Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cable laying, and more specifically, to a photovoltaic cable laying bridge and a use method thereof. Background Art
[0002] Cable tray is a commonly used tool for laying cables, mainly used to lay cables together. The cable tray generally includes a tray body and a cover plate to form a channel similar to a pipe, and the cover plate is mainly used to cover the accommodating cavity of the tray body. The structure of the cover plate and the tray body is conducive to the laying of cables.
[0003] At present, photovoltaic power generation is often constructed on rooftops, and its cables need to be laid vertically over low walls. However, the thickness of the low walls is small, and the bending angle of the cables should not be too large. This leads to the need to frequently customize bridges that can climb over low walls for laying cables, which affects construction efficiency. The bridge structure is fixed and needs to be pre-installed on the wall, which increases the difficulty of laying cables and makes the installation more inconvenient.
[0004] In order to solve the above problems, the present application proposes a photovoltaic cable laying bridge and a method of using the same. Summary of the invention
[0005] The object of the present invention is to provide a photovoltaic cable laying bridge and a use method thereof, so as to solve the problem of inconvenience in cable laying in low wall areas.
[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: A photovoltaic cable laying bridge, comprising a long bridge and a long cover plate on its outer side, which is longitudinally installed on a low wall surface of a roof; The movable bridge is located at the top of the low wall. Adjacent movable bridges are hinged through the transition parts at both ends to form a multi-stage turning structure to assist the 360° turning laying of the cable. The interior of the movable bridge is provided with a rubber pad to receive the cable to prevent scratches. Side plates are provided on both sides of the ends of the movable bridge to connect with adjacent movable bridges. The short bridge is slidably connected to the upper end of the long bridge, and is used to drive the movable bridge to be lowered to the outside of the low wall, so that the cable only forms a regional bend at the end of the laying process to prevent scratches. Both ends of the movable bridge are provided with 120° special-shaped bridges, which are connected to the extension frame installed at the upper end of the short bridge through the inner convex frame; The movable cover plate is located on the outside of the movable bridge and is a two-section structure used to close the movable bridge. A conical block is provided on the outside of the transition part at one end of the movable bridge, and a positioning groove is provided on the outside of the transition part at the other end. The clamping connection between the conical block and the positioning groove is used to pre-fix the adjacent movable bridge to 120°. The movable cover plate is also used to be sleeved and fixed after the adjacent movable bridge is pre-fixed.
[0007] On the other hand, the present invention also provides a method for using a photovoltaic cable laying bridge, the specific method is as follows: S1: In the preparation stage, the short bridge is placed on the outer side of the upper end of the long bridge, and the adjacent movable bridge is unfolded to form a vertical state; S2: In the pre-construction stage, the long bridge is installed on the outside of the low wall, and space for the movable bridge is reserved above; S3: During the pre-laying process, the special-shaped bridge at the lower end of the movable bridge is connected and fixed with the short bridge, and the unfolded movable bridge is vertically hung on the outside of the low wall. At this time, the upper end of the special-shaped bridge protrudes outward to form a 120° inclination angle; S4: During the laying control phase, the cable is lowered longitudinally, during which it only contacts the protruding part of the upper end of the special-shaped bridge and is protected by the rubber pad inside; S5: In the post-laying processing stage, the movable bridge is pulled up and turned over to form a multi-stage turning structure above the low wall, and finally a 360° turning angle is formed. At this time, the conical block is clamped in the positioning groove to pre-fix the adjacent movable bridge; S6: During the fixing construction phase, two movable cover plates are sleeved on the outside of the movable bridge and merged, and then the adjacent movable cover plates are fixed by a slide plate, thereby limiting every two adjacent movable bridges to a 120° rotation angle; S7: When the movable cover plate is installed, the guide plate drives the folding plate to fold outward, and then under the effect of the rebound force and the squeezing of the elastic protrusion, the blocking pad fills the gap between the folding plate and the movable bridge frame to form a seal, and then the low wall is connected through the pillar; S8: In the final processing stage, the cables are dragged to adjust the spacing so that they are laid neatly, and finally the long cover plates and short cover plates are installed outside the long bridge and short bridge respectively.
[0008] Beneficial effects of the present invention: The present invention connects adjacent movable bridges through an adapter, and combines rubber pads and side panels to form protection for the side surfaces, so that multiple movable bridges can form a multi-stage inclined structure in the low wall area of the roof, and finally form a 360° turn, which is convenient for laying cables and reduces the difficulty of laying. At the same time, it effectively avoids damage caused by excessive bending of the cables, keeps them in a stable laying state, and improves the quality and life of the cables. The present invention uses a sliding connection between a short bridge and a long bridge, combined with a multi-stage structure of a movable bridge, so that the movable bridge can be vertically lowered outside the wall in advance to align with the external long bridge, so that the cable can be laid without turning, and then the movable bridge is directly pulled back and bent, so that the cable can be bent in a local area. Compared with the existing laying method, the operation is simpler and more convenient, and the laying difficulty is greatly reduced, which is convenient for construction, and at the same time, scratches caused by contact with the turning structure during laying are avoided; When the movable bridge frame is bent, the conical block and the positioning groove are connected to form a predetermined shape, and then the movable cover plate is directly put on the outside for connection and fixation. This not only facilitates cable laying, but also facilitates the installation and construction of the bridge frame. When climbing over the low wall area, a stable installation effect can be achieved without fixing multiple structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] See also Figure 1 - Figure 8 As shown, the present invention provides a photovoltaic cable laying bridge and a method of using the same. Embodiment 1

The inside of the movable bridge 3 is provided with a rubber pad 320 to receive the cable to prevent scratches. The ends of the movable bridge 3 are provided with side plates 330 on both sides to connect with adjacent movable bridges 3. The short bridge 2 is slidably connected to the upper end of the long bridge 1, and is used to drive the movable bridge 3 to be lowered to the outside of the low wall, so that the cable only forms a regional bend at the end of the laying process to prevent scratches. Both ends of the movable bridge 3 are provided with 120° special-shaped bridges, which are connected to the extension frame 221 installed on the upper end of the short bridge 2 through the inner protrusion 220; The movable cover plate 310 is located on the outside of the movable bridge frame 3 and is a two-stage structure for closing the movable bridge frame 3. A conical block 341 is provided on the outside of the adapter 340 at one end of the movable bridge frame 3, and a positioning groove 342 is provided on the outside of the adapter 340 at the other end. The clamping connection between the conical block 341 and the positioning groove 342 is used to pre-fix the adjacent movable bridge frame 3 to 120°. The movable cover plate 310 is also used to be sleeved and fixed after the adjacent movable bridge frame 3 is pre-fixed.
