Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, in particular to a corrugated photovoltaic power generation tile. Background Art

[0002] At present, with the decline in the cost of photovoltaic cells, the construction and installation of distributed photovoltaic power generation systems in cities has become very popular. The construction of distributed power stations has largely shifted from the ground to buildings and structures, forming a variety of application scenarios such as roof photovoltaics, photovoltaic carports, photovoltaic curtain walls, photovoltaic corridors and photovoltaic containers. With the increase in application scenarios, new technical requirements have also been put forward for photovoltaic products, such as: waterproof function, beautiful shape matching the building, lightweight characteristics, modular easy installation, easy cleaning and maintenance, easy repair characteristics, good heat dissipation and moderate price. In order to meet the new market demand, various creative special products have been derived in the photovoltaic power generation product industry, such as: colored photovoltaic modules (increased color), waterproof photovoltaic brackets (increased waterproof function), frameless photovoltaic modules (enhanced self-cleaning ability), all-black photovoltaic modules (reduced the abruptness of the appearance color), photovoltaic flat tiles (enhanced the overall shape) and photovoltaic curved tiles (added antique glazed tile shape), etc.

[0003] However, although the characteristics of these featured products are prominent, they are indeed very scattered, and multiple characteristics cannot be concentrated in one product. At the same time, most photovoltaic products used on roofs, especially photovoltaic flat tiles and BIPV products, generally do not consider the natural ventilation capacity of the system, resulting in poor heat dissipation performance of photovoltaic products, affecting power generation. Although photovoltaic curved tiles have a strong three-dimensional sense, and are also very waterproof and water-conducting and self-cleaning, their curved shape is not well matched with the lamination packaging process of high-efficiency crystalline silicon cells, and there is a disadvantage of a high breakage rate of photovoltaic cells in production. If flexible power generation chips are used, the problem of low power generation efficiency per unit plane will be faced, which will lead to a significant increase in the cost of photovoltaic products per watt (power generation power and efficiency are reduced, but the cost of auxiliary materials remains unchanged). On the other hand, the existing photovoltaic curved tile products have photovoltaic cells in multiple directions, but only one way of power output. Since cells in different directions (multiple wave surfaces) will receive different intensities of solar radiation, the output power of the cells will be limited due to the barrel effect. At the same time, photovoltaic tile products under existing technologies must be installed individually on the purlins or keels of the roof, which means that installers can only install photovoltaic tile products one by one on the roof. The installation efficiency is low and it is not suitable for large-scale operations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a corrugated photovoltaic power generation tile which can be installed in an overlapping arrangement and combination, is beautiful and has a stable structure, and has good waterproof and natural ventilation and heat dissipation functions.

[0005] The technical solution of the present invention is:

[0006] A corrugated photovoltaic power generation tile is formed by splicing a plurality of corrugated photovoltaic modules arranged in a matrix, each of which includes a support frame and a corrugated photovoltaic power generation panel connected to the support frame;

[0007] The corrugated photovoltaic power generation panel includes a transparent cover, a plurality of photovoltaic cells, an integrated backplane and a junction box. The integrated backplane includes a substrate, a waterproof groove upper cover, a waterproof groove lower cover and a water retaining strip. Both the transparent cover and the substrate are corrugated bent plates. A plurality of photovoltaic cells are evenly arranged in a matrix and are bonded and fixed between the transparent cover and the substrate. The junction box is arranged on the bottom surface of the substrate. A plurality of photovoltaic cells are connected in series with the corresponding junction box. The waterproof groove upper cover and the waterproof groove lower cover are respectively fixedly connected to the two longitudinal edges of the substrate. When two transversely adjacent corrugated photovoltaic modules are docked, the waterproof groove upper cover is sealed on the waterproof groove lower cover and a drainage channel is formed in the middle. The water retaining strip is a corrugated bent strip structure, and the bottom end of the water retaining strip is fixedly connected to the transverse upper end of the substrate.

