Description

Technical Field

[0001] The present invention relates to the technical field of cable protection devices, and particularly to a cable protection device for wind power generation. Background Art

[0002] With the rapid development of the wind power industry, the scale of wind farms is constantly expanding. The underground cables of the collector lines in wind farms, as an important part of wind farms, play an important role in transmitting electric energy. When a wind turbine is operating, there are various types of cables used. At the same time, the cables in the wind turbine tower will hang down by more than ten meters or dozens of meters according to the height of the tower. As the operation time of the equipment increases, the cables may age. Especially in wind farms located in high-altitude areas, due to the large temperature difference between day and night and the harsh equipment operation environment, the cable aging phenomenon may be more serious. The aged cables are prone to poor sealing, resulting in the cable heads getting waterlogged in rainy and snowy weather, and then causing insulation breakdown.

[0003] The aging of the cable outer skin refers to the phenomenon that during the use of the cable, due to the influence of environmental factors, the outer skin material undergoes physical, chemical or mechanical changes and loses its original performance. The aging of the cable outer skin may cause its physical structure to become fragile, especially in the case of cracks and blisters. This change in the physical structure may cause the original fixing devices (such as cable racks, cable trays, etc.) that closely fit the cable to lose their original fixing effect. Summary of the Invention

[0031] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification

[0032] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below

[0033] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments individually or selectively

[0034] Furthermore, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included

[0035] Example 1. Refer to Figures 1-6, which is the first embodiment of the present invention, provides a cable protection device for wind power generation. This device includes an installation unit 100, a sliding unit 200, and a clamping unit 300. The clamping unit 300 and the sliding unit 200 cooperate to clamp the cable 102 included in the installation unit 100. The sliding unit 200 limits the clamping of the cable 102, and the clamping unit 300 is used to clamp and limit the cable 102, so that the cable 102 can be stably installed. When the cable 102 ages, neither the clamping unit 300 nor the sliding unit 200 can clamp the cable 102, and the cable 102 loses its limit and sags under the action of gravity, resulting in an unstable connection of the cable 102. At this time, the sliding unit 200 slides down, and the falling of the sliding unit 200 in the vertical direction enables the clamping unit 300 to further clamp the aged cable 102, avoiding the continuous downward dragging of the cable 102 under the action of gravity and making the installation of the cable 102 more stable.

[0036] Among them, the installation unit 100 includes an installation component 101, a cable 102 disposed in the installation component 101, and an installation ring 103 disposed in the installation component 101. The stable installation of the sliding unit 200 and the clamping unit 300 can be achieved through the installation ring 103 and the installation component 101.

[0037] The sliding unit 200 includes a first clamping component 201 for clamping the cable 102, a sliding component 202 slidably disposed on the installation component 101, a connection component 203 movably disposed on the first clamping component 201, and a pushing component 204 disposed on the first clamping component 201. And the first clamping component 201 includes a first clamping half-ring 201a, a second clamping half-ring 201b movably disposed on the first clamping half-ring 201a, and a torsion spring 201c pressed on the first clamping half-ring 201a and pressing against the second clamping half-ring 201b. Anti-slip rubber is provided on the inner circumferential surfaces of the first clamping half-ring 201a and the second clamping half-ring 201b. The fixing of the cable 102 is achieved through the limitation of the clamping unit 300. At this time, the first clamping component 201 clamps the cable 102, and the first clamping component 201 can also be stably installed on the installation component 101. Multiple groups of the sliding unit 200 and the clamping unit 300 are arranged side by side up and down in the installation component 101, which can stably clamp and limit the long cable 102.

[0038] The clamping unit 300 includes a second clamping assembly 301 disposed on the mounting ring 103, a pressing assembly 302 disposed on the second clamping assembly 301, a fixing block 303 disposed on the second clamping assembly 301 and connected to the mounting assembly 101, a limiting assembly 304 disposed on the second clamping assembly 301, and a disengaging assembly 305 disposed on the limiting assembly 304. The clamping unit 300 is located directly below the sliding unit 200. The clamping unit 300 and the sliding unit 200 correspond one-to-one with the number of cables 102, isolating the multiple cables 102 from each other to avoid frictional damage. The multiple clamping units 300 are circumferentially distributed around the central axis of the mounting ring 103. The second clamping assembly 301 has the same structure as the first clamping assembly 201, but the torsion springs 201c used in the second clamping assembly 301 and the first clamping assembly 201 can provide different clamping forces. The limiting assembly 304 limits the clamping magnitude of the second clamping assembly 301 to prevent the second clamping assembly 301 from applying excessive pressure and damaging the cable 102. By providing the disengaging assembly 305, it is possible to facilitate the separation of the limiting assembly 304 from the second clamping assembly 301 under the action of the pushing assembly 204.

