Description

Technical Field

[0001] This utility model relates to the field of wiring devices, and in particular to a wiring device for photovoltaic cable conduits. Background Technology

[0002] Photovoltaic cables are wires and cables specifically designed and used in solar photovoltaic power plants. These cables are primarily used for power transmission and connection of photovoltaic modules in solar power systems, as well as for connections with other electrical equipment. To protect the cables, improve safety, and facilitate maintenance and management, photovoltaic cables are typically installed using conduits.

[0003] The Chinese patent with publication number CN222814152U, which has been authorized, prevents wear between the end of the main body of the photovoltaic cable and the inner wall of the main body of the conduit by setting up an auxiliary mechanism. However, in actual use, when the photovoltaic cable runs through the conduit, in addition to the end of the photovoltaic cable, the outer surface of the photovoltaic cable will also come into contact with the inner wall of the conduit. When the conduit is long, the friction between the photovoltaic cable and the conduit is large. The sand and gravel material remaining inside the conduit can easily cut the outer surface of the photovoltaic cable, which is not conducive to the subsequent use of the photovoltaic cable. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art, and to propose a photovoltaic cable conduit threading device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic cable conduit threading device, comprising a conduit, a clamp provided on the outer surface of one end of the conduit, a coating component provided on one end of the clamp, a protective shell provided on one end of the coating component, a pull rope embedded in one end of the conduit, a cleaning component provided on one end of the pull rope, a photovoltaic cable provided on the other end of the cleaning component, and the photovoltaic cable passing through the clamp, the coating component and the protective shell, and a driving component embedded between the coating component and the protective shell.

[0006] Preferably, the cleaning component includes a fixed sleeve fixedly disposed at one end of the photovoltaic cable and a fixed housing fixedly connected to one end of the fixed sleeve. A first motor is fixedly connected inside the fixed housing, and a rotating disk is rotatably connected to the inner wall of the fixed housing. One end of the rotating disk is fixedly connected to a pull rope. Three sets of support rods are fixedly connected at intervals on the outer surface of the fixed housing. Each of the three sets of support rods is provided with a ball bearing at its end, and the ball bearing is in contact with the inner wall of the cable conduit.

[0007] Preferably, the output end of the first motor is fixedly connected to two connecting rods, and a rotating sleeve is rotatably connected to the outer surface of the fixed housing. One end of each of the two sets of connecting rods passes through the rotating disk and is fixedly connected to the inner wall of the rotating sleeve. A threaded sleeve is fixed to the outer surface of the rotating sleeve by bolts, and an annular brush is fixedly connected to the outer surface of the threaded sleeve, with the annular brush in contact with the inner wall of the conduit.

[0008] Preferably, the coating assembly includes a mounting housing fixedly connected to one end of the clamp, a first fixing plate and a second fixing plate fixedly connected to the inner wall of the mounting housing, the first fixing plate, the second fixing plate and the mounting housing forming a cavity, a feed pipe fixedly connected to the outer surface of the mounting housing and communicating with the cavity, a sealing end cap provided on the feed pipe, and two sets of the first fixing plate, the second fixing plate and the feed pipe are symmetrically arranged.

[0009] Preferably, a transmission ring is rotatably connected to the inner side of the mounting housing, and two receiving grooves are formed on the outer surface of the transmission ring. Two sponge blocks are fixedly connected to the inner side of the transmission ring, and the positions of the receiving grooves, sponge blocks and cavities correspond one-to-one. Both sets of sponge blocks are in contact with the outer surface of the photovoltaic cable. Micropores are formed on the inner wall of the mounting housing and the inner wall of the receiving grooves.

