Description

Technical Field

[0001] This utility model relates to the field of wire take-up components, specifically a wire take-up component for lightning protection detection equipment. Background Technology

[0002] One of the important tasks in lightning protection testing is measuring the grounding resistance of the lightning protection device or the equipotential transition resistance between the device and other equipment to determine whether it is qualified. Both of these measurements require specialized test leads, typically running from one platform on the roof to another, involving reeling in and reeling in the lead, and even on the same large rooftop platform.

[0003] Currently, take-up assemblies are commonly used to wind up cables for lightning protection testing. Due to the nature of the lightning protection testing process, existing cables inevitably come into contact with the ground during use, resulting in dust and sewage contaminants on the cable surface. Dust and sewage can corrode and contaminate the cable sheath, thus affecting the cable's lifespan. Furthermore, existing take-up rollers are typically installed using bolts, requiring the tightening of multiple bolts for installation and removal, leading to low winding efficiency when winding multiple cables. Therefore, a take-up assembly for lightning protection testing equipment is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a take-up assembly for lightning protection testing equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a take-up assembly for a lightning protection testing device, comprising a base plate, a support plate one mounted on one upper side of the base plate, a support plate two movably mounted on the upper upper side of the base plate one side, support shafts rotatably connected to the opposing surfaces of support plate one and support plate two, a rotating block mounted on one end of each support shaft, a square groove provided on the upper end of each rotating block, a sliding groove provided on one side of each square groove, a limit plate movably mounted inside the sliding groove, a take-up roller placed between the two support shafts, a square block mounted on both ends of each take-up roller, the square block located inside the square groove, an mounting block mounted on the upper upper side of the base plate in front of the take-up roller, an mounting groove provided on the mounting block, and a cleaning component installed inside the mounting groove.

[0006] Preferably, L-shaped plates are symmetrically installed on the upper end of the bottom plate on one side of the support plate one, and movable blocks are installed below the front and rear ends of the support plate two. The two movable blocks are respectively located below the two L-shaped plates. Movable grooves are provided on the L-shaped plates. Limiting bolts are installed inside the movable grooves at the upper end of the L-shaped plates through screw holes. A contact plate is threadedly connected to the surface of the limiting bolts. The lower end of the contact plate is connected to the upper end of the L-shaped plates.

[0007] Preferably, a movable rod is installed at one end of the sliding groove through a through hole, a limiting plate is installed at one end of the movable rod, a fixed plate is provided at one end of the movable rod, and a spring is installed on the surface of the movable rod between one end of the fixed plate and one end of the rotating block.

[0008] Preferably, a guide rod is installed between the support plate one and the support plate two in front of the take-up roller through a through hole, and a wire guide wheel is installed on the surface of the guide rod.

[0009] Preferably, the cleaning assembly includes a mounting plate, rotating wheels, rotating shafts, pulleys, belt strips, a motor, and a cleaning cloth. Two mounting plates are mounted inside the mounting slot via a frame. Four rotating shafts are rotatably mounted between the two mounting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This lightning protection testing equipment uses a cable take-up assembly. By setting up a cleaning assembly, the cable is placed between two cleaning cloths in the cleaning assembly. When the cable is taken up, it will move, and the cable will come into contact with the surface of the cleaning cloth, thus cleaning the surface of the cable. As the cable moves, the motor can drive the two cleaning cloths to rotate through the rotating wheel, so that the surface of the cleaning cloths can be used alternately to ensure effective wiping of the cleaning cloths.

