Description

Technical Field

[0001] The present invention relates to the technical field of grounding shielding clips, and specifically discloses an automatic tensioning grounding shielding clip. Background Art

[0002] A grounding shielding clip is a core connecting member used for grounding, fixing and shielding protection of cable shielding layers in power transmission lines and communication cable systems, which features excellent electrical conductivity, firm clamping, weather and corrosion resistance, and reliable insulation and shielding. It is widely applied in scenarios such as high-voltage power transmission, optical fiber communication, industrial wiring, transformer substations and outdoor cable erection, and is mainly used to realize reliable grounding of cable shielding layers, fix cable routing, shield electromagnetic interference and ensure line operation safety. Its clamping stability, grounding reliability and adaptability are directly related to the safe operation, service life and shielding effect of the cable system, making it an indispensable key component for outdoor cable laying and line safety protection.

[0003] As an upgraded type of grounding shielding clip, the automatic tensioning grounding shielding clip integrates core functions such as automatic tensioning, limit fixing, grounding and shielding, adapts to the long-term laying and dynamic working condition requirements of outdoor cables, can realize automatic cable tensioning, stable limiting, reliable grounding and shielding protection, is suitable for cable erection scenarios of different specifications and types, and is widely used in various outdoor cable erection and line operation and maintenance scenarios. It provides important support for the long-term safe, stable and orderly laying of cables, and is an important supporting component for ensuring the operation stability of the cable system and reducing operation and maintenance costs. In the actual process of outdoor cable erection and long-term operation, the stability of cable tensioning, the reliability of limit fixing and the cleaning and maintenance effect of the mounting frame directly affect line operation safety, equipment service life and operation and maintenance difficulty. At present, there are key problems to be solved urgently in the application process of shielding clips and mounting frame cleaning equipment supporting outdoor cable erection: the existing cable erection structure lacks automatic tensioning and limit fixing structures, and the cables are prone to slack after long-term use, and will frequently shake and swing under the action of wind force, which not only leads to unstable stress on the cables, but also easily aggravates cable wear, fatigue and aging, and affects line operation safety; at the same time, the traditional structure cannot effectively limit and lock the cables, the cables are still prone to displacement and offset after being tensioned, the positioning stability is poor, and it is difficult to ensure the long-term tensioned and orderly laying state of the cables; in addition, the traditional deicing and cleaning equipment for cable mounting frames has a single structure, no wind-linked power structure, and deicing and impurity removal need to rely on independent power components, resulting in high energy consumption and complex structure. Conventional equipment can only perform simple deicing, and lacks an integrated structure of impact ice breaking and brush cleaning, so that ice on the mounting frame is difficult to be completely removed, and fallen ice blocks, rainwater and sundries are easy to accumulate around the mounting frame and cannot be cleaned in time. Long-term accumulation of sundries and accumulated water is likely to cause corrosion of the mounting frame and repeated accumulation of ice, which further affects the operation stability of line equipment, resulting in high difficulty in operation and maintenance cleaning and poor operation effect. Therefore, an automatic tensioning grounding shielding clip is invented to address the above defects. Summary of the Invention

The first top shaft mounting frame is slidably installed on the inclined plate.

[0009] Furthermore, a positioning block mounting frame is fixedly installed at the end of the first top shaft mounting frame away from the cable mounting frame, a positioning shaft mounting frame is fixedly installed on the positioning block mounting frame, a driving rod mounting frame is slidably installed on the side of the movable frame mounting frame, a first movable shaft mounting frame is fixedly installed on the side of the driving rod mounting frame, and the outer surface of the first movable shaft mounting frame abuts against the outer surface of the positioning shaft mounting frame.