[0010] Preferably, the drive assembly includes a second motor fixedly connected inside the mounting housing and a gear rotatably connected to one end of the mounting housing, wherein the output end of the second motor is fixedly connected to the gear, and an external gear ring is fixedly connected to one end of the transmission ring, and the external gear ring meshes with the gear.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] This application achieves cleaning of the inner wall of the conduit by setting up a cleaning component, which can prevent the photovoltaic cable from being scratched by sand particles after entering the conduit. The threaded sleeve and the annular brush are detachable, which facilitates the replacement of the annular brush after it wears out. With the support of the support rod, the annular brush can make complete contact with the inner wall of the conduit, ensuring the cleaning effect of the annular brush.

[0013] In this application, by setting up coating components and driving components, two sets of sponge blocks are spirally coated on the outer surface of the photovoltaic cable, which further reduces the damage to the photovoltaic cable during the wiring process. This not only saves costs but also avoids the problem of excessive lubricant accumulating inside the cable tube. By intermittently flowing the lubricant and setting up micropores, the flow rate of the lubricant is limited, thus preventing excessive lubricant from appearing on the sponge blocks.

Detailed Implementation

[0021] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention. Example

[0022] Reference Figures 1 to 6 A photovoltaic cable conduit threading device includes a conduit 1, a clamp 2 on the outer surface of one end of the conduit 1, a coating component 3 on one end of the clamp 2, a protective shell 4 on one end of the coating component 3, a pull rope 6 embedded in one end of the conduit 1, a cleaning component 8 on one end of the pull rope 6, and a photovoltaic cable 5 on the other end of the cleaning component 8. The photovoltaic cable 5 passes through the clamp 2, the coating component 3, and the protective shell 4. A driving component 7 is embedded between the coating component 3 and the protective shell 4. The clamp 2 can fix the coating component 3 to one end of the conduit 1. The driving component 7 is used to drive the coating component 3 to spirally coat the photovoltaic cable 5 with lubricant. The cleaning component 8 is used to connect the photovoltaic cable 5 and the pull rope 6, and can also clean the sand and gravel on the inner wall of the conduit 1.

[0023] The cleaning component 8 includes a fixed sleeve 81 fixedly mounted on one end of the photovoltaic cable 5 and a fixed housing 82 fixedly connected to one end of the fixed sleeve 81. A first motor 83 is fixedly connected inside the fixed housing 82. A rotating disk 86 is rotatably connected to the inner wall of the fixed housing 82. One end of the rotating disk 86 is fixedly connected to the pull rope 6. Three sets of support rods 84 are fixedly connected at intervals on the outer surface of the fixed housing 82. Each of the three sets of support rods 84 is provided with a ball bearing at its end, and the ball bearing is in contact with the inner wall of the conduit 1. The ball bearing is used to reduce the friction between the support rods 84 and the conduit 1. By pulling the pull rope 6, the rotating disk 86, the fixed housing 82, the fixed sleeve 81 and the photovoltaic cable 5 can all be moved, thereby realizing the threading operation of the photovoltaic cable 5. With the support of the three sets of support rods 84, the position of the fixed housing 82 can be kept at the center of the conduit 1 to avoid friction damage to the end of the photovoltaic cable 5.

[0024] Two connecting rods 85 are fixedly connected to the output end of the first motor 83. A rotating sleeve 87 is rotatably connected to the outer surface of the fixed housing 82. One end of each of the two connecting rods 85 passes through the rotating disk 86 and is fixedly connected to the inner wall of the rotating sleeve 87. A threaded sleeve 88 is fixed to the outer surface of the rotating sleeve 87 by bolts. An annular brush 89 is fixedly connected to the outer surface of the threaded sleeve 88, and the annular brush 89 is in contact with the inner wall of the conduit 1. The first motor 83 and the two connecting rods 85 can drive the rotating sleeve 87 to rotate, thereby causing the threaded sleeve 88 and the annular brush 89 to rotate. This causes the annular brush 89 to rotate back and forth, scraping off the sand particles on the inner wall of the conduit 1 and pushing the sand particles to move together with the annular brush 89, thus cleaning the inner wall of the conduit 1. When the annular brush 89 rotates back and forth with a small amplitude, it can ensure the cleaning effect of the annular brush 89 without affecting the pulling effect of the pull rope 6.

