Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, relates to photovoltaic railing technology, and specifically is a photovoltaic railing wiring structure. Background Art

[0002] Photovoltaic railings are railings that also have power generation capabilities. They primarily improve existing railings by installing photovoltaic panels on them to fully utilize solar energy. The detailed structure of photovoltaic railings is described in patent application number CN201822258970.8, which discloses a photovoltaic railing comprising: a plurality of vertical poles spaced apart; photovoltaic modules positioned between adjacent vertical poles to form a guardrail; and lighting devices connected to the photovoltaic modules to supply power to the lighting devices.

[0003] Refer to the patent document with application number CN202323359021.6, which discloses a photovoltaic railing based on building photovoltaic integration, and specifically discloses that the photovoltaic panel is conductively connected to the conductive cable to conduct the current generated by the photovoltaic panel; the conductive cable is arranged inside the transverse railing body. The transverse railing body is divided into at least a first area and a second area; the conductive cable is arranged in the first area. It can be seen that the photovoltaic railings in the prior art are basically wired along the transverse direction of the railing when wiring. At the same time, there are also records in the prior art that the conductive cables are laid along the transverse handrails, and the conductive cables are hidden in the handrails. This way of laying the conductive cables along the transverse direction means that the conductive cables can only be laid along the top or bottom end of the photovoltaic railing. Since the length of the photovoltaic railing is generally long, the amount of conductive cables used when laying the cables horizontally is very large. Utility Model Content

[0004] As described in the above background technology, when laying conductive cables for photovoltaic railings in the prior art, they are generally laid along the horizontal direction of the photovoltaic railings. Since the length of photovoltaic railings is generally long, there is a technical problem that a very large amount of conductive cables is used. To address this technical problem, the present utility model proposes a photovoltaic railing wiring structure.

[0005] The utility model provides a column frame on the backlight side of the photovoltaic panel, connecting the column frame cavity with the handrail frame cavity above the photovoltaic panel. This allows the conductive cable to pass through the handrail frame and extend into the column frame cavity. The conductive cable can then extend from the top of the column frame to the bottom of the column frame, allowing the conductive cable to be laid longitudinally along the column frame. Compared to the prior art method of laying conductive cables transversely along the photovoltaic railing, laying the conductive cables longitudinally can significantly reduce the amount of conductive cable used, saving costs.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0017] It is further defined that the photovoltaic railing wiring structure also includes an adjusting screw, which is arranged on the side of the column frame and is used to fix the column frame to the column.

[0018] It is further defined that the bottom of the column and the base are both embedded and fixed in the building filling layer.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be further explained below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments described below.

[0033] Example 1

[0034] See also Figure 1 The photovoltaic railing wiring structure of this embodiment includes a photovoltaic panel 8, a photovoltaic junction box 11, a handrail frame 13 and a column frame 14. The column frame 14 is arranged on the backlight side of the photovoltaic panel 8; the handrail frame 13 is arranged above the column frame 14, and the photovoltaic junction box 11 is placed in the handrail frame 13; the top of the photovoltaic panel 8 extends into the handrail frame 13 and is electrically connected to the photovoltaic junction box 11; the cavity of the handrail frame 13 is connected to the cavity of the column frame 14.

The opening of the second accommodating groove 1303 faces downward, so that the top of the photovoltaic panel 8 extends into the second accommodating groove 1303; the second mounting groove 1302 is used to accommodate the connecting parts connecting the handrail frame 13 and the column frame 14. The connecting parts can be detachable connections such as screws, bolts, and latches. The opening (window) of the second mounting groove 1302 faces upward, which is convenient for the installer to operate. An upper buckle cover 12 is provided at the opening (window) of the second mounting groove 1302. The upper buckle cover 12 is used to close the second mounting groove 1302 to achieve beautiful appearance, rainproof and other effects.

[0036] The photovoltaic junction box 11 is connected to a wiring cable 15, which is electrically connected to one end of a conductive cable 16. The other end of the conductive cable 16 passes through the cavity of the handrail frame 13 and extends to the cavity of the column frame 14; the conductive cable 16 extends along the top of the column frame 14 to the bottom of the column frame 14, so that the conductive cable 16 is arranged along the longitudinal direction of the column frame 14. A wire hole 1301 is provided on the partition between the second mounting groove 1302 and the second accommodating groove 1303.

[0037] This embodiment sets a column frame 14 on the backlight side of the photovoltaic panel 8 and connects the cavity of the column frame 14 with the cavity of the handrail frame 13, so that the conductive cable 16 can pass through the handrail frame 13 and extend into the column frame 14, and can extend along the top of the column frame 14 to the bottom of the column frame 14, so that the conductive cable 16 is arranged longitudinally along the column frame 14, thereby realizing the longitudinal arrangement of the conductive cable 16 along the photovoltaic railing.

That is, the conductive cables 16 cannot be directly observed along the front of the photovoltaic panel 8. This is applicable to both translucent and opaque photovoltaic panels 8 and does not affect the aesthetics of the photovoltaic railing.