[0010] Furthermore, a third moving shaft mounting frame and a fourth moving shaft mounting frame are fixedly mounted on the side of the semi-ring mounting frame. The third and fourth moving shaft mounting frames are respectively fixedly connected to the drive rod mounting frame. A groove is provided on the semi-ring mounting frame, and a friction block mounting frame is slidably mounted in the groove. A second moving shaft mounting frame is fixedly mounted on the side of the friction block mounting frame away from the cable mounting frame. The second moving shaft mounting frame is fixedly connected to the drive rod mounting frame. A retaining ring mounting frame is fixedly mounted on the outer surface of the second moving shaft mounting frame. A third spring mounting frame is wound around the outer surface of the second moving shaft mounting frame. One end of the third spring mounting frame is fixedly mounted on the side of the retaining ring mounting frame, and the other end of the third spring mounting frame is fixedly mounted on the semi-ring mounting frame.

[0011] Furthermore, the cleaning component includes a transmission shaft mounting frame rotatably mounted on the lower side of the mounting plate mounting frame, a transmission belt mounting frame connected to the transmission shaft mounting frame, the transmission shaft mounting frame being connected to the rotating shaft mounting frame via the transmission belt mounting frame to form a belt drive, a rotating disk mounting frame being fixedly mounted at the lower end of the transmission shaft mounting frame, and a brush mounting frame being fixedly mounted at the end of the rotating disk mounting frame away from the transmission shaft mounting frame.

[0016] (2) The present invention provides a power source for the cleaning component and the striking component by rotating the fan blade and connecting it with the cleaning component and the striking component. The icy part near the mounting frame is struck by the impact shaft, and the ice block is cleaned by the brush. At the same time, the brush can also clean the rainwater and debris near the mounting frame, so as to avoid the accumulation of the cleaned ice block and rainwater debris near the mounting frame.

[0028] As mentioned in the background section, this application proposes an automatic tensioning grounding shield clamp.

A mounting frame 201 is slidably mounted on the inner wall of the protective shell 202. A spiral rod 501 is mounted on the protective shell, rotatably connected to the mounting frame 201. A handle 502 is fixedly mounted on the end of the spiral rod 501 away from the mounting frame 201. The spiral rod 501 and the protective shell 202 form a spiral engagement. The mounting frame 201 can be detached from the protective shell 202. Four movable frames 301 are slidably mounted on the mounting frame 201. A cable 101 is installed between the four movable frames 301. A tensioning assembly is installed between every two adjacent movable frames 301. The tensioning assembly and the cable... Cable 101 is connected, and each movable frame 301 is connected to a limiting half ring 314. Each limiting half ring 314 is connected to a tensioning component. Each movable frame 301 is fixedly installed with a fixing hook 322. The fixing hook 322 can limit the cable 101. The tensioning component includes two limiting shafts 302 fixedly installed on the mounting frame 201. Every two adjacent movable frames 301 are slidably installed on the outer surface of a limiting shaft 302. Two segments of first spring 303 are wound on the outer surface of each limiting shaft 302. One end of each segment of first spring 303 is fixedly installed on the mounting frame 201, and the other end of the first spring 303 is fixedly installed on the side of the movable frame 301.

[0030] As mentioned in the background section, this application proposes an automatic tensioning grounding shield clamp.

[0031] Appendix Figure 2 To the attached Figure 5 As shown, in a preferred embodiment, four mounting seats 323 are fixedly installed on the inner wall of the mounting block. A first connecting shaft 304 is fixedly installed on the side of each mounting seat 323. A fixing rod 305 is fixedly installed on the outer surface of the first connecting shaft 304. A sliding rod 306 is slidably installed between two fixing rods 305. A cantilever plate 307 is fixedly installed on each sliding rod 306. A first top shaft 308 is slidably installed on the cantilever plate 307. The end of the first top shaft 308 facing the cable 101 is hemispherical. A second spring 310 is wound around the outer surface of the first top shaft 308. One end of the second spring 310 is fixedly installed on the side of the cantilever plate 307, and the other end of the second spring 310 is fixedly installed on the outer surface of the first top shaft 308. The cantilever plate 307 is formed by a vertical plate and an inclined plate that are smoothly connected. The vertical plate is fixedly installed on the fixing rod 305, and the inclined plate is fixedly installed on the end of the vertical plate away from the fixing rod 305. The first top shaft 308 is slidably installed on the inclined plate.