[0025] The coating assembly 3 includes a mounting housing 31 fixedly connected to one end of the clamp 2. A first fixing plate 32 and a second fixing plate 33 are fixedly connected to the inner wall of the mounting housing 31. The first fixing plate 32, the second fixing plate 33 and the mounting housing 31 form a cavity 38. A feed pipe 34 is embedded and fixedly connected to the outer surface of the mounting housing 31 and communicates with the cavity 38. A sealing end cap is provided on the feed pipe 34. Two sets of the first fixing plate 32, the second fixing plate 33 and the feed pipe 34 are symmetrically arranged. Lubricating fluid can be input into the cavity 38 for storage through the feed pipe 34.

[0026] A transmission ring 35 is rotatably connected to the inner side of the mounting housing 31. Two receiving grooves 36 are formed on the outer surface of the transmission ring 35. Two sponge blocks 37 are fixedly connected to the inner side of the transmission ring 35. The positions of the receiving grooves 36, sponge blocks 37 and cavities 38 correspond one-to-one. Both sets of sponge blocks 37 are in contact with the outer surface of the photovoltaic cable 5. Micropores are formed on the inner wall of the mounting housing 31 and the inner wall of the receiving grooves 36. When the receiving grooves 36 and cavities 38 are aligned, the lubricant inside the cavity 38 can enter the receiving grooves 36 through the micropores, enabling intermittent flow. The lubricant inside the receiving grooves 36 can enter the sponge blocks 37, and the lubricant can be applied to the outer surface of the photovoltaic cable 5 through the sponge blocks 37.

[0027] The drive assembly 7 includes a second motor 73 fixedly connected inside the mounting housing 31 and a gear 71 rotatably connected to one end of the mounting housing 31. The output end of the second motor 73 is fixedly connected to the gear 71. One end of the transmission ring 35 is fixedly connected to an external gear ring 72, which meshes with the gear 71. By driving the gear 71 to rotate through the second motor 73, the external gear ring 72 can drive the transmission ring 35 to rotate, thereby enabling the two sets of sponge blocks 37 to rotate around the photovoltaic cable 5.

[0028] In use, this invention uses an external limiting device to position the photovoltaic cable 5 at the center of the protective housing 4. An external winding device pulls the rope 6, causing the photovoltaic cable 5 to continuously enter the conduit 1 until it penetrates the conduit, thus enabling the cable threading operation. During threading, the first motor 83 causes the annular brush 89 to rotate slightly back and forth, sweeping away sand and other debris from the inner wall of the conduit 1. The annular brush 89 pushes the sand and other debris out of the conduit 1, preventing the photovoltaic cable 5 from being scratched by sand after entering the conduit 1. The threaded sleeve 88 and the annular brush 89 are detachable, facilitating replacement of the worn brush 89. Supported by the support rod 84, the annular brush 89 maintains complete contact with the inner wall of the conduit 1, ensuring thorough cleaning. For a cleaning effect, when the photovoltaic cable 5 is threaded in, the second motor 73 drives the transmission ring 35 to rotate, causing the two sets of sponge blocks 37 to apply lubricant in a spiral motion on the outer surface of the photovoltaic cable 5. Applying lubricant reduces friction during the threading process of the photovoltaic cable 5, further reducing damage to the photovoltaic cable 5 during threading. The spiral application reduces the amount of lubricant used while ensuring that the photovoltaic cable 5 is lubricated all around, saving costs and preventing excessive lubricant accumulation inside the conduit 1. When the transmission ring 35 rotates, the lubricant inside the cavity 38 can intermittently enter the receiving groove 36, allowing the lubricant on the sponge blocks 37 to be replenished in a timely manner. The intermittent flow of lubricant and the setting of micropores limit the flow rate of lubricant, preventing excessive lubricant on the sponge blocks 37.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