[0014] 2. This lightning protection testing equipment uses a take-up assembly. By setting up structures such as rotating blocks, limiting plates, and square blocks, the limiting plate is moved by sliding to move away from above the square slot, allowing the square blocks at both ends of the take-up roller to be placed into the square slot. The limiting plate then resets to fix the square blocks, completing the installation of the take-up roller. To disassemble, simply move the limiting plate away from above the square blocks to remove the take-up roller, effectively improving the efficiency of installation and disassembly of the take-up roller.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 4As shown, the take-up assembly for the lightning protection testing equipment in this embodiment includes a base plate 1. A support plate 2 is installed on one side of the upper end of the base plate 1. A support plate 3 is movably installed on the upper end of the base plate 1 on the side of the support plate 2. The support plate 3 can be moved to facilitate adjustment according to the length of the take-up roller 9, and is suitable for take-up rollers 9 of various lengths. Support shafts 4 are rotatably connected to the opposite surfaces of the support plate 2 and the support plate 3. A rotating block 5 is installed at one end of each support shaft 4. A square groove 6 is provided on the upper end of each rotating block 5. A sliding groove 7 is provided on one side of the square groove 6. A limiting plate 8 is movably installed inside the groove 7. A take-up roller 9 is placed between the two support shafts 4. A square block 10 is installed at both ends of the take-up roller 9. The square block 10 is located inside the square groove 6. The limiting plate 8 is used to limit the square block 10 by sliding, so as to realize the installation of the take-up roller 9 and effectively improve the installation and disassembly efficiency of the take-up roller 9. An installation block 11 is installed on the upper end of the base plate 1 in front of the take-up roller 9. An installation groove 12 is provided on the installation block 11. A cleaning component is installed inside the installation groove 12. The cleaning component is used to clean the surface of the cable.

[0023] Specifically, L-shaped plates 14 are symmetrically installed on the upper end of the base plate 1 on one side of support plate 2. Movable blocks 15 are installed at the lower ends of support plate 3. The two movable blocks 15 are located below the two L-shaped plates 14 respectively. Movable grooves 16 are provided on the L-shaped plates 14. Limiting bolts 17 are installed inside the movable grooves 16 at the upper end of the L-shaped plates 14 through screw holes. Contact plates 18 are threadedly connected to the surface of the limiting bolts 17. The lower end of the contact plate 18 and the upper end of the L-shaped plates 14 are connected. By moving support plate 2, support plate 2 drives the two movable blocks 15 to move below the L-shaped plates 14, thereby guiding support plate 2. By rotating the limiting bolts 17, the contact plates 18 are moved down to contact the L-shaped plates 14, thereby fixing the position of support plate 2.

[0024] Furthermore, a moving rod 19 is installed at one end of the sliding groove 7 through a through hole, and a limiting plate 8 is installed at one end of the moving rod 19. A fixing plate 20 is located at one end of the moving rod 19. A spring spring 21 is installed on the surface of the moving rod 19 between one end of the fixing plate 20 and one end of the rotating block 5. In its natural state, the limiting plate 8 is located above the square groove 6. When the square block 10 needs to be placed into the square groove 6, the limiting plate 8 is pushed. The limiting plate 8 stretches the spring spring 21 through the moving rod 19 and the fixing plate 20, so that the limiting plate 8 can automatically fix the square block 10.

[0025] Furthermore, a guide rod 22 is installed between the support plate 2 and the support plate 3 in front of the take-up roller 9 through a through hole. A wire guide wheel 27 is installed on the surface of the guide rod 22. When the support plate 3 is adjusted, the guide rod 22 can be moved. The working principle of the wire guide wheel 27 is a known existing technology, so it will not be explained in detail.

