Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a wiring structure of a photovoltaic curtain wall for building photovoltaic integration. Background Art

[0002] Photovoltaic panels make full use of reusable energy by absorbing sunlight and converting it into electrical energy for storage and use. The source of energy is more environmentally friendly and produces clean energy for people to use. Before using solar panels, they need to be installed and wired. During wiring, the wires are staggered and distributed outside the fixed junction box.

[0003] In actual use, a single photovoltaic panel is of little significance, and the amount of electrical energy converted after absorbing light energy is not much, so it is often necessary to use multiple photovoltaic panels together, and form these individual photovoltaic panels into a whole: a photovoltaic curtain wall, so as to generate more electricity by increasing the number, which can be used for use and generate economic value.

[0004] In actual use, when multiple photovoltaic panels are connected in an integrated manner, since photovoltaic panels do not have separate wiring and wiring structures, professional power workers are required to manually wire them, which is very time-consuming. Due to the large number of photovoltaic panels and the large amount of wiring work, it is easy to make connection errors and bring dangers. The wiring work needs to be very careful and the steps are cumbersome, and the overall operation is very heavy. At the same time, the wired lines have no protection measures between the two adjacent photovoltaic panels. After being exposed to wind and rain for a long time, they are prone to aging and breakage, making the photovoltaic panels unusable. Summary of the invention

A blind hole is formed on the side of the second fixing block 7 facing away from the first connection component, and a second wiring sleeve 23 is fixed in the blind hole.

[0033] It also includes a wire body 8, one end of which is fixedly sleeved with a first screw sleeve 18, the first screw sleeve 18 and the second screw sleeve 20 can be threadedly connected through a connecting sleeve 19, one end of the wire body 8 can be inserted into the first wiring sleeve 21, and the other end of the wire body 8 can be inserted into the second wiring sleeve 23.

[0034] A clamping assembly is slidably disposed on the first fixing seat 6 , and the clamping assembly can be slidably clamped on the second fixing seat 10 .

[0035] The clamping assembly includes an arc-shaped plate 2, and a slot 27 is provided at the upper end of the first fixing seat 6 and the upper end of the second fixing seat 10. A slide bar 17 is fixed to the lower end of the arc-shaped plate 2, and the slide bar 17 can slide in the slot 27 at the upper end of the first fixing seat 6 and the upper end of the second fixing seat 10.

[0036] The arc plate 2 is hingedly connected with a covering assembly at one end. The covering assembly includes a plurality of connection blocks 11, two adjacent connection blocks 11 are hingedly connected by a shaft 3, a connection block 11 adjacent to the arc plate 2 is hingedly connected to the arc plate 2 by the shaft 3, and the covering assembly and the arc plate 2 are enclosed to form a tubular structure. When the clamping assembly is slidably clamped on the second fixing seat 10, the covering assembly is limited by the limiting assembly on the second fixing block 7.

[0037] The limiting assembly includes a second limiting rod 12 fixed on the second fixed block 7, the length direction of the second limiting rod 12 is parallel to the sliding direction of the arc plate 2 on the second fixed seat 10, and a limiting groove 15 is provided on the connecting block 11 at the free end of the covering assembly. During the movement of the arc plate 2 and the covering assembly toward the second fixed block 7, the second limiting rod 12 can be inserted into the limiting groove 15.

[0038] A first limiting rod 26 corresponding to the second limiting rod 12 is fixed on the first fixing block 9 . When the arc plate 2 and the covering assembly move toward the first fixing block 9 , the first limiting rod 26 can be inserted into the limiting groove 15 .

[0039] A connecting plate 13 is fixed to the lower end of the arc plate 2 on one side of the slide bar 17, a through hole 14 is opened on the connecting plate 13, a first opening 25 is opened on the first fixing seat 6, and a second opening 24 is opened on the second fixing seat 10.

After the arc plate 2 and the connecting plate 13 move toward the first fixing block 9, the first opening 25 can be concentric with the through hole 14.

[0040] The connecting blocks 11 are all fixed with protrusions 16. After the covering assembly and the arc plate 2 are combined into a tubular structure, the protrusions 16 are located between the covering assembly and the arc plate 2. Elastic blocks 22 are fixed on the protrusions 16, and the elastic blocks 22 can squeeze and clamp the wire body 8 passing through the clamping assembly.

[0041] When two adjacent photovoltaic panels 1 are connected, the first connection component of one photovoltaic panel 1 is arranged adjacent to the second connection component of the other photovoltaic panel 1 .

[0042] In the initial state of the clamping assembly, the slide bar 17 is slidably disposed in the slot 27 on the first fixing seat 6, the through hole 14 is concentric with the first opening 25, and the pin passes through the through hole 14 and is inserted into the first opening 25. At this time, the first limiting rod 26 is inserted into the limiting slot 15.

[0043] Before connecting two adjacent photovoltaic panels 1 with the wire body 8, move the two photovoltaic panels 1 so that the blind hole on the second fixing block 7 is concentric with the slotted hole on the first fixing block 9, and then pull out the pin that penetrates the through hole 14, so that the curved plate 2, the connecting plate 13 and the covering assembly move toward the second connecting assembly of the other photovoltaic panel 1. When the first limiting rod 26 is withdrawn from the limiting groove 15, the multiple connecting blocks 11 of the covering assembly can be rotated, and then the wire body 8 is placed in the curved plate 2, and both ends of the wire body 8 are located outside the curved plate 2, and then the covering assembly and the curved plate 2 are combined to form a tubular structure.

At this time, the clamping assembly is fixedly connected to the second fixing seat 10. At the same time, the clamping assembly maintains the clamping of the wire body 8. After the wire body 8 is pulled, it can prevent the end of the wire body 8 on the side of the second fixing block 7 from withdrawing from the second wiring sleeve 23, and the connection stability performance of the wire body 8 and the second wiring sleeve 23 is good.

[0045] Then, the end of the wire body 8 on one side of the first fixing block 9 is inserted into the first wiring sleeve 21, and the first screw sleeve 18 and the second screw sleeve 20 are threadedly connected by the connecting sleeve 19. At this point, the connection between two adjacent photovoltaic panels 1 is completed.

[0046] The clamping assembly can cover the portion of the wire body 8 corresponding to the space between two adjacent photovoltaic panels 1, thereby preventing the wire body 8 corresponding to the space between two adjacent photovoltaic panels 1 from being exposed to the sun for a long time and increasing the service life of the wire body 8.
