Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 2, a distributed photovoltaic power generation assembly 10 includes: a roof tile 11, a plurality of photovoltaic power generation units 12 and a bracket 13. The photovoltaic power generation unit 12 is used to convert solar energy into electrical energy. The bracket 13 is adapted to be mounted to the shingle tile 11 to support a plurality of photovoltaic power generation units 12. A plurality of photovoltaic power generation units 12 are connected in series to once incorporate the converted electrical energy into the grid.
In this embodiment, the roof tile 11 is a color steel roof tile 11. The color steel roof plate tile 11 is formed by rolling a color coated steel coil by a special machine and then is arranged on a roof purline, thereby forming a waterproof color steel tile roof, wherein the color steel tiles commonly used at present have an angle relaxation type color steel tile, a 180-degree occlusion color steel tile and a 360-degree occlusion color steel tile. The bracket 13 includes: a plurality of aluminum alloy columns 132, a plurality of aluminum alloy beams 133, a plurality of aluminum alloy rails 134, and a plurality of aluminum alloy compacts 135. The aluminum alloy upright posts 132 are fixed on the color steel roof plate tiles 11. The plurality of aluminum alloy beams 133 are fixed to the plurality of aluminum alloy columns 132 through a plurality of aluminum alloy compacts 135, respectively. Aluminum alloy rails 134 are formed on both sides of the aluminum alloy columns 132 to support the plurality of photovoltaic power generation units 12. The aluminum alloy rail 134 is formed with a drain groove 1341 for draining water. The bracket 13 is formed with a plurality of unit mounting modules 131 for mounting the plurality of photovoltaic power generation units 12, respectively. The photovoltaic power generation unit 12 is mounted on the aluminum alloy rail 134 in the unit installation module 131. The bracket 13 is stable in the manner of fixing the base, and is made of aluminum alloy, so that the entire weight is light, the texture is hard, and the support performance is good. The bracket 13 made of aluminum alloy has low cost, high corrosion resistance and stable wind load and snow load resistance. Meanwhile, the bracket 13 with the structure is simple in structure and convenient to mount.
As a specific embodiment, the aluminum alloy upright 132 is clamped to the color steel roof tile 11 by an aluminum alloy clamp and the aluminum alloy upright 132 is fixed to the color steel roof tile 11 by stainless steel screws 1353. In order to avoid damaging the waterproof layer of the original building and influencing the normal production work, the connection between the color steel roof plate tiles 11 and the bracket 13 is mainly fixed by a special fixture matched with the tile shapes of the color steel roof plate tiles 11, so as to ensure the stability and reliability of the whole bracket 13 system.
As a preferred embodiment, the thickness value range of the aluminum alloy clamp is set to be more than 5mm and less than 8mm, so that the safety and stability of the whole bracket 13 system are ensured.
Further, the thickness value range of the aluminum alloy guide rail 134 is set to 1.8mm or more and 2.2mm or less. Since the aluminum alloy guide rail 134 is a secondary structure for fixing with the photovoltaic power generation unit 12, and is an important component for ensuring the stability of the photovoltaic power generation unit 12, it needs to be determined by calculation according to local wind pressure, snow pressure and other load conditions, and a guide rail with a thickness not less than 1.8mm is selected. Here, the thickness value range of the aluminum alloy guide rail 134 is set to be 1.8mm or more and 2.2mm or less, which ensures the stability of the aluminum alloy guide rail 134 and avoids the overweight of the aluminum alloy guide rail 134.
As a specific embodiment, the aluminum alloy compact 135 includes: an upper press block 1351 and a lower press block 1352. The upper and lower press blocks 1351 and 1352 together clamp two adjacent aluminum alloy beams 133 between the upper and lower press blocks 1351 and 1352. The upper pressing block 1351 and the lower pressing block 1352 are screwed into the upper pressing block 1351, the lower pressing block 1352 and the aluminum alloy upright 132 in sequence through stainless steel screws 1353 to fix the aluminum alloy beam 133 to the aluminum alloy upright 132. Such a fixing structure is simple and stable, and can improve the installation efficiency of the distributed photovoltaic power generation module 10.
Further, the upper press piece 1351 is also formed with a limiting protrusion 1354. The limiting protrusions 1354 are used for limiting the installation position of the aluminum alloy cross beam 133, and installation accuracy and efficiency are higher.
As a specific embodiment, the photovoltaic power generation units 12 located on the south side of the color steel roof tile 11 are laid with an angle of inclination of 8 degrees to the horizontal and facing south. The photovoltaic power generation units 12 located on the north side of the color steel roof tile 11 face south and form an inclination angle of 3 degrees with the horizontal plane when being laid. The photovoltaic power generation units 12 located on the east and west sides of the color steel roof panel tile 11 are disposed along the surface of the color steel roof panel tile 11. The photovoltaic power generation unit 12 is arranged in this way, so that the distributed photovoltaic power generation assembly 10 can fully utilize solar energy and has high electric energy conversion degree.
In a specific embodiment, a bypass diode is connected in parallel between the positive electrode and the negative electrode of the plurality of photovoltaic power generation units 12. The bypass diode is provided on the lower side of the photovoltaic power generation unit 12. The bypass diode has the functions of: when the cells of the distributed photovoltaic power generation assembly 10 generate hot spot effect and cannot generate power, the bypass function is realized, so that the current generated by the cells of other distributed photovoltaic power generation assemblies 10 can flow out of the diodes, the solar power generation system can continue to generate power, and the situation that a power generation circuit cannot be communicated due to the problem of one cell is avoided.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