[0026] Furthermore, the cleaning assembly includes a mounting plate 1301, rotating wheels 1302, rotating shafts 1303, pulleys 1304, belts 1305, a motor 1306, and a cleaning cloth 1307. Two mounting plates 1301 are mounted inside the mounting slot 12 via a frame. Four rotating shafts 1303 are rotatably mounted between the two mounting plates 1301. Rotating wheels 1302 are mounted on the surface of each rotating shaft 1303. Cleaning cloths 1307 are detachably mounted on the surfaces of the two upper rotating wheels 1302 and the two lower rotating wheels 1302. One end of each of the two middle rotating shafts 1303 passes through a mounting plate 1301, and a pulley 1304 is mounted on one end of each of the two middle rotating shafts 1303. A belt is mounted on the surface of each of the two pulleys 1304. The strip 1305 has a motor 1306 installed at one end of the mounting slot 12. The output end of the motor 1306 is connected to a pulley 1304. By passing the cable between two cleaning cloths 1307, the cable contacts the surface of the cleaning cloths 1307 when it is wound up, allowing the cleaning cloths 1307 to wipe the surface of the cable and clean it. When the motor 1306 rotates, it drives the rotating wheel 1302 to rotate, causing the cleaning cloths 1307 to rotate and contact the unused cleaning cloths 1307 with the surface of the cable, ensuring effective wiping by the cleaning cloths 1307. The cleaning cloths 1307 are installed on the surface of the two rotating wheels 1302 by Velcro or other means, making it easy to remove them for cleaning later.

[0027] Furthermore, a fixing rod 23 is installed inside the mounting slot 12 in front of a cleaning cloth 1307. A measuring wheel 24 is installed on the surface of the fixing rod 23. A magnetoelectric sensor 25 is installed on one side of the measuring wheel 24 via a frame. The magnetoelectric sensor 25 is used to detect the number of rotations of the measuring wheel 24. When the cable is wound up, the cable drives the measuring wheel 24 to rotate. The magnetoelectric sensor 25 can detect the number of rotations of the measuring wheel 24. The length of the cable passing through the measuring wheel 24 can be calculated. When the cable reaches a certain length, the motor 1306 is controlled to rotate, so that the surface of the unused cleaning cloth 1307 comes into contact with the cable, realizing the alternating use of the surface of the cleaning cloth 1307. The principle of the magnetoelectric sensor 25 detecting the number of rotations is based on the principle of magnetoelectric induction, which is a known existing technology and will not be described in detail.

[0028] Furthermore, a motor 26 is mounted on the surface of the support plate 2 away from the support shaft 4. The output end of the motor 26 is connected to the support shaft 4. The motor 26 drives the support shaft 4 to rotate, which can realize the automatic winding of the take-up roller 9. The motor 26 is connected to a forward and reverse circuit, which can rotate in both directions.

[0029] The usage method of this embodiment is as follows: When using the lightning protection testing equipment, the take-up roller 9 is installed. By moving the second support plate 3, the distance between the first support plate 2 and the second support plate 3 is made appropriate. The square blocks 10 at both ends of the take-up roller 9 are placed into the square grooves 6 on the rotating block 5, and the square blocks 10 are limited by the limiting plate 8. Then, the limiting bolt 17 is rotated to move down, so that the contact plate 18 and the L-shaped plate 14 contact each other, thereby fixing the second support plate 3 and completing the installation of the take-up roller 9. Then, the cable is passed between the measuring wheel 24, the two cleaning cloths 1307 and the cable guide wheel 27, and one end of the cable is wound around the take-up roller 9. Then, the second motor 26 is controlled to rotate, and the second motor 26 drives the take-up roller 9 to rotate, thereby winding the cable. During this process, the cable moves and comes into contact with the surfaces of the two cleaning cloths 1307. The two cleaning cloths 1307 wipe the surface of the cable to clean it. At the same time, the cable moves and drives the measuring wheel 24 to rotate. When the measuring wheel 24 rotates, the magnetoelectric sensor 25 detects the number of rotations of the measuring wheel 24. The length of the cable passing through the measuring wheel 24 can be calculated. When the specified length is reached, the control motor 1306 drives the two cleaning cloths 1307 to rotate, so that the surface of the unused cleaning cloth 1307 comes into contact with the cable. This achieves the alternating use of the surface of the cleaning cloth 1307, effectively ensuring the cleaning effect of the cleaning cloth 1307. After the cable winding is completed, the moving limit plate 8 removes the winding roller 9, and then the cleaning cloth 1307 can be removed for cleaning.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