[0014] The present embodiment provides a bridge frame that is convenient for laying cables. By utilizing the combination of a movable bridge frame 3, a short bridge frame 2 and a long bridge frame 1, the cables can be laid outside the low wall without turning or large-area contact with the bridge frame, thereby improving the convenience of laying and preventing scratches. In addition, adjacent movable bridge frames 3 can be combined into a multi-section turning structure to form a 360° turning angle, allowing the cables to easily cross the low wall without being restricted by its size, thereby reducing the difficulty of laying and improving the applicability of the bridge frame. The movable bridge frame 3 can realize automatic angle positioning, which facilitates the control of the laying angle and is beneficial to the subsequent fixing construction with the low wall, thereby reducing the difficulty of cable laying as a whole and ensuring the integrity of the cable during laying.
[0015] like Figure 3 As shown, vertically intersecting side pads 321 are provided on both sides of the rubber pad 320, which fit the two side walls of the movable bridge 3, so that the cable will not contact the side walls and cause scratches when laid, so as to achieve the effect of expanding the protection range.

[0017] like Figure 2 and Figure 4 as well as Figure 6 As shown, a folding plate 314 is provided inside the movable cover plate 310, which can bend and deform under the action of external force, and a guide plate 315 is provided at the bottom thereof to prevent it from getting stuck when contacting the side wall of the movable bridge frame 3, and a blocking pad 316 is provided on the inner side of the folding plate 314 for filling the gap to form a seal to increase the protection effect on the cable; elastic protrusions 317 are provided on the inner sides of the two side walls of the movable cover plate 310 for supporting the folding plate 314 to prevent loosening, and also for applying a tightening force to the folding plate 314 to increase the sealing performance, and a hollow cavity 318 is opened inside to provide space for the deformation of the folding plate 314 when the movable cover plate 310 is sleeved.
[0018] like Figure 8As shown, an outer hook plate 101 is provided at the upper end of the long bridge frame 1 to form a docking connection with an inner hook plate 201 at the lower end of the short bridge frame 2. After docking, the rubber material at the junction of the two is used to form a seal, so that after the movable bridge frame 3 is lifted to the top, the lower area does not require additional fixing operations to maintain a stable use effect. Embodiment 2
[0019] like Figure 1 - Figure 8 As shown, a method for using a photovoltaic cable laying bridge is as follows: S1: Preparation stage, the short bridge 2 is sleeved on the outer side of the upper end of the long bridge 1, and the adjacent movable bridge 3 is unfolded to form a vertical state; S2: In the pre-construction stage, the long bridge frame 1 is installed on the outside of the low wall, and a space for placing the movable bridge frame 3 is reserved above; S3: During the pre-laying process, the special-shaped bridge at the lower end of the movable bridge 3 is connected and fixed to the short bridge 2, and the unfolded movable bridge 3 is vertically hung on the outside of the low wall. At this time, the upper end of the special-shaped bridge protrudes outward to form a 120° inclination angle; S4: During the laying control phase, the cable is lowered longitudinally, during which it only contacts the protruding portion of the upper end of the special-shaped bridge and is protected by the rubber pad 320 inside, thereby avoiding scratches at the bends and large contact areas; S5: In the post-laying processing stage, the movable bridge 3 is pulled up and turned over to form a multi-stage turning structure above the low wall, and finally a 360° turning angle is formed. At this time, the conical block 341 is clamped in the positioning groove 342 to pre-fix the adjacent movable bridge 3; S6: During the fixing construction phase, two movable cover plates 310 are sleeved on the outer sides of the movable bridge frame 3 and merged, and then the adjacent movable cover plates 310 are fixed by the slide plate 313, thereby limiting every two adjacent movable bridge frames 3 to a rotation angle of 120°; S7: When the movable cover plate 310 is installed, the guide plate 315 drives the folding plate 314 to fold outward, and then under the elastic force and the squeezing action of the elastic protrusion 317, the blocking pad 316 fills the gap between the folding plate 314 and the movable bridge frame 3 to form a seal, and then the low wall is connected through the pillar 311; S8: In the final processing stage, the cables are dragged to adjust the spacing so that the cables are laid neatly, and finally the long cover plate 110 and the short cover plate 210 are installed outside the long bridge frame 1 and the short bridge frame 2 respectively.