[0039] During use, the operator toggles the connecting assembly 203 to move the sliding unit 200 away from the clamping unit 300. At the same time, the operator pulls the connecting assembly 203 to clamp the cable 102 with the first clamping assembly 201 and the second clamping assembly 301. By adjusting the limiting assembly 304, the second clamping assembly 301 just clamps the cable 102 without causing damage to the cable 102. The second clamping assembly 301 fixes and limits the cable 102. At this time, the first clamping assembly 201 clamps the cable 102 only to stably mount the sliding unit 200 on the mounting assembly 101. When the cable 102 ages and the protective rubber on the cable 102 becomes loose, the clamping of the cable 102 by the first clamping assembly 201 and the second clamping assembly 301 both becomes loose. The cable 102 loses the limit of the second clamping assembly 301 and drops, and the first clamping assembly 201 also drops without the limit of the cable 102. The pushing assembly 204 acts on the limiting assembly 304 to release the limit of the second clamping assembly 301 by the limiting assembly 304, and the second clamping assembly 301 further clamps to clamp the aging cable 102, preventing the aging cable 102 from being pulled under the action of gravity and the connection from being unstable. An alarm is given through the pressing assembly 302 to remind the operator to perform maintenance.

[0040] Example 2, refer to Figures 1-7, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that after the cable 102 ages, the clamping assembly one 201 no longer clamps the cable 102. The clamping assembly one 201 drops under the action of gravity. At this time, the pressing plate 204c acts on the limiting assembly 304, causing the limiting assembly 304 to swing and releasing the limiting effect on the clamping assembly two 301, so that the clamping assembly two 301 can further clamp and limit the cable 102.

[0041] Compared with Embodiment 1, further, the mounting assembly 101 includes a mounting sleeve 101a and a mounting plate 101b provided on the inner wall of the mounting sleeve 101a. The fixing block 303 is fixedly installed on the mounting plate 101b and can stably limit the clamping unit 300.

[0042] Preferably, the sliding assembly 202 includes a sliding plate 202a provided on the clamping assembly one 201 and a slider 202c provided on the sliding plate 202a. The clamping assembly one 201 is slidably arranged on the mounting plate 101b through the setting of the slider 202c.

[0043] Wherein, a sliding groove 101c for cooperating with the slider 202c to slide is provided on the mounting plate 101b.

[0044] Further, the connecting assembly 203 includes a connecting rod one 203a movably arranged on the clamping assembly one 201, a connecting rod two 203b movably arranged on the clamping assembly two 301 and movably connected to the connecting rod one 203a. One end of the connecting rod one 203a is movably connected to the outer peripheral surface of the clamping half-ring one 201a, and the other end of the connecting rod one 203a is movably connected to the connecting rod two 203b.

[0045] Furthermore, the pushing assembly 204 includes a mounting block one 204a provided on the clamping assembly one 201, a connecting block 204b provided on the mounting block one 204a, and a pressing plate 204c provided on the bottom surface of the connecting block 204b. The pressing plate 204c drops downward under the action of gravity, and the pressing plate 204c acts on the limiting assembly 304, causing the limiting assembly 304 to swing and releasing the limiting effect on the clamping assembly two 301.

[0046] The remaining structures are the same as those in Embodiment 1.

[0047] Embodiment 3, refer to Figures 1-9, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that by adjusting the sliding distance of the limit plate 304f, the clamping force of the second clamping assembly 301 can be controlled to avoid over-clamping the cable 102 and causing damage to the cable 102; when the pressing plate 204c is pressed against the limit assembly 304 under the action of gravity, the ball 305d rolls, reducing the resistance of the limit assembly 304 to swing and enabling the rotation of the rotating block 304a.

[0048] Compared with Embodiment 2, further, the pressing assembly 302 includes a sealing plate 302a provided on the second clamping assembly 301 and an alarm 302b provided on the second clamping assembly 301. There is a groove on the second clamping assembly 301 for installing the alarm 302b; the sealing plate 302a is fitted and extends into the groove.

[0049] Preferably, the limit assembly 304 includes a rotating block 304a, a fixed shaft 304b provided on the second clamping assembly 301 and movably connected to the rotating block 304a, an extension block 304c provided on the rotating block 304a, a limit block 304d provided on the rotating block 304a, a threaded rod 304e threaded on the limit block 304d, a limit plate 304f slidably provided on the rotating block 304a, and a pressing plate 304g provided on the limit plate 304f. By adjusting the sliding distance of the limit plate 304f, the clamping force of the second clamping assembly 301 can be controlled to avoid over-clamping the cable 102 and causing damage to the cable 102.

[0050] Further, a baffle 304h is provided on the limit block 304d. The baffle 304h is pressed against the upper end surface of the second clamping assembly 301 for limiting to avoid blocking the clamping of the second clamping assembly 301.

[0051] Furthermore, the detachment assembly 305 includes a moving plate 305a slidably provided in the pressing plate 304g, a spring 305b provided on the moving plate 305a and connected to the inner side of the pressing plate 304g, a second mounting block 305c provided on the moving plate 305a, and a ball 305d movably provided on the second mounting block 305c. The ball 305d is in rolling contact with the second clamping assembly 301. When the pressing plate 204c is pressed against the limit assembly 304 under the action of gravity, the ball 305d rolls, reducing the resistance of the limit assembly 304 to swing and enabling the rotation of the rotating block 304a. By providing multiple sets of detachment assemblies 305, the pressing of the second clamping assembly 301 on the limit assembly 304 is more fitting and stable.

[0052] In particular, an installation chamber 304i for installing the moving plate 305a is provided in the pressing plate 304g.

[0053] The remaining structure is the same as that of Embodiment 2.
