Automatic wiring device for photovoltaic cables

Abstract

This utility model relates to the field of cable installation technology, specifically to an automatic photovoltaic cable wiring device, comprising a semi-circular disc, auxiliary components, connecting columns, sliding discs, nuts, and balls. In this utility model, one end of the cable is first placed between two sets of sliding discs, and then the nuts are rotated. At this time, the two sets of nuts move towards each other, thereby clamping one end of the cable. After the cable is fixed, the semi-circular disc is placed inside the pipe. The balls contact the inner wall of the pipe, reducing the friction between the semi-circular disc and the pipe. Finally, due to its own weight, the semi-circular disc slides inside the pipe to the inverter or combiner box installation location, effectively improving cable routing efficiency. Furthermore, the slide rail is installed inside the mounting cylinder, allowing the balls to rotate freely, thus assisting the balls in sliding on the inner wall of the pipe. When the distance between the two sets of semi-circular discs changes, it drives the sleeve and the sliding shaft inside the sleeve to move, making the overall device more stable.

Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to an automatic wiring device for photovoltaic cables. Background Technology

[0002] The automatic photovoltaic cable laying device reduces manual operation through automation technology, improves construction efficiency and safety, and optimizes cable laying quality. The device uses a motor to drive rollers and a rotating shaft to automatically lay cables, replacing the traditional manual pulling method, which significantly reduces physical exertion and operation time.

[0003] While traditional photovoltaic cable automatic wiring devices can automatically lay cables, the location and scenario of cable placement vary. When cables need to be introduced from the array on the roof into the building (to connect to the inverter or combiner box), conduits (usually metal flexible tubing or PVC conduit) must be used at the penetration holes. However, when cables are laid in conduits, they may get stuck inside the conduits, requiring constant adjustments by staff, which affects work efficiency. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an automatic photovoltaic cable wiring device that can quickly pass through pipes and improve work efficiency.

[0005] To address the problems in the existing technology, this utility model provides an automatic photovoltaic cable wiring device, including a semi-circular disk, an auxiliary component mounted on the semi-circular disk, a connecting post slidably mounted inside the semi-circular disk, two sets of sliding disks slidably mounted on the connecting post, a rubber block installed inside the sliding disk, a nut threadedly connected to the inside of the sliding disk, and a ball installed inside the mounting cylinder, capable of clamping one end of the cable and driving the cable quickly through the pipe to the inverter or combiner box installation location.

[0006] Specifically, the auxiliary component includes a rotating gear, a bidirectional threaded rod, a connecting column, a sliding disc, and a nut. A set of semi-circular discs are threaded to both ends of the bidirectional threaded rod. A set of rotating gears is fixedly installed on the bidirectional threaded rod, which can drive the two sets of semi-circular discs to slide, thereby changing their position to adapt to pipes of different sizes.

[0007] Specifically, a set of slide rails is provided on the outer wall of the semicircular disk, and multiple sets of mounting cylinders are installed inside the slide rails. Multiple sets of mounting blocks are fixedly installed on the upper end of the semicircular disk, and a set of sleeves is installed between two sets of mounting blocks. A set of fixing columns is fixedly installed on the semicircular disk, and a cable is installed between the two sets of semicircular disks. One end of the cable is clamped between the two sets of sliding disks. The semicircular disk is slidably connected to the inside of the pipe, fixing the two sets of semicircular disks together, thereby increasing the overall stability.

[0008] Beneficial effects: 1. In this utility model, after the two sets of sliding discs hold the cable, the semi-circular disc is placed into the pipe and then slides down the inner wall of the pipe to the lower end of the pipe, thereby improving the cable placement efficiency.