[0032] As mentioned in the background section, this application proposes an automatic tensioning grounding shield clamp.

[0033] Appendix Figure 3To the attached Figure 5 As shown, in a preferred embodiment, a positioning block 315 is fixedly installed at the end of the first top shaft 308 away from the cable 101. A positioning shaft 316 is fixedly installed on the positioning block 315, and a retaining shaft 309 is fixedly installed on the positioning shaft 316. A driving rod 311 is slidably installed on the side of the moving frame 301. A first moving shaft 312 is fixedly installed on the side of the driving rod 311. The outer surface of the first moving shaft 312 abuts against the outer surface of the retaining shaft 309 and the outer surface of the positioning shaft 316, respectively. A third moving shaft 318 and a fourth moving shaft 321 are fixedly installed on the side of the limiting semi-ring 314. The third moving shaft 318 and the fourth moving shaft 321 are fixedly connected to the driving rod 311, respectively. A groove is provided on the limiting semi-ring 314. Friction blocks 319 are slidably installed inside. When the two movable frames 301 approach each other, the two friction blocks 319 will first adhere to the cable 101 under the elastic force of the third spring 317. During the process of the two limiting semi-rings 314 approaching each other until they are pressed together, the friction blocks 319 always adhere to the outer surface of the cable 101. A second movable shaft 313 is fixedly installed on the side of the friction block 319 away from the cable 101. The second movable shaft 313 is fixedly connected to the driving rod 311. A retaining ring 320 is fixedly installed on the outer surface of the second movable shaft 313. A third spring 317 is wound around the outer surface of the second movable shaft 313. One end of the third spring 317 is fixedly installed on the side of the retaining ring 320, and the other end of the third spring 317 is fixedly installed on the limiting semi-ring 314.

[0034] When the machine starts working, the two movable frames 301 approach each other under the action of the first spring 303. When the movable frames 301 approach each other, the first top shaft 308 moves towards the cable 101 under the action of the second spring 310. The first top shaft 308 lifts the cable 101 and drives the mounting frame 201 to rise and fall along the inner wall of the protective shell 202 by rotating the screw rod 501. This keeps the cable 101 between the mounting frames 201 on the two adjacent automatic tensioning grounding shield clamps in a taut state, thus preventing the slack cable 101 from swaying in the wind. When the two movable frames 301 approach each other, the two friction blocks 319 first press against the cable 101 under the action of the elastic force of the third spring 317. When the two limiting half rings 314 approach each other until they are pressed together, the friction blocks 319 always press against the outer surface of the cable 101. The limiting half rings 314 and the friction blocks 319 fix the cable 101, making the cable unable to move.

[0035] As mentioned in the background section, this application proposes an automatic tensioning grounding shield clamp.

[0036] Appendix Figure 4 To the attached Figure 8As shown, in a preferred embodiment, the cleaning assembly includes a mounting plate 401 fixedly mounted on the protective housing. The mounting plate 401 is located below the mounting frame 201. A transmission shaft 404 is rotatably mounted on the mounting plate 401. The transmission shaft 404 is located inside the protective housing 202. A rotating shaft 402 is rotatably mounted on the mounting plate 401. A rotating fan blade 403 is fixedly mounted on the outer surface of the rotating shaft 402. A rotating disk 407 is fixedly mounted on the lower outer surface of the transmission shaft 404. A cleaning assembly and a striking assembly are mounted on the rotating disk 407. The cleaning assembly is connected to the rotating shaft 402 and the striking assembly, respectively. A transmission belt 405 is connected to the transmission shaft 404. The transmission shaft 404 is connected to the rotating shaft 402 through the transmission belt 405 to form a belt drive. A brush 408 is fixedly mounted on the end of the rotating disk 407 away from the transmission shaft 404.

