned to drive the double-thread screw rod 705 to rotate, thereby adjusting the spacing between the two sliding bases 704. The roller frame 701 is lifted by the movable sliding base 704 in cooperation with the support rod 703, thereby adjusting the height of the lifting roller 702, so as to facilitate lifting insulators of different diameters. Then, the hand wheel 14 is turned again to drive the single-thread screw rod 13 to rotate, adjust the position of the driving mechanism 8 at the top of the movable carrying frame 6, and cooperate with another driving mechanism 8 to clamp the insulator. Then, the inspection mechanism 10 is started to scan and inspect the insulator to detect surface defects and appearance defects of the insulator.

[0036] A limiting slide bar 706 is slidably connected between the two sliding bases 704 at the rear end, and the limiting slide bar 706 is fixedly connected to the bracket of the double-threaded screw rod 705. Two positioning grooves 72 are provided at the bottom of the front and rear ends of the roller frame 701. Two positioning laser pens 71 are fixedly installed at the bottom of the front end of one of the roller frames 701, and the positioning laser pen 71 and the positioning groove 72 are located in the same straight line.

[0037] Specifically, when adjusting the lifting mechanism 7, the positioning laser pen 71 is started, and the height of the lifting roller 702 in one of the lifting mechanisms 7 is adjusted first. During the adjustment process, the sliding base 704 is limited by the limiting slide bar 706 to prevent the rotation of the double-threaded screw 705 from causing the movement of the sliding base 704. When adjusting the other lifting mechanism 7, by observing the laser point shot by the positioning laser pen 71, when the laser point hits the positioning groove 72, it means that the lifting rollers 702 in the two lifting mechanisms 7 are at the same height, avoiding the different heights of the lifting rollers 702 causing the lifted insulator to tilt, resulting in the insulator being unable to rotate during the detection process, affecting the detection process.

[0038] A slide rod 5 is provided on both sides of the single-thread screw rod 3, and the two ends of the slide rod 5 are fixedly connected to the fixed mounting frame 2 and the bracket of the single-thread screw rod 3 respectively, and the movable mounting frame 6 is slidably connected to the slide rod 5.

[0039] Specifically, when adjusting the position of the movable mounting frame 6, the stability of the movable mounting frame 6 is improved by cooperating with the single-thread screw 3 and the slide bar 5. At the same time, the movable mounting frame 6 is limited by the slide bar 5 to prevent the rotation of the single-thread screw 3 from causing the movable mounting frame 6 to rotate.

[0040] The driving mechanism 8 includes a fixed base 801, and the two fixed bases 801 are fixedly connected to the movable mounting frame 6 and the fixed mounting frame 2 respectively. A motor 802 is fixedly installed through the front and rear ends of the fixed base 801, and the output shaft of the motor 802 is fixedly connected to the chuck 803.

[0041] Specifically, when adjusting the distance between the two driving mechanisms 8 by adjusting the movable mounting frame 6, two clamping plates 803 are used to clamp the two ends of the insulator to fix the insulator. After starting the motor 802, the clamping plates 803 are driven to rotate by the motor 802, thereby driving the insulator to rotate, so that the detection mechanism 10 can scan and detect different positions of the insulator.

[0042] The detection mechanism 10 includes a single-thread screw rod 1002, the bracket of which is fixedly connected to the top frame 9, the external thread of the single-thread screw rod 1002 is connected to the slider 1001, the end of the single-thread screw rod 1002 is installed with a motor 1004, and a slide rod 1003 is provided on both sides of the single-thread screw rod 1002.

[0043] Slide rod 2 1003 is fixedly connected to single-threaded screw rod 2 1002, slider 1001 is slidingly connected to slide rod 2 1003, the output shaft of motor 2 1004 is fixedly connected to single-threaded screw rod 2 1002, the housing of motor 2 1004 is fixedly connected to the bracket of single-threaded screw rod 2 1002, and a visual detection unit 1005 is fixedly installed in the center of the bottom end of slider 1001.

[0044] Specifically, when inspecting the insulator, the motor 2 1004 is started to drive the single-threaded screw 2 1002 to rotate, thereby driving the slider 1001 and the visual inspection unit 1005 to move, and the stability of the slider 1001 during the movement is improved by the slide bar 2 1003, so that different positions of insulators of different lengths can be inspected by the moving visual inspection unit 1005, thereby avoiding omissions during the inspection process and improving the inspection accuracy.

[0045] It should be noted that the present invention is an insulator detection device for an outdoor power system. When in use, first, the hand wheel 4 is turned to drive the single-thread screw rod 3 to rotate, thereby adjusting the distance between the movable carrier 6 and the fixed carrier 2, so as to facilitate the adjustment of the spacing between the two driving mechanisms 8 and the spacing between the two lifting mechanisms 7 according to the length of the insulator, so as to facilitate the clamping of insulators of different lengths. After the adjustment is completed, the insulator is placed on the top of the lifting roller 702, and then the hand wheel 2 707 is turned to drive the double-thread screw rod 705 to rotate, thereby adjusting the spacing between the two sliding bases 704, and the roller frame 701 is lifted by the movable sliding base 704 in cooperation with the support rod 703, thereby adjusting the height of the lifting roller 702, so as to facilitate the lifting of insulators of different diameters. Then, the hand wheel 4 is turned again to drive the single-thread screw rod 3 to rotate, adjust the position of the driving mechanism 8 on the top of the movable carrier 6, and cooperate with the other driving mechanism 8 to clamp the insulator.

[0046] When adjusting the lifting mechanism 7, the positioning laser pen 71 is activated to first adjust the height of the lifting roller 702 in one of the lifting mechanisms 7. During the adjustment process, the sliding base 704 is limited by the limiting slide bar 706 to prevent the sliding base 704 from moving due to the rotation of the double-threaded screw 705. When adjusting the other lifting mechanism 7, the laser point projected by the positioning laser pen 71 is observed. When the laser point hits the positioning groove 72, it indicates that the lifting rollers 702 in the two lifting mechanisms 7 are at the same height, thereby preventing the lifting rollers 702 from tilting due to different heights, which would cause the insulator being lifted to be unable to rotate during the detection process, affecting the detection process.

[0047] After completing the clamping and fixing of the insulator, the detection mechanism 10 and the driving mechanism 8 are started to scan and detect the insulator to detect the surface defects and appearance defects of the insulator. After starting the motor 1 802, the chuck 803 is driven to rotate by the motor 1 802, thereby driving the insulator to rotate. At the same time, the motor 2 1004 is started to drive the single-threaded screw 2 1002 to rotate, thereby driving the slider 1001 and the visual inspection unit 1005 to move, and the stability of the slider 1001 during the movement is improved by the slide bar 2 1003, so as to facilitate the detection of different positions of insulators of different lengths through the moving visual inspection unit 1005, avoid omissions during the detection process, and improve the detection accuracy.