[0008] The support frame includes a rectangular frame, frame reinforcement ribs, multiple triangular brackets, an upper guide bar and a lower guide rail. The frame reinforcement ribs are fixedly connected to the inner circle of the rectangular frame to reinforce the rectangular frame. The two crossbeams of the rectangular frame are both rectangular tubes and the height of the rectangular tube at the longitudinal lower end is higher than the height of the rectangular tube at the longitudinal upper end, so that the top of the rectangular frame forms a structure with a low upper end and a high lower end. The heights of the multiple triangular brackets are consistent. A row of triangular brackets are arranged at the top ends of the two rectangular tubes along the tube axis direction. The two rows of triangular brackets on the two rectangular tubes are opposite to each other. The two longitudinal beams of the rectangular frame are both vertical plates connected between the two rectangular tubes. The upper guide bar and the lower guide rail are respectively arranged on the outer walls of the two vertical plates. When two laterally adjacent corrugated photovoltaic modules are butt-jointed, the upper guide bar is embedded in the guide groove of the lower guide rail.

[0009] The corrugated photovoltaic panel is mounted and adhesively fixed on the top of two rows of triangular brackets. The longitudinal lower end of the corrugated photovoltaic panel extends to the outside of the support frame, and the longitudinal upper end is mounted on the support frame. When two longitudinally adjacent corrugated photovoltaic modules are docked, the longitudinal lower end of the upper corrugated photovoltaic panel is mounted on the longitudinal upper end of the lower corrugated photovoltaic panel. Two transversely adjacent corrugated photovoltaic modules are connected and fixed by transverse connectors. The two ends of the transverse connectors are respectively inserted into two transversely docked rectangular tubes and are fixedly connected to the two rectangular tubes by locking bolts.

[0010] The waterproof trough upper cover is an inverted U-shaped structure, and the bottom end of the vertical part on the inner side of the waterproof trough upper cover is fixedly connected to the lateral end of the substrate. The waterproof trough lower cover is provided with three strip grooves with openings facing upwards, the middle strip groove is a drainage groove, the strip groove adjacent to the substrate is an upper cover card groove, and the strip groove away from the substrate is a sealing groove. When the horizontal part of the waterproof trough upper cover is sealed on the top of the waterproof trough lower cover, the vertical part of the outer side of the waterproof trough upper cover is clamped in the upper cover card groove of the waterproof trough lower cover, and an inverted L-shaped sealing strip is provided in the sealing groove. The vertical part of the inverted L-shaped sealing strip extends into the sealing groove, and the horizontal part of the inverted L-shaped sealing strip is located between the horizontal part of the waterproof trough upper cover and the top of the waterproof trough lower cover to achieve sealing. A row of rivets passes through the horizontal part of the waterproof trough upper cover and the waterproof trough lower cover in sequence to achieve the positioning connection between the waterproof trough upper cover and the waterproof trough lower cover.

[0011] There are at least two junction boxes on the corrugated photovoltaic power generation panel, and a plurality of photovoltaic cells with the same light-receiving surfaces are connected in series with each other and then connected to the corresponding junction boxes.

[0012] Each rectangular tube of the support frame is provided with strip grooves at both ends, and the strip grooves are opened on the bottom tube wall of the rectangular tube. When two transversely adjacent corrugated photovoltaic modules are connected and fixed by a transverse connecting piece, the two ends of the transverse connecting piece are respectively inserted into the two transversely connected rectangular tubes, and the connecting bolts pass through the corresponding strip grooves on the rectangular tubes and are threadedly connected to the transverse connecting piece.

[0013] The two vertical plates of the support frame are both provided with threading holes.