[0037] As mentioned in the background section, this application proposes an automatic tensioning grounding shield clamp.

[0038] Appendix Figure 5 To the attached Figure 8 As shown, in a preferred embodiment, the striking assembly includes a plurality of impact shafts 409 circumferentially slidably mounted on a rotating disk 407. Both ends of the impact shafts 409 are hemispherical. A limit ring 411 is fixedly mounted on the outer surface of the impact shafts 409. A fourth spring 410 is wound around the outer surface of the impact shafts 409. One end of the fourth spring 410 is fixedly mounted on the upper side of the rotating disk 407, and the other end of the fourth spring 410 is fixedly mounted on the limit ring 411. A lifting block 406 is rotatably mounted on the outer surface of the transmission shaft 404. An installation block 412 is fixedly mounted on the side of the lifting block 406. The installation block 412 is fixedly mounted inside the protective shell 202. The hemispherical outer surface of the upper end of the impact shaft 409 abuts against the lower end face of the lifting block 406. The lower end face of the lifting block 406 is a closed curved surface with a smooth lifting motion.

[0039] Under the influence of wind in the environment, the rotating fan blades 403 drive the rotating shaft 402 to rotate. The rotating shaft 402 drives the transmission shaft 404 to rotate via the transmission belt 405. The transmission shaft 404 drives the brush 408 to move via the rotating disk 407. When the brush 408 moves, the impact shaft 409 moves along the lower end face of the lifting block 406. At this time, under the action of the lower end face of the lifting block 406, the impact shaft 409 moves up and down. The impact shaft 409 knocks the iced parts near the mounting frame 201, and the brush 408 cleans up the ice. At the same time, the brush 408 can also clean up rainwater and debris near the mounting frame, preventing the cleaned ice and rainwater debris from accumulating near the mounting frame 201. It also prevents the long-term accumulation of debris and water from causing corrosion and repeated icing of the mounting frame, thereby improving the operational stability of the line equipment.

[0040] The working principle of this invention is as follows: (i) When the work begins, the two moving frames 301 approach each other under the action of the first spring 303. When the moving frames 301 approach each other, the first top shaft 308 moves towards the cable 101 under the action of the second spring 310. The cable 101 is lifted by the first top shaft 308, and the mounting frame 201 is driven to rise and fall along the inner wall of the protective shell 202 by rotating the screw rod 501. This keeps the cable 101 between the mounting frames 201 on the two adjacent automatic tensioning grounding shielding clamps in a taut state, thus preventing the slack cable 101 from swaying in the wind. When the two moving frames 301 approach each other, the two friction blocks 319 first stick to the cable 101 under the action of the elastic force of the third spring 317. When the two limiting half rings 314 approach each other until they stick together, the friction blocks 319 always stick to the outer surface of the cable 101. The cable 101 is fixed by the limiting half rings 314 and the friction blocks 319, so that the cable cannot move.

[0041] (ii) Under the action of wind in the environment, the rotating fan blade 403 drives the rotating shaft 402 to rotate. The rotating shaft 402 drives the transmission shaft 404 to rotate through the transmission belt 405. The transmission shaft 404 drives the brush 408 to move through the rotating disk 407. When the brush 408 moves, the impact shaft 409 moves along the lower end face of the lifting block 406. At this time, under the action of the lower end face of the lifting block 406, the impact shaft 409 moves up and down. The impact shaft 409 knocks on the ice near the mounting frame 201 and the brush 408 cleans up the ice. At the same time, the brush 408 can also clean up rainwater and debris near the mounting frame, preventing the cleaned ice and rainwater debris from accumulating near the mounting frame 201. It also prevents the long-term accumulation of debris and water from causing corrosion and repeated icing of the mounting frame, thereby improving the operational stability of the line equipment.