[0009] 2. In this utility model, after the rotating gear is rotated, the bidirectional threaded rod will also move accordingly, thereby pushing the semi-circular disk to slide on the connecting column, thus adapting to pipes of different specifications and sizes. Attached Figure Description

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0015] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0016] In the description of this application, spatial relation terms such as "below," "under," "below," "below," "above," "over," etc., are used herein to describe the relationship between one element or feature shown in the figures and other elements or features. It should be understood that, in addition to the orientation shown in the figures, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figures is flipped, an element or feature described as "below" or "under" or "below" of other elements or features will be oriented "above" other elements or features. Therefore, the exemplary terms "below" and "under" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein are interpreted accordingly.

Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0018] Example 1: like Figures 3-4The photovoltaic cable automatic wiring device shown includes a semi-circular disk 1, an auxiliary component 2 mounted on the semi-circular disk 1, a connecting post 212 slidably mounted inside the semi-circular disk 1, two sets of sliding disks 213 slidably mounted on the connecting post 212, rubber blocks installed inside the sliding disks 213, a nut 214 threadedly connected to the inside of the sliding disks 213, and a ball 114 installed inside the mounting cylinder 113, capable of clamping one end of the cable 111 and driving the cable 111 quickly through the pipe 110 to the inverter or combiner box installation location.

[0019] like Figures 1-2 As shown, a set of slide rails 112 are provided on the outer wall of the semi-circular disk 1. Multiple sets of mounting cylinders 113 are installed inside the slide rails 112. Multiple sets of mounting blocks 115 are fixedly installed on the upper end of the semi-circular disk 1. A set of sleeves 116 is installed between two sets of mounting blocks 115. A set of fixing posts 117 are fixedly installed on the semi-circular disk 1. A cable 111 is installed between the two sets of semi-circular disks 1. One end of the cable 111 is clamped between the two sets of sliding disks 213. The semi-circular disk 1 is slidably connected to the inside of the pipe 110, which fixes the two sets of semi-circular disks 1 together, thereby increasing the overall stability.

[0020] like Figures 3-4 As shown, first, place one end of cable 111 between two sets of sliding discs 213, then rotate nut 214. At this time, the two sets of nuts 214 will move towards each other, thereby clamping one end of cable 111. After the cable 111 is fixed, place the entire semi-circular disc 1 inside the pipe 110. The ball 114 will contact the inner wall of the pipe 110, reducing the friction between the semi-circular disc 1 and the pipe 110. Finally, due to the weight of the semi-circular disc 1 itself, it slides inside the pipe 110 and slides to the inverter or combiner box installation location, which can effectively improve the cable 111 layout efficiency.

[0021] like Figures 1-2 As shown, the slide rail 112 is installed inside the mounting cylinder 113. The mounting cylinder 113 allows the ball 114 to rotate freely, thereby assisting the ball 114 to slide on the inner wall of the pipe 110. When the distance between the two sets of semi-circular discs 1 changes, it will drive the sleeve 116 and the sliding shaft inside the sleeve 116 to move, thereby making the overall equipment more stable.

[0022] Example 2: like Figure 3 and Figure 4As shown, the auxiliary component 2 includes a rotating gear 210, a bidirectional threaded rod 211, a connecting column 212, a sliding disc 213, and a nut 214. Both ends of the bidirectional threaded rod 211 are threadedly connected to a set of semi-circular discs 1. A set of rotating gears 210 is fixedly installed on the bidirectional threaded rod 211, which can drive the two sets of semi-circular discs 1 to slide, thereby changing their positions to adapt to pipes 110 of different sizes.

[0023] The above-described Embodiment 2 is a further improvement upon Embodiment 1; like Figure 3 and Figure 4 As shown, when it is necessary to adjust the distance between the two sets of semi-discs 1, simply rotate the rotating gear 210. At this time, the rotating gear 210 will drive the bidirectional threaded rod 211 to rotate. Under the limit of the mounting block 115 and the sleeve 116, the semi-disc 1 slides on the connecting column 212, thereby changing the distance between the two sets of semi-discs 1 to adapt to pipes 110 of different sizes.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