[0014] The upper guide bar of the support frame is an L-shaped guide bar, and the lower guide rail includes a horizontal limit guide bar and a lower guide bar arranged directly above the horizontal limit guide bar. The lower guide bar is an inverted L-shaped guide bar, and the horizontal part of the lower guide bar is parallel to the horizontal limit guide bar. When the upper guide bar is embedded in the guide groove of the lower guide rail, the horizontal part of the upper guide bar is supported on the horizontal limit guide bar, and the vertical part of the upper guide bar extends between the vertical part of the lower guide bar and the corresponding vertical plate.

[0015] A row of limit plates is fixedly provided on the outer wall of one of the rectangular tubes of the rectangular frame. When two longitudinally adjacent corrugated photovoltaic modules are docked, the row of limit plates is located between the rectangular tube at the lower end of the upper corrugated photovoltaic module and the rectangular tube at the upper end of the lower corrugated photovoltaic module, so that a spacing is formed between the support frames of the two longitudinally adjacent corrugated photovoltaic modules.

[0016] The frame reinforcement ribs are X-shaped reinforcement ribs, and the X-shaped reinforcement ribs are connected between two rectangular tubes.

[0017] When the multiple corrugated photovoltaic modules arranged in a matrix are installed, they are erected on multiple longitudinally extending composite purlins. Each composite purlin includes a purlin outer frame and a purlin core filler. The purlin outer frame is provided with a core filling groove with an upward opening. The purlin core filler is embedded in the core filling groove. A row of rivets passes through the horizontal part of the waterproof groove upper cover and the waterproof groove lower cover in sequence and is then driven into the purlin core filler to achieve a fixed connection between the waterproof groove upper cover, the waterproof groove lower cover and the composite purlin.

[0018] Advantages of the present invention:

[0019] (1) The integrated back plate of the corrugated photovoltaic power generation panel of the present invention is integrated with a waterproof groove upper cover, a waterproof groove lower cover and a water retaining strip. When two laterally adjacent corrugated photovoltaic modules are docked, the waterproof groove upper cover is sealed on the waterproof groove lower cover to form a drainage channel. The water retaining strip is arranged at the upper end of the integrated back plate to prevent rain splashing. The lower end of the integrated back plate is unobstructed, which facilitates rainwater to slide down along the light-receiving surface of the corrugated photovoltaic power generation panel. When it rains, it has the functions of preventing splashing, water accumulation and water leakage.

[0020] (2) The corrugated photovoltaic panels of the present invention are mounted and bonded to the top of two rows of triangular brackets. Most of the area of ​​the corrugated photovoltaic panels is suspended in the air, allowing air to circulate naturally, promoting heat dissipation and cooling of the photovoltaic tiles, and improving power generation efficiency.

[0021] (3) The photovoltaic power generation panel of the corrugated photovoltaic module of the present invention is a corrugated structure, that is, each inclined light-receiving surface is a flat structure, which is convenient for lamination packaging of photovoltaic cells and greatly reduces the breakage rate of photovoltaic cells during packaging.

[0022] (4) The corrugated photovoltaic panel of the present invention adopts a structure with a lower top and a higher bottom, which is convenient for arranging and installing multiple corrugated photovoltaic modules in a shingled manner, that is, the lower longitudinal end of one corrugated photovoltaic panel is mounted on the upper longitudinal end of another corrugated photovoltaic panel, and transverse connectors and rivets are used to connect and fix multiple corrugated photovoltaic modules in the transverse and longitudinal directions, so as to achieve the effect of imitating glazed tile roof, which is beautiful and has a stable structure.

[0023] (5) There are at least two junction boxes on the corrugated photovoltaic power generation panel of the present invention. A plurality of photovoltaic cells with the same light-receiving surface orientation are connected in series and then connected to the corresponding junction boxes. That is, the electrical output of the photovoltaic power generation panel is grouped and connected to different junction boxes according to the orientation of the photovoltaic cells. This avoids the barrel effect caused by the different orientations of the photovoltaic cells during power generation, and effectively solves the problem of limited power generation efficiency of curved photovoltaic tiles.
